Risk [Text Block]

MARKET RISK. Market risk is the risk that a particular investment, or Fund Shares in general, may fall in value. Securities are subject to market fluctuations caused by real or perceived adverse economic, political, and regulatory factors or market developments, changes in interest rates, disruptions to trade, impositions of tariffs and perceived trends in securities prices. Fund Shares could decline in value or underperform other investments. In addition, local, regional or global events such as war, acts of terrorism, market manipulation, government defaults, government shutdowns, regulatory actions, political changes, diplomatic developments, the imposition of sanctions and other similar measures, spread of infectious diseases or other public health issues, recessions, natural disasters, or other events could have a significant negative impact on the Fund and its investments. Any of such circumstances could have a materially negative impact on the value of Fund Shares, the liquidity of an investment, and may result in increased market volatility. During any such events, Fund Shares may trade at increased premiums or discounts to their net asset value, the bid/ask spread on Fund Shares may widen and the returns on investment may fluctuate.

Roundhill Bitcoin Covered Call Strategy ETF | COVERED CALL STRATEGY RISK  
Prospectus [Line Items]  
Risk [Text Block]

COVERED CALL STRATEGY RISK. A covered call strategy involves writing (selling) covered call options in return for the receipt of premiums. The seller of the option gives up the opportunity to benefit from price increases in the underlying instrument above the exercise price of the options, but continues to bear the risk of underlying instrument price declines. The premiums received from the options may not be sufficient to offset any losses sustained from underlying instrument price declines, over time. As a result, the risks associated with writing covered call options may be similar to the risks associated with writing put options. Exchanges may suspend the trading of options during periods of abnormal market volatility. Suspension of trading may mean that an option seller is unable to sell options at a time that may be desirable or advantageous to do so.

 

The covered call strategy utilized by the Fund is “synthetic” because the Fund’s exposure to the price return of the Bitcoin ETFs is derived through options exposure, rather than direct holdings of the shares of the Bitcoin ETFs. Because such exposure is synthetic, it is possible that the Fund’s participation in the price return of the Bitcoin ETFs may not be as precise as if the Fund were directly holding shares of the Bitcoin ETFs.

Roundhill Bitcoin Covered Call Strategy ETF | OPTIONS RISK  
Prospectus [Line Items]  
Risk [Text Block]

OPTIONS RISK. The use of options involves investment strategies and risks different from those associated with ordinary portfolio securities transactions and depends on the ability of the Fund’s portfolio managers to forecast market movements correctly. The prices of options are volatile and are influenced by, among other things, actual and anticipated changes in the value of the underlying instrument, or in interest or currency exchange rates, including the anticipated volatility, which in turn are affected by fiscal and monetary policies and by national and international political and economic events. The effective use of options also depends on the Fund’s ability to terminate option positions at times deemed desirable to do so. There is no assurance that the Fund will be able to effect closing transactions at any particular time or at an acceptable price. In addition, there may at times be an imperfect correlation between the movement in values of options and their underlying securities and there may at times not be a liquid secondary market for certain options.

Roundhill Bitcoin Covered Call Strategy ETF | LIQUIDITY RISK  
Prospectus [Line Items]  
Risk [Text Block]

LIQUIDITY RISK. The market for Bitcoin ETF Options is still developing and may be subject to periods of illiquidity. During such times it may be difficult or impossible to buy or sell a position at the desired price. Market disruptions or volatility can also make it difficult to find a counterparty willing to transact at a reasonable price and sufficient size. Illiquid markets may cause losses, which could be significant. The large size of the positions which the Fund may acquire increases the risk of illiquidity, may make its positions more difficult to liquidate, and may increase the losses incurred while trying to do so. Such large positions also may impact the price of Bitcoin ETF Options.

Roundhill Bitcoin Covered Call Strategy ETF | BITCOIN ETF RISKS  
Prospectus [Line Items]  
Risk [Text Block]

BITCOIN ETF RISKS. The Fund will have significant exposure to the Bitcoin ETFs through its Bitcoin ETF Option positions. Accordingly, the Fund will be subject to the risks of the Bitcoin ETFs, set forth below. In addition to these risks, the Bitcoin ETFs are also subject to the following risks to which the Fund is also subject, which are described within the section entitled “Principal Risks”: Active Market Risk, Asset Class Risk, Concentration Risk, Cybersecurity Risk, Legislation and Litigation Risk, Operational Risk and Structural ETF Risk.

 

BITCOIN RISK. Bitcoin remains a volatile and evolving asset subject to significant market fluctuations, uncertainty, and speculative investment interest. Although increased institutional adoption and regulatory clarity have recently improved market stability and broader acceptance, the value of bitcoin continues to be influenced substantially by market sentiment, speculative demand, and macroeconomic factors rather than traditional fundamental analysis alone. The further development and sustained acceptance of the Bitcoin network are dependent on a variety of complex factors, including technological advancements, regulatory developments, institutional participation, and broader public adoption. While regulatory oversight of bitcoin and related digital assets has notably increased, particularly in jurisdictions like the United States and Europe, the global regulatory landscape remains fragmented. Sudden or significant regulatory actions—including new legislation, enforcement actions against key market participants, or policy shifts—can still materially impact bitcoin’s valuation and liquidity. Bitcoin markets remain susceptible to manipulation, fraud, theft, cybersecurity incidents, and operational disruptions, especially on trading platforms that lack robust regulatory oversight or proper cybersecurity standards. Furthermore, a significant concentration of bitcoin holdings among a limited number of large holders, often referred to as “whales,” continues to pose risks of price volatility or manipulation through coordinated transactions. Technological risks remain inherent in bitcoin and its underlying blockchain network. While advancements such as Layer 2 scaling solutions (e.g., the Lightning Network) have made meaningful progress toward addressing scalability and usability concerns, these technologies are still evolving and carry risks of technical vulnerabilities, hacking, and operational failures that may undermine confidence or negatively affect bitcoin’s value. The potential for blockchain forks—where disagreements among developers and stakeholders lead to competing blockchains—continues to exist. Although fewer contentious forks have occurred in recent times, such events could reoccur, introducing market confusion, diluting value, or weakening confidence in the Bitcoin blockchain. Competition from alternative blockchain networks and digital assets remains strong. Networks like Ethereum and other blockchain platforms with smart contract capabilities, privacy features, or superior scalability may attract broader adoption, thereby reducing bitcoin’s relative attractiveness or limiting its potential as an alternative payment system or digital store of value. Any of these risks, individually or collectively, could materially and adversely affect the acceptance and market value of bitcoin, consequently impacting the value of shares in Bitcoin ETFs or related investment products.

 

CUSTODY RISK. Security breaches, computer malware and computer hacking attacks have been a prevalent concern in relation to digital assets. The bitcoin held by the Bitcoin ETFs’ custodian will likely be an appealing target to hackers or malware distributors seeking to destroy, damage or steal the Bitcoin ETFs’ bitcoins. To the extent that the Bitcoin ETFs and their service providers are unable to identify and mitigate or stop new security threats or otherwise adapt to technological changes in the digital asset industry, a Bitcoin ETF’s bitcoins may be subject to theft, loss, destruction or other attack. The Bitcoin ETFs have put security procedures in place to prevent such theft, loss or destruction, including but not limited to, offline storage, or cold storage, multiple encrypted private key “shards”, and other measures. Nevertheless, the security procedures cannot guarantee the prevention of any loss due to a security breach, software defect or act of God that may be borne by the Bitcoin ETFs and the security procedures may not protect against all errors, software flaws or other vulnerabilities in a Bitcoin ETF’s technical infrastructure, which could result in theft, loss or damage of its assets. The Bitcoin ETFs do not control the operations of their service providers or their implementation of such security procedures and there can be no assurance that such security procedures will actually work as designed or prove to be successful in safeguarding a Bitcoin ETF’s assets against all possible sources of theft, loss or damage. Assets not held in cold storage, such as assets held in a trading account, may be more vulnerable to security breach, hacking or loss than assets held in cold storage. Furthermore, assets held in a trading account are held on an omnibus, rather than segregated basis, which creates greater risk of loss. The security procedures and operational infrastructure may be breached due to the actions of outside parties, error or malfeasance of an employee of a Bitcoin ETF’s service providers, and, as a result, an unauthorized party may obtain access to the Bitcoin ETF’s account at the custodian where its bitcoin is held, the relevant private keys (and therefore bitcoin) or other data or property of a Bitcoin ETF. Additionally, outside parties may attempt to fraudulently induce employees of a Bitcoin ETF or its service providers to disclose sensitive information in order to gain access to a Bitcoin ETF’s infrastructure. As the techniques used to obtain unauthorized access, disable or degrade service, or sabotage systems change frequently, or may be designed to remain dormant until a predetermined event and often are not recognized until launched against a target, a Bitcoin ETF and its service providers may be unable to anticipate these techniques or implement adequate preventative measures.

 

DIGITAL ASSET TRADING PLATFORMS RISK. Digital asset trading platforms remain relatively new and vary significantly in terms of regulation, transparency, operational stability, and compliance standards. While certain prominent trading platforms—particularly those based in the United States—have substantially improved transparency, compliance, and regulatory adherence, many platforms still operate internationally or offshore with significantly less stringent oversight. Platforms located outside the United States may be subject to minimal or inconsistent regulatory enforcement and often do not provide sufficient public information regarding their management structure, ownership, financial stability, cybersecurity practices, or compliance controls. Despite increased institutional involvement, enhanced security measures, and more standardized operating practices adopted by leading platforms, digital asset exchanges continue to be vulnerable to cybersecurity threats, hacking incidents, fraudulent activities, operational disruptions, and other technical risks. High-profile failures, breaches, or shutdowns of major trading platforms or custodians—such as those arising from fraud, cybersecurity incidents, regulatory enforcement actions, or insolvency—can significantly reduce investor confidence, increase market volatility, and potentially trigger contagion effects across the digital asset ecosystem. Regulatory developments and enforcement actions continue to shape the landscape in which digital asset platforms operate. Recent regulatory scrutiny has heightened globally, particularly in jurisdictions with substantial trading volumes, such as the United States, Europe, and Asia. Increased regulatory oversight, while potentially positive for market stability in the long run, can create short-term disruption, reduce liquidity, prompt platform closures, or alter business models substantially, thereby affecting the prices of digital assets, including bitcoin. Investors should be aware that trading or custodying bitcoin on less transparent or poorly regulated platforms increases the risk of losing access to digital assets due to platform insolvency, hacking incidents, regulatory intervention, or operational failure. Although improvements have been made, the digital asset marketplace remains inherently riskier than traditional financial markets, and investors may have limited recourse if a digital asset trading platform fails or is compromised.

 

IRREVOCABILITY OF TRANSACTIONS RISK. Bitcoin transactions are typically not reversible without the consent and active participation of the recipient of the transaction. Once a transaction has been verified and recorded in a block that is added to the Bitcoin blockchain, an incorrect transfer or theft of bitcoin generally will not be reversible and a Bitcoin ETF may not be capable of seeking compensation for any such transfer or theft. It is possible that, through computer or human error, or through theft or criminal action, a Bitcoin ETF’s bitcoin could be transferred from the Bitcoin ETF’s account at its custodian in incorrect amounts or to unauthorized third parties, or to uncontrolled accounts.

 

TRADING HALT RISK. Trading in shares of a Bitcoin ETF on U.S. securities exchanges may be halted due to market conditions or for reasons that, in the view of an exchange, make trading in shares of the Bitcoin ETF inadvisable. In addition, trading of shares of a Bitcoin ETF on securities exchanges is subject to trading halts caused by extraordinary market volatility pursuant to an exchange’s “circuit breaker” rules. Shares of a Bitcoin ETF may be at a higher risk of a trading halt due to the volatility of bitcoin. In the event that shares of a Bitcoin ETF are subject to a trading halt, the Fund’s ability to pursue its principal investment strategy may be impaired and the Fund may be negatively affected.

 

VOLATILITY RISK. The price of bitcoin remains highly volatile and subject to significant price fluctuations. While recent increases in institutional adoption, clearer regulatory frameworks, and broader market acceptance have contributed to greater stability relative to earlier periods, the price of bitcoin continues to be influenced by rapid shifts in market sentiment, regulatory developments, macroeconomic conditions, technological advancements, and unforeseen events. The market price of bitcoin has historically experienced dramatic highs and lows over short periods, often with limited or no identifiable catalyst. Given the evolving nature of digital asset markets, price volatility may be amplified by external factors such as changes in global financial markets, geopolitical events, regulatory enforcement actions, or significant technological or security incidents. Furthermore, speculative trading, leveraged positions, and derivatives markets tied to bitcoin continue to contribute to potential volatility. Investors should remain aware that sudden, substantial price movements may occur at any time, potentially leading to significant losses. Consequently, investments linked directly or indirectly to bitcoin, including Bitcoin ETFs, may experience heightened volatility compared to traditional investment products.

Roundhill Bitcoin Covered Call Strategy ETF | ACTIVE MANAGEMENT RISK  
Prospectus [Line Items]  
Risk [Text Block]

ACTIVE MANAGEMENT RISK. The Fund is actively-managed and its performance reflects investment decisions that the Adviser and/or Sub-Adviser makes for the Fund. Such judgments about the Fund’s investments may prove to be incorrect. If the investments selected and the strategies employed by the Fund fail to produce the intended results, the Fund could underperform as compared to other funds with similar investment objectives and/or strategies, or could have negative returns.

Roundhill Bitcoin Covered Call Strategy ETF | ACTIVE MARKET RISK  
Prospectus [Line Items]  
Risk [Text Block]

ACTIVE MARKET RISK. Although Fund Shares are listed for trading on the Exchange, there can be no assurance that an active trading market for Fund Shares will develop or be maintained. Fund Shares trade on the Exchange at market prices that may be below, at or above the Fund’s net asset value. Securities, including Fund Shares, are subject to market fluctuations and liquidity constraints that may be caused by such factors as economic, political, or regulatory developments, changes in interest rates, and/or perceived trends in securities prices. Fund Shares could decline in value or underperform other investments.

Roundhill Bitcoin Covered Call Strategy ETF | ASSET CLASS RISK  
Prospectus [Line Items]  
Risk [Text Block]

ASSET CLASS RISK. Securities and other assets in the Fund’s portfolio may underperform in comparison to the general financial markets, a particular financial market or other asset classes.

Roundhill Bitcoin Covered Call Strategy ETF | ASSIGNMENT RISK  
Prospectus [Line Items]  
Risk [Text Block]

ASSIGNMENT RISK. In response to a notification of an option holder’s desire to exercise the option held, the OCC may randomly assign the exercise notice to a clearing member, which must then assign, randomly or on a first-in-first-out basis, the obligation to a customer who has written that particular option. If the Fund is assigned an exercise notice, the Fund pays the buyer the difference between the option price on the exercise date and the option price when written by the Fund. As a result, the Fund may be forced to settle a written option position at an inopportune time and at a cost to the Fund, both of which could adversely affect the Fund’s performance and ability to track the performance of the Bitcoin ETFs.

Roundhill Bitcoin Covered Call Strategy ETF | CLEARING MEMBER DEFAULT RISK  
Prospectus [Line Items]  
Risk [Text Block]

CLEARING MEMBER DEFAULT RISK. Transactions in some types of derivatives, including the options held by the Fund, are required to be centrally cleared (“cleared derivatives”). In a transaction involving cleared derivatives, the Fund’s counterparty is a clearinghouse, such as the OCC, rather than a bank or broker. Since the Fund is not a member of clearinghouses, and only members of a clearinghouse (“clearing members”) can participate directly in the clearinghouse, the Fund will hold cleared derivatives through accounts at clearing members. With regard its cleared derivatives positions, the Fund will make payments (including margin payments) to, and receive payments from, a clearinghouse through their accounts at clearing members. Customer funds held at a clearing organization in connection with any option contracts are held in a commingled omnibus account and are not identified to the name of the clearing member’s individual customers. As a result, assets deposited by the Fund with any clearing member as margin for its options position may, in certain circumstances, be used to satisfy losses of other clients of the Fund’s clearing member. In addition, although clearing members guarantee performance of their clients’ obligations to the clearinghouse, there is a risk that the assets of the Fund might not be fully protected in the event of the clearing member’s bankruptcy. The Fund is also subject to the risk that a limited number of clearing members are willing to transact on the Fund’s behalf, which heightens the risks associated with a clearing member’s default. If a clearing member defaults, the Fund could lose some or all of the benefits of a transaction entered into by the Fund with the clearing member. The loss of a clearing member for the Fund to transact with could result in increased transaction costs and other operational issues that could impede the Fund’s ability to implement its investment strategy. If the Fund cannot find a clearing member to transact with on the Fund’s behalf, the Fund may be unable to effectively implement its investment strategy.

Roundhill Bitcoin Covered Call Strategy ETF | CONCENTRATION RISK  
Prospectus [Line Items]  
Risk [Text Block]

CONCENTRATION RISK. The Fund may be susceptible to an increased risk of loss, including losses due to adverse events that affect the Fund’s investments more than the market as a whole, to the extent that the Fund’s investments are concentrated in investments that provide exposure to bitcoin.

Roundhill Bitcoin Covered Call Strategy ETF | COUNTERPARTY RISK  
Prospectus [Line Items]  
Risk [Text Block]

COUNTERPARTY RISK. Fund transactions involving a counterparty are subject to the risk that the counterparty will not fulfill its obligation to the Fund. Counterparty risk may arise because of the counterparty’s financial condition (i.e., financial difficulties, bankruptcy, or insolvency), market activities and developments, or other reasons, whether foreseen or not. A counterparty’s inability to fulfill its obligation may result in significant financial loss to the Fund. The Fund may be unable to recover its investment from the counterparty or may obtain a limited recovery, and/or recovery may be delayed.

Roundhill Bitcoin Covered Call Strategy ETF | Credit Risk [Member]  
Prospectus [Line Items]  
Risk [Text Block]

CREDIT RISK. An issuer or other obligated party of a debt security may be unable or unwilling to make dividend, interest and/or principal payments when due. In addition, the value of a debt security may decline because of concerns about the issuer’s ability or unwillingness to make such payments.

Roundhill Bitcoin Covered Call Strategy ETF | CURRENT MARKET CONDITIONS RISK  
Prospectus [Line Items]  
Risk [Text Block]

CURRENT MARKET CONDITIONS RISK. Current market conditions risk is the risk that a particular investment, or Fund Shares in general, may fall in value due to current market conditions. As a means to fight inflation, which remains at elevated levels, the Federal Reserve and certain foreign central banks have raised interest rates; however, the Federal Reserve has recently lowered interest rates and may continue to do so. U.S. regulators have proposed several changes to market and issuer regulations which would directly impact the Fund, and any regulatory changes could adversely impact the Fund’s ability to achieve its investment strategies or make certain investments. Recent and potential future bank failures could result in disruption to the broader banking industry or markets generally and reduce confidence in financial institutions and the economy as a whole, which may also heighten market volatility and reduce liquidity. Additionally, challenges in commercial real estate markets, including rising interest rates, declining valuations and increasing vacancies, could have a broader impact on financial markets. The ongoing adversarial political climate in the United States, as well as political and diplomatic events both domestic and abroad, have and may continue to have an adverse impact the U.S. regulatory landscape, markets and investor behavior, which could have a negative impact on the Fund’s investments and operations. The change in administration resulting from the 2024 United States national elections could result in significant impacts to international trade relations, tax and immigration policies, and other aspects of the national and international political and financial landscape, which could affect, among other things, inflation and the securities markets generally. Other unexpected political, regulatory and diplomatic events within the U.S. and abroad may affect investor and consumer confidence and may adversely impact financial markets and the broader economy. For example, ongoing armed conflicts between Russia and Ukraine in Europe and among Israel, Iran, Hamas and other militant groups in the Middle East, have caused and could continue to cause significant market disruptions and volatility within the markets in Russia, Europe, the Middle East and the United States. The hostilities and sanctions resulting from those hostilities have and could continue to have a significant impact on certain Fund investments as well as Fund performance and liquidity. The economies of the United States and its trading partners, as well as the financial markets generally, may be adversely impacted by trade disputes, including the imposition of tariffs, and other matters. For example, the United States has imposed trade barriers and restrictions on China. In addition, the Chinese government is engaged in a longstanding dispute with Taiwan, continually threatening an invasion. If the political climate between the United States and China does not improve or continues to deteriorate, if China were to attempt invading Taiwan, or if other geopolitical conflicts develop or worsen, economies, markets and individual securities may be adversely affected, and the value of the Fund’s assets may go down. A public health crisis and the ensuing policies enacted by governments and central banks may cause significant volatility and uncertainty in global financial markets, negatively impacting global growth prospects. As the COVID-19 global pandemic illustrated, such events may affect certain geographic regions, countries, sectors and industries more significantly than others. Advancements in technology may also adversely impact markets and the overall performance of the Fund. For instance, the economy may be significantly impacted by the advanced development and increased regulation of artificial intelligence. Additionally, cyber security breaches of both government and non-government entities could have negative impacts on infrastructure and the ability of such entities, including the Fund, to operate properly. These events, and any other future events, may adversely affect the prices and liquidity of the Fund’s portfolio investments and could result in disruptions in the trading markets.

Roundhill Bitcoin Covered Call Strategy ETF | CYBERSECURITY RISK  
Prospectus [Line Items]  
Risk [Text Block]

CYBERSECURITY RISK. Failures or breaches of the electronic systems of the Fund, the Fund’s adviser, sub-adviser, distributor and other service providers, market makers, Authorized Participants or the issuers of securities in which the Fund invests have the ability to cause disruptions, negatively impact the Fund’s business operations and/or potentially result in financial losses to the Fund and its shareholders. While the Fund has established business continuity plans and risk management systems seeking to address system breaches or failures, there are inherent limitations in such plans and systems. Furthermore, the Fund cannot control the cybersecurity plans and systems of the Fund’s other service providers, market makers, Authorized Participants or issuers of securities in which the Fund invests.

Roundhill Bitcoin Covered Call Strategy ETF | DEBT SECURITIES RISK  
Prospectus [Line Items]  
Risk [Text Block]

DEBT SECURITIES RISK. Investments in debt securities subject the holder to the credit risk of the issuer. Credit risk refers to the possibility that the issuer or other obligor of a security will not be able or willing to make payments of interest and principal when due. Generally, the value of debt securities will change inversely with changes in interest rates. To the extent that interest rates rise, certain underlying obligations may be paid off substantially slower than originally anticipated and the value of those securities may fall sharply. During periods of falling interest rates, the income received by the Fund may decline. If the principal on a debt security is prepaid before expected, the prepayments of principal may have to be reinvested in obligations paying interest at lower rates. Debt securities generally do not trade on a securities exchange making them generally less liquid and more difficult to value than common stock.

Roundhill Bitcoin Covered Call Strategy ETF | DERIVATIVES RISK  
Prospectus [Line Items]  
Risk [Text Block]

DERIVATIVES RISK. The use of derivative instruments involves risks different from, or possibly greater than, the risks associated with investing directly in securities and other traditional investments. These risks include: (i) the risk that the counterparty to a derivative transaction may not fulfill its contractual obligations; (ii) risk of mispricing or improper valuation; and (iii) the risk that changes in the value of the derivative may not correlate perfectly with the underlying asset. Derivative prices are highly volatile and may fluctuate substantially during a short period of time. Such prices are influenced by numerous factors that affect the markets, including, but not limited to: changing supply and demand relationships; government programs and policies; national and international political and economic events, changes in interest rates, inflation and deflation and changes in supply and demand relationships. Trading derivative instruments involves risks different from, or possibly greater than, the risks associated with investing directly in securities. Derivative contracts ordinarily have leverage inherent in their terms. The use of leverage may cause the Fund to liquidate portfolio positions when it would not be advantageous to do so in order to satisfy its obligations or to meet regulatory or contractual requirements for derivatives. The use of derivatives can magnify potential for gain or loss and, therefore, amplify the effects of market volatility on share price.

Roundhill Bitcoin Covered Call Strategy ETF | DISTRIBUTION TAX RISK  
Prospectus [Line Items]  
Risk [Text Block]

DISTRIBUTION TAX RISK. The Fund currently expects to make distributions on a weekly basis. These distributions may exceed the Fund’s income and gains for the Fund’s taxable year. Distributions in excess of the Fund’s current and accumulated earnings and profits will be treated as a return of capital. A return of capital distribution generally will not be taxable but will reduce the shareholder’s cost basis and will result in a higher capital gain or lower capital loss when those Fund Shares on which the distribution was received are sold. Once a Fund shareholder’s cost basis is reduced to zero, further distributions will be treated as capital gain if the Fund shareholder holds Fund Shares as capital assets. Additionally, any capital returned through distributions will be distributed after payment of Fund fees and expenses. Because a portion of the Fund’s distributions may consist of return of capital, the Fund may not be an appropriate investment for investors who do not want their principal investment in the Fund to decrease over time or who do not wish to receive return of capital in a given period. In the event that a shareholder purchases Fund Shares shortly before a distribution by the Fund, the entire distribution may be taxable to the shareholder even though a portion of the distribution effectively represents a return of the purchase price.

Roundhill Bitcoin Covered Call Strategy ETF | ETF RISK  
Prospectus [Line Items]  
Risk [Text Block]

ETF RISK. The value of an ETF held by the Fund will fluctuate over time based on fluctuations in the values of the assets held by the ETF, which may be affected by changes in general economic conditions, expectations for future growth and profits, interest rates and the supply and demand for those assets. When the Fund invests in an ETF, it will bear a proportionate share of the ETF’s expenses. In addition, ETFs are subject to Active Market Risk, Operational Risk, Premium/Discount Risk and the Structural ETF Risks set forth below. Brokerage, tax and other expenses may negatively impact the performance of the ETF and, in turn, the value of Fund Shares.

Roundhill Bitcoin Covered Call Strategy ETF | FLEX OPTIONS RISK  
Prospectus [Line Items]  
Risk [Text Block]

FLEX OPTIONS RISK. Trading FLEX Options involves risks different from, or possibly greater than, the risks associated with investing directly in securities. The Fund may experience losses from specific FLEX Option positions and certain FLEX Option positions may expire worthless. The FLEX Options are listed on an exchange; however, no one can guarantee that a liquid secondary trading market will exist for the FLEX Options. In the event that trading in the FLEX Options is limited or absent, the value of the Fund’s FLEX Options may decrease. In a less liquid market for the FLEX Options, liquidating the FLEX Options may require the payment of a premium (for written FLEX Options) or acceptance of a discounted price (for purchased FLEX Options) and may take longer to complete. A less liquid trading market may adversely impact the value of the FLEX Options and Fund Shares and result in the Fund being unable to achieve its investment objectives. Less liquidity in the trading of the Fund’s FLEX Options could have an impact on the prices paid or received by the Fund for the FLEX Options in connection with creations and redemptions of the Fund’s shares. Depending on the nature of this impact to pricing, the Fund may be forced to pay more for redemptions (or receive less for creations) than the price at which it currently values the FLEX Options. Such overpayment or under collection could reduce the Fund’s ability to achieve its investment objectives. Additionally, in a less liquid market for the FLEX Options, the liquidation of a large number of options may more significantly impact the price. A less liquid trading market may adversely impact the value of the FLEX Options and the value of your investment. The trading in FLEX Options may be less deep and liquid than the market for certain other exchange-traded options, non-customized options or other securities.

Roundhill Bitcoin Covered Call Strategy ETF | INFLATION RISK  
Prospectus [Line Items]  
Risk [Text Block]

INFLATION RISK. Inflation risk is the risk that the value of assets or income from investments will be less in the future as inflation decreases the value of money. As inflation increases, the present value of the Fund’s assets and distributions may decline. This risk is more prevalent with respect to fixed income securities held by the Fund.

Roundhill Bitcoin Covered Call Strategy ETF | Interest Rate Risk [Member]  
Prospectus [Line Items]  
Risk [Text Block]

INTEREST RATE RISK. Interest rate risk is the risk that the value of the debt securities in the Fund’s portfolio will decline because of rising market interest rates. Interest rate risk is generally lower for shorter term debt securities and higher for longer-term debt securities. Duration is a reasonably accurate measure of a debt security’s price sensitivity to changes in interest rates and a common measure of interest rate risk. Duration measures a debt security’s expected life on a present value basis, taking into account the debt security’s yield, interest payments and final maturity. In general, duration represents the expected percentage change in the value of a security for an immediate 1% change in interest rates. For example, the price of a debt security with a three-year duration would be expected to drop by approximately 3% in response to a 1% increase in interest rates. Therefore, prices of debt securities with shorter durations tend to be less sensitive to interest rate changes than debt securities with longer durations. As the value of a debt security changes over time, so will its duration.

Roundhill Bitcoin Covered Call Strategy ETF | LEGISLATION AND LITIGATION RISK  
Prospectus [Line Items]  
Risk [Text Block]

LEGISLATION AND LITIGATION RISK. Legislation or litigation that affects the value of assets or securities held by the Fund may reduce the value of the Fund. From time to time, various legislative initiatives are proposed that may have a negative impact on certain assets or securities in which the Fund invests. In addition, litigation regarding any of the assets or securities owned by the Fund may negatively impact the value of Fund Shares. Such legislation or litigation may cause the Fund to lose value or may result in higher portfolio turnover if the Adviser determines to sell such a holding.

Roundhill Bitcoin Covered Call Strategy ETF | LEVERAGE RISK  
Prospectus [Line Items]  
Risk [Text Block]

LEVERAGE RISK. While the Fund does not seek leveraged exposure to the Bitcoin ETFs, the Fund seeks to achieve and maintain the exposure to the price of the Bitcoin ETFs by using the leverage inherent in options contracts. Therefore, the Fund is subject to leverage risk. When the Fund purchases or sells an instrument or enters into a transaction without investing an amount equal to the full economic exposure of the instrument or transaction, it creates leverage, which can result in the Fund losing more than it originally invested. As a result, these investments may magnify losses to the Fund, and even a small market movement may result in significant losses to the Fund. Leverage may also cause the Fund to be more volatile because it may exaggerate the effect of any increase or decrease in the value of the Fund’s portfolio securities. Options trading involves a degree of leverage and as a result, a relatively small price movement in futures instruments may result in immediate and substantial losses to the Fund.

Roundhill Bitcoin Covered Call Strategy ETF | MONEY MARKET INSTRUMENTS RISK  
Prospectus [Line Items]  
Risk [Text Block]

MONEY MARKET INSTRUMENTS RISK. The value of money market instruments may be affected by changing interest rates and by changes in the credit ratings of the investments. If a significant amount of the Fund’s assets are invested in money market instruments, it will be more difficult for the Fund to achieve its investment objectives. An investment in a money market fund is not insured or guaranteed by the FDIC or any other government agency. It is possible to lose money by investing in a money market fund.

Roundhill Bitcoin Covered Call Strategy ETF | OPERATIONAL RISK  
Prospectus [Line Items]  
Risk [Text Block]

OPERATIONAL RISK. The Fund is subject to risks arising from various operational factors, including, but not limited to, human error, processing and communication errors, errors of the Fund’s service providers, counterparties or other third-parties, failed or inadequate processes and technology or systems failures. The Fund relies on third-parties for a range of services, including custody. Any delay or failure relating to engaging or maintaining such service providers may affect the Fund’s ability to meet its investment objectives. Although the Fund and the Adviser seek to reduce these operational risks through controls and procedures, there is no way to completely protect against such risks.

Roundhill Bitcoin Covered Call Strategy ETF | REVERSE REPURCHASE AGREEMENTS RISK  
Prospectus [Line Items]  
Risk [Text Block]

REVERSE REPURCHASE AGREEMENTS RISK. Reverse repurchase agreements involve both counterparty risk and the risk that the value of securities that the Fund is obligated to repurchase under the agreement may decline below the repurchase price. Reverse repurchase agreements involve leverage risk; the Fund may lose money as a result of declines in the values both of the security subject to the reverse repurchase agreement and the instruments in which the Fund invested the proceeds of the reverse repurchase agreement.

Roundhill Bitcoin Covered Call Strategy ETF | SPECIAL TAX RISK  
Prospectus [Line Items]  
Risk [Text Block]

SPECIAL TAX RISK. The Fund intends to qualify as a “regulated investment company” (“RIC”), however, the federal income tax treatment of certain aspects of the proposed operations of the Fund are not entirely clear. This includes the tax aspects of the Fund’s options strategy, the possible application of the “straddle” rules, and various loss limitation provisions of the Internal Revenue Code of 1986, as amended (the “Code”). If, in any year, the Fund fails to qualify as a RIC under the applicable tax laws, the Fund would be taxed as an ordinary corporation.

 

To the extent that the Fund investments in Bitcoin ETF Options include offsetting positions, the character of gains or losses realized by the Fund under the Code’s “straddle” rules may be affected and may increase the amount of short-term capital gain realized by the Fund. The Fund may hold certain options that do not qualify as “Section 1256 contracts” under Section 1256 of the Code, and disposition of such options will likely result in short-term or long-term capital gains or losses depending on the holding period. In addition, based upon language in the legislative history, the Fund intends to treat the issuer of the options as the issuer of the referenced asset or in the case of Bitcoin ETF Options that reference a Bitcoin ETF Index, the issuers of the securities underlying the index, which, assuming the referenced asset qualifies as a RIC, would allow the Fund to qualify for special rules in the RIC diversification requirements. If the income is not qualifying income or the issuer of the options is not appropriately the referenced asset or the issuers of the securities underlying the index, the Fund could lose its own status as a RIC.

 

The Fund intends to treat the income it derives from gains on options referencing the Bitcoin ETFs and Bitcoin ETF Indexes as “qualifying income” for purposes of the RIC qualification rules under Subchapter M of the Code. It has adopted this position in reliance on an opinion obtained from counsel that income from such investments should constitute “qualifying income,” as the Bitcoin ETFs and Bitcoin ETF Indexes referenced by the options constitute “securities” under Section 2(a)(36) of the 1940 Act. However, this opinion is not binding upon the Internal Revenue Service (“IRS”). If the IRS were to successfully assert that the Fund’s income from such investments was not “qualifying income,” the Fund may fail to qualify as a RIC under Subchapter M if over 10% of its gross income was derived from these investments. If the Fund failed to qualify as a RIC, it would be subject to federal and state income tax on all of its taxable income at regular corporate tax rates with no deduction for any distributions paid to shareholders, which would significantly adversely affect the returns to, and could cause substantial losses for, Fund shareholders.

 

To maintain its status as a RIC, the Fund must distribute 90% of its investment company taxable income annually. In addition, to avoid a non-deductible excise tax, the Fund must distribute 98% of its ordinary income and 98.2% of its capital gain net income. Separately, depending upon the circumstances, sales to fund redemptions could cause the Fund to recognize income that the Fund is required to distribute to maintain the Fund’s RIC status and avoid the excise tax. Funding such distributions could require additional sales, which could require more distributions and affect the projected performance of the Fund. Alternatively, if the Fund only makes distributions to maintain its RIC status and becomes subject to the excise tax, that could also affect the projected performance of the Fund. In either case, the assets sold to fund redemptions, distributions or pay the excise tax will not be available to assist the Fund in meeting its investment objectives.

 

In the event that a shareholder purchases shares of the Fund shortly before a distribution by the Fund, the entire distribution may be taxable to the shareholder even though a portion of the distribution effectively represents a return of the purchase price.

Roundhill Bitcoin Covered Call Strategy ETF | STRUCTURAL ETF RISKS  
Prospectus [Line Items]  
Risk [Text Block]

STRUCTURAL ETF RISKS. The Fund is an ETF. Accordingly, it is subject to certain risks associated with its unique structure.

 

Cash Transactions Risk. The Fund currently expects to effect a significant portion of its creations and redemptions for cash, rather than in-kind securities. Paying redemption proceeds in cash rather than through in-kind delivery of portfolio securities may require the Fund to dispose of or sell portfolio securities or other assets at an inopportune time to obtain the cash needed to meet redemption orders. This may cause the Fund to sell a security and recognize a capital gain or loss that might not have been incurred if it had made a redemption in-kind. As a result, the Fund may pay out higher or lower annual capital gains distributions than ETFs that redeem in-kind. The use of cash creations and redemptions may also cause the Fund’s Shares to trade in the market at greater bid-ask spreads or greater premiums or discounts to the Fund’s NAV. Furthermore, the Fund may not be able to execute cash transactions for creation and redemption purposes at the same price used to determine the Fund’s NAV. To the extent that the maximum additional charge for creation or redemption transactions is insufficient to cover the execution shortfall, the Fund’s performance could be negatively impacted.

 

Market Participants Risk. Only an Authorized Participant may engage in creation or redemption transactions directly with the Fund, and none of those Authorized Participants is obligated to engage in creation and/or redemption transactions. The Fund has a limited number of institutions that may act as Authorized Participants on an agency basis (i.e., on behalf of other market participants). To the extent that Authorized Participants exit the business or are unable to proceed with creation or redemption orders with respect to the Fund and no other Authorized Participant is able to step forward to create or redeem, Fund Shares may be more likely to trade at a premium or discount to NAV and possibly face trading halts or delisting. The Fund may also rely on a small number of third-party market makers to provide a market for the purchase and sale of Fund Shares but such market makers are under no obligation to do so. Decisions by Authorized Participants or market makers to reduce their role or step away from these activities in times of market stress could inhibit the effectiveness of the arbitrage process in maintaining the relationship between the underlying values of the Fund’s portfolio securities and the Fund’s market price. Any trading halt or other problem relating to the trading activity of these market makers or any issues disrupting the Authorized Participants’ ability to proceed with creation and/or redemption orders could result in a dramatic change in the spread between the Fund’s net asset value and the price at which Fund Shares are trading on the Exchange, which could result in a decrease in value of Fund Shares. This reduced effectiveness could result in Fund Shares trading at a premium or discount to net asset value and also in greater than normal intraday bid-ask spreads Fund Shares.

 

Costs of Buying and Selling Fund Shares. Due to the costs of buying or selling Fund Shares, including brokerage commissions imposed by brokers and bid/ask spreads, frequent trading of Fund Shares may significantly reduce investment results and an investment in Fund Shares may not be advisable for investors who anticipate regularly making small investments.

 

Premium/Discount Risk. As with all ETFs, Fund Shares may be bought and sold in the secondary market at market prices. The trading prices of Fund Shares in the secondary market may differ from the Fund’s daily net asset value per share and there may be times when the market price of Fund Shares is more than the net asset value per Fund Share (premium) or less than the net asset value per Fund Share (discount). If a shareholder purchases Fund Shares at a time when the market price is at a premium to the net asset value or sells Fund Shares at a time when the market price is at a discount to the net asset value, the shareholder may pay more for, or receive less than, the underlying value of the Fund Shares, respectively. This risk is heightened in times of market volatility or periods of steep market declines.

 

Trading Risks. Although Fund Shares are listed for trading on the Exchange and may be traded on U.S. exchanges other than the Exchange, there can be no assurance that Fund Shares will trade with any volume, or at all, on any stock exchange. In stressed market conditions, the liquidity of Fund Shares may begin to mirror the liquidity of the Fund’s underlying portfolio holdings, which can be significantly less liquid than Fund Shares. Trading in Fund Shares on the Exchange may be halted due to market conditions or for reasons that, in the view of the Exchange, make trading in Fund Shares inadvisable. In addition, trading in Fund Shares on the Exchange is subject to trading halts caused by extraordinary market volatility pursuant to the Exchange’s “circuit breaker” rules. There can be no assurance that the requirements of the Exchange necessary to maintain the listing of the Fund will continue to be met or will remain unchanged.

Risk [Text Block]

U.S. GOVERNMENT SECURITIES RISK. U.S. government securities are subject to interest rate risk but generally do not involve the credit risks associated with investments in other types of debt securities. As a result, the yields available from U.S. government securities are generally lower than the yields available from other debt securities. U.S. government securities are guaranteed only as to the timely payment of interest and the payment of principal when held to maturity.

Roundhill Bitcoin Covered Call Strategy ETF | VALUATION RISK  
Prospectus [Line Items]  
Risk [Text Block]

VALUATION RISK. The Fund may hold securities or other assets that may be valued on the basis of factors other than market quotations. This may occur because the asset or security does not trade on a centralized exchange, or in times of market turmoil or reduced liquidity. There are multiple methods that can be used to value a portfolio holding when market quotations are not readily available. The value established for any portfolio holding at a point in time might differ from what would be produced using a different methodology or if it had been priced using market quotations. Portfolio holdings that are valued using techniques other than market quotations, including “fair valued” assets or securities, may be subject to greater fluctuation in their valuations from one day to the next than if market quotations were used. In addition, there is no assurance that the Fund or a Bitcoin ETF could sell or close out a portfolio position for the value established for it at any time, and it is possible that the Fund or a Bitcoin ETF would incur a loss because a portfolio position is sold or closed out at a discount to the valuation established by the Fund or a Bitcoin ETF at that time. The Fund’s or a Bitcoin ETF’s ability to value investments may be impacted by technological issues or errors by pricing services or other third-party service providers.

NON-DIVERSIFICATION RISK. As a “non-diversified” fund, the Fund may hold a smaller number of portfolio securities than many other funds. To the extent the Fund invests in a relatively small number of issuers, a decline in the market value of a particular security held by the Fund may affect its value more than if it invested in a larger number of issuers. The value of the Fund Shares may be more volatile than the values of shares of more diversified funds.

Roundhill China Magnificent Seven ETF | MARKET RISK  
Prospectus [Line Items]  
Risk [Text Block]

MARKET RISK. Market risk is the risk that a particular investment, or Fund Shares in general, may fall in value. Securities are subject to market fluctuations caused by real or perceived adverse economic, political, and regulatory factors or market developments, changes in interest rates, disruptions to trade, impositions of tariffs and perceived trends in securities prices. Fund Shares could decline in value or underperform other investments. In addition, local, regional or global events such as war, acts of terrorism, market manipulation, government defaults, government shutdowns, regulatory actions, political changes, diplomatic developments, the imposition of sanctions and other similar measures, spread of infectious diseases or other public health issues, recessions, natural disasters, or other events could have a significant negative impact on the Fund and its investments. Any of such circumstances could have a materially negative impact on the value of Fund Shares, the liquidity of an investment, and may result in increased market volatility. During any such events, Fund Shares may trade at increased premiums or discounts to their net asset value, the bid/ask spread on Fund Shares may widen and the returns on investment may fluctuate.

Roundhill China Magnificent Seven ETF | LIQUIDITY RISK  
Prospectus [Line Items]  
Risk [Text Block]

LIQUIDITY RISK. The Fund’s swap agreements and/or forward contracts trade over-the-counter, in limited volume and generally lack an active trading market. Accordingly, the Fund may not be able to sell or close out of such investments at favorable times or prices (or at all), or at the prices approximating those at which the Fund currently values them. Illiquid securities may trade at a discount from comparable, more liquid investments and may be subject to wide fluctuations in market value.

Roundhill China Magnificent Seven ETF | ACTIVE MANAGEMENT RISK

ACTIVE MANAGEMENT RISK. The Fund is actively-managed and its performance reflects investment decisions that the Adviser and/or Sub-Adviser makes for the Fund. Such judgments about the Fund’s investments may prove to be incorrect. If the investments selected and the strategies employed by the Fund fail to produce the intended results, the Fund could underperform as compared to other funds with similar investment objectives and/or strategies, or could have negative returns.

CONCENTRATION RISK. The Fund is concentrated in the industry or group of industries comprising the consumer discretionary sector and communication services sector. The Fund may be susceptible to an increased risk of loss, including losses due to adverse events that affect the Fund’s investments more than the market as a whole, to the extent that the Fund’s investments are concentrated in the securities and/or other assets of a particular issuer or issuers, country, group of countries, region, market, industry, group of industries, sector, market segment or asset class.

Roundhill China Magnificent Seven ETF | COUNTERPARTY RISK  
Prospectus [Line Items]  
Risk [Text Block]

COUNTERPARTY RISK. Any swap agreements and/or forward contracts utilized by the Fund will be subject to counterparty risk. Fund transactions involving a counterparty are subject to the risk that the counterparty will not fulfill its obligation to the Fund. Counterparty risk may arise because of the counterparty’s financial condition (i.e., financial difficulties, bankruptcy, or insolvency), market activities and developments, or other reasons, whether foreseen or not. A counterparty’s inability to fulfill its obligation may result in significant financial loss to the Fund. The Fund may be unable to recover its investment from the counterparty or may obtain a limited recovery, and/or recovery may be delayed.

Roundhill China Magnificent Seven ETF | CURRENT MARKET CONDITIONS RISK  
Prospectus [Line Items]  
Risk [Text Block]

CURRENT MARKET CONDITIONS RISK. Current market conditions risk is the risk that a particular investment, or Fund Shares in general, may fall in value due to current market conditions. As a means to fight inflation, which remains at elevated levels, the Federal Reserve and certain foreign central banks have raised interest rates; however, the Federal Reserve has recently lowered interest rates and may continue to do so. U.S. regulators have proposed several changes to market and issuer regulations which would directly impact the Fund, and any regulatory changes could adversely impact the Fund’s ability to achieve its investment strategies or make certain investments. Recent and potential future bank failures could result in disruption to the broader banking industry or markets generally and reduce confidence in financial institutions and the economy as a whole, which may also heighten market volatility and reduce liquidity. Additionally, challenges in commercial real estate markets, including rising interest rates, declining valuations and increasing vacancies, could have a broader impact on financial markets. The ongoing adversarial political climate in the United States, as well as political and diplomatic events both domestic and abroad, have and may continue to have an adverse impact the U.S. regulatory landscape, markets and investor behavior, which could have a negative impact on the Fund’s investments and operations. The change in administration resulting from the 2024 United States national elections could result in significant impacts to international trade relations, tax and immigration policies, and other aspects of the national and international political and financial landscape, which could affect, among other things, inflation and the securities markets generally. Other unexpected political, regulatory and diplomatic events within the U.S. and abroad may affect investor and consumer confidence and may adversely impact financial markets and the broader economy. For example, ongoing armed conflicts between Russia and Ukraine in Europe and among Israel, Iran, Hamas and other militant groups in the Middle East, have caused and could continue to cause significant market disruptions and volatility within the markets in Russia, Europe, the Middle East and the United States. The hostilities and sanctions resulting from those hostilities have and could continue to have a significant impact on certain Fund investments as well as Fund performance and liquidity. The economies of the United States and its trading partners, as well as the financial markets generally, may be adversely impacted by trade disputes, including the imposition of tariffs, and other matters. For example, the United States has imposed trade barriers and restrictions on China. In addition, the Chinese government is engaged in a longstanding dispute with Taiwan, continually threatening an invasion. If the political climate between the United States and China does not improve or continues to deteriorate, if China were to attempt invading Taiwan, or if other geopolitical conflicts develop or worsen, economies, markets and individual securities may be adversely affected, and the value of the Fund’s assets may go down. A public health crisis and the ensuing policies enacted by governments and central banks may cause significant volatility and uncertainty in global financial markets, negatively impacting global growth prospects. As the COVID-19 global pandemic illustrated, such events may affect certain geographic regions, countries, sectors and industries more significantly than others. Advancements in technology may also adversely impact markets and the overall performance of the Fund. For instance, the economy may be significantly impacted by the advanced development and increased regulation of artificial intelligence. Additionally, cyber security breaches of both government and non-government entities could have negative impacts on infrastructure and the ability of such entities, including the Fund, to operate properly. These events, and any other future events, may adversely affect the prices and liquidity of the Fund’s portfolio investments and could result in disruptions in the trading markets.

Roundhill China Magnificent Seven ETF | CYBERSECURITY RISK

Risk [Text Block]

CYBERSECURITY RISK. Failures or breaches of the electronic systems of the Fund, the Fund’s adviser, sub-adviser distributor, and other service providers, market makers, Authorized Participants or the issuers of securities in which the Fund invests have the ability to cause disruptions, negatively impact the Fund’s business operations and/or potentially result in financial losses to the Fund and its shareholders. While the Fund has established business continuity plans and risk management systems seeking to address system breaches or failures, there are inherent limitations in such plans and systems. Furthermore, the Fund cannot control the cybersecurity plans and systems of the Fund’s other service providers, market makers, Authorized Participants or issuers of securities in which the Fund invests.

Roundhill China Magnificent Seven ETF | DERIVATIVES RISK  
Prospectus [Line Items]  
Risk [Text Block]

DERIVATIVES RISK. The use of derivative instruments (i.e. swap agreements and forward contracts) involves risks different from, or possibly greater than, the risks associated with investing directly in securities and other traditional investments. These risks include: (i) the risk that the counterparty to a derivative transaction may not fulfill its contractual obligations; (ii) risk of mispricing or improper valuation; and (iii) the risk that changes in the value of the derivative may not correlate perfectly with the underlying asset. Derivative prices are highly volatile and may fluctuate substantially during a short period of time. Such prices are influenced by numerous factors that affect the markets, including, but not limited to: changing supply and demand relationships; government programs and policies; national and international political and economic events, changes in interest rates, inflation and deflation and changes in supply and demand relationships. Trading derivative instruments involves risks different from, or possibly greater than, the risks associated with investing directly in securities. Derivative contracts ordinarily have leverage inherent in their terms. The use of leverage may cause the Fund to liquidate portfolio positions when it would not be advantageous to do so in order to satisfy its obligations or to meet regulatory or contractual requirements for derivatives. The use of derivatives can magnify potential for gain or loss and, therefore, amplify the effects of market volatility on the Fund Share price.

Roundhill China Magnificent Seven ETF | INFLATION RISK

Risk [Text Block]

INFLATION RISK. Inflation risk is the risk that the value of assets or income from investments will be less in the future as inflation decreases the value of money. As inflation increases, the present value of the Fund’s assets and distributions may decline. This risk is considered to be heightened as it relates to Chinese companies.

Roundhill China Magnificent Seven ETF | OPERATIONAL RISK

OPERATIONAL RISK. The Fund is subject to risks arising from various operational factors, including, but not limited to, human error, processing and communication errors, errors of the Fund’s service providers, counterparties or other third-parties, failed or inadequate processes and technology or systems failures. The Fund relies on third-parties for a range of services, including custody. Any delay or failure relating to engaging or maintaining such service providers may affect the Fund’s ability to meet its investment objective. Although the Fund and the Adviser seek to reduce these operational risks through controls and procedures, there is no way to completely protect against such risks.

As a result, the yields available from U.S. government securities are generally lower than the yields available from other debt securities.

Roundhill China Magnificent Seven ETF | CHINA RISK  
Prospectus [Line Items]  
Risk [Text Block]

CHINA RISK. The Fund’s significant investments in instruments that provide exposure to Chinese companies subject the Fund to risks specific to China. China may be subject to considerable degrees of economic, political and social instability. China is an emerging market and demonstrates significantly higher volatility from time to time in comparison to developed markets. Over the last few decades, the Chinese government has undertaken reform of economic and market practices and has expanded the sphere of private ownership of property in China. However, Chinese markets generally continue to experience inefficiency, volatility and pricing anomalies resulting from governmental influence, a lack of publicly available information and/or political and social instability.

 

Chinese companies are also subject to the risk that Chinese authorities can intervene in their operations and structure. Internal social unrest or confrontations with neighboring countries, including military conflicts in response to such events, may also disrupt economic development in China and result in a greater risk of currency fluctuations, currency non-convertibility, interest rate fluctuations and higher rates of inflation.

 

China has experienced security concerns, such as terrorism and strained international relations. Additionally, China is alleged to have participated in state-sponsored cyberattacks against foreign companies and foreign governments. Actual and threatened responses to such activity and strained international relations, including purchasing restrictions, sanctions, tariffs or cyberattacks on the Chinese government or Chinese companies, may impact China’s economy and Chinese issuers of securities in which the Fund invests. Incidents involving China’s or the region’s security may cause uncertainty in Chinese markets and may adversely affect the Chinese economy and the Fund’s investments. Export growth continues to be a major driver of China’s rapid economic growth. Reduction in spending on Chinese products and services, supply chain diversification, institution of additional tariffs or other trade barriers (including as a result of heightened trade tensions or a trade war between China and the U.S. or in response to actual or alleged Chinese cyber activity) or a downturn in any of the economies of China’s key trading partners may have an adverse impact on the Chinese economy. The Fund’s portfolio may include companies that are subject to economic or trade restrictions (but not investment restrictions) imposed by the U.S. or other governments due to national security, human rights or other concerns of such government. So long as these restrictions do not include restrictions on investments, the Fund is generally expected to invest in such companies.

 

Chinese companies are not subject to the same degree of regulatory requirements, accounting standards or auditor oversight as companies in more developed countries. As a result, information about the Chinese securities in which the Fund invests may be less reliable or complete. Chinese companies with securities listed on U.S. exchanges may be delisted if they do not meet U.S. accounting standards and auditor oversight requirements, which would significantly decrease the liquidity and value of the securities. There may be significant obstacles to obtaining information necessary for investigations into or litigation against Chinese companies, and shareholders may have limited legal remedies. Chinese companies may also be subject to significantly weaker recordkeeping requirements than the requirements imposed upon U.S. companies.

Roundhill China Magnificent Seven ETF | COMMUNICATION SERVICES SECTOR RISK  
Prospectus [Line Items]  
Risk [Text Block]

COMMUNICATION SERVICES SECTOR RISK. Communication services companies may be subject to specific risks associated with legislative or regulatory changes, adverse market conditions, intellectual property use and/or increased competition. Communication services companies are particularly vulnerable to rapid advancements in technology, the innovation of competitors, rapid product obsolescence and government regulation and competition, both domestically and internationally. Additionally, fluctuating domestic and international demand, shifting demographics and often unpredictable changes in consumer tastes can drastically affect a communication services company’s profitability. While all companies may be susceptible to network security breaches, certain communication services companies may be particular targets of hacking and potential theft of proprietary or consumer information or disruptions in service, which could have a material adverse effect on their businesses.

Roundhill China Magnificent Seven ETF | CONSUMER DISCRETIONARY SECTOR RISK  
Prospectus [Line Items]  
Risk [Text Block]

CONSUMER DISCRETIONARY SECTOR RISK. Consumer discretionary companies, such as retailers, media companies and consumer services companies, provide non-essential goods and services. These companies manufacture products and provide discretionary services directly to the consumer, and the success of these companies is tied closely to the performance of the overall domestic and international economy, interest rates, competition and consumer confidence. Success depends heavily on disposable household income and consumer spending. Changes in demographics and consumer tastes can also affect the demand for, and success of, consumer discretionary products in the marketplace.

Roundhill China Magnificent Seven ETF | CURRENCY RISK  
Prospectus [Line Items]

CURRENCY RISK. Changes in currency exchange rates affect the value of investments denominated in a foreign currency, and therefore the value of such investments in the Fund’s portfolio. The Fund’s net asset value could decline if a currency to which the Fund has exposure depreciates against the U.S. dollar or if there are delays or limits on repatriation of such currency. Currency exchange rates can be very volatile and can change quickly and unpredictably. As a result, the value of an investment in the Fund may change quickly and without warning.

Roundhill China Magnificent Seven ETF | CUSTODY RISK

CUSTODY RISK. Custody risk refers to the risks inherent in the process of clearing and settling trades, as well as the holding of securities by local banks, agents and depositories. Low trading volumes and volatile prices in less developed markets may make trades harder to complete and settle, and governments or trade groups may compel local agents to hold securities in designated depositories that may not be subject to independent evaluation. Local agents are held only to the standards of care of their local markets. In general, the less developed a country’s securities markets are, the higher the degree of custody risk.

Roundhill China Magnificent Seven ETF | DEPOSITARY RECEIPTS RISK

DEPOSITARY RECEIPTS RISK. Depositary receipts may be less liquid than the underlying shares in their primary trading market. Any distributions paid to the holders of depositary receipts are usually subject to a fee charged by the depositary. Holders of depositary receipts may have limited voting rights, and investment restrictions in certain countries may adversely impact the value of depositary receipts because such restrictions may limit the ability to convert the equity shares into depositary receipts and vice versa. Such restrictions may cause the equity shares of the underlying issuer to trade at a discount or premium to the market price of the depositary receipts.

EMERGING MARKETS RISK. The Fund’s investments in China may be subject to a greater risk of loss than investments in more developed markets. Emerging markets may be more likely to experience inflation, political turmoil and rapid changes in economic conditions than more developed markets. Emerging markets often have less uniformity in accounting and reporting requirements, unreliable securities valuation and greater risk associated with custody of securities.

Roundhill China Magnificent Seven ETF | EQUITY SECURITIES RISK  
Prospectus [Line Items]  
Risk [Text Block]

EQUITY SECURITIES RISK. Equity securities are subject to changes in value, and their values may be more volatile than those of other asset classes. Equity securities prices fluctuate for several reasons, including changes in investors’ perceptions of the financial condition of an issuer or the general condition of the relevant equity market, such as market volatility, or when political or economic events affecting an issuer occur. Common stock prices may be particularly sensitive to rising interest rates, as the cost of capital rises and borrowing costs increase. Common stocks generally subject their holders to more risks than preferred stocks and debt securities because common stockholders’ claims are subordinated to those of holders of preferred stocks and debt securities upon the bankruptcy of the issuer.

Roundhill China Magnificent Seven ETF | FORWARD CONTRACTS RISK  
Prospectus [Line Items]  
Risk [Text Block]

FORWARD CONTRACTS RISK. The Fund may utilize forward contracts to derive its exposure to one or more of the Chinese Magnificent Seven. A forward contract is an over-the-counter derivative transaction between two parties to buy or sell a specified amount of an underlying reference at a specified price (or rate) on a specified date in the future. Forward contracts are negotiated on an individual basis and are not standardized or traded on exchanges. The market for forward contracts is substantially unregulated and can experience lengthy periods of illiquidity, unusually high trading volume and other negative impacts, such as political intervention, which may result in volatility or disruptions in such markets. A relatively small price movement in a forward contract may result in substantial losses to the Fund, exceeding the amount of the margin paid.

Roundhill China Magnificent Seven ETF | HONG KONG RISK

Risk [Text Block]

HONG KONG RISK. Investments in Hong Kong issuers will subject the Fund to legal, regulatory, political, currency, security, and economic risk specific to Hong Kong. China is Hong Kong’s largest trading partner, both in terms of exports and imports. Any changes in the Chinese economy, trade regulations or currency exchange rates, or a tightening of China’s control over Hong Kong, may have an adverse impact on Hong Kong’s economy. Additionally, Hong Kong is a small island state with few raw material resources and limited land area and is reliant on imports for its commodity needs. Any fluctuations or shortages in the commodity markets could have a negative impact on the Hong Kong economy.

Risk [Text Block]

INFORMATION TECHNOLOGY COMPANIES RISK. Information technology companies face intense competition, both domestically and internationally, which may have an adverse effect on profit margins. Like other technology companies, information technology companies may have limited product lines, markets, financial resources or personnel. The products of information technology companies may face obsolescence due to rapid technological developments, frequent new product introduction, unpredictable changes in growth rates and competition for the services of qualified personnel. Companies in the information technology sector are heavily dependent on patent and intellectual property rights. The loss or impairment of these rights may adversely affect the profitability of these companies. Information technology companies are facing increased government and regulatory scrutiny and may be subject to adverse government or regulatory action.

Roundhill China Magnificent Seven ETF | INTERNATIONAL CLOSED MARKET TRADING RISK  
Prospectus [Line Items]  
Risk [Text Block]

INTERNATIONAL CLOSED MARKET TRADING RISK. To the extent securities held by the Fund trade on non-U.S. exchanges that are closed when the Fund’s primary listing exchange is open, there are likely to be deviations between the current price of an underlying security and the last quoted price for the underlying security (i.e., the Fund’s quote from the closed foreign market) used for purposes of calculating the Fund’s NAV, resulting in premiums or discounts to the Fund’s NAV and bid/ask spreads that may be greater than those experienced by other funds. In addition, shareholders may not be able to purchase and sell shares of the Fund on days when the NAV of the Fund could be significantly affected by events in the relevant foreign markets.

Roundhill China Magnificent Seven ETF | ISSUER RISK  
Prospectus [Line Items]  
Risk [Text Block]

ISSUER RISK. The performance of the Fund depends on the performance of individual securities to which the Fund has exposure. Changes in the financial condition or credit rating of an issuer of those securities may cause the value of the securities to decline. There is no guarantee that an issuer that paid dividends in the past will continue to do so in the future or will continue paying dividends at the same level.

Roundhill China Magnificent Seven ETF | LARGE CAPITALIZATION COMPANIES RISK

LARGE CAPITALIZATION COMPANIES RISK. Large capitalization companies may be less able than smaller capitalization companies to adapt to changing market conditions. Large capitalization companies may be more mature and subject to more limited growth potential compared with smaller capitalization companies. During different market cycles, the performance of large capitalization companies has trailed the overall performance of the broader securities markets.

Roundhill China Magnificent Seven ETF | MONEY MARKET FUNDS RISK  
Prospectus [Line Items]  
Risk [Text Block]

MONEY MARKET FUNDS RISK. The Fund may invest in money market funds to collateralize its swap agreements and forwards contracts. An investment in a money market fund is not a bank deposit and is not insured or guaranteed by any bank, the Federal Deposit Insurance Corporation (“FDIC”) or any other government agency. Although money market funds seek to preserve the value of investments at $1.00 per share, it is possible for the Fund to lose money if shares of money market funds in which it invests fall below $1.00 per share.

Roundhill China Magnificent Seven ETF | NON-U.S. SECURITIES RISK  
Prospectus [Line Items]  
Risk [Text Block]

NON-U.S. SECURITIES RISK. Non-U.S. securities are subject to higher volatility than securities of domestic issuers due to possible adverse political, social or economic developments, restrictions on foreign investment or exchange of securities, capital controls, lack of liquidity, currency exchange rates, excessive taxation, government seizure of assets, the imposition of sanctions by foreign governments, different legal or accounting standards, and less government supervision and regulation of securities exchanges in foreign countries.

Roundhill China Magnificent Seven ETF | PRIVATIZATION RISK  
Prospectus [Line Items]  
Risk [Text Block]

PRIVATIZATION RISK. China has privatized, or has begun a process of privatizing, certain entities and industries. Newly privatized companies may face strong competition from government-sponsored competitors that have not been privatized. In some instances, investors in newly privatized entities have suffered losses due to the inability of the newly privatized entities to adjust quickly to a competitive environment or changing regulatory and legal standards or, in some cases, due to re-nationalization of such privatized entities. There is no assurance that similar losses will not recur.

Roundhill China Magnificent Seven ETF | SWAP AGREEMENTS RISK  
Prospectus [Line Items]  
Risk [Text Block]

SWAP AGREEMENTS RISK. The Fund may utilize swap agreements to derive its exposure to one or more of the Chinese Magnificent Seven. Swap agreements may involve greater risks than direct investment in securities as they may be leveraged and are subject to credit risk, counterparty risk and valuation risk. A swap agreement could result in losses if the underlying reference or asset does not perform as anticipated. In addition, many swaps trade over-the-counter and may be considered illiquid. It may not be possible for the Fund to liquidate a swap position at an advantageous time or price, which may result in significant losses.

Roundhill China Magnificent Seven ETF | VARIABLE INTEREST RISK  
Prospectus [Line Items]  
Risk [Text Block]

VARIABLE INTEREST RISK. Exposure to VIEs may pose additional risks because the investment is made in reference to an intermediary shell company that has entered into service and other contracts with the underlying Chinese operating company to provide investors with exposure to the operating company, but does not represent equity ownership in the operating company. As a result, such investment may limit the rights of an investor with respect to the underlying Chinese operating company. VIEs allow foreign shareholders to exert a degree of control over, and obtain economic benefits arising from, the operating company without formal legal ownership. However, the contractual arrangements between the shell company and the operating company may not be as effective in providing operational control as direct equity ownership, and a foreign investor's rights may be limited by, for example, actions of the Chinese government which could determine that the underlying contractual arrangements on which control of the VIE is based are invalid. The contractual arrangement on which the VIE structure is based would likely be subject to Chinese law and jurisdiction, which could raise questions about how recourse is sought. Investments through VIEs may be affected by conflicts of interest and duties between the legal owners of the VIE and the stockholders of the listed holding company, which could adversely impact the value of investments. VIEs are not formally recognized under Chinese law and investors face uncertainty about future actions by the Chinese government that could significantly affect the operating company's financial performance and the enforceability of the contractual arrangements underlying the VIE structure. Prohibitions of these structures by the Chinese government, or the inability to enforce such contracts, from which the shell company derives its value, would likely cause the VIE-structured holding(s) to suffer significant losses, and in turn, adversely affect the Fund's returns and net asset value.

Risk [Text Block]

NON-DIVERSIFICATION RISK. As a “non-diversified” fund, the Fund may hold a smaller number of portfolio securities than many other funds. To the extent the Fund invests in a relatively small number of issuers, a decline in the market value of a particular security held by the Fund may affect its value more than if it invested in a larger number of issuers. The value of the Fund Shares may be more volatile than the values of shares of more diversified funds.

Roundhill Meme Stock ETF | MARKET RISK  
Prospectus [Line Items]  
Risk [Text Block]

MARKET RISK. Market risk is the risk that a particular investment, or Fund Shares in general, may fall in value. Securities are subject to market fluctuations caused by real or perceived adverse economic, political, and regulatory factors or market developments, changes in interest rates, disruptions to trade, impositions of tariffs and perceived trends in securities prices. Fund Shares could decline in value or underperform other investments. In addition, local, regional or global events such as war, acts of terrorism, market manipulation, government defaults, government shutdowns, regulatory actions, political changes, diplomatic developments, the imposition of sanctions and other similar measures, spread of infectious diseases or other public health issues, recessions, natural disasters, or other events could have a significant negative impact on the Fund and its investments. Any of such circumstances could have a materially negative impact on the value of Fund Shares, the liquidity of an investment, and may result in increased market volatility. During any such events, Fund Shares may trade at increased premiums or discounts to their net asset value, the bid/ask spread on Fund Shares may widen and the returns on investment may fluctuate.

Roundhill Meme Stock ETF | ACTIVE MANAGEMENT RISK  
Prospectus [Line Items]

ACTIVE MANAGEMENT RISK. The Fund is actively-managed and its performance reflects investment decisions that the Adviser and/or Sub-Adviser makes for the Fund. Such judgments about the Fund’s investments may prove to be incorrect. If the investments selected and the strategies employed by the Fund fail to produce the intended results, the Fund could underperform as compared to other funds with similar investment objectives and/or strategies, or could have negative returns.

Roundhill Meme Stock ETF | CURRENT MARKET CONDITIONS RISK  
Prospectus [Line Items]  
Risk [Text Block]

CURRENT MARKET CONDITIONS RISK. Current market conditions risk is the risk that a particular investment, or Fund Shares in general, may fall in value due to current market conditions. As a means to fight inflation, which remains at elevated levels, the Federal Reserve and certain foreign central banks have raised interest rates; however, the Federal Reserve has recently lowered interest rates and may continue to do so. U.S. regulators have proposed several changes to market and issuer regulations which would directly impact the Fund, and any regulatory changes could adversely impact the Fund’s ability to achieve its investment strategies or make certain investments. Recent and potential future bank failures could result in disruption to the broader banking industry or markets generally and reduce confidence in financial institutions and the economy as a whole, which may also heighten market volatility and reduce liquidity. Additionally, challenges in commercial real estate markets, including rising interest rates, declining valuations and increasing vacancies, could have a broader impact on financial markets. The ongoing adversarial political climate in the United States, as well as political and diplomatic events both domestic and abroad, have and may continue to have an adverse impact the U.S. regulatory landscape, markets and investor behavior, which could have a negative impact on the Fund’s investments and operations. The change in administration resulting from the 2024 United States national elections could result in significant impacts to international trade relations, tax and immigration policies, and other aspects of the national and international political and financial landscape, which could affect, among other things, inflation and the securities markets generally. Other unexpected political, regulatory and diplomatic events within the U.S. and abroad may affect investor and consumer confidence and may adversely impact financial markets and the broader economy. For example, ongoing armed conflicts between Russia and Ukraine in Europe and among Israel, Iran, Hamas and other militant groups in the Middle East, have caused and could continue to cause significant market disruptions and volatility within the markets in Russia, Europe, the Middle East and the United States. The hostilities and sanctions resulting from those hostilities have and could continue to have a significant impact on certain Fund investments as well as Fund performance and liquidity. The economies of the United States and its trading partners, as well as the financial markets generally, may be adversely impacted by trade disputes, including the imposition of tariffs, and other matters. For example, the United States has imposed trade barriers and restrictions on China. In addition, the Chinese government is engaged in a longstanding dispute with Taiwan, continually threatening an invasion. If the political climate between the United States and China does not improve or continues to deteriorate, if China were to attempt invading Taiwan, or if other geopolitical conflicts develop or worsen, economies, markets and individual securities may be adversely affected, and the value of the Fund’s assets may go down. A public health crisis and the ensuing policies enacted by governments and central banks may cause significant volatility and uncertainty in global financial markets, negatively impacting global growth prospects. As the COVID-19 global pandemic illustrated, such events may affect certain geographic regions, countries, sectors and industries more significantly than others. Advancements in technology may also adversely impact markets and the overall performance of the Fund. For instance, the economy may be significantly impacted by the advanced development and increased regulation of artificial intelligence. Additionally, cyber security breaches of both government and non-government entities could have negative impacts on infrastructure and the ability of such entities, including the Fund, to operate properly. These events, and any other future events, may adversely affect the prices and liquidity of the Fund’s portfolio investments and could result in disruptions in the trading markets.

Roundhill Meme Stock ETF | CYBERSECURITY RISK  
Prospectus [Line Items]  
Risk [Text Block]

CYBERSECURITY RISK. Failures or breaches of the electronic systems of the Fund, the Fund’s adviser, sub-adviser, distributor, and other service providers, market makers, Authorized Participants or the issuers of securities in which the Fund invests have the ability to cause disruptions, negatively impact the Fund’s business operations and/or potentially result in financial losses to the Fund and its shareholders. While the Fund has established business continuity plans and risk management systems seeking to address system breaches or failures, there are inherent limitations in such plans and systems. Furthermore, the Fund cannot control the cybersecurity plans and systems of the Fund’s other service providers, market makers, Authorized Participants or issuers of securities in which the Fund invests.

Roundhill Meme Stock ETF | OPERATIONAL RISK  
Prospectus [Line Items]  
Risk [Text Block]

OPERATIONAL RISK. The Fund is subject to risks arising from various operational factors, including, but not limited to, human error, processing and communication errors, errors of the Fund’s service providers, counterparties or other third-parties, failed or inadequate processes and technology or systems failures. The Fund relies on third-parties for a range of services, including custody. Any delay or failure relating to engaging or maintaining such service providers may affect the Fund’s ability to meet its investment objective. Although the Fund and the Adviser seek to reduce these operational risks through controls and procedures, there is no way to completely protect against such risks.

Roundhill Meme Stock ETF | STRUCTURAL ETF RISKS  
Prospectus [Line Items]  
Risk [Text Block]

STRUCTURAL ETF RISKS. The Fund is an ETF. Accordingly, it is subject to certain risks associated with its unique structure.

 

Cash Transactions Risk. The Fund may effect a portion of its creations and redemptions for cash, rather than in-kind securities. Paying redemption proceeds in cash rather than through in-kind delivery of portfolio securities may require the Fund to dispose of or sell portfolio securities or other assets at an inopportune time to obtain the cash needed to meet redemption orders. This may cause the Fund to sell a security and recognize a capital gain or loss that might not have been incurred if it had made a redemption in-kind. As a result, the Fund may pay out higher or lower annual capital gains distributions than ETFs that redeem in-kind. The use of cash creations and redemptions may also cause the Fund Shares to trade in the market at greater bid-ask spreads or greater premiums or discounts to the Fund’s net asset value (“NAV”). Furthermore, the Fund may not be able to execute cash transactions for creation and redemption purposes at the same price used to determine the Fund’s NAV. To the extent that the maximum additional charge for creation or redemption transactions is insufficient to cover the execution shortfall, the Fund’s performance could be negatively impacted.

 

Active Market Risk. Although Fund Shares are listed for trading on the Exchange, there can be no assurance that an active trading market for Fund Shares will develop or be maintained. Fund Shares trade on the Exchange at market prices that may be below, at or above the Fund’s net asset value. Securities, including Fund Shares, are subject to market fluctuations and liquidity constraints that may be caused by such factors as economic, political, or regulatory developments, changes in interest rates, and/or perceived trends in securities prices. Fund Shares could decline in value or underperform other investments.

 

Market Participants Risk. Only an Authorized Participant may engage in creation or redemption transactions directly with the Fund, and none of those Authorized Participants is obligated to engage in creation and/or redemption transactions. The Fund has a limited number of institutions that may act as Authorized Participants on an agency basis (i.e., on behalf of other market participants). To the extent that Authorized Participants exit the business or are unable to proceed with creation or redemption orders with respect to the Fund and no other Authorized Participant is able to step forward to create or redeem, Fund Shares may be more likely to trade at a premium or discount to NAV and possibly face trading halts or delisting. The Fund may also rely on a small number of third-party market makers to provide a market for the purchase and sale of Fund Shares but such market makers are under no obligation to do so. Decisions by Authorized Participants or market makers to reduce their role or step away from these activities in times of market stress could inhibit the effectiveness of the arbitrage process in maintaining the relationship between the underlying values of the Fund’s portfolio securities and the Fund’s market price. Any trading halt or other problem relating to the trading activity of these market makers or any issues disrupting the Authorized Participants’ ability to proceed with creation and/or redemption orders could result in a dramatic change in the spread between the Fund’s net asset value and the price at which Fund Shares are trading on the Exchange, which could result in a decrease in value of Fund Shares. This reduced effectiveness could result in Fund Shares trading at a premium or discount to net asset value and also in greater than normal intraday bid-ask spreads Fund Shares.

 

Costs of Buying and Selling Fund Shares. Due to the costs of buying or selling Fund Shares, including brokerage commissions imposed by brokers and bid/ask spreads, frequent trading of Fund Shares may significantly reduce investment results and an investment in Fund Shares may not be advisable for investors who anticipate regularly making small investments.

 

Premium/Discount Risk. As with all ETFs, Fund Shares may be bought and sold in the secondary market at market prices. The trading prices of Fund Shares in the secondary market may differ from the Fund’s daily NAV per share and there may be times when the market price of the shares is more than the NAV per share (premium) or less than the NAV per share (discount). If a shareholder purchases Fund Shares at a time when the market price is at a premium to the net asset value or sells Fund Shares at a time when the market price is at a discount to the NAV, the shareholder may pay more for, or receive less than, the underlying value of the Fund Shares, respectively. This risk is heightened in times of market volatility or periods of steep market declines.

 

Trading Risks. Although Fund Shares are listed for trading on the Exchange and may be traded on U.S. exchanges other than the Exchange, there can be no assurance that Fund Shares will trade with any volume, or at all, on any stock exchange. In stressed market conditions, the liquidity of Fund Shares may begin to mirror the liquidity of the Fund’s underlying portfolio holdings, which can be significantly less liquid than Fund Shares. Trading in Fund Shares on the Exchange may be halted due to market conditions or for reasons that, in the view of the Exchange, make trading in Fund Shares inadvisable. In addition, trading in Fund Shares on the Exchange is subject to trading halts caused by extraordinary market volatility pursuant to the Exchange’s “circuit breaker” rules. There can be no assurance that the requirements of the Exchange necessary to maintain the listing of the Fund will continue to be met or will remain unchanged.

Roundhill Meme Stock ETF | DEPOSITARY RECEIPTS RISK  
Prospectus [Line Items]  
Risk [Text Block]

DEPOSITARY RECEIPTS RISK. Depositary receipts may be less liquid than the underlying shares in their primary trading market. Any distributions paid to the holders of depositary receipts are usually subject to a fee charged by the depositary. Holders of depositary receipts may have limited voting rights, and investment restrictions in certain countries may adversely impact the value of depositary receipts because such restrictions may limit the ability to convert the equity shares into depositary receipts and vice versa. Such restrictions may cause the equity shares of the underlying issuer to trade at a discount or premium to the market price of the depositary receipts.

Roundhill Meme Stock ETF | EQUITY SECURITIES RISK

EQUITY SECURITIES RISK. Equity securities are subject to changes in value, and their values may be more volatile than those of other asset classes. Equity securities prices fluctuate for several reasons, including changes in investors’ perceptions of the financial condition of an issuer or the general condition of the relevant equity market, such as market volatility, or when political or economic events affecting an issuer occur. Common stock prices may be particularly sensitive to rising interest rates, as the cost of capital rises and borrowing costs increase.

INFORMATION TECHNOLOGY COMPANIES RISK. Information technology companies face intense competition, both domestically and internationally, which may have an adverse effect on profit margins. Like other technology companies, information technology companies may have limited product lines, markets, financial resources or personnel. The products of information technology companies may face obsolescence due to rapid technological developments, frequent new product introduction, unpredictable changes in growth rates and competition for the services of qualified personnel. Companies in the information technology sector are heavily dependent on patent and intellectual property rights. The loss or impairment of these rights may adversely affect the profitability of these companies. Information technology companies are facing increased government and regulatory scrutiny and may be subject to adverse government or regulatory action.

Roundhill Meme Stock ETF | MEME STOCKS RISK  
Prospectus [Line Items]  
Risk [Text Block]

MEME STOCKS RISK. Meme Stocks are characterized by high trading volumes and substantial price volatility, often driven by social media trends and investor interest. More traditional investing principles emphasize the intrinsic value of a company’s underlying business such as its cash flows, competitive position, and long-term growth prospects, when determining whether to buy or sell a particular security. In contrast, Meme Stocks often trade untethered from such fundamentals, driven instead by speculative fervor, viral momentum and in some instances coordinated buying and selling. The elevated trading volumes experienced by Meme Stocks may not persist outside of the “hype period,” potentially negatively affecting the liquidity and valuation of such stocks. While the Fund seeks to capitalize on the trading momentum associated with Meme Stocks, there is a substantial risk that such stocks may experience rapid and unpredictable price movements that could abate or reverse quickly. In the past, many Meme Stocks have had weakened underlying financial conditions, making them susceptible to substantial drops when trading momentum evaporates. Because a stock only becomes eligible for inclusion in the Fund’s portfolio after it has experienced a significant amount of liquidity and volatility, it is possible that by the time the Fund purchases shares of a Meme Stock it will have missed out on the initial gains but will nevertheless experience any subsequent decline in value. Additionally, the identification of Meme Stocks is inherently subjective and may vary. As a result, stocks that are widely recognized as Meme Stocks may not be selected for inclusion in the Fund’s portfolio. Conversely, stocks included in the Fund may not be perceived as Meme Stocks by the broader market. Investors should be aware that investing in Meme Stocks involves a high degree of risk and may not be suitable for all investors. The volatile nature of these investments may lead to significant fluctuations in the Fund’s net asset value and could result in potential loss. In the past, several high-profile Meme Stocks have been the subjects of a “short squeeze.” A short squeeze can cause significant volatility in a stock’s price, potentially resulting in rapid and unpredictable price increases as short sellers are forced to cover their positions. This market dynamic may lead to prices that are temporarily disconnected from a company’s underlying fundamentals, increasing the risk of substantial losses for investors who enter or exit positions during periods of heightened volatility. Investors should be aware that short squeezes can amplify both gains and losses and may result in illiquidity or difficulty executing trades at desired prices.

Roundhill Meme Stock ETF | MID CAPITALIZATION COMPANIES RISK  
Prospectus [Line Items]  
Risk [Text Block]

MID CAPITALIZATION COMPANIES RISK. Mid capitalization companies may be more vulnerable to adverse general market or economic developments, and their securities may be less liquid and may experience greater price volatility than larger, more established companies as a result of several factors, including limited trading volumes, fewer products or financial resources, management inexperience and less publicly available information. Accordingly, such companies are generally subject to greater market risk than larger, more established companies.

Roundhill Meme Stock ETF | NEW FUND RISK

Accordingly, such companies are generally subject to greater market risk than large and mid capitalization companies.

Roundhill Meme Stock ETF | VOLATILITY RISK

VOLATILITY RISK. Volatility is the characteristic of a security, an index or a market to fluctuate significantly in price within a short time period. The Fund will invest in securities that exhibit more volatility than the market as a whole.

Roundhill Daily 2X Long Magnificent Seven ETF | MARKET RISK  
Prospectus [Line Items]  
Risk [Text Block]

MARKET RISK. Market risk is the risk that a particular investment, or Fund Shares in general, may fall in value. Securities are subject to market fluctuations caused by real or perceived adverse economic, political, and regulatory factors or market developments, changes in interest rates, disruptions to trade, impositions of tariffs and perceived trends in securities prices. Fund Shares could decline in value or underperform other investments. In addition, local, regional or global events such as war, acts of terrorism, market manipulation, government defaults, government shutdowns, regulatory actions, political changes, diplomatic developments, the imposition of sanctions and other similar measures, spread of infectious diseases or other public health issues, recessions, natural disasters, or other events could have a significant negative impact on the Fund and its investments. Any of such circumstances could have a materially negative impact on the value of Fund Shares, the liquidity of an investment, and may result in increased market volatility. During any such events, Fund Shares may trade at increased premiums or discounts to their net asset value, the bid/ask spread on Fund Shares may widen and the returns on investment may fluctuate.

Roundhill Daily 2X Long Magnificent Seven ETF | LIQUIDITY RISK

Risk [Text Block]

LIQUIDITY RISK. The market for derivatives that reference the Magnificent Seven ETF may be subject to periods of illiquidity. During such times it may be difficult or impossible to buy or sell a position at the desired price. Market disruptions or volatility can also make it difficult to find a counterparty willing to transact at a reasonable price and sufficient size. Illiquid markets may cause losses, which could be significant. The large size of the positions which the Fund may acquire increases the risk of illiquidity, may make its positions more difficult to liquidate, and may increase the losses incurred while trying to do so. Such large positions also may impact the price of derivatives on the Magnificent Seven ETF.

The Fund may be susceptible to an increased risk of loss, including losses due to adverse events that affect the Fund’s investments more than the market as a whole, to the extent that the Fund’s investments are concentrated in the securities and/or other assets of a particular issuer or issuers, country, group of countries, region, market, industry, group of industries, sector, market segment or asset class.

COUNTERPARTY RISK. Fund transactions involving a counterparty are subject to the risk that the counterparty will not fulfill its obligation to the Fund. Counterparty risk may arise because of the counterparty’s financial condition (i.e., financial difficulties, bankruptcy, or insolvency), market activities and developments, or other reasons, whether foreseen or not. A counterparty’s inability to fulfill its obligation may result in significant financial loss to the Fund. The Fund may be unable to recover its investment from the counterparty or may obtain a limited recovery, and/or recovery may be delayed.

Roundhill Daily 2X Long Magnificent Seven ETF | CURRENT MARKET CONDITIONS RISK  
Prospectus [Line Items]  
Risk [Text Block]

CURRENT MARKET CONDITIONS RISK. Current market conditions risk is the risk that a particular investment, or Fund Shares in general, may fall in value due to current market conditions. As a means to fight inflation, which remains at elevated levels, the Federal Reserve and certain foreign central banks have raised interest rates; however, the Federal Reserve has recently lowered interest rates and may continue to do so. U.S. regulators have proposed several changes to market and issuer regulations which would directly impact the Fund, and any regulatory changes could adversely impact the Fund’s ability to achieve its investment strategies or make certain investments. Recent and potential future bank failures could result in disruption to the broader banking industry or markets generally and reduce confidence in financial institutions and the economy as a whole, which may also heighten market volatility and reduce liquidity. Additionally, challenges in commercial real estate markets, including rising interest rates, declining valuations and increasing vacancies, could have a broader impact on financial markets. The ongoing adversarial political climate in the United States, as well as political and diplomatic events both domestic and abroad, have and may continue to have an adverse impact the U.S. regulatory landscape, markets and investor behavior, which could have a negative impact on the Fund’s investments and operations. The change in administration resulting from the 2024 United States national elections could result in significant impacts to international trade relations, tax and immigration policies, and other aspects of the national and international political and financial landscape, which could affect, among other things, inflation and the securities markets generally. Other unexpected political, regulatory and diplomatic events within the U.S. and abroad may affect investor and consumer confidence and may adversely impact financial markets and the broader economy. For example, ongoing armed conflicts between Russia and Ukraine in Europe and among Israel, Iran, Hamas and other militant groups in the Middle East, have caused and could continue to cause significant market disruptions and volatility within the markets in Russia, Europe, the Middle East and the United States. The hostilities and sanctions resulting from those hostilities have and could continue to have a significant impact on certain Fund investments as well as Fund performance and liquidity. The economies of the United States and its trading partners, as well as the financial markets generally, may be adversely impacted by trade disputes, including the imposition of tariffs, and other matters. For example, the United States has imposed trade barriers and restrictions on China. In addition, the Chinese government is engaged in a longstanding dispute with Taiwan, continually threatening an invasion. If the political climate between the United States and China does not improve or continues to deteriorate, if China were to attempt invading Taiwan, or if other geopolitical conflicts develop or worsen, economies, markets and individual securities may be adversely affected, and the value of the Fund’s assets may go down. A public health crisis and the ensuing policies enacted by governments and central banks may cause significant volatility and uncertainty in global financial markets, negatively impacting global growth prospects. As the COVID-19 global pandemic illustrated, such events may affect certain geographic regions, countries, sectors and industries more significantly than others. Advancements in technology may also adversely impact markets and the overall performance of the Fund. For instance, the economy may be significantly impacted by the advanced development and increased regulation of artificial intelligence. Additionally, cyber security breaches of both government and non-government entities could have negative impacts on infrastructure and the ability of such entities, including the Fund, to operate properly. These events, and any other future events, may adversely affect the prices and liquidity of the Fund’s portfolio investments and could result in disruptions in the trading markets.

Roundhill Daily 2X Long Magnificent Seven ETF | CYBERSECURITY RISK

Risk [Text Block]

CYBERSECURITY RISK. Failures or breaches of the electronic systems of the Fund, the Fund’s adviser, sub-adviser, distributor and other service providers, market makers, Authorized Participants or the issuers of securities in which the Fund invests have the ability to cause disruptions, negatively impact the Fund’s business operations and/or potentially result in financial losses to the Fund and its shareholders. While the Fund has established business continuity plans and risk management systems seeking to address system breaches or failures, there are inherent limitations in such plans and systems. Furthermore, the Fund cannot control the cybersecurity plans and systems of the Fund’s other service providers, market makers, Authorized Participants or issuers of securities in which the Fund invests.

Roundhill Daily 2X Long Magnificent Seven ETF | DERIVATIVES RISK  
Prospectus [Line Items]  
Risk [Text Block]

DERIVATIVES RISK. The use of derivative instruments involves risks different from, or possibly greater than, the risks associated with investing directly in securities and other traditional investments. These risks include: (i) the risk that the counterparty to a derivative transaction may not fulfill its contractual obligations; (ii) risk of mispricing or improper valuation; and (iii) the risk that changes in the value of the derivative may not correlate perfectly with the underlying asset. Derivative prices are highly volatile and may fluctuate substantially during a short period of time. Such prices are influenced by numerous factors that affect the markets, including, but not limited to: changing supply and demand relationships; government programs and policies; national and international political and economic events, changes in interest rates, inflation and deflation and changes in supply and demand relationships. Trading derivative instruments involves risks different from, or possibly greater than, the risks associated with investing directly in securities. Derivative contracts ordinarily have leverage inherent in their terms. The use of leverage may cause the Fund to liquidate portfolio positions when it would not be advantageous to do so in order to satisfy its obligations or to meet regulatory or contractual requirements for derivatives. The use of derivatives can magnify potential for gain or loss and, therefore, amplify the effects of market volatility on Fund Share price.

Roundhill Daily 2X Long Magnificent Seven ETF | ETF RISK  
Prospectus [Line Items]  
Risk [Text Block]

ETF RISK. The Fund may invest significantly in ETFs. The value of an ETF held by the Fund will fluctuate over time based on fluctuations in the values of the assets held by the ETF, which may be affected by changes in general economic conditions, expectations for future growth and profits, interest rates and the supply and demand for those assets. When the Fund invests in an ETF, it will bear a proportionate share of the ETF’s expenses. Brokerage, tax and other expenses may negatively impact the performance of the ETF and, in turn, the value of the Fund Shares. An ETF that tracks an index may not exactly match the performance of the index due to cash drag, differences between the portfolio of the ETF and the components of the index, expenses and other factors.

Roundhill Daily 2X Long Magnificent Seven ETF | LEVERAGE RISK  
Prospectus [Line Items]  
Risk [Text Block]

LEVERAGE RISK. The Fund obtains investment exposure in excess of its net assets by utilizing leverage and may lose more money in market conditions that are adverse to its investment objective than a fund that does not utilize leverage. An investment in the Fund is exposed to the risk that a decline in the daily performance of the Magnificent Seven ETF will be magnified. This means that an investment in the Fund will be approximately reduced by an amount equal to 2% for every 1% daily decline in the market value of shares of the Magnificent Seven ETF, not including the costs of financing leverage and other operating expenses, which would further reduce its value. The Fund could theoretically lose an amount greater than its net assets in the event the market value of the Magnificent Seven ETF declines more than 50% in a single trading day. Leverage will also have the effect of magnifying any differences in the Fund’s correlation with the Magnificent Seven ETF.

Roundhill Daily 2X Long Magnificent Seven ETF | OPERATIONAL RISK  
Prospectus [Line Items]  
Risk [Text Block]

OPERATIONAL RISK. The Fund is subject to risks arising from various operational factors, including, but not limited to, human error, processing and communication errors, errors of the Fund’s service providers, counterparties or other third-parties, failed or inadequate processes and technology or systems failures. The Fund relies on third-parties for a range of services, including custody. Any delay or failure relating to engaging or maintaining such service providers may affect the Fund’s ability to meet its investment objective. Although the Fund and the Adviser seek to reduce these operational risks through controls and procedures, there is no way to completely protect against such risks.

Roundhill Daily 2X Long Magnificent Seven ETF | STRUCTURAL ETF RISKS  
Prospectus [Line Items]  
Risk [Text Block]

STRUCTURAL ETF RISKS. The Fund is an ETF. Accordingly, it is subject to certain risks associated with its unique structure.

 

Cash Transactions Risk. The Fund expects to effect a portion of its creations and redemptions for cash, rather than in-kind securities. Paying redemption proceeds in cash rather than through in-kind delivery of portfolio securities may require the Fund to dispose of or sell portfolio securities or other assets at an inopportune time to obtain the cash needed to meet redemption orders. This may cause the Fund to sell a security and recognize a capital gain or loss that might not have been incurred if it had made a redemption in-kind. As a result, the Fund may pay out higher or lower annual capital gains distributions than ETFs that redeem in-kind. The use of cash creations and redemptions will require the Fund to incur brokerage expenses when it buys and sells its portfolio investments and may also cause the Fund’s Shares to trade in the market at greater bid-ask spreads and greater premiums or discounts to the Fund’s net asset value (“NAV”). Furthermore, the Fund may not be able to execute cash transactions for creation and redemption purposes at the same price used to determine the Fund’s NAV. To the extent that the maximum additional charge for creation or redemption transactions is insufficient to cover the execution shortfall, the Fund’s performance could be negatively impacted.

 

Market Participants Risk. Only an Authorized Participant may engage in creation or redemption transactions directly with the Fund, and none of those Authorized Participants is obligated to engage in creation and/or redemption transactions. The Fund has a limited number of institutions that may act as Authorized Participants on an agency basis (i.e., on behalf of other market participants). To the extent that Authorized Participants exit the business or are unable to proceed with creation or redemption orders with respect to the Fund and no other Authorized Participant is able to step forward to create or redeem, Fund Shares may be more likely to trade at a premium or discount to NAV and possibly face trading halts or delisting. The Fund may also rely on a small number of third-party market makers to provide a market for the purchase and sale of Fund Shares but such market makers are under no obligation to do so. Decisions by Authorized Participants or market makers to reduce their role or step away from these activities in times of market stress could inhibit the effectiveness of the arbitrage process in maintaining the relationship between the underlying values of the Fund’s portfolio securities and the Fund’s market price. Any trading halt or other problem relating to the trading activity of these market makers or any issues disrupting the Authorized Participants’ ability to proceed with creation and/or redemption orders could result in a dramatic change in the spread between the Fund’s net asset value and the price at which Fund Shares are trading on the Exchange, which could result in a decrease in value of Fund Shares. This reduced effectiveness could result in Fund Shares trading at a premium or discount to net asset value and also in greater than normal intraday bid-ask spreads Fund Shares.

 

Costs of Buying and Selling Fund Shares. Due to the costs of buying or selling Fund Shares, including brokerage commissions imposed by brokers and bid/ask spreads, frequent trading of Fund Shares may significantly reduce investment results and an investment in Fund Shares may not be advisable for investors who anticipate regularly making small investments.

 

Premium/Discount Risk. As with all ETFs, Fund Shares may be bought and sold in the secondary market at market prices. The trading prices of Fund Shares in the secondary market may differ from the Fund’s daily NAV per share and there may be times when the market price of the shares is more than the NAV per share (premium) or less than the NAV per share (discount). If a shareholder purchases Fund Shares at a time when the market price is at a premium to the net asset value or sells Fund Shares at a time when the market price is at a discount to the NAV , the shareholder may pay more for, or receive less than, the underlying value of the Fund Shares, respectively. This risk is heightened in times of market volatility or periods of steep market declines.

 

Trading Risks. Although Fund Shares are listed for trading on the Exchange and may be traded on U.S. exchanges other than the Exchange, there can be no assurance that Fund Shares will trade with any volume, or at all, on any stock exchange. In stressed market conditions, the liquidity of Fund Shares may begin to mirror the liquidity of the Fund’s underlying portfolio holdings, which can be significantly less liquid than Fund Shares. Trading in Fund Shares on the Exchange may be halted due to market conditions or for reasons that, in the view of the Exchange, make trading in Fund Shares inadvisable. In addition, trading in Fund Shares on the Exchange is subject to trading halts caused by extraordinary market volatility pursuant to the Exchange’s “circuit breaker” rules. There can be no assurance that the requirements of the Exchange necessary to maintain the listing of the Fund will continue to be met or will remain unchanged.

Roundhill Daily 2X Long Magnificent Seven ETF | VALUATION RISK  
Prospectus [Line Items]  
Risk [Text Block]

VALUATION RISK. The Fund may hold securities or other assets that may be valued on the basis of factors other than market quotations. This may occur because the asset or security does not trade on a centralized exchange, or in times of market turmoil or reduced liquidity. There are multiple methods that can be used to value a portfolio holding when market quotations are not readily available. The value established for any portfolio holding at a point in time might differ from what would be produced using a different methodology or if it had been priced using market quotations. Portfolio holdings that are valued using techniques other than market quotations, including “fair valued” assets or securities, may be subject to greater fluctuation in their valuations from one day to the next than if market quotations were used. In addition, there is no assurance that the Fund could sell or close out a portfolio position for the value established for it at any time, and it is possible that the Fund would incur a loss because a portfolio position is sold or closed out at a discount to the valuation established by the Fund at that time. The Fund’s ability to value investments may be impacted by technological issues or errors by pricing services or other third-party service providers.

Roundhill Daily 2X Long Magnificent Seven ETF | INFORMATION TECHNOLOGY COMPANIES RISK  
Prospectus [Line Items]  
Risk [Text Block]

INFORMATION TECHNOLOGY COMPANIES RISK. Information technology companies face intense competition, both domestically and internationally, which may have an adverse effect on profit margins. Like other technology companies, information technology companies may have limited product lines, markets, financial resources or personnel. The products of information technology companies may face obsolescence due to rapid technological developments, frequent new product introduction, unpredictable changes in growth rates and competition for the services of qualified personnel. Companies in the information technology sector are heavily dependent on patent and intellectual property rights. The loss or impairment of these rights may adversely affect the profitability of these companies. Information technology companies are facing increased government and regulatory scrutiny and may be subject to adverse government or regulatory action.

Roundhill Daily 2X Long Magnificent Seven ETF | SWAP AGREEMENTS RISK  
Prospectus [Line Items]  
Risk [Text Block]

SWAP AGREEMENTS RISK. The Fund will utilize swap agreements to derive its exposure to the Magnificent Seven ETF. Swap agreements may involve greater risks than direct investment in securities as they may be leveraged and are subject to credit risk, counterparty risk and valuation risk. A swap agreement could result in losses if the underlying reference or asset does not perform as anticipated. In addition, many swaps trade over-the-counter and may be considered illiquid. It may not be possible for the Fund to liquidate a swap position at an advantageous time or price, which may result in significant losses.

Roundhill Daily 2X Long Magnificent Seven ETF | AGGRESSIVE INVESTMENT RISK

AGGRESSIVE INVESTMENT RISK. The Fund employs investment strategies that involve greater risks than the strategies used by typical funds. The Fund’s use of leverage and derivatives could result in a shareholder losing the full principal value of his/her investment within a single day.

Roundhill Daily 2X Long Magnificent Seven ETF | COMPOUNDING AND MARKET VOLATILITY RISK  
Prospectus [Line Items]  
Risk [Text Block]

COMPOUNDING AND MARKET VOLATILITY RISK. The Fund has a daily leveraged investment objective and the Fund’s performance for periods greater than a trading day will be the result of each day’s returns compounded over the period, which is very likely to differ from two times (2X) the Magnificent Seven ETF’s performance, before fees and expenses. Compounding affects all investments but has a more significant impact on funds that are leveraged and that rebalance daily. For a leveraged fund, if adverse daily performance of the reference asset reduces the amount of a shareholder’s investment, any further adverse daily performance will lead to a smaller dollar loss because the shareholder’s investment had already been reduced by the prior adverse performance. Equally, however, if favorable daily performance of the reference asset increases the amount of a shareholder’s investment, the dollar amount lost due to future adverse performance will increase because the shareholder’s investment has increased.

 

The effect of compounding becomes more pronounced as the volatility and holding period of the Fund increases. The impact of compounding will impact each shareholder differently depending on the period of time an investment in the Fund is held and the volatility of the Magnificent Seven ETF during a shareholder’s holding period of an investment in the Fund.

 

The chart below provides examples of how the volatility of the Magnificent Seven ETF could affect the Fund’s performance. The chart illustrates the impact of two factors that affect the Fund’s performance – Magnificent Seven ETF volatility and Magnificent Seven ETF returns. The Magnificent Seven ETF returns show the percentage change in the market value of the Magnificent Seven ETF over the specified period, while the Magnificent Seven ETF’s volatility is a statistical measure of the magnitude of fluctuations in the returns during that time period. As illustrated below, even if returns of the Magnificent Seven ETF over two equal time periods is identical, different volatility in the Magnificent Seven ETF (i.e., fluctuations in the rates of return) during the two time periods could result in drastically different Fund performance for the two time periods because of compounding daily returns during the time periods.

 

Fund performance for periods greater than one single day can be estimated given any set of assumptions for the following factors: (i) Magnificent Seven ETF volatility; (ii) Magnificent Seven ETF performance; (iii) period of time; (iv) financing rates associated with leveraged exposure; (v) other Fund expenses; and (vi) dividends or interest paid by the Magnificent Seven ETF. The chart shows estimated Fund returns for a number of combinations of Magnificent Seven ETF volatility and Magnificent Seven ETF performance over a one-year period. Performance shown in the chart assumes that: (a) no dividends were paid by the Magnificent Seven ETF; (b) there were no Fund expenses; and (c) borrowing/lending rates (to obtain leveraged exposure) of 0%. If Fund expenses and/or actual borrowing/lending rates were reflected, the estimated returns would be different than those shown. Particularly during periods of higher Magnificent Seven ETF volatility, compounding will cause results for periods longer than a trading day to vary from two times (2X) the performance of the Magnificent Seven ETF.

 

As shown in the chart below, the Fund would be expected to lose 6.1% if the Magnificent Seven ETF provided no return over a one-year period during which the Magnificent Seven ETF experienced annualized volatility of 25%. If the Magnificent Seven ETF’s annualized volatility were to rise to 75%, the hypothetical loss for a one-year period widens to approximately 43.1%. At higher ranges of volatility, there is a chance of a significant loss of value in the Fund, even if the Magnificent Seven ETF’s return is flat. For instance, if the Magnificent Seven ETF’s annualized volatility is 100%, the Fund would be expected to lose 63.3% of its value, even if the cumulative Magnificent Seven ETF’s return for the year was 0%. The volatility of the instruments that reflect the market value of the Magnificent Seven ETF, such as swaps, may differ from the volatility of the Magnificent Seven ETF.

 

Areas shaded red represent those scenarios where the Fund can be expected to return less than two times (2X) the performance of the Magnificent Seven ETF and those shaded green represent those scenarios where the Fund can be expected to return more than two times (2X) the performance of the Magnificent Seven ETF. The Fund’s actual returns may be significantly better or worse than the returns shown below as a result of any of the factors discussed above or in the “Daily Correlation/Tracking Risk” below.

The annualized historical volatility rate of the Magnificent Seven ETF for the period from its inception on April 10, 2023 to March 31, 2026 was 26.55%. The annualized performance of the Magnificent Seven ETF for the period from its inception on April 10, 2023 to March 31, 2026 was 34.19%. Historical Magnificent Seven ETF volatility and performance are not necessarily indications of what volatility and performance of the Magnificent Seven ETF will be in the future.

 

For information regarding the effects of volatility and Magnificent Seven ETF performance on the long-term performance of the Fund, see “Understanding the Risks and Long-Term Performance of Daily Objective Funds – the Impact of Compounding” in the Fund’s statutory prospectus.

Roundhill Daily 2X Long Magnificent Seven ETF | INTRA-DAY INVESTMENT RISK  
Prospectus [Line Items]  
Risk [Text Block]

INTRA-DAY INVESTMENT RISK. The Fund seeks leveraged investment results from the close of the market on a given trading day until the close of the market on the subsequent trading day. The exact exposure of an investment in the Fund intraday in the secondary market is a function of the difference between the market value of the Magnificent Seven ETF at the market close on the first trading day and the market value of the Magnificent Seven ETF at the time of purchase. If the market value of the Magnificent Seven ETF increases in value, the Fund’s net assets will increase by approximately two times the amount of the Fund’s exposure. Conversely, if the market value of the Magnificent Seven ETF declines in value, the Fund’s net assets will decline by approximately two times the amount of the Fund’s exposure. Thus, an investor that purchases Fund Shares intra-day may experience performance that is greater than, or less than, the Fund’s stated multiple (2X) of the Magnificent Seven ETF.

 

If there is a significant intra-day market event and/or the Magnificent Seven ETF experiences a significant decrease, the Fund may not meet its investment objective or rebalance its portfolio appropriately.

Roundhill Daily 2X Long Magnificent Seven ETF | DAILY CORRELATION/TRACKING RISK  
Prospectus [Line Items]  
Risk [Text Block]

DAILY CORRELATION/TRACKING RISK. There is no guarantee that the Fund will achieve a high degree of correlation to the Magnificent Seven ETF and therefore achieve its daily leveraged investment objective. To achieve a high degree of correlation with the Magnificent Seven ETF, the Fund seeks to rebalance its portfolio daily to keep leverage consistent with its daily leveraged investment objective. The possibility of the Fund being materially over- or under-exposed to the Magnificent Seven ETF increases on days when shares of the Magnificent Seven ETF are volatile near the close of the trading day. Market disruptions, regulatory restrictions and extreme volatility will also adversely affect the Fund’s ability to adjust exposure to the required levels.

 

The Fund may also utilize derivatives that do not use the Magnificent Seven ETF as the reference asset. Under such circumstances, the Fund’s returns may not directly correlate with the returns of the Magnificent Seven ETF. Additionally, the Fund may have difficulty achieving its daily leveraged investment objective due to fees, expenses, transaction costs, financing costs related to the use of derivatives, investments in ETFs, directly or indirectly, income items, valuation methodology, accounting standards and disruptions or illiquidity in the markets for the securities or derivatives held by the Fund. The Fund may be subject to large movements of assets into and out of the Fund, potentially resulting in the Fund being over- or under-exposed to the Magnificent Seven ETF. The Fund may take or refrain from taking positions to improve the tax efficiency or to comply with various regulatory restrictions, either of which may negatively impact the Fund’s correlation to the Magnificent Seven ETF.

Roundhill Daily 2X Long Magnificent Seven ETF | MAGNIFICENT SEVEN ETF RISKS  
Prospectus [Line Items]  
Risk [Text Block]

MAGNIFICENT SEVEN ETF RISKS. The Fund will have significant exposure to the Magnificent Seven ETF through its investments in shares of the Magnificent Seven ETF and investments in financial instruments that provide exposure to the Magnificent Seven ETF and the securities it holds. Accordingly, the Fund will subject to the risks of the Magnificent Seven ETF, set forth below. In addition to these risks, the Magnificent Seven ETF is also subject to the following risks to which the Fund is also subject, which are described within the section entitled “Principal Risks”: Active Management Risk, Active Market Risk, Asset Class Risk, Concentration Risk, Cybersecurity Risk, Information Technology Risk, Operational Risk and Structural ETF Risk.

 

EQUITY SECURITIES RISK. Equity securities are subject to changes in value, and their values may be more volatile than those of other asset classes. Equity securities prices fluctuate for several reasons, including changes in investors’ perceptions of the financial condition of an issuer or the general condition of the relevant equity market, such as market volatility, or when political or economic events affecting an issuer occur. Common stock prices may be particularly sensitive to rising interest rates, as the cost of capital rises and borrowing costs increase. Common stocks generally subject their holders to more risks than preferred stocks and debt securities because common stockholders’ claims are subordinated to those of holders of preferred stocks and debt securities upon the bankruptcy of the issuer.

 

ISSUER RISK. The performance of an ETF depends on the performance of individual securities to which the ETF has exposure. Changes in the financial condition or credit rating of an issuer of those securities may cause the value of the securities to decline. There is no guarantee that an issuer that paid dividends in the past will continue to do so in the future or will continue paying dividends at the same level.

 

LARGE CAPITALIZATION COMPANIES RISK. Large capitalization companies may be less able than smaller capitalization companies to adapt to changing market conditions. Large capitalization companies may be more mature and subject to more limited growth potential compared with smaller capitalization companies. During different market cycles, the performance of large capitalization companies has trailed the overall performance of the broader securities markets.

 

LEGISLATION AND LITIGATION RISK. Legislation or litigation that affects the value of assets or securities held by the Magnificent Seven ETF may reduce the value of the Fund. From time to time, various legislative initiatives are proposed that may have a negative impact on certain assets or securities in which the Magnificent Seven ETF invests. In addition, litigation regarding any of the assets or securities owned by the Magnificent Seven ETF may negatively impact the value of the Shares. Such legislation or litigation may cause the Fund to lose value.

Roundhill Daily 2X Long Magnificent Seven ETF | FUTURES CONTRACT RISK  
Prospectus [Line Items]  
Risk [Text Block]

FUTURES CONTRACT RISK. The Fund may utilize futures contracts. Risks of futures contracts include: (i) an imperfect correlation between the value of the futures contract and the underlying asset; (ii) possible lack of a liquid secondary market; (iii) the inability to close a futures contract when desired; (iv) losses caused by unanticipated market movements, which may be unlimited; (v) an obligation for the Fund to make daily cash payments to maintain its required margin, particularly at times when the Fund may have insufficient cash; and (vi) unfavorable execution prices from rapid selling. Unlike equities, which typically entitle the holder to a continuing stake in a corporation, futures contracts normally specify a certain date for settlement in cash based on the reference asset. As the futures contracts approach expiration, they may be replaced by similar contracts that have a later expiration. This process is referred to as “rolling.” If the market for these contracts is in “contango,” meaning that the prices of futures contracts in the nearer months are lower than the price of contracts in the distant months, the sale of the near-term month contract would be at a lower price than the longer-term contract, resulting in a cost to “roll” the futures contract. The actual realization of a potential roll cost will be dependent upon the difference in price of the near and distant contract. The costs associated with rolling futures contracts may have a significant adverse impact on the performance of the Fund.

Roundhill Daily 2X Long Magnificent Seven ETF | REGULATED INVESTMENT COMPANY TAX RISKS

Risk [Text Block]

REGULATED INVESTMENT COMPANY TAX RISKS. The Fund intends to qualify annually and to elect to be treated as a regulated investment company under the Internal Revenue Code of 1986, as amended (the “Code”). To qualify for the favorable U.S. federal income tax treatment generally accorded to regulated investment companies, the Fund must, among other things, (i) derive in each taxable year at least 90% of its gross income from dividends, interest, payments with respect to securities loans and gains from the sale or other disposition of stock, securities or foreign currencies or other income derived with respect to its business of investing in such stock, securities or currencies, or net income derived from interests in certain publicly traded partnerships; (ii) diversify its holdings so that, at the end of each quarter of the taxable year, (a) at least 50% of the market value of the Fund’s assets is represented by cash and cash items (including receivables), U.S. government securities, the securities of other regulated investment companies and other securities, with such other securities of any one issuer generally limited for the purposes of this calculation to an amount not greater than 5% of the value of the Fund’s total assets and not greater than 10% of the outstanding voting securities of such issuer, and (b) not more than 25% of the value of its total assets is invested in the securities (other than U.S. government securities or the securities of other regulated investment companies) of any one issuer, or two or more issuers which the Fund controls which are engaged in the same, similar or related trades or businesses, or the securities of one or more of certain publicly traded partnerships; and (iii) distribute at least 90% of its investment company taxable income (which includes, among other items, dividends, interest and net short-term capital gains in excess of net long-term capital losses) and at least 90% of its net tax-exempt interest income each taxable year. There are certain exceptions for failure to qualify if the failure is for reasonable cause or is de minimis, and certain corrective action is taken and certain tax payments are made by the Fund.

 

If the Fund were to fail to meet the qualifying income test or asset diversification test and fail to qualify as a RIC, it would be taxed in the same manner as an ordinary corporation, and distributions to its shareholders would not be deductible by the Fund in computing its taxable income, which would adversely affect the Fund’s performance.

NON-DIVERSIFICATION RISK. As a “non-diversified” fund, the Fund may hold a smaller number of portfolio securities than many other funds. To the extent the Fund invests in a relatively small number of issuers, a decline in the market value of a particular security held by the Fund may affect its value more than if it invested in a larger number of issuers. The value of the Fund Shares may be more volatile than the values of shares of more diversified funds.

Prospectus [Line Items]  
Risk [Text Block]

MARKET RISK. Market risk is the risk that a particular investment, or Fund Shares in general, may fall in value. Securities are subject to market fluctuations caused by real or perceived adverse economic, political, and regulatory factors or market developments, changes in interest rates, disruptions to trade, impositions of tariffs and perceived trends in securities prices. Fund Shares could decline in value or underperform other investments. In addition, local, regional or global events such as war, acts of terrorism, market manipulation, government defaults, government shutdowns, regulatory actions, political changes, diplomatic developments, the imposition of sanctions and other similar measures, spread of infectious diseases or other public health issues, recessions, natural disasters, or other events could have a significant negative impact on the Fund and its investments. Any of such circumstances could have a materially negative impact on the value of Fund Shares, the liquidity of an investment, and may result in increased market volatility. During any such events, Fund Shares may trade at increased premiums or discounts to their net asset value, the bid/ask spread on Fund Shares may widen and the returns on investment may fluctuate.

Roundhill Ether Covered Call Strategy ETF | COVERED CALL STRATEGY RISK  
Prospectus [Line Items]  
Risk [Text Block]

COVERED CALL STRATEGY RISK. A covered call strategy involves writing (selling) covered call options in return for the receipt of premiums. The seller of the option gives up the opportunity to benefit from price increases in the underlying instrument above the exercise price of the options, but continues to bear the risk of underlying instrument price declines. The premiums received from the options may not be sufficient to offset any losses sustained from underlying instrument price declines, over time. As a result, the risks associated with writing covered call options may be similar to the risks associated with writing put options. Exchanges may suspend the trading of options during periods of abnormal market volatility. Suspension of trading may mean that an option seller is unable to sell options at a time that may be desirable or advantageous to do so.

 

The covered call strategy utilized by the Fund is “synthetic” because the Fund’s exposure to the price return of the Ether ETFs is derived through options exposure, rather than direct holdings of the shares of the Ether ETFs. Because such exposure is synthetic, it is possible that the Fund’s participation in the price return of the Ether ETFs may not be as precise as if the Fund were directly holding shares of the Ether ETFs.

Roundhill Ether Covered Call Strategy ETF | OPTIONS RISK  
Prospectus [Line Items]  
Risk [Text Block]

OPTIONS RISK. The use of options involves investment strategies and risks different from those associated with ordinary portfolio securities transactions and depends on the ability of the Fund’s portfolio managers to forecast market movements correctly. The prices of options are volatile and are influenced by, among other things, actual and anticipated changes in the value of the underlying instrument, or in interest or currency exchange rates, including the anticipated volatility, which in turn are affected by fiscal and monetary policies and by national and international political and economic events. The effective use of options also depends on the Fund’s ability to terminate option positions at times deemed desirable to do so. There is no assurance that the Fund will be able to effect closing transactions at any particular time or at an acceptable price. In addition, there may at times be an imperfect correlation between the movement in values of options and their underlying securities and there may at times not be a liquid secondary market for certain options.

Roundhill Ether Covered Call Strategy ETF | LIQUIDITY RISK  
Prospectus [Line Items]  
Risk [Text Block]

LIQUIDITY RISK. The market for Ether ETF Options is still developing and may be subject to periods of illiquidity. During such times it may be difficult or impossible to buy or sell a position at the desired price. Market disruptions or volatility can also make it difficult to find a counterparty willing to transact at a reasonable price and sufficient size. Illiquid markets may cause losses, which could be significant. The large size of the positions which the Fund may acquire increases the risk of illiquidity, may make its positions more difficult to liquidate, and may increase the losses incurred while trying to do so. Such large positions also may impact the price of Ether ETF Options.

Roundhill Ether Covered Call Strategy ETF | ACTIVE MANAGEMENT RISK  
Prospectus [Line Items]  
Risk [Text Block]

ACTIVE MANAGEMENT RISK. The Fund is actively-managed and its performance reflects investment decisions that the Adviser and/or Sub-Adviser makes for the Fund. Such judgments about the Fund’s investments may prove to be incorrect. If the investments selected and the strategies employed by the Fund fail to produce the intended results, the Fund could underperform as compared to other funds with similar investment objectives and/or strategies, or could have negative returns.

Roundhill Ether Covered Call Strategy ETF | ACTIVE MARKET RISK  
Prospectus [Line Items]  
Risk [Text Block]

ACTIVE MARKET RISK. Although Fund Shares are listed for trading on the Exchange, there can be no assurance that an active trading market for Fund Shares will develop or be maintained. Fund Shares trade on the Exchange at market prices that may be below, at or above the Fund’s net asset value. Securities, including Fund Shares, are subject to market fluctuations and liquidity constraints that may be caused by such factors as economic, political, or regulatory developments, changes in interest rates, and/or perceived trends in securities prices. Fund Shares could decline in value or underperform other investments.

Roundhill Ether Covered Call Strategy ETF | ASSET CLASS RISK

ASSET CLASS RISK. Securities and other assets in the Fund’s portfolio may underperform in comparison to the general financial markets, a particular financial market or other asset classes.

Roundhill Ether Covered Call Strategy ETF | ASSIGNMENT RISK  
Prospectus [Line Items]  
Risk [Text Block]

ASSIGNMENT RISK. In response to a notification of an option holder’s desire to exercise the option held, the OCC may randomly assign the exercise notice to a clearing member, which must then assign, randomly or on a first-in-first-out basis, the obligation to a customer who has written that particular option. If the Fund is assigned an exercise notice, the Fund pays the buyer the difference between the option price on the exercise date and the option price when written by the Fund. As a result, the Fund may be forced to settle a written option position at an inopportune time and at a cost to the Fund, both of which could adversely affect the Fund’s performance and ability to track the performance of the Ether ETFs.

Roundhill Ether Covered Call Strategy ETF | CLEARING MEMBER DEFAULT RISK  
Prospectus [Line Items]  
Risk [Text Block]

CLEARING MEMBER DEFAULT RISK. Transactions in some types of derivatives, including the options held by the Fund, are required to be centrally cleared (“cleared derivatives”). In a transaction involving cleared derivatives, the Fund’s counterparty is a clearinghouse, such as the OCC, rather than a bank or broker. Since the Fund is not a member of clearinghouses, and only members of a clearinghouse (“clearing members”) can participate directly in the clearinghouse, the Fund will hold cleared derivatives through accounts at clearing members. With regard its cleared derivatives positions, the Fund will make payments (including margin payments) to, and receive payments from, a clearinghouse through their accounts at clearing members. Customer funds held at a clearing organization in connection with any option contracts are held in a commingled omnibus account and are not identified to the name of the clearing member’s individual customers. As a result, assets deposited by the Fund with any clearing member as margin for its options position may, in certain circumstances, be used to satisfy losses of other clients of the Fund’s clearing member. In addition, although clearing members guarantee performance of their clients’ obligations to the clearinghouse, there is a risk that the assets of the Fund might not be fully protected in the event of the clearing member’s bankruptcy. The Fund is also subject to the risk that a limited number of clearing members are willing to transact on the Fund’s behalf, which heightens the risks associated with a clearing member’s default. If a clearing member defaults, the Fund could lose some or all of the benefits of a transaction entered into by the Fund with the clearing member. The loss of a clearing member for the Fund to transact with could result in increased transaction costs and other operational issues that could impede the Fund’s ability to implement its investment strategy. If the Fund cannot find a clearing member to transact with on the Fund’s behalf, the Fund may be unable to effectively implement its investment strategy.

Roundhill Ether Covered Call Strategy ETF | CONCENTRATION RISK

CONCENTRATION RISK. The Fund may be susceptible to an increased risk of loss, including losses due to adverse events that affect the Fund’s investments more than the market as a whole, to the extent that the Fund’s investments are concentrated in investments that provide exposure to ether.

Roundhill Ether Covered Call Strategy ETF | COUNTERPARTY RISK  
Prospectus [Line Items]  
Risk [Text Block]

COUNTERPARTY RISK. Fund transactions involving a counterparty are subject to the risk that the counterparty will not fulfill its obligation to the Fund. Counterparty risk may arise because of the counterparty’s financial condition (i.e., financial difficulties, bankruptcy, or insolvency), market activities and developments, or other reasons, whether foreseen or not. A counterparty’s inability to fulfill its obligation may result in significant financial loss to the Fund. The Fund may be unable to recover its investment from the counterparty or may obtain a limited recovery, and/or recovery may be delayed.

Roundhill Ether Covered Call Strategy ETF | CURRENT MARKET CONDITIONS RISK  
Prospectus [Line Items]  
Risk [Text Block]

CURRENT MARKET CONDITIONS RISK. Current market conditions risk is the risk that a particular investment, or Fund Shares in general, may fall in value due to current market conditions. As a means to fight inflation, which remains at elevated levels, the Federal Reserve and certain foreign central banks have raised interest rates; however, the Federal Reserve has recently lowered interest rates and may continue to do so. U.S. regulators have proposed several changes to market and issuer regulations which would directly impact the Fund, and any regulatory changes could adversely impact the Fund’s ability to achieve its investment strategies or make certain investments. Recent and potential future bank failures could result in disruption to the broader banking industry or markets generally and reduce confidence in financial institutions and the economy as a whole, which may also heighten market volatility and reduce liquidity. Additionally, challenges in commercial real estate markets, including rising interest rates, declining valuations and increasing vacancies, could have a broader impact on financial markets. The ongoing adversarial political climate in the United States, as well as political and diplomatic events both domestic and abroad, have and may continue to have an adverse impact the U.S. regulatory landscape, markets and investor behavior, which could have a negative impact on the Fund’s investments and operations. The change in administration resulting from the 2024 United States national elections could result in significant impacts to international trade relations, tax and immigration policies, and other aspects of the national and international political and financial landscape, which could affect, among other things, inflation and the securities markets generally. Other unexpected political, regulatory and diplomatic events within the U.S. and abroad may affect investor and consumer confidence and may adversely impact financial markets and the broader economy. For example, ongoing armed conflicts between Russia and Ukraine in Europe and among Israel, Iran, Hamas and other militant groups in the Middle East, have caused and could continue to cause significant market disruptions and volatility within the markets in Russia, Europe, the Middle East and the United States. The hostilities and sanctions resulting from those hostilities have and could continue to have a significant impact on certain Fund investments as well as Fund performance and liquidity. The economies of the United States and its trading partners, as well as the financial markets generally, may be adversely impacted by trade disputes, including the imposition of tariffs, and other matters. For example, the United States has imposed trade barriers and restrictions on China. In addition, the Chinese government is engaged in a longstanding dispute with Taiwan, continually threatening an invasion. If the political climate between the United States and China does not improve or continues to deteriorate, if China were to attempt invading Taiwan, or if other geopolitical conflicts develop or worsen, economies, markets and individual securities may be adversely affected, and the value of the Fund’s assets may go down. A public health crisis and the ensuing policies enacted by governments and central banks may cause significant volatility and uncertainty in global financial markets, negatively impacting global growth prospects. As the COVID-19 global pandemic illustrated, such events may affect certain geographic regions, countries, sectors and industries more significantly than others. Advancements in technology may also adversely impact markets and the overall performance of the Fund. For instance, the economy may be significantly impacted by the advanced development and increased regulation of artificial intelligence. Additionally, cyber security breaches of both government and non-government entities could have negative impacts on infrastructure and the ability of such entities, including the Fund, to operate properly. These events, and any other future events, may adversely affect the prices and liquidity of the Fund’s portfolio investments and could result in disruptions in the trading markets.

Roundhill Ether Covered Call Strategy ETF | CYBERSECURITY RISK  
Prospectus [Line Items]  
Risk [Text Block]

CYBERSECURITY RISK. Failures or breaches of the electronic systems of the Fund, the Fund’s adviser, sub-adviser, distributor and other service providers, market makers, Authorized Participants or the issuers of securities in which the Fund invests have the ability to cause disruptions, negatively impact the Fund’s business operations and/or potentially result in financial losses to the Fund and its shareholders. While the Fund has established business continuity plans and risk management systems seeking to address system breaches or failures, there are inherent limitations in such plans and systems. Furthermore, the Fund cannot control the cybersecurity plans and systems of the Fun’s other service providers, market makers, Authorized Participants or issuers of securities in which the Fund invests.

Roundhill Ether Covered Call Strategy ETF | DEBT SECURITIES RISK  
Prospectus [Line Items]  
Risk [Text Block]

DEBT SECURITIES RISK. Investments in debt securities subject the holder to the credit risk of the issuer. Credit risk refers to the possibility that the issuer or other obligor of a security will not be able or willing to make payments of interest and principal when due. Generally, the value of debt securities will change inversely with changes in interest rates. To the extent that interest rates rise, certain underlying obligations may be paid off substantially slower than originally anticipated and the value of those securities may fall sharply. During periods of falling interest rates, the income received by the Fund may decline. If the principal on a debt security is prepaid before expected, the prepayments of principal may have to be reinvested in obligations paying interest at lower rates. Debt securities generally do not trade on a securities exchange making them generally less liquid and more difficult to value than common stock.

Roundhill Ether Covered Call Strategy ETF | DERIVATIVES RISK  
Prospectus [Line Items]  
Risk [Text Block]

DERIVATIVES RISK. The use of derivative instruments involves risks different from, or possibly greater than, the risks associated with investing directly in securities and other traditional investments. These risks include: (i) the risk that the counterparty to a derivative transaction may not fulfill its contractual obligations; (ii) risk of mispricing or improper valuation; and (iii) the risk that changes in the value of the derivative may not correlate perfectly with the underlying asset. Derivative prices are highly volatile and may fluctuate substantially during a short period of time. Such prices are influenced by numerous factors that affect the markets, including, but not limited to: changing supply and demand relationships; government programs and policies; national and international political and economic events, changes in interest rates, inflation and deflation and changes in supply and demand relationships. Trading derivative instruments involves risks different from, or possibly greater than, the risks associated with investing directly in securities. Derivative contracts ordinarily have leverage inherent in their terms. The use of leverage may cause the Fund to liquidate portfolio positions when it would not be advantageous to do so in order to satisfy its obligations or to meet regulatory or contractual requirements for derivatives. The use of derivatives can magnify potential for gain or loss and, therefore, amplify the effects of market volatility on share price.

Roundhill Ether Covered Call Strategy ETF | DISTRIBUTION TAX RISK  
Prospectus [Line Items]  
Risk [Text Block]

DISTRIBUTION TAX RISK. The Fund currently expects to make distributions on a weekly basis. These distributions may exceed the Fund’s income and gains for the Fund’s taxable year. Distributions in excess of the Fund’s current and accumulated earnings and profits will be treated as a return of capital. A return of capital distribution generally will not be taxable but will reduce the shareholder’s cost basis and will result in a higher capital gain or lower capital loss when those Fund Shares on which the distribution was received are sold. Once a Fund shareholder’s cost basis is reduced to zero, further distributions will be treated as capital gain if the Fund shareholder holds Fund Shares as capital assets. Additionally, any capital returned through distributions will be distributed after payment of Fund fees and expenses. Because a portion of the Fund’s distributions may consist of return of capital, the Fund may not be an appropriate investment for investors who do not want their principal investment in the Fund to decrease over time or who do not wish to receive return of capital in a given period. In the event that a shareholder purchases Fund Shares shortly before a distribution by the Fund, the entire distribution may be taxable to the shareholder even though a portion of the distribution effectively represents a return of the purchase price.

Roundhill Ether Covered Call Strategy ETF | ETF RISK  
Prospectus [Line Items]  
Risk [Text Block]

ETF RISK. The value of an ETF held by the Fund will fluctuate over time based on fluctuations in the values of the assets held by the ETF, which may be affected by changes in general economic conditions, expectations for future growth and profits, interest rates and the supply and demand for those assets. When the Fund invests in an ETF, it will bear a proportionate share of the ETF’s expenses. In addition, ETFs are subject to Active Market Risk, Operational Risk, Premium/Discount Risk and the Structural ETF Risks set forth below. Brokerage, tax and other expenses may negatively impact the performance of the ETF and, in turn, the value of Fund Shares.

Roundhill Ether Covered Call Strategy ETF | FLEX OPTIONS RISK  
Prospectus [Line Items]  
Risk [Text Block]

FLEX OPTIONS RISK. Trading FLEX Options involves risks different from, or possibly greater than, the risks associated with investing directly in securities. The Fund may experience losses from specific FLEX Option positions and certain FLEX Option positions may expire worthless. The FLEX Options are listed on an exchange; however, no one can guarantee that a liquid secondary trading market will exist for the FLEX Options. In the event that trading in the FLEX Options is limited or absent, the value of the Fund’s FLEX Options may decrease. In a less liquid market for the FLEX Options, liquidating the FLEX Options may require the payment of a premium (for written FLEX Options) or acceptance of a discounted price (for purchased FLEX Options) and may take longer to complete. A less liquid trading market may adversely impact the value of the FLEX Options and Fund Shares and result in the Fund being unable to achieve its investment objectives. Less liquidity in the trading of the Fund’s FLEX Options could have an impact on the prices paid or received by the Fund for the FLEX Options in connection with creations and redemptions of the Fund’s shares. Depending on the nature of this impact to pricing, the Fund may be forced to pay more for redemptions (or receive less for creations) than the price at which it currently values the FLEX Options. Such overpayment or under collection could reduce the Fund’s ability to achieve its investment objectives. Additionally, in a less liquid market for the FLEX Options, the liquidation of a large number of options may more significantly impact the price. A less liquid trading market may adversely impact the value of the FLEX Options and the value of your investment. The trading in FLEX Options may be less deep and liquid than the market for certain other exchange-traded options, non-customized options or other securities.

Roundhill Ether Covered Call Strategy ETF | INFLATION RISK

Risk [Text Block]

INFLATION RISK. Inflation risk is the risk that the value of assets or income from investments will be less in the future as inflation decreases the value of money. As inflation increases, the present value of the Fund’s assets and distributions may decline. This risk is more prevalent with respect to fixed income securities held by the Fund.

Roundhill Ether Covered Call Strategy ETF | Interest Rate Risk [Member]  
Prospectus [Line Items]  
Risk [Text Block]

INTEREST RATE RISK. Interest rate risk is the risk that the value of the debt securities in the Fund’s portfolio will decline because of rising market interest rates. Interest rate risk is generally lower for shorter term debt securities and higher for longer-term debt securities. Duration is a reasonably accurate measure of a debt security’s price sensitivity to changes in interest rates and a common measure of interest rate risk. Duration measures a debt security’s expected life on a present value basis, taking into account the debt security’s yield, interest payments and final maturity. In general, duration represents the expected percentage change in the value of a security for an immediate 1% change in interest rates. For example, the price of a debt security with a three-year duration would be expected to drop by approximately 3% in response to a 1% increase in interest rates. Therefore, prices of debt securities with shorter durations tend to be less sensitive to interest rate changes than debt securities with longer durations. As the value of a debt security changes over time, so will its duration.

Roundhill Ether Covered Call Strategy ETF | LEGISLATION AND LITIGATION RISK  
Prospectus [Line Items]  
Risk [Text Block]

LEGISLATION AND LITIGATION RISK. Legislation or litigation that affects the value of assets or securities held by the Fund may reduce the value of the Fund. From time to time, various legislative initiatives are proposed that may have a negative impact on certain assets or securities in which the Fund invests. In addition, litigation regarding any of the assets or securities owned by the Fund may negatively impact the value of Fund Shares. Such legislation or litigation may cause the Fund to lose value or may result in higher portfolio turnover if the Adviser determines to sell such a holding.

Roundhill Ether Covered Call Strategy ETF | LEVERAGE RISK  
Prospectus [Line Items]  
Risk [Text Block]

LEVERAGE RISK. While the Fund does not seek leveraged exposure to the Ether ETFs, the Fund seeks to achieve and maintain the exposure to the price of the Ether ETFs by using the leverage inherent in options contracts. Therefore, the Fund is subject to leverage risk. When the Fund purchases or sells an instrument or enters into a transaction without investing an amount equal to the full economic exposure of the instrument or transaction, it creates leverage, which can result in the Fund losing more than it originally invested. As a result, these investments may magnify losses to the Fund, and even a small market movement may result in significant losses to the Fund. Leverage may also cause the Fund to be more volatile because it may exaggerate the effect of any increase or decrease in the value of the Fund’s portfolio securities. Options trading involves a degree of leverage and as a result, a relatively small price movement in futures instruments may result in immediate and substantial losses to the Fund.

Roundhill Ether Covered Call Strategy ETF | MONEY MARKET INSTRUMENTS RISK  
Prospectus [Line Items]  
Risk [Text Block]

MONEY MARKET INSTRUMENTS RISK. The value of money market instruments may be affected by changing interest rates and by changes in the credit ratings of the investments. If a significant amount of the Fund’s assets are invested in money market instruments, it will be more difficult for the Fund to achieve its investment objectives. An investment in a money market fund is not insured or guaranteed by the FDIC or any other government agency. It is possible to lose money by investing in a money market fund.

Roundhill Ether Covered Call Strategy ETF | OPERATIONAL RISK  
Prospectus [Line Items]

OPERATIONAL RISK. The Fund is subject to risks arising from various operational factors, including, but not limited to, human error, processing and communication errors, errors of the Fund’s service providers, counterparties or other third-parties, failed or inadequate processes and technology or systems failures. The Fund relies on third-parties for a range of services, including custody. Any delay or failure relating to engaging or maintaining such service providers may affect the Fund’s ability to meet its investment objectives. Although the Fund and the Adviser seek to reduce these operational risks through controls and procedures, there is no way to completely protect against such risks.

Roundhill Ether Covered Call Strategy ETF | REVERSE REPURCHASE AGREEMENTS RISK  
Prospectus [Line Items]  
Risk [Text Block]

REVERSE REPURCHASE AGREEMENTS RISK. Reverse repurchase agreements involve both counterparty risk and the risk that the value of securities that the Fund is obligated to repurchase under the agreement may decline below the repurchase price. Reverse repurchase agreements involve leverage risk; the Fund may lose money as a result of declines in the values both of the security subject to the reverse repurchase agreement and the instruments in which the Fund invested the proceeds of the reverse repurchase agreement.

Roundhill Ether Covered Call Strategy ETF | SPECIAL TAX RISK  
Prospectus [Line Items]  
Risk [Text Block]

SPECIAL TAX RISK. The Fund intends to qualify as a RIC, however, the federal income tax treatment of certain aspects of the proposed operations of the Fund are not entirely clear. This includes the tax aspects of the Fund’s options strategy, the possible application of the “straddle” rules, and various loss limitation provisions of the Code. If, in any year, the Fund fails to qualify as a RIC under the applicable tax laws, the Fund would be taxed as an ordinary corporation.

 

To the extent that the Fund investments in Ether ETF Options include offsetting positions, the character of gains or losses realized by the Fund under the Code’s “straddle” rules may be affected and may increase the amount of short-term capital gain realized by the Fund. The Fund may hold certain options that do not qualify as “Section 1256 contracts” under Section 1256 of the Code, and disposition of such options will likely result in short-term or long-term capital gains or losses depending on the holding period.

 

The Fund intends to treat the income it derives from gains on options referencing Spot Ether ETFs as “qualifying income” for purposes of the RIC qualification rules under Subchapter M of the Code. It has adopted this position in reliance on an opinion obtained from counsel that income from such investments should constitute “qualifying income,” as Spot Ether ETFs referenced by the options constitute “securities” under Section 2(a)(36) of the 1940 Act. However, this opinion is not binding upon the Internal Revenue Service (“IRS”). If the IRS were to successfully assert that the Fund’s income from such investments was not “qualifying income,” the Fund may fail to qualify as a RIC under Subchapter M if over 10% of its gross income was derived from these investments. If the Fund failed to qualify as a RIC, it would be subject to federal and state income tax on all of its taxable income at regular corporate tax rates with no deduction for any distributions paid to shareholders, which would significantly adversely affect the returns to, and could cause substantial losses for, Fund shareholders.

 

To maintain its status as a RIC, the Fund must distribute 90% of its investment company taxable income annually. In addition, to avoid a non-deductible excise tax, the Fund must distribute 98% of its ordinary income and 98.2% of its capital gain net income. Separately, depending upon the circumstances, sales to fund redemptions could cause the Fund to recognize income that the Fund is required to distribute to maintain the Fund’s RIC status and avoid the excise tax. Funding such distributions could require additional sales, which could require more distributions and affect the projected performance of the Fund. Alternatively, if the Fund only makes distributions to maintain its RIC status and becomes subject to the excise tax, that could also affect the projected performance of the Fund. In either case, the assets sold to fund redemptions, distributions or pay the excise tax will not be available to assist the Fund in meeting its investment objectives.

 

In the event that a shareholder purchases shares of the Fund shortly before a distribution by the Fund, the entire distribution may be taxable to the shareholder even though a portion of the distribution effectively represents a return of the purchase price.

Roundhill Ether Covered Call Strategy ETF | STRUCTURAL ETF RISKS  
Prospectus [Line Items]  
Risk [Text Block]

STRUCTURAL ETF RISKS. The Fund is an ETF. Accordingly, it is subject to certain risks associated with its unique structure.

 

Cash Transactions Risk. The Fund currently expects to effect a significant portion of its creations and redemptions for cash, rather than in-kind securities. Paying redemption proceeds in cash rather than through in-kind delivery of portfolio securities may require the Fund to dispose of or sell portfolio securities or other assets at an inopportune time to obtain the cash needed to meet redemption orders. This may cause the Fund to sell a security and recognize a capital gain or loss that might not have been incurred if it had made a redemption in-kind. As a result, the Fund may pay out higher or lower annual capital gains distributions than ETFs that redeem in-kind. The use of cash creations and redemptions may also cause the Fund’s Shares to trade in the market at greater bid-ask spreads or greater premiums or discounts to the Fund’s net asset value (“NAV”. Furthermore, the Fund may not be able to execute cash transactions for creation and redemption purposes at the same price used to determine the Fund’s NAV. To the extent that the maximum additional charge for creation or redemption transactions is insufficient to cover the execution shortfall, the Fund’s performance could be negatively impacted.

 

Market Participants Risk. Only an Authorized Participant may engage in creation or redemption transactions directly with the Fund, and none of those Authorized Participants is obligated to engage in creation and/or redemption transactions. The Fund has a limited number of institutions that may act as Authorized Participants on an agency basis (i.e., on behalf of other market participants). To the extent that Authorized Participants exit the business or are unable to proceed with creation or redemption orders with respect to the Fund and no other Authorized Participant is able to step forward to create or redeem, Fund Shares may be more likely to trade at a premium or discount to NAV and possibly face trading halts or delisting. The Fund may also rely on a small number of third-party market makers to provide a market for the purchase and sale of Fund Shares but such market makers are under no obligation to do so. Decisions by Authorized Participants or market makers to reduce their role or step away from these activities in times of market stress could inhibit the effectiveness of the arbitrage process in maintaining the relationship between the underlying values of the Fund’s portfolio securities and the Fund’s market price. Any trading halt or other problem relating to the trading activity of these market makers or any issues disrupting the Authorized Participants’ ability to proceed with creation and/or redemption orders could result in a dramatic change in the spread between the Fund’s net asset value and the price at which Fund Shares are trading on the Exchange, which could result in a decrease in value of Fund Shares. This reduced effectiveness could result in Fund Shares trading at a premium or discount to net asset value and also in greater than normal intraday bid-ask spreads Fund Shares.

 

Costs of Buying and Selling Fund Shares. Due to the costs of buying or selling Fund Shares, including brokerage commissions imposed by brokers and bid/ask spreads, frequent trading of Fund Shares may significantly reduce investment results and an investment in Fund Shares may not be advisable for investors who anticipate regularly making small investments.

 

Premium/Discount Risk. As with all ETFs, Fund Shares may be bought and sold in the secondary market at market prices. The trading prices of Fund Shares in the secondary market may differ from the Fund’s daily NAV per share and there may be times when the market price of Fund Shares is more than the NAV per Fund Share (premium) or less than the net asset value per Fund Share (discount). If a shareholder purchases Fund Shares at a time when the market price is at a premium to the NAV or sells Fund Shares at a time when the market price is at a discount to the NAV, the shareholder may pay more for, or receive less than, the underlying value of the Fund Shares, respectively. This risk is heightened in times of market volatility or periods of steep market declines.

 

Trading Risks. Although Fund Shares are listed for trading on the Exchange and may be traded on U.S. exchanges other than the Exchange, there can be no assurance that Fund Shares will trade with any volume, or at all, on any stock exchange. In stressed market conditions, the liquidity of Fund Shares may begin to mirror the liquidity of the Fund’s underlying portfolio holdings, which can be significantly less liquid than Fund Shares. Trading in Fund Shares on the Exchange may be halted due to market conditions or for reasons that, in the view of the Exchange, make trading in Fund Shares inadvisable. In addition, trading in Fund Shares on the Exchange is subject to trading halts caused by extraordinary market volatility pursuant to the Exchange’s “circuit breaker” rules. There can be no assurance that the requirements of the Exchange necessary to maintain the listing of the Fund will continue to be met or will remain unchanged.

Risk [Text Block]

U.S. GOVERNMENT SECURITIES RISK. U.S. government securities are subject to interest rate risk but generally do not involve the credit risks associated with investments in other types of debt securities. As a result, the yields available from U.S. government securities are generally lower than the yields available from other debt securities. U.S. government securities are guaranteed only as to the timely payment of interest and the payment of principal when held to maturity.

Roundhill Ether Covered Call Strategy ETF | VALUATION RISK  
Prospectus [Line Items]  
Risk [Text Block]

VALUATION RISK. The Fund may hold securities or other assets that may be valued on the basis of factors other than market quotations. This may occur because the asset or security does not trade on a centralized exchange, or in times of market turmoil or reduced liquidity. There are multiple methods that can be used to value a portfolio holding when market quotations are not readily available. The value established for any portfolio holding at a point in time might differ from what would be produced using a different methodology or if it had been priced using market quotations. Portfolio holdings that are valued using techniques other than market quotations, including “fair valued” assets or securities, may be subject to greater fluctuation in their valuations from one day to the next than if market quotations were used. In addition, there is no assurance that the Fund or an Ether ETF could sell or close out a portfolio position for the value established for it at any time, and it is possible that the Fund or an Ether ETF would incur a loss because a portfolio position is sold or closed out at a discount to the valuation established by the Fund or an Ether ETF at that time. The Fund’s or an Ether ETF’s ability to value investments may be impacted by technological issues or errors by pricing services or other third-party service providers.

PORTFOLIO TURNOVER RISK. High portfolio turnover may result in the Fund paying higher levels of transaction costs and may generate greater tax liabilities for shareholders. Portfolio turnover risk may cause the Fund’s performance to be less than expected. 

Roundhill Ether Covered Call Strategy ETF | ETHER ETF RISKS  
Prospectus [Line Items]  
Risk [Text Block]

ETHER ETF RISKS. The Fund will have significant exposure to the Ether ETFs through its Ether ETF Option positions. Accordingly, the Fund will be subject to the risks of the Ether ETFs, set forth below. In addition to these risks, the Ether ETFs are also subject to the following risks to which the Fund is also subject, which are described within the section entitled “Principal Risks”: Active Market Risk, Asset Class Risk, Concentration Risk, Cybersecurity Risk, Legislation and Litigation Risk, Operational Risk and Structural ETF Risk.

 

ETHER RISK. Ether is subject to significant volatility, rapid price fluctuations, and uncertainty. While ether has experienced substantial growth in institutional adoption, regulatory recognition, and technological maturity, its value remains influenced by market sentiment, speculative investment activities, macroeconomic factors, and ongoing technological developments rather than purely traditional fundamental analysis. Ethereum is an evolving blockchain platform that continues to undergo substantial upgrades, such as the transition from Proof-of-Work to Proof-of-Stake (Ethereum 2.0 or the “Merge”) and the ongoing rollout of scalability improvements (including Layer 2 solutions such as rollups). These complex technological upgrades are intended to improve Ethereum’s scalability, security, transaction throughput, energy efficiency, and usability. However, each significant update introduces risks including technical vulnerabilities, potential software flaws, delays in development, operational disruptions, or unintended economic impacts, any of which could negatively affect investor confidence, the adoption of the Ethereum blockchain, or ether’s valuation. The regulatory environment for ether and the Ethereum blockchain remains uncertain and varied globally. While certain jurisdictions have provided increased regulatory clarity and oversight, significant regulatory risks persist. Unanticipated regulatory actions—including enforcement actions, reclassification of ether’s regulatory status (such as a security versus commodity), or significant policy changes—could materially impact ether’s value and liquidity. Investors should remain aware that shifts in regulatory classification or compliance requirements may adversely impact the viability, market perception, or utility of ether. The Ethereum ecosystem relies heavily on smart contracts—computer code deployed on the Ethereum blockchain capable of automating financial transactions, asset management, and decentralized application (dApp) functionalities. While smart contracts enable substantial innovation, they remain vulnerable to coding errors, exploitation, hacks, and manipulation. Past security breaches involving decentralized finance (DeFi) platforms, decentralized exchanges, and smart contract-based projects have led to significant financial losses, adversely affecting market sentiment, investor confidence, and ether’s valuation. Competition from other blockchain networks, sometimes referred to as “Ethereum alternatives” or “Layer 1 competitors,” remains robust. Networks offering potentially superior scalability, lower transaction fees, enhanced privacy, or specific technical advantages—such as Solana, Avalanche, Cardano, Polkadot, and others—continue to attract users, developers, and investors. Successful adoption and growth of competing blockchain ecosystems could limit Ethereum’s market share, ecosystem development, and thus negatively impact ether’s long-term valuation. Furthermore, the Ethereum network faces potential governance risks. Decisions regarding protocol upgrades, network policies, or operational changes depend on community consensus among diverse stakeholders, including core developers, validators, decentralized autonomous organizations (DAOs), and other influential actors. Disagreements or governance failures within the Ethereum community could result in contentious blockchain forks, fragmentation of resources, diminished market confidence, or value dilution.

 

CUSTODY RISK. Security breaches, computer malware and computer hacking attacks have been a prevalent concern in relation to digital assets. The ether held by the Ether ETFs’ custodian will likely be an appealing target to hackers or malware distributors seeking to destroy, damage or steal the Ether ETFs’ ether. To the extent that the Ether ETFs and their service providers are unable to identify and mitigate or stop new security threats or otherwise adapt to technological changes in the digital asset industry, an Ether ETF’s ether may be subject to theft, loss, destruction or other attack. The Ether ETFs have put security procedures in place to prevent such theft, loss or destruction, including but not limited to, offline storage, or cold storage, multiple encrypted private key “shards”, and other measures. Nevertheless, the security procedures cannot guarantee the prevention of any loss due to a security breach, software defect or act of God that may be borne by the Ether ETFs and the security procedures may not protect against all errors, software flaws or other vulnerabilities in an Ether ETF’s technical infrastructure, which could result in theft, loss or damage of its assets. The Ether ETFs do not control the operations of their service providers or their implementation of such security procedures and there can be no assurance that such security procedures will actually work as designed or prove to be successful in safeguarding an Ether ETF’s assets against all possible sources of theft, loss or damage. Assets not held in cold storage, such as assets held in a trading account, may be more vulnerable to security breach, hacking or loss than assets held in cold storage. Furthermore, assets held in a trading account are held on an omnibus, rather than segregated basis, which creates greater risk of loss. The security procedures and operational infrastructure may be breached due to the actions of outside parties, error or malfeasance of an employee of an Ether ETF’s service providers, and, as a result, an unauthorized party may obtain access to the Ether ETF’s account at the custodian where its ether is held, the relevant private keys (and therefore ether) or other data or property of a Ether ETF. Additionally, outside parties may attempt to fraudulently induce employees of an Ether ETF or its service providers to disclose sensitive information in order to gain access to an Ether ETF’s infrastructure. As the techniques used to obtain unauthorized access, disable or degrade service, or sabotage systems change frequently, or may be designed to remain dormant until a predetermined event and often are not recognized until launched against a target, an Ether ETF and its service providers may be unable to anticipate these techniques or implement adequate preventative measures.

 

DIGITAL ASSET TRADING PLATFORMS RISK. Digital asset trading platforms remain relatively new and vary significantly in terms of regulation, transparency, operational stability, and compliance standards. While certain prominent trading platforms—particularly those based in the United States—have substantially improved transparency, compliance, and regulatory adherence, many platforms still operate internationally or offshore with significantly less stringent oversight. Platforms located outside the United States may be subject to minimal or inconsistent regulatory enforcement and often do not provide sufficient public information regarding their management structure, ownership, financial stability, cybersecurity practices, or compliance controls. Despite increased institutional involvement, enhanced security measures, and more standardized operating practices adopted by leading platforms, digital asset exchanges continue to be vulnerable to cybersecurity threats, hacking incidents, fraudulent activities, operational disruptions, and other technical risks. High-profile failures, breaches, or shutdowns of major trading platforms or custodians—such as those arising from fraud, cybersecurity incidents, regulatory enforcement actions, or insolvency—can significantly reduce investor confidence, increase market volatility, and potentially trigger contagion effects across the digital asset ecosystem. Regulatory developments and enforcement actions continue to shape the landscape in which digital asset platforms operate. Recent regulatory scrutiny has heightened globally, particularly in jurisdictions with substantial trading volumes, such as the United States, Europe, and Asia. Increased regulatory oversight, while potentially positive for market stability in the long run, can create short-term disruption, reduce liquidity, prompt platform closures, or alter business models substantially, thereby affecting the prices of digital assets, including ether. Investors should be aware that trading or custodying ether on less transparent or poorly regulated platforms increases the risk of losing access to digital assets due to platform insolvency, hacking incidents, regulatory intervention, or operational failure. Although improvements have been made, the digital asset marketplace remains inherently riskier than traditional financial markets, and investors may have limited recourse if a digital asset trading platform fails or is compromised.

 

IRREVOCABILITY OF TRANSACTIONS RISK. Ether transactions are typically not reversible without the consent and active participation of the recipient of the transaction. Once a transaction has been verified and recorded in a block that is added to the Ethereum blockchain, an incorrect transfer or theft of ether generally will not be reversible and an Ether ETF may not be capable of seeking compensation for any such transfer or theft. It is possible that, through computer or human error, or through theft or criminal action, an Ether ETF’s ether could be transferred from an Ether ETF’s account at its custodian in incorrect amounts or to unauthorized third parties, or to uncontrolled accounts.

 

TRADING HALT RISK. Trading in shares of an Ether ETF on U.S. securities exchanges may be halted due to market conditions or for reasons that, in the view of an exchange, make trading in shares of an Ether ETF inadvisable. In addition, trading of shares of an Ether ETF on securities exchanges is subject to trading halts caused by extraordinary market volatility pursuant to an exchange’s “circuit breaker” rules. Shares of an Ether ETF may be at a higher risk of a trading halt due to the volatility of ether. In the event that shares of an Ether ETF are subject to a trading halt, the Fund’s ability to pursue its principal investment strategy may be impaired and the Fund may be negatively affected.

 

VOLATILITY RISK. The price of ether remains highly volatile and subject to significant price fluctuations. While recent increases in institutional adoption, clearer regulatory frameworks, and broader market acceptance have contributed to greater stability relative to earlier periods, the price of ether continues to be influenced by rapid shifts in market sentiment, regulatory developments, macroeconomic conditions, technological advancements, and unforeseen events. The market price of ether has historically experienced dramatic highs and lows over short periods, often with limited or no identifiable catalyst. Given the evolving nature of digital asset markets, price volatility may be amplified by external factors such as changes in global financial markets, geopolitical events, regulatory enforcement actions, or significant technological or security incidents. Furthermore, speculative trading, leveraged positions, and derivatives markets tied to ether continue to contribute to potential volatility. Investors should remain aware that sudden, substantial price movements may occur at any time, potentially leading to significant losses. Consequently, investments linked directly or indirectly to ether, including Ether ETFs, may experience heightened volatility compared to traditional investment products.

Roundhill Ether Covered Call Strategy ETF | ETHER FUTURES ETF RISKS  
Prospectus [Line Items]  
Risk [Text Block]

ETHER FUTURES ETF RISKS. The Fund may have exposure to Ether ETFs through Ether ETF Options that utilize an Ether Futures ETF as the reference asset. Accordingly, in addition to the risks set forth above in “Ether ETFs Risk,” the Fund will be subject to the risks of an Ether Futures ETF, set forth below.

 

ETHER FUTURES RISK. The market for ether futures contracts may be less developed, and potentially less liquid and more volatile, than more established futures markets. While the market for ether futures contracts has grown substantially since ether futures contracts commenced trading, there can be no assurance that this growth will continue. The price for ether futures contracts is based on a number of factors, including the supply of and the demand for ether futures contracts. Market conditions and expectations, position limits, accountability levels, collateral requirements, availability of counterparties, and other factors each can impact the supply of and demand for ether futures contracts. Additionally, due to the high margin requirements that are unique to ether futures contracts, an Ether Futures ETF may experience difficulty maintaining the desired level of exposure to ether futures contracts. If an Ether Futures ETF is unable to achieve such exposure it may not be able to meet its investment objective and the fund’s returns may be different or lower than expected. Additionally, collateral requirements may require an Ether Futures ETF to liquidate its positions, potentially incurring losses and expenses, when it otherwise would not do so. Investing in derivatives like ether futures contracts may be considered aggressive and may expose an Ether Futures ETF to significant risks. These risks include counterparty risk and liquidity risk.

 

ETHER FUTURES CAPACITY RISK. If an Ether Futures ETF’s ability to obtain exposure to ether futures contracts consistent with its investment objective is disrupted for any reason including, for example, limited liquidity in the ether futures contracts market, a disruption to the ether futures contracts market, or as a result of margin requirements, position limits, accountability levels, or other limitations imposed by an Ether Future ETF’s futures commission merchants (“FCMs”), the listing exchanges, or the CFTC, an Ether Futures ETF may not be able to achieve its investment objective and may experience significant losses.

 

Any disruption in an Ether Futures ETF’s ability to obtain exposure to ether futures contracts will cause the Ether Futures ETF’s performance to deviate from the performance of ether futures contracts, and consequently, ether. Additionally, the ability of an Ether Futures ETF to obtain exposure to ether futures contracts may be limited by certain tax rules that limit the amount an Ether Futures ETF can invest in its wholly-owned subsidiary as of the end of each tax quarter. Exceeding this amount may have tax consequences.

 

COST OF FUTURES INVESTMENT RISK. When an ether futures contract is nearing expiration, an Ether Futures ETF will “roll” the futures contract, which means it will generally sell the ether futures contract and use the proceeds to buy an ether futures contract with a later expiration date. When rolling futures contracts that are in contango, an Ether Futures ETF would sell a lower priced, expiring contract and purchase a higher priced, longer-dated contract. The price difference between the expiring contract and longer-dated contract associated with rolling futures contracts is typically substantially higher than the price difference associated with rolling other futures contracts. Ether futures contracts have historically experienced extended periods of contango. Contango in the ether futures contracts market may have a significant adverse impact on the performance of an Ether Futures ETF and may cause ether futures contracts, and an Ether Futures ETF, to underperform the current price of ether. Both contango and backwardation would reduce an Ether Futures ETF’s correlation to the current price of ether and may limit or prevent an Ether Futures ETF from achieving its investment objective.

 

CLEARING BROKER RISK. An Ether Futures ETF’s investments in exchange-traded futures contracts expose it to the risks of a clearing broker (or an FCM). Under current regulations, a clearing broker or FCM maintains customers’ assets in a bulk segregated account. There is a risk that the assets of an Ether Futures ETF deposited with the clearing broker to serve as margin may be used to satisfy the broker’s own obligations or the losses of the broker’s other clients. In the event of default, an Ether Futures ETF could experience lengthy delays in recovering some or all of its assets and may not see any recovery at all. Furthermore, an Ether Futures ETF is subject to the risk that no FCM is willing or able to clear the Fund’s transactions or maintain an Ether Futures ETF’s assets. If an Ether Futures ETF’s FCMs are unable or unwilling to clear an Ether Futures ETF’s transactions, or if the FCM refuses to maintain an Ether Futures ETF’s assets, an Ether Futures ETF will be unable have its orders for ether futures contracts fulfilled or assets custodied. In such a circumstance, the performance of an Ether Futures ETF will likely deviate from the performance of ether and may result in the proportion of ether futures contracts in an Ether Futures ETF’s portfolio relative to the total assets of an Ether Futures ETF to decrease.

 

COMMODITY REGULATORY RISK. An Ether Futures ETF’s use of commodities futures subject to regulation by the CFTC has caused an Ether Futures ETF to be classified as a “commodity pool” and this designation requires that an Ether Futures ETF comply with CFTC rules, which may impose additional regulatory requirements and compliance obligations. An Ether Futures ETF’s investment decisions may need to be modified, and commodity contract positions held by an Ether Futures ETF may have to be liquidated at disadvantageous times or prices, to avoid exceeding any applicable position limits established by the CFTC, potentially subjecting an Ether Futures ETF to substantial losses. The regulation of commodity transactions in the United States is subject to ongoing modification by government, self-regulatory and judicial action. The effect of any future regulatory change with respect to any aspect of an Ether Futures ETF is impossible to predict, but could be substantial and adverse to an Ether Futures ETF.

 

FUTURES CONTRACT RISK. Risks of futures contracts include: (i) an imperfect correlation between the value of the futures contract and the underlying asset; (ii) possible lack of a liquid secondary market; (iii) the inability to close a futures contract when desired; (iv) losses caused by unanticipated market movements, which may be unlimited; (v) an obligation for an Ether Futures ETF to make daily cash payments to maintain its required margin, particularly at times when an Ether Futures ETF may have insufficient cash; and (vi) unfavorable execution prices from rapid selling. Unlike equities, which typically entitle the holder to a continuing stake in a corporation, futures contracts normally specify a certain date for settlement in cash based on the reference asset. As the futures contracts approach expiration, they may be replaced by similar contracts that have a later expiration. This process is referred to as “rolling.” If the market for these contracts is in “contango,” meaning that the prices of futures contracts in the nearer months are lower than the price of contracts in the distant months, the sale of the near-term month contract would be at a lower price than the longer-term contract, resulting in a cost to “roll” the futures contract. The actual realization of a potential roll cost will be dependent upon the difference in price of the near and distant contract. The costs associated with rolling ether futures contracts may have a significant adverse impact on the performance of the Ether Futures ETF.

 

SUBSIDIARY INVESTMENT RISK. Changes in the laws of the United States and/or the Cayman Islands, under which certain Ether Futures ETFs and their wholly-owned Cayman subsidiaries are organized, respectively, could result in the inability of an Ether Futures ETF to operate as intended and could negatively affect an Ether Futures ETF and its shareholders (such as the Fund). An Ether Futures ETF’s Cayman subsidiary is not registered under the 1940 Act and is not subject to all the investor protections of the 1940 Act.

NON-DIVERSIFICATION RISK. As a “non-diversified” fund, the Fund may hold a smaller number of portfolio securities than many other funds. To the extent the Fund invests in a relatively small number of issuers, a decline in the market value of a particular security held by the Fund may affect its value more than if it invested in a larger number of issuers. The value of the Fund Shares may be more volatile than the values of shares of more diversified funds.

Roundhill GLP-1 & Weight Loss ETF | MARKET RISK  
Prospectus [Line Items]  
Risk [Text Block]

MARKET RISK. Market risk is the risk that a particular investment, or Fund Shares in general, may fall in value. Securities are subject to market fluctuations caused by real or perceived adverse economic, political, and regulatory factors or market developments, changes in interest rates, disruptions to trade, impositions of tariffs and perceived trends in securities prices. Fund Shares could decline in value or underperform other investments. In addition, local, regional or global events such as war, acts of terrorism, market manipulation, government defaults, government shutdowns, regulatory actions, political changes, diplomatic developments, the imposition of sanctions and other similar measures, spread of infectious diseases or other public health issues, recessions, natural disasters, or other events could have a significant negative impact on the Fund and its investments. Any of such circumstances could have a materially negative impact on the value of Fund Shares, the liquidity of an investment, and may result in increased market volatility. During any such events, Fund Shares may trade at increased premiums or discounts to their net asset value, the bid/ask spread on Fund Shares may widen and the returns on investment may fluctuate.

Roundhill GLP-1 & Weight Loss ETF | ACTIVE MANAGEMENT RISK

ACTIVE MANAGEMENT RISK. The Fund is actively-managed and its performance reflects investment decisions that the Adviser and/or Sub-Adviser makes for the Fund. Such judgments about the Fund’s investments may prove to be incorrect. If the investments selected and the strategies employed by the Fund fail to produce the intended results, the Fund could underperform as compared to other funds with similar investment objectives and/or strategies, or could have negative returns.

CONCENTRATION RISK. The Fund is concentrated in the industry or group of industries comprising the health care sector. The Fund may be susceptible to an increased risk of loss, including losses due to adverse events that affect the Fund’s investments more than the market as a whole, to the extent that the Fund’s investments are concentrated in the securities and/or other assets of a particular issuer or issuers, country, group of countries, region, market, industry, group of industries, sector, market segment or asset class.

Roundhill GLP-1 & Weight Loss ETF | CURRENT MARKET CONDITIONS RISK  
Prospectus [Line Items]  
Risk [Text Block]

CURRENT MARKET CONDITIONS RISK. Current market conditions risk is the risk that a particular investment, or Fund Shares in general, may fall in value due to current market conditions. As a means to fight inflation, which remains at elevated levels, the Federal Reserve and certain foreign central banks have raised interest rates; however, the Federal Reserve has recently lowered interest rates and may continue to do so. U.S. regulators have proposed several changes to market and issuer regulations which would directly impact the Fund, and any regulatory changes could adversely impact the Fund’s ability to achieve its investment strategies or make certain investments. Recent and potential future bank failures could result in disruption to the broader banking industry or markets generally and reduce confidence in financial institutions and the economy as a whole, which may also heighten market volatility and reduce liquidity. Additionally, challenges in commercial real estate markets, including rising interest rates, declining valuations and increasing vacancies, could have a broader impact on financial markets. The ongoing adversarial political climate in the United States, as well as political and diplomatic events both domestic and abroad, have and may continue to have an adverse impact the U.S. regulatory landscape, markets and investor behavior, which could have a negative impact on the Fund’s investments and operations. The change in administration resulting from the 2024 United States national elections could result in significant impacts to international trade relations, tax and immigration policies, and other aspects of the national and international political and financial landscape, which could affect, among other things, inflation and the securities markets generally. Other unexpected political, regulatory and diplomatic events within the U.S. and abroad may affect investor and consumer confidence and may adversely impact financial markets and the broader economy. For example, ongoing armed conflicts between Russia and Ukraine in Europe and among Israel, Iran, Hamas and other militant groups in the Middle East, have caused and could continue to cause significant market disruptions and volatility within the markets in Russia, Europe, the Middle East and the United States. The hostilities and sanctions resulting from those hostilities have and could continue to have a significant impact on certain Fund investments as well as Fund performance and liquidity. The economies of the United States and its trading partners, as well as the financial markets generally, may be adversely impacted by trade disputes, including the imposition of tariffs, and other matters. For example, the United States has imposed trade barriers and restrictions on China. In addition, the Chinese government is engaged in a longstanding dispute with Taiwan, continually threatening an invasion. If the political climate between the United States and China does not improve or continues to deteriorate, if China were to attempt invading Taiwan, or if other geopolitical conflicts develop or worsen, economies, markets and individual securities may be adversely affected, and the value of the Fund’s assets may go down. A public health crisis and the ensuing policies enacted by governments and central banks may cause significant volatility and uncertainty in global financial markets, negatively impacting global growth prospects. As the COVID-19 global pandemic illustrated, such events may affect certain geographic regions, countries, sectors and industries more significantly than others. Advancements in technology may also adversely impact markets and the overall performance of the Fund. For instance, the economy may be significantly impacted by the advanced development and increased regulation of artificial intelligence. Additionally, cyber security breaches of both government and non-government entities could have negative impacts on infrastructure and the ability of such entities, including the Fund, to operate properly. These events, and any other future events, may adversely affect the prices and liquidity of the Fund’s portfolio investments and could result in disruptions in the trading markets.

Roundhill GLP-1 & Weight Loss ETF | CYBERSECURITY RISK  
Prospectus [Line Items]  
Risk [Text Block]

CYBERSECURITY RISK. Failures or breaches of the electronic systems of the Fund, the Fund’s adviser, sub-adviser, distributor, and other service providers, market makers, Authorized Participants or the issuers of securities in which the Fund invests have the ability to cause disruptions, negatively impact the Fund’s business operations and/or potentially result in financial losses to the Fund and its shareholders. While the Fund has established business continuity plans and risk management systems seeking to address system breaches or failures, there are inherent limitations in such plans and systems. Furthermore, the Fund cannot control the cybersecurity plans and systems of the Fund’s other service providers, market makers, Authorized Participants or issuers of securities in which the Fund invests.

Roundhill GLP-1 & Weight Loss ETF | OPERATIONAL RISK  
Prospectus [Line Items]  
Risk [Text Block]

OPERATIONAL RISK. The Fund is subject to risks arising from various operational factors, including, but not limited to, human error, processing and communication errors, errors of the Fund’s service providers, counterparties or other third-parties, failed or inadequate processes and technology or systems failures. The Fund relies on third-parties for a range of services, including custody. Any delay or failure relating to engaging or maintaining such service providers may affect the Fund’s ability to meet its investment objective. Although the Fund and the Adviser seek to reduce these operational risks through controls and procedures, there is no way to completely protect against such risks.

Roundhill GLP-1 & Weight Loss ETF | STRUCTURAL ETF RISKS  
Prospectus [Line Items]  
Risk [Text Block]

STRUCTURAL ETF RISKS. The Fund is an ETF. Accordingly, it is subject to certain risks associated with its unique structure.

 

Market Participants Risk. Only an Authorized Participant may engage in creation or redemption transactions directly with the Fund, and none of those Authorized Participants is obligated to engage in creation and/or redemption transactions. The Fund has a limited number of institutions that may act as Authorized Participants on an agency basis (i.e., on behalf of other market participants). To the extent that Authorized Participants exit the business or are unable to proceed with creation or redemption orders with respect to the Fund and no other Authorized Participant is able to step forward to create or redeem, Fund Shares may be more likely to trade at a premium or discount to NAV and possibly face trading halts or delisting. The Fund may also rely on a small number of third-party market makers to provide a market for the purchase and sale of Fund Shares but such market makers are under no obligation to do so. Decisions by Authorized Participants or market makers to reduce their role or step away from these activities in times of market stress could inhibit the effectiveness of the arbitrage process in maintaining the relationship between the underlying values of the Fund’s portfolio securities and the Fund’s market price. Any trading halt or other problem relating to the trading activity of these market makers or any issues disrupting the Authorized Participants’ ability to proceed with creation and/or redemption orders could result in a dramatic change in the spread between the Fund’s net asset value and the price at which Fund Shares are trading on the Exchange, which could result in a decrease in value of Fund Shares. This reduced effectiveness could result in Fund Shares trading at a premium or discount to net asset value and also in greater than normal intraday bid-ask spreads Fund Shares.

 

Costs of Buying and Selling Fund Shares. Due to the costs of buying or selling Fund Shares, including brokerage commissions imposed by brokers and bid/ask spreads, frequent trading of Fund Shares may significantly reduce investment results and an investment in Fund Shares may not be advisable for investors who anticipate regularly making small investments.

 

Premium/Discount Risk. As with all ETFs, Fund Shares may be bought and sold in the secondary market at market prices. The trading prices of Fund Shares in the secondary market may differ from the Fund’s daily NAV per share and there may be times when the market price of the shares is more than the NAV per share (premium) or less than the NAV per share (discount). If a shareholder purchases Fund Shares at a time when the market price is at a premium to the net asset value or sells Fund Shares at a time when the market price is at a discount to the NAV, the shareholder may pay more for, or receive less than, the underlying value of the Fund Shares, respectively. This risk is heightened in times of market volatility or periods of steep market declines.

 

Trading Risks. Although Fund Shares are listed for trading on the Exchange and may be traded on U.S. exchanges other than the Exchange, there can be no assurance that Fund Shares will trade with any volume, or at all, on any stock exchange. In stressed market conditions, the liquidity of Fund Shares may begin to mirror the liquidity of the Fund’s underlying portfolio holdings, which can be significantly less liquid than Fund Shares.

Roundhill GLP-1 & Weight Loss ETF | DEPOSITARY RECEIPTS RISK  
Prospectus [Line Items]  
Risk [Text Block]

DEPOSITARY RECEIPTS RISK. Depositary receipts may be less liquid than the underlying shares in their primary trading market. Any distributions paid to the holders of depositary receipts are usually subject to a fee charged by the depositary. Holders of depositary receipts may have limited voting rights, and investment restrictions in certain countries may adversely impact the value of depositary receipts because such restrictions may limit the ability to convert the equity shares into depositary receipts and vice versa. Such restrictions may cause the equity shares of the underlying issuer to trade at a discount or premium to the market price of the depositary receipts.

Roundhill GLP-1 & Weight Loss ETF | EQUITY SECURITIES RISK  
Prospectus [Line Items]  
Risk [Text Block]

EQUITY SECURITIES RISK. Equity securities are subject to changes in value, and their values may be more volatile than those of other asset classes. Equity securities prices fluctuate for several reasons, including changes in investors’ perceptions of the financial condition of an issuer or the general condition of the relevant equity market, such as market volatility, or when political or economic events affecting an issuer occur. Common stock prices may be particularly sensitive to rising interest rates, as the cost of capital rises and borrowing costs increase. Common stocks generally subject their holders to more risks than preferred stocks and debt securities because common stockholders’ claims are subordinated to those of holders of preferred stocks and debt securities upon the bankruptcy of the issuer.

Roundhill GLP-1 & Weight Loss ETF | INTERNATIONAL CLOSED MARKET TRADING RISK  
Prospectus [Line Items]  
Risk [Text Block]

INTERNATIONAL CLOSED MARKET TRADING RISK. To the extent securities held by the Fund trade on non-U.S. exchanges that are closed when the Fund’s primary listing exchange is open, there are likely to be deviations between the current price of an underlying security and the last quoted price for the underlying security (i.e., the Fund’s quote from the closed foreign market) used for purposes of calculating the Fund’s net asset value (“NAV”), resulting in premiums or discounts to the Fund’s NAV and bid/ask spreads that may be greater than those experienced by other funds. In addition, shareholders may not be able to purchase and sell shares of the Fund on days when the NAV of the Fund could be significantly affected by events in the relevant foreign markets.

Roundhill GLP-1 & Weight Loss ETF | ISSUER RISK  
Prospectus [Line Items]  
Risk [Text Block]

ISSUER RISK. The performance of the Fund depends on the performance of individual securities to which the Fund has exposure. Changes in the financial condition or credit rating of an issuer of those securities may cause the value of the securities to decline. There is no guarantee that an issuer that paid dividends in the past will continue to do so in the future or will continue paying dividends at the same level.

Roundhill GLP-1 & Weight Loss ETF | LARGE CAPITALIZATION COMPANIES RISK

LARGE CAPITALIZATION COMPANIES RISK. Large capitalization companies may be less able than smaller capitalization companies to adapt to changing market conditions. Large capitalization companies may be more mature and subject to more limited growth potential compared with smaller capitalization companies. During different market cycles, the performance of large capitalization companies has trailed the overall performance of the broader securities markets.

Roundhill GLP-1 & Weight Loss ETF | NON-U.S. SECURITIES RISK  
Prospectus [Line Items]  
Risk [Text Block]

NON-U.S. SECURITIES RISK. Non-U.S. securities are subject to higher volatility than securities of domestic issuers due to possible adverse political, social or economic developments, restrictions on foreign investment or exchange of securities, capital controls, lack of liquidity, currency exchange rates, excessive taxation, government seizure of assets, the imposition of sanctions by foreign governments, different legal or accounting standards, and less government supervision and regulation of securities exchanges in foreign countries.

Roundhill GLP-1 & Weight Loss ETF | MID CAPITALIZATION COMPANIES RISK

Risk [Text Block]

MID CAPITALIZATION COMPANIES RISK. Mid capitalization companies may be more vulnerable to adverse general market or economic developments, and their securities may be less liquid and may experience greater price volatility than larger, more established companies as a result of several factors, including limited trading volumes, fewer products or financial resources, management inexperience and less publicly available information. Accordingly, such companies are generally subject to greater market risk than larger, more established companies.

Roundhill GLP-1 & Weight Loss ETF | SMALL CAPITALIZATION COMPANIES RISK

SMALL CAPITALIZATION COMPANIES RISK. Small capitalization companies may be more vulnerable to adverse general market or economic developments, and their securities may be less liquid and may experience greater price volatility than large and mid capitalization companies as a result of several factors, including limited trading volumes, fewer products or financial resources, management inexperience and less publicly available information. Accordingly, such companies are generally subject to greater market risk than large and mid capitalization companies.

Roundhill GLP-1 & Weight Loss ETF | HEALTH CARE COMPANIES RISK

HEALTH CARE COMPANIES RISK. Health care companies, such as companies providing medical and healthcare goods and services, companies engaged in manufacturing medical equipment, supplies and pharmaceuticals, as well as operating health care facilities and the provision of managed health care, may be affected by government regulations and government health care programs, increases or decreases in the cost of medical products and services and product liability claims, among other factors. Many health care companies are heavily dependent on patent protection, and the expiration of a company’s patent may adversely affect that company’s profitability. Health care companies are also subject to competitive forces that may result in price discounting, may be thinly capitalized and susceptible to product obsolescence.

Roundhill GLP-1 & Weight Loss ETF | PHARMACEUTICAL COMPANIES RISK

PHARMACEUTICAL COMPANIES RISK. The Fund may have significant exposure to pharmaceutical companies in connection with its investments in GLP-1 & Weight Loss Companies. Pharmaceuticals companies may be affected by industry competition, dependency on a limited number of products, obsolescence of products, government approvals and regulations, loss or impairment of intellectual property rights and litigation regarding product liability. Pharmaceutical are subject to competitive forces that may make it difficult to raise prices of their products and may result in price discounting. The profitability of some pharmaceuticals companies may be dependent on a relatively limited number of products. The research and development costs required to bring a new product to market are substantial with no guarantee that the product will ever become profitable. Many new products are subject to gaining the approval of the FDA, which can be long and costly. Many pharmaceutical companies are heavily dependent on patents and intellectual property rights. The loss or impairment of these rights may adversely affect the profitability of these companies. Pharmaceuticals companies may also be subject to extensive litigation based on product liability and similar claims.

BIOTECHNOLOGY COMPANIES RISK. The Fund may have significant exposure to biotechnology companies in connection with its investments in GLP-1 & Weight Loss Companies. Biotechnology companies invest heavily in research and development which may not necessarily lead to commercially successful products. Biotechnology companies are subject to increased governmental regulation which may delay or inhibit the release of new products. The effects of high development costs and increased regulation may be exacerbated by a company’s inability to raise prices to cover costs because of managed care pressure or price controls. Many biotechnology companies are dependent upon their ability to use and enforce intellectual property rights and patents. Any impairment of such rights may have adverse financial consequences. Biotechnology stocks, especially those issued by smaller, less-seasoned companies, tend to be more volatile than the overall market. Biotechnology companies can also be significantly affected by technological change and obsolescence, product liability lawsuits and consequential high insurance costs.

Roundhill GLP-1 & Weight Loss ETF | EUROPE RISK

Risk [Text Block]

EUROPE RISK. The Fund may invest significantly in the securities of European issuers. As a result, beyond the typical risks associated with investing in non-U.S. securities, the Fund faces specific risks tied to European issuers. Political or economic instability in European countries can negatively impact the value of European securities and, consequently, the Fund’s portfolio. A significant number of countries in Europe are member states in the European Union (“EU”), and the member states no longer control their own monetary policies by directing independent interest rates for their currencies. Instead, the European Central Bank manages monetary policy for these member states, including the money supply and official interest rates for the Euro. Factors such as reduced imports or exports, changes in government or EU trade regulations, fluctuations in the Euro’s exchange rate, the possibility of an EU member defaulting on its sovereign debt, or an economic downturn in an EU country can significantly affect the economies of EU members and Europe overall. Measures taken by European governments and central banks to address financial challenges, such as austerity programs and reforms, may not achieve their intended goals, could lead to social unrest, restrict future economic growth and recovery, or have unforeseen consequences. Additional defaults or debt restructurings by governments or other entities could further harm economies, financial markets, and asset values globally. The EU also faces challenges related to its membership, structure, and policies. If one or more countries leave the EU, as seen with the United Kingdom’s “Brexit,” the departing country’s currency and banking system could experience severe difficulties. Further exits could cause greater market volatility, reduced liquidity, and slower economic growth in affected regions, potentially impacting the Fund’s investments. Recent concerns about security, immigration, conflict, geopolitical tensions, and terrorism may also negatively affect European countries. Additionally, a number of Eastern European countries are still developing and may be especially vulnerable to political and economic changes.

LINE OF BUSINESS RISK. Certain companies included in the Fund’s portfolio will be engaged in other lines of business unrelated to the development of GLP-1 & Weight Loss Drugs, and these lines of business could adversely affect their operating results. The operating results of these companies may fluctuate as a result of these additional risks and events in the other lines of business. Despite a company’s possible success in activities linked to its development of GLP-1 & Weight Loss Drugs, there can be no assurance that the other lines of business in which these companies are engaged will not have an adverse effect on a company’s business or financial condition.

NON-DIVERSIFICATION RISK. As a “non-diversified” fund, the Fund may hold a smaller number of portfolio securities than many other funds. To the extent the Fund invests in a relatively small number of issuers, a decline in the market value of a particular security held by the Fund may affect its value more than if it invested in a larger number of issuers. The value of the Fund Shares may be more volatile than the values of shares of more diversified funds.

Roundhill Innovation-100 0DTE Covered Call Strategy ETF | MARKET RISK  
Prospectus [Line Items]  
Risk [Text Block]

MARKET RISK. Market risk is the risk that a particular investment, or Fund Shares in general, may fall in value. Securities are subject to market fluctuations caused by real or perceived adverse economic, political, and regulatory factors or market developments, changes in interest rates, disruptions to trade, impositions of tariffs and perceived trends in securities prices. Fund Shares could decline in value or underperform other investments. In addition, local, regional or global events such as war, acts of terrorism, market manipulation, government defaults, government shutdowns, regulatory actions, political changes, diplomatic developments, the imposition of sanctions and other similar measures, spread of infectious diseases or other public health issues, recessions, natural disasters, or other events could have a significant negative impact on the Fund and its investments. Any of such circumstances could have a materially negative impact on the value of Fund Shares, the liquidity of an investment, and may result in increased market volatility. During any such events, Fund Shares may trade at increased premiums or discounts to their net asset value, the bid/ask spread on Fund Shares may widen and the returns on investment may fluctuate.

Roundhill Innovation-100 0DTE Covered Call Strategy ETF | COVERED CALL STRATEGY RISK  
Prospectus [Line Items]  
Risk [Text Block]

COVERED CALL STRATEGY RISK. A covered call strategy involves writing (selling) covered call options in return for the receipt of premiums. The seller of the option gives up the opportunity to benefit from value increases in the Innovation-100 Index above the strike price of the sold call options, but continues to bear the risk of Innovation-100 Index price declines. The premiums received from the options may not be sufficient to offset any losses sustained from Innovation-100 Index price declines. Exchanges may suspend the trading of options during periods of abnormal market volatility. Suspension of trading may mean that an option seller is unable to sell options at a time that may be desirable or advantageous to do so.

 

Additionally, the Fund is a “synthetic” covered call strategy, meaning that it derives its long exposure to the Innovation-100 Index from options that utilize the Innovation-100 Index as the reference asset. This synthetic exposure increases the likelihood that the Fund’s returns may not always precisely align with the returns of the Innovation-100 Index.

Roundhill Innovation-100 0DTE Covered Call Strategy ETF | OPTIONS RISK  
Prospectus [Line Items]  
Risk [Text Block]

OPTIONS RISK. The use of options involves investment strategies and risks different from those associated with ordinary portfolio securities transactions and depends on the ability of the Fund’s portfolio managers to forecast market movements correctly. The prices of options are volatile and are influenced by, among other things, actual and anticipated changes in the value of the underlying instrument, or in interest or currency exchange rates, including the anticipated volatility, which in turn are affected by fiscal and monetary policies and by national and international political and economic events. The effective use of options also depends on the Fund’s ability to terminate option positions at times deemed desirable to do so. There is no assurance that the Fund will be able to effect closing transactions at any particular time or at an acceptable price. In addition, there may at times be an imperfect correlation between the movement in values of options and their underlying securities and there may at times not be a liquid secondary market for certain options. Lastly, the trading of options is subject to transaction costs that may impact the Fund’s returns.

Roundhill Innovation-100 0DTE Covered Call Strategy ETF | LIQUIDITY RISK  
Prospectus [Line Items]

LIQUIDITY RISK. The market for options may be subject to periods of illiquidity. During such times it may be difficult or impossible to buy or sell a position at the desired price. Market disruptions or volatility can also make it difficult to find a counterparty willing to transact at a reasonable price and sufficient size. Illiquid markets may cause losses, which could be significant. The large size of the positions which the Fund may acquire increases the risk of illiquidity, may make its positions more difficult to liquidate, and may increase the losses incurred while trying to do so. Such large positions also may impact the price of options held by the Fund.

Roundhill Innovation-100 0DTE Covered Call Strategy ETF | ACTIVE MANAGEMENT RISK

ACTIVE MANAGEMENT RISK. The Fund is actively-managed and its performance reflects investment decisions that the Adviser and/or Sub-Adviser makes for the Fund. Such judgments about the Fund’s investments may prove to be incorrect. If the investments selected and the strategies employed by the Fund fail to produce the intended results, the Fund could underperform as compared to other funds with similar investment objectives and/or strategies, or could have negative returns.

ACTIVE MARKET RISK. Although Fund Shares are listed for trading on the Exchange, there can be no assurance that an active trading market for Fund Shares will develop or be maintained. Fund Shares trade on the Exchange at market prices that may be below, at or above the Fund’s net asset value. Securities, including Fund Shares, are subject to market fluctuations and liquidity constraints that may be caused by such factors as economic, political, or regulatory developments, changes in interest rates, and/or perceived trends in securities prices. Fund Shares could decline in value or underperform other investments.

Roundhill Innovation-100 0DTE Covered Call Strategy ETF | CLEARING MEMBER DEFAULT RISK  
Prospectus [Line Items]  
Risk [Text Block]

CLEARING MEMBER DEFAULT RISK. Transactions in some types of derivatives, including the options held by the Fund, are required to be centrally cleared (“cleared derivatives”). In a transaction involving cleared derivatives, the Fund’s counterparty is a clearinghouse, such as the OCC, rather than a bank or broker. Since the Fund is not a member of clearinghouses, and only members of a clearinghouse (“clearing members”) can participate directly in the clearinghouse, the Fund will hold cleared derivatives through accounts at clearing members. With regard its cleared derivatives positions, the Fund will make payments (including margin payments) to, and receive payments from, a clearinghouse through their accounts at clearing members. Customer funds held at a clearing organization in connection with any option contracts are held in a commingled omnibus account and are not identified to the name of the clearing member’s individual customers. As a result, assets deposited by the Fund with any clearing member as margin for its options position may, in certain circumstances, be used to satisfy losses of other clients of the Fund’s clearing member. In addition, although clearing members guarantee performance of their clients’ obligations to the clearinghouse, there is a risk that the assets of the Fund might not be fully protected in the event of the clearing member’s bankruptcy. The Fund is also subject to the risk that a limited number of clearing members are willing to transact on the Fund’s behalf, which heightens the risks associated with a clearing member’s default. If a clearing member defaults, the Fund could lose some or all of the benefits of a transaction entered into by the Fund with the clearing member. The loss of a clearing member for the Fund to transact with could result in increased transaction costs and other operational issues that could impede the Fund’s ability to implement its investment strategy. If the Fund cannot find a clearing member to transact with on the Fund’s behalf, the Fund may be unable to effectively implement its investment strategy.

Roundhill Innovation-100 0DTE Covered Call Strategy ETF | CONCENTRATION RISK

CONCENTRATION RISK. The Fund may be susceptible to an increased risk of loss, including losses due to adverse events that affect the Fund’s investments more than the market as a whole, to the extent that the Fund’s investments are concentrated in the securities and/or other assets of a particular issuer or issuers, country, group of countries, region, market, industry, group of industries, sector, market segment or asset class.

Roundhill Innovation-100 0DTE Covered Call Strategy ETF | CURRENT MARKET CONDITIONS RISK  
Prospectus [Line Items]  
Risk [Text Block]

CURRENT MARKET CONDITIONS RISK. Current market conditions risk is the risk that a particular investment, or Fund Shares in general, may fall in value due to current market conditions. As a means to fight inflation, which remains at elevated levels, the Federal Reserve and certain foreign central banks have raised interest rates; however, the Federal Reserve has recently lowered interest rates and may continue to do so. U.S. regulators have proposed several changes to market and issuer regulations which would directly impact the Fund, and any regulatory changes could adversely impact the Fund’s ability to achieve its investment strategies or make certain investments. Recent and potential future bank failures could result in disruption to the broader banking industry or markets generally and reduce confidence in financial institutions and the economy as a whole, which may also heighten market volatility and reduce liquidity. Additionally, challenges in commercial real estate markets, including rising interest rates, declining valuations and increasing vacancies, could have a broader impact on financial markets. The ongoing adversarial political climate in the United States, as well as political and diplomatic events both domestic and abroad, have and may continue to have an adverse impact the U.S. regulatory landscape, markets and investor behavior, which could have a negative impact on the Fund’s investments and operations. The change in administration resulting from the 2024 United States national elections could result in significant impacts to international trade relations, tax and immigration policies, and other aspects of the national and international political and financial landscape, which could affect, among other things, inflation and the securities markets generally. Other unexpected political, regulatory and diplomatic events within the U.S. and abroad may affect investor and consumer confidence and may adversely impact financial markets and the broader economy. For example, ongoing armed conflicts between Russia and Ukraine in Europe and among Israel, Iran, Hamas and other militant groups in the Middle East, have caused and could continue to cause significant market disruptions and volatility within the markets in Russia, Europe, the Middle East and the United States. The hostilities and sanctions resulting from those hostilities have and could continue to have a significant impact on certain Fund investments as well as Fund performance and liquidity. The economies of the United States and its trading partners, as well as the financial markets generally, may be adversely impacted by trade disputes, including the imposition of tariffs, and other matters. For example, the United States has imposed trade barriers and restrictions on China. In addition, the Chinese government is engaged in a longstanding dispute with Taiwan, continually threatening an invasion. If the political climate between the United States and China does not improve or continues to deteriorate, if China were to attempt invading Taiwan, or if other geopolitical conflicts develop or worsen, economies, markets and individual securities may be adversely affected, and the value of the Fund’s assets may go down. A public health crisis and the ensuing policies enacted by governments and central banks may cause significant volatility and uncertainty in global financial markets, negatively impacting global growth prospects. As the COVID-19 global pandemic illustrated, such events may affect certain geographic regions, countries, sectors and industries more significantly than others. Advancements in technology may also adversely impact markets and the overall performance of the Fund. For instance, the economy may be significantly impacted by the advanced development and increased regulation of artificial intelligence. Additionally, cyber security breaches of both government and non-government entities could have negative impacts on infrastructure and the ability of such entities, including the Fund, to operate properly. These events, and any other future events, may adversely affect the prices and liquidity of the Fund’s portfolio investments and could result in disruptions in the trading markets.

Roundhill Innovation-100 0DTE Covered Call Strategy ETF | CYBERSECURITY RISK  
Prospectus [Line Items]  
Risk [Text Block]

CYBERSECURITY RISK. Failures or breaches of the electronic systems of the Fund, the Fund’s adviser, sub-adviser, distributor and other service providers, market makers, Authorized Participants or the issuers of securities in which the Fund invests have the ability to cause disruptions, negatively impact the Fund’s business operations and/or potentially result in financial losses to the Fund and its shareholders. While the Fund has established business continuity plans and risk management systems seeking to address system breaches or failures, there are inherent limitations in such plans and systems. Furthermore, the Fund cannot control the cybersecurity plans and systems of the Fun’s other service providers, market makers, Authorized Participants or issuers of securities in which the Fund invests.

Roundhill Innovation-100 0DTE Covered Call Strategy ETF | DERIVATIVES RISK  
Prospectus [Line Items]  
Risk [Text Block]

DERIVATIVES RISK. The use of derivative instruments (i.e. options contracts) involves risks different from, or possibly greater than, the risks associated with investing directly in securities and other traditional investments. These risks include: (i) the risk that the counterparty to a derivative transaction may not fulfill its contractual obligations; (ii) risk of mispricing or improper valuation; and (iii) the risk that changes in the value of the derivative may not correlate perfectly with the underlying asset. Derivative prices are highly volatile and may fluctuate substantially during a short period of time. Such prices are influenced by numerous factors that affect the markets, including, but not limited to: changing supply and demand relationships; government programs and policies; national and international political and economic events, changes in interest rates, inflation and deflation and changes in supply and demand relationships. Trading derivative instruments involves risks different from, or possibly greater than, the risks associated with investing directly in securities. Derivative contracts ordinarily have leverage inherent in their terms. The use of leverage may cause the Fund to liquidate portfolio positions when it would not be advantageous to do so in order to satisfy its obligations or to meet regulatory or contractual requirements for derivatives. The use of derivatives can magnify potential for gain or loss and, therefore, amplify the effects of market volatility on the Fund Share price.

Roundhill Innovation-100 0DTE Covered Call Strategy ETF | DISTRIBUTION TAX RISK  
Prospectus [Line Items]  
Risk [Text Block]

DISTRIBUTION TAX RISK. The Fund currently expects to make distributions on a weekly basis. These distributions may exceed the Fund’s income and gains for the Fund’s taxable year. Distributions in excess of the Fund’s current and accumulated earnings and profits will be treated as a return of capital. A return of capital distribution generally will not be taxable but will reduce the shareholder’s cost basis and will result in a higher capital gain or lower capital loss when those Fund Shares on which the distribution was received are sold. Once a Fund shareholder’s cost basis is reduced to zero, further distributions will be treated as capital gain if the Fund shareholder holds Fund Shares as capital assets. Additionally, any capital returned through distributions will be distributed after payment of Fund fees and expenses. Because a portion of the Fund’s distributions will likely consist of return of capital, the Fund may not be an appropriate investment for investors who do not want their principal investment in the Fund to decrease over time or who do not wish to receive return of capital in a given period. In the event that a shareholder purchases Fund Shares shortly before a distribution by the Fund, the entire distribution may be taxable to the shareholder even though a portion of the distribution effectively represents a return of the purchase price.

Roundhill Innovation-100 0DTE Covered Call Strategy ETF | ETF RISK  
Prospectus [Line Items]

ETF RISK. The Fund’s investment in shares of ETFs subjects it to the risks of owning the securities underlying the ETF, as well as the same structural risks faced by an investor purchasing Fund Shares, including Active Management Risk, Active Market Risk, Asset Class Risk, Cybersecurity Risk, Operational Risk and Structural ETF Risk. As a shareholder in another ETF, the Fund bears its proportionate share of the ETF’s expenses, subjecting Fund shareholders to duplicative expenses.

Roundhill Innovation-100 0DTE Covered Call Strategy ETF | FLEX OPTIONS RISK  
Prospectus [Line Items]  
Risk [Text Block]

FLEX OPTIONS RISK. Trading FLEX Options involves risks different from, or possibly greater than, the risks associated with investing directly in securities. The Fund may experience losses from specific FLEX Option positions and certain FLEX Option positions may expire worthless. The FLEX Options are listed on an exchange; however, no one can guarantee that a liquid secondary trading market will exist for the FLEX Options. In the event that trading in the FLEX Options is limited or absent, the value of the Fund’s FLEX Options may decrease. In a less liquid market for the FLEX Options, liquidating the FLEX Options may require the payment of a premium (for written FLEX Options) or acceptance of a discounted price (for purchased FLEX Options) and may take longer to complete. A less liquid trading market may adversely impact the value of the FLEX Options and Fund shares and result in the Fund being unable to achieve its investment objectives. Less liquidity in the trading of the Fund’s FLEX Options could have an impact on the prices paid or received by the Fund for the FLEX Options in connection with creations and redemptions of the Fund’s Shares. Depending on the nature of this impact to pricing, the Fund may be forced to pay more for redemptions (or receive less for creations) than the price at which it currently values the FLEX Options. Such overpayment or under collection could reduce the Fund’s ability to achieve its investment objectives. Additionally, in a less liquid market for the FLEX Options, the liquidation of a large number of options may more significantly impact the price. A less liquid trading market may adversely impact the value of the FLEX Options and the value of your investment. The trading in FLEX Options may be less deep and liquid than the market for certain other exchange-traded options, non-customized options or other securities.

Roundhill Innovation-100 0DTE Covered Call Strategy ETF | INFLATION RISK

INFLATION RISK. Inflation risk is the risk that the value of assets or income from investments will be less in the future as inflation decreases the value of money. As inflation increases, the present value of the Fund’s assets and distributions may decline. This risk is more prevalent with respect to fixed income securities held by the Fund.

Roundhill Innovation-100 0DTE Covered Call Strategy ETF | OPERATIONAL RISK

Risk [Text Block]

OPERATIONAL RISK. The Fund is subject to risks arising from various operational factors, including, but not limited to, human error, processing and communication errors, errors of the Fund’s service providers, counterparties or other third-parties, failed or inadequate processes and technology or systems failures. The Fund relies on third-parties for a range of services, including custody. Any delay or failure relating to engaging or maintaining such service providers may affect the Fund’s ability to meet its investment objectives. Although the Fund and the Adviser seek to reduce these operational risks through controls and procedures, there is no way to completely protect against such risks.

Roundhill Innovation-100 0DTE Covered Call Strategy ETF | SPECIAL TAX RISK  
Prospectus [Line Items]  
Risk [Text Block]

SPECIAL TAX RISK. The Fund intends to invest a portion of its assets in options on indexes. The treatment of such derivatives may, in part, be based upon informal guidance issued by the Internal Revenue Service a number of years ago. Although the Fund believes that the Fund is treating such derivatives consistently with current tax law, if the Internal Revenue Service were to disagree, the Fund could lose its status as a regulated investment company or “RIC.” If the Fund did not qualify as a RIC for any taxable year and certain relief provisions were not available, the Fund’s taxable income would be subject to tax at the Fund level and to a further tax at the shareholder level when such income is distributed. In such event, in order to re-qualify for taxation as a RIC, the Fund might be required to recognize unrealized gains, pay substantial taxes and interest and make certain distributions. This would cause investors to incur higher tax liabilities than they otherwise would have incurred and would have a negative impact on Fund returns. In such event, the Fund’s Board of Trustees may determine to reorganize or close the Fund or materially change the Fund’s investment objectives and strategies.

Roundhill Innovation-100 0DTE Covered Call Strategy ETF | STRUCTURAL ETF RISKS  
Prospectus [Line Items]  
Risk [Text Block]

STRUCTURAL ETF RISKS. The Fund is an ETF. Accordingly, it is subject to certain risks associated with its unique structure.

 

Cash Transactions Risk. The Fund will effect a significant portion of its creations and redemptions for cash, rather than in-kind securities. Paying redemption proceeds in cash rather than through in-kind delivery of portfolio securities may require the Fund to dispose of or sell portfolio securities or other assets at an inopportune time to obtain the cash needed to meet redemption orders. This may cause the Fund to sell a security and recognize a capital gain or loss that might not have been incurred if it had made a redemption in-kind. As a result, the Fund may pay out higher or lower annual capital gains distributions than ETFs that redeem in-kind. The use of cash creations and redemptions may also cause the Fund Shares to trade in the market at greater bid-ask spreads or greater premiums or discounts to the Fund’s net asset value (“NAV”). Furthermore, the Fund may not be able to execute cash transactions for creation and redemption purposes at the same price used to determine the Fund’s NAV. To the extent that the maximum additional charge for creation or redemption transactions is insufficient to cover the execution shortfall, the Fund’s performance could be negatively impacted.

 

Market Participants Risk. Only an Authorized Participant may engage in creation or redemption transactions directly with the Fund, and none of those Authorized Participants is obligated to engage in creation and/or redemption transactions. The Fund has a limited number of institutions that may act as Authorized Participants on an agency basis (i.e., on behalf of other market participants). To the extent that Authorized Participants exit the business or are unable to proceed with creation or redemption orders with respect to the Fund and no other Authorized Participant is able to step forward to create or redeem, Fund Shares may be more likely to trade at a premium or discount to NAV and possibly face trading halts or delisting. The Fund may also rely on a small number of third-party market makers to provide a market for the purchase and sale of Fund Shares but such market makers are under no obligation to do so. Decisions by Authorized Participants or market makers to reduce their role or step away from these activities in times of market stress could inhibit the effectiveness of the arbitrage process in maintaining the relationship between the underlying values of the Fund’s portfolio securities and the Fund’s market price. Any trading halt or other problem relating to the trading activity of these market makers or any issues disrupting the Authorized Participants’ ability to proceed with creation and/or redemption orders could result in a dramatic change in the spread between the Fund’s net asset value and the price at which Fund Shares are trading on the Exchange, which could result in a decrease in value of Fund Shares. This reduced effectiveness could result in Fund Shares trading at a premium or discount to net asset value and also in greater than normal intraday bid-ask spreads Fund Shares.

 

Costs of Buying and Selling Fund Shares. Due to the costs of buying or selling Fund Shares, including brokerage commissions imposed by brokers and bid/ask spreads, frequent trading of Fund Shares may significantly reduce investment results and an investment in Fund Shares may not be advisable for investors who anticipate regularly making small investments.

 

Premium/Discount Risk. As with all ETFs, Fund Shares may be bought and sold in the secondary market at market prices. The trading prices of Fund Shares in the secondary market may differ from the Fund’s daily NAV per share and there may be times when the market price of the shares is more than the NAV per share (premium) or less than the NAV per share (discount). If a shareholder purchases Fund Shares at a time when the market price is at a premium to the NAV or sells Fund Shares at a time when the market price is at a discount to the NAV, the shareholder may pay more for, or receive less than, the underlying value of the Fund Shares, respectively. This risk is heightened in times of market volatility or periods of steep market declines.

 

Trading Risks. Although Fund Shares are listed for trading on the Exchange and may be traded on U.S. exchanges other than the Exchange, there can be no assurance that Fund Shares will trade with any volume, or at all, on any stock exchange. In stressed market conditions, the liquidity of Fund Shares may begin to mirror the liquidity of the Fund’s underlying portfolio holdings, which can be significantly less liquid than Fund Shares. Trading in Fund Shares on the Exchange may be halted due to market conditions or for reasons that, in the view of the Exchange, make trading in Fund Shares inadvisable. In addition, trading in Fund Shares on the Exchange is subject to trading halts caused by extraordinary market volatility pursuant to the Exchange’s “circuit breaker” rules. There can be no assurance that the requirements of the Exchange necessary to maintain the listing of the Fund will continue to be met or will remain unchanged.

Roundhill Innovation-100 0DTE Covered Call Strategy ETF | VALUATION RISK  
Prospectus [Line Items]  
Risk [Text Block]

VALUATION RISK. The Fund may hold securities or other assets that may be valued on the basis of factors other than market quotations. This may occur because the asset or security does not trade on a centralized exchange, or in times of market turmoil or reduced liquidity. There are multiple methods that can be used to value a portfolio holding when market quotations are not readily available. The value established for any portfolio holding at a point in time might differ from what would be produced using a different methodology or if it had been priced using market quotations. Portfolio holdings that are valued using techniques other than market quotations, including “fair valued” assets or securities, may be subject to greater fluctuation in their valuations from one day to the next than if market quotations were used. In addition, there is no assurance that the Fund could sell or close out a portfolio position for the value established for it at any time, and it is possible that the Fund would incur a loss because a portfolio position is sold or closed out at a discount to the valuation established by the Fund at that time. The Fund’s ability to value investments may be impacted by technological issues or errors by pricing services or other third-party service providers.

Roundhill Innovation-100 0DTE Covered Call Strategy ETF | MONEY MARKET FUNDS RISK  
Prospectus [Line Items]

MONEY MARKET FUNDS RISK. The Fund may invest in money market funds. An investment in a money market fund is not a bank deposit and is not insured or guaranteed by any bank, the Federal Deposit Insurance Corporation (“FDIC”) or any other government agency. Although money market funds seek to preserve the value of investments at $1.00 per share, it is possible for the Fund to lose money if shares of money market funds in which it invests fall below $1.00 per share.

Roundhill Innovation-100 0DTE Covered Call Strategy ETF | 0DTE OPTIONS RISK  
Prospectus [Line Items]  
Risk [Text Block]

0DTE OPTIONS RISK. The Fund’s use of zero days to expiration, known as “0DTE” options, presents additional risks. Due to the short time until their expiration, 0DTE options are more sensitive to sudden price movements and market volatility than options with more time until expiration. Because of this, the timing of trades utilizing 0DTE options becomes more critical. Although the Fund intends to enter into 0DTE options trades on market open, or shortly thereafter, even a slight delay in the execution of these trades can significantly impact the outcome of the trade. Such options may also suffer from low liquidity, making it more difficult for the Fund to enter into its positions each morning at desired prices. The bid-ask spreads on 0DTE options can be wider than with traditional options, increasing the Fund’s transaction costs and negatively affecting its returns. Additionally, the proliferation of 0DTE options is relatively new and may therefore be subject to rule changes and operational frictions. To the extent that the OCC enacts new rules relating to 0DTE options that make it impracticable or impossible for the Fund to utilize 0DTE options to effectuate its investment strategy, it may instead utilize options with the shortest remaining maturity available or it may utilize swap agreements to provide the desired exposure.

Roundhill Innovation-100 0DTE Covered Call Strategy ETF | EARLY CLOSE/LATE CLOSE/TRADING HALT RISK

Risk [Text Block]

EARLY CLOSE/LATE CLOSE/TRADING HALT RISK. An exchange or market may close early, close late or issue trading halts on specific securities or financial instruments. As a result, the ability to trade certain securities or financial instruments may be restricted, which may disrupt the Fund’s creation and redemption process, potentially affect the price at which Fund Shares trade in the secondary market, and/or result in the Fund being unable to trade certain securities or financial instruments at all. In these circumstances, the Fund may be unable to rebalance its portfolio, may be unable to accurately price its investments and/or may incur substantial trading losses. If trading in Fund Shares are halted, investors may be temporarily unable to trade Fund Shares.

INNOVATION-100 INDEX RISKS. The Fund will have significant exposure to the Innovation-100 Index through its investments in options that utilize the Innovation-100 Index as the reference asset. Accordingly, the Fund will subject to the risks of the Innovation-100 Index, set forth below.

 

EQUITY SECURITIES RISK. Equity securities are subject to changes in value, and their values may be more volatile than those of other asset classes. Equity securities prices fluctuate for several reasons, including changes in investors’ perceptions of the financial condition of an issuer or the general condition of the relevant equity market, such as market volatility, or when political or economic events affecting an issuer occur. Common stock prices may be particularly sensitive to rising interest rates, as the cost of capital rises and borrowing costs increase. Common stocks generally subject their holders to more risks than preferred stocks and debt securities because common stockholders’ claims are subordinated to those of holders of preferred stocks and debt securities upon the bankruptcy of the issuer.

 

INFORMATION TECHNOLOGY COMPANIES RISK. Information technology companies face intense competition, both domestically and internationally, which may have an adverse effect on profit margins. Like other technology companies, information technology companies may have limited product lines, markets, financial resources or personnel. The products of information technology companies may face obsolescence due to rapid technological developments, frequent new product introduction, unpredictable changes in growth rates and competition for the services of qualified personnel. Companies in the information technology sector are heavily dependent on patent and intellectual property rights. The loss or impairment of these rights may adversely affect the profitability of these companies. Information technology companies are facing increased government and regulatory scrutiny and may be subject to adverse government or regulatory action.

 

ISSUER RISK. The performance of an index depends on the performance of individual securities to which the index has exposure. Changes in the financial condition or credit rating of an issuer of those securities may cause the value of the securities to decline. There is no guarantee that an issuer that paid dividends in the past will continue to do so in the future or will continue paying dividends at the same level.

 

LARGE CAPITALIZATION COMPANIES RISK. Large capitalization companies may be less able than smaller capitalization companies to adapt to changing market conditions. Large capitalization companies may be more mature and subject to more limited growth potential compared with smaller capitalization companies. During different market cycles, the performance of large capitalization companies has trailed the overall performance of the broader securities markets.

 

UNITED STATES RISK. Certain changes in the U.S. economy, such as when the U.S. economy weakens or when its financial markets decline, may have an adverse effect on the securities to which the Fund has exposure.

UNITED STATES GOVERNMENT SECURITIES RISK. The Fund may invest directly in short-term U.S. government securities or in an ETF that holds short-term U.S. government securities. U.S. government securities are subject to interest rate risk but generally do not involve the credit risks associated with investments in other types of debt securities. As a result, the yields available from U.S. government securities are generally lower than the yields available from other debt securities. U.S. government securities are guaranteed only as to the timely payment of interest and the payment of principal when held to maturity.

Risk [Text Block]

NON-DIVERSIFICATION RISK. As a “non-diversified” fund, the Fund may hold a smaller number of portfolio securities than many other funds. To the extent the Fund invests in a relatively small number of issuers, a decline in the market value of a particular security held by the Fund may affect its value more than if it invested in a larger number of issuers. The value of the Fund Shares may be more volatile than the values of shares of more diversified funds.

Roundhill Russell 2000 0DTE Covered Call Strategy ETF | MARKET RISK  
Prospectus [Line Items]  
Risk [Text Block]

MARKET RISK. Market risk is the risk that a particular investment, or Fund Shares in general, may fall in value. Securities are subject to market fluctuations caused by real or perceived adverse economic, political, and regulatory factors or market developments, changes in interest rates, disruptions to trade, impositions of tariffs and perceived trends in securities prices. Fund Shares could decline in value or underperform other investments. In addition, local, regional or global events such as war, acts of terrorism, market manipulation, government defaults, government shutdowns, regulatory actions, political changes, diplomatic developments, the imposition of sanctions and other similar measures, spread of infectious diseases or other public health issues, recessions, natural disasters, or other events could have a significant negative impact on the Fund and its investments. Any of such circumstances could have a materially negative impact on the value of Fund Shares, the liquidity of an investment, and may result in increased market volatility. During any such events, Fund Shares may trade at increased premiums or discounts to their net asset value, the bid/ask spread on Fund Shares may widen and the returns on investment may fluctuate.

Roundhill Russell 2000 0DTE Covered Call Strategy ETF | COVERED CALL STRATEGY RISK  
Prospectus [Line Items]  
Risk [Text Block]

COVERED CALL STRATEGY RISK. A covered call strategy involves writing (selling) covered call options in return for the receipt of premiums. The seller of the option gives up the opportunity to benefit from value increases in the Russell 2000® Index above the strike price of the sold call options, but continues to bear the risk of the Russell 2000® Index price declines. The premiums received from the options may not be sufficient to offset any losses sustained from Russell 2000® Index price declines. Exchanges may suspend the trading of options during periods of abnormal market volatility. Suspension of trading may mean that an option seller is unable to sell options at a time that may be desirable or advantageous to do so.

 

Additionally, the Fund is a “synthetic” covered call strategy, meaning that it derives its long exposure to the Russell 2000® Index from options that utilize the Russell 2000® Index as the reference asset. This synthetic exposure increases the likelihood that the Fund’s returns may not always precisely align with the returns of the Russell 2000® Index.

Roundhill Russell 2000 0DTE Covered Call Strategy ETF | OPTIONS RISK  
Prospectus [Line Items]  
Risk [Text Block]

OPTIONS RISK. The use of options involves investment strategies and risks different from those associated with ordinary portfolio securities transactions and depends on the ability of the Fund’s portfolio managers to forecast market movements correctly. The prices of options are volatile and are influenced by, among other things, actual and anticipated changes in the value of the underlying instrument, or in interest or currency exchange rates, including the anticipated volatility, which in turn are affected by fiscal and monetary policies and by national and international political and economic events. The effective use of options also depends on the Fund’s ability to terminate option positions at times deemed desirable to do so. There is no assurance that the Fund will be able to effect closing transactions at any particular time or at an acceptable price. In addition, there may at times be an imperfect correlation between the movement in values of options and their underlying securities and there may at times not be a liquid secondary market for certain options. Lastly, the trading of options is subject to transaction costs that may impact the Fund’s returns.

Roundhill Russell 2000 0DTE Covered Call Strategy ETF | LIQUIDITY RISK  
Prospectus [Line Items]  
Risk [Text Block]

LIQUIDITY RISK. The market for options may be subject to periods of illiquidity. During such times it may be difficult or impossible to buy or sell a position at the desired price. Market disruptions or volatility can also make it difficult to find a counterparty willing to transact at a reasonable price and sufficient size. Illiquid markets may cause losses, which could be significant. The large size of the positions which the Fund may acquire increases the risk of illiquidity, may make its positions more difficult to liquidate, and may increase the losses incurred while trying to do so. Such large positions also may impact the price of options held by the Fund.

Roundhill Russell 2000 0DTE Covered Call Strategy ETF | ACTIVE MANAGEMENT RISK

ACTIVE MANAGEMENT RISK. The Fund is actively-managed and its performance reflects investment decisions that the Adviser and/or Sub-Adviser makes for the Fund. Such judgments about the Fund’s investments may prove to be incorrect. If the investments selected and the strategies employed by the Fund fail to produce the intended results, the Fund could underperform as compared to other funds with similar investment objectives and/or strategies, or could have negative returns.

ACTIVE MARKET RISK. Although Fund Shares are listed for trading on the Exchange, there can be no assurance that an active trading market for Fund Shares will develop or be maintained. Fund Shares trade on the Exchange at market prices that may be below, at or above the Fund’s net asset value. Securities, including Fund Shares, are subject to market fluctuations and liquidity constraints that may be caused by such factors as economic, political, or regulatory developments, changes in interest rates, and/or perceived trends in securities prices. Fund Shares could decline in value or underperform other investments.

Roundhill Russell 2000 0DTE Covered Call Strategy ETF | CLEARING MEMBER DEFAULT RISK  
Prospectus [Line Items]  
Risk [Text Block]

CLEARING MEMBER DEFAULT RISK. Transactions in some types of derivatives, including the options held by the Fund, are required to be centrally cleared (“cleared derivatives”). In a transaction involving cleared derivatives, the Fund’s counterparty is a clearinghouse, such as the OCC, rather than a bank or broker. Since the Fund is not a member of clearinghouses, and only members of a clearinghouse (“clearing members”) can participate directly in the clearinghouse, the Fund will hold cleared derivatives through accounts at clearing members. With regard its cleared derivatives positions, the Fund will make payments (including margin payments) to, and receive payments from, a clearinghouse through their accounts at clearing members. Customer funds held at a clearing organization in connection with any option contracts are held in a commingled omnibus account and are not identified to the name of the clearing member’s individual customers. As a result, assets deposited by the Fund with any clearing member as margin for its options position may, in certain circumstances, be used to satisfy losses of other clients of the Fund’s clearing member. In addition, although clearing members guarantee performance of their clients’ obligations to the clearinghouse, there is a risk that the assets of the Fund might not be fully protected in the event of the clearing member’s bankruptcy. The Fund is also subject to the risk that a limited number of clearing members are willing to transact on the Fund’s behalf, which heightens the risks associated with a clearing member’s default. If a clearing member defaults, the Fund could lose some or all of the benefits of a transaction entered into by the Fund with the clearing member. The loss of a clearing member for the Fund to transact with could result in increased transaction costs and other operational issues that could impede the Fund’s ability to implement its investment strategy. If the Fund cannot find a clearing member to transact with on the Fund’s behalf, the Fund may be unable to effectively implement its investment strategy.

Roundhill Russell 2000 0DTE Covered Call Strategy ETF | CONCENTRATION RISK

CONCENTRATION RISK. The Fund may be susceptible to an increased risk of loss, including losses due to adverse events that affect the Fund’s investments more than the market as a whole, to the extent that the Fund’s investments are concentrated in the securities and/or other assets of a particular issuer or issuers, country, group of countries, region, market, industry, group of industries, sector, market segment or asset class.

Roundhill Russell 2000 0DTE Covered Call Strategy ETF | CURRENT MARKET CONDITIONS RISK  
Prospectus [Line Items]  
Risk [Text Block]

CURRENT MARKET CONDITIONS RISK. Current market conditions risk is the risk that a particular investment, or Fund Shares in general, may fall in value due to current market conditions. As a means to fight inflation, which remains at elevated levels, the Federal Reserve and certain foreign central banks have raised interest rates; however, the Federal Reserve has recently lowered interest rates and may continue to do so. U.S. regulators have proposed several changes to market and issuer regulations which would directly impact the Fund, and any regulatory changes could adversely impact the Fund’s ability to achieve its investment strategies or make certain investments. Recent and potential future bank failures could result in disruption to the broader banking industry or markets generally and reduce confidence in financial institutions and the economy as a whole, which may also heighten market volatility and reduce liquidity. Additionally, challenges in commercial real estate markets, including rising interest rates, declining valuations and increasing vacancies, could have a broader impact on financial markets. The ongoing adversarial political climate in the United States, as well as political and diplomatic events both domestic and abroad, have and may continue to have an adverse impact the U.S. regulatory landscape, markets and investor behavior, which could have a negative impact on the Fund’s investments and operations. The change in administration resulting from the 2024 United States national elections could result in significant impacts to international trade relations, tax and immigration policies, and other aspects of the national and international political and financial landscape, which could affect, among other things, inflation and the securities markets generally. Other unexpected political, regulatory and diplomatic events within the U.S. and abroad may affect investor and consumer confidence and may adversely impact financial markets and the broader economy. For example, ongoing armed conflicts between Russia and Ukraine in Europe and among Israel, Iran, Hamas and other militant groups in the Middle East, have caused and could continue to cause significant market disruptions and volatility within the markets in Russia, Europe, the Middle East and the United States. The hostilities and sanctions resulting from those hostilities have and could continue to have a significant impact on certain Fund investments as well as Fund performance and liquidity. The economies of the United States and its trading partners, as well as the financial markets generally, may be adversely impacted by trade disputes, including the imposition of tariffs, and other matters. For example, the United States has imposed trade barriers and restrictions on China. In addition, the Chinese government is engaged in a longstanding dispute with Taiwan, continually threatening an invasion. If the political climate between the United States and China does not improve or continues to deteriorate, if China were to attempt invading Taiwan, or if other geopolitical conflicts develop or worsen, economies, markets and individual securities may be adversely affected, and the value of the Fund’s assets may go down. A public health crisis and the ensuing policies enacted by governments and central banks may cause significant volatility and uncertainty in global financial markets, negatively impacting global growth prospects. As the COVID-19 global pandemic illustrated, such events may affect certain geographic regions, countries, sectors and industries more significantly than others. Advancements in technology may also adversely impact markets and the overall performance of the Fund. For instance, the economy may be significantly impacted by the advanced development and increased regulation of artificial intelligence. Additionally, cyber security breaches of both government and non-government entities could have negative impacts on infrastructure and the ability of such entities, including the Fund, to operate properly. These events, and any other future events, may adversely affect the prices and liquidity of the Fund’s portfolio investments and could result in disruptions in the trading markets.

Roundhill Russell 2000 0DTE Covered Call Strategy ETF | CYBERSECURITY RISK  
Prospectus [Line Items]  
Risk [Text Block]

CYBERSECURITY RISK. Failures or breaches of the electronic systems of the Fund, the Fund’s adviser, sub-adviser, distributor and other service providers, market makers, Authorized Participants or the issuers of securities in which the Fund invests have the ability to cause disruptions, negatively impact the Fund’s business operations and/or potentially result in financial losses to the Fund and its shareholders. While the Fund has established business continuity plans and risk management systems seeking to address system breaches or failures, there are inherent limitations in such plans and systems. Furthermore, the Fund cannot control the cybersecurity plans and systems of the Fun’s other service providers, market makers, Authorized Participants or issuers of securities in which the Fund invests.

Roundhill Russell 2000 0DTE Covered Call Strategy ETF | DERIVATIVES RISK  
Prospectus [Line Items]  
Risk [Text Block]

DERIVATIVES RISK. The use of derivative instruments (i.e. options contracts) involves risks different from, or possibly greater than, the risks associated with investing directly in securities and other traditional investments. These risks include: (i) the risk that the counterparty to a derivative transaction may not fulfill its contractual obligations; (ii) risk of mispricing or improper valuation; and (iii) the risk that changes in the value of the derivative may not correlate perfectly with the underlying asset. Derivative prices are highly volatile and may fluctuate substantially during a short period of time. Such prices are influenced by numerous factors that affect the markets, including, but not limited to: changing supply and demand relationships; government programs and policies; national and international political and economic events, changes in interest rates, inflation and deflation and changes in supply and demand relationships. Trading derivative instruments involves risks different from, or possibly greater than, the risks associated with investing directly in securities. Derivative contracts ordinarily have leverage inherent in their terms. The use of leverage may cause the Fund to liquidate portfolio positions when it would not be advantageous to do so in order to satisfy its obligations or to meet regulatory or contractual requirements for derivatives. The use of derivatives can magnify potential for gain or loss and, therefore, amplify the effects of market volatility on the Fund Share price.

Roundhill Russell 2000 0DTE Covered Call Strategy ETF | DISTRIBUTION TAX RISK  
Prospectus [Line Items]  
Risk [Text Block]

DISTRIBUTION TAX RISK. The Fund currently expects to make distributions on a weekly basis. These distributions may exceed the Fund’s income and gains for the Fund’s taxable year. Distributions in excess of the Fund’s current and accumulated earnings and profits will be treated as a return of capital. A return of capital distribution generally will not be taxable but will reduce the shareholder’s cost basis and will result in a higher capital gain or lower capital loss when those Fund Shares on which the distribution was received are sold. Once a Fund shareholder’s cost basis is reduced to zero, further distributions will be treated as capital gain if the Fund shareholder holds Fund Shares as capital assets. Additionally, any capital returned through distributions will be distributed after payment of Fund fees and expenses. Because a portion of the Fund’s distributions will likely consist of return of capital, the Fund may not be an appropriate investment for investors who do not want their principal investment in the Fund to decrease over time or who do not wish to receive return of capital in a given period. In the event that a shareholder purchases Fund Shares shortly before a distribution by the Fund, the entire distribution may be taxable to the shareholder even though a portion of the distribution effectively represents a return of the purchase price.

Roundhill Russell 2000 0DTE Covered Call Strategy ETF | ETF RISK  
Prospectus [Line Items]

ETF RISK. The Fund’s investment in shares of ETFs subjects it to the risks of owning the securities underlying the ETF, as well as the same structural risks faced by an investor purchasing Fund Shares, including Active Management Risk, Active Market Risk, Asset Class Risk, Cybersecurity Risk, Operational Risk and Structural ETF Risk. As a shareholder in another ETF, the Fund bears its proportionate share of the ETF’s expenses, subjecting Fund shareholders to duplicative expenses.

Roundhill Russell 2000 0DTE Covered Call Strategy ETF | FLEX OPTIONS RISK  
Prospectus [Line Items]  
Risk [Text Block]

FLEX OPTIONS RISK. Trading FLEX Options involves risks different from, or possibly greater than, the risks associated with investing directly in securities. The Fund may experience losses from specific FLEX Option positions and certain FLEX Option positions may expire worthless. The FLEX Options are listed on an exchange; however, no one can guarantee that a liquid secondary trading market will exist for the FLEX Options. In the event that trading in the FLEX Options is limited or absent, the value of the Fund’s FLEX Options may decrease. In a less liquid market for the FLEX Options, liquidating the FLEX Options may require the payment of a premium (for written FLEX Options) or acceptance of a discounted price (for purchased FLEX Options) and may take longer to complete. A less liquid trading market may adversely impact the value of the FLEX Options and Fund shares and result in the Fund being unable to achieve its investment objectives. Less liquidity in the trading of the Fund’s FLEX Options could have an impact on the prices paid or received by the Fund for the FLEX Options in connection with creations and redemptions of the Fund Shares. Depending on the nature of this impact to pricing, the Fund may be forced to pay more for redemptions (or receive less for creations) than the price at which it currently values the FLEX Options. Such overpayment or under collection could reduce the Fund’s ability to achieve its investment objectives. Additionally, in a less liquid market for the FLEX Options, the liquidation of a large number of options may more significantly impact the price. A less liquid trading market may adversely impact the value of the FLEX Options and the value of your investment. The trading in FLEX Options may be less deep and liquid than the market for certain other exchange-traded options, non-customized options or other securities.

Roundhill Russell 2000 0DTE Covered Call Strategy ETF | INFLATION RISK

INFLATION RISK. Inflation risk is the risk that the value of assets or income from investments will be less in the future as inflation decreases the value of money. As inflation increases, the present value of the Fund’s assets and distributions may decline. This risk is more prevalent with respect to fixed income securities held by the Fund.

Roundhill Russell 2000 0DTE Covered Call Strategy ETF | OPERATIONAL RISK  
Prospectus [Line Items]  
Risk [Text Block]

OPERATIONAL RISK. The Fund is subject to risks arising from various operational factors, including, but not limited to, human error, processing and communication errors, errors of the Fund’s service providers, counterparties or other third-parties, failed or inadequate processes and technology or systems failures. The Fund relies on third-parties for a range of services, including custody. Any delay or failure relating to engaging or maintaining such service providers may affect the Fund’s ability to meet its investment objectives. Although the Fund and the Adviser seek to reduce these operational risks through controls and procedures, there is no way to completely protect against such risks.

Roundhill Russell 2000 0DTE Covered Call Strategy ETF | SPECIAL TAX RISK  
Prospectus [Line Items]  
Risk [Text Block]

SPECIAL TAX RISK. The Fund intends to invest a portion of its assets in options on indexes. The treatment of such derivatives may, in part, be based upon informal guidance issued by the Internal Revenue Service a number of years ago. Although the Fund believes that the Fund is treating such derivatives consistently with current tax law, if the Internal Revenue Service were to disagree, the Fund could lose its status as a regulated investment company or “RIC.” If the Fund did not qualify as a RIC for any taxable year and certain relief provisions were not available, the Fund’s taxable income would be subject to tax at the Fund level and to a further tax at the shareholder level when such income is distributed. In such event, in order to re-qualify for taxation as a RIC, the Fund might be required to recognize unrealized gains, pay substantial taxes and interest and make certain distributions. This would cause investors to incur higher tax liabilities than they otherwise would have incurred and would have a negative impact on Fund returns. In such event, the Fund’s Board of Trustees may determine to reorganize or close the Fund or materially change the Fund’s investment objectives and strategies.

Roundhill Russell 2000 0DTE Covered Call Strategy ETF | STRUCTURAL ETF RISKS  
Prospectus [Line Items]  
Risk [Text Block]

STRUCTURAL ETF RISKS. The Fund is an ETF. Accordingly, it is subject to certain risks associated with its unique structure.

 

Cash Transactions Risk. The Fund will effect a significant portion of its creations and redemptions for cash, rather than in-kind securities. Paying redemption proceeds in cash rather than through in-kind delivery of portfolio securities may require the Fund to dispose of or sell portfolio securities or other assets at an inopportune time to obtain the cash needed to meet redemption orders. This may cause the Fund to sell a security and recognize a capital gain or loss that might not have been incurred if it had made a redemption in-kind. As a result, the Fund may pay out higher or lower annual capital gains distributions than ETFs that redeem in-kind. The use of cash creations and redemptions may also cause the Fund Shares to trade in the market at greater bid-ask spreads or greater premiums or discounts to the Fund’s net asset value (“NAV”). Furthermore, the Fund may not be able to execute cash transactions for creation and redemption purposes at the same price used to determine the Fund’s NAV. To the extent that the maximum additional charge for creation or redemption transactions is insufficient to cover the execution shortfall, the Fund’s performance could be negatively impacted.

 

Market Participants Risk. Only an Authorized Participant may engage in creation or redemption transactions directly with the Fund, and none of those Authorized Participants is obligated to engage in creation and/or redemption transactions. The Fund has a limited number of institutions that may act as Authorized Participants on an agency basis (i.e., on behalf of other market participants). To the extent that Authorized Participants exit the business or are unable to proceed with creation or redemption orders with respect to the Fund and no other Authorized Participant is able to step forward to create or redeem, Fund Shares may be more likely to trade at a premium or discount to NAV and possibly face trading halts or delisting. The Fund may also rely on a small number of third-party market makers to provide a market for the purchase and sale of Fund Shares but such market makers are under no obligation to do so. Decisions by Authorized Participants or market makers to reduce their role or step away from these activities in times of market stress could inhibit the effectiveness of the arbitrage process in maintaining the relationship between the underlying values of the Fund’s portfolio securities and the Fund’s market price. Any trading halt or other problem relating to the trading activity of these market makers or any issues disrupting the Authorized Participants’ ability to proceed with creation and/or redemption orders could result in a dramatic change in the spread between the Fund’s net asset value and the price at which Fund Shares are trading on the Exchange, which could result in a decrease in value of Fund Shares. This reduced effectiveness could result in Fund Shares trading at a premium or discount to net asset value and also in greater than normal intraday bid-ask spreads Fund Shares.

 

Costs of Buying and Selling Fund Shares. Due to the costs of buying or selling Fund Shares, including brokerage commissions imposed by brokers and bid/ask spreads, frequent trading of Fund Shares may significantly reduce investment results and an investment in Fund Shares may not be advisable for investors who anticipate regularly making small investments.

 

Premium/Discount Risk. As with all ETFs, Fund Shares may be bought and sold in the secondary market at market prices. The trading prices of Fund Shares in the secondary market may differ from the Fund’s daily NAV per share and there may be times when the market price of the shares is more than the NAV per share (premium) or less than the NAV per share (discount). If a shareholder purchases Fund Shares at a time when the market price is at a premium to the NAV or sells Fund Shares at a time when the market price is at a discount to the NAV, the shareholder may pay more for, or receive less than, the underlying value of the Fund Shares, respectively. This risk is heightened in times of market volatility or periods of steep market declines.

 

Trading Risks. Although Fund Shares are listed for trading on the Exchange and may be traded on U.S. exchanges other than the Exchange, there can be no assurance that Fund Shares will trade with any volume, or at all, on any stock exchange. In stressed market conditions, the liquidity of Fund Shares may begin to mirror the liquidity of the Fund’s underlying portfolio holdings, which can be significantly less liquid than Fund Shares. Trading in Fund Shares on the Exchange may be halted due to market conditions or for reasons that, in the view of the Exchange, make trading in Fund Shares inadvisable. In addition, trading in Fund Shares on the Exchange is subject to trading halts caused by extraordinary market volatility pursuant to the Exchange’s “circuit breaker” rules. There can be no assurance that the requirements of the Exchange necessary to maintain the listing of the Fund will continue to be met or will remain unchanged.

Roundhill Russell 2000 0DTE Covered Call Strategy ETF | VALUATION RISK  
Prospectus [Line Items]  
Risk [Text Block]

VALUATION RISK. The Fund may hold securities or other assets that may be valued on the basis of factors other than market quotations. This may occur because the asset or security does not trade on a centralized exchange, or in times of market turmoil or reduced liquidity. There are multiple methods that can be used to value a portfolio holding when market quotations are not readily available. The value established for any portfolio holding at a point in time might differ from what would be produced using a different methodology or if it had been priced using market quotations. Portfolio holdings that are valued using techniques other than market quotations, including “fair valued” assets or securities, may be subject to greater fluctuation in their valuations from one day to the next than if market quotations were used. In addition, there is no assurance that the Fund could sell or close out a portfolio position for the value established for it at any time, and it is possible that the Fund would incur a loss because a portfolio position is sold or closed out at a discount to the valuation established by the Fund at that time. The Fund’s ability to value investments may be impacted by technological issues or errors by pricing services or other third-party service providers.

MONEY MARKET FUNDS RISK. The Fund may invest in money market funds. An investment in a money market fund is not a bank deposit and is not insured or guaranteed by any bank, the Federal Deposit Insurance Corporation (“FDIC”) or any other government agency. Although money market funds seek to preserve the value of investments at $1.00 per share, it is possible for the Fund to lose money if shares of money market funds in which it invests fall below $1.00 per share.

Roundhill Russell 2000 0DTE Covered Call Strategy ETF | EARLY CLOSE/LATE CLOSE/TRADING HALT RISK

Risk [Text Block]

EARLY CLOSE/LATE CLOSE/TRADING HALT RISK. An exchange or market may close early, close late or issue trading halts on specific securities or financial instruments. As a result, the ability to trade certain securities or financial instruments may be restricted, which may disrupt the Fund’s creation and redemption process, potentially affect the price at which Fund Shares trade in the secondary market, and/or result in the Fund being unable to trade certain securities or financial instruments at all. In these circumstances, the Fund may be unable to rebalance its portfolio, may be unable to accurately price its investments and/or may incur substantial trading losses. If trading in Fund Shares are halted, investors may be temporarily unable to trade Fund Shares.

Roundhill Russell 2000 0DTE Covered Call Strategy ETF | UNITED STATES GOVERNMENT SECURITIES RISK  
Prospectus [Line Items]  
Risk [Text Block]

UNITED STATES GOVERNMENT SECURITIES RISK. The Fund may invest directly in short-term U.S. government securities or in an ETF that holds short-term U.S. government securities. U.S. government securities are subject to interest rate risk but generally do not involve the credit risks associated with investments in other types of debt securities. As a result, the yields available from U.S. government securities are generally lower than the yields available from other debt securities. U.S. government securities are guaranteed only as to the timely payment of interest and the payment of principal when held to maturity.

Roundhill Russell 2000 0DTE Covered Call Strategy ETF | 0DTE OPTIONS RISK  
Prospectus [Line Items]  
Risk [Text Block]

0DTE OPTIONS RISK. The Fund’s use of zero days to expiration, known as “0DTE” options, presents additional risks. Due to the short time until their expiration, 0DTE options are more sensitive to sudden price movements and market volatility than options with more time until expiration. Because of this, the timing of trades utilizing 0DTE options becomes more critical. Although the Fund intends to enter into 0DTE options trades on market open, or shortly thereafter, even a slight delay in the execution of these trades can significantly impact the outcome of the trade. Such options may also suffer from low liquidity, making it more difficult for the Fund to enter into its positions each morning at desired prices. The bid-ask spreads on 0DTE options can be wider than with traditional options, increasing the Fund’s transaction costs and negatively affecting its returns. Additionally, the proliferation of 0DTE options is relatively new and may therefore be subject to rule changes and operational frictions. To the extent that the OCC enacts new rules relating to 0DTE options that make it impracticable or impossible for the Fund to utilize 0DTE options to effectuate its investment strategy, it may instead utilize options with the shortest remaining maturity available or it may utilize swap agreements to provide the desired exposure.

RUSSELL 2000® INDEX RISKS. The Fund will have significant exposure to the Russell 2000® Index through its investments in options that utilize the Russell 2000® Index as the reference asset. Accordingly, the Fund will subject to the risks of the Russell 2000® Index, set forth below.

 

EQUITY SECURITIES RISK. Equity securities are subject to changes in value, and their values may be more volatile than those of other asset classes. Equity securities prices fluctuate for several reasons, including changes in investors’ perceptions of the financial condition of an issuer or the general condition of the relevant equity market, such as market volatility, or when political or economic events affecting an issuer occur. Common stock prices may be particularly sensitive to rising interest rates, as the cost of capital rises and borrowing costs increase. Common stocks generally subject their holders to more risks than preferred stocks and debt securities because common stockholders’ claims are subordinated to those of holders of preferred stocks and debt securities upon the bankruptcy of the issuer.

 

ISSUER RISK. The performance of an index depends on the performance of individual securities to which the index has exposure. Changes in the financial condition or credit rating of an issuer of those securities may cause the value of the securities to decline. There is no guarantee that an issuer that paid dividends in the past will continue to do so in the future or will continue paying dividends at the same level.

 

SMALL CAPITALIZATION COMPANIES RISK. Small capitalization companies may be more vulnerable to adverse general market or economic developments, and their securities may be less liquid and may experience greater price volatility than larger, more established companies as a result of several factors, including limited trading volumes, fewer products or financial resources, management inexperience and less publicly available information. Accordingly, such companies are generally subject to greater market risk than larger, more established companies.

 

UNITED STATES RISK. Certain changes in the U.S. economy, such as when the U.S. economy weakens or when its financial markets decline, may have an adverse effect on the securities to which the Fund has exposure.

Risk [Text Block]

NON-DIVERSIFICATION RISK. As a “non-diversified” fund, the Fund may hold a smaller number of portfolio securities than many other funds. To the extent the Fund invests in a relatively small number of issuers, a decline in the market value of a particular security held by the Fund may affect its value more than if it invested in a larger number of issuers. The value of the Fund Shares may be more volatile than the values of shares of more diversified funds.

Roundhill S&P 500® 0DTE Covered Call Strategy ETF | MARKET RISK  
Prospectus [Line Items]  
Risk [Text Block]

MARKET RISK. Market risk is the risk that a particular investment, or Fund Shares in general, may fall in value. Securities are subject to market fluctuations caused by real or perceived adverse economic, political, and regulatory factors or market developments, changes in interest rates, disruptions to trade, impositions of tariffs and perceived trends in securities prices. Fund Shares could decline in value or underperform other investments. In addition, local, regional or global events such as war, acts of terrorism, market manipulation, government defaults, government shutdowns, regulatory actions, political changes, diplomatic developments, the imposition of sanctions and other similar measures, spread of infectious diseases or other public health issues, recessions, natural disasters, or other events could have a significant negative impact on the Fund and its investments. Any of such circumstances could have a materially negative impact on the value of Fund Shares, the liquidity of an investment, and may result in increased market volatility. During any such events, Fund Shares may trade at increased premiums or discounts to their net asset value, the bid/ask spread on Fund Shares may widen and the returns on investment may fluctuate.

Roundhill S&P 500® 0DTE Covered Call Strategy ETF | COVERED CALL STRATEGY RISK  
Prospectus [Line Items]  
Risk [Text Block]

COVERED CALL STRATEGY RISK. A covered call strategy involves writing (selling) covered call options in return for the receipt of premiums. The seller of the option gives up the opportunity to benefit from value increases in the S&P 500® Index above the strike price of the sold call options, but continues to bear the risk of S&P 500® Index price declines. The premiums received from the options may not be sufficient to offset any losses sustained from S&P 500® Index price declines. Exchanges may suspend the trading of options during periods of abnormal market volatility. Suspension of trading may mean that an option seller is unable to sell options at a time that may be desirable or advantageous to do so.

 

Additionally, the Fund is a “synthetic” covered call strategy, meaning that it derives its long exposure to the S&P 500® Index from options that utilize the S&P 500® Index as the reference asset. This synthetic exposure increases the likelihood that the Fund’s returns may not always precisely align with the returns of the S&P 500® Index.

Roundhill S&P 500® 0DTE Covered Call Strategy ETF | OPTIONS RISK  
Prospectus [Line Items]  
Risk [Text Block]

OPTIONS RISK. The use of options involves investment strategies and risks different from those associated with ordinary portfolio securities transactions and depends on the ability of the Fund’s portfolio managers to forecast market movements correctly. The prices of options are volatile and are influenced by, among other things, actual and anticipated changes in the value of the underlying instrument, or in interest or currency exchange rates, including the anticipated volatility, which in turn are affected by fiscal and monetary policies and by national and international political and economic events. The effective use of options also depends on the Fund’s ability to terminate option positions at times deemed desirable to do so. There is no assurance that the Fund will be able to effect closing transactions at any particular time or at an acceptable price. In addition, there may at times be an imperfect correlation between the movement in values of options and their underlying securities and there may at times not be a liquid secondary market for certain options. Lastly, the trading of options is subject to transaction costs that may impact the Fund’s returns.

Roundhill S&P 500® 0DTE Covered Call Strategy ETF | LIQUIDITY RISK  
Prospectus [Line Items]  
Risk [Text Block]

LIQUIDITY RISK. The market for options may be subject to periods of illiquidity. During such times it may be difficult or impossible to buy or sell a position at the desired price. Market disruptions or volatility can also make it difficult to find a counterparty willing to transact at a reasonable price and sufficient size. Illiquid markets may cause losses, which could be significant. The large size of the positions which the Fund may acquire increases the risk of illiquidity, may make its positions more difficult to liquidate, and may increase the losses incurred while trying to do so. Such large positions also may impact the price of options held by the Fund.

Roundhill S&P 500® 0DTE Covered Call Strategy ETF | ACTIVE MANAGEMENT RISK

ACTIVE MANAGEMENT RISK. The Fund is actively-managed and its performance reflects investment decisions that the Adviser and/or Sub-Adviser makes for the Fund. Such judgments about the Fund’s investments may prove to be incorrect. If the investments selected and the strategies employed by the Fund fail to produce the intended results, the Fund could underperform as compared to other funds with similar investment objectives and/or strategies, or could have negative returns.

ACTIVE MARKET RISK. Although Fund Shares are listed for trading on the Exchange, there can be no assurance that an active trading market for Fund Shares will develop or be maintained. Fund Shares trade on the Exchange at market prices that may be below, at or above the Fund’s net asset value. Securities, including Fund Shares, are subject to market fluctuations and liquidity constraints that may be caused by such factors as economic, political, or regulatory developments, changes in interest rates, and/or perceived trends in securities prices. Fund Shares could decline in value or underperform other investments.

Roundhill S&P 500® 0DTE Covered Call Strategy ETF | CLEARING MEMBER DEFAULT RISK  
Prospectus [Line Items]  
Risk [Text Block]

CLEARING MEMBER DEFAULT RISK. Transactions in some types of derivatives, including the options held by the Fund, are required to be centrally cleared (“cleared derivatives”). In a transaction involving cleared derivatives, the Fund’s counterparty is a clearinghouse, such as the OCC, rather than a bank or broker. Since the Fund is not a member of clearinghouses, and only members of a clearinghouse (“clearing members”) can participate directly in the clearinghouse, the Fund will hold cleared derivatives through accounts at clearing members. With regard its cleared derivatives positions, the Fund will make payments (including margin payments) to, and receive payments from, a clearinghouse through their accounts at clearing members. Customer funds held at a clearing organization in connection with any option contracts are held in a commingled omnibus account and are not identified to the name of the clearing member’s individual customers. As a result, assets deposited by the Fund with any clearing member as margin for its options position may, in certain circumstances, be used to satisfy losses of other clients of the Fund’s clearing member. In addition, although clearing members guarantee performance of their clients’ obligations to the clearinghouse, there is a risk that the assets of the Fund might not be fully protected in the event of the clearing member’s bankruptcy. The Fund is also subject to the risk that a limited number of clearing members are willing to transact on the Fund’s behalf, which heightens the risks associated with a clearing member’s default. If a clearing member defaults, the Fund could lose some or all of the benefits of a transaction entered into by the Fund with the clearing member. The loss of a clearing member for the Fund to transact with could result in increased transaction costs and other operational issues that could impede the Fund’s ability to implement its investment strategy. If the Fund cannot find a clearing member to transact with on the Fund’s behalf, the Fund may be unable to effectively implement its investment strategy.

Roundhill S&P 500® 0DTE Covered Call Strategy ETF | CONCENTRATION RISK

CONCENTRATION RISK. The Fund may be susceptible to an increased risk of loss, including losses due to adverse events that affect the Fund’s investments more than the market as a whole, to the extent that the Fund’s investments are concentrated in the securities and/or other assets of a particular issuer or issuers, country, group of countries, region, market, industry, group of industries, sector, market segment or asset class.

Roundhill S&P 500® 0DTE Covered Call Strategy ETF | CURRENT MARKET CONDITIONS RISK  
Prospectus [Line Items]  
Risk [Text Block]

CURRENT MARKET CONDITIONS RISK. Current market conditions risk is the risk that a particular investment, or Fund Shares in general, may fall in value due to current market conditions. As a means to fight inflation, which remains at elevated levels, the Federal Reserve and certain foreign central banks have raised interest rates; however, the Federal Reserve has recently lowered interest rates and may continue to do so. U.S. regulators have proposed several changes to market and issuer regulations which would directly impact the Fund, and any regulatory changes could adversely impact the Fund’s ability to achieve its investment strategies or make certain investments. Recent and potential future bank failures could result in disruption to the broader banking industry or markets generally and reduce confidence in financial institutions and the economy as a whole, which may also heighten market volatility and reduce liquidity. Additionally, challenges in commercial real estate markets, including rising interest rates, declining valuations and increasing vacancies, could have a broader impact on financial markets. The ongoing adversarial political climate in the United States, as well as political and diplomatic events both domestic and abroad, have and may continue to have an adverse impact the U.S. regulatory landscape, markets and investor behavior, which could have a negative impact on the Fund’s investments and operations. The change in administration resulting from the 2024 United States national elections could result in significant impacts to international trade relations, tax and immigration policies, and other aspects of the national and international political and financial landscape, which could affect, among other things, inflation and the securities markets generally. Other unexpected political, regulatory and diplomatic events within the U.S. and abroad may affect investor and consumer confidence and may adversely impact financial markets and the broader economy. For example, ongoing armed conflicts between Russia and Ukraine in Europe and among Israel, Iran, Hamas and other militant groups in the Middle East, have caused and could continue to cause significant market disruptions and volatility within the markets in Russia, Europe, the Middle East and the United States. The hostilities and sanctions resulting from those hostilities have and could continue to have a significant impact on certain Fund investments as well as Fund performance and liquidity. The economies of the United States and its trading partners, as well as the financial markets generally, may be adversely impacted by trade disputes, including the imposition of tariffs, and other matters. For example, the United States has imposed trade barriers and restrictions on China. In addition, the Chinese government is engaged in a longstanding dispute with Taiwan, continually threatening an invasion. If the political climate between the United States and China does not improve or continues to deteriorate, if China were to attempt invading Taiwan, or if other geopolitical conflicts develop or worsen, economies, markets and individual securities may be adversely affected, and the value of the Fund’s assets may go down. A public health crisis and the ensuing policies enacted by governments and central banks may cause significant volatility and uncertainty in global financial markets, negatively impacting global growth prospects. As the COVID-19 global pandemic illustrated, such events may affect certain geographic regions, countries, sectors and industries more significantly than others. Advancements in technology may also adversely impact markets and the overall performance of the Fund. For instance, the economy may be significantly impacted by the advanced development and increased regulation of artificial intelligence. Additionally, cyber security breaches of both government and non-government entities could have negative impacts on infrastructure and the ability of such entities, including the Fund, to operate properly. These events, and any other future events, may adversely affect the prices and liquidity of the Fund’s portfolio investments and could result in disruptions in the trading markets.

Roundhill S&P 500® 0DTE Covered Call Strategy ETF | CYBERSECURITY RISK  
Prospectus [Line Items]  
Risk [Text Block]

CYBERSECURITY RISK. Failures or breaches of the electronic systems of the Fund, the Fund’s adviser, sub-adviser, distributor and other service providers, market makers, Authorized Participants or the issuers of securities in which the Fund invests have the ability to cause disruptions, negatively impact the Fund’s business operations and/or potentially result in financial losses to the Fund and its shareholders. While the Fund has established business continuity plans and risk management systems seeking to address system breaches or failures, there are inherent limitations in such plans and systems. Furthermore, the Fund cannot control the cybersecurity plans and systems of the Fund’s other service providers, market makers, Authorized Participants or issuers of securities in which the Fund invests.

Roundhill S&P 500® 0DTE Covered Call Strategy ETF | DERIVATIVES RISK  
Prospectus [Line Items]  
Risk [Text Block]

DERIVATIVES RISK. The use of derivative instruments (i.e. options contracts) involves risks different from, or possibly greater than, the risks associated with investing directly in securities and other traditional investments. These risks include: (i) the risk that the counterparty to a derivative transaction may not fulfill its contractual obligations; (ii) risk of mispricing or improper valuation; and (iii) the risk that changes in the value of the derivative may not correlate perfectly with the underlying asset. Derivative prices are highly volatile and may fluctuate substantially during a short period of time. Such prices are influenced by numerous factors that affect the markets, including, but not limited to: changing supply and demand relationships; government programs and policies; national and international political and economic events, changes in interest rates, inflation and deflation and changes in supply and demand relationships. Trading derivative instruments involves risks different from, or possibly greater than, the risks associated with investing directly in securities. Derivative contracts ordinarily have leverage inherent in their terms. The use of leverage may cause the Fund to liquidate portfolio positions when it would not be advantageous to do so in order to satisfy its obligations or to meet regulatory or contractual requirements for derivatives. The use of derivatives can magnify potential for gain or loss and, therefore, amplify the effects of market volatility on the Fund Share price.

Roundhill S&P 500® 0DTE Covered Call Strategy ETF | DISTRIBUTION TAX RISK  
Prospectus [Line Items]  
Risk [Text Block]

DISTRIBUTION TAX RISK. The Fund currently expects to make distributions on a weekly basis. These distributions may exceed the Fund’s income and gains for the Fund’s taxable year. Distributions in excess of the Fund’s current and accumulated earnings and profits will be treated as a return of capital. A return of capital distribution generally will not be taxable but will reduce the shareholder’s cost basis and will result in a higher capital gain or lower capital loss when those Fund Shares on which the distribution was received are sold. Once a Fund shareholder’s cost basis is reduced to zero, further distributions will be treated as capital gain if the Fund shareholder holds Fund Shares as capital assets. Additionally, any capital returned through distributions will be distributed after payment of Fund fees and expenses. Because a portion of the Fund’s distributions will likely consist of return of capital, the Fund may not be an appropriate investment for investors who do not want their principal investment in the Fund to decrease over time or who do not wish to receive return of capital in a given period. In the event that a shareholder purchases Fund Shares shortly before a distribution by the Fund, the entire distribution may be taxable to the shareholder even though a portion of the distribution effectively represents a return of the purchase price.

Roundhill S&P 500® 0DTE Covered Call Strategy ETF | ETF RISK

ETF RISK. The Fund’s investment in shares of ETFs subjects it to the risks of owning the securities underlying the ETF, as well as the same structural risks faced by an investor purchasing Fund Shares, including Active Management Risk, Active Market Risk, Asset Class Risk, Cybersecurity Risk, Operational Risk and Structural ETF Risk. As a shareholder in another ETF, the Fund bears its proportionate share of the ETF’s expenses, subjecting Fund shareholders to duplicative expenses.

Roundhill S&P 500® 0DTE Covered Call Strategy ETF | FLEX OPTIONS RISK  
Prospectus [Line Items]  
Risk [Text Block]

FLEX OPTIONS RISK. Trading FLEX Options involves risks different from, or possibly greater than, the risks associated with investing directly in securities. The Fund may experience losses from specific FLEX Option positions and certain FLEX Option positions may expire worthless. The FLEX Options are listed on an exchange; however, no one can guarantee that a liquid secondary trading market will exist for the FLEX Options. In the event that trading in the FLEX Options is limited or absent, the value of the Fund’s FLEX Options may decrease. In a less liquid market for the FLEX Options, liquidating the FLEX Options may require the payment of a premium (for written FLEX Options) or acceptance of a discounted price (for purchased FLEX Options) and may take longer to complete. A less liquid trading market may adversely impact the value of the FLEX Options and Fund shares and result in the Fund being unable to achieve its investment objectives. Less liquidity in the trading of the Fund’s FLEX Options could have an impact on the prices paid or received by the Fund for the FLEX Options in connection with creations and redemptions of the Fund’s Shares. Depending on the nature of this impact to pricing, the Fund may be forced to pay more for redemptions (or receive less for creations) than the price at which it currently values the FLEX Options. Such overpayment or under collection could reduce the Fund’s ability to achieve its investment objectives. Additionally, in a less liquid market for the FLEX Options, the liquidation of a large number of options may more significantly impact the price. A less liquid trading market may adversely impact the value of the FLEX Options and the value of your investment. The trading in FLEX Options may be less deep and liquid than the market for certain other exchange-traded options, non-customized options or other securities.

Roundhill S&P 500® 0DTE Covered Call Strategy ETF | INFLATION RISK

INFLATION RISK. Inflation risk is the risk that the value of assets or income from investments will be less in the future as inflation decreases the value of money. As inflation increases, the present value of the Fund’s assets and distributions may decline. This risk is more prevalent with respect to fixed income securities held by the Fund.

Roundhill S&P 500® 0DTE Covered Call Strategy ETF | OPERATIONAL RISK  
Prospectus [Line Items]

OPERATIONAL RISK. The Fund is subject to risks arising from various operational factors, including, but not limited to, human error, processing and communication errors, errors of the Fund’s service providers, counterparties or other third-parties, failed or inadequate processes and technology or systems failures. The Fund relies on third-parties for a range of services, including custody. Any delay or failure relating to engaging or maintaining such service providers may affect the Fund’s ability to meet its investment objectives. Although the Fund and the Adviser seek to reduce these operational risks through controls and procedures, there is no way to completely protect against such risks.

Roundhill S&P 500® 0DTE Covered Call Strategy ETF | SPECIAL TAX RISK  
Prospectus [Line Items]  
Risk [Text Block]

SPECIAL TAX RISK. The Fund intends to invest a portion of its assets in options on indexes. The treatment of such derivatives may, in part, be based upon informal guidance issued by the Internal Revenue Service a number of years ago. Although the Fund believes that the Fund is treating such derivatives consistently with current tax law, if the Internal Revenue Service were to disagree, the Fund could lose its status as a regulated investment company or “RIC.” If the Fund did not qualify as a RIC for any taxable year and certain relief provisions were not available, the Fund’s taxable income would be subject to tax at the Fund level and to a further tax at the shareholder level when such income is distributed. In such event, in order to re-qualify for taxation as a RIC, the Fund might be required to recognize unrealized gains, pay substantial taxes and interest and make certain distributions. This would cause investors to incur higher tax liabilities than they otherwise would have incurred and would have a negative impact on Fund returns. In such event, the Fund’s Board of Trustees may determine to reorganize or close the Fund or materially change the Fund’s investment objectives and strategies.

Roundhill S&P 500® 0DTE Covered Call Strategy ETF | STRUCTURAL ETF RISKS  
Prospectus [Line Items]  
Risk [Text Block]

STRUCTURAL ETF RISKS. The Fund is an ETF. Accordingly, it is subject to certain risks associated with its unique structure.

 

Cash Transactions Risk. The Fund will effect a significant portion of its creations and redemptions for cash, rather than in-kind securities. Paying redemption proceeds in cash rather than through in-kind delivery of portfolio securities may require the Fund to dispose of or sell portfolio securities or other assets at an inopportune time to obtain the cash needed to meet redemption orders. This may cause the Fund to sell a security and recognize a capital gain or loss that might not have been incurred if it had made a redemption in-kind. As a result, the Fund may pay out higher or lower annual capital gains distributions than ETFs that redeem in-kind. The use of cash creations and redemptions may also cause the Fund Shares to trade in the market at greater bid-ask spreads or greater premiums or discounts to the Fund’s net asset value (“NAV”). Furthermore, the Fund may not be able to execute cash transactions for creation and redemption purposes at the same price used to determine the Fund’s NAV. To the extent that the maximum additional charge for creation or redemption transactions is insufficient to cover the execution shortfall, the Fund’s performance could be negatively impacted.

 

Market Participants Risk. Only an Authorized Participant may engage in creation or redemption transactions directly with the Fund, and none of those Authorized Participants is obligated to engage in creation and/or redemption transactions. The Fund has a limited number of institutions that may act as Authorized Participants on an agency basis (i.e., on behalf of other market participants). To the extent that Authorized Participants exit the business or are unable to proceed with creation or redemption orders with respect to the Fund and no other Authorized Participant is able to step forward to create or redeem, Fund Shares may be more likely to trade at a premium or discount to NAV and possibly face trading halts or delisting. The Fund may also rely on a small number of third-party market makers to provide a market for the purchase and sale of Fund Shares but such market makers are under no obligation to do so. Decisions by Authorized Participants or market makers to reduce their role or step away from these activities in times of market stress could inhibit the effectiveness of the arbitrage process in maintaining the relationship between the underlying values of the Fund’s portfolio securities and the Fund’s market price. Any trading halt or other problem relating to the trading activity of these market makers or any issues disrupting the Authorized Participants’ ability to proceed with creation and/or redemption orders could result in a dramatic change in the spread between the Fund’s net asset value and the price at which Fund Shares are trading on the Exchange, which could result in a decrease in value of Fund Shares. This reduced effectiveness could result in Fund Shares trading at a premium or discount to net asset value and also in greater than normal intraday bid-ask spreads Fund Shares.

 

Costs of Buying and Selling Fund Shares. Due to the costs of buying or selling Fund Shares, including brokerage commissions imposed by brokers and bid/ask spreads, frequent trading of Fund Shares may significantly reduce investment results and an investment in Fund Shares may not be advisable for investors who anticipate regularly making small investments.

 

Premium/Discount Risk. As with all ETFs, Fund Shares may be bought and sold in the secondary market at market prices. The trading prices of Fund Shares in the secondary market may differ from the Fund’s daily NAV per share and there may be times when the market price of the shares is more than the NAV per share (premium) or less than the NAV per share (discount). If a shareholder purchases Fund Shares at a time when the market price is at a premium to the net asset value or sells Fund Shares at a time when the market price is at a discount to the NAV, the shareholder may pay more for, or receive less than, the underlying value of the Fund Shares, respectively. This risk is heightened in times of market volatility or periods of steep market declines.

 

Trading Risks. Although Fund Shares are listed for trading on the Exchange and may be traded on U.S. exchanges other than the Exchange, there can be no assurance that Fund Shares will trade with any volume, or at all, on any stock exchange. In stressed market conditions, the liquidity of Fund Shares may begin to mirror the liquidity of the Fund’s underlying portfolio holdings, which can be significantly less liquid than Fund Shares. Trading in Fund Shares on the Exchange may be halted due to market conditions or for reasons that, in the view of the Exchange, make trading in Fund Shares inadvisable. In addition, trading in Fund Shares on the Exchange is subject to trading halts caused by extraordinary market volatility pursuant to the Exchange’s “circuit breaker” rules. There can be no assurance that the requirements of the Exchange necessary to maintain the listing of the Fund will continue to be met or will remain unchanged.

Roundhill S&P 500® 0DTE Covered Call Strategy ETF | VALUATION RISK  
Prospectus [Line Items]  
Risk [Text Block]

VALUATION RISK. The Fund may hold securities or other assets that may be valued on the basis of factors other than market quotations. This may occur because the asset or security does not trade on a centralized exchange, or in times of market turmoil or reduced liquidity. There are multiple methods that can be used to value a portfolio holding when market quotations are not readily available. The value established for any portfolio holding at a point in time might differ from what would be produced using a different methodology or if it had been priced using market quotations. Portfolio holdings that are valued using techniques other than market quotations, including “fair valued” assets or securities, may be subject to greater fluctuation in their valuations from one day to the next than if market quotations were used. In addition, there is no assurance that the Fund could sell or close out a portfolio position for the value established for it at any time, and it is possible that the Fund would incur a loss because a portfolio position is sold or closed out at a discount to the valuation established by the Fund at that time. The Fund’s ability to value investments may be impacted by technological issues or errors by pricing services or other third-party service providers.

Roundhill S&P 500® 0DTE Covered Call Strategy ETF | MONEY MARKET FUNDS RISK

MONEY MARKET FUNDS RISK. The Fund may invest in money market funds. An investment in a money market fund is not a bank deposit and is not insured or guaranteed by any bank, the Federal Deposit Insurance Corporation (“FDIC”) or any other government agency. Although money market funds seek to preserve the value of investments at $1.00 per share, it is possible for the Fund to lose money if shares of money market funds in which it invests fall below $1.00 per share.

Roundhill S&P 500® 0DTE Covered Call Strategy ETF | 0DTE OPTIONS RISK  
Prospectus [Line Items]  
Risk [Text Block]

0DTE OPTIONS RISK. The Fund’s use of zero days to expiration, known as “0DTE” options, presents additional risks. Due to the short time until their expiration, 0DTE options are more sensitive to sudden price movements and market volatility than options with more time until expiration. Because of this, the timing of trades utilizing 0DTE options becomes more critical. Although the Fund intends to enter into 0DTE options trades on market open, or shortly thereafter, even a slight delay in the execution of these trades can significantly impact the outcome of the trade. Such options may also suffer from low liquidity, making it more difficult for the Fund to enter into its positions each morning at desired prices. The bid-ask spreads on 0DTE options can be wider than with traditional options, increasing the Fund’s transaction costs and negatively affecting its returns. Additionally, the proliferation of 0DTE options is relatively new and may therefore be subject to rule changes and operational frictions. To the extent that the OCC enacts new rules relating to 0DTE options that make it impracticable or impossible for the Fund to utilize 0DTE options to effectuate its investment strategy, it may instead utilize options with the shortest remaining maturity available or it may utilize swap agreements to provide the desired exposure.

Roundhill S&P 500® 0DTE Covered Call Strategy ETF | EARLY CLOSE/LATE CLOSE/TRADING HALT RISK

Risk [Text Block]

EARLY CLOSE/LATE CLOSE/TRADING HALT RISK. An exchange or market may close early, close late or issue trading halts on specific securities or financial instruments. As a result, the ability to trade certain securities or financial instruments may be restricted, which may disrupt the Fund’s creation and redemption process, potentially affect the price at which Fund Shares trade in the secondary market, and/or result in the Fund being unable to trade certain securities or financial instruments at all. In these circumstances, the Fund may be unable to rebalance its portfolio, may be unable to accurately price its investments and/or may incur substantial trading losses. If trading in Fund Shares are halted, investors may be temporarily unable to trade Fund Shares.

Roundhill S&P 500® 0DTE Covered Call Strategy ETF | UNITED STATES GOVERNMENT SECURITIES RISK  
Prospectus [Line Items]  
Risk [Text Block]

UNITED STATES GOVERNMENT SECURITIES RISK. The Fund may invest directly in short-term U.S. government securities or in an ETF that holds short-term U.S. government securities. U.S. government securities are subject to interest rate risk but generally do not involve the credit risks associated with investments in other types of debt securities. As a result, the yields available from U.S. government securities are generally lower than the yields available from other debt securities. U.S. government securities are guaranteed only as to the timely payment of interest and the payment of principal when held to maturity.

Roundhill S&P 500® 0DTE Covered Call Strategy ETF | S&P 500® INDEX RISKS

Risk [Text Block]

S&P 500® INDEX RISKS. The Fund will have significant exposure to the S&P 500® Index through its investments in options that utilize the S&P 500® Index as the reference asset. Accordingly, the Fund will subject to the risks of the S&P 500® Index, set forth below.

 

EQUITY SECURITIES RISK. Equity securities are subject to changes in value, and their values may be more volatile than those of other asset classes. Equity securities prices fluctuate for several reasons, including changes in investors’ perceptions of the financial condition of an issuer or the general condition of the relevant equity market, such as market volatility, or when political or economic events affecting an issuer occur. Common stock prices may be particularly sensitive to rising interest rates, as the cost of capital rises and borrowing costs increase. Common stocks generally subject their holders to more risks than preferred stocks and debt securities because common stockholders’ claims are subordinated to those of holders of preferred stocks and debt securities upon the bankruptcy of the issuer.

 

INFORMATION TECHNOLOGY COMPANIES RISK. Information technology companies face intense competition, both domestically and internationally, which may have an adverse effect on profit margins. Like other technology companies, information technology companies may have limited product lines, markets, financial resources or personnel. The products of information technology companies may face obsolescence due to rapid technological developments, frequent new product introduction, unpredictable changes in growth rates and competition for the services of qualified personnel. Companies in the information technology sector are heavily dependent on patent and intellectual property rights. The loss or impairment of these rights may adversely affect the profitability of these companies. Information technology companies are facing increased government and regulatory scrutiny and may be subject to adverse government or regulatory action.

 

ISSUER RISK. The performance of an index depends on the performance of individual securities to which the index has exposure. Changes in the financial condition or credit rating of an issuer of those securities may cause the value of the securities to decline. There is no guarantee that an issuer that paid dividends in the past will continue to do so in the future or will continue paying dividends at the same level.

 

LARGE CAPITALIZATION COMPANIES RISK. Large capitalization companies may be less able than smaller capitalization companies to adapt to changing market conditions. Large capitalization companies may be more mature and subject to more limited growth potential compared with smaller capitalization companies. During different market cycles, the performance of large capitalization companies has trailed the overall performance of the broader securities markets.

 

UNITED STATES RISK. Certain changes in the U.S. economy, such as when the U.S. economy weakens or when its financial markets decline, may have an adverse effect on the securities to which the Fund has exposure.

NON-DIVERSIFICATION RISK. As a “non-diversified” fund, the Fund may hold a smaller number of portfolio securities than many other funds. To the extent the Fund invests in a relatively small number of issuers, a decline in the market value of a particular security held by the Fund may affect its value more than if it invested in a larger number of issuers. The value of the Fund Shares may be more volatile than the values of shares of more diversified funds.

Risk [Text Block]

MARKET RISK. Market risk is the risk that a particular investment, or Fund Shares in general, may fall in value. Securities are subject to market fluctuations caused by real or perceived adverse economic, political, and regulatory factors or market developments, changes in interest rates, disruptions to trade, impositions of tariffs and perceived trends in securities prices. Fund Shares could decline in value or underperform other investments. In addition, local, regional or global events such as war, acts of terrorism, market manipulation, government defaults, government shutdowns, regulatory actions, political changes, diplomatic developments, the imposition of sanctions and other similar measures, spread of infectious diseases or other public health issues, recessions, natural disasters, or other events could have a significant negative impact on the Fund and its investments. Any of such circumstances could have a materially negative impact on the value of Fund Shares, the liquidity of an investment, and may result in increased market volatility. During any such events, Fund Shares may trade at increased premiums or discounts to their net asset value, the bid/ask spread on Fund Shares may widen and the returns on investment may fluctuate.

ACTIVE MANAGEMENT RISK. The Fund is actively-managed and its performance reflects investment decisions that the Adviser and/or Sub-Adviser makes for the Fund. Such judgments about the Fund’s investments may prove to be incorrect. If the investments selected and the strategies employed by the Fund fail to produce the intended results, the Fund could underperform as compared to other funds with similar investment objectives and/or strategies, or could have negative returns. The Adviser/Sub-Adviser will seek to employ the Fund’s investment strategy regardless of whether there are periods of adverse market, economic, or other conditions and will not seek to take temporary defensive positions during such periods.

ACTIVE MARKET RISK. Although Fund Shares are listed for trading on the Exchange, there can be no assurance that an active trading market for Fund Shares will develop or be maintained. Fund Shares trade on the Exchange at market prices that may be below, at or above the Fund’s net asset value. Securities, including Fund Shares, are subject to market fluctuations and liquidity constraints that may be caused by such factors as economic, political, or regulatory developments, changes in interest rates, and/or perceived trends in securities prices. Fund Shares could decline in value or underperform other investments.

ASSET CLASS RISK. Securities and other assets in the Fund’s portfolio may underperform in comparison to the general financial markets, a particular financial market or other asset classes. In addition, the Fund’s use of FLEX Options to track the performance of the S&P 500® Index may cause the Fund to underperform the return provided by the S&P 500® Index by varying degrees, depending upon market forces.

Roundhill S&P 500® Target 10 Managed Distribution ETF | CLEARING MEMBER DEFAULT RISK  
Prospectus [Line Items]  
Risk [Text Block]

CLEARING MEMBER DEFAULT RISK. Transactions in some types of derivatives, including the options held by the Fund, are required to be centrally cleared (“cleared derivatives”). In a transaction involving cleared derivatives, the Fund’s counterparty is a clearinghouse, such as the OCC, rather than a bank or broker. Since the Fund is not a member of clearinghouses, and only members of a clearinghouse (“clearing members”) can participate directly in the clearinghouse, the Fund will hold cleared derivatives through accounts at clearing members. With regard its cleared derivatives positions, the Fund will make payments (including margin payments) to, and receive payments from, a clearinghouse through their accounts at clearing members. Customer funds held at a clearing organization in connection with any option contracts are held in a commingled omnibus account and are not identified to the name of the clearing member’s individual customers. As a result, assets deposited by the Fund with any clearing member as margin for its options position may, in certain circumstances, be used to satisfy losses of other clients of the Fund’s clearing member. In addition, although clearing members guarantee performance of their clients’ obligations to the clearinghouse, there is a risk that the assets of the Fund might not be fully protected in the event of the clearing member’s bankruptcy. The Fund is also subject to the risk that a limited number of clearing members are willing to transact on the Fund’s behalf, which heightens the risks associated with a clearing member’s default. If a clearing member defaults, the Fund could lose some or all of the benefits of a transaction entered into by the Fund with the clearing member. The loss of a clearing member for the Fund to transact with could result in increased transaction costs and other operational issues that could impede the Fund’s ability to implement its investment strategy. If the Fund cannot find a clearing member to transact with on the Fund’s behalf, the Fund may be unable to effectively implement its investment strategy.

CONCENTRATION RISK. The Fund may be susceptible to an increased risk of loss, including losses due to adverse events that affect the Fund’s investments more than the market as a whole, to the extent that the Fund’s investments are concentrated in the securities and/or other assets of a particular issuer or issuers, country, group of countries, region, market, industry, group of industries, sector, market segment or asset class.

Roundhill S&P 500® Target 10 Managed Distribution ETF | CURRENT MARKET CONDITIONS RISK  
Prospectus [Line Items]  
Risk [Text Block]

CURRENT MARKET CONDITIONS RISK. Current market conditions risk is the risk that a particular investment, or Fund Shares in general, may fall in value due to current market conditions. As a means to fight inflation, which remains at elevated levels, the Federal Reserve and certain foreign central banks have raised interest rates; however, the Federal Reserve has recently lowered interest rates and may continue to do so. U.S. regulators have proposed several changes to market and issuer regulations which would directly impact the Fund, and any regulatory changes could adversely impact the Fund’s ability to achieve its investment strategies or make certain investments. Recent and potential future bank failures could result in disruption to the broader banking industry or markets generally and reduce confidence in financial institutions and the economy as a whole, which may also heighten market volatility and reduce liquidity. Additionally, challenges in commercial real estate markets, including rising interest rates, declining valuations and increasing vacancies, could have a broader impact on financial markets. The ongoing adversarial political climate in the United States, as well as political and diplomatic events both domestic and abroad, have and may continue to have an adverse impact the U.S. regulatory landscape, markets and investor behavior, which could have a negative impact on the Fund’s investments and operations. The change in administration resulting from the 2024 United States national elections could result in significant impacts to international trade relations, tax and immigration policies, and other aspects of the national and international political and financial landscape, which could affect, among other things, inflation and the securities markets generally. Other unexpected political, regulatory and diplomatic events within the U.S. and abroad may affect investor and consumer confidence and may adversely impact financial markets and the broader economy. For example, ongoing armed conflicts between Russia and Ukraine in Europe and among Israel, Iran, Hamas and other militant groups in the Middle East, have caused and could continue to cause significant market disruptions and volatility within the markets in Russia, Europe, the Middle East and the United States. The hostilities and sanctions resulting from those hostilities have and could continue to have a significant impact on certain Fund investments as well as Fund performance and liquidity. The economies of the United States and its trading partners, as well as the financial markets generally, may be adversely impacted by trade disputes, including the imposition of tariffs, and other matters. For example, the United States has imposed trade barriers and restrictions on China. In addition, the Chinese government is engaged in a longstanding dispute with Taiwan, continually threatening an invasion. If the political climate between the United States and China does not improve or continues to deteriorate, if China were to attempt invading Taiwan, or if other geopolitical conflicts develop or worsen, economies, markets and individual securities may be adversely affected, and the value of the Fund’s assets may go down. A public health crisis and the ensuing policies enacted by governments and central banks may cause significant volatility and uncertainty in global financial markets, negatively impacting global growth prospects. As the COVID-19 global pandemic illustrated, such events may affect certain geographic regions, countries, sectors and industries more significantly than others. Advancements in technology may also adversely impact markets and the overall performance of the Fund. For instance, the economy may be significantly impacted by the advanced development and increased regulation of artificial intelligence. Additionally, cyber security breaches of both government and non-government entities could have negative impacts on infrastructure and the ability of such entities, including the Fund, to operate properly. These events, and any other future events, may adversely affect the prices and liquidity of the Fund’s portfolio investments and could result in disruptions in the trading markets.

Roundhill S&P 500® Target 10 Managed Distribution ETF | CYBERSECURITY RISK  
Prospectus [Line Items]  
Risk [Text Block]

CYBERSECURITY RISK. Failures or breaches of the electronic systems of the Fund, the Fund’s adviser, sub-adviser, distributor and other service providers, market makers, Authorized Participants or the issuers of securities in which the Fund invests have the ability to cause disruptions, negatively impact the Fund’s business operations and/or potentially result in financial losses to the Fund and its shareholders. While the Fund has established business continuity plans and risk management systems seeking to address system breaches or failures, there are inherent limitations in such plans and systems. Furthermore, the Fund cannot control the cybersecurity plans and systems of the Fund’s other service providers, market makers, Authorized Participants or issuers of securities in which the Fund invests.

Roundhill S&P 500® Target 10 Managed Distribution ETF | DERIVATIVES RISK  
Prospectus [Line Items]  
Risk [Text Block]

DERIVATIVES RISK. The use of derivative instruments (i.e. options contracts) involves risks different from, or possibly greater than, the risks associated with investing directly in securities and other traditional investments. These risks include: (i) the risk that the counterparty to a derivative transaction may not fulfill its contractual obligations; (ii) risk of mispricing or improper valuation; and (iii) the risk that changes in the value of the derivative may not correlate perfectly with the underlying asset. Derivative prices are highly volatile and may fluctuate substantially during a short period of time. Such prices are influenced by numerous factors that affect the markets, including, but not limited to: changing supply and demand relationships; government programs and policies; national and international political and economic events, changes in interest rates, inflation and deflation and changes in supply and demand relationships. Trading derivative instruments involves risks different from, or possibly greater than, the risks associated with investing directly in securities. Derivative contracts ordinarily have leverage inherent in their terms. The use of leverage may cause the Fund to liquidate portfolio positions when it would not be advantageous to do so in order to satisfy its obligations or to meet regulatory or contractual requirements for derivatives. The use of derivatives can magnify potential for gain or loss and, therefore, amplify the effects of market volatility on the Fund Share price.

Roundhill S&P 500® Target 10 Managed Distribution ETF | DISTRIBUTION TAX RISK  
Prospectus [Line Items]  
Risk [Text Block]

DISTRIBUTION TAX RISK. The Fund currently expects to make distributions on a monthly basis. These distributions are expected and designed to exceed the Fund’s income and gains for the Fund’s taxable year. Distributions in excess of the Fund’s current and accumulated earnings and profits will be treated as a return of capital. The Fund seeks to be managed such that the entirety of the Fund’s distributions will be treated as a return of capital. A return of capital distribution generally will not be taxable currently but will reduce the shareholder's cost basis and will result in a higher capital gain or lower capital loss when those Fund Shares on which the distribution was received are sold. Once a Fund shareholder’s cost basis is reduced to zero, further distributions will be treated as capital gain if the Fund shareholder holds Fund Shares as capital assets. Additionally, any capital returned through distributions will be distributed after payment of Fund fees and expenses. Because a significant portion of the Fund’s distributions will consist of return of capital, the Fund may not be an appropriate investment for investors who do not want their principal investment in the Fund to decrease over time or who do not wish to receive return of capital in a given period.

 

The Fund’s ability to achieve its goal of providing an annualized distribution rate of 10% could be negatively impacted if the Fund’s NAV were to decline, through market movements and distribution payments, in excess of 90% during a calendar year.

 

Additionally, in order to maximize the amount of the Fund’s distribution categorized as return of capital, the Adviser is relying upon the ability to conduct in-kind redemptions of the Fund’s SPY FLEX Options. In the event that the Adviser is unable to do so, the ability of the Adviser to maximize return of capital will be impaired.

 

There is no guarantee that the Fund will be able to manage its income so that all or a majority of its distributions will be return of capital. If the Fund makes a distribution out of the Fund’s earnings and profits shareholders will ordinarily be required to pay tax on the distribution in the year of distribution. A sale of portfolio securities or other assets may generate earnings and profits which may cause some of the Fund’s distributions to be taxable as dividends.

Roundhill S&P 500® Target 10 Managed Distribution ETF | FLEX OPTIONS RISK  
Prospectus [Line Items]  
Risk [Text Block]

FLEX OPTIONS RISK. Trading FLEX Options involves risks different from, or possibly greater than, the risks associated with investing directly in securities. The Fund may experience losses from specific FLEX Option positions and certain FLEX Option positions may expire worthless. The FLEX Options are listed on an exchange; however, no one can guarantee that a liquid secondary trading market will exist for the FLEX Options. In the event that trading in the FLEX Options is limited or absent, the value of the Fund’s FLEX Options may decrease. In a less liquid market for the FLEX Options, liquidating the FLEX Options may require the payment of a premium (for written FLEX Options) or acceptance of a discounted price (for purchased FLEX Options) and may take longer to complete. A less liquid trading market may adversely impact the value of the FLEX Options and Fund Shares and result in the Fund being unable to achieve its investment objectives. Less liquidity in the trading of the Fund’s FLEX Options could have an impact on the prices paid or received by the Fund for the FLEX Options in connection with creations and redemptions of the Fund’s Shares. Depending on the nature of this impact to pricing, the Fund may be forced to pay more for redemptions (or receive less for creations) than the price at which it currently values the FLEX Options. Such overpayment or under collection could reduce the Fund’s ability to achieve its investment objectives. Additionally, in a less liquid market for the FLEX Options, the liquidation of a large number of options may more significantly impact the price. A less liquid trading market may adversely impact the value of the FLEX Options and the value of your investment. The trading in FLEX Options may be less deep and liquid than the market for certain other exchange-traded options, non-customized options or other securities.

Roundhill S&P 500® Target 10 Managed Distribution ETF | INFLATION RISK

INFLATION RISK. Inflation risk is the risk that the value of assets or income from investments will be less in the future as inflation decreases the value of money. As inflation increases, the present value of the Fund’s assets and distributions may decline. This risk is more prevalent with respect to fixed income securities held by the Fund.

Roundhill S&P 500® Target 10 Managed Distribution ETF | OPERATIONAL RISK  
Prospectus [Line Items]

OPERATIONAL RISK. The Fund is subject to risks arising from various operational factors, including, but not limited to, human error, processing and communication errors, errors of the Fund’s service providers, counterparties or other third-parties, failed or inadequate processes and technology or systems failures. The Fund relies on third-parties for a range of services, including custody. Any delay or failure relating to engaging or maintaining such service providers may affect the Fund’s ability to meet its investment objectives. Although the Fund and the Adviser seek to reduce these operational risks through controls and procedures, there is no way to completely protect against such risks.

Roundhill S&P 500® Target 10 Managed Distribution ETF | STRUCTURAL ETF RISKS  
Prospectus [Line Items]  
Risk [Text Block]

STRUCTURAL ETF RISKS. The Fund is an ETF. Accordingly, it is subject to certain risks associated with its unique structure.

 

Market Participants Risk. Only an Authorized Participant may engage in creation or redemption transactions directly with the Fund, and none of those Authorized Participants is obligated to engage in creation and/or redemption transactions. The Fund has a limited number of institutions that may act as Authorized Participants on an agency basis (i.e., on behalf of other market participants). To the extent that Authorized Participants exit the business or are unable to proceed with creation or redemption orders with respect to the Fund and no other Authorized Participant is able to step forward to create or redeem, Fund Shares may be more likely to trade at a premium or discount to NAV and possibly face trading halts or delisting. The Fund may also rely on a small number of third-party market makers to provide a market for the purchase and sale of Fund Shares but such market makers are under no obligation to do so. Decisions by Authorized Participants or market makers to reduce their role or step away from these activities in times of market stress could inhibit the effectiveness of the arbitrage process in maintaining the relationship between the underlying values of the Fund’s portfolio securities and the Fund’s market price. Any trading halt or other problem relating to the trading activity of these market makers or any issues disrupting the Authorized Participants’ ability to proceed with creation and/or redemption orders could result in a dramatic change in the spread between the Fund’s net asset value and the price at which Fund Shares are trading on the Exchange, which could result in a decrease in value of Fund Shares. This reduced effectiveness could result in Fund Shares trading at a premium or discount to net asset value and also in greater than normal intraday bid-ask spreads Fund Shares.

 

Cash Transactions Risk. The Fund may effect a portion of its creations and redemptions for cash, rather than in-kind securities. Paying redemption proceeds in cash rather than through in-kind delivery of portfolio securities may require the Fund to dispose of or sell portfolio securities or other assets at an inopportune time to obtain the cash needed to meet redemption orders. This may cause the Fund to sell a security and recognize a capital gain or loss that might not have been incurred if it had made a redemption in-kind. As a result, the Fund may pay out higher or lower annual capital gains distributions than ETFs that redeem in-kind. The use of cash creations and redemptions may also cause the Fund Shares to trade in the market at greater bid-ask spreads or greater premiums or discounts to the Fund’s NAV. Furthermore, the Fund may not be able to execute cash transactions for creation and redemption purposes at the same price used to determine the Fund’s NAV. To the extent that the maximum additional charge for creation or redemption transactions is insufficient to cover the execution shortfall, the Fund’s performance could be negatively impacted.

 

A sale of portfolio securities or other assets may generate earnings and profits which may cause some of the Fund’s distributions to be taxable as dividends.

 

Costs of Buying and Selling Fund Shares. Due to the costs of buying or selling Fund Shares, including brokerage commissions imposed by brokers and bid/ask spreads, frequent trading of Fund Shares may significantly reduce investment results and an investment in Fund Shares may not be advisable for investors who anticipate regularly making small investments.

 

Premium/Discount Risk. As with all ETFs, Fund Shares may be bought and sold in the secondary market at market prices. The trading prices of Fund Shares in the secondary market may differ from the Fund’s daily NAV per share and there may be times when the market price of the shares is more than the NAV per share (premium) or less than the NAV per share (discount). If a shareholder purchases Fund Shares at a time when the market price is at a premium to the NAV or sells Fund Shares at a time when the market price is at a discount to the NAV, the shareholder may pay more for, or receive less than, the underlying value of the Fund Shares, respectively. This risk is heightened in times of market volatility or periods of steep market declines.

 

Trading Risks. Although Fund Shares are listed for trading on the Exchange and may be traded on U.S. exchanges other than the Exchange, there can be no assurance that Fund Shares will trade with any volume, or at all, on any stock exchange. In stressed market conditions, the liquidity of Fund Shares may begin to mirror the liquidity of the Fund’s underlying portfolio holdings, which can be significantly less liquid than Fund Shares. Trading in Fund Shares on the Exchange may be halted due to market conditions or for reasons that, in the view of the Exchange, make trading in Fund Shares inadvisable. In addition, trading in Fund Shares on the Exchange is subject to trading halts caused by extraordinary market volatility pursuant to the Exchange’s “circuit breaker” rules. There can be no assurance that the requirements of the Exchange necessary to maintain the listing of the Fund will continue to be met or will remain unchanged.

EARLY CLOSE/LATE CLOSE/TRADING HALT RISK. An exchange or market may close early, close late or issue trading halts on specific securities or financial instruments. As a result, the ability to trade certain securities or financial instruments may be restricted, which may disrupt the Fund’s creation and redemption process, potentially affect the price at which Fund Shares trade in the secondary market, and/or result in the Fund being unable to trade certain securities or financial instruments at all. In these circumstances, the Fund may be unable to rebalance its portfolio, may be unable to accurately price its investments and/or may incur substantial trading losses. If trading in Fund Shares are halted, investors may be temporarily unable to trade Fund Shares.

Roundhill S&P 500® Target 10 Managed Distribution ETF | MANAGED PAYOUT RISK  
Prospectus [Line Items]  
Risk [Text Block]

MANAGED PAYOUT RISK. The Fund intends to pay monthly distributions to shareholders based on the NAV of the Fund on the final business day of December each calendar year. Distributions will be paid from Fund assets regardless of the Fund’s performance or the level of dividends, income and capital gains earned by the Fund, and will reduce the amount of assets available for investment by the Fund. If distributions paid by the Fund exceed the Fund’s earnings and profits, distributions of that excess will be treated as a return of capital to the extent of your tax basis in your Fund Shares. In general, a return of capital is not taxable and reduces your basis in Fund Shares, thus reducing any loss or increasing any gain on a subsequent taxable disposition of your Fund Shares. After your basis has been reduced to zero, distributions in excess of the Fund’s earnings and profits will be taxable as gain on the sale or exchange of Fund Shares. Please consult your tax advisor about the tax consequences of an investment in Fund Shares.

 

The targeted annual distribution rate to be paid by the Fund each year is based on the NAV of the Fund on the final business day of December of the prior year. During the first calendar year of Fund operations, the Fund’s target annual distribution rate will be based upon its initial NAV. As a result, the dollar amount of the Fund’s distributions could vary substantially from one year to the next and over time depending on several factors. These factors include, among other things, the NAV of the Fund on the final business day of December, the performance of the financial markets in which the Fund invests, the allocation of Fund assets across different asset classes and investments, the performance of the Fund’s investment strategies, the level of dividends and income earned by the Fund, the level of Fund expenses, the amount and timing of creations and redemptions of Fund Shares and the amount and timing of prior distributions by the Fund. It is also possible for payments to go down substantially from one year to the next. The targeted annual distribution rate is not guaranteed and may be decreased or increased in the future. The actual annual distribution rate paid by the Fund each month or year may be higher or lower than the targeted rate.

 

Insofar as the Fund has net investment income in a given year, such net investment income will be paid out via an additional distribution some or all of which will not be characterized as return of capital.

Roundhill S&P 500® Target 10 Managed Distribution ETF | SPY ETF RISKS  
Prospectus [Line Items]  
Risk [Text Block]

SPY ETF RISKS. The Fund will have significant exposure to the S&P 500® Index and the SPY ETF through its investments in the SPY FLEX Options. Accordingly, the Fund will be subject to the risks of the SPY ETF, set forth below. In addition to these risks, the SPY ETF is also subject to the following risks to which the Fund is also subject, which are described within the section entitled “Principal Risks”: Active Market Risk, Asset Class Risk, Concentration Risk, Cybersecurity Risk, Operational Risk and Structural ETF Risk.

 

EQUITY SECURITIES RISK. Equity securities are subject to changes in value, and their values may be more volatile than those of other asset classes. Equity securities prices fluctuate for several reasons, including changes in investors’ perceptions of the financial condition of an issuer or the general condition of the relevant equity market, such as market volatility, or when political or economic events affecting an issuer occur. Common stock prices may be particularly sensitive to rising interest rates, as the cost of capital rises and borrowing costs increase. Common stocks generally subject their holders to more risks than preferred stocks and debt securities because common stockholders’ claims are subordinated to those of holders of preferred stocks and debt securities upon the bankruptcy of the issuer.

 

INFORMATION TECHNOLOGY COMPANIES RISK. Information technology companies face intense competition, both domestically and internationally, which may have an adverse effect on profit margins. Like other technology companies, information technology companies may have limited product lines, markets, financial resources or personnel. The products of information technology companies may face obsolescence due to rapid technological developments, frequent new product introduction, unpredictable changes in growth rates and competition for the services of qualified personnel. Companies in the information technology sector are heavily dependent on patent and intellectual property rights. The loss or impairment of these rights may adversely affect the profitability of these companies. Information technology companies are facing increased government and regulatory scrutiny and may be subject to adverse government or regulatory action.

 

ISSUER RISK. The performance of an ETF depends on the performance of individual securities to which the ETF has exposure. Changes in the financial condition or credit rating of an issuer of those securities may cause the value of the securities to decline. There is no guarantee that an issuer that paid dividends in the past will continue to do so in the future or will continue paying dividends at the same level.

 

LARGE CAPITALIZATION COMPANIES RISK. Large capitalization companies may be less able than smaller capitalization companies to adapt to changing market conditions. Large capitalization companies may be more mature and subject to more limited growth potential compared with smaller capitalization companies. During different market cycles, the performance of large capitalization companies has trailed the overall performance of the broader securities markets.

 

PASSIVE INVESTMENT RISK. The SPY ETF is not actively managed and therefore would not sell an equity security due to current or projected underperformance of a security, industry or sector, unless that security is removed from the S&P 500® Index. Unlike with an actively managed fund, the fund’s investment adviser does not use techniques or defensive strategies designed to lessen the effects of market volatility or to reduce the impact of periods of market decline. This means that, based on market and economic conditions, the fund’s performance could be lower than other types of funds that may actively shift their portfolio assets to take advantage of market opportunities or to lessen the impact of a market decline.

 

TRACKING ERROR RISK. The SPY ETF is subject to “tracking error,” which is the divergence of an ETF’s performance from that of the index which it seeks to track. Tracking error may occur because of differences between the securities and other instruments held in an ETF’s portfolio and those included in the index, pricing differences, transaction costs incurred by the ETF, the ETF’s holding of uninvested cash, differences in timing of the accrual of or the valuation of dividends or interest received by the ETF or distributions paid to the ETF’s shareholders, the requirements to maintain pass-through tax treatment, portfolio transactions carried out to minimize the distribution of capital gains to shareholders, acceptance of custom baskets, changes to the index or the costs to the ETF of complying with various new or existing regulatory requirements, among other reasons. This risk may be heightened during times of increased market volatility or other unusual market conditions. Tracking error also may result because the ETF incurs fees and expenses, while the index it tracks does not.

 

UNITED STATES RISK. Certain changes in the U.S. economy, such as when the U.S. economy weakens or when its financial markets decline, may have an adverse effect on the securities to which the Fund has exposure.

NON-DIVERSIFICATION RISK. As a “non-diversified” fund, the Fund may hold a smaller number of portfolio securities than many other funds. To the extent the Fund invests in a relatively small number of issuers, a decline in the market value of a particular security held by the Fund may affect its value more than if it invested in a larger number of issuers. The value of the Fund Shares may be more volatile than the values of shares of more diversified funds.

MARKET RISK. Market risk is the risk that a particular investment, or Fund Shares in general, may fall in value. Securities are subject to market fluctuations caused by real or perceived adverse economic, political, and regulatory factors or market developments, changes in interest rates, disruptions to trade, impositions of tariffs and perceived trends in securities prices. Fund Shares could decline in value or underperform other investments. In addition, local, regional or global events such as war, acts of terrorism, market manipulation, government defaults, government shutdowns, regulatory actions, political changes, diplomatic developments, the imposition of sanctions and other similar measures, spread of infectious diseases or other public health issues, recessions, natural disasters, or other events could have a significant negative impact on the Fund and its investments. Any of such circumstances could have a materially negative impact on the value of Fund Shares, the liquidity of an investment, and may result in increased market volatility. During any such events, Fund Shares may trade at increased premiums or discounts to their net asset value, the bid/ask spread on Fund Shares may widen and the returns on investment may fluctuate.

ACTIVE MANAGEMENT RISK. The Fund is actively-managed and its performance reflects investment decisions that the Adviser and/or Sub-Adviser makes for the Fund. Such judgments about the Fund’s investments may prove to be incorrect. If the investments selected and the strategies employed by the Fund fail to produce the intended results, the Fund could underperform as compared to other funds with similar investment objectives and/or strategies, or could have negative returns. The Adviser/Sub-Adviser will seek to employ the Fund’s investment strategy regardless of whether there are periods of adverse market, economic, or other conditions and will not seek to take temporary defensive positions during such periods.

ACTIVE MARKET RISK. Although Fund Shares are listed for trading on the Exchange, there can be no assurance that an active trading market for Fund Shares will develop or be maintained. Fund Shares trade on the Exchange at market prices that may be below, at or above the Fund’s net asset value. Securities, including Fund Shares, are subject to market fluctuations and liquidity constraints that may be caused by such factors as economic, political, or regulatory developments, changes in interest rates, and/or perceived trends in securities prices. Fund Shares could decline in value or underperform other investments.

ASSET CLASS RISK. Securities and other assets in the Fund’s portfolio may underperform in comparison to the general financial markets, a particular financial market or other asset classes. In addition, the Fund’s use of FLEX Options to track the performance of the S&P 500® Index may cause the Fund to underperform the return provided by the S&P 500® Index by varying degrees, depending upon market forces.

Roundhill S&P 500® Target 20 Managed Distribution ETF | CLEARING MEMBER DEFAULT RISK  
Prospectus [Line Items]  
Risk [Text Block]

CLEARING MEMBER DEFAULT RISK. Transactions in some types of derivatives, including the options held by the Fund, are required to be centrally cleared (“cleared derivatives”). In a transaction involving cleared derivatives, the Fund’s counterparty is a clearinghouse, such as the OCC, rather than a bank or broker. Since the Fund is not a member of clearinghouses, and only members of a clearinghouse (“clearing members”) can participate directly in the clearinghouse, the Fund will hold cleared derivatives through accounts at clearing members. With regard its cleared derivatives positions, the Fund will make payments (including margin payments) to, and receive payments from, a clearinghouse through their accounts at clearing members. Customer funds held at a clearing organization in connection with any option contracts are held in a commingled omnibus account and are not identified to the name of the clearing member’s individual customers. As a result, assets deposited by the Fund with any clearing member as margin for its options position may, in certain circumstances, be used to satisfy losses of other clients of the Fund’s clearing member. In addition, although clearing members guarantee performance of their clients’ obligations to the clearinghouse, there is a risk that the assets of the Fund might not be fully protected in the event of the clearing member’s bankruptcy. The Fund is also subject to the risk that a limited number of clearing members are willing to transact on the Fund’s behalf, which heightens the risks associated with a clearing member’s default. If a clearing member defaults, the Fund could lose some or all of the benefits of a transaction entered into by the Fund with the clearing member. The loss of a clearing member for the Fund to transact with could result in increased transaction costs and other operational issues that could impede the Fund’s ability to implement its investment strategy. If the Fund cannot find a clearing member to transact with on the Fund’s behalf, the Fund may be unable to effectively implement its investment strategy.

CONCENTRATION RISK. The Fund may be susceptible to an increased risk of loss, including losses due to adverse events that affect the Fund’s investments more than the market as a whole, to the extent that the Fund’s investments are concentrated in the securities and/or other assets of a particular issuer or issuers, country, group of countries, region, market, industry, group of industries, sector, market segment or asset class.

Roundhill S&P 500® Target 20 Managed Distribution ETF | CURRENT MARKET CONDITIONS RISK  
Prospectus [Line Items]  
Risk [Text Block]

CURRENT MARKET CONDITIONS RISK. Current market conditions risk is the risk that a particular investment, or Fund Shares in general, may fall in value due to current market conditions. As a means to fight inflation, which remains at elevated levels, the Federal Reserve and certain foreign central banks have raised interest rates; however, the Federal Reserve has recently lowered interest rates and may continue to do so. U.S. regulators have proposed several changes to market and issuer regulations which would directly impact the Fund, and any regulatory changes could adversely impact the Fund’s ability to achieve its investment strategies or make certain investments. Recent and potential future bank failures could result in disruption to the broader banking industry or markets generally and reduce confidence in financial institutions and the economy as a whole, which may also heighten market volatility and reduce liquidity. Additionally, challenges in commercial real estate markets, including rising interest rates, declining valuations and increasing vacancies, could have a broader impact on financial markets. The ongoing adversarial political climate in the United States, as well as political and diplomatic events both domestic and abroad, have and may continue to have an adverse impact the U.S. regulatory landscape, markets and investor behavior, which could have a negative impact on the Fund’s investments and operations. The change in administration resulting from the 2024 United States national elections could result in significant impacts to international trade relations, tax and immigration policies, and other aspects of the national and international political and financial landscape, which could affect, among other things, inflation and the securities markets generally. Other unexpected political, regulatory and diplomatic events within the U.S. and abroad may affect investor and consumer confidence and may adversely impact financial markets and the broader economy. For example, ongoing armed conflicts between Russia and Ukraine in Europe and among Israel, Iran, Hamas and other militant groups in the Middle East, have caused and could continue to cause significant market disruptions and volatility within the markets in Russia, Europe, the Middle East and the United States. The hostilities and sanctions resulting from those hostilities have and could continue to have a significant impact on certain Fund investments as well as Fund performance and liquidity. The economies of the United States and its trading partners, as well as the financial markets generally, may be adversely impacted by trade disputes, including the imposition of tariffs, and other matters. For example, the United States has imposed trade barriers and restrictions on China. In addition, the Chinese government is engaged in a longstanding dispute with Taiwan, continually threatening an invasion. If the political climate between the United States and China does not improve or continues to deteriorate, if China were to attempt invading Taiwan, or if other geopolitical conflicts develop or worsen, economies, markets and individual securities may be adversely affected, and the value of the Fund’s assets may go down. A public health crisis and the ensuing policies enacted by governments and central banks may cause significant volatility and uncertainty in global financial markets, negatively impacting global growth prospects. As the COVID-19 global pandemic illustrated, such events may affect certain geographic regions, countries, sectors and industries more significantly than others. Advancements in technology may also adversely impact markets and the overall performance of the Fund. For instance, the economy may be significantly impacted by the advanced development and increased regulation of artificial intelligence. Additionally, cyber security breaches of both government and non-government entities could have negative impacts on infrastructure and the ability of such entities, including the Fund, to operate properly. These events, and any other future events, may adversely affect the prices and liquidity of the Fund’s portfolio investments and could result in disruptions in the trading markets.

CYBERSECURITY RISK. Failures or breaches of the electronic systems of the Fund, the Fund’s adviser, sub-adviser, distributor and other service providers, market makers, Authorized Participants or the issuers of securities in which the Fund invests have the ability to cause disruptions, negatively impact the Fund’s business operations and/or potentially result in financial losses to the Fund and its shareholders. While the Fund has established business continuity plans and risk management systems seeking to address system breaches or failures, there are inherent limitations in such plans and systems. Furthermore, the Fund cannot control the cybersecurity plans and systems of the Fund’s other service providers, market makers, Authorized Participants or issuers of securities in which the Fund invests.

Roundhill S&P 500® Target 20 Managed Distribution ETF | DERIVATIVES RISK  
Prospectus [Line Items]  
Risk [Text Block]

DERIVATIVES RISK. The use of derivative instruments (i.e. options contracts) involves risks different from, or possibly greater than, the risks associated with investing directly in securities and other traditional investments. These risks include: (i) the risk that the counterparty to a derivative transaction may not fulfill its contractual obligations; (ii) risk of mispricing or improper valuation; and (iii) the risk that changes in the value of the derivative may not correlate perfectly with the underlying asset. Derivative prices are highly volatile and may fluctuate substantially during a short period of time. Such prices are influenced by numerous factors that affect the markets, including, but not limited to: changing supply and demand relationships; government programs and policies; national and international political and economic events, changes in interest rates, inflation and deflation and changes in supply and demand relationships. Trading derivative instruments involves risks different from, or possibly greater than, the risks associated with investing directly in securities. Derivative contracts ordinarily have leverage inherent in their terms. The use of leverage may cause the Fund to liquidate portfolio positions when it would not be advantageous to do so in order to satisfy its obligations or to meet regulatory or contractual requirements for derivatives. The use of derivatives can magnify potential for gain or loss and, therefore, amplify the effects of market volatility on the Fund Share price.

Roundhill S&P 500® Target 20 Managed Distribution ETF | DISTRIBUTION TAX RISK  
Prospectus [Line Items]  
Risk [Text Block]

DISTRIBUTION TAX RISK. The Fund currently expects to make distributions on a monthly basis. These distributions are expected and designed to exceed the Fund’s income and gains for the Fund’s taxable year. Distributions in excess of the Fund’s current and accumulated earnings and profits will be treated as a return of capital. The Fund seeks to be managed such that the entirety of the Fund’s distributions will be treated as a return of capital. A return of capital distribution generally will not be taxable currently but will reduce the shareholder's cost basis and will result in a higher capital gain or lower capital loss when those Fund Shares on which the distribution was received are sold. Once a Fund shareholder’s cost basis is reduced to zero, further distributions will be treated as capital gain if the Fund shareholder holds Fund Shares as capital assets. Additionally, any capital returned through distributions will be distributed after payment of Fund fees and expenses. Because a significant portion of the Fund’s distributions will consist of return of capital, the Fund may not be an appropriate investment for investors who do not want their principal investment in the Fund to decrease over time or who do not wish to receive return of capital in a given period.

 

The Fund’s ability to achieve its goal of providing an annualized distribution rate of 20% could be negatively impacted if the Fund’s NAV were to decline, through market movements and distribution payments, in excess of 80% during a calendar year.

 

Additionally, in order to maximize the amount of the Fund’s distribution categorized as return of capital, the Adviser is relying upon the ability to conduct in-kind redemptions of the Fund’s SPY FLEX Options. In the event that the Adviser is unable to do so, the ability of the Adviser to maximize return of capital will be impaired.

 

There is no guarantee that the Fund will be able to manage its income so that all or a majority of its distributions will be return of capital. If the Fund makes a distribution out of the Fund’s earnings and profits shareholders will ordinarily be required to pay tax on the distribution in the year of distribution. A sale of portfolio securities or other assets may generate earnings and profits which may cause some of the Fund’s distributions to be taxable as dividends.

Roundhill S&P 500® Target 20 Managed Distribution ETF | FLEX OPTIONS RISK  
Prospectus [Line Items]  
Risk [Text Block]

FLEX OPTIONS RISK. Trading FLEX Options involves risks different from, or possibly greater than, the risks associated with investing directly in securities. The Fund may experience losses from specific FLEX Option positions and certain FLEX Option positions may expire worthless. The FLEX Options are listed on an exchange; however, no one can guarantee that a liquid secondary trading market will exist for the FLEX Options. In the event that trading in the FLEX Options is limited or absent, the value of the Fund’s FLEX Options may decrease. In a less liquid market for the FLEX Options, liquidating the FLEX Options may require the payment of a premium (for written FLEX Options) or acceptance of a discounted price (for purchased FLEX Options) and may take longer to complete. A less liquid trading market may adversely impact the value of the FLEX Options and Fund Shares and result in the Fund being unable to achieve its investment objectives. Less liquidity in the trading of the Fund’s FLEX Options could have an impact on the prices paid or received by the Fund for the FLEX Options in connection with creations and redemptions of the Fund’s Shares. Depending on the nature of this impact to pricing, the Fund may be forced to pay more for redemptions (or receive less for creations) than the price at which it currently values the FLEX Options. Such overpayment or under collection could reduce the Fund’s ability to achieve its investment objectives. Additionally, in a less liquid market for the FLEX Options, the liquidation of a large number of options may more significantly impact the price. A less liquid trading market may adversely impact the value of the FLEX Options and the value of your investment. The trading in FLEX Options may be less deep and liquid than the market for certain other exchange-traded options, non-customized options or other securities.

INFLATION RISK. Inflation risk is the risk that the value of assets or income from investments will be less in the future as inflation decreases the value of money. As inflation increases, the present value of the Fund’s assets and distributions may decline. This risk is more prevalent with respect to fixed income securities held by the Fund.

Roundhill S&P 500® Target 20 Managed Distribution ETF | OPERATIONAL RISK

OPERATIONAL RISK. The Fund is subject to risks arising from various operational factors, including, but not limited to, human error, processing and communication errors, errors of the Fund’s service providers, counterparties or other third-parties, failed or inadequate processes and technology or systems failures. The Fund relies on third-parties for a range of services, including custody. Any delay or failure relating to engaging or maintaining such service providers may affect the Fund’s ability to meet its investment objectives. Although the Fund and the Adviser seek to reduce these operational risks through controls and procedures, there is no way to completely protect against such risks.

Roundhill S&P 500® Target 20 Managed Distribution ETF | STRUCTURAL ETF RISKS  
Prospectus [Line Items]  
Risk [Text Block]

STRUCTURAL ETF RISKS. The Fund is an ETF. Accordingly, it is subject to certain risks associated with its unique structure.

 

Cash Transactions Risk. The Fund may effect a portion of its creations and redemptions for cash, rather than in-kind securities. Paying redemption proceeds in cash rather than through in-kind delivery of portfolio securities may require the Fund to dispose of or sell portfolio securities or other assets at an inopportune time to obtain the cash needed to meet redemption orders. This may cause the Fund to sell a security and recognize a capital gain or loss that might not have been incurred if it had made a redemption in-kind. As a result, the Fund may pay out higher or lower annual capital gains distributions than ETFs that redeem in-kind. The use of cash creations and redemptions may also cause the Fund Shares to trade in the market at greater bid-ask spreads or greater premiums or discounts to the Fund’s NAV. Furthermore, the Fund may not be able to execute cash transactions for creation and redemption purposes at the same price used to determine the Fund’s NAV. To the extent that the maximum additional charge for creation or redemption transactions is insufficient to cover the execution shortfall, the Fund’s performance could be negatively impacted.

 

A sale of portfolio securities or other assets may generate earnings and profits which may cause some of the Fund’s distributions to be taxable as dividends.

 

Market Participants Risk. Only an Authorized Participant may engage in creation or redemption transactions directly with the Fund, and none of those Authorized Participants is obligated to engage in creation and/or redemption transactions. The Fund has a limited number of institutions that may act as Authorized Participants on an agency basis (i.e., on behalf of other market participants). To the extent that Authorized Participants exit the business or are unable to proceed with creation or redemption orders with respect to the Fund and no other Authorized Participant is able to step forward to create or redeem, Fund Shares may be more likely to trade at a premium or discount to NAV and possibly face trading halts or delisting. The Fund may also rely on a small number of third-party market makers to provide a market for the purchase and sale of Fund Shares but such market makers are under no obligation to do so. Decisions by Authorized Participants or market makers to reduce their role or step away from these activities in times of market stress could inhibit the effectiveness of the arbitrage process in maintaining the relationship between the underlying values of the Fund’s portfolio securities and the Fund’s market price. Any trading halt or other problem relating to the trading activity of these market makers or any issues disrupting the Authorized Participants’ ability to proceed with creation and/or redemption orders could result in a dramatic change in the spread between the Fund’s net asset value and the price at which Fund Shares are trading on the Exchange, which could result in a decrease in value of Fund Shares. This reduced effectiveness could result in Fund Shares trading at a premium or discount to net asset value and also in greater than normal intraday bid-ask spreads Fund Shares.

 

Costs of Buying and Selling Fund Shares. Due to the costs of buying or selling Fund Shares, including brokerage commissions imposed by brokers and bid/ask spreads, frequent trading of Fund Shares may significantly reduce investment results and an investment in Fund Shares may not be advisable for investors who anticipate regularly making small investments.

 

Premium/Discount Risk. As with all ETFs, Fund Shares may be bought and sold in the secondary market at market prices. The trading prices of Fund Shares in the secondary market may differ from the Fund’s daily NAV per share and there may be times when the market price of the shares is more than the NAV per share (premium) or less than the NAV per share (discount). If a shareholder purchases Fund Shares at a time when the market price is at a premium to the NAV or sells Fund Shares at a time when the market price is at a discount to the NAV, the shareholder may pay more for, or receive less than, the underlying value of the Fund Shares, respectively. This risk is heightened in times of market volatility or periods of steep market declines.

 

Trading Risks. Although Fund Shares are listed for trading on the Exchange and may be traded on U.S. exchanges other than the Exchange, there can be no assurance that Fund Shares will trade with any volume, or at all, on any stock exchange. In stressed market conditions, the liquidity of Fund Shares may begin to mirror the liquidity of the Fund’s underlying portfolio holdings, which can be significantly less liquid than Fund Shares. Trading in Fund Shares on the Exchange may be halted due to market conditions or for reasons that, in the view of the Exchange, make trading in Fund Shares inadvisable. In addition, trading in Fund Shares on the Exchange is subject to trading halts caused by extraordinary market volatility pursuant to the Exchange’s “circuit breaker” rules. There can be no assurance that the requirements of the Exchange necessary to maintain the listing of the Fund will continue to be met or will remain unchanged.

Roundhill S&P 500® Target 20 Managed Distribution ETF | EARLY CLOSE/LATE CLOSE/TRADING HALT RISK  
Prospectus [Line Items]  
Risk [Text Block]

EARLY CLOSE/LATE CLOSE/TRADING HALT RISK. An exchange or market may close early, close late or issue trading halts on specific securities or financial instruments. As a result, the ability to trade certain securities or financial instruments may be restricted, which may disrupt the Fund’s creation and redemption process, potentially affect the price at which Fund Shares trade in the secondary market, and/or result in the Fund being unable to trade certain securities or financial instruments at all. In these circumstances, the Fund may be unable to rebalance its portfolio, may be unable to accurately price its investments and/or may incur substantial trading losses. If trading in Fund Shares are halted, investors may be temporarily unable to trade Fund Shares.

Roundhill S&P 500® Target 20 Managed Distribution ETF | MANAGED PAYOUT RISK  
Prospectus [Line Items]  
Risk [Text Block]

MANAGED PAYOUT RISK. The Fund intends to pay monthly distributions to shareholders based on the NAV of the Fund on the final business day of December each calendar year. Distributions will be paid from Fund assets regardless of the Fund’s performance or the level of dividends, income and capital gains earned by the Fund, and will reduce the amount of assets available for investment by the Fund. If distributions paid by the Fund exceed the Fund’s earnings and profits, distributions of that excess will be treated as a return of capital to the extent of your tax basis in your Fund Shares. In general, a return of capital is not taxable and reduces your basis in Fund Shares, thus reducing any loss or increasing any gain on a subsequent taxable disposition of your Fund Shares. After your basis has been reduced to zero, distributions in excess of the Fund’s earnings and profits will be taxable as gain on the sale or exchange of Fund Shares. Please consult your tax advisor about the tax consequences of an investment in Fund Shares.

 

The targeted annual distribution rate to be paid by the Fund each year is based on the NAV of the Fund on the final business day of December of the prior year. During the first calendar year of Fund operations, the Fund’s target annual distribution rate will be based upon its initial NAV. As a result, the dollar amount of the Fund’s distributions could vary substantially from one year to the next and over time depending on several factors. These factors include, among other things, the NAV of the Fund on the final business day of December, the performance of the financial markets in which the Fund invests, the allocation of Fund assets across different asset classes and investments, the performance of the Fund’s investment strategies, the level of dividends and income earned by the Fund, the level of Fund expenses, the amount and timing of creations and redemptions of Fund Shares and the amount and timing of prior distributions by the Fund. It is also possible for payments to go down substantially from one year to the next. The targeted annual distribution rate is not guaranteed and may be decreased or increased in the future. The actual annual distribution rate paid by the Fund each month or year may be higher or lower than the targeted rate.

 

Insofar as the Fund has net investment income in a given year, such net investment income will be paid out via an additional distribution some or all of which will not be characterized as return of capital.

Roundhill S&P 500® Target 20 Managed Distribution ETF | SPY ETF RISKS  
Prospectus [Line Items]  
Risk [Text Block]

SPY ETF RISKS. The Fund will have significant exposure to the S&P 500® Index and the SPY ETF through its investments in the SPY FLEX Options. Accordingly, the Fund will be subject to the risks of the SPY ETF, set forth below. In addition to these risks, the SPY ETF is also subject to the following risks to which the Fund is also subject, which are described within the section entitled “Principal Risks”: Active Market Risk, Asset Class Risk, Concentration Risk, Cybersecurity Risk, Operational Risk and Structural ETF Risk.

 

EQUITY SECURITIES RISK. Equity securities are subject to changes in value, and their values may be more volatile than those of other asset classes. Equity securities prices fluctuate for several reasons, including changes in investors’ perceptions of the financial condition of an issuer or the general condition of the relevant equity market, such as market volatility, or when political or economic events affecting an issuer occur. Common stock prices may be particularly sensitive to rising interest rates, as the cost of capital rises and borrowing costs increase. Common stocks generally subject their holders to more risks than preferred stocks and debt securities because common stockholders’ claims are subordinated to those of holders of preferred stocks and debt securities upon the bankruptcy of the issuer.

 

INFORMATION TECHNOLOGY COMPANIES RISK. Information technology companies face intense competition, both domestically and internationally, which may have an adverse effect on profit margins. Like other technology companies, information technology companies may have limited product lines, markets, financial resources or personnel. The products of information technology companies may face obsolescence due to rapid technological developments, frequent new product introduction, unpredictable changes in growth rates and competition for the services of qualified personnel. Companies in the information technology sector are heavily dependent on patent and intellectual property rights. The loss or impairment of these rights may adversely affect the profitability of these companies. Information technology companies are facing increased government and regulatory scrutiny and may be subject to adverse government or regulatory action.

 

ISSUER RISK. The performance of an ETF depends on the performance of individual securities to which the ETF has exposure. Changes in the financial condition or credit rating of an issuer of those securities may cause the value of the securities to decline. There is no guarantee that an issuer that paid dividends in the past will continue to do so in the future or will continue paying dividends at the same level.

 

LARGE CAPITALIZATION COMPANIES RISK. Large capitalization companies may be less able than smaller capitalization companies to adapt to changing market conditions. Large capitalization companies may be more mature and subject to more limited growth potential compared with smaller capitalization companies. During different market cycles, the performance of large capitalization companies has trailed the overall performance of the broader securities markets.

 

PASSIVE INVESTMENT RISK. The SPY ETF is not actively managed and therefore would not sell an equity security due to current or projected underperformance of a security, industry or sector, unless that security is removed from the S&P 500® Index. Unlike with an actively managed fund, the fund’s investment adviser does not use techniques or defensive strategies designed to lessen the effects of market volatility or to reduce the impact of periods of market decline. This means that, based on market and economic conditions, the fund’s performance could be lower than other types of funds that may actively shift their portfolio assets to take advantage of market opportunities or to lessen the impact of a market decline.

 

TRACKING ERROR RISK. The SPY ETF is subject to “tracking error,” which is the divergence of an ETF’s performance from that of the index which it seeks to track. Tracking error may occur because of differences between the securities and other instruments held in an ETF’s portfolio and those included in the index, pricing differences, transaction costs incurred by the ETF, the ETF’s holding of uninvested cash, differences in timing of the accrual of or the valuation of dividends or interest received by the ETF or distributions paid to the ETF’s shareholders, the requirements to maintain pass-through tax treatment, portfolio transactions carried out to minimize the distribution of capital gains to shareholders, acceptance of custom baskets, changes to the index or the costs to the ETF of complying with various new or existing regulatory requirements, among other reasons. This risk may be heightened during times of increased market volatility or other unusual market conditions. Tracking error also may result because the ETF incurs fees and expenses, while the index it tracks does not.

 

UNITED STATES RISK. Certain changes in the U.S. economy, such as when the U.S. economy weakens or when its financial markets decline, may have an adverse effect on the securities to which the Fund has exposure.

NON-DIVERSIFICATION RISK. As a “non-diversified” fund, the Fund may hold a smaller number of portfolio securities than many other funds. To the extent the Fund invests in a relatively small number of issuers, a decline in the market value of a particular security held by the Fund may affect its value more than if it invested in a larger number of issuers. The value of the Fund Shares may be more volatile than the values of shares of more diversified funds.

MARKET RISK. Market risk is the risk that a particular investment, or Fund Shares in general, may fall in value. Securities are subject to market fluctuations caused by real or perceived adverse economic, political, and regulatory factors or market developments, changes in interest rates, disruptions to trade, impositions of tariffs and perceived trends in securities prices. Fund Shares could decline in value or underperform other investments. In addition, local, regional or global events such as war, acts of terrorism, market manipulation, government defaults, government shutdowns, regulatory actions, political changes, diplomatic developments, the imposition of sanctions and other similar measures, spread of infectious diseases or other public health issues, recessions, natural disasters, or other events could have a significant negative impact on the Fund and its investments. Any of such circumstances could have a materially negative impact on the value of Fund Shares, the liquidity of an investment, and may result in increased market volatility. During any such events, Fund Shares may trade at increased premiums or discounts to their net asset value, the bid/ask spread on Fund Shares may widen and the returns on investment may fluctuate.

If the investments selected and the strategies employed by the Fund fail to produce the intended results, the Fund could underperform as compared to other funds with similar investment objectives and/or strategies, or could have negative returns.

The change in administration resulting from the 2024 United States national elections could result in significant impacts to international trade relations, tax and immigration policies, and other aspects of the national and international political and financial landscape, which could affect, among other things, inflation and the securities markets generally. Other unexpected political, regulatory and diplomatic events within the U.S. and abroad may affect investor and consumer confidence and may adversely impact financial markets and the broader economy. For example, ongoing armed conflicts between Russia and Ukraine in Europe and among Israel, Iran, Hamas and other militant groups in the Middle East, have caused and could continue to cause significant market disruptions and volatility within the markets in Russia, Europe, the Middle East and the United States. The hostilities and sanctions resulting from those hostilities have and could continue to have a significant impact on certain Fund investments as well as Fund performance and liquidity. The economies of the United States and its trading partners, as well as the financial markets generally, may be adversely impacted by trade disputes, including the imposition of tariffs, and other matters. For example, the United States has imposed trade barriers and restrictions on China. In addition, the Chinese government is engaged in a longstanding dispute with Taiwan, continually threatening an invasion. If the political climate between the United States and China does not improve or continues to deteriorate, if China were to attempt invading Taiwan, or if other geopolitical conflicts develop or worsen, economies, markets and individual securities may be adversely affected, and the value of the Fund’s assets may go down.

Risk [Text Block]

DEBT SECURITIES RISK. Investments in debt securities subject the holder to the credit risk of the issuer. Credit risk refers to the possibility that the issuer or other obligor of a security will not be able or willing to make payments of interest and principal when due. Generally, the value of debt securities will change inversely with changes in interest rates. To the extent that interest rates rise, certain underlying obligations may be paid off substantially slower than originally anticipated and the value of those securities may fall sharply. During periods of falling interest rates, the income received by the Fund may decline. If the principal on a debt security is prepaid before expected, the prepayments of principal may have to be reinvested in obligations paying interest at lower rates. Debt securities generally do not trade on a securities exchange making them generally less liquid and more difficult to value than common stock.

Roundhill Weekly T-Bill ETF | DISTRIBUTION TAX RISK  
Prospectus [Line Items]  
Risk [Text Block]

DISTRIBUTION TAX RISK. The Fund currently expects to make distributions on a weekly basis. Such distributions may exceed the Fund’s income and gains for the Fund’s taxable year. Distributions in excess of the Fund’s current and accumulated earnings and profits will be treated as a return of capital. A return of capital distribution generally will not be taxable currently but will reduce the shareholder's cost basis and will result in a higher capital gain or lower capital loss when those Fund Shares on which the distribution was received are sold. Once a Fund shareholder’s cost basis is reduced to zero, further distributions will be treated as capital gain if the Fund shareholder holds Fund Shares as capital assets. Additionally, any capital returned through distributions will be distributed after payment of Fund fees and expenses. Because a portion of the Fund’s distributions will consist of return of capital, the Fund may not be an appropriate investment for investors who do not want their principal investment in the Fund to decrease over time or who do not wish to receive return of capital in a given period.

Roundhill Weekly T-Bill ETF | INFLATION RISK  
Prospectus [Line Items]  
Risk [Text Block]

INFLATION RISK. Inflation risk is the risk that the value of assets or income from investments will be less in the future as inflation decreases the value of money. As inflation increases, the present value of the Fund’s assets and distributions may decline. This risk is more prevalent with respect to fixed income securities held by the Fund.

Roundhill Weekly T-Bill ETF | Interest Rate Risk [Member]  
Prospectus [Line Items]  
Risk [Text Block]

INTEREST RATE RISK. Interest rate risk is the risk that the value of the debt securities in the Fund’s portfolio will decline because of rising market interest rates. Interest rate risk is generally lower for shorter term debt securities and higher for longer-term debt securities. Duration is a reasonably accurate measure of a debt security’s price sensitivity to changes in interest rates and a common measure of interest rate risk. Duration measures a debt security’s expected life on a present value basis, taking into account the debt security’s yield, interest payments and final maturity. In general, duration represents the expected percentage change in the value of a security for an immediate 1% change in interest rates. For example, the price of a debt security with a three-year duration would be expected to drop by approximately 3% in response to a 1% increase in interest rates. Therefore, prices of debt securities with shorter durations tend to be less sensitive to interest rate changes than debt securities with longer durations. As the value of a debt security changes over time, so will its duration.

Roundhill Weekly T-Bill ETF | OPERATIONAL RISK

Risk [Text Block]

OPERATIONAL RISK. The Fund is subject to risks arising from various operational factors, including, but not limited to, human error, processing and communication errors, errors of the Fund’s service providers, counterparties or other third-parties, failed or inadequate processes and technology or systems failures. The Fund relies on third-parties for a range of services, including custody. Any delay or failure relating to engaging or maintaining such service providers may affect the Fund’s ability to meet its investment objective. Although the Fund and the Adviser seek to reduce these operational risks through controls and procedures, there is no way to completely protect against such risks.

Roundhill Weekly T-Bill ETF | STRUCTURAL ETF RISKS  
Prospectus [Line Items]  
Risk [Text Block]

STRUCTURAL ETF RISKS. The Fund is an ETF. Accordingly, it is subject to certain risks associated with its unique structure.

 

Market Participants Risk. Only an Authorized Participant may engage in creation or redemption transactions directly with the Fund, and none of those Authorized Participants is obligated to engage in creation and/or redemption transactions. The Fund has a limited number of institutions that may act as Authorized Participants on an agency basis (i.e., on behalf of other market participants). To the extent that Authorized Participants exit the business or are unable to proceed with creation or redemption orders with respect to the Fund and no other Authorized Participant is able to step forward to create or redeem, Fund Shares may be more likely to trade at a premium or discount to NAV and possibly face trading halts or delisting. The Fund may also rely on a small number of third-party market makers to provide a market for the purchase and sale of Fund Shares but such market makers are under no obligation to do so. Decisions by Authorized Participants or market makers to reduce their role or step away from these activities in times of market stress could inhibit the effectiveness of the arbitrage process in maintaining the relationship between the underlying values of the Fund’s portfolio securities and the Fund’s market price. Any trading halt or other problem relating to the trading activity of these market makers or any issues disrupting the Authorized Participants’ ability to proceed with creation and/or redemption orders could result in a dramatic change in the spread between the Fund’s net asset value and the price at which Fund Shares are trading on the Exchange, which could result in a decrease in value of Fund Shares. This reduced effectiveness could result in Fund Shares trading at a premium or discount to net asset value and also in greater than normal intraday bid-ask spreads Fund Shares.

 

Cash Transactions Risk. The Fund intends to effect a significant portion of its creations and redemptions for cash, rather than in-kind securities. Paying redemption proceeds in cash rather than through in-kind delivery of portfolio securities may require the Fund to dispose of or sell portfolio securities or other assets at an inopportune time to obtain the cash needed to meet redemption orders. This may cause the Fund to sell a security and recognize a capital gain or loss that might not have been incurred if it had made a redemption in-kind. As a result, the Fund may pay out higher or lower annual capital gains distributions than ETFs that redeem in-kind. The use of cash creations and redemptions may also cause the Fund Shares to trade in the market at greater bid-ask spreads or greater premiums or discounts to the Fund’s NAV. Furthermore, the Fund may not be able to execute cash transactions for creation and redemption purposes at the same price used to determine the Fund’s NAV. To the extent that the maximum additional charge for creation or redemption transactions is insufficient to cover the execution shortfall, the Fund’s performance could be negatively impacted.

 

Active Market Risk. Although Fund Shares are listed for trading on the Exchange, there can be no assurance that an active trading market for Fund Shares will develop or be maintained. Fund Shares trade on the Exchange at market prices that may be below, at or above the Fund’s net asset value. Securities, including Fund Shares, are subject to market fluctuations and liquidity constraints that may be caused by such factors as economic, political, or regulatory developments, changes in interest rates, and/or perceived trends in securities prices. Fund Shares could decline in value or underperform other investments.

 

Costs of Buying and Selling Fund Shares. Due to the costs of buying or selling Fund Shares, including brokerage commissions imposed by brokers and bid/ask spreads, frequent trading of Fund Shares may significantly reduce investment results and an investment in Fund Shares may not be advisable for investors who anticipate regularly making small investments.

 

Premium/Discount Risk. As with all ETFs, Fund Shares may be bought and sold in the secondary market at market prices. The trading prices of Fund Shares in the secondary market may differ from the Fund’s daily net asset value per Fund Share and there may be times when the market price of Fund Shares is more than the net asset value per share (premium) or less than the net asset value per Fund Share (discount). If a shareholder purchases Fund Shares at a time when the market price is at a premium to the net asset value or sells Fund Shares at a time when the market price is at a discount to the net asset value, the shareholder may pay more for, or receive less than, the underlying value of the Fund Shares, respectively. This risk is heightened in times of market volatility or periods of steep market declines.

 

Trading Risks. Although Fund Shares are listed for trading on the Exchange and may be traded on U.S. exchanges other than the Exchange, there can be no assurance that Fund Shares will trade with any volume, or at all, on any stock exchange. In stressed market conditions, the liquidity of Fund Shares may begin to mirror the liquidity of the Fund’s underlying portfolio holdings, which can be significantly less liquid than Fund Shares. Trading in Fund Shares on the Exchange may be halted due to market conditions or for reasons that, in the view of the Exchange, make trading in Fund Shares inadvisable. In addition, trading in Fund Shares on the Exchange is subject to trading halts caused by extraordinary market volatility pursuant to the Exchange’s “circuit breaker” rules. There can be no assurance that the requirements of the Exchange necessary to maintain the listing of the Fund will continue to be met or will remain unchanged.

Roundhill Weekly T-Bill ETF | U.S. GOVERNMENT SECURITIES RISK  
Prospectus [Line Items]  
Risk [Text Block]

U.S. GOVERNMENT SECURITIES RISK. U.S. government securities, such as T-Bills, are subject to interest rate risk but generally do not involve the credit risks associated with investments in other types of debt securities, as such securities are backed by the full faith and credit of the U.S. government. As a result, the yields available from U.S. government securities are generally lower than the yields available from other debt securities. U.S. government securities are guaranteed only as to the timely payment of interest and the payment of principal when held to maturity.

Roundhill Weekly T-Bill ETF | LARGE SHAREHOLDER RISK  
Prospectus [Line Items]  
Risk [Text Block]

LARGE SHAREHOLDER RISK. Certain shareholders, including affiliated funds advised by the Adviser, may from time to time own a significant portion of the Fund’s shares. In addition, a third-party investor, the Adviser or an affiliate of the Adviser (“Affiliate”), an authorized participant, a market maker, or another entity may invest in the Fund and hold its investment for a limited period solely to facilitate the commencement of the Fund or to help the Fund achieve a specified size or scale. There can be no assurance that any large shareholder will not redeem its investment, that the size of the Fund will be maintained at such levels, or that the Fund will continue to meet applicable listing requirements. Redemptions by large shareholders could have a significant negative impact on the Fund. In addition, transactions by large shareholders may account for a large percentage of the trading volume on the Fund’s listing exchange and may, therefore, have a material upward or downward effect on the market price of the shares.

 

To the extent that a significant percentage of the Fund’s shares are owned or controlled by a small number of account shareholders (or a single account shareholder), including funds or accounts over which the Adviser or an Affiliate has investment discretion, the Fund is subject to the risk that those shareholders may purchase or redeem Fund shares in significant amounts rapidly or unexpectedly, including as a result of an asset allocation decision made by the Adviser or an Affiliate. This may adversely affect the Fund’s performance if the Adviser is forced to sell portfolio securities or invest cash when it would not otherwise choose to do so. Redemptions of a large number of shares may affect the liquidity of the Fund’s portfolio, increase the Fund’s transaction costs, and accelerate the realization of taxable income and/or gains. In addition, a large redemption could result in the Fund’s current expenses being allocated over a smaller asset base, leading to an increase in the Fund’s gross expense ratio. Large purchases of the Fund’s shares may also adversely affect the Fund’s performance to the extent that the Fund is delayed in investing new cash or otherwise maintains a larger cash position than it ordinarily would, particularly if the Fund accepts cash for an order for the purchase of creation units of the Fund’s shares.

NON-DIVERSIFICATION RISK. As a “non-diversified” fund, the Fund may hold a smaller number of portfolio securities than many other funds. To the extent the Fund invests in a relatively small number of issuers, a decline in the market value of a particular security held by the Fund may affect its value more than if it invested in a larger number of issuers. The value of the Fund Shares may be more volatile than the values of shares of more diversified funds.

Roundhill Uranium ETF | MARKET RISK  
Prospectus [Line Items]  
Risk [Text Block]

MARKET RISK. Market risk is the risk that a particular investment, or Fund Shares in general, may fall in value. Securities are subject to market fluctuations caused by real or perceived adverse economic, political, and regulatory factors or market developments, changes in interest rates, disruptions to trade, impositions of tariffs and perceived trends in securities prices. Fund Shares could decline in value or underperform other investments. In addition, local, regional or global events such as war, acts of terrorism, market manipulation, government defaults, government shutdowns, regulatory actions, political changes, diplomatic developments, the imposition of sanctions and other similar measures, spread of infectious diseases or other public health issues, recessions, natural disasters, or other events could have a significant negative impact on the Fund and its investments. Any of such circumstances could have a materially negative impact on the value of Fund Shares, the liquidity of an investment, and may result in increased market volatility. During any such events, Fund Shares may trade at increased premiums or discounts to their net asset value, the bid/ask spread on Fund Shares may widen and the returns on investment may fluctuate.

Roundhill Uranium ETF | LIQUIDITY RISK  
Prospectus [Line Items]  
Risk [Text Block]

LIQUIDITY RISK. The Fund’s swap agreements trade over-the-counter, in limited volume and generally lack an active trading market. Accordingly, the Fund may not be able to sell or close out of such investments at favorable times or prices (or at all), or at the prices approximating those at which the Fund currently values them. Illiquid securities may trade at a discount from comparable, more liquid investments and may be subject to wide fluctuations in market value.

Roundhill Uranium ETF | ACTIVE MANAGEMENT RISK  
Prospectus [Line Items]

ACTIVE MANAGEMENT RISK. The Fund is actively-managed and its performance reflects investment decisions that the Adviser and/or Sub-Adviser makes for the Fund. Such judgments about the Fund’s investments may prove to be incorrect. If the investments selected and the strategies employed by the Fund fail to produce the intended results, the Fund could underperform as compared to other funds with similar investment objectives and/or strategies, or could have negative returns.

CONCENTRATION RISK. The Fund may be susceptible to an increased risk of loss, including losses due to adverse events that affect the Fund’s investments more than the market as a whole, to the extent that the Fund’s investments are concentrated in investments that provide exposure to uranium.

Roundhill Uranium ETF | COUNTERPARTY RISK  
Prospectus [Line Items]  
Risk [Text Block]

COUNTERPARTY RISK. Any swap agreements utilized by the Fund will be subject to counterparty risk between the Fund and its swap counterparties. Fund transactions involving a counterparty are subject to the risk that the counterparty will not fulfill its obligation to the Fund. Counterparty risk may arise because of the counterparty’s financial condition (i.e., financial difficulties, bankruptcy, or insolvency), market activities and developments, or other reasons, whether foreseen or not. A counterparty’s inability to fulfill its obligation may result in significant financial loss to the Fund. The Fund may be unable to recover its investment from the counterparty or may obtain a limited recovery, and/or recovery may be delayed.

Roundhill Uranium ETF | CYBERSECURITY RISK  
Prospectus [Line Items]  
Risk [Text Block]

CYBERSECURITY RISK. Failures or breaches of the electronic systems of the Fund, the Fund’s adviser, sub-adviser, distributor, and other service providers, market makers, Authorized Participants or the issuers of securities in which the Fund invests have the ability to cause disruptions, negatively impact the Fund’s business operations and/or potentially result in financial losses to the Fund and its shareholders. While the Fund has established business continuity plans and risk management systems seeking to address system breaches or failures, there are inherent limitations in such plans and systems. Furthermore, the Fund cannot control the cybersecurity plans and systems of the Fund’s other service providers, market makers, Authorized Participants or issuers of securities in which the Fund invests.

Roundhill Uranium ETF | DEBT SECURITIES RISK  
Prospectus [Line Items]  
Risk [Text Block]

DEBT SECURITIES RISK. The Fund invests in debt securities. Investments in debt securities subject the holder to the credit risk of the issuer. Credit risk refers to the possibility that the issuer or other obligor of a security will not be able or willing to make payments of interest and principal when due. Generally, the value of debt securities will change inversely with changes in interest rates. To the extent that interest rates rise, certain underlying obligations may be paid off substantially slower than originally anticipated and the value of those securities may fall sharply. During periods of falling interest rates, the income received by an underlying fund may decline. If the principal on a debt security is prepaid before expected, the prepayments of principal may have to be reinvested in obligations paying interest at lower rates. Debt securities generally do not trade on a securities exchange making them generally less liquid and more difficult to value than common stock.

Roundhill Uranium ETF | DERIVATIVES RISK  
Prospectus [Line Items]  
Risk [Text Block]

DERIVATIVES RISK. The use of derivative instruments (i.e. swap agreements) involves risks different from, or possibly greater than, the risks associated with investing directly in securities and other traditional investments. These risks include: (i) the risk that the counterparty to a derivative transaction may not fulfill its contractual obligations; (ii) risk of mispricing or improper valuation; and (iii) the risk that changes in the value of the derivative may not correlate perfectly with the underlying asset. Derivative prices are highly volatile and may fluctuate substantially during a short period of time. Such prices are influenced by numerous factors that affect the markets, including, but not limited to: changing supply and demand relationships; government programs and policies; national and international political and economic events, changes in interest rates, inflation and deflation and changes in supply and demand relationships. Trading derivative instruments involves risks different from, or possibly greater than, the risks associated with investing directly in securities. Derivative contracts ordinarily have leverage inherent in their terms. The use of leverage may cause the Fund to liquidate portfolio positions when it would not be advantageous to do so in order to satisfy its obligations or to meet regulatory or contractual requirements for derivatives. The use of derivatives can magnify potential for gain or loss and, therefore, amplify the effects of market volatility on the Fund Share price.

Roundhill Uranium ETF | OPERATIONAL RISK

OPERATIONAL RISK. The Fund is subject to risks arising from various operational factors, including, but not limited to, human error, processing and communication errors, errors of the Fund’s service providers, counterparties or other third-parties, failed or inadequate processes and technology or systems failures. The Fund relies on third-parties for a range of services, including custody. Any delay or failure relating to engaging or maintaining such service providers may affect the Fund’s ability to meet its investment objective. Although the Fund and the Adviser seek to reduce these operational risks through controls and procedures, there is no way to completely protect against such risks.

Roundhill Uranium ETF | SPECIAL TAX RISK  
Prospectus [Line Items]  
Risk [Text Block]

SPECIAL TAX RISK. The Fund intends to elect and to qualify each year to be treated as a RIC under Subchapter M of the Code. As a RIC, the Fund will not be subject to U.S. federal income tax on the portion of its net investment income and net capital gain that it distributes to shareholders, provided that it satisfies certain requirements of the Code. If the Fund does not qualify as a RIC for any taxable year and certain relief provisions are not available, the Fund’s taxable income will be subject to tax at the Fund level and to a further tax at the shareholder level when such income is distributed. Additionally, buying securities shortly before the record date for a taxable dividend or capital gain distribution is commonly known as “buying the dividend.” In the event a shareholder purchases Fund Shares shortly before such a distribution, the entire distribution may be taxable to the shareholder even though a portion of the distribution effectively represents a return of the purchase price. To comply with the asset diversification test applicable to a RIC, the Fund will limit its investments in the Subsidiary to 25% of the Fund’s total assets at the end of each quarter. The investment strategy of the Fund may cause the Fund to hold more than 25% of the Fund’s total assets in investments in the Subsidiary the majority of the time. The Fund intends to manage the exposure to the Subsidiary so that the Fund’s investments in the Subsidiary do not exceed 25% of the total assets at the end of any quarter. If the Fund’s investments in the Subsidiary were to exceed 25% of the Fund’s total assets at the end of a tax quarter, the Fund, generally, has a grace period to cure such lack of compliance. If the Fund fails to timely cure, it may no longer be eligible to be treated as a RIC.

U.S. GOVERNMENT SECURITIES RISK. The Fund may invest in short-term U.S. government securities to collateralize its swap agreements. U.S. government securities are subject to interest rate risk but generally do not involve the credit risks associated with investments in other types of debt securities. As a result, the yields available from U.S. government securities are generally lower than the yields available from other debt securities. U.S. government securities are guaranteed only as to the timely payment of interest and the payment of principal when held to maturity.

Roundhill Uranium ETF | VALUATION RISK  
Prospectus [Line Items]  
Risk [Text Block]

VALUATION RISK. The Fund may hold securities or other assets (such as swap agreements) that may be valued on the basis of factors other than market quotations. This may occur because the asset or security does not trade on a centralized exchange, or in times of market turmoil or reduced liquidity. There are multiple methods that can be used to value a portfolio holding when market quotations are not readily available. The value established for any portfolio holding at a point in time might differ from what would be produced using a different methodology or if it had been priced using market quotations. Portfolio holdings that are valued using techniques other than market quotations, including “fair valued” assets or securities, may be subject to greater fluctuation in their valuations from one day to the next than if market quotations were used. In addition, there is no assurance that the Fund could sell or close out a portfolio position for the value established for it at any time, and it is possible that the Fund would incur a loss because a portfolio position is sold or closed out at a discount to the valuation established by the Fund at that time. The Fund’s ability to value investments may be impacted by technological issues or errors by pricing services or other third-party service providers.

Roundhill Uranium ETF | CURRENCY RISK  
Prospectus [Line Items]

CURRENCY RISK. Changes in currency exchange rates affect the value of investments denominated in a foreign currency, and therefore the value of such investments in the Fund’s portfolio. The Fund’s net asset value could decline if a currency to which the Fund has exposure depreciates against the U.S. dollar or if there are delays or limits on repatriation of such currency. Currency exchange rates can be very volatile and can change quickly and unpredictably. As a result, the value of an investment in the Fund may change quickly and without warning.

Roundhill Uranium ETF | EQUITY SECURITIES RISK  
Prospectus [Line Items]  
Risk [Text Block]

EQUITY SECURITIES RISK. Equity securities are subject to changes in value, and their values may be more volatile than those of other asset classes. Equity securities prices fluctuate for several reasons, including changes in investors’ perceptions of the financial condition of an issuer or the general condition of the relevant equity market, such as market volatility, or when political or economic events affecting an issuer occur. Common stock prices may be particularly sensitive to rising interest rates, as the cost of capital rises and borrowing costs increase. Common stocks generally subject their holders to more risks than preferred stocks and debt securities because common stockholders’ claims are subordinated to those of holders of preferred stocks and debt securities upon the bankruptcy of the issuer.

Roundhill Uranium ETF | MONEY MARKET FUNDS RISK

MONEY MARKET FUNDS RISK. The Fund may invest in money market funds to collateralize its swap agreements and forwards contracts. An investment in a money market fund is not a bank deposit and is not insured or guaranteed by any bank, the Federal Deposit Insurance Corporation (“FDIC”) or any other government agency. Although money market funds seek to preserve the value of investments at $1.00 per share, it is possible for the Fund to lose money if shares of money market funds in which it invests fall below $1.00 per share.

Roundhill Uranium ETF | NON-U.S. SECURITIES RISK  
Prospectus [Line Items]  
Risk [Text Block]

NON-U.S. SECURITIES RISK. Non-U.S. securities are subject to higher volatility than securities of domestic issuers due to possible adverse political, social or economic developments, restrictions on foreign investment or exchange of securities, capital controls, lack of liquidity, currency exchange rates, excessive taxation, government seizure of assets, the imposition of sanctions by foreign governments, different legal or accounting standards, and less government supervision and regulation of securities exchanges in foreign countries.

Roundhill Uranium ETF | SWAP AGREEMENTS RISK  
Prospectus [Line Items]  
Risk [Text Block]

SWAP AGREEMENTS RISK. The Fund will utilize swap agreements to derive its exposure to the price of uranium. Swap agreements may involve greater risks than direct investment in securities as they may be leveraged and are subject to credit risk, counterparty risk and valuation risk. A swap agreement could result in losses if the underlying reference or asset does not perform as anticipated. In addition, many swaps trade over-the-counter and may be considered illiquid. It may not be possible for the Fund to liquidate a swap position at an advantageous time or price, which may result in significant losses.

Roundhill Uranium ETF | URANIUM RISK  
Prospectus [Line Items]  
Risk [Text Block]

URANIUM RISK. While the Fund does not invest directly in uranium, it will have significant exposure to uranium as a result of derivatives (such as swap agreements) that utilize Spot Uranium, Uranium Companies or Uranium Trusts as the reference asset. Accordingly, risks relating to uranium constitute principal risks to the Fund. Such risks relating to uranium are set forth below.

 

MARKET AND PRICE VOLATILITY RISK. Uranium prices are highly volatile due to the interplay of supply and demand dynamics, geopolitical developments, and regulatory changes. The uranium market is relatively small and concentrated, with a limited number of producers and suppliers. As a result, the price of uranium can experience significant fluctuations in response to even minor changes in market conditions, such as shifts in nuclear energy policies, changes in reactor demand, or disruptions in the mining or refining processes.

 

REGULATORY AND POLITICAL RISK. Uranium is a heavily regulated commodity due to its use in nuclear energy and potential for nuclear proliferation. Changes in government regulations, international treaties, or geopolitical tensions can significantly impact uranium production, distribution, and consumption. Any tightening of safety, environmental, or export regulations could constrain supply, while changes in nuclear energy policies, such as the adoption of or withdrawal from nuclear power, could drastically affect demand.

 

SUPPLY CHAIN RISK. The uranium supply chain is geographically concentrated, with major production coming from a few countries such as Kazakhstan, Canada and Australia. This concentration exposes the market to risks of supply disruptions due to political instability, labor disputes or natural disasters in these regions. Additionally, uranium mining and refining are capital-intensive processes with long lead times, making it challenging to quickly respond to shifts in market demand.

 

ENVIRONMENTAL AND OPERATIONAL RISK. Uranium mining and processing involve significant environmental and social challenges, including radioactive contamination, water usage, land use conflicts and waste management. Stricter environmental regulations or increased community opposition could delay or halt mining operations, affecting supply. Operational risks such as equipment failure, accidents or unexpected geological conditions can also disrupt production.

 

NUCLEAR ENERGY DEMAND RISK. The demand for uranium is closely tied to the nuclear energy industry, which faces its own set of risks, including competition from renewable energy sources, public perception, and catastrophic incidents (e.g., Fukushima disaster). A decline in the construction of new nuclear reactors or the decommissioning of existing reactors can lead to reduced demand for uranium, negatively affecting its price.

 

LEGAL AND LITIGATION RISK. Uranium producers and nuclear energy companies may face legal challenges related to environmental damage, safety violations, or community health concerns. These legal issues could result in significant financial penalties, operational shutdowns, or reputational harm, impacting the value of the Fund’s holdings.

 

RISKS OF INVESTING IN EMERGING MARKETS. Some uranium producers operate in emerging markets with less developed legal, regulatory, and financial systems. Investments in these regions may carry additional risks, such as political instability, lack of transparency, and higher susceptibility to economic downturns.

Roundhill Uranium ETF | EXPOSURE CONCENTRATION RISK  
Prospectus [Line Items]  
Risk [Text Block]

EXPOSURE CONCENTRATION RISK. It is currently expected that the Fund will derive a significant amount of its economic exposure to uranium as a result of swap agreements that reference the Sprott Uranium Trust and Yellow Cake. As a result, the Fund’s performance will be highly dependent on the performance of the Sprott Uranium Trust and Yellow Cake. If, for whatever reason, shares of the Sprott Uranium Trust or Yellow Cake were to be delisted or lose their entire value, Fund Shares would also be expected to suffer a catastrophic loss of value. To the extent that the returns of the Sprott Uranium Trust or Yellow Cake do not match those experienced by the uranium market, the Fund’s returns will correspondingly fail to match such returns. The Fund’s strategy makes the Fund extremely susceptible to issuer-specific events relating to the Sprott Uranium Trust and Yellow Cake that may not necessarily affect the uranium market more broadly. This inherently makes an investment in the Fund riskier than an investment in a fund that provides more diversified exposure. Neither the Fund, Adviser nor Sub-Adviser have conducted due diligence upon the Sprott Uranium Trust or Yellow Cake and make no representations or warranties whatsoever regarding the Sprott Uranium Trust’s or Yellow Cake’s ability to acquire, dispose of or maintain proper custody of uranium. In the event that there is an issue regarding the Sprott Uranium Trust’s or Yellow Cake’s ability to acquire, dispose of or maintain proper custody of uranium, the Fund’s returns will be negatively impacted to a significant degree.

Roundhill Uranium ETF | SPROTT URANIUM TRUST RISK  
Prospectus [Line Items]  
Risk [Text Block]

SPROTT URANIUM TRUST RISK. It is currently expected that the Fund will derive a significant amount of its economic exposure to uranium as a result of swap agreements that reference the Sprott Uranium Trust. Accordingly, the Fund is especially subject to certain risks pertaining to the Sprott Uranium Trust, set forth below. In addition to these risks, the Sprott Uranium Trust is also subject to the following risks to which the Fund is also subject, which are described within the section entitled “Principal Risks”: Uranium Risk, Active Market Risk, Asset Class Risk, Concentration Risk, Cybersecurity Risk, Operational Risk and Structural ETF Risk.

 

URANIUM MARKET LIQUIDITY RISK. The uranium market is characterized by relatively low liquidity compared to other commodities. Unlike metals such as copper or gold, uranium is not traded on major commodity exchanges like the London Metal Exchange. Instead, transactions typically occur through direct negotiations between buyers and sellers, often under long-term contracts. The spot market for uranium, where transactions are made for immediate delivery, is limited in size and activity. This limited spot market activity can lead to price volatility, as even small changes in supply or demand can significantly impact prices. Accordingly, when the Sprott Uranium Trust has purchased uranium in the past, it has caused significant movements in the price of uranium.

 

URANIUM CUSTODY RISK. The Sprott Uranium Trust is tasked with the custody of its large uranium holdings. Given uranium’s potential dual-use in nuclear weapons, it is a target for theft or sabotage. Ensuring physical security at storage facilities is critical and costly. There can be no guarantee that such security measures will be effective. Uranium emits low levels of radiation, which pose safety risks. Improper handling or inadequate storage facilities could lead to health hazards for personnel and environmental contamination. Transporting uranium involves significant risk due to its hazardous nature. Accidents during transit could lead to environmental damage, regulatory fines and reputational harm. Any accident or mishandling that leads to environmental contamination could result in costly clean-up operations and long-term liabilities. The presence of uranium storage facilities may face resistance from local communities due to safety and environmental concerns, potentially disrupting operations. Additionally, moving uranium across borders or within regions often requires specialized carriers and compliance with complex international regulations. Uranium is classified as a controlled substance due to its potential use in nuclear energy and weapons. Its storage, transport, and handling are subject to stringent regulatory oversight. Failure to comply with local, national, or international regulations can result in severe legal and financial penalties. Entities involved in the custody of uranium must maintain proper licenses. Any lapse in licensing or changes in regulatory requirements could disrupt operations. Uranium requires secure, climate-controlled storage facilities to prevent degradation and contamination. Maintaining these facilities involves significant costs and operational complexities.

 

PREMIUM AND DISCOUNT RISK. The Sprott Uranium Trust is structured as a closed-end fund. Shares of closed-end funds trade on exchanges at market prices rather than net asset value and cannot be redeemed on demand. Accordingly, closed-end funds shares may trade at a price greater than net asset value (premium) or less than net asset value (discount).

 

NON-U.S. REGULATION RISK. The Sprott Uranium Trust is registered with the Ontario Securities Commission (OSC) and not the SEC. Canadian investment companies are generally subject to less stringent regulations than U.S. investment companies. While the Sprott Uranium Trust is subject to regulations set by the OSC, such rules are less burdensome than U.S. requirements, including much less prescriptive disclosure requirements. Additionally, Canada does not have an equivalent to the 1940 Act, resulting in fewer operational constraints on Canadian investment companies.

Roundhill Uranium ETF | YELLOW CAKE PLC RISK  
Prospectus [Line Items]  
Risk [Text Block]

YELLOW CAKE PLC RISK. The Fund may derive a material amount of its economic exposure to physical uranium as a result investments in securities of Yellow Cake and swap agreements that reference Yellow Cake. Accordingly, the Fund is especially subject to certain risks pertaining to Yellow Cake, set forth below. In addition the risks listed below, Yellow Cake is also subject to “Uranium Risk,” “Uranium Market Liquidity Risk” and “Uranium Custody Risk” set forth above.

 

KEY SUPPLIERS RISK. Yellow Cake’s business model is highly dependent upon its long-term agreements with a relatively small number of uranium suppliers. In particular, it has an exclusive agreement with Kazatomprom that provides Yellow Cake with access to uranium at competitive prices. In the event that, Kazatomprom or any of Yellow Cake’s other suppliers, for whatever reason, were unable or unwilling to fulfill their obligations to Yellow Cake, its business model may be significantly impacted.

 

NON-U.S. REGULATION RISK. Yellow Cake is incorporated in Jersey, Channel Islands, and is regulated by the Jersey Financial Services Commission. While Yellow Cake is subject to Jersey’s laws on corporate governance, anti-money laundering and counter-terrorism financing, such regulations are known to be less onerous than U.S. federal securities laws, resulting in fewer reporting and compliance burdens.

 

DELISTING RISK. Yellow Cake’s shares are listed on the London Stock Exchange, subjecting Yellow Cake the UK Financial Conduct Authority’s rules and regulations. To the extent that Yellow Cake were to be found out of compliance with such rules and regulations, its shares could be delisted, which would significantly negatively impact the company and its shareholders.

Roundhill Uranium ETF | GEOGRAPHIC EXPOSURE RISK  
Prospectus [Line Items]  
Risk [Text Block]

GEOGRAPHIC EXPOSURE RISK. Uranium ore production is significantly concentrated in a small number of countries, namely Kazakhstan, Canada and Australia. Accordingly, the Fund’s significant exposure to uranium will subject it to the economic, political, regulatory, or other events or conditions affecting these countries and cause the Fund to be more volatile than a more geographically diversified fund. Set forth below are a description of individual risks relating to each such country.

 

KAZAKHSTAN RISK. While Kazakhstan has a history of political stability under a centralized government in Central Asia, it remains subject to geopolitical tensions in the region. Its geographic proximity to Russia and China exposes it to risks related to diplomatic conflicts, trade disputes and regional instability. Sudden changes in government policies, leadership transitions or political unrest, such as protests or civil disturbances, could negatively impact the value of the Fund’s investments. Kazakhstan’s geopolitical ties with Russia and other neighboring countries may subject it to indirect exposure to international sanctions or trade restrictions. Companies operating in or trading with Kazakhstan (such as those producing or transporting uranium) could face restrictions that limit their ability to conduct business, access financing, or engage in international trade. Kazakhstan’s economy is heavily reliant on commodity exports, making it vulnerable to fluctuations in global commodity prices. A decline in demand or prices for these commodities could weaken the country’s economy and negatively impact businesses. Additionally, the Kazakhstani tenge (KZT) has experienced significant volatility in recent years. Currency depreciation or exchange rate instability can erode the value of investments and increase operational costs for companies operating in Kazakhstan. While Kazakhstan has made significant strides in infrastructure development, certain areas, particularly in remote regions, still face challenges. Poor infrastructure can hinder business operations, increase costs, and delay projects. Additionally, operational risks such as power outages, transportation bottlenecks and supply chain disruptions may affect companies operating in the country. The resource-intensive nature of Kazakhstan’s economy raises concerns about environmental degradation and social challenges. Regulatory scrutiny over environmental compliance is increasing, and companies may face higher costs related to environmental protection. Social risks, including labor disputes or community opposition to projects, can also impact operations and profitability. Kazakhstan is exposed to natural disasters, such as earthquakes, floods and extreme weather conditions, which can disrupt economic activity and damage infrastructure. Additionally, the country's reliance on resource extraction increases vulnerability to climate-related regulatory changes, such as carbon pricing or emission reduction mandates, which could raise negatively impact companies operating in the country.

 

CANADA RISK. Canada’s uranium industry is subject to federal and provincial regulations. Changes in government policies, environmental regulations or mining laws could adversely impact the operations and profitability of uranium companies, which could negatively affect the value of the Fund. Canadian uranium production is heavily reliant on a few key mines, such as McArthur River and Cigar Lake. Operational disruptions, whether due to technical issues, labor disputes, or environmental incidents, could materially affect the supply of uranium, impacting the Fund’s returns. Changes to the U.S. economy may significantly affect the Canadian economy because the U.S. is Canada’s largest trading partner and foreign investor. Additionally, the profitability of Canadian companies may be heavily influenced by fluctuations in the Canadian dollar relative to other global currencies, especially the U.S. dollar. These and other factors could have a negative impact on companies operating in Canada.

 

AUSTRALIA RISK. The Australian uranium industry is subject to stringent environmental and safety regulations, with mining operations requiring both federal and state approvals. While there are several projects with environmental approvals, their development is contingent on international uranium market conditions as Australia does not utilize nuclear power domestically, as nuclear energy generation is currently prohibited. The uranium industry in Australia relies on a limited number of key mines. Any operational disruptions, such as technical failures, labor disputes or environmental incidents, could reduce uranium production and negatively affect the Fund’s performance. Australia’s uranium production is primarily concentrated in South Australia. South Australia’s remote locations can pose logistical and infrastructure challenges. Companies operating in these areas may face higher transportation and operational costs, as well as risks related to supply chain disruptions. Additionally, the profitability of Australian companies may be heavily influenced by fluctuations in the Australia dollar relative to other global currencies, especially the U.S. dollar. These and other factors could have a negative impact on companies operating in Australia.

Roundhill Uranium ETF | INVESTMENT STRATEGY RISK  
Prospectus [Line Items]  
Risk [Text Block]

INVESTMENT STRATEGY RISK. The Fund seeks to provide investors with exposure to changes in the price of uranium. To the extent that the Fund achieves exposure through instruments other than Spot Uranium Derivatives, it may not provide precise exposure to movements in the price of uranium.

Roundhill Uranium ETF | SUBSIDIARY INVESTMENT RISK  
Prospectus [Line Items]  
Risk [Text Block]

SUBSIDIARY INVESTMENT RISK. Changes in the laws of the United States and/or the Cayman Islands, under which the Fund and the Subsidiary are organized, respectively, could result in the inability of the Fund to operate as intended and could negatively affect the Fund and its shareholders. The Subsidiary is not registered under the 1940 Act and is not subject to all the investor protections of the 1940 Act. However, as the Subsidiary is wholly-owned by the Fund, and the investors of the Fund will have the investor protections of the 1940 Act, the Fund as a whole—including the Subsidiary—will provide investors with 1940 Act protections.

Roundhill Uranium ETF | SWAP COUNTERPARTY CONCENTRATION RISK  
Prospectus [Line Items]  
Risk [Text Block]

SWAP COUNTERPARTY CONCENTRATION RISK. The Fund expects to engage in swap transactions with a very limited number of swap counterparties. This concentration of counterparties increases the risk of significant losses if one or more counterparties fail to perform their obligations under its swap agreement with the Fund. If a counterparty defaults, becomes insolvent, or otherwise unable to meet its financial obligations, the Fund could experience delays in recovering assets, incur additional costs, or suffer a loss of value in its portfolio. The Fund’s reliance on a small number of counterparties may also limit its ability to diversify exposure or replace a counterparty if necessary, potentially impacting the Fund’s ability to achieve its investment objectives. Moreover, counterparties are subject to various regulatory and operational risks, which may further affect their ability to fulfill contractual obligations.

NON-DIVERSIFICATION RISK. As a “non-diversified” fund, the Fund may hold a smaller number of portfolio securities than many other funds. To the extent the Fund invests in a relatively small number of issuers, a decline in the market value of a particular security held by the Fund may affect its value more than if it invested in a larger number of issuers. The value of the Fund Shares may be more volatile than the values of shares of more diversified funds.

Roundhill AAPL WeeklyPay™ ETF | MARKET RISK  
Prospectus [Line Items]  
Risk [Text Block]

MARKET RISK. Market risk is the risk that a particular investment, or Fund Shares in general, may fall in value. Securities are subject to market fluctuations caused by real or perceived adverse economic, political, and regulatory factors or market developments, changes in interest rates, disruptions to trade, impositions of tariffs and perceived trends in securities prices. Fund Shares could decline in value or underperform other investments. In addition, local, regional or global events such as war, acts of terrorism, market manipulation, government defaults, government shutdowns, regulatory actions, political changes, diplomatic developments, the imposition of sanctions and other similar measures, spread of infectious diseases or other public health issues, recessions, natural disasters, or other events could have a significant negative impact on the Fund and its investments. Any of such circumstances could have a materially negative impact on the value of Fund Shares, the liquidity of an investment, and may result in increased market volatility. During any such events, Fund Shares may trade at increased premiums or discounts to their net asset value, the bid/ask spread on Fund Shares may widen and the returns on investment may fluctuate.

Roundhill AAPL WeeklyPay™ ETF | LIQUIDITY RISK  
Prospectus [Line Items]  
Risk [Text Block]

LIQUIDITY RISK. The market for swap agreements that reference AAPL shares may be subject to periods of illiquidity. During such times it may be difficult or impossible to buy or sell a position at the desired price. Market disruptions or volatility can also make it difficult to find a counterparty willing to transact at a reasonable price and sufficient size. Illiquid markets may cause losses, which could be significant. The large size of the positions which the Fund may acquire increases the risk of illiquidity, may make its positions more difficult to liquidate, and may increase the losses incurred while trying to do so. Such large positions also may impact the price of swap agreements on AAPL shares.

Roundhill AAPL WeeklyPay™ ETF | ACTIVE MANAGEMENT RISK  
Prospectus [Line Items]  
Risk [Text Block]

ACTIVE MANAGEMENT RISK. The Fund is actively-managed and its performance reflects investment decisions that the Adviser and/or Sub-Adviser makes for the Fund. Such judgments about the Fund’s investments may prove to be incorrect. If the investments selected and the strategies employed by the Fund fail to produce the intended results, the Fund could underperform as compared to other funds with similar investment objectives and/or strategies, or could have negative returns.

Roundhill AAPL WeeklyPay™ ETF | ACTIVE MARKET RISK  
Prospectus [Line Items]  
Risk [Text Block]

ACTIVE MARKET RISK. Although Fund Shares are listed for trading on the Exchange, there can be no assurance that an active trading market for Fund Shares will develop or be maintained. Fund Shares trade on the Exchange at market prices that may be below, at or above the Fund’s net asset value. Securities, including Fund Shares, are subject to market fluctuations and liquidity constraints that may be caused by such factors as economic, political, or regulatory developments, changes in interest rates, and/or perceived trends in securities prices. Fund Shares could decline in value or underperform other investments.

Roundhill AAPL WeeklyPay™ ETF | ASSET CLASS RISK

Risk [Text Block]

CONCENTRATION RISK. The Fund is susceptible to an increased risk of loss, including losses due to adverse events that affect the Fund’s investments more than the market as a whole, to the extent that the Fund’s investments are concentrated in investments that provide exposure to AAPL and the industry to which it is assigned.

Roundhill AAPL WeeklyPay™ ETF | COUNTERPARTY RISK  
Prospectus [Line Items]  
Risk [Text Block]

COUNTERPARTY RISK. Fund transactions involving a counterparty are subject to the risk that the counterparty will not fulfill its obligation to the Fund. Counterparty risk may arise because of the counterparty’s financial condition (i.e., financial difficulties, bankruptcy, or insolvency), market activities and developments, or other reasons, whether foreseen or not. A counterparty’s inability to fulfill its obligation may result in significant financial loss to the Fund. The Fund may be unable to recover its investment from the counterparty or may obtain a limited recovery, and/or recovery may be delayed.

Prospectus [Line Items]  
Risk [Text Block]

CREDIT RISK. An issuer or other obligated party of a debt security may be unable or unwilling to make dividend, interest and/or principal payments when due. In addition, the value of a debt security may decline because of concerns about the issuer’s ability or unwillingness to make such payments.

Roundhill AAPL WeeklyPay™ ETF | CYBERSECURITY RISK  
Prospectus [Line Items]  
Risk [Text Block]

CYBERSECURITY RISK. Failures or breaches of the electronic systems of the Fund, the Fund’s adviser, sub-adviser, distributor and other service providers, market makers, Authorized Participants or the issuers of securities in which the Fund invests have the ability to cause disruptions, negatively impact the Fund’s business operations and/or potentially result in financial losses to the Fund and its shareholders. While the Fund has established business continuity plans and risk management systems seeking to address system breaches or failures, there are inherent limitations in such plans and systems. Furthermore, the Fund cannot control the cybersecurity plans and systems of the Fund’s other service providers, market makers, Authorized Participants or issuers of securities in which the Fund invests.

Roundhill AAPL WeeklyPay™ ETF | DEBT SECURITIES RISK  
Prospectus [Line Items]  
Risk [Text Block]

DEBT SECURITIES RISK. Investments in debt securities subject the holder to the credit risk of the issuer. Credit risk refers to the possibility that the issuer or other obligor of a security will not be able or willing to make payments of interest and principal when due. Generally, the value of debt securities will change inversely with changes in interest rates. To the extent that interest rates rise, certain underlying obligations may be paid off substantially slower than originally anticipated and the value of those securities may fall sharply. During periods of falling interest rates, the income received by the Fund may decline. If the principal on a debt security is prepaid before expected, the prepayments of principal may have to be reinvested in obligations paying interest at lower rates. Debt securities generally do not trade on a securities exchange making them generally less liquid and more difficult to value than common stock.

Roundhill AAPL WeeklyPay™ ETF | DERIVATIVES RISK  
Prospectus [Line Items]  
Risk [Text Block]

DERIVATIVES RISK. The use of derivative instruments involves risks different from, or possibly greater than, the risks associated with investing directly in securities and other traditional investments. These risks include: (i) the risk that the counterparty to a derivative transaction may not fulfill its contractual obligations; (ii) risk of mispricing or improper valuation; and (iii) the risk that changes in the value of the derivative may not correlate perfectly with the underlying asset. Derivative prices are highly volatile and may fluctuate substantially during a short period of time. Such prices are influenced by numerous factors that affect the markets, including, but not limited to: changing supply and demand relationships; government programs and policies; national and international political and economic events, changes in interest rates, inflation and deflation and changes in supply and demand relationships. Trading derivative instruments involves risks different from, or possibly greater than, the risks associated with investing directly in securities. Derivative contracts ordinarily have leverage inherent in their terms. The use of leverage may cause the Fund to liquidate portfolio positions when it would not be advantageous to do so in order to satisfy its obligations or to meet regulatory or contractual requirements for derivatives. The use of derivatives can magnify potential for gain or loss and, therefore, amplify the effects of market volatility on the Fund Share price.

Roundhill AAPL WeeklyPay™ ETF | DISTRIBUTION TAX RISK  
Prospectus [Line Items]  
Risk [Text Block]

DISTRIBUTION TAX RISK. The Fund currently expects to make distributions on a weekly basis. Such frequent distributions may expose investors to increased tax liabilities. However, these distributions may exceed the Fund’s income and gains for the Fund’s taxable year. Distributions in excess of the Fund’s current and accumulated earnings and profits will be treated as a return of capital. A return of capital distribution generally will not be taxable but will reduce the shareholder’s cost basis and will result in a higher capital gain or lower capital loss when those Fund Shares on which the distribution was received are sold. Once the Fund shareholder’s cost basis is reduced to zero, further distributions will be treated as capital gain if the Fund shareholder holds Fund Shares as capital assets. Additionally, any capital returned through distributions will be distributed after payment of Fund fees and expenses. Because a portion of the Fund’s distributions may consist of return of capital, the Fund may not be an appropriate investment for investors who do not want their principal investment in the Fund to decrease over time or who do not wish to receive return of capital in a given period. In the event that a shareholder purchases Fund Shares shortly before a distribution by the Fund, the entire distribution may be taxable to the shareholder even though a portion of the distribution effectively represents a return of the purchase price.

Roundhill AAPL WeeklyPay™ ETF | ETF RISK  
Prospectus [Line Items]  
Risk [Text Block]

ETF RISK. The Fund may invest in ETFs. The value of an ETF held by the Fund will fluctuate over time based on fluctuations in the values of the assets held by the ETF, which may be affected by changes in general economic conditions, expectations for future growth and profits, interest rates and the supply and demand for those assets. When the Fund invests in an ETF, it will bear a proportionate share of the ETF’s expenses. Brokerage, tax and other expenses may negatively impact the performance of the ETF and, in turn, the value of the Fund Shares. An ETF that tracks an index may not exactly match the performance of the index due to cash drag, differences between the portfolio of the ETF and the components of the index, expenses and other factors.

Roundhill AAPL WeeklyPay™ ETF | INFLATION RISK  
Prospectus [Line Items]  
Risk [Text Block]

INFLATION RISK. Inflation risk is the risk that the value of assets or income from investments will be less in the future as inflation decreases the value of money. As inflation increases, the present value of the Fund’s assets and distributions may decline. This risk is more prevalent with respect to fixed income securities held by the Fund.

Roundhill AAPL WeeklyPay™ ETF | Interest Rate Risk [Member]  
Prospectus [Line Items]  
Risk [Text Block]

INTEREST RATE RISK. Interest rate risk is the risk that the value of the debt securities in the Fund’s portfolio will decline because of rising market interest rates. Interest rate risk is generally lower for shorter term debt securities and higher for longer-term debt securities. Duration is a reasonably accurate measure of a debt security’s price sensitivity to changes in interest rates and a common measure of interest rate risk. Duration measures a debt security’s expected life on a present value basis, taking into account the debt security’s yield, interest payments and final maturity. In general, duration represents the expected percentage change in the value of a security for an immediate 1% change in interest rates. For example, the price of a debt security with a three-year duration would be expected to drop by approximately 3% in response to a 1% increase in interest rates. Therefore, prices of debt securities with shorter durations tend to be less sensitive to interest rate changes than debt securities with longer durations. As the value of a debt security changes over time, so will its duration.

Roundhill AAPL WeeklyPay™ ETF | LEGISLATION AND LITIGATION RISK  
Prospectus [Line Items]  
Risk [Text Block]

LEGISLATION AND LITIGATION RISK. Legislation or litigation that affects the value of assets or securities held by the Fund may reduce the value of the Fund. From time to time, various legislative initiatives are proposed that may have a negative impact on certain assets or securities in which the Fund invests. In addition, litigation regarding any of the assets or securities owned by the Fund may negatively impact the value of the Shares. Such legislation or litigation may cause the Fund to lose value or may result in higher portfolio turnover if the Adviser determines to sell such a holding.

Roundhill AAPL WeeklyPay™ ETF | LEVERAGE RISK  
Prospectus [Line Items]  
Risk [Text Block]

LEVERAGE RISK. The Fund obtains investment exposure in excess of its net assets by utilizing leverage and may lose more money in market conditions that are adverse to its investment objectives than a fund that does not utilize leverage. An investment in the Fund is exposed to the risk that a decline in the weekly performance of shares of AAPL will be magnified. This means that an investment in the Fund will be reduced by an amount equal to 1.2% for every 1% weekly decline in the market value of the AAPL shares, not including the costs of financing leverage and other operating expenses, which would further reduce its value. The Fund could theoretically lose an amount greater than its net assets in the event the market value of AAPL shares decline more than 83.33% over a calendar week. Leverage will also have the effect of magnifying any differences in the Fund’s correlation with AAPL shares.

Roundhill AAPL WeeklyPay™ ETF | MONEY MARKET INSTRUMENTS RISK  
Prospectus [Line Items]  
Risk [Text Block]

MONEY MARKET INSTRUMENTS RISK. The value of money market instruments may be affected by changing interest rates and by changes in the credit ratings of the investments. If a significant amount of the Fund’s assets are invested in money market instruments, it will be more difficult for the Fund to achieve its investment objectives. An investment in a money market fund is not insured or guaranteed by the FDIC or any other government agency. It is possible to lose money by investing in a money market fund.

Roundhill AAPL WeeklyPay™ ETF | OPERATIONAL RISK  
Prospectus [Line Items]  
Risk [Text Block]

OPERATIONAL RISK. The Fund is subject to risks arising from various operational factors, including, but not limited to, human error, processing and communication errors, errors of the Fund’s service providers, counterparties or other third-parties, failed or inadequate processes and technology or systems failures. The Fund relies on third-parties for a range of services, including custody. Any delay or failure relating to engaging or maintaining such service providers may affect the Fund’s ability to meet its investment objectives. Although the Fund and the Adviser seek to reduce these operational risks through controls and procedures, there is no way to completely protect against such risks.

Roundhill AAPL WeeklyPay™ ETF | SPECIAL TAX RISK  
Prospectus [Line Items]  
Risk [Text Block]

SPECIAL TAX RISK. The Fund intends to qualify annually and to elect to be treated as a regulated investment company under the Internal Revenue Code of 1986, as amended (the “Code”). To qualify for the favorable U.S. federal income tax treatment generally accorded to regulated investment companies, the Fund must, among other things, (i) derive in each taxable year at least 90% of its gross income from dividends, interest, payments with respect to securities loans and gains from the sale or other disposition of stock, securities or foreign currencies or other income derived with respect to its business of investing in such stock, securities or currencies, or net income derived from interests in certain publicly traded partnerships; (ii) diversify its holdings so that, at the end of each quarter of the taxable year, (a) at least 50% of the market value of the Fund’s assets is represented by cash and cash items (including receivables), U.S. government securities, the securities of other regulated investment companies and other securities, with such other securities of any one issuer generally limited for the purposes of this calculation to an amount not greater than 5% of the value of the Fund’s total assets and not greater than 10% of the outstanding voting securities of such issuer, and (b) not more than 25% of the value of its total assets is invested in the securities (other than U.S. government securities or the securities of other regulated investment companies) of any one issuer, or two or more issuers which the Fund controls which are engaged in the same, similar or related trades or businesses, or the securities of one or more of certain publicly traded partnerships; and (iii) distribute at least 90% of its investment company taxable income (which includes, among other items, dividends, interest and net short-term capital gains in excess of net long-term capital losses) and at least 90% of its net tax-exempt interest income each taxable year. There are certain exceptions for failure to qualify if the failure is for reasonable cause or is de minimis, and certain corrective action is taken and certain tax payments are made by the Fund.

 

The authority with regard to swaps entered into by regulated investment companies is unclear both as to the qualification under the income test and the identification of the issuer under the diversification test. The Fund intends to take the position that because the swaps held by the Fund reference securities that the income on the swaps are “other income” from the Fund’s business of investing in stocks and securities. In addition, the Fund intends to manage its investments in the swaps so that neither the exposure to issuer of the referenced security nor the exposure to any one counterparty of the swaps will exceed 25% of the gross value of the Fund’s portfolio at the end of any quarter.

 

If the Fund were to fail to meet the qualifying income test or asset diversification test and fail to qualify as a RIC, it would be taxed in the same manner as an ordinary corporation, and distributions to its shareholders would not be deductible by the Fund in computing its taxable income, which would adversely affect the Fund’s performance.

Roundhill AAPL WeeklyPay™ ETF | STRUCTURAL ETF RISKS  
Prospectus [Line Items]  
Risk [Text Block]

STRUCTURAL ETF RISKS. The Fund is an ETF. Accordingly, it is subject to certain risks associated with its unique structure.

 

Market Participants Risk. Only an Authorized Participant may engage in creation or redemption transactions directly with the Fund, and none of those Authorized Participants is obligated to engage in creation and/or redemption transactions. The Fund has a limited number of institutions that may act as Authorized Participants on an agency basis (i.e., on behalf of other market participants). To the extent that Authorized Participants exit the business or are unable to proceed with creation or redemption orders with respect to the Fund and no other Authorized Participant is able to step forward to create or redeem, Fund Shares may be more likely to trade at a premium or discount to NAV and possibly face trading halts or delisting. The Fund may also rely on a small number of third-party market makers to provide a market for the purchase and sale of Fund Shares but such market makers are under no obligation to do so. Decisions by Authorized Participants or market makers to reduce their role or step away from these activities in times of market stress could inhibit the effectiveness of the arbitrage process in maintaining the relationship between the underlying values of the Fund’s portfolio securities and the Fund’s market price. Any trading halt or other problem relating to the trading activity of these market makers or any issues disrupting the Authorized Participants’ ability to proceed with creation and/or redemption orders could result in a dramatic change in the spread between the Fund’s net asset value and the price at which Fund Shares are trading on the Exchange, which could result in a decrease in value of Fund Shares. This reduced effectiveness could result in Fund Shares trading at a premium or discount to net asset value and also in greater than normal intraday bid-ask spreads Fund Shares.

 

Cash Transactions Risk. The Fund currently expects to effect a significant portion of its creations and redemptions for cash, rather than in-kind securities. Paying redemption proceeds in cash rather than through in-kind delivery of portfolio securities may require the Fund to dispose of or sell portfolio securities or other assets at an inopportune time to obtain the cash needed to meet redemption orders. This may cause the Fund to sell a security and recognize a capital gain or loss that might not have been incurred if it had made a redemption in-kind. As a result, the Fund may pay out higher or lower annual capital gains distributions than ETFs that redeem in-kind. The use of cash creations and redemptions may also cause the Fund’s Shares to trade in the market at greater bid-ask spreads or greater premiums or discounts to the Fund’s net asset value (“NAV”). Furthermore, the Fund may not be able to execute cash transactions for creation and redemption purposes at the same price used to determine the Fund’s NAV. To the extent that the maximum additional charge for creation or redemption transactions is insufficient to cover the execution shortfall, the Fund’s performance could be negatively impacted.

 

Costs of Buying and Selling Fund Shares. Due to the costs of buying or selling Fund Shares, including brokerage commissions imposed by brokers and bid/ask spreads, frequent trading of Fund Shares may significantly reduce investment results and an investment in Fund Shares may not be advisable for investors who anticipate regularly making small investments.

 

Premium/Discount Risk. As with all ETFs, Fund Shares may be bought and sold in the secondary market at market prices. The trading prices of Fund Shares in the secondary market may differ from the Fund’s daily NAV per Fund Share and there may be times when the market price of the Fund Shares is more than the NAV per Fund Share (premium) or less than the NAV per Fund Share (discount). If a shareholder purchases Fund Shares at a time when the market price is at a premium to the NAV or sells Fund Shares at a time when the market price is at a discount to the NAV, the shareholder may pay more for, or receive less than, the underlying value of the Fund Shares, respectively. This risk is heightened in times of market volatility or periods of steep market declines.

 

Trading Risks. Although Fund Shares are listed for trading on the Exchange and may be traded on U.S. exchanges other than the Exchange, there can be no assurance that Fund Shares will trade with any volume, or at all, on any stock exchange. In stressed market conditions, the liquidity of Fund Shares may begin to mirror the liquidity of the Fund’s underlying portfolio holdings, which can be significantly less liquid than Fund Shares. Trading in Fund Shares on the Exchange may be halted due to market conditions or for reasons that, in the view of the Exchange, make trading in Fund Shares inadvisable. In addition, trading in Fund Shares on the Exchange is subject to trading halts caused by extraordinary market volatility pursuant to the Exchange’s “circuit breaker” rules. There can be no assurance that the requirements of the Exchange necessary to maintain the listing of the Fund will continue to be met or will remain unchanged.

Roundhill AAPL WeeklyPay™ ETF | U.S. GOVERNMENT SECURITIES RISK  
Prospectus [Line Items]  
Risk [Text Block]

U.S. GOVERNMENT SECURITIES RISK. U.S. government securities are subject to interest rate risk but generally do not involve the credit risks associated with investments in other types of debt securities. As a result, the yields available from U.S. government securities are generally lower than the yields available from other debt securities. U.S. government securities are guaranteed only as to the timely payment of interest and the payment of principal when held to maturity.

Roundhill AAPL WeeklyPay™ ETF | VALUATION RISK  
Prospectus [Line Items]  
Risk [Text Block]

VALUATION RISK. The Fund may hold securities or other assets that may be valued on the basis of factors other than market quotations. This may occur because the asset or security does not trade on a centralized exchange, or in times of market turmoil or reduced liquidity. There are multiple methods that can be used to value a portfolio holding when market quotations are not readily available. The value established for any portfolio holding at a point in time might differ from what would be produced using a different methodology or if it had been priced using market quotations. Portfolio holdings that are valued using techniques other than market quotations, including “fair valued” assets or securities, may be subject to greater fluctuation in their valuations from one day to the next than if market quotations were used. In addition, there is no assurance that the Fund could sell or close out a portfolio position for the value established for it at any time, and it is possible that the Fund would incur a loss because a portfolio position is sold or closed out at a discount to the valuation established by the Fund at that time. The Fund’s ability to value investments may be impacted by technological issues or errors by pricing services or other third-party service providers.

Roundhill AAPL WeeklyPay™ ETF | EQUITY SECURITIES RISK  
Prospectus [Line Items]  
Risk [Text Block]

EQUITY SECURITIES RISK. Equity securities are subject to changes in value, and their values may be more volatile than those of other asset classes. Equity securities prices fluctuate for several reasons, including changes in investors’ perceptions of the financial condition of an issuer or the general condition of the relevant equity market, such as market volatility, or when political or economic events affecting an issuer occur. Common stock prices may be particularly sensitive to rising interest rates, as the cost of capital rises and borrowing costs increase. Common stocks generally subject their holders to more risks than preferred stocks and debt securities because common stockholders’ claims are subordinated to those of holders of preferred stocks and debt securities upon the bankruptcy of the issuer.

Roundhill AAPL WeeklyPay™ ETF | SWAP AGREEMENTS RISK  
Prospectus [Line Items]  
Risk [Text Block]

SWAP AGREEMENTS RISK. The Fund will utilize swap agreements to derive its exposure to shares of AAPL. Swap agreements may involve greater risks than direct investment in securities as they may be leveraged and are subject to credit risk, counterparty risk and valuation risk. A swap agreement could result in losses if the underlying reference or asset does not perform as anticipated. In addition, many swaps trade over-the-counter and may be considered illiquid. It may not be possible for the Fund to liquidate a swap position at an advantageous time or price, which may result in significant losses.

Roundhill AAPL WeeklyPay™ ETF | REGULATED INVESTMENT COMPANY TAX RISKS  
Prospectus [Line Items]  
Risk [Text Block]

REGULATED INVESTMENT COMPANY TAX RISKS. The Fund intends to qualify annually and to elect to be treated as a regulated investment company under the Internal Revenue Code of 1986, as amended (the “Code”). To qualify for the favorable U.S. federal income tax treatment generally accorded to regulated investment companies, the Fund must, among other things, (i) derive in each taxable year at least 90% of its gross income from dividends, interest, payments with respect to securities loans and gains from the sale or other disposition of stock, securities or foreign currencies or other income derived with respect to its business of investing in such stock, securities or currencies, or net income derived from interests in certain publicly traded partnerships; (ii) diversify its holdings so that, at the end of each quarter of the taxable year, (a) at least 50% of the market value of the Fund’s assets is represented by cash and cash items (including receivables), U.S. government securities, the securities of other regulated investment companies and other securities, with such other securities of any one issuer generally limited for the purposes of this calculation to an amount not greater than 5% of the value of the Fund’s total assets and not greater than 10% of the outstanding voting securities of such issuer, and (b) not more than 25% of the value of its total assets is invested in the securities (other than U.S. government securities or the securities of other regulated investment companies) of any one issuer, or two or more issuers which the Fund controls which are engaged in the same, similar or related trades or businesses, or the securities of one or more of certain publicly traded partnerships; and (iii) distribute at least 90% of its investment company taxable income (which includes, among other items, dividends, interest and net short-term capital gains in excess of net long-term capital losses) and at least 90% of its net tax-exempt interest income each taxable year. There are certain exceptions for failure to qualify if the failure is for reasonable cause or is de minimis, and certain corrective action is taken and certain tax payments are made by the Fund.

 

If the Fund were to fail to meet the qualifying income test or asset diversification test and fail to qualify as a RIC, it would be taxed in the same manner as an ordinary corporation, and distributions to its shareholders would not be deductible by the Fund in computing its taxable income, which would adversely affect the Fund’s performance.

Roundhill AAPL WeeklyPay™ ETF | LARGE SHAREHOLDER RISK  
Prospectus [Line Items]  
Risk [Text Block]

LARGE SHAREHOLDER RISK. Certain shareholders, including affiliated funds advised by the Adviser, may from time to time own a significant portion of the Fund’s shares. In addition, a third-party investor, the Adviser or an affiliate of the Adviser (“Affiliate”), an authorized participant, a market maker, or another entity may invest in the Fund and hold its investment for a limited period solely to facilitate the commencement of the Fund or to help the Fund achieve a specified size or scale. There can be no assurance that any large shareholder will not redeem its investment, that the size of the Fund will be maintained at such levels, or that the Fund will continue to meet applicable listing requirements. Redemptions by large shareholders could have a significant negative impact on the Fund. In addition, transactions by large shareholders may account for a large percentage of the trading volume on the Fund’s listing exchange and may, therefore, have a material upward or downward effect on the market price of the shares.

 

To the extent that a significant percentage of the Fund’s shares are owned or controlled by a small number of account shareholders (or a single account shareholder), including funds or accounts over which the Adviser or an Affiliate has investment discretion, the Fund is subject to the risk that those shareholders may purchase or redeem Fund shares in significant amounts rapidly or unexpectedly, including as a result of an asset allocation decision made by the Adviser or an Affiliate. This may adversely affect the Fund’s performance if the Adviser is forced to sell portfolio securities or invest cash when it would not otherwise choose to do so. Redemptions of a large number of shares may affect the liquidity of the Fund’s portfolio, increase the Fund’s transaction costs, and accelerate the realization of taxable income and/or gains. In addition, a large redemption could result in the Fund’s current expenses being allocated over a smaller asset base, leading to an increase in the Fund’s gross expense ratio. Large purchases of the Fund’s shares may also adversely affect the Fund’s performance to the extent that the Fund is delayed in investing new cash or otherwise maintains a larger cash position than it ordinarily would, particularly if the Fund accepts cash for an order for the purchase of creation units of the Fund’s shares.

Roundhill AAPL WeeklyPay™ ETF | AAPL INVESTING RISKS  
Prospectus [Line Items]  
Risk [Text Block]

AAPL INVESTING RISKS. The Fund will have significant exposure to AAPL through its investments in swap agreements that utilize AAPL as the reference asset. Accordingly, the Fund will subject to the risks of AAPL, set forth below.

 

AAPL ISSUER-SPECIFIC RISKS. Issuer-specific attributes may cause an investment held by the Fund to be more volatile than the market generally. The value of an individual security or particular type of security may be more volatile than the market as a whole and may perform differently from the value of the market as a whole. As of the date of this prospectus, in addition to the risks associated with companies in the technology sector, AAPL faces risks related to: global and economic conditions; market disrupting events, such as wars, natural disasters and public health issues; highly competitive global demand and rapidly changing technology; managing the frequent introductions and transitions of products and services; the outsourced manufacturing and logistical services provided by partners, many of which are located outside of the United States; the ability to obtain components in sufficient quantities on commercially reasonable terms for its products; potential design and manufacturing defects in its products and services; write-downs on the value of the company’s inventory and other assets; the reliance on access to third-party intellectual property and on third-party software developers; ability to obtain or create digital content that appeals to customers; the ability to retain and hire highly skilled employees, including key personnel; the performance of carriers, wholesalers, retailers and other resellers; information technology system failures and network disruptions; losses or unauthorized access to or releases of confidential information; investments in new business strategies may disrupt the current activities, changing needs and costs related to the company’s retail stores; and legal and regulatory compliance risks.

 

INDIRECT INVESTMENT RISK. Apple Inc. is not affiliated with the Trust, the Fund, the Adviser, the Sub-Adviser or any affiliates thereof and is not involved with this offering in any way, and has no obligation to consider the Fund in taking any corporate actions that might affect the value of the Fund. The Trust, the Fund, the Adviser, the Sub-Adviser or any affiliate are not responsible for the performance of AAPL and make no representation as to the performance of AAPL. Investing in the Fund is not equivalent to investing in AAPL. Fund shareholders will not have voting rights or rights to receive dividends or other distributions or any other rights with respect to AAPL.

 

INFORMATION TECHNOLOGY COMPANIES RISK. Information technology companies face intense competition, both domestically and internationally, which may have an adverse effect on profit margins. Like other technology companies, information technology companies may have limited product lines, markets, financial resources or personnel. The products of information technology companies may face obsolescence due to rapid technological developments, frequent new product introduction, unpredictable changes in growth rates and competition for the services of qualified personnel. Companies in the information technology sector are heavily dependent on patent and intellectual property rights. The loss or impairment of these rights may adversely affect the profitability of these companies. Information technology companies are facing increased government and regulatory scrutiny and may be subject to adverse government or regulatory action.

 

LARGE CAPITALIZATION COMPANIES RISK. Large capitalization companies may be less able than smaller capitalization companies to adapt to changing market conditions. Large capitalization companies may be more mature and subject to more limited growth potential compared with smaller capitalization companies. During different market cycles, the performance of large capitalization companies has trailed the overall performance of the broader securities markets.

 

UNITED STATES RISK. Certain changes in the U.S. economy, such as when the U.S. economy weakens or when its financial markets decline, may have an adverse effect on the securities to which the Fund has exposure.

NON-DIVERSIFICATION RISK. As a “non-diversified” fund, the Fund may hold a smaller number of portfolio securities than many other funds. To the extent the Fund invests in a relatively small number of issuers, a decline in the market value of a particular security held by the Fund may affect its value more than if it invested in a larger number of issuers. The value of the Fund Shares may be more volatile than the values of shares of more diversified funds.

Roundhill AMD WeeklyPay™ ETF | MARKET RISK  
Prospectus [Line Items]  
Risk [Text Block]

MARKET RISK. Market risk is the risk that a particular investment, or Fund Shares in general, may fall in value. Securities are subject to market fluctuations caused by real or perceived adverse economic, political, and regulatory factors or market developments, changes in interest rates, disruptions to trade, impositions of tariffs and perceived trends in securities prices. Fund Shares could decline in value or underperform other investments. In addition, local, regional or global events such as war, acts of terrorism, market manipulation, government defaults, government shutdowns, regulatory actions, political changes, diplomatic developments, the imposition of sanctions and other similar measures, spread of infectious diseases or other public health issues, recessions, natural disasters, or other events could have a significant negative impact on the Fund and its investments. Any of such circumstances could have a materially negative impact on the value of Fund Shares, the liquidity of an investment, and may result in increased market volatility. During any such events, Fund Shares may trade at increased premiums or discounts to their net asset value, the bid/ask spread on Fund Shares may widen and the returns on investment may fluctuate.

Roundhill AMD WeeklyPay™ ETF | LIQUIDITY RISK  
Prospectus [Line Items]  
Risk [Text Block]

LIQUIDITY RISK. The market for swap agreements that reference AMD shares may be subject to periods of illiquidity. During such times it may be difficult or impossible to buy or sell a position at the desired price. Market disruptions or volatility can also make it difficult to find a counterparty willing to transact at a reasonable price and sufficient size. Illiquid markets may cause losses, which could be significant. The large size of the positions which the Fund may acquire increases the risk of illiquidity, may make its positions more difficult to liquidate, and may increase the losses incurred while trying to do so. Such large positions also may impact the price of swap agreements on AMD shares.

Roundhill AMD WeeklyPay™ ETF | ACTIVE MANAGEMENT RISK  
Prospectus [Line Items]  
Risk [Text Block]

ACTIVE MANAGEMENT RISK. The Fund is actively-managed and its performance reflects investment decisions that the Adviser and/or Sub-Adviser makes for the Fund. Such judgments about the Fund’s investments may prove to be incorrect. If the investments selected and the strategies employed by the Fund fail to produce the intended results, the Fund could underperform as compared to other funds with similar investment objectives and/or strategies, or could have negative returns.

Roundhill AMD WeeklyPay™ ETF | ACTIVE MARKET RISK  
Prospectus [Line Items]  
Risk [Text Block]

ACTIVE MARKET RISK. Although Fund Shares are listed for trading on the Exchange, there can be no assurance that an active trading market for Fund Shares will develop or be maintained. Fund Shares trade on the Exchange at market prices that may be below, at or above the Fund’s net asset value. Securities, including Fund Shares, are subject to market fluctuations and liquidity constraints that may be caused by such factors as economic, political, or regulatory developments, changes in interest rates, and/or perceived trends in securities prices. Fund Shares could decline in value or underperform other investments.

Roundhill AMD WeeklyPay™ ETF | ASSET CLASS RISK

Risk [Text Block]

CONCENTRATION RISK. The Fund is susceptible to an increased risk of loss, including losses due to adverse events that affect the Fund’s investments more than the market as a whole, to the extent that the Fund’s investments are concentrated in investments that provide exposure to AMD and the industry to which it is assigned.

Roundhill AMD WeeklyPay™ ETF | COUNTERPARTY RISK  
Prospectus [Line Items]  
Risk [Text Block]

COUNTERPARTY RISK. Fund transactions involving a counterparty are subject to the risk that the counterparty will not fulfill its obligation to the Fund. Counterparty risk may arise because of the counterparty’s financial condition (i.e., financial difficulties, bankruptcy, or insolvency), market activities and developments, or other reasons, whether foreseen or not. A counterparty’s inability to fulfill its obligation may result in significant financial loss to the Fund. The Fund may be unable to recover its investment from the counterparty or may obtain a limited recovery, and/or recovery may be delayed.

CREDIT RISK. An issuer or other obligated party of a debt security may be unable or unwilling to make dividend, interest and/or principal payments when due. In addition, the value of a debt security may decline because of concerns about the issuer’s ability or unwillingness to make such payments.

Roundhill AMD WeeklyPay™ ETF | CYBERSECURITY RISK  
Prospectus [Line Items]  
Risk [Text Block]

CYBERSECURITY RISK. Failures or breaches of the electronic systems of the Fund, the Fund’s adviser, sub-adviser, distributor and other service providers, market makers, Authorized Participants or the issuers of securities in which the Fund invests have the ability to cause disruptions, negatively impact the Fund’s business operations and/or potentially result in financial losses to the Fund and its shareholders. While the Fund has established business continuity plans and risk management systems seeking to address system breaches or failures, there are inherent limitations in such plans and systems. Furthermore, the Fund cannot control the cybersecurity plans and systems of the Fund’s other service providers, market makers, Authorized Participants or issuers of securities in which the Fund invests.

Roundhill AMD WeeklyPay™ ETF | DEBT SECURITIES RISK  
Prospectus [Line Items]  
Risk [Text Block]

DEBT SECURITIES RISK. Investments in debt securities subject the holder to the credit risk of the issuer. Credit risk refers to the possibility that the issuer or other obligor of a security will not be able or willing to make payments of interest and principal when due. Generally, the value of debt securities will change inversely with changes in interest rates. To the extent that interest rates rise, certain underlying obligations may be paid off substantially slower than originally anticipated and the value of those securities may fall sharply. During periods of falling interest rates, the income received by the Fund may decline. If the principal on a debt security is prepaid before expected, the prepayments of principal may have to be reinvested in obligations paying interest at lower rates. Debt securities generally do not trade on a securities exchange making them generally less liquid and more difficult to value than common stock.

Roundhill AMD WeeklyPay™ ETF | DERIVATIVES RISK  
Prospectus [Line Items]  
Risk [Text Block]

DERIVATIVES RISK. The use of derivative instruments involves risks different from, or possibly greater than, the risks associated with investing directly in securities and other traditional investments. These risks include: (i) the risk that the counterparty to a derivative transaction may not fulfill its contractual obligations; (ii) risk of mispricing or improper valuation; and (iii) the risk that changes in the value of the derivative may not correlate perfectly with the underlying asset. Derivative prices are highly volatile and may fluctuate substantially during a short period of time. Such prices are influenced by numerous factors that affect the markets, including, but not limited to: changing supply and demand relationships; government programs and policies; national and international political and economic events, changes in interest rates, inflation and deflation and changes in supply and demand relationships. Trading derivative instruments involves risks different from, or possibly greater than, the risks associated with investing directly in securities. Derivative contracts ordinarily have leverage inherent in their terms. The use of leverage may cause the Fund to liquidate portfolio positions when it would not be advantageous to do so in order to satisfy its obligations or to meet regulatory or contractual requirements for derivatives. The use of derivatives can magnify potential for gain or loss and, therefore, amplify the effects of market volatility on share price.

Roundhill AMD WeeklyPay™ ETF | DISTRIBUTION TAX RISK  
Prospectus [Line Items]  
Risk [Text Block]

DISTRIBUTION TAX RISK. The Fund currently expects to make distributions on a weekly basis. Such frequent distributions may expose investors to increased tax liabilities. However, these distributions may exceed the Fund’s income and gains for the Fund’s taxable year. Distributions in excess of the Fund’s current and accumulated earnings and profits will be treated as a return of capital. A return of capital distribution generally will not be taxable but will reduce the shareholder’s cost basis and will result in a higher capital gain or lower capital loss when those Fund Shares on which the distribution was received are sold. Once a Fund shareholder’s cost basis is reduced to zero, further distributions will be treated as capital gain if the Fund shareholder holds Fund Shares as capital assets. Additionally, any capital returned through distributions will be distributed after payment of Fund fees and expenses. Because a portion of the Fund’s distributions may consist of return of capital, the Fund may not be an appropriate investment for investors who do not want their principal investment in the Fund to decrease over time or who do not wish to receive return of capital in a given period. In the event that a shareholder purchases Fund Shares shortly before a distribution by the Fund, the entire distribution may be taxable to the shareholder even though a portion of the distribution effectively represents a return of the purchase price.

Roundhill AMD WeeklyPay™ ETF | ETF RISK  
Prospectus [Line Items]  
Risk [Text Block]

ETF RISK. The Fund may invest in ETFs. The value of an ETF held by the Fund will fluctuate over time based on fluctuations in the values of the assets held by the ETF, which may be affected by changes in general economic conditions, expectations for future growth and profits, interest rates and the supply and demand for those assets. When the Fund invests in an ETF, it will bear a proportionate share of the ETF’s expenses. Brokerage, tax and other expenses may negatively impact the performance of the ETF and, in turn, the value of the Fund Shares. An ETF that tracks an index may not exactly match the performance of the index due to cash drag, differences between the portfolio of the ETF and the components of the index, expenses and other factors.

Roundhill AMD WeeklyPay™ ETF | INFLATION RISK  
Prospectus [Line Items]  
Risk [Text Block]

INFLATION RISK. Inflation risk is the risk that the value of assets or income from investments will be less in the future as inflation decreases the value of money. As inflation increases, the present value of the Fund’s assets and distributions may decline. This risk is more prevalent with respect to fixed income securities held by the Fund.

Roundhill AMD WeeklyPay™ ETF | Interest Rate Risk [Member]  
Prospectus [Line Items]  
Risk [Text Block]

INTEREST RATE RISK. Interest rate risk is the risk that the value of the debt securities in the Fund’s portfolio will decline because of rising market interest rates. Interest rate risk is generally lower for shorter term debt securities and higher for longer-term debt securities. Duration is a reasonably accurate measure of a debt security’s price sensitivity to changes in interest rates and a common measure of interest rate risk. Duration measures a debt security’s expected life on a present value basis, taking into account the debt security’s yield, interest payments and final maturity. In general, duration represents the expected percentage change in the value of a security for an immediate 1% change in interest rates. For example, the price of a debt security with a three-year duration would be expected to drop by approximately 3% in response to a 1% increase in interest rates. Therefore, prices of debt securities with shorter durations tend to be less sensitive to interest rate changes than debt securities with longer durations. As the value of a debt security changes over time, so will its duration.

Roundhill AMD WeeklyPay™ ETF | LEGISLATION AND LITIGATION RISK  
Prospectus [Line Items]  
Risk [Text Block]

LEGISLATION AND LITIGATION RISK. Legislation or litigation that affects the value of assets or securities held by the Fund may reduce the value of the Fund. From time to time, various legislative initiatives are proposed that may have a negative impact on certain assets or securities in which the Fund invests. In addition, litigation regarding any of the assets or securities owned by the Fund may negatively impact the value of the Shares. Such legislation or litigation may cause the Fund to lose value or may result in higher portfolio turnover if the Adviser determines to sell such a holding.

Roundhill AMD WeeklyPay™ ETF | LEVERAGE RISK  
Prospectus [Line Items]  
Risk [Text Block]

LEVERAGE RISK. The Fund obtains investment exposure in excess of its net assets by utilizing leverage and may lose more money in market conditions that are adverse to its investment objectives than a fund that does not utilize leverage. An investment in the Fund is exposed to the risk that a decline in the weekly performance of shares of AMD will be magnified. This means that an investment in the Fund will be reduced by an amount equal to 1.2% for every 1% weekly decline in the market value of the AMD shares, not including the costs of financing leverage and other operating expenses, which would further reduce its value. The Fund could theoretically lose an amount greater than its net assets in the event the market value of AMD shares decline more than 83.33% over a calendar week. Leverage will also have the effect of magnifying any differences in the Fund’s correlation with AMD shares.

Roundhill AMD WeeklyPay™ ETF | MONEY MARKET INSTRUMENTS RISK  
Prospectus [Line Items]  
Risk [Text Block]

MONEY MARKET INSTRUMENTS RISK. The value of money market instruments may be affected by changing interest rates and by changes in the credit ratings of the investments. If a significant amount of the Fund’s assets are invested in money market instruments, it will be more difficult for the Fund to achieve its investment objectives. An investment in a money market fund is not insured or guaranteed by the FDIC or any other government agency. It is possible to lose money by investing in a money market fund.

Roundhill AMD WeeklyPay™ ETF | OPERATIONAL RISK  
Prospectus [Line Items]  
Risk [Text Block]

OPERATIONAL RISK. The Fund is subject to risks arising from various operational factors, including, but not limited to, human error, processing and communication errors, errors of the Fund’s service providers, counterparties or other third-parties, failed or inadequate processes and technology or systems failures. The Fund relies on third-parties for a range of services, including custody. Any delay or failure relating to engaging or maintaining such service providers may affect the Fund’s ability to meet its investment objectives. Although the Fund and the Adviser seek to reduce these operational risks through controls and procedures, there is no way to completely protect against such risks.

Roundhill AMD WeeklyPay™ ETF | SPECIAL TAX RISK  
Prospectus [Line Items]  
Risk [Text Block]

SPECIAL TAX RISK. The Fund intends to qualify annually and to elect to be treated as a regulated investment company under the Internal Revenue Code of 1986, as amended (the “Code”). To qualify for the favorable U.S. federal income tax treatment generally accorded to regulated investment companies, the Fund must, among other things, (i) derive in each taxable year at least 90% of its gross income from dividends, interest, payments with respect to securities loans and gains from the sale or other disposition of stock, securities or foreign currencies or other income derived with respect to its business of investing in such stock, securities or currencies, or net income derived from interests in certain publicly traded partnerships; (ii) diversify its holdings so that, at the end of each quarter of the taxable year, (a) at least 50% of the market value of the Fund’s assets is represented by cash and cash items (including receivables), U.S. government securities, the securities of other regulated investment companies and other securities, with such other securities of any one issuer generally limited for the purposes of this calculation to an amount not greater than 5% of the value of the Fund’s total assets and not greater than 10% of the outstanding voting securities of such issuer, and (b) not more than 25% of the value of its total assets is invested in the securities (other than U.S. government securities or the securities of other regulated investment companies) of any one issuer, or two or more issuers which the Fund controls which are engaged in the same, similar or related trades or businesses, or the securities of one or more of certain publicly traded partnerships; and (iii) distribute at least 90% of its investment company taxable income (which includes, among other items, dividends, interest and net short-term capital gains in excess of net long-term capital losses) and at least 90% of its net tax-exempt interest income each taxable year. There are certain exceptions for failure to qualify if the failure is for reasonable cause or is de minimis, and certain corrective action is taken and certain tax payments are made by the Fund.

 

The authority with regard to swaps entered into by regulated investment companies is unclear both as to the qualification under the income test and the identification of the issuer under the diversification test. The Fund intends to take the position that because the swaps held by the Fund reference securities that the income on the swaps are “other income” from the Fund’s business of investing in stocks and securities. In addition, the Fund intends to manage its investments in the swaps so that neither the exposure to issuer of the referenced security nor the exposure to any one counterparty of the swaps will exceed 25% of the gross value of the Fund’s portfolio at the end of any quarter.

 

If the Fund were to fail to meet the qualifying income test or asset diversification test and fail to qualify as a RIC, it would be taxed in the same manner as an ordinary corporation, and distributions to its shareholders would not be deductible by the Fund in computing its taxable income, which would adversely affect the Fund’s performance.

Roundhill AMD WeeklyPay™ ETF | STRUCTURAL ETF RISKS  
Prospectus [Line Items]  
Risk [Text Block]

STRUCTURAL ETF RISKS. The Fund is an ETF. Accordingly, it is subject to certain risks associated with its unique structure.

 

Market Participants Risk. Only an Authorized Participant may engage in creation or redemption transactions directly with the Fund, and none of those Authorized Participants is obligated to engage in creation and/or redemption transactions. The Fund has a limited number of institutions that may act as Authorized Participants on an agency basis (i.e., on behalf of other market participants). To the extent that Authorized Participants exit the business or are unable to proceed with creation or redemption orders with respect to the Fund and no other Authorized Participant is able to step forward to create or redeem, Fund Shares may be more likely to trade at a premium or discount to NAV and possibly face trading halts or delisting. The Fund may also rely on a small number of third-party market makers to provide a market for the purchase and sale of Fund Shares but such market makers are under no obligation to do so. Decisions by Authorized Participants or market makers to reduce their role or step away from these activities in times of market stress could inhibit the effectiveness of the arbitrage process in maintaining the relationship between the underlying values of the Fund’s portfolio securities and the Fund’s market price. Any trading halt or other problem relating to the trading activity of these market makers or any issues disrupting the Authorized Participants’ ability to proceed with creation and/or redemption orders could result in a dramatic change in the spread between the Fund’s net asset value and the price at which Fund Shares are trading on the Exchange, which could result in a decrease in value of Fund Shares. This reduced effectiveness could result in Fund Shares trading at a premium or discount to net asset value and also in greater than normal intraday bid-ask spreads Fund Shares.

 

Cash Transactions Risk. The Fund currently expects to effect a significant portion of its creations and redemptions for cash, rather than in-kind securities. Paying redemption proceeds in cash rather than through in-kind delivery of portfolio securities may require the Fund to dispose of or sell portfolio securities or other assets at an inopportune time to obtain the cash needed to meet redemption orders. This may cause the Fund to sell a security and recognize a capital gain or loss that might not have been incurred if it had made a redemption in-kind. As a result, the Fund may pay out higher or lower annual capital gains distributions than ETFs that redeem in-kind. The use of cash creations and redemptions may also cause the Fund’s Shares to trade in the market at greater bid-ask spreads or greater premiums or discounts to the Fund’s net asset value (“NAV”). Furthermore, the Fund may not be able to execute cash transactions for creation and redemption purposes at the same price used to determine the Fund’s NAV. To the extent that the maximum additional charge for creation or redemption transactions is insufficient to cover the execution shortfall, the Fund’s performance could be negatively impacted.

 

Costs of Buying and Selling Fund Shares. Due to the costs of buying or selling Fund Shares, including brokerage commissions imposed by brokers and bid/ask spreads, frequent trading of Fund Shares may significantly reduce investment results and an investment in Fund Shares may not be advisable for investors who anticipate regularly making small investments.

 

Premium/Discount Risk. As with all ETFs, Fund Shares may be bought and sold in the secondary market at market prices. The trading prices of Fund Shares in the secondary market may differ from the Fund’s daily NAV per Fund Share and there may be times when the market price of the Fund Shares is more than the NAV per Fund Share (premium) or less than the NAV per Fund Share (discount). If a shareholder purchases Fund Shares at a time when the market price is at a premium to the NAV or sells Fund Shares at a time when the market price is at a discount to the NAV, the shareholder may pay more for, or receive less than, the underlying value of the Fund Shares, respectively. This risk is heightened in times of market volatility or periods of steep market declines.

 

Trading Risks. Although Fund Shares are listed for trading on the Exchange and may be traded on U.S. exchanges other than the Exchange, there can be no assurance that Fund Shares will trade with any volume, or at all, on any stock exchange. In stressed market conditions, the liquidity of Fund Shares may begin to mirror the liquidity of the Fund’s underlying portfolio holdings, which can be significantly less liquid than Fund Shares. Trading in Fund Shares on the Exchange may be halted due to market conditions or for reasons that, in the view of the Exchange, make trading in Fund Shares inadvisable. In addition, trading in Fund Shares on the Exchange is subject to trading halts caused by extraordinary market volatility pursuant to the Exchange’s “circuit breaker” rules. There can be no assurance that the requirements of the Exchange necessary to maintain the listing of the Fund will continue to be met or will remain unchanged.

Roundhill AMD WeeklyPay™ ETF | U.S. GOVERNMENT SECURITIES RISK  
Prospectus [Line Items]  
Risk [Text Block]

U.S. GOVERNMENT SECURITIES RISK. U.S. government securities are subject to interest rate risk but generally do not involve the credit risks associated with investments in other types of debt securities. As a result, the yields available from U.S. government securities are generally lower than the yields available from other debt securities. U.S. government securities are guaranteed only as to the timely payment of interest and the payment of principal when held to maturity.

Roundhill AMD WeeklyPay™ ETF | VALUATION RISK  
Prospectus [Line Items]  
Risk [Text Block]

VALUATION RISK. The Fund may hold securities or other assets that may be valued on the basis of factors other than market quotations. This may occur because the asset or security does not trade on a centralized exchange, or in times of market turmoil or reduced liquidity. There are multiple methods that can be used to value a portfolio holding when market quotations are not readily available. The value established for any portfolio holding at a point in time might differ from what would be produced using a different methodology or if it had been priced using market quotations. Portfolio holdings that are valued using techniques other than market quotations, including “fair valued” assets or securities, may be subject to greater fluctuation in their valuations from one day to the next than if market quotations were used. In addition, there is no assurance that the Fund could sell or close out a portfolio position for the value established for it at any time, and it is possible that the Fund would incur a loss because a portfolio position is sold or closed out at a discount to the valuation established by the Fund at that time. The Fund’s ability to value investments may be impacted by technological issues or errors by pricing services or other third-party service providers.

Roundhill AMD WeeklyPay™ ETF | EQUITY SECURITIES RISK  
Prospectus [Line Items]  
Risk [Text Block]

EQUITY SECURITIES RISK. Equity securities are subject to changes in value, and their values may be more volatile than those of other asset classes. Equity securities prices fluctuate for several reasons, including changes in investors’ perceptions of the financial condition of an issuer or the general condition of the relevant equity market, such as market volatility, or when political or economic events affecting an issuer occur. Common stock prices may be particularly sensitive to rising interest rates, as the cost of capital rises and borrowing costs increase. Common stocks generally subject their holders to more risks than preferred stocks and debt securities because common stockholders’ claims are subordinated to those of holders of preferred stocks and debt securities upon the bankruptcy of the issuer.

Roundhill AMD WeeklyPay™ ETF | SWAP AGREEMENTS RISK  
Prospectus [Line Items]  
Risk [Text Block]

SWAP AGREEMENTS RISK. The Fund will utilize swap agreements to derive its exposure to shares of AMD. Swap agreements may involve greater risks than direct investment in securities as they may be leveraged and are subject to credit risk, counterparty risk and valuation risk. A swap agreement could result in losses if the underlying reference or asset does not perform as anticipated. In addition, many swaps trade over-the-counter and may be considered illiquid. It may not be possible for the Fund to liquidate a swap position at an advantageous time or price, which may result in significant losses.

Roundhill AMD WeeklyPay™ ETF | REGULATED INVESTMENT COMPANY TAX RISKS  
Prospectus [Line Items]  
Risk [Text Block]

REGULATED INVESTMENT COMPANY TAX RISKS. The Fund intends to qualify annually and to elect to be treated as a regulated investment company under the Internal Revenue Code of 1986, as amended (the “Code”). To qualify for the favorable U.S. federal income tax treatment generally accorded to regulated investment companies, the Fund must, among other things, (i) derive in each taxable year at least 90% of its gross income from dividends, interest, payments with respect to securities loans and gains from the sale or other disposition of stock, securities or foreign currencies or other income derived with respect to its business of investing in such stock, securities or currencies, or net income derived from interests in certain publicly traded partnerships; (ii) diversify its holdings so that, at the end of each quarter of the taxable year, (a) at least 50% of the market value of the Fund’s assets is represented by cash and cash items (including receivables), U.S. government securities, the securities of other regulated investment companies and other securities, with such other securities of any one issuer generally limited for the purposes of this calculation to an amount not greater than 5% of the value of the Fund’s total assets and not greater than 10% of the outstanding voting securities of such issuer, and (b) not more than 25% of the value of its total assets is invested in the securities (other than U.S. government securities or the securities of other regulated investment companies) of any one issuer, or two or more issuers which the Fund controls which are engaged in the same, similar or related trades or businesses, or the securities of one or more of certain publicly traded partnerships; and (iii) distribute at least 90% of its investment company taxable income (which includes, among other items, dividends, interest and net short-term capital gains in excess of net long-term capital losses) and at least 90% of its net tax-exempt interest income each taxable year. There are certain exceptions for failure to qualify if the failure is for reasonable cause or is de minimis, and certain corrective action is taken and certain tax payments are made by the Fund.

 

If the Fund were to fail to meet the qualifying income test or asset diversification test and fail to qualify as a RIC, it would be taxed in the same manner as an ordinary corporation, and distributions to its shareholders would not be deductible by the Fund in computing its taxable income, which would adversely affect the Fund’s performance.

Roundhill AMD WeeklyPay™ ETF | LARGE SHAREHOLDER RISK  
Prospectus [Line Items]  
Risk [Text Block]

LARGE SHAREHOLDER RISK. Certain shareholders, including affiliated funds advised by the Adviser, may from time to time own a significant portion of the Fund’s shares. In addition, a third-party investor, the Adviser or an affiliate of the Adviser (“Affiliate”), an authorized participant, a market maker, or another entity may invest in the Fund and hold its investment for a limited period solely to facilitate the commencement of the Fund or to help the Fund achieve a specified size or scale. There can be no assurance that any large shareholder will not redeem its investment, that the size of the Fund will be maintained at such levels, or that the Fund will continue to meet applicable listing requirements. Redemptions by large shareholders could have a significant negative impact on the Fund. In addition, transactions by large shareholders may account for a large percentage of the trading volume on the Fund’s listing exchange and may, therefore, have a material upward or downward effect on the market price of the shares.

 

To the extent that a significant percentage of the Fund’s shares are owned or controlled by a small number of account shareholders (or a single account shareholder), including funds or accounts over which the Adviser or an Affiliate has investment discretion, the Fund is subject to the risk that those shareholders may purchase or redeem Fund shares in significant amounts rapidly or unexpectedly, including as a result of an asset allocation decision made by the Adviser or an Affiliate. This may adversely affect the Fund’s performance if the Adviser is forced to sell portfolio securities or invest cash when it would not otherwise choose to do so. Redemptions of a large number of shares may affect the liquidity of the Fund’s portfolio, increase the Fund’s transaction costs, and accelerate the realization of taxable income and/or gains. In addition, a large redemption could result in the Fund’s current expenses being allocated over a smaller asset base, leading to an increase in the Fund’s gross expense ratio. Large purchases of the Fund’s shares may also adversely affect the Fund’s performance to the extent that the Fund is delayed in investing new cash or otherwise maintains a larger cash position than it ordinarily would, particularly if the Fund accepts cash for an order for the purchase of creation units of the Fund’s shares.

Roundhill AMD WeeklyPay™ ETF | AMD INVESTING RISKS  
Prospectus [Line Items]  
Risk [Text Block]

AMD INVESTING RISKS. The Fund will have significant exposure to AMD through its investments in swap agreements that utilize AMD as the reference asset. Accordingly, the Fund will subject to the risks of AMD, set forth below.

 

AMD ISSUER-SPECIFIC RISKS. Issuer-specific attributes may cause an investment held by the Fund to be more volatile than the market generally. The value of an individual security or particular type of security may be more volatile than the market as a whole and may perform differently from the value of the market as a whole. As of the date of this prospectus, in addition to the risks associated with companies in the technology sector, AMD faces risks related to: global and economic conditions; market disrupting events, such as wars, natural disasters and public health issues; highly competitive global demand and rapidly changing technology; managing the frequent introductions and transitions of products and services; the outsourced manufacturing and logistical services provided by partners, many of which are located outside of the United States; the ability to obtain components in sufficient quantities on commercially reasonable terms for its products; potential design and manufacturing defects in its products and services; write-downs on the value of the company’s inventory and other assets; the reliance on access to third-party intellectual property and on third-party software developers; ability to obtain or create digital content that appeals to customers; the ability to retain and hire highly skilled employees, including key personnel; the performance of carriers, wholesalers, retailers and other resellers; information technology system failures and network disruptions; losses or unauthorized access to or releases of confidential information; investments in new business strategies may disrupt the current activities, changing needs and costs related to the company’s retail stores; and legal and regulatory compliance risks.

 

INDIRECT INVESTMENT RISK. Advanced Microdevices, Inc. is not affiliated with the Trust, the Fund, the Adviser, the Sub-Adviser or any affiliates thereof and is not involved with this offering in any way, and has no obligation to consider the Fund in taking any corporate actions that might affect the value of the Fund. The Trust, the Fund, the Adviser, the Sub-Adviser or any affiliate are not responsible for the performance of AMD and make no representation as to the performance of AMD. Investing in the Fund is not equivalent to investing in AMD. Fund shareholders will not have voting rights or rights to receive dividends or other distributions or any other rights with respect to AMD.

 

INFORMATION TECHNOLOGY COMPANIES RISK. Information technology companies face intense competition, both domestically and internationally, which may have an adverse effect on profit margins. Like other technology companies, information technology companies may have limited product lines, markets, financial resources or personnel. The products of information technology companies may face obsolescence due to rapid technological developments, frequent new product introduction, unpredictable changes in growth rates and competition for the services of qualified personnel. Companies in the information technology sector are heavily dependent on patent and intellectual property rights. The loss or impairment of these rights may adversely affect the profitability of these companies. Information technology companies are facing increased government and regulatory scrutiny and may be subject to adverse government or regulatory action.

 

LARGE CAPITALIZATION COMPANIES RISK. Large capitalization companies may be less able than smaller capitalization companies to adapt to changing market conditions. Large capitalization companies may be more mature and subject to more limited growth potential compared with smaller capitalization companies. During different market cycles, the performance of large capitalization companies has trailed the overall performance of the broader securities markets.

 

SEMICONDUCTOR COMPANIES RISK. Semiconductor companies face intense competition, both domestically and internationally, and such competition may have an adverse effect on profit margins. Semiconductor companies may have limited product lines, markets, financial resources or personnel. Semiconductor companies’ supply chain and operations are dependent on the availability of materials that meet exacting standards and the use of third parties to provide components and services. Semiconductor companies may rely on a limited number of suppliers, or upon suppliers in a single location, for certain materials, equipment or tools. Finding and qualifying alternate or additional suppliers can be a lengthy process that can cause production delays or impose unforeseen costs, and such alternatives may not be available at all. Production can be disrupted by the unavailability of resources, such as water, silicon, electricity, gases and other materials. Suppliers may also increase prices or encounter cybersecurity or other issues that can disrupt production or increase production costs. The products of semiconductor companies may face obsolescence due to rapid technological developments and frequent new product introduction, unpredictable changes in growth rates and competition for the services of qualified personnel. Capital equipment expenditures could be substantial, and equipment generally suffers from rapid obsolescence. Companies in the semiconductor industry are heavily dependent on patent and intellectual property rights. The loss or impairment of these rights, would adversely affect the profitability of these companies.

 

UNITED STATES RISK. Certain changes in the U.S. economy, such as when the U.S. economy weakens or when its financial markets decline, may have an adverse effect on the securities to which the Fund has exposure.

NON-DIVERSIFICATION RISK. As a “non-diversified” fund, the Fund may hold a smaller number of portfolio securities than many other funds. To the extent the Fund invests in a relatively small number of issuers, a decline in the market value of a particular security held by the Fund may affect its value more than if it invested in a larger number of issuers. The value of the Fund Shares may be more volatile than the values of shares of more diversified funds.

Roundhill AMZN WeeklyPay™ ETF | MARKET RISK  
Prospectus [Line Items]  
Risk [Text Block]

MARKET RISK. Market risk is the risk that a particular investment, or Fund Shares in general, may fall in value. Securities are subject to market fluctuations caused by real or perceived adverse economic, political, and regulatory factors or market developments, changes in interest rates, disruptions to trade, impositions of tariffs and perceived trends in securities prices. Fund Shares could decline in value or underperform other investments. In addition, local, regional or global events such as war, acts of terrorism, market manipulation, government defaults, government shutdowns, regulatory actions, political changes, diplomatic developments, the imposition of sanctions and other similar measures, spread of infectious diseases or other public health issues, recessions, natural disasters, or other events could have a significant negative impact on the Fund and its investments. Any of such circumstances could have a materially negative impact on the value of Fund Shares, the liquidity of an investment, and may result in increased market volatility. During any such events, Fund Shares may trade at increased premiums or discounts to their net asset value, the bid/ask spread on Fund Shares may widen and the returns on investment may fluctuate.

Roundhill AMZN WeeklyPay™ ETF | LIQUIDITY RISK  
Prospectus [Line Items]  
Risk [Text Block]

LIQUIDITY RISK. The market for swap agreements that reference AMZN shares may be subject to periods of illiquidity. During such times it may be difficult or impossible to buy or sell a position at the desired price. Market disruptions or volatility can also make it difficult to find a counterparty willing to transact at a reasonable price and sufficient size. Illiquid markets may cause losses, which could be significant. The large size of the positions which the Fund may acquire increases the risk of illiquidity, may make its positions more difficult to liquidate, and may increase the losses incurred while trying to do so. Such large positions also may impact the price of swap agreements on AMZN shares.

Roundhill AMZN WeeklyPay™ ETF | ACTIVE MANAGEMENT RISK  
Prospectus [Line Items]  
Risk [Text Block]

ACTIVE MANAGEMENT RISK. The Fund is actively-managed and its performance reflects investment decisions that the Adviser and/or Sub-Adviser makes for the Fund. Such judgments about the Fund’s investments may prove to be incorrect. If the investments selected and the strategies employed by the Fund fail to produce the intended results, the Fund could underperform as compared to other funds with similar investment objectives and/or strategies, or could have negative returns.

Roundhill AMZN WeeklyPay™ ETF | ACTIVE MARKET RISK  
Prospectus [Line Items]  
Risk [Text Block]

ACTIVE MARKET RISK. Although Fund Shares are listed for trading on the Exchange, there can be no assurance that an active trading market for Fund Shares will develop or be maintained. Fund Shares trade on the Exchange at market prices that may be below, at or above the Fund’s net asset value. Securities, including Fund Shares, are subject to market fluctuations and liquidity constraints that may be caused by such factors as economic, political, or regulatory developments, changes in interest rates, and/or perceived trends in securities prices. Fund Shares could decline in value or underperform other investments.

Roundhill AMZN WeeklyPay™ ETF | ASSET CLASS RISK

Risk [Text Block]

CONCENTRATION RISK. The Fund is susceptible to an increased risk of loss, including losses due to adverse events that affect the Fund’s investments more than the market as a whole, to the extent that the Fund’s investments are concentrated in investments that provide exposure to AMZN and the industry to which it is assigned.

Roundhill AMZN WeeklyPay™ ETF | COUNTERPARTY RISK  
Prospectus [Line Items]  
Risk [Text Block]

COUNTERPARTY RISK. Fund transactions involving a counterparty are subject to the risk that the counterparty will not fulfill its obligation to the Fund. Counterparty risk may arise because of the counterparty’s financial condition (i.e., financial difficulties, bankruptcy, or insolvency), market activities and developments, or other reasons, whether foreseen or not. A counterparty’s inability to fulfill its obligation may result in significant financial loss to the Fund. The Fund may be unable to recover its investment from the counterparty or may obtain a limited recovery, and/or recovery may be delayed.

Risk [Text Block]

CREDIT RISK. An issuer or other obligated party of a debt security may be unable or unwilling to make dividend, interest and/or principal payments when due. In addition, the value of a debt security may decline because of concerns about the issuer’s ability or unwillingness to make such payments.

Roundhill AMZN WeeklyPay™ ETF | CYBERSECURITY RISK  
Prospectus [Line Items]  
Risk [Text Block]

CYBERSECURITY RISK. Failures or breaches of the electronic systems of the Fund, the Fund’s adviser, sub-adviser, distributor and other service providers, market makers, Authorized Participants or the issuers of securities in which the Fund invests have the ability to cause disruptions, negatively impact the Fund’s business operations and/or potentially result in financial losses to the Fund and its shareholders. While the Fund has established business continuity plans and risk management systems seeking to address system breaches or failures, there are inherent limitations in such plans and systems. Furthermore, the Fund cannot control the cybersecurity plans and systems of the Fund’s other service providers, market makers, Authorized Participants or issuers of securities in which the Fund invests.

Roundhill AMZN WeeklyPay™ ETF | DEBT SECURITIES RISK  
Prospectus [Line Items]  
Risk [Text Block]

DEBT SECURITIES RISK. Investments in debt securities subject the holder to the credit risk of the issuer. Credit risk refers to the possibility that the issuer or other obligor of a security will not be able or willing to make payments of interest and principal when due. Generally, the value of debt securities will change inversely with changes in interest rates. To the extent that interest rates rise, certain underlying obligations may be paid off substantially slower than originally anticipated and the value of those securities may fall sharply. During periods of falling interest rates, the income received by the Fund may decline. If the principal on a debt security is prepaid before expected, the prepayments of principal may have to be reinvested in obligations paying interest at lower rates. Debt securities generally do not trade on a securities exchange making them generally less liquid and more difficult to value than common stock.

Roundhill AMZN WeeklyPay™ ETF | DERIVATIVES RISK  
Prospectus [Line Items]  
Risk [Text Block]

DERIVATIVES RISK. The use of derivative instruments involves risks different from, or possibly greater than, the risks associated with investing directly in securities and other traditional investments. These risks include: (i) the risk that the counterparty to a derivative transaction may not fulfill its contractual obligations; (ii) risk of mispricing or improper valuation; and (iii) the risk that changes in the value of the derivative may not correlate perfectly with the underlying asset. Derivative prices are highly volatile and may fluctuate substantially during a short period of time. Such prices are influenced by numerous factors that affect the markets, including, but not limited to: changing supply and demand relationships; government programs and policies; national and international political and economic events, changes in interest rates, inflation and deflation and changes in supply and demand relationships. Trading derivative instruments involves risks different from, or possibly greater than, the risks associated with investing directly in securities. Derivative contracts ordinarily have leverage inherent in their terms. The use of leverage may cause the Fund to liquidate portfolio positions when it would not be advantageous to do so in order to satisfy its obligations or to meet regulatory or contractual requirements for derivatives. The use of derivatives can magnify potential for gain or loss and, therefore, amplify the effects of market volatility on share price.

Roundhill AMZN WeeklyPay™ ETF | DISTRIBUTION TAX RISK  
Prospectus [Line Items]  
Risk [Text Block]

DISTRIBUTION TAX RISK. The Fund currently expects to make distributions on a weekly basis. Such frequent distributions may expose investors to increased tax liabilities. However, these distributions may exceed the Fund’s income and gains for the Fund’s taxable year. Distributions in excess of the Fund’s current and accumulated earnings and profits will be treated as a return of capital. A return of capital distribution generally will not be taxable but will reduce the shareholder’s cost basis and will result in a higher capital gain or lower capital loss when those Fund Shares on which the distribution was received are sold. Once a Fund shareholder’s cost basis is reduced to zero, further distributions will be treated as capital gain if the Fund shareholder holds Fund Shares as capital assets. Additionally, any capital returned through distributions will be distributed after payment of Fund fees and expenses. Because a portion of the Fund’s distributions may consist of return of capital, the Fund may not be an appropriate investment for investors who do not want their principal investment in the Fund to decrease over time or who do not wish to receive return of capital in a given period. In the event that a shareholder purchases Fund Shares shortly before a distribution by the Fund, the entire distribution may be taxable to the shareholder even though a portion of the distribution effectively represents a return of the purchase price.

Roundhill AMZN WeeklyPay™ ETF | ETF RISK  
Prospectus [Line Items]  
Risk [Text Block]

ETF RISK. The Fund may invest in ETFs. The value of an ETF held by the Fund will fluctuate over time based on fluctuations in the values of the assets held by the ETF, which may be affected by changes in general economic conditions, expectations for future growth and profits, interest rates and the supply and demand for those assets. When the Fund invests in an ETF, it will bear a proportionate share of the ETF’s expenses. Brokerage, tax and other expenses may negatively impact the performance of the ETF and, in turn, the value of the Fund Shares. An ETF that tracks an index may not exactly match the performance of the index due to cash drag, differences between the portfolio of the ETF and the components of the index, expenses and other factors.

Roundhill AMZN WeeklyPay™ ETF | INFLATION RISK  
Prospectus [Line Items]  
Risk [Text Block]

INFLATION RISK. Inflation risk is the risk that the value of assets or income from investments will be less in the future as inflation decreases the value of money. As inflation increases, the present value of the Fund’s assets and distributions may decline. This risk is more prevalent with respect to fixed income securities held by the Fund.

Roundhill AMZN WeeklyPay™ ETF | Interest Rate Risk [Member]  
Prospectus [Line Items]  
Risk [Text Block]

INTEREST RATE RISK. Interest rate risk is the risk that the value of the debt securities in the Fund’s portfolio will decline because of rising market interest rates. Interest rate risk is generally lower for shorter term debt securities and higher for longer-term debt securities. Duration is a reasonably accurate measure of a debt security’s price sensitivity to changes in interest rates and a common measure of interest rate risk. Duration measures a debt security’s expected life on a present value basis, taking into account the debt security’s yield, interest payments and final maturity. In general, duration represents the expected percentage change in the value of a security for an immediate 1% change in interest rates. For example, the price of a debt security with a three-year duration would be expected to drop by approximately 3% in response to a 1% increase in interest rates. Therefore, prices of debt securities with shorter durations tend to be less sensitive to interest rate changes than debt securities with longer durations. As the value of a debt security changes over time, so will its duration.

Roundhill AMZN WeeklyPay™ ETF | LEGISLATION AND LITIGATION RISK  
Prospectus [Line Items]  
Risk [Text Block]

LEGISLATION AND LITIGATION RISK. Legislation or litigation that affects the value of assets or securities held by the Fund may reduce the value of the Fund. From time to time, various legislative initiatives are proposed that may have a negative impact on certain assets or securities in which the Fund invests. In addition, litigation regarding any of the assets or securities owned by the Fund may negatively impact the value of the Shares. Such legislation or litigation may cause the Fund to lose value or may result in higher portfolio turnover if the Adviser determines to sell such a holding.

Roundhill AMZN WeeklyPay™ ETF | LEVERAGE RISK  
Prospectus [Line Items]  
Risk [Text Block]

LEVERAGE RISK. The Fund obtains investment exposure in excess of its net assets by utilizing leverage and may lose more money in market conditions that are adverse to its investment objectives than a fund that does not utilize leverage. An investment in the Fund is exposed to the risk that a decline in the weekly performance of shares of AMZN will be magnified. This means that an investment in the Fund will be reduced by an amount equal to 1.2% for every 1% weekly decline in the market value of the AMZN shares, not including the costs of financing leverage and other operating expenses, which would further reduce its value. The Fund could theoretically lose an amount greater than its net assets in the event the market value of AMZN shares decline more than 83.33% over a calendar week. Leverage will also have the effect of magnifying any differences in the Fund’s correlation with AMZN shares.

Roundhill AMZN WeeklyPay™ ETF | MONEY MARKET INSTRUMENTS RISK  
Prospectus [Line Items]  
Risk [Text Block]

MONEY MARKET INSTRUMENTS RISK. The value of money market instruments may be affected by changing interest rates and by changes in the credit ratings of the investments. If a significant amount of the Fund’s assets are invested in money market instruments, it will be more difficult for the Fund to achieve its investment objectives. An investment in a money market fund is not insured or guaranteed by the FDIC or any other government agency. It is possible to lose money by investing in a money market fund.

Roundhill AMZN WeeklyPay™ ETF | OPERATIONAL RISK  
Prospectus [Line Items]  
Risk [Text Block]

OPERATIONAL RISK. The Fund is subject to risks arising from various operational factors, including, but not limited to, human error, processing and communication errors, errors of the Fund’s service providers, counterparties or other third-parties, failed or inadequate processes and technology or systems failures. The Fund relies on third-parties for a range of services, including custody. Any delay or failure relating to engaging or maintaining such service providers may affect the Fund’s ability to meet its investment objectives. Although the Fund and the Adviser seek to reduce these operational risks through controls and procedures, there is no way to completely protect against such risks.

Roundhill AMZN WeeklyPay™ ETF | SPECIAL TAX RISK  
Prospectus [Line Items]  
Risk [Text Block]

SPECIAL TAX RISK. The Fund intends to qualify annually and to elect to be treated as a regulated investment company under the Internal Revenue Code of 1986, as amended (the “Code”). To qualify for the favorable U.S. federal income tax treatment generally accorded to regulated investment companies, the Fund must, among other things, (i) derive in each taxable year at least 90% of its gross income from dividends, interest, payments with respect to securities loans and gains from the sale or other disposition of stock, securities or foreign currencies or other income derived with respect to its business of investing in such stock, securities or currencies, or net income derived from interests in certain publicly traded partnerships; (ii) diversify its holdings so that, at the end of each quarter of the taxable year, (a) at least 50% of the market value of the Fund’s assets is represented by cash and cash items (including receivables), U.S. government securities, the securities of other regulated investment companies and other securities, with such other securities of any one issuer generally limited for the purposes of this calculation to an amount not greater than 5% of the value of the Fund’s total assets and not greater than 10% of the outstanding voting securities of such issuer, and (b) not more than 25% of the value of its total assets is invested in the securities (other than U.S. government securities or the securities of other regulated investment companies) of any one issuer, or two or more issuers which the Fund controls which are engaged in the same, similar or related trades or businesses, or the securities of one or more of certain publicly traded partnerships; and (iii) distribute at least 90% of its investment company taxable income (which includes, among other items, dividends, interest and net short-term capital gains in excess of net long-term capital losses) and at least 90% of its net tax-exempt interest income each taxable year. There are certain exceptions for failure to qualify if the failure is for reasonable cause or is de minimis, and certain corrective action is taken and certain tax payments are made by the Fund.

 

The authority with regard to swaps entered into by regulated investment companies is unclear both as to the qualification under the income test and the identification of the issuer under the diversification test. The Fund intends to take the position that because the swaps held by the Fund reference securities that the income on the swaps are “other income” from the Fund’s business of investing in stocks and securities. In addition, the Fund intends to manage its investments in the swaps so that neither the exposure to issuer of the referenced security nor the exposure to any one counterparty of the swaps will exceed 25% of the gross value of the Fund’s portfolio at the end of any quarter.

 

If the Fund were to fail to meet the qualifying income test or asset diversification test and fail to qualify as a RIC, it would be taxed in the same manner as an ordinary corporation, and distributions to its shareholders would not be deductible by the Fund in computing its taxable income, which would adversely affect the Fund’s performance.

Roundhill AMZN WeeklyPay™ ETF | STRUCTURAL ETF RISKS  
Prospectus [Line Items]  
Risk [Text Block]

STRUCTURAL ETF RISKS. The Fund is an ETF. Accordingly, it is subject to certain risks associated with its unique structure.

 

Market Participants Risk. Only an Authorized Participant may engage in creation or redemption transactions directly with the Fund, and none of those Authorized Participants is obligated to engage in creation and/or redemption transactions. The Fund has a limited number of institutions that may act as Authorized Participants on an agency basis (i.e., on behalf of other market participants). To the extent that Authorized Participants exit the business or are unable to proceed with creation or redemption orders with respect to the Fund and no other Authorized Participant is able to step forward to create or redeem, Fund Shares may be more likely to trade at a premium or discount to NAV and possibly face trading halts or delisting. The Fund may also rely on a small number of third-party market makers to provide a market for the purchase and sale of Fund Shares but such market makers are under no obligation to do so. Decisions by Authorized Participants or market makers to reduce their role or step away from these activities in times of market stress could inhibit the effectiveness of the arbitrage process in maintaining the relationship between the underlying values of the Fund’s portfolio securities and the Fund’s market price. Any trading halt or other problem relating to the trading activity of these market makers or any issues disrupting the Authorized Participants’ ability to proceed with creation and/or redemption orders could result in a dramatic change in the spread between the Fund’s net asset value and the price at which Fund Shares are trading on the Exchange, which could result in a decrease in value of Fund Shares. This reduced effectiveness could result in Fund Shares trading at a premium or discount to net asset value and also in greater than normal intraday bid-ask spreads Fund Shares.

 

Cash Transactions Risk. The Fund currently expects to effect a significant portion of its creations and redemptions for cash, rather than in-kind securities. Paying redemption proceeds in cash rather than through in-kind delivery of portfolio securities may require the Fund to dispose of or sell portfolio securities or other assets at an inopportune time to obtain the cash needed to meet redemption orders. This may cause the Fund to sell a security and recognize a capital gain or loss that might not have been incurred if it had made a redemption in-kind. As a result, the Fund may pay out higher or lower annual capital gains distributions than ETFs that redeem in-kind. The use of cash creations and redemptions may also cause the Fund’s Shares to trade in the market at greater bid-ask spreads or greater premiums or discounts to the Fund’s net asset value (“NAV”). Furthermore, the Fund may not be able to execute cash transactions for creation and redemption purposes at the same price used to determine the Fund’s NAV. To the extent that the maximum additional charge for creation or redemption transactions is insufficient to cover the execution shortfall, the Fund’s performance could be negatively impacted.

 

Costs of Buying and Selling Fund Shares. Due to the costs of buying or selling Fund Shares, including brokerage commissions imposed by brokers and bid/ask spreads, frequent trading of Fund Shares may significantly reduce investment results and an investment in Fund Shares may not be advisable for investors who anticipate regularly making small investments.

 

Premium/Discount Risk. As with all ETFs, Fund Shares may be bought and sold in the secondary market at market prices. The trading prices of Fund Shares in the secondary market may differ from the Fund’s daily NAV per Fund Share and there may be times when the market price of the Fund Shares is more than the NAV per Fund Share (premium) or less than the NAV per Fund Share (discount). If a shareholder purchases Fund Shares at a time when the market price is at a premium to the NAV or sells Fund Shares at a time when the market price is at a discount to the NAV, the shareholder may pay more for, or receive less than, the underlying value of the Fund Shares, respectively. This risk is heightened in times of market volatility or periods of steep market declines.

 

Trading Risks. Although Fund Shares are listed for trading on the Exchange and may be traded on U.S. exchanges other than the Exchange, there can be no assurance that Fund Shares will trade with any volume, or at all, on any stock exchange. In stressed market conditions, the liquidity of Fund Shares may begin to mirror the liquidity of the Fund’s underlying portfolio holdings, which can be significantly less liquid than Fund Shares. Trading in Fund Shares on the Exchange may be halted due to market conditions or for reasons that, in the view of the Exchange, make trading in Fund Shares inadvisable. In addition, trading in Fund Shares on the Exchange is subject to trading halts caused by extraordinary market volatility pursuant to the Exchange’s “circuit breaker” rules. There can be no assurance that the requirements of the Exchange necessary to maintain the listing of the Fund will continue to be met or will remain unchanged.

Roundhill AMZN WeeklyPay™ ETF | U.S. GOVERNMENT SECURITIES RISK  
Prospectus [Line Items]  
Risk [Text Block]

U.S. GOVERNMENT SECURITIES RISK. U.S. government securities are subject to interest rate risk but generally do not involve the credit risks associated with investments in other types of debt securities. As a result, the yields available from U.S. government securities are generally lower than the yields available from other debt securities. U.S. government securities are guaranteed only as to the timely payment of interest and the payment of principal when held to maturity.

Roundhill AMZN WeeklyPay™ ETF | VALUATION RISK  
Prospectus [Line Items]  
Risk [Text Block]

VALUATION RISK. The Fund may hold securities or other assets that may be valued on the basis of factors other than market quotations. This may occur because the asset or security does not trade on a centralized exchange, or in times of market turmoil or reduced liquidity. There are multiple methods that can be used to value a portfolio holding when market quotations are not readily available. The value established for any portfolio holding at a point in time might differ from what would be produced using a different methodology or if it had been priced using market quotations. Portfolio holdings that are valued using techniques other than market quotations, including “fair valued” assets or securities, may be subject to greater fluctuation in their valuations from one day to the next than if market quotations were used. In addition, there is no assurance that the Fund could sell or close out a portfolio position for the value established for it at any time, and it is possible that the Fund would incur a loss because a portfolio position is sold or closed out at a discount to the valuation established by the Fund at that time. The Fund’s ability to value investments may be impacted by technological issues or errors by pricing services or other third-party service providers.

Roundhill AMZN WeeklyPay™ ETF | EQUITY SECURITIES RISK  
Prospectus [Line Items]  
Risk [Text Block]

EQUITY SECURITIES RISK. Equity securities are subject to changes in value, and their values may be more volatile than those of other asset classes. Equity securities prices fluctuate for several reasons, including changes in investors’ perceptions of the financial condition of an issuer or the general condition of the relevant equity market, such as market volatility, or when political or economic events affecting an issuer occur. Common stock prices may be particularly sensitive to rising interest rates, as the cost of capital rises and borrowing costs increase. Common stocks generally subject their holders to more risks than preferred stocks and debt securities because common stockholders’ claims are subordinated to those of holders of preferred stocks and debt securities upon the bankruptcy of the issuer.

Roundhill AMZN WeeklyPay™ ETF | SWAP AGREEMENTS RISK  
Prospectus [Line Items]  
Risk [Text Block]

SWAP AGREEMENTS RISK. The Fund will utilize swap agreements to derive its exposure to shares of AMZN. Swap agreements may involve greater risks than direct investment in securities as they may be leveraged and are subject to credit risk, counterparty risk and valuation risk. A swap agreement could result in losses if the underlying reference or asset does not perform as anticipated. In addition, many swaps trade over-the-counter and may be considered illiquid. It may not be possible for the Fund to liquidate a swap position at an advantageous time or price, which may result in significant losses.

Roundhill AMZN WeeklyPay™ ETF | REGULATED INVESTMENT COMPANY TAX RISKS  
Prospectus [Line Items]  
Risk [Text Block]

REGULATED INVESTMENT COMPANY TAX RISKS. The Fund intends to qualify annually and to elect to be treated as a regulated investment company under the Internal Revenue Code of 1986, as amended (the “Code”). To qualify for the favorable U.S. federal income tax treatment generally accorded to regulated investment companies, the Fund must, among other things, (i) derive in each taxable year at least 90% of its gross income from dividends, interest, payments with respect to securities loans and gains from the sale or other disposition of stock, securities or foreign currencies or other income derived with respect to its business of investing in such stock, securities or currencies, or net income derived from interests in certain publicly traded partnerships; (ii) diversify its holdings so that, at the end of each quarter of the taxable year, (a) at least 50% of the market value of the Fund’s assets is represented by cash and cash items (including receivables), U.S. government securities, the securities of other regulated investment companies and other securities, with such other securities of any one issuer generally limited for the purposes of this calculation to an amount not greater than 5% of the value of the Fund’s total assets and not greater than 10% of the outstanding voting securities of such issuer, and (b) not more than 25% of the value of its total assets is invested in the securities (other than U.S. government securities or the securities of other regulated investment companies) of any one issuer, or two or more issuers which the Fund controls which are engaged in the same, similar or related trades or businesses, or the securities of one or more of certain publicly traded partnerships; and (iii) distribute at least 90% of its investment company taxable income (which includes, among other items, dividends, interest and net short-term capital gains in excess of net long-term capital losses) and at least 90% of its net tax-exempt interest income each taxable year. There are certain exceptions for failure to qualify if the failure is for reasonable cause or is de minimis, and certain corrective action is taken and certain tax payments are made by the Fund.

 

If the Fund were to fail to meet the qualifying income test or asset diversification test and fail to qualify as a RIC, it would be taxed in the same manner as an ordinary corporation, and distributions to its shareholders would not be deductible by the Fund in computing its taxable income, which would adversely affect the Fund’s performance.

Roundhill AMZN WeeklyPay™ ETF | LARGE SHAREHOLDER RISK  
Prospectus [Line Items]  
Risk [Text Block]

LARGE SHAREHOLDER RISK. Certain shareholders, including affiliated funds advised by the Adviser, may from time to time own a significant portion of the Fund’s shares. In addition, a third-party investor, the Adviser or an affiliate of the Adviser (“Affiliate”), an authorized participant, a market maker, or another entity may invest in the Fund and hold its investment for a limited period solely to facilitate the commencement of the Fund or to help the Fund achieve a specified size or scale. There can be no assurance that any large shareholder will not redeem its investment, that the size of the Fund will be maintained at such levels, or that the Fund will continue to meet applicable listing requirements. Redemptions by large shareholders could have a significant negative impact on the Fund. In addition, transactions by large shareholders may account for a large percentage of the trading volume on the Fund’s listing exchange and may, therefore, have a material upward or downward effect on the market price of the shares.

Roundhill AMZN WeeklyPay™ ETF | AMZN INVESTING RISKS  
Prospectus [Line Items]  
Risk [Text Block]

AMZN INVESTING RISKS. The Fund will have significant exposure to AMZN through its investments in swap agreements that utilize AMZN as the reference asset. Accordingly, the Fund will subject to the risks of AMZN, set forth below.

 

AMZN ISSUER-SPECIFIC RISKS. Issuer-specific attributes may cause an investment held by the Fund to be more volatile than the market generally. The value of an individual security or particular type of security may be more volatile than the market as a whole and may perform differently from the value of the market as a whole. As of the date of this prospectus, in addition to the risks associated with companies in the consumer discretionary sector, Amazon.com, Inc. faces risks associated with: intense competition across different industries, including physical, e-commerce omnichannel retail, e-commerce services, web and infrastructure computing services, electronic devices, digital content, advertising, grocery, and transportation and logistics services; the expansion into new products, services, technologies and geographic regions; its international activities; the variability in the demand for its products and services; fraudulent and unlawful activities of sellers; intellectual property rights; foreign exchange risk; expansion of global operations, significant fluctuations in operating results and growth rate; successfully optimizing and operating its fulfilment network and data centers; data loss or other security breaches; system interruption and lack of redundancy; maintaining key senior management personnel and the ability to hire and retain highly skilled and other key personnel; maintaining good supplier relationships, including content and technology licensors; commercial agreements and business relationships expose the company to greater liability; the success of acquisitions or joint ventures or other investments; significant inventory disruptions due to seasonality, obsolescence, defective merchandise, changing consumer spending and interests and other factors; ever changing regulations and compliance related to the various payments accepted; its rapidly evolving and expanding business model; and legal, regulatory, tax liability, and litigation issues.

 

CONSUMER DISCRETIONARY COMPANIES RISK. The success of consumer product manufacturers and retailers is tied closely to the performance of domestic and international economies, interest rates, exchange rates, supply chains, competition, consumer confidence, changes in demographics and consumer preferences. Companies in the consumer discretionary sector depend heavily on disposable household income and consumer spending, and may be strongly affected by social trends and marketing campaigns. These companies may be subject to severe competition, which may have an adverse impact on their profitability.

 

INDIRECT INVESTMENT RISK. Amazon.com, Inc. is not affiliated with the Trust, the Fund, the Adviser, the Sub-Adviser or any affiliates thereof and is not involved with this offering in any way, and has no obligation to consider the Fund in taking any corporate actions that might affect the value of the Fund. The Trust, the Fund, the Adviser, the Sub-Adviser or any affiliate are not responsible for the performance of AMZN and make no representation as to the performance of AMZN. Investing in the Fund is not equivalent to investing in AMZN. Fund shareholders will not have voting rights or rights to receive dividends or other distributions or any other rights with respect to AMZN.

 

LARGE CAPITALIZATION COMPANIES RISK. Large capitalization companies may be less able than smaller capitalization companies to adapt to changing market conditions. Large capitalization companies may be more mature and subject to more limited growth potential compared with smaller capitalization companies. During different market cycles, the performance of large capitalization companies has trailed the overall performance of the broader securities markets.

 

RETAIL COMPANIES RISK. Companies involved in retail may be affected by the performance of the domestic and international economy, interest rates, rates of inflation, exchange rates, competition, consumer confidence and reputational damage. The success of companies involved in retail depends heavily on disposable household income and consumer spending, and changes in demographics and consumer preferences can affect the success of retail companies. Certain retail companies have historically been subject to significant seasonal and quarterly variations. The success of retail companies may be strongly affected by fads, marketing campaigns and other factors affecting supply and demand and a retail company’s success can be tied to its ability to anticipate changing consumer tastes. These companies may be subject to severe competition, which may have an adverse impact on their profitability.

 

Certain business segments of retail companies are highly cyclical, which may cause the operating results of such retail companies to vary significantly. Retail companies may be dependent on outside financing, which may be difficult to obtain. Many of these companies are dependent on third party suppliers and distribution systems and purchase merchandise both directly from brand owners and indirectly from retailers and third-party suppliers. Such companies may also be dependent upon suppliers for the products used for their own brand name merchandise. Reliance on third party suppliers subjects retail companies to risks of delivery delays, price increases and receipt of nonconforming or poor quality merchandise. Retail companies may be unable to protect their intellectual property rights and may be liable for infringing the intellectual property rights of others. Changes in labor laws and other labor issues, such as increased labor costs, could adversely affect the financial performance of retail companies. If retail companies do not maintain the security of customer-related information, they could damage their reputations with customers, incur substantial costs and become subject to litigation, all of which could adversely affect the financial performance of such companies. The international operations of certain retail companies expose them to risks associated with instability and changes in economic and political conditions, foreign currency fluctuations, changes in foreign regulations, tariffs and trade disputes and other risks inherent to international business. Some of the companies in the Retail Index are engaged in other lines of business unrelated to retail, and they may experience problems with these lines of business which could adversely affect their operating results. The operating results of these companies may fluctuate as a result of these additional risks and events in the other lines of business. In addition, a company’s ability to engage in new activities may expose it to business risks with which it has less experience than it has with the business risks associated with its traditional businesses. Despite a company’s possible success in traditional retail activities, the other lines of business in which these companies are engaged may have an adverse effect on a company’s business or financial condition.

 

UNITED STATES RISK. Certain changes in the U.S. economy, such as when the U.S. economy weakens or when its financial markets decline, may have an adverse effect on the securities to which the Fund has exposure.

NON-DIVERSIFICATION RISK. As a “non-diversified” fund, the Fund may hold a smaller number of portfolio securities than many other funds. To the extent the Fund invests in a relatively small number of issuers, a decline in the market value of a particular security held by the Fund may affect its value more than if it invested in a larger number of issuers. The value of the Fund Shares may be more volatile than the values of shares of more diversified funds.

Roundhill COIN WeeklyPay™ ETF | MARKET RISK  
Prospectus [Line Items]  
Risk [Text Block]

MARKET RISK. Market risk is the risk that a particular investment, or Fund Shares in general, may fall in value. Securities are subject to market fluctuations caused by real or perceived adverse economic, political, and regulatory factors or market developments, changes in interest rates, disruptions to trade, impositions of tariffs and perceived trends in securities prices. Fund Shares could decline in value or underperform other investments. In addition, local, regional or global events such as war, acts of terrorism, market manipulation, government defaults, government shutdowns, regulatory actions, political changes, diplomatic developments, the imposition of sanctions and other similar measures, spread of infectious diseases or other public health issues, recessions, natural disasters, or other events could have a significant negative impact on the Fund and its investments. Any of such circumstances could have a materially negative impact on the value of Fund Shares, the liquidity of an investment, and may result in increased market volatility. During any such events, Fund Shares may trade at increased premiums or discounts to their net asset value, the bid/ask spread on Fund Shares may widen and the returns on investment may fluctuate.

Roundhill COIN WeeklyPay™ ETF | LIQUIDITY RISK  
Prospectus [Line Items]  
Risk [Text Block]

LIQUIDITY RISK. The market for swap agreements that reference COIN shares may be subject to periods of illiquidity. During such times it may be difficult or impossible to buy or sell a position at the desired price. Market disruptions or volatility can also make it difficult to find a counterparty willing to transact at a reasonable price and sufficient size. Illiquid markets may cause losses, which could be significant. The large size of the positions which the Fund may acquire increases the risk of illiquidity, may make its positions more difficult to liquidate, and may increase the losses incurred while trying to do so. Such large positions also may impact the price of swap agreements on COIN shares.

Roundhill COIN WeeklyPay™ ETF | ACTIVE MANAGEMENT RISK  
Prospectus [Line Items]  
Risk [Text Block]

ACTIVE MANAGEMENT RISK. The Fund is actively-managed and its performance reflects investment decisions that the Adviser and/or Sub-Adviser makes for the Fund. Such judgments about the Fund’s investments may prove to be incorrect. If the investments selected and the strategies employed by the Fund fail to produce the intended results, the Fund could underperform as compared to other funds with similar investment objectives and/or strategies, or could have negative returns.

Roundhill COIN WeeklyPay™ ETF | ACTIVE MARKET RISK  
Prospectus [Line Items]  
Risk [Text Block]

ACTIVE MARKET RISK. Although Fund Shares are listed for trading on the Exchange, there can be no assurance that an active trading market for Fund Shares will develop or be maintained. Fund Shares trade on the Exchange at market prices that may be below, at or above the Fund’s net asset value. Securities, including Fund Shares, are subject to market fluctuations and liquidity constraints that may be caused by such factors as economic, political, or regulatory developments, changes in interest rates, and/or perceived trends in securities prices. Fund Shares could decline in value or underperform other investments.

Roundhill COIN WeeklyPay™ ETF | ASSET CLASS RISK

Risk [Text Block]

CONCENTRATION RISK. The Fund is susceptible to an increased risk of loss, including losses due to adverse events that affect the Fund’s investments more than the market as a whole, to the extent that the Fund’s investments are concentrated in investments that provide exposure to COIN and the industry to which it is assigned.

Roundhill COIN WeeklyPay™ ETF | COUNTERPARTY RISK  
Prospectus [Line Items]  
Risk [Text Block]

COUNTERPARTY RISK. Fund transactions involving a counterparty are subject to the risk that the counterparty will not fulfill its obligation to the Fund. Counterparty risk may arise because of the counterparty’s financial condition (i.e., financial difficulties, bankruptcy, or insolvency), market activities and developments, or other reasons, whether foreseen or not. A counterparty’s inability to fulfill its obligation may result in significant financial loss to the Fund. The Fund may be unable to recover its investment from the counterparty or may obtain a limited recovery, and/or recovery may be delayed.

Risk [Text Block]

CREDIT RISK. An issuer or other obligated party of a debt security may be unable or unwilling to make dividend, interest and/or principal payments when due. In addition, the value of a debt security may decline because of concerns about the issuer’s ability or unwillingness to make such payments.

Roundhill COIN WeeklyPay™ ETF | CYBERSECURITY RISK  
Prospectus [Line Items]  
Risk [Text Block]

CYBERSECURITY RISK. Failures or breaches of the electronic systems of the Fund, the Fund’s adviser, sub-adviser, distributor and other service providers, market makers, Authorized Participants or the issuers of securities in which the Fund invests have the ability to cause disruptions, negatively impact the Fund’s business operations and/or potentially result in financial losses to the Fund and its shareholders. While the Fund has established business continuity plans and risk management systems seeking to address system breaches or failures, there are inherent limitations in such plans and systems. Furthermore, the Fund cannot control the cybersecurity plans and systems of the Fund’s other service providers, market makers, Authorized Participants or issuers of securities in which the Fund invests.

Roundhill COIN WeeklyPay™ ETF | DEBT SECURITIES RISK  
Prospectus [Line Items]  
Risk [Text Block]

DEBT SECURITIES RISK. Investments in debt securities subject the holder to the credit risk of the issuer. Credit risk refers to the possibility that the issuer or other obligor of a security will not be able or willing to make payments of interest and principal when due. Generally, the value of debt securities will change inversely with changes in interest rates. To the extent that interest rates rise, certain underlying obligations may be paid off substantially slower than originally anticipated and the value of those securities may fall sharply. During periods of falling interest rates, the income received by the Fund may decline. If the principal on a debt security is prepaid before expected, the prepayments of principal may have to be reinvested in obligations paying interest at lower rates. Debt securities generally do not trade on a securities exchange making them generally less liquid and more difficult to value than common stock.

Roundhill COIN WeeklyPay™ ETF | DERIVATIVES RISK  
Prospectus [Line Items]  
Risk [Text Block]

DERIVATIVES RISK. The use of derivative instruments involves risks different from, or possibly greater than, the risks associated with investing directly in securities and other traditional investments. These risks include: (i) the risk that the counterparty to a derivative transaction may not fulfill its contractual obligations; (ii) risk of mispricing or improper valuation; and (iii) the risk that changes in the value of the derivative may not correlate perfectly with the underlying asset. Derivative prices are highly volatile and may fluctuate substantially during a short period of time. Such prices are influenced by numerous factors that affect the markets, including, but not limited to: changing supply and demand relationships; government programs and policies; national and international political and economic events, changes in interest rates, inflation and deflation and changes in supply and demand relationships. Trading derivative instruments involves risks different from, or possibly greater than, the risks associated with investing directly in securities. Derivative contracts ordinarily have leverage inherent in their terms. The use of leverage may cause the Fund to liquidate portfolio positions when it would not be advantageous to do so in order to satisfy its obligations or to meet regulatory or contractual requirements for derivatives. The use of derivatives can magnify potential for gain or loss and, therefore, amplify the effects of market volatility on share price.

Roundhill COIN WeeklyPay™ ETF | DISTRIBUTION TAX RISK  
Prospectus [Line Items]  
Risk [Text Block]

DISTRIBUTION TAX RISK. The Fund currently expects to make distributions on a weekly basis. Such frequent distributions may expose investors to increased tax liabilities. However, these distributions may exceed the Fund’s income and gains for the Fund’s taxable year. Distributions in excess of the Fund’s current and accumulated earnings and profits will be treated as a return of capital. A return of capital distribution generally will not be taxable but will reduce the shareholder’s cost basis and will result in a higher capital gain or lower capital loss when those Fund Shares on which the distribution was received are sold. Once a Fund shareholder’s cost basis is reduced to zero, further distributions will be treated as capital gain if the Fund shareholder holds Fund Shares as capital assets. Additionally, any capital returned through distributions will be distributed after payment of Fund fees and expenses. Because a portion of the Fund’s distributions may consist of return of capital, the Fund may not be an appropriate investment for investors who do not want their principal investment in the Fund to decrease over time or who do not wish to receive return of capital in a given period. In the event that a shareholder purchases Fund Shares shortly before a distribution by the Fund, the entire distribution may be taxable to the shareholder even though a portion of the distribution effectively represents a return of the purchase price.

Roundhill COIN WeeklyPay™ ETF | ETF RISK  
Prospectus [Line Items]  
Risk [Text Block]

ETF RISK. The Fund may invest in ETFs. The value of an ETF held by the Fund will fluctuate over time based on fluctuations in the values of the assets held by the ETF, which may be affected by changes in general economic conditions, expectations for future growth and profits, interest rates and the supply and demand for those assets. When the Fund invests in an ETF, it will bear a proportionate share of the ETF’s expenses. Brokerage, tax and other expenses may negatively impact the performance of the ETF and, in turn, the value of the Fund Shares. An ETF that tracks an index may not exactly match the performance of the index due to cash drag, differences between the portfolio of the ETF and the components of the index, expenses and other factors.

Roundhill COIN WeeklyPay™ ETF | INFLATION RISK  
Prospectus [Line Items]  
Risk [Text Block]

INFLATION RISK. Inflation risk is the risk that the value of assets or income from investments will be less in the future as inflation decreases the value of money. As inflation increases, the present value of the Fund’s assets and distributions may decline. This risk is more prevalent with respect to fixed income securities held by the Fund.

Roundhill COIN WeeklyPay™ ETF | Interest Rate Risk [Member]  
Prospectus [Line Items]  
Risk [Text Block]

INTEREST RATE RISK. Interest rate risk is the risk that the value of the debt securities in the Fund’s portfolio will decline because of rising market interest rates. Interest rate risk is generally lower for shorter term debt securities and higher for longer-term debt securities. Duration is a reasonably accurate measure of a debt security’s price sensitivity to changes in interest rates and a common measure of interest rate risk. Duration measures a debt security’s expected life on a present value basis, taking into account the debt security’s yield, interest payments and final maturity. In general, duration represents the expected percentage change in the value of a security for an immediate 1% change in interest rates. For example, the price of a debt security with a three-year duration would be expected to drop by approximately 3% in response to a 1% increase in interest rates. Therefore, prices of debt securities with shorter durations tend to be less sensitive to interest rate changes than debt securities with longer durations. As the value of a debt security changes over time, so will its duration.

Roundhill COIN WeeklyPay™ ETF | LEGISLATION AND LITIGATION RISK  
Prospectus [Line Items]  
Risk [Text Block]

LEGISLATION AND LITIGATION RISK. Legislation or litigation that affects the value of assets or securities held by the Fund may reduce the value of the Fund. From time to time, various legislative initiatives are proposed that may have a negative impact on certain assets or securities in which the Fund invests. In addition, litigation regarding any of the assets or securities owned by the Fund may negatively impact the value of the Shares. Such legislation or litigation may cause the Fund to lose value or may result in higher portfolio turnover if the Adviser determines to sell such a holding.

Roundhill COIN WeeklyPay™ ETF | LEVERAGE RISK  
Prospectus [Line Items]  
Risk [Text Block]

LEVERAGE RISK. The Fund obtains investment exposure in excess of its net assets by utilizing leverage and may lose more money in market conditions that are adverse to its investment objectives than a fund that does not utilize leverage. An investment in the Fund is exposed to the risk that a decline in the weekly performance of shares of COIN will be magnified. This means that an investment in the Fund will be reduced by an amount equal to 1.2% for every 1% weekly decline in the market value of the COIN shares, not including the costs of financing leverage and other operating expenses, which would further reduce its value. The Fund could theoretically lose an amount greater than its net assets in the event the market value of COIN shares decline more than 83.33% over a calendar week. Leverage will also have the effect of magnifying any differences in the Fund’s correlation with COIN shares.

Roundhill COIN WeeklyPay™ ETF | MONEY MARKET INSTRUMENTS RISK  
Prospectus [Line Items]  
Risk [Text Block]

MONEY MARKET INSTRUMENTS RISK. The value of money market instruments may be affected by changing interest rates and by changes in the credit ratings of the investments. If a significant amount of the Fund’s assets are invested in money market instruments, it will be more difficult for the Fund to achieve its investment objectives. An investment in a money market fund is not insured or guaranteed by the FDIC or any other government agency. It is possible to lose money by investing in a money market fund.

Roundhill COIN WeeklyPay™ ETF | OPERATIONAL RISK  
Prospectus [Line Items]  
Risk [Text Block]

OPERATIONAL RISK. The Fund is subject to risks arising from various operational factors, including, but not limited to, human error, processing and communication errors, errors of the Fund’s service providers, counterparties or other third-parties, failed or inadequate processes and technology or systems failures. The Fund relies on third-parties for a range of services, including custody. Any delay or failure relating to engaging or maintaining such service providers may affect the Fund’s ability to meet its investment objectives. Although the Fund and the Adviser seek to reduce these operational risks through controls and procedures, there is no way to completely protect against such risks.

Roundhill COIN WeeklyPay™ ETF | SPECIAL TAX RISK  
Prospectus [Line Items]  
Risk [Text Block]

SPECIAL TAX RISK. The Fund intends to qualify annually and to elect to be treated as a regulated investment company under the Internal Revenue Code of 1986, as amended (the “Code”). To qualify for the favorable U.S. federal income tax treatment generally accorded to regulated investment companies, the Fund must, among other things, (i) derive in each taxable year at least 90% of its gross income from dividends, interest, payments with respect to securities loans and gains from the sale or other disposition of stock, securities or foreign currencies or other income derived with respect to its business of investing in such stock, securities or currencies, or net income derived from interests in certain publicly traded partnerships; (ii) diversify its holdings so that, at the end of each quarter of the taxable year, (a) at least 50% of the market value of the Fund’s assets is represented by cash and cash items (including receivables), U.S. government securities, the securities of other regulated investment companies and other securities, with such other securities of any one issuer generally limited for the purposes of this calculation to an amount not greater than 5% of the value of the Fund’s total assets and not greater than 10% of the outstanding voting securities of such issuer, and (b) not more than 25% of the value of its total assets is invested in the securities (other than U.S. government securities or the securities of other regulated investment companies) of any one issuer, or two or more issuers which the Fund controls which are engaged in the same, similar or related trades or businesses, or the securities of one or more of certain publicly traded partnerships; and (iii) distribute at least 90% of its investment company taxable income (which includes, among other items, dividends, interest and net short-term capital gains in excess of net long-term capital losses) and at least 90% of its net tax-exempt interest income each taxable year. There are certain exceptions for failure to qualify if the failure is for reasonable cause or is de minimis, and certain corrective action is taken and certain tax payments are made by the Fund.

 

The authority with regard to swaps entered into by regulated investment companies is unclear both as to the qualification under the income test and the identification of the issuer under the diversification test. The Fund intends to take the position that because the swaps held by the Fund reference securities that the income on the swaps are “other income” from the Fund’s business of investing in stocks and securities. In addition, the Fund intends to manage its investments in the swaps so that neither the exposure to issuer of the referenced security nor the exposure to any one counterparty of the swaps will exceed 25% of the gross value of the Fund’s portfolio at the end of any quarter.

 

If the Fund were to fail to meet the qualifying income test or asset diversification test and fail to qualify as a RIC, it would be taxed in the same manner as an ordinary corporation, and distributions to its shareholders would not be deductible by the Fund in computing its taxable income, which would adversely affect the Fund’s performance.

Roundhill COIN WeeklyPay™ ETF | STRUCTURAL ETF RISKS  
Prospectus [Line Items]  
Risk [Text Block]

STRUCTURAL ETF RISKS. The Fund is an ETF. Accordingly, it is subject to certain risks associated with its unique structure.

 

Market Participants Risk. Only an Authorized Participant may engage in creation or redemption transactions directly with the Fund, and none of those Authorized Participants is obligated to engage in creation and/or redemption transactions. The Fund has a limited number of institutions that may act as Authorized Participants on an agency basis (i.e., on behalf of other market participants). To the extent that Authorized Participants exit the business or are unable to proceed with creation or redemption orders with respect to the Fund and no other Authorized Participant is able to step forward to create or redeem, Fund Shares may be more likely to trade at a premium or discount to NAV and possibly face trading halts or delisting. The Fund may also rely on a small number of third-party market makers to provide a market for the purchase and sale of Fund Shares but such market makers are under no obligation to do so. Decisions by Authorized Participants or market makers to reduce their role or step away from these activities in times of market stress could inhibit the effectiveness of the arbitrage process in maintaining the relationship between the underlying values of the Fund’s portfolio securities and the Fund’s market price. Any trading halt or other problem relating to the trading activity of these market makers or any issues disrupting the Authorized Participants’ ability to proceed with creation and/or redemption orders could result in a dramatic change in the spread between the Fund’s net asset value and the price at which Fund Shares are trading on the Exchange, which could result in a decrease in value of Fund Shares. This reduced effectiveness could result in Fund Shares trading at a premium or discount to net asset value and also in greater than normal intraday bid-ask spreads Fund Shares.

 

Cash Transactions Risk. The Fund currently expects to effect a significant portion of its creations and redemptions for cash, rather than in-kind securities. Paying redemption proceeds in cash rather than through in-kind delivery of portfolio securities may require the Fund to dispose of or sell portfolio securities or other assets at an inopportune time to obtain the cash needed to meet redemption orders. This may cause the Fund to sell a security and recognize a capital gain or loss that might not have been incurred if it had made a redemption in-kind. As a result, the Fund may pay out higher or lower annual capital gains distributions than ETFs that redeem in-kind. The use of cash creations and redemptions may also cause the Fund’s Shares to trade in the market at greater bid-ask spreads or greater premiums or discounts to the Fund’s net asset value (“NAV”). Furthermore, the Fund may not be able to execute cash transactions for creation and redemption purposes at the same price used to determine the Fund’s NAV. To the extent that the maximum additional charge for creation or redemption transactions is insufficient to cover the execution shortfall, the Fund’s performance could be negatively impacted.

 

Costs of Buying and Selling Fund Shares. Due to the costs of buying or selling Fund Shares, including brokerage commissions imposed by brokers and bid/ask spreads, frequent trading of Fund Shares may significantly reduce investment results and an investment in Fund Shares may not be advisable for investors who anticipate regularly making small investments.

 

Premium/Discount Risk. As with all ETFs, Fund Shares may be bought and sold in the secondary market at market prices. The trading prices of Fund Shares in the secondary market may differ from the Fund’s daily NAV per Fund Share and there may be times when the market price of the Fund Shares is more than the NAV per Fund Share (premium) or less than the NAV per Fund Share (discount). If a shareholder purchases Fund Shares at a time when the market price is at a premium to the NAV or sells Fund Shares at a time when the market price is at a discount to the NAV, the shareholder may pay more for, or receive less than, the underlying value of the Fund Shares, respectively. This risk is heightened in times of market volatility or periods of steep market declines.

 

Trading Risks. Although Fund Shares are listed for trading on the Exchange and may be traded on U.S. exchanges other than the Exchange, there can be no assurance that Fund Shares will trade with any volume, or at all, on any stock exchange. In stressed market conditions, the liquidity of Fund Shares may begin to mirror the liquidity of the Fund’s underlying portfolio holdings, which can be significantly less liquid than Fund Shares. Trading in Fund Shares on the Exchange may be halted due to market conditions or for reasons that, in the view of the Exchange, make trading in Fund Shares inadvisable. In addition, trading in Fund Shares on the Exchange is subject to trading halts caused by extraordinary market volatility pursuant to the Exchange’s “circuit breaker” rules. There can be no assurance that the requirements of the Exchange necessary to maintain the listing of the Fund will continue to be met or will remain unchanged.

Risk [Text Block]

U.S. GOVERNMENT SECURITIES RISK. U.S. government securities are subject to interest rate risk but generally do not involve the credit risks associated with investments in other types of debt securities. As a result, the yields available from U.S. government securities are generally lower than the yields available from other debt securities. U.S. government securities are guaranteed only as to the timely payment of interest and the payment of principal when held to maturity.

Roundhill COIN WeeklyPay™ ETF | VALUATION RISK  
Prospectus [Line Items]  
Risk [Text Block]

VALUATION RISK. The Fund may hold securities or other assets that may be valued on the basis of factors other than market quotations. This may occur because the asset or security does not trade on a centralized exchange, or in times of market turmoil or reduced liquidity. There are multiple methods that can be used to value a portfolio holding when market quotations are not readily available. The value established for any portfolio holding at a point in time might differ from what would be produced using a different methodology or if it had been priced using market quotations. Portfolio holdings that are valued using techniques other than market quotations, including “fair valued” assets or securities, may be subject to greater fluctuation in their valuations from one day to the next than if market quotations were used. In addition, there is no assurance that the Fund could sell or close out a portfolio position for the value established for it at any time, and it is possible that the Fund would incur a loss because a portfolio position is sold or closed out at a discount to the valuation established by the Fund at that time. The Fund’s ability to value investments may be impacted by technological issues or errors by pricing services or other third-party service providers.

Roundhill COIN WeeklyPay™ ETF | EQUITY SECURITIES RISK

Risk [Text Block]

EQUITY SECURITIES RISK. Equity securities are subject to changes in value, and their values may be more volatile than those of other asset classes. Equity securities prices fluctuate for several reasons, including changes in investors’ perceptions of the financial condition of an issuer or the general condition of the relevant equity market, such as market volatility, or when political or economic events affecting an issuer occur. Common stock prices may be particularly sensitive to rising interest rates, as the cost of capital rises and borrowing costs increase. Common stocks generally subject their holders to more risks than preferred stocks and debt securities because common stockholders’ claims are subordinated to those of holders of preferred stocks and debt securities upon the bankruptcy of the issuer.

Roundhill COIN WeeklyPay™ ETF | SWAP AGREEMENTS RISK  
Prospectus [Line Items]  
Risk [Text Block]

SWAP AGREEMENTS RISK. The Fund will utilize swap agreements to derive its exposure to shares of COIN. Swap agreements may involve greater risks than direct investment in securities as they may be leveraged and are subject to credit risk, counterparty risk and valuation risk. A swap agreement could result in losses if the underlying reference or asset does not perform as anticipated. In addition, many swaps trade over-the-counter and may be considered illiquid. It may not be possible for the Fund to liquidate a swap position at an advantageous time or price, which may result in significant losses.

Roundhill COIN WeeklyPay™ ETF | REGULATED INVESTMENT COMPANY TAX RISKS  
Prospectus [Line Items]  
Risk [Text Block]

REGULATED INVESTMENT COMPANY TAX RISKS. The Fund intends to qualify annually and to elect to be treated as a regulated investment company under the Internal Revenue Code of 1986, as amended (the “Code”). To qualify for the favorable U.S. federal income tax treatment generally accorded to regulated investment companies, the Fund must, among other things, (i) derive in each taxable year at least 90% of its gross income from dividends, interest, payments with respect to securities loans and gains from the sale or other disposition of stock, securities or foreign currencies or other income derived with respect to its business of investing in such stock, securities or currencies, or net income derived from interests in certain publicly traded partnerships; (ii) diversify its holdings so that, at the end of each quarter of the taxable year, (a) at least 50% of the market value of the Fund’s assets is represented by cash and cash items (including receivables), U.S. government securities, the securities of other regulated investment companies and other securities, with such other securities of any one issuer generally limited for the purposes of this calculation to an amount not greater than 5% of the value of the Fund’s total assets and not greater than 10% of the outstanding voting securities of such issuer, and (b) not more than 25% of the value of its total assets is invested in the securities (other than U.S. government securities or the securities of other regulated investment companies) of any one issuer, or two or more issuers which the Fund controls which are engaged in the same, similar or related trades or businesses, or the securities of one or more of certain publicly traded partnerships; and (iii) distribute at least 90% of its investment company taxable income (which includes, among other items, dividends, interest and net short-term capital gains in excess of net long-term capital losses) and at least 90% of its net tax-exempt interest income each taxable year. There are certain exceptions for failure to qualify if the failure is for reasonable cause or is de minimis, and certain corrective action is taken and certain tax payments are made by the Fund.

 

If the Fund were to fail to meet the qualifying income test or asset diversification test and fail to qualify as a RIC, it would be taxed in the same manner as an ordinary corporation, and distributions to its shareholders would not be deductible by the Fund in computing its taxable income, which would adversely affect the Fund’s performance.

Roundhill COIN WeeklyPay™ ETF | LARGE SHAREHOLDER RISK  
Prospectus [Line Items]  
Risk [Text Block]

LARGE SHAREHOLDER RISK. Certain shareholders, including affiliated funds advised by the Adviser, may from time to time own a significant portion of the Fund’s shares. In addition, a third-party investor, the Adviser or an affiliate of the Adviser (“Affiliate”), an authorized participant, a market maker, or another entity may invest in the Fund and hold its investment for a limited period solely to facilitate the commencement of the Fund or to help the Fund achieve a specified size or scale. There can be no assurance that any large shareholder will not redeem its investment, that the size of the Fund will be maintained at such levels, or that the Fund will continue to meet applicable listing requirements. Redemptions by large shareholders could have a significant negative impact on the Fund. In addition, transactions by large shareholders may account for a large percentage of the trading volume on the Fund’s listing exchange and may, therefore, have a material upward or downward effect on the market price of the shares.

 

To the extent that a significant percentage of the Fund’s shares are owned or controlled by a small number of account shareholders (or a single account shareholder), including funds or accounts over which the Adviser or an Affiliate has investment discretion, the Fund is subject to the risk that those shareholders may purchase or redeem Fund shares in significant amounts rapidly or unexpectedly, including as a result of an asset allocation decision made by the Adviser or an Affiliate. This may adversely affect the Fund’s performance if the Adviser is forced to sell portfolio securities or invest cash when it would not otherwise choose to do so. Redemptions of a large number of shares may affect the liquidity of the Fund’s portfolio, increase the Fund’s transaction costs, and accelerate the realization of taxable income and/or gains. In addition, a large redemption could result in the Fund’s current expenses being allocated over a smaller asset base, leading to an increase in the Fund’s gross expense ratio. Large purchases of the Fund’s shares may also adversely affect the Fund’s performance to the extent that the Fund is delayed in investing new cash or otherwise maintains a larger cash position than it ordinarily would, particularly if the Fund accepts cash for an order for the purchase of creation units of the Fund’s shares.

Roundhill COIN WeeklyPay™ ETF | COIN INVESTING RISKS  
Prospectus [Line Items]  
Risk [Text Block]

COIN INVESTING RISKS. The Fund will have significant exposure to COIN through its investments in swap agreements that utilize COIN as the reference asset. Accordingly, the Fund will subject to the risks of COIN, set forth below.

 

COIN ISSUER-SPECIFIC RISKS. Issuer-specific attributes may cause an investment held by the Fund to be more volatile than the market generally. The value of an individual security or particular type of security may be more volatile than the market as a whole and may perform differently from the value of the market as a whole. As of the date of this prospectus, COIN faces risks associated with companies in the financials sector, as well as those relating to the “crypto industry ecosystem.” The technology relating to the crypto industry ecosystem is new and developing and the risks associated with crypto assets may not fully emerge until the technology is widely used. Technologies utilizing cryptography are used by companies to optimize their business practices, whether by using the technology within their business or operating business lines involved in the operation of the technology. Cryptography refers to a set of techniques designed to allow for secure communication in the presence of adversarial behavior. Blockchain is a well-known example of a technology that relies on cryptography. A blockchain is comprised of unchangeable, digitally recorded data in packages called “blocks.” These digitally recorded blocks of data are stored in a linear “chain.” Each block in the chain contains data (e.g., a transaction), that is cryptographically connected to the previous-block in the chain, ensuring all data in the overall “blockchain” has not been tampered with and remains unchanged. The cryptographic keys necessary to transact a crypto asset may be subject to theft, loss, or destruction, which could adversely affect a company’s business or operations if it were dependent on such an asset. Competing platforms and technologies may be developed such that consumers or investors use an alternative to crypto assets. There may be risks posed by the lack of regulation for crypto assets and any future regulatory developments could affect the viability and expansion of the use of crypto technologies. Recently, U.S. securities regulators have brought actions against companies operating in the crypto industry ecosystem for violations of U.S. securities laws. To the extent such an action is brought against a company held by the Fund, the value of such a holding could decrease significantly. Because companies operating in the crypto industry ecosystem may operate across many national boundaries and regulatory jurisdictions, it is possible that such companies may be subject to widespread and inconsistent regulation. Companies operating in the crypto industry ecosystem that rely on third party products may be subject to technical defects or vulnerabilities beyond a company’s control. Because many crypto assets do not have a standardized exchange, like a stock market, there is less liquidity for such assets and greater possibility of volatility, fraud or manipulation. In addition, these companies may engage in other lines of business unrelated to the crypto industry ecosystem and these lines of business could adversely affect their operating results. Such companies may be engaged in activities traditionally comprising the information technology sector and financial sectors. These companies also may not be able to develop crypto technology applications or may not be able to capitalize on those applications. Technologies also may never be fully implemented, which could adversely affect an investment in such companies. Companies that use crypto technologies may be subject to cybersecurity risk. In addition, certain features of crypto industry technologies, such as decentralization, open source protocol, and reliance on peer-to-peer connectivity, may increase the risk of fraud or cyber-attack by potentially reducing the likelihood of a coordinated response. A significant disruption of internet connectivity affecting large numbers of users or geographic areas could impede the functionality of crypto technologies. Companies that use crypto technologies may be subject to the risks posed by conflicting intellectual property claims, which may reduce confidence in the viability of a crypto asset.

 

INDIRECT INVESTMENT RISK. Coinbase Global, Inc. is not affiliated with the Trust, the Fund, the Adviser, the Sub-Adviser or any affiliates thereof and is not involved with this offering in any way, and has no obligation to consider the Fund in taking any corporate actions that might affect the value of the Fund. The Trust, the Fund, the Adviser, the Sub-Adviser or any affiliate are not responsible for the performance of COIN and make no representation as to the performance of COIN. Investing in the Fund is not equivalent to investing in COIN. Fund shareholders will not have voting rights or rights to receive dividends or other distributions or any other rights with respect to COIN.

 

FINANCIALS COMPANIES RISK. Companies in the financials sector are subject to extensive governmental regulation and intervention, which may adversely affect the scope of their activities, the prices they can charge, the amount of capital and liquid assets they must maintain and, potentially, their size. Governmental regulation may change frequently and may have significant adverse consequences for companies in the financials sector, including effects not intended by such regulation. Increased risk taking by financial companies may also result in greater overall risk in the U.S. and global financials sector. The impact of changes in capital requirements, or recent or future regulation in various countries, on any individual financial company or on the financials sector as a whole cannot be predicted.

 

Certain risks may impact the value of investments in the financials sector more severely than those of investments outside this sector, including the risks associated with companies that operate with substantial financial leverage. Companies in the financials sector are exposed directly to the credit risk of their borrowers and counterparties, who may be leveraged to an unknown degree, including through swaps and other derivatives products. Financial services companies may have significant exposure to the same borrowers and counterparties, with the result that a borrower’s or counterparty’s inability to meet its obligations to one company may affect other companies with exposure to the same borrower or counterparty. This interconnectedness of risk may result in significant negative impacts to companies with direct exposure to the defaulting counterparty as well as adverse cascading effects in the markets and the financials sector generally. Companies in the financials sector may also be adversely affected by increases in interest rates and loan losses, decreases in the availability of money or asset valuations, credit rating downgrades, adverse public perception and adverse conditions in other related markets. Insurance companies, in particular, may be subject to severe price competition and/or rate regulation, which may have an adverse impact on their profitability. The financials sector is particularly sensitive to fluctuations in interest rates. The financials sector is also a target for cyberattacks. Cybersecurity incidents and technology malfunctions and failures have become increasingly frequent and have caused significant losses to companies in this sector, which may negatively impact the Fund. The extent to which the Fund may invest in a company that engages in securities-related activities or banking is limited by applicable law.

 

LARGE CAPITALIZATION COMPANIES RISK. Large capitalization companies may be less able than smaller capitalization companies to adapt to changing market conditions. Large capitalization companies may be more mature and subject to more limited growth potential compared with smaller capitalization companies. During different market cycles, the performance of large capitalization companies has trailed the overall performance of the broader securities markets.

 

UNITED STATES RISK. Certain changes in the U.S. economy, such as when the U.S. economy weakens or when its financial markets decline, may have an adverse effect on the securities to which the Fund has exposure.

Roundhill COIN WeeklyPay™ ETF | DIGITAL ASSETS RISK  
Prospectus [Line Items]  
Risk [Text Block]

DIGITAL ASSETS RISK. COIN’s business model is heavily dependent on digital assets, the blockchain technology upon which such digital assets rely and the digital asset industry. Accordingly, it is subject the risks associated with digital assets, as set forth below.

 

BITCOIN RISK. Bitcoin is a relatively new innovation and the market for bitcoin is subject to rapid price swings, changes and uncertainty. The further development of the Bitcoin network and the acceptance and use of bitcoin are subject to a variety of factors that are difficult to evaluate. The value of bitcoin has been, and may continue to be, substantially dependent on speculation, such that trading and investing in these assets generally may not be based on fundamental analysis. The slowing, stopping or reversing of the development of the Bitcoin network or the acceptance of bitcoin may adversely affect the price of bitcoin. Bitcoin is subject to the risk of fraud, theft, manipulation or security failures, operational or other problems that impact the digital asset trading venues on which bitcoin trades. The Bitcoin blockchain may contain flaws that can be exploited by hackers. A significant portion of bitcoin is held by a small number of holders sometimes referred to as “whales.” Transactions of these holders may influence the price of bitcoin.

 

Unlike the exchanges for more traditional assets, such as equity securities and futures contracts, bitcoin and the digital asset trading venues on which it trades are largely unregulated and highly fragmented and digital asset trading venues may be operating out of compliance with regulations. As a result of the lack of regulation, individuals or groups may engage in fraud or market manipulation (including using social media to promote bitcoin in a way that artificially increases the price of bitcoin). Investors may be more exposed to the risk of theft, fraud and market manipulation than when investing in more traditional asset classes. Over the past several years, a number of digital asset trading venues have been closed due to fraud, failure or security breaches. Investors in bitcoin may have little or no recourse should such theft, fraud or manipulation occur and could suffer significant losses. Legal or regulatory changes may negatively impact the operation of the Bitcoin network or restrict the use of bitcoin. COIN may also be negatively impacted by regulatory enforcement actions against the digital asset trading venues upon which bitcoin trades. Such actions could significantly reduce the number of venues upon which bitcoin trades and could negatively impact the price of bitcoin. In addition, digital asset trading venues, bitcoin miners, and other participants may have significant exposure to other digital assets. Instability in the price, availability or legal or regulatory status of those instruments may adversely impact the operation of the digital asset trading venues and the Bitcoin network. The realization of any of these risks could result in a decline in the acceptance of bitcoin and consequently a reduction in the value of bitcoin and shares of COIN.

 

The Bitcoin network is maintained and secured by a group of validators who “mine” bitcoin, which involves contributing computer power to the network to validate transactions, maintain security and finalize settlement. The Bitcoin blockchain relies on a consensus mechanism whereby miners agree on the accurate state of the database. If a malicious actor (or group of actors) were to gain control of more than 50% the mining (or “hash”) power in the network, even temporarily, they would have the ability to block new transactions from being confirmed and could, over time, reverse or reorder prior transactions. Although it may be challenging for a malicious actor (or group of actors) to gain control of 50% of the mining (or “hash”) power in the Bitcoin blockchain, such an attack would significantly impact the value of bitcoin.

 

A blockchain is a public database that is updated, shared and maintained across many computers in a network. The software that powers a blockchain is known as its protocol. Like all software, these protocols may update or change from time-to-time. In the case of the Bitcoin protocol, updates are made based on proposals submitted by developers, but only if a majority of the users and miners adopt the new proposals and update their individual copies of the protocol. Certain upgrade proposals to a blockchain may not be accepted by all the participants in an ecosystem. If one significant group adopts a proposed upgrade and another does not – or if groups adopt different upgrades – this can result in a “fork” of the blockchain, wherein two distinct sets of users and validators or users and miners run two different versions of a protocol. If the versions are sufficiently different such that the two versions of the protocol cannot simultaneously maintain and update a shared record of the blockchain database, it is called a “hard fork.” A hard fork can result in the creation of two competing blockchains, each with its own native crypto assets. For instance, on August 1, 2017, two factions in the Bitcoin community could not agree on whether or not to adopt an upgrade to the Bitcoin protocol related to how to scale throughput on the blockchain. The disagreement created a fork, with the smaller group taking the name “Bitcoin Cash” and running its own blockchain and related native crypto asset. The larger group retained the name Bitcoin for its blockchain and held bitcoin as the native crypto asset. Additional forks of the Bitcoin blockchain are possible. A large-scale fork could introduce risk, uncertainty, or confusion into the Bitcoin blockchain, or could fraction the value of the main blockchain and its native crypto asset, which could significantly impact the value of bitcoin and shares of COIN. Additionally, a hack of the Bitcoin blockchain or one or more projects that interact with or that are built on top of the Bitcoin blockchain could negatively impact the price of bitcoin, whether it leads to another hard fork or not, and thereby the value of COIN.

 

The Bitcoin blockchain and its native crypto asset, bitcoin, face numerous challenges to gaining widespread adoption as an alternative payments system, including the slowness of transaction processing and finality, variability in transaction fees and volatility in bitcoin’s price. It is not clear that the Bitcoin blockchain or bitcoin can overcome these and other impediments, which could harm the long-term adoption of the Bitcoin blockchain and bitcoin as an alternative payment system, and thereby negatively impact the price of bitcoin. In addition, alternative public blockchains have been developed and may in the future develop that compete with the Bitcoin blockchain and may have significant advantages as alternative payment systems, including higher throughput, lower fees, faster settlement and finalization, and the ability to facilitate untraceable and/or privacy-shielded transactions through the use of zero-knowledge cryptography or other means. It is possible that these alternative public blockchains and their native crypto assets may be more successful than the Bitcoin blockchain and bitcoin in gaining adoption as an alternative payments system, which could limit the long-term adoption of the Bitcoin blockchain and bitcoin, thereby negatively impact the price of bitcoin. Such alternative public blockchains, such as the Ethereum network, allow users to write and implement smart contracts—that is, general-purpose code that executes on every computer in the network and can instruct the transmission of information and value based on a sophisticated set of logical conditions. Using smart contracts, users can create markets, store registries of debts or promises, represent the ownership of property, move funds in accordance with conditional instructions and create other digital assets. Furthermore, traditional payment systems may improve their own technical capabilities and offer faster settlement times, faster finalization and lower fees. This could make it more difficult for the Bitcoin blockchain and bitcoin to gain traction as an alternative payments system, which could limit the long-term adoption of the Bitcoin blockchain and bitcoin, and thereby negatively impact the price of bitcoin. Finally, one means by which the ecosystem surrounding the Bitcoin blockchain has attempted to mitigate concerns about the slowness of transaction processing and finality and the variability of transaction fees has been through the development of so-called Layer 2 networks, including the “Lightning Network.” Layer 2 networks are separate blockchains built on top of “Layer 1” blockchains like the Bitcoin blockchain for the purpose of augmenting the throughput of the Layer 1 blockchain, and often, providing lower fees for transaction processing and faster settlement. Layer 2 blockchains introduce certain risks into the Bitcoin ecosystem that should be considered. For instance, Layer 2 blockchains are a relatively new and still developing technology. Technological issues – including hacks, bugs, or failures – could introduce risk or harm confidence in the Bitcoin ecosystem, which could negatively impact the price of bitcoin. In addition, users may choose to settle an increasing share of transactions on Layer 2 blockchains, which could negatively impact the transaction activity on, and the amount of fee revenue generated by, the Bitcoin blockchain itself, which could negatively impact the price of bitcoin. If these or other developments negatively impact the price of bitcoin, this would negatively impact the value of the bitcoin.

 

BLOCKCHAIN TECHNOLOGY RISK. Blockchain technology is a relatively new and untested technology that operates as a distributed ledger. There are risks associated with a company’s issuance, redemption, transfer, and recordkeeping of shares on a blockchain, and these risks may not fully emerge until the technology becomes more widely used. Blockchain systems are public and permissionless, and could be vulnerable to fraud, particularly if a significant minority of participants collude to defraud the rest. Access to a given blockchain requires a private key, which, if compromised, could result in loss due to theft, destruction, or inaccessibility. There is limited regulation of blockchain technology other than the intrinsic public nature of the blockchain system, and any future regulatory developments could adversely affect the viability and expansion of the use of blockchain technology. There are currently a number of competing blockchain platforms with competing intellectual property claims, and the uncertainty inherent in these competing technologies could cause companies to use alternatives to blockchain. Blockchain networks may also undergo significant technological developments, such as the Ethereum blockchain’s change in September 2022 from proof-of-work mining to proof-of-stake validation. Blockchain networks can also experience delays in transaction processing and settlement, particularly during periods of high network congestion or increased transaction volume. Such delays could affect the timing of recording and processing transactions. During periods of congestion, the time required for transaction validation may increase, which could lead to delayed recording of transactions on the blockchain or off-chain recordkeeping systems. Furthermore, blockchain networks typically impose transaction fees in the form of the network’s native digital asset. These fees can be unpredictable and may vary significantly depending on network conditions and levels of congestion. Lastly, there may be undiscovered technical flaws in blockchain-integrated recordkeeping system or the underlying blockchain technology, including in the process by which transactions are recorded to a blockchain, recorded off-chain, and/or integrated with other recordkeeping systems. Such flaws could negatively impact the execution or recordkeeping of transactions. Additionally, technological advancements may lead to new or existing hardware or software tools or mechanisms that could undermine the integrity or functionality of blockchain systems. Blockchain software is generally open-source. Any user can download the software, modify it and then propose that network adopt the modification. When a modification is introduced and a substantial majority of users consent to the modification, the change is implemented and the blockchain network remains uninterrupted. However, if less than a substantial majority of users consent to the proposed modification, and the blockchain consensus mechanism allows for the modification to nonetheless be implemented by some users and the modification is not compatible with the software prior to its modification, the consequence would be what is known as a “fork” (i.e., “split”) of the blockchain network (and the blockchain), with one version running the pre-modified software and the other running the modified software. The effect of such a fork would be the existence of two (or more) versions of the blockchain network running in parallel, but with each version’s native asset lacking interchangeability. Additionally, a fork could be introduced by an unintentional, unanticipated software flaw in the multiple versions of otherwise compatible software users run. If a fork occurs, the original blockchain and the forked blockchain could potentially compete with each other for users and other participants, leading to a loss of these for the original blockchain.

 

CUSTODY RISK. Security breaches, computer malware and computer hacking attacks have been a prevalent concern in relation to digital assets. The bitcoin held by COIN will likely be an appealing target to hackers or malware distributors seeking to destroy, damage or steal the COIN’s bitcoins. To the extent that COIN is unable to identify and mitigate or stop new security threats or otherwise adapt to technological changes in the digital asset industry, COIN’s bitcoins may be subject to theft, loss, destruction or other attack.

 

COIN has put security procedures in place to prevent such theft, loss or destruction, including but not limited to, offline storage, or cold storage, multiple encrypted private key “shards”, and other measures. Nevertheless, the security procedures cannot guarantee the prevention of any loss due to a security breach, software defect or act of God that may be borne by COIN and the security procedures may not protect against all errors, software flaws or other vulnerabilities in COIN’s technical infrastructure, which could result in theft, loss or damage of its assets. Assets not held in cold storage, such as assets held in a trading account, may be more vulnerable to security breach, hacking or loss than assets held in cold storage. Furthermore, assets held in a trading account are held on an omnibus, rather than segregated basis, which creates greater risk of loss.

 

The security procedures and operational infrastructure may be breached due to the actions of outside parties, error or malfeasance of a COIN employee, and, as a result, an unauthorized party may obtain access to COIN’s accounts where its bitcoin is held, the relevant private keys (and therefore bitcoin) or other data or property of COIN. Additionally, outside parties may attempt to fraudulently induce employees of COIN to disclose sensitive information in order to gain access to COIN’s infrastructure. As the techniques used to obtain unauthorized access, disable or degrade service, or sabotage systems change frequently, or may be designed to remain dormant until a predetermined event and often are not recognized until launched against a target, COIN may be unable to anticipate these techniques or implement adequate preventative measures.

 

IRREVOCABILITY OF TRANSACTIONS RISK. Digital asset transactions are typically not reversible without the consent and active participation of the recipient of the transaction. Once a transaction has been verified and recorded in a block that is added to the blockchain, an incorrect transfer or theft of bitcoin generally will not be reversible and COIN may not be capable of seeking compensation for any such transfer or theft. It is possible that, through computer or human error, or through theft or criminal action, COIN’s bitcoin could be transferred from its account in incorrect amounts or to unauthorized third parties, or to uncontrolled accounts.

 

Such events have occurred in connection with digital assets in the past. For example, in September 2014, the Chinese digital asset platform Huobi announced that it had sent approximately 900 bitcoins and 8,000 Litecoins (worth approximately $400,000 at the prevailing market prices at the time) to the wrong customers. To the extent that COIN is unable to seek a corrective transaction with such third-party or is incapable of identifying the third-party which has received COIN’s bitcoins through error or theft, COIN will be unable to revert or otherwise recover incorrectly transferred bitcoins. COIN will also be unable to convert or recover its bitcoins transferred to uncontrolled accounts. To the extent that COIN is unable to seek redress for such error or theft, such loss could adversely affect the value of its shares.

 

DIGITAL ASSET TRADING PLATFORMS RISK. Digital asset platforms are relatively new and, in some cases, unregulated. Many operate outside the United States. Furthermore, while many prominent digital asset platforms provide the public with significant information regarding their ownership structure, management teams, corporate practices and regulatory compliance, many digital asset platforms do not provide this information. Digital asset platforms may not be subject to, or may not comply with, regulation in a similar manner as other regulated trading platforms, such as national securities exchanges or designated contract markets. As a result, the marketplace may lose confidence in digital asset platforms, including prominent platforms that handle a significant volume of bitcoin trading.

 

Many digital asset platforms are unlicensed, may be unregulated, may be subject to regulation in a relevant jurisdiction, but may or may not be in compliance therewith, may operate without extensive supervision by governmental authorities, and do not provide the public with significant information regarding their ownership structure, management team, corporate practices, cybersecurity, and regulatory compliance. In particular, those located outside the United States may be subject to significantly less stringent regulatory and compliance requirements in their local jurisdictions, and may take the position that they are not subject to laws and regulations that would apply to a national securities exchange or designated contract market in the United States, or may, as a practical matter, be beyond the ambit of U.S. regulators.

 

In addition, over the past several years, some digital asset platforms have been closed due to fraud and manipulative activity, business failure or security breaches. In many of these instances, the customers of such digital asset platforms were not compensated or made whole for the partial or complete losses of their account balances in such digital asset platforms. While, generally speaking, smaller digital asset platforms are less likely to have the infrastructure and capitalization that make larger digital asset platforms more stable, larger digital asset platforms are more likely to be appealing targets for hackers and malware and their shortcomings or ultimate failures are more likely to have contagion effects on the digital asset ecosystem, and therefore may be more likely to be targets of regulatory enforcement action.

 

Negative perception, a lack of stability and standardized regulation in the digital asset markets and the closure or temporary shutdown of digital asset platforms due to fraud, business failure, security breaches or government mandated regulation, and associated losses by customers, may reduce confidence in the Bitcoin network and result in greater volatility or decreases in the prices of bitcoin

 

DIGITAL ASSET REGULATORY RISK. There is a lack of consensus regarding the regulation of digital assets, including bitcoin, and their markets. As a result of the growth in the size of the digital asset market, as well as the 2022 Events, the U.S. Congress and a number of U.S. federal and state agencies (including FinCEN, SEC, OCC, CFTC, FINRA, the Consumer Financial Protection Bureau, the Department of Justice, the Department of Homeland Security, the Federal Bureau of Investigation, the Internal Revenue Service, state financial institution regulators, and others) have been examining the operations of digital asset networks, digital asset users and the digital asset markets. Many of these state and federal agencies have brought enforcement actions or issued consumer advisories regarding the risks posed by digital assets to investors. Ongoing and future regulatory actions with respect to digital assets generally or bitcoin in particular may alter, perhaps to a materially adverse extent, the nature of an investment in the shares of COIN or the ability of COIN to continue to operate.

Risk [Text Block]

NON-DIVERSIFICATION RISK. As a “non-diversified” fund, the Fund may hold a smaller number of portfolio securities than many other funds. To the extent the Fund invests in a relatively small number of issuers, a decline in the market value of a particular security held by the Fund may affect its value more than if it invested in a larger number of issuers. The value of the Fund Shares may be more volatile than the values of shares of more diversified funds.

Roundhill GOOGL WeeklyPay™ ETF | MARKET RISK  
Prospectus [Line Items]  
Risk [Text Block]

MARKET RISK. Market risk is the risk that a particular investment, or Fund Shares in general, may fall in value. Securities are subject to market fluctuations caused by real or perceived adverse economic, political, and regulatory factors or market developments, changes in interest rates, disruptions to trade, impositions of tariffs and perceived trends in securities prices. Fund Shares could decline in value or underperform other investments. In addition, local, regional or global events such as war, acts of terrorism, market manipulation, government defaults, government shutdowns, regulatory actions, political changes, diplomatic developments, the imposition of sanctions and other similar measures, spread of infectious diseases or other public health issues, recessions, natural disasters, or other events could have a significant negative impact on the Fund and its investments. Any of such circumstances could have a materially negative impact on the value of Fund Shares, the liquidity of an investment, and may result in increased market volatility. During any such events, Fund Shares may trade at increased premiums or discounts to their net asset value, the bid/ask spread on Fund Shares may widen and the returns on investment may fluctuate.

Roundhill GOOGL WeeklyPay™ ETF | LIQUIDITY RISK  
Prospectus [Line Items]  
Risk [Text Block]

LIQUIDITY RISK. The market for swap agreements that reference GOOGL shares may be subject to periods of illiquidity. During such times it may be difficult or impossible to buy or sell a position at the desired price. Market disruptions or volatility can also make it difficult to find a counterparty willing to transact at a reasonable price and sufficient size. Illiquid markets may cause losses, which could be significant. The large size of the positions which the Fund may acquire increases the risk of illiquidity, may make its positions more difficult to liquidate, and may increase the losses incurred while trying to do so. Such large positions also may impact the price of swap agreements on GOOGL shares.

Roundhill GOOGL WeeklyPay™ ETF | ACTIVE MANAGEMENT RISK  
Prospectus [Line Items]  
Risk [Text Block]

ACTIVE MANAGEMENT RISK. The Fund is actively-managed and its performance reflects investment decisions that the Adviser and/or Sub-Adviser makes for the Fund. Such judgments about the Fund’s investments may prove to be incorrect. If the investments selected and the strategies employed by the Fund fail to produce the intended results, the Fund could underperform as compared to other funds with similar investment objectives and/or strategies, or could have negative returns.

Roundhill GOOGL WeeklyPay™ ETF | ACTIVE MARKET RISK  
Prospectus [Line Items]  
Risk [Text Block]

ACTIVE MARKET RISK. Although Fund Shares are listed for trading on the Exchange, there can be no assurance that an active trading market for Fund Shares will develop or be maintained. Fund Shares trade on the Exchange at market prices that may be below, at or above the Fund’s net asset value. Securities, including Fund Shares, are subject to market fluctuations and liquidity constraints that may be caused by such factors as economic, political, or regulatory developments, changes in interest rates, and/or perceived trends in securities prices. Fund Shares could decline in value or underperform other investments.

Risk [Text Block]

CONCENTRATION RISK. The Fund is susceptible to an increased risk of loss, including losses due to adverse events that affect the Fund’s investments more than the market as a whole, to the extent that the Fund’s investments are concentrated in investments that provide exposure to GOOGL and the industry to which it is assigned.

Roundhill GOOGL WeeklyPay™ ETF | COUNTERPARTY RISK  
Prospectus [Line Items]  
Risk [Text Block]

COUNTERPARTY RISK. Fund transactions involving a counterparty are subject to the risk that the counterparty will not fulfill its obligation to the Fund. Counterparty risk may arise because of the counterparty’s financial condition (i.e., financial difficulties, bankruptcy, or insolvency), market activities and developments, or other reasons, whether foreseen or not. A counterparty’s inability to fulfill its obligation may result in significant financial loss to the Fund. The Fund may be unable to recover its investment from the counterparty or may obtain a limited recovery, and/or recovery may be delayed.

CREDIT RISK. An issuer or other obligated party of a debt security may be unable or unwilling to make dividend, interest and/or principal payments when due. In addition, the value of a debt security may decline because of concerns about the issuer’s ability or unwillingness to make such payments.

Roundhill GOOGL WeeklyPay™ ETF | CYBERSECURITY RISK  
Prospectus [Line Items]  
Risk [Text Block]

CYBERSECURITY RISK. Failures or breaches of the electronic systems of the Fund, the Fund’s adviser, sub-adviser, distributor and other service providers, market makers, Authorized Participants or the issuers of securities in which the Fund invests have the ability to cause disruptions, negatively impact the Fund’s business operations and/or potentially result in financial losses to the Fund and its shareholders. While the Fund has established business continuity plans and risk management systems seeking to address system breaches or failures, there are inherent limitations in such plans and systems. Furthermore, the Fund cannot control the cybersecurity plans and systems of the Fund’s other service providers, market makers, Authorized Participants or issuers of securities in which the Fund invests.

Roundhill GOOGL WeeklyPay™ ETF | DEBT SECURITIES RISK  
Prospectus [Line Items]  
Risk [Text Block]

DEBT SECURITIES RISK. Investments in debt securities subject the holder to the credit risk of the issuer. Credit risk refers to the possibility that the issuer or other obligor of a security will not be able or willing to make payments of interest and principal when due. Generally, the value of debt securities will change inversely with changes in interest rates. To the extent that interest rates rise, certain underlying obligations may be paid off substantially slower than originally anticipated and the value of those securities may fall sharply. During periods of falling interest rates, the income received by the Fund may decline. If the principal on a debt security is prepaid before expected, the prepayments of principal may have to be reinvested in obligations paying interest at lower rates. Debt securities generally do not trade on a securities exchange making them generally less liquid and more difficult to value than common stock.

Roundhill GOOGL WeeklyPay™ ETF | DERIVATIVES RISK  
Prospectus [Line Items]  
Risk [Text Block]

DERIVATIVES RISK. The use of derivative instruments involves risks different from, or possibly greater than, the risks associated with investing directly in securities and other traditional investments. These risks include: (i) the risk that the counterparty to a derivative transaction may not fulfill its contractual obligations; (ii) risk of mispricing or improper valuation; and (iii) the risk that changes in the value of the derivative may not correlate perfectly with the underlying asset. Derivative prices are highly volatile and may fluctuate substantially during a short period of time. Such prices are influenced by numerous factors that affect the markets, including, but not limited to: changing supply and demand relationships; government programs and policies; national and international political and economic events, changes in interest rates, inflation and deflation and changes in supply and demand relationships. Trading derivative instruments involves risks different from, or possibly greater than, the risks associated with investing directly in securities. Derivative contracts ordinarily have leverage inherent in their terms. The use of leverage may cause the Fund to liquidate portfolio positions when it would not be advantageous to do so in order to satisfy its obligations or to meet regulatory or contractual requirements for derivatives. The use of derivatives can magnify potential for gain or loss and, therefore, amplify the effects of market volatility on share price.

Roundhill GOOGL WeeklyPay™ ETF | DISTRIBUTION TAX RISK  
Prospectus [Line Items]  
Risk [Text Block]

DISTRIBUTION TAX RISK. The Fund currently expects to make distributions on a weekly basis. Such frequent distributions may expose investors to increased tax liabilities. However, these distributions may exceed the Fund’s income and gains for the Fund’s taxable year. Distributions in excess of the Fund’s current and accumulated earnings and profits will be treated as a return of capital. A return of capital distribution generally will not be taxable but will reduce the shareholder’s cost basis and will result in a higher capital gain or lower capital loss when those Fund Shares on which the distribution was received are sold. Once a Fund shareholder’s cost basis is reduced to zero, further distributions will be treated as capital gain if the Fund shareholder holds Fund Shares as capital assets. Additionally, any capital returned through distributions will be distributed after payment of Fund fees and expenses. Because a portion of the Fund’s distributions may consist of return of capital, the Fund may not be an appropriate investment for investors who do not want their principal investment in the Fund to decrease over time or who do not wish to receive return of capital in a given period. In the event that a shareholder purchases Fund Shares shortly before a distribution by the Fund, the entire distribution may be taxable to the shareholder even though a portion of the distribution effectively represents a return of the purchase price.

Roundhill GOOGL WeeklyPay™ ETF | ETF RISK  
Prospectus [Line Items]  
Risk [Text Block]

ETF RISK. The Fund may invest in ETFs. The value of an ETF held by the Fund will fluctuate over time based on fluctuations in the values of the assets held by the ETF, which may be affected by changes in general economic conditions, expectations for future growth and profits, interest rates and the supply and demand for those assets. When the Fund invests in an ETF, it will bear a proportionate share of the ETF’s expenses. Brokerage, tax and other expenses may negatively impact the performance of the ETF and, in turn, the value of the Fund Shares. An ETF that tracks an index may not exactly match the performance of the index due to cash drag, differences between the portfolio of the ETF and the components of the index, expenses and other factors.

Roundhill GOOGL WeeklyPay™ ETF | INFLATION RISK  
Prospectus [Line Items]  
Risk [Text Block]

INFLATION RISK. Inflation risk is the risk that the value of assets or income from investments will be less in the future as inflation decreases the value of money. As inflation increases, the present value of the Fund’s assets and distributions may decline. This risk is more prevalent with respect to fixed income securities held by the Fund.

Roundhill GOOGL WeeklyPay™ ETF | Interest Rate Risk [Member]  
Prospectus [Line Items]  
Risk [Text Block]

INTEREST RATE RISK. Interest rate risk is the risk that the value of the debt securities in the Fund’s portfolio will decline because of rising market interest rates. Interest rate risk is generally lower for shorter term debt securities and higher for longer-term debt securities. Duration is a reasonably accurate measure of a debt security’s price sensitivity to changes in interest rates and a common measure of interest rate risk. Duration measures a debt security’s expected life on a present value basis, taking into account the debt security’s yield, interest payments and final maturity. In general, duration represents the expected percentage change in the value of a security for an immediate 1% change in interest rates. For example, the price of a debt security with a three-year duration would be expected to drop by approximately 3% in response to a 1% increase in interest rates. Therefore, prices of debt securities with shorter durations tend to be less sensitive to interest rate changes than debt securities with longer durations. As the value of a debt security changes over time, so will its duration.

Roundhill GOOGL WeeklyPay™ ETF | LEGISLATION AND LITIGATION RISK  
Prospectus [Line Items]  
Risk [Text Block]

LEGISLATION AND LITIGATION RISK. Legislation or litigation that affects the value of assets or securities held by the Fund may reduce the value of the Fund. From time to time, various legislative initiatives are proposed that may have a negative impact on certain assets or securities in which the Fund invests. In addition, litigation regarding any of the assets or securities owned by the Fund may negatively impact the value of the Shares. Such legislation or litigation may cause the Fund to lose value or may result in higher portfolio turnover if the Adviser determines to sell such a holding.

Roundhill GOOGL WeeklyPay™ ETF | LEVERAGE RISK  
Prospectus [Line Items]  
Risk [Text Block]

LEVERAGE RISK. The Fund obtains investment exposure in excess of its net assets by utilizing leverage and may lose more money in market conditions that are adverse to its investment objectives than a fund that does not utilize leverage. An investment in the Fund is exposed to the risk that a decline in the weekly performance of shares of GOOGL will be magnified. This means that an investment in the Fund will be reduced by an amount equal to 1.2% for every 1% weekly decline in the market value of the GOOGL shares, not including the costs of financing leverage and other operating expenses, which would further reduce its value. The Fund could theoretically lose an amount greater than its net assets in the event the market value of GOOGL shares decline more than 83.33% over a calendar week. Leverage will also have the effect of magnifying any differences in the Fund’s correlation with GOOGL shares.

Roundhill GOOGL WeeklyPay™ ETF | MONEY MARKET INSTRUMENTS RISK  
Prospectus [Line Items]  
Risk [Text Block]

MONEY MARKET INSTRUMENTS RISK. The value of money market instruments may be affected by changing interest rates and by changes in the credit ratings of the investments. If a significant amount of the Fund’s assets are invested in money market instruments, it will be more difficult for the Fund to achieve its investment objectives. An investment in a money market fund is not insured or guaranteed by the FDIC or any other government agency. It is possible to lose money by investing in a money market fund.

Roundhill GOOGL WeeklyPay™ ETF | OPERATIONAL RISK  
Prospectus [Line Items]  
Risk [Text Block]

OPERATIONAL RISK. The Fund is subject to risks arising from various operational factors, including, but not limited to, human error, processing and communication errors, errors of the Fund’s service providers, counterparties or other third-parties, failed or inadequate processes and technology or systems failures. The Fund relies on third-parties for a range of services, including custody. Any delay or failure relating to engaging or maintaining such service providers may affect the Fund’s ability to meet its investment objectives. Although the Fund and the Adviser seek to reduce these operational risks through controls and procedures, there is no way to completely protect against such risks.

Roundhill GOOGL WeeklyPay™ ETF | STRUCTURAL ETF RISKS  
Prospectus [Line Items]  
Risk [Text Block]

STRUCTURAL ETF RISKS. The Fund is an ETF. Accordingly, it is subject to certain risks associated with its unique structure.

 

Market Participants Risk. Only an Authorized Participant may engage in creation or redemption transactions directly with the Fund, and none of those Authorized Participants is obligated to engage in creation and/or redemption transactions. The Fund has a limited number of institutions that may act as Authorized Participants on an agency basis (i.e., on behalf of other market participants). To the extent that Authorized Participants exit the business or are unable to proceed with creation or redemption orders with respect to the Fund and no other Authorized Participant is able to step forward to create or redeem, Fund Shares may be more likely to trade at a premium or discount to NAV and possibly face trading halts or delisting. The Fund may also rely on a small number of third-party market makers to provide a market for the purchase and sale of Fund Shares but such market makers are under no obligation to do so. Decisions by Authorized Participants or market makers to reduce their role or step away from these activities in times of market stress could inhibit the effectiveness of the arbitrage process in maintaining the relationship between the underlying values of the Fund’s portfolio securities and the Fund’s market price. Any trading halt or other problem relating to the trading activity of these market makers or any issues disrupting the Authorized Participants’ ability to proceed with creation and/or redemption orders could result in a dramatic change in the spread between the Fund’s net asset value and the price at which Fund Shares are trading on the Exchange, which could result in a decrease in value of Fund Shares. This reduced effectiveness could result in Fund Shares trading at a premium or discount to net asset value and also in greater than normal intraday bid-ask spreads Fund Shares.

 

Cash Transactions Risk. The Fund currently expects to effect a significant portion of its creations and redemptions for cash, rather than in-kind securities. Paying redemption proceeds in cash rather than through in-kind delivery of portfolio securities may require the Fund to dispose of or sell portfolio securities or other assets at an inopportune time to obtain the cash needed to meet redemption orders. This may cause the Fund to sell a security and recognize a capital gain or loss that might not have been incurred if it had made a redemption in-kind. As a result, the Fund may pay out higher or lower annual capital gains distributions than ETFs that redeem in-kind. The use of cash creations and redemptions may also cause the Fund’s Shares to trade in the market at greater bid-ask spreads or greater premiums or discounts to the Fund’s net asset value (“NAV”). Furthermore, the Fund may not be able to execute cash transactions for creation and redemption purposes at the same price used to determine the Fund’s NAV. To the extent that the maximum additional charge for creation or redemption transactions is insufficient to cover the execution shortfall, the Fund’s performance could be negatively impacted.

 

Costs of Buying and Selling Fund Shares. Due to the costs of buying or selling Fund Shares, including brokerage commissions imposed by brokers and bid/ask spreads, frequent trading of Fund Shares may significantly reduce investment results and an investment in Fund Shares may not be advisable for investors who anticipate regularly making small investments.

 

Premium/Discount Risk. As with all ETFs, Fund Shares may be bought and sold in the secondary market at market prices. The trading prices of Fund Shares in the secondary market may differ from the Fund’s daily NAV per Fund Share and there may be times when the market price of the Fund Shares is more than the NAV per Fund Share (premium) or less than the NAV per Fund Share (discount). If a shareholder purchases Fund Shares at a time when the market price is at a premium to the NAV or sells Fund Shares at a time when the market price is at a discount to the NAV, the shareholder may pay more for, or receive less than, the underlying value of the Fund Shares, respectively. This risk is heightened in times of market volatility or periods of steep market declines.

 

Trading Risks. Although Fund Shares are listed for trading on the Exchange and may be traded on U.S. exchanges other than the Exchange, there can be no assurance that Fund Shares will trade with any volume, or at all, on any stock exchange. In stressed market conditions, the liquidity of Fund Shares may begin to mirror the liquidity of the Fund’s underlying portfolio holdings, which can be significantly less liquid than Fund Shares. Trading in Fund Shares on the Exchange may be halted due to market conditions or for reasons that, in the view of the Exchange, make trading in Fund Shares inadvisable. In addition, trading in Fund Shares on the Exchange is subject to trading halts caused by extraordinary market volatility pursuant to the Exchange’s “circuit breaker” rules. There can be no assurance that the requirements of the Exchange necessary to maintain the listing of the Fund will continue to be met or will remain unchanged.

Roundhill GOOGL WeeklyPay™ ETF | U.S. GOVERNMENT SECURITIES RISK  
Prospectus [Line Items]  
Risk [Text Block]

U.S. GOVERNMENT SECURITIES RISK. U.S. government securities are subject to interest rate risk but generally do not involve the credit risks associated with investments in other types of debt securities. As a result, the yields available from U.S. government securities are generally lower than the yields available from other debt securities. U.S. government securities are guaranteed only as to the timely payment of interest and the payment of principal when held to maturity.

Roundhill GOOGL WeeklyPay™ ETF | VALUATION RISK  
Prospectus [Line Items]  
Risk [Text Block]

VALUATION RISK. The Fund may hold securities or other assets that may be valued on the basis of factors other than market quotations. This may occur because the asset or security does not trade on a centralized exchange, or in times of market turmoil or reduced liquidity. There are multiple methods that can be used to value a portfolio holding when market quotations are not readily available. The value established for any portfolio holding at a point in time might differ from what would be produced using a different methodology or if it had been priced using market quotations. Portfolio holdings that are valued using techniques other than market quotations, including “fair valued” assets or securities, may be subject to greater fluctuation in their valuations from one day to the next than if market quotations were used. In addition, there is no assurance that the Fund could sell or close out a portfolio position for the value established for it at any time, and it is possible that the Fund would incur a loss because a portfolio position is sold or closed out at a discount to the valuation established by the Fund at that time. The Fund’s ability to value investments may be impacted by technological issues or errors by pricing services or other third-party service providers.

Roundhill GOOGL WeeklyPay™ ETF | EQUITY SECURITIES RISK  
Prospectus [Line Items]  
Risk [Text Block]

EQUITY SECURITIES RISK. Equity securities are subject to changes in value, and their values may be more volatile than those of other asset classes. Equity securities prices fluctuate for several reasons, including changes in investors’ perceptions of the financial condition of an issuer or the general condition of the relevant equity market, such as market volatility, or when political or economic events affecting an issuer occur. Common stock prices may be particularly sensitive to rising interest rates, as the cost of capital rises and borrowing costs increase. Common stocks generally subject their holders to more risks than preferred stocks and debt securities because common stockholders’ claims are subordinated to those of holders of preferred stocks and debt securities upon the bankruptcy of the issuer.

Roundhill GOOGL WeeklyPay™ ETF | SWAP AGREEMENTS RISK  
Prospectus [Line Items]  
Risk [Text Block]

SWAP AGREEMENTS RISK. The Fund will utilize swap agreements to derive its exposure to shares of GOOGL. Swap agreements may involve greater risks than direct investment in securities as they may be leveraged and are subject to credit risk, counterparty risk and valuation risk. A swap agreement could result in losses if the underlying reference or asset does not perform as anticipated. In addition, many swaps trade over-the-counter and may be considered illiquid. It may not be possible for the Fund to liquidate a swap position at an advantageous time or price, which may result in significant losses.

Roundhill GOOGL WeeklyPay™ ETF | REGULATED INVESTMENT COMPANY TAX RISKS  
Prospectus [Line Items]  
Risk [Text Block]

REGULATED INVESTMENT COMPANY TAX RISKS. The Fund intends to qualify annually and to elect to be treated as a regulated investment company under the Internal Revenue Code of 1986, as amended (the “Code”). To qualify for the favorable U.S. federal income tax treatment generally accorded to regulated investment companies, the Fund must, among other things, (i) derive in each taxable year at least 90% of its gross income from dividends, interest, payments with respect to securities loans and gains from the sale or other disposition of stock, securities or foreign currencies or other income derived with respect to its business of investing in such stock, securities or currencies, or net income derived from interests in certain publicly traded partnerships; (ii) diversify its holdings so that, at the end of each quarter of the taxable year, (a) at least 50% of the market value of the Fund’s assets is represented by cash and cash items (including receivables), U.S. government securities, the securities of other regulated investment companies and other securities, with such other securities of any one issuer generally limited for the purposes of this calculation to an amount not greater than 5% of the value of the Fund’s total assets and not greater than 10% of the outstanding voting securities of such issuer, and (b) not more than 25% of the value of its total assets is invested in the securities (other than U.S. government securities or the securities of other regulated investment companies) of any one issuer, or two or more issuers which the Fund controls which are engaged in the same, similar or related trades or businesses, or the securities of one or more of certain publicly traded partnerships; and (iii) distribute at least 90% of its investment company taxable income (which includes, among other items, dividends, interest and net short-term capital gains in excess of net long-term capital losses) and at least 90% of its net tax-exempt interest income each taxable year. There are certain exceptions for failure to qualify if the failure is for reasonable cause or is de minimis, and certain corrective action is taken and certain tax payments are made by the Fund.

 

If the Fund were to fail to meet the qualifying income test or asset diversification test and fail to qualify as a RIC, it would be taxed in the same manner as an ordinary corporation, and distributions to its shareholders would not be deductible by the Fund in computing its taxable income, which would adversely affect the Fund’s performance.

Roundhill GOOGL WeeklyPay™ ETF | LARGE SHAREHOLDER RISK  
Prospectus [Line Items]  
Risk [Text Block]

LARGE SHAREHOLDER RISK. Certain shareholders, including affiliated funds advised by the Adviser, may from time to time own a significant portion of the Fund’s shares. In addition, a third-party investor, the Adviser or an affiliate of the Adviser (“Affiliate”), an authorized participant, a market maker, or another entity may invest in the Fund and hold its investment for a limited period solely to facilitate the commencement of the Fund or to help the Fund achieve a specified size or scale. There can be no assurance that any large shareholder will not redeem its investment, that the size of the Fund will be maintained at such levels, or that the Fund will continue to meet applicable listing requirements. Redemptions by large shareholders could have a significant negative impact on the Fund. In addition, transactions by large shareholders may account for a large percentage of the trading volume on the Fund’s listing exchange and may, therefore, have a material upward or downward effect on the market price of the shares.

 

To the extent that a significant percentage of the Fund’s shares are owned or controlled by a small number of account shareholders (or a single account shareholder), including funds or accounts over which the Adviser or an Affiliate has investment discretion, the Fund is subject to the risk that those shareholders may purchase or redeem Fund shares in significant amounts rapidly or unexpectedly, including as a result of an asset allocation decision made by the Adviser or an Affiliate. This may adversely affect the Fund’s performance if the Adviser is forced to sell portfolio securities or invest cash when it would not otherwise choose to do so. Redemptions of a large number of shares may affect the liquidity of the Fund’s portfolio, increase the Fund’s transaction costs, and accelerate the realization of taxable income and/or gains. In addition, a large redemption could result in the Fund’s current expenses being allocated over a smaller asset base, leading to an increase in the Fund’s gross expense ratio. Large purchases of the Fund’s shares may also adversely affect the Fund’s performance to the extent that the Fund is delayed in investing new cash or otherwise maintains a larger cash position than it ordinarily would, particularly if the Fund accepts cash for an order for the purchase of creation units of the Fund’s shares.

Roundhill GOOGL WeeklyPay™ ETF | GOOGL INVESTING RISKS  
Prospectus [Line Items]  
Risk [Text Block]

GOOGL INVESTING RISKS. The Fund will have significant exposure to GOOGL through its investments in swap agreements that utilize GOOGL as the reference asset. Accordingly, the Fund will subject to the risks of GOOGL, set forth below.

 

GOOGL ISSUER-SPECIFIC RISKS. Issuer-specific attributes may cause an investment held by the Fund to be more volatile than the market generally. The value of an individual security or particular type of security may be more volatile than the market as a whole and may perform differently from the value of the market as a whole. As of the date of this prospectus, in addition to the risks associated with companies in the technology sector, GOOGL faces risks associated with: reliance on advertising revenue and the effect that loss of partners or new and existing technologies that block advertisements online may have on its business; intense competition for its products and services across different industries; investments in new businesses, products, services and technologies that may divert management attention or harm its financial condition or operating results; slowdowns in its revenue growth rate; the ability to protect its intellectual property rights; the ability to maintain or enhance its brands and its impact on the ability to expand its user base, advertisers, customers, content providers and other partners; manufacturing and supply chain issues; interruptions to, or interferences with, its complex technology and communication systems; its international operations; fluctuations in the fair values of its investments and in some instances, the subjective nature of some of the valuation methodologies used in its financial statements; failure to evolve with the advancement of technology and user preferences; data privacy and security concerns; problematic content posted on its platforms by users; increased restriction or charges related to each user’s ability to access the content provided by the company; as well as regulatory, legal and litigation issues.

 

COMMUNICATION SERVICES COMPANIES RISK. Companies in the communication services sector may be affected by industry competition, substantial capital requirements, government regulation, and obsolescence of communications products and services due to technological advancement. Fluctuating domestic and international demand, shifting demographics and often unpredictable changes in consumer tastes can drastically affect a communication services company’s profitability. In addition, while all companies may be susceptible to network security breaches, certain companies in the communication services sector may be particular targets of hacking and potential theft of proprietary or consumer information or disruptions in service, which could have a material adverse effect on their businesses.

 

The communication services sector of a country’s economy is often subject to extensive government regulation. The costs of complying with governmental regulations, delays or failure to receive required regulatory approvals, or the enactment of new regulatory requirements may negatively affect the business of communications companies. Government actions around the world, specifically in the area of pre-marketing clearance of products and prices, can be arbitrary and unpredictable. The communications services industry can also be significantly affected by intense competition for market share, including competition with alternative technologies such as wireless communications, product compatibility and standardization, consumer preferences, rapid product obsolescence, research and development of new products, lack of standardization or compatibility with existing technologies, and a dependency on patent and copyright protections. Companies in the communication services sector may encounter distressed cash flows due to the need to commit substantial capital to meet increasing competition, particularly in developing new products and services using new technology. Technological innovations may make the products and services of certain communications companies obsolete.

 

INDIRECT INVESTMENT RISK. Alphabet, Inc. is not affiliated with the Trust, the Fund, the Adviser, the Sub-Adviser or any affiliates thereof and is not involved with this offering in any way, and has no obligation to consider the Fund in taking any corporate actions that might affect the value of the Fund. The Trust, the Fund, the Adviser, the Sub-Adviser or any affiliate are not responsible for the performance of GOOGL and make no representation as to the performance of GOOGL. Investing in the Fund is not equivalent to investing in GOOGL. Fund shareholders will not have voting rights or rights to receive dividends or other distributions or any other rights with respect to GOOGL.

 

LARGE CAPITALIZATION COMPANIES RISK. Large capitalization companies may be less able than smaller capitalization companies to adapt to changing market conditions. Large capitalization companies may be more mature and subject to more limited growth potential compared with smaller capitalization companies. During different market cycles, the performance of large capitalization companies has trailed the overall performance of the broader securities markets.

 

UNITED STATES RISK. Certain changes in the U.S. economy, such as when the U.S. economy weakens or when its financial markets decline, may have an adverse effect on the securities to which the Fund has exposure.

NON-DIVERSIFICATION RISK. As a “non-diversified” fund, the Fund may hold a smaller number of portfolio securities than many other funds. To the extent the Fund invests in a relatively small number of issuers, a decline in the market value of a particular security held by the Fund may affect its value more than if it invested in a larger number of issuers. The value of the Fund Shares may be more volatile than the values of shares of more diversified funds.

Roundhill META WeeklyPay™ ETF | MARKET RISK

MARKET RISK. Market risk is the risk that a particular investment, or Fund Shares in general, may fall in value. Securities are subject to market fluctuations caused by real or perceived adverse economic, political, and regulatory factors or market developments, changes in interest rates, disruptions to trade, impositions of tariffs and perceived trends in securities prices. Fund Shares could decline in value or underperform other investments. In addition, local, regional or global events such as war, acts of terrorism, market manipulation, government defaults, government shutdowns, regulatory actions, political changes, diplomatic developments, the imposition of sanctions and other similar measures, spread of infectious diseases or other public health issues, recessions, natural disasters, or other events could have a significant negative impact on the Fund and its investments. Any of such circumstances could have a materially negative impact on the value of Fund Shares, the liquidity of an investment, and may result in increased market volatility. During any such events, Fund Shares may trade at increased premiums or discounts to their net asset value, the bid/ask spread on Fund Shares may widen and the returns on investment may fluctuate.

LIQUIDITY RISK. The market for swap agreements that reference META shares may be subject to periods of illiquidity. During such times it may be difficult or impossible to buy or sell a position at the desired price. Market disruptions or volatility can also make it difficult to find a counterparty willing to transact at a reasonable price and sufficient size. Illiquid markets may cause losses, which could be significant. The large size of the positions which the Fund may acquire increases the risk of illiquidity, may make its positions more difficult to liquidate, and may increase the losses incurred while trying to do so. Such large positions also may impact the price of swap agreements on META shares.

Roundhill META WeeklyPay™ ETF | ACTIVE MANAGEMENT RISK

ACTIVE MANAGEMENT RISK. The Fund is actively-managed and its performance reflects investment decisions that the Adviser and/or Sub-Adviser makes for the Fund. Such judgments about the Fund’s investments may prove to be incorrect. If the investments selected and the strategies employed by the Fund fail to produce the intended results, the Fund could underperform as compared to other funds with similar investment objectives and/or strategies, or could have negative returns.

Roundhill META WeeklyPay™ ETF | ACTIVE MARKET RISK

ACTIVE MARKET RISK. Although Fund Shares are listed for trading on the Exchange, there can be no assurance that an active trading market for Fund Shares will develop or be maintained. Fund Shares trade on the Exchange at market prices that may be below, at or above the Fund’s net asset value. Securities, including Fund Shares, are subject to market fluctuations and liquidity constraints that may be caused by such factors as economic, political, or regulatory developments, changes in interest rates, and/or perceived trends in securities prices. Fund Shares could decline in value or underperform other investments.

CONCENTRATION RISK. The Fund is susceptible to an increased risk of loss, including losses due to adverse events that affect the Fund’s investments more than the market as a whole, to the extent that the Fund’s investments are concentrated in investments that provide exposure to META and the industry to which it is assigned.

Roundhill META WeeklyPay™ ETF | COUNTERPARTY RISK  
Prospectus [Line Items]  
Risk [Text Block]

COUNTERPARTY RISK. Fund transactions involving a counterparty are subject to the risk that the counterparty will not fulfill its obligation to the Fund. Counterparty risk may arise because of the counterparty’s financial condition (i.e., financial difficulties, bankruptcy, or insolvency), market activities and developments, or other reasons, whether foreseen or not. A counterparty’s inability to fulfill its obligation may result in significant financial loss to the Fund. The Fund may be unable to recover its investment from the counterparty or may obtain a limited recovery, and/or recovery may be delayed.

CREDIT RISK. An issuer or other obligated party of a debt security may be unable or unwilling to make dividend, interest and/or principal payments when due. In addition, the value of a debt security may decline because of concerns about the issuer’s ability or unwillingness to make such payments.

Roundhill META WeeklyPay™ ETF | CYBERSECURITY RISK  
Prospectus [Line Items]  
Risk [Text Block]

CYBERSECURITY RISK. Failures or breaches of the electronic systems of the Fund, the Fund’s adviser, sub-adviser, distributor and other service providers, market makers, Authorized Participants or the issuers of securities in which the Fund invests have the ability to cause disruptions, negatively impact the Fund’s business operations and/or potentially result in financial losses to the Fund and its shareholders. While the Fund has established business continuity plans and risk management systems seeking to address system breaches or failures, there are inherent limitations in such plans and systems. Furthermore, the Fund cannot control the cybersecurity plans and systems of the Fund’s other service providers, market makers, Authorized Participants or issuers of securities in which the Fund invests.

Roundhill META WeeklyPay™ ETF | DEBT SECURITIES RISK  
Prospectus [Line Items]  
Risk [Text Block]

DEBT SECURITIES RISK. Investments in debt securities subject the holder to the credit risk of the issuer. Credit risk refers to the possibility that the issuer or other obligor of a security will not be able or willing to make payments of interest and principal when due. Generally, the value of debt securities will change inversely with changes in interest rates. To the extent that interest rates rise, certain underlying obligations may be paid off substantially slower than originally anticipated and the value of those securities may fall sharply. During periods of falling interest rates, the income received by the Fund may decline. If the principal on a debt security is prepaid before expected, the prepayments of principal may have to be reinvested in obligations paying interest at lower rates. Debt securities generally do not trade on a securities exchange making them generally less liquid and more difficult to value than common stock.

Roundhill META WeeklyPay™ ETF | DERIVATIVES RISK  
Prospectus [Line Items]  
Risk [Text Block]

DERIVATIVES RISK. The use of derivative instruments involves risks different from, or possibly greater than, the risks associated with investing directly in securities and other traditional investments. These risks include: (i) the risk that the counterparty to a derivative transaction may not fulfill its contractual obligations; (ii) risk of mispricing or improper valuation; and (iii) the risk that changes in the value of the derivative may not correlate perfectly with the underlying asset. Derivative prices are highly volatile and may fluctuate substantially during a short period of time. Such prices are influenced by numerous factors that affect the markets, including, but not limited to: changing supply and demand relationships; government programs and policies; national and international political and economic events, changes in interest rates, inflation and deflation and changes in supply and demand relationships. Trading derivative instruments involves risks different from, or possibly greater than, the risks associated with investing directly in securities. Derivative contracts ordinarily have leverage inherent in their terms. The use of leverage may cause the Fund to liquidate portfolio positions when it would not be advantageous to do so in order to satisfy its obligations or to meet regulatory or contractual requirements for derivatives. The use of derivatives can magnify potential for gain or loss and, therefore, amplify the effects of market volatility on share price.

Roundhill META WeeklyPay™ ETF | DISTRIBUTION TAX RISK  
Prospectus [Line Items]  
Risk [Text Block]

DISTRIBUTION TAX RISK. The Fund currently expects to make distributions on a weekly basis. Such frequent distributions may expose investors to increased tax liabilities. However, these distributions may exceed the Fund’s income and gains for the Fund’s taxable year. Distributions in excess of the Fund’s current and accumulated earnings and profits will be treated as a return of capital. A return of capital distribution generally will not be taxable but will reduce the shareholder’s cost basis and will result in a higher capital gain or lower capital loss when those Fund Shares on which the distribution was received are sold. Once a Fund shareholder’s cost basis is reduced to zero, further distributions will be treated as capital gain if the Fund shareholder holds Fund Shares as capital assets. Additionally, any capital returned through distributions will be distributed after payment of Fund fees and expenses. Because a portion of the Fund’s distributions may consist of return of capital, the Fund may not be an appropriate investment for investors who do not want their principal investment in the Fund to decrease over time or who do not wish to receive return of capital in a given period. In the event that a shareholder purchases Fund Shares shortly before a distribution by the Fund, the entire distribution may be taxable to the shareholder even though a portion of the distribution effectively represents a return of the purchase price.

Roundhill META WeeklyPay™ ETF | ETF RISK  
Prospectus [Line Items]  
Risk [Text Block]

ETF RISK. The Fund may invest in ETFs. The value of an ETF held by the Fund will fluctuate over time based on fluctuations in the values of the assets held by the ETF, which may be affected by changes in general economic conditions, expectations for future growth and profits, interest rates and the supply and demand for those assets. When the Fund invests in an ETF, it will bear a proportionate share of the ETF’s expenses. Brokerage, tax and other expenses may negatively impact the performance of the ETF and, in turn, the value of the Fund Shares. An ETF that tracks an index may not exactly match the performance of the index due to cash drag, differences between the portfolio of the ETF and the components of the index, expenses and other factors.

Roundhill META WeeklyPay™ ETF | INFLATION RISK  
Prospectus [Line Items]  
Risk [Text Block]

INFLATION RISK. Inflation risk is the risk that the value of assets or income from investments will be less in the future as inflation decreases the value of money. As inflation increases, the present value of the Fund’s assets and distributions may decline. This risk is more prevalent with respect to fixed income securities held by the Fund.

Roundhill META WeeklyPay™ ETF | Interest Rate Risk [Member]  
Prospectus [Line Items]  
Risk [Text Block]

INTEREST RATE RISK. Interest rate risk is the risk that the value of the debt securities in the Fund’s portfolio will decline because of rising market interest rates. Interest rate risk is generally lower for shorter term debt securities and higher for longer-term debt securities. Duration is a reasonably accurate measure of a debt security’s price sensitivity to changes in interest rates and a common measure of interest rate risk. Duration measures a debt security’s expected life on a present value basis, taking into account the debt security’s yield, interest payments and final maturity. In general, duration represents the expected percentage change in the value of a security for an immediate 1% change in interest rates. For example, the price of a debt security with a three-year duration would be expected to drop by approximately 3% in response to a 1% increase in interest rates. Therefore, prices of debt securities with shorter durations tend to be less sensitive to interest rate changes than debt securities with longer durations. As the value of a debt security changes over time, so will its duration.

Roundhill META WeeklyPay™ ETF | LEGISLATION AND LITIGATION RISK  
Prospectus [Line Items]  
Risk [Text Block]

LEGISLATION AND LITIGATION RISK. Legislation or litigation that affects the value of assets or securities held by the Fund may reduce the value of the Fund. From time to time, various legislative initiatives are proposed that may have a negative impact on certain assets or securities in which the Fund invests. In addition, litigation regarding any of the assets or securities owned by the Fund may negatively impact the value of the Shares. Such legislation or litigation may cause the Fund to lose value or may result in higher portfolio turnover if the Adviser determines to sell such a holding.

Roundhill META WeeklyPay™ ETF | LEVERAGE RISK  
Prospectus [Line Items]  
Risk [Text Block]

LEVERAGE RISK. The Fund obtains investment exposure in excess of its net assets by utilizing leverage and may lose more money in market conditions that are adverse to its investment objectives than a fund that does not utilize leverage. An investment in the Fund is exposed to the risk that a decline in the weekly performance of shares of META will be magnified. This means that an investment in the Fund will be reduced by an amount equal to 1.2% for every 1% weekly decline in the market value of the META shares, not including the costs of financing leverage and other operating expenses, which would further reduce its value. The Fund could theoretically lose an amount greater than its net assets in the event the market value of META shares decline more than 83.33% over a calendar week. Leverage will also have the effect of magnifying any differences in the Fund’s correlation with META shares.

Roundhill META WeeklyPay™ ETF | MONEY MARKET INSTRUMENTS RISK  
Prospectus [Line Items]  
Risk [Text Block]

MONEY MARKET INSTRUMENTS RISK. The value of money market instruments may be affected by changing interest rates and by changes in the credit ratings of the investments. If a significant amount of the Fund’s assets are invested in money market instruments, it will be more difficult for the Fund to achieve its investment objectives. An investment in a money market fund is not insured or guaranteed by the FDIC or any other government agency. It is possible to lose money by investing in a money market fund.

Roundhill META WeeklyPay™ ETF | OPERATIONAL RISK  
Prospectus [Line Items]  
Risk [Text Block]

OPERATIONAL RISK. The Fund is subject to risks arising from various operational factors, including, but not limited to, human error, processing and communication errors, errors of the Fund’s service providers, counterparties or other third-parties, failed or inadequate processes and technology or systems failures. The Fund relies on third-parties for a range of services, including custody. Any delay or failure relating to engaging or maintaining such service providers may affect the Fund’s ability to meet its investment objectives. Although the Fund and the Adviser seek to reduce these operational risks through controls and procedures, there is no way to completely protect against such risks.

Roundhill META WeeklyPay™ ETF | SPECIAL TAX RISK  
Prospectus [Line Items]  
Risk [Text Block]

SPECIAL TAX RISK. The Fund intends to qualify annually and to elect to be treated as a regulated investment company under the Internal Revenue Code of 1986, as amended (the “Code”). To qualify for the favorable U.S. federal income tax treatment generally accorded to regulated investment companies, the Fund must, among other things, (i) derive in each taxable year at least 90% of its gross income from dividends, interest, payments with respect to securities loans and gains from the sale or other disposition of stock, securities or foreign currencies or other income derived with respect to its business of investing in such stock, securities or currencies, or net income derived from interests in certain publicly traded partnerships; (ii) diversify its holdings so that, at the end of each quarter of the taxable year, (a) at least 50% of the market value of the Fund’s assets is represented by cash and cash items (including receivables), U.S. government securities, the securities of other regulated investment companies and other securities, with such other securities of any one issuer generally limited for the purposes of this calculation to an amount not greater than 5% of the value of the Fund’s total assets and not greater than 10% of the outstanding voting securities of such issuer, and (b) not more than 25% of the value of its total assets is invested in the securities (other than U.S. government securities or the securities of other regulated investment companies) of any one issuer, or two or more issuers which the Fund controls which are engaged in the same, similar or related trades or businesses, or the securities of one or more of certain publicly traded partnerships; and (iii) distribute at least 90% of its investment company taxable income (which includes, among other items, dividends, interest and net short-term capital gains in excess of net long-term capital losses) and at least 90% of its net tax-exempt interest income each taxable year. There are certain exceptions for failure to qualify if the failure is for reasonable cause or is de minimis, and certain corrective action is taken and certain tax payments are made by the Fund.

 

The authority with regard to swaps entered into by regulated investment companies is unclear both as to the qualification under the income test and the identification of the issuer under the diversification test. The Fund intends to take the position that because the swaps held by the Fund reference securities that the income on the swaps are “other income” from the Fund’s business of investing in stocks and securities. In addition, the Fund intends to manage its investments in the swaps so that neither the exposure to issuer of the referenced security nor the exposure to any one counterparty of the swaps will exceed 25% of the gross value of the Fund’s portfolio at the end of any quarter.

 

If the Fund were to fail to meet the qualifying income test or asset diversification test and fail to qualify as a RIC, it would be taxed in the same manner as an ordinary corporation, and distributions to its shareholders would not be deductible by the Fund in computing its taxable income, which would adversely affect the Fund’s performance.

Roundhill META WeeklyPay™ ETF | STRUCTURAL ETF RISKS  
Prospectus [Line Items]  
Risk [Text Block]

STRUCTURAL ETF RISKS. The Fund is an ETF. Accordingly, it is subject to certain risks associated with its unique structure.

 

Market Participants Risk. Only an Authorized Participant may engage in creation or redemption transactions directly with the Fund, and none of those Authorized Participants is obligated to engage in creation and/or redemption transactions. The Fund has a limited number of institutions that may act as Authorized Participants on an agency basis (i.e., on behalf of other market participants). To the extent that Authorized Participants exit the business or are unable to proceed with creation or redemption orders with respect to the Fund and no other Authorized Participant is able to step forward to create or redeem, Fund Shares may be more likely to trade at a premium or discount to NAV and possibly face trading halts or delisting. The Fund may also rely on a small number of third-party market makers to provide a market for the purchase and sale of Fund Shares but such market makers are under no obligation to do so. Decisions by Authorized Participants or market makers to reduce their role or step away from these activities in times of market stress could inhibit the effectiveness of the arbitrage process in maintaining the relationship between the underlying values of the Fund’s portfolio securities and the Fund’s market price. Any trading halt or other problem relating to the trading activity of these market makers or any issues disrupting the Authorized Participants’ ability to proceed with creation and/or redemption orders could result in a dramatic change in the spread between the Fund’s net asset value and the price at which Fund Shares are trading on the Exchange, which could result in a decrease in value of Fund Shares. This reduced effectiveness could result in Fund Shares trading at a premium or discount to net asset value and also in greater than normal intraday bid-ask spreads Fund Shares.

 

Cash Transactions Risk. The Fund currently expects to effect a significant portion of its creations and redemptions for cash, rather than in-kind securities. Paying redemption proceeds in cash rather than through in-kind delivery of portfolio securities may require the Fund to dispose of or sell portfolio securities or other assets at an inopportune time to obtain the cash needed to meet redemption orders. This may cause the Fund to sell a security and recognize a capital gain or loss that might not have been incurred if it had made a redemption in-kind. As a result, the Fund may pay out higher or lower annual capital gains distributions than ETFs that redeem in-kind. The use of cash creations and redemptions may also cause the Fund’s Shares to trade in the market at greater bid-ask spreads or greater premiums or discounts to the Fund’s net asset value (“NAV”). Furthermore, the Fund may not be able to execute cash transactions for creation and redemption purposes at the same price used to determine the Fund’s NAV. To the extent that the maximum additional charge for creation or redemption transactions is insufficient to cover the execution shortfall, the Fund’s performance could be negatively impacted.

 

Costs of Buying and Selling Fund Shares. Due to the costs of buying or selling Fund Shares, including brokerage commissions imposed by brokers and bid/ask spreads, frequent trading of Fund Shares may significantly reduce investment results and an investment in Fund Shares may not be advisable for investors who anticipate regularly making small investments.

 

Premium/Discount Risk. As with all ETFs, Fund Shares may be bought and sold in the secondary market at market prices. The trading prices of Fund Shares in the secondary market may differ from the Fund’s daily NAV per Fund Share and there may be times when the market price of the Fund Shares is more than the NAV per Fund Share (premium) or less than the NAV per Fund Share (discount). If a shareholder purchases Fund Shares at a time when the market price is at a premium to the NAV or sells Fund Shares at a time when the market price is at a discount to the NAV, the shareholder may pay more for, or receive less than, the underlying value of the Fund Shares, respectively. This risk is heightened in times of market volatility or periods of steep market declines.

 

Trading Risks. Although Fund Shares are listed for trading on the Exchange and may be traded on U.S. exchanges other than the Exchange, there can be no assurance that Fund Shares will trade with any volume, or at all, on any stock exchange. In stressed market conditions, the liquidity of Fund Shares may begin to mirror the liquidity of the Fund’s underlying portfolio holdings, which can be significantly less liquid than Fund Shares. Trading in Fund Shares on the Exchange may be halted due to market conditions or for reasons that, in the view of the Exchange, make trading in Fund Shares inadvisable. In addition, trading in Fund Shares on the Exchange is subject to trading halts caused by extraordinary market volatility pursuant to the Exchange’s “circuit breaker” rules. There can be no assurance that the requirements of the Exchange necessary to maintain the listing of the Fund will continue to be met or will remain unchanged.

Roundhill META WeeklyPay™ ETF | U.S. GOVERNMENT SECURITIES RISK  
Prospectus [Line Items]  
Risk [Text Block]

U.S. GOVERNMENT SECURITIES RISK. U.S. government securities are subject to interest rate risk but generally do not involve the credit risks associated with investments in other types of debt securities. As a result, the yields available from U.S. government securities are generally lower than the yields available from other debt securities. U.S. government securities are guaranteed only as to the timely payment of interest and the payment of principal when held to maturity.

Roundhill META WeeklyPay™ ETF | VALUATION RISK  
Prospectus [Line Items]  
Risk [Text Block]

VALUATION RISK. The Fund may hold securities or other assets that may be valued on the basis of factors other than market quotations. This may occur because the asset or security does not trade on a centralized exchange, or in times of market turmoil or reduced liquidity. There are multiple methods that can be used to value a portfolio holding when market quotations are not readily available. The value established for any portfolio holding at a point in time might differ from what would be produced using a different methodology or if it had been priced using market quotations. Portfolio holdings that are valued using techniques other than market quotations, including “fair valued” assets or securities, may be subject to greater fluctuation in their valuations from one day to the next than if market quotations were used. In addition, there is no assurance that the Fund could sell or close out a portfolio position for the value established for it at any time, and it is possible that the Fund would incur a loss because a portfolio position is sold or closed out at a discount to the valuation established by the Fund at that time. The Fund’s ability to value investments may be impacted by technological issues or errors by pricing services or other third-party service providers.

Roundhill META WeeklyPay™ ETF | EQUITY SECURITIES RISK  
Prospectus [Line Items]  
Risk [Text Block]

EQUITY SECURITIES RISK. Equity securities are subject to changes in value, and their values may be more volatile than those of other asset classes. Equity securities prices fluctuate for several reasons, including changes in investors’ perceptions of the financial condition of an issuer or the general condition of the relevant equity market, such as market volatility, or when political or economic events affecting an issuer occur. Common stock prices may be particularly sensitive to rising interest rates, as the cost of capital rises and borrowing costs increase. Common stocks generally subject their holders to more risks than preferred stocks and debt securities because common stockholders’ claims are subordinated to those of holders of preferred stocks and debt securities upon the bankruptcy of the issuer.

Roundhill META WeeklyPay™ ETF | SWAP AGREEMENTS RISK  
Prospectus [Line Items]  
Risk [Text Block]

SWAP AGREEMENTS RISK. The Fund will utilize swap agreements to derive its exposure to shares of META. Swap agreements may involve greater risks than direct investment in securities as they may be leveraged and are subject to credit risk, counterparty risk and valuation risk. A swap agreement could result in losses if the underlying reference or asset does not perform as anticipated. In addition, many swaps trade over-the-counter and may be considered illiquid. It may not be possible for the Fund to liquidate a swap position at an advantageous time or price, which may result in significant losses.

Roundhill META WeeklyPay™ ETF | REGULATED INVESTMENT COMPANY TAX RISKS  
Prospectus [Line Items]  
Risk [Text Block]

REGULATED INVESTMENT COMPANY TAX RISKS. The Fund intends to qualify annually and to elect to be treated as a regulated investment company under the Internal Revenue Code of 1986, as amended (the “Code”). To qualify for the favorable U.S. federal income tax treatment generally accorded to regulated investment companies, the Fund must, among other things, (i) derive in each taxable year at least 90% of its gross income from dividends, interest, payments with respect to securities loans and gains from the sale or other disposition of stock, securities or foreign currencies or other income derived with respect to its business of investing in such stock, securities or currencies, or net income derived from interests in certain publicly traded partnerships; (ii) diversify its holdings so that, at the end of each quarter of the taxable year, (a) at least 50% of the market value of the Fund’s assets is represented by cash and cash items (including receivables), U.S. government securities, the securities of other regulated investment companies and other securities, with such other securities of any one issuer generally limited for the purposes of this calculation to an amount not greater than 5% of the value of the Fund’s total assets and not greater than 10% of the outstanding voting securities of such issuer, and (b) not more than 25% of the value of its total assets is invested in the securities (other than U.S. government securities or the securities of other regulated investment companies) of any one issuer, or two or more issuers which the Fund controls which are engaged in the same, similar or related trades or businesses, or the securities of one or more of certain publicly traded partnerships; and (iii) distribute at least 90% of its investment company taxable income (which includes, among other items, dividends, interest and net short-term capital gains in excess of net long-term capital losses) and at least 90% of its net tax-exempt interest income each taxable year. There are certain exceptions for failure to qualify if the failure is for reasonable cause or is de minimis, and certain corrective action is taken and certain tax payments are made by the Fund.

 

If the Fund were to fail to meet the qualifying income test or asset diversification test and fail to qualify as a RIC, it would be taxed in the same manner as an ordinary corporation, and distributions to its shareholders would not be deductible by the Fund in computing its taxable income, which would adversely affect the Fund’s performance.

Roundhill META WeeklyPay™ ETF | LARGE SHAREHOLDER RISK  
Prospectus [Line Items]  
Risk [Text Block]

LARGE SHAREHOLDER RISK. Certain shareholders, including affiliated funds advised by the Adviser, may from time to time own a significant portion of the Fund’s shares. In addition, a third-party investor, the Adviser or an affiliate of the Adviser (“Affiliate”), an authorized participant, a market maker, or another entity may invest in the Fund and hold its investment for a limited period solely to facilitate the commencement of the Fund or to help the Fund achieve a specified size or scale. There can be no assurance that any large shareholder will not redeem its investment, that the size of the Fund will be maintained at such levels, or that the Fund will continue to meet applicable listing requirements. Redemptions by large shareholders could have a significant negative impact on the Fund. In addition, transactions by large shareholders may account for a large percentage of the trading volume on the Fund’s listing exchange and may, therefore, have a material upward or downward effect on the market price of the shares.

 

To the extent that a significant percentage of the Fund’s shares are owned or controlled by a small number of account shareholders (or a single account shareholder), including funds or accounts over which the Adviser or an Affiliate has investment discretion, the Fund is subject to the risk that those shareholders may purchase or redeem Fund shares in significant amounts rapidly or unexpectedly, including as a result of an asset allocation decision made by the Adviser or an Affiliate. This may adversely affect the Fund’s performance if the Adviser is forced to sell portfolio securities or invest cash when it would not otherwise choose to do so. Redemptions of a large number of shares may affect the liquidity of the Fund’s portfolio, increase the Fund’s transaction costs, and accelerate the realization of taxable income and/or gains. In addition, a large redemption could result in the Fund’s current expenses being allocated over a smaller asset base, leading to an increase in the Fund’s gross expense ratio. Large purchases of the Fund’s shares may also adversely affect the Fund’s performance to the extent that the Fund is delayed in investing new cash or otherwise maintains a larger cash position than it ordinarily would, particularly if the Fund accepts cash for an order for the purchase of creation units of the Fund’s shares.

Roundhill META WeeklyPay™ ETF | META INVESTING RISKS  
Prospectus [Line Items]  
Risk [Text Block]

META INVESTING RISKS. The Fund will have significant exposure to META through its investments in swap agreements that utilize META as the reference asset. Accordingly, the Fund will subject to the risks of META, set forth below.

 

META ISSUER-SPECIFIC RISKS. Issuer-specific attributes may cause an investment held by the Fund to be more volatile than the market generally. The value of an individual security or particular type of security may be more volatile than the market as a whole and may perform differently from the value of the market as a whole. As of the date of this prospectus, Meta Platforms, Inc. offers social media-related products such as Facebook, Instagram, Messenger, Threads and WhatsApp as well as certain augmented and virtual reality products. Meta Platforms, Inc. is subject to a number of risks, including, among others: risks related to its product offerings, such as its ability to add or retain users and to increase advertising spending, including the risks associated with not being successful in artificial intelligence (“AI”) initiatives although the company is making significant investment in AI; business operations and financial results, including the ability to compete effectively in the highly competitive information technology sector; government regulation and enforcement, including any restrictions on access to Meta Platform, Inc.’s products, especially in regard to AI; the ability to collect and use consumer data, including the phasing out of third-party cookies which the company has historically used to gauge success of various ads and will impact monetization; data, security and intellectual property, including the occurrences of security breaches or improper access of consumer data; and the dual class structure of the company’s common stock, which limits the ability of shareholders to influence corporate matters.

 

COMMUNICATION SERVICES COMPANIES RISK. Companies in the communication services sector may be affected by industry competition, substantial capital requirements, government regulation, and obsolescence of communications products and services due to technological advancement. Fluctuating domestic and international demand, shifting demographics and often unpredictable changes in consumer tastes can drastically affect a communication services company’s profitability. In addition, while all companies may be susceptible to network security breaches, certain companies in the communication services sector may be particular targets of hacking and potential theft of proprietary or consumer information or disruptions in service, which could have a material adverse effect on their businesses.

 

The communication services sector of a country’s economy is often subject to extensive government regulation. The costs of complying with governmental regulations, delays or failure to receive required regulatory approvals, or the enactment of new regulatory requirements may negatively affect the business of communications companies. Government actions around the world, specifically in the area of pre-marketing clearance of products and prices, can be arbitrary and unpredictable. The communications services industry can also be significantly affected by intense competition for market share, including competition with alternative technologies such as wireless communications, product compatibility and standardization, consumer preferences, rapid product obsolescence, research and development of new products, lack of standardization or compatibility with existing technologies, and a dependency on patent and copyright protections. Companies in the communication services sector may encounter distressed cash flows due to the need to commit substantial capital to meet increasing competition, particularly in developing new products and services using new technology. Technological innovations may make the products and services of certain communications companies obsolete.

 

INDIRECT INVESTMENT RISK. Meta Platforms, Inc. is not affiliated with the Trust, the Fund, the Adviser, the Sub-Adviser or any affiliates thereof and is not involved with this offering in any way, and has no obligation to consider the Fund in taking any corporate actions that might affect the value of the Fund. The Trust, the Fund, the Adviser, the Sub-Adviser or any affiliate are not responsible for the performance of META and make no representation as to the performance of META. Investing in the Fund is not equivalent to investing in META. Fund shareholders will not have voting rights or rights to receive dividends or other distributions or any other rights with respect to META.

 

LARGE CAPITALIZATION COMPANIES RISK. Large capitalization companies may be less able than smaller capitalization companies to adapt to changing market conditions. Large capitalization companies may be more mature and subject to more limited growth potential compared with smaller capitalization companies. During different market cycles, the performance of large capitalization companies has trailed the overall performance of the broader securities markets.

 

UNITED STATES RISK. Certain changes in the U.S. economy, such as when the U.S. economy weakens or when its financial markets decline, may have an adverse effect on the securities to which the Fund has exposure.

NON-DIVERSIFICATION RISK. As a “non-diversified” fund, the Fund may hold a smaller number of portfolio securities than many other funds. To the extent the Fund invests in a relatively small number of issuers, a decline in the market value of a particular security held by the Fund may affect its value more than if it invested in a larger number of issuers. The value of the Fund Shares may be more volatile than the values of shares of more diversified funds.

Roundhill MSFT WeeklyPay™ ETF | MARKET RISK  
Prospectus [Line Items]  
Risk [Text Block]

MARKET RISK. Market risk is the risk that a particular investment, or Fund Shares in general, may fall in value. Securities are subject to market fluctuations caused by real or perceived adverse economic, political, and regulatory factors or market developments, changes in interest rates, disruptions to trade, impositions of tariffs and perceived trends in securities prices. Fund Shares could decline in value or underperform other investments. In addition, local, regional or global events such as war, acts of terrorism, market manipulation, government defaults, government shutdowns, regulatory actions, political changes, diplomatic developments, the imposition of sanctions and other similar measures, spread of infectious diseases or other public health issues, recessions, natural disasters, or other events could have a significant negative impact on the Fund and its investments. Any of such circumstances could have a materially negative impact on the value of Fund Shares, the liquidity of an investment, and may result in increased market volatility. During any such events, Fund Shares may trade at increased premiums or discounts to their net asset value, the bid/ask spread on Fund Shares may widen and the returns on investment may fluctuate.

Roundhill MSFT WeeklyPay™ ETF | LIQUIDITY RISK

Risk [Text Block]

LIQUIDITY RISK. The market for swap agreements that reference MSFT shares may be subject to periods of illiquidity. During such times it may be difficult or impossible to buy or sell a position at the desired price. Market disruptions or volatility can also make it difficult to find a counterparty willing to transact at a reasonable price and sufficient size. Illiquid markets may cause losses, which could be significant. The large size of the positions which the Fund may acquire increases the risk of illiquidity, may make its positions more difficult to liquidate, and may increase the losses incurred while trying to do so. Such large positions also may impact the price of swap agreements on MSFT shares.

Roundhill MSFT WeeklyPay™ ETF | ACTIVE MANAGEMENT RISK  
Prospectus [Line Items]  
Risk [Text Block]

ACTIVE MANAGEMENT RISK. The Fund is actively-managed and its performance reflects investment decisions that the Adviser and/or Sub-Adviser makes for the Fund. Such judgments about the Fund’s investments may prove to be incorrect. If the investments selected and the strategies employed by the Fund fail to produce the intended results, the Fund could underperform as compared to other funds with similar investment objectives and/or strategies, or could have negative returns.

Roundhill MSFT WeeklyPay™ ETF | ACTIVE MARKET RISK

Risk [Text Block]

ACTIVE MARKET RISK. Although Fund Shares are listed for trading on the Exchange, there can be no assurance that an active trading market for Fund Shares will develop or be maintained. Fund Shares trade on the Exchange at market prices that may be below, at or above the Fund’s net asset value. Securities, including Fund Shares, are subject to market fluctuations and liquidity constraints that may be caused by such factors as economic, political, or regulatory developments, changes in interest rates, and/or perceived trends in securities prices. Fund Shares could decline in value or underperform other investments.

CONCENTRATION RISK. The Fund is susceptible to an increased risk of loss, including losses due to adverse events that affect the Fund’s investments more than the market as a whole, to the extent that the Fund’s investments are concentrated in investments that provide exposure to MSFT and the industry to which it is assigned.

Roundhill MSFT WeeklyPay™ ETF | COUNTERPARTY RISK  
Prospectus [Line Items]  
Risk [Text Block]

COUNTERPARTY RISK. Fund transactions involving a counterparty are subject to the risk that the counterparty will not fulfill its obligation to the Fund. Counterparty risk may arise because of the counterparty’s financial condition (i.e., financial difficulties, bankruptcy, or insolvency), market activities and developments, or other reasons, whether foreseen or not. A counterparty’s inability to fulfill its obligation may result in significant financial loss to the Fund. The Fund may be unable to recover its investment from the counterparty or may obtain a limited recovery, and/or recovery may be delayed.

CREDIT RISK. An issuer or other obligated party of a debt security may be unable or unwilling to make dividend, interest and/or principal payments when due. In addition, the value of a debt security may decline because of concerns about the issuer’s ability or unwillingness to make such payments.

Roundhill MSFT WeeklyPay™ ETF | CYBERSECURITY RISK  
Prospectus [Line Items]  
Risk [Text Block]

CYBERSECURITY RISK. Failures or breaches of the electronic systems of the Fund, the Fund’s adviser, sub-adviser, distributor and other service providers, market makers, Authorized Participants or the issuers of securities in which the Fund invests have the ability to cause disruptions, negatively impact the Fund’s business operations and/or potentially result in financial losses to the Fund and its shareholders. While the Fund has established business continuity plans and risk management systems seeking to address system breaches or failures, there are inherent limitations in such plans and systems. Furthermore, the Fund cannot control the cybersecurity plans and systems of the Fund’s other service providers, market makers, Authorized Participants or issuers of securities in which the Fund invests.

Roundhill MSFT WeeklyPay™ ETF | DEBT SECURITIES RISK  
Prospectus [Line Items]  
Risk [Text Block]

DEBT SECURITIES RISK. Investments in debt securities subject the holder to the credit risk of the issuer. Credit risk refers to the possibility that the issuer or other obligor of a security will not be able or willing to make payments of interest and principal when due. Generally, the value of debt securities will change inversely with changes in interest rates. To the extent that interest rates rise, certain underlying obligations may be paid off substantially slower than originally anticipated and the value of those securities may fall sharply. During periods of falling interest rates, the income received by the Fund may decline. If the principal on a debt security is prepaid before expected, the prepayments of principal may have to be reinvested in obligations paying interest at lower rates. Debt securities generally do not trade on a securities exchange making them generally less liquid and more difficult to value than common stock.

Roundhill MSFT WeeklyPay™ ETF | DERIVATIVES RISK  
Prospectus [Line Items]  
Risk [Text Block]

DERIVATIVES RISK. The use of derivative instruments involves risks different from, or possibly greater than, the risks associated with investing directly in securities and other traditional investments. These risks include: (i) the risk that the counterparty to a derivative transaction may not fulfill its contractual obligations; (ii) risk of mispricing or improper valuation; and (iii) the risk that changes in the value of the derivative may not correlate perfectly with the underlying asset. Derivative prices are highly volatile and may fluctuate substantially during a short period of time. Such prices are influenced by numerous factors that affect the markets, including, but not limited to: changing supply and demand relationships; government programs and policies; national and international political and economic events, changes in interest rates, inflation and deflation and changes in supply and demand relationships. Trading derivative instruments involves risks different from, or possibly greater than, the risks associated with investing directly in securities. Derivative contracts ordinarily have leverage inherent in their terms. The use of leverage may cause the Fund to liquidate portfolio positions when it would not be advantageous to do so in order to satisfy its obligations or to meet regulatory or contractual requirements for derivatives. The use of derivatives can magnify potential for gain or loss and, therefore, amplify the effects of market volatility on share price.

Roundhill MSFT WeeklyPay™ ETF | DISTRIBUTION TAX RISK  
Prospectus [Line Items]  
Risk [Text Block]

DISTRIBUTION TAX RISK. The Fund currently expects to make distributions on a weekly basis. Such frequent distributions may expose investors to increased tax liabilities. However, these distributions may exceed the Fund’s income and gains for the Fund’s taxable year. Distributions in excess of the Fund’s current and accumulated earnings and profits will be treated as a return of capital. A return of capital distribution generally will not be taxable but will reduce the shareholder’s cost basis and will result in a higher capital gain or lower capital loss when those Fund Shares on which the distribution was received are sold. Once a Fund shareholder’s cost basis is reduced to zero, further distributions will be treated as capital gain if the Fund shareholder holds Fund Shares as capital assets. Additionally, any capital returned through distributions will be distributed after payment of Fund fees and expenses. Because a portion of the Fund’s distributions may consist of return of capital, the Fund may not be an appropriate investment for investors who do not want their principal investment in the Fund to decrease over time or who do not wish to receive return of capital in a given period. In the event that a shareholder purchases Fund Shares shortly before a distribution by the Fund, the entire distribution may be taxable to the shareholder even though a portion of the distribution effectively represents a return of the purchase price.

Roundhill MSFT WeeklyPay™ ETF | ETF RISK  
Prospectus [Line Items]  
Risk [Text Block]

ETF RISK. The Fund may invest in ETFs. The value of an ETF held by the Fund will fluctuate over time based on fluctuations in the values of the assets held by the ETF, which may be affected by changes in general economic conditions, expectations for future growth and profits, interest rates and the supply and demand for those assets. When the Fund invests in an ETF, it will bear a proportionate share of the ETF’s expenses. Brokerage, tax and other expenses may negatively impact the performance of the ETF and, in turn, the value of the Fund Shares. An ETF that tracks an index may not exactly match the performance of the index due to cash drag, differences between the portfolio of the ETF and the components of the index, expenses and other factors.

Roundhill MSFT WeeklyPay™ ETF | INFLATION RISK  
Prospectus [Line Items]  
Risk [Text Block]

INFLATION RISK. Inflation risk is the risk that the value of assets or income from investments will be less in the future as inflation decreases the value of money. As inflation increases, the present value of the Fund’s assets and distributions may decline. This risk is more prevalent with respect to fixed income securities held by the Fund.

Roundhill MSFT WeeklyPay™ ETF | Interest Rate Risk [Member]  
Prospectus [Line Items]  
Risk [Text Block]

INTEREST RATE RISK. Interest rate risk is the risk that the value of the debt securities in the Fund’s portfolio will decline because of rising market interest rates. Interest rate risk is generally lower for shorter term debt securities and higher for longer-term debt securities. Duration is a reasonably accurate measure of a debt security’s price sensitivity to changes in interest rates and a common measure of interest rate risk. Duration measures a debt security’s expected life on a present value basis, taking into account the debt security’s yield, interest payments and final maturity. In general, duration represents the expected percentage change in the value of a security for an immediate 1% change in interest rates. For example, the price of a debt security with a three-year duration would be expected to drop by approximately 3% in response to a 1% increase in interest rates. Therefore, prices of debt securities with shorter durations tend to be less sensitive to interest rate changes than debt securities with longer durations. As the value of a debt security changes over time, so will its duration.

Roundhill MSFT WeeklyPay™ ETF | LEGISLATION AND LITIGATION RISK  
Prospectus [Line Items]  
Risk [Text Block]

LEGISLATION AND LITIGATION RISK. Legislation or litigation that affects the value of assets or securities held by the Fund may reduce the value of the Fund. From time to time, various legislative initiatives are proposed that may have a negative impact on certain assets or securities in which the Fund invests. In addition, litigation regarding any of the assets or securities owned by the Fund may negatively impact the value of the Shares. Such legislation or litigation may cause the Fund to lose value or may result in higher portfolio turnover if the Adviser determines to sell such a holding.

Roundhill MSFT WeeklyPay™ ETF | LEVERAGE RISK  
Prospectus [Line Items]  
Risk [Text Block]

LEVERAGE RISK. The Fund obtains investment exposure in excess of its net assets by utilizing leverage and may lose more money in market conditions that are adverse to its investment objectives than a fund that does not utilize leverage. An investment in the Fund is exposed to the risk that a decline in the weekly performance of shares of MSFT will be magnified. This means that an investment in the Fund will be reduced by an amount equal to 1.2% for every 1% weekly decline in the market value of the MSFT shares, not including the costs of financing leverage and other operating expenses, which would further reduce its value. The Fund could theoretically lose an amount greater than its net assets in the event the market value of MSFT shares decline more than 83.33% over a calendar week. Leverage will also have the effect of magnifying any differences in the Fund’s correlation with MSFT shares.

Roundhill MSFT WeeklyPay™ ETF | MONEY MARKET INSTRUMENTS RISK  
Prospectus [Line Items]  
Risk [Text Block]

MONEY MARKET INSTRUMENTS RISK. The value of money market instruments may be affected by changing interest rates and by changes in the credit ratings of the investments. If a significant amount of the Fund’s assets are invested in money market instruments, it will be more difficult for the Fund to achieve its investment objectives. An investment in a money market fund is not insured or guaranteed by the FDIC or any other government agency. It is possible to lose money by investing in a money market fund.

Roundhill MSFT WeeklyPay™ ETF | OPERATIONAL RISK  
Prospectus [Line Items]  
Risk [Text Block]

OPERATIONAL RISK. The Fund is subject to risks arising from various operational factors, including, but not limited to, human error, processing and communication errors, errors of the Fund’s service providers, counterparties or other third-parties, failed or inadequate processes and technology or systems failures. The Fund relies on third-parties for a range of services, including custody. Any delay or failure relating to engaging or maintaining such service providers may affect the Fund’s ability to meet its investment objectives. Although the Fund and the Adviser seek to reduce these operational risks through controls and procedures, there is no way to completely protect against such risks.

Roundhill MSFT WeeklyPay™ ETF | SPECIAL TAX RISK  
Prospectus [Line Items]  
Risk [Text Block]

SPECIAL TAX RISK. The Fund intends to qualify annually and to elect to be treated as a regulated investment company under the Internal Revenue Code of 1986, as amended (the “Code”). To qualify for the favorable U.S. federal income tax treatment generally accorded to regulated investment companies, the Fund must, among other things, (i) derive in each taxable year at least 90% of its gross income from dividends, interest, payments with respect to securities loans and gains from the sale or other disposition of stock, securities or foreign currencies or other income derived with respect to its business of investing in such stock, securities or currencies, or net income derived from interests in certain publicly traded partnerships; (ii) diversify its holdings so that, at the end of each quarter of the taxable year, (a) at least 50% of the market value of the Fund’s assets is represented by cash and cash items (including receivables), U.S. government securities, the securities of other regulated investment companies and other securities, with such other securities of any one issuer generally limited for the purposes of this calculation to an amount not greater than 5% of the value of the Fund’s total assets and not greater than 10% of the outstanding voting securities of such issuer, and (b) not more than 25% of the value of its total assets is invested in the securities (other than U.S. government securities or the securities of other regulated investment companies) of any one issuer, or two or more issuers which the Fund controls which are engaged in the same, similar or related trades or businesses, or the securities of one or more of certain publicly traded partnerships; and (iii) distribute at least 90% of its investment company taxable income (which includes, among other items, dividends, interest and net short-term capital gains in excess of net long-term capital losses) and at least 90% of its net tax-exempt interest income each taxable year. There are certain exceptions for failure to qualify if the failure is for reasonable cause or is de minimis, and certain corrective action is taken and certain tax payments are made by the Fund.

 

The authority with regard to swaps entered into by regulated investment companies is unclear both as to the qualification under the income test and the identification of the issuer under the diversification test. The Fund intends to take the position that because the swaps held by the Fund reference securities that the income on the swaps are “other income” from the Fund’s business of investing in stocks and securities. In addition, the Fund intends to manage its investments in the swaps so that neither the exposure to issuer of the referenced security nor the exposure to any one counterparty of the swaps will exceed 25% of the gross value of the Fund’s portfolio at the end of any quarter.

 

If the Fund were to fail to meet the qualifying income test or asset diversification test and fail to qualify as a RIC, it would be taxed in the same manner as an ordinary corporation, and distributions to its shareholders would not be deductible by the Fund in computing its taxable income, which would adversely affect the Fund’s performance.

Roundhill MSFT WeeklyPay™ ETF | STRUCTURAL ETF RISKS  
Prospectus [Line Items]  
Risk [Text Block]

STRUCTURAL ETF RISKS. The Fund is an ETF. Accordingly, it is subject to certain risks associated with its unique structure.

 

Market Participants Risk. Only an Authorized Participant may engage in creation or redemption transactions directly with the Fund, and none of those Authorized Participants is obligated to engage in creation and/or redemption transactions. The Fund has a limited number of institutions that may act as Authorized Participants on an agency basis (i.e., on behalf of other market participants). To the extent that Authorized Participants exit the business or are unable to proceed with creation or redemption orders with respect to the Fund and no other Authorized Participant is able to step forward to create or redeem, Fund Shares may be more likely to trade at a premium or discount to NAV and possibly face trading halts or delisting. The Fund may also rely on a small number of third-party market makers to provide a market for the purchase and sale of Fund Shares but such market makers are under no obligation to do so. Decisions by Authorized Participants or market makers to reduce their role or step away from these activities in times of market stress could inhibit the effectiveness of the arbitrage process in maintaining the relationship between the underlying values of the Fund’s portfolio securities and the Fund’s market price. Any trading halt or other problem relating to the trading activity of these market makers or any issues disrupting the Authorized Participants’ ability to proceed with creation and/or redemption orders could result in a dramatic change in the spread between the Fund’s net asset value and the price at which Fund Shares are trading on the Exchange, which could result in a decrease in value of Fund Shares. This reduced effectiveness could result in Fund Shares trading at a premium or discount to net asset value and also in greater than normal intraday bid-ask spreads Fund Shares.

 

Cash Transactions Risk. The Fund currently expects to effect a significant portion of its creations and redemptions for cash, rather than in-kind securities. Paying redemption proceeds in cash rather than through in-kind delivery of portfolio securities may require the Fund to dispose of or sell portfolio securities or other assets at an inopportune time to obtain the cash needed to meet redemption orders. This may cause the Fund to sell a security and recognize a capital gain or loss that might not have been incurred if it had made a redemption in-kind. As a result, the Fund may pay out higher or lower annual capital gains distributions than ETFs that redeem in-kind. The use of cash creations and redemptions may also cause the Fund’s Shares to trade in the market at greater bid-ask spreads or greater premiums or discounts to the Fund’s net asset value (“NAV”). Furthermore, the Fund may not be able to execute cash transactions for creation and redemption purposes at the same price used to determine the Fund’s NAV. To the extent that the maximum additional charge for creation or redemption transactions is insufficient to cover the execution shortfall, the Fund’s performance could be negatively impacted.

 

Costs of Buying and Selling Fund Shares. Due to the costs of buying or selling Fund Shares, including brokerage commissions imposed by brokers and bid/ask spreads, frequent trading of Fund Shares may significantly reduce investment results and an investment in Fund Shares may not be advisable for investors who anticipate regularly making small investments.

 

Premium/Discount Risk. As with all ETFs, Fund Shares may be bought and sold in the secondary market at market prices. The trading prices of Fund Shares in the secondary market may differ from the Fund’s daily NAV per Fund Share and there may be times when the market price of the Fund Shares is more than the NAV per Fund Share (premium) or less than the NAV per Fund Share (discount). If a shareholder purchases Fund Shares at a time when the market price is at a premium to the NAV or sells Fund Shares at a time when the market price is at a discount to the NAV, the shareholder may pay more for, or receive less than, the underlying value of the Fund Shares, respectively. This risk is heightened in times of market volatility or periods of steep market declines.

 

Trading Risks. Although Fund Shares are listed for trading on the Exchange and may be traded on U.S. exchanges other than the Exchange, there can be no assurance that Fund Shares will trade with any volume, or at all, on any stock exchange. In stressed market conditions, the liquidity of Fund Shares may begin to mirror the liquidity of the Fund’s underlying portfolio holdings, which can be significantly less liquid than Fund Shares. Trading in Fund Shares on the Exchange may be halted due to market conditions or for reasons that, in the view of the Exchange, make trading in Fund Shares inadvisable. In addition, trading in Fund Shares on the Exchange is subject to trading halts caused by extraordinary market volatility pursuant to the Exchange’s “circuit breaker” rules. There can be no assurance that the requirements of the Exchange necessary to maintain the listing of the Fund will continue to be met or will remain unchanged.

Roundhill MSFT WeeklyPay™ ETF | U.S. GOVERNMENT SECURITIES RISK  
Prospectus [Line Items]  
Risk [Text Block]

U.S. GOVERNMENT SECURITIES RISK. U.S. government securities are subject to interest rate risk but generally do not involve the credit risks associated with investments in other types of debt securities. As a result, the yields available from U.S. government securities are generally lower than the yields available from other debt securities. U.S. government securities are guaranteed only as to the timely payment of interest and the payment of principal when held to maturity.

Roundhill MSFT WeeklyPay™ ETF | VALUATION RISK  
Prospectus [Line Items]  
Risk [Text Block]

VALUATION RISK. The Fund may hold securities or other assets that may be valued on the basis of factors other than market quotations. This may occur because the asset or security does not trade on a centralized exchange, or in times of market turmoil or reduced liquidity. There are multiple methods that can be used to value a portfolio holding when market quotations are not readily available. The value established for any portfolio holding at a point in time might differ from what would be produced using a different methodology or if it had been priced using market quotations. Portfolio holdings that are valued using techniques other than market quotations, including “fair valued” assets or securities, may be subject to greater fluctuation in their valuations from one day to the next than if market quotations were used. In addition, there is no assurance that the Fund could sell or close out a portfolio position for the value established for it at any time, and it is possible that the Fund would incur a loss because a portfolio position is sold or closed out at a discount to the valuation established by the Fund at that time. The Fund’s ability to value investments may be impacted by technological issues or errors by pricing services or other third-party service providers.

Roundhill MSFT WeeklyPay™ ETF | EQUITY SECURITIES RISK  
Prospectus [Line Items]  
Risk [Text Block]

EQUITY SECURITIES RISK. Equity securities are subject to changes in value, and their values may be more volatile than those of other asset classes. Equity securities prices fluctuate for several reasons, including changes in investors’ perceptions of the financial condition of an issuer or the general condition of the relevant equity market, such as market volatility, or when political or economic events affecting an issuer occur. Common stock prices may be particularly sensitive to rising interest rates, as the cost of capital rises and borrowing costs increase. Common stocks generally subject their holders to more risks than preferred stocks and debt securities because common stockholders’ claims are subordinated to those of holders of preferred stocks and debt securities upon the bankruptcy of the issuer.

Roundhill MSFT WeeklyPay™ ETF | SWAP AGREEMENTS RISK  
Prospectus [Line Items]  
Risk [Text Block]

SWAP AGREEMENTS RISK. The Fund will utilize swap agreements to derive its exposure to shares of MSFT. Swap agreements may involve greater risks than direct investment in securities as they may be leveraged and are subject to credit risk, counterparty risk and valuation risk. A swap agreement could result in losses if the underlying reference or asset does not perform as anticipated. In addition, many swaps trade over-the-counter and may be considered illiquid. It may not be possible for the Fund to liquidate a swap position at an advantageous time or price, which may result in significant losses.

Roundhill MSFT WeeklyPay™ ETF | REGULATED INVESTMENT COMPANY TAX RISKS  
Prospectus [Line Items]  
Risk [Text Block]

REGULATED INVESTMENT COMPANY TAX RISKS. The Fund intends to qualify annually and to elect to be treated as a regulated investment company under the Internal Revenue Code of 1986, as amended (the “Code”). To qualify for the favorable U.S. federal income tax treatment generally accorded to regulated investment companies, the Fund must, among other things, (i) derive in each taxable year at least 90% of its gross income from dividends, interest, payments with respect to securities loans and gains from the sale or other disposition of stock, securities or foreign currencies or other income derived with respect to its business of investing in such stock, securities or currencies, or net income derived from interests in certain publicly traded partnerships; (ii) diversify its holdings so that, at the end of each quarter of the taxable year, (a) at least 50% of the market value of the Fund’s assets is represented by cash and cash items (including receivables), U.S. government securities, the securities of other regulated investment companies and other securities, with such other securities of any one issuer generally limited for the purposes of this calculation to an amount not greater than 5% of the value of the Fund’s total assets and not greater than 10% of the outstanding voting securities of such issuer, and (b) not more than 25% of the value of its total assets is invested in the securities (other than U.S. government securities or the securities of other regulated investment companies) of any one issuer, or two or more issuers which the Fund controls which are engaged in the same, similar or related trades or businesses, or the securities of one or more of certain publicly traded partnerships; and (iii) distribute at least 90% of its investment company taxable income (which includes, among other items, dividends, interest and net short-term capital gains in excess of net long-term capital losses) and at least 90% of its net tax-exempt interest income each taxable year. There are certain exceptions for failure to qualify if the failure is for reasonable cause or is de minimis, and certain corrective action is taken and certain tax payments are made by the Fund.

 

If the Fund were to fail to meet the qualifying income test or asset diversification test and fail to qualify as a RIC, it would be taxed in the same manner as an ordinary corporation, and distributions to its shareholders would not be deductible by the Fund in computing its taxable income, which would adversely affect the Fund’s performance.

Roundhill MSFT WeeklyPay™ ETF | LARGE SHAREHOLDER RISK  
Prospectus [Line Items]  
Risk [Text Block]

LARGE SHAREHOLDER RISK. Certain shareholders, including affiliated funds advised by the Adviser, may from time to time own a significant portion of the Fund’s shares. In addition, a third-party investor, the Adviser or an affiliate of the Adviser (“Affiliate”), an authorized participant, a market maker, or another entity may invest in the Fund and hold its investment for a limited period solely to facilitate the commencement of the Fund or to help the Fund achieve a specified size or scale. There can be no assurance that any large shareholder will not redeem its investment, that the size of the Fund will be maintained at such levels, or that the Fund will continue to meet applicable listing requirements. Redemptions by large shareholders could have a significant negative impact on the Fund. In addition, transactions by large shareholders may account for a large percentage of the trading volume on the Fund’s listing exchange and may, therefore, have a material upward or downward effect on the market price of the shares.

 

To the extent that a significant percentage of the Fund’s shares are owned or controlled by a small number of account shareholders (or a single account shareholder), including funds or accounts over which the Adviser or an Affiliate has investment discretion, the Fund is subject to the risk that those shareholders may purchase or redeem Fund shares in significant amounts rapidly or unexpectedly, including as a result of an asset allocation decision made by the Adviser or an Affiliate. This may adversely affect the Fund’s performance if the Adviser is forced to sell portfolio securities or invest cash when it would not otherwise choose to do so. Redemptions of a large number of shares may affect the liquidity of the Fund’s portfolio, increase the Fund’s transaction costs, and accelerate the realization of taxable income and/or gains. In addition, a large redemption could result in the Fund’s current expenses being allocated over a smaller asset base, leading to an increase in the Fund’s gross expense ratio. Large purchases of the Fund’s shares may also adversely affect the Fund’s performance to the extent that the Fund is delayed in investing new cash or otherwise maintains a larger cash position than it ordinarily would, particularly if the Fund accepts cash for an order for the purchase of creation units of the Fund’s shares.

Roundhill MSFT WeeklyPay™ ETF | MSFT INVESTING RISKS  
Prospectus [Line Items]  
Risk [Text Block]

MSFT INVESTING RISKS. The Fund will have significant exposure to MSFT through its investments in swap agreements that utilize MSFT as the reference asset. Accordingly, the Fund will subject to the risks of MSFT, set forth below.

 

MSFT ISSUER-SPECIFIC RISKS. Issuer-specific attributes may cause an investment held by the Fund to be more volatile than the market generally. The value of an individual security or particular type of security may be more volatile than the market as a whole and may perform differently from the value of the market as a whole. As of the date of this prospectus, in addition to the risks associated with companies in the information technology sector, Microsoft Corporation faces risks associated with: damage or harm to its reputation, brand or business and operations; adverse market conditions, including those related to catastrophic events or geopolitical conditions; global business exposure; the ability to attract and retain talented employees; competition in the technology sector and among platform based ecosystems, including its increasing focus on cloud-based services; the evolution of its business, including the development of its new products and acquisitions, joint ventures and strategic alliances; significant investment may occur on products and services that do not achieve their expected results; impairment of goodwill or amortized intangible assets may require significant changes to reported earnings; development of the Internet of Things (IoT) artificial intelligence (AI) may result in reputational or competitive harm; cybersecurity, data privacy and platform abuses; operations, including excessive outages, data losses or disruptions of online services; quality or supply problems; as well as legal, intellectual property, regulatory and litigation risks, including those related to the development of the IoT and AI.

 

INDIRECT INVESTMENT RISK. Microsoft Corporation is not affiliated with the Trust, the Fund, the Adviser, the Sub-Adviser or any affiliates thereof and is not involved with this offering in any way, and has no obligation to consider the Fund in taking any corporate actions that might affect the value of the Fund. The Trust, the Fund, the Adviser, the Sub-Adviser or any affiliate are not responsible for the performance of MSFT and make no representation as to the performance of MSFT. Investing in the Fund is not equivalent to investing in MSFT. Fund shareholders will not have voting rights or rights to receive dividends or other distributions or any other rights with respect to MSFT.

 

INFORMATION TECHNOLOGY COMPANIES RISK. Information technology companies face intense competition, both domestically and internationally, which may have an adverse effect on profit margins. Like other technology companies, information technology companies may have limited product lines, markets, financial resources or personnel. The products of information technology companies may face obsolescence due to rapid technological developments, frequent new product introduction, unpredictable changes in growth rates and competition for the services of qualified personnel. Companies in the information technology sector are heavily dependent on patent and intellectual property rights. The loss or impairment of these rights may adversely affect the profitability of these companies. Information technology companies are facing increased government and regulatory scrutiny and may be subject to adverse government or regulatory action.

 

LARGE CAPITALIZATION COMPANIES RISK. Large capitalization companies may be less able than smaller capitalization companies to adapt to changing market conditions. Large capitalization companies may be more mature and subject to more limited growth potential compared with smaller capitalization companies. During different market cycles, the performance of large capitalization companies has trailed the overall performance of the broader securities markets.

 

UNITED STATES RISK. Certain changes in the U.S. economy, such as when the U.S. economy weakens or when its financial markets decline, may have an adverse effect on the securities to which the Fund has exposure.

NON-DIVERSIFICATION RISK. As a “non-diversified” fund, the Fund may hold a smaller number of portfolio securities than many other funds. To the extent the Fund invests in a relatively small number of issuers, a decline in the market value of a particular security held by the Fund may affect its value more than if it invested in a larger number of issuers. The value of the Fund Shares may be more volatile than the values of shares of more diversified funds.

MARKET RISK. Market risk is the risk that a particular investment, or Fund Shares in general, may fall in value. Securities are subject to market fluctuations caused by real or perceived adverse economic, political, and regulatory factors or market developments, changes in interest rates, disruptions to trade, impositions of tariffs and perceived trends in securities prices. Fund Shares could decline in value or underperform other investments. In addition, local, regional or global events such as war, acts of terrorism, market manipulation, government defaults, government shutdowns, regulatory actions, political changes, diplomatic developments, the imposition of sanctions and other similar measures, spread of infectious diseases or other public health issues, recessions, natural disasters, or other events could have a significant negative impact on the Fund and its investments. Any of such circumstances could have a materially negative impact on the value of Fund Shares, the liquidity of an investment, and may result in increased market volatility. During any such events, Fund Shares may trade at increased premiums or discounts to their net asset value, the bid/ask spread on Fund Shares may widen and the returns on investment may fluctuate.

Roundhill PLTR WeeklyPay™ ETF | LIQUIDITY RISK

Risk [Text Block]

LIQUIDITY RISK. The market for swap agreements that reference PLTR shares may be subject to periods of illiquidity. During such times it may be difficult or impossible to buy or sell a position at the desired price. Market disruptions or volatility can also make it difficult to find a counterparty willing to transact at a reasonable price and sufficient size. Illiquid markets may cause losses, which could be significant. The large size of the positions which the Fund may acquire increases the risk of illiquidity, may make its positions more difficult to liquidate, and may increase the losses incurred while trying to do so. Such large positions also may impact the price of swap agreements on PLTR shares.

Roundhill PLTR WeeklyPay™ ETF | ACTIVE MANAGEMENT RISK  
Prospectus [Line Items]  
Risk [Text Block]

ACTIVE MANAGEMENT RISK. The Fund is actively-managed and its performance reflects investment decisions that the Adviser and/or Sub-Adviser makes for the Fund. Such judgments about the Fund’s investments may prove to be incorrect. If the investments selected and the strategies employed by the Fund fail to produce the intended results, the Fund could underperform as compared to other funds with similar investment objectives and/or strategies, or could have negative returns.

Roundhill PLTR WeeklyPay™ ETF | ACTIVE MARKET RISK

Risk [Text Block]

ACTIVE MARKET RISK. Although Fund Shares are listed for trading on the Exchange, there can be no assurance that an active trading market for Fund Shares will develop or be maintained. Fund Shares trade on the Exchange at market prices that may be below, at or above the Fund’s net asset value. Securities, including Fund Shares, are subject to market fluctuations and liquidity constraints that may be caused by such factors as economic, political, or regulatory developments, changes in interest rates, and/or perceived trends in securities prices. Fund Shares could decline in value or underperform other investments.

Risk [Text Block]

CONCENTRATION RISK. The Fund is susceptible to an increased risk of loss, including losses due to adverse events that affect the Fund’s investments more than the market as a whole, to the extent that the Fund’s investments are concentrated in investments that provide exposure to PLTR and the industry to which it is assigned.

Roundhill PLTR WeeklyPay™ ETF | COUNTERPARTY RISK  
Prospectus [Line Items]  
Risk [Text Block]

COUNTERPARTY RISK. Fund transactions involving a counterparty are subject to the risk that the counterparty will not fulfill its obligation to the Fund. Counterparty risk may arise because of the counterparty’s financial condition (i.e., financial difficulties, bankruptcy, or insolvency), market activities and developments, or other reasons, whether foreseen or not. A counterparty’s inability to fulfill its obligation may result in significant financial loss to the Fund. The Fund may be unable to recover its investment from the counterparty or may obtain a limited recovery, and/or recovery may be delayed.

CREDIT RISK. An issuer or other obligated party of a debt security may be unable or unwilling to make dividend, interest and/or principal payments when due. In addition, the value of a debt security may decline because of concerns about the issuer’s ability or unwillingness to make such payments.

Roundhill PLTR WeeklyPay™ ETF | CYBERSECURITY RISK  
Prospectus [Line Items]  
Risk [Text Block]

CYBERSECURITY RISK. Failures or breaches of the electronic systems of the Fund, the Fund’s adviser, sub-adviser, distributor and other service providers, market makers, Authorized Participants or the issuers of securities in which the Fund invests have the ability to cause disruptions, negatively impact the Fund’s business operations and/or potentially result in financial losses to the Fund and its shareholders. While the Fund has established business continuity plans and risk management systems seeking to address system breaches or failures, there are inherent limitations in such plans and systems. Furthermore, the Fund cannot control the cybersecurity plans and systems of the Fund’s other service providers, market makers, Authorized Participants or issuers of securities in which the Fund invests.

Roundhill PLTR WeeklyPay™ ETF | DEBT SECURITIES RISK  
Prospectus [Line Items]  
Risk [Text Block]

DEBT SECURITIES RISK. Investments in debt securities subject the holder to the credit risk of the issuer. Credit risk refers to the possibility that the issuer or other obligor of a security will not be able or willing to make payments of interest and principal when due. Generally, the value of debt securities will change inversely with changes in interest rates. To the extent that interest rates rise, certain underlying obligations may be paid off substantially slower than originally anticipated and the value of those securities may fall sharply. During periods of falling interest rates, the income received by the Fund may decline. If the principal on a debt security is prepaid before expected, the prepayments of principal may have to be reinvested in obligations paying interest at lower rates. Debt securities generally do not trade on a securities exchange making them generally less liquid and more difficult to value than common stock.

Roundhill PLTR WeeklyPay™ ETF | DERIVATIVES RISK  
Prospectus [Line Items]  
Risk [Text Block]

DERIVATIVES RISK. The use of derivative instruments involves risks different from, or possibly greater than, the risks associated with investing directly in securities and other traditional investments. These risks include: (i) the risk that the counterparty to a derivative transaction may not fulfill its contractual obligations; (ii) risk of mispricing or improper valuation; and (iii) the risk that changes in the value of the derivative may not correlate perfectly with the underlying asset. Derivative prices are highly volatile and may fluctuate substantially during a short period of time. Such prices are influenced by numerous factors that affect the markets, including, but not limited to: changing supply and demand relationships; government programs and policies; national and international political and economic events, changes in interest rates, inflation and deflation and changes in supply and demand relationships. Trading derivative instruments involves risks different from, or possibly greater than, the risks associated with investing directly in securities. Derivative contracts ordinarily have leverage inherent in their terms. The use of leverage may cause the Fund to liquidate portfolio positions when it would not be advantageous to do so in order to satisfy its obligations or to meet regulatory or contractual requirements for derivatives. The use of derivatives can magnify potential for gain or loss and, therefore, amplify the effects of market volatility on share price.

Roundhill PLTR WeeklyPay™ ETF | DISTRIBUTION TAX RISK  
Prospectus [Line Items]  
Risk [Text Block]

DISTRIBUTION TAX RISK. The Fund currently expects to make distributions on a weekly basis. Such frequent distributions may expose investors to increased tax liabilities. However, these distributions may exceed the Fund’s income and gains for the Fund’s taxable year. Distributions in excess of the Fund’s current and accumulated earnings and profits will be treated as a return of capital. A return of capital distribution generally will not be taxable but will reduce the shareholder’s cost basis and will result in a higher capital gain or lower capital loss when those Fund Shares on which the distribution was received are sold. Once a Fund shareholder’s cost basis is reduced to zero, further distributions will be treated as capital gain if the Fund shareholder holds Fund Shares as capital assets. Additionally, any capital returned through distributions will be distributed after payment of Fund fees and expenses. Because a portion of the Fund’s distributions may consist of return of capital, the Fund may not be an appropriate investment for investors who do not want their principal investment in the Fund to decrease over time or who do not wish to receive return of capital in a given period. In the event that a shareholder purchases Fund Shares shortly before a distribution by the Fund, the entire distribution may be taxable to the shareholder even though a portion of the distribution effectively represents a return of the purchase price.

Roundhill PLTR WeeklyPay™ ETF | ETF RISK  
Prospectus [Line Items]  
Risk [Text Block]

ETF RISK. The Fund may invest in ETFs. The value of an ETF held by the Fund will fluctuate over time based on fluctuations in the values of the assets held by the ETF, which may be affected by changes in general economic conditions, expectations for future growth and profits, interest rates and the supply and demand for those assets. When the Fund invests in an ETF, it will bear a proportionate share of the ETF’s expenses. Brokerage, tax and other expenses may negatively impact the performance of the ETF and, in turn, the value of the Fund Shares. An ETF that tracks an index may not exactly match the performance of the index due to cash drag, differences between the portfolio of the ETF and the components of the index, expenses and other factors.

Roundhill PLTR WeeklyPay™ ETF | INFLATION RISK  
Prospectus [Line Items]  
Risk [Text Block]

INFLATION RISK. Inflation risk is the risk that the value of assets or income from investments will be less in the future as inflation decreases the value of money. As inflation increases, the present value of the Fund’s assets and distributions may decline. This risk is more prevalent with respect to fixed income securities held by the Fund.

Roundhill PLTR WeeklyPay™ ETF | Interest Rate Risk [Member]  
Prospectus [Line Items]  
Risk [Text Block]

INTEREST RATE RISK. Interest rate risk is the risk that the value of the debt securities in the Fund’s portfolio will decline because of rising market interest rates. Interest rate risk is generally lower for shorter term debt securities and higher for longer-term debt securities. Duration is a reasonably accurate measure of a debt security’s price sensitivity to changes in interest rates and a common measure of interest rate risk. Duration measures a debt security’s expected life on a present value basis, taking into account the debt security’s yield, interest payments and final maturity. In general, duration represents the expected percentage change in the value of a security for an immediate 1% change in interest rates. For example, the price of a debt security with a three-year duration would be expected to drop by approximately 3% in response to a 1% increase in interest rates. Therefore, prices of debt securities with shorter durations tend to be less sensitive to interest rate changes than debt securities with longer durations. As the value of a debt security changes over time, so will its duration.

Roundhill PLTR WeeklyPay™ ETF | LEGISLATION AND LITIGATION RISK  
Prospectus [Line Items]  
Risk [Text Block]

LEGISLATION AND LITIGATION RISK. Legislation or litigation that affects the value of assets or securities held by the Fund may reduce the value of the Fund. From time to time, various legislative initiatives are proposed that may have a negative impact on certain assets or securities in which the Fund invests. In addition, litigation regarding any of the assets or securities owned by the Fund may negatively impact the value of the Shares. Such legislation or litigation may cause the Fund to lose value or may result in higher portfolio turnover if the Adviser determines to sell such a holding.

Roundhill PLTR WeeklyPay™ ETF | LEVERAGE RISK  
Prospectus [Line Items]  
Risk [Text Block]

LEVERAGE RISK. The Fund obtains investment exposure in excess of its net assets by utilizing leverage and may lose more money in market conditions that are adverse to its investment objectives than a fund that does not utilize leverage. An investment in the Fund is exposed to the risk that a decline in the weekly performance of shares of PLTR will be magnified. This means that an investment in the Fund will be reduced by an amount equal to 1.2% for every 1% weekly decline in the market value of the PLTR shares, not including the costs of financing leverage and other operating expenses, which would further reduce its value. The Fund could theoretically lose an amount greater than its net assets in the event the market value of PLTR shares decline more than 83.33% over a calendar week. Leverage will also have the effect of magnifying any differences in the Fund’s correlation with PLTR shares.

Roundhill PLTR WeeklyPay™ ETF | MONEY MARKET INSTRUMENTS RISK  
Prospectus [Line Items]  
Risk [Text Block]

MONEY MARKET INSTRUMENTS RISK. The value of money market instruments may be affected by changing interest rates and by changes in the credit ratings of the investments. If a significant amount of the Fund’s assets are invested in money market instruments, it will be more difficult for the Fund to achieve its investment objectives. An investment in a money market fund is not insured or guaranteed by the FDIC or any other government agency. It is possible to lose money by investing in a money market fund.

Roundhill PLTR WeeklyPay™ ETF | OPERATIONAL RISK  
Prospectus [Line Items]  
Risk [Text Block]

OPERATIONAL RISK. The Fund is subject to risks arising from various operational factors, including, but not limited to, human error, processing and communication errors, errors of the Fund’s service providers, counterparties or other third-parties, failed or inadequate processes and technology or systems failures. The Fund relies on third-parties for a range of services, including custody. Any delay or failure relating to engaging or maintaining such service providers may affect the Fund’s ability to meet its investment objectives. Although the Fund and the Adviser seek to reduce these operational risks through controls and procedures, there is no way to completely protect against such risks.

Roundhill PLTR WeeklyPay™ ETF | SPECIAL TAX RISK  
Prospectus [Line Items]  
Risk [Text Block]

SPECIAL TAX RISK. The Fund intends to qualify annually and to elect to be treated as a regulated investment company under the Internal Revenue Code of 1986, as amended (the “Code”). To qualify for the favorable U.S. federal income tax treatment generally accorded to regulated investment companies, the Fund must, among other things, (i) derive in each taxable year at least 90% of its gross income from dividends, interest, payments with respect to securities loans and gains from the sale or other disposition of stock, securities or foreign currencies or other income derived with respect to its business of investing in such stock, securities or currencies, or net income derived from interests in certain publicly traded partnerships; (ii) diversify its holdings so that, at the end of each quarter of the taxable year, (a) at least 50% of the market value of the Fund’s assets is represented by cash and cash items (including receivables), U.S. government securities, the securities of other regulated investment companies and other securities, with such other securities of any one issuer generally limited for the purposes of this calculation to an amount not greater than 5% of the value of the Fund’s total assets and not greater than 10% of the outstanding voting securities of such issuer, and (b) not more than 25% of the value of its total assets is invested in the securities (other than U.S. government securities or the securities of other regulated investment companies) of any one issuer, or two or more issuers which the Fund controls which are engaged in the same, similar or related trades or businesses, or the securities of one or more of certain publicly traded partnerships; and (iii) distribute at least 90% of its investment company taxable income (which includes, among other items, dividends, interest and net short-term capital gains in excess of net long-term capital losses) and at least 90% of its net tax-exempt interest income each taxable year. There are certain exceptions for failure to qualify if the failure is for reasonable cause or is de minimis, and certain corrective action is taken and certain tax payments are made by the Fund.

 

The authority with regard to swaps entered into by regulated investment companies is unclear both as to the qualification under the income test and the identification of the issuer under the diversification test. The Fund intends to take the position that because the swaps held by the Fund reference securities that the income on the swaps are “other income” from the Fund’s business of investing in stocks and securities. In addition, the Fund intends to manage its investments in the swaps so that neither the exposure to issuer of the referenced security nor the exposure to any one counterparty of the swaps will exceed 25% of the gross value of the Fund’s portfolio at the end of any quarter.

 

If the Fund were to fail to meet the qualifying income test or asset diversification test and fail to qualify as a RIC, it would be taxed in the same manner as an ordinary corporation, and distributions to its shareholders would not be deductible by the Fund in computing its taxable income, which would adversely affect the Fund’s performance.

Roundhill PLTR WeeklyPay™ ETF | STRUCTURAL ETF RISKS  
Prospectus [Line Items]  
Risk [Text Block]

STRUCTURAL ETF RISKS. The Fund is an ETF. Accordingly, it is subject to certain risks associated with its unique structure.

 

Market Participants Risk. Only an Authorized Participant may engage in creation or redemption transactions directly with the Fund, and none of those Authorized Participants is obligated to engage in creation and/or redemption transactions. The Fund has a limited number of institutions that may act as Authorized Participants on an agency basis (i.e., on behalf of other market participants). To the extent that Authorized Participants exit the business or are unable to proceed with creation or redemption orders with respect to the Fund and no other Authorized Participant is able to step forward to create or redeem, Fund Shares may be more likely to trade at a premium or discount to NAV and possibly face trading halts or delisting. The Fund may also rely on a small number of third-party market makers to provide a market for the purchase and sale of Fund Shares but such market makers are under no obligation to do so. Decisions by Authorized Participants or market makers to reduce their role or step away from these activities in times of market stress could inhibit the effectiveness of the arbitrage process in maintaining the relationship between the underlying values of the Fund’s portfolio securities and the Fund’s market price. Any trading halt or other problem relating to the trading activity of these market makers or any issues disrupting the Authorized Participants’ ability to proceed with creation and/or redemption orders could result in a dramatic change in the spread between the Fund’s net asset value and the price at which Fund Shares are trading on the Exchange, which could result in a decrease in value of Fund Shares. This reduced effectiveness could result in Fund Shares trading at a premium or discount to net asset value and also in greater than normal intraday bid-ask spreads Fund Shares.

 

Cash Transactions Risk. The Fund currently expects to effect a significant portion of its creations and redemptions for cash, rather than in-kind securities. Paying redemption proceeds in cash rather than through in-kind delivery of portfolio securities may require the Fund to dispose of or sell portfolio securities or other assets at an inopportune time to obtain the cash needed to meet redemption orders. This may cause the Fund to sell a security and recognize a capital gain or loss that might not have been incurred if it had made a redemption in-kind. As a result, the Fund may pay out higher or lower annual capital gains distributions than ETFs that redeem in-kind. The use of cash creations and redemptions may also cause the Fund’s Shares to trade in the market at greater bid-ask spreads or greater premiums or discounts to the Fund’s net asset value (“NAV”). Furthermore, the Fund may not be able to execute cash transactions for creation and redemption purposes at the same price used to determine the Fund’s NAV. To the extent that the maximum additional charge for creation or redemption transactions is insufficient to cover the execution shortfall, the Fund’s performance could be negatively impacted.

 

Costs of Buying and Selling Fund Shares. Due to the costs of buying or selling Fund Shares, including brokerage commissions imposed by brokers and bid/ask spreads, frequent trading of Fund Shares may significantly reduce investment results and an investment in Fund Shares may not be advisable for investors who anticipate regularly making small investments.

 

Premium/Discount Risk. As with all ETFs, Fund Shares may be bought and sold in the secondary market at market prices. The trading prices of Fund Shares in the secondary market may differ from the Fund’s daily NAV per Fund Share and there may be times when the market price of the Fund Shares is more than the NAV per Fund Share (premium) or less than the NAV per Fund Share (discount). If a shareholder purchases Fund Shares at a time when the market price is at a premium to the NAV or sells Fund Shares at a time when the market price is at a discount to the NAV, the shareholder may pay more for, or receive less than, the underlying value of the Fund Shares, respectively. This risk is heightened in times of market volatility or periods of steep market declines.

 

Trading Risks. Although Fund Shares are listed for trading on the Exchange and may be traded on U.S. exchanges other than the Exchange, there can be no assurance that Fund Shares will trade with any volume, or at all, on any stock exchange. In stressed market conditions, the liquidity of Fund Shares may begin to mirror the liquidity of the Fund’s underlying portfolio holdings, which can be significantly less liquid than Fund Shares. Trading in Fund Shares on the Exchange may be halted due to market conditions or for reasons that, in the view of the Exchange, make trading in Fund Shares inadvisable. In addition, trading in Fund Shares on the Exchange is subject to trading halts caused by extraordinary market volatility pursuant to the Exchange’s “circuit breaker” rules. There can be no assurance that the requirements of the Exchange necessary to maintain the listing of the Fund will continue to be met or will remain unchanged.

Roundhill PLTR WeeklyPay™ ETF | U.S. GOVERNMENT SECURITIES RISK  
Prospectus [Line Items]  
Risk [Text Block]

U.S. GOVERNMENT SECURITIES RISK. U.S. government securities are subject to interest rate risk but generally do not involve the credit risks associated with investments in other types of debt securities. As a result, the yields available from U.S. government securities are generally lower than the yields available from other debt securities. U.S. government securities are guaranteed only as to the timely payment of interest and the payment of principal when held to maturity.

Roundhill PLTR WeeklyPay™ ETF | VALUATION RISK  
Prospectus [Line Items]  
Risk [Text Block]

VALUATION RISK. The Fund may hold securities or other assets that may be valued on the basis of factors other than market quotations. This may occur because the asset or security does not trade on a centralized exchange, or in times of market turmoil or reduced liquidity. There are multiple methods that can be used to value a portfolio holding when market quotations are not readily available. The value established for any portfolio holding at a point in time might differ from what would be produced using a different methodology or if it had been priced using market quotations. Portfolio holdings that are valued using techniques other than market quotations, including “fair valued” assets or securities, may be subject to greater fluctuation in their valuations from one day to the next than if market quotations were used. In addition, there is no assurance that the Fund could sell or close out a portfolio position for the value established for it at any time, and it is possible that the Fund would incur a loss because a portfolio position is sold or closed out at a discount to the valuation established by the Fund at that time. The Fund’s ability to value investments may be impacted by technological issues or errors by pricing services or other third-party service providers.

Roundhill PLTR WeeklyPay™ ETF | EQUITY SECURITIES RISK  
Prospectus [Line Items]  
Risk [Text Block]

EQUITY SECURITIES RISK. Equity securities are subject to changes in value, and their values may be more volatile than those of other asset classes. Equity securities prices fluctuate for several reasons, including changes in investors’ perceptions of the financial condition of an issuer or the general condition of the relevant equity market, such as market volatility, or when political or economic events affecting an issuer occur. Common stock prices may be particularly sensitive to rising interest rates, as the cost of capital rises and borrowing costs increase. Common stocks generally subject their holders to more risks than preferred stocks and debt securities because common stockholders’ claims are subordinated to those of holders of preferred stocks and debt securities upon the bankruptcy of the issuer.

Roundhill PLTR WeeklyPay™ ETF | SWAP AGREEMENTS RISK  
Prospectus [Line Items]  
Risk [Text Block]

SWAP AGREEMENTS RISK. The Fund will utilize swap agreements to derive its exposure to shares of PLTR. Swap agreements may involve greater risks than direct investment in securities as they may be leveraged and are subject to credit risk, counterparty risk and valuation risk. A swap agreement could result in losses if the underlying reference or asset does not perform as anticipated. In addition, many swaps trade over-the-counter and may be considered illiquid. It may not be possible for the Fund to liquidate a swap position at an advantageous time or price, which may result in significant losses.

Roundhill PLTR WeeklyPay™ ETF | REGULATED INVESTMENT COMPANY TAX RISKS  
Prospectus [Line Items]  
Risk [Text Block]

REGULATED INVESTMENT COMPANY TAX RISKS. The Fund intends to qualify annually and to elect to be treated as a regulated investment company under the Internal Revenue Code of 1986, as amended (the “Code”). To qualify for the favorable U.S. federal income tax treatment generally accorded to regulated investment companies, the Fund must, among other things, (i) derive in each taxable year at least 90% of its gross income from dividends, interest, payments with respect to securities loans and gains from the sale or other disposition of stock, securities or foreign currencies or other income derived with respect to its business of investing in such stock, securities or currencies, or net income derived from interests in certain publicly traded partnerships; (ii) diversify its holdings so that, at the end of each quarter of the taxable year, (a) at least 50% of the market value of the Fund’s assets is represented by cash and cash items (including receivables), U.S. government securities, the securities of other regulated investment companies and other securities, with such other securities of any one issuer generally limited for the purposes of this calculation to an amount not greater than 5% of the value of the Fund’s total assets and not greater than 10% of the outstanding voting securities of such issuer, and (b) not more than 25% of the value of its total assets is invested in the securities (other than U.S. government securities or the securities of other regulated investment companies) of any one issuer, or two or more issuers which the Fund controls which are engaged in the same, similar or related trades or businesses, or the securities of one or more of certain publicly traded partnerships; and (iii) distribute at least 90% of its investment company taxable income (which includes, among other items, dividends, interest and net short-term capital gains in excess of net long-term capital losses) and at least 90% of its net tax-exempt interest income each taxable year. There are certain exceptions for failure to qualify if the failure is for reasonable cause or is de minimis, and certain corrective action is taken and certain tax payments are made by the Fund.

 

If the Fund were to fail to meet the qualifying income test or asset diversification test and fail to qualify as a RIC, it would be taxed in the same manner as an ordinary corporation, and distributions to its shareholders would not be deductible by the Fund in computing its taxable income, which would adversely affect the Fund’s performance.

Roundhill PLTR WeeklyPay™ ETF | LARGE SHAREHOLDER RISK  
Prospectus [Line Items]  
Risk [Text Block]

LARGE SHAREHOLDER RISK. Certain shareholders, including affiliated funds advised by the Adviser, may from time to time own a significant portion of the Fund’s shares. In addition, a third-party investor, the Adviser or an affiliate of the Adviser (“Affiliate”), an authorized participant, a market maker, or another entity may invest in the Fund and hold its investment for a limited period solely to facilitate the commencement of the Fund or to help the Fund achieve a specified size or scale. There can be no assurance that any large shareholder will not redeem its investment, that the size of the Fund will be maintained at such levels, or that the Fund will continue to meet applicable listing requirements. Redemptions by large shareholders could have a significant negative impact on the Fund. In addition, transactions by large shareholders may account for a large percentage of the trading volume on the Fund’s listing exchange and may, therefore, have a material upward or downward effect on the market price of the shares.

 

To the extent that a significant percentage of the Fund’s shares are owned or controlled by a small number of account shareholders (or a single account shareholder), including funds or accounts over which the Adviser or an Affiliate has investment discretion, the Fund is subject to the risk that those shareholders may purchase or redeem Fund shares in significant amounts rapidly or unexpectedly, including as a result of an asset allocation decision made by the Adviser or an Affiliate. This may adversely affect the Fund’s performance if the Adviser is forced to sell portfolio securities or invest cash when it would not otherwise choose to do so. Redemptions of a large number of shares may affect the liquidity of the Fund’s portfolio, increase the Fund’s transaction costs, and accelerate the realization of taxable income and/or gains. In addition, a large redemption could result in the Fund’s current expenses being allocated over a smaller asset base, leading to an increase in the Fund’s gross expense ratio. Large purchases of the Fund’s shares may also adversely affect the Fund’s performance to the extent that the Fund is delayed in investing new cash or otherwise maintains a larger cash position than it ordinarily would, particularly if the Fund accepts cash for an order for the purchase of creation units of the Fund’s shares.

Roundhill PLTR WeeklyPay™ ETF | PLTR INVESTING RISKS  
Prospectus [Line Items]  
Risk [Text Block]

PLTR INVESTING RISKS. The Fund will have significant exposure to PLTR through its investments in swap agreements that utilize PLTR as the reference asset. Accordingly, the Fund will subject to the risks of PLTR, set forth below.

 

PLTR ISSUER-SPECIFIC RISKS. Issuer-specific attributes may cause an investment held by the Fund to be more volatile than the market generally. The value of an individual security or particular type of security may be more volatile than the market as a whole and may perform differently from the value of the market as a whole. As of the date of this prospectus, in addition to the risks associated with companies in the information technology sector, Palantir Technologies Inc. faces risks associated with: reliance on government contracts, competitive industry dynamics, regulatory and geopolitical risks, technological and cybersecurity challenges and revenue concentration. A significant portion of PLTR revenue is derived from government contracts, which are subject to termination, non-renewal, or reductions in funding due to budgetary constraints or political decisions. Changes in government priorities or the loss of key contracts could adversely affect its business. PLTR also operates in a highly competitive and rapidly evolving industry. The company faces competition from established technology companies, as well as emerging startups offering innovative solutions. Failure to maintain its competitive edge could result in reduced market share and profitability. PLTR’s operations, particularly its involvement with government and defense agencies, expose it to regulatory scrutiny and geopolitical risks. Changes in data privacy laws, export controls, or international relations could impact its ability to conduct business effectively. PLTR’s business depends on its ability to provide secure, reliable, and advanced software solutions. Any failure to address cybersecurity vulnerabilities, system outages or technology obsolescence could harm its reputation and client trust, resulting in financial losses. PLTR derives a substantial portion of its revenue from a limited number of clients. This concentration risk makes the company vulnerable to changes in spending patterns or contract renewals from a small set of customers.

 

INDIRECT INVESTMENT RISK. Microsoft Corporation is not affiliated with the Trust, the Fund, the Adviser, the Sub-Adviser or any affiliates thereof and is not involved with this offering in any way, and has no obligation to consider the Fund in taking any corporate actions that might affect the value of the Fund. The Trust, the Fund, the Adviser, the Sub-Adviser or any affiliate are not responsible for the performance of PLTR and make no representation as to the performance of PLTR. Investing in the Fund is not equivalent to investing in PLTR. Fund shareholders will not have voting rights or rights to receive dividends or other distributions or any other rights with respect to PLTR.

 

INFORMATION TECHNOLOGY COMPANIES RISK. Information technology companies face intense competition, both domestically and internationally, which may have an adverse effect on profit margins. Like other technology companies, information technology companies may have limited product lines, markets, financial resources or personnel. The products of information technology companies may face obsolescence due to rapid technological developments, frequent new product introduction, unpredictable changes in growth rates and competition for the services of qualified personnel. Companies in the information technology sector are heavily dependent on patent and intellectual property rights. The loss or impairment of these rights may adversely affect the profitability of these companies. Information technology companies are facing increased government and regulatory scrutiny and may be subject to adverse government or regulatory action.

 

LARGE CAPITALIZATION COMPANIES RISK. Large capitalization companies may be less able than smaller capitalization companies to adapt to changing market conditions. Large capitalization companies may be more mature and subject to more limited growth potential compared with smaller capitalization companies. During different market cycles, the performance of large capitalization companies has trailed the overall performance of the broader securities markets.

 

UNITED STATES RISK. Certain changes in the U.S. economy, such as when the U.S. economy weakens or when its financial markets decline, may have an adverse effect on the securities to which the Fund has exposure.

NON-DIVERSIFICATION RISK. As a “non-diversified” fund, the Fund may hold a smaller number of portfolio securities than many other funds. To the extent the Fund invests in a relatively small number of issuers, a decline in the market value of a particular security held by the Fund may affect its value more than if it invested in a larger number of issuers. The value of the Fund Shares may be more volatile than the values of shares of more diversified funds.

MARKET RISK. Market risk is the risk that a particular investment, or Fund Shares in general, may fall in value. Securities are subject to market fluctuations caused by real or perceived adverse economic, political, and regulatory factors or market developments, changes in interest rates, disruptions to trade, impositions of tariffs and perceived trends in securities prices. Fund Shares could decline in value or underperform other investments. In addition, local, regional or global events such as war, acts of terrorism, market manipulation, government defaults, government shutdowns, regulatory actions, political changes, diplomatic developments, the imposition of sanctions and other similar measures, spread of infectious diseases or other public health issues, recessions, natural disasters, or other events could have a significant negative impact on the Fund and its investments. Any of such circumstances could have a materially negative impact on the value of Fund Shares, the liquidity of an investment, and may result in increased market volatility. During any such events, Fund Shares may trade at increased premiums or discounts to their net asset value, the bid/ask spread on Fund Shares may widen and the returns on investment may fluctuate.

Roundhill NVDA WeeklyPay™ ETF | LIQUIDITY RISK

Risk [Text Block]

LIQUIDITY RISK. The market for swap agreements that reference NVDA shares may be subject to periods of illiquidity. During such times it may be difficult or impossible to buy or sell a position at the desired price. Market disruptions or volatility can also make it difficult to find a counterparty willing to transact at a reasonable price and sufficient size. Illiquid markets may cause losses, which could be significant. The large size of the positions which the Fund may acquire increases the risk of illiquidity, may make its positions more difficult to liquidate, and may increase the losses incurred while trying to do so. Such large positions also may impact the price of swap agreements on NVDA shares.

Roundhill NVDA WeeklyPay™ ETF | ACTIVE MANAGEMENT RISK  
Prospectus [Line Items]  
Risk [Text Block]

ACTIVE MANAGEMENT RISK. The Fund is actively-managed and its performance reflects investment decisions that the Adviser and/or Sub-Adviser makes for the Fund. Such judgments about the Fund’s investments may prove to be incorrect. If the investments selected and the strategies employed by the Fund fail to produce the intended results, the Fund could underperform as compared to other funds with similar investment objectives and/or strategies, or could have negative returns.

Roundhill NVDA WeeklyPay™ ETF | ACTIVE MARKET RISK  
Prospectus [Line Items]  
Risk [Text Block]

ACTIVE MARKET RISK. Although Fund Shares are listed for trading on the Exchange, there can be no assurance that an active trading market for Fund Shares will develop or be maintained. Fund Shares trade on the Exchange at market prices that may be below, at or above the Fund’s net asset value. Securities, including Fund Shares, are subject to market fluctuations and liquidity constraints that may be caused by such factors as economic, political, or regulatory developments, changes in interest rates, and/or perceived trends in securities prices. Fund Shares could decline in value or underperform other investments.

Risk [Text Block]

CONCENTRATION RISK. The Fund is susceptible to an increased risk of loss, including losses due to adverse events that affect the Fund’s investments more than the market as a whole, to the extent that the Fund’s investments are concentrated in investments that provide exposure to NVDA and the industry to which it is assigned.

Roundhill NVDA WeeklyPay™ ETF | COUNTERPARTY RISK  
Prospectus [Line Items]  
Risk [Text Block]

COUNTERPARTY RISK. Fund transactions involving a counterparty are subject to the risk that the counterparty will not fulfill its obligation to the Fund. Counterparty risk may arise because of the counterparty’s financial condition (i.e., financial difficulties, bankruptcy, or insolvency), market activities and developments, or other reasons, whether foreseen or not. A counterparty’s inability to fulfill its obligation may result in significant financial loss to the Fund. The Fund may be unable to recover its investment from the counterparty or may obtain a limited recovery, and/or recovery may be delayed.

CREDIT RISK. An issuer or other obligated party of a debt security may be unable or unwilling to make dividend, interest and/or principal payments when due. In addition, the value of a debt security may decline because of concerns about the issuer’s ability or unwillingness to make such payments.

Roundhill NVDA WeeklyPay™ ETF | CYBERSECURITY RISK  
Prospectus [Line Items]  
Risk [Text Block]

CYBERSECURITY RISK. Failures or breaches of the electronic systems of the Fund, the Fund’s adviser, sub-adviser, distributor and other service providers, market makers, Authorized Participants or the issuers of securities in which the Fund invests have the ability to cause disruptions, negatively impact the Fund’s business operations and/or potentially result in financial losses to the Fund and its shareholders. While the Fund has established business continuity plans and risk management systems seeking to address system breaches or failures, there are inherent limitations in such plans and systems. Furthermore, the Fund cannot control the cybersecurity plans and systems of the Fund’s other service providers, market makers, Authorized Participants or issuers of securities in which the Fund invests.

Roundhill NVDA WeeklyPay™ ETF | DEBT SECURITIES RISK  
Prospectus [Line Items]  
Risk [Text Block]

DEBT SECURITIES RISK. Investments in debt securities subject the holder to the credit risk of the issuer. Credit risk refers to the possibility that the issuer or other obligor of a security will not be able or willing to make payments of interest and principal when due. Generally, the value of debt securities will change inversely with changes in interest rates. To the extent that interest rates rise, certain underlying obligations may be paid off substantially slower than originally anticipated and the value of those securities may fall sharply. During periods of falling interest rates, the income received by the Fund may decline. If the principal on a debt security is prepaid before expected, the prepayments of principal may have to be reinvested in obligations paying interest at lower rates. Debt securities generally do not trade on a securities exchange making them generally less liquid and more difficult to value than common stock.

Roundhill NVDA WeeklyPay™ ETF | DERIVATIVES RISK  
Prospectus [Line Items]  
Risk [Text Block]

DERIVATIVES RISK. The use of derivative instruments involves risks different from, or possibly greater than, the risks associated with investing directly in securities and other traditional investments. These risks include: (i) the risk that the counterparty to a derivative transaction may not fulfill its contractual obligations; (ii) risk of mispricing or improper valuation; and (iii) the risk that changes in the value of the derivative may not correlate perfectly with the underlying asset. Derivative prices are highly volatile and may fluctuate substantially during a short period of time. Such prices are influenced by numerous factors that affect the markets, including, but not limited to: changing supply and demand relationships; government programs and policies; national and international political and economic events, changes in interest rates, inflation and deflation and changes in supply and demand relationships. Trading derivative instruments involves risks different from, or possibly greater than, the risks associated with investing directly in securities. Derivative contracts ordinarily have leverage inherent in their terms. The use of leverage may cause the Fund to liquidate portfolio positions when it would not be advantageous to do so in order to satisfy its obligations or to meet regulatory or contractual requirements for derivatives. The use of derivatives can magnify potential for gain or loss and, therefore, amplify the effects of market volatility on share price.

Roundhill NVDA WeeklyPay™ ETF | DISTRIBUTION TAX RISK  
Prospectus [Line Items]  
Risk [Text Block]

DISTRIBUTION TAX RISK. The Fund currently expects to make distributions on a weekly basis. Such frequent distributions may expose investors to increased tax liabilities. However, these distributions may exceed the Fund’s income and gains for the Fund’s taxable year. Distributions in excess of the Fund’s current and accumulated earnings and profits will be treated as a return of capital. A return of capital distribution generally will not be taxable but will reduce the shareholder’s cost basis and will result in a higher capital gain or lower capital loss when those Fund Shares on which the distribution was received are sold. Once a Fund shareholder’s cost basis is reduced to zero, further distributions will be treated as capital gain if the Fund shareholder holds Fund Shares as capital assets. Additionally, any capital returned through distributions will be distributed after payment of Fund fees and expenses. Because a portion of the Fund’s distributions may consist of return of capital, the Fund may not be an appropriate investment for investors who do not want their principal investment in the Fund to decrease over time or who do not wish to receive return of capital in a given period. In the event that a shareholder purchases Fund Shares shortly before a distribution by the Fund, the entire distribution may be taxable to the shareholder even though a portion of the distribution effectively represents a return of the purchase price.

Roundhill NVDA WeeklyPay™ ETF | ETF RISK  
Prospectus [Line Items]  
Risk [Text Block]

ETF RISK. The Fund may invest in ETFs. The value of an ETF held by the Fund will fluctuate over time based on fluctuations in the values of the assets held by the ETF, which may be affected by changes in general economic conditions, expectations for future growth and profits, interest rates and the supply and demand for those assets. When the Fund invests in an ETF, it will bear a proportionate share of the ETF’s expenses. Brokerage, tax and other expenses may negatively impact the performance of the ETF and, in turn, the value of the Fund Shares. An ETF that tracks an index may not exactly match the performance of the index due to cash drag, differences between the portfolio of the ETF and the components of the index, expenses and other factors.

Roundhill NVDA WeeklyPay™ ETF | INFLATION RISK  
Prospectus [Line Items]  
Risk [Text Block]

INFLATION RISK. Inflation risk is the risk that the value of assets or income from investments will be less in the future as inflation decreases the value of money. As inflation increases, the present value of the Fund’s assets and distributions may decline. This risk is more prevalent with respect to fixed income securities held by the Fund.

Roundhill NVDA WeeklyPay™ ETF | Interest Rate Risk [Member]  
Prospectus [Line Items]  
Risk [Text Block]

INTEREST RATE RISK. Interest rate risk is the risk that the value of the debt securities in the Fund’s portfolio will decline because of rising market interest rates. Interest rate risk is generally lower for shorter term debt securities and higher for longer-term debt securities. Duration is a reasonably accurate measure of a debt security’s price sensitivity to changes in interest rates and a common measure of interest rate risk. Duration measures a debt security’s expected life on a present value basis, taking into account the debt security’s yield, interest payments and final maturity. In general, duration represents the expected percentage change in the value of a security for an immediate 1% change in interest rates. For example, the price of a debt security with a three-year duration would be expected to drop by approximately 3% in response to a 1% increase in interest rates. Therefore, prices of debt securities with shorter durations tend to be less sensitive to interest rate changes than debt securities with longer durations. As the value of a debt security changes over time, so will its duration.

Roundhill NVDA WeeklyPay™ ETF | LEGISLATION AND LITIGATION RISK  
Prospectus [Line Items]  
Risk [Text Block]

LEGISLATION AND LITIGATION RISK. Legislation or litigation that affects the value of assets or securities held by the Fund may reduce the value of the Fund. From time to time, various legislative initiatives are proposed that may have a negative impact on certain assets or securities in which the Fund invests. In addition, litigation regarding any of the assets or securities owned by the Fund may negatively impact the value of the Shares. Such legislation or litigation may cause the Fund to lose value or may result in higher portfolio turnover if the Adviser determines to sell such a holding.

Roundhill NVDA WeeklyPay™ ETF | LEVERAGE RISK  
Prospectus [Line Items]  
Risk [Text Block]

LEVERAGE RISK. The Fund obtains investment exposure in excess of its net assets by utilizing leverage and may lose more money in market conditions that are adverse to its investment objectives than a fund that does not utilize leverage. An investment in the Fund is exposed to the risk that a decline in the weekly performance of shares of NVDA will be magnified. This means that an investment in the Fund will be reduced by an amount equal to 1.2% for every 1% weekly decline in the market value of the NVDA shares, not including the costs of financing leverage and other operating expenses, which would further reduce its value. The Fund could theoretically lose an amount greater than its net assets in the event the market value of NVDA shares decline more than 83.33% over a calendar week. Leverage will also have the effect of magnifying any differences in the Fund’s correlation with NVDA shares.

Roundhill NVDA WeeklyPay™ ETF | MONEY MARKET INSTRUMENTS RISK  
Prospectus [Line Items]  
Risk [Text Block]

MONEY MARKET INSTRUMENTS RISK. The value of money market instruments may be affected by changing interest rates and by changes in the credit ratings of the investments. If a significant amount of the Fund’s assets are invested in money market instruments, it will be more difficult for the Fund to achieve its investment objectives. An investment in a money market fund is not insured or guaranteed by the FDIC or any other government agency. It is possible to lose money by investing in a money market fund.

Roundhill NVDA WeeklyPay™ ETF | OPERATIONAL RISK  
Prospectus [Line Items]  
Risk [Text Block]

OPERATIONAL RISK. The Fund is subject to risks arising from various operational factors, including, but not limited to, human error, processing and communication errors, errors of the Fund’s service providers, counterparties or other third-parties, failed or inadequate processes and technology or systems failures. The Fund relies on third-parties for a range of services, including custody. Any delay or failure relating to engaging or maintaining such service providers may affect the Fund’s ability to meet its investment objectives. Although the Fund and the Adviser seek to reduce these operational risks through controls and procedures, there is no way to completely protect against such risks.

Roundhill NVDA WeeklyPay™ ETF | SPECIAL TAX RISK  
Prospectus [Line Items]  
Risk [Text Block]

SPECIAL TAX RISK. The Fund intends to qualify annually and to elect to be treated as a regulated investment company under the Internal Revenue Code of 1986, as amended (the “Code”). To qualify for the favorable U.S. federal income tax treatment generally accorded to regulated investment companies, the Fund must, among other things, (i) derive in each taxable year at least 90% of its gross income from dividends, interest, payments with respect to securities loans and gains from the sale or other disposition of stock, securities or foreign currencies or other income derived with respect to its business of investing in such stock, securities or currencies, or net income derived from interests in certain publicly traded partnerships; (ii) diversify its holdings so that, at the end of each quarter of the taxable year, (a) at least 50% of the market value of the Fund’s assets is represented by cash and cash items (including receivables), U.S. government securities, the securities of other regulated investment companies and other securities, with such other securities of any one issuer generally limited for the purposes of this calculation to an amount not greater than 5% of the value of the Fund’s total assets and not greater than 10% of the outstanding voting securities of such issuer, and (b) not more than 25% of the value of its total assets is invested in the securities (other than U.S. government securities or the securities of other regulated investment companies) of any one issuer, or two or more issuers which the Fund controls which are engaged in the same, similar or related trades or businesses, or the securities of one or more of certain publicly traded partnerships; and (iii) distribute at least 90% of its investment company taxable income (which includes, among other items, dividends, interest and net short-term capital gains in excess of net long-term capital losses) and at least 90% of its net tax-exempt interest income each taxable year. There are certain exceptions for failure to qualify if the failure is for reasonable cause or is de minimis, and certain corrective action is taken and certain tax payments are made by the Fund.

 

The authority with regard to swaps entered into by regulated investment companies is unclear both as to the qualification under the income test and the identification of the issuer under the diversification test. The Fund intends to take the position that because the swaps held by the Fund reference securities that the income on the swaps are “other income” from the Fund’s business of investing in stocks and securities. In addition, the Fund intends to manage its investments in the swaps so that neither the exposure to issuer of the referenced security nor the exposure to any one counterparty of the swaps will exceed 25% of the gross value of the Fund’s portfolio at the end of any quarter.

 

If the Fund were to fail to meet the qualifying income test or asset diversification test and fail to qualify as a RIC, it would be taxed in the same manner as an ordinary corporation, and distributions to its shareholders would not be deductible by the Fund in computing its taxable income, which would adversely affect the Fund’s performance.

Roundhill NVDA WeeklyPay™ ETF | STRUCTURAL ETF RISKS  
Prospectus [Line Items]  
Risk [Text Block]

STRUCTURAL ETF RISKS. The Fund is an ETF. Accordingly, it is subject to certain risks associated with its unique structure.

 

Market Participants Risk. Only an Authorized Participant may engage in creation or redemption transactions directly with the Fund, and none of those Authorized Participants is obligated to engage in creation and/or redemption transactions. The Fund has a limited number of institutions that may act as Authorized Participants on an agency basis (i.e., on behalf of other market participants). To the extent that Authorized Participants exit the business or are unable to proceed with creation or redemption orders with respect to the Fund and no other Authorized Participant is able to step forward to create or redeem, Fund Shares may be more likely to trade at a premium or discount to NAV and possibly face trading halts or delisting. The Fund may also rely on a small number of third-party market makers to provide a market for the purchase and sale of Fund Shares but such market makers are under no obligation to do so. Decisions by Authorized Participants or market makers to reduce their role or step away from these activities in times of market stress could inhibit the effectiveness of the arbitrage process in maintaining the relationship between the underlying values of the Fund’s portfolio securities and the Fund’s market price. Any trading halt or other problem relating to the trading activity of these market makers or any issues disrupting the Authorized Participants’ ability to proceed with creation and/or redemption orders could result in a dramatic change in the spread between the Fund’s net asset value and the price at which Fund Shares are trading on the Exchange, which could result in a decrease in value of Fund Shares. This reduced effectiveness could result in Fund Shares trading at a premium or discount to net asset value and also in greater than normal intraday bid-ask spreads Fund Shares.

 

Cash Transactions Risk. The Fund currently expects to effect a significant portion of its creations and redemptions for cash, rather than in-kind securities. Paying redemption proceeds in cash rather than through in-kind delivery of portfolio securities may require the Fund to dispose of or sell portfolio securities or other assets at an inopportune time to obtain the cash needed to meet redemption orders. This may cause the Fund to sell a security and recognize a capital gain or loss that might not have been incurred if it had made a redemption in-kind. As a result, the Fund may pay out higher or lower annual capital gains distributions than ETFs that redeem in-kind. The use of cash creations and redemptions may also cause the Fund’s Shares to trade in the market at greater bid-ask spreads or greater premiums or discounts to the Fund’s net asset value (“NAV”). Furthermore, the Fund may not be able to execute cash transactions for creation and redemption purposes at the same price used to determine the Fund’s NAV. To the extent that the maximum additional charge for creation or redemption transactions is insufficient to cover the execution shortfall, the Fund’s performance could be negatively impacted.

 

Costs of Buying and Selling Fund Shares. Due to the costs of buying or selling Fund Shares, including brokerage commissions imposed by brokers and bid/ask spreads, frequent trading of Fund Shares may significantly reduce investment results and an investment in Fund Shares may not be advisable for investors who anticipate regularly making small investments.

 

Premium/Discount Risk. As with all ETFs, Fund Shares may be bought and sold in the secondary market at market prices. The trading prices of Fund Shares in the secondary market may differ from the Fund’s daily NAV per Fund Share and there may be times when the market price of the Fund Shares is more than the NAV per Fund Share (premium) or less than the NAV per Fund Share (discount). If a shareholder purchases Fund Shares at a time when the market price is at a premium to the NAV or sells Fund Shares at a time when the market price is at a discount to the NAV, the shareholder may pay more for, or receive less than, the underlying value of the Fund Shares, respectively. This risk is heightened in times of market volatility or periods of steep market declines.

 

Trading Risks. Although Fund Shares are listed for trading on the Exchange and may be traded on U.S. exchanges other than the Exchange, there can be no assurance that Fund Shares will trade with any volume, or at all, on any stock exchange. In stressed market conditions, the liquidity of Fund Shares may begin to mirror the liquidity of the Fund’s underlying portfolio holdings, which can be significantly less liquid than Fund Shares. Trading in Fund Shares on the Exchange may be halted due to market conditions or for reasons that, in the view of the Exchange, make trading in Fund Shares inadvisable. In addition, trading in Fund Shares on the Exchange is subject to trading halts caused by extraordinary market volatility pursuant to the Exchange’s “circuit breaker” rules. There can be no assurance that the requirements of the Exchange necessary to maintain the listing of the Fund will continue to be met or will remain unchanged.

Roundhill NVDA WeeklyPay™ ETF | U.S. GOVERNMENT SECURITIES RISK  
Prospectus [Line Items]  
Risk [Text Block]

U.S. GOVERNMENT SECURITIES RISK. U.S. government securities are subject to interest rate risk but generally do not involve the credit risks associated with investments in other types of debt securities. As a result, the yields available from U.S. government securities are generally lower than the yields available from other debt securities. U.S. government securities are guaranteed only as to the timely payment of interest and the payment of principal when held to maturity.

Roundhill NVDA WeeklyPay™ ETF | VALUATION RISK  
Prospectus [Line Items]  
Risk [Text Block]

VALUATION RISK. The Fund may hold securities or other assets that may be valued on the basis of factors other than market quotations. This may occur because the asset or security does not trade on a centralized exchange, or in times of market turmoil or reduced liquidity. There are multiple methods that can be used to value a portfolio holding when market quotations are not readily available. The value established for any portfolio holding at a point in time might differ from what would be produced using a different methodology or if it had been priced using market quotations. Portfolio holdings that are valued using techniques other than market quotations, including “fair valued” assets or securities, may be subject to greater fluctuation in their valuations from one day to the next than if market quotations were used. In addition, there is no assurance that the Fund could sell or close out a portfolio position for the value established for it at any time, and it is possible that the Fund would incur a loss because a portfolio position is sold or closed out at a discount to the valuation established by the Fund at that time. The Fund’s ability to value investments may be impacted by technological issues or errors by pricing services or other third-party service providers. 

Roundhill NVDA WeeklyPay™ ETF | EQUITY SECURITIES RISK  
Prospectus [Line Items]  
Risk [Text Block]

EQUITY SECURITIES RISK. Equity securities are subject to changes in value, and their values may be more volatile than those of other asset classes. Equity securities prices fluctuate for several reasons, including changes in investors’ perceptions of the financial condition of an issuer or the general condition of the relevant equity market, such as market volatility, or when political or economic events affecting an issuer occur. Common stock prices may be particularly sensitive to rising interest rates, as the cost of capital rises and borrowing costs increase. Common stocks generally subject their holders to more risks than preferred stocks and debt securities because common stockholders’ claims are subordinated to those of holders of preferred stocks and debt securities upon the bankruptcy of the issuer.

Roundhill NVDA WeeklyPay™ ETF | SWAP AGREEMENTS RISK  
Prospectus [Line Items]  
Risk [Text Block]

SWAP AGREEMENTS RISK. The Fund will utilize swap agreements to derive its exposure to shares of NVDA. Swap agreements may involve greater risks than direct investment in securities as they may be leveraged and are subject to credit risk, counterparty risk and valuation risk. A swap agreement could result in losses if the underlying reference or asset does not perform as anticipated. In addition, many swaps trade over-the-counter and may be considered illiquid. It may not be possible for the Fund to liquidate a swap position at an advantageous time or price, which may result in significant losses.

Roundhill NVDA WeeklyPay™ ETF | REGULATED INVESTMENT COMPANY TAX RISKS  
Prospectus [Line Items]  
Risk [Text Block]

REGULATED INVESTMENT COMPANY TAX RISKS. The Fund intends to qualify annually and to elect to be treated as a regulated investment company under the Internal Revenue Code of 1986, as amended (the “Code”). To qualify for the favorable U.S. federal income tax treatment generally accorded to regulated investment companies, the Fund must, among other things, (i) derive in each taxable year at least 90% of its gross income from dividends, interest, payments with respect to securities loans and gains from the sale or other disposition of stock, securities or foreign currencies or other income derived with respect to its business of investing in such stock, securities or currencies, or net income derived from interests in certain publicly traded partnerships; (ii) diversify its holdings so that, at the end of each quarter of the taxable year, (a) at least 50% of the market value of the Fund’s assets is represented by cash and cash items (including receivables), U.S. government securities, the securities of other regulated investment companies and other securities, with such other securities of any one issuer generally limited for the purposes of this calculation to an amount not greater than 5% of the value of the Fund’s total assets and not greater than 10% of the outstanding voting securities of such issuer, and (b) not more than 25% of the value of its total assets is invested in the securities (other than U.S. government securities or the securities of other regulated investment companies) of any one issuer, or two or more issuers which the Fund controls which are engaged in the same, similar or related trades or businesses, or the securities of one or more of certain publicly traded partnerships; and (iii) distribute at least 90% of its investment company taxable income (which includes, among other items, dividends, interest and net short-term capital gains in excess of net long-term capital losses) and at least 90% of its net tax-exempt interest income each taxable year. There are certain exceptions for failure to qualify if the failure is for reasonable cause or is de minimis, and certain corrective action is taken and certain tax payments are made by the Fund.

 

If the Fund were to fail to meet the qualifying income test or asset diversification test and fail to qualify as a RIC, it would be taxed in the same manner as an ordinary corporation, and distributions to its shareholders would not be deductible by the Fund in computing its taxable income, which would adversely affect the Fund’s performance.

Roundhill NVDA WeeklyPay™ ETF | LARGE SHAREHOLDER RISK  
Prospectus [Line Items]  
Risk [Text Block]

LARGE SHAREHOLDER RISK. Certain shareholders, including affiliated funds advised by the Adviser, may from time to time own a significant portion of the Fund’s shares. In addition, a third-party investor, the Adviser or an affiliate of the Adviser (“Affiliate”), an authorized participant, a market maker, or another entity may invest in the Fund and hold its investment for a limited period solely to facilitate the commencement of the Fund or to help the Fund achieve a specified size or scale. There can be no assurance that any large shareholder will not redeem its investment, that the size of the Fund will be maintained at such levels, or that the Fund will continue to meet applicable listing requirements. Redemptions by large shareholders could have a significant negative impact on the Fund. In addition, transactions by large shareholders may account for a large percentage of the trading volume on the Fund’s listing exchange and may, therefore, have a material upward or downward effect on the market price of the shares.

 

To the extent that a significant percentage of the Fund’s shares are owned or controlled by a small number of account shareholders (or a single account shareholder), including funds or accounts over which the Adviser or an Affiliate has investment discretion, the Fund is subject to the risk that those shareholders may purchase or redeem Fund shares in significant amounts rapidly or unexpectedly, including as a result of an asset allocation decision made by the Adviser or an Affiliate. This may adversely affect the Fund’s performance if the Adviser is forced to sell portfolio securities or invest cash when it would not otherwise choose to do so. Redemptions of a large number of shares may affect the liquidity of the Fund’s portfolio, increase the Fund’s transaction costs, and accelerate the realization of taxable income and/or gains. In addition, a large redemption could result in the Fund’s current expenses being allocated over a smaller asset base, leading to an increase in the Fund’s gross expense ratio. Large purchases of the Fund’s shares may also adversely affect the Fund’s performance to the extent that the Fund is delayed in investing new cash or otherwise maintains a larger cash position than it ordinarily would, particularly if the Fund accepts cash for an order for the purchase of creation units of the Fund’s shares.

Roundhill NVDA WeeklyPay™ ETF | NVDA INVESTING RISKS  
Prospectus [Line Items]  
Risk [Text Block]

NVDA INVESTING RISKS. The Fund will have significant exposure to NVDA through its investments in swap agreements that utilize NVDA as the reference asset. Accordingly, the Fund will subject to the risks of NVDA, set forth below.

 

NVDA ISSUER-SPECIFIC RISKS. Issuer-specific attributes may cause an investment held by the Fund to be more volatile than the market generally. The value of an individual security or particular type of security may be more volatile than the market as a whole and may perform differently from the value of the market as a whole. As of the date of this prospectus, in addition to the risks associated with companies in the information technology sector, NVDA faces risks associated with: failure to meet the evolving needs of its large markets – gaming, data center, professional visualization and automotive – and identifying new products, services and technologies; competition; changes in customer demand; supply chain issues; manufacturing delays; potential significant mismatches between supply and demand giving rise to product shortages or excessive inventory; the dependence on third-parties and their technology to manufacture, assemble, test, or package its products which reduces control over product quantity and quality, manufacturing yields, development, enhancement and product delivery schedules; significant product defects; international sales and operations, including adverse economic conditions; impacts from climate change, including water and energy availability; inability to realize the potential benefits from business investments and acquisitions; concentration of revenue from a limited number of partners, distributors and customers; the ability to attract, retain and motivate executives and key employees; system security and data protection breaches, including cyberattacks; business disruptions; the proper function of its business processes and information systems; fluctuations in operating results; increased scrutiny from shareholders and regulators regarding its environmental, social and governance responsibilities could result in increased operating expenses or adversely impact its reputation or ability to attract customers or suppliers; issues related to the responsible use of artificial intelligence (AI); ability to protect its intellectual property; ever changing and increasingly stringent data privacy and security laws and regulations; as well as other regulatory, tax related and legal issues, including the changing regulations regarding AI.

 

INDIRECT INVESTMENT RISK. NVIDIA Corporation is not affiliated with the Trust, the Fund, the Adviser, the Sub-Adviser or any affiliates thereof and is not involved with this offering in any way, and has no obligation to consider the Fund in taking any corporate actions that might affect the value of the Fund. The Trust, the Fund, the Adviser, the Sub-Adviser or any affiliate are not responsible for the performance of NVDA and make no representation as to the performance of NVDA. Investing in the Fund is not equivalent to investing in NVDA. Fund shareholders will not have voting rights or rights to receive dividends or other distributions or any other rights with respect to NVDA.

 

INFORMATION TECHNOLOGY COMPANIES RISK. Information technology companies face intense competition, both domestically and internationally, which may have an adverse effect on profit margins. Like other technology companies, information technology companies may have limited product lines, markets, financial resources or personnel. The products of information technology companies may face obsolescence due to rapid technological developments, frequent new product introduction, unpredictable changes in growth rates and competition for the services of qualified personnel. Companies in the information technology sector are heavily dependent on patent and intellectual property rights. The loss or impairment of these rights may adversely affect the profitability of these companies. Information technology companies are facing increased government and regulatory scrutiny and may be subject to adverse government or regulatory action.

 

SEMICONDUCTOR COMPANIES RISK. Semiconductor companies face intense competition, both domestically and internationally, and such competition may have an adverse effect on profit margins. Semiconductor companies may have limited product lines, markets, financial resources or personnel. Semiconductor companies’ supply chain and operations are dependent on the availability of materials that meet exacting standards and the use of third parties to provide components and services. Semiconductor companies may rely on a limited number of suppliers, or upon suppliers in a single location, for certain materials, equipment or tools. Finding and qualifying alternate or additional suppliers can be a lengthy process that can cause production delays or impose unforeseen costs, and such alternatives may not be available at all. Production can be disrupted by the unavailability of resources, such as water, silicon, electricity, gases and other materials. Suppliers may also increase prices or encounter cybersecurity or other issues that can disrupt production or increase production costs. The products of semiconductor companies may face obsolescence due to rapid technological developments and frequent new product introduction, unpredictable changes in growth rates and competition for the services of qualified personnel. Capital equipment expenditures could be substantial, and equipment generally suffers from rapid obsolescence. Companies in the semiconductor industry are heavily dependent on patent and intellectual property rights. The loss or impairment of these rights, would adversely affect the profitability of these companies.

 

LARGE CAPITALIZATION COMPANIES RISK. Large capitalization companies may be less able than smaller capitalization companies to adapt to changing market conditions. Large capitalization companies may be more mature and subject to more limited growth potential compared with smaller capitalization companies. During different market cycles, the performance of large capitalization companies has trailed the overall performance of the broader securities markets.

 

UNITED STATES RISK. Certain changes in the U.S. economy, such as when the U.S. economy weakens or when its financial markets decline, may have an adverse effect on the securities to which the Fund has exposure.

Risk [Text Block]

NON-DIVERSIFICATION RISK. As a “non-diversified” fund, the Fund may hold a smaller number of portfolio securities than many other funds. To the extent the Fund invests in a relatively small number of issuers, a decline in the market value of a particular security held by the Fund may affect its value more than if it invested in a larger number of issuers. The value of the Fund Shares may be more volatile than the values of shares of more diversified funds.

Roundhill TSLA WeeklyPay™ ETF | MARKET RISK  
Prospectus [Line Items]  
Risk [Text Block]

MARKET RISK. Market risk is the risk that a particular investment, or Fund Shares in general, may fall in value. Securities are subject to market fluctuations caused by real or perceived adverse economic, political, and regulatory factors or market developments, changes in interest rates, disruptions to trade, impositions of tariffs and perceived trends in securities prices. Fund Shares could decline in value or underperform other investments. In addition, local, regional or global events such as war, acts of terrorism, market manipulation, government defaults, government shutdowns, regulatory actions, political changes, diplomatic developments, the imposition of sanctions and other similar measures, spread of infectious diseases or other public health issues, recessions, natural disasters, or other events could have a significant negative impact on the Fund and its investments. Any of such circumstances could have a materially negative impact on the value of Fund Shares, the liquidity of an investment, and may result in increased market volatility. During any such events, Fund Shares may trade at increased premiums or discounts to their net asset value, the bid/ask spread on Fund Shares may widen and the returns on investment may fluctuate.

Roundhill TSLA WeeklyPay™ ETF | LIQUIDITY RISK  
Prospectus [Line Items]  
Risk [Text Block]

LIQUIDITY RISK. The market for swap agreements that reference TSLA shares may be subject to periods of illiquidity. During such times it may be difficult or impossible to buy or sell a position at the desired price. Market disruptions or volatility can also make it difficult to find a counterparty willing to transact at a reasonable price and sufficient size. Illiquid markets may cause losses, which could be significant. The large size of the positions which the Fund may acquire increases the risk of illiquidity, may make its positions more difficult to liquidate, and may increase the losses incurred while trying to do so. Such large positions also may impact the price of swap agreements on TSLA shares.

Roundhill TSLA WeeklyPay™ ETF | ACTIVE MANAGEMENT RISK  
Prospectus [Line Items]  
Risk [Text Block]

ACTIVE MANAGEMENT RISK. The Fund is actively-managed and its performance reflects investment decisions that the Adviser and/or Sub-Adviser makes for the Fund. Such judgments about the Fund’s investments may prove to be incorrect. If the investments selected and the strategies employed by the Fund fail to produce the intended results, the Fund could underperform as compared to other funds with similar investment objectives and/or strategies, or could have negative returns.

Roundhill TSLA WeeklyPay™ ETF | ACTIVE MARKET RISK

ACTIVE MARKET RISK. Although Fund Shares are listed for trading on the Exchange, there can be no assurance that an active trading market for Fund Shares will develop or be maintained. Fund Shares trade on the Exchange at market prices that may be below, at or above the Fund’s net asset value. Securities, including Fund Shares, are subject to market fluctuations and liquidity constraints that may be caused by such factors as economic, political, or regulatory developments, changes in interest rates, and/or perceived trends in securities prices. Fund Shares could decline in value or underperform other investments.

Risk [Text Block]

CONCENTRATION RISK. The Fund is susceptible to an increased risk of loss, including losses due to adverse events that affect the Fund’s investments more than the market as a whole, to the extent that the Fund’s investments are concentrated in investments that provide exposure to TSLA and the industry to which it is assigned.

Roundhill TSLA WeeklyPay™ ETF | COUNTERPARTY RISK  
Prospectus [Line Items]  
Risk [Text Block]

COUNTERPARTY RISK. Fund transactions involving a counterparty are subject to the risk that the counterparty will not fulfill its obligation to the Fund. Counterparty risk may arise because of the counterparty’s financial condition (i.e., financial difficulties, bankruptcy, or insolvency), market activities and developments, or other reasons, whether foreseen or not. A counterparty’s inability to fulfill its obligation may result in significant financial loss to the Fund. The Fund may be unable to recover its investment from the counterparty or may obtain a limited recovery, and/or recovery may be delayed.

CREDIT RISK. An issuer or other obligated party of a debt security may be unable or unwilling to make dividend, interest and/or principal payments when due. In addition, the value of a debt security may decline because of concerns about the issuer’s ability or unwillingness to make such payments.

Roundhill TSLA WeeklyPay™ ETF | CYBERSECURITY RISK  
Prospectus [Line Items]  
Risk [Text Block]

CYBERSECURITY RISK. Failures or breaches of the electronic systems of the Fund, the Fund’s adviser, sub-adviser, distributor and other service providers, market makers, Authorized Participants or the issuers of securities in which the Fund invests have the ability to cause disruptions, negatively impact the Fund’s business operations and/or potentially result in financial losses to the Fund and its shareholders. While the Fund has established business continuity plans and risk management systems seeking to address system breaches or failures, there are inherent limitations in such plans and systems. Furthermore, the Fund cannot control the cybersecurity plans and systems of the Fund’s other service providers, market makers, Authorized Participants or issuers of securities in which the Fund invests.

Roundhill TSLA WeeklyPay™ ETF | DEBT SECURITIES RISK  
Prospectus [Line Items]  
Risk [Text Block]

DEBT SECURITIES RISK. Investments in debt securities subject the holder to the credit risk of the issuer. Credit risk refers to the possibility that the issuer or other obligor of a security will not be able or willing to make payments of interest and principal when due. Generally, the value of debt securities will change inversely with changes in interest rates. To the extent that interest rates rise, certain underlying obligations may be paid off substantially slower than originally anticipated and the value of those securities may fall sharply. During periods of falling interest rates, the income received by the Fund may decline. If the principal on a debt security is prepaid before expected, the prepayments of principal may have to be reinvested in obligations paying interest at lower rates. Debt securities generally do not trade on a securities exchange making them generally less liquid and more difficult to value than common stock.

Roundhill TSLA WeeklyPay™ ETF | DERIVATIVES RISK  
Prospectus [Line Items]  
Risk [Text Block]

DERIVATIVES RISK. The use of derivative instruments involves risks different from, or possibly greater than, the risks associated with investing directly in securities and other traditional investments. These risks include: (i) the risk that the counterparty to a derivative transaction may not fulfill its contractual obligations; (ii) risk of mispricing or improper valuation; and (iii) the risk that changes in the value of the derivative may not correlate perfectly with the underlying asset. Derivative prices are highly volatile and may fluctuate substantially during a short period of time. Such prices are influenced by numerous factors that affect the markets, including, but not limited to: changing supply and demand relationships; government programs and policies; national and international political and economic events, changes in interest rates, inflation and deflation and changes in supply and demand relationships. Trading derivative instruments involves risks different from, or possibly greater than, the risks associated with investing directly in securities. Derivative contracts ordinarily have leverage inherent in their terms. The use of leverage may cause the Fund to liquidate portfolio positions when it would not be advantageous to do so in order to satisfy its obligations or to meet regulatory or contractual requirements for derivatives. The use of derivatives can magnify potential for gain or loss and, therefore, amplify the effects of market volatility on share price.

Roundhill TSLA WeeklyPay™ ETF | DISTRIBUTION TAX RISK  
Prospectus [Line Items]  
Risk [Text Block]

DISTRIBUTION TAX RISK. The Fund currently expects to make distributions on a weekly basis. Such frequent distributions may expose investors to increased tax liabilities. However, these distributions may exceed the Fund’s income and gains for the Fund’s taxable year. Distributions in excess of the Fund’s current and accumulated earnings and profits will be treated as a return of capital. A return of capital distribution generally will not be taxable but will reduce the shareholder’s cost basis and will result in a higher capital gain or lower capital loss when those Fund Shares on which the distribution was received are sold. Once a Fund shareholder’s cost basis is reduced to zero, further distributions will be treated as capital gain if the Fund shareholder holds Fund Shares as capital assets. Additionally, any capital returned through distributions will be distributed after payment of Fund fees and expenses. Because a portion of the Fund’s distributions may consist of return of capital, the Fund may not be an appropriate investment for investors who do not want their principal investment in the Fund to decrease over time or who do not wish to receive return of capital in a given period. In the event that a shareholder purchases Fund Shares shortly before a distribution by the Fund, the entire distribution may be taxable to the shareholder even though a portion of the distribution effectively represents a return of the purchase price.

Roundhill TSLA WeeklyPay™ ETF | ETF RISK  
Prospectus [Line Items]  
Risk [Text Block]

ETF RISK. The Fund may invest in ETFs. The value of an ETF held by the Fund will fluctuate over time based on fluctuations in the values of the assets held by the ETF, which may be affected by changes in general economic conditions, expectations for future growth and profits, interest rates and the supply and demand for those assets. When the Fund invests in an ETF, it will bear a proportionate share of the ETF’s expenses. Brokerage, tax and other expenses may negatively impact the performance of the ETF and, in turn, the value of the Fund Shares. An ETF that tracks an index may not exactly match the performance of the index due to cash drag, differences between the portfolio of the ETF and the components of the index, expenses and other factors.

Roundhill TSLA WeeklyPay™ ETF | INFLATION RISK  
Prospectus [Line Items]  
Risk [Text Block]

INFLATION RISK. Inflation risk is the risk that the value of assets or income from investments will be less in the future as inflation decreases the value of money. As inflation increases, the present value of the Fund’s assets and distributions may decline. This risk is more prevalent with respect to fixed income securities held by the Fund.

Roundhill TSLA WeeklyPay™ ETF | Interest Rate Risk [Member]  
Prospectus [Line Items]  
Risk [Text Block]

INTEREST RATE RISK. Interest rate risk is the risk that the value of the debt securities in the Fund’s portfolio will decline because of rising market interest rates. Interest rate risk is generally lower for shorter term debt securities and higher for longer-term debt securities. Duration is a reasonably accurate measure of a debt security’s price sensitivity to changes in interest rates and a common measure of interest rate risk. Duration measures a debt security’s expected life on a present value basis, taking into account the debt security’s yield, interest payments and final maturity. In general, duration represents the expected percentage change in the value of a security for an immediate 1% change in interest rates. For example, the price of a debt security with a three-year duration would be expected to drop by approximately 3% in response to a 1% increase in interest rates. Therefore, prices of debt securities with shorter durations tend to be less sensitive to interest rate changes than debt securities with longer durations. As the value of a debt security changes over time, so will its duration.

Roundhill TSLA WeeklyPay™ ETF | LEGISLATION AND LITIGATION RISK  
Prospectus [Line Items]  
Risk [Text Block]

LEGISLATION AND LITIGATION RISK. Legislation or litigation that affects the value of assets or securities held by the Fund may reduce the value of the Fund. From time to time, various legislative initiatives are proposed that may have a negative impact on certain assets or securities in which the Fund invests. In addition, litigation regarding any of the assets or securities owned by the Fund may negatively impact the value of the Shares. Such legislation or litigation may cause the Fund to lose value or may result in higher portfolio turnover if the Adviser determines to sell such a holding.

Roundhill TSLA WeeklyPay™ ETF | LEVERAGE RISK  
Prospectus [Line Items]  
Risk [Text Block]

LEVERAGE RISK. The Fund obtains investment exposure in excess of its net assets by utilizing leverage and may lose more money in market conditions that are adverse to its investment objectives than a fund that does not utilize leverage. An investment in the Fund is exposed to the risk that a decline in the weekly performance of shares of TSLA will be magnified. This means that an investment in the Fund will be reduced by an amount equal to 1.2% for every 1% weekly decline in the market value of the TSLA shares, not including the costs of financing leverage and other operating expenses, which would further reduce its value. The Fund could theoretically lose an amount greater than its net assets in the event the market value of TSLA shares decline more than 83.33% over a calendar week. Leverage will also have the effect of magnifying any differences in the Fund’s correlation with TSLA shares.

Roundhill TSLA WeeklyPay™ ETF | MONEY MARKET INSTRUMENTS RISK  
Prospectus [Line Items]  
Risk [Text Block]

MONEY MARKET INSTRUMENTS RISK. The value of money market instruments may be affected by changing interest rates and by changes in the credit ratings of the investments. If a significant amount of the Fund’s assets are invested in money market instruments, it will be more difficult for the Fund to achieve its investment objectives. An investment in a money market fund is not insured or guaranteed by the FDIC or any other government agency. It is possible to lose money by investing in a money market fund.

Roundhill TSLA WeeklyPay™ ETF | OPERATIONAL RISK  
Prospectus [Line Items]  
Risk [Text Block]

OPERATIONAL RISK. The Fund is subject to risks arising from various operational factors, including, but not limited to, human error, processing and communication errors, errors of the Fund’s service providers, counterparties or other third-parties, failed or inadequate processes and technology or systems failures. The Fund relies on third-parties for a range of services, including custody. Any delay or failure relating to engaging or maintaining such service providers may affect the Fund’s ability to meet its investment objectives. Although the Fund and the Adviser seek to reduce these operational risks through controls and procedures, there is no way to completely protect against such risks.

Roundhill TSLA WeeklyPay™ ETF | SPECIAL TAX RISK  
Prospectus [Line Items]  
Risk [Text Block]

SPECIAL TAX RISK. The Fund intends to qualify annually and to elect to be treated as a regulated investment company under the Internal Revenue Code of 1986, as amended (the “Code”). To qualify for the favorable U.S. federal income tax treatment generally accorded to regulated investment companies, the Fund must, among other things, (i) derive in each taxable year at least 90% of its gross income from dividends, interest, payments with respect to securities loans and gains from the sale or other disposition of stock, securities or foreign currencies or other income derived with respect to its business of investing in such stock, securities or currencies, or net income derived from interests in certain publicly traded partnerships; (ii) diversify its holdings so that, at the end of each quarter of the taxable year, (a) at least 50% of the market value of the Fund’s assets is represented by cash and cash items (including receivables), U.S. government securities, the securities of other regulated investment companies and other securities, with such other securities of any one issuer generally limited for the purposes of this calculation to an amount not greater than 5% of the value of the Fund’s total assets and not greater than 10% of the outstanding voting securities of such issuer, and (b) not more than 25% of the value of its total assets is invested in the securities (other than U.S. government securities or the securities of other regulated investment companies) of any one issuer, or two or more issuers which the Fund controls which are engaged in the same, similar or related trades or businesses, or the securities of one or more of certain publicly traded partnerships; and (iii) distribute at least 90% of its investment company taxable income (which includes, among other items, dividends, interest and net short-term capital gains in excess of net long-term capital losses) and at least 90% of its net tax-exempt interest income each taxable year. There are certain exceptions for failure to qualify if the failure is for reasonable cause or is de minimis, and certain corrective action is taken and certain tax payments are made by the Fund.

 

The authority with regard to swaps entered into by regulated investment companies is unclear both as to the qualification under the income test and the identification of the issuer under the diversification test. The Fund intends to take the position that because the swaps held by the Fund reference securities that the income on the swaps are “other income” from the Fund’s business of investing in stocks and securities. In addition, the Fund intends to manage its investments in the swaps so that neither the exposure to issuer of the referenced security nor the exposure to any one counterparty of the swaps will exceed 25% of the gross value of the Fund’s portfolio at the end of any quarter.

 

If the Fund were to fail to meet the qualifying income test or asset diversification test and fail to qualify as a RIC, it would be taxed in the same manner as an ordinary corporation, and distributions to its shareholders would not be deductible by the Fund in computing its taxable income, which would adversely affect the Fund’s performance.

Roundhill TSLA WeeklyPay™ ETF | STRUCTURAL ETF RISKS  
Prospectus [Line Items]  
Risk [Text Block]

STRUCTURAL ETF RISKS. The Fund is an ETF. Accordingly, it is subject to certain risks associated with its unique structure.

 

Market Participants Risk. Only an Authorized Participant may engage in creation or redemption transactions directly with the Fund, and none of those Authorized Participants is obligated to engage in creation and/or redemption transactions. The Fund has a limited number of institutions that may act as Authorized Participants on an agency basis (i.e., on behalf of other market participants). To the extent that Authorized Participants exit the business or are unable to proceed with creation or redemption orders with respect to the Fund and no other Authorized Participant is able to step forward to create or redeem, Fund Shares may be more likely to trade at a premium or discount to NAV and possibly face trading halts or delisting. The Fund may also rely on a small number of third-party market makers to provide a market for the purchase and sale of Fund Shares but such market makers are under no obligation to do so. Decisions by Authorized Participants or market makers to reduce their role or step away from these activities in times of market stress could inhibit the effectiveness of the arbitrage process in maintaining the relationship between the underlying values of the Fund’s portfolio securities and the Fund’s market price. Any trading halt or other problem relating to the trading activity of these market makers or any issues disrupting the Authorized Participants’ ability to proceed with creation and/or redemption orders could result in a dramatic change in the spread between the Fund’s net asset value and the price at which Fund Shares are trading on the Exchange, which could result in a decrease in value of Fund Shares. This reduced effectiveness could result in Fund Shares trading at a premium or discount to net asset value and also in greater than normal intraday bid-ask spreads Fund Shares.

 

Cash Transactions Risk. The Fund currently expects to effect a significant portion of its creations and redemptions for cash, rather than in-kind securities. Paying redemption proceeds in cash rather than through in-kind delivery of portfolio securities may require the Fund to dispose of or sell portfolio securities or other assets at an inopportune time to obtain the cash needed to meet redemption orders. This may cause the Fund to sell a security and recognize a capital gain or loss that might not have been incurred if it had made a redemption in-kind. As a result, the Fund may pay out higher or lower annual capital gains distributions than ETFs that redeem in-kind. The use of cash creations and redemptions may also cause the Fund’s Shares to trade in the market at greater bid-ask spreads or greater premiums or discounts to the Fund’s net asset value (“NAV”). Furthermore, the Fund may not be able to execute cash transactions for creation and redemption purposes at the same price used to determine the Fund’s NAV. To the extent that the maximum additional charge for creation or redemption transactions is insufficient to cover the execution shortfall, the Fund’s performance could be negatively impacted.

 

Costs of Buying and Selling Fund Shares. Due to the costs of buying or selling Fund Shares, including brokerage commissions imposed by brokers and bid/ask spreads, frequent trading of Fund Shares may significantly reduce investment results and an investment in Fund Shares may not be advisable for investors who anticipate regularly making small investments.

 

Premium/Discount Risk. As with all ETFs, Fund Shares may be bought and sold in the secondary market at market prices. The trading prices of Fund Shares in the secondary market may differ from the Fund’s daily NAV per Fund Share and there may be times when the market price of the Fund Shares is more than the NAV per Fund Share (premium) or less than the NAV per Fund Share (discount). If a shareholder purchases Fund Shares at a time when the market price is at a premium to the NAV or sells Fund Shares at a time when the market price is at a discount to the NAV, the shareholder may pay more for, or receive less than, the underlying value of the Fund Shares, respectively. This risk is heightened in times of market volatility or periods of steep market declines.

 

Trading Risks. Although Fund Shares are listed for trading on the Exchange and may be traded on U.S. exchanges other than the Exchange, there can be no assurance that Fund Shares will trade with any volume, or at all, on any stock exchange. In stressed market conditions, the liquidity of Fund Shares may begin to mirror the liquidity of the Fund’s underlying portfolio holdings, which can be significantly less liquid than Fund Shares. Trading in Fund Shares on the Exchange may be halted due to market conditions or for reasons that, in the view of the Exchange, make trading in Fund Shares inadvisable. In addition, trading in Fund Shares on the Exchange is subject to trading halts caused by extraordinary market volatility pursuant to the Exchange’s “circuit breaker” rules. There can be no assurance that the requirements of the Exchange necessary to maintain the listing of the Fund will continue to be met or will remain unchanged.

Roundhill TSLA WeeklyPay™ ETF | U.S. GOVERNMENT SECURITIES RISK  
Prospectus [Line Items]  
Risk [Text Block]

U.S. GOVERNMENT SECURITIES RISK. U.S. government securities are subject to interest rate risk but generally do not involve the credit risks associated with investments in other types of debt securities. As a result, the yields available from U.S. government securities are generally lower than the yields available from other debt securities. U.S. government securities are guaranteed only as to the timely payment of interest and the payment of principal when held to maturity.

Roundhill TSLA WeeklyPay™ ETF | VALUATION RISK  
Prospectus [Line Items]  
Risk [Text Block]

VALUATION RISK. The Fund may hold securities or other assets that may be valued on the basis of factors other than market quotations. This may occur because the asset or security does not trade on a centralized exchange, or in times of market turmoil or reduced liquidity. There are multiple methods that can be used to value a portfolio holding when market quotations are not readily available. The value established for any portfolio holding at a point in time might differ from what would be produced using a different methodology or if it had been priced using market quotations. Portfolio holdings that are valued using techniques other than market quotations, including “fair valued” assets or securities, may be subject to greater fluctuation in their valuations from one day to the next than if market quotations were used. In addition, there is no assurance that the Fund could sell or close out a portfolio position for the value established for it at any time, and it is possible that the Fund would incur a loss because a portfolio position is sold or closed out at a discount to the valuation established by the Fund at that time. The Fund’s ability to value investments may be impacted by technological issues or errors by pricing services or other third-party service providers.

Roundhill TSLA WeeklyPay™ ETF | EQUITY SECURITIES RISK  
Prospectus [Line Items]  
Risk [Text Block]

EQUITY SECURITIES RISK. Equity securities are subject to changes in value, and their values may be more volatile than those of other asset classes. Equity securities prices fluctuate for several reasons, including changes in investors’ perceptions of the financial condition of an issuer or the general condition of the relevant equity market, such as market volatility, or when political or economic events affecting an issuer occur. Common stock prices may be particularly sensitive to rising interest rates, as the cost of capital rises and borrowing costs increase. Common stocks generally subject their holders to more risks than preferred stocks and debt securities because common stockholders’ claims are subordinated to those of holders of preferred stocks and debt securities upon the bankruptcy of the issuer.

Roundhill TSLA WeeklyPay™ ETF | SWAP AGREEMENTS RISK  
Prospectus [Line Items]  
Risk [Text Block]

SWAP AGREEMENTS RISK. The Fund will utilize swap agreements to derive its exposure to shares of TSLA. Swap agreements may involve greater risks than direct investment in securities as they may be leveraged and are subject to credit risk, counterparty risk and valuation risk. A swap agreement could result in losses if the underlying reference or asset does not perform as anticipated. In addition, many swaps trade over-the-counter and may be considered illiquid. It may not be possible for the Fund to liquidate a swap position at an advantageous time or price, which may result in significant losses.

Roundhill TSLA WeeklyPay™ ETF | REGULATED INVESTMENT COMPANY TAX RISKS  
Prospectus [Line Items]  
Risk [Text Block]

REGULATED INVESTMENT COMPANY TAX RISKS. The Fund intends to qualify annually and to elect to be treated as a regulated investment company under the Internal Revenue Code of 1986, as amended (the “Code”). To qualify for the favorable U.S. federal income tax treatment generally accorded to regulated investment companies, the Fund must, among other things, (i) derive in each taxable year at least 90% of its gross income from dividends, interest, payments with respect to securities loans and gains from the sale or other disposition of stock, securities or foreign currencies or other income derived with respect to its business of investing in such stock, securities or currencies, or net income derived from interests in certain publicly traded partnerships; (ii) diversify its holdings so that, at the end of each quarter of the taxable year, (a) at least 50% of the market value of the Fund’s assets is represented by cash and cash items (including receivables), U.S. government securities, the securities of other regulated investment companies and other securities, with such other securities of any one issuer generally limited for the purposes of this calculation to an amount not greater than 5% of the value of the Fund’s total assets and not greater than 10% of the outstanding voting securities of such issuer, and (b) not more than 25% of the value of its total assets is invested in the securities (other than U.S. government securities or the securities of other regulated investment companies) of any one issuer, or two or more issuers which the Fund controls which are engaged in the same, similar or related trades or businesses, or the securities of one or more of certain publicly traded partnerships; and (iii) distribute at least 90% of its investment company taxable income (which includes, among other items, dividends, interest and net short-term capital gains in excess of net long-term capital losses) and at least 90% of its net tax-exempt interest income each taxable year. There are certain exceptions for failure to qualify if the failure is for reasonable cause or is de minimis, and certain corrective action is taken and certain tax payments are made by the Fund.

 

If the Fund were to fail to meet the qualifying income test or asset diversification test and fail to qualify as a RIC, it would be taxed in the same manner as an ordinary corporation, and distributions to its shareholders would not be deductible by the Fund in computing its taxable income, which would adversely affect the Fund’s performance.

Roundhill TSLA WeeklyPay™ ETF | LARGE SHAREHOLDER RISK  
Prospectus [Line Items]  
Risk [Text Block]

LARGE SHAREHOLDER RISK. Certain shareholders, including affiliated funds advised by the Adviser, may from time to time own a significant portion of the Fund’s shares. In addition, a third-party investor, the Adviser or an affiliate of the Adviser (“Affiliate”), an authorized participant, a market maker, or another entity may invest in the Fund and hold its investment for a limited period solely to facilitate the commencement of the Fund or to help the Fund achieve a specified size or scale. There can be no assurance that any large shareholder will not redeem its investment, that the size of the Fund will be maintained at such levels, or that the Fund will continue to meet applicable listing requirements. Redemptions by large shareholders could have a significant negative impact on the Fund. In addition, transactions by large shareholders may account for a large percentage of the trading volume on the Fund’s listing exchange and may, therefore, have a material upward or downward effect on the market price of the shares.

 

To the extent that a significant percentage of the Fund’s shares are owned or controlled by a small number of account shareholders (or a single account shareholder), including funds or accounts over which the Adviser or an Affiliate has investment discretion, the Fund is subject to the risk that those shareholders may purchase or redeem Fund shares in significant amounts rapidly or unexpectedly, including as a result of an asset allocation decision made by the Adviser or an Affiliate. This may adversely affect the Fund’s performance if the Adviser is forced to sell portfolio securities or invest cash when it would not otherwise choose to do so. Redemptions of a large number of shares may affect the liquidity of the Fund’s portfolio, increase the Fund’s transaction costs, and accelerate the realization of taxable income and/or gains. In addition, a large redemption could result in the Fund’s current expenses being allocated over a smaller asset base, leading to an increase in the Fund’s gross expense ratio. Large purchases of the Fund’s shares may also adversely affect the Fund’s performance to the extent that the Fund is delayed in investing new cash or otherwise maintains a larger cash position than it ordinarily would, particularly if the Fund accepts cash for an order for the purchase of creation units of the Fund’s shares.

Roundhill TSLA WeeklyPay™ ETF | TSLA INVESTING RISKS  
Prospectus [Line Items]  
Risk [Text Block]

TSLA INVESTING RISKS. The Fund will have significant exposure to TSLA through its investments in swap agreements that utilize TSLA as the reference asset. Accordingly, the Fund will subject to the risks of TSLA, set forth below.

 

TSLA ISSUER-SPECIFIC RISKS. Issuer-specific attributes may cause an investment held by the Fund to be more volatile than the market generally. The value of an individual security or particular type of security may be more volatile than the market as a whole and may perform differently from the value of the market as a whole. As of the date of this prospectus, in addition to the risks associated with companies involved in the production of electric and autonomous vehicles as well as automotive companies, Tesla, Inc. faces risks associated with: potential delays in launching and scaling production of products and features; suppliers may be unable to delivery components according to schedule or at acceptable prices or volumes; projected construction timelines may be hard to predict; growing global sales, delivery and installation capabilities as well as increasing the global vehicle charging network may be difficult; maintaining and growing access to battery cells may be difficult; the future demand for electric vehicles is unpredictable; competition is increasing from a growing list of established and new competitors; issues with manufacturing lithium-ion cells or other components for its electric vehicles; the ability to maintain and expand international operations; products or features may contain defects or take longer than expect to be fully functional; product liability claims; maintaining public credibility and confidence for the long term, including the management of recalls and warranties; the potential for difficulties with growing or maintaining the various offered financing programs; managing ongoing obligations with the Research Foundation for the State University of New York relating to the Gigafactory New York; the ability to attract, hire and retain key employees or qualified personnel; being highly dependent on the services of Elon Musk, its Chief Executive Officer; system security and data protection breaches, including cyberattacks; the potential for union activities to cause disruptions; as well as other operational, regulatory, tax related and legal issues. Additionally, communications by Mr. Musk to the public may significantly impact the trading price of Tesla, Inc.’s common stock.

 

ELECTRIC AND AUTONOMOUS VEHICLE RISK. The electric and autonomous vehicle industries are in a phase of rapid technological innovation. Companies may face challenges in developing reliable, efficient, and cost-effective technologies, which could delay product rollouts or reduce competitiveness. The success of electric and autonomous vehicle companies is influenced by government policies, such as subsidies, tax incentives, emissions regulations, and autonomous driving laws. Changes or uncertainty in these policies may adversely impact the growth prospects of such companies. Electric and autonomous vehicle development requires significant upfront capital for research and development, production facilities, and infrastructure. Companies may face difficulties in securing adequate funding, particularly in volatile market conditions or periods of rising interest rates. In addition, electric and autonomous vehicle companies depend on the availability of raw materials, particularly for batteries (e.g., lithium, cobalt, nickel). Supply chain disruptions, geopolitical tensions, or material shortages could increase costs and hinder production. Consumer adoption of electric and autonomous vehicles depends on factors such as vehicle affordability, charging infrastructure availability, range anxiety, and consumer trust in autonomous driving technology. Slower-than-expected adoption could impact company revenues. Lastly, the market for electric and autonomous vehicles is highly competitive, with established automakers, startups, and technology companies vying for market share. Intense competition may lead to pricing pressure, reduced margins, or market consolidation.

 

INDIRECT INVESTMENT RISK. Tesla, Inc. is not affiliated with the Trust, the Fund, the Adviser, the Sub-Adviser or any affiliates thereof and is not involved with this offering in any way, and has no obligation to consider the Fund in taking any corporate actions that might affect the value of the Fund. The Trust, the Fund, the Adviser, the Sub-Adviser or any affiliate are not responsible for the performance of TSLA and make no representation as to the performance of TSLA. Investing in the Fund is not equivalent to investing in TSLA. Fund shareholders will not have voting rights or rights to receive dividends or other distributions or any other rights with respect to TSLA.

 

CONSUMER DISCRETIONARY COMPANIES RISK. The success of consumer product manufacturers and retailers is tied closely to the performance of domestic and international economies, interest rates, exchange rates, supply chains, competition, consumer confidence, changes in demographics and consumer preferences. Companies in the consumer discretionary sector depend heavily on disposable household income and consumer spending, and may be strongly affected by social trends and marketing campaigns. These companies may be subject to severe competition, which may have an adverse impact on their profitability.

 

LARGE CAPITALIZATION COMPANIES RISK. Large capitalization companies may be less able than smaller capitalization companies to adapt to changing market conditions. Large capitalization companies may be more mature and subject to more limited growth potential compared with smaller capitalization companies. During different market cycles, the performance of large capitalization companies has trailed the overall performance of the broader securities markets.

 

UNITED STATES RISK. Certain changes in the U.S. economy, such as when the U.S. economy weakens or when its financial markets decline, may have an adverse effect on the securities to which the Fund has exposure.

NON-DIVERSIFICATION RISK. As a “non-diversified” fund, the Fund may hold a smaller number of portfolio securities than many other funds. To the extent the Fund invests in a relatively small number of issuers, a decline in the market value of a particular security held by the Fund may affect its value more than if it invested in a larger number of issuers. The value of the Fund Shares may be more volatile than the values of shares of more diversified funds.

Roundhill Magnificent Seven Covered Call ETF | MARKET RISK  
Prospectus [Line Items]  
Risk [Text Block]

MARKET RISK. Market risk is the risk that a particular investment, or Fund Shares in general, may fall in value. Securities are subject to market fluctuations caused by real or perceived adverse economic, political, and regulatory factors or market developments, changes in interest rates, disruptions to trade, impositions of tariffs and perceived trends in securities prices. Fund Shares could decline in value or underperform other investments. In addition, local, regional or global events such as war, acts of terrorism, market manipulation, government defaults, government shutdowns, regulatory actions, political changes, diplomatic developments, the imposition of sanctions and other similar measures, spread of infectious diseases or other public health issues, recessions, natural disasters, or other events could have a significant negative impact on the Fund and its investments. Any of such circumstances could have a materially negative impact on the value of Fund Shares, the liquidity of an investment, and may result in increased market volatility. During any such events, Fund Shares may trade at increased premiums or discounts to their net asset value, the bid/ask spread on Fund Shares may widen and the returns on investment may fluctuate.

Roundhill Magnificent Seven Covered Call ETF | COVERED CALL STRATEGY RISK  
Prospectus [Line Items]  
Risk [Text Block]

COVERED CALL STRATEGY RISK. A covered call strategy involves writing (selling) covered call options in return for the receipt of premiums. The seller of the option gives up the opportunity to benefit from value increases in the MAGS ETF above the strike price of the sold call options, but continues to bear the risk of the MAGS ETF price declines. The premiums received from the options may not be sufficient to offset any losses sustained from MAGS ETF price declines. Exchanges may suspend the trading of options during periods of abnormal market volatility. Suspension of trading may mean that an option seller is unable to sell options at a time that may be desirable or advantageous to do so.

Roundhill Magnificent Seven Covered Call ETF | OPTIONS RISK  
Prospectus [Line Items]  
Risk [Text Block]

OPTIONS RISK. The use of options involves investment strategies and risks different from those associated with ordinary portfolio securities transactions and depends on the ability of the Fund’s portfolio managers to forecast market movements correctly. The prices of options are volatile and are influenced by, among other things, actual and anticipated changes in the value of the underlying instrument, or in interest or currency exchange rates, including the anticipated volatility, which in turn are affected by fiscal and monetary policies and by national and international political and economic events. The effective use of options also depends on the Fund’s ability to terminate option positions at times deemed desirable to do so. There is no assurance that the Fund will be able to effect closing transactions at any particular time or at an acceptable price. In addition, there may at times be an imperfect correlation between the movement in values of options and their underlying securities and there may at times not be a liquid secondary market for certain options. Lastly, the trading of options is subject to transaction costs that may impact the Fund’s returns.

Roundhill Magnificent Seven Covered Call ETF | LIQUIDITY RISK  
Prospectus [Line Items]  
Risk [Text Block]

LIQUIDITY RISK. The market for options may be subject to periods of illiquidity. During such times it may be difficult or impossible to buy or sell a position at the desired price. Market disruptions or volatility can also make it difficult to find a counterparty willing to transact at a reasonable price and sufficient size. Illiquid markets may cause losses, which could be significant. The large size of the positions which the Fund may acquire increases the risk of illiquidity, may make its positions more difficult to liquidate, and may increase the losses incurred while trying to do so. Such large positions also may impact the price of options held by the Fund.

Roundhill Magnificent Seven Covered Call ETF | ACTIVE MANAGEMENT RISK

ACTIVE MANAGEMENT RISK. The Fund is actively-managed and its performance reflects investment decisions that the Adviser and/or Sub-Adviser makes for the Fund. Such judgments about the Fund’s investments may prove to be incorrect. If the investments selected and the strategies employed by the Fund fail to produce the intended results, the Fund could underperform as compared to other funds with similar investment objectives and/or strategies, or could have negative returns. The Adviser/Sub-Adviser will seek to employ the Fund’s investment strategy regardless of whether there are periods of adverse market, economic, or other conditions and will not seek to take temporary defensive positions during such periods.

Roundhill Magnificent Seven Covered Call ETF | CLEARING MEMBER DEFAULT RISK  
Prospectus [Line Items]  
Risk [Text Block]

CLEARING MEMBER DEFAULT RISK. Transactions in some types of derivatives, including the options held by the Fund, are required to be centrally cleared (“cleared derivatives”). In a transaction involving cleared derivatives, the Fund’s counterparty is a clearinghouse, such as the OCC, rather than a bank or broker. Since the Fund is not a member of clearinghouses, and only members of a clearinghouse (“clearing members”) can participate directly in the clearinghouse, the Fund will hold cleared derivatives through accounts at clearing members. With regard its cleared derivatives positions, the Fund will make payments (including margin payments) to, and receive payments from, a clearinghouse through their accounts at clearing members. Customer funds held at a clearing organization in connection with any option contracts are held in a commingled omnibus account and are not identified to the name of the clearing member’s individual customers. As a result, assets deposited by the Fund with any clearing member as margin for its options position may, in certain circumstances, be used to satisfy losses of other clients of the Fund’s clearing member. In addition, although clearing members guarantee performance of their clients’ obligations to the clearinghouse, there is a risk that the assets of the Fund might not be fully protected in the event of the clearing member’s bankruptcy. The Fund is also subject to the risk that a limited number of clearing members are willing to transact on the Fund’s behalf, which heightens the risks associated with a clearing member’s default. If a clearing member defaults, the Fund could lose some or all of the benefits of a transaction entered into by the Fund with the clearing member. The loss of a clearing member for the Fund to transact with could result in increased transaction costs and other operational issues that could impede the Fund’s ability to implement its investment strategy. If the Fund cannot find a clearing member to transact with on the Fund’s behalf, the Fund may be unable to effectively implement its investment strategy.

Roundhill Magnificent Seven Covered Call ETF | CONCENTRATION RISK  
Prospectus [Line Items]  
Risk [Text Block]

CONCENTRATION RISK. The Fund may be susceptible to an increased risk of loss, including losses due to adverse events that affect the Fund’s investments more than the market as a whole, to the extent that the Fund’s investments are concentrated in the securities and/or other assets of a particular issuer or issuers, country, group of countries, region, market, industry, group of industries, sector, market segment or asset class.

Roundhill Magnificent Seven Covered Call ETF | CURRENT MARKET CONDITIONS RISK  
Prospectus [Line Items]  
Risk [Text Block]

CURRENT MARKET CONDITIONS RISK. Current market conditions risk is the risk that a particular investment, or Fund Shares in general, may fall in value due to current market conditions. As a means to fight inflation, which remains at elevated levels, the Federal Reserve and certain foreign central banks have raised interest rates; however, the Federal Reserve has recently lowered interest rates and may continue to do so. U.S. regulators have proposed several changes to market and issuer regulations which would directly impact the Fund, and any regulatory changes could adversely impact the Fund’s ability to achieve its investment strategies or make certain investments. Recent and potential future bank failures could result in disruption to the broader banking industry or markets generally and reduce confidence in financial institutions and the economy as a whole, which may also heighten market volatility and reduce liquidity. Additionally, challenges in commercial real estate markets, including rising interest rates, declining valuations and increasing vacancies, could have a broader impact on financial markets. The ongoing adversarial political climate in the United States, as well as political and diplomatic events both domestic and abroad, have and may continue to have an adverse impact the U.S. regulatory landscape, markets and investor behavior, which could have a negative impact on the Fund’s investments and operations. The change in administration resulting from the 2024 United States national elections could result in significant impacts to international trade relations, tax and immigration policies, and other aspects of the national and international political and financial landscape, which could affect, among other things, inflation and the securities markets generally. Other unexpected political, regulatory and diplomatic events within the U.S. and abroad may affect investor and consumer confidence and may adversely impact financial markets and the broader economy. For example, ongoing armed conflicts between Russia and Ukraine in Europe and among Israel, Iran, Hamas and other militant groups in the Middle East, have caused and could continue to cause significant market disruptions and volatility within the markets in Russia, Europe, the Middle East and the United States. The hostilities and sanctions resulting from those hostilities have and could continue to have a significant impact on certain Fund investments as well as Fund performance and liquidity. The economies of the United States and its trading partners, as well as the financial markets generally, may be adversely impacted by trade disputes, including the imposition of tariffs, and other matters. For example, the United States has imposed trade barriers and restrictions on China. In addition, the Chinese government is engaged in a longstanding dispute with Taiwan, continually threatening an invasion. If the political climate between the United States and China does not improve or continues to deteriorate, if China were to attempt invading Taiwan, or if other geopolitical conflicts develop or worsen, economies, markets and individual securities may be adversely affected, and the value of the Fund’s assets may go down. A public health crisis and the ensuing policies enacted by governments and central banks may cause significant volatility and uncertainty in global financial markets, negatively impacting global growth prospects. As the COVID-19 global pandemic illustrated, such events may affect certain geographic regions, countries, sectors and industries more significantly than others. Advancements in technology may also adversely impact markets and the overall performance of the Fund. For instance, the economy may be significantly impacted by the advanced development and increased regulation of artificial intelligence. Additionally, cyber security breaches of both government and non-government entities could have negative impacts on infrastructure and the ability of such entities, including the Fund, to operate properly. These events, and any other future events, may adversely affect the prices and liquidity of the Fund’s portfolio investments and could result in disruptions in the trading markets.

Roundhill Magnificent Seven Covered Call ETF | CYBERSECURITY RISK  
Prospectus [Line Items]  
Risk [Text Block]

CYBERSECURITY RISK. Failures or breaches of the electronic systems of the Fund, the Fund’s adviser, sub-adviser, distributor and other service providers, market makers, Authorized Participants or the issuers of securities in which the Fund invests have the ability to cause disruptions, negatively impact the Fund’s business operations and/or potentially result in financial losses to the Fund and its shareholders. While the Fund has established business continuity plans and risk management systems seeking to address system breaches or failures, there are inherent limitations in such plans and systems. Furthermore, the Fund cannot control the cybersecurity plans and systems of the Fund’s other service providers, market makers, Authorized Participants or issuers of securities in which the Fund invests.

Roundhill Magnificent Seven Covered Call ETF | DERIVATIVES RISK  
Prospectus [Line Items]  
Risk [Text Block]

DERIVATIVES RISK. The use of derivative instruments (i.e. options contracts) involves risks different from, or possibly greater than, the risks associated with investing directly in securities and other traditional investments. These risks include: (i) the risk that the counterparty to a derivative transaction may not fulfill its contractual obligations; (ii) risk of mispricing or improper valuation; and (iii) the risk that changes in the value of the derivative may not correlate perfectly with the underlying asset. Derivative prices are highly volatile and may fluctuate substantially during a short period of time. Such prices are influenced by numerous factors that affect the markets, including, but not limited to: changing supply and demand relationships; government programs and policies; national and international political and economic events, changes in interest rates, inflation and deflation and changes in supply and demand relationships. Trading derivative instruments involves risks different from, or possibly greater than, the risks associated with investing directly in securities. Derivative contracts ordinarily have leverage inherent in their terms. The use of leverage may cause the Fund to liquidate portfolio positions when it would not be advantageous to do so in order to satisfy its obligations or to meet regulatory or contractual requirements for derivatives. The use of derivatives can magnify potential for gain or loss and, therefore, amplify the effects of market volatility on the Fund Share price.

Roundhill Magnificent Seven Covered Call ETF | DISTRIBUTION TAX RISK  
Prospectus [Line Items]  
Risk [Text Block]

DISTRIBUTION TAX RISK. The Fund currently expects to make distributions on a weekly basis. These distributions may exceed the Fund’s income and gains for the Fund’s taxable year. Distributions in excess of the Fund’s current and accumulated earnings and profits will be treated as a return of capital. A return of capital distribution generally will not be taxable but will reduce the shareholder’s cost basis and will result in a higher capital gain or lower capital loss when those Fund Shares on which the distribution was received are sold. Once a Fund shareholder’s cost basis is reduced to zero, further distributions will be treated as capital gain if the Fund shareholder holds Fund Shares as capital assets. Additionally, any capital returned through distributions will be distributed after payment of Fund fees and expenses. Because a portion of the Fund’s distributions may consist of return of capital, the Fund may not be an appropriate investment for investors who do not want their principal investment in the Fund to decrease over time or who do not wish to receive return of capital in a given period. In the event that a shareholder purchases Fund Shares shortly before a distribution by the Fund, the entire distribution may be taxable to the shareholder even though a portion of the distribution effectively represents a return of the purchase price.

Roundhill Magnificent Seven Covered Call ETF | FLEX OPTIONS RISK  
Prospectus [Line Items]  
Risk [Text Block]

FLEX OPTIONS RISK. Trading FLEX Options involves risks different from, or possibly greater than, the risks associated with investing directly in securities. The Fund may experience losses from specific FLEX Option positions and certain FLEX Option positions may expire worthless. The FLEX Options are listed on an exchange; however, no one can guarantee that a liquid secondary trading market will exist for the FLEX Options. In the event that trading in the FLEX Options is limited or absent, the value of the Fund’s FLEX Options may decrease. In a less liquid market for the FLEX Options, liquidating the FLEX Options may require the payment of a premium (for written FLEX Options) or acceptance of a discounted price (for purchased FLEX Options) and may take longer to complete. A less liquid trading market may adversely impact the value of the FLEX Options and Fund shares and result in the Fund being unable to achieve its investment objectives. Less liquidity in the trading of the Fund’s FLEX Options could have an impact on the prices paid or received by the Fund for the FLEX Options in connection with creations and redemptions of the Fund’s shares. Depending on the nature of this impact to pricing, the Fund may be forced to pay more for redemptions (or receive less for creations) than the price at which it currently values the FLEX Options. Such overpayment or under collection could reduce the Fund’s ability to achieve its investment objectives. Additionally, in a less liquid market for the FLEX Options, the liquidation of a large number of options may more significantly impact the price. A less liquid trading market may adversely impact the value of the FLEX Options and the value of your investment. The trading in FLEX Options may be less deep and liquid than the market for certain other exchange-traded options, non-customized options or other securities.

Roundhill Magnificent Seven Covered Call ETF | INFLATION RISK  
Prospectus [Line Items]  
Risk [Text Block]

INFLATION RISK. Inflation risk is the risk that the value of assets or income from investments will be less in the future as inflation decreases the value of money. As inflation increases, the present value of the Fund’s assets and distributions may decline. This risk is more prevalent with respect to fixed income securities held by the Fund.

Roundhill Magnificent Seven Covered Call ETF | OPERATIONAL RISK  
Prospectus [Line Items]  
Risk [Text Block]

OPERATIONAL RISK. The Fund is subject to risks arising from various operational factors, including, but not limited to, human error, processing and communication errors, errors of the Fund’s service providers, counterparties or other third-parties, failed or inadequate processes and technology or systems failures. The Fund relies on third-parties for a range of services, including custody. Any delay or failure relating to engaging or maintaining such service providers may affect the Fund’s ability to meet its investment objectives. Although the Fund and the Adviser seek to reduce these operational risks through controls and procedures, there is no way to completely protect against such risks.

Roundhill Magnificent Seven Covered Call ETF | STRUCTURAL ETF RISKS  
Prospectus [Line Items]  
Risk [Text Block]

STRUCTURAL ETF RISKS. The Fund is an ETF. Accordingly, it is subject to certain risks associated with its unique structure.

 

Market Participants Risk. Only an Authorized Participant may engage in creation or redemption transactions directly with the Fund, and none of those Authorized Participants is obligated to engage in creation and/or redemption transactions. The Fund has a limited number of institutions that may act as Authorized Participants on an agency basis (i.e., on behalf of other market participants). To the extent that Authorized Participants exit the business or are unable to proceed with creation or redemption orders with respect to the Fund and no other Authorized Participant is able to step forward to create or redeem, Fund Shares may be more likely to trade at a premium or discount to NAV and possibly face trading halts or delisting. The Fund may also rely on a small number of third-party market makers to provide a market for the purchase and sale of Fund Shares but such market makers are under no obligation to do so. Decisions by Authorized Participants or market makers to reduce their role or step away from these activities in times of market stress could inhibit the effectiveness of the arbitrage process in maintaining the relationship between the underlying values of the Fund’s portfolio securities and the Fund’s market price. Any trading halt or other problem relating to the trading activity of these market makers or any issues disrupting the Authorized Participants’ ability to proceed with creation and/or redemption orders could result in a dramatic change in the spread between the Fund’s net asset value and the price at which Fund Shares are trading on the Exchange, which could result in a decrease in value of Fund Shares. This reduced effectiveness could result in Fund Shares trading at a premium or discount to net asset value and also in greater than normal intraday bid-ask spreads Fund Shares.

 

Cash Transactions Risk. The Fund may effect a significant portion of its creations and redemptions for cash, rather than in-kind securities. Paying redemption proceeds in cash rather than through in-kind delivery of portfolio securities may require the Fund to dispose of or sell portfolio securities or other assets at an inopportune time to obtain the cash needed to meet redemption orders. This may cause the Fund to sell a security and recognize a capital gain or loss that might not have been incurred if it had made a redemption in-kind. As a result, the Fund may pay out higher or lower annual capital gains distributions than ETFs that redeem in-kind. The use of cash creations and redemptions may also cause the Fund Shares to trade in the market at greater bid-ask spreads or greater premiums or discounts to the Fund’s NAV. Furthermore, the Fund may not be able to execute cash transactions for creation and redemption purposes at the same price used to determine the Fund’s NAV. To the extent that the maximum additional charge for creation or redemption transactions is insufficient to cover the execution shortfall, the Fund’s performance could be negatively impacted.

 

Active Market Risk. Although Fund Shares are listed for trading on the Exchange, there can be no assurance that an active trading market for Fund Shares will develop or be maintained. Fund Shares trade on the Exchange at market prices that may be below, at or above the Fund’s net asset value. Securities, including Fund Shares, are subject to market fluctuations and liquidity constraints that may be caused by such factors as economic, political, or regulatory developments, changes in interest rates, and/or perceived trends in securities prices. Fund Shares could decline in value or underperform other investments.

 

Costs of Buying and Selling Fund Shares. Due to the costs of buying or selling Fund Shares, including brokerage commissions imposed by brokers and bid/ask spreads, frequent trading of Fund Shares may significantly reduce investment results and an investment in Fund Shares may not be advisable for investors who anticipate regularly making small investments.

 

Premium/Discount Risk. As with all ETFs, Fund Shares may be bought and sold in the secondary market at market prices. The trading prices of Fund Shares in the secondary market may differ from the Fund’s daily net asset value per share and there may be times when the market price of the shares is more than the net asset value per share (premium) or less than the net asset value per share (discount). If a shareholder purchases Fund Shares at a time when the market price is at a premium to the net asset value or sells Fund Shares at a time when the market price is at a discount to the net asset value, the shareholder may pay more for, or receive less than, the underlying value of the Fund Shares, respectively. This risk is heightened in times of market volatility or periods of steep market declines.

 

Trading Risks. Although Fund Shares are listed for trading on the Exchange and may be traded on U.S. exchanges other than the Exchange, there can be no assurance that Fund Shares will trade with any volume, or at all, on any stock exchange. In stressed market conditions, the liquidity of Fund Shares may begin to mirror the liquidity of the Fund’s underlying portfolio holdings, which can be significantly less liquid than Fund Shares. Trading in Fund Shares on the Exchange may be halted due to market conditions or for reasons that, in the view of the Exchange, make trading in Fund Shares inadvisable. In addition, trading in Fund Shares on the Exchange is subject to trading halts caused by extraordinary market volatility pursuant to the Exchange’s “circuit breaker” rules. There can be no assurance that the requirements of the Exchange necessary to maintain the listing of the Fund will continue to be met or will remain unchanged.

Roundhill Magnificent Seven Covered Call ETF | VALUATION RISK  
Prospectus [Line Items]  
Risk [Text Block]

VALUATION RISK. The Fund may hold securities or other assets that may be valued on the basis of factors other than market quotations. This may occur because the asset or security does not trade on a centralized exchange, or in times of market turmoil or reduced liquidity. There are multiple methods that can be used to value a portfolio holding when market quotations are not readily available. The value established for any portfolio holding at a point in time might differ from what would be produced using a different methodology or if it had been priced using market quotations. Portfolio holdings that are valued using techniques other than market quotations, including “fair valued” assets or securities, may be subject to greater fluctuation in their valuations from one day to the next than if market quotations were used. In addition, there is no assurance that the Fund could sell or close out a portfolio position for the value established for it at any time, and it is possible that the Fund would incur a loss because a portfolio position is sold or closed out at a discount to the valuation established by the Fund at that time. The Fund’s ability to value investments may be impacted by technological issues or errors by pricing services or other third-party service providers.

Roundhill Magnificent Seven Covered Call ETF | INFORMATION TECHNOLOGY COMPANIES RISK  
Prospectus [Line Items]  
Risk [Text Block]

INFORMATION TECHNOLOGY COMPANIES RISK. Information technology companies face intense competition, both domestically and internationally, which may have an adverse effect on profit margins. Like other technology companies, information technology companies may have limited product lines, markets, financial resources or personnel. The products of information technology companies may face obsolescence due to rapid technological developments, frequent new product introduction, unpredictable changes in growth rates and competition for the services of qualified personnel. Companies in the information technology sector are heavily dependent on patent and intellectual property rights. The loss or impairment of these rights may adversely affect the profitability of these companies. Information technology companies are facing increased government and regulatory scrutiny and may be subject to adverse government or regulatory action.

Roundhill Magnificent Seven Covered Call ETF | EARLY CLOSE/LATE CLOSE/TRADING HALT RISK  
Prospectus [Line Items]  
Risk [Text Block]

EARLY CLOSE/LATE CLOSE/TRADING HALT RISK. An exchange or market may close early, close late or issue trading halts on specific securities or financial instruments. As a result, the ability to trade certain securities or financial instruments may be restricted, which may disrupt the Fund’s creation and redemption process, potentially affect the price at which Fund Shares trade in the secondary market, and/or result in the Fund being unable to trade certain securities or financial instruments at all. In these circumstances, the Fund may be unable to rebalance its portfolio, may be unable to accurately price its investments and/or may incur substantial trading losses. If trading in Fund Shares are halted, investors may be temporarily unable to trade Fund Shares.

Roundhill Magnificent Seven Covered Call ETF | MAGS ETF RISKS  
Prospectus [Line Items]  
Risk [Text Block]

MAGS ETF RISKS. The Fund will have significant exposure to the MAGS ETF through its investments in shares of the MAGS ETF. Accordingly, the Fund will subject to the risks of the MAGS ETF, set forth below. In addition to these risks, the MAGS ETF is also subject to the following risks to which the Fund is also subject, which are described within the section entitled “Principal Risks”: Active Management Risk, Active Market Risk, Asset Class Risk, Concentration Risk, Cybersecurity Risk, Information Technology Risk, Operational Risk and Structural ETF Risk.

 

EQUITY SECURITIES RISK. Equity securities are subject to changes in value, and their values may be more volatile than those of other asset classes. Equity securities prices fluctuate for several reasons, including changes in investors’ perceptions of the financial condition of an issuer or the general condition of the relevant equity market, such as market volatility, or when political or economic events affecting an issuer occur. Common stock prices may be particularly sensitive to rising interest rates, as the cost of capital rises and borrowing costs increase. Common stocks generally subject their holders to more risks than preferred stocks and debt securities because common stockholders’ claims are subordinated to those of holders of preferred stocks and debt securities upon the bankruptcy of the issuer.

 

ISSUER RISK. The performance of an ETF depends on the performance of individual securities to which the ETF has exposure. Changes in the financial condition or credit rating of an issuer of those securities may cause the value of the securities to decline. There is no guarantee that an issuer that paid dividends in the past will continue to do so in the future or will continue paying dividends at the same level.

 

LARGE CAPITALIZATION COMPANIES RISK. Large capitalization companies may be less able than smaller capitalization companies to adapt to changing market conditions. Large capitalization companies may be more mature and subject to more limited growth potential compared with smaller capitalization companies. During different market cycles, the performance of large capitalization companies has trailed the overall performance of the broader securities markets.

MARKET RISK. Market risk is the risk that a particular investment, or Fund Shares in general, may fall in value. Securities are subject to market fluctuations caused by real or perceived adverse economic, political, and regulatory factors or market developments, changes in interest rates, disruptions to trade, impositions of tariffs and perceived trends in securities prices. Fund Shares could decline in value or underperform other investments. In addition, local, regional or global events such as war, acts of terrorism, market manipulation, government defaults, government shutdowns, regulatory actions, political changes, diplomatic developments, the imposition of sanctions and other similar measures, spread of infectious diseases or other public health issues, recessions, natural disasters, or other events could have a significant negative impact on the Fund and its investments. Any of such circumstances could have a materially negative impact on the value of Fund Shares, the liquidity of an investment, and may result in increased market volatility. During any such events, Fund Shares may trade at increased premiums or discounts to their net asset value, the bid/ask spread on Fund Shares may widen and the returns on investment may fluctuate.

Illiquid markets may cause losses, which could be significant. The large size of the positions which the Fund may acquire increases the risk of illiquidity, may make its positions more difficult to liquidate, and may increase the losses incurred while trying to do so.

COUNTERPARTY RISK. Fund transactions involving a counterparty are subject to the risk that the counterparty will not fulfill its obligation to the Fund. Counterparty risk may arise because of the counterparty’s financial condition (i.e., financial difficulties, bankruptcy, or insolvency), market activities and developments, or other reasons, whether foreseen or not. A counterparty’s inability to fulfill its obligation may result in significant financial loss to the Fund. The Fund may be unable to recover its investment from the counterparty or may obtain a limited recovery, and/or recovery may be delayed.

CURRENT MARKET CONDITIONS RISK. Current market conditions risk is the risk that a particular investment, or Fund Shares in general, may fall in value due to current market conditions. As a means to fight inflation, which remains at elevated levels, the Federal Reserve and certain foreign central banks have raised interest rates; however, the Federal Reserve has recently lowered interest rates and may continue to do so. U.S. regulators have proposed several changes to market and issuer regulations which would directly impact the Fund, and any regulatory changes could adversely impact the Fund’s ability to achieve its investment strategies or make certain investments. Recent and potential future bank failures could result in disruption to the broader banking industry or markets generally and reduce confidence in financial institutions and the economy as a whole, which may also heighten market volatility and reduce liquidity. Additionally, challenges in commercial real estate markets, including rising interest rates, declining valuations and increasing vacancies, could have a broader impact on financial markets. The ongoing adversarial political climate in the United States, as well as political and diplomatic events both domestic and abroad, have and may continue to have an adverse impact the U.S. regulatory landscape, markets and investor behavior, which could have a negative impact on the Fund’s investments and operations. The change in administration resulting from the 2024 United States national elections could result in significant impacts to international trade relations, tax and immigration policies, and other aspects of the national and international political and financial landscape, which could affect, among other things, inflation and the securities markets generally. Other unexpected political, regulatory and diplomatic events within the U.S. and abroad may affect investor and consumer confidence and may adversely impact financial markets and the broader economy. For example, ongoing armed conflicts between Russia and Ukraine in Europe and among Israel, Iran, Hamas and other militant groups in the Middle East, have caused and could continue to cause significant market disruptions and volatility within the markets in Russia, Europe, the Middle East and the United States. The hostilities and sanctions resulting from those hostilities have and could continue to have a significant impact on certain Fund investments as well as Fund performance and liquidity. The economies of the United States and its trading partners, as well as the financial markets generally, may be adversely impacted by trade disputes, including the imposition of tariffs, and other matters. For example, the United States has imposed trade barriers and restrictions on China. In addition, the Chinese government is engaged in a longstanding dispute with Taiwan, continually threatening an invasion. If the political climate between the United States and China does not improve or continues to deteriorate, if China were to attempt invading Taiwan, or if other geopolitical conflicts develop or worsen, economies, markets and individual securities may be adversely affected, and the value of the Fund’s assets may go down. A public health crisis and the ensuing policies enacted by governments and central banks may cause significant volatility and uncertainty in global financial markets, negatively impacting global growth prospects. As the COVID-19 global pandemic illustrated, such events may affect certain geographic regions, countries, sectors and industries more significantly than others. Advancements in technology may also adversely impact markets and the overall performance of the Fund. For instance, the economy may be significantly impacted by the advanced development and increased regulation of artificial intelligence. Additionally, cyber security breaches of both government and non-government entities could have negative impacts on infrastructure and the ability of such entities, including the Fund, to operate properly. These events, and any other future events, may adversely affect the prices and liquidity of the Fund’s portfolio investments and could result in disruptions in the trading markets.

Roundhill ABNB WeeklyPay™ ETF | CYBERSECURITY RISK

Risk [Text Block]

CYBERSECURITY RISK. Failures or breaches of the electronic systems of the Fund, the Fund’s adviser, sub-adviser, distributor and other service providers, market makers, Authorized Participants or the issuers of securities in which the Fund invests have the ability to cause disruptions, negatively impact the Fund’s business operations and/or potentially result in financial losses to the Fund and its shareholders. While the Fund has established business continuity plans and risk management systems seeking to address system breaches or failures, there are inherent limitations in such plans and systems. Furthermore, the Fund cannot control the cybersecurity plans and systems of the Fund’s other service providers, market makers, Authorized Participants or issuers of securities in which the Fund invests.

Roundhill ABNB WeeklyPay™ ETF | DEBT SECURITIES RISK  
Prospectus [Line Items]  
Risk [Text Block]

DEBT SECURITIES RISK. Investments in debt securities subject the holder to the credit risk of the issuer. Credit risk refers to the possibility that the issuer or other obligor of a security will not be able or willing to make payments of interest and principal when due. Generally, the value of debt securities will change inversely with changes in interest rates. To the extent that interest rates rise, certain underlying obligations may be paid off substantially slower than originally anticipated and the value of those securities may fall sharply. During periods of falling interest rates, the income received by the Fund may decline. If the principal on a debt security is prepaid before expected, the prepayments of principal may have to be reinvested in obligations paying interest at lower rates. Debt securities generally do not trade on a securities exchange making them generally less liquid and more difficult to value than common stock.

Roundhill ABNB WeeklyPay™ ETF | DERIVATIVES RISK  
Prospectus [Line Items]  
Risk [Text Block]

DERIVATIVES RISK. The use of derivative instruments involves risks different from, or possibly greater than, the risks associated with investing directly in securities and other traditional investments. These risks include: (i) the risk that the counterparty to a derivative transaction may not fulfill its contractual obligations; (ii) risk of mispricing or improper valuation; and (iii) the risk that changes in the value of the derivative may not correlate perfectly with the underlying asset. Derivative prices are highly volatile and may fluctuate substantially during a short period of time. Such prices are influenced by numerous factors that affect the markets, including, but not limited to: changing supply and demand relationships; government programs and policies; national and international political and economic events, changes in interest rates, inflation and deflation and changes in supply and demand relationships. Trading derivative instruments involves risks different from, or possibly greater than, the risks associated with investing directly in securities. Derivative contracts ordinarily have leverage inherent in their terms. The use of leverage may cause the Fund to liquidate portfolio positions when it would not be advantageous to do so in order to satisfy its obligations or to meet regulatory or contractual requirements for derivatives. The use of derivatives can magnify potential for gain or loss and, therefore, amplify the effects of market volatility on share price.

Roundhill ABNB WeeklyPay™ ETF | DISTRIBUTION TAX RISK  
Prospectus [Line Items]  
Risk [Text Block]

DISTRIBUTION TAX RISK. The Fund currently expects to make distributions on a weekly basis. Such frequent distributions may expose investors to increased tax liabilities. However, these distributions may exceed the Fund’s income and gains for the Fund’s taxable year. Distributions in excess of the Fund’s current and accumulated earnings and profits will be treated as a return of capital. A return of capital distribution generally will not be taxable but will reduce the shareholder’s cost basis and will result in a higher capital gain or lower capital loss when those Fund Shares on which the distribution was received are sold. Once a Fund shareholder’s cost basis is reduced to zero, further distributions will be treated as capital gain if the Fund shareholder holds Fund Shares as capital assets. Additionally, any capital returned through distributions will be distributed after payment of Fund fees and expenses. Because a portion of the Fund’s distributions may consist of return of capital, the Fund may not be an appropriate investment for investors who do not want their principal investment in the Fund to decrease over time or who do not wish to receive return of capital in a given period. In the event that a shareholder purchases Fund Shares shortly before a distribution by the Fund, the entire distribution may be taxable to the shareholder even though a portion of the distribution effectively represents a return of the purchase price.

Roundhill ABNB WeeklyPay™ ETF | ETF RISK  
Prospectus [Line Items]  
Risk [Text Block]

ETF RISK. The Fund may invest in ETFs. The value of an ETF held by the Fund will fluctuate over time based on fluctuations in the values of the assets held by the ETF, which may be affected by changes in general economic conditions, expectations for future growth and profits, interest rates and the supply and demand for those assets. When the Fund invests in an ETF, it will bear a proportionate share of the ETF’s expenses. Brokerage, tax and other expenses may negatively impact the performance of the ETF and, in turn, the value of the Fund Shares. An ETF that tracks an index may not exactly match the performance of the index due to cash drag, differences between the portfolio of the ETF and the components of the index, expenses and other factors.

Roundhill ABNB WeeklyPay™ ETF | INFLATION RISK  
Prospectus [Line Items]  
Risk [Text Block]

INFLATION RISK. Inflation risk is the risk that the value of assets or income from investments will be less in the future as inflation decreases the value of money. As inflation increases, the present value of the Fund’s assets and distributions may decline. This risk is more prevalent with respect to fixed income securities held by the Fund.

Roundhill ABNB WeeklyPay™ ETF | Interest Rate Risk [Member]  
Prospectus [Line Items]  
Risk [Text Block]

INTEREST RATE RISK. Interest rate risk is the risk that the value of the debt securities in the Fund’s portfolio will decline because of rising market interest rates. Interest rate risk is generally lower for shorter term debt securities and higher for longer-term debt securities. Duration is a reasonably accurate measure of a debt security’s price sensitivity to changes in interest rates and a common measure of interest rate risk. Duration measures a debt security’s expected life on a present value basis, taking into account the debt security’s yield, interest payments and final maturity. In general, duration represents the expected percentage change in the value of a security for an immediate 1% change in interest rates. For example, the price of a debt security with a three-year duration would be expected to drop by approximately 3% in response to a 1% increase in interest rates. Therefore, prices of debt securities with shorter durations tend to be less sensitive to interest rate changes than debt securities with longer durations. As the value of a debt security changes over time, so will its duration.

Roundhill ABNB WeeklyPay™ ETF | LEGISLATION AND LITIGATION RISK  
Prospectus [Line Items]  
Risk [Text Block]

LEGISLATION AND LITIGATION RISK. Legislation or litigation that affects the value of assets or securities held by the Fund may reduce the value of the Fund. From time to time, various legislative initiatives are proposed that may have a negative impact on certain assets or securities in which the Fund invests. In addition, litigation regarding any of the assets or securities owned by the Fund may negatively impact the value of the Shares. Such legislation or litigation may cause the Fund to lose value or may result in higher portfolio turnover if the Adviser determines to sell such a holding.

Roundhill ABNB WeeklyPay™ ETF | LEVERAGE RISK  
Prospectus [Line Items]  
Risk [Text Block]

LEVERAGE RISK. The Fund obtains investment exposure in excess of its net assets by utilizing leverage and may lose more money in market conditions that are adverse to its investment objectives than a fund that does not utilize leverage. An investment in the Fund is exposed to the risk that a decline in the weekly performance of shares of ABNB will be magnified. This means that an investment in the Fund will be reduced by an amount equal to 1.2% for every 1% weekly decline in the market value of the ABNB shares, not including the costs of financing leverage and other operating expenses, which would further reduce its value. The Fund could theoretically lose an amount greater than its net assets in the event the market value of ABNB shares decline more than 83.33% over a calendar week. Leverage will also have the effect of magnifying any differences in the Fund’s correlation with ABNB shares.

Roundhill ABNB WeeklyPay™ ETF | MONEY MARKET INSTRUMENTS RISK  
Prospectus [Line Items]  
Risk [Text Block]

MONEY MARKET INSTRUMENTS RISK. The value of money market instruments may be affected by changing interest rates and by changes in the credit ratings of the investments. If a significant amount of the Fund’s assets are invested in money market instruments, it will be more difficult for the Fund to achieve its investment objectives. An investment in a money market fund is not insured or guaranteed by the FDIC or any other government agency. It is possible to lose money by investing in a money market fund.

Roundhill ABNB WeeklyPay™ ETF | OPERATIONAL RISK  
Prospectus [Line Items]  
Risk [Text Block]

OPERATIONAL RISK. The Fund is subject to risks arising from various operational factors, including, but not limited to, human error, processing and communication errors, errors of the Fund’s service providers, counterparties or other third-parties, failed or inadequate processes and technology or systems failures. The Fund relies on third-parties for a range of services, including custody. Any delay or failure relating to engaging or maintaining such service providers may affect the Fund’s ability to meet its investment objectives. Although the Fund and the Adviser seek to reduce these operational risks through controls and procedures, there is no way to completely protect against such risks.

Roundhill ABNB WeeklyPay™ ETF | SPECIAL TAX RISK  
Prospectus [Line Items]  
Risk [Text Block]

SPECIAL TAX RISK. The Fund intends to qualify annually and to elect to be treated as a regulated investment company under the Internal Revenue Code of 1986, as amended (the “Code”). To qualify for the favorable U.S. federal income tax treatment generally accorded to regulated investment companies, the Fund must, among other things, (i) derive in each taxable year at least 90% of its gross income from dividends, interest, payments with respect to securities loans and gains from the sale or other disposition of stock, securities or foreign currencies or other income derived with respect to its business of investing in such stock, securities or currencies, or net income derived from interests in certain publicly traded partnerships; (ii) diversify its holdings so that, at the end of each quarter of the taxable year, (a) at least 50% of the market value of the Fund’s assets is represented by cash and cash items (including receivables), U.S. government securities, the securities of other regulated investment companies and other securities, with such other securities of any one issuer generally limited for the purposes of this calculation to an amount not greater than 5% of the value of the Fund’s total assets and not greater than 10% of the outstanding voting securities of such issuer, and (b) not more than 25% of the value of its total assets is invested in the securities (other than U.S. government securities or the securities of other regulated investment companies) of any one issuer, or two or more issuers which the Fund controls which are engaged in the same, similar or related trades or businesses, or the securities of one or more of certain publicly traded partnerships; and (iii) distribute at least 90% of its investment company taxable income (which includes, among other items, dividends, interest and net short-term capital gains in excess of net long-term capital losses) and at least 90% of its net tax-exempt interest income each taxable year. There are certain exceptions for failure to qualify if the failure is for reasonable cause or is de minimis, and certain corrective action is taken and certain tax payments are made by the Fund.

 

The authority with regard to swaps entered into by regulated investment companies is unclear both as to the qualification under the income test and the identification of the issuer under the diversification test. The Fund intends to take the position that because the swaps held by the Fund reference securities that the income on the swaps are “other income” from the Fund’s business of investing in stocks and securities. In addition, the Fund intends to manage its investments in the swaps so that neither the exposure to issuer of the referenced security nor the exposure to any one counterparty of the swaps will exceed 25% of the gross value of the Fund’s portfolio at the end of any quarter.

 

If the Fund were to fail to meet the qualifying income test or asset diversification test and fail to qualify as a RIC, it would be taxed in the same manner as an ordinary corporation, and distributions to its shareholders would not be deductible by the Fund in computing its taxable income, which would adversely affect the Fund’s performance.

Roundhill ABNB WeeklyPay™ ETF | STRUCTURAL ETF RISKS  
Prospectus [Line Items]  
Risk [Text Block]

STRUCTURAL ETF RISKS. The Fund is an ETF. Accordingly, it is subject to certain risks associated with its unique structure.

 

Market Participants Risk. Only an Authorized Participant may engage in creation or redemption transactions directly with the Fund, and none of those Authorized Participants is obligated to engage in creation and/or redemption transactions. The Fund has a limited number of institutions that may act as Authorized Participants on an agency basis (i.e., on behalf of other market participants). To the extent that Authorized Participants exit the business or are unable to proceed with creation or redemption orders with respect to the Fund and no other Authorized Participant is able to step forward to create or redeem, Fund Shares may be more likely to trade at a premium or discount to NAV and possibly face trading halts or delisting. The Fund may also rely on a small number of third-party market makers to provide a market for the purchase and sale of Fund Shares but such market makers are under no obligation to do so. Decisions by Authorized Participants or market makers to reduce their role or step away from these activities in times of market stress could inhibit the effectiveness of the arbitrage process in maintaining the relationship between the underlying values of the Fund’s portfolio securities and the Fund’s market price. Any trading halt or other problem relating to the trading activity of these market makers or any issues disrupting the Authorized Participants’ ability to proceed with creation and/or redemption orders could result in a dramatic change in the spread between the Fund’s net asset value and the price at which Fund Shares are trading on the Exchange, which could result in a decrease in value of Fund Shares. This reduced effectiveness could result in Fund Shares trading at a premium or discount to net asset value and also in greater than normal intraday bid-ask spreads Fund Shares.

 

Cash Transactions Risk. The Fund currently expects to effect a significant portion of its creations and redemptions for cash, rather than in-kind securities. Paying redemption proceeds in cash rather than through in-kind delivery of portfolio securities may require the Fund to dispose of or sell portfolio securities or other assets at an inopportune time to obtain the cash needed to meet redemption orders. This may cause the Fund to sell a security and recognize a capital gain or loss that might not have been incurred if it had made a redemption in-kind. As a result, the Fund may pay out higher or lower annual capital gains distributions than ETFs that redeem in-kind. The use of cash creations and redemptions may also cause the Fund’s Shares to trade in the market at greater bid-ask spreads or greater premiums or discounts to the Fund’s NAV. Furthermore, the Fund may not be able to execute cash transactions for creation and redemption purposes at the same price used to determine the Fund’s NAV. To the extent that the maximum additional charge for creation or redemption transactions is insufficient to cover the execution shortfall, the Fund’s performance could be negatively impacted.

 

Costs of Buying and Selling Fund Shares. Due to the costs of buying or selling Fund Shares, including brokerage commissions imposed by brokers and bid/ask spreads, frequent trading of Fund Shares may significantly reduce investment results and an investment in Fund Shares may not be advisable for investors who anticipate regularly making small investments.

 

Premium/Discount Risk. As with all ETFs, Fund Shares may be bought and sold in the secondary market at market prices. The trading prices of Fund Shares in the secondary market may differ from the Fund’s daily net asset value per share and there may be times when the market price of the shares is more than the net asset value per share (premium) or less than the net asset value per share (discount). If a shareholder purchases Fund Shares at a time when the market price is at a premium to the net asset value or sells Fund Shares at a time when the market price is at a discount to the net asset value, the shareholder may pay more for, or receive less than, the underlying value of the Fund Shares, respectively. This risk is heightened in times of market volatility or periods of steep market declines.

 

Trading Risks. Although Fund Shares are listed for trading on the Exchange and may be traded on U.S. exchanges other than the Exchange, there can be no assurance that Fund Shares will trade with any volume, or at all, on any stock exchange. In stressed market conditions, the liquidity of Fund Shares may begin to mirror the liquidity of the Fund’s underlying portfolio holdings, which can be significantly less liquid than Fund Shares. Trading in Fund Shares on the Exchange may be halted due to market conditions or for reasons that, in the view of the Exchange, make trading in Fund Shares inadvisable. In addition, trading in Fund Shares on the Exchange is subject to trading halts caused by extraordinary market volatility pursuant to the Exchange’s “circuit breaker” rules. There can be no assurance that the requirements of the Exchange necessary to maintain the listing of the Fund will continue to be met or will remain unchanged.

Roundhill ABNB WeeklyPay™ ETF | U.S. GOVERNMENT SECURITIES RISK  
Prospectus [Line Items]  
Risk [Text Block]

U.S. GOVERNMENT SECURITIES RISK. U.S. government securities are subject to interest rate risk but generally do not involve the credit risks associated with investments in other types of debt securities. As a result, the yields available from U.S. government securities are generally lower than the yields available from other debt securities. U.S. government securities are guaranteed only as to the timely payment of interest and the payment of principal when held to maturity.

Roundhill ABNB WeeklyPay™ ETF | VALUATION RISK  
Prospectus [Line Items]  
Risk [Text Block]

VALUATION RISK. The Fund may hold securities or other assets that may be valued on the basis of factors other than market quotations. This may occur because the asset or security does not trade on a centralized exchange, or in times of market turmoil or reduced liquidity. There are multiple methods that can be used to value a portfolio holding when market quotations are not readily available. The value established for any portfolio holding at a point in time might differ from what would be produced using a different methodology or if it had been priced using market quotations. Portfolio holdings that are valued using techniques other than market quotations, including “fair valued” assets or securities, may be subject to greater fluctuation in their valuations from one day to the next than if market quotations were used. In addition, there is no assurance that the Fund could sell or close out a portfolio position for the value established for it at any time, and it is possible that the Fund would incur a loss because a portfolio position is sold or closed out at a discount to the valuation established by the Fund at that time. The Fund’s ability to value investments may be impacted by technological issues or errors by pricing services or other third-party service providers.

Roundhill ABNB WeeklyPay™ ETF | EQUITY SECURITIES RISK  
Prospectus [Line Items]  
Risk [Text Block]

EQUITY SECURITIES RISK. Equity securities are subject to changes in value, and their values may be more volatile than those of other asset classes. Equity securities prices fluctuate for several reasons, including changes in investors’ perceptions of the financial condition of an issuer or the general condition of the relevant equity market, such as market volatility, or when political or economic events affecting an issuer occur. Common stock prices may be particularly sensitive to rising interest rates, as the cost of capital rises and borrowing costs increase. Common stocks generally subject their holders to more risks than preferred stocks and debt securities because common stockholders’ claims are subordinated to those of holders of preferred stocks and debt securities upon the bankruptcy of the issuer.

Roundhill ABNB WeeklyPay™ ETF | SWAP AGREEMENTS RISK  
Prospectus [Line Items]  
Risk [Text Block]

SWAP AGREEMENTS RISK. The Fund will utilize swap agreements to derive its exposure to shares of ABNB. Swap agreements may involve greater risks than direct investment in securities as they may be leveraged and are subject to credit risk, counterparty risk and valuation risk. A swap agreement could result in losses if the underlying reference or asset does not perform as anticipated. In addition, many swaps trade over-the-counter and may be considered illiquid. It may not be possible for the Fund to liquidate a swap position at an advantageous time or price, which may result in significant losses.

Roundhill ABNB WeeklyPay™ ETF | NEW FUND RISK

NEW FUND RISK. The Fund is a recently organized investment company with a limited operating history. As a result, prospective investors have a limited track record or history on which to base their investment decision.

Prospectus [Line Items]  
Risk [Text Block]

REGULATED INVESTMENT COMPANY TAX RISKS. The Fund intends to qualify annually and to elect to be treated as a regulated investment company under the Internal Revenue Code of 1986, as amended (the “Code”). To qualify for the favorable U.S. federal income tax treatment generally accorded to regulated investment companies, the Fund must, among other things, (i) derive in each taxable year at least 90% of its gross income from dividends, interest, payments with respect to securities loans and gains from the sale or other disposition of stock, securities or foreign currencies or other income derived with respect to its business of investing in such stock, securities or currencies, or net income derived from interests in certain publicly traded partnerships; (ii) diversify its holdings so that, at the end of each quarter of the taxable year, (a) at least 50% of the market value of the Fund’s assets is represented by cash and cash items (including receivables), U.S. government securities, the securities of other regulated investment companies and other securities, with such other securities of any one issuer generally limited for the purposes of this calculation to an amount not greater than 5% of the value of the Fund’s total assets and not greater than 10% of the outstanding voting securities of such issuer, and (b) not more than 25% of the value of its total assets is invested in the securities (other than U.S. government securities or the securities of other regulated investment companies) of any one issuer, or two or more issuers which the Fund controls which are engaged in the same, similar or related trades or businesses, or the securities of one or more of certain publicly traded partnerships; and (iii) distribute at least 90% of its investment company taxable income (which includes, among other items, dividends, interest and net short-term capital gains in excess of net long-term capital losses) and at least 90% of its net tax-exempt interest income each taxable year. There are certain exceptions for failure to qualify if the failure is for reasonable cause or is de minimis, and certain corrective action is taken and certain tax payments are made by the Fund.

 

If the Fund were to fail to meet the qualifying income test or asset diversification test and fail to qualify as a RIC, it would be taxed in the same manner as an ordinary corporation, and distributions to its shareholders would not be deductible by the Fund in computing its taxable income, which would adversely affect the Fund’s performance.

Roundhill ABNB WeeklyPay™ ETF | LARGE SHAREHOLDER RISK  
Prospectus [Line Items]  
Risk [Text Block]

LARGE SHAREHOLDER RISK. Certain shareholders, including affiliated funds advised by the Adviser, may from time to time own a significant portion of the Fund’s shares. In addition, a third-party investor, the Adviser or an affiliate of the Adviser (“Affiliate”), an authorized participant, a market maker, or another entity may invest in the Fund and hold its investment for a limited period solely to facilitate the commencement of the Fund or to help the Fund achieve a specified size or scale. There can be no assurance that any large shareholder will not redeem its investment, that the size of the Fund will be maintained at such levels, or that the Fund will continue to meet applicable listing requirements. Redemptions by large shareholders could have a significant negative impact on the Fund. In addition, transactions by large shareholders may account for a large percentage of the trading volume on the Fund’s listing exchange and may, therefore, have a material upward or downward effect on the market price of the shares.

 

To the extent that a significant percentage of the Fund’s shares are owned or controlled by a small number of account shareholders (or a single account shareholder), including funds or accounts over which the Adviser or an Affiliate has investment discretion, the Fund is subject to the risk that those shareholders may purchase or redeem Fund shares in significant amounts rapidly or unexpectedly, including as a result of an asset allocation decision made by the Adviser or an Affiliate. This may adversely affect the Fund’s performance if the Adviser is forced to sell portfolio securities or invest cash when it would not otherwise choose to do so. Redemptions of a large number of shares may affect the liquidity of the Fund’s portfolio, increase the Fund’s transaction costs, and accelerate the realization of taxable income and/or gains. In addition, a large redemption could result in the Fund’s current expenses being allocated over a smaller asset base, leading to an increase in the Fund’s gross expense ratio. Large purchases of the Fund’s shares may also adversely affect the Fund’s performance to the extent that the Fund is delayed in investing new cash or otherwise maintains a larger cash position than it ordinarily would, particularly if the Fund accepts cash for an order for the purchase of creation units of the Fund’s shares.

Roundhill ABNB WeeklyPay™ ETF | ABNB INVESTING RISKS  
Prospectus [Line Items]  
Risk [Text Block]

ABNB INVESTING RISKS. The Fund will have significant exposure to ABNB through its investments in swap agreements that utilize ABNB as the reference asset. Accordingly, the Fund will subject to the risks of ABNB, set forth below.

 

ABNB ISSUER-SPECIFIC RISKS. Issuer-specific attributes may cause an investment held by the Fund to be more volatile than the market generally. The value of an individual security or particular type of security may be more volatile than the market as a whole and may perform differently from the value of the market as a whole. The short-term rental market is highly competitive, with ABNB facing challenges from traditional hotels, emerging short-term rental platforms and online travel agencies. Increased competition could lead to reduced market share, pressure on pricing, and higher marketing expenses. ABNB’s revenue depends on the availability of hosts and the demand from guests. Factors such as economic downturns, travel restrictions, or health crises (e.g., pandemics) can lead to decreased travel demand, affecting booking rates and occupancy. ABNB operates in numerous jurisdictions, each with its own set of laws and regulations concerning short-term rentals. Changes in local laws, zoning restrictions, or the introduction of stricter regulations could limit the availability of listings, impose fines, or lead to suspension of services in key markets. As a digital platform, ABNB’s operations depend on robust IT systems, including website functionality, mobile applications and data security measures. Technical failures, cyberattacks or data breaches could disrupt services, compromise user data and erode trust in the platform. A significant portion of ABNB’s revenue is derived from popular tourist destinations. Economic challenges, natural disasters, or political instability in these areas can lead to reduced bookings and financial losses. ABNB’s decentralized model means it has limited control over the quality and safety of listings. Negative guest experiences, property damages, or safety incidents can lead to reputational harm and potential legal liabilities.

 

CONSUMER DISCRETIONARY COMPANIES RISK. The success of consumer product manufacturers and retailers is tied closely to the performance of domestic and international economies, interest rates, exchange rates, supply chains, competition, consumer confidence, changes in demographics and consumer preferences. Companies in the consumer discretionary sector depend heavily on disposable household income and consumer spending, and may be strongly affected by social trends and marketing campaigns. These companies may be subject to severe competition, which may have an adverse impact on their profitability.

 

INDIRECT INVESTMENT RISK. Airbnb, Inc. is not affiliated with the Trust, the Fund, the Adviser, the Sub-Adviser or any affiliates thereof and is not involved with this offering in any way, and has no obligation to consider the Fund in taking any corporate actions that might affect the value of the Fund. The Trust, the Fund, the Adviser, the Sub-Adviser or any affiliate are not responsible for the performance of ABNB and make no representation as to the performance of ABNB. Investing in the Fund is not equivalent to investing in ABNB. Fund shareholders will not have voting rights or rights to receive dividends or other distributions or any other rights with respect to ABNB.

 

LARGE CAPITALIZATION COMPANIES RISK. Large capitalization companies may be less able than smaller capitalization companies to adapt to changing market conditions. Large capitalization companies may be more mature and subject to more limited growth potential compared with smaller capitalization companies. During different market cycles, the performance of large capitalization companies has trailed the overall performance of the broader securities markets.

 

UNITED STATES RISK. Certain changes in the U.S. economy, such as when the U.S. economy weakens or when its financial markets decline, may have an adverse effect on the securities to which the Fund has exposure.

NON-DIVERSIFICATION RISK. As a “non-diversified” fund, the Fund may hold a smaller number of portfolio securities than many other funds. To the extent the Fund invests in a relatively small number of issuers, a decline in the market value of a particular security held by the Fund may affect its value more than if it invested in a larger number of issuers. The value of the Fund Shares may be more volatile than the values of shares of more diversified funds.

Roundhill ARM WeeklyPay™ ETF | MARKET RISK  
Prospectus [Line Items]  
Risk [Text Block]

MARKET RISK. Market risk is the risk that a particular investment, or Fund Shares in general, may fall in value. Securities are subject to market fluctuations caused by real or perceived adverse economic, political, and regulatory factors or market developments, changes in interest rates, disruptions to trade, impositions of tariffs and perceived trends in securities prices. Fund Shares could decline in value or underperform other investments. In addition, local, regional or global events such as war, acts of terrorism, market manipulation, government defaults, government shutdowns, regulatory actions, political changes, diplomatic developments, the imposition of sanctions and other similar measures, spread of infectious diseases or other public health issues, recessions, natural disasters, or other events could have a significant negative impact on the Fund and its investments. Any of such circumstances could have a materially negative impact on the value of Fund Shares, the liquidity of an investment, and may result in increased market volatility. During any such events, Fund Shares may trade at increased premiums or discounts to their net asset value, the bid/ask spread on Fund Shares may widen and the returns on investment may fluctuate.

Roundhill ARM WeeklyPay™ ETF | LIQUIDITY RISK  
Prospectus [Line Items]  
Risk [Text Block]

LIQUIDITY RISK. The market for swap agreements that reference ARM shares may be subject to periods of illiquidity. During such times it may be difficult or impossible to buy or sell a position at the desired price. Market disruptions or volatility can also make it difficult to find a counterparty willing to transact at a reasonable price and sufficient size. Illiquid markets may cause losses, which could be significant. The large size of the positions which the Fund may acquire increases the risk of illiquidity, may make its positions more difficult to liquidate, and may increase the losses incurred while trying to do so. Such large positions also may impact the price of swap agreements on ARM shares.

Roundhill ARM WeeklyPay™ ETF | ACTIVE MANAGEMENT RISK

Risk [Text Block]

ACTIVE MANAGEMENT RISK. The Fund is actively-managed and its performance reflects investment decisions that the Adviser and/or Sub-Adviser makes for the Fund. Such judgments about the Fund’s investments may prove to be incorrect. If the investments selected and the strategies employed by the Fund fail to produce the intended results, the Fund could underperform as compared to other funds with similar investment objectives and/or strategies, or could have negative returns.

Roundhill ARM WeeklyPay™ ETF | ACTIVE MARKET RISK  
Prospectus [Line Items]  
Risk [Text Block]

ACTIVE MARKET RISK. Although Fund Shares are listed for trading on the Exchange, there can be no assurance that an active trading market for Fund Shares will develop or be maintained. Fund Shares trade on the Exchange at market prices that may be below, at or above the Fund’s net asset value. Securities, including Fund Shares, are subject to market fluctuations and liquidity constraints that may be caused by such factors as economic, political, or regulatory developments, changes in interest rates, and/or perceived trends in securities prices. Fund Shares could decline in value or underperform other investments.

Risk [Text Block]

CONCENTRATION RISK. The Fund is susceptible to an increased risk of loss, including losses due to adverse events that affect the Fund’s investments more than the market as a whole, to the extent that the Fund’s investments are concentrated in investments that provide exposure to ARM and the industry to which it is assigned.

Roundhill ARM WeeklyPay™ ETF | COUNTERPARTY RISK  
Prospectus [Line Items]  
Risk [Text Block]

COUNTERPARTY RISK. Fund transactions involving a counterparty are subject to the risk that the counterparty will not fulfill its obligation to the Fund. Counterparty risk may arise because of the counterparty’s financial condition (i.e., financial difficulties, bankruptcy, or insolvency), market activities and developments, or other reasons, whether foreseen or not. A counterparty’s inability to fulfill its obligation may result in significant financial loss to the Fund. The Fund may be unable to recover its investment from the counterparty or may obtain a limited recovery, and/or recovery may be delayed.

CREDIT RISK. An issuer or other obligated party of a debt security may be unable or unwilling to make dividend, interest and/or principal payments when due. In addition, the value of a debt security may decline because of concerns about the issuer’s ability or unwillingness to make such payments.

Roundhill ARM WeeklyPay™ ETF | CURRENT MARKET CONDITIONS RISK  
Prospectus [Line Items]  
Risk [Text Block]

CURRENT MARKET CONDITIONS RISK. Current market conditions risk is the risk that a particular investment, or Fund Shares in general, may fall in value due to current market conditions. As a means to fight inflation, which remains at elevated levels, the Federal Reserve and certain foreign central banks have raised interest rates; however, the Federal Reserve has recently lowered interest rates and may continue to do so. U.S. regulators have proposed several changes to market and issuer regulations which would directly impact the Fund, and any regulatory changes could adversely impact the Fund’s ability to achieve its investment strategies or make certain investments. Recent and potential future bank failures could result in disruption to the broader banking industry or markets generally and reduce confidence in financial institutions and the economy as a whole, which may also heighten market volatility and reduce liquidity. Additionally, challenges in commercial real estate markets, including rising interest rates, declining valuations and increasing vacancies, could have a broader impact on financial markets. The ongoing adversarial political climate in the United States, as well as political and diplomatic events both domestic and abroad, have and may continue to have an adverse impact the U.S. regulatory landscape, markets and investor behavior, which could have a negative impact on the Fund’s investments and operations. The change in administration resulting from the 2024 United States national elections could result in significant impacts to international trade relations, tax and immigration policies, and other aspects of the national and international political and financial landscape, which could affect, among other things, inflation and the securities markets generally. Other unexpected political, regulatory and diplomatic events within the U.S. and abroad may affect investor and consumer confidence and may adversely impact financial markets and the broader economy. For example, ongoing armed conflicts between Russia and Ukraine in Europe and among Israel, Iran, Hamas and other militant groups in the Middle East, have caused and could continue to cause significant market disruptions and volatility within the markets in Russia, Europe, the Middle East and the United States. The hostilities and sanctions resulting from those hostilities have and could continue to have a significant impact on certain Fund investments as well as Fund performance and liquidity. The economies of the United States and its trading partners, as well as the financial markets generally, may be adversely impacted by trade disputes, including the imposition of tariffs, and other matters. For example, the United States has imposed trade barriers and restrictions on China. In addition, the Chinese government is engaged in a longstanding dispute with Taiwan, continually threatening an invasion. If the political climate between the United States and China does not improve or continues to deteriorate, if China were to attempt invading Taiwan, or if other geopolitical conflicts develop or worsen, economies, markets and individual securities may be adversely affected, and the value of the Fund’s assets may go down. A public health crisis and the ensuing policies enacted by governments and central banks may cause significant volatility and uncertainty in global financial markets, negatively impacting global growth prospects. As the COVID-19 global pandemic illustrated, such events may affect certain geographic regions, countries, sectors and industries more significantly than others. Advancements in technology may also adversely impact markets and the overall performance of the Fund. For instance, the economy may be significantly impacted by the advanced development and increased regulation of artificial intelligence. Additionally, cyber security breaches of both government and non-government entities could have negative impacts on infrastructure and the ability of such entities, including the Fund, to operate properly. These events, and any other future events, may adversely affect the prices and liquidity of the Fund’s portfolio investments and could result in disruptions in the trading markets.

Roundhill ARM WeeklyPay™ ETF | CYBERSECURITY RISK  
Prospectus [Line Items]  
Risk [Text Block]

CYBERSECURITY RISK. Failures or breaches of the electronic systems of the Fund, the Fund’s adviser, sub-adviser, distributor and other service providers, market makers, Authorized Participants or the issuers of securities in which the Fund invests have the ability to cause disruptions, negatively impact the Fund’s business operations and/or potentially result in financial losses to the Fund and its shareholders. While the Fund has established business continuity plans and risk management systems seeking to address system breaches or failures, there are inherent limitations in such plans and systems. Furthermore, the Fund cannot control the cybersecurity plans and systems of the Fund’s other service providers, market makers, Authorized Participants or issuers of securities in which the Fund invests.

Roundhill ARM WeeklyPay™ ETF | DEBT SECURITIES RISK  
Prospectus [Line Items]  
Risk [Text Block]

DEBT SECURITIES RISK. Investments in debt securities subject the holder to the credit risk of the issuer. Credit risk refers to the possibility that the issuer or other obligor of a security will not be able or willing to make payments of interest and principal when due. Generally, the value of debt securities will change inversely with changes in interest rates. To the extent that interest rates rise, certain underlying obligations may be paid off substantially slower than originally anticipated and the value of those securities may fall sharply. During periods of falling interest rates, the income received by the Fund may decline. If the principal on a debt security is prepaid before expected, the prepayments of principal may have to be reinvested in obligations paying interest at lower rates. Debt securities generally do not trade on a securities exchange making them generally less liquid and more difficult to value than common stock.

Roundhill ARM WeeklyPay™ ETF | DERIVATIVES RISK  
Prospectus [Line Items]  
Risk [Text Block]

DERIVATIVES RISK. The use of derivative instruments involves risks different from, or possibly greater than, the risks associated with investing directly in securities and other traditional investments. These risks include: (i) the risk that the counterparty to a derivative transaction may not fulfill its contractual obligations; (ii) risk of mispricing or improper valuation; and (iii) the risk that changes in the value of the derivative may not correlate perfectly with the underlying asset. Derivative prices are highly volatile and may fluctuate substantially during a short period of time. Such prices are influenced by numerous factors that affect the markets, including, but not limited to: changing supply and demand relationships; government programs and policies; national and international political and economic events, changes in interest rates, inflation and deflation and changes in supply and demand relationships. Trading derivative instruments involves risks different from, or possibly greater than, the risks associated with investing directly in securities. Derivative contracts ordinarily have leverage inherent in their terms. The use of leverage may cause the Fund to liquidate portfolio positions when it would not be advantageous to do so in order to satisfy its obligations or to meet regulatory or contractual requirements for derivatives. The use of derivatives can magnify potential for gain or loss and, therefore, amplify the effects of market volatility on share price.

Roundhill ARM WeeklyPay™ ETF | DISTRIBUTION TAX RISK  
Prospectus [Line Items]  
Risk [Text Block]

DISTRIBUTION TAX RISK. The Fund currently expects to make distributions on a weekly basis. Such frequent distributions may expose investors to increased tax liabilities. However, these distributions may exceed the Fund’s income and gains for the Fund’s taxable year. Distributions in excess of the Fund’s current and accumulated earnings and profits will be treated as a return of capital. A return of capital distribution generally will not be taxable but will reduce the shareholder’s cost basis and will result in a higher capital gain or lower capital loss when those Fund Shares on which the distribution was received are sold. Once a Fund shareholder’s cost basis is reduced to zero, further distributions will be treated as capital gain if the Fund shareholder holds Fund Shares as capital assets. Additionally, any capital returned through distributions will be distributed after payment of Fund fees and expenses. Because a portion of the Fund’s distributions may consist of return of capital, the Fund may not be an appropriate investment for investors who do not want their principal investment in the Fund to decrease over time or who do not wish to receive return of capital in a given period. In the event that a shareholder purchases Fund Shares shortly before a distribution by the Fund, the entire distribution may be taxable to the shareholder even though a portion of the distribution effectively represents a return of the purchase price.

Roundhill ARM WeeklyPay™ ETF | ETF RISK  
Prospectus [Line Items]  
Risk [Text Block]

ETF RISK. The Fund may invest in ETFs. The value of an ETF held by the Fund will fluctuate over time based on fluctuations in the values of the assets held by the ETF, which may be affected by changes in general economic conditions, expectations for future growth and profits, interest rates and the supply and demand for those assets. When the Fund invests in an ETF, it will bear a proportionate share of the ETF’s expenses. Brokerage, tax and other expenses may negatively impact the performance of the ETF and, in turn, the value of the Fund Shares. An ETF that tracks an index may not exactly match the performance of the index due to cash drag, differences between the portfolio of the ETF and the components of the index, expenses and other factors.

Roundhill ARM WeeklyPay™ ETF | INFLATION RISK  
Prospectus [Line Items]  
Risk [Text Block]

INFLATION RISK. Inflation risk is the risk that the value of assets or income from investments will be less in the future as inflation decreases the value of money. As inflation increases, the present value of the Fund’s assets and distributions may decline. This risk is more prevalent with respect to fixed income securities held by the Fund.

Roundhill ARM WeeklyPay™ ETF | Interest Rate Risk [Member]  
Prospectus [Line Items]  
Risk [Text Block]

INTEREST RATE RISK. Interest rate risk is the risk that the value of the debt securities in the Fund’s portfolio will decline because of rising market interest rates. Interest rate risk is generally lower for shorter term debt securities and higher for longer-term debt securities. Duration is a reasonably accurate measure of a debt security’s price sensitivity to changes in interest rates and a common measure of interest rate risk. Duration measures a debt security’s expected life on a present value basis, taking into account the debt security’s yield, interest payments and final maturity. In general, duration represents the expected percentage change in the value of a security for an immediate 1% change in interest rates. For example, the price of a debt security with a three-year duration would be expected to drop by approximately 3% in response to a 1% increase in interest rates. Therefore, prices of debt securities with shorter durations tend to be less sensitive to interest rate changes than debt securities with longer durations. As the value of a debt security changes over time, so will its duration.

Roundhill ARM WeeklyPay™ ETF | LEGISLATION AND LITIGATION RISK  
Prospectus [Line Items]  
Risk [Text Block]

LEGISLATION AND LITIGATION RISK. Legislation or litigation that affects the value of assets or securities held by the Fund may reduce the value of the Fund. From time to time, various legislative initiatives are proposed that may have a negative impact on certain assets or securities in which the Fund invests. In addition, litigation regarding any of the assets or securities owned by the Fund may negatively impact the value of the Shares. Such legislation or litigation may cause the Fund to lose value or may result in higher portfolio turnover if the Adviser determines to sell such a holding.

Roundhill ARM WeeklyPay™ ETF | LEVERAGE RISK  
Prospectus [Line Items]  
Risk [Text Block]

LEVERAGE RISK. The Fund obtains investment exposure in excess of its net assets by utilizing leverage and may lose more money in market conditions that are adverse to its investment objectives than a fund that does not utilize leverage. An investment in the Fund is exposed to the risk that a decline in the weekly performance of shares of ARM will be magnified. This means that an investment in the Fund will be reduced by an amount equal to 1.2% for every 1% weekly decline in the market value of the ARM shares, not including the costs of financing leverage and other operating expenses, which would further reduce its value. The Fund could theoretically lose an amount greater than its net assets in the event the market value of ARM shares decline more than 83.33% over a calendar week. Leverage will also have the effect of magnifying any differences in the Fund’s correlation with ARM shares.

Roundhill ARM WeeklyPay™ ETF | MONEY MARKET INSTRUMENTS RISK  
Prospectus [Line Items]  
Risk [Text Block]

MONEY MARKET INSTRUMENTS RISK. The value of money market instruments may be affected by changing interest rates and by changes in the credit ratings of the investments. If a significant amount of the Fund’s assets are invested in money market instruments, it will be more difficult for the Fund to achieve its investment objectives. An investment in a money market fund is not insured or guaranteed by the FDIC or any other government agency. It is possible to lose money by investing in a money market fund.

Roundhill ARM WeeklyPay™ ETF | OPERATIONAL RISK  
Prospectus [Line Items]  
Risk [Text Block]

OPERATIONAL RISK. The Fund is subject to risks arising from various operational factors, including, but not limited to, human error, processing and communication errors, errors of the Fund’s service providers, counterparties or other third-parties, failed or inadequate processes and technology or systems failures. The Fund relies on third-parties for a range of services, including custody. Any delay or failure relating to engaging or maintaining such service providers may affect the Fund’s ability to meet its investment objectives. Although the Fund and the Adviser seek to reduce these operational risks through controls and procedures, there is no way to completely protect against such risks.

Roundhill ARM WeeklyPay™ ETF | SPECIAL TAX RISK  
Prospectus [Line Items]  
Risk [Text Block]

SPECIAL TAX RISK. The Fund intends to qualify annually and to elect to be treated as a regulated investment company under the Internal Revenue Code of 1986, as amended (the “Code”). To qualify for the favorable U.S. federal income tax treatment generally accorded to regulated investment companies, the Fund must, among other things, (i) derive in each taxable year at least 90% of its gross income from dividends, interest, payments with respect to securities loans and gains from the sale or other disposition of stock, securities or foreign currencies or other income derived with respect to its business of investing in such stock, securities or currencies, or net income derived from interests in certain publicly traded partnerships; (ii) diversify its holdings so that, at the end of each quarter of the taxable year, (a) at least 50% of the market value of the Fund’s assets is represented by cash and cash items (including receivables), U.S. government securities, the securities of other regulated investment companies and other securities, with such other securities of any one issuer generally limited for the purposes of this calculation to an amount not greater than 5% of the value of the Fund’s total assets and not greater than 10% of the outstanding voting securities of such issuer, and (b) not more than 25% of the value of its total assets is invested in the securities (other than U.S. government securities or the securities of other regulated investment companies) of any one issuer, or two or more issuers which the Fund controls which are engaged in the same, similar or related trades or businesses, or the securities of one or more of certain publicly traded partnerships; and (iii) distribute at least 90% of its investment company taxable income (which includes, among other items, dividends, interest and net short-term capital gains in excess of net long-term capital losses) and at least 90% of its net tax-exempt interest income each taxable year. There are certain exceptions for failure to qualify if the failure is for reasonable cause or is de minimis, and certain corrective action is taken and certain tax payments are made by the Fund.

 

The authority with regard to swaps entered into by regulated investment companies is unclear both as to the qualification under the income test and the identification of the issuer under the diversification test. The Fund intends to take the position that because the swaps held by the Fund reference securities that the income on the swaps are “other income” from the Fund’s business of investing in stocks and securities. In addition, the Fund intends to manage its investments in the swaps so that neither the exposure to issuer of the referenced security nor the exposure to any one counterparty of the swaps will exceed 25% of the gross value of the Fund’s portfolio at the end of any quarter.

 

If the Fund were to fail to meet the qualifying income test or asset diversification test and fail to qualify as a RIC, it would be taxed in the same manner as an ordinary corporation, and distributions to its shareholders would not be deductible by the Fund in computing its taxable income, which would adversely affect the Fund’s performance.

Roundhill ARM WeeklyPay™ ETF | STRUCTURAL ETF RISKS  
Prospectus [Line Items]  
Risk [Text Block]

STRUCTURAL ETF RISKS. The Fund is an ETF. Accordingly, it is subject to certain risks associated with its unique structure.

 

Market Participants Risk. Only an Authorized Participant may engage in creation or redemption transactions directly with the Fund, and none of those Authorized Participants is obligated to engage in creation and/or redemption transactions. The Fund has a limited number of institutions that may act as Authorized Participants on an agency basis (i.e., on behalf of other market participants). To the extent that Authorized Participants exit the business or are unable to proceed with creation or redemption orders with respect to the Fund and no other Authorized Participant is able to step forward to create or redeem, Fund Shares may be more likely to trade at a premium or discount to NAV and possibly face trading halts or delisting. The Fund may also rely on a small number of third-party market makers to provide a market for the purchase and sale of Fund Shares but such market makers are under no obligation to do so. Decisions by Authorized Participants or market makers to reduce their role or step away from these activities in times of market stress could inhibit the effectiveness of the arbitrage process in maintaining the relationship between the underlying values of the Fund’s portfolio securities and the Fund’s market price. Any trading halt or other problem relating to the trading activity of these market makers or any issues disrupting the Authorized Participants’ ability to proceed with creation and/or redemption orders could result in a dramatic change in the spread between the Fund’s net asset value and the price at which Fund Shares are trading on the Exchange, which could result in a decrease in value of Fund Shares. This reduced effectiveness could result in Fund Shares trading at a premium or discount to net asset value and also in greater than normal intraday bid-ask spreads Fund Shares.

 

Cash Transactions Risk. The Fund currently expects to effect a significant portion of its creations and redemptions for cash, rather than in-kind securities. Paying redemption proceeds in cash rather than through in-kind delivery of portfolio securities may require the Fund to dispose of or sell portfolio securities or other assets at an inopportune time to obtain the cash needed to meet redemption orders. This may cause the Fund to sell a security and recognize a capital gain or loss that might not have been incurred if it had made a redemption in-kind. As a result, the Fund may pay out higher or lower annual capital gains distributions than ETFs that redeem in-kind. The use of cash creations and redemptions may also cause the Fund’s Shares to trade in the market at greater bid-ask spreads or greater premiums or discounts to the Fund’s NAV. Furthermore, the Fund may not be able to execute cash transactions for creation and redemption purposes at the same price used to determine the Fund’s NAV. To the extent that the maximum additional charge for creation or redemption transactions is insufficient to cover the execution shortfall, the Fund’s performance could be negatively impacted.

 

Costs of Buying and Selling Fund Shares. Due to the costs of buying or selling Fund Shares, including brokerage commissions imposed by brokers and bid/ask spreads, frequent trading of Fund Shares may significantly reduce investment results and an investment in Fund Shares may not be advisable for investors who anticipate regularly making small investments.

 

Premium/Discount Risk. As with all ETFs, Fund Shares may be bought and sold in the secondary market at market prices. The trading prices of Fund Shares in the secondary market may differ from the Fund’s daily net asset value per share and there may be times when the market price of the shares is more than the net asset value per share (premium) or less than the net asset value per share (discount). If a shareholder purchases Fund Shares at a time when the market price is at a premium to the net asset value or sells Fund Shares at a time when the market price is at a discount to the net asset value, the shareholder may pay more for, or receive less than, the underlying value of the Fund Shares, respectively. This risk is heightened in times of market volatility or periods of steep market declines.

 

Trading Risks. Although Fund Shares are listed for trading on the Exchange and may be traded on U.S. exchanges other than the Exchange, there can be no assurance that Fund Shares will trade with any volume, or at all, on any stock exchange. In stressed market conditions, the liquidity of Fund Shares may begin to mirror the liquidity of the Fund’s underlying portfolio holdings, which can be significantly less liquid than Fund Shares. Trading in Fund Shares on the Exchange may be halted due to market conditions or for reasons that, in the view of the Exchange, make trading in Fund Shares inadvisable. In addition, trading in Fund Shares on the Exchange is subject to trading halts caused by extraordinary market volatility pursuant to the Exchange’s “circuit breaker” rules. There can be no assurance that the requirements of the Exchange necessary to maintain the listing of the Fund will continue to be met or will remain unchanged.

Roundhill ARM WeeklyPay™ ETF | U.S. GOVERNMENT SECURITIES RISK  
Prospectus [Line Items]  
Risk [Text Block]

U.S. GOVERNMENT SECURITIES RISK. U.S. government securities are subject to interest rate risk but generally do not involve the credit risks associated with investments in other types of debt securities. As a result, the yields available from U.S. government securities are generally lower than the yields available from other debt securities. U.S. government securities are guaranteed only as to the timely payment of interest and the payment of principal when held to maturity.

Roundhill ARM WeeklyPay™ ETF | VALUATION RISK  
Prospectus [Line Items]  
Risk [Text Block]

VALUATION RISK. The Fund may hold securities or other assets that may be valued on the basis of factors other than market quotations. This may occur because the asset or security does not trade on a centralized exchange, or in times of market turmoil or reduced liquidity. There are multiple methods that can be used to value a portfolio holding when market quotations are not readily available. The value established for any portfolio holding at a point in time might differ from what would be produced using a different methodology or if it had been priced using market quotations. Portfolio holdings that are valued using techniques other than market quotations, including “fair valued” assets or securities, may be subject to greater fluctuation in their valuations from one day to the next than if market quotations were used. In addition, there is no assurance that the Fund could sell or close out a portfolio position for the value established for it at any time, and it is possible that the Fund would incur a loss because a portfolio position is sold or closed out at a discount to the valuation established by the Fund at that time. The Fund’s ability to value investments may be impacted by technological issues or errors by pricing services or other third-party service providers.

Roundhill ARM WeeklyPay™ ETF | EQUITY SECURITIES RISK  
Prospectus [Line Items]  
Risk [Text Block]

EQUITY SECURITIES RISK. Equity securities are subject to changes in value, and their values may be more volatile than those of other asset classes. Equity securities prices fluctuate for several reasons, including changes in investors’ perceptions of the financial condition of an issuer or the general condition of the relevant equity market, such as market volatility, or when political or economic events affecting an issuer occur. Common stock prices may be particularly sensitive to rising interest rates, as the cost of capital rises and borrowing costs increase. Common stocks generally subject their holders to more risks than preferred stocks and debt securities because common stockholders’ claims are subordinated to those of holders of preferred stocks and debt securities upon the bankruptcy of the issuer.

Roundhill ARM WeeklyPay™ ETF | SWAP AGREEMENTS RISK  
Prospectus [Line Items]  
Risk [Text Block]

SWAP AGREEMENTS RISK. The Fund will utilize swap agreements to derive its exposure to shares of ARM. Swap agreements may involve greater risks than direct investment in securities as they may be leveraged and are subject to credit risk, counterparty risk and valuation risk. A swap agreement could result in losses if the underlying reference or asset does not perform as anticipated. In addition, many swaps trade over-the-counter and may be considered illiquid. It may not be possible for the Fund to liquidate a swap position at an advantageous time or price, which may result in significant losses.

Roundhill ARM WeeklyPay™ ETF | REGULATED INVESTMENT COMPANY TAX RISKS  
Prospectus [Line Items]  
Risk [Text Block]

REGULATED INVESTMENT COMPANY TAX RISKS. The Fund intends to qualify annually and to elect to be treated as a regulated investment company under the Internal Revenue Code of 1986, as amended (the “Code”). To qualify for the favorable U.S. federal income tax treatment generally accorded to regulated investment companies, the Fund must, among other things, (i) derive in each taxable year at least 90% of its gross income from dividends, interest, payments with respect to securities loans and gains from the sale or other disposition of stock, securities or foreign currencies or other income derived with respect to its business of investing in such stock, securities or currencies, or net income derived from interests in certain publicly traded partnerships; (ii) diversify its holdings so that, at the end of each quarter of the taxable year, (a) at least 50% of the market value of the Fund’s assets is represented by cash and cash items (including receivables), U.S. government securities, the securities of other regulated investment companies and other securities, with such other securities of any one issuer generally limited for the purposes of this calculation to an amount not greater than 5% of the value of the Fund’s total assets and not greater than 10% of the outstanding voting securities of such issuer, and (b) not more than 25% of the value of its total assets is invested in the securities (other than U.S. government securities or the securities of other regulated investment companies) of any one issuer, or two or more issuers which the Fund controls which are engaged in the same, similar or related trades or businesses, or the securities of one or more of certain publicly traded partnerships; and (iii) distribute at least 90% of its investment company taxable income (which includes, among other items, dividends, interest and net short-term capital gains in excess of net long-term capital losses) and at least 90% of its net tax-exempt interest income each taxable year. There are certain exceptions for failure to qualify if the failure is for reasonable cause or is de minimis, and certain corrective action is taken and certain tax payments are made by the Fund.

 

If the Fund were to fail to meet the qualifying income test or asset diversification test and fail to qualify as a RIC, it would be taxed in the same manner as an ordinary corporation, and distributions to its shareholders would not be deductible by the Fund in computing its taxable income, which would adversely affect the Fund’s performance.

Roundhill ARM WeeklyPay™ ETF | LARGE SHAREHOLDER RISK  
Prospectus [Line Items]  
Risk [Text Block]

LARGE SHAREHOLDER RISK. Certain shareholders, including affiliated funds advised by the Adviser, may from time to time own a significant portion of the Fund’s shares. In addition, a third-party investor, the Adviser or an affiliate of the Adviser (“Affiliate”), an authorized participant, a market maker, or another entity may invest in the Fund and hold its investment for a limited period solely to facilitate the commencement of the Fund or to help the Fund achieve a specified size or scale. There can be no assurance that any large shareholder will not redeem its investment, that the size of the Fund will be maintained at such levels, or that the Fund will continue to meet applicable listing requirements. Redemptions by large shareholders could have a significant negative impact on the Fund. In addition, transactions by large shareholders may account for a large percentage of the trading volume on the Fund’s listing exchange and may, therefore, have a material upward or downward effect on the market price of the shares.

 

To the extent that a significant percentage of the Fund’s shares are owned or controlled by a small number of account shareholders (or a single account shareholder), including funds or accounts over which the Adviser or an Affiliate has investment discretion, the Fund is subject to the risk that those shareholders may purchase or redeem Fund shares in significant amounts rapidly or unexpectedly, including as a result of an asset allocation decision made by the Adviser or an Affiliate. This may adversely affect the Fund’s performance if the Adviser is forced to sell portfolio securities or invest cash when it would not otherwise choose to do so. Redemptions of a large number of shares may affect the liquidity of the Fund’s portfolio, increase the Fund’s transaction costs, and accelerate the realization of taxable income and/or gains. In addition, a large redemption could result in the Fund’s current expenses being allocated over a smaller asset base, leading to an increase in the Fund’s gross expense ratio. Large purchases of the Fund’s shares may also adversely affect the Fund’s performance to the extent that the Fund is delayed in investing new cash or otherwise maintains a larger cash position than it ordinarily would, particularly if the Fund accepts cash for an order for the purchase of creation units of the Fund’s shares.

Roundhill ARM WeeklyPay™ ETF | ARM INVESTING RISKS  
Prospectus [Line Items]  
Risk [Text Block]

ARM INVESTING RISKS. The Fund will have significant exposure to ARM through its investments in swap agreements that utilize ARM as the reference asset. Accordingly, the Fund will subject to the risks of ARM, set forth below.

 

ARM ISSUER-SPECIFIC RISKS. Issuer-specific attributes may cause an investment held by the Fund to be more volatile than the market generally. The value of an individual security or particular type of security may be more volatile than the market as a whole and may perform differently from the value of the market as a whole. ARM operates in the highly competitive semiconductor industry, where rapid technological innovation and shifting market dynamics can significantly impact its business. The company’s licensing-based revenue model relies on its ability to maintain a competitive edge in chip design, particularly in central processing units (CPUs), graphics processing units (GPUs), and artificial intelligence (AI) accelerators. Any loss of market share to competing architectures could negatively affect revenue and profitability. Unlike other semiconductor companies, ARM primarily generates revenue through licensing fees and royalties from semiconductor manufacturers. A decline in demand for ARM-based designs, reductions in royalty rates, or changes in customer relationships could materially impact ARM’s earnings. A significant portion of ARM’s revenue from this model is derived from a few major customers. Any deterioration in these relationships, whether due to strategic shifts, legal disputes, or competitive developments, could lead to revenue losses. Additionally, major chipmakers could develop in-house architectures to reduce reliance on ARM’s designs. ARM designs semiconductors but does not manufacture them, relying heavily on third-party foundries, particularly Taiwan Semiconductor Manufacturing Company (TSMC) and Samsung. Geopolitical tensions between the U.S., China and Taiwan could disrupt ARM’s supply chain, increasing costs or limiting access to key manufacturing partners. Additionally, export controls or sanctions targeting ARM’s technology could hinder its ability to do business in certain regions. ARM has faced scrutiny from global regulators, especially after its attempted acquisition by Nvidia was blocked due to antitrust concerns. As ARM expands its presence in AI, cloud computing, and automotive semiconductors, it could face additional regulatory hurdles and litigation related to intellectual property rights, antitrust laws and data security. ARM’s revenue is heavily reliant on licensing and royalty fees from customers in North America, Asia, and Europe, which are often denominated in U.S. dollars and other foreign currencies. However, many of ARM’s operational costs, including employee salaries, research and development expenses, and corporate overheads, are incurred in GBP. A stronger GBP relative to the U.S. dollar and other currencies could lead to reduced profitability by making ARM’s products more expensive for international customers while increasing the relative cost of GBP-denominated expenses.

 

ASIAN GEOPOLITICAL TENSIONS RISK. ARM has significant exposure to Asia as a result of its operations, supply chain and location of its customers. Asian geopolitical developments, such as trade disputes, territorial conflicts, regulatory changes, sanctions, military actions, or changes in diplomatic relations, could materially impact ARM’s business operations, financial performance and stock price. Tensions between major economies in the region, including but not limited to China, Taiwan, South Korea, Japan and India, as well as broader U.S.-Asia relations, may lead to increased market volatility, disruptions in trade, supply chain constraints, or restrictions on capital flows. Governments in these regions may impose tariffs, export controls, or other regulatory measures that could negatively affect certain industries, including technology, manufacturing, and consumer goods. Additionally, political instability, social unrest, or unexpected policy shifts could create further uncertainty for businesses operating in the region.

 

INDIRECT INVESTMENT RISK. Arm Holdings plc is not affiliated with the Trust, the Fund, the Adviser, the Sub-Adviser or any affiliates thereof and is not involved with this offering in any way, and has no obligation to consider the Fund in taking any corporate actions that might affect the value of the Fund. The Trust, the Fund, the Adviser, the Sub-Adviser or any affiliate are not responsible for the performance of ARM and make no representation as to the performance of ARM. Investing in the Fund is not equivalent to investing in ARM. Fund shareholders will not have voting rights or rights to receive dividends or other distributions or any other rights with respect to ARM.

 

INFORMATION TECHNOLOGY COMPANIES RISK. Information technology companies face intense competition, both domestically and internationally, which may have an adverse effect on profit margins. Like other technology companies, information technology companies may have limited product lines, markets, financial resources or personnel. The products of information technology companies may face obsolescence due to rapid technological developments, frequent new product introduction, unpredictable changes in growth rates and competition for the services of qualified personnel. Companies in the information technology sector are heavily dependent on patent and intellectual property rights. The loss or impairment of these rights may adversely affect the profitability of these companies. Information technology companies are facing increased government and regulatory scrutiny and may be subject to adverse government or regulatory action.

 

LARGE CAPITALIZATION COMPANIES RISK. Large capitalization companies may be less able than smaller capitalization companies to adapt to changing market conditions. Large capitalization companies may be more mature and subject to more limited growth potential compared with smaller capitalization companies. During different market cycles, the performance of large capitalization companies has trailed the overall performance of the broader securities markets.

 

NON-U.S. SECURITIES RISK. Non-U.S. securities are subject to higher volatility than securities of domestic issuers due to possible adverse political, social or economic developments, restrictions on foreign investment or exchange of securities, capital controls, lack of liquidity, currency exchange rates, excessive taxation, government seizure of assets, the imposition of sanctions by foreign governments, different legal or accounting standards, and less government supervision and regulation of securities exchanges in foreign countries.

 

SEMICONDUCTOR COMPANIES RISK. Semiconductor companies face intense competition, both domestically and internationally, and such competition may have an adverse effect on profit margins. Semiconductor companies may have limited product lines, markets, financial resources or personnel. Semiconductor companies’ supply chain and operations are dependent on the availability of materials that meet exacting standards and the use of third parties to provide components and services. Semiconductor companies may rely on a limited number of suppliers, or upon suppliers in a single location, for certain materials, equipment or tools. Finding and qualifying alternate or additional suppliers can be a lengthy process that can cause production delays or impose unforeseen costs, and such alternatives may not be available at all. Production can be disrupted by the unavailability of resources, such as water, silicon, electricity, gases and other materials. Suppliers may also increase prices or encounter cybersecurity or other issues that can disrupt production or increase production costs. The products of semiconductor companies may face obsolescence due to rapid technological developments and frequent new product introduction, unpredictable changes in growth rates and competition for the services of qualified personnel. Capital equipment expenditures could be substantial, and equipment generally suffers from rapid obsolescence. Companies in the semiconductor industry are heavily dependent on patent and intellectual property rights. The loss or impairment of these rights, would adversely affect the profitability of these companies.

NON-DIVERSIFICATION RISK. As a “non-diversified” fund, the Fund may hold a smaller number of portfolio securities than many other funds. To the extent the Fund invests in a relatively small number of issuers, a decline in the market value of a particular security held by the Fund may affect its value more than if it invested in a larger number of issuers. The value of the Fund Shares may be more volatile than the values of shares of more diversified funds.

Roundhill AVGO WeeklyPay™ ETF | MARKET RISK  
Prospectus [Line Items]  
Risk [Text Block]

MARKET RISK. Market risk is the risk that a particular investment, or Fund Shares in general, may fall in value. Securities are subject to market fluctuations caused by real or perceived adverse economic, political, and regulatory factors or market developments, changes in interest rates, disruptions to trade, impositions of tariffs and perceived trends in securities prices. Fund Shares could decline in value or underperform other investments. In addition, local, regional or global events such as war, acts of terrorism, market manipulation, government defaults, government shutdowns, regulatory actions, political changes, diplomatic developments, the imposition of sanctions and other similar measures, spread of infectious diseases or other public health issues, recessions, natural disasters, or other events could have a significant negative impact on the Fund and its investments. Any of such circumstances could have a materially negative impact on the value of Fund Shares, the liquidity of an investment, and may result in increased market volatility. During any such events, Fund Shares may trade at increased premiums or discounts to their net asset value, the bid/ask spread on Fund Shares may widen and the returns on investment may fluctuate.

Roundhill AVGO WeeklyPay™ ETF | LIQUIDITY RISK  
Prospectus [Line Items]  
Risk [Text Block]

LIQUIDITY RISK. The market for swap agreements that reference AVGO shares may be subject to periods of illiquidity. During such times it may be difficult or impossible to buy or sell a position at the desired price. Market disruptions or volatility can also make it difficult to find a counterparty willing to transact at a reasonable price and sufficient size. Illiquid markets may cause losses, which could be significant. The large size of the positions which the Fund may acquire increases the risk of illiquidity, may make its positions more difficult to liquidate, and may increase the losses incurred while trying to do so. Such large positions also may impact the price of swap agreements on AVGO shares.

Roundhill AVGO WeeklyPay™ ETF | ACTIVE MANAGEMENT RISK

ACTIVE MANAGEMENT RISK. The Fund is actively-managed and its performance reflects investment decisions that the Adviser and/or Sub-Adviser makes for the Fund. Such judgments about the Fund’s investments may prove to be incorrect. If the investments selected and the strategies employed by the Fund fail to produce the intended results, the Fund could underperform as compared to other funds with similar investment objectives and/or strategies, or could have negative returns.

ACTIVE MARKET RISK. Although Fund Shares are listed for trading on the Exchange, there can be no assurance that an active trading market for Fund Shares will develop or be maintained. Fund Shares trade on the Exchange at market prices that may be below, at or above the Fund’s net asset value. Securities, including Fund Shares, are subject to market fluctuations and liquidity constraints that may be caused by such factors as economic, political, or regulatory developments, changes in interest rates, and/or perceived trends in securities prices. Fund Shares could decline in value or underperform other investments.

CONCENTRATION RISK. The Fund is susceptible to an increased risk of loss, including losses due to adverse events that affect the Fund’s investments more than the market as a whole, to the extent that the Fund’s investments are concentrated in investments that provide exposure to AVGO and the industry to which it is assigned.

Roundhill AVGO WeeklyPay™ ETF | COUNTERPARTY RISK

Risk [Text Block]

COUNTERPARTY RISK. Fund transactions involving a counterparty are subject to the risk that the counterparty will not fulfill its obligation to the Fund. Counterparty risk may arise because of the counterparty’s financial condition (i.e., financial difficulties, bankruptcy, or insolvency), market activities and developments, or other reasons, whether foreseen or not. A counterparty’s inability to fulfill its obligation may result in significant financial loss to the Fund. The Fund may be unable to recover its investment from the counterparty or may obtain a limited recovery, and/or recovery may be delayed.

Roundhill AVGO WeeklyPay™ ETF | CURRENT MARKET CONDITIONS RISK  
Prospectus [Line Items]  
Risk [Text Block]

CURRENT MARKET CONDITIONS RISK. Current market conditions risk is the risk that a particular investment, or Fund Shares in general, may fall in value due to current market conditions. As a means to fight inflation, which remains at elevated levels, the Federal Reserve and certain foreign central banks have raised interest rates; however, the Federal Reserve has recently lowered interest rates and may continue to do so. U.S. regulators have proposed several changes to market and issuer regulations which would directly impact the Fund, and any regulatory changes could adversely impact the Fund’s ability to achieve its investment strategies or make certain investments. Recent and potential future bank failures could result in disruption to the broader banking industry or markets generally and reduce confidence in financial institutions and the economy as a whole, which may also heighten market volatility and reduce liquidity. Additionally, challenges in commercial real estate markets, including rising interest rates, declining valuations and increasing vacancies, could have a broader impact on financial markets. The ongoing adversarial political climate in the United States, as well as political and diplomatic events both domestic and abroad, have and may continue to have an adverse impact the U.S. regulatory landscape, markets and investor behavior, which could have a negative impact on the Fund’s investments and operations. The change in administration resulting from the 2024 United States national elections could result in significant impacts to international trade relations, tax and immigration policies, and other aspects of the national and international political and financial landscape, which could affect, among other things, inflation and the securities markets generally. Other unexpected political, regulatory and diplomatic events within the U.S. and abroad may affect investor and consumer confidence and may adversely impact financial markets and the broader economy. For example, ongoing armed conflicts between Russia and Ukraine in Europe and among Israel, Iran, Hamas and other militant groups in the Middle East, have caused and could continue to cause significant market disruptions and volatility within the markets in Russia, Europe, the Middle East and the United States. The hostilities and sanctions resulting from those hostilities have and could continue to have a significant impact on certain Fund investments as well as Fund performance and liquidity. The economies of the United States and its trading partners, as well as the financial markets generally, may be adversely impacted by trade disputes, including the imposition of tariffs, and other matters. For example, the United States has imposed trade barriers and restrictions on China. In addition, the Chinese government is engaged in a longstanding dispute with Taiwan, continually threatening an invasion. If the political climate between the United States and China does not improve or continues to deteriorate, if China were to attempt invading Taiwan, or if other geopolitical conflicts develop or worsen, economies, markets and individual securities may be adversely affected, and the value of the Fund’s assets may go down. A public health crisis and the ensuing policies enacted by governments and central banks may cause significant volatility and uncertainty in global financial markets, negatively impacting global growth prospects. As the COVID-19 global pandemic illustrated, such events may affect certain geographic regions, countries, sectors and industries more significantly than others. Advancements in technology may also adversely impact markets and the overall performance of the Fund. For instance, the economy may be significantly impacted by the advanced development and increased regulation of artificial intelligence. Additionally, cyber security breaches of both government and non-government entities could have negative impacts on infrastructure and the ability of such entities, including the Fund, to operate properly. These events, and any other future events, may adversely affect the prices and liquidity of the Fund’s portfolio investments and could result in disruptions in the trading markets.

Roundhill AVGO WeeklyPay™ ETF | CYBERSECURITY RISK  
Prospectus [Line Items]  
Risk [Text Block]

CYBERSECURITY RISK. Failures or breaches of the electronic systems of the Fund, the Fund’s adviser, sub-adviser, distributor and other service providers, market makers, Authorized Participants or the issuers of securities in which the Fund invests have the ability to cause disruptions, negatively impact the Fund’s business operations and/or potentially result in financial losses to the Fund and its shareholders. While the Fund has established business continuity plans and risk management systems seeking to address system breaches or failures, there are inherent limitations in such plans and systems. Furthermore, the Fund cannot control the cybersecurity plans and systems of the Fund’s other service providers, market makers, Authorized Participants or issuers of securities in which the Fund invests.

Roundhill AVGO WeeklyPay™ ETF | DEBT SECURITIES RISK  
Prospectus [Line Items]  
Risk [Text Block]

DEBT SECURITIES RISK. Investments in debt securities subject the holder to the credit risk of the issuer. Credit risk refers to the possibility that the issuer or other obligor of a security will not be able or willing to make payments of interest and principal when due. Generally, the value of debt securities will change inversely with changes in interest rates. To the extent that interest rates rise, certain underlying obligations may be paid off substantially slower than originally anticipated and the value of those securities may fall sharply. During periods of falling interest rates, the income received by the Fund may decline. If the principal on a debt security is prepaid before expected, the prepayments of principal may have to be reinvested in obligations paying interest at lower rates. Debt securities generally do not trade on a securities exchange making them generally less liquid and more difficult to value than common stock.

Roundhill AVGO WeeklyPay™ ETF | DERIVATIVES RISK  
Prospectus [Line Items]  
Risk [Text Block]

DERIVATIVES RISK. The use of derivative instruments involves risks different from, or possibly greater than, the risks associated with investing directly in securities and other traditional investments. These risks include: (i) the risk that the counterparty to a derivative transaction may not fulfill its contractual obligations; (ii) risk of mispricing or improper valuation; and (iii) the risk that changes in the value of the derivative may not correlate perfectly with the underlying asset. Derivative prices are highly volatile and may fluctuate substantially during a short period of time. Such prices are influenced by numerous factors that affect the markets, including, but not limited to: changing supply and demand relationships; government programs and policies; national and international political and economic events, changes in interest rates, inflation and deflation and changes in supply and demand relationships. Trading derivative instruments involves risks different from, or possibly greater than, the risks associated with investing directly in securities. Derivative contracts ordinarily have leverage inherent in their terms. The use of leverage may cause the Fund to liquidate portfolio positions when it would not be advantageous to do so in order to satisfy its obligations or to meet regulatory or contractual requirements for derivatives. The use of derivatives can magnify potential for gain or loss and, therefore, amplify the effects of market volatility on share price.

Roundhill AVGO WeeklyPay™ ETF | DISTRIBUTION TAX RISK  
Prospectus [Line Items]  
Risk [Text Block]

DISTRIBUTION TAX RISK. The Fund currently expects to make distributions on a weekly basis. Such frequent distributions may expose investors to increased tax liabilities. However, these distributions may exceed the Fund’s income and gains for the Fund’s taxable year. Distributions in excess of the Fund’s current and accumulated earnings and profits will be treated as a return of capital. A return of capital distribution generally will not be taxable but will reduce the shareholder’s cost basis and will result in a higher capital gain or lower capital loss when those Fund Shares on which the distribution was received are sold. Once a Fund shareholder’s cost basis is reduced to zero, further distributions will be treated as capital gain if the Fund shareholder holds Fund Shares as capital assets. Additionally, any capital returned through distributions will be distributed after payment of Fund fees and expenses. Because a portion of the Fund’s distributions may consist of return of capital, the Fund may not be an appropriate investment for investors who do not want their principal investment in the Fund to decrease over time or who do not wish to receive return of capital in a given period. In the event that a shareholder purchases Fund Shares shortly before a distribution by the Fund, the entire distribution may be taxable to the shareholder even though a portion of the distribution effectively represents a return of the purchase price.

Roundhill AVGO WeeklyPay™ ETF | ETF RISK  
Prospectus [Line Items]  
Risk [Text Block]

ETF RISK. The Fund may invest in ETFs. The value of an ETF held by the Fund will fluctuate over time based on fluctuations in the values of the assets held by the ETF, which may be affected by changes in general economic conditions, expectations for future growth and profits, interest rates and the supply and demand for those assets. When the Fund invests in an ETF, it will bear a proportionate share of the ETF’s expenses. Brokerage, tax and other expenses may negatively impact the performance of the ETF and, in turn, the value of the Fund Shares. An ETF that tracks an index may not exactly match the performance of the index due to cash drag, differences between the portfolio of the ETF and the components of the index, expenses and other factors.

Roundhill AVGO WeeklyPay™ ETF | INFLATION RISK  
Prospectus [Line Items]  
Risk [Text Block]

INFLATION RISK. Inflation risk is the risk that the value of assets or income from investments will be less in the future as inflation decreases the value of money. As inflation increases, the present value of the Fund’s assets and distributions may decline. This risk is more prevalent with respect to fixed income securities held by the Fund.

Roundhill AVGO WeeklyPay™ ETF | Interest Rate Risk [Member]  
Prospectus [Line Items]  
Risk [Text Block]

INTEREST RATE RISK. Interest rate risk is the risk that the value of the debt securities in the Fund’s portfolio will decline because of rising market interest rates. Interest rate risk is generally lower for shorter term debt securities and higher for longer-term debt securities. Duration is a reasonably accurate measure of a debt security’s price sensitivity to changes in interest rates and a common measure of interest rate risk. Duration measures a debt security’s expected life on a present value basis, taking into account the debt security’s yield, interest payments and final maturity. In general, duration represents the expected percentage change in the value of a security for an immediate 1% change in interest rates. For example, the price of a debt security with a three-year duration would be expected to drop by approximately 3% in response to a 1% increase in interest rates. Therefore, prices of debt securities with shorter durations tend to be less sensitive to interest rate changes than debt securities with longer durations. As the value of a debt security changes over time, so will its duration.

Roundhill AVGO WeeklyPay™ ETF | LEGISLATION AND LITIGATION RISK  
Prospectus [Line Items]  
Risk [Text Block]

LEGISLATION AND LITIGATION RISK. Legislation or litigation that affects the value of assets or securities held by the Fund may reduce the value of the Fund. From time to time, various legislative initiatives are proposed that may have a negative impact on certain assets or securities in which the Fund invests. In addition, litigation regarding any of the assets or securities owned by the Fund may negatively impact the value of the Shares. Such legislation or litigation may cause the Fund to lose value or may result in higher portfolio turnover if the Adviser determines to sell such a holding.

Roundhill AVGO WeeklyPay™ ETF | LEVERAGE RISK  
Prospectus [Line Items]  
Risk [Text Block]

LEVERAGE RISK. The Fund obtains investment exposure in excess of its net assets by utilizing leverage and may lose more money in market conditions that are adverse to its investment objectives than a fund that does not utilize leverage. An investment in the Fund is exposed to the risk that a decline in the weekly performance of shares of AVGO will be magnified. This means that an investment in the Fund will be reduced by an amount equal to 1.2% for every 1% weekly decline in the market value of the AVGO shares, not including the costs of financing leverage and other operating expenses, which would further reduce its value. The Fund could theoretically lose an amount greater than its net assets in the event the market value of AVGO shares decline more than 83.33% over a calendar week. Leverage will also have the effect of magnifying any differences in the Fund’s correlation with AVGO shares.

Roundhill AVGO WeeklyPay™ ETF | MONEY MARKET INSTRUMENTS RISK  
Prospectus [Line Items]  
Risk [Text Block]

MONEY MARKET INSTRUMENTS RISK. The value of money market instruments may be affected by changing interest rates and by changes in the credit ratings of the investments. If a significant amount of the Fund’s assets are invested in money market instruments, it will be more difficult for the Fund to achieve its investment objectives. An investment in a money market fund is not insured or guaranteed by the FDIC or any other government agency. It is possible to lose money by investing in a money market fund.

Roundhill AVGO WeeklyPay™ ETF | OPERATIONAL RISK  
Prospectus [Line Items]  
Risk [Text Block]

OPERATIONAL RISK. The Fund is subject to risks arising from various operational factors, including, but not limited to, human error, processing and communication errors, errors of the Fund’s service providers, counterparties or other third-parties, failed or inadequate processes and technology or systems failures. The Fund relies on third-parties for a range of services, including custody. Any delay or failure relating to engaging or maintaining such service providers may affect the Fund’s ability to meet its investment objectives. Although the Fund and the Adviser seek to reduce these operational risks through controls and procedures, there is no way to completely protect against such risks.

Roundhill AVGO WeeklyPay™ ETF | SPECIAL TAX RISK  
Prospectus [Line Items]  
Risk [Text Block]

SPECIAL TAX RISK. The Fund intends to qualify annually and to elect to be treated as a regulated investment company under the Internal Revenue Code of 1986, as amended (the “Code”). To qualify for the favorable U.S. federal income tax treatment generally accorded to regulated investment companies, the Fund must, among other things, (i) derive in each taxable year at least 90% of its gross income from dividends, interest, payments with respect to securities loans and gains from the sale or other disposition of stock, securities or foreign currencies or other income derived with respect to its business of investing in such stock, securities or currencies, or net income derived from interests in certain publicly traded partnerships; (ii) diversify its holdings so that, at the end of each quarter of the taxable year, (a) at least 50% of the market value of the Fund’s assets is represented by cash and cash items (including receivables), U.S. government securities, the securities of other regulated investment companies and other securities, with such other securities of any one issuer generally limited for the purposes of this calculation to an amount not greater than 5% of the value of the Fund’s total assets and not greater than 10% of the outstanding voting securities of such issuer, and (b) not more than 25% of the value of its total assets is invested in the securities (other than U.S. government securities or the securities of other regulated investment companies) of any one issuer, or two or more issuers which the Fund controls which are engaged in the same, similar or related trades or businesses, or the securities of one or more of certain publicly traded partnerships; and (iii) distribute at least 90% of its investment company taxable income (which includes, among other items, dividends, interest and net short-term capital gains in excess of net long-term capital losses) and at least 90% of its net tax-exempt interest income each taxable year. There are certain exceptions for failure to qualify if the failure is for reasonable cause or is de minimis, and certain corrective action is taken and certain tax payments are made by the Fund.

 

The authority with regard to swaps entered into by regulated investment companies is unclear both as to the qualification under the income test and the identification of the issuer under the diversification test. The Fund intends to take the position that because the swaps held by the Fund reference securities that the income on the swaps are “other income” from the Fund’s business of investing in stocks and securities. In addition, the Fund intends to manage its investments in the swaps so that neither the exposure to issuer of the referenced security nor the exposure to any one counterparty of the swaps will exceed 25% of the gross value of the Fund’s portfolio at the end of any quarter.

 

If the Fund were to fail to meet the qualifying income test or asset diversification test and fail to qualify as a RIC, it would be taxed in the same manner as an ordinary corporation, and distributions to its shareholders would not be deductible by the Fund in computing its taxable income, which would adversely affect the Fund’s performance.

Roundhill AVGO WeeklyPay™ ETF | STRUCTURAL ETF RISKS  
Prospectus [Line Items]  
Risk [Text Block]

STRUCTURAL ETF RISKS. The Fund is an ETF. Accordingly, it is subject to certain risks associated with its unique structure.

 

Market Participants Risk. Only an Authorized Participant may engage in creation or redemption transactions directly with the Fund, and none of those Authorized Participants is obligated to engage in creation and/or redemption transactions. The Fund has a limited number of institutions that may act as Authorized Participants on an agency basis (i.e., on behalf of other market participants). To the extent that Authorized Participants exit the business or are unable to proceed with creation or redemption orders with respect to the Fund and no other Authorized Participant is able to step forward to create or redeem, Fund Shares may be more likely to trade at a premium or discount to NAV and possibly face trading halts or delisting. The Fund may also rely on a small number of third-party market makers to provide a market for the purchase and sale of Fund Shares but such market makers are under no obligation to do so. Decisions by Authorized Participants or market makers to reduce their role or step away from these activities in times of market stress could inhibit the effectiveness of the arbitrage process in maintaining the relationship between the underlying values of the Fund’s portfolio securities and the Fund’s market price. Any trading halt or other problem relating to the trading activity of these market makers or any issues disrupting the Authorized Participants’ ability to proceed with creation and/or redemption orders could result in a dramatic change in the spread between the Fund’s net asset value and the price at which Fund Shares are trading on the Exchange, which could result in a decrease in value of Fund Shares. This reduced effectiveness could result in Fund Shares trading at a premium or discount to net asset value and also in greater than normal intraday bid-ask spreads Fund Shares.

 

Cash Transactions Risk. The Fund currently expects to effect a significant portion of its creations and redemptions for cash, rather than in-kind securities. Paying redemption proceeds in cash rather than through in-kind delivery of portfolio securities may require the Fund to dispose of or sell portfolio securities or other assets at an inopportune time to obtain the cash needed to meet redemption orders. This may cause the Fund to sell a security and recognize a capital gain or loss that might not have been incurred if it had made a redemption in-kind. As a result, the Fund may pay out higher or lower annual capital gains distributions than ETFs that redeem in-kind. The use of cash creations and redemptions may also cause the Fund’s Shares to trade in the market at greater bid-ask spreads or greater premiums or discounts to the Fund’s NAV. Furthermore, the Fund may not be able to execute cash transactions for creation and redemption purposes at the same price used to determine the Fund’s NAV. To the extent that the maximum additional charge for creation or redemption transactions is insufficient to cover the execution shortfall, the Fund’s performance could be negatively impacted.

 

Costs of Buying and Selling Fund Shares. Due to the costs of buying or selling Fund Shares, including brokerage commissions imposed by brokers and bid/ask spreads, frequent trading of Fund Shares may significantly reduce investment results and an investment in Fund Shares may not be advisable for investors who anticipate regularly making small investments.

 

Premium/Discount Risk. As with all ETFs, Fund Shares may be bought and sold in the secondary market at market prices. The trading prices of Fund Shares in the secondary market may differ from the Fund’s daily net asset value per share and there may be times when the market price of the shares is more than the net asset value per share (premium) or less than the net asset value per share (discount). If a shareholder purchases Fund Shares at a time when the market price is at a premium to the net asset value or sells Fund Shares at a time when the market price is at a discount to the net asset value, the shareholder may pay more for, or receive less than, the underlying value of the Fund Shares, respectively. This risk is heightened in times of market volatility or periods of steep market declines.

 

Trading Risks. Although Fund Shares are listed for trading on the Exchange and may be traded on U.S. exchanges other than the Exchange, there can be no assurance that Fund Shares will trade with any volume, or at all, on any stock exchange. In stressed market conditions, the liquidity of Fund Shares may begin to mirror the liquidity of the Fund’s underlying portfolio holdings, which can be significantly less liquid than Fund Shares. Trading in Fund Shares on the Exchange may be halted due to market conditions or for reasons that, in the view of the Exchange, make trading in Fund Shares inadvisable. In addition, trading in Fund Shares on the Exchange is subject to trading halts caused by extraordinary market volatility pursuant to the Exchange’s “circuit breaker” rules. There can be no assurance that the requirements of the Exchange necessary to maintain the listing of the Fund will continue to be met or will remain unchanged.

Roundhill AVGO WeeklyPay™ ETF | U.S. GOVERNMENT SECURITIES RISK  
Prospectus [Line Items]  
Risk [Text Block]

U.S. GOVERNMENT SECURITIES RISK. U.S. government securities are subject to interest rate risk but generally do not involve the credit risks associated with investments in other types of debt securities. As a result, the yields available from U.S. government securities are generally lower than the yields available from other debt securities. U.S. government securities are guaranteed only as to the timely payment of interest and the payment of principal when held to maturity.

Roundhill AVGO WeeklyPay™ ETF | VALUATION RISK  
Prospectus [Line Items]  
Risk [Text Block]

VALUATION RISK. The Fund may hold securities or other assets that may be valued on the basis of factors other than market quotations. This may occur because the asset or security does not trade on a centralized exchange, or in times of market turmoil or reduced liquidity. There are multiple methods that can be used to value a portfolio holding when market quotations are not readily available. The value established for any portfolio holding at a point in time might differ from what would be produced using a different methodology or if it had been priced using market quotations. Portfolio holdings that are valued using techniques other than market quotations, including “fair valued” assets or securities, may be subject to greater fluctuation in their valuations from one day to the next than if market quotations were used. In addition, there is no assurance that the Fund could sell or close out a portfolio position for the value established for it at any time, and it is possible that the Fund would incur a loss because a portfolio position is sold or closed out at a discount to the valuation established by the Fund at that time. The Fund’s ability to value investments may be impacted by technological issues or errors by pricing services or other third-party service providers.

Roundhill AVGO WeeklyPay™ ETF | EQUITY SECURITIES RISK  
Prospectus [Line Items]  
Risk [Text Block]

EQUITY SECURITIES RISK. Equity securities are subject to changes in value, and their values may be more volatile than those of other asset classes. Equity securities prices fluctuate for several reasons, including changes in investors’ perceptions of the financial condition of an issuer or the general condition of the relevant equity market, such as market volatility, or when political or economic events affecting an issuer occur. Common stock prices may be particularly sensitive to rising interest rates, as the cost of capital rises and borrowing costs increase. Common stocks generally subject their holders to more risks than preferred stocks and debt securities because common stockholders’ claims are subordinated to those of holders of preferred stocks and debt securities upon the bankruptcy of the issuer.

Roundhill AVGO WeeklyPay™ ETF | SWAP AGREEMENTS RISK  
Prospectus [Line Items]  
Risk [Text Block]

SWAP AGREEMENTS RISK. The Fund will utilize swap agreements to derive its exposure to shares of AVGO. Swap agreements may involve greater risks than direct investment in securities as they may be leveraged and are subject to credit risk, counterparty risk and valuation risk. A swap agreement could result in losses if the underlying reference or asset does not perform as anticipated. In addition, many swaps trade over-the-counter and may be considered illiquid. It may not be possible for the Fund to liquidate a swap position at an advantageous time or price, which may result in significant losses.

Roundhill AVGO WeeklyPay™ ETF | REGULATED INVESTMENT COMPANY TAX RISKS  
Prospectus [Line Items]  
Risk [Text Block]

REGULATED INVESTMENT COMPANY TAX RISKS. The Fund intends to qualify annually and to elect to be treated as a regulated investment company under the Internal Revenue Code of 1986, as amended (the “Code”). To qualify for the favorable U.S. federal income tax treatment generally accorded to regulated investment companies, the Fund must, among other things, (i) derive in each taxable year at least 90% of its gross income from dividends, interest, payments with respect to securities loans and gains from the sale or other disposition of stock, securities or foreign currencies or other income derived with respect to its business of investing in such stock, securities or currencies, or net income derived from interests in certain publicly traded partnerships; (ii) diversify its holdings so that, at the end of each quarter of the taxable year, (a) at least 50% of the market value of the Fund’s assets is represented by cash and cash items (including receivables), U.S. government securities, the securities of other regulated investment companies and other securities, with such other securities of any one issuer generally limited for the purposes of this calculation to an amount not greater than 5% of the value of the Fund’s total assets and not greater than 10% of the outstanding voting securities of such issuer, and (b) not more than 25% of the value of its total assets is invested in the securities (other than U.S. government securities or the securities of other regulated investment companies) of any one issuer, or two or more issuers which the Fund controls which are engaged in the same, similar or related trades or businesses, or the securities of one or more of certain publicly traded partnerships; and (iii) distribute at least 90% of its investment company taxable income (which includes, among other items, dividends, interest and net short-term capital gains in excess of net long-term capital losses) and at least 90% of its net tax-exempt interest income each taxable year. There are certain exceptions for failure to qualify if the failure is for reasonable cause or is de minimis, and certain corrective action is taken and certain tax payments are made by the Fund.

 

If the Fund were to fail to meet the qualifying income test or asset diversification test and fail to qualify as a RIC, it would be taxed in the same manner as an ordinary corporation, and distributions to its shareholders would not be deductible by the Fund in computing its taxable income, which would adversely affect the Fund’s performance.

Roundhill AVGO WeeklyPay™ ETF | LARGE SHAREHOLDER RISK  
Prospectus [Line Items]  
Risk [Text Block]

LARGE SHAREHOLDER RISK. Certain shareholders, including affiliated funds advised by the Adviser, may from time to time own a significant portion of the Fund’s shares. In addition, a third-party investor, the Adviser or an affiliate of the Adviser (“Affiliate”), an authorized participant, a market maker, or another entity may invest in the Fund and hold its investment for a limited period solely to facilitate the commencement of the Fund or to help the Fund achieve a specified size or scale. There can be no assurance that any large shareholder will not redeem its investment, that the size of the Fund will be maintained at such levels, or that the Fund will continue to meet applicable listing requirements. Redemptions by large shareholders could have a significant negative impact on the Fund. In addition, transactions by large shareholders may account for a large percentage of the trading volume on the Fund’s listing exchange and may, therefore, have a material upward or downward effect on the market price of the shares.

 

To the extent that a significant percentage of the Fund’s shares are owned or controlled by a small number of account shareholders (or a single account shareholder), including funds or accounts over which the Adviser or an Affiliate has investment discretion, the Fund is subject to the risk that those shareholders may purchase or redeem Fund shares in significant amounts rapidly or unexpectedly, including as a result of an asset allocation decision made by the Adviser or an Affiliate. This may adversely affect the Fund’s performance if the Adviser is forced to sell portfolio securities or invest cash when it would not otherwise choose to do so. Redemptions of a large number of shares may affect the liquidity of the Fund’s portfolio, increase the Fund’s transaction costs, and accelerate the realization of taxable income and/or gains. In addition, a large redemption could result in the Fund’s current expenses being allocated over a smaller asset base, leading to an increase in the Fund’s gross expense ratio. Large purchases of the Fund’s shares may also adversely affect the Fund’s performance to the extent that the Fund is delayed in investing new cash or otherwise maintains a larger cash position than it ordinarily would, particularly if the Fund accepts cash for an order for the purchase of creation units of the Fund’s shares.

Roundhill AVGO WeeklyPay™ ETF | AVGO INVESTING RISKS  
Prospectus [Line Items]  
Risk [Text Block]

AVGO INVESTING RISKS. The Fund will have significant exposure to AVGO through its investments in swap agreements that utilize AVGO as the reference asset. Accordingly, the Fund will subject to the risks of AVGO, set forth below.

 

AVGO ISSUER-SPECIFIC RISKS. Issuer-specific attributes may cause an investment held by the Fund to be more volatile than the market generally. The value of an individual security or particular type of security may be more volatile than the market as a whole and may perform differently from the value of the market as a whole. AVGO operates in the highly competitive semiconductor industry, where rapid technological innovation and shifting market dynamics can significantly impact its business. AVGO relies on a concentrated customer base and an extensive supply chain to manufacture and distribute its products. A significant portion of AVGO’s revenue comes from a few major customers, including large smartphone manufacturers, cloud service providers and networking companies. The loss of a key customer or reduced orders could materially impact revenue. AVGO depends on a complex global supply chain for semiconductor fabrication, components, and raw materials. Disruptions due to geopolitical tensions, natural disasters or trade restrictions could impact production and delivery schedules. AVGO outsources a substantial portion of its semiconductor manufacturing to third-party foundries. Any capacity constraints, pricing changes, or disruptions at these foundries could negatively affect AVGO’s ability to meet demand. AVGO operates in a highly regulated industry and is exposed to geopolitical risks that could affect its business. AVGO’s ability to sell semiconductor products internationally, particularly in China, is subject to trade policies, export controls, and government-imposed restrictions. U.S. sanctions or export limitations on chip technology could reduce AVGO’s market access and revenue. Given AVGO’s presence in global markets, trade tensions between the U.S. and China could impact its business operations, supply chain, and customer relationships. Any escalation of trade conflicts, tariffs, or restrictions on semiconductor exports could materially affect financial performance. AVGO has faced antitrust investigations and regulatory scrutiny regarding its business practices. Changes in antitrust laws, new regulatory enforcement, or limitations on acquisitions could impact its business strategy. AVGO has taken on significant debt to finance acquisitions. Increased leverage could lead to higher interest expenses, reduced financial flexibility, and potential credit rating downgrades. AVGO earns a significant portion of its revenue from international markets, including Asia, Europe, and Latin America, where sales may be denominated in currencies such as the euro, Japanese yen, British pound and Chinese yuan. However, a large share of Broadcom’s manufacturing, operating expenses, and supply chain costs are denominated in other currencies, creating an exposure to currency fluctuations that could affect profit margins. Foreign-denominated revenue and assets must be translated into U.S. dollar for financial reporting purposes. If the U.S. dollar strengthens relative to other currencies, AVGO’s reported earnings and revenue from international markets may decline, even if local currency sales remain stable. Additionally, AVGO faces transaction risks when converting foreign currency earnings into U.S. dollars, as unfavorable exchange rate movements could reduce profitability.

 

ASIAN GEOPOLITICAL TENSIONS RISK. AVGO has significant exposure to Asia as a result of its operations, supply chain and location of its customers. Asian geopolitical developments, such as trade disputes, territorial conflicts, regulatory changes, sanctions, military actions, or changes in diplomatic relations, could materially impact AVGO’s business operations, financial performance and stock price. Tensions between major economies in the region, including but not limited to China, Taiwan, South Korea, Japan and India, as well as broader U.S.-Asia relations, may lead to increased market volatility, disruptions in trade, supply chain constraints, or restrictions on capital flows. Governments in these regions may impose tariffs, export controls, or other regulatory measures that could negatively affect certain industries, including technology, manufacturing, and consumer goods. Additionally, political instability, social unrest, or unexpected policy shifts could create further uncertainty for businesses operating in the region.

 

INDIRECT INVESTMENT RISK. Broadcom Inc. is not affiliated with the Trust, the Fund, the Adviser, the Sub-Adviser or any affiliates thereof and is not involved with this offering in any way, and has no obligation to consider the Fund in taking any corporate actions that might affect the value of the Fund. The Trust, the Fund, the Adviser, the Sub-Adviser or any affiliate are not responsible for the performance of AVGO and make no representation as to the performance of AVGO. Investing in the Fund is not equivalent to investing in AVGO. Fund shareholders will not have voting rights or rights to receive dividends or other distributions or any other rights with respect to AVGO.

 

INFORMATION TECHNOLOGY COMPANIES RISK. Information technology companies face intense competition, both domestically and internationally, which may have an adverse effect on profit margins. Like other technology companies, information technology companies may have limited product lines, markets, financial resources or personnel. The products of information technology companies may face obsolescence due to rapid technological developments, frequent new product introduction, unpredictable changes in growth rates and competition for the services of qualified personnel. Companies in the information technology sector are heavily dependent on patent and intellectual property rights. The loss or impairment of these rights may adversely affect the profitability of these companies. Information technology companies are facing increased government and regulatory scrutiny and may be subject to adverse government or regulatory action.

 

LARGE CAPITALIZATION COMPANIES RISK. Large capitalization companies may be less able than smaller capitalization companies to adapt to changing market conditions. Large capitalization companies may be more mature and subject to more limited growth potential compared with smaller capitalization companies. During different market cycles, the performance of large capitalization companies has trailed the overall performance of the broader securities markets.

 

SEMICONDUCTOR COMPANIES RISK. Semiconductor companies face intense competition, both domestically and internationally, and such competition may have an adverse effect on profit margins. Semiconductor companies may have limited product lines, markets, financial resources or personnel. Semiconductor companies’ supply chain and operations are dependent on the availability of materials that meet exacting standards and the use of third parties to provide components and services. Semiconductor companies may rely on a limited number of suppliers, or upon suppliers in a single location, for certain materials, equipment or tools. Finding and qualifying alternate or additional suppliers can be a lengthy process that can cause production delays or impose unforeseen costs, and such alternatives may not be available at all. Production can be disrupted by the unavailability of resources, such as water, silicon, electricity, gases and other materials. Suppliers may also increase prices or encounter cybersecurity or other issues that can disrupt production or increase production costs. The products of semiconductor companies may face obsolescence due to rapid technological developments and frequent new product introduction, unpredictable changes in growth rates and competition for the services of qualified personnel. Capital equipment expenditures could be substantial, and equipment generally suffers from rapid obsolescence. Companies in the semiconductor industry are heavily dependent on patent and intellectual property rights. The loss or impairment of these rights, would adversely affect the profitability of these companies.

 

UNITED STATES RISK. Certain changes in the U.S. economy, such as when the U.S. economy weakens or when its financial markets decline, may have an adverse effect on the securities to which the Fund has exposure.

NON-DIVERSIFICATION RISK. As a “non-diversified” fund, the Fund may hold a smaller number of portfolio securities than many other funds. To the extent the Fund invests in a relatively small number of issuers, a decline in the market value of a particular security held by the Fund may affect its value more than if it invested in a larger number of issuers. The value of the Fund Shares may be more volatile than the values of shares of more diversified funds.

Roundhill BABA WeeklyPay™ ETF | MARKET RISK  
Prospectus [Line Items]  
Risk [Text Block]

MARKET RISK. Market risk is the risk that a particular investment, or Fund Shares in general, may fall in value. Securities are subject to market fluctuations caused by real or perceived adverse economic, political, and regulatory factors or market developments, changes in interest rates, disruptions to trade, impositions of tariffs and perceived trends in securities prices. Fund Shares could decline in value or underperform other investments. In addition, local, regional or global events such as war, acts of terrorism, market manipulation, government defaults, government shutdowns, regulatory actions, political changes, diplomatic developments, the imposition of sanctions and other similar measures, spread of infectious diseases or other public health issues, recessions, natural disasters, or other events could have a significant negative impact on the Fund and its investments. Any of such circumstances could have a materially negative impact on the value of Fund Shares, the liquidity of an investment, and may result in increased market volatility. During any such events, Fund Shares may trade at increased premiums or discounts to their net asset value, the bid/ask spread on Fund Shares may widen and the returns on investment may fluctuate.

Roundhill BABA WeeklyPay™ ETF | LIQUIDITY RISK  
Prospectus [Line Items]  
Risk [Text Block]

LIQUIDITY RISK. The market for swap agreements that reference BABA shares may be subject to periods of illiquidity. During such times it may be difficult or impossible to buy or sell a position at the desired price. Market disruptions or volatility can also make it difficult to find a counterparty willing to transact at a reasonable price and sufficient size. Illiquid markets may cause losses, which could be significant. The large size of the positions which the Fund may acquire increases the risk of illiquidity, may make its positions more difficult to liquidate, and may increase the losses incurred while trying to do so. Such large positions also may impact the price of swap agreements on BABA shares.

Roundhill BABA WeeklyPay™ ETF | ACTIVE MANAGEMENT RISK  
Prospectus [Line Items]  
Risk [Text Block]

ACTIVE MANAGEMENT RISK. The Fund is actively-managed and its performance reflects investment decisions that the Adviser and/or Sub-Adviser makes for the Fund. Such judgments about the Fund’s investments may prove to be incorrect. If the investments selected and the strategies employed by the Fund fail to produce the intended results, the Fund could underperform as compared to other funds with similar investment objectives and/or strategies, or could have negative returns.

Roundhill BABA WeeklyPay™ ETF | ACTIVE MARKET RISK  
Prospectus [Line Items]  
Risk [Text Block]

ACTIVE MARKET RISK. Although Fund Shares are listed for trading on the Exchange, there can be no assurance that an active trading market for Fund Shares will develop or be maintained. Fund Shares trade on the Exchange at market prices that may be below, at or above the Fund’s net asset value. Securities, including Fund Shares, are subject to market fluctuations and liquidity constraints that may be caused by such factors as economic, political, or regulatory developments, changes in interest rates, and/or perceived trends in securities prices. Fund Shares could decline in value or underperform other investments.

Roundhill BABA WeeklyPay™ ETF | ASSET CLASS RISK

Risk [Text Block]

CONCENTRATION RISK. The Fund is susceptible to an increased risk of loss, including losses due to adverse events that affect the Fund’s investments more than the market as a whole, to the extent that the Fund’s investments are concentrated in investments that provide exposure to BABA and the industry to which it is assigned.

Roundhill BABA WeeklyPay™ ETF | COUNTERPARTY RISK  
Prospectus [Line Items]  
Risk [Text Block]

COUNTERPARTY RISK. Fund transactions involving a counterparty are subject to the risk that the counterparty will not fulfill its obligation to the Fund. Counterparty risk may arise because of the counterparty’s financial condition (i.e., financial difficulties, bankruptcy, or insolvency), market activities and developments, or other reasons, whether foreseen or not. A counterparty’s inability to fulfill its obligation may result in significant financial loss to the Fund. The Fund may be unable to recover its investment from the counterparty or may obtain a limited recovery, and/or recovery may be delayed.

CREDIT RISK. An issuer or other obligated party of a debt security may be unable or unwilling to make dividend, interest and/or principal payments when due. In addition, the value of a debt security may decline because of concerns about the issuer’s ability or unwillingness to make such payments.

Roundhill BABA WeeklyPay™ ETF | CURRENT MARKET CONDITIONS RISK  
Prospectus [Line Items]  
Risk [Text Block]

CURRENT MARKET CONDITIONS RISK. Current market conditions risk is the risk that a particular investment, or Fund Shares in general, may fall in value due to current market conditions. As a means to fight inflation, which remains at elevated levels, the Federal Reserve and certain foreign central banks have raised interest rates; however, the Federal Reserve has recently lowered interest rates and may continue to do so. U.S. regulators have proposed several changes to market and issuer regulations which would directly impact the Fund, and any regulatory changes could adversely impact the Fund’s ability to achieve its investment strategies or make certain investments. Recent and potential future bank failures could result in disruption to the broader banking industry or markets generally and reduce confidence in financial institutions and the economy as a whole, which may also heighten market volatility and reduce liquidity. Additionally, challenges in commercial real estate markets, including rising interest rates, declining valuations and increasing vacancies, could have a broader impact on financial markets. The ongoing adversarial political climate in the United States, as well as political and diplomatic events both domestic and abroad, have and may continue to have an adverse impact the U.S. regulatory landscape, markets and investor behavior, which could have a negative impact on the Fund’s investments and operations. The change in administration resulting from the 2024 United States national elections could result in significant impacts to international trade relations, tax and immigration policies, and other aspects of the national and international political and financial landscape, which could affect, among other things, inflation and the securities markets generally. Other unexpected political, regulatory and diplomatic events within the U.S. and abroad may affect investor and consumer confidence and may adversely impact financial markets and the broader economy. For example, ongoing armed conflicts between Russia and Ukraine in Europe and among Israel, Iran, Hamas and other militant groups in the Middle East, have caused and could continue to cause significant market disruptions and volatility within the markets in Russia, Europe, the Middle East and the United States. The hostilities and sanctions resulting from those hostilities have and could continue to have a significant impact on certain Fund investments as well as Fund performance and liquidity. The economies of the United States and its trading partners, as well as the financial markets generally, may be adversely impacted by trade disputes, including the imposition of tariffs, and other matters. For example, the United States has imposed trade barriers and restrictions on China. In addition, the Chinese government is engaged in a longstanding dispute with Taiwan, continually threatening an invasion. If the political climate between the United States and China does not improve or continues to deteriorate, if China were to attempt invading Taiwan, or if other geopolitical conflicts develop or worsen, economies, markets and individual securities may be adversely affected, and the value of the Fund’s assets may go down. A public health crisis and the ensuing policies enacted by governments and central banks may cause significant volatility and uncertainty in global financial markets, negatively impacting global growth prospects. As the COVID-19 global pandemic illustrated, such events may affect certain geographic regions, countries, sectors and industries more significantly than others. Advancements in technology may also adversely impact markets and the overall performance of the Fund. For instance, the economy may be significantly impacted by the advanced development and increased regulation of artificial intelligence. Additionally, cyber security breaches of both government and non-government entities could have negative impacts on infrastructure and the ability of such entities, including the Fund, to operate properly. These events, and any other future events, may adversely affect the prices and liquidity of the Fund’s portfolio investments and could result in disruptions in the trading markets.

Roundhill BABA WeeklyPay™ ETF | CYBERSECURITY RISK  
Prospectus [Line Items]  
Risk [Text Block]

CYBERSECURITY RISK. Failures or breaches of the electronic systems of the Fund, the Fund’s adviser, sub-adviser, distributor and other service providers, market makers, Authorized Participants or the issuers of securities in which the Fund invests have the ability to cause disruptions, negatively impact the Fund’s business operations and/or potentially result in financial losses to the Fund and its shareholders. While the Fund has established business continuity plans and risk management systems seeking to address system breaches or failures, there are inherent limitations in such plans and systems. Furthermore, the Fund cannot control the cybersecurity plans and systems of the Fund’s other service providers, market makers, Authorized Participants or issuers of securities in which the Fund invests.

Roundhill BABA WeeklyPay™ ETF | DEBT SECURITIES RISK  
Prospectus [Line Items]  
Risk [Text Block]

DEBT SECURITIES RISK. Investments in debt securities subject the holder to the credit risk of the issuer. Credit risk refers to the possibility that the issuer or other obligor of a security will not be able or willing to make payments of interest and principal when due. Generally, the value of debt securities will change inversely with changes in interest rates. To the extent that interest rates rise, certain underlying obligations may be paid off substantially slower than originally anticipated and the value of those securities may fall sharply. During periods of falling interest rates, the income received by the Fund may decline. If the principal on a debt security is prepaid before expected, the prepayments of principal may have to be reinvested in obligations paying interest at lower rates. Debt securities generally do not trade on a securities exchange making them generally less liquid and more difficult to value than common stock.

Roundhill BABA WeeklyPay™ ETF | DERIVATIVES RISK  
Prospectus [Line Items]  
Risk [Text Block]

DERIVATIVES RISK. The use of derivative instruments involves risks different from, or possibly greater than, the risks associated with investing directly in securities and other traditional investments. These risks include: (i) the risk that the counterparty to a derivative transaction may not fulfill its contractual obligations; (ii) risk of mispricing or improper valuation; and (iii) the risk that changes in the value of the derivative may not correlate perfectly with the underlying asset. Derivative prices are highly volatile and may fluctuate substantially during a short period of time. Such prices are influenced by numerous factors that affect the markets, including, but not limited to: changing supply and demand relationships; government programs and policies; national and international political and economic events, changes in interest rates, inflation and deflation and changes in supply and demand relationships. Trading derivative instruments involves risks different from, or possibly greater than, the risks associated with investing directly in securities. Derivative contracts ordinarily have leverage inherent in their terms. The use of leverage may cause the Fund to liquidate portfolio positions when it would not be advantageous to do so in order to satisfy its obligations or to meet regulatory or contractual requirements for derivatives. The use of derivatives can magnify potential for gain or loss and, therefore, amplify the effects of market volatility on share price.

Roundhill BABA WeeklyPay™ ETF | DISTRIBUTION TAX RISK  
Prospectus [Line Items]  
Risk [Text Block]

DISTRIBUTION TAX RISK. The Fund currently expects to make distributions on a weekly basis. Such frequent distributions may expose investors to increased tax liabilities. However, these distributions may exceed the Fund’s income and gains for the Fund’s taxable year. Distributions in excess of the Fund’s current and accumulated earnings and profits will be treated as a return of capital. A return of capital distribution generally will not be taxable but will reduce the shareholder’s cost basis and will result in a higher capital gain or lower capital loss when those Fund Shares on which the distribution was received are sold. Once a Fund shareholder’s cost basis is reduced to zero, further distributions will be treated as capital gain if the Fund shareholder holds Fund Shares as capital assets. Additionally, any capital returned through distributions will be distributed after payment of Fund fees and expenses. Because a portion of the Fund’s distributions may consist of return of capital, the Fund may not be an appropriate investment for investors who do not want their principal investment in the Fund to decrease over time or who do not wish to receive return of capital in a given period. In the event that a shareholder purchases Fund Shares shortly before a distribution by the Fund, the entire distribution may be taxable to the shareholder even though a portion of the distribution effectively represents a return of the purchase price.

Roundhill BABA WeeklyPay™ ETF | ETF RISK  
Prospectus [Line Items]  
Risk [Text Block]

ETF RISK. The Fund may invest in ETFs. The value of an ETF held by the Fund will fluctuate over time based on fluctuations in the values of the assets held by the ETF, which may be affected by changes in general economic conditions, expectations for future growth and profits, interest rates and the supply and demand for those assets. When the Fund invests in an ETF, it will bear a proportionate share of the ETF’s expenses. Brokerage, tax and other expenses may negatively impact the performance of the ETF and, in turn, the value of the Fund Shares. An ETF that tracks an index may not exactly match the performance of the index due to cash drag, differences between the portfolio of the ETF and the components of the index, expenses and other factors.

Roundhill BABA WeeklyPay™ ETF | INFLATION RISK  
Prospectus [Line Items]  
Risk [Text Block]

INFLATION RISK. Inflation risk is the risk that the value of assets or income from investments will be less in the future as inflation decreases the value of money. As inflation increases, the present value of the Fund’s assets and distributions may decline. This risk is more prevalent with respect to fixed income securities held by the Fund.

Roundhill BABA WeeklyPay™ ETF | Interest Rate Risk [Member]  
Prospectus [Line Items]  
Risk [Text Block]

INTEREST RATE RISK. Interest rate risk is the risk that the value of the debt securities in the Fund’s portfolio will decline because of rising market interest rates. Interest rate risk is generally lower for shorter term debt securities and higher for longer-term debt securities. Duration is a reasonably accurate measure of a debt security’s price sensitivity to changes in interest rates and a common measure of interest rate risk. Duration measures a debt security’s expected life on a present value basis, taking into account the debt security’s yield, interest payments and final maturity. In general, duration represents the expected percentage change in the value of a security for an immediate 1% change in interest rates. For example, the price of a debt security with a three-year duration would be expected to drop by approximately 3% in response to a 1% increase in interest rates. Therefore, prices of debt securities with shorter durations tend to be less sensitive to interest rate changes than debt securities with longer durations. As the value of a debt security changes over time, so will its duration.

Roundhill BABA WeeklyPay™ ETF | LEGISLATION AND LITIGATION RISK  
Prospectus [Line Items]  
Risk [Text Block]

LEGISLATION AND LITIGATION RISK. Legislation or litigation that affects the value of assets or securities held by the Fund may reduce the value of the Fund. From time to time, various legislative initiatives are proposed that may have a negative impact on certain assets or securities in which the Fund invests. In addition, litigation regarding any of the assets or securities owned by the Fund may negatively impact the value of the Shares. Such legislation or litigation may cause the Fund to lose value or may result in higher portfolio turnover if the Adviser determines to sell such a holding.

Roundhill BABA WeeklyPay™ ETF | LEVERAGE RISK  
Prospectus [Line Items]  
Risk [Text Block]

LEVERAGE RISK. The Fund obtains investment exposure in excess of its net assets by utilizing leverage and may lose more money in market conditions that are adverse to its investment objectives than a fund that does not utilize leverage. An investment in the Fund is exposed to the risk that a decline in the weekly performance of shares of BABA will be magnified. This means that an investment in the Fund will be reduced by an amount equal to 1.2% for every 1% weekly decline in the market value of the BABA shares, not including the costs of financing leverage and other operating expenses, which would further reduce its value. The Fund could theoretically lose an amount greater than its net assets in the event the market value of BABA shares decline more than 83.33% over a calendar week. Leverage will also have the effect of magnifying any differences in the Fund’s correlation with BABA shares.

Roundhill BABA WeeklyPay™ ETF | MONEY MARKET INSTRUMENTS RISK  
Prospectus [Line Items]  
Risk [Text Block]

MONEY MARKET INSTRUMENTS RISK. The value of money market instruments may be affected by changing interest rates and by changes in the credit ratings of the investments. If a significant amount of the Fund’s assets are invested in money market instruments, it will be more difficult for the Fund to achieve its investment objectives. An investment in a money market fund is not insured or guaranteed by the FDIC or any other government agency. It is possible to lose money by investing in a money market fund.

Roundhill BABA WeeklyPay™ ETF | OPERATIONAL RISK  
Prospectus [Line Items]  
Risk [Text Block]

OPERATIONAL RISK. The Fund is subject to risks arising from various operational factors, including, but not limited to, human error, processing and communication errors, errors of the Fund’s service providers, counterparties or other third-parties, failed or inadequate processes and technology or systems failures. The Fund relies on third-parties for a range of services, including custody. Any delay or failure relating to engaging or maintaining such service providers may affect the Fund’s ability to meet its investment objectives. Although the Fund and the Adviser seek to reduce these operational risks through controls and procedures, there is no way to completely protect against such risks.

Roundhill BABA WeeklyPay™ ETF | SPECIAL TAX RISK  
Prospectus [Line Items]  
Risk [Text Block]

SPECIAL TAX RISK. The Fund intends to qualify annually and to elect to be treated as a regulated investment company under the Internal Revenue Code of 1986, as amended (the “Code”). To qualify for the favorable U.S. federal income tax treatment generally accorded to regulated investment companies, the Fund must, among other things, (i) derive in each taxable year at least 90% of its gross income from dividends, interest, payments with respect to securities loans and gains from the sale or other disposition of stock, securities or foreign currencies or other income derived with respect to its business of investing in such stock, securities or currencies, or net income derived from interests in certain publicly traded partnerships; (ii) diversify its holdings so that, at the end of each quarter of the taxable year, (a) at least 50% of the market value of the Fund’s assets is represented by cash and cash items (including receivables), U.S. government securities, the securities of other regulated investment companies and other securities, with such other securities of any one issuer generally limited for the purposes of this calculation to an amount not greater than 5% of the value of the Fund’s total assets and not greater than 10% of the outstanding voting securities of such issuer, and (b) not more than 25% of the value of its total assets is invested in the securities (other than U.S. government securities or the securities of other regulated investment companies) of any one issuer, or two or more issuers which the Fund controls which are engaged in the same, similar or related trades or businesses, or the securities of one or more of certain publicly traded partnerships; and (iii) distribute at least 90% of its investment company taxable income (which includes, among other items, dividends, interest and net short-term capital gains in excess of net long-term capital losses) and at least 90% of its net tax-exempt interest income each taxable year. There are certain exceptions for failure to qualify if the failure is for reasonable cause or is de minimis, and certain corrective action is taken and certain tax payments are made by the Fund.

 

The authority with regard to swaps entered into by regulated investment companies is unclear both as to the qualification under the income test and the identification of the issuer under the diversification test. The Fund intends to take the position that because the swaps held by the Fund reference securities that the income on the swaps are “other income” from the Fund’s business of investing in stocks and securities. In addition, the Fund intends to manage its investments in the swaps so that neither the exposure to issuer of the referenced security nor the exposure to any one counterparty of the swaps will exceed 25% of the gross value of the Fund’s portfolio at the end of any quarter.

 

If the Fund were to fail to meet the qualifying income test or asset diversification test and fail to qualify as a RIC, it would be taxed in the same manner as an ordinary corporation, and distributions to its shareholders would not be deductible by the Fund in computing its taxable income, which would adversely affect the Fund’s performance.

Roundhill BABA WeeklyPay™ ETF | STRUCTURAL ETF RISKS  
Prospectus [Line Items]  
Risk [Text Block]

STRUCTURAL ETF RISKS. The Fund is an ETF. Accordingly, it is subject to certain risks associated with its unique structure.

 

Market Participants Risk. Only an Authorized Participant may engage in creation or redemption transactions directly with the Fund, and none of those Authorized Participants is obligated to engage in creation and/or redemption transactions. The Fund has a limited number of institutions that may act as Authorized Participants on an agency basis (i.e., on behalf of other market participants). To the extent that Authorized Participants exit the business or are unable to proceed with creation or redemption orders with respect to the Fund and no other Authorized Participant is able to step forward to create or redeem, Fund Shares may be more likely to trade at a premium or discount to NAV and possibly face trading halts or delisting. The Fund may also rely on a small number of third-party market makers to provide a market for the purchase and sale of Fund Shares but such market makers are under no obligation to do so. Decisions by Authorized Participants or market makers to reduce their role or step away from these activities in times of market stress could inhibit the effectiveness of the arbitrage process in maintaining the relationship between the underlying values of the Fund’s portfolio securities and the Fund’s market price. Any trading halt or other problem relating to the trading activity of these market makers or any issues disrupting the Authorized Participants’ ability to proceed with creation and/or redemption orders could result in a dramatic change in the spread between the Fund’s net asset value and the price at which Fund Shares are trading on the Exchange, which could result in a decrease in value of Fund Shares. This reduced effectiveness could result in Fund Shares trading at a premium or discount to net asset value and also in greater than normal intraday bid-ask spreads Fund Shares.

 

Cash Transactions Risk. The Fund currently expects to effect a significant portion of its creations and redemptions for cash, rather than in-kind securities. Paying redemption proceeds in cash rather than through in-kind delivery of portfolio securities may require the Fund to dispose of or sell portfolio securities or other assets at an inopportune time to obtain the cash needed to meet redemption orders. This may cause the Fund to sell a security and recognize a capital gain or loss that might not have been incurred if it had made a redemption in-kind. As a result, the Fund may pay out higher or lower annual capital gains distributions than ETFs that redeem in-kind. The use of cash creations and redemptions may also cause the Fund’s Shares to trade in the market at greater bid-ask spreads or greater premiums or discounts to the Fund’s NAV. Furthermore, the Fund may not be able to execute cash transactions for creation and redemption purposes at the same price used to determine the Fund’s NAV. To the extent that the maximum additional charge for creation or redemption transactions is insufficient to cover the execution shortfall, the Fund’s performance could be negatively impacted.

 

Costs of Buying and Selling Fund Shares. Due to the costs of buying or selling Fund Shares, including brokerage commissions imposed by brokers and bid/ask spreads, frequent trading of Fund Shares may significantly reduce investment results and an investment in Fund Shares may not be advisable for investors who anticipate regularly making small investments.

 

Premium/Discount Risk. As with all ETFs, Fund Shares may be bought and sold in the secondary market at market prices. The trading prices of Fund Shares in the secondary market may differ from the Fund’s daily net asset value per share and there may be times when the market price of the shares is more than the net asset value per share (premium) or less than the net asset value per share (discount). If a shareholder purchases Fund Shares at a time when the market price is at a premium to the net asset value or sells Fund Shares at a time when the market price is at a discount to the net asset value, the shareholder may pay more for, or receive less than, the underlying value of the Fund Shares, respectively. This risk is heightened in times of market volatility or periods of steep market declines.

 

Trading Risks. Although Fund Shares are listed for trading on the Exchange and may be traded on U.S. exchanges other than the Exchange, there can be no assurance that Fund Shares will trade with any volume, or at all, on any stock exchange. In stressed market conditions, the liquidity of Fund Shares may begin to mirror the liquidity of the Fund’s underlying portfolio holdings, which can be significantly less liquid than Fund Shares. Trading in Fund Shares on the Exchange may be halted due to market conditions or for reasons that, in the view of the Exchange, make trading in Fund Shares inadvisable. In addition, trading in Fund Shares on the Exchange is subject to trading halts caused by extraordinary market volatility pursuant to the Exchange’s “circuit breaker” rules. There can be no assurance that the requirements of the Exchange necessary to maintain the listing of the Fund will continue to be met or will remain unchanged.

Roundhill BABA WeeklyPay™ ETF | U.S. GOVERNMENT SECURITIES RISK  
Prospectus [Line Items]  
Risk [Text Block]

U.S. GOVERNMENT SECURITIES RISK. U.S. government securities are subject to interest rate risk but generally do not involve the credit risks associated with investments in other types of debt securities. As a result, the yields available from U.S. government securities are generally lower than the yields available from other debt securities. U.S. government securities are guaranteed only as to the timely payment of interest and the payment of principal when held to maturity.

Roundhill BABA WeeklyPay™ ETF | VALUATION RISK  
Prospectus [Line Items]  
Risk [Text Block]

VALUATION RISK. The Fund may hold securities or other assets that may be valued on the basis of factors other than market quotations. This may occur because the asset or security does not trade on a centralized exchange, or in times of market turmoil or reduced liquidity. There are multiple methods that can be used to value a portfolio holding when market quotations are not readily available. The value established for any portfolio holding at a point in time might differ from what would be produced using a different methodology or if it had been priced using market quotations. Portfolio holdings that are valued using techniques other than market quotations, including “fair valued” assets or securities, may be subject to greater fluctuation in their valuations from one day to the next than if market quotations were used. In addition, there is no assurance that the Fund could sell or close out a portfolio position for the value established for it at any time, and it is possible that the Fund would incur a loss because a portfolio position is sold or closed out at a discount to the valuation established by the Fund at that time. The Fund’s ability to value investments may be impacted by technological issues or errors by pricing services or other third-party service providers.

Roundhill BABA WeeklyPay™ ETF | EQUITY SECURITIES RISK  
Prospectus [Line Items]  
Risk [Text Block]

EQUITY SECURITIES RISK. Equity securities are subject to changes in value, and their values may be more volatile than those of other asset classes. Equity securities prices fluctuate for several reasons, including changes in investors’ perceptions of the financial condition of an issuer or the general condition of the relevant equity market, such as market volatility, or when political or economic events affecting an issuer occur. Common stock prices may be particularly sensitive to rising interest rates, as the cost of capital rises and borrowing costs increase. Common stocks generally subject their holders to more risks than preferred stocks and debt securities because common stockholders’ claims are subordinated to those of holders of preferred stocks and debt securities upon the bankruptcy of the issuer.

Roundhill BABA WeeklyPay™ ETF | SWAP AGREEMENTS RISK  
Prospectus [Line Items]  
Risk [Text Block]

SWAP AGREEMENTS RISK. The Fund will utilize swap agreements to derive its exposure to shares of BABA. Swap agreements may involve greater risks than direct investment in securities as they may be leveraged and are subject to credit risk, counterparty risk and valuation risk. A swap agreement could result in losses if the underlying reference or asset does not perform as anticipated. In addition, many swaps trade over-the-counter and may be considered illiquid. It may not be possible for the Fund to liquidate a swap position at an advantageous time or price, which may result in significant losses.

Roundhill BABA WeeklyPay™ ETF | REGULATED INVESTMENT COMPANY TAX RISKS  
Prospectus [Line Items]  
Risk [Text Block]

REGULATED INVESTMENT COMPANY TAX RISKS. The Fund intends to qualify annually and to elect to be treated as a regulated investment company under the Internal Revenue Code of 1986, as amended (the “Code”). To qualify for the favorable U.S. federal income tax treatment generally accorded to regulated investment companies, the Fund must, among other things, (i) derive in each taxable year at least 90% of its gross income from dividends, interest, payments with respect to securities loans and gains from the sale or other disposition of stock, securities or foreign currencies or other income derived with respect to its business of investing in such stock, securities or currencies, or net income derived from interests in certain publicly traded partnerships; (ii) diversify its holdings so that, at the end of each quarter of the taxable year, (a) at least 50% of the market value of the Fund’s assets is represented by cash and cash items (including receivables), U.S. government securities, the securities of other regulated investment companies and other securities, with such other securities of any one issuer generally limited for the purposes of this calculation to an amount not greater than 5% of the value of the Fund’s total assets and not greater than 10% of the outstanding voting securities of such issuer, and (b) not more than 25% of the value of its total assets is invested in the securities (other than U.S. government securities or the securities of other regulated investment companies) of any one issuer, or two or more issuers which the Fund controls which are engaged in the same, similar or related trades or businesses, or the securities of one or more of certain publicly traded partnerships; and (iii) distribute at least 90% of its investment company taxable income (which includes, among other items, dividends, interest and net short-term capital gains in excess of net long-term capital losses) and at least 90% of its net tax-exempt interest income each taxable year. There are certain exceptions for failure to qualify if the failure is for reasonable cause or is de minimis, and certain corrective action is taken and certain tax payments are made by the Fund.

 

If the Fund were to fail to meet the qualifying income test or asset diversification test and fail to qualify as a RIC, it would be taxed in the same manner as an ordinary corporation, and distributions to its shareholders would not be deductible by the Fund in computing its taxable income, which would adversely affect the Fund’s performance.

Roundhill BABA WeeklyPay™ ETF | LARGE SHAREHOLDER RISK  
Prospectus [Line Items]  
Risk [Text Block]

LARGE SHAREHOLDER RISK. Certain shareholders, including affiliated funds advised by the Adviser, may from time to time own a significant portion of the Fund’s shares. In addition, a third-party investor, the Adviser or an affiliate of the Adviser (“Affiliate”), an authorized participant, a market maker, or another entity may invest in the Fund and hold its investment for a limited period solely to facilitate the commencement of the Fund or to help the Fund achieve a specified size or scale. There can be no assurance that any large shareholder will not redeem its investment, that the size of the Fund will be maintained at such levels, or that the Fund will continue to meet applicable listing requirements. Redemptions by large shareholders could have a significant negative impact on the Fund. In addition, transactions by large shareholders may account for a large percentage of the trading volume on the Fund’s listing exchange and may, therefore, have a material upward or downward effect on the market price of the shares.

 

To the extent that a significant percentage of the Fund’s shares are owned or controlled by a small number of account shareholders (or a single account shareholder), including funds or accounts over which the Adviser or an Affiliate has investment discretion, the Fund is subject to the risk that those shareholders may purchase or redeem Fund shares in significant amounts rapidly or unexpectedly, including as a result of an asset allocation decision made by the Adviser or an Affiliate. This may adversely affect the Fund’s performance if the Adviser is forced to sell portfolio securities or invest cash when it would not otherwise choose to do so. Redemptions of a large number of shares may affect the liquidity of the Fund’s portfolio, increase the Fund’s transaction costs, and accelerate the realization of taxable income and/or gains. In addition, a large redemption could result in the Fund’s current expenses being allocated over a smaller asset base, leading to an increase in the Fund’s gross expense ratio. Large purchases of the Fund’s shares may also adversely affect the Fund’s performance to the extent that the Fund is delayed in investing new cash or otherwise maintains a larger cash position than it ordinarily would, particularly if the Fund accepts cash for an order for the purchase of creation units of the Fund’s shares.

Roundhill BABA WeeklyPay™ ETF | BABA INVESTING RISKS  
Prospectus [Line Items]  
Risk [Text Block]

BABA INVESTING RISKS. The Fund will have significant exposure to BABA through its investments in swap agreements that utilize BABA as the reference asset. Accordingly, the Fund will subject to the risks of BABA, set forth below.

 

BABA ISSUER-SPECIFIC RISKS. Issuer-specific attributes may cause an investment held by the Fund to be more volatile than the market generally. The value of an individual security or particular type of security may be more volatile than the market as a whole and may perform differently from the value of the market as a whole. BABA operates in China, where the regulatory landscape is complex and subject to rapid changes. The Chinese government plays a significant role in the country’s economic policies. Sudden regulatory changes, monetary policy shifts, or government interventions could impact BABA’s business operations and investor confidence. For example, tightening regulations on fintech services, e-commerce pricing, or data security could increase operational costs and compliance burdens. The Chinese government has increased its regulatory scrutiny of large technology companies, implementing antitrust measures, data security regulations, and stricter financial oversight. Any additional government intervention could impose operational restrictions, fines, or business restructuring requirements on BABA. China has implemented strict data security laws, such as the Personal Information Protection Law, which impose compliance requirements on companies handling large volumes of consumer data. If BABA fails to comply, it could face fines, restrictions, or operational setbacks. The U.S. government has previously imposed sanctions on Chinese technology companies and BABA could face similar scrutiny in the future. Sanctions or restrictions on BABA or its subsidiaries (e.g., Ant Group) could impact revenue, growth prospects, and investor confidence. BABA competes with other Chinese e-commerce giants and large international companies. Price competition, innovation, and customer preferences could impact BABA’s market share and profitability. BABA’s core e-commerce business is heavily reliant on Chinese consumer spending, which is influenced by macroeconomic conditions, disposable income levels, and regulatory policies. A slowdown in economic growth or reduced consumer confidence in China could impact BABA’s revenue. A weakening Chinese economy, high youth unemployment, or declining consumer confidence could reduce BABA’s sales and earnings growth. BABA’s revenue growth has been impacted by regulatory fines, changes in consumer behavior, and increased investments in new business ventures. Any significant revenue slowdown could negatively affect the stock price. BABA reports its financial results in Chinese yuan, but its shares trade as American Depositary Shares in U.S. dollars. Changes in exchange rates between the Chinese yuan and U.S. dollar may impact the value of BABA’s stock, dividends, and reported earnings for U.S. investors.

 

ASIAN GEOPOLITICAL TENSIONS RISK. BABA has significant exposure to Asia as a result of its operations, supply chain and location of its customers. Asian geopolitical developments, such as trade disputes, territorial conflicts, regulatory changes, sanctions, military actions, or changes in diplomatic relations, could materially impact BABA’s business operations, financial performance and stock price. Tensions between major economies in the region, including but not limited to China, Taiwan, South Korea, Japan and India, as well as broader U.S.-Asia relations, may lead to increased market volatility, disruptions in trade, supply chain constraints, or restrictions on capital flows. Governments in these regions may impose tariffs, export controls, or other regulatory measures that could negatively affect certain industries, including technology, manufacturing, and consumer goods. Additionally, political instability, social unrest, or unexpected policy shifts could create further uncertainty for businesses operating in the region.

 

CONSUMER DISCRETIONARY COMPANIES RISK. The success of consumer product manufacturers and retailers is tied closely to the performance of domestic and international economies, interest rates, exchange rates, supply chains, competition, consumer confidence, changes in demographics and consumer preferences. Companies in the consumer discretionary sector depend heavily on disposable household income and consumer spending, and may be strongly affected by social trends and marketing campaigns. These companies may be subject to severe competition, which may have an adverse impact on their profitability.

 

DEPOSITARY SHARE RISK. BABA’s securities are structured as American Depositary Shares (“ADSs”). While ADSs provide U.S. investors with a convenient way to gain exposure to foreign equities, they are subject to unique risks that could impact their value and liquidity. ADSs are tied to the performance of the underlying foreign shares, which may be subject to risks related to the political, economic, and regulatory environment of the issuing company’s home country. Factors such as economic instability, foreign exchange controls and government intervention could impact the value of ADSs. While ADSs are denominated in U.S. dollars, the underlying foreign shares trade in a different currency. As a result, fluctuations in exchange rates between the U.S. dollar and the local currency of the foreign company could impact the value of the ADSs. A strengthening U.S. dollar may reduce the value of dividends or capital appreciation for ADS holders. ADSs are subject to both U.S. and foreign regulations. Changes in foreign securities laws, taxation policies, or reporting requirements could impact the ability of the depository bank to maintain ADS listings. Additionally, some foreign jurisdictions may impose restrictions on capital flows or repatriation of earnings, which could affect shareholder rights and returns. Foreign companies may follow different accounting standards and disclosure practices than U.S. companies. Differences in financial reporting, corporate governance, and regulatory oversight could make it more difficult for investors to evaluate the financial health and risks associated with ADS issuers.

 

INDIRECT INVESTMENT RISK. Alibaba Group Holding Limited is not affiliated with the Trust, the Fund, the Adviser, the Sub-Adviser or any affiliates thereof and is not involved with this offering in any way, and has no obligation to consider the Fund in taking any corporate actions that might affect the value of the Fund. The Trust, the Fund, the Adviser, the Sub-Adviser or any affiliate are not responsible for the performance of BABA and make no representation as to the performance of BABA. Investing in the Fund is not equivalent to investing in BABA. Fund shareholders will not have voting rights or rights to receive dividends or other distributions or any other rights with respect to BABA.

 

LARGE CAPITALIZATION COMPANIES RISK. Large capitalization companies may be less able than smaller capitalization companies to adapt to changing market conditions. Large capitalization companies may be more mature and subject to more limited growth potential compared with smaller capitalization companies. During different market cycles, the performance of large capitalization companies has trailed the overall performance of the broader securities markets.

 

NON-U.S. SECURITIES RISK. Non-U.S. securities are subject to higher volatility than securities of domestic issuers due to possible adverse political, social or economic developments, restrictions on foreign investment or exchange of securities, capital controls, lack of liquidity, currency exchange rates, excessive taxation, government seizure of assets, the imposition of sanctions by foreign governments, different legal or accounting standards, and less government supervision and regulation of securities exchanges in foreign countries.

 

RETAIL COMPANIES RISK. Companies involved in retail may be affected by the performance of the domestic and international economy, interest rates, rates of inflation, exchange rates, competition, consumer confidence and reputational damage. The success of companies involved in retail depends heavily on disposable household income and consumer spending, and changes in demographics and consumer preferences can affect the success of retail companies. Certain retail companies have historically been subject to significant seasonal and quarterly variations. The success of retail companies may be strongly affected by fads, marketing campaigns and other factors affecting supply and demand and a retail company’s success can be tied to its ability to anticipate changing consumer tastes. These companies may be subject to severe competition, which may have an adverse impact on their profitability. Certain business segments of retail companies are highly cyclical, which may cause the operating results of such retail companies to vary significantly. Retail companies may be dependent on outside financing, which may be difficult to obtain. Many of these companies are dependent on third party suppliers and distribution systems and purchase merchandise both directly from brand owners and indirectly from retailers and third-party suppliers. Such companies may also be dependent upon suppliers for the products used for their own brand name merchandise. Reliance on third party suppliers subjects retail companies to risks of delivery delays, price increases and receipt of nonconforming or poor quality merchandise. Retail companies may be unable to protect their intellectual property rights and may be liable for infringing the intellectual property rights of others. Changes in labor laws and other labor issues, such as increased labor costs, could adversely affect the financial performance of retail companies. If retail companies do not maintain the security of customer-related information, they could damage their reputations with customers, incur substantial costs and become subject to litigation, all of which could adversely affect the financial performance of such companies. The international operations of certain retail companies expose them to risks associated with instability and changes in economic and political conditions, foreign currency fluctuations, changes in foreign regulations, tariffs and trade disputes and other risks inherent to international business. Some of the companies in the Retail Index are engaged in other lines of business unrelated to retail, and they may experience problems with these lines of business which could adversely affect their operating results. The operating results of these companies may fluctuate as a result of these additional risks and events in the other lines of business. In addition, a company’s ability to engage in new activities may expose it to business risks with which it has less experience than it has with the business risks associated with its traditional businesses. Despite a company’s possible success in traditional retail activities, the other lines of business in which these companies are engaged may have an adverse effect on a company’s business or financial condition.

 

VARIABLE INTEREST ENTITY RISK. BABA, like many Chinese companies listed on foreign exchanges, uses a variable interest entity (“VIE”) structure to comply with China’s foreign ownership restrictions. Exposure to VIEs may pose additional risks because the investment is made in reference to an intermediary shell company that has entered into service and other contracts with the underlying Chinese operating company to provide investors with exposure to the operating company, but does not represent equity ownership in the operating company. As a result, such investment may limit the rights of an investor with respect to the underlying Chinese operating company. VIEs allow foreign shareholders to exert a degree of control over, and obtain economic benefits arising from, the operating company without formal legal ownership. However, the contractual arrangements between the shell company and the operating company may not be as effective in providing operational control as direct equity ownership, and a foreign investor's rights may be limited by, for example, actions of the Chinese government which could determine that the underlying contractual arrangements on which control of the VIE is based are invalid. The contractual arrangement on which the VIE structure is based would likely be subject to Chinese law and jurisdiction, which could raise questions about how recourse is sought. Investments through VIEs may be affected by conflicts of interest and duties between the legal owners of the VIE and the stockholders of the listed holding company, which could adversely impact the value of investments. VIEs are not formally recognized under Chinese law and investors face uncertainty about future actions by the Chinese government that could significantly affect the operating company's financial performance and the enforceability of the contractual arrangements underlying the VIE structure. Prohibitions of these structures by the Chinese government, or the inability to enforce such contracts, from which the shell company derives its value, would likely cause the VIE-structured holding(s) to suffer significant losses, and in turn, adversely affect the Fund's returns and net asset value.

NON-DIVERSIFICATION RISK. As a “non-diversified” fund, the Fund may hold a smaller number of portfolio securities than many other funds. To the extent the Fund invests in a relatively small number of issuers, a decline in the market value of a particular security held by the Fund may affect its value more than if it invested in a larger number of issuers. The value of the Fund Shares may be more volatile than the values of shares of more diversified funds.

Roundhill BRKB WeeklyPay™ ETF | MARKET RISK  
Prospectus [Line Items]  
Risk [Text Block]

MARKET RISK. Market risk is the risk that a particular investment, or Fund Shares in general, may fall in value. Securities are subject to market fluctuations caused by real or perceived adverse economic, political, and regulatory factors or market developments, changes in interest rates, disruptions to trade, impositions of tariffs and perceived trends in securities prices. Fund Shares could decline in value or underperform other investments. In addition, local, regional or global events such as war, acts of terrorism, market manipulation, government defaults, government shutdowns, regulatory actions, political changes, diplomatic developments, the imposition of sanctions and other similar measures, spread of infectious diseases or other public health issues, recessions, natural disasters, or other events could have a significant negative impact on the Fund and its investments. Any of such circumstances could have a materially negative impact on the value of Fund Shares, the liquidity of an investment, and may result in increased market volatility. During any such events, Fund Shares may trade at increased premiums or discounts to their net asset value, the bid/ask spread on Fund Shares may widen and the returns on investment may fluctuate.

Roundhill BRKB WeeklyPay™ ETF | LIQUIDITY RISK  
Prospectus [Line Items]  
Risk [Text Block]

LIQUIDITY RISK. The market for swap agreements that reference BRK/B shares may be subject to periods of illiquidity. During such times it may be difficult or impossible to buy or sell a position at the desired price. Market disruptions or volatility can also make it difficult to find a counterparty willing to transact at a reasonable price and sufficient size. Illiquid markets may cause losses, which could be significant. The large size of the positions which the Fund may acquire increases the risk of illiquidity, may make its positions more difficult to liquidate, and may increase the losses incurred while trying to do so. Such large positions also may impact the price of swap agreements on BRK/B shares.

Roundhill BRKB WeeklyPay™ ETF | ACTIVE MANAGEMENT RISK  
Prospectus [Line Items]  
Risk [Text Block]

ACTIVE MANAGEMENT RISK. The Fund is actively-managed and its performance reflects investment decisions that the Adviser and/or Sub-Adviser makes for the Fund. Such judgments about the Fund’s investments may prove to be incorrect. If the investments selected and the strategies employed by the Fund fail to produce the intended results, the Fund could underperform as compared to other funds with similar investment objectives and/or strategies, or could have negative returns.

Roundhill BRKB WeeklyPay™ ETF | ACTIVE MARKET RISK  
Prospectus [Line Items]

ACTIVE MARKET RISK. Although Fund Shares are listed for trading on the Exchange, there can be no assurance that an active trading market for Fund Shares will develop or be maintained. Fund Shares trade on the Exchange at market prices that may be below, at or above the Fund’s net asset value. Securities, including Fund Shares, are subject to market fluctuations and liquidity constraints that may be caused by such factors as economic, political, or regulatory developments, changes in interest rates, and/or perceived trends in securities prices. Fund Shares could decline in value or underperform other investments.

Roundhill BRKB WeeklyPay™ ETF | ASSET CLASS RISK

CONCENTRATION RISK. The Fund is susceptible to an increased risk of loss, including losses due to adverse events that affect the Fund’s investments more than the market as a whole, to the extent that the Fund’s investments are concentrated in investments that provide exposure to BRK/B and the industry to which it is assigned.

Roundhill BRKB WeeklyPay™ ETF | COUNTERPARTY RISK  
Prospectus [Line Items]  
Risk [Text Block]

COUNTERPARTY RISK. Fund transactions involving a counterparty are subject to the risk that the counterparty will not fulfill its obligation to the Fund. Counterparty risk may arise because of the counterparty’s financial condition (i.e., financial difficulties, bankruptcy, or insolvency), market activities and developments, or other reasons, whether foreseen or not. A counterparty’s inability to fulfill its obligation may result in significant financial loss to the Fund. The Fund may be unable to recover its investment from the counterparty or may obtain a limited recovery, and/or recovery may be delayed.

CREDIT RISK. An issuer or other obligated party of a debt security may be unable or unwilling to make dividend, interest and/or principal payments when due. In addition, the value of a debt security may decline because of concerns about the issuer’s ability or unwillingness to make such payments.

Roundhill BRKB WeeklyPay™ ETF | CURRENT MARKET CONDITIONS RISK  
Prospectus [Line Items]  
Risk [Text Block]

CURRENT MARKET CONDITIONS RISK. Current market conditions risk is the risk that a particular investment, or Fund Shares in general, may fall in value due to current market conditions. As a means to fight inflation, which remains at elevated levels, the Federal Reserve and certain foreign central banks have raised interest rates; however, the Federal Reserve has recently lowered interest rates and may continue to do so. U.S. regulators have proposed several changes to market and issuer regulations which would directly impact the Fund, and any regulatory changes could adversely impact the Fund’s ability to achieve its investment strategies or make certain investments. Recent and potential future bank failures could result in disruption to the broader banking industry or markets generally and reduce confidence in financial institutions and the economy as a whole, which may also heighten market volatility and reduce liquidity. Additionally, challenges in commercial real estate markets, including rising interest rates, declining valuations and increasing vacancies, could have a broader impact on financial markets. The ongoing adversarial political climate in the United States, as well as political and diplomatic events both domestic and abroad, have and may continue to have an adverse impact the U.S. regulatory landscape, markets and investor behavior, which could have a negative impact on the Fund’s investments and operations. The change in administration resulting from the 2024 United States national elections could result in significant impacts to international trade relations, tax and immigration policies, and other aspects of the national and international political and financial landscape, which could affect, among other things, inflation and the securities markets generally. Other unexpected political, regulatory and diplomatic events within the U.S. and abroad may affect investor and consumer confidence and may adversely impact financial markets and the broader economy. For example, ongoing armed conflicts between Russia and Ukraine in Europe and among Israel, Iran, Hamas and other militant groups in the Middle East, have caused and could continue to cause significant market disruptions and volatility within the markets in Russia, Europe, the Middle East and the United States. The hostilities and sanctions resulting from those hostilities have and could continue to have a significant impact on certain Fund investments as well as Fund performance and liquidity. The economies of the United States and its trading partners, as well as the financial markets generally, may be adversely impacted by trade disputes, including the imposition of tariffs, and other matters. For example, the United States has imposed trade barriers and restrictions on China. In addition, the Chinese government is engaged in a longstanding dispute with Taiwan, continually threatening an invasion. If the political climate between the United States and China does not improve or continues to deteriorate, if China were to attempt invading Taiwan, or if other geopolitical conflicts develop or worsen, economies, markets and individual securities may be adversely affected, and the value of the Fund’s assets may go down. A public health crisis and the ensuing policies enacted by governments and central banks may cause significant volatility and uncertainty in global financial markets, negatively impacting global growth prospects. As the COVID-19 global pandemic illustrated, such events may affect certain geographic regions, countries, sectors and industries more significantly than others. Advancements in technology may also adversely impact markets and the overall performance of the Fund. For instance, the economy may be significantly impacted by the advanced development and increased regulation of artificial intelligence. Additionally, cyber security breaches of both government and non-government entities could have negative impacts on infrastructure and the ability of such entities, including the Fund, to operate properly. These events, and any other future events, may adversely affect the prices and liquidity of the Fund’s portfolio investments and could result in disruptions in the trading markets.

Roundhill BRKB WeeklyPay™ ETF | CYBERSECURITY RISK  
Prospectus [Line Items]  
Risk [Text Block]

CYBERSECURITY RISK. Failures or breaches of the electronic systems of the Fund, the Fund’s adviser, sub-adviser, distributor and other service providers, market makers, Authorized Participants or the issuers of securities in which the Fund invests have the ability to cause disruptions, negatively impact the Fund’s business operations and/or potentially result in financial losses to the Fund and its shareholders. While the Fund has established business continuity plans and risk management systems seeking to address system breaches or failures, there are inherent limitations in such plans and systems. Furthermore, the Fund cannot control the cybersecurity plans and systems of the Fund’s other service providers, market makers, Authorized Participants or issuers of securities in which the Fund invests.

Roundhill BRKB WeeklyPay™ ETF | DEBT SECURITIES RISK  
Prospectus [Line Items]  
Risk [Text Block]

DEBT SECURITIES RISK. Investments in debt securities subject the holder to the credit risk of the issuer. Credit risk refers to the possibility that the issuer or other obligor of a security will not be able or willing to make payments of interest and principal when due. Generally, the value of debt securities will change inversely with changes in interest rates. To the extent that interest rates rise, certain underlying obligations may be paid off substantially slower than originally anticipated and the value of those securities may fall sharply. During periods of falling interest rates, the income received by the Fund may decline. If the principal on a debt security is prepaid before expected, the prepayments of principal may have to be reinvested in obligations paying interest at lower rates. Debt securities generally do not trade on a securities exchange making them generally less liquid and more difficult to value than common stock.

Roundhill BRKB WeeklyPay™ ETF | DERIVATIVES RISK  
Prospectus [Line Items]  
Risk [Text Block]

DERIVATIVES RISK. The use of derivative instruments involves risks different from, or possibly greater than, the risks associated with investing directly in securities and other traditional investments. These risks include: (i) the risk that the counterparty to a derivative transaction may not fulfill its contractual obligations; (ii) risk of mispricing or improper valuation; and (iii) the risk that changes in the value of the derivative may not correlate perfectly with the underlying asset. Derivative prices are highly volatile and may fluctuate substantially during a short period of time. Such prices are influenced by numerous factors that affect the markets, including, but not limited to: changing supply and demand relationships; government programs and policies; national and international political and economic events, changes in interest rates, inflation and deflation and changes in supply and demand relationships. Trading derivative instruments involves risks different from, or possibly greater than, the risks associated with investing directly in securities. Derivative contracts ordinarily have leverage inherent in their terms. The use of leverage may cause the Fund to liquidate portfolio positions when it would not be advantageous to do so in order to satisfy its obligations or to meet regulatory or contractual requirements for derivatives. The use of derivatives can magnify potential for gain or loss and, therefore, amplify the effects of market volatility on share price.

Roundhill BRKB WeeklyPay™ ETF | DISTRIBUTION TAX RISK  
Prospectus [Line Items]

DISTRIBUTION TAX RISK. The Fund currently expects to make distributions on a weekly basis. Such frequent distributions may expose investors to increased tax liabilities. However, these distributions may exceed the Fund’s income and gains for the Fund’s taxable year. Distributions in excess of the Fund’s current and accumulated earnings and profits will be treated as a return of capital. A return of capital distribution generally will not be taxable but will reduce the shareholder’s cost basis and will result in a higher capital gain or lower capital loss when those Fund Shares on which the distribution was received are sold. Once a Fund shareholder’s cost basis is reduced to zero, further distributions will be treated as capital gain if the Fund shareholder holds Fund Shares as capital assets. Additionally, any capital returned through distributions will be distributed after payment of Fund fees and expenses. Because a portion of the Fund’s distributions may consist of return of capital, the Fund may not be an appropriate investment for investors who do not want their principal investment in the Fund to decrease over time or who do not wish to receive return of capital in a given period. In the event that a shareholder purchases Fund Shares shortly before a distribution by the Fund, the entire distribution may be taxable to the shareholder even though a portion of the distribution effectively represents a return of the purchase price.

Roundhill BRKB WeeklyPay™ ETF | ETF RISK  
Prospectus [Line Items]  
Risk [Text Block]

ETF RISK. The Fund may invest in ETFs. The value of an ETF held by the Fund will fluctuate over time based on fluctuations in the values of the assets held by the ETF, which may be affected by changes in general economic conditions, expectations for future growth and profits, interest rates and the supply and demand for those assets. When the Fund invests in an ETF, it will bear a proportionate share of the ETF’s expenses. Brokerage, tax and other expenses may negatively impact the performance of the ETF and, in turn, the value of the Fund Shares. An ETF that tracks an index may not exactly match the performance of the index due to cash drag, differences between the portfolio of the ETF and the components of the index, expenses and other factors.

Roundhill BRKB WeeklyPay™ ETF | INFLATION RISK

INFLATION RISK. Inflation risk is the risk that the value of assets or income from investments will be less in the future as inflation decreases the value of money. As inflation increases, the present value of the Fund’s assets and distributions may decline. This risk is more prevalent with respect to fixed income securities held by the Fund.

Roundhill BRKB WeeklyPay™ ETF | Interest Rate Risk [Member]  
Prospectus [Line Items]  
Risk [Text Block]

INTEREST RATE RISK. Interest rate risk is the risk that the value of the debt securities in the Fund’s portfolio will decline because of rising market interest rates. Interest rate risk is generally lower for shorter term debt securities and higher for longer-term debt securities. Duration is a reasonably accurate measure of a debt security’s price sensitivity to changes in interest rates and a common measure of interest rate risk. Duration measures a debt security’s expected life on a present value basis, taking into account the debt security’s yield, interest payments and final maturity. In general, duration represents the expected percentage change in the value of a security for an immediate 1% change in interest rates. For example, the price of a debt security with a three-year duration would be expected to drop by approximately 3% in response to a 1% increase in interest rates. Therefore, prices of debt securities with shorter durations tend to be less sensitive to interest rate changes than debt securities with longer durations. As the value of a debt security changes over time, so will its duration.

Roundhill BRKB WeeklyPay™ ETF | LEGISLATION AND LITIGATION RISK  
Prospectus [Line Items]  
Risk [Text Block]

LEGISLATION AND LITIGATION RISK. Legislation or litigation that affects the value of assets or securities held by the Fund may reduce the value of the Fund. From time to time, various legislative initiatives are proposed that may have a negative impact on certain assets or securities in which the Fund invests. In addition, litigation regarding any of the assets or securities owned by the Fund may negatively impact the value of the Shares. Such legislation or litigation may cause the Fund to lose value or may result in higher portfolio turnover if the Adviser determines to sell such a holding.

Roundhill BRKB WeeklyPay™ ETF | LEVERAGE RISK  
Prospectus [Line Items]  
Risk [Text Block]

LEVERAGE RISK. The Fund obtains investment exposure in excess of its net assets by utilizing leverage and may lose more money in market conditions that are adverse to its investment objectives than a fund that does not utilize leverage. An investment in the Fund is exposed to the risk that a decline in the weekly performance of shares of BRK/B will be magnified. This means that an investment in the Fund will be reduced by an amount equal to 1.2% for every 1% weekly decline in the market value of the BRK/B shares, not including the costs of financing leverage and other operating expenses, which would further reduce its value. The Fund could theoretically lose an amount greater than its net assets in the event the market value of BRK/B shares decline more than 83.33% over a calendar week. Leverage will also have the effect of magnifying any differences in the Fund’s correlation with BRK/B shares.

Roundhill BRKB WeeklyPay™ ETF | MONEY MARKET INSTRUMENTS RISK  
Prospectus [Line Items]  
Risk [Text Block]

MONEY MARKET INSTRUMENTS RISK. The value of money market instruments may be affected by changing interest rates and by changes in the credit ratings of the investments. If a significant amount of the Fund’s assets are invested in money market instruments, it will be more difficult for the Fund to achieve its investment objectives. An investment in a money market fund is not insured or guaranteed by the FDIC or any other government agency. It is possible to lose money by investing in a money market fund.

Roundhill BRKB WeeklyPay™ ETF | OPERATIONAL RISK  
Prospectus [Line Items]  
Risk [Text Block]

OPERATIONAL RISK. The Fund is subject to risks arising from various operational factors, including, but not limited to, human error, processing and communication errors, errors of the Fund’s service providers, counterparties or other third-parties, failed or inadequate processes and technology or systems failures. The Fund relies on third-parties for a range of services, including custody. Any delay or failure relating to engaging or maintaining such service providers may affect the Fund’s ability to meet its investment objectives. Although the Fund and the Adviser seek to reduce these operational risks through controls and procedures, there is no way to completely protect against such risks.

Roundhill BRKB WeeklyPay™ ETF | STRUCTURAL ETF RISKS  
Prospectus [Line Items]  
Risk [Text Block]

STRUCTURAL ETF RISKS. The Fund is an ETF. Accordingly, it is subject to certain risks associated with its unique structure.

 

Market Participants Risk. Only an Authorized Participant may engage in creation or redemption transactions directly with the Fund, and none of those Authorized Participants is obligated to engage in creation and/or redemption transactions. The Fund has a limited number of institutions that may act as Authorized Participants on an agency basis (i.e., on behalf of other market participants). To the extent that Authorized Participants exit the business or are unable to proceed with creation or redemption orders with respect to the Fund and no other Authorized Participant is able to step forward to create or redeem, Fund Shares may be more likely to trade at a premium or discount to NAV and possibly face trading halts or delisting. The Fund may also rely on a small number of third-party market makers to provide a market for the purchase and sale of Fund Shares but such market makers are under no obligation to do so. Decisions by Authorized Participants or market makers to reduce their role or step away from these activities in times of market stress could inhibit the effectiveness of the arbitrage process in maintaining the relationship between the underlying values of the Fund’s portfolio securities and the Fund’s market price. Any trading halt or other problem relating to the trading activity of these market makers or any issues disrupting the Authorized Participants’ ability to proceed with creation and/or redemption orders could result in a dramatic change in the spread between the Fund’s net asset value and the price at which Fund Shares are trading on the Exchange, which could result in a decrease in value of Fund Shares. This reduced effectiveness could result in Fund Shares trading at a premium or discount to net asset value and also in greater than normal intraday bid-ask spreads Fund Shares.

 

Cash Transactions Risk. The Fund currently expects to effect a significant portion of its creations and redemptions for cash, rather than in-kind securities. Paying redemption proceeds in cash rather than through in-kind delivery of portfolio securities may require the Fund to dispose of or sell portfolio securities or other assets at an inopportune time to obtain the cash needed to meet redemption orders. This may cause the Fund to sell a security and recognize a capital gain or loss that might not have been incurred if it had made a redemption in-kind. As a result, the Fund may pay out higher or lower annual capital gains distributions than ETFs that redeem in-kind. The use of cash creations and redemptions may also cause the Fund’s Shares to trade in the market at greater bid-ask spreads or greater premiums or discounts to the Fund’s NAV. Furthermore, the Fund may not be able to execute cash transactions for creation and redemption purposes at the same price used to determine the Fund’s NAV. To the extent that the maximum additional charge for creation or redemption transactions is insufficient to cover the execution shortfall, the Fund’s performance could be negatively impacted.

 

Costs of Buying and Selling Fund Shares. Due to the costs of buying or selling Fund Shares, including brokerage commissions imposed by brokers and bid/ask spreads, frequent trading of Fund Shares may significantly reduce investment results and an investment in Fund Shares may not be advisable for investors who anticipate regularly making small investments.

 

Premium/Discount Risk. As with all ETFs, Fund Shares may be bought and sold in the secondary market at market prices. The trading prices of Fund Shares in the secondary market may differ from the Fund’s daily net asset value per share and there may be times when the market price of the shares is more than the net asset value per share (premium) or less than the net asset value per share (discount). If a shareholder purchases Fund Shares at a time when the market price is at a premium to the net asset value or sells Fund Shares at a time when the market price is at a discount to the net asset value, the shareholder may pay more for, or receive less than, the underlying value of the Fund Shares, respectively. This risk is heightened in times of market volatility or periods of steep market declines.

 

Trading Risks. Although Fund Shares are listed for trading on the Exchange and may be traded on U.S. exchanges other than the Exchange, there can be no assurance that Fund Shares will trade with any volume, or at all, on any stock exchange. In stressed market conditions, the liquidity of Fund Shares may begin to mirror the liquidity of the Fund’s underlying portfolio holdings, which can be significantly less liquid than Fund Shares. Trading in Fund Shares on the Exchange may be halted due to market conditions or for reasons that, in the view of the Exchange, make trading in Fund Shares inadvisable. In addition, trading in Fund Shares on the Exchange is subject to trading halts caused by extraordinary market volatility pursuant to the Exchange’s “circuit breaker” rules. There can be no assurance that the requirements of the Exchange necessary to maintain the listing of the Fund will continue to be met or will remain unchanged.

Prospectus [Line Items]  
Risk [Text Block]

U.S. GOVERNMENT SECURITIES RISK. U.S. government securities are subject to interest rate risk but generally do not involve the credit risks associated with investments in other types of debt securities. As a result, the yields available from U.S. government securities are generally lower than the yields available from other debt securities. U.S. government securities are guaranteed only as to the timely payment of interest and the payment of principal when held to maturity.

Roundhill BRKB WeeklyPay™ ETF | VALUATION RISK  
Prospectus [Line Items]  
Risk [Text Block]

VALUATION RISK. The Fund may hold securities or other assets that may be valued on the basis of factors other than market quotations. This may occur because the asset or security does not trade on a centralized exchange, or in times of market turmoil or reduced liquidity. There are multiple methods that can be used to value a portfolio holding when market quotations are not readily available. The value established for any portfolio holding at a point in time might differ from what would be produced using a different methodology or if it had been priced using market quotations. Portfolio holdings that are valued using techniques other than market quotations, including “fair valued” assets or securities, may be subject to greater fluctuation in their valuations from one day to the next than if market quotations were used. In addition, there is no assurance that the Fund could sell or close out a portfolio position for the value established for it at any time, and it is possible that the Fund would incur a loss because a portfolio position is sold or closed out at a discount to the valuation established by the Fund at that time. The Fund’s ability to value investments may be impacted by technological issues or errors by pricing services or other third-party service providers.

Roundhill BRKB WeeklyPay™ ETF | EQUITY SECURITIES RISK  
Prospectus [Line Items]  
Risk [Text Block]

EQUITY SECURITIES RISK. Equity securities are subject to changes in value, and their values may be more volatile than those of other asset classes. Equity securities prices fluctuate for several reasons, including changes in investors’ perceptions of the financial condition of an issuer or the general condition of the relevant equity market, such as market volatility, or when political or economic events affecting an issuer occur. Common stock prices may be particularly sensitive to rising interest rates, as the cost of capital rises and borrowing costs increase. Common stocks generally subject their holders to more risks than preferred stocks and debt securities because common stockholders’ claims are subordinated to those of holders of preferred stocks and debt securities upon the bankruptcy of the issuer.

Roundhill BRKB WeeklyPay™ ETF | SWAP AGREEMENTS RISK  
Prospectus [Line Items]  
Risk [Text Block]

SWAP AGREEMENTS RISK. The Fund will utilize swap agreements to derive its exposure to shares of BRK/B. Swap agreements may involve greater risks than direct investment in securities as they may be leveraged and are subject to credit risk, counterparty risk and valuation risk. A swap agreement could result in losses if the underlying reference or asset does not perform as anticipated. In addition, many swaps trade over-the-counter and may be considered illiquid. It may not be possible for the Fund to liquidate a swap position at an advantageous time or price, which may result in significant losses.

Roundhill BRKB WeeklyPay™ ETF | REGULATED INVESTMENT COMPANY TAX RISKS  
Prospectus [Line Items]  
Risk [Text Block]

REGULATED INVESTMENT COMPANY TAX RISKS. The Fund intends to qualify annually and to elect to be treated as a regulated investment company under the Internal Revenue Code of 1986, as amended (the “Code”). To qualify for the favorable U.S. federal income tax treatment generally accorded to regulated investment companies, the Fund must, among other things, (i) derive in each taxable year at least 90% of its gross income from dividends, interest, payments with respect to securities loans and gains from the sale or other disposition of stock, securities or foreign currencies or other income derived with respect to its business of investing in such stock, securities or currencies, or net income derived from interests in certain publicly traded partnerships; (ii) diversify its holdings so that, at the end of each quarter of the taxable year, (a) at least 50% of the market value of the Fund’s assets is represented by cash and cash items (including receivables), U.S. government securities, the securities of other regulated investment companies and other securities, with such other securities of any one issuer generally limited for the purposes of this calculation to an amount not greater than 5% of the value of the Fund’s total assets and not greater than 10% of the outstanding voting securities of such issuer, and (b) not more than 25% of the value of its total assets is invested in the securities (other than U.S. government securities or the securities of other regulated investment companies) of any one issuer, or two or more issuers which the Fund controls which are engaged in the same, similar or related trades or businesses, or the securities of one or more of certain publicly traded partnerships; and (iii) distribute at least 90% of its investment company taxable income (which includes, among other items, dividends, interest and net short-term capital gains in excess of net long-term capital losses) and at least 90% of its net tax-exempt interest income each taxable year. There are certain exceptions for failure to qualify if the failure is for reasonable cause or is de minimis, and certain corrective action is taken and certain tax payments are made by the Fund.

 

If the Fund were to fail to meet the qualifying income test or asset diversification test and fail to qualify as a RIC, it would be taxed in the same manner as an ordinary corporation, and distributions to its shareholders would not be deductible by the Fund in computing its taxable income, which would adversely affect the Fund’s performance.

Roundhill BRKB WeeklyPay™ ETF | LARGE SHAREHOLDER RISK  
Prospectus [Line Items]  
Risk [Text Block]

LARGE SHAREHOLDER RISK. Certain shareholders, including affiliated funds advised by the Adviser, may from time to time own a significant portion of the Fund’s shares. In addition, a third-party investor, the Adviser or an affiliate of the Adviser (“Affiliate”), an authorized participant, a market maker, or another entity may invest in the Fund and hold its investment for a limited period solely to facilitate the commencement of the Fund or to help the Fund achieve a specified size or scale. There can be no assurance that any large shareholder will not redeem its investment, that the size of the Fund will be maintained at such levels, or that the Fund will continue to meet applicable listing requirements. Redemptions by large shareholders could have a significant negative impact on the Fund. In addition, transactions by large shareholders may account for a large percentage of the trading volume on the Fund’s listing exchange and may, therefore, have a material upward or downward effect on the market price of the shares.

 

To the extent that a significant percentage of the Fund’s shares are owned or controlled by a small number of account shareholders (or a single account shareholder), including funds or accounts over which the Adviser or an Affiliate has investment discretion, the Fund is subject to the risk that those shareholders may purchase or redeem Fund shares in significant amounts rapidly or unexpectedly, including as a result of an asset allocation decision made by the Adviser or an Affiliate. This may adversely affect the Fund’s performance if the Adviser is forced to sell portfolio securities or invest cash when it would not otherwise choose to do so. Redemptions of a large number of shares may affect the liquidity of the Fund’s portfolio, increase the Fund’s transaction costs, and accelerate the realization of taxable income and/or gains. In addition, a large redemption could result in the Fund’s current expenses being allocated over a smaller asset base, leading to an increase in the Fund’s gross expense ratio. Large purchases of the Fund’s shares may also adversely affect the Fund’s performance to the extent that the Fund is delayed in investing new cash or otherwise maintains a larger cash position than it ordinarily would, particularly if the Fund accepts cash for an order for the purchase of creation units of the Fund’s shares.

Roundhill BRKB WeeklyPay™ ETF | BRK/B INVESTING RISKS  
Prospectus [Line Items]  
Risk [Text Block]

BRK/B INVESTING RISKS. The Fund will have significant exposure to BRK/B through its investments in swap agreements that utilize BRK/B as the reference asset. Accordingly, the Fund will subject to the risks of BRK/B, set forth below.

 

BRK/B ISSUER-SPECIFIC RISKS. Issuer-specific attributes may cause an investment held by the Fund to be more volatile than the market generally. The value of an individual security or particular type of security may be more volatile than the market as a whole and may perform differently from the value of the market as a whole. BRK/B operates a vast portfolio of businesses across multiple industries, making it challenging to efficiently manage, allocate capital, and respond swiftly to industry-specific disruptions. While diversification can mitigate risks, downturns in multiple industries simultaneously, such as insurance losses from natural disasters, declines in consumer spending affecting retail and manufacturing, or regulatory changes impacting financial services, could lead to broad-based losses. BRK/B’s core business includes insurance subsidiaries. The company is exposed to underwriting losses from catastrophic events (e.g., hurricanes, earthquakes, pandemics) that could lead to significant claims payouts, reducing profitability. BRK/B has long been associated with Warren Buffett’s leadership and investment philosophy. Although a succession plan is in place, the transition to new leadership could impact investor confidence and long-term strategic decision-making. BRK/B allows its subsidiaries to operate with significant autonomy. While this reduces operational bureaucracy, it also increases the risk of inefficient capital allocation, governance challenges, and potential mismanagement at the subsidiary level. Many of BRK/B’s businesses, including rail transportation, manufacturing, and retail, are cyclical and dependent on economic growth. A slowdown in economic activity could reduce revenue across multiple segments. Declining consumer spending, supply chain disruptions, or global trade uncertainties could impact BRK/B’s subsidiaries and investment holdings.

 

FINANCIAL COMPANIES RISK. Companies in the financials sector are subject to extensive governmental regulation and intervention, which may adversely affect the scope of their activities, the prices they can charge, the amount of capital and liquid assets they must maintain and, potentially, their size. Governmental regulation may change frequently and may have significant adverse consequences for companies in the financials sector, including effects not intended by such regulation. Increased risk taking by financial companies may also result in greater overall risk in the U.S. and global financials sector. The impact of changes in capital requirements, or recent or future regulation in various countries, on any individual financial company or on the financials sector as a whole cannot be predicted.

 

Certain risks may impact the value of investments in the financials sector more severely than those of investments outside this sector, including the risks associated with companies that operate with substantial financial leverage. Companies in the financials sector are exposed directly to the credit risk of their borrowers and counterparties, who may be leveraged to an unknown degree, including through swaps and other derivatives products. Financial services companies may have significant exposure to the same borrowers and counterparties, with the result that a borrower’s or counterparty’s inability to meet its obligations to one company may affect other companies with exposure to the same borrower or counterparty. This interconnectedness of risk may result in significant negative impacts to companies with direct exposure to the defaulting counterparty as well as adverse cascading effects in the markets and the financials sector generally. Companies in the financials sector may also be adversely affected by increases in interest rates and loan losses, decreases in the availability of money or asset valuations, credit rating downgrades, adverse public perception and adverse conditions in other related markets. Insurance companies, in particular, may be subject to severe price competition and/or rate regulation, which may have an adverse impact on their profitability. The financials sector is particularly sensitive to fluctuations in interest rates. The financials sector is also a target for cyberattacks. Cybersecurity incidents and technology malfunctions and failures have become increasingly frequent and have caused significant losses to companies in this sector, which may negatively impact the Fund. The extent to which the Fund may invest in a company that engages in securities-related activities or banking is limited by applicable law.

 

INDIRECT INVESTMENT RISK. Berkshire Hathaway Inc. is not affiliated with the Trust, the Fund, the Adviser, the Sub-Adviser or any affiliates thereof and is not involved with this offering in any way, and has no obligation to consider the Fund in taking any corporate actions that might affect the value of the Fund. The Trust, the Fund, the Adviser, the Sub-Adviser or any affiliate are not responsible for the performance of BRK/B and make no representation as to the performance of BRK/B. Investing in the Fund is not equivalent to investing in BRK/B. Fund shareholders will not have voting rights or rights to receive dividends or other distributions or any other rights with respect to BRK/B.

 

LARGE CAPITALIZATION COMPANIES RISK. Large capitalization companies may be less able than smaller capitalization companies to adapt to changing market conditions. Large capitalization companies may be more mature and subject to more limited growth potential compared with smaller capitalization companies. During different market cycles, the performance of large capitalization companies has trailed the overall performance of the broader securities markets.

 

UNITED STATES RISK. Certain changes in the U.S. economy, such as when the U.S. economy weakens or when its financial markets decline, may have an adverse effect on the securities to which the Fund has exposure.

NON-DIVERSIFICATION RISK. As a “non-diversified” fund, the Fund may hold a smaller number of portfolio securities than many other funds. To the extent the Fund invests in a relatively small number of issuers, a decline in the market value of a particular security held by the Fund may affect its value more than if it invested in a larger number of issuers. The value of the Fund Shares may be more volatile than the values of shares of more diversified funds.

Roundhill COST WeeklyPay™ ETF | MARKET RISK  
Prospectus [Line Items]  
Risk [Text Block]

MARKET RISK. Market risk is the risk that a particular investment, or Fund Shares in general, may fall in value. Securities are subject to market fluctuations caused by real or perceived adverse economic, political, and regulatory factors or market developments, changes in interest rates, disruptions to trade, impositions of tariffs and perceived trends in securities prices. Fund Shares could decline in value or underperform other investments. In addition, local, regional or global events such as war, acts of terrorism, market manipulation, government defaults, government shutdowns, regulatory actions, political changes, diplomatic developments, the imposition of sanctions and other similar measures, spread of infectious diseases or other public health issues, recessions, natural disasters, or other events could have a significant negative impact on the Fund and its investments. Any of such circumstances could have a materially negative impact on the value of Fund Shares, the liquidity of an investment, and may result in increased market volatility. During any such events, Fund Shares may trade at increased premiums or discounts to their net asset value, the bid/ask spread on Fund Shares may widen and the returns on investment may fluctuate.

Roundhill COST WeeklyPay™ ETF | LIQUIDITY RISK  
Prospectus [Line Items]  
Risk [Text Block]

LIQUIDITY RISK. The market for swap agreements that reference COST shares may be subject to periods of illiquidity. During such times it may be difficult or impossible to buy or sell a position at the desired price. Market disruptions or volatility can also make it difficult to find a counterparty willing to transact at a reasonable price and sufficient size. Illiquid markets may cause losses, which could be significant. The large size of the positions which the Fund may acquire increases the risk of illiquidity, may make its positions more difficult to liquidate, and may increase the losses incurred while trying to do so. Such large positions also may impact the price of swap agreements on COST shares.

Roundhill COST WeeklyPay™ ETF | ACTIVE MANAGEMENT RISK  
Prospectus [Line Items]  
Risk [Text Block]

ACTIVE MANAGEMENT RISK. The Fund is actively-managed and its performance reflects investment decisions that the Adviser and/or Sub-Adviser makes for the Fund. Such judgments about the Fund’s investments may prove to be incorrect. If the investments selected and the strategies employed by the Fund fail to produce the intended results, the Fund could underperform as compared to other funds with similar investment objectives and/or strategies, or could have negative returns.

Roundhill COST WeeklyPay™ ETF | ACTIVE MARKET RISK  
Prospectus [Line Items]

ACTIVE MARKET RISK. Although Fund Shares are listed for trading on the Exchange, there can be no assurance that an active trading market for Fund Shares will develop or be maintained. Fund Shares trade on the Exchange at market prices that may be below, at or above the Fund’s net asset value. Securities, including Fund Shares, are subject to market fluctuations and liquidity constraints that may be caused by such factors as economic, political, or regulatory developments, changes in interest rates, and/or perceived trends in securities prices. Fund Shares could decline in value or underperform other investments.

Roundhill COST WeeklyPay™ ETF | ASSET CLASS RISK

CONCENTRATION RISK. The Fund is susceptible to an increased risk of loss, including losses due to adverse events that affect the Fund’s investments more than the market as a whole, to the extent that the Fund’s investments are concentrated in investments that provide exposure to COST and the industry to which it is assigned.

Roundhill COST WeeklyPay™ ETF | COUNTERPARTY RISK  
Prospectus [Line Items]  
Risk [Text Block]

COUNTERPARTY RISK. Fund transactions involving a counterparty are subject to the risk that the counterparty will not fulfill its obligation to the Fund. Counterparty risk may arise because of the counterparty’s financial condition (i.e., financial difficulties, bankruptcy, or insolvency), market activities and developments, or other reasons, whether foreseen or not. A counterparty’s inability to fulfill its obligation may result in significant financial loss to the Fund. The Fund may be unable to recover its investment from the counterparty or may obtain a limited recovery, and/or recovery may be delayed.

CREDIT RISK. An issuer or other obligated party of a debt security may be unable or unwilling to make dividend, interest and/or principal payments when due. In addition, the value of a debt security may decline because of concerns about the issuer’s ability or unwillingness to make such payments.

Roundhill COST WeeklyPay™ ETF | CURRENT MARKET CONDITIONS RISK  
Prospectus [Line Items]  
Risk [Text Block]

CURRENT MARKET CONDITIONS RISK. Current market conditions risk is the risk that a particular investment, or Fund Shares in general, may fall in value due to current market conditions. As a means to fight inflation, which remains at elevated levels, the Federal Reserve and certain foreign central banks have raised interest rates; however, the Federal Reserve has recently lowered interest rates and may continue to do so. U.S. regulators have proposed several changes to market and issuer regulations which would directly impact the Fund, and any regulatory changes could adversely impact the Fund’s ability to achieve its investment strategies or make certain investments. Recent and potential future bank failures could result in disruption to the broader banking industry or markets generally and reduce confidence in financial institutions and the economy as a whole, which may also heighten market volatility and reduce liquidity. Additionally, challenges in commercial real estate markets, including rising interest rates, declining valuations and increasing vacancies, could have a broader impact on financial markets. The ongoing adversarial political climate in the United States, as well as political and diplomatic events both domestic and abroad, have and may continue to have an adverse impact the U.S. regulatory landscape, markets and investor behavior, which could have a negative impact on the Fund’s investments and operations. The change in administration resulting from the 2024 United States national elections could result in significant impacts to international trade relations, tax and immigration policies, and other aspects of the national and international political and financial landscape, which could affect, among other things, inflation and the securities markets generally. Other unexpected political, regulatory and diplomatic events within the U.S. and abroad may affect investor and consumer confidence and may adversely impact financial markets and the broader economy. For example, ongoing armed conflicts between Russia and Ukraine in Europe and among Israel, Iran, Hamas and other militant groups in the Middle East, have caused and could continue to cause significant market disruptions and volatility within the markets in Russia, Europe, the Middle East and the United States. The hostilities and sanctions resulting from those hostilities have and could continue to have a significant impact on certain Fund investments as well as Fund performance and liquidity. The economies of the United States and its trading partners, as well as the financial markets generally, may be adversely impacted by trade disputes, including the imposition of tariffs, and other matters. For example, the United States has imposed trade barriers and restrictions on China. In addition, the Chinese government is engaged in a longstanding dispute with Taiwan, continually threatening an invasion. If the political climate between the United States and China does not improve or continues to deteriorate, if China were to attempt invading Taiwan, or if other geopolitical conflicts develop or worsen, economies, markets and individual securities may be adversely affected, and the value of the Fund’s assets may go down. A public health crisis and the ensuing policies enacted by governments and central banks may cause significant volatility and uncertainty in global financial markets, negatively impacting global growth prospects. As the COVID-19 global pandemic illustrated, such events may affect certain geographic regions, countries, sectors and industries more significantly than others. Advancements in technology may also adversely impact markets and the overall performance of the Fund. For instance, the economy may be significantly impacted by the advanced development and increased regulation of artificial intelligence. Additionally, cyber security breaches of both government and non-government entities could have negative impacts on infrastructure and the ability of such entities, including the Fund, to operate properly. These events, and any other future events, may adversely affect the prices and liquidity of the Fund’s portfolio investments and could result in disruptions in the trading markets.

Roundhill COST WeeklyPay™ ETF | CYBERSECURITY RISK

Risk [Text Block]

CYBERSECURITY RISK. Failures or breaches of the electronic systems of the Fund, the Fund’s adviser, sub-adviser, distributor and other service providers, market makers, Authorized Participants or the issuers of securities in which the Fund invests have the ability to cause disruptions, negatively impact the Fund’s business operations and/or potentially result in financial losses to the Fund and its shareholders. While the Fund has established business continuity plans and risk management systems seeking to address system breaches or failures, there are inherent limitations in such plans and systems. Furthermore, the Fund cannot control the cybersecurity plans and systems of the Fund’s other service providers, market makers, Authorized Participants or issuers of securities in which the Fund invests.

Roundhill COST WeeklyPay™ ETF | DEBT SECURITIES RISK  
Prospectus [Line Items]  
Risk [Text Block]

DEBT SECURITIES RISK. Investments in debt securities subject the holder to the credit risk of the issuer. Credit risk refers to the possibility that the issuer or other obligor of a security will not be able or willing to make payments of interest and principal when due. Generally, the value of debt securities will change inversely with changes in interest rates. To the extent that interest rates rise, certain underlying obligations may be paid off substantially slower than originally anticipated and the value of those securities may fall sharply. During periods of falling interest rates, the income received by the Fund may decline. If the principal on a debt security is prepaid before expected, the prepayments of principal may have to be reinvested in obligations paying interest at lower rates. Debt securities generally do not trade on a securities exchange making them generally less liquid and more difficult to value than common stock.

Roundhill COST WeeklyPay™ ETF | DERIVATIVES RISK  
Prospectus [Line Items]  
Risk [Text Block]

DERIVATIVES RISK. The use of derivative instruments involves risks different from, or possibly greater than, the risks associated with investing directly in securities and other traditional investments. These risks include: (i) the risk that the counterparty to a derivative transaction may not fulfill its contractual obligations; (ii) risk of mispricing or improper valuation; and (iii) the risk that changes in the value of the derivative may not correlate perfectly with the underlying asset. Derivative prices are highly volatile and may fluctuate substantially during a short period of time. Such prices are influenced by numerous factors that affect the markets, including, but not limited to: changing supply and demand relationships; government programs and policies; national and international political and economic events, changes in interest rates, inflation and deflation and changes in supply and demand relationships. Trading derivative instruments involves risks different from, or possibly greater than, the risks associated with investing directly in securities. Derivative contracts ordinarily have leverage inherent in their terms. The use of leverage may cause the Fund to liquidate portfolio positions when it would not be advantageous to do so in order to satisfy its obligations or to meet regulatory or contractual requirements for derivatives. The use of derivatives can magnify potential for gain or loss and, therefore, amplify the effects of market volatility on share price.

Roundhill COST WeeklyPay™ ETF | DISTRIBUTION TAX RISK  
Prospectus [Line Items]  
Risk [Text Block]

DISTRIBUTION TAX RISK. The Fund currently expects to make distributions on a weekly basis. Such frequent distributions may expose investors to increased tax liabilities. However, these distributions may exceed the Fund’s income and gains for the Fund’s taxable year. Distributions in excess of the Fund’s current and accumulated earnings and profits will be treated as a return of capital. A return of capital distribution generally will not be taxable but will reduce the shareholder’s cost basis and will result in a higher capital gain or lower capital loss when those Fund Shares on which the distribution was received are sold. Once a Fund shareholder’s cost basis is reduced to zero, further distributions will be treated as capital gain if the Fund shareholder holds Fund Shares as capital assets. Additionally, any capital returned through distributions will be distributed after payment of Fund fees and expenses. Because a portion of the Fund’s distributions may consist of return of capital, the Fund may not be an appropriate investment for investors who do not want their principal investment in the Fund to decrease over time or who do not wish to receive return of capital in a given period. In the event that a shareholder purchases Fund Shares shortly before a distribution by the Fund, the entire distribution may be taxable to the shareholder even though a portion of the distribution effectively represents a return of the purchase price.

Roundhill COST WeeklyPay™ ETF | ETF RISK  
Prospectus [Line Items]  
Risk [Text Block]

ETF RISK. The Fund may invest in ETFs. The value of an ETF held by the Fund will fluctuate over time based on fluctuations in the values of the assets held by the ETF, which may be affected by changes in general economic conditions, expectations for future growth and profits, interest rates and the supply and demand for those assets. When the Fund invests in an ETF, it will bear a proportionate share of the ETF’s expenses. Brokerage, tax and other expenses may negatively impact the performance of the ETF and, in turn, the value of the Fund Shares. An ETF that tracks an index may not exactly match the performance of the index due to cash drag, differences between the portfolio of the ETF and the components of the index, expenses and other factors.

Roundhill COST WeeklyPay™ ETF | INFLATION RISK  
Prospectus [Line Items]  
Risk [Text Block]

INFLATION RISK. Inflation risk is the risk that the value of assets or income from investments will be less in the future as inflation decreases the value of money. As inflation increases, the present value of the Fund’s assets and distributions may decline. This risk is more prevalent with respect to fixed income securities held by the Fund.

Roundhill COST WeeklyPay™ ETF | Interest Rate Risk [Member]  
Prospectus [Line Items]  
Risk [Text Block]

INTEREST RATE RISK. Interest rate risk is the risk that the value of the debt securities in the Fund’s portfolio will decline because of rising market interest rates. Interest rate risk is generally lower for shorter term debt securities and higher for longer-term debt securities. Duration is a reasonably accurate measure of a debt security’s price sensitivity to changes in interest rates and a common measure of interest rate risk. Duration measures a debt security’s expected life on a present value basis, taking into account the debt security’s yield, interest payments and final maturity. In general, duration represents the expected percentage change in the value of a security for an immediate 1% change in interest rates. For example, the price of a debt security with a three-year duration would be expected to drop by approximately 3% in response to a 1% increase in interest rates. Therefore, prices of debt securities with shorter durations tend to be less sensitive to interest rate changes than debt securities with longer durations. As the value of a debt security changes over time, so will its duration.

Roundhill COST WeeklyPay™ ETF | LEGISLATION AND LITIGATION RISK  
Prospectus [Line Items]  
Risk [Text Block]

LEGISLATION AND LITIGATION RISK. Legislation or litigation that affects the value of assets or securities held by the Fund may reduce the value of the Fund. From time to time, various legislative initiatives are proposed that may have a negative impact on certain assets or securities in which the Fund invests. In addition, litigation regarding any of the assets or securities owned by the Fund may negatively impact the value of the Shares. Such legislation or litigation may cause the Fund to lose value or may result in higher portfolio turnover if the Adviser determines to sell such a holding.

Roundhill COST WeeklyPay™ ETF | LEVERAGE RISK  
Prospectus [Line Items]  
Risk [Text Block]

LEVERAGE RISK. The Fund obtains investment exposure in excess of its net assets by utilizing leverage and may lose more money in market conditions that are adverse to its investment objectives than a fund that does not utilize leverage. An investment in the Fund is exposed to the risk that a decline in the weekly performance of shares of COST will be magnified. This means that an investment in the Fund will be reduced by an amount equal to 1.2% for every 1% weekly decline in the market value of the COST shares, not including the costs of financing leverage and other operating expenses, which would further reduce its value. The Fund could theoretically lose an amount greater than its net assets in the event the market value of COST shares decline more than 83.33% over a calendar week. Leverage will also have the effect of magnifying any differences in the Fund’s correlation with COST shares.

Roundhill COST WeeklyPay™ ETF | MONEY MARKET INSTRUMENTS RISK  
Prospectus [Line Items]  
Risk [Text Block]

MONEY MARKET INSTRUMENTS RISK. The value of money market instruments may be affected by changing interest rates and by changes in the credit ratings of the investments. If a significant amount of the Fund’s assets are invested in money market instruments, it will be more difficult for the Fund to achieve its investment objectives. An investment in a money market fund is not insured or guaranteed by the FDIC or any other government agency. It is possible to lose money by investing in a money market fund.

Roundhill COST WeeklyPay™ ETF | OPERATIONAL RISK  
Prospectus [Line Items]  
Risk [Text Block]

OPERATIONAL RISK. The Fund is subject to risks arising from various operational factors, including, but not limited to, human error, processing and communication errors, errors of the Fund’s service providers, counterparties or other third-parties, failed or inadequate processes and technology or systems failures. The Fund relies on third-parties for a range of services, including custody. Any delay or failure relating to engaging or maintaining such service providers may affect the Fund’s ability to meet its investment objectives. Although the Fund and the Adviser seek to reduce these operational risks through controls and procedures, there is no way to completely protect against such risks.

Roundhill COST WeeklyPay™ ETF | SPECIAL TAX RISK  
Prospectus [Line Items]  
Risk [Text Block]

SPECIAL TAX RISK. The Fund intends to qualify annually and to elect to be treated as a regulated investment company under the Internal Revenue Code of 1986, as amended (the “Code”). To qualify for the favorable U.S. federal income tax treatment generally accorded to regulated investment companies, the Fund must, among other things, (i) derive in each taxable year at least 90% of its gross income from dividends, interest, payments with respect to securities loans and gains from the sale or other disposition of stock, securities or foreign currencies or other income derived with respect to its business of investing in such stock, securities or currencies, or net income derived from interests in certain publicly traded partnerships; (ii) diversify its holdings so that, at the end of each quarter of the taxable year, (a) at least 50% of the market value of the Fund’s assets is represented by cash and cash items (including receivables), U.S. government securities, the securities of other regulated investment companies and other securities, with such other securities of any one issuer generally limited for the purposes of this calculation to an amount not greater than 5% of the value of the Fund’s total assets and not greater than 10% of the outstanding voting securities of such issuer, and (b) not more than 25% of the value of its total assets is invested in the securities (other than U.S. government securities or the securities of other regulated investment companies) of any one issuer, or two or more issuers which the Fund controls which are engaged in the same, similar or related trades or businesses, or the securities of one or more of certain publicly traded partnerships; and (iii) distribute at least 90% of its investment company taxable income (which includes, among other items, dividends, interest and net short-term capital gains in excess of net long-term capital losses) and at least 90% of its net tax-exempt interest income each taxable year. There are certain exceptions for failure to qualify if the failure is for reasonable cause or is de minimis, and certain corrective action is taken and certain tax payments are made by the Fund.

 

The authority with regard to swaps entered into by regulated investment companies is unclear both as to the qualification under the income test and the identification of the issuer under the diversification test. The Fund intends to take the position that because the swaps held by the Fund reference securities that the income on the swaps are “other income” from the Fund’s business of investing in stocks and securities. In addition, the Fund intends to manage its investments in the swaps so that neither the exposure to issuer of the referenced security nor the exposure to any one counterparty of the swaps will exceed 25% of the gross value of the Fund’s portfolio at the end of any quarter.

 

If the Fund were to fail to meet the qualifying income test or asset diversification test and fail to qualify as a RIC, it would be taxed in the same manner as an ordinary corporation, and distributions to its shareholders would not be deductible by the Fund in computing its taxable income, which would adversely affect the Fund’s performance.

Roundhill COST WeeklyPay™ ETF | STRUCTURAL ETF RISKS  
Prospectus [Line Items]  
Risk [Text Block]

STRUCTURAL ETF RISKS. The Fund is an ETF. Accordingly, it is subject to certain risks associated with its unique structure.

 

Market Participants Risk. Only an Authorized Participant may engage in creation or redemption transactions directly with the Fund, and none of those Authorized Participants is obligated to engage in creation and/or redemption transactions. The Fund has a limited number of institutions that may act as Authorized Participants on an agency basis (i.e., on behalf of other market participants). To the extent that Authorized Participants exit the business or are unable to proceed with creation or redemption orders with respect to the Fund and no other Authorized Participant is able to step forward to create or redeem, Fund Shares may be more likely to trade at a premium or discount to NAV and possibly face trading halts or delisting. The Fund may also rely on a small number of third-party market makers to provide a market for the purchase and sale of Fund Shares but such market makers are under no obligation to do so. Decisions by Authorized Participants or market makers to reduce their role or step away from these activities in times of market stress could inhibit the effectiveness of the arbitrage process in maintaining the relationship between the underlying values of the Fund’s portfolio securities and the Fund’s market price. Any trading halt or other problem relating to the trading activity of these market makers or any issues disrupting the Authorized Participants’ ability to proceed with creation and/or redemption orders could result in a dramatic change in the spread between the Fund’s net asset value and the price at which Fund Shares are trading on the Exchange, which could result in a decrease in value of Fund Shares. This reduced effectiveness could result in Fund Shares trading at a premium or discount to net asset value and also in greater than normal intraday bid-ask spreads Fund Shares.

 

Cash Transactions Risk. The Fund currently expects to effect a significant portion of its creations and redemptions for cash, rather than in-kind securities. Paying redemption proceeds in cash rather than through in-kind delivery of portfolio securities may require the Fund to dispose of or sell portfolio securities or other assets at an inopportune time to obtain the cash needed to meet redemption orders. This may cause the Fund to sell a security and recognize a capital gain or loss that might not have been incurred if it had made a redemption in-kind. As a result, the Fund may pay out higher or lower annual capital gains distributions than ETFs that redeem in-kind. The use of cash creations and redemptions may also cause the Fund’s Shares to trade in the market at greater bid-ask spreads or greater premiums or discounts to the Fund’s NAV. Furthermore, the Fund may not be able to execute cash transactions for creation and redemption purposes at the same price used to determine the Fund’s NAV. To the extent that the maximum additional charge for creation or redemption transactions is insufficient to cover the execution shortfall, the Fund’s performance could be negatively impacted.

 

Costs of Buying and Selling Fund Shares. Due to the costs of buying or selling Fund Shares, including brokerage commissions imposed by brokers and bid/ask spreads, frequent trading of Fund Shares may significantly reduce investment results and an investment in Fund Shares may not be advisable for investors who anticipate regularly making small investments.

 

Premium/Discount Risk. As with all ETFs, Fund Shares may be bought and sold in the secondary market at market prices. The trading prices of Fund Shares in the secondary market may differ from the Fund’s daily net asset value per share and there may be times when the market price of the shares is more than the net asset value per share (premium) or less than the net asset value per share (discount). If a shareholder purchases Fund Shares at a time when the market price is at a premium to the net asset value or sells Fund Shares at a time when the market price is at a discount to the net asset value, the shareholder may pay more for, or receive less than, the underlying value of the Fund Shares, respectively. This risk is heightened in times of market volatility or periods of steep market declines.

 

Trading Risks. Although Fund Shares are listed for trading on the Exchange and may be traded on U.S. exchanges other than the Exchange, there can be no assurance that Fund Shares will trade with any volume, or at all, on any stock exchange. In stressed market conditions, the liquidity of Fund Shares may begin to mirror the liquidity of the Fund’s underlying portfolio holdings, which can be significantly less liquid than Fund Shares. Trading in Fund Shares on the Exchange may be halted due to market conditions or for reasons that, in the view of the Exchange, make trading in Fund Shares inadvisable. In addition, trading in Fund Shares on the Exchange is subject to trading halts caused by extraordinary market volatility pursuant to the Exchange’s “circuit breaker” rules. There can be no assurance that the requirements of the Exchange necessary to maintain the listing of the Fund will continue to be met or will remain unchanged.

Roundhill COST WeeklyPay™ ETF | U.S. GOVERNMENT SECURITIES RISK  
Prospectus [Line Items]  
Risk [Text Block]

U.S. GOVERNMENT SECURITIES RISK. U.S. government securities are subject to interest rate risk but generally do not involve the credit risks associated with investments in other types of debt securities. As a result, the yields available from U.S. government securities are generally lower than the yields available from other debt securities. U.S. government securities are guaranteed only as to the timely payment of interest and the payment of principal when held to maturity.

Roundhill COST WeeklyPay™ ETF | VALUATION RISK  
Prospectus [Line Items]  
Risk [Text Block]

VALUATION RISK. The Fund may hold securities or other assets that may be valued on the basis of factors other than market quotations. This may occur because the asset or security does not trade on a centralized exchange, or in times of market turmoil or reduced liquidity. There are multiple methods that can be used to value a portfolio holding when market quotations are not readily available. The value established for any portfolio holding at a point in time might differ from what would be produced using a different methodology or if it had been priced using market quotations. Portfolio holdings that are valued using techniques other than market quotations, including “fair valued” assets or securities, may be subject to greater fluctuation in their valuations from one day to the next than if market quotations were used. In addition, there is no assurance that the Fund could sell or close out a portfolio position for the value established for it at any time, and it is possible that the Fund would incur a loss because a portfolio position is sold or closed out at a discount to the valuation established by the Fund at that time. The Fund’s ability to value investments may be impacted by technological issues or errors by pricing services or other third-party service providers.

Roundhill COST WeeklyPay™ ETF | EQUITY SECURITIES RISK  
Prospectus [Line Items]  
Risk [Text Block]

EQUITY SECURITIES RISK. Equity securities are subject to changes in value, and their values may be more volatile than those of other asset classes. Equity securities prices fluctuate for several reasons, including changes in investors’ perceptions of the financial condition of an issuer or the general condition of the relevant equity market, such as market volatility, or when political or economic events affecting an issuer occur. Common stock prices may be particularly sensitive to rising interest rates, as the cost of capital rises and borrowing costs increase. Common stocks generally subject their holders to more risks than preferred stocks and debt securities because common stockholders’ claims are subordinated to those of holders of preferred stocks and debt securities upon the bankruptcy of the issuer.

Roundhill COST WeeklyPay™ ETF | SWAP AGREEMENTS RISK  
Prospectus [Line Items]  
Risk [Text Block]

SWAP AGREEMENTS RISK. The Fund will utilize swap agreements to derive its exposure to shares of COST. Swap agreements may involve greater risks than direct investment in securities as they may be leveraged and are subject to credit risk, counterparty risk and valuation risk. A swap agreement could result in losses if the underlying reference or asset does not perform as anticipated. In addition, many swaps trade over-the-counter and may be considered illiquid. It may not be possible for the Fund to liquidate a swap position at an advantageous time or price, which may result in significant losses.

Roundhill COST WeeklyPay™ ETF | REGULATED INVESTMENT COMPANY TAX RISKS  
Prospectus [Line Items]  
Risk [Text Block]

REGULATED INVESTMENT COMPANY TAX RISKS. The Fund intends to qualify annually and to elect to be treated as a regulated investment company under the Internal Revenue Code of 1986, as amended (the “Code”). To qualify for the favorable U.S. federal income tax treatment generally accorded to regulated investment companies, the Fund must, among other things, (i) derive in each taxable year at least 90% of its gross income from dividends, interest, payments with respect to securities loans and gains from the sale or other disposition of stock, securities or foreign currencies or other income derived with respect to its business of investing in such stock, securities or currencies, or net income derived from interests in certain publicly traded partnerships; (ii) diversify its holdings so that, at the end of each quarter of the taxable year, (a) at least 50% of the market value of the Fund’s assets is represented by cash and cash items (including receivables), U.S. government securities, the securities of other regulated investment companies and other securities, with such other securities of any one issuer generally limited for the purposes of this calculation to an amount not greater than 5% of the value of the Fund’s total assets and not greater than 10% of the outstanding voting securities of such issuer, and (b) not more than 25% of the value of its total assets is invested in the securities (other than U.S. government securities or the securities of other regulated investment companies) of any one issuer, or two or more issuers which the Fund controls which are engaged in the same, similar or related trades or businesses, or the securities of one or more of certain publicly traded partnerships; and (iii) distribute at least 90% of its investment company taxable income (which includes, among other items, dividends, interest and net short-term capital gains in excess of net long-term capital losses) and at least 90% of its net tax-exempt interest income each taxable year. There are certain exceptions for failure to qualify if the failure is for reasonable cause or is de minimis, and certain corrective action is taken and certain tax payments are made by the Fund.

 

If the Fund were to fail to meet the qualifying income test or asset diversification test and fail to qualify as a RIC, it would be taxed in the same manner as an ordinary corporation, and distributions to its shareholders would not be deductible by the Fund in computing its taxable income, which would adversely affect the Fund’s performance.

Roundhill COST WeeklyPay™ ETF | LARGE SHAREHOLDER RISK  
Prospectus [Line Items]  
Risk [Text Block]

LARGE SHAREHOLDER RISK. Certain shareholders, including affiliated funds advised by the Adviser, may from time to time own a significant portion of the Fund’s shares. In addition, a third-party investor, the Adviser or an affiliate of the Adviser (“Affiliate”), an authorized participant, a market maker, or another entity may invest in the Fund and hold its investment for a limited period solely to facilitate the commencement of the Fund or to help the Fund achieve a specified size or scale. There can be no assurance that any large shareholder will not redeem its investment, that the size of the Fund will be maintained at such levels, or that the Fund will continue to meet applicable listing requirements. Redemptions by large shareholders could have a significant negative impact on the Fund. In addition, transactions by large shareholders may account for a large percentage of the trading volume on the Fund’s listing exchange and may, therefore, have a material upward or downward effect on the market price of the shares.

 

To the extent that a significant percentage of the Fund’s shares are owned or controlled by a small number of account shareholders (or a single account shareholder), including funds or accounts over which the Adviser or an Affiliate has investment discretion, the Fund is subject to the risk that those shareholders may purchase or redeem Fund shares in significant amounts rapidly or unexpectedly, including as a result of an asset allocation decision made by the Adviser or an Affiliate. This may adversely affect the Fund’s performance if the Adviser is forced to sell portfolio securities or invest cash when it would not otherwise choose to do so. Redemptions of a large number of shares may affect the liquidity of the Fund’s portfolio, increase the Fund’s transaction costs, and accelerate the realization of taxable income and/or gains. In addition, a large redemption could result in the Fund’s current expenses being allocated over a smaller asset base, leading to an increase in the Fund’s gross expense ratio. Large purchases of the Fund’s shares may also adversely affect the Fund’s performance to the extent that the Fund is delayed in investing new cash or otherwise maintains a larger cash position than it ordinarily would, particularly if the Fund accepts cash for an order for the purchase of creation units of the Fund’s shares.

Roundhill COST WeeklyPay™ ETF | COST INVESTING RISKS  
Prospectus [Line Items]  
Risk [Text Block]

COST INVESTING RISKS. The Fund will have significant exposure to COST through its investments in swap agreements that utilize COST as the reference asset. Accordingly, the Fund will subject to the risks of COST, set forth below.

 

COST ISSUER-SPECIFIC RISKS. Issuer-specific attributes may cause an investment held by the Fund to be more volatile than the market generally. The value of an individual security or particular type of security may be more volatile than the market as a whole and may perform differently from the value of the market as a whole. The retail sector is highly competitive, with COST facing challenges from other warehouse clubs, traditional brick-and-mortar retailers and other large e-commerce companies. While COST has a strong physical presence, it has been slower to adapt to the growing e-commerce trend compared to some competitors. This lag could affect its ability to capture online market share. A significant portion of COST’s revenue comes from membership fees. Any decline in membership renewal rates or new sign-ups could adversely affect financial performance. COST’s performance is tied to consumer spending, which can be influenced by economic downturns, inflation, or changes in disposable income levels. Economic challenges could lead to reduced consumer spending, impacting sales.

 

CONSUMER STAPLES COMPANIES RISK. Consumer staples companies provide products directly to the consumer that are typically considered non-discretionary items based on consumer purchasing habits. Such products include food, beverages, household items and tobacco. Companies providing these products may be affected by the regulation of various product components and production methods, new laws, regulations or litigation, marketing campaigns, competitive pricing, enumerated factors, consumer confidence, materials costs and other factors affecting consumer demand. Changes in the worldwide economy, demographics, consumer preferences, consumer spending, exploration and production spending may adversely affect these companies, as well as natural and man-made disasters, political, social or labor unrest, world events and economic conditions. Historically, the demand for consumer staples goods has remained fairly constant regardless of the state of the economy. With some products, such as food, alcohol and tobacco, demand sometimes increases during economic downturns. However, price competition among suppliers may be very challenging, which can drive prices lower and impact returns.

 

INDIRECT INVESTMENT RISK. Costco Wholesale Corporation is not affiliated with the Trust, the Fund, the Adviser, the Sub-Adviser or any affiliates thereof and is not involved with this offering in any way, and has no obligation to consider the Fund in taking any corporate actions that might affect the value of the Fund. The Trust, the Fund, the Adviser, the Sub-Adviser or any affiliate are not responsible for the performance of COST and make no representation as to the performance of COST. Investing in the Fund is not equivalent to investing in COST. Fund shareholders will not have voting rights or rights to receive dividends or other distributions or any other rights with respect to COST.

 

LARGE CAPITALIZATION COMPANIES RISK. Large capitalization companies may be less able than smaller capitalization companies to adapt to changing market conditions. Large capitalization companies may be more mature and subject to more limited growth potential compared with smaller capitalization companies. During different market cycles, the performance of large capitalization companies has trailed the overall performance of the broader securities markets.

 

RETAIL COMPANIES RISK. Companies involved in retail may be affected by the performance of the domestic and international economy, interest rates, rates of inflation, exchange rates, competition, consumer confidence and reputational damage. The success of companies involved in retail depends heavily on disposable household income and consumer spending, and changes in demographics and consumer preferences can affect the success of retail companies. Certain retail companies have historically been subject to significant seasonal and quarterly variations. The success of retail companies may be strongly affected by fads, marketing campaigns and other factors affecting supply and demand and a retail company’s success can be tied to its ability to anticipate changing consumer tastes. These companies may be subject to severe competition, which may have an adverse impact on their profitability. Certain business segments of retail companies are highly cyclical, which may cause the operating results of such retail companies to vary significantly. Retail companies may be dependent on outside financing, which may be difficult to obtain. Many of these companies are dependent on third party suppliers and distribution systems and purchase merchandise both directly from brand owners and indirectly from retailers and third-party suppliers. Such companies may also be dependent upon suppliers for the products used for their own brand name merchandise. Reliance on third party suppliers subjects retail companies to risks of delivery delays, price increases and receipt of nonconforming or poor quality merchandise. Retail companies may be unable to protect their intellectual property rights and may be liable for infringing the intellectual property rights of others. Changes in labor laws and other labor issues, such as increased labor costs, could adversely affect the financial performance of retail companies. If retail companies do not maintain the security of customer-related information, they could damage their reputations with customers, incur substantial costs and become subject to litigation, all of which could adversely affect the financial performance of such companies. The international operations of certain retail companies expose them to risks associated with instability and changes in economic and political conditions, foreign currency fluctuations, changes in foreign regulations, tariffs and trade disputes and other risks inherent to international business. Some of the companies in the Retail Index are engaged in other lines of business unrelated to retail, and they may experience problems with these lines of business which could adversely affect their operating results. The operating results of these companies may fluctuate as a result of these additional risks and events in the other lines of business. In addition, a company’s ability to engage in new activities may expose it to business risks with which it has less experience than it has with the business risks associated with its traditional businesses. Despite a company’s possible success in traditional retail activities, the other lines of business in which these companies are engaged may have an adverse effect on a company’s business or financial condition.

 

UNITED STATES RISK. Certain changes in the U.S. economy, such as when the U.S. economy weakens or when its financial markets decline, may have an adverse effect on the securities to which the Fund has exposure.

NON-DIVERSIFICATION RISK. As a “non-diversified” fund, the Fund may hold a smaller number of portfolio securities than many other funds. To the extent the Fund invests in a relatively small number of issuers, a decline in the market value of a particular security held by the Fund may affect its value more than if it invested in a larger number of issuers. The value of the Fund Shares may be more volatile than the values of shares of more diversified funds.

Roundhill CRWD WeeklyPay™ ETF | MARKET RISK  
Prospectus [Line Items]  
Risk [Text Block]

MARKET RISK. Market risk is the risk that a particular investment, or Fund Shares in general, may fall in value. Securities are subject to market fluctuations caused by real or perceived adverse economic, political, and regulatory factors or market developments, changes in interest rates, disruptions to trade, impositions of tariffs and perceived trends in securities prices. Fund Shares could decline in value or underperform other investments. In addition, local, regional or global events such as war, acts of terrorism, market manipulation, government defaults, government shutdowns, regulatory actions, political changes, diplomatic developments, the imposition of sanctions and other similar measures, spread of infectious diseases or other public health issues, recessions, natural disasters, or other events could have a significant negative impact on the Fund and its investments. Any of such circumstances could have a materially negative impact on the value of Fund Shares, the liquidity of an investment, and may result in increased market volatility. During any such events, Fund Shares may trade at increased premiums or discounts to their net asset value, the bid/ask spread on Fund Shares may widen and the returns on investment may fluctuate.

Roundhill CRWD WeeklyPay™ ETF | LIQUIDITY RISK  
Prospectus [Line Items]  
Risk [Text Block]

LIQUIDITY RISK. The market for swap agreements that reference CRWD shares may be subject to periods of illiquidity. During such times it may be difficult or impossible to buy or sell a position at the desired price. Market disruptions or volatility can also make it difficult to find a counterparty willing to transact at a reasonable price and sufficient size. Illiquid markets may cause losses, which could be significant. The large size of the positions which the Fund may acquire increases the risk of illiquidity, may make its positions more difficult to liquidate, and may increase the losses incurred while trying to do so. Such large positions also may impact the price of swap agreements on CRWD shares.

Roundhill CRWD WeeklyPay™ ETF | ACTIVE MANAGEMENT RISK

ACTIVE MANAGEMENT RISK. The Fund is actively-managed and its performance reflects investment decisions that the Adviser and/or Sub-Adviser makes for the Fund. Such judgments about the Fund’s investments may prove to be incorrect. If the investments selected and the strategies employed by the Fund fail to produce the intended results, the Fund could underperform as compared to other funds with similar investment objectives and/or strategies, or could have negative returns.

Roundhill CRWD WeeklyPay™ ETF | ACTIVE MARKET RISK

ACTIVE MARKET RISK. Although Fund Shares are listed for trading on the Exchange, there can be no assurance that an active trading market for Fund Shares will develop or be maintained. Fund Shares trade on the Exchange at market prices that may be below, at or above the Fund’s net asset value. Securities, including Fund Shares, are subject to market fluctuations and liquidity constraints that may be caused by such factors as economic, political, or regulatory developments, changes in interest rates, and/or perceived trends in securities prices. Fund Shares could decline in value or underperform other investments.

CONCENTRATION RISK. The Fund is susceptible to an increased risk of loss, including losses due to adverse events that affect the Fund’s investments more than the market as a whole, to the extent that the Fund’s investments are concentrated in investments that provide exposure to CRWD and the industry to which it is assigned.

COUNTERPARTY RISK. Fund transactions involving a counterparty are subject to the risk that the counterparty will not fulfill its obligation to the Fund. Counterparty risk may arise because of the counterparty’s financial condition (i.e., financial difficulties, bankruptcy, or insolvency), market activities and developments, or other reasons, whether foreseen or not. A counterparty’s inability to fulfill its obligation may result in significant financial loss to the Fund. The Fund may be unable to recover its investment from the counterparty or may obtain a limited recovery, and/or recovery may be delayed.

CREDIT RISK. An issuer or other obligated party of a debt security may be unable or unwilling to make dividend, interest and/or principal payments when due. In addition, the value of a debt security may decline because of concerns about the issuer’s ability or unwillingness to make such payments.

Roundhill CRWD WeeklyPay™ ETF | CURRENT MARKET CONDITIONS RISK  
Prospectus [Line Items]  
Risk [Text Block]

CURRENT MARKET CONDITIONS RISK. Current market conditions risk is the risk that a particular investment, or Fund Shares in general, may fall in value due to current market conditions. As a means to fight inflation, which remains at elevated levels, the Federal Reserve and certain foreign central banks have raised interest rates; however, the Federal Reserve has recently lowered interest rates and may continue to do so. U.S. regulators have proposed several changes to market and issuer regulations which would directly impact the Fund, and any regulatory changes could adversely impact the Fund’s ability to achieve its investment strategies or make certain investments. Recent and potential future bank failures could result in disruption to the broader banking industry or markets generally and reduce confidence in financial institutions and the economy as a whole, which may also heighten market volatility and reduce liquidity. Additionally, challenges in commercial real estate markets, including rising interest rates, declining valuations and increasing vacancies, could have a broader impact on financial markets. The ongoing adversarial political climate in the United States, as well as political and diplomatic events both domestic and abroad, have and may continue to have an adverse impact the U.S. regulatory landscape, markets and investor behavior, which could have a negative impact on the Fund’s investments and operations. The change in administration resulting from the 2024 United States national elections could result in significant impacts to international trade relations, tax and immigration policies, and other aspects of the national and international political and financial landscape, which could affect, among other things, inflation and the securities markets generally. Other unexpected political, regulatory and diplomatic events within the U.S. and abroad may affect investor and consumer confidence and may adversely impact financial markets and the broader economy. For example, ongoing armed conflicts between Russia and Ukraine in Europe and among Israel, Iran, Hamas and other militant groups in the Middle East, have caused and could continue to cause significant market disruptions and volatility within the markets in Russia, Europe, the Middle East and the United States. The hostilities and sanctions resulting from those hostilities have and could continue to have a significant impact on certain Fund investments as well as Fund performance and liquidity. The economies of the United States and its trading partners, as well as the financial markets generally, may be adversely impacted by trade disputes, including the imposition of tariffs, and other matters. For example, the United States has imposed trade barriers and restrictions on China. In addition, the Chinese government is engaged in a longstanding dispute with Taiwan, continually threatening an invasion. If the political climate between the United States and China does not improve or continues to deteriorate, if China were to attempt invading Taiwan, or if other geopolitical conflicts develop or worsen, economies, markets and individual securities may be adversely affected, and the value of the Fund’s assets may go down. A public health crisis and the ensuing policies enacted by governments and central banks may cause significant volatility and uncertainty in global financial markets, negatively impacting global growth prospects. As the COVID-19 global pandemic illustrated, such events may affect certain geographic regions, countries, sectors and industries more significantly than others. Advancements in technology may also adversely impact markets and the overall performance of the Fund. For instance, the economy may be significantly impacted by the advanced development and increased regulation of artificial intelligence. Additionally, cyber security breaches of both government and non-government entities could have negative impacts on infrastructure and the ability of such entities, including the Fund, to operate properly. These events, and any other future events, may adversely affect the prices and liquidity of the Fund’s portfolio investments and could result in disruptions in the trading markets.

Roundhill CRWD WeeklyPay™ ETF | CYBERSECURITY RISK

CYBERSECURITY RISK. Failures or breaches of the electronic systems of the Fund, the Fund’s adviser, sub-adviser, distributor and other service providers, market makers, Authorized Participants or the issuers of securities in which the Fund invests have the ability to cause disruptions, negatively impact the Fund’s business operations and/or potentially result in financial losses to the Fund and its shareholders. While the Fund has established business continuity plans and risk management systems seeking to address system breaches or failures, there are inherent limitations in such plans and systems. Furthermore, the Fund cannot control the cybersecurity plans and systems of the Fund’s other service providers, market makers, Authorized Participants or issuers of securities in which the Fund invests.

Roundhill CRWD WeeklyPay™ ETF | DEBT SECURITIES RISK  
Prospectus [Line Items]  
Risk [Text Block]

DEBT SECURITIES RISK. Investments in debt securities subject the holder to the credit risk of the issuer. Credit risk refers to the possibility that the issuer or other obligor of a security will not be able or willing to make payments of interest and principal when due. Generally, the value of debt securities will change inversely with changes in interest rates. To the extent that interest rates rise, certain underlying obligations may be paid off substantially slower than originally anticipated and the value of those securities may fall sharply. During periods of falling interest rates, the income received by the Fund may decline. If the principal on a debt security is prepaid before expected, the prepayments of principal may have to be reinvested in obligations paying interest at lower rates. Debt securities generally do not trade on a securities exchange making them generally less liquid and more difficult to value than common stock.

Roundhill CRWD WeeklyPay™ ETF | DERIVATIVES RISK  
Prospectus [Line Items]  
Risk [Text Block]

DERIVATIVES RISK. The use of derivative instruments involves risks different from, or possibly greater than, the risks associated with investing directly in securities and other traditional investments. These risks include: (i) the risk that the counterparty to a derivative transaction may not fulfill its contractual obligations; (ii) risk of mispricing or improper valuation; and (iii) the risk that changes in the value of the derivative may not correlate perfectly with the underlying asset. Derivative prices are highly volatile and may fluctuate substantially during a short period of time. Such prices are influenced by numerous factors that affect the markets, including, but not limited to: changing supply and demand relationships; government programs and policies; national and international political and economic events, changes in interest rates, inflation and deflation and changes in supply and demand relationships. Trading derivative instruments involves risks different from, or possibly greater than, the risks associated with investing directly in securities. Derivative contracts ordinarily have leverage inherent in their terms. The use of leverage may cause the Fund to liquidate portfolio positions when it would not be advantageous to do so in order to satisfy its obligations or to meet regulatory or contractual requirements for derivatives. The use of derivatives can magnify potential for gain or loss and, therefore, amplify the effects of market volatility on share price.

Roundhill CRWD WeeklyPay™ ETF | DISTRIBUTION TAX RISK  
Prospectus [Line Items]  
Risk [Text Block]

DISTRIBUTION TAX RISK. The Fund currently expects to make distributions on a weekly basis. Such frequent distributions may expose investors to increased tax liabilities. However, these distributions may exceed the Fund’s income and gains for the Fund’s taxable year. Distributions in excess of the Fund’s current and accumulated earnings and profits will be treated as a return of capital. A return of capital distribution generally will not be taxable but will reduce the shareholder’s cost basis and will result in a higher capital gain or lower capital loss when those Fund Shares on which the distribution was received are sold. Once a Fund shareholder’s cost basis is reduced to zero, further distributions will be treated as capital gain if the Fund shareholder holds Fund Shares as capital assets. Additionally, any capital returned through distributions will be distributed after payment of Fund fees and expenses. Because a portion of the Fund’s distributions may consist of return of capital, the Fund may not be an appropriate investment for investors who do not want their principal investment in the Fund to decrease over time or who do not wish to receive return of capital in a given period. In the event that a shareholder purchases Fund Shares shortly before a distribution by the Fund, the entire distribution may be taxable to the shareholder even though a portion of the distribution effectively represents a return of the purchase price.

Roundhill CRWD WeeklyPay™ ETF | ETF RISK  
Prospectus [Line Items]  
Risk [Text Block]

ETF RISK. The Fund may invest in ETFs. The value of an ETF held by the Fund will fluctuate over time based on fluctuations in the values of the assets held by the ETF, which may be affected by changes in general economic conditions, expectations for future growth and profits, interest rates and the supply and demand for those assets. When the Fund invests in an ETF, it will bear a proportionate share of the ETF’s expenses. Brokerage, tax and other expenses may negatively impact the performance of the ETF and, in turn, the value of the Fund Shares. An ETF that tracks an index may not exactly match the performance of the index due to cash drag, differences between the portfolio of the ETF and the components of the index, expenses and other factors.

Roundhill CRWD WeeklyPay™ ETF | INFLATION RISK

Risk [Text Block]

INFLATION RISK. Inflation risk is the risk that the value of assets or income from investments will be less in the future as inflation decreases the value of money. As inflation increases, the present value of the Fund’s assets and distributions may decline. This risk is more prevalent with respect to fixed income securities held by the Fund.

Roundhill CRWD WeeklyPay™ ETF | Interest Rate Risk [Member]  
Prospectus [Line Items]  
Risk [Text Block]

INTEREST RATE RISK. Interest rate risk is the risk that the value of the debt securities in the Fund’s portfolio will decline because of rising market interest rates. Interest rate risk is generally lower for shorter term debt securities and higher for longer-term debt securities. Duration is a reasonably accurate measure of a debt security’s price sensitivity to changes in interest rates and a common measure of interest rate risk. Duration measures a debt security’s expected life on a present value basis, taking into account the debt security’s yield, interest payments and final maturity. In general, duration represents the expected percentage change in the value of a security for an immediate 1% change in interest rates. For example, the price of a debt security with a three-year duration would be expected to drop by approximately 3% in response to a 1% increase in interest rates. Therefore, prices of debt securities with shorter durations tend to be less sensitive to interest rate changes than debt securities with longer durations. As the value of a debt security changes over time, so will its duration.

Roundhill CRWD WeeklyPay™ ETF | LEGISLATION AND LITIGATION RISK  
Prospectus [Line Items]  
Risk [Text Block]

LEGISLATION AND LITIGATION RISK. Legislation or litigation that affects the value of assets or securities held by the Fund may reduce the value of the Fund. From time to time, various legislative initiatives are proposed that may have a negative impact on certain assets or securities in which the Fund invests. In addition, litigation regarding any of the assets or securities owned by the Fund may negatively impact the value of the Shares. Such legislation or litigation may cause the Fund to lose value or may result in higher portfolio turnover if the Adviser determines to sell such a holding.

Roundhill CRWD WeeklyPay™ ETF | LEVERAGE RISK  
Prospectus [Line Items]  
Risk [Text Block]

LEVERAGE RISK. The Fund obtains investment exposure in excess of its net assets by utilizing leverage and may lose more money in market conditions that are adverse to its investment objectives than a fund that does not utilize leverage. An investment in the Fund is exposed to the risk that a decline in the weekly performance of shares of CRWD will be magnified. This means that an investment in the Fund will be reduced by an amount equal to 1.2% for every 1% weekly decline in the market value of the CRWD shares, not including the costs of financing leverage and other operating expenses, which would further reduce its value. The Fund could theoretically lose an amount greater than its net assets in the event the market value of CRWD shares decline more than 83.33% over a calendar week. Leverage will also have the effect of magnifying any differences in the Fund’s correlation with CRWD shares.

Roundhill CRWD WeeklyPay™ ETF | MONEY MARKET INSTRUMENTS RISK  
Prospectus [Line Items]  
Risk [Text Block]

MONEY MARKET INSTRUMENTS RISK. The value of money market instruments may be affected by changing interest rates and by changes in the credit ratings of the investments. If a significant amount of the Fund’s assets are invested in money market instruments, it will be more difficult for the Fund to achieve its investment objectives. An investment in a money market fund is not insured or guaranteed by the FDIC or any other government agency. It is possible to lose money by investing in a money market fund.

Roundhill CRWD WeeklyPay™ ETF | OPERATIONAL RISK  
Prospectus [Line Items]  
Risk [Text Block]

OPERATIONAL RISK. The Fund is subject to risks arising from various operational factors, including, but not limited to, human error, processing and communication errors, errors of the Fund’s service providers, counterparties or other third-parties, failed or inadequate processes and technology or systems failures. The Fund relies on third-parties for a range of services, including custody. Any delay or failure relating to engaging or maintaining such service providers may affect the Fund’s ability to meet its investment objectives. Although the Fund and the Adviser seek to reduce these operational risks through controls and procedures, there is no way to completely protect against such risks.

Roundhill CRWD WeeklyPay™ ETF | SPECIAL TAX RISK  
Prospectus [Line Items]  
Risk [Text Block]

SPECIAL TAX RISK. The Fund intends to qualify annually and to elect to be treated as a regulated investment company under the Internal Revenue Code of 1986, as amended (the “Code”). To qualify for the favorable U.S. federal income tax treatment generally accorded to regulated investment companies, the Fund must, among other things, (i) derive in each taxable year at least 90% of its gross income from dividends, interest, payments with respect to securities loans and gains from the sale or other disposition of stock, securities or foreign currencies or other income derived with respect to its business of investing in such stock, securities or currencies, or net income derived from interests in certain publicly traded partnerships; (ii) diversify its holdings so that, at the end of each quarter of the taxable year, (a) at least 50% of the market value of the Fund’s assets is represented by cash and cash items (including receivables), U.S. government securities, the securities of other regulated investment companies and other securities, with such other securities of any one issuer generally limited for the purposes of this calculation to an amount not greater than 5% of the value of the Fund’s total assets and not greater than 10% of the outstanding voting securities of such issuer, and (b) not more than 25% of the value of its total assets is invested in the securities (other than U.S. government securities or the securities of other regulated investment companies) of any one issuer, or two or more issuers which the Fund controls which are engaged in the same, similar or related trades or businesses, or the securities of one or more of certain publicly traded partnerships; and (iii) distribute at least 90% of its investment company taxable income (which includes, among other items, dividends, interest and net short-term capital gains in excess of net long-term capital losses) and at least 90% of its net tax-exempt interest income each taxable year. There are certain exceptions for failure to qualify if the failure is for reasonable cause or is de minimis, and certain corrective action is taken and certain tax payments are made by the Fund.

 

The authority with regard to swaps entered into by regulated investment companies is unclear both as to the qualification under the income test and the identification of the issuer under the diversification test. The Fund intends to take the position that because the swaps held by the Fund reference securities that the income on the swaps are “other income” from the Fund’s business of investing in stocks and securities. In addition, the Fund intends to manage its investments in the swaps so that neither the exposure to issuer of the referenced security nor the exposure to any one counterparty of the swaps will exceed 25% of the gross value of the Fund’s portfolio at the end of any quarter.

 

If the Fund were to fail to meet the qualifying income test or asset diversification test and fail to qualify as a RIC, it would be taxed in the same manner as an ordinary corporation, and distributions to its shareholders would not be deductible by the Fund in computing its taxable income, which would adversely affect the Fund’s performance.

Roundhill CRWD WeeklyPay™ ETF | STRUCTURAL ETF RISKS  
Prospectus [Line Items]  
Risk [Text Block]

STRUCTURAL ETF RISKS. The Fund is an ETF. Accordingly, it is subject to certain risks associated with its unique structure.

 

Market Participants Risk. Only an Authorized Participant may engage in creation or redemption transactions directly with the Fund, and none of those Authorized Participants is obligated to engage in creation and/or redemption transactions. The Fund has a limited number of institutions that may act as Authorized Participants on an agency basis (i.e., on behalf of other market participants). To the extent that Authorized Participants exit the business or are unable to proceed with creation or redemption orders with respect to the Fund and no other Authorized Participant is able to step forward to create or redeem, Fund Shares may be more likely to trade at a premium or discount to NAV and possibly face trading halts or delisting. The Fund may also rely on a small number of third-party market makers to provide a market for the purchase and sale of Fund Shares but such market makers are under no obligation to do so. Decisions by Authorized Participants or market makers to reduce their role or step away from these activities in times of market stress could inhibit the effectiveness of the arbitrage process in maintaining the relationship between the underlying values of the Fund’s portfolio securities and the Fund’s market price. Any trading halt or other problem relating to the trading activity of these market makers or any issues disrupting the Authorized Participants’ ability to proceed with creation and/or redemption orders could result in a dramatic change in the spread between the Fund’s net asset value and the price at which Fund Shares are trading on the Exchange, which could result in a decrease in value of Fund Shares. This reduced effectiveness could result in Fund Shares trading at a premium or discount to net asset value and also in greater than normal intraday bid-ask spreads Fund Shares.

 

Cash Transactions Risk. The Fund currently expects to effect a significant portion of its creations and redemptions for cash, rather than in-kind securities. Paying redemption proceeds in cash rather than through in-kind delivery of portfolio securities may require the Fund to dispose of or sell portfolio securities or other assets at an inopportune time to obtain the cash needed to meet redemption orders. This may cause the Fund to sell a security and recognize a capital gain or loss that might not have been incurred if it had made a redemption in-kind. As a result, the Fund may pay out higher or lower annual capital gains distributions than ETFs that redeem in-kind. The use of cash creations and redemptions may also cause the Fund’s Shares to trade in the market at greater bid-ask spreads or greater premiums or discounts to the Fund’s NAV. Furthermore, the Fund may not be able to execute cash transactions for creation and redemption purposes at the same price used to determine the Fund’s NAV. To the extent that the maximum additional charge for creation or redemption transactions is insufficient to cover the execution shortfall, the Fund’s performance could be negatively impacted.

 

Costs of Buying and Selling Fund Shares. Due to the costs of buying or selling Fund Shares, including brokerage commissions imposed by brokers and bid/ask spreads, frequent trading of Fund Shares may significantly reduce investment results and an investment in Fund Shares may not be advisable for investors who anticipate regularly making small investments.

 

Premium/Discount Risk. As with all ETFs, Fund Shares may be bought and sold in the secondary market at market prices. The trading prices of Fund Shares in the secondary market may differ from the Fund’s daily net asset value per share and there may be times when the market price of the shares is more than the net asset value per share (premium) or less than the net asset value per share (discount). If a shareholder purchases Fund Shares at a time when the market price is at a premium to the net asset value or sells Fund Shares at a time when the market price is at a discount to the net asset value, the shareholder may pay more for, or receive less than, the underlying value of the Fund Shares, respectively. This risk is heightened in times of market volatility or periods of steep market declines.

 

Trading Risks. Although Fund Shares are listed for trading on the Exchange and may be traded on U.S. exchanges other than the Exchange, there can be no assurance that Fund Shares will trade with any volume, or at all, on any stock exchange. In stressed market conditions, the liquidity of Fund Shares may begin to mirror the liquidity of the Fund’s underlying portfolio holdings, which can be significantly less liquid than Fund Shares. Trading in Fund Shares on the Exchange may be halted due to market conditions or for reasons that, in the view of the Exchange, make trading in Fund Shares inadvisable. In addition, trading in Fund Shares on the Exchange is subject to trading halts caused by extraordinary market volatility pursuant to the Exchange’s “circuit breaker” rules. There can be no assurance that the requirements of the Exchange necessary to maintain the listing of the Fund will continue to be met or will remain unchanged.

Roundhill CRWD WeeklyPay™ ETF | U.S. GOVERNMENT SECURITIES RISK  
Prospectus [Line Items]  
Risk [Text Block]

U.S. GOVERNMENT SECURITIES RISK. U.S. government securities are subject to interest rate risk but generally do not involve the credit risks associated with investments in other types of debt securities. As a result, the yields available from U.S. government securities are generally lower than the yields available from other debt securities. U.S. government securities are guaranteed only as to the timely payment of interest and the payment of principal when held to maturity.

Roundhill CRWD WeeklyPay™ ETF | VALUATION RISK  
Prospectus [Line Items]  
Risk [Text Block]

VALUATION RISK. The Fund may hold securities or other assets that may be valued on the basis of factors other than market quotations. This may occur because the asset or security does not trade on a centralized exchange, or in times of market turmoil or reduced liquidity. There are multiple methods that can be used to value a portfolio holding when market quotations are not readily available. The value established for any portfolio holding at a point in time might differ from what would be produced using a different methodology or if it had been priced using market quotations. Portfolio holdings that are valued using techniques other than market quotations, including “fair valued” assets or securities, may be subject to greater fluctuation in their valuations from one day to the next than if market quotations were used. In addition, there is no assurance that the Fund could sell or close out a portfolio position for the value established for it at any time, and it is possible that the Fund would incur a loss because a portfolio position is sold or closed out at a discount to the valuation established by the Fund at that time. The Fund’s ability to value investments may be impacted by technological issues or errors by pricing services or other third-party service providers.

Roundhill CRWD WeeklyPay™ ETF | EQUITY SECURITIES RISK  
Prospectus [Line Items]  
Risk [Text Block]

EQUITY SECURITIES RISK. Equity securities are subject to changes in value, and their values may be more volatile than those of other asset classes. Equity securities prices fluctuate for several reasons, including changes in investors’ perceptions of the financial condition of an issuer or the general condition of the relevant equity market, such as market volatility, or when political or economic events affecting an issuer occur. Common stock prices may be particularly sensitive to rising interest rates, as the cost of capital rises and borrowing costs increase. Common stocks generally subject their holders to more risks than preferred stocks and debt securities because common stockholders’ claims are subordinated to those of holders of preferred stocks and debt securities upon the bankruptcy of the issuer.

Roundhill CRWD WeeklyPay™ ETF | SWAP AGREEMENTS RISK  
Prospectus [Line Items]  
Risk [Text Block]

SWAP AGREEMENTS RISK. The Fund will utilize swap agreements to derive its exposure to shares of CRWD. Swap agreements may involve greater risks than direct investment in securities as they may be leveraged and are subject to credit risk, counterparty risk and valuation risk. A swap agreement could result in losses if the underlying reference or asset does not perform as anticipated. In addition, many swaps trade over-the-counter and may be considered illiquid. It may not be possible for the Fund to liquidate a swap position at an advantageous time or price, which may result in significant losses.

Roundhill CRWD WeeklyPay™ ETF | NEW FUND RISK

Prospectus [Line Items]  
Risk [Text Block]

REGULATED INVESTMENT COMPANY TAX RISKS. The Fund intends to qualify annually and to elect to be treated as a regulated investment company under the Internal Revenue Code of 1986, as amended (the “Code”). To qualify for the favorable U.S. federal income tax treatment generally accorded to regulated investment companies, the Fund must, among other things, (i) derive in each taxable year at least 90% of its gross income from dividends, interest, payments with respect to securities loans and gains from the sale or other disposition of stock, securities or foreign currencies or other income derived with respect to its business of investing in such stock, securities or currencies, or net income derived from interests in certain publicly traded partnerships; (ii) diversify its holdings so that, at the end of each quarter of the taxable year, (a) at least 50% of the market value of the Fund’s assets is represented by cash and cash items (including receivables), U.S. government securities, the securities of other regulated investment companies and other securities, with such other securities of any one issuer generally limited for the purposes of this calculation to an amount not greater than 5% of the value of the Fund’s total assets and not greater than 10% of the outstanding voting securities of such issuer, and (b) not more than 25% of the value of its total assets is invested in the securities (other than U.S. government securities or the securities of other regulated investment companies) of any one issuer, or two or more issuers which the Fund controls which are engaged in the same, similar or related trades or businesses, or the securities of one or more of certain publicly traded partnerships; and (iii) distribute at least 90% of its investment company taxable income (which includes, among other items, dividends, interest and net short-term capital gains in excess of net long-term capital losses) and at least 90% of its net tax-exempt interest income each taxable year. There are certain exceptions for failure to qualify if the failure is for reasonable cause or is de minimis, and certain corrective action is taken and certain tax payments are made by the Fund.

 

If the Fund were to fail to meet the qualifying income test or asset diversification test and fail to qualify as a RIC, it would be taxed in the same manner as an ordinary corporation, and distributions to its shareholders would not be deductible by the Fund in computing its taxable income, which would adversely affect the Fund’s performance.

Roundhill CRWD WeeklyPay™ ETF | LARGE SHAREHOLDER RISK  
Prospectus [Line Items]  
Risk [Text Block]

LARGE SHAREHOLDER RISK. Certain shareholders, including affiliated funds advised by the Adviser, may from time to time own a significant portion of the Fund’s shares. In addition, a third-party investor, the Adviser or an affiliate of the Adviser (“Affiliate”), an authorized participant, a market maker, or another entity may invest in the Fund and hold its investment for a limited period solely to facilitate the commencement of the Fund or to help the Fund achieve a specified size or scale. There can be no assurance that any large shareholder will not redeem its investment, that the size of the Fund will be maintained at such levels, or that the Fund will continue to meet applicable listing requirements. Redemptions by large shareholders could have a significant negative impact on the Fund. In addition, transactions by large shareholders may account for a large percentage of the trading volume on the Fund’s listing exchange and may, therefore, have a material upward or downward effect on the market price of the shares.

 

To the extent that a significant percentage of the Fund’s shares are owned or controlled by a small number of account shareholders (or a single account shareholder), including funds or accounts over which the Adviser or an Affiliate has investment discretion, the Fund is subject to the risk that those shareholders may purchase or redeem Fund shares in significant amounts rapidly or unexpectedly, including as a result of an asset allocation decision made by the Adviser or an Affiliate. This may adversely affect the Fund’s performance if the Adviser is forced to sell portfolio securities or invest cash when it would not otherwise choose to do so. Redemptions of a large number of shares may affect the liquidity of the Fund’s portfolio, increase the Fund’s transaction costs, and accelerate the realization of taxable income and/or gains. In addition, a large redemption could result in the Fund’s current expenses being allocated over a smaller asset base, leading to an increase in the Fund’s gross expense ratio. Large purchases of the Fund’s shares may also adversely affect the Fund’s performance to the extent that the Fund is delayed in investing new cash or otherwise maintains a larger cash position than it ordinarily would, particularly if the Fund accepts cash for an order for the purchase of creation units of the Fund’s shares.

Roundhill CRWD WeeklyPay™ ETF | CRWD INVESTING RISKS  
Prospectus [Line Items]  
Risk [Text Block]

CRWD INVESTING RISKS. The Fund will have significant exposure to CRWD through its investments in swap agreements that utilize CRWD as the reference asset. Accordingly, the Fund will subject to the risks of CRWD, set forth below.

 

CRWD ISSUER-SPECIFIC RISKS. Issuer-specific attributes may cause an investment held by the Fund to be more volatile than the market generally. The value of an individual security or particular type of security may be more volatile than the market as a whole and may perform differently from the value of the market as a whole. CRWD faces competition from established cybersecurity firms. Increased competition could lead to pricing pressure, market share losses and customer churn. The cybersecurity industry evolves rapidly, with new threats, AI-driven security advancements, and emerging attack vectors. Failure to innovate or adapt to evolving threats could weaken CRWD’s competitive position. CRWD’s business model relies heavily on recurring subscription-based revenue. Slower-than-expected customer acquisition or increased subscription cancellations could impact revenue growth and profitability. Despite being a cybersecurity company, CRWD itself is a target for cyberattacks, data breaches and hacking attempts. A significant security incident could damage customer trust, lead to regulatory scrutiny, and negatively impact its reputation. CRWD’s platform operates on cloud-based infrastructure, which relies on third-party providers. Any disruptions, outages, or security breaches at cloud service providers could impact CRWD’s ability to deliver its services. CRWD generates revenue from large enterprise and government contracts, which can be subject to long sales cycles, budget cuts, and renewal uncertainties. The demand for skilled cybersecurity professionals is high, and CRWD competes for top talent. Talent shortages, employee attrition, or failure to attract cybersecurity experts could impact innovation and service quality. CRWD must comply with global data privacy and cybersecurity laws, including General Data Protection Regulation (GDPR), California Consumer Privacy Act (CCPA), and evolving U.S. federal regulations. Failure to meet compliance standards could result in fines, legal actions, and restrictions on business operations. CRWD operates globally and may face risks from trade restrictions, data localization laws, and geopolitical tensions. Changes in international cybersecurity regulations could limit market access or increase compliance costs.

 

CYBERSECURITY COMPANIES RISK. Cybersecurity companies are companies that provide products and services intended to protect the integrity of data and network operations for private and public networks, computers and mobile devices. Like other types of technology and industrials companies, cybersecurity companies are generally subject to the risks of rapidly changing technologies, short product life cycles, fierce competition, aggressive pricing and reduced profit margins, loss of patent, copyright and trademark protections, cyclical market patterns, evolving industry standards and frequent new product introductions. These companies may also be smaller and less experienced companies, with limited product lines, markets, qualified personnel or financial resources. Such companies may not be exclusively or substantially exposed to companies that provide products or services intended to protect the integrity of data and network operations, but may be exposed to the market and business risks of other companies, industries or sectors, and the Fund may be adversely affected by negative developments impacting those other companies, industries and sectors.

 

INDIRECT INVESTMENT RISK. Crowdstrike Holdings, Inc. is not affiliated with the Trust, the Fund, the Adviser, the Sub-Adviser or any affiliates thereof and is not involved with this offering in any way, and has no obligation to consider the Fund in taking any corporate actions that might affect the value of the Fund. The Trust, the Fund, the Adviser, the Sub-Adviser or any affiliate are not responsible for the performance of CRWD and make no representation as to the performance of CRWD. Investing in the Fund is not equivalent to investing in CRWD. Fund shareholders will not have voting rights or rights to receive dividends or other distributions or any other rights with respect to CRWD.

 

INFORMATION TECHNOLOGY COMPANIES RISK. Information technology companies face intense competition, both domestically and internationally, which may have an adverse effect on profit margins. Like other technology companies, information technology companies may have limited product lines, markets, financial resources or personnel. The products of information technology companies may face obsolescence due to rapid technological developments, frequent new product introduction, unpredictable changes in growth rates and competition for the services of qualified personnel. Companies in the information technology sector are heavily dependent on patent and intellectual property rights. The loss or impairment of these rights may adversely affect the profitability of these companies. Information technology companies are facing increased government and regulatory scrutiny and may be subject to adverse government or regulatory action.

 

LARGE CAPITALIZATION COMPANIES RISK. Large capitalization companies may be less able than smaller capitalization companies to adapt to changing market conditions. Large capitalization companies may be more mature and subject to more limited growth potential compared with smaller capitalization companies. During different market cycles, the performance of large capitalization companies has trailed the overall performance of the broader securities markets.

 

UNITED STATES RISK. Certain changes in the U.S. economy, such as when the U.S. economy weakens or when its financial markets decline, may have an adverse effect on the securities to which the Fund has exposure.

Risk [Text Block]

NON-DIVERSIFICATION RISK. As a “non-diversified” fund, the Fund may hold a smaller number of portfolio securities than many other funds. To the extent the Fund invests in a relatively small number of issuers, a decline in the market value of a particular security held by the Fund may affect its value more than if it invested in a larger number of issuers. The value of the Fund Shares may be more volatile than the values of shares of more diversified funds.

Roundhill DKNG WeeklyPay™ ETF | MARKET RISK  
Prospectus [Line Items]  
Risk [Text Block]

MARKET RISK. Market risk is the risk that a particular investment, or Fund Shares in general, may fall in value. Securities are subject to market fluctuations caused by real or perceived adverse economic, political, and regulatory factors or market developments, changes in interest rates, disruptions to trade, impositions of tariffs and perceived trends in securities prices. Fund Shares could decline in value or underperform other investments. In addition, local, regional or global events such as war, acts of terrorism, market manipulation, government defaults, government shutdowns, regulatory actions, political changes, diplomatic developments, the imposition of sanctions and other similar measures, spread of infectious diseases or other public health issues, recessions, natural disasters, or other events could have a significant negative impact on the Fund and its investments. Any of such circumstances could have a materially negative impact on the value of Fund Shares, the liquidity of an investment, and may result in increased market volatility. During any such events, Fund Shares may trade at increased premiums or discounts to their net asset value, the bid/ask spread on Fund Shares may widen and the returns on investment may fluctuate.

Roundhill DKNG WeeklyPay™ ETF | LIQUIDITY RISK  
Prospectus [Line Items]  
Risk [Text Block]

LIQUIDITY RISK. The market for swap agreements that reference DKNG shares may be subject to periods of illiquidity. During such times it may be difficult or impossible to buy or sell a position at the desired price. Market disruptions or volatility can also make it difficult to find a counterparty willing to transact at a reasonable price and sufficient size. Illiquid markets may cause losses, which could be significant. The large size of the positions which the Fund may acquire increases the risk of illiquidity, may make its positions more difficult to liquidate, and may increase the losses incurred while trying to do so. Such large positions also may impact the price of swap agreements on DKNG shares.

Roundhill DKNG WeeklyPay™ ETF | ACTIVE MANAGEMENT RISK

Risk [Text Block]

ACTIVE MANAGEMENT RISK. The Fund is actively-managed and its performance reflects investment decisions that the Adviser and/or Sub-Adviser makes for the Fund. Such judgments about the Fund’s investments may prove to be incorrect. If the investments selected and the strategies employed by the Fund fail to produce the intended results, the Fund could underperform as compared to other funds with similar investment objectives and/or strategies, or could have negative returns.

Roundhill DKNG WeeklyPay™ ETF | ACTIVE MARKET RISK

ACTIVE MARKET RISK. Although Fund Shares are listed for trading on the Exchange, there can be no assurance that an active trading market for Fund Shares will develop or be maintained. Fund Shares trade on the Exchange at market prices that may be below, at or above the Fund’s net asset value. Securities, including Fund Shares, are subject to market fluctuations and liquidity constraints that may be caused by such factors as economic, political, or regulatory developments, changes in interest rates, and/or perceived trends in securities prices. Fund Shares could decline in value or underperform other investments.

Risk [Text Block]

CONCENTRATION RISK. The Fund is susceptible to an increased risk of loss, including losses due to adverse events that affect the Fund’s investments more than the market as a whole, to the extent that the Fund’s investments are concentrated in investments that provide exposure to DKNG and the industry to which it is assigned.

Roundhill DKNG WeeklyPay™ ETF | COUNTERPARTY RISK

Risk [Text Block]

COUNTERPARTY RISK. Fund transactions involving a counterparty are subject to the risk that the counterparty will not fulfill its obligation to the Fund. Counterparty risk may arise because of the counterparty’s financial condition (i.e., financial difficulties, bankruptcy, or insolvency), market activities and developments, or other reasons, whether foreseen or not. A counterparty’s inability to fulfill its obligation may result in significant financial loss to the Fund. The Fund may be unable to recover its investment from the counterparty or may obtain a limited recovery, and/or recovery may be delayed.

CREDIT RISK. An issuer or other obligated party of a debt security may be unable or unwilling to make dividend, interest and/or principal payments when due. In addition, the value of a debt security may decline because of concerns about the issuer’s ability or unwillingness to make such payments.

Roundhill DKNG WeeklyPay™ ETF | CURRENT MARKET CONDITIONS RISK  
Prospectus [Line Items]  
Risk [Text Block]

CURRENT MARKET CONDITIONS RISK. Current market conditions risk is the risk that a particular investment, or Fund Shares in general, may fall in value due to current market conditions. As a means to fight inflation, which remains at elevated levels, the Federal Reserve and certain foreign central banks have raised interest rates; however, the Federal Reserve has recently lowered interest rates and may continue to do so. U.S. regulators have proposed several changes to market and issuer regulations which would directly impact the Fund, and any regulatory changes could adversely impact the Fund’s ability to achieve its investment strategies or make certain investments. Recent and potential future bank failures could result in disruption to the broader banking industry or markets generally and reduce confidence in financial institutions and the economy as a whole, which may also heighten market volatility and reduce liquidity. Additionally, challenges in commercial real estate markets, including rising interest rates, declining valuations and increasing vacancies, could have a broader impact on financial markets. The ongoing adversarial political climate in the United States, as well as political and diplomatic events both domestic and abroad, have and may continue to have an adverse impact the U.S. regulatory landscape, markets and investor behavior, which could have a negative impact on the Fund’s investments and operations. The change in administration resulting from the 2024 United States national elections could result in significant impacts to international trade relations, tax and immigration policies, and other aspects of the national and international political and financial landscape, which could affect, among other things, inflation and the securities markets generally. Other unexpected political, regulatory and diplomatic events within the U.S. and abroad may affect investor and consumer confidence and may adversely impact financial markets and the broader economy. For example, ongoing armed conflicts between Russia and Ukraine in Europe and among Israel, Iran, Hamas and other militant groups in the Middle East, have caused and could continue to cause significant market disruptions and volatility within the markets in Russia, Europe, the Middle East and the United States. The hostilities and sanctions resulting from those hostilities have and could continue to have a significant impact on certain Fund investments as well as Fund performance and liquidity. The economies of the United States and its trading partners, as well as the financial markets generally, may be adversely impacted by trade disputes, including the imposition of tariffs, and other matters. For example, the United States has imposed trade barriers and restrictions on China. In addition, the Chinese government is engaged in a longstanding dispute with Taiwan, continually threatening an invasion. If the political climate between the United States and China does not improve or continues to deteriorate, if China were to attempt invading Taiwan, or if other geopolitical conflicts develop or worsen, economies, markets and individual securities may be adversely affected, and the value of the Fund’s assets may go down. A public health crisis and the ensuing policies enacted by governments and central banks may cause significant volatility and uncertainty in global financial markets, negatively impacting global growth prospects. As the COVID-19 global pandemic illustrated, such events may affect certain geographic regions, countries, sectors and industries more significantly than others. Advancements in technology may also adversely impact markets and the overall performance of the Fund. For instance, the economy may be significantly impacted by the advanced development and increased regulation of artificial intelligence. Additionally, cyber security breaches of both government and non-government entities could have negative impacts on infrastructure and the ability of such entities, including the Fund, to operate properly. These events, and any other future events, may adversely affect the prices and liquidity of the Fund’s portfolio investments and could result in disruptions in the trading markets.

Roundhill DKNG WeeklyPay™ ETF | CYBERSECURITY RISK  
Prospectus [Line Items]  
Risk [Text Block]

CYBERSECURITY RISK. Failures or breaches of the electronic systems of the Fund, the Fund’s adviser, sub-adviser, distributor and other service providers, market makers, Authorized Participants or the issuers of securities in which the Fund invests have the ability to cause disruptions, negatively impact the Fund’s business operations and/or potentially result in financial losses to the Fund and its shareholders. While the Fund has established business continuity plans and risk management systems seeking to address system breaches or failures, there are inherent limitations in such plans and systems. Furthermore, the Fund cannot control the cybersecurity plans and systems of the Fund’s other service providers, market makers, Authorized Participants or issuers of securities in which the Fund invests.

Roundhill DKNG WeeklyPay™ ETF | DEBT SECURITIES RISK  
Prospectus [Line Items]  
Risk [Text Block]

DEBT SECURITIES RISK. Investments in debt securities subject the holder to the credit risk of the issuer. Credit risk refers to the possibility that the issuer or other obligor of a security will not be able or willing to make payments of interest and principal when due. Generally, the value of debt securities will change inversely with changes in interest rates. To the extent that interest rates rise, certain underlying obligations may be paid off substantially slower than originally anticipated and the value of those securities may fall sharply. During periods of falling interest rates, the income received by the Fund may decline. If the principal on a debt security is prepaid before expected, the prepayments of principal may have to be reinvested in obligations paying interest at lower rates. Debt securities generally do not trade on a securities exchange making them generally less liquid and more difficult to value than common stock.

Roundhill DKNG WeeklyPay™ ETF | DERIVATIVES RISK  
Prospectus [Line Items]  
Risk [Text Block]

DERIVATIVES RISK. The use of derivative instruments involves risks different from, or possibly greater than, the risks associated with investing directly in securities and other traditional investments. These risks include: (i) the risk that the counterparty to a derivative transaction may not fulfill its contractual obligations; (ii) risk of mispricing or improper valuation; and (iii) the risk that changes in the value of the derivative may not correlate perfectly with the underlying asset. Derivative prices are highly volatile and may fluctuate substantially during a short period of time. Such prices are influenced by numerous factors that affect the markets, including, but not limited to: changing supply and demand relationships; government programs and policies; national and international political and economic events, changes in interest rates, inflation and deflation and changes in supply and demand relationships. Trading derivative instruments involves risks different from, or possibly greater than, the risks associated with investing directly in securities. Derivative contracts ordinarily have leverage inherent in their terms. The use of leverage may cause the Fund to liquidate portfolio positions when it would not be advantageous to do so in order to satisfy its obligations or to meet regulatory or contractual requirements for derivatives. The use of derivatives can magnify potential for gain or loss and, therefore, amplify the effects of market volatility on share price.

Roundhill DKNG WeeklyPay™ ETF | DISTRIBUTION TAX RISK  
Prospectus [Line Items]  
Risk [Text Block]

DISTRIBUTION TAX RISK. The Fund currently expects to make distributions on a weekly basis. Such frequent distributions may expose investors to increased tax liabilities. However, these distributions may exceed the Fund’s income and gains for the Fund’s taxable year. Distributions in excess of the Fund’s current and accumulated earnings and profits will be treated as a return of capital. A return of capital distribution generally will not be taxable but will reduce the shareholder’s cost basis and will result in a higher capital gain or lower capital loss when those Fund Shares on which the distribution was received are sold. Once a Fund shareholder’s cost basis is reduced to zero, further distributions will be treated as capital gain if the Fund shareholder holds Fund Shares as capital assets. Additionally, any capital returned through distributions will be distributed after payment of Fund fees and expenses. Because a portion of the Fund’s distributions may consist of return of capital, the Fund may not be an appropriate investment for investors who do not want their principal investment in the Fund to decrease over time or who do not wish to receive return of capital in a given period. In the event that a shareholder purchases Fund Shares shortly before a distribution by the Fund, the entire distribution may be taxable to the shareholder even though a portion of the distribution effectively represents a return of the purchase price.

Roundhill DKNG WeeklyPay™ ETF | ETF RISK  
Prospectus [Line Items]  
Risk [Text Block]

ETF RISK. The Fund may invest in ETFs. The value of an ETF held by the Fund will fluctuate over time based on fluctuations in the values of the assets held by the ETF, which may be affected by changes in general economic conditions, expectations for future growth and profits, interest rates and the supply and demand for those assets. When the Fund invests in an ETF, it will bear a proportionate share of the ETF’s expenses. Brokerage, tax and other expenses may negatively impact the performance of the ETF and, in turn, the value of the Fund Shares. An ETF that tracks an index may not exactly match the performance of the index due to cash drag, differences between the portfolio of the ETF and the components of the index, expenses and other factors.

Roundhill DKNG WeeklyPay™ ETF | INFLATION RISK  
Prospectus [Line Items]  
Risk [Text Block]

INFLATION RISK. Inflation risk is the risk that the value of assets or income from investments will be less in the future as inflation decreases the value of money. As inflation increases, the present value of the Fund’s assets and distributions may decline. This risk is more prevalent with respect to fixed income securities held by the Fund.

Roundhill DKNG WeeklyPay™ ETF | Interest Rate Risk [Member]  
Prospectus [Line Items]  
Risk [Text Block]

INTEREST RATE RISK. Interest rate risk is the risk that the value of the debt securities in the Fund’s portfolio will decline because of rising market interest rates. Interest rate risk is generally lower for shorter term debt securities and higher for longer-term debt securities. Duration is a reasonably accurate measure of a debt security’s price sensitivity to changes in interest rates and a common measure of interest rate risk. Duration measures a debt security’s expected life on a present value basis, taking into account the debt security’s yield, interest payments and final maturity. In general, duration represents the expected percentage change in the value of a security for an immediate 1% change in interest rates. For example, the price of a debt security with a three-year duration would be expected to drop by approximately 3% in response to a 1% increase in interest rates. Therefore, prices of debt securities with shorter durations tend to be less sensitive to interest rate changes than debt securities with longer durations. As the value of a debt security changes over time, so will its duration.

Roundhill DKNG WeeklyPay™ ETF | LEGISLATION AND LITIGATION RISK  
Prospectus [Line Items]  
Risk [Text Block]

LEGISLATION AND LITIGATION RISK. Legislation or litigation that affects the value of assets or securities held by the Fund may reduce the value of the Fund. From time to time, various legislative initiatives are proposed that may have a negative impact on certain assets or securities in which the Fund invests. In addition, litigation regarding any of the assets or securities owned by the Fund may negatively impact the value of the Shares. Such legislation or litigation may cause the Fund to lose value or may result in higher portfolio turnover if the Adviser determines to sell such a holding.

Roundhill DKNG WeeklyPay™ ETF | LEVERAGE RISK  
Prospectus [Line Items]  
Risk [Text Block]

LEVERAGE RISK. The Fund obtains investment exposure in excess of its net assets by utilizing leverage and may lose more money in market conditions that are adverse to its investment objectives than a fund that does not utilize leverage. An investment in the Fund is exposed to the risk that a decline in the weekly performance of shares of DKNG will be magnified. This means that an investment in the Fund will be reduced by an amount equal to 1.2% for every 1% weekly decline in the market value of the DKNG shares, not including the costs of financing leverage and other operating expenses, which would further reduce its value. The Fund could theoretically lose an amount greater than its net assets in the event the market value of DKNG shares decline more than 83.33% over a calendar week. Leverage will also have the effect of magnifying any differences in the Fund’s correlation with DKNG shares.

Roundhill DKNG WeeklyPay™ ETF | MONEY MARKET INSTRUMENTS RISK  
Prospectus [Line Items]  
Risk [Text Block]

MONEY MARKET INSTRUMENTS RISK. The value of money market instruments may be affected by changing interest rates and by changes in the credit ratings of the investments. If a significant amount of the Fund’s assets are invested in money market instruments, it will be more difficult for the Fund to achieve its investment objectives. An investment in a money market fund is not insured or guaranteed by the FDIC or any other government agency. It is possible to lose money by investing in a money market fund.

Roundhill DKNG WeeklyPay™ ETF | OPERATIONAL RISK  
Prospectus [Line Items]  
Risk [Text Block]

OPERATIONAL RISK. The Fund is subject to risks arising from various operational factors, including, but not limited to, human error, processing and communication errors, errors of the Fund’s service providers, counterparties or other third-parties, failed or inadequate processes and technology or systems failures. The Fund relies on third-parties for a range of services, including custody. Any delay or failure relating to engaging or maintaining such service providers may affect the Fund’s ability to meet its investment objectives. Although the Fund and the Adviser seek to reduce these operational risks through controls and procedures, there is no way to completely protect against such risks.

Roundhill DKNG WeeklyPay™ ETF | SPECIAL TAX RISK  
Prospectus [Line Items]  
Risk [Text Block]

SPECIAL TAX RISK. The Fund intends to qualify annually and to elect to be treated as a regulated investment company under the Internal Revenue Code of 1986, as amended (the “Code”). To qualify for the favorable U.S. federal income tax treatment generally accorded to regulated investment companies, the Fund must, among other things, (i) derive in each taxable year at least 90% of its gross income from dividends, interest, payments with respect to securities loans and gains from the sale or other disposition of stock, securities or foreign currencies or other income derived with respect to its business of investing in such stock, securities or currencies, or net income derived from interests in certain publicly traded partnerships; (ii) diversify its holdings so that, at the end of each quarter of the taxable year, (a) at least 50% of the market value of the Fund’s assets is represented by cash and cash items (including receivables), U.S. government securities, the securities of other regulated investment companies and other securities, with such other securities of any one issuer generally limited for the purposes of this calculation to an amount not greater than 5% of the value of the Fund’s total assets and not greater than 10% of the outstanding voting securities of such issuer, and (b) not more than 25% of the value of its total assets is invested in the securities (other than U.S. government securities or the securities of other regulated investment companies) of any one issuer, or two or more issuers which the Fund controls which are engaged in the same, similar or related trades or businesses, or the securities of one or more of certain publicly traded partnerships; and (iii) distribute at least 90% of its investment company taxable income (which includes, among other items, dividends, interest and net short-term capital gains in excess of net long-term capital losses) and at least 90% of its net tax-exempt interest income each taxable year. There are certain exceptions for failure to qualify if the failure is for reasonable cause or is de minimis, and certain corrective action is taken and certain tax payments are made by the Fund.

 

The authority with regard to swaps entered into by regulated investment companies is unclear both as to the qualification under the income test and the identification of the issuer under the diversification test. The Fund intends to take the position that because the swaps held by the Fund reference securities that the income on the swaps are “other income” from the Fund’s business of investing in stocks and securities. In addition, the Fund intends to manage its investments in the swaps so that neither the exposure to issuer of the referenced security nor the exposure to any one counterparty of the swaps will exceed 25% of the gross value of the Fund’s portfolio at the end of any quarter.

 

If the Fund were to fail to meet the qualifying income test or asset diversification test and fail to qualify as a RIC, it would be taxed in the same manner as an ordinary corporation, and distributions to its shareholders would not be deductible by the Fund in computing its taxable income, which would adversely affect the Fund’s performance.

Roundhill DKNG WeeklyPay™ ETF | STRUCTURAL ETF RISKS  
Prospectus [Line Items]  
Risk [Text Block]

STRUCTURAL ETF RISKS. The Fund is an ETF. Accordingly, it is subject to certain risks associated with its unique structure.

 

Market Participants Risk. Only an Authorized Participant may engage in creation or redemption transactions directly with the Fund, and none of those Authorized Participants is obligated to engage in creation and/or redemption transactions. The Fund has a limited number of institutions that may act as Authorized Participants on an agency basis (i.e., on behalf of other market participants). To the extent that Authorized Participants exit the business or are unable to proceed with creation or redemption orders with respect to the Fund and no other Authorized Participant is able to step forward to create or redeem, Fund Shares may be more likely to trade at a premium or discount to NAV and possibly face trading halts or delisting. The Fund may also rely on a small number of third-party market makers to provide a market for the purchase and sale of Fund Shares but such market makers are under no obligation to do so. Decisions by Authorized Participants or market makers to reduce their role or step away from these activities in times of market stress could inhibit the effectiveness of the arbitrage process in maintaining the relationship between the underlying values of the Fund’s portfolio securities and the Fund’s market price. Any trading halt or other problem relating to the trading activity of these market makers or any issues disrupting the Authorized Participants’ ability to proceed with creation and/or redemption orders could result in a dramatic change in the spread between the Fund’s net asset value and the price at which Fund Shares are trading on the Exchange, which could result in a decrease in value of Fund Shares. This reduced effectiveness could result in Fund Shares trading at a premium or discount to net asset value and also in greater than normal intraday bid-ask spreads Fund Shares.

 

Cash Transactions Risk. The Fund currently expects to effect a significant portion of its creations and redemptions for cash, rather than in-kind securities. Paying redemption proceeds in cash rather than through in-kind delivery of portfolio securities may require the Fund to dispose of or sell portfolio securities or other assets at an inopportune time to obtain the cash needed to meet redemption orders. This may cause the Fund to sell a security and recognize a capital gain or loss that might not have been incurred if it had made a redemption in-kind. As a result, the Fund may pay out higher or lower annual capital gains distributions than ETFs that redeem in-kind. The use of cash creations and redemptions may also cause the Fund’s Shares to trade in the market at greater bid-ask spreads or greater premiums or discounts to the Fund’s NAV. Furthermore, the Fund may not be able to execute cash transactions for creation and redemption purposes at the same price used to determine the Fund’s NAV. To the extent that the maximum additional charge for creation or redemption transactions is insufficient to cover the execution shortfall, the Fund’s performance could be negatively impacted.

 

Costs of Buying and Selling Fund Shares. Due to the costs of buying or selling Fund Shares, including brokerage commissions imposed by brokers and bid/ask spreads, frequent trading of Fund Shares may significantly reduce investment results and an investment in Fund Shares may not be advisable for investors who anticipate regularly making small investments.

 

Premium/Discount Risk. As with all ETFs, Fund Shares may be bought and sold in the secondary market at market prices. The trading prices of Fund Shares in the secondary market may differ from the Fund’s daily net asset value per share and there may be times when the market price of the shares is more than the net asset value per share (premium) or less than the net asset value per share (discount). If a shareholder purchases Fund Shares at a time when the market price is at a premium to the net asset value or sells Fund Shares at a time when the market price is at a discount to the net asset value, the shareholder may pay more for, or receive less than, the underlying value of the Fund Shares, respectively. This risk is heightened in times of market volatility or periods of steep market declines.

 

Trading Risks. Although Fund Shares are listed for trading on the Exchange and may be traded on U.S. exchanges other than the Exchange, there can be no assurance that Fund Shares will trade with any volume, or at all, on any stock exchange. In stressed market conditions, the liquidity of Fund Shares may begin to mirror the liquidity of the Fund’s underlying portfolio holdings, which can be significantly less liquid than Fund Shares. Trading in Fund Shares on the Exchange may be halted due to market conditions or for reasons that, in the view of the Exchange, make trading in Fund Shares inadvisable. In addition, trading in Fund Shares on the Exchange is subject to trading halts caused by extraordinary market volatility pursuant to the Exchange’s “circuit breaker” rules. There can be no assurance that the requirements of the Exchange necessary to maintain the listing of the Fund will continue to be met or will remain unchanged.

Roundhill DKNG WeeklyPay™ ETF | U.S. GOVERNMENT SECURITIES RISK  
Prospectus [Line Items]  
Risk [Text Block]

U.S. GOVERNMENT SECURITIES RISK. U.S. government securities are subject to interest rate risk but generally do not involve the credit risks associated with investments in other types of debt securities. As a result, the yields available from U.S. government securities are generally lower than the yields available from other debt securities. U.S. government securities are guaranteed only as to the timely payment of interest and the payment of principal when held to maturity.

Roundhill DKNG WeeklyPay™ ETF | VALUATION RISK  
Prospectus [Line Items]  
Risk [Text Block]

VALUATION RISK. The Fund may hold securities or other assets that may be valued on the basis of factors other than market quotations. This may occur because the asset or security does not trade on a centralized exchange, or in times of market turmoil or reduced liquidity. There are multiple methods that can be used to value a portfolio holding when market quotations are not readily available. The value established for any portfolio holding at a point in time might differ from what would be produced using a different methodology or if it had been priced using market quotations. Portfolio holdings that are valued using techniques other than market quotations, including “fair valued” assets or securities, may be subject to greater fluctuation in their valuations from one day to the next than if market quotations were used. In addition, there is no assurance that the Fund could sell or close out a portfolio position for the value established for it at any time, and it is possible that the Fund would incur a loss because a portfolio position is sold or closed out at a discount to the valuation established by the Fund at that time. The Fund’s ability to value investments may be impacted by technological issues or errors by pricing services or other third-party service providers.

Roundhill DKNG WeeklyPay™ ETF | EQUITY SECURITIES RISK  
Prospectus [Line Items]  
Risk [Text Block]

EQUITY SECURITIES RISK. Equity securities are subject to changes in value, and their values may be more volatile than those of other asset classes. Equity securities prices fluctuate for several reasons, including changes in investors’ perceptions of the financial condition of an issuer or the general condition of the relevant equity market, such as market volatility, or when political or economic events affecting an issuer occur. Common stock prices may be particularly sensitive to rising interest rates, as the cost of capital rises and borrowing costs increase. Common stocks generally subject their holders to more risks than preferred stocks and debt securities because common stockholders’ claims are subordinated to those of holders of preferred stocks and debt securities upon the bankruptcy of the issuer.

Roundhill DKNG WeeklyPay™ ETF | SWAP AGREEMENTS RISK  
Prospectus [Line Items]  
Risk [Text Block]

SWAP AGREEMENTS RISK. The Fund will utilize swap agreements to derive its exposure to shares of DKNG. Swap agreements may involve greater risks than direct investment in securities as they may be leveraged and are subject to credit risk, counterparty risk and valuation risk. A swap agreement could result in losses if the underlying reference or asset does not perform as anticipated. In addition, many swaps trade over-the-counter and may be considered illiquid. It may not be possible for the Fund to liquidate a swap position at an advantageous time or price, which may result in significant losses.

Roundhill DKNG WeeklyPay™ ETF | NEW FUND RISK

Prospectus [Line Items]  
Risk [Text Block]

REGULATED INVESTMENT COMPANY TAX RISKS. The Fund intends to qualify annually and to elect to be treated as a regulated investment company under the Internal Revenue Code of 1986, as amended (the “Code”). To qualify for the favorable U.S. federal income tax treatment generally accorded to regulated investment companies, the Fund must, among other things, (i) derive in each taxable year at least 90% of its gross income from dividends, interest, payments with respect to securities loans and gains from the sale or other disposition of stock, securities or foreign currencies or other income derived with respect to its business of investing in such stock, securities or currencies, or net income derived from interests in certain publicly traded partnerships; (ii) diversify its holdings so that, at the end of each quarter of the taxable year, (a) at least 50% of the market value of the Fund’s assets is represented by cash and cash items (including receivables), U.S. government securities, the securities of other regulated investment companies and other securities, with such other securities of any one issuer generally limited for the purposes of this calculation to an amount not greater than 5% of the value of the Fund’s total assets and not greater than 10% of the outstanding voting securities of such issuer, and (b) not more than 25% of the value of its total assets is invested in the securities (other than U.S. government securities or the securities of other regulated investment companies) of any one issuer, or two or more issuers which the Fund controls which are engaged in the same, similar or related trades or businesses, or the securities of one or more of certain publicly traded partnerships; and (iii) distribute at least 90% of its investment company taxable income (which includes, among other items, dividends, interest and net short-term capital gains in excess of net long-term capital losses) and at least 90% of its net tax-exempt interest income each taxable year. There are certain exceptions for failure to qualify if the failure is for reasonable cause or is de minimis, and certain corrective action is taken and certain tax payments are made by the Fund.

 

If the Fund were to fail to meet the qualifying income test or asset diversification test and fail to qualify as a RIC, it would be taxed in the same manner as an ordinary corporation, and distributions to its shareholders would not be deductible by the Fund in computing its taxable income, which would adversely affect the Fund’s performance.

Roundhill DKNG WeeklyPay™ ETF | LARGE SHAREHOLDER RISK  
Prospectus [Line Items]  
Risk [Text Block]

LARGE SHAREHOLDER RISK. Certain shareholders, including affiliated funds advised by the Adviser, may from time to time own a significant portion of the Fund’s shares. In addition, a third-party investor, the Adviser or an affiliate of the Adviser (“Affiliate”), an authorized participant, a market maker, or another entity may invest in the Fund and hold its investment for a limited period solely to facilitate the commencement of the Fund or to help the Fund achieve a specified size or scale. There can be no assurance that any large shareholder will not redeem its investment, that the size of the Fund will be maintained at such levels, or that the Fund will continue to meet applicable listing requirements. Redemptions by large shareholders could have a significant negative impact on the Fund. In addition, transactions by large shareholders may account for a large percentage of the trading volume on the Fund’s listing exchange and may, therefore, have a material upward or downward effect on the market price of the shares.

 

To the extent that a significant percentage of the Fund’s shares are owned or controlled by a small number of account shareholders (or a single account shareholder), including funds or accounts over which the Adviser or an Affiliate has investment discretion, the Fund is subject to the risk that those shareholders may purchase or redeem Fund shares in significant amounts rapidly or unexpectedly, including as a result of an asset allocation decision made by the Adviser or an Affiliate. This may adversely affect the Fund’s performance if the Adviser is forced to sell portfolio securities or invest cash when it would not otherwise choose to do so. Redemptions of a large number of shares may affect the liquidity of the Fund’s portfolio, increase the Fund’s transaction costs, and accelerate the realization of taxable income and/or gains. In addition, a large redemption could result in the Fund’s current expenses being allocated over a smaller asset base, leading to an increase in the Fund’s gross expense ratio. Large purchases of the Fund’s shares may also adversely affect the Fund’s performance to the extent that the Fund is delayed in investing new cash or otherwise maintains a larger cash position than it ordinarily would, particularly if the Fund accepts cash for an order for the purchase of creation units of the Fund’s shares.

DKNG INVESTING RISKS. The Fund will have significant exposure to DKNG through its investments in swap agreements that utilize DKNG as the reference asset. Accordingly, the Fund will subject to the risks of DKNG, set forth below.

 

DKNG ISSUER-SPECIFIC RISKS. Issuer-specific attributes may cause an investment held by the Fund to be more volatile than the market generally. The value of an individual security or particular type of security may be more volatile than the market as a whole and may perform differently from the value of the market as a whole. DKNG operates in a highly regulated industry, with varying legal frameworks across U.S. states and international markets. Changes in gambling laws, potential restrictions, or new compliance requirements could limit market expansion or increase operational costs. While sports betting is expanding at the state level, potential federal regulations or bans on certain betting activities could negatively impact DKNG’s business model. DKNG requires multiple licenses to operate in different jurisdictions. Regulatory issues or failure to maintain compliance with gaming laws could lead to fines, license revocations, or operational disruptions. DKNG’s business model is fully digital, making it dependent on app functionality, server reliability and payment processing systems. Any outages, technical failures, or cybersecurity breaches could result in lost revenue and reputational damage. Online gaming companies are frequent targets for hacking, data breaches, account takeovers, and fraud. A major cyberattack could compromise customer data and lead to legal liabilities. DKNG faces strong competition from other online and retail sportsbooks. Increased competition could lead to higher marketing expenses, customer acquisition costs, and pressure on margins. As more states legalize sports betting, competition may lead to slower user growth and increased costs to retain customers. Promotional offers and free bets may become less effective over time. DKNG’s revenue depends on consumer discretionary spending on entertainment and betting. Economic downturns, rising inflation, job losses, or reduced disposable income could lead to lower betting activity and user engagement. Expanding into international markets presents challenges related to local gambling laws, taxation, and regulatory hurdles. Changes in international gaming policies could impact revenue growth potential.

 

CONSUMER DISCRETIONARY COMPANIES RISK. The success of consumer product manufacturers and retailers is tied closely to the performance of domestic and international economies, interest rates, exchange rates, supply chains, competition, consumer confidence, changes in demographics and consumer preferences. Companies in the consumer discretionary sector depend heavily on disposable household income and consumer spending, and may be strongly affected by social trends and marketing campaigns. These companies may be subject to severe competition, which may have an adverse impact on their profitability.

 

GAMING COMPANIES RISK. Companies in the gaming industry include those engaged in casino operations, race track operations, sports and horse race betting operations, online gaming operations and/or the provision of related equipment and technologies. Companies in the gaming industry face intense competition, both domestically and internationally. Companies in the gaming industry are also highly regulated, and state and Federal legislative or regulatory changes and licensing issues (as well as the laws of other countries) can significantly impact their ability to operate in certain jurisdictions, the activities in which such companies are allowed to engage and the profitability of companies in the industry. Certain companies in the gaming industry are highly leveraged and have recently experienced financial difficulty. The gaming industry may also be negatively affected by changes in economic conditions, consumer tastes and discretionary income levels, intense competition, technological developments that may cause these companies to become obsolete quickly, financial resources, markets or personnel. In addition, the gaming industry is characterized by the use of various forms of intellectual property, which are dependent upon patented technologies, trademarked brands and proprietary information. Companies operating in the gaming industry are subject to the risk of significant litigation regarding intellectual property rights, which may adversely affect and financially harm such companies.

 

INDIRECT INVESTMENT RISK. DraftKings Inc. is not affiliated with the Trust, the Fund, the Adviser, the Sub-Adviser or any affiliates thereof and is not involved with this offering in any way, and has no obligation to consider the Fund in taking any corporate actions that might affect the value of the Fund. The Trust, the Fund, the Adviser, the Sub-Adviser or any affiliate are not responsible for the performance of DKNG and make no representation as to the performance of DKNG. Investing in the Fund is not equivalent to investing in DKNG. Fund shareholders will not have voting rights or rights to receive dividends or other distributions or any other rights with respect to DKNG.

 

LARGE CAPITALIZATION COMPANIES RISK. Large capitalization companies may be less able than smaller capitalization companies to adapt to changing market conditions. Large capitalization companies may be more mature and subject to more limited growth potential compared with smaller capitalization companies. During different market cycles, the performance of large capitalization companies has trailed the overall performance of the broader securities markets.

 

UNITED STATES RISK. Certain changes in the U.S. economy, such as when the U.S. economy weakens or when its financial markets decline, may have an adverse effect on the securities to which the Fund has exposure.

NON-DIVERSIFICATION RISK. As a “non-diversified” fund, the Fund may hold a smaller number of portfolio securities than many other funds. To the extent the Fund invests in a relatively small number of issuers, a decline in the market value of a particular security held by the Fund may affect its value more than if it invested in a larger number of issuers. The value of the Fund Shares may be more volatile than the values of shares of more diversified funds.

Roundhill HOOD WeeklyPay™ ETF | MARKET RISK  
Prospectus [Line Items]  
Risk [Text Block]

MARKET RISK. Market risk is the risk that a particular investment, or Fund Shares in general, may fall in value. Securities are subject to market fluctuations caused by real or perceived adverse economic, political, and regulatory factors or market developments, changes in interest rates, disruptions to trade, impositions of tariffs and perceived trends in securities prices. Fund Shares could decline in value or underperform other investments. In addition, local, regional or global events such as war, acts of terrorism, market manipulation, government defaults, government shutdowns, regulatory actions, political changes, diplomatic developments, the imposition of sanctions and other similar measures, spread of infectious diseases or other public health issues, recessions, natural disasters, or other events could have a significant negative impact on the Fund and its investments. Any of such circumstances could have a materially negative impact on the value of Fund Shares, the liquidity of an investment, and may result in increased market volatility. During any such events, Fund Shares may trade at increased premiums or discounts to their net asset value, the bid/ask spread on Fund Shares may widen and the returns on investment may fluctuate.

Roundhill HOOD WeeklyPay™ ETF | LIQUIDITY RISK  
Prospectus [Line Items]  
Risk [Text Block]

LIQUIDITY RISK. The market for swap agreements that reference HOOD shares may be subject to periods of illiquidity. During such times it may be difficult or impossible to buy or sell a position at the desired price. Market disruptions or volatility can also make it difficult to find a counterparty willing to transact at a reasonable price and sufficient size. Illiquid markets may cause losses, which could be significant. The large size of the positions which the Fund may acquire increases the risk of illiquidity, may make its positions more difficult to liquidate, and may increase the losses incurred while trying to do so. Such large positions also may impact the price of swap agreements on HOOD shares.

Roundhill HOOD WeeklyPay™ ETF | ACTIVE MANAGEMENT RISK  
Prospectus [Line Items]  
Risk [Text Block]

ACTIVE MANAGEMENT RISK. The Fund is actively-managed and its performance reflects investment decisions that the Adviser and/or Sub-Adviser makes for the Fund. Such judgments about the Fund’s investments may prove to be incorrect. If the investments selected and the strategies employed by the Fund fail to produce the intended results, the Fund could underperform as compared to other funds with similar investment objectives and/or strategies, or could have negative returns.

Roundhill HOOD WeeklyPay™ ETF | ACTIVE MARKET RISK

Risk [Text Block]

ACTIVE MARKET RISK. Although Fund Shares are listed for trading on the Exchange, there can be no assurance that an active trading market for Fund Shares will develop or be maintained. Fund Shares trade on the Exchange at market prices that may be below, at or above the Fund’s net asset value. Securities, including Fund Shares, are subject to market fluctuations and liquidity constraints that may be caused by such factors as economic, political, or regulatory developments, changes in interest rates, and/or perceived trends in securities prices. Fund Shares could decline in value or underperform other investments.

Roundhill HOOD WeeklyPay™ ETF | ASSET CLASS RISK

CONCENTRATION RISK. The Fund is susceptible to an increased risk of loss, including losses due to adverse events that affect the Fund’s investments more than the market as a whole, to the extent that the Fund’s investments are concentrated in investments that provide exposure to HOOD and the industry to which it is assigned.

Roundhill HOOD WeeklyPay™ ETF | COUNTERPARTY RISK  
Prospectus [Line Items]  
Risk [Text Block]

COUNTERPARTY RISK. Fund transactions involving a counterparty are subject to the risk that the counterparty will not fulfill its obligation to the Fund. Counterparty risk may arise because of the counterparty’s financial condition (i.e., financial difficulties, bankruptcy, or insolvency), market activities and developments, or other reasons, whether foreseen or not. A counterparty’s inability to fulfill its obligation may result in significant financial loss to the Fund. The Fund may be unable to recover its investment from the counterparty or may obtain a limited recovery, and/or recovery may be delayed.

CREDIT RISK. An issuer or other obligated party of a debt security may be unable or unwilling to make dividend, interest and/or principal payments when due. In addition, the value of a debt security may decline because of concerns about the issuer’s ability or unwillingness to make such payments.

Roundhill HOOD WeeklyPay™ ETF | CURRENT MARKET CONDITIONS RISK  
Prospectus [Line Items]  
Risk [Text Block]

CURRENT MARKET CONDITIONS RISK. Current market conditions risk is the risk that a particular investment, or Fund Shares in general, may fall in value due to current market conditions. As a means to fight inflation, which remains at elevated levels, the Federal Reserve and certain foreign central banks have raised interest rates; however, the Federal Reserve has recently lowered interest rates and may continue to do so. U.S. regulators have proposed several changes to market and issuer regulations which would directly impact the Fund, and any regulatory changes could adversely impact the Fund’s ability to achieve its investment strategies or make certain investments. Recent and potential future bank failures could result in disruption to the broader banking industry or markets generally and reduce confidence in financial institutions and the economy as a whole, which may also heighten market volatility and reduce liquidity. Additionally, challenges in commercial real estate markets, including rising interest rates, declining valuations and increasing vacancies, could have a broader impact on financial markets. The ongoing adversarial political climate in the United States, as well as political and diplomatic events both domestic and abroad, have and may continue to have an adverse impact the U.S. regulatory landscape, markets and investor behavior, which could have a negative impact on the Fund’s investments and operations. The change in administration resulting from the 2024 United States national elections could result in significant impacts to international trade relations, tax and immigration policies, and other aspects of the national and international political and financial landscape, which could affect, among other things, inflation and the securities markets generally. Other unexpected political, regulatory and diplomatic events within the U.S. and abroad may affect investor and consumer confidence and may adversely impact financial markets and the broader economy. For example, ongoing armed conflicts between Russia and Ukraine in Europe and among Israel, Iran, Hamas and other militant groups in the Middle East, have caused and could continue to cause significant market disruptions and volatility within the markets in Russia, Europe, the Middle East and the United States. The hostilities and sanctions resulting from those hostilities have and could continue to have a significant impact on certain Fund investments as well as Fund performance and liquidity. The economies of the United States and its trading partners, as well as the financial markets generally, may be adversely impacted by trade disputes, including the imposition of tariffs, and other matters. For example, the United States has imposed trade barriers and restrictions on China. In addition, the Chinese government is engaged in a longstanding dispute with Taiwan, continually threatening an invasion. If the political climate between the United States and China does not improve or continues to deteriorate, if China were to attempt invading Taiwan, or if other geopolitical conflicts develop or worsen, economies, markets and individual securities may be adversely affected, and the value of the Fund’s assets may go down. A public health crisis and the ensuing policies enacted by governments and central banks may cause significant volatility and uncertainty in global financial markets, negatively impacting global growth prospects. As the COVID-19 global pandemic illustrated, such events may affect certain geographic regions, countries, sectors and industries more significantly than others. Advancements in technology may also adversely impact markets and the overall performance of the Fund. For instance, the economy may be significantly impacted by the advanced development and increased regulation of artificial intelligence. Additionally, cyber security breaches of both government and non-government entities could have negative impacts on infrastructure and the ability of such entities, including the Fund, to operate properly. These events, and any other future events, may adversely affect the prices and liquidity of the Fund’s portfolio investments and could result in disruptions in the trading markets.

Roundhill HOOD WeeklyPay™ ETF | CYBERSECURITY RISK  
Prospectus [Line Items]  
Risk [Text Block]

CYBERSECURITY RISK. Failures or breaches of the electronic systems of the Fund, the Fund’s adviser, sub-adviser, distributor and other service providers, market makers, Authorized Participants or the issuers of securities in which the Fund invests have the ability to cause disruptions, negatively impact the Fund’s business operations and/or potentially result in financial losses to the Fund and its shareholders. While the Fund has established business continuity plans and risk management systems seeking to address system breaches or failures, there are inherent limitations in such plans and systems. Furthermore, the Fund cannot control the cybersecurity plans and systems of the Fund’s other service providers, market makers, Authorized Participants or issuers of securities in which the Fund invests.

Roundhill HOOD WeeklyPay™ ETF | DEBT SECURITIES RISK  
Prospectus [Line Items]  
Risk [Text Block]

DEBT SECURITIES RISK. Investments in debt securities subject the holder to the credit risk of the issuer. Credit risk refers to the possibility that the issuer or other obligor of a security will not be able or willing to make payments of interest and principal when due. Generally, the value of debt securities will change inversely with changes in interest rates. To the extent that interest rates rise, certain underlying obligations may be paid off substantially slower than originally anticipated and the value of those securities may fall sharply. During periods of falling interest rates, the income received by the Fund may decline. If the principal on a debt security is prepaid before expected, the prepayments of principal may have to be reinvested in obligations paying interest at lower rates. Debt securities generally do not trade on a securities exchange making them generally less liquid and more difficult to value than common stock.

Roundhill HOOD WeeklyPay™ ETF | DERIVATIVES RISK  
Prospectus [Line Items]  
Risk [Text Block]

DERIVATIVES RISK. The use of derivative instruments involves risks different from, or possibly greater than, the risks associated with investing directly in securities and other traditional investments. These risks include: (i) the risk that the counterparty to a derivative transaction may not fulfill its contractual obligations; (ii) risk of mispricing or improper valuation; and (iii) the risk that changes in the value of the derivative may not correlate perfectly with the underlying asset. Derivative prices are highly volatile and may fluctuate substantially during a short period of time. Such prices are influenced by numerous factors that affect the markets, including, but not limited to: changing supply and demand relationships; government programs and policies; national and international political and economic events, changes in interest rates, inflation and deflation and changes in supply and demand relationships. Trading derivative instruments involves risks different from, or possibly greater than, the risks associated with investing directly in securities. Derivative contracts ordinarily have leverage inherent in their terms. The use of leverage may cause the Fund to liquidate portfolio positions when it would not be advantageous to do so in order to satisfy its obligations or to meet regulatory or contractual requirements for derivatives. The use of derivatives can magnify potential for gain or loss and, therefore, amplify the effects of market volatility on share price.

Roundhill HOOD WeeklyPay™ ETF | DISTRIBUTION TAX RISK  
Prospectus [Line Items]  
Risk [Text Block]

DISTRIBUTION TAX RISK. The Fund currently expects to make distributions on a weekly basis. Such frequent distributions may expose investors to increased tax liabilities. However, these distributions may exceed the Fund’s income and gains for the Fund’s taxable year. Distributions in excess of the Fund’s current and accumulated earnings and profits will be treated as a return of capital. A return of capital distribution generally will not be taxable but will reduce the shareholder’s cost basis and will result in a higher capital gain or lower capital loss when those Fund Shares on which the distribution was received are sold. Once a Fund shareholder’s cost basis is reduced to zero, further distributions will be treated as capital gain if the Fund shareholder holds Fund Shares as capital assets. Additionally, any capital returned through distributions will be distributed after payment of Fund fees and expenses. Because a portion of the Fund’s distributions may consist of return of capital, the Fund may not be an appropriate investment for investors who do not want their principal investment in the Fund to decrease over time or who do not wish to receive return of capital in a given period. In the event that a shareholder purchases Fund Shares shortly before a distribution by the Fund, the entire distribution may be taxable to the shareholder even though a portion of the distribution effectively represents a return of the purchase price.

Roundhill HOOD WeeklyPay™ ETF | ETF RISK  
Prospectus [Line Items]  
Risk [Text Block]

ETF RISK. The Fund may invest in ETFs. The value of an ETF held by the Fund will fluctuate over time based on fluctuations in the values of the assets held by the ETF, which may be affected by changes in general economic conditions, expectations for future growth and profits, interest rates and the supply and demand for those assets. When the Fund invests in an ETF, it will bear a proportionate share of the ETF’s expenses. Brokerage, tax and other expenses may negatively impact the performance of the ETF and, in turn, the value of the Fund Shares. An ETF that tracks an index may not exactly match the performance of the index due to cash drag, differences between the portfolio of the ETF and the components of the index, expenses and other factors.

Roundhill HOOD WeeklyPay™ ETF | INFLATION RISK  
Prospectus [Line Items]  
Risk [Text Block]

INFLATION RISK. Inflation risk is the risk that the value of assets or income from investments will be less in the future as inflation decreases the value of money. As inflation increases, the present value of the Fund’s assets and distributions may decline. This risk is more prevalent with respect to fixed income securities held by the Fund.

Roundhill HOOD WeeklyPay™ ETF | Interest Rate Risk [Member]  
Prospectus [Line Items]  
Risk [Text Block]

INTEREST RATE RISK. Interest rate risk is the risk that the value of the debt securities in the Fund’s portfolio will decline because of rising market interest rates. Interest rate risk is generally lower for shorter term debt securities and higher for longer-term debt securities. Duration is a reasonably accurate measure of a debt security’s price sensitivity to changes in interest rates and a common measure of interest rate risk. Duration measures a debt security’s expected life on a present value basis, taking into account the debt security’s yield, interest payments and final maturity. In general, duration represents the expected percentage change in the value of a security for an immediate 1% change in interest rates. For example, the price of a debt security with a three-year duration would be expected to drop by approximately 3% in response to a 1% increase in interest rates. Therefore, prices of debt securities with shorter durations tend to be less sensitive to interest rate changes than debt securities with longer durations. As the value of a debt security changes over time, so will its duration.

Roundhill HOOD WeeklyPay™ ETF | LEGISLATION AND LITIGATION RISK  
Prospectus [Line Items]  
Risk [Text Block]

LEGISLATION AND LITIGATION RISK. Legislation or litigation that affects the value of assets or securities held by the Fund may reduce the value of the Fund. From time to time, various legislative initiatives are proposed that may have a negative impact on certain assets or securities in which the Fund invests. In addition, litigation regarding any of the assets or securities owned by the Fund may negatively impact the value of the Shares. Such legislation or litigation may cause the Fund to lose value or may result in higher portfolio turnover if the Adviser determines to sell such a holding.

Roundhill HOOD WeeklyPay™ ETF | LEVERAGE RISK  
Prospectus [Line Items]  
Risk [Text Block]

LEVERAGE RISK. The Fund obtains investment exposure in excess of its net assets by utilizing leverage and may lose more money in market conditions that are adverse to its investment objectives than a fund that does not utilize leverage. An investment in the Fund is exposed to the risk that a decline in the weekly performance of shares of HOOD will be magnified. This means that an investment in the Fund will be reduced by an amount equal to 1.2% for every 1% weekly decline in the market value of the HOOD shares, not including the costs of financing leverage and other operating expenses, which would further reduce its value. The Fund could theoretically lose an amount greater than its net assets in the event the market value of HOOD shares decline more than 83.33% over a calendar week. Leverage will also have the effect of magnifying any differences in the Fund’s correlation with HOOD shares.

Roundhill HOOD WeeklyPay™ ETF | MONEY MARKET INSTRUMENTS RISK  
Prospectus [Line Items]  
Risk [Text Block]

MONEY MARKET INSTRUMENTS RISK. The value of money market instruments may be affected by changing interest rates and by changes in the credit ratings of the investments. If a significant amount of the Fund’s assets are invested in money market instruments, it will be more difficult for the Fund to achieve its investment objectives. An investment in a money market fund is not insured or guaranteed by the FDIC or any other government agency. It is possible to lose money by investing in a money market fund.

Roundhill HOOD WeeklyPay™ ETF | OPERATIONAL RISK  
Prospectus [Line Items]  
Risk [Text Block]

OPERATIONAL RISK. The Fund is subject to risks arising from various operational factors, including, but not limited to, human error, processing and communication errors, errors of the Fund’s service providers, counterparties or other third-parties, failed or inadequate processes and technology or systems failures. The Fund relies on third-parties for a range of services, including custody. Any delay or failure relating to engaging or maintaining such service providers may affect the Fund’s ability to meet its investment objectives. Although the Fund and the Adviser seek to reduce these operational risks through controls and procedures, there is no way to completely protect against such risks.

Roundhill HOOD WeeklyPay™ ETF | SPECIAL TAX RISK  
Prospectus [Line Items]  
Risk [Text Block]

SPECIAL TAX RISK. The Fund intends to qualify annually and to elect to be treated as a regulated investment company under the Internal Revenue Code of 1986, as amended (the “Code”). To qualify for the favorable U.S. federal income tax treatment generally accorded to regulated investment companies, the Fund must, among other things, (i) derive in each taxable year at least 90% of its gross income from dividends, interest, payments with respect to securities loans and gains from the sale or other disposition of stock, securities or foreign currencies or other income derived with respect to its business of investing in such stock, securities or currencies, or net income derived from interests in certain publicly traded partnerships; (ii) diversify its holdings so that, at the end of each quarter of the taxable year, (a) at least 50% of the market value of the Fund’s assets is represented by cash and cash items (including receivables), U.S. government securities, the securities of other regulated investment companies and other securities, with such other securities of any one issuer generally limited for the purposes of this calculation to an amount not greater than 5% of the value of the Fund’s total assets and not greater than 10% of the outstanding voting securities of such issuer, and (b) not more than 25% of the value of its total assets is invested in the securities (other than U.S. government securities or the securities of other regulated investment companies) of any one issuer, or two or more issuers which the Fund controls which are engaged in the same, similar or related trades or businesses, or the securities of one or more of certain publicly traded partnerships; and (iii) distribute at least 90% of its investment company taxable income (which includes, among other items, dividends, interest and net short-term capital gains in excess of net long-term capital losses) and at least 90% of its net tax-exempt interest income each taxable year. There are certain exceptions for failure to qualify if the failure is for reasonable cause or is de minimis, and certain corrective action is taken and certain tax payments are made by the Fund.

 

The authority with regard to swaps entered into by regulated investment companies is unclear both as to the qualification under the income test and the identification of the issuer under the diversification test. The Fund intends to take the position that because the swaps held by the Fund reference securities that the income on the swaps are “other income” from the Fund’s business of investing in stocks and securities. In addition, the Fund intends to manage its investments in the swaps so that neither the exposure to issuer of the referenced security nor the exposure to any one counterparty of the swaps will exceed 25% of the gross value of the Fund’s portfolio at the end of any quarter.

 

If the Fund were to fail to meet the qualifying income test or asset diversification test and fail to qualify as a RIC, it would be taxed in the same manner as an ordinary corporation, and distributions to its shareholders would not be deductible by the Fund in computing its taxable income, which would adversely affect the Fund’s performance.

Roundhill HOOD WeeklyPay™ ETF | STRUCTURAL ETF RISKS  
Prospectus [Line Items]  
Risk [Text Block]

STRUCTURAL ETF RISKS. The Fund is an ETF. Accordingly, it is subject to certain risks associated with its unique structure.

 

Market Participants Risk. Only an Authorized Participant may engage in creation or redemption transactions directly with the Fund, and none of those Authorized Participants is obligated to engage in creation and/or redemption transactions. The Fund has a limited number of institutions that may act as Authorized Participants on an agency basis (i.e., on behalf of other market participants). To the extent that Authorized Participants exit the business or are unable to proceed with creation or redemption orders with respect to the Fund and no other Authorized Participant is able to step forward to create or redeem, Fund Shares may be more likely to trade at a premium or discount to NAV and possibly face trading halts or delisting. The Fund may also rely on a small number of third-party market makers to provide a market for the purchase and sale of Fund Shares but such market makers are under no obligation to do so. Decisions by Authorized Participants or market makers to reduce their role or step away from these activities in times of market stress could inhibit the effectiveness of the arbitrage process in maintaining the relationship between the underlying values of the Fund’s portfolio securities and the Fund’s market price. Any trading halt or other problem relating to the trading activity of these market makers or any issues disrupting the Authorized Participants’ ability to proceed with creation and/or redemption orders could result in a dramatic change in the spread between the Fund’s net asset value and the price at which Fund Shares are trading on the Exchange, which could result in a decrease in value of Fund Shares. This reduced effectiveness could result in Fund Shares trading at a premium or discount to net asset value and also in greater than normal intraday bid-ask spreads Fund Shares.

 

Cash Transactions Risk. The Fund currently expects to effect a significant portion of its creations and redemptions for cash, rather than in-kind securities. Paying redemption proceeds in cash rather than through in-kind delivery of portfolio securities may require the Fund to dispose of or sell portfolio securities or other assets at an inopportune time to obtain the cash needed to meet redemption orders. This may cause the Fund to sell a security and recognize a capital gain or loss that might not have been incurred if it had made a redemption in-kind. As a result, the Fund may pay out higher or lower annual capital gains distributions than ETFs that redeem in-kind. The use of cash creations and redemptions may also cause the Fund’s Shares to trade in the market at greater bid-ask spreads or greater premiums or discounts to the Fund’s NAV. Furthermore, the Fund may not be able to execute cash transactions for creation and redemption purposes at the same price used to determine the Fund’s NAV. To the extent that the maximum additional charge for creation or redemption transactions is insufficient to cover the execution shortfall, the Fund’s performance could be negatively impacted.

 

Costs of Buying and Selling Fund Shares. Due to the costs of buying or selling Fund Shares, including brokerage commissions imposed by brokers and bid/ask spreads, frequent trading of Fund Shares may significantly reduce investment results and an investment in Fund Shares may not be advisable for investors who anticipate regularly making small investments.

 

Premium/Discount Risk. As with all ETFs, Fund Shares may be bought and sold in the secondary market at market prices. The trading prices of Fund Shares in the secondary market may differ from the Fund’s daily net asset value per share and there may be times when the market price of the shares is more than the net asset value per share (premium) or less than the net asset value per share (discount). If a shareholder purchases Fund Shares at a time when the market price is at a premium to the net asset value or sells Fund Shares at a time when the market price is at a discount to the net asset value, the shareholder may pay more for, or receive less than, the underlying value of the Fund Shares, respectively. This risk is heightened in times of market volatility or periods of steep market declines.

 

Trading Risks. Although Fund Shares are listed for trading on the Exchange and may be traded on U.S. exchanges other than the Exchange, there can be no assurance that Fund Shares will trade with any volume, or at all, on any stock exchange. In stressed market conditions, the liquidity of Fund Shares may begin to mirror the liquidity of the Fund’s underlying portfolio holdings, which can be significantly less liquid than Fund Shares. Trading in Fund Shares on the Exchange may be halted due to market conditions or for reasons that, in the view of the Exchange, make trading in Fund Shares inadvisable. In addition, trading in Fund Shares on the Exchange is subject to trading halts caused by extraordinary market volatility pursuant to the Exchange’s “circuit breaker” rules. There can be no assurance that the requirements of the Exchange necessary to maintain the listing of the Fund will continue to be met or will remain unchanged.

Roundhill HOOD WeeklyPay™ ETF | U.S. GOVERNMENT SECURITIES RISK  
Prospectus [Line Items]  
Risk [Text Block]

U.S. GOVERNMENT SECURITIES RISK. U.S. government securities are subject to interest rate risk but generally do not involve the credit risks associated with investments in other types of debt securities. As a result, the yields available from U.S. government securities are generally lower than the yields available from other debt securities. U.S. government securities are guaranteed only as to the timely payment of interest and the payment of principal when held to maturity.

Roundhill HOOD WeeklyPay™ ETF | VALUATION RISK  
Prospectus [Line Items]  
Risk [Text Block]

VALUATION RISK. The Fund may hold securities or other assets that may be valued on the basis of factors other than market quotations. This may occur because the asset or security does not trade on a centralized exchange, or in times of market turmoil or reduced liquidity. There are multiple methods that can be used to value a portfolio holding when market quotations are not readily available. The value established for any portfolio holding at a point in time might differ from what would be produced using a different methodology or if it had been priced using market quotations. Portfolio holdings that are valued using techniques other than market quotations, including “fair valued” assets or securities, may be subject to greater fluctuation in their valuations from one day to the next than if market quotations were used. In addition, there is no assurance that the Fund could sell or close out a portfolio position for the value established for it at any time, and it is possible that the Fund would incur a loss because a portfolio position is sold or closed out at a discount to the valuation established by the Fund at that time. The Fund’s ability to value investments may be impacted by technological issues or errors by pricing services or other third-party service providers.

Roundhill HOOD WeeklyPay™ ETF | EQUITY SECURITIES RISK  
Prospectus [Line Items]  
Risk [Text Block]

EQUITY SECURITIES RISK. Equity securities are subject to changes in value, and their values may be more volatile than those of other asset classes. Equity securities prices fluctuate for several reasons, including changes in investors’ perceptions of the financial condition of an issuer or the general condition of the relevant equity market, such as market volatility, or when political or economic events affecting an issuer occur. Common stock prices may be particularly sensitive to rising interest rates, as the cost of capital rises and borrowing costs increase. Common stocks generally subject their holders to more risks than preferred stocks and debt securities because common stockholders’ claims are subordinated to those of holders of preferred stocks and debt securities upon the bankruptcy of the issuer.

Roundhill HOOD WeeklyPay™ ETF | SWAP AGREEMENTS RISK  
Prospectus [Line Items]  
Risk [Text Block]

SWAP AGREEMENTS RISK. The Fund will utilize swap agreements to derive its exposure to shares of HOOD. Swap agreements may involve greater risks than direct investment in securities as they may be leveraged and are subject to credit risk, counterparty risk and valuation risk. A swap agreement could result in losses if the underlying reference or asset does not perform as anticipated. In addition, many swaps trade over-the-counter and may be considered illiquid. It may not be possible for the Fund to liquidate a swap position at an advantageous time or price, which may result in significant losses.

Roundhill HOOD WeeklyPay™ ETF | REGULATED INVESTMENT COMPANY TAX RISKS  
Prospectus [Line Items]  
Risk [Text Block]

REGULATED INVESTMENT COMPANY TAX RISKS. The Fund intends to qualify annually and to elect to be treated as a regulated investment company under the Internal Revenue Code of 1986, as amended (the “Code”). To qualify for the favorable U.S. federal income tax treatment generally accorded to regulated investment companies, the Fund must, among other things, (i) derive in each taxable year at least 90% of its gross income from dividends, interest, payments with respect to securities loans and gains from the sale or other disposition of stock, securities or foreign currencies or other income derived with respect to its business of investing in such stock, securities or currencies, or net income derived from interests in certain publicly traded partnerships; (ii) diversify its holdings so that, at the end of each quarter of the taxable year, (a) at least 50% of the market value of the Fund’s assets is represented by cash and cash items (including receivables), U.S. government securities, the securities of other regulated investment companies and other securities, with such other securities of any one issuer generally limited for the purposes of this calculation to an amount not greater than 5% of the value of the Fund’s total assets and not greater than 10% of the outstanding voting securities of such issuer, and (b) not more than 25% of the value of its total assets is invested in the securities (other than U.S. government securities or the securities of other regulated investment companies) of any one issuer, or two or more issuers which the Fund controls which are engaged in the same, similar or related trades or businesses, or the securities of one or more of certain publicly traded partnerships; and (iii) distribute at least 90% of its investment company taxable income (which includes, among other items, dividends, interest and net short-term capital gains in excess of net long-term capital losses) and at least 90% of its net tax-exempt interest income each taxable year. There are certain exceptions for failure to qualify if the failure is for reasonable cause or is de minimis, and certain corrective action is taken and certain tax payments are made by the Fund.

 

If the Fund were to fail to meet the qualifying income test or asset diversification test and fail to qualify as a RIC, it would be taxed in the same manner as an ordinary corporation, and distributions to its shareholders would not be deductible by the Fund in computing its taxable income, which would adversely affect the Fund’s performance.

Roundhill HOOD WeeklyPay™ ETF | LARGE SHAREHOLDER RISK  
Prospectus [Line Items]  
Risk [Text Block]

LARGE SHAREHOLDER RISK. Certain shareholders, including affiliated funds advised by the Adviser, may from time to time own a significant portion of the Fund’s shares. In addition, a third-party investor, the Adviser or an affiliate of the Adviser (“Affiliate”), an authorized participant, a market maker, or another entity may invest in the Fund and hold its investment for a limited period solely to facilitate the commencement of the Fund or to help the Fund achieve a specified size or scale. There can be no assurance that any large shareholder will not redeem its investment, that the size of the Fund will be maintained at such levels, or that the Fund will continue to meet applicable listing requirements. Redemptions by large shareholders could have a significant negative impact on the Fund. In addition, transactions by large shareholders may account for a large percentage of the trading volume on the Fund’s listing exchange and may, therefore, have a material upward or downward effect on the market price of the shares.

 

To the extent that a significant percentage of the Fund’s shares are owned or controlled by a small number of account shareholders (or a single account shareholder), including funds or accounts over which the Adviser or an Affiliate has investment discretion, the Fund is subject to the risk that those shareholders may purchase or redeem Fund shares in significant amounts rapidly or unexpectedly, including as a result of an asset allocation decision made by the Adviser or an Affiliate. This may adversely affect the Fund’s performance if the Adviser is forced to sell portfolio securities or invest cash when it would not otherwise choose to do so. Redemptions of a large number of shares may affect the liquidity of the Fund’s portfolio, increase the Fund’s transaction costs, and accelerate the realization of taxable income and/or gains. In addition, a large redemption could result in the Fund’s current expenses being allocated over a smaller asset base, leading to an increase in the Fund’s gross expense ratio. Large purchases of the Fund’s shares may also adversely affect the Fund’s performance to the extent that the Fund is delayed in investing new cash or otherwise maintains a larger cash position than it ordinarily would, particularly if the Fund accepts cash for an order for the purchase of creation units of the Fund’s shares.

Roundhill HOOD WeeklyPay™ ETF | HOOD INVESTING RISKS  
Prospectus [Line Items]  
Risk [Text Block]

HOOD INVESTING RISKS. The Fund will have significant exposure to HOOD through its investments in swap agreements that utilize HOOD as the reference asset. Accordingly, the Fund will subject to the risks of HOOD, set forth below.

 

HOOD ISSUER-SPECIFIC RISKS. Issuer-specific attributes may cause an investment held by the Fund to be more volatile than the market generally. The value of an individual security or particular type of security may be more volatile than the market as a whole and may perform differently from the value of the market as a whole. HOOD competes with traditional brokerages and fintech rivals. Increased competition may lead to pricing pressures, customer churn and the need for costly product innovations. A large portion of HOOD’s revenue comes from options and crypto trading, which are highly volatile. Changes in trading behavior, regulatory actions or customer attrition could materially impact earnings. HOOD also generates income from margin lending and interest on customer cash balances. Rising interest rates may improve margins, but they could also reduce borrowing demand and market participation, negatively impacting trading volume. HOOD has experienced trading outages and technical failures, particularly during periods of high market volatility. These disruptions have resulted in customer complaints, regulatory fines, and lawsuits, posing a significant operational risk. As a digital brokerage, HOOD is exposed to hacking attempts, account breaches, and identity theft risks. A significant security incident could harm user trust and lead to regulatory consequences. HOOD routes trades through third-party market makers. If key partners face financial distress or regulatory scrutiny, HOOD’s ability to execute trades efficiently could be impacted. HOOD operates in the highly regulated brokerage and financial services industry, subject to oversight from the SEC, FINRA, and other regulatory bodies. Changes in financial regulations could increase compliance costs, limit business practices, or lead to operational restrictions. HOOD has faced multiple class-action lawsuits, regulatory fines, and customer complaints related to trading outages, margin lending practices, and risk disclosures. Any further legal actions could result in financial penalties and reputational damage. A significant portion of HOOD’s revenue comes from payment for order flow, which has been criticized by regulators. A potential ban or restriction on payment for order flow could impact HOOD’s business model and revenue stream. HOOD’s customer base is primarily retail investors, who may trade less frequently during economic downturns or bearish markets. A decline in speculative trading activity could reduce revenue.

 

FINANCIAL COMPANIES RISK. Companies in the financials sector are subject to extensive governmental regulation and intervention, which may adversely affect the scope of their activities, the prices they can charge, the amount of capital and liquid assets they must maintain and, potentially, their size. Governmental regulation may change frequently and may have significant adverse consequences for companies in the financials sector, including effects not intended by such regulation. Increased risk taking by financial companies may also result in greater overall risk in the U.S. and global financials sector. The impact of changes in capital requirements, or recent or future regulation in various countries, on any individual financial company or on the financials sector as a whole cannot be predicted.

 

Certain risks may impact the value of investments in the financials sector more severely than those of investments outside this sector, including the risks associated with companies that operate with substantial financial leverage. Companies in the financials sector are exposed directly to the credit risk of their borrowers and counterparties, who may be leveraged to an unknown degree, including through swaps and other derivatives products. Financial services companies may have significant exposure to the same borrowers and counterparties, with the result that a borrower’s or counterparty’s inability to meet its obligations to one company may affect other companies with exposure to the same borrower or counterparty. This interconnectedness of risk may result in significant negative impacts to companies with direct exposure to the defaulting counterparty as well as adverse cascading effects in the markets and the financials sector generally. Companies in the financials sector may also be adversely affected by increases in interest rates and loan losses, decreases in the availability of money or asset valuations, credit rating downgrades, adverse public perception and adverse conditions in other related markets. Insurance companies, in particular, may be subject to severe price competition and/or rate regulation, which may have an adverse impact on their profitability. The financials sector is particularly sensitive to fluctuations in interest rates. The financials sector is also a target for cyberattacks. Cybersecurity incidents and technology malfunctions and failures have become increasingly frequent and have caused significant losses to companies in this sector, which may negatively impact the Fund. The extent to which the Fund may invest in a company that engages in securities-related activities or banking is limited by applicable law.

 

INDIRECT INVESTMENT RISK. Robinhood Markets, Inc. is not affiliated with the Trust, the Fund, the Adviser, the Sub-Adviser or any affiliates thereof and is not involved with this offering in any way, and has no obligation to consider the Fund in taking any corporate actions that might affect the value of the Fund. The Trust, the Fund, the Adviser, the Sub-Adviser or any affiliate are not responsible for the performance of HOOD and make no representation as to the performance of HOOD. Investing in the Fund is not equivalent to investing in HOOD. Fund shareholders will not have voting rights or rights to receive dividends or other distributions or any other rights with respect to HOOD.

 

LARGE CAPITALIZATION COMPANIES RISK. Large capitalization companies may be less able than smaller capitalization companies to adapt to changing market conditions. Large capitalization companies may be more mature and subject to more limited growth potential compared with smaller capitalization companies. During different market cycles, the performance of large capitalization companies has trailed the overall performance of the broader securities markets.

 

UNITED STATES RISK. Certain changes in the U.S. economy, such as when the U.S. economy weakens or when its financial markets decline, may have an adverse effect on the securities to which the Fund has exposure.

NON-DIVERSIFICATION RISK. As a “non-diversified” fund, the Fund may hold a smaller number of portfolio securities than many other funds. To the extent the Fund invests in a relatively small number of issuers, a decline in the market value of a particular security held by the Fund may affect its value more than if it invested in a larger number of issuers. The value of the Fund Shares may be more volatile than the values of shares of more diversified funds.

Roundhill NFLX WeeklyPay™ ETF | MARKET RISK  
Prospectus [Line Items]  
Risk [Text Block]

MARKET RISK. Market risk is the risk that a particular investment, or Fund Shares in general, may fall in value. Securities are subject to market fluctuations caused by real or perceived adverse economic, political, and regulatory factors or market developments, changes in interest rates, disruptions to trade, impositions of tariffs and perceived trends in securities prices. Fund Shares could decline in value or underperform other investments. In addition, local, regional or global events such as war, acts of terrorism, market manipulation, government defaults, government shutdowns, regulatory actions, political changes, diplomatic developments, the imposition of sanctions and other similar measures, spread of infectious diseases or other public health issues, recessions, natural disasters, or other events could have a significant negative impact on the Fund and its investments. Any of such circumstances could have a materially negative impact on the value of Fund Shares, the liquidity of an investment, and may result in increased market volatility. During any such events, Fund Shares may trade at increased premiums or discounts to their net asset value, the bid/ask spread on Fund Shares may widen and the returns on investment may fluctuate.

Roundhill NFLX WeeklyPay™ ETF | LIQUIDITY RISK  
Prospectus [Line Items]  
Risk [Text Block]

LIQUIDITY RISK. The market for swap agreements that reference NFLX shares may be subject to periods of illiquidity. During such times it may be difficult or impossible to buy or sell a position at the desired price. Market disruptions or volatility can also make it difficult to find a counterparty willing to transact at a reasonable price and sufficient size. Illiquid markets may cause losses, which could be significant. The large size of the positions which the Fund may acquire increases the risk of illiquidity, may make its positions more difficult to liquidate, and may increase the losses incurred while trying to do so. Such large positions also may impact the price of swap agreements on NFLX shares.

Roundhill NFLX WeeklyPay™ ETF | ACTIVE MANAGEMENT RISK  
Prospectus [Line Items]  
Risk [Text Block]

ACTIVE MANAGEMENT RISK. The Fund is actively-managed and its performance reflects investment decisions that the Adviser and/or Sub-Adviser makes for the Fund. Such judgments about the Fund’s investments may prove to be incorrect. If the investments selected and the strategies employed by the Fund fail to produce the intended results, the Fund could underperform as compared to other funds with similar investment objectives and/or strategies, or could have negative returns.

Roundhill NFLX WeeklyPay™ ETF | ACTIVE MARKET RISK  
Prospectus [Line Items]  
Risk [Text Block]

ACTIVE MARKET RISK. Although Fund Shares are listed for trading on the Exchange, there can be no assurance that an active trading market for Fund Shares will develop or be maintained. Fund Shares trade on the Exchange at market prices that may be below, at or above the Fund’s net asset value. Securities, including Fund Shares, are subject to market fluctuations and liquidity constraints that may be caused by such factors as economic, political, or regulatory developments, changes in interest rates, and/or perceived trends in securities prices. Fund Shares could decline in value or underperform other investments.

Roundhill NFLX WeeklyPay™ ETF | ASSET CLASS RISK

CONCENTRATION RISK. The Fund is susceptible to an increased risk of loss, including losses due to adverse events that affect the Fund’s investments more than the market as a whole, to the extent that the Fund’s investments are concentrated in investments that provide exposure to NFLX and the industry to which it is assigned.

Roundhill NFLX WeeklyPay™ ETF | COUNTERPARTY RISK  
Prospectus [Line Items]  
Risk [Text Block]

COUNTERPARTY RISK. Fund transactions involving a counterparty are subject to the risk that the counterparty will not fulfill its obligation to the Fund. Counterparty risk may arise because of the counterparty’s financial condition (i.e., financial difficulties, bankruptcy, or insolvency), market activities and developments, or other reasons, whether foreseen or not. A counterparty’s inability to fulfill its obligation may result in significant financial loss to the Fund. The Fund may be unable to recover its investment from the counterparty or may obtain a limited recovery, and/or recovery may be delayed.

CREDIT RISK. An issuer or other obligated party of a debt security may be unable or unwilling to make dividend, interest and/or principal payments when due. In addition, the value of a debt security may decline because of concerns about the issuer’s ability or unwillingness to make such payments.

Roundhill NFLX WeeklyPay™ ETF | CURRENT MARKET CONDITIONS RISK  
Prospectus [Line Items]  
Risk [Text Block]

CURRENT MARKET CONDITIONS RISK. Current market conditions risk is the risk that a particular investment, or Fund Shares in general, may fall in value due to current market conditions. As a means to fight inflation, which remains at elevated levels, the Federal Reserve and certain foreign central banks have raised interest rates; however, the Federal Reserve has recently lowered interest rates and may continue to do so. U.S. regulators have proposed several changes to market and issuer regulations which would directly impact the Fund, and any regulatory changes could adversely impact the Fund’s ability to achieve its investment strategies or make certain investments. Recent and potential future bank failures could result in disruption to the broader banking industry or markets generally and reduce confidence in financial institutions and the economy as a whole, which may also heighten market volatility and reduce liquidity. Additionally, challenges in commercial real estate markets, including rising interest rates, declining valuations and increasing vacancies, could have a broader impact on financial markets. The ongoing adversarial political climate in the United States, as well as political and diplomatic events both domestic and abroad, have and may continue to have an adverse impact the U.S. regulatory landscape, markets and investor behavior, which could have a negative impact on the Fund’s investments and operations. The change in administration resulting from the 2024 United States national elections could result in significant impacts to international trade relations, tax and immigration policies, and other aspects of the national and international political and financial landscape, which could affect, among other things, inflation and the securities markets generally. Other unexpected political, regulatory and diplomatic events within the U.S. and abroad may affect investor and consumer confidence and may adversely impact financial markets and the broader economy. For example, ongoing armed conflicts between Russia and Ukraine in Europe and among Israel, Iran, Hamas and other militant groups in the Middle East, have caused and could continue to cause significant market disruptions and volatility within the markets in Russia, Europe, the Middle East and the United States. The hostilities and sanctions resulting from those hostilities have and could continue to have a significant impact on certain Fund investments as well as Fund performance and liquidity. The economies of the United States and its trading partners, as well as the financial markets generally, may be adversely impacted by trade disputes, including the imposition of tariffs, and other matters. For example, the United States has imposed trade barriers and restrictions on China. In addition, the Chinese government is engaged in a longstanding dispute with Taiwan, continually threatening an invasion. If the political climate between the United States and China does not improve or continues to deteriorate, if China were to attempt invading Taiwan, or if other geopolitical conflicts develop or worsen, economies, markets and individual securities may be adversely affected, and the value of the Fund’s assets may go down. A public health crisis and the ensuing policies enacted by governments and central banks may cause significant volatility and uncertainty in global financial markets, negatively impacting global growth prospects. As the COVID-19 global pandemic illustrated, such events may affect certain geographic regions, countries, sectors and industries more significantly than others. Advancements in technology may also adversely impact markets and the overall performance of the Fund. For instance, the economy may be significantly impacted by the advanced development and increased regulation of artificial intelligence. Additionally, cyber security breaches of both government and non-government entities could have negative impacts on infrastructure and the ability of such entities, including the Fund, to operate properly. These events, and any other future events, may adversely affect the prices and liquidity of the Fund’s portfolio investments and could result in disruptions in the trading markets.

Roundhill NFLX WeeklyPay™ ETF | CYBERSECURITY RISK  
Prospectus [Line Items]  
Risk [Text Block]

CYBERSECURITY RISK. Failures or breaches of the electronic systems of the Fund, the Fund’s adviser, sub-adviser, distributor and other service providers, market makers, Authorized Participants or the issuers of securities in which the Fund invests have the ability to cause disruptions, negatively impact the Fund’s business operations and/or potentially result in financial losses to the Fund and its shareholders. While the Fund has established business continuity plans and risk management systems seeking to address system breaches or failures, there are inherent limitations in such plans and systems. Furthermore, the Fund cannot control the cybersecurity plans and systems of the Fund’s other service providers, market makers, Authorized Participants or issuers of securities in which the Fund invests.

Roundhill NFLX WeeklyPay™ ETF | DEBT SECURITIES RISK  
Prospectus [Line Items]  
Risk [Text Block]

DEBT SECURITIES RISK. Investments in debt securities subject the holder to the credit risk of the issuer. Credit risk refers to the possibility that the issuer or other obligor of a security will not be able or willing to make payments of interest and principal when due. Generally, the value of debt securities will change inversely with changes in interest rates. To the extent that interest rates rise, certain underlying obligations may be paid off substantially slower than originally anticipated and the value of those securities may fall sharply. During periods of falling interest rates, the income received by the Fund may decline. If the principal on a debt security is prepaid before expected, the prepayments of principal may have to be reinvested in obligations paying interest at lower rates. Debt securities generally do not trade on a securities exchange making them generally less liquid and more difficult to value than common stock.

Roundhill NFLX WeeklyPay™ ETF | DERIVATIVES RISK  
Prospectus [Line Items]  
Risk [Text Block]

DERIVATIVES RISK. The use of derivative instruments involves risks different from, or possibly greater than, the risks associated with investing directly in securities and other traditional investments. These risks include: (i) the risk that the counterparty to a derivative transaction may not fulfill its contractual obligations; (ii) risk of mispricing or improper valuation; and (iii) the risk that changes in the value of the derivative may not correlate perfectly with the underlying asset. Derivative prices are highly volatile and may fluctuate substantially during a short period of time. Such prices are influenced by numerous factors that affect the markets, including, but not limited to: changing supply and demand relationships; government programs and policies; national and international political and economic events, changes in interest rates, inflation and deflation and changes in supply and demand relationships. Trading derivative instruments involves risks different from, or possibly greater than, the risks associated with investing directly in securities. Derivative contracts ordinarily have leverage inherent in their terms. The use of leverage may cause the Fund to liquidate portfolio positions when it would not be advantageous to do so in order to satisfy its obligations or to meet regulatory or contractual requirements for derivatives. The use of derivatives can magnify potential for gain or loss and, therefore, amplify the effects of market volatility on share price.

Roundhill NFLX WeeklyPay™ ETF | DISTRIBUTION TAX RISK  
Prospectus [Line Items]  
Risk [Text Block]

DISTRIBUTION TAX RISK. The Fund currently expects to make distributions on a weekly basis. Such frequent distributions may expose investors to increased tax liabilities. However, these distributions may exceed the Fund’s income and gains for the Fund’s taxable year. Distributions in excess of the Fund’s current and accumulated earnings and profits will be treated as a return of capital. A return of capital distribution generally will not be taxable but will reduce the shareholder’s cost basis and will result in a higher capital gain or lower capital loss when those Fund Shares on which the distribution was received are sold. Once a Fund shareholder’s cost basis is reduced to zero, further distributions will be treated as capital gain if the Fund shareholder holds Fund Shares as capital assets. Additionally, any capital returned through distributions will be distributed after payment of Fund fees and expenses. Because a portion of the Fund’s distributions may consist of return of capital, the Fund may not be an appropriate investment for investors who do not want their principal investment in the Fund to decrease over time or who do not wish to receive return of capital in a given period. In the event that a shareholder purchases Fund Shares shortly before a distribution by the Fund, the entire distribution may be taxable to the shareholder even though a portion of the distribution effectively represents a return of the purchase price.

Roundhill NFLX WeeklyPay™ ETF | ETF RISK  
Prospectus [Line Items]  
Risk [Text Block]

ETF RISK. The Fund may invest in ETFs. The value of an ETF held by the Fund will fluctuate over time based on fluctuations in the values of the assets held by the ETF, which may be affected by changes in general economic conditions, expectations for future growth and profits, interest rates and the supply and demand for those assets. When the Fund invests in an ETF, it will bear a proportionate share of the ETF’s expenses. Brokerage, tax and other expenses may negatively impact the performance of the ETF and, in turn, the value of the Fund Shares. An ETF that tracks an index may not exactly match the performance of the index due to cash drag, differences between the portfolio of the ETF and the components of the index, expenses and other factors.

Roundhill NFLX WeeklyPay™ ETF | INFLATION RISK  
Prospectus [Line Items]  
Risk [Text Block]

INFLATION RISK. Inflation risk is the risk that the value of assets or income from investments will be less in the future as inflation decreases the value of money. As inflation increases, the present value of the Fund’s assets and distributions may decline. This risk is more prevalent with respect to fixed income securities held by the Fund.

Roundhill NFLX WeeklyPay™ ETF | Interest Rate Risk [Member]  
Prospectus [Line Items]  
Risk [Text Block]

INTEREST RATE RISK. Interest rate risk is the risk that the value of the debt securities in the Fund’s portfolio will decline because of rising market interest rates. Interest rate risk is generally lower for shorter term debt securities and higher for longer-term debt securities. Duration is a reasonably accurate measure of a debt security’s price sensitivity to changes in interest rates and a common measure of interest rate risk. Duration measures a debt security’s expected life on a present value basis, taking into account the debt security’s yield, interest payments and final maturity. In general, duration represents the expected percentage change in the value of a security for an immediate 1% change in interest rates. For example, the price of a debt security with a three-year duration would be expected to drop by approximately 3% in response to a 1% increase in interest rates. Therefore, prices of debt securities with shorter durations tend to be less sensitive to interest rate changes than debt securities with longer durations. As the value of a debt security changes over time, so will its duration.

Roundhill NFLX WeeklyPay™ ETF | LEGISLATION AND LITIGATION RISK  
Prospectus [Line Items]  
Risk [Text Block]

LEGISLATION AND LITIGATION RISK. Legislation or litigation that affects the value of assets or securities held by the Fund may reduce the value of the Fund. From time to time, various legislative initiatives are proposed that may have a negative impact on certain assets or securities in which the Fund invests. In addition, litigation regarding any of the assets or securities owned by the Fund may negatively impact the value of the Shares. Such legislation or litigation may cause the Fund to lose value or may result in higher portfolio turnover if the Adviser determines to sell such a holding.

Roundhill NFLX WeeklyPay™ ETF | LEVERAGE RISK  
Prospectus [Line Items]  
Risk [Text Block]

LEVERAGE RISK. The Fund obtains investment exposure in excess of its net assets by utilizing leverage and may lose more money in market conditions that are adverse to its investment objectives than a fund that does not utilize leverage. An investment in the Fund is exposed to the risk that a decline in the weekly performance of shares of NFLX will be magnified. This means that an investment in the Fund will be reduced by an amount equal to 1.2% for every 1% weekly decline in the market value of the NFLX shares, not including the costs of financing leverage and other operating expenses, which would further reduce its value. The Fund could theoretically lose an amount greater than its net assets in the event the market value of NFLX shares decline more than 83.33% over a calendar week. Leverage will also have the effect of magnifying any differences in the Fund’s correlation with NFLX shares.

Roundhill NFLX WeeklyPay™ ETF | MONEY MARKET INSTRUMENTS RISK  
Prospectus [Line Items]  
Risk [Text Block]

MONEY MARKET INSTRUMENTS RISK. The value of money market instruments may be affected by changing interest rates and by changes in the credit ratings of the investments. If a significant amount of the Fund’s assets are invested in money market instruments, it will be more difficult for the Fund to achieve its investment objectives. An investment in a money market fund is not insured or guaranteed by the FDIC or any other government agency. It is possible to lose money by investing in a money market fund.

Roundhill NFLX WeeklyPay™ ETF | OPERATIONAL RISK  
Prospectus [Line Items]  
Risk [Text Block]

OPERATIONAL RISK. The Fund is subject to risks arising from various operational factors, including, but not limited to, human error, processing and communication errors, errors of the Fund’s service providers, counterparties or other third-parties, failed or inadequate processes and technology or systems failures. The Fund relies on third-parties for a range of services, including custody. Any delay or failure relating to engaging or maintaining such service providers may affect the Fund’s ability to meet its investment objectives. Although the Fund and the Adviser seek to reduce these operational risks through controls and procedures, there is no way to completely protect against such risks.

Roundhill NFLX WeeklyPay™ ETF | SPECIAL TAX RISK  
Prospectus [Line Items]  
Risk [Text Block]

SPECIAL TAX RISK. The Fund intends to qualify annually and to elect to be treated as a regulated investment company under the Internal Revenue Code of 1986, as amended (the “Code”). To qualify for the favorable U.S. federal income tax treatment generally accorded to regulated investment companies, the Fund must, among other things, (i) derive in each taxable year at least 90% of its gross income from dividends, interest, payments with respect to securities loans and gains from the sale or other disposition of stock, securities or foreign currencies or other income derived with respect to its business of investing in such stock, securities or currencies, or net income derived from interests in certain publicly traded partnerships; (ii) diversify its holdings so that, at the end of each quarter of the taxable year, (a) at least 50% of the market value of the Fund’s assets is represented by cash and cash items (including receivables), U.S. government securities, the securities of other regulated investment companies and other securities, with such other securities of any one issuer generally limited for the purposes of this calculation to an amount not greater than 5% of the value of the Fund’s total assets and not greater than 10% of the outstanding voting securities of such issuer, and (b) not more than 25% of the value of its total assets is invested in the securities (other than U.S. government securities or the securities of other regulated investment companies) of any one issuer, or two or more issuers which the Fund controls which are engaged in the same, similar or related trades or businesses, or the securities of one or more of certain publicly traded partnerships; and (iii) distribute at least 90% of its investment company taxable income (which includes, among other items, dividends, interest and net short-term capital gains in excess of net long-term capital losses) and at least 90% of its net tax-exempt interest income each taxable year. There are certain exceptions for failure to qualify if the failure is for reasonable cause or is de minimis, and certain corrective action is taken and certain tax payments are made by the Fund.

 

The authority with regard to swaps entered into by regulated investment companies is unclear both as to the qualification under the income test and the identification of the issuer under the diversification test. The Fund intends to take the position that because the swaps held by the Fund reference securities that the income on the swaps are “other income” from the Fund’s business of investing in stocks and securities. In addition, the Fund intends to manage its investments in the swaps so that neither the exposure to issuer of the referenced security nor the exposure to any one counterparty of the swaps will exceed 25% of the gross value of the Fund’s portfolio at the end of any quarter.

 

If the Fund were to fail to meet the qualifying income test or asset diversification test and fail to qualify as a RIC, it would be taxed in the same manner as an ordinary corporation, and distributions to its shareholders would not be deductible by the Fund in computing its taxable income, which would adversely affect the Fund’s performance.

Roundhill NFLX WeeklyPay™ ETF | STRUCTURAL ETF RISKS  
Prospectus [Line Items]  
Risk [Text Block]

STRUCTURAL ETF RISKS. The Fund is an ETF. Accordingly, it is subject to certain risks associated with its unique structure.

 

Market Participants Risk. Only an Authorized Participant may engage in creation or redemption transactions directly with the Fund, and none of those Authorized Participants is obligated to engage in creation and/or redemption transactions. The Fund has a limited number of institutions that may act as Authorized Participants on an agency basis (i.e., on behalf of other market participants). To the extent that Authorized Participants exit the business or are unable to proceed with creation or redemption orders with respect to the Fund and no other Authorized Participant is able to step forward to create or redeem, Fund Shares may be more likely to trade at a premium or discount to NAV and possibly face trading halts or delisting. The Fund may also rely on a small number of third-party market makers to provide a market for the purchase and sale of Fund Shares but such market makers are under no obligation to do so. Decisions by Authorized Participants or market makers to reduce their role or step away from these activities in times of market stress could inhibit the effectiveness of the arbitrage process in maintaining the relationship between the underlying values of the Fund’s portfolio securities and the Fund’s market price. Any trading halt or other problem relating to the trading activity of these market makers or any issues disrupting the Authorized Participants’ ability to proceed with creation and/or redemption orders could result in a dramatic change in the spread between the Fund’s net asset value and the price at which Fund Shares are trading on the Exchange, which could result in a decrease in value of Fund Shares. This reduced effectiveness could result in Fund Shares trading at a premium or discount to net asset value and also in greater than normal intraday bid-ask spreads Fund Shares.

 

Cash Transactions Risk. The Fund currently expects to effect a significant portion of its creations and redemptions for cash, rather than in-kind securities. Paying redemption proceeds in cash rather than through in-kind delivery of portfolio securities may require the Fund to dispose of or sell portfolio securities or other assets at an inopportune time to obtain the cash needed to meet redemption orders. This may cause the Fund to sell a security and recognize a capital gain or loss that might not have been incurred if it had made a redemption in-kind. As a result, the Fund may pay out higher or lower annual capital gains distributions than ETFs that redeem in-kind. The use of cash creations and redemptions may also cause the Fund’s Shares to trade in the market at greater bid-ask spreads or greater premiums or discounts to the Fund’s NAV. Furthermore, the Fund may not be able to execute cash transactions for creation and redemption purposes at the same price used to determine the Fund’s NAV. To the extent that the maximum additional charge for creation or redemption transactions is insufficient to cover the execution shortfall, the Fund’s performance could be negatively impacted.

 

Costs of Buying and Selling Fund Shares. Due to the costs of buying or selling Fund Shares, including brokerage commissions imposed by brokers and bid/ask spreads, frequent trading of Fund Shares may significantly reduce investment results and an investment in Fund Shares may not be advisable for investors who anticipate regularly making small investments.

 

Premium/Discount Risk. As with all ETFs, Fund Shares may be bought and sold in the secondary market at market prices. The trading prices of Fund Shares in the secondary market may differ from the Fund’s daily net asset value per share and there may be times when the market price of the shares is more than the net asset value per share (premium) or less than the net asset value per share (discount). If a shareholder purchases Fund Shares at a time when the market price is at a premium to the net asset value or sells Fund Shares at a time when the market price is at a discount to the net asset value, the shareholder may pay more for, or receive less than, the underlying value of the Fund Shares, respectively. This risk is heightened in times of market volatility or periods of steep market declines.

 

Trading Risks. Although Fund Shares are listed for trading on the Exchange and may be traded on U.S. exchanges other than the Exchange, there can be no assurance that Fund Shares will trade with any volume, or at all, on any stock exchange. In stressed market conditions, the liquidity of Fund Shares may begin to mirror the liquidity of the Fund’s underlying portfolio holdings, which can be significantly less liquid than Fund Shares. Trading in Fund Shares on the Exchange may be halted due to market conditions or for reasons that, in the view of the Exchange, make trading in Fund Shares inadvisable. In addition, trading in Fund Shares on the Exchange is subject to trading halts caused by extraordinary market volatility pursuant to the Exchange’s “circuit breaker” rules. There can be no assurance that the requirements of the Exchange necessary to maintain the listing of the Fund will continue to be met or will remain unchanged.

Roundhill NFLX WeeklyPay™ ETF | U.S. GOVERNMENT SECURITIES RISK  
Prospectus [Line Items]  
Risk [Text Block]

U.S. GOVERNMENT SECURITIES RISK. U.S. government securities are subject to interest rate risk but generally do not involve the credit risks associated with investments in other types of debt securities. As a result, the yields available from U.S. government securities are generally lower than the yields available from other debt securities. U.S. government securities are guaranteed only as to the timely payment of interest and the payment of principal when held to maturity.

Roundhill NFLX WeeklyPay™ ETF | VALUATION RISK  
Prospectus [Line Items]  
Risk [Text Block]

VALUATION RISK. The Fund may hold securities or other assets that may be valued on the basis of factors other than market quotations. This may occur because the asset or security does not trade on a centralized exchange, or in times of market turmoil or reduced liquidity. There are multiple methods that can be used to value a portfolio holding when market quotations are not readily available. The value established for any portfolio holding at a point in time might differ from what would be produced using a different methodology or if it had been priced using market quotations. Portfolio holdings that are valued using techniques other than market quotations, including “fair valued” assets or securities, may be subject to greater fluctuation in their valuations from one day to the next than if market quotations were used. In addition, there is no assurance that the Fund could sell or close out a portfolio position for the value established for it at any time, and it is possible that the Fund would incur a loss because a portfolio position is sold or closed out at a discount to the valuation established by the Fund at that time. The Fund’s ability to value investments may be impacted by technological issues or errors by pricing services or other third-party service providers.

Roundhill NFLX WeeklyPay™ ETF | EQUITY SECURITIES RISK  
Prospectus [Line Items]  
Risk [Text Block]

EQUITY SECURITIES RISK. Equity securities are subject to changes in value, and their values may be more volatile than those of other asset classes. Equity securities prices fluctuate for several reasons, including changes in investors’ perceptions of the financial condition of an issuer or the general condition of the relevant equity market, such as market volatility, or when political or economic events affecting an issuer occur. Common stock prices may be particularly sensitive to rising interest rates, as the cost of capital rises and borrowing costs increase. Common stocks generally subject their holders to more risks than preferred stocks and debt securities because common stockholders’ claims are subordinated to those of holders of preferred stocks and debt securities upon the bankruptcy of the issuer.

Roundhill NFLX WeeklyPay™ ETF | SWAP AGREEMENTS RISK  
Prospectus [Line Items]  
Risk [Text Block]

SWAP AGREEMENTS RISK. The Fund will utilize swap agreements to derive its exposure to shares of NFLX. Swap agreements may involve greater risks than direct investment in securities as they may be leveraged and are subject to credit risk, counterparty risk and valuation risk. A swap agreement could result in losses if the underlying reference or asset does not perform as anticipated. In addition, many swaps trade over-the-counter and may be considered illiquid. It may not be possible for the Fund to liquidate a swap position at an advantageous time or price, which may result in significant losses.

Roundhill NFLX WeeklyPay™ ETF | REGULATED INVESTMENT COMPANY TAX RISKS  
Prospectus [Line Items]  
Risk [Text Block]

REGULATED INVESTMENT COMPANY TAX RISKS. The Fund intends to qualify annually and to elect to be treated as a regulated investment company under the Internal Revenue Code of 1986, as amended (the “Code”). To qualify for the favorable U.S. federal income tax treatment generally accorded to regulated investment companies, the Fund must, among other things, (i) derive in each taxable year at least 90% of its gross income from dividends, interest, payments with respect to securities loans and gains from the sale or other disposition of stock, securities or foreign currencies or other income derived with respect to its business of investing in such stock, securities or currencies, or net income derived from interests in certain publicly traded partnerships; (ii) diversify its holdings so that, at the end of each quarter of the taxable year, (a) at least 50% of the market value of the Fund’s assets is represented by cash and cash items (including receivables), U.S. government securities, the securities of other regulated investment companies and other securities, with such other securities of any one issuer generally limited for the purposes of this calculation to an amount not greater than 5% of the value of the Fund’s total assets and not greater than 10% of the outstanding voting securities of such issuer, and (b) not more than 25% of the value of its total assets is invested in the securities (other than U.S. government securities or the securities of other regulated investment companies) of any one issuer, or two or more issuers which the Fund controls which are engaged in the same, similar or related trades or businesses, or the securities of one or more of certain publicly traded partnerships; and (iii) distribute at least 90% of its investment company taxable income (which includes, among other items, dividends, interest and net short-term capital gains in excess of net long-term capital losses) and at least 90% of its net tax-exempt interest income each taxable year. There are certain exceptions for failure to qualify if the failure is for reasonable cause or is de minimis, and certain corrective action is taken and certain tax payments are made by the Fund.

 

If the Fund were to fail to meet the qualifying income test or asset diversification test and fail to qualify as a RIC, it would be taxed in the same manner as an ordinary corporation, and distributions to its shareholders would not be deductible by the Fund in computing its taxable income, which would adversely affect the Fund’s performance.

Roundhill NFLX WeeklyPay™ ETF | LARGE SHAREHOLDER RISK  
Prospectus [Line Items]  
Risk [Text Block]

LARGE SHAREHOLDER RISK. Certain shareholders, including affiliated funds advised by the Adviser, may from time to time own a significant portion of the Fund’s shares. In addition, a third-party investor, the Adviser or an affiliate of the Adviser (“Affiliate”), an authorized participant, a market maker, or another entity may invest in the Fund and hold its investment for a limited period solely to facilitate the commencement of the Fund or to help the Fund achieve a specified size or scale. There can be no assurance that any large shareholder will not redeem its investment, that the size of the Fund will be maintained at such levels, or that the Fund will continue to meet applicable listing requirements. Redemptions by large shareholders could have a significant negative impact on the Fund. In addition, transactions by large shareholders may account for a large percentage of the trading volume on the Fund’s listing exchange and may, therefore, have a material upward or downward effect on the market price of the shares.

 

To the extent that a significant percentage of the Fund’s shares are owned or controlled by a small number of account shareholders (or a single account shareholder), including funds or accounts over which the Adviser or an Affiliate has investment discretion, the Fund is subject to the risk that those shareholders may purchase or redeem Fund shares in significant amounts rapidly or unexpectedly, including as a result of an asset allocation decision made by the Adviser or an Affiliate. This may adversely affect the Fund’s performance if the Adviser is forced to sell portfolio securities or invest cash when it would not otherwise choose to do so. Redemptions of a large number of shares may affect the liquidity of the Fund’s portfolio, increase the Fund’s transaction costs, and accelerate the realization of taxable income and/or gains. In addition, a large redemption could result in the Fund’s current expenses being allocated over a smaller asset base, leading to an increase in the Fund’s gross expense ratio. Large purchases of the Fund’s shares may also adversely affect the Fund’s performance to the extent that the Fund is delayed in investing new cash or otherwise maintains a larger cash position than it ordinarily would, particularly if the Fund accepts cash for an order for the purchase of creation units of the Fund’s shares.

Roundhill NFLX WeeklyPay™ ETF | NFLX INVESTING RISKS  
Prospectus [Line Items]  
Risk [Text Block]

NFLX INVESTING RISKS. The Fund will have significant exposure to NFLX through its investments in swap agreements that utilize NFLX as the reference asset. Accordingly, the Fund will subject to the risks of NFLX, set forth below.

 

NFLX ISSUER-SPECIFIC RISKS. Issuer-specific attributes may cause an investment held by the Fund to be more volatile than the market generally. The value of an individual security or particular type of security may be more volatile than the market as a whole and may perform differently from the value of the market as a whole. NFLX faces significant competition from both traditional media companies and digital streaming services. Increased competition could lead to subscriber churn, pricing pressure, and higher content acquisition costs. As NFLX reaches high penetration in key markets, particularly North America and Europe, sustaining subscriber growth may become more difficult. Expansion in emerging markets faces challenges such as lower consumer purchasing power and infrastructure limitations. NFLX’s business model relies on continuous investment in original programming and licensed content. Rising production costs, licensing fees, or underperformance of new content could negatively impact profitability. NFLX’s also success depends on its ability to consistently produce and distribute compelling content that retains and attracts subscribers. A decline in content quality or user engagement could lead to higher cancellation rates. Lastly, NFLX depends on licensing agreements for third-party content. The loss or renegotiation of key licensing deals could reduce the available content library and weaken subscriber appeal. NFLX’s business depends on the reliability of internet service providers, cloud computing infrastructure, and its proprietary recommendation algorithm. Any technical failures, outages, or cyberattacks could disrupt service and impact user retention.

 

INDIRECT INVESTMENT RISK. Netflix, Inc. is not affiliated with the Trust, the Fund, the Adviser, the Sub-Adviser or any affiliates thereof and is not involved with this offering in any way, and has no obligation to consider the Fund in taking any corporate actions that might affect the value of the Fund. The Trust, the Fund, the Adviser, the Sub-Adviser or any affiliate are not responsible for the performance of NFLX and make no representation as to the performance of NFLX. Investing in the Fund is not equivalent to investing in NFLX. Fund shareholders will not have voting rights or rights to receive dividends or other distributions or any other rights with respect to NFLX.

 

COMMUNICATION SERVICES COMPANIES RISK. Companies in the communication services sector may be affected by industry competition, substantial capital requirements, government regulation, and obsolescence of communications products and services due to technological advancement. Fluctuating domestic and international demand, shifting demographics and often unpredictable changes in consumer tastes can drastically affect a communication services company’s profitability. In addition, while all companies may be susceptible to network security breaches, certain companies in the communication services sector may be particular targets of hacking and potential theft of proprietary or consumer information or disruptions in service, which could have a material adverse effect on their businesses.

 

The communication services sector of a country’s economy is often subject to extensive government regulation. The costs of complying with governmental regulations, delays or failure to receive required regulatory approvals, or the enactment of new regulatory requirements may negatively affect the business of communications companies. Government actions around the world, specifically in the area of pre-marketing clearance of products and prices, can be arbitrary and unpredictable. The communications services industry can also be significantly affected by intense competition for market share, including competition with alternative technologies such as wireless communications, product compatibility and standardization, consumer preferences, rapid product obsolescence, research and development of new products, lack of standardization or compatibility with existing technologies, and a dependency on patent and copyright protections. Companies in the communication services sector may encounter distressed cash flows due to the need to commit substantial capital to meet increasing competition, particularly in developing new products and services using new technology. Technological innovations may make the products and services of certain communications companies obsolete.

 

LARGE CAPITALIZATION COMPANIES RISK. Large capitalization companies may be less able than smaller capitalization companies to adapt to changing market conditions. Large capitalization companies may be more mature and subject to more limited growth potential compared with smaller capitalization companies. During different market cycles, the performance of large capitalization companies has trailed the overall performance of the broader securities markets.

 

MEDIA & ENTERTAINMENT COMPANIES RISK. The media & entertainment industry is influenced by evolving consumer preferences, technological advancements, content production costs, regulatory changes, and macroeconomic factors, all of which could contribute to volatility and potential losses. Media companies that rely on advertising revenue are exposed to economic cycles, as advertisers may reduce spending during economic downturns. The rise of digital ad-blocking tools and privacy regulations could further challenge ad-based business models. For those media & entertainment companies that rely on subscription-based revenue models, subscriber growth and retention depend on pricing strategies, content quality, and competition. A slowdown in new subscriptions or high churn rates could negatively impact revenue. The transition from traditional cable television to digital streaming platforms has disrupted the media landscape. Companies dependent on linear TV advertising or cable subscriptions face ongoing subscriber losses, while streaming services must continuously adapt to evolving consumption habits. Success in the entertainment industry depends on the ability to produce, acquire, and distribute compelling content. High production costs for original content, coupled with uncertainty about audience reception, can create financial risk. Even with significant investment, content success is unpredictable. Underperformance of major films, TV shows, or digital media projects can result in financial losses and damage brand value. Companies that license third-party content may face contract renegotiations, content losses, or increased licensing fees. Conversely, companies reliant on proprietary franchises must protect their intellectual property from piracy and unauthorized distribution.

 

UNITED STATES RISK. Certain changes in the U.S. economy, such as when the U.S. economy weakens or when its financial markets decline, may have an adverse effect on the securities to which the Fund has exposure.

NON-DIVERSIFICATION RISK. As a “non-diversified” fund, the Fund may hold a smaller number of portfolio securities than many other funds. To the extent the Fund invests in a relatively small number of issuers, a decline in the market value of a particular security held by the Fund may affect its value more than if it invested in a larger number of issuers. The value of the Fund Shares may be more volatile than the values of shares of more diversified funds.

Roundhill RDDT WeeklyPay™ ETF | MARKET RISK  
Prospectus [Line Items]  
Risk [Text Block]

MARKET RISK. Market risk is the risk that a particular investment, or Fund Shares in general, may fall in value. Securities are subject to market fluctuations caused by real or perceived adverse economic, political, and regulatory factors or market developments, changes in interest rates, disruptions to trade, impositions of tariffs and perceived trends in securities prices. Fund Shares could decline in value or underperform other investments. In addition, local, regional or global events such as war, acts of terrorism, market manipulation, government defaults, government shutdowns, regulatory actions, political changes, diplomatic developments, the imposition of sanctions and other similar measures, spread of infectious diseases or other public health issues, recessions, natural disasters, or other events could have a significant negative impact on the Fund and its investments. Any of such circumstances could have a materially negative impact on the value of Fund Shares, the liquidity of an investment, and may result in increased market volatility. During any such events, Fund Shares may trade at increased premiums or discounts to their net asset value, the bid/ask spread on Fund Shares may widen and the returns on investment may fluctuate.

Roundhill RDDT WeeklyPay™ ETF | LIQUIDITY RISK  
Prospectus [Line Items]  
Risk [Text Block]

LIQUIDITY RISK. The market for swap agreements that reference RDDT shares may be subject to periods of illiquidity. During such times it may be difficult or impossible to buy or sell a position at the desired price. Market disruptions or volatility can also make it difficult to find a counterparty willing to transact at a reasonable price and sufficient size. Illiquid markets may cause losses, which could be significant. The large size of the positions which the Fund may acquire increases the risk of illiquidity, may make its positions more difficult to liquidate, and may increase the losses incurred while trying to do so. Such large positions also may impact the price of swap agreements on RDDT shares.

Roundhill RDDT WeeklyPay™ ETF | ACTIVE MANAGEMENT RISK  
Prospectus [Line Items]  
Risk [Text Block]

ACTIVE MANAGEMENT RISK. The Fund is actively-managed and its performance reflects investment decisions that the Adviser and/or Sub-Adviser makes for the Fund. Such judgments about the Fund’s investments may prove to be incorrect. If the investments selected and the strategies employed by the Fund fail to produce the intended results, the Fund could underperform as compared to other funds with similar investment objectives and/or strategies, or could have negative returns.

Roundhill RDDT WeeklyPay™ ETF | ACTIVE MARKET RISK  
Prospectus [Line Items]  
Risk [Text Block]

ACTIVE MARKET RISK. Although Fund Shares are listed for trading on the Exchange, there can be no assurance that an active trading market for Fund Shares will develop or be maintained. Fund Shares trade on the Exchange at market prices that may be below, at or above the Fund’s net asset value. Securities, including Fund Shares, are subject to market fluctuations and liquidity constraints that may be caused by such factors as economic, political, or regulatory developments, changes in interest rates, and/or perceived trends in securities prices. Fund Shares could decline in value or underperform other investments.

CONCENTRATION RISK. The Fund is susceptible to an increased risk of loss, including losses due to adverse events that affect the Fund’s investments more than the market as a whole, to the extent that the Fund’s investments are concentrated in investments that provide exposure to RDDT and the industry to which it is assigned.

Roundhill RDDT WeeklyPay™ ETF | COUNTERPARTY RISK  
Prospectus [Line Items]  
Risk [Text Block]

COUNTERPARTY RISK. Fund transactions involving a counterparty are subject to the risk that the counterparty will not fulfill its obligation to the Fund. Counterparty risk may arise because of the counterparty’s financial condition (i.e., financial difficulties, bankruptcy, or insolvency), market activities and developments, or other reasons, whether foreseen or not. A counterparty’s inability to fulfill its obligation may result in significant financial loss to the Fund. The Fund may be unable to recover its investment from the counterparty or may obtain a limited recovery, and/or recovery may be delayed.

CREDIT RISK. An issuer or other obligated party of a debt security may be unable or unwilling to make dividend, interest and/or principal payments when due. In addition, the value of a debt security may decline because of concerns about the issuer’s ability or unwillingness to make such payments.

Roundhill RDDT WeeklyPay™ ETF | CURRENT MARKET CONDITIONS RISK  
Prospectus [Line Items]  
Risk [Text Block]

CURRENT MARKET CONDITIONS RISK. Current market conditions risk is the risk that a particular investment, or Fund Shares in general, may fall in value due to current market conditions. As a means to fight inflation, which remains at elevated levels, the Federal Reserve and certain foreign central banks have raised interest rates; however, the Federal Reserve has recently lowered interest rates and may continue to do so. U.S. regulators have proposed several changes to market and issuer regulations which would directly impact the Fund, and any regulatory changes could adversely impact the Fund’s ability to achieve its investment strategies or make certain investments. Recent and potential future bank failures could result in disruption to the broader banking industry or markets generally and reduce confidence in financial institutions and the economy as a whole, which may also heighten market volatility and reduce liquidity. Additionally, challenges in commercial real estate markets, including rising interest rates, declining valuations and increasing vacancies, could have a broader impact on financial markets. The ongoing adversarial political climate in the United States, as well as political and diplomatic events both domestic and abroad, have and may continue to have an adverse impact the U.S. regulatory landscape, markets and investor behavior, which could have a negative impact on the Fund’s investments and operations. The change in administration resulting from the 2024 United States national elections could result in significant impacts to international trade relations, tax and immigration policies, and other aspects of the national and international political and financial landscape, which could affect, among other things, inflation and the securities markets generally. Other unexpected political, regulatory and diplomatic events within the U.S. and abroad may affect investor and consumer confidence and may adversely impact financial markets and the broader economy. For example, ongoing armed conflicts between Russia and Ukraine in Europe and among Israel, Iran, Hamas and other militant groups in the Middle East, have caused and could continue to cause significant market disruptions and volatility within the markets in Russia, Europe, the Middle East and the United States. The hostilities and sanctions resulting from those hostilities have and could continue to have a significant impact on certain Fund investments as well as Fund performance and liquidity. The economies of the United States and its trading partners, as well as the financial markets generally, may be adversely impacted by trade disputes, including the imposition of tariffs, and other matters. For example, the United States has imposed trade barriers and restrictions on China. In addition, the Chinese government is engaged in a longstanding dispute with Taiwan, continually threatening an invasion. If the political climate between the United States and China does not improve or continues to deteriorate, if China were to attempt invading Taiwan, or if other geopolitical conflicts develop or worsen, economies, markets and individual securities may be adversely affected, and the value of the Fund’s assets may go down. A public health crisis and the ensuing policies enacted by governments and central banks may cause significant volatility and uncertainty in global financial markets, negatively impacting global growth prospects. As the COVID-19 global pandemic illustrated, such events may affect certain geographic regions, countries, sectors and industries more significantly than others. Advancements in technology may also adversely impact markets and the overall performance of the Fund. For instance, the economy may be significantly impacted by the advanced development and increased regulation of artificial intelligence. Additionally, cyber security breaches of both government and non-government entities could have negative impacts on infrastructure and the ability of such entities, including the Fund, to operate properly. These events, and any other future events, may adversely affect the prices and liquidity of the Fund’s portfolio investments and could result in disruptions in the trading markets.

Roundhill RDDT WeeklyPay™ ETF | CYBERSECURITY RISK  
Prospectus [Line Items]  
Risk [Text Block]

CYBERSECURITY RISK. Failures or breaches of the electronic systems of the Fund, the Fund’s adviser, sub-adviser, distributor and other service providers, market makers, Authorized Participants or the issuers of securities in which the Fund invests have the ability to cause disruptions, negatively impact the Fund’s business operations and/or potentially result in financial losses to the Fund and its shareholders. While the Fund has established business continuity plans and risk management systems seeking to address system breaches or failures, there are inherent limitations in such plans and systems. Furthermore, the Fund cannot control the cybersecurity plans and systems of the Fund’s other service providers, market makers, Authorized Participants or issuers of securities in which the Fund invests.

Roundhill RDDT WeeklyPay™ ETF | DEBT SECURITIES RISK  
Prospectus [Line Items]  
Risk [Text Block]

DEBT SECURITIES RISK. Investments in debt securities subject the holder to the credit risk of the issuer. Credit risk refers to the possibility that the issuer or other obligor of a security will not be able or willing to make payments of interest and principal when due. Generally, the value of debt securities will change inversely with changes in interest rates. To the extent that interest rates rise, certain underlying obligations may be paid off substantially slower than originally anticipated and the value of those securities may fall sharply. During periods of falling interest rates, the income received by the Fund may decline. If the principal on a debt security is prepaid before expected, the prepayments of principal may have to be reinvested in obligations paying interest at lower rates. Debt securities generally do not trade on a securities exchange making them generally less liquid and more difficult to value than common stock.

Roundhill RDDT WeeklyPay™ ETF | DERIVATIVES RISK  
Prospectus [Line Items]  
Risk [Text Block]

DERIVATIVES RISK. The use of derivative instruments involves risks different from, or possibly greater than, the risks associated with investing directly in securities and other traditional investments. These risks include: (i) the risk that the counterparty to a derivative transaction may not fulfill its contractual obligations; (ii) risk of mispricing or improper valuation; and (iii) the risk that changes in the value of the derivative may not correlate perfectly with the underlying asset. Derivative prices are highly volatile and may fluctuate substantially during a short period of time. Such prices are influenced by numerous factors that affect the markets, including, but not limited to: changing supply and demand relationships; government programs and policies; national and international political and economic events, changes in interest rates, inflation and deflation and changes in supply and demand relationships. Trading derivative instruments involves risks different from, or possibly greater than, the risks associated with investing directly in securities. Derivative contracts ordinarily have leverage inherent in their terms. The use of leverage may cause the Fund to liquidate portfolio positions when it would not be advantageous to do so in order to satisfy its obligations or to meet regulatory or contractual requirements for derivatives. The use of derivatives can magnify potential for gain or loss and, therefore, amplify the effects of market volatility on share price.

Roundhill RDDT WeeklyPay™ ETF | DISTRIBUTION TAX RISK  
Prospectus [Line Items]  
Risk [Text Block]

DISTRIBUTION TAX RISK. The Fund currently expects to make distributions on a weekly basis. Such frequent distributions may expose investors to increased tax liabilities. However, these distributions may exceed the Fund’s income and gains for the Fund’s taxable year. Distributions in excess of the Fund’s current and accumulated earnings and profits will be treated as a return of capital. A return of capital distribution generally will not be taxable but will reduce the shareholder’s cost basis and will result in a higher capital gain or lower capital loss when those Fund Shares on which the distribution was received are sold. Once a Fund shareholder’s cost basis is reduced to zero, further distributions will be treated as capital gain if the Fund shareholder holds Fund Shares as capital assets. Additionally, any capital returned through distributions will be distributed after payment of Fund fees and expenses. Because a portion of the Fund’s distributions may consist of return of capital, the Fund may not be an appropriate investment for investors who do not want their principal investment in the Fund to decrease over time or who do not wish to receive return of capital in a given period. In the event that a shareholder purchases Fund Shares shortly before a distribution by the Fund, the entire distribution may be taxable to the shareholder even though a portion of the distribution effectively represents a return of the purchase price.

Roundhill RDDT WeeklyPay™ ETF | ETF RISK  
Prospectus [Line Items]  
Risk [Text Block]

ETF RISK. The Fund may invest in ETFs. The value of an ETF held by the Fund will fluctuate over time based on fluctuations in the values of the assets held by the ETF, which may be affected by changes in general economic conditions, expectations for future growth and profits, interest rates and the supply and demand for those assets. When the Fund invests in an ETF, it will bear a proportionate share of the ETF’s expenses. Brokerage, tax and other expenses may negatively impact the performance of the ETF and, in turn, the value of the Fund Shares. An ETF that tracks an index may not exactly match the performance of the index due to cash drag, differences between the portfolio of the ETF and the components of the index, expenses and other factors.

Roundhill RDDT WeeklyPay™ ETF | INFLATION RISK  
Prospectus [Line Items]  
Risk [Text Block]

INFLATION RISK. Inflation risk is the risk that the value of assets or income from investments will be less in the future as inflation decreases the value of money. As inflation increases, the present value of the Fund’s assets and distributions may decline. This risk is more prevalent with respect to fixed income securities held by the Fund.

Roundhill RDDT WeeklyPay™ ETF | Interest Rate Risk [Member]  
Prospectus [Line Items]  
Risk [Text Block]

INTEREST RATE RISK. Interest rate risk is the risk that the value of the debt securities in the Fund’s portfolio will decline because of rising market interest rates. Interest rate risk is generally lower for shorter term debt securities and higher for longer-term debt securities. Duration is a reasonably accurate measure of a debt security’s price sensitivity to changes in interest rates and a common measure of interest rate risk. Duration measures a debt security’s expected life on a present value basis, taking into account the debt security’s yield, interest payments and final maturity. In general, duration represents the expected percentage change in the value of a security for an immediate 1% change in interest rates. For example, the price of a debt security with a three-year duration would be expected to drop by approximately 3% in response to a 1% increase in interest rates. Therefore, prices of debt securities with shorter durations tend to be less sensitive to interest rate changes than debt securities with longer durations. As the value of a debt security changes over time, so will its duration.

Roundhill RDDT WeeklyPay™ ETF | LEGISLATION AND LITIGATION RISK  
Prospectus [Line Items]  
Risk [Text Block]

LEGISLATION AND LITIGATION RISK. Legislation or litigation that affects the value of assets or securities held by the Fund may reduce the value of the Fund. From time to time, various legislative initiatives are proposed that may have a negative impact on certain assets or securities in which the Fund invests. In addition, litigation regarding any of the assets or securities owned by the Fund may negatively impact the value of the Shares. Such legislation or litigation may cause the Fund to lose value or may result in higher portfolio turnover if the Adviser determines to sell such a holding.

Roundhill RDDT WeeklyPay™ ETF | LEVERAGE RISK  
Prospectus [Line Items]  
Risk [Text Block]

LEVERAGE RISK. The Fund obtains investment exposure in excess of its net assets by utilizing leverage and may lose more money in market conditions that are adverse to its investment objectives than a fund that does not utilize leverage. An investment in the Fund is exposed to the risk that a decline in the weekly performance of shares of RDDT will be magnified. This means that an investment in the Fund will be reduced by an amount equal to 1.2% for every 1% weekly decline in the market value of the RDDT shares, not including the costs of financing leverage and other operating expenses, which would further reduce its value. The Fund could theoretically lose an amount greater than its net assets in the event the market value of RDDT shares decline more than 83.33% over a calendar week. Leverage will also have the effect of magnifying any differences in the Fund’s correlation with RDDT shares.

Roundhill RDDT WeeklyPay™ ETF | MONEY MARKET INSTRUMENTS RISK  
Prospectus [Line Items]  
Risk [Text Block]

MONEY MARKET INSTRUMENTS RISK. The value of money market instruments may be affected by changing interest rates and by changes in the credit ratings of the investments. If a significant amount of the Fund’s assets are invested in money market instruments, it will be more difficult for the Fund to achieve its investment objectives. An investment in a money market fund is not insured or guaranteed by the FDIC or any other government agency. It is possible to lose money by investing in a money market fund.

Roundhill RDDT WeeklyPay™ ETF | OPERATIONAL RISK  
Prospectus [Line Items]  
Risk [Text Block]

OPERATIONAL RISK. The Fund is subject to risks arising from various operational factors, including, but not limited to, human error, processing and communication errors, errors of the Fund’s service providers, counterparties or other third-parties, failed or inadequate processes and technology or systems failures. The Fund relies on third-parties for a range of services, including custody. Any delay or failure relating to engaging or maintaining such service providers may affect the Fund’s ability to meet its investment objectives. Although the Fund and the Adviser seek to reduce these operational risks through controls and procedures, there is no way to completely protect against such risks.

Roundhill RDDT WeeklyPay™ ETF | SPECIAL TAX RISK

SPECIAL TAX RISK. The Fund intends to qualify annually and to elect to be treated as a regulated investment company under the Internal Revenue Code of 1986, as amended (the “Code”). To qualify for the favorable U.S. federal income tax treatment generally accorded to regulated investment companies, the Fund must, among other things, (i) derive in each taxable year at least 90% of its gross income from dividends, interest, payments with respect to securities loans and gains from the sale or other disposition of stock, securities or foreign currencies or other income derived with respect to its business of investing in such stock, securities or currencies, or net income derived from interests in certain publicly traded partnerships; (ii) diversify its holdings so that, at the end of each quarter of the taxable year, (a) at least 50% of the market value of the Fund’s assets is represented by cash and cash items (including receivables), U.S. government securities, the securities of other regulated investment companies and other securities, with such other securities of any one issuer generally limited for the purposes of this calculation to an amount not greater than 5% of the value of the Fund’s total assets and not greater than 10% of the outstanding voting securities of such issuer, and (b) not more than 25% of the value of its total assets is invested in the securities (other than U.S. government securities or the securities of other regulated investment companies) of any one issuer, or two or more issuers which the Fund controls which are engaged in the same, similar or related trades or businesses, or the securities of one or more of certain publicly traded partnerships; and (iii) distribute at least 90% of its investment company taxable income (which includes, among other items, dividends, interest and net short-term capital gains in excess of net long-term capital losses) and at least 90% of its net tax-exempt interest income each taxable year. There are certain exceptions for failure to qualify if the failure is for reasonable cause or is de minimis, and certain corrective action is taken and certain tax payments are made by the Fund.

 

The authority with regard to swaps entered into by regulated investment companies is unclear both as to the qualification under the income test and the identification of the issuer under the diversification test. The Fund intends to take the position that because the swaps held by the Fund reference securities that the income on the swaps are “other income” from the Fund’s business of investing in stocks and securities. In addition, the Fund intends to manage its investments in the swaps so that neither the exposure to issuer of the referenced security nor the exposure to any one counterparty of the swaps will exceed 25% of the gross value of the Fund’s portfolio at the end of any quarter.

 

If the Fund were to fail to meet the qualifying income test or asset diversification test and fail to qualify as a RIC, it would be taxed in the same manner as an ordinary corporation, and distributions to its shareholders would not be deductible by the Fund in computing its taxable income, which would adversely affect the Fund’s performance.

Roundhill RDDT WeeklyPay™ ETF | STRUCTURAL ETF RISKS  
Prospectus [Line Items]  
Risk [Text Block]

STRUCTURAL ETF RISKS. The Fund is an ETF. Accordingly, it is subject to certain risks associated with its unique structure.

 

Market Participants Risk. Only an Authorized Participant may engage in creation or redemption transactions directly with the Fund, and none of those Authorized Participants is obligated to engage in creation and/or redemption transactions. The Fund has a limited number of institutions that may act as Authorized Participants on an agency basis (i.e., on behalf of other market participants). To the extent that Authorized Participants exit the business or are unable to proceed with creation or redemption orders with respect to the Fund and no other Authorized Participant is able to step forward to create or redeem, Fund Shares may be more likely to trade at a premium or discount to NAV and possibly face trading halts or delisting. The Fund may also rely on a small number of third-party market makers to provide a market for the purchase and sale of Fund Shares but such market makers are under no obligation to do so. Decisions by Authorized Participants or market makers to reduce their role or step away from these activities in times of market stress could inhibit the effectiveness of the arbitrage process in maintaining the relationship between the underlying values of the Fund’s portfolio securities and the Fund’s market price. Any trading halt or other problem relating to the trading activity of these market makers or any issues disrupting the Authorized Participants’ ability to proceed with creation and/or redemption orders could result in a dramatic change in the spread between the Fund’s net asset value and the price at which Fund Shares are trading on the Exchange, which could result in a decrease in value of Fund Shares. This reduced effectiveness could result in Fund Shares trading at a premium or discount to net asset value and also in greater than normal intraday bid-ask spreads Fund Shares.

 

Cash Transactions Risk. The Fund currently expects to effect a significant portion of its creations and redemptions for cash, rather than in-kind securities. Paying redemption proceeds in cash rather than through in-kind delivery of portfolio securities may require the Fund to dispose of or sell portfolio securities or other assets at an inopportune time to obtain the cash needed to meet redemption orders. This may cause the Fund to sell a security and recognize a capital gain or loss that might not have been incurred if it had made a redemption in-kind. As a result, the Fund may pay out higher or lower annual capital gains distributions than ETFs that redeem in-kind. The use of cash creations and redemptions may also cause the Fund’s Shares to trade in the market at greater bid-ask spreads or greater premiums or discounts to the Fund’s NAV. Furthermore, the Fund may not be able to execute cash transactions for creation and redemption purposes at the same price used to determine the Fund’s NAV. To the extent that the maximum additional charge for creation or redemption transactions is insufficient to cover the execution shortfall, the Fund’s performance could be negatively impacted.

 

Costs of Buying and Selling Fund Shares. Due to the costs of buying or selling Fund Shares, including brokerage commissions imposed by brokers and bid/ask spreads, frequent trading of Fund Shares may significantly reduce investment results and an investment in Fund Shares may not be advisable for investors who anticipate regularly making small investments.

 

Premium/Discount Risk. As with all ETFs, Fund Shares may be bought and sold in the secondary market at market prices. The trading prices of Fund Shares in the secondary market may differ from the Fund’s daily net asset value per share and there may be times when the market price of the shares is more than the net asset value per share (premium) or less than the net asset value per share (discount). If a shareholder purchases Fund Shares at a time when the market price is at a premium to the net asset value or sells Fund Shares at a time when the market price is at a discount to the net asset value, the shareholder may pay more for, or receive less than, the underlying value of the Fund Shares, respectively. This risk is heightened in times of market volatility or periods of steep market declines.

 

Trading Risks. Although Fund Shares are listed for trading on the Exchange and may be traded on U.S. exchanges other than the Exchange, there can be no assurance that Fund Shares will trade with any volume, or at all, on any stock exchange. In stressed market conditions, the liquidity of Fund Shares may begin to mirror the liquidity of the Fund’s underlying portfolio holdings, which can be significantly less liquid than Fund Shares. Trading in Fund Shares on the Exchange may be halted due to market conditions or for reasons that, in the view of the Exchange, make trading in Fund Shares inadvisable. In addition, trading in Fund Shares on the Exchange is subject to trading halts caused by extraordinary market volatility pursuant to the Exchange’s “circuit breaker” rules. There can be no assurance that the requirements of the Exchange necessary to maintain the listing of the Fund will continue to be met or will remain unchanged.

Roundhill RDDT WeeklyPay™ ETF | U.S. GOVERNMENT SECURITIES RISK  
Prospectus [Line Items]  
Risk [Text Block]

U.S. GOVERNMENT SECURITIES RISK. U.S. government securities are subject to interest rate risk but generally do not involve the credit risks associated with investments in other types of debt securities. As a result, the yields available from U.S. government securities are generally lower than the yields available from other debt securities. U.S. government securities are guaranteed only as to the timely payment of interest and the payment of principal when held to maturity.

Roundhill RDDT WeeklyPay™ ETF | VALUATION RISK  
Prospectus [Line Items]  
Risk [Text Block]

VALUATION RISK. The Fund may hold securities or other assets that may be valued on the basis of factors other than market quotations. This may occur because the asset or security does not trade on a centralized exchange, or in times of market turmoil or reduced liquidity. There are multiple methods that can be used to value a portfolio holding when market quotations are not readily available. The value established for any portfolio holding at a point in time might differ from what would be produced using a different methodology or if it had been priced using market quotations. Portfolio holdings that are valued using techniques other than market quotations, including “fair valued” assets or securities, may be subject to greater fluctuation in their valuations from one day to the next than if market quotations were used. In addition, there is no assurance that the Fund could sell or close out a portfolio position for the value established for it at any time, and it is possible that the Fund would incur a loss because a portfolio position is sold or closed out at a discount to the valuation established by the Fund at that time. The Fund’s ability to value investments may be impacted by technological issues or errors by pricing services or other third-party service providers.

Roundhill RDDT WeeklyPay™ ETF | EQUITY SECURITIES RISK  
Prospectus [Line Items]  
Risk [Text Block]

EQUITY SECURITIES RISK. Equity securities are subject to changes in value, and their values may be more volatile than those of other asset classes. Equity securities prices fluctuate for several reasons, including changes in investors’ perceptions of the financial condition of an issuer or the general condition of the relevant equity market, such as market volatility, or when political or economic events affecting an issuer occur. Common stock prices may be particularly sensitive to rising interest rates, as the cost of capital rises and borrowing costs increase. Common stocks generally subject their holders to more risks than preferred stocks and debt securities because common stockholders’ claims are subordinated to those of holders of preferred stocks and debt securities upon the bankruptcy of the issuer.

Roundhill RDDT WeeklyPay™ ETF | SWAP AGREEMENTS RISK  
Prospectus [Line Items]  
Risk [Text Block]

SWAP AGREEMENTS RISK. The Fund will utilize swap agreements to derive its exposure to shares of RDDT. Swap agreements may involve greater risks than direct investment in securities as they may be leveraged and are subject to credit risk, counterparty risk and valuation risk. A swap agreement could result in losses if the underlying reference or asset does not perform as anticipated. In addition, many swaps trade over-the-counter and may be considered illiquid. It may not be possible for the Fund to liquidate a swap position at an advantageous time or price, which may result in significant losses.

Roundhill RDDT WeeklyPay™ ETF | NEW FUND RISK

NEW FUND RISK. The Fund is a recently organized investment company with a limited operating history. As a result, prospective investors have a limited track record or history on which to base their investment decision.

Risk [Text Block]

REGULATED INVESTMENT COMPANY TAX RISKS. The Fund intends to qualify annually and to elect to be treated as a regulated investment company under the Internal Revenue Code of 1986, as amended (the “Code”). To qualify for the favorable U.S. federal income tax treatment generally accorded to regulated investment companies, the Fund must, among other things, (i) derive in each taxable year at least 90% of its gross income from dividends, interest, payments with respect to securities loans and gains from the sale or other disposition of stock, securities or foreign currencies or other income derived with respect to its business of investing in such stock, securities or currencies, or net income derived from interests in certain publicly traded partnerships; (ii) diversify its holdings so that, at the end of each quarter of the taxable year, (a) at least 50% of the market value of the Fund’s assets is represented by cash and cash items (including receivables), U.S. government securities, the securities of other regulated investment companies and other securities, with such other securities of any one issuer generally limited for the purposes of this calculation to an amount not greater than 5% of the value of the Fund’s total assets and not greater than 10% of the outstanding voting securities of such issuer, and (b) not more than 25% of the value of its total assets is invested in the securities (other than U.S. government securities or the securities of other regulated investment companies) of any one issuer, or two or more issuers which the Fund controls which are engaged in the same, similar or related trades or businesses, or the securities of one or more of certain publicly traded partnerships; and (iii) distribute at least 90% of its investment company taxable income (which includes, among other items, dividends, interest and net short-term capital gains in excess of net long-term capital losses) and at least 90% of its net tax-exempt interest income each taxable year. There are certain exceptions for failure to qualify if the failure is for reasonable cause or is de minimis, and certain corrective action is taken and certain tax payments are made by the Fund.

 

If the Fund were to fail to meet the qualifying income test or asset diversification test and fail to qualify as a RIC, it would be taxed in the same manner as an ordinary corporation, and distributions to its shareholders would not be deductible by the Fund in computing its taxable income, which would adversely affect the Fund’s performance.

Roundhill RDDT WeeklyPay™ ETF | LARGE SHAREHOLDER RISK  
Prospectus [Line Items]  
Risk [Text Block]

LARGE SHAREHOLDER RISK. Certain shareholders, including affiliated funds advised by the Adviser, may from time to time own a significant portion of the Fund’s shares. In addition, a third-party investor, the Adviser or an affiliate of the Adviser (“Affiliate”), an authorized participant, a market maker, or another entity may invest in the Fund and hold its investment for a limited period solely to facilitate the commencement of the Fund or to help the Fund achieve a specified size or scale. There can be no assurance that any large shareholder will not redeem its investment, that the size of the Fund will be maintained at such levels, or that the Fund will continue to meet applicable listing requirements. Redemptions by large shareholders could have a significant negative impact on the Fund. In addition, transactions by large shareholders may account for a large percentage of the trading volume on the Fund’s listing exchange and may, therefore, have a material upward or downward effect on the market price of the shares.

 

To the extent that a significant percentage of the Fund’s shares are owned or controlled by a small number of account shareholders (or a single account shareholder), including funds or accounts over which the Adviser or an Affiliate has investment discretion, the Fund is subject to the risk that those shareholders may purchase or redeem Fund shares in significant amounts rapidly or unexpectedly, including as a result of an asset allocation decision made by the Adviser or an Affiliate. This may adversely affect the Fund’s performance if the Adviser is forced to sell portfolio securities or invest cash when it would not otherwise choose to do so. Redemptions of a large number of shares may affect the liquidity of the Fund’s portfolio, increase the Fund’s transaction costs, and accelerate the realization of taxable income and/or gains. In addition, a large redemption could result in the Fund’s current expenses being allocated over a smaller asset base, leading to an increase in the Fund’s gross expense ratio. Large purchases of the Fund’s shares may also adversely affect the Fund’s performance to the extent that the Fund is delayed in investing new cash or otherwise maintains a larger cash position than it ordinarily would, particularly if the Fund accepts cash for an order for the purchase of creation units of the Fund’s shares.

Roundhill RDDT WeeklyPay™ ETF | RDDT INVESTING RISKS  
Prospectus [Line Items]  
Risk [Text Block]

RDDT INVESTING RISKS. The Fund will have significant exposure to RDDT through its investments in swap agreements that utilize RDDT as the reference asset. Accordingly, the Fund will subject to the risks of RDDT, set forth below.

 

RDDT ISSUER-SPECIFIC RISKS. Issuer-specific attributes may cause an investment held by the Fund to be more volatile than the market generally. The value of an individual security or particular type of security may be more volatile than the market as a whole and may perform differently from the value of the market as a whole. RDDT competes with other social media and content platforms for user attention and advertising dollars. The dynamic nature of the industry requires continuous innovation to maintain and grow its user base amidst evolving consumer preferences. A significant portion of RDDT’s revenue is derived from advertising. Economic downturns, changes in advertising budgets, or shifts in digital advertising trends could materially impact the company's financial health. RDDT’s platform relies heavily on user-generated content and active community participation. Any decline in user engagement or growth, as evidenced by recent reports of slower-than-expected user growth, could adversely affect advertising revenue and overall platform vitality. Given the vast amount of user-generated content, RDDT faces potential legal challenges related to hosting controversial or infringing material. Increased regulatory scrutiny or changes in content liability laws could necessitate stricter moderation policies, potentially impacting user experience and engagement. As a digital platform, RDDT is susceptible to technical issues, data breaches and cyberattacks. Ensuring robust cybersecurity measures and platform stability is crucial to maintaining user trust and preventing potential financial and reputational damage.

 

COMMUNICATION SERVICES COMPANIES RISK. Companies in the communication services sector may be affected by industry competition, substantial capital requirements, government regulation, and obsolescence of communications products and services due to technological advancement. Fluctuating domestic and international demand, shifting demographics and often unpredictable changes in consumer tastes can drastically affect a communication services company’s profitability. In addition, while all companies may be susceptible to network security breaches, certain companies in the communication services sector may be particular targets of hacking and potential theft of proprietary or consumer information or disruptions in service, which could have a material adverse effect on their businesses.

 

The communication services sector of a country’s economy is often subject to extensive government regulation. The costs of complying with governmental regulations, delays or failure to receive required regulatory approvals, or the enactment of new regulatory requirements may negatively affect the business of communications companies. Government actions around the world, specifically in the area of pre-marketing clearance of products and prices, can be arbitrary and unpredictable. The communications services industry can also be significantly affected by intense competition for market share, including competition with alternative technologies such as wireless communications, product compatibility and standardization, consumer preferences, rapid product obsolescence, research and development of new products, lack of standardization or compatibility with existing technologies, and a dependency on patent and copyright protections. Companies in the communication services sector may encounter distressed cash flows due to the need to commit substantial capital to meet increasing competition, particularly in developing new products and services using new technology. Technological innovations may make the products and services of certain communications companies obsolete.

 

INDIRECT INVESTMENT RISK. Reddit, Inc. is not affiliated with the Trust, the Fund, the Adviser, the Sub-Adviser or any affiliates thereof and is not involved with this offering in any way, and has no obligation to consider the Fund in taking any corporate actions that might affect the value of the Fund. The Trust, the Fund, the Adviser, the Sub-Adviser or any affiliate are not responsible for the performance of RDDT and make no representation as to the performance of RDDT. Investing in the Fund is not equivalent to investing in RDDT. Fund shareholders will not have voting rights or rights to receive dividends or other distributions or any other rights with respect to RDDT.

 

LARGE CAPITALIZATION COMPANIES RISK. Large capitalization companies may be less able than smaller capitalization companies to adapt to changing market conditions. Large capitalization companies may be more mature and subject to more limited growth potential compared with smaller capitalization companies. During different market cycles, the performance of large capitalization companies has trailed the overall performance of the broader securities markets.

 

MEDIA & ENTERTAINMENT COMPANIES RISK. The media & entertainment industry is influenced by evolving consumer preferences, technological advancements, content production costs, regulatory changes, and macroeconomic factors, all of which could contribute to volatility and potential losses. Media companies that rely on advertising revenue are exposed to economic cycles, as advertisers may reduce spending during economic downturns. The rise of digital ad-blocking tools and privacy regulations could further challenge ad-based business models. For those media & entertainment companies that rely on subscription-based revenue models, subscriber growth and retention depend on pricing strategies, content quality, and competition. A slowdown in new subscriptions or high churn rates could negatively impact revenue. The transition from traditional cable television to digital streaming platforms has disrupted the media landscape. Companies dependent on linear TV advertising or cable subscriptions face ongoing subscriber losses, while streaming services must continuously adapt to evolving consumption habits. Success in the entertainment industry depends on the ability to produce, acquire, and distribute compelling content. High production costs for original content, coupled with uncertainty about audience reception, can create financial risk. Even with significant investment, content success is unpredictable. Underperformance of major films, TV shows, or digital media projects can result in financial losses and damage brand value. Companies that license third-party content may face contract renegotiations, content losses, or increased licensing fees. Conversely, companies reliant on proprietary franchises must protect their intellectual property from piracy and unauthorized distribution.

 

UNITED STATES RISK. Certain changes in the U.S. economy, such as when the U.S. economy weakens or when its financial markets decline, may have an adverse effect on the securities to which the Fund has exposure.

NON-DIVERSIFICATION RISK. As a “non-diversified” fund, the Fund may hold a smaller number of portfolio securities than many other funds. To the extent the Fund invests in a relatively small number of issuers, a decline in the market value of a particular security held by the Fund may affect its value more than if it invested in a larger number of issuers. The value of the Fund Shares may be more volatile than the values of shares of more diversified funds.

Roundhill SHOP WeeklyPay™ ETF | MARKET RISK  
Prospectus [Line Items]  
Risk [Text Block]

MARKET RISK. Market risk is the risk that a particular investment, or Fund Shares in general, may fall in value. Securities are subject to market fluctuations caused by real or perceived adverse economic, political, and regulatory factors or market developments, changes in interest rates, disruptions to trade, impositions of tariffs and perceived trends in securities prices. Fund Shares could decline in value or underperform other investments. In addition, local, regional or global events such as war, acts of terrorism, market manipulation, government defaults, government shutdowns, regulatory actions, political changes, diplomatic developments, the imposition of sanctions and other similar measures, spread of infectious diseases or other public health issues, recessions, natural disasters, or other events could have a significant negative impact on the Fund and its investments. Any of such circumstances could have a materially negative impact on the value of Fund Shares, the liquidity of an investment, and may result in increased market volatility. During any such events, Fund Shares may trade at increased premiums or discounts to their net asset value, the bid/ask spread on Fund Shares may widen and the returns on investment may fluctuate.

Roundhill SHOP WeeklyPay™ ETF | LIQUIDITY RISK  
Prospectus [Line Items]  
Risk [Text Block]

LIQUIDITY RISK. The market for swap agreements that reference SHOP shares may be subject to periods of illiquidity. During such times it may be difficult or impossible to buy or sell a position at the desired price. Market disruptions or volatility can also make it difficult to find a counterparty willing to transact at a reasonable price and sufficient size. Illiquid markets may cause losses, which could be significant. The large size of the positions which the Fund may acquire increases the risk of illiquidity, may make its positions more difficult to liquidate, and may increase the losses incurred while trying to do so. Such large positions also may impact the price of swap agreements on SHOP shares.

Roundhill SHOP WeeklyPay™ ETF | ACTIVE MANAGEMENT RISK  
Prospectus [Line Items]

ACTIVE MANAGEMENT RISK. The Fund is actively-managed and its performance reflects investment decisions that the Adviser and/or Sub-Adviser makes for the Fund. Such judgments about the Fund’s investments may prove to be incorrect. If the investments selected and the strategies employed by the Fund fail to produce the intended results, the Fund could underperform as compared to other funds with similar investment objectives and/or strategies, or could have negative returns.

Roundhill SHOP WeeklyPay™ ETF | ACTIVE MARKET RISK

ACTIVE MARKET RISK. Although Fund Shares are listed for trading on the Exchange, there can be no assurance that an active trading market for Fund Shares will develop or be maintained. Fund Shares trade on the Exchange at market prices that may be below, at or above the Fund’s net asset value. Securities, including Fund Shares, are subject to market fluctuations and liquidity constraints that may be caused by such factors as economic, political, or regulatory developments, changes in interest rates, and/or perceived trends in securities prices. Fund Shares could decline in value or underperform other investments.

Roundhill SHOP WeeklyPay™ ETF | ASSET CLASS RISK

CONCENTRATION RISK. The Fund is susceptible to an increased risk of loss, including losses due to adverse events that affect the Fund’s investments more than the market as a whole, to the extent that the Fund’s investments are concentrated in investments that provide exposure to SHOP and the industry to which it is assigned.

Roundhill SHOP WeeklyPay™ ETF | COUNTERPARTY RISK

COUNTERPARTY RISK. Fund transactions involving a counterparty are subject to the risk that the counterparty will not fulfill its obligation to the Fund. Counterparty risk may arise because of the counterparty’s financial condition (i.e., financial difficulties, bankruptcy, or insolvency), market activities and developments, or other reasons, whether foreseen or not. A counterparty’s inability to fulfill its obligation may result in significant financial loss to the Fund. The Fund may be unable to recover its investment from the counterparty or may obtain a limited recovery, and/or recovery may be delayed.

Roundhill SHOP WeeklyPay™ ETF | CURRENT MARKET CONDITIONS RISK  
Prospectus [Line Items]  
Risk [Text Block]

CURRENT MARKET CONDITIONS RISK. Current market conditions risk is the risk that a particular investment, or Fund Shares in general, may fall in value due to current market conditions. As a means to fight inflation, which remains at elevated levels, the Federal Reserve and certain foreign central banks have raised interest rates; however, the Federal Reserve has recently lowered interest rates and may continue to do so. U.S. regulators have proposed several changes to market and issuer regulations which would directly impact the Fund, and any regulatory changes could adversely impact the Fund’s ability to achieve its investment strategies or make certain investments. Recent and potential future bank failures could result in disruption to the broader banking industry or markets generally and reduce confidence in financial institutions and the economy as a whole, which may also heighten market volatility and reduce liquidity. Additionally, challenges in commercial real estate markets, including rising interest rates, declining valuations and increasing vacancies, could have a broader impact on financial markets. The ongoing adversarial political climate in the United States, as well as political and diplomatic events both domestic and abroad, have and may continue to have an adverse impact the U.S. regulatory landscape, markets and investor behavior, which could have a negative impact on the Fund’s investments and operations. The change in administration resulting from the 2024 United States national elections could result in significant impacts to international trade relations, tax and immigration policies, and other aspects of the national and international political and financial landscape, which could affect, among other things, inflation and the securities markets generally. Other unexpected political, regulatory and diplomatic events within the U.S. and abroad may affect investor and consumer confidence and may adversely impact financial markets and the broader economy. For example, ongoing armed conflicts between Russia and Ukraine in Europe and among Israel, Iran, Hamas and other militant groups in the Middle East, have caused and could continue to cause significant market disruptions and volatility within the markets in Russia, Europe, the Middle East and the United States. The hostilities and sanctions resulting from those hostilities have and could continue to have a significant impact on certain Fund investments as well as Fund performance and liquidity. The economies of the United States and its trading partners, as well as the financial markets generally, may be adversely impacted by trade disputes, including the imposition of tariffs, and other matters. For example, the United States has imposed trade barriers and restrictions on China. In addition, the Chinese government is engaged in a longstanding dispute with Taiwan, continually threatening an invasion. If the political climate between the United States and China does not improve or continues to deteriorate, if China were to attempt invading Taiwan, or if other geopolitical conflicts develop or worsen, economies, markets and individual securities may be adversely affected, and the value of the Fund’s assets may go down. A public health crisis and the ensuing policies enacted by governments and central banks may cause significant volatility and uncertainty in global financial markets, negatively impacting global growth prospects. As the COVID-19 global pandemic illustrated, such events may affect certain geographic regions, countries, sectors and industries more significantly than others. Advancements in technology may also adversely impact markets and the overall performance of the Fund. For instance, the economy may be significantly impacted by the advanced development and increased regulation of artificial intelligence. Additionally, cyber security breaches of both government and non-government entities could have negative impacts on infrastructure and the ability of such entities, including the Fund, to operate properly. These events, and any other future events, may adversely affect the prices and liquidity of the Fund’s portfolio investments and could result in disruptions in the trading markets.

Roundhill SHOP WeeklyPay™ ETF | CYBERSECURITY RISK  
Prospectus [Line Items]  
Risk [Text Block]

CYBERSECURITY RISK. Failures or breaches of the electronic systems of the Fund, the Fund’s adviser, sub-adviser, distributor and other service providers, market makers, Authorized Participants or the issuers of securities in which the Fund invests have the ability to cause disruptions, negatively impact the Fund’s business operations and/or potentially result in financial losses to the Fund and its shareholders. While the Fund has established business continuity plans and risk management systems seeking to address system breaches or failures, there are inherent limitations in such plans and systems. Furthermore, the Fund cannot control the cybersecurity plans and systems of the Fund’s other service providers, market makers, Authorized Participants or issuers of securities in which the Fund invests.

Roundhill SHOP WeeklyPay™ ETF | DEBT SECURITIES RISK  
Prospectus [Line Items]  
Risk [Text Block]

DEBT SECURITIES RISK. Investments in debt securities subject the holder to the credit risk of the issuer. Credit risk refers to the possibility that the issuer or other obligor of a security will not be able or willing to make payments of interest and principal when due. Generally, the value of debt securities will change inversely with changes in interest rates. To the extent that interest rates rise, certain underlying obligations may be paid off substantially slower than originally anticipated and the value of those securities may fall sharply. During periods of falling interest rates, the income received by the Fund may decline. If the principal on a debt security is prepaid before expected, the prepayments of principal may have to be reinvested in obligations paying interest at lower rates. Debt securities generally do not trade on a securities exchange making them generally less liquid and more difficult to value than common stock.

Roundhill SHOP WeeklyPay™ ETF | DERIVATIVES RISK  
Prospectus [Line Items]  
Risk [Text Block]

DERIVATIVES RISK. The use of derivative instruments involves risks different from, or possibly greater than, the risks associated with investing directly in securities and other traditional investments. These risks include: (i) the risk that the counterparty to a derivative transaction may not fulfill its contractual obligations; (ii) risk of mispricing or improper valuation; and (iii) the risk that changes in the value of the derivative may not correlate perfectly with the underlying asset. Derivative prices are highly volatile and may fluctuate substantially during a short period of time. Such prices are influenced by numerous factors that affect the markets, including, but not limited to: changing supply and demand relationships; government programs and policies; national and international political and economic events, changes in interest rates, inflation and deflation and changes in supply and demand relationships. Trading derivative instruments involves risks different from, or possibly greater than, the risks associated with investing directly in securities. Derivative contracts ordinarily have leverage inherent in their terms. The use of leverage may cause the Fund to liquidate portfolio positions when it would not be advantageous to do so in order to satisfy its obligations or to meet regulatory or contractual requirements for derivatives. The use of derivatives can magnify potential for gain or loss and, therefore, amplify the effects of market volatility on share price.

Roundhill SHOP WeeklyPay™ ETF | DISTRIBUTION TAX RISK  
Prospectus [Line Items]  
Risk [Text Block]

DISTRIBUTION TAX RISK. The Fund currently expects to make distributions on a weekly basis. Such frequent distributions may expose investors to increased tax liabilities. However, these distributions may exceed the Fund’s income and gains for the Fund’s taxable year. Distributions in excess of the Fund’s current and accumulated earnings and profits will be treated as a return of capital. A return of capital distribution generally will not be taxable but will reduce the shareholder’s cost basis and will result in a higher capital gain or lower capital loss when those Fund Shares on which the distribution was received are sold. Once a Fund shareholder’s cost basis is reduced to zero, further distributions will be treated as capital gain if the Fund shareholder holds Fund Shares as capital assets. Additionally, any capital returned through distributions will be distributed after payment of Fund fees and expenses. Because a portion of the Fund’s distributions may consist of return of capital, the Fund may not be an appropriate investment for investors who do not want their principal investment in the Fund to decrease over time or who do not wish to receive return of capital in a given period. In the event that a shareholder purchases Fund Shares shortly before a distribution by the Fund, the entire distribution may be taxable to the shareholder even though a portion of the distribution effectively represents a return of the purchase price.

ETF RISK. The Fund may invest in ETFs. The value of an ETF held by the Fund will fluctuate over time based on fluctuations in the values of the assets held by the ETF, which may be affected by changes in general economic conditions, expectations for future growth and profits, interest rates and the supply and demand for those assets. When the Fund invests in an ETF, it will bear a proportionate share of the ETF’s expenses. Brokerage, tax and other expenses may negatively impact the performance of the ETF and, in turn, the value of the Fund Shares. An ETF that tracks an index may not exactly match the performance of the index due to cash drag, differences between the portfolio of the ETF and the components of the index, expenses and other factors.

Roundhill SHOP WeeklyPay™ ETF | INFLATION RISK

Risk [Text Block]

INFLATION RISK. Inflation risk is the risk that the value of assets or income from investments will be less in the future as inflation decreases the value of money. As inflation increases, the present value of the Fund’s assets and distributions may decline. This risk is more prevalent with respect to fixed income securities held by the Fund.

Roundhill SHOP WeeklyPay™ ETF | Interest Rate Risk [Member]  
Prospectus [Line Items]  
Risk [Text Block]

INTEREST RATE RISK. Interest rate risk is the risk that the value of the debt securities in the Fund’s portfolio will decline because of rising market interest rates. Interest rate risk is generally lower for shorter term debt securities and higher for longer-term debt securities. Duration is a reasonably accurate measure of a debt security’s price sensitivity to changes in interest rates and a common measure of interest rate risk. Duration measures a debt security’s expected life on a present value basis, taking into account the debt security’s yield, interest payments and final maturity. In general, duration represents the expected percentage change in the value of a security for an immediate 1% change in interest rates. For example, the price of a debt security with a three-year duration would be expected to drop by approximately 3% in response to a 1% increase in interest rates. Therefore, prices of debt securities with shorter durations tend to be less sensitive to interest rate changes than debt securities with longer durations. As the value of a debt security changes over time, so will its duration.

Roundhill SHOP WeeklyPay™ ETF | LEGISLATION AND LITIGATION RISK  
Prospectus [Line Items]  
Risk [Text Block]

LEGISLATION AND LITIGATION RISK. Legislation or litigation that affects the value of assets or securities held by the Fund may reduce the value of the Fund. From time to time, various legislative initiatives are proposed that may have a negative impact on certain assets or securities in which the Fund invests. In addition, litigation regarding any of the assets or securities owned by the Fund may negatively impact the value of the Shares. Such legislation or litigation may cause the Fund to lose value or may result in higher portfolio turnover if the Adviser determines to sell such a holding.

Roundhill SHOP WeeklyPay™ ETF | LEVERAGE RISK  
Prospectus [Line Items]  
Risk [Text Block]

LEVERAGE RISK. The Fund obtains investment exposure in excess of its net assets by utilizing leverage and may lose more money in market conditions that are adverse to its investment objectives than a fund that does not utilize leverage. An investment in the Fund is exposed to the risk that a decline in the weekly performance of shares of SHOP will be magnified. This means that an investment in the Fund will be reduced by an amount equal to 1.2% for every 1% weekly decline in the market value of the SHOP shares, not including the costs of financing leverage and other operating expenses, which would further reduce its value. The Fund could theoretically lose an amount greater than its net assets in the event the market value of SHOP shares decline more than 83.33% over a calendar week. Leverage will also have the effect of magnifying any differences in the Fund’s correlation with SHOP shares.

Roundhill SHOP WeeklyPay™ ETF | MONEY MARKET INSTRUMENTS RISK  
Prospectus [Line Items]  
Risk [Text Block]

MONEY MARKET INSTRUMENTS RISK. The value of money market instruments may be affected by changing interest rates and by changes in the credit ratings of the investments. If a significant amount of the Fund’s assets are invested in money market instruments, it will be more difficult for the Fund to achieve its investment objectives. An investment in a money market fund is not insured or guaranteed by the FDIC or any other government agency. It is possible to lose money by investing in a money market fund.

Roundhill SHOP WeeklyPay™ ETF | OPERATIONAL RISK  
Prospectus [Line Items]  
Risk [Text Block]

OPERATIONAL RISK. The Fund is subject to risks arising from various operational factors, including, but not limited to, human error, processing and communication errors, errors of the Fund’s service providers, counterparties or other third-parties, failed or inadequate processes and technology or systems failures. The Fund relies on third-parties for a range of services, including custody. Any delay or failure relating to engaging or maintaining such service providers may affect the Fund’s ability to meet its investment objectives. Although the Fund and the Adviser seek to reduce these operational risks through controls and procedures, there is no way to completely protect against such risks.

Roundhill SHOP WeeklyPay™ ETF | SPECIAL TAX RISK  
Prospectus [Line Items]  
Risk [Text Block]

SPECIAL TAX RISK. The Fund intends to qualify annually and to elect to be treated as a regulated investment company under the Internal Revenue Code of 1986, as amended (the “Code”). To qualify for the favorable U.S. federal income tax treatment generally accorded to regulated investment companies, the Fund must, among other things, (i) derive in each taxable year at least 90% of its gross income from dividends, interest, payments with respect to securities loans and gains from the sale or other disposition of stock, securities or foreign currencies or other income derived with respect to its business of investing in such stock, securities or currencies, or net income derived from interests in certain publicly traded partnerships; (ii) diversify its holdings so that, at the end of each quarter of the taxable year, (a) at least 50% of the market value of the Fund’s assets is represented by cash and cash items (including receivables), U.S. government securities, the securities of other regulated investment companies and other securities, with such other securities of any one issuer generally limited for the purposes of this calculation to an amount not greater than 5% of the value of the Fund’s total assets and not greater than 10% of the outstanding voting securities of such issuer, and (b) not more than 25% of the value of its total assets is invested in the securities (other than U.S. government securities or the securities of other regulated investment companies) of any one issuer, or two or more issuers which the Fund controls which are engaged in the same, similar or related trades or businesses, or the securities of one or more of certain publicly traded partnerships; and (iii) distribute at least 90% of its investment company taxable income (which includes, among other items, dividends, interest and net short-term capital gains in excess of net long-term capital losses) and at least 90% of its net tax-exempt interest income each taxable year. There are certain exceptions for failure to qualify if the failure is for reasonable cause or is de minimis, and certain corrective action is taken and certain tax payments are made by the Fund.

 

The authority with regard to swaps entered into by regulated investment companies is unclear both as to the qualification under the income test and the identification of the issuer under the diversification test. The Fund intends to take the position that because the swaps held by the Fund reference securities that the income on the swaps are “other income” from the Fund’s business of investing in stocks and securities. In addition, the Fund intends to manage its investments in the swaps so that neither the exposure to issuer of the referenced security nor the exposure to any one counterparty of the swaps will exceed 25% of the gross value of the Fund’s portfolio at the end of any quarter.

 

If the Fund were to fail to meet the qualifying income test or asset diversification test and fail to qualify as a RIC, it would be taxed in the same manner as an ordinary corporation, and distributions to its shareholders would not be deductible by the Fund in computing its taxable income, which would adversely affect the Fund’s performance.

Roundhill SHOP WeeklyPay™ ETF | STRUCTURAL ETF RISKS  
Prospectus [Line Items]  
Risk [Text Block]

STRUCTURAL ETF RISKS. The Fund is an ETF. Accordingly, it is subject to certain risks associated with its unique structure.

 

Market Participants Risk. Only an Authorized Participant may engage in creation or redemption transactions directly with the Fund, and none of those Authorized Participants is obligated to engage in creation and/or redemption transactions. The Fund has a limited number of institutions that may act as Authorized Participants on an agency basis (i.e., on behalf of other market participants). To the extent that Authorized Participants exit the business or are unable to proceed with creation or redemption orders with respect to the Fund and no other Authorized Participant is able to step forward to create or redeem, Fund Shares may be more likely to trade at a premium or discount to NAV and possibly face trading halts or delisting. The Fund may also rely on a small number of third-party market makers to provide a market for the purchase and sale of Fund Shares but such market makers are under no obligation to do so. Decisions by Authorized Participants or market makers to reduce their role or step away from these activities in times of market stress could inhibit the effectiveness of the arbitrage process in maintaining the relationship between the underlying values of the Fund’s portfolio securities and the Fund’s market price. Any trading halt or other problem relating to the trading activity of these market makers or any issues disrupting the Authorized Participants’ ability to proceed with creation and/or redemption orders could result in a dramatic change in the spread between the Fund’s net asset value and the price at which Fund Shares are trading on the Exchange, which could result in a decrease in value of Fund Shares. This reduced effectiveness could result in Fund Shares trading at a premium or discount to net asset value and also in greater than normal intraday bid-ask spreads Fund Shares.

 

Cash Transactions Risk. The Fund currently expects to effect a significant portion of its creations and redemptions for cash, rather than in-kind securities. Paying redemption proceeds in cash rather than through in-kind delivery of portfolio securities may require the Fund to dispose of or sell portfolio securities or other assets at an inopportune time to obtain the cash needed to meet redemption orders. This may cause the Fund to sell a security and recognize a capital gain or loss that might not have been incurred if it had made a redemption in-kind. As a result, the Fund may pay out higher or lower annual capital gains distributions than ETFs that redeem in-kind. The use of cash creations and redemptions may also cause the Fund’s Shares to trade in the market at greater bid-ask spreads or greater premiums or discounts to the Fund’s NAV. Furthermore, the Fund may not be able to execute cash transactions for creation and redemption purposes at the same price used to determine the Fund’s NAV. To the extent that the maximum additional charge for creation or redemption transactions is insufficient to cover the execution shortfall, the Fund’s performance could be negatively impacted.

 

Costs of Buying and Selling Fund Shares. Due to the costs of buying or selling Fund Shares, including brokerage commissions imposed by brokers and bid/ask spreads, frequent trading of Fund Shares may significantly reduce investment results and an investment in Fund Shares may not be advisable for investors who anticipate regularly making small investments.

 

Premium/Discount Risk. As with all ETFs, Fund Shares may be bought and sold in the secondary market at market prices. The trading prices of Fund Shares in the secondary market may differ from the Fund’s daily net asset value per share and there may be times when the market price of the shares is more than the net asset value per share (premium) or less than the net asset value per share (discount). If a shareholder purchases Fund Shares at a time when the market price is at a premium to the net asset value or sells Fund Shares at a time when the market price is at a discount to the net asset value, the shareholder may pay more for, or receive less than, the underlying value of the Fund Shares, respectively. This risk is heightened in times of market volatility or periods of steep market declines.

 

Trading Risks. Although Fund Shares are listed for trading on the Exchange and may be traded on U.S. exchanges other than the Exchange, there can be no assurance that Fund Shares will trade with any volume, or at all, on any stock exchange. In stressed market conditions, the liquidity of Fund Shares may begin to mirror the liquidity of the Fund’s underlying portfolio holdings, which can be significantly less liquid than Fund Shares. Trading in Fund Shares on the Exchange may be halted due to market conditions or for reasons that, in the view of the Exchange, make trading in Fund Shares inadvisable. In addition, trading in Fund Shares on the Exchange is subject to trading halts caused by extraordinary market volatility pursuant to the Exchange’s “circuit breaker” rules. There can be no assurance that the requirements of the Exchange necessary to maintain the listing of the Fund will continue to be met or will remain unchanged.

Roundhill SHOP WeeklyPay™ ETF | U.S. GOVERNMENT SECURITIES RISK  
Prospectus [Line Items]  
Risk [Text Block]

U.S. GOVERNMENT SECURITIES RISK. U.S. government securities are subject to interest rate risk but generally do not involve the credit risks associated with investments in other types of debt securities. As a result, the yields available from U.S. government securities are generally lower than the yields available from other debt securities. U.S. government securities are guaranteed only as to the timely payment of interest and the payment of principal when held to maturity.

Roundhill SHOP WeeklyPay™ ETF | VALUATION RISK  
Prospectus [Line Items]  
Risk [Text Block]

VALUATION RISK. The Fund may hold securities or other assets that may be valued on the basis of factors other than market quotations. This may occur because the asset or security does not trade on a centralized exchange, or in times of market turmoil or reduced liquidity. There are multiple methods that can be used to value a portfolio holding when market quotations are not readily available. The value established for any portfolio holding at a point in time might differ from what would be produced using a different methodology or if it had been priced using market quotations. Portfolio holdings that are valued using techniques other than market quotations, including “fair valued” assets or securities, may be subject to greater fluctuation in their valuations from one day to the next than if market quotations were used. In addition, there is no assurance that the Fund could sell or close out a portfolio position for the value established for it at any time, and it is possible that the Fund would incur a loss because a portfolio position is sold or closed out at a discount to the valuation established by the Fund at that time. The Fund’s ability to value investments may be impacted by technological issues or errors by pricing services or other third-party service providers.

Roundhill SHOP WeeklyPay™ ETF | EQUITY SECURITIES RISK  
Prospectus [Line Items]  
Risk [Text Block]

EQUITY SECURITIES RISK. Equity securities are subject to changes in value, and their values may be more volatile than those of other asset classes. Equity securities prices fluctuate for several reasons, including changes in investors’ perceptions of the financial condition of an issuer or the general condition of the relevant equity market, such as market volatility, or when political or economic events affecting an issuer occur. Common stock prices may be particularly sensitive to rising interest rates, as the cost of capital rises and borrowing costs increase. Common stocks generally subject their holders to more risks than preferred stocks and debt securities because common stockholders’ claims are subordinated to those of holders of preferred stocks and debt securities upon the bankruptcy of the issuer.

Roundhill SHOP WeeklyPay™ ETF | SWAP AGREEMENTS RISK  
Prospectus [Line Items]  
Risk [Text Block]

SWAP AGREEMENTS RISK. The Fund will utilize swap agreements to derive its exposure to shares of SHOP. Swap agreements may involve greater risks than direct investment in securities as they may be leveraged and are subject to credit risk, counterparty risk and valuation risk. A swap agreement could result in losses if the underlying reference or asset does not perform as anticipated. In addition, many swaps trade over-the-counter and may be considered illiquid. It may not be possible for the Fund to liquidate a swap position at an advantageous time or price, which may result in significant losses.

Roundhill SHOP WeeklyPay™ ETF | NEW FUND RISK  
Prospectus [Line Items]  
Risk [Text Block]

NEW FUND RISK. The Fund is a recently organized investment company with a limited operating history. As a result, prospective investors have a limited track record or history on which to base their investment decision.

Roundhill SHOP WeeklyPay™ ETF | REGULATED INVESTMENT COMPANY TAX RISKS  
Prospectus [Line Items]  
Risk [Text Block]

REGULATED INVESTMENT COMPANY TAX RISKS. The Fund intends to qualify annually and to elect to be treated as a regulated investment company under the Internal Revenue Code of 1986, as amended (the “Code”). To qualify for the favorable U.S. federal income tax treatment generally accorded to regulated investment companies, the Fund must, among other things, (i) derive in each taxable year at least 90% of its gross income from dividends, interest, payments with respect to securities loans and gains from the sale or other disposition of stock, securities or foreign currencies or other income derived with respect to its business of investing in such stock, securities or currencies, or net income derived from interests in certain publicly traded partnerships; (ii) diversify its holdings so that, at the end of each quarter of the taxable year, (a) at least 50% of the market value of the Fund’s assets is represented by cash and cash items (including receivables), U.S. government securities, the securities of other regulated investment companies and other securities, with such other securities of any one issuer generally limited for the purposes of this calculation to an amount not greater than 5% of the value of the Fund’s total assets and not greater than 10% of the outstanding voting securities of such issuer, and (b) not more than 25% of the value of its total assets is invested in the securities (other than U.S. government securities or the securities of other regulated investment companies) of any one issuer, or two or more issuers which the Fund controls which are engaged in the same, similar or related trades or businesses, or the securities of one or more of certain publicly traded partnerships; and (iii) distribute at least 90% of its investment company taxable income (which includes, among other items, dividends, interest and net short-term capital gains in excess of net long-term capital losses) and at least 90% of its net tax-exempt interest income each taxable year. There are certain exceptions for failure to qualify if the failure is for reasonable cause or is de minimis, and certain corrective action is taken and certain tax payments are made by the Fund.

 

If the Fund were to fail to meet the qualifying income test or asset diversification test and fail to qualify as a RIC, it would be taxed in the same manner as an ordinary corporation, and distributions to its shareholders would not be deductible by the Fund in computing its taxable income, which would adversely affect the Fund’s performance.

Roundhill SHOP WeeklyPay™ ETF | LARGE SHAREHOLDER RISK  
Prospectus [Line Items]  
Risk [Text Block]

LARGE SHAREHOLDER RISK. Certain shareholders, including affiliated funds advised by the Adviser, may from time to time own a significant portion of the Fund’s shares. In addition, a third-party investor, the Adviser or an affiliate of the Adviser (“Affiliate”), an authorized participant, a market maker, or another entity may invest in the Fund and hold its investment for a limited period solely to facilitate the commencement of the Fund or to help the Fund achieve a specified size or scale. There can be no assurance that any large shareholder will not redeem its investment, that the size of the Fund will be maintained at such levels, or that the Fund will continue to meet applicable listing requirements. Redemptions by large shareholders could have a significant negative impact on the Fund. In addition, transactions by large shareholders may account for a large percentage of the trading volume on the Fund’s listing exchange and may, therefore, have a material upward or downward effect on the market price of the shares.

 

To the extent that a significant percentage of the Fund’s shares are owned or controlled by a small number of account shareholders (or a single account shareholder), including funds or accounts over which the Adviser or an Affiliate has investment discretion, the Fund is subject to the risk that those shareholders may purchase or redeem Fund shares in significant amounts rapidly or unexpectedly, including as a result of an asset allocation decision made by the Adviser or an Affiliate. This may adversely affect the Fund’s performance if the Adviser is forced to sell portfolio securities or invest cash when it would not otherwise choose to do so. Redemptions of a large number of shares may affect the liquidity of the Fund’s portfolio, increase the Fund’s transaction costs, and accelerate the realization of taxable income and/or gains. In addition, a large redemption could result in the Fund’s current expenses being allocated over a smaller asset base, leading to an increase in the Fund’s gross expense ratio. Large purchases of the Fund’s shares may also adversely affect the Fund’s performance to the extent that the Fund is delayed in investing new cash or otherwise maintains a larger cash position than it ordinarily would, particularly if the Fund accepts cash for an order for the purchase of creation units of the Fund’s shares.

Roundhill SHOP WeeklyPay™ ETF | SHOP INVESTING RISKS  
Prospectus [Line Items]  
Risk [Text Block]

SHOP INVESTING RISKS. The Fund will have significant exposure to SHOP through its investments in swap agreements that utilize SHOP as the reference asset. Accordingly, the Fund will subject to the risks of SHOP, set forth below.

 

SHOP ISSUER-SPECIFIC RISKS. Issuer-specific attributes may cause an investment held by the Fund to be more volatile than the market generally. The value of an individual security or particular type of security may be more volatile than the market as a whole and may perform differently from the value of the market as a whole. SHOP faces significant competition. Increased competition could lead to pricing pressure, customer churn and higher acquisition costs. A large portion of SHOP’s customer base consists of small and mid-sized business and entrepreneurs, which are more vulnerable to economic downturns, inflation and shifts in consumer behavior. A decline in new business creation could impact SHOP’s revenue growth. SHOP generates revenue from subscription fees and merchant services. Any slowdown in merchant adoption, lower transaction volumes, or loss of large enterprise customers could impact revenue. SHOP’s revenue depends on merchant sales performance, which is influenced by consumer spending trends, economic conditions, inflation and supply chain disruptions. A decline in discretionary spending could negatively impact transaction volume. SHOP’s cloud-based infrastructure requires constant upkeep and security. Any platform outages, service disruptions or cyberattacks could impact merchant trust and lead to financial losses. SHOP handles large volumes of merchant and consumer data, making it subject to data protection regulations. Stricter compliance requirements or security breaches could result in legal liabilities and reputational damage. SHOP earns revenue in multiple currencies, exposing it to currency fluctuations and macroeconomic instability in key markets. A strong U.S. dollar could negatively impact international revenue.

 

INDIRECT INVESTMENT RISK. Shopify Inc. is not affiliated with the Trust, the Fund, the Adviser, the Sub-Adviser or any affiliates thereof and is not involved with this offering in any way, and has no obligation to consider the Fund in taking any corporate actions that might affect the value of the Fund. The Trust, the Fund, the Adviser, the Sub-Adviser or any affiliate are not responsible for the performance of SHOP and make no representation as to the performance of SHOP. Investing in the Fund is not equivalent to investing in SHOP. Fund shareholders will not have voting rights or rights to receive dividends or other distributions or any other rights with respect to SHOP.

 

INFORMATION TECHNOLOGY COMPANIES RISK. Information technology companies face intense competition, both domestically and internationally, which may have an adverse effect on profit margins. Like other technology companies, information technology companies may have limited product lines, markets, financial resources or personnel. The products of information technology companies may face obsolescence due to rapid technological developments, frequent new product introduction, unpredictable changes in growth rates and competition for the services of qualified personnel. Companies in the information technology sector are heavily dependent on patent and intellectual property rights. The loss or impairment of these rights may adversely affect the profitability of these companies. Information technology companies are facing increased government and regulatory scrutiny and may be subject to adverse government or regulatory action.

 

LARGE CAPITALIZATION COMPANIES RISK. Large capitalization companies may be less able than smaller capitalization companies to adapt to changing market conditions. Large capitalization companies may be more mature and subject to more limited growth potential compared with smaller capitalization companies. During different market cycles, the performance of large capitalization companies has trailed the overall performance of the broader securities markets.

 

NON-U.S. SECURITIES RISK. Non-U.S. securities are subject to higher volatility than securities of domestic issuers due to possible adverse political, social or economic developments, restrictions on foreign investment or exchange of securities, capital controls, lack of liquidity, currency exchange rates, excessive taxation, government seizure of assets, the imposition of sanctions by foreign governments, different legal or accounting standards, and less government supervision and regulation of securities exchanges in foreign countries.

NON-DIVERSIFICATION RISK. As a “non-diversified” fund, the Fund may hold a smaller number of portfolio securities than many other funds. To the extent the Fund invests in a relatively small number of issuers, a decline in the market value of a particular security held by the Fund may affect its value more than if it invested in a larger number of issuers. The value of the Fund Shares may be more volatile than the values of shares of more diversified funds.

Roundhill SPOT WeeklyPay™ ETF | MARKET RISK  
Prospectus [Line Items]  
Risk [Text Block]

MARKET RISK. Market risk is the risk that a particular investment, or Fund Shares in general, may fall in value. Securities are subject to market fluctuations caused by real or perceived adverse economic, political, and regulatory factors or market developments, changes in interest rates, disruptions to trade, impositions of tariffs and perceived trends in securities prices. Fund Shares could decline in value or underperform other investments. In addition, local, regional or global events such as war, acts of terrorism, market manipulation, government defaults, government shutdowns, regulatory actions, political changes, diplomatic developments, the imposition of sanctions and other similar measures, spread of infectious diseases or other public health issues, recessions, natural disasters, or other events could have a significant negative impact on the Fund and its investments. Any of such circumstances could have a materially negative impact on the value of Fund Shares, the liquidity of an investment, and may result in increased market volatility. During any such events, Fund Shares may trade at increased premiums or discounts to their net asset value, the bid/ask spread on Fund Shares may widen and the returns on investment may fluctuate.

Roundhill SPOT WeeklyPay™ ETF | LIQUIDITY RISK  
Prospectus [Line Items]  
Risk [Text Block]

LIQUIDITY RISK. The market for swap agreements that reference SPOT shares may be subject to periods of illiquidity. During such times it may be difficult or impossible to buy or sell a position at the desired price. Market disruptions or volatility can also make it difficult to find a counterparty willing to transact at a reasonable price and sufficient size. Illiquid markets may cause losses, which could be significant. The large size of the positions which the Fund may acquire increases the risk of illiquidity, may make its positions more difficult to liquidate, and may increase the losses incurred while trying to do so. Such large positions also may impact the price of swap agreements on SPOT shares.

Roundhill SPOT WeeklyPay™ ETF | ACTIVE MANAGEMENT RISK  
Prospectus [Line Items]  
Risk [Text Block]

ACTIVE MANAGEMENT RISK. The Fund is actively-managed and its performance reflects investment decisions that the Adviser and/or Sub-Adviser makes for the Fund. Such judgments about the Fund’s investments may prove to be incorrect. If the investments selected and the strategies employed by the Fund fail to produce the intended results, the Fund could underperform as compared to other funds with similar investment objectives and/or strategies, or could have negative returns.

Roundhill SPOT WeeklyPay™ ETF | ACTIVE MARKET RISK  
Prospectus [Line Items]  
Risk [Text Block]

ACTIVE MARKET RISK. Although Fund Shares are listed for trading on the Exchange, there can be no assurance that an active trading market for Fund Shares will develop or be maintained. Fund Shares trade on the Exchange at market prices that may be below, at or above the Fund’s net asset value. Securities, including Fund Shares, are subject to market fluctuations and liquidity constraints that may be caused by such factors as economic, political, or regulatory developments, changes in interest rates, and/or perceived trends in securities prices. Fund Shares could decline in value or underperform other investments.

CONCENTRATION RISK. The Fund is susceptible to an increased risk of loss, including losses due to adverse events that affect the Fund’s investments more than the market as a whole, to the extent that the Fund’s investments are concentrated in investments that provide exposure to SPOT and the industry to which it is assigned.

Roundhill SPOT WeeklyPay™ ETF | COUNTERPARTY RISK  
Prospectus [Line Items]  
Risk [Text Block]

COUNTERPARTY RISK. Fund transactions involving a counterparty are subject to the risk that the counterparty will not fulfill its obligation to the Fund. Counterparty risk may arise because of the counterparty’s financial condition (i.e., financial difficulties, bankruptcy, or insolvency), market activities and developments, or other reasons, whether foreseen or not. A counterparty’s inability to fulfill its obligation may result in significant financial loss to the Fund. The Fund may be unable to recover its investment from the counterparty or may obtain a limited recovery, and/or recovery may be delayed.

CREDIT RISK. An issuer or other obligated party of a debt security may be unable or unwilling to make dividend, interest and/or principal payments when due. In addition, the value of a debt security may decline because of concerns about the issuer’s ability or unwillingness to make such payments.

Roundhill SPOT WeeklyPay™ ETF | CURRENT MARKET CONDITIONS RISK  
Prospectus [Line Items]  
Risk [Text Block]

CURRENT MARKET CONDITIONS RISK. Current market conditions risk is the risk that a particular investment, or Fund Shares in general, may fall in value due to current market conditions. As a means to fight inflation, which remains at elevated levels, the Federal Reserve and certain foreign central banks have raised interest rates; however, the Federal Reserve has recently lowered interest rates and may continue to do so. U.S. regulators have proposed several changes to market and issuer regulations which would directly impact the Fund, and any regulatory changes could adversely impact the Fund’s ability to achieve its investment strategies or make certain investments. Recent and potential future bank failures could result in disruption to the broader banking industry or markets generally and reduce confidence in financial institutions and the economy as a whole, which may also heighten market volatility and reduce liquidity. Additionally, challenges in commercial real estate markets, including rising interest rates, declining valuations and increasing vacancies, could have a broader impact on financial markets. The ongoing adversarial political climate in the United States, as well as political and diplomatic events both domestic and abroad, have and may continue to have an adverse impact the U.S. regulatory landscape, markets and investor behavior, which could have a negative impact on the Fund’s investments and operations. The change in administration resulting from the 2024 United States national elections could result in significant impacts to international trade relations, tax and immigration policies, and other aspects of the national and international political and financial landscape, which could affect, among other things, inflation and the securities markets generally. Other unexpected political, regulatory and diplomatic events within the U.S. and abroad may affect investor and consumer confidence and may adversely impact financial markets and the broader economy. For example, ongoing armed conflicts between Russia and Ukraine in Europe and among Israel, Iran, Hamas and other militant groups in the Middle East, have caused and could continue to cause significant market disruptions and volatility within the markets in Russia, Europe, the Middle East and the United States. The hostilities and sanctions resulting from those hostilities have and could continue to have a significant impact on certain Fund investments as well as Fund performance and liquidity. The economies of the United States and its trading partners, as well as the financial markets generally, may be adversely impacted by trade disputes, including the imposition of tariffs, and other matters. For example, the United States has imposed trade barriers and restrictions on China. In addition, the Chinese government is engaged in a longstanding dispute with Taiwan, continually threatening an invasion. If the political climate between the United States and China does not improve or continues to deteriorate, if China were to attempt invading Taiwan, or if other geopolitical conflicts develop or worsen, economies, markets and individual securities may be adversely affected, and the value of the Fund’s assets may go down. A public health crisis and the ensuing policies enacted by governments and central banks may cause significant volatility and uncertainty in global financial markets, negatively impacting global growth prospects. As the COVID-19 global pandemic illustrated, such events may affect certain geographic regions, countries, sectors and industries more significantly than others. Advancements in technology may also adversely impact markets and the overall performance of the Fund. For instance, the economy may be significantly impacted by the advanced development and increased regulation of artificial intelligence. Additionally, cyber security breaches of both government and non-government entities could have negative impacts on infrastructure and the ability of such entities, including the Fund, to operate properly. These events, and any other future events, may adversely affect the prices and liquidity of the Fund’s portfolio investments and could result in disruptions in the trading markets.

Roundhill SPOT WeeklyPay™ ETF | CYBERSECURITY RISK

Risk [Text Block]

CYBERSECURITY RISK. Failures or breaches of the electronic systems of the Fund, the Fund’s adviser, sub-adviser, distributor and other service providers, market makers, Authorized Participants or the issuers of securities in which the Fund invests have the ability to cause disruptions, negatively impact the Fund’s business operations and/or potentially result in financial losses to the Fund and its shareholders. While the Fund has established business continuity plans and risk management systems seeking to address system breaches or failures, there are inherent limitations in such plans and systems. Furthermore, the Fund cannot control the cybersecurity plans and systems of the Fund’s other service providers, market makers, Authorized Participants or issuers of securities in which the Fund invests.

Credit risk refers to the possibility that the issuer or other obligor of a security will not be able or willing to make payments of interest and principal when due. Generally, the value of debt securities will change inversely with changes in interest rates. To the extent that interest rates rise, certain underlying obligations may be paid off substantially slower than originally anticipated and the value of those securities may fall sharply. During periods of falling interest rates, the income received by the Fund may decline. If the principal on a debt security is prepaid before expected, the prepayments of principal may have to be reinvested in obligations paying interest at lower rates. Debt securities generally do not trade on a securities exchange making them generally less liquid and more difficult to value than common stock.

Roundhill SPOT WeeklyPay™ ETF | DERIVATIVES RISK  
Prospectus [Line Items]  
Risk [Text Block]

DERIVATIVES RISK. The use of derivative instruments involves risks different from, or possibly greater than, the risks associated with investing directly in securities and other traditional investments. These risks include: (i) the risk that the counterparty to a derivative transaction may not fulfill its contractual obligations; (ii) risk of mispricing or improper valuation; and (iii) the risk that changes in the value of the derivative may not correlate perfectly with the underlying asset. Derivative prices are highly volatile and may fluctuate substantially during a short period of time. Such prices are influenced by numerous factors that affect the markets, including, but not limited to: changing supply and demand relationships; government programs and policies; national and international political and economic events, changes in interest rates, inflation and deflation and changes in supply and demand relationships. Trading derivative instruments involves risks different from, or possibly greater than, the risks associated with investing directly in securities. Derivative contracts ordinarily have leverage inherent in their terms. The use of leverage may cause the Fund to liquidate portfolio positions when it would not be advantageous to do so in order to satisfy its obligations or to meet regulatory or contractual requirements for derivatives. The use of derivatives can magnify potential for gain or loss and, therefore, amplify the effects of market volatility on share price.

Roundhill SPOT WeeklyPay™ ETF | DISTRIBUTION TAX RISK  
Prospectus [Line Items]  
Risk [Text Block]

DISTRIBUTION TAX RISK. The Fund currently expects to make distributions on a weekly basis. Such frequent distributions may expose investors to increased tax liabilities. However, these distributions may exceed the Fund’s income and gains for the Fund’s taxable year. Distributions in excess of the Fund’s current and accumulated earnings and profits will be treated as a return of capital. A return of capital distribution generally will not be taxable but will reduce the shareholder’s cost basis and will result in a higher capital gain or lower capital loss when those Fund Shares on which the distribution was received are sold. Once a Fund shareholder’s cost basis is reduced to zero, further distributions will be treated as capital gain if the Fund shareholder holds Fund Shares as capital assets. Additionally, any capital returned through distributions will be distributed after payment of Fund fees and expenses. Because a portion of the Fund’s distributions may consist of return of capital, the Fund may not be an appropriate investment for investors who do not want their principal investment in the Fund to decrease over time or who do not wish to receive return of capital in a given period. In the event that a shareholder purchases Fund Shares shortly before a distribution by the Fund, the entire distribution may be taxable to the shareholder even though a portion of the distribution effectively represents a return of the purchase price.

Roundhill SPOT WeeklyPay™ ETF | ETF RISK  
Prospectus [Line Items]  
Risk [Text Block]

ETF RISK. The Fund may invest in ETFs. The value of an ETF held by the Fund will fluctuate over time based on fluctuations in the values of the assets held by the ETF, which may be affected by changes in general economic conditions, expectations for future growth and profits, interest rates and the supply and demand for those assets. When the Fund invests in an ETF, it will bear a proportionate share of the ETF’s expenses. Brokerage, tax and other expenses may negatively impact the performance of the ETF and, in turn, the value of the Fund Shares. An ETF that tracks an index may not exactly match the performance of the index due to cash drag, differences between the portfolio of the ETF and the components of the index, expenses and other factors.

Roundhill SPOT WeeklyPay™ ETF | INFLATION RISK  
Prospectus [Line Items]  
Risk [Text Block]

INFLATION RISK. Inflation risk is the risk that the value of assets or income from investments will be less in the future as inflation decreases the value of money. As inflation increases, the present value of the Fund’s assets and distributions may decline. This risk is more prevalent with respect to fixed income securities held by the Fund.

Roundhill SPOT WeeklyPay™ ETF | Interest Rate Risk [Member]  
Prospectus [Line Items]  
Risk [Text Block]

INTEREST RATE RISK. Interest rate risk is the risk that the value of the debt securities in the Fund’s portfolio will decline because of rising market interest rates. Interest rate risk is generally lower for shorter term debt securities and higher for longer-term debt securities. Duration is a reasonably accurate measure of a debt security’s price sensitivity to changes in interest rates and a common measure of interest rate risk. Duration measures a debt security’s expected life on a present value basis, taking into account the debt security’s yield, interest payments and final maturity. In general, duration represents the expected percentage change in the value of a security for an immediate 1% change in interest rates. For example, the price of a debt security with a three-year duration would be expected to drop by approximately 3% in response to a 1% increase in interest rates. Therefore, prices of debt securities with shorter durations tend to be less sensitive to interest rate changes than debt securities with longer durations. As the value of a debt security changes over time, so will its duration.

Roundhill SPOT WeeklyPay™ ETF | LEGISLATION AND LITIGATION RISK  
Prospectus [Line Items]  
Risk [Text Block]

LEGISLATION AND LITIGATION RISK. Legislation or litigation that affects the value of assets or securities held by the Fund may reduce the value of the Fund. From time to time, various legislative initiatives are proposed that may have a negative impact on certain assets or securities in which the Fund invests. In addition, litigation regarding any of the assets or securities owned by the Fund may negatively impact the value of the Shares. Such legislation or litigation may cause the Fund to lose value or may result in higher portfolio turnover if the Adviser determines to sell such a holding.

Roundhill SPOT WeeklyPay™ ETF | LEVERAGE RISK  
Prospectus [Line Items]  
Risk [Text Block]

LEVERAGE RISK. The Fund obtains investment exposure in excess of its net assets by utilizing leverage and may lose more money in market conditions that are adverse to its investment objectives than a fund that does not utilize leverage. An investment in the Fund is exposed to the risk that a decline in the weekly performance of shares of SPOT will be magnified. This means that an investment in the Fund will be reduced by an amount equal to 1.2% for every 1% weekly decline in the market value of the SPOT shares, not including the costs of financing leverage and other operating expenses, which would further reduce its value. The Fund could theoretically lose an amount greater than its net assets in the event the market value of SPOT shares decline more than 83.33% over a calendar week. Leverage will also have the effect of magnifying any differences in the Fund’s correlation with SPOT shares.

Roundhill SPOT WeeklyPay™ ETF | MONEY MARKET INSTRUMENTS RISK  
Prospectus [Line Items]  
Risk [Text Block]

MONEY MARKET INSTRUMENTS RISK. The value of money market instruments may be affected by changing interest rates and by changes in the credit ratings of the investments. If a significant amount of the Fund’s assets are invested in money market instruments, it will be more difficult for the Fund to achieve its investment objectives. An investment in a money market fund is not insured or guaranteed by the FDIC or any other government agency. It is possible to lose money by investing in a money market fund.

Roundhill SPOT WeeklyPay™ ETF | OPERATIONAL RISK  
Prospectus [Line Items]  
Risk [Text Block]

OPERATIONAL RISK. The Fund is subject to risks arising from various operational factors, including, but not limited to, human error, processing and communication errors, errors of the Fund’s service providers, counterparties or other third-parties, failed or inadequate processes and technology or systems failures. The Fund relies on third-parties for a range of services, including custody. Any delay or failure relating to engaging or maintaining such service providers may affect the Fund’s ability to meet its investment objectives. Although the Fund and the Adviser seek to reduce these operational risks through controls and procedures, there is no way to completely protect against such risks.

Roundhill SPOT WeeklyPay™ ETF | SPECIAL TAX RISK  
Prospectus [Line Items]  
Risk [Text Block]

SPECIAL TAX RISK. The Fund intends to qualify annually and to elect to be treated as a regulated investment company under the Internal Revenue Code of 1986, as amended (the “Code”). To qualify for the favorable U.S. federal income tax treatment generally accorded to regulated investment companies, the Fund must, among other things, (i) derive in each taxable year at least 90% of its gross income from dividends, interest, payments with respect to securities loans and gains from the sale or other disposition of stock, securities or foreign currencies or other income derived with respect to its business of investing in such stock, securities or currencies, or net income derived from interests in certain publicly traded partnerships; (ii) diversify its holdings so that, at the end of each quarter of the taxable year, (a) at least 50% of the market value of the Fund’s assets is represented by cash and cash items (including receivables), U.S. government securities, the securities of other regulated investment companies and other securities, with such other securities of any one issuer generally limited for the purposes of this calculation to an amount not greater than 5% of the value of the Fund’s total assets and not greater than 10% of the outstanding voting securities of such issuer, and (b) not more than 25% of the value of its total assets is invested in the securities (other than U.S. government securities or the securities of other regulated investment companies) of any one issuer, or two or more issuers which the Fund controls which are engaged in the same, similar or related trades or businesses, or the securities of one or more of certain publicly traded partnerships; and (iii) distribute at least 90% of its investment company taxable income (which includes, among other items, dividends, interest and net short-term capital gains in excess of net long-term capital losses) and at least 90% of its net tax-exempt interest income each taxable year. There are certain exceptions for failure to qualify if the failure is for reasonable cause or is de minimis, and certain corrective action is taken and certain tax payments are made by the Fund.

 

The authority with regard to swaps entered into by regulated investment companies is unclear both as to the qualification under the income test and the identification of the issuer under the diversification test. The Fund intends to take the position that because the swaps held by the Fund reference securities that the income on the swaps are “other income” from the Fund’s business of investing in stocks and securities. In addition, the Fund intends to manage its investments in the swaps so that neither the exposure to issuer of the referenced security nor the exposure to any one counterparty of the swaps will exceed 25% of the gross value of the Fund’s portfolio at the end of any quarter.

 

If the Fund were to fail to meet the qualifying income test or asset diversification test and fail to qualify as a RIC, it would be taxed in the same manner as an ordinary corporation, and distributions to its shareholders would not be deductible by the Fund in computing its taxable income, which would adversely affect the Fund’s performance.

Roundhill SPOT WeeklyPay™ ETF | STRUCTURAL ETF RISKS  
Prospectus [Line Items]  
Risk [Text Block]

STRUCTURAL ETF RISKS. The Fund is an ETF. Accordingly, it is subject to certain risks associated with its unique structure.

 

Market Participants Risk. Only an Authorized Participant may engage in creation or redemption transactions directly with the Fund, and none of those Authorized Participants is obligated to engage in creation and/or redemption transactions. The Fund has a limited number of institutions that may act as Authorized Participants on an agency basis (i.e., on behalf of other market participants). To the extent that Authorized Participants exit the business or are unable to proceed with creation or redemption orders with respect to the Fund and no other Authorized Participant is able to step forward to create or redeem, Fund Shares may be more likely to trade at a premium or discount to NAV and possibly face trading halts or delisting. The Fund may also rely on a small number of third-party market makers to provide a market for the purchase and sale of Fund Shares but such market makers are under no obligation to do so. Decisions by Authorized Participants or market makers to reduce their role or step away from these activities in times of market stress could inhibit the effectiveness of the arbitrage process in maintaining the relationship between the underlying values of the Fund’s portfolio securities and the Fund’s market price. Any trading halt or other problem relating to the trading activity of these market makers or any issues disrupting the Authorized Participants’ ability to proceed with creation and/or redemption orders could result in a dramatic change in the spread between the Fund’s net asset value and the price at which Fund Shares are trading on the Exchange, which could result in a decrease in value of Fund Shares. This reduced effectiveness could result in Fund Shares trading at a premium or discount to net asset value and also in greater than normal intraday bid-ask spreads Fund Shares.

 

Cash Transactions Risk. The Fund currently expects to effect a significant portion of its creations and redemptions for cash, rather than in-kind securities. Paying redemption proceeds in cash rather than through in-kind delivery of portfolio securities may require the Fund to dispose of or sell portfolio securities or other assets at an inopportune time to obtain the cash needed to meet redemption orders. This may cause the Fund to sell a security and recognize a capital gain or loss that might not have been incurred if it had made a redemption in-kind. As a result, the Fund may pay out higher or lower annual capital gains distributions than ETFs that redeem in-kind. The use of cash creations and redemptions may also cause the Fund’s Shares to trade in the market at greater bid-ask spreads or greater premiums or discounts to the Fund’s NAV. Furthermore, the Fund may not be able to execute cash transactions for creation and redemption purposes at the same price used to determine the Fund’s NAV. To the extent that the maximum additional charge for creation or redemption transactions is insufficient to cover the execution shortfall, the Fund’s performance could be negatively impacted.

 

Costs of Buying and Selling Fund Shares. Due to the costs of buying or selling Fund Shares, including brokerage commissions imposed by brokers and bid/ask spreads, frequent trading of Fund Shares may significantly reduce investment results and an investment in Fund Shares may not be advisable for investors who anticipate regularly making small investments.

 

Premium/Discount Risk. As with all ETFs, Fund Shares may be bought and sold in the secondary market at market prices. The trading prices of Fund Shares in the secondary market may differ from the Fund’s daily net asset value per share and there may be times when the market price of the shares is more than the net asset value per share (premium) or less than the net asset value per share (discount). If a shareholder purchases Fund Shares at a time when the market price is at a premium to the net asset value or sells Fund Shares at a time when the market price is at a discount to the net asset value, the shareholder may pay more for, or receive less than, the underlying value of the Fund Shares, respectively. This risk is heightened in times of market volatility or periods of steep market declines.

 

Trading Risks. Although Fund Shares are listed for trading on the Exchange and may be traded on U.S. exchanges other than the Exchange, there can be no assurance that Fund Shares will trade with any volume, or at all, on any stock exchange. In stressed market conditions, the liquidity of Fund Shares may begin to mirror the liquidity of the Fund’s underlying portfolio holdings, which can be significantly less liquid than Fund Shares. Trading in Fund Shares on the Exchange may be halted due to market conditions or for reasons that, in the view of the Exchange, make trading in Fund Shares inadvisable. In addition, trading in Fund Shares on the Exchange is subject to trading halts caused by extraordinary market volatility pursuant to the Exchange’s “circuit breaker” rules. There can be no assurance that the requirements of the Exchange necessary to maintain the listing of the Fund will continue to be met or will remain unchanged.

Roundhill SPOT WeeklyPay™ ETF | U.S. GOVERNMENT SECURITIES RISK  
Prospectus [Line Items]  
Risk [Text Block]

U.S. GOVERNMENT SECURITIES RISK. U.S. government securities are subject to interest rate risk but generally do not involve the credit risks associated with investments in other types of debt securities. As a result, the yields available from U.S. government securities are generally lower than the yields available from other debt securities. U.S. government securities are guaranteed only as to the timely payment of interest and the payment of principal when held to maturity.

Roundhill SPOT WeeklyPay™ ETF | VALUATION RISK  
Prospectus [Line Items]  
Risk [Text Block]

VALUATION RISK. The Fund may hold securities or other assets that may be valued on the basis of factors other than market quotations. This may occur because the asset or security does not trade on a centralized exchange, or in times of market turmoil or reduced liquidity. There are multiple methods that can be used to value a portfolio holding when market quotations are not readily available. The value established for any portfolio holding at a point in time might differ from what would be produced using a different methodology or if it had been priced using market quotations. Portfolio holdings that are valued using techniques other than market quotations, including “fair valued” assets or securities, may be subject to greater fluctuation in their valuations from one day to the next than if market quotations were used. In addition, there is no assurance that the Fund could sell or close out a portfolio position for the value established for it at any time, and it is possible that the Fund would incur a loss because a portfolio position is sold or closed out at a discount to the valuation established by the Fund at that time. The Fund’s ability to value investments may be impacted by technological issues or errors by pricing services or other third-party service providers.

Roundhill SPOT WeeklyPay™ ETF | EQUITY SECURITIES RISK  
Prospectus [Line Items]  
Risk [Text Block]

EQUITY SECURITIES RISK. Equity securities are subject to changes in value, and their values may be more volatile than those of other asset classes. Equity securities prices fluctuate for several reasons, including changes in investors’ perceptions of the financial condition of an issuer or the general condition of the relevant equity market, such as market volatility, or when political or economic events affecting an issuer occur. Common stock prices may be particularly sensitive to rising interest rates, as the cost of capital rises and borrowing costs increase. Common stocks generally subject their holders to more risks than preferred stocks and debt securities because common stockholders’ claims are subordinated to those of holders of preferred stocks and debt securities upon the bankruptcy of the issuer.

Roundhill SPOT WeeklyPay™ ETF | SWAP AGREEMENTS RISK  
Prospectus [Line Items]  
Risk [Text Block]

SWAP AGREEMENTS RISK. The Fund will utilize swap agreements to derive its exposure to shares of SPOT. Swap agreements may involve greater risks than direct investment in securities as they may be leveraged and are subject to credit risk, counterparty risk and valuation risk. A swap agreement could result in losses if the underlying reference or asset does not perform as anticipated. In addition, many swaps trade over-the-counter and may be considered illiquid. It may not be possible for the Fund to liquidate a swap position at an advantageous time or price, which may result in significant losses.

Roundhill SPOT WeeklyPay™ ETF | NEW FUND RISK  
Prospectus [Line Items]

NEW FUND RISK. The Fund is a recently organized investment company with a limited operating history. As a result, prospective investors have a limited track record or history on which to base their investment decision.

Roundhill SPOT WeeklyPay™ ETF | REGULATED INVESTMENT COMPANY TAX RISKS  
Prospectus [Line Items]  
Risk [Text Block]

REGULATED INVESTMENT COMPANY TAX RISKS. The Fund intends to qualify annually and to elect to be treated as a regulated investment company under the Internal Revenue Code of 1986, as amended (the “Code”). To qualify for the favorable U.S. federal income tax treatment generally accorded to regulated investment companies, the Fund must, among other things, (i) derive in each taxable year at least 90% of its gross income from dividends, interest, payments with respect to securities loans and gains from the sale or other disposition of stock, securities or foreign currencies or other income derived with respect to its business of investing in such stock, securities or currencies, or net income derived from interests in certain publicly traded partnerships; (ii) diversify its holdings so that, at the end of each quarter of the taxable year, (a) at least 50% of the market value of the Fund’s assets is represented by cash and cash items (including receivables), U.S. government securities, the securities of other regulated investment companies and other securities, with such other securities of any one issuer generally limited for the purposes of this calculation to an amount not greater than 5% of the value of the Fund’s total assets and not greater than 10% of the outstanding voting securities of such issuer, and (b) not more than 25% of the value of its total assets is invested in the securities (other than U.S. government securities or the securities of other regulated investment companies) of any one issuer, or two or more issuers which the Fund controls which are engaged in the same, similar or related trades or businesses, or the securities of one or more of certain publicly traded partnerships; and (iii) distribute at least 90% of its investment company taxable income (which includes, among other items, dividends, interest and net short-term capital gains in excess of net long-term capital losses) and at least 90% of its net tax-exempt interest income each taxable year. There are certain exceptions for failure to qualify if the failure is for reasonable cause or is de minimis, and certain corrective action is taken and certain tax payments are made by the Fund.

 

If the Fund were to fail to meet the qualifying income test or asset diversification test and fail to qualify as a RIC, it would be taxed in the same manner as an ordinary corporation, and distributions to its shareholders would not be deductible by the Fund in computing its taxable income, which would adversely affect the Fund’s performance.

Roundhill SPOT WeeklyPay™ ETF | LARGE SHAREHOLDER RISK  
Prospectus [Line Items]  
Risk [Text Block]

LARGE SHAREHOLDER RISK. Certain shareholders, including affiliated funds advised by the Adviser, may from time to time own a significant portion of the Fund’s shares. In addition, a third-party investor, the Adviser or an affiliate of the Adviser (“Affiliate”), an authorized participant, a market maker, or another entity may invest in the Fund and hold its investment for a limited period solely to facilitate the commencement of the Fund or to help the Fund achieve a specified size or scale. There can be no assurance that any large shareholder will not redeem its investment, that the size of the Fund will be maintained at such levels, or that the Fund will continue to meet applicable listing requirements. Redemptions by large shareholders could have a significant negative impact on the Fund. In addition, transactions by large shareholders may account for a large percentage of the trading volume on the Fund’s listing exchange and may, therefore, have a material upward or downward effect on the market price of the shares.

 

To the extent that a significant percentage of the Fund’s shares are owned or controlled by a small number of account shareholders (or a single account shareholder), including funds or accounts over which the Adviser or an Affiliate has investment discretion, the Fund is subject to the risk that those shareholders may purchase or redeem Fund shares in significant amounts rapidly or unexpectedly, including as a result of an asset allocation decision made by the Adviser or an Affiliate. This may adversely affect the Fund’s performance if the Adviser is forced to sell portfolio securities or invest cash when it would not otherwise choose to do so. Redemptions of a large number of shares may affect the liquidity of the Fund’s portfolio, increase the Fund’s transaction costs, and accelerate the realization of taxable income and/or gains. In addition, a large redemption could result in the Fund’s current expenses being allocated over a smaller asset base, leading to an increase in the Fund’s gross expense ratio. Large purchases of the Fund’s shares may also adversely affect the Fund’s performance to the extent that the Fund is delayed in investing new cash or otherwise maintains a larger cash position than it ordinarily would, particularly if the Fund accepts cash for an order for the purchase of creation units of the Fund’s shares.

Roundhill SPOT WeeklyPay™ ETF | SPOT INVESTING RISKS  
Prospectus [Line Items]  
Risk [Text Block]

SPOT INVESTING RISKS. The Fund will have significant exposure to SPOT through its investments in swap agreements that utilize SPOT as the reference asset. Accordingly, the Fund will subject to the risks of SPOT, set forth below.

 

SPOT ISSUER-SPECIFIC RISKS. Issuer-specific attributes may cause an investment held by the Fund to be more volatile than the market generally. The value of an individual security or particular type of security may be more volatile than the market as a whole and may perform differently from the value of the market as a whole. SPOT faces significant competition from other streaming services, satellite radio services and social media platforms for user attention and advertising dollars. In mature markets like North America and Europe, SPOT faces slower subscriber growth and increased churn rates. Future growth depends on expansion into emerging markets, which may have lower revenue per user and higher regulatory risks. SPOT does not own the majority of its music content. Rising content acquisition costs and exclusivity deals could impact long-term profitability. One of SPOT’s largest expenses is royalty payments to music rights holders, including record labels, artists and publishers. Any increase in royalty rates or unfavorable renegotiations could pressure margins. While SPOT has expanded its ad-supported revenue model, advertising revenue remains highly cyclical and sensitive to economic downturns. A slowdown in digital ad spending could negatively impact SPOT’s profitability. SPOT operates a cloud-based digital streaming platform that relies on third-party infrastructure providers. Server outages, cybersecurity threats or data breaches could disrupt services and impact user trust. SPOT subscriptions are discretionary spending items. Economic downturns or inflationary pressures could lead to higher subscription cancellations. Spotify operates globally, generating revenue in multiple currencies. Exchange rate fluctuations can impact reported earnings and financial performance.

 

COMMUNICATION SERVICES COMPANIES RISK. Companies in the communication services sector may be affected by industry competition, substantial capital requirements, government regulation, and obsolescence of communications products and services due to technological advancement. Fluctuating domestic and international demand, shifting demographics and often unpredictable changes in consumer tastes can drastically affect a communication services company’s profitability. In addition, while all companies may be susceptible to network security breaches, certain companies in the communication services sector may be particular targets of hacking and potential theft of proprietary or consumer information or disruptions in service, which could have a material adverse effect on their businesses.

 

The communication services sector of a country’s economy is often subject to extensive government regulation. The costs of complying with governmental regulations, delays or failure to receive required regulatory approvals, or the enactment of new regulatory requirements may negatively affect the business of communications companies. Government actions around the world, specifically in the area of pre-marketing clearance of products and prices, can be arbitrary and unpredictable. The communications services industry can also be significantly affected by intense competition for market share, including competition with alternative technologies such as wireless communications, product compatibility and standardization, consumer preferences, rapid product obsolescence, research and development of new products, lack of standardization or compatibility with existing technologies, and a dependency on patent and copyright protections. Companies in the communication services sector may encounter distressed cash flows due to the need to commit substantial capital to meet increasing competition, particularly in developing new products and services using new technology. Technological innovations may make the products and services of certain communications companies obsolete.

 

INDIRECT INVESTMENT RISK. Spotify Technology S.A. is not affiliated with the Trust, the Fund, the Adviser, the Sub-Adviser or any affiliates thereof and is not involved with this offering in any way, and has no obligation to consider the Fund in taking any corporate actions that might affect the value of the Fund. The Trust, the Fund, the Adviser, the Sub-Adviser or any affiliate are not responsible for the performance of SPOT and make no representation as to the performance of SPOT. Investing in the Fund is not equivalent to investing in SPOT. Fund shareholders will not have voting rights or rights to receive dividends or other distributions or any other rights with respect to SPOT.

 

LARGE CAPITALIZATION COMPANIES RISK. Large capitalization companies may be less able than smaller capitalization companies to adapt to changing market conditions. Large capitalization companies may be more mature and subject to more limited growth potential compared with smaller capitalization companies. During different market cycles, the performance of large capitalization companies has trailed the overall performance of the broader securities markets.

 

MEDIA & ENTERTAINMENT COMPANIES RISK. The media & entertainment industry is influenced by evolving consumer preferences, technological advancements, content production costs, regulatory changes, and macroeconomic factors, all of which could contribute to volatility and potential losses. Media companies that rely on advertising revenue are exposed to economic cycles, as advertisers may reduce spending during economic downturns. The rise of digital ad-blocking tools and privacy regulations could further challenge ad-based business models. For those media & entertainment companies that rely on subscription-based revenue models, subscriber growth and retention depend on pricing strategies, content quality, and competition. A slowdown in new subscriptions or high churn rates could negatively impact revenue. The transition from traditional cable television to digital streaming platforms has disrupted the media landscape. Companies dependent on linear TV advertising or cable subscriptions face ongoing subscriber losses, while streaming services must continuously adapt to evolving consumption habits. Success in the entertainment industry depends on the ability to produce, acquire, and distribute compelling content. High production costs for original content, coupled with uncertainty about audience reception, can create financial risk. Even with significant investment, content success is unpredictable. Underperformance of major films, TV shows, or digital media projects can result in financial losses and damage brand value. Companies that license third-party content may face contract renegotiations, content losses, or increased licensing fees. Conversely, companies reliant on proprietary franchises must protect their intellectual property from piracy and unauthorized distribution.

 

NON-U.S. SECURITIES RISK. Non-U.S. securities are subject to higher volatility than securities of domestic issuers due to possible adverse political, social or economic developments, restrictions on foreign investment or exchange of securities, capital controls, lack of liquidity, currency exchange rates, excessive taxation, government seizure of assets, the imposition of sanctions by foreign governments, different legal or accounting standards, and less government supervision and regulation of securities exchanges in foreign countries.

NON-DIVERSIFICATION RISK. As a “non-diversified” fund, the Fund may hold a smaller number of portfolio securities than many other funds. To the extent the Fund invests in a relatively small number of issuers, a decline in the market value of a particular security held by the Fund may affect its value more than if it invested in a larger number of issuers. The value of the Fund Shares may be more volatile than the values of shares of more diversified funds.

Roundhill UBER WeeklyPay™ ETF | MARKET RISK  
Prospectus [Line Items]  
Risk [Text Block]

MARKET RISK. Market risk is the risk that a particular investment, or Fund Shares in general, may fall in value. Securities are subject to market fluctuations caused by real or perceived adverse economic, political, and regulatory factors or market developments, changes in interest rates, disruptions to trade, impositions of tariffs and perceived trends in securities prices. Fund Shares could decline in value or underperform other investments. In addition, local, regional or global events such as war, acts of terrorism, market manipulation, government defaults, government shutdowns, regulatory actions, political changes, diplomatic developments, the imposition of sanctions and other similar measures, spread of infectious diseases or other public health issues, recessions, natural disasters, or other events could have a significant negative impact on the Fund and its investments. Any of such circumstances could have a materially negative impact on the value of Fund Shares, the liquidity of an investment, and may result in increased market volatility. During any such events, Fund Shares may trade at increased premiums or discounts to their net asset value, the bid/ask spread on Fund Shares may widen and the returns on investment may fluctuate.

Roundhill UBER WeeklyPay™ ETF | LIQUIDITY RISK  
Prospectus [Line Items]  
Risk [Text Block]

LIQUIDITY RISK. The market for swap agreements that reference UBER shares may be subject to periods of illiquidity. During such times it may be difficult or impossible to buy or sell a position at the desired price. Market disruptions or volatility can also make it difficult to find a counterparty willing to transact at a reasonable price and sufficient size. Illiquid markets may cause losses, which could be significant. The large size of the positions which the Fund may acquire increases the risk of illiquidity, may make its positions more difficult to liquidate, and may increase the losses incurred while trying to do so. Such large positions also may impact the price of swap agreements on UBER shares.

Roundhill UBER WeeklyPay™ ETF | ACTIVE MANAGEMENT RISK

ACTIVE MANAGEMENT RISK. The Fund is actively-managed and its performance reflects investment decisions that the Adviser and/or Sub-Adviser makes for the Fund. Such judgments about the Fund’s investments may prove to be incorrect. If the investments selected and the strategies employed by the Fund fail to produce the intended results, the Fund could underperform as compared to other funds with similar investment objectives and/or strategies, or could have negative returns.

Roundhill UBER WeeklyPay™ ETF | ACTIVE MARKET RISK

ACTIVE MARKET RISK. Although Fund Shares are listed for trading on the Exchange, there can be no assurance that an active trading market for Fund Shares will develop or be maintained. Fund Shares trade on the Exchange at market prices that may be below, at or above the Fund’s net asset value. Securities, including Fund Shares, are subject to market fluctuations and liquidity constraints that may be caused by such factors as economic, political, or regulatory developments, changes in interest rates, and/or perceived trends in securities prices. Fund Shares could decline in value or underperform other investments.

The Fund is susceptible to an increased risk of loss, including losses due to adverse events that affect the Fund’s investments more than the market as a whole, to the extent that the Fund’s investments are concentrated in investments that provide exposure to UBER and the industry to which it is assigned.

Roundhill UBER WeeklyPay™ ETF | COUNTERPARTY RISK

Risk [Text Block]

COUNTERPARTY RISK. Fund transactions involving a counterparty are subject to the risk that the counterparty will not fulfill its obligation to the Fund. Counterparty risk may arise because of the counterparty’s financial condition (i.e., financial difficulties, bankruptcy, or insolvency), market activities and developments, or other reasons, whether foreseen or not. A counterparty’s inability to fulfill its obligation may result in significant financial loss to the Fund. The Fund may be unable to recover its investment from the counterparty or may obtain a limited recovery, and/or recovery may be delayed.

CREDIT RISK. An issuer or other obligated party of a debt security may be unable or unwilling to make dividend, interest and/or principal payments when due. In addition, the value of a debt security may decline because of concerns about the issuer’s ability or unwillingness to make such payments.

Roundhill UBER WeeklyPay™ ETF | CURRENT MARKET CONDITIONS RISK  
Prospectus [Line Items]  
Risk [Text Block]

CURRENT MARKET CONDITIONS RISK. Current market conditions risk is the risk that a particular investment, or Fund Shares in general, may fall in value due to current market conditions. As a means to fight inflation, which remains at elevated levels, the Federal Reserve and certain foreign central banks have raised interest rates; however, the Federal Reserve has recently lowered interest rates and may continue to do so. U.S. regulators have proposed several changes to market and issuer regulations which would directly impact the Fund, and any regulatory changes could adversely impact the Fund’s ability to achieve its investment strategies or make certain investments. Recent and potential future bank failures could result in disruption to the broader banking industry or markets generally and reduce confidence in financial institutions and the economy as a whole, which may also heighten market volatility and reduce liquidity. Additionally, challenges in commercial real estate markets, including rising interest rates, declining valuations and increasing vacancies, could have a broader impact on financial markets. The ongoing adversarial political climate in the United States, as well as political and diplomatic events both domestic and abroad, have and may continue to have an adverse impact the U.S. regulatory landscape, markets and investor behavior, which could have a negative impact on the Fund’s investments and operations. The change in administration resulting from the 2024 United States national elections could result in significant impacts to international trade relations, tax and immigration policies, and other aspects of the national and international political and financial landscape, which could affect, among other things, inflation and the securities markets generally. Other unexpected political, regulatory and diplomatic events within the U.S. and abroad may affect investor and consumer confidence and may adversely impact financial markets and the broader economy. For example, ongoing armed conflicts between Russia and Ukraine in Europe and among Israel, Iran, Hamas and other militant groups in the Middle East, have caused and could continue to cause significant market disruptions and volatility within the markets in Russia, Europe, the Middle East and the United States. The hostilities and sanctions resulting from those hostilities have and could continue to have a significant impact on certain Fund investments as well as Fund performance and liquidity. The economies of the United States and its trading partners, as well as the financial markets generally, may be adversely impacted by trade disputes, including the imposition of tariffs, and other matters. For example, the United States has imposed trade barriers and restrictions on China. In addition, the Chinese government is engaged in a longstanding dispute with Taiwan, continually threatening an invasion. If the political climate between the United States and China does not improve or continues to deteriorate, if China were to attempt invading Taiwan, or if other geopolitical conflicts develop or worsen, economies, markets and individual securities may be adversely affected, and the value of the Fund’s assets may go down. A public health crisis and the ensuing policies enacted by governments and central banks may cause significant volatility and uncertainty in global financial markets, negatively impacting global growth prospects. As the COVID-19 global pandemic illustrated, such events may affect certain geographic regions, countries, sectors and industries more significantly than others. Advancements in technology may also adversely impact markets and the overall performance of the Fund. For instance, the economy may be significantly impacted by the advanced development and increased regulation of artificial intelligence. Additionally, cyber security breaches of both government and non-government entities could have negative impacts on infrastructure and the ability of such entities, including the Fund, to operate properly. These events, and any other future events, may adversely affect the prices and liquidity of the Fund’s portfolio investments and could result in disruptions in the trading markets.

Roundhill UBER WeeklyPay™ ETF | CYBERSECURITY RISK  
Prospectus [Line Items]  
Risk [Text Block]

CYBERSECURITY RISK. Failures or breaches of the electronic systems of the Fund, the Fund’s adviser, sub-adviser, distributor and other service providers, market makers, Authorized Participants or the issuers of securities in which the Fund invests have the ability to cause disruptions, negatively impact the Fund’s business operations and/or potentially result in financial losses to the Fund and its shareholders. While the Fund has established business continuity plans and risk management systems seeking to address system breaches or failures, there are inherent limitations in such plans and systems. Furthermore, the Fund cannot control the cybersecurity plans and systems of the Fund’s other service providers, market makers, Authorized Participants or issuers of securities in which the Fund invests.

Roundhill UBER WeeklyPay™ ETF | DEBT SECURITIES RISK  
Prospectus [Line Items]  
Risk [Text Block]

DEBT SECURITIES RISK. Investments in debt securities subject the holder to the credit risk of the issuer. Credit risk refers to the possibility that the issuer or other obligor of a security will not be able or willing to make payments of interest and principal when due. Generally, the value of debt securities will change inversely with changes in interest rates. To the extent that interest rates rise, certain underlying obligations may be paid off substantially slower than originally anticipated and the value of those securities may fall sharply. During periods of falling interest rates, the income received by the Fund may decline. If the principal on a debt security is prepaid before expected, the prepayments of principal may have to be reinvested in obligations paying interest at lower rates. Debt securities generally do not trade on a securities exchange making them generally less liquid and more difficult to value than common stock.

Roundhill UBER WeeklyPay™ ETF | DERIVATIVES RISK  
Prospectus [Line Items]  
Risk [Text Block]

DERIVATIVES RISK. The use of derivative instruments involves risks different from, or possibly greater than, the risks associated with investing directly in securities and other traditional investments. These risks include: (i) the risk that the counterparty to a derivative transaction may not fulfill its contractual obligations; (ii) risk of mispricing or improper valuation; and (iii) the risk that changes in the value of the derivative may not correlate perfectly with the underlying asset. Derivative prices are highly volatile and may fluctuate substantially during a short period of time. Such prices are influenced by numerous factors that affect the markets, including, but not limited to: changing supply and demand relationships; government programs and policies; national and international political and economic events, changes in interest rates, inflation and deflation and changes in supply and demand relationships. Trading derivative instruments involves risks different from, or possibly greater than, the risks associated with investing directly in securities. Derivative contracts ordinarily have leverage inherent in their terms. The use of leverage may cause the Fund to liquidate portfolio positions when it would not be advantageous to do so in order to satisfy its obligations or to meet regulatory or contractual requirements for derivatives. The use of derivatives can magnify potential for gain or loss and, therefore, amplify the effects of market volatility on share price.

Roundhill UBER WeeklyPay™ ETF | DISTRIBUTION TAX RISK  
Prospectus [Line Items]  
Risk [Text Block]

DISTRIBUTION TAX RISK. The Fund currently expects to make distributions on a weekly basis. Such frequent distributions may expose investors to increased tax liabilities. However, these distributions may exceed the Fund’s income and gains for the Fund’s taxable year. Distributions in excess of the Fund’s current and accumulated earnings and profits will be treated as a return of capital. A return of capital distribution generally will not be taxable but will reduce the shareholder’s cost basis and will result in a higher capital gain or lower capital loss when those Fund Shares on which the distribution was received are sold. Once a Fund shareholder’s cost basis is reduced to zero, further distributions will be treated as capital gain if the Fund shareholder holds Fund Shares as capital assets. Additionally, any capital returned through distributions will be distributed after payment of Fund fees and expenses. Because a portion of the Fund’s distributions may consist of return of capital, the Fund may not be an appropriate investment for investors who do not want their principal investment in the Fund to decrease over time or who do not wish to receive return of capital in a given period. In the event that a shareholder purchases Fund Shares shortly before a distribution by the Fund, the entire distribution may be taxable to the shareholder even though a portion of the distribution effectively represents a return of the purchase price.

Roundhill UBER WeeklyPay™ ETF | ETF RISK  
Prospectus [Line Items]  
Risk [Text Block]

ETF RISK. The Fund may invest in ETFs. The value of an ETF held by the Fund will fluctuate over time based on fluctuations in the values of the assets held by the ETF, which may be affected by changes in general economic conditions, expectations for future growth and profits, interest rates and the supply and demand for those assets. When the Fund invests in an ETF, it will bear a proportionate share of the ETF’s expenses. Brokerage, tax and other expenses may negatively impact the performance of the ETF and, in turn, the value of the Fund Shares. An ETF that tracks an index may not exactly match the performance of the index due to cash drag, differences between the portfolio of the ETF and the components of the index, expenses and other factors.

Roundhill UBER WeeklyPay™ ETF | INFLATION RISK  
Prospectus [Line Items]  
Risk [Text Block]

INFLATION RISK. Inflation risk is the risk that the value of assets or income from investments will be less in the future as inflation decreases the value of money. As inflation increases, the present value of the Fund’s assets and distributions may decline. This risk is more prevalent with respect to fixed income securities held by the Fund.

Roundhill UBER WeeklyPay™ ETF | Interest Rate Risk [Member]  
Prospectus [Line Items]  
Risk [Text Block]

INTEREST RATE RISK. Interest rate risk is the risk that the value of the debt securities in the Fund’s portfolio will decline because of rising market interest rates. Interest rate risk is generally lower for shorter term debt securities and higher for longer-term debt securities. Duration is a reasonably accurate measure of a debt security’s price sensitivity to changes in interest rates and a common measure of interest rate risk. Duration measures a debt security’s expected life on a present value basis, taking into account the debt security’s yield, interest payments and final maturity. In general, duration represents the expected percentage change in the value of a security for an immediate 1% change in interest rates. For example, the price of a debt security with a three-year duration would be expected to drop by approximately 3% in response to a 1% increase in interest rates. Therefore, prices of debt securities with shorter durations tend to be less sensitive to interest rate changes than debt securities with longer durations. As the value of a debt security changes over time, so will its duration.

Roundhill UBER WeeklyPay™ ETF | LEGISLATION AND LITIGATION RISK  
Prospectus [Line Items]  
Risk [Text Block]

LEGISLATION AND LITIGATION RISK. Legislation or litigation that affects the value of assets or securities held by the Fund may reduce the value of the Fund. From time to time, various legislative initiatives are proposed that may have a negative impact on certain assets or securities in which the Fund invests. In addition, litigation regarding any of the assets or securities owned by the Fund may negatively impact the value of the Shares. Such legislation or litigation may cause the Fund to lose value or may result in higher portfolio turnover if the Adviser determines to sell such a holding.

Roundhill UBER WeeklyPay™ ETF | LEVERAGE RISK  
Prospectus [Line Items]  
Risk [Text Block]

LEVERAGE RISK. The Fund obtains investment exposure in excess of its net assets by utilizing leverage and may lose more money in market conditions that are adverse to its investment objectives than a fund that does not utilize leverage. An investment in the Fund is exposed to the risk that a decline in the weekly performance of shares of UBER will be magnified. This means that an investment in the Fund will be reduced by an amount equal to 1.2% for every 1% weekly decline in the market value of the UBER shares, not including the costs of financing leverage and other operating expenses, which would further reduce its value. The Fund could theoretically lose an amount greater than its net assets in the event the market value of UBER shares decline more than 83.33% over a calendar week. Leverage will also have the effect of magnifying any differences in the Fund’s correlation with UBER shares.

Roundhill UBER WeeklyPay™ ETF | MONEY MARKET INSTRUMENTS RISK  
Prospectus [Line Items]  
Risk [Text Block]

MONEY MARKET INSTRUMENTS RISK. The value of money market instruments may be affected by changing interest rates and by changes in the credit ratings of the investments. If a significant amount of the Fund’s assets are invested in money market instruments, it will be more difficult for the Fund to achieve its investment objectives. An investment in a money market fund is not insured or guaranteed by the FDIC or any other government agency. It is possible to lose money by investing in a money market fund.

Roundhill UBER WeeklyPay™ ETF | OPERATIONAL RISK  
Prospectus [Line Items]  
Risk [Text Block]

OPERATIONAL RISK. The Fund is subject to risks arising from various operational factors, including, but not limited to, human error, processing and communication errors, errors of the Fund’s service providers, counterparties or other third-parties, failed or inadequate processes and technology or systems failures. The Fund relies on third-parties for a range of services, including custody. Any delay or failure relating to engaging or maintaining such service providers may affect the Fund’s ability to meet its investment objectives. Although the Fund and the Adviser seek to reduce these operational risks through controls and procedures, there is no way to completely protect against such risks.

Roundhill UBER WeeklyPay™ ETF | SPECIAL TAX RISK  
Prospectus [Line Items]  
Risk [Text Block]

SPECIAL TAX RISK. The Fund intends to qualify annually and to elect to be treated as a regulated investment company under the Internal Revenue Code of 1986, as amended (the “Code”). To qualify for the favorable U.S. federal income tax treatment generally accorded to regulated investment companies, the Fund must, among other things, (i) derive in each taxable year at least 90% of its gross income from dividends, interest, payments with respect to securities loans and gains from the sale or other disposition of stock, securities or foreign currencies or other income derived with respect to its business of investing in such stock, securities or currencies, or net income derived from interests in certain publicly traded partnerships; (ii) diversify its holdings so that, at the end of each quarter of the taxable year, (a) at least 50% of the market value of the Fund’s assets is represented by cash and cash items (including receivables), U.S. government securities, the securities of other regulated investment companies and other securities, with such other securities of any one issuer generally limited for the purposes of this calculation to an amount not greater than 5% of the value of the Fund’s total assets and not greater than 10% of the outstanding voting securities of such issuer, and (b) not more than 25% of the value of its total assets is invested in the securities (other than U.S. government securities or the securities of other regulated investment companies) of any one issuer, or two or more issuers which the Fund controls which are engaged in the same, similar or related trades or businesses, or the securities of one or more of certain publicly traded partnerships; and (iii) distribute at least 90% of its investment company taxable income (which includes, among other items, dividends, interest and net short-term capital gains in excess of net long-term capital losses) and at least 90% of its net tax-exempt interest income each taxable year. There are certain exceptions for failure to qualify if the failure is for reasonable cause or is de minimis, and certain corrective action is taken and certain tax payments are made by the Fund.

 

The authority with regard to swaps entered into by regulated investment companies is unclear both as to the qualification under the income test and the identification of the issuer under the diversification test. The Fund intends to take the position that because the swaps held by the Fund reference securities that the income on the swaps are “other income” from the Fund’s business of investing in stocks and securities. In addition, the Fund intends to manage its investments in the swaps so that neither the exposure to issuer of the referenced security nor the exposure to any one counterparty of the swaps will exceed 25% of the gross value of the Fund’s portfolio at the end of any quarter.

 

If the Fund were to fail to meet the qualifying income test or asset diversification test and fail to qualify as a RIC, it would be taxed in the same manner as an ordinary corporation, and distributions to its shareholders would not be deductible by the Fund in computing its taxable income, which would adversely affect the Fund’s performance.

Roundhill UBER WeeklyPay™ ETF | STRUCTURAL ETF RISKS  
Prospectus [Line Items]  
Risk [Text Block]

STRUCTURAL ETF RISKS. The Fund is an ETF. Accordingly, it is subject to certain risks associated with its unique structure.

 

Market Participants Risk. Only an Authorized Participant may engage in creation or redemption transactions directly with the Fund, and none of those Authorized Participants is obligated to engage in creation and/or redemption transactions. The Fund has a limited number of institutions that may act as Authorized Participants on an agency basis (i.e., on behalf of other market participants). To the extent that Authorized Participants exit the business or are unable to proceed with creation or redemption orders with respect to the Fund and no other Authorized Participant is able to step forward to create or redeem, Fund Shares may be more likely to trade at a premium or discount to NAV and possibly face trading halts or delisting. The Fund may also rely on a small number of third-party market makers to provide a market for the purchase and sale of Fund Shares but such market makers are under no obligation to do so. Decisions by Authorized Participants or market makers to reduce their role or step away from these activities in times of market stress could inhibit the effectiveness of the arbitrage process in maintaining the relationship between the underlying values of the Fund’s portfolio securities and the Fund’s market price. Any trading halt or other problem relating to the trading activity of these market makers or any issues disrupting the Authorized Participants’ ability to proceed with creation and/or redemption orders could result in a dramatic change in the spread between the Fund’s net asset value and the price at which Fund Shares are trading on the Exchange, which could result in a decrease in value of Fund Shares. This reduced effectiveness could result in Fund Shares trading at a premium or discount to net asset value and also in greater than normal intraday bid-ask spreads Fund Shares.

 

Cash Transactions Risk. The Fund currently expects to effect a significant portion of its creations and redemptions for cash, rather than in-kind securities. Paying redemption proceeds in cash rather than through in-kind delivery of portfolio securities may require the Fund to dispose of or sell portfolio securities or other assets at an inopportune time to obtain the cash needed to meet redemption orders. This may cause the Fund to sell a security and recognize a capital gain or loss that might not have been incurred if it had made a redemption in-kind. As a result, the Fund may pay out higher or lower annual capital gains distributions than ETFs that redeem in-kind. The use of cash creations and redemptions may also cause the Fund’s Shares to trade in the market at greater bid-ask spreads or greater premiums or discounts to the Fund’s NAV. Furthermore, the Fund may not be able to execute cash transactions for creation and redemption purposes at the same price used to determine the Fund’s NAV. To the extent that the maximum additional charge for creation or redemption transactions is insufficient to cover the execution shortfall, the Fund’s performance could be negatively impacted.

 

Costs of Buying and Selling Fund Shares. Due to the costs of buying or selling Fund Shares, including brokerage commissions imposed by brokers and bid/ask spreads, frequent trading of Fund Shares may significantly reduce investment results and an investment in Fund Shares may not be advisable for investors who anticipate regularly making small investments.

 

Premium/Discount Risk. As with all ETFs, Fund Shares may be bought and sold in the secondary market at market prices. The trading prices of Fund Shares in the secondary market may differ from the Fund’s daily net asset value per share and there may be times when the market price of the shares is more than the net asset value per share (premium) or less than the net asset value per share (discount). If a shareholder purchases Fund Shares at a time when the market price is at a premium to the net asset value or sells Fund Shares at a time when the market price is at a discount to the net asset value, the shareholder may pay more for, or receive less than, the underlying value of the Fund Shares, respectively. This risk is heightened in times of market volatility or periods of steep market declines.

 

Trading Risks. Although Fund Shares are listed for trading on the Exchange and may be traded on U.S. exchanges other than the Exchange, there can be no assurance that Fund Shares will trade with any volume, or at all, on any stock exchange. In stressed market conditions, the liquidity of Fund Shares may begin to mirror the liquidity of the Fund’s underlying portfolio holdings, which can be significantly less liquid than Fund Shares. Trading in Fund Shares on the Exchange may be halted due to market conditions or for reasons that, in the view of the Exchange, make trading in Fund Shares inadvisable. In addition, trading in Fund Shares on the Exchange is subject to trading halts caused by extraordinary market volatility pursuant to the Exchange’s “circuit breaker” rules. There can be no assurance that the requirements of the Exchange necessary to maintain the listing of the Fund will continue to be met or will remain unchanged.

Roundhill UBER WeeklyPay™ ETF | U.S. GOVERNMENT SECURITIES RISK  
Prospectus [Line Items]  
Risk [Text Block]

U.S. GOVERNMENT SECURITIES RISK. U.S. government securities are subject to interest rate risk but generally do not involve the credit risks associated with investments in other types of debt securities. As a result, the yields available from U.S. government securities are generally lower than the yields available from other debt securities. U.S. government securities are guaranteed only as to the timely payment of interest and the payment of principal when held to maturity.

Roundhill UBER WeeklyPay™ ETF | VALUATION RISK  
Prospectus [Line Items]  
Risk [Text Block]

VALUATION RISK. The Fund may hold securities or other assets that may be valued on the basis of factors other than market quotations. This may occur because the asset or security does not trade on a centralized exchange, or in times of market turmoil or reduced liquidity. There are multiple methods that can be used to value a portfolio holding when market quotations are not readily available. The value established for any portfolio holding at a point in time might differ from what would be produced using a different methodology or if it had been priced using market quotations. Portfolio holdings that are valued using techniques other than market quotations, including “fair valued” assets or securities, may be subject to greater fluctuation in their valuations from one day to the next than if market quotations were used. In addition, there is no assurance that the Fund could sell or close out a portfolio position for the value established for it at any time, and it is possible that the Fund would incur a loss because a portfolio position is sold or closed out at a discount to the valuation established by the Fund at that time. The Fund’s ability to value investments may be impacted by technological issues or errors by pricing services or other third-party service providers.

Roundhill UBER WeeklyPay™ ETF | EQUITY SECURITIES RISK  
Prospectus [Line Items]  
Risk [Text Block]

EQUITY SECURITIES RISK. Equity securities are subject to changes in value, and their values may be more volatile than those of other asset classes. Equity securities prices fluctuate for several reasons, including changes in investors’ perceptions of the financial condition of an issuer or the general condition of the relevant equity market, such as market volatility, or when political or economic events affecting an issuer occur. Common stock prices may be particularly sensitive to rising interest rates, as the cost of capital rises and borrowing costs increase. Common stocks generally subject their holders to more risks than preferred stocks and debt securities because common stockholders’ claims are subordinated to those of holders of preferred stocks and debt securities upon the bankruptcy of the issuer.

Roundhill UBER WeeklyPay™ ETF | SWAP AGREEMENTS RISK  
Prospectus [Line Items]  
Risk [Text Block]

SWAP AGREEMENTS RISK. The Fund will utilize swap agreements to derive its exposure to shares of UBER. Swap agreements may involve greater risks than direct investment in securities as they may be leveraged and are subject to credit risk, counterparty risk and valuation risk. A swap agreement could result in losses if the underlying reference or asset does not perform as anticipated. In addition, many swaps trade over-the-counter and may be considered illiquid. It may not be possible for the Fund to liquidate a swap position at an advantageous time or price, which may result in significant losses.

Roundhill UBER WeeklyPay™ ETF | REGULATED INVESTMENT COMPANY TAX RISKS  
Prospectus [Line Items]  
Risk [Text Block]

REGULATED INVESTMENT COMPANY TAX RISKS. The Fund intends to qualify annually and to elect to be treated as a regulated investment company under the Internal Revenue Code of 1986, as amended (the “Code”). To qualify for the favorable U.S. federal income tax treatment generally accorded to regulated investment companies, the Fund must, among other things, (i) derive in each taxable year at least 90% of its gross income from dividends, interest, payments with respect to securities loans and gains from the sale or other disposition of stock, securities or foreign currencies or other income derived with respect to its business of investing in such stock, securities or currencies, or net income derived from interests in certain publicly traded partnerships; (ii) diversify its holdings so that, at the end of each quarter of the taxable year, (a) at least 50% of the market value of the Fund’s assets is represented by cash and cash items (including receivables), U.S. government securities, the securities of other regulated investment companies and other securities, with such other securities of any one issuer generally limited for the purposes of this calculation to an amount not greater than 5% of the value of the Fund’s total assets and not greater than 10% of the outstanding voting securities of such issuer, and (b) not more than 25% of the value of its total assets is invested in the securities (other than U.S. government securities or the securities of other regulated investment companies) of any one issuer, or two or more issuers which the Fund controls which are engaged in the same, similar or related trades or businesses, or the securities of one or more of certain publicly traded partnerships; and (iii) distribute at least 90% of its investment company taxable income (which includes, among other items, dividends, interest and net short-term capital gains in excess of net long-term capital losses) and at least 90% of its net tax-exempt interest income each taxable year. There are certain exceptions for failure to qualify if the failure is for reasonable cause or is de minimis, and certain corrective action is taken and certain tax payments are made by the Fund.

 

If the Fund were to fail to meet the qualifying income test or asset diversification test and fail to qualify as a RIC, it would be taxed in the same manner as an ordinary corporation, and distributions to its shareholders would not be deductible by the Fund in computing its taxable income, which would adversely affect the Fund’s performance.

Roundhill UBER WeeklyPay™ ETF | LARGE SHAREHOLDER RISK  
Prospectus [Line Items]  
Risk [Text Block]

LARGE SHAREHOLDER RISK. Certain shareholders, including affiliated funds advised by the Adviser, may from time to time own a significant portion of the Fund’s shares. In addition, a third-party investor, the Adviser or an affiliate of the Adviser (“Affiliate”), an authorized participant, a market maker, or another entity may invest in the Fund and hold its investment for a limited period solely to facilitate the commencement of the Fund or to help the Fund achieve a specified size or scale. There can be no assurance that any large shareholder will not redeem its investment, that the size of the Fund will be maintained at such levels, or that the Fund will continue to meet applicable listing requirements. Redemptions by large shareholders could have a significant negative impact on the Fund. In addition, transactions by large shareholders may account for a large percentage of the trading volume on the Fund’s listing exchange and may, therefore, have a material upward or downward effect on the market price of the shares.

 

To the extent that a significant percentage of the Fund’s shares are owned or controlled by a small number of account shareholders (or a single account shareholder), including funds or accounts over which the Adviser or an Affiliate has investment discretion, the Fund is subject to the risk that those shareholders may purchase or redeem Fund shares in significant amounts rapidly or unexpectedly, including as a result of an asset allocation decision made by the Adviser or an Affiliate. This may adversely affect the Fund’s performance if the Adviser is forced to sell portfolio securities or invest cash when it would not otherwise choose to do so. Redemptions of a large number of shares may affect the liquidity of the Fund’s portfolio, increase the Fund’s transaction costs, and accelerate the realization of taxable income and/or gains. In addition, a large redemption could result in the Fund’s current expenses being allocated over a smaller asset base, leading to an increase in the Fund’s gross expense ratio. Large purchases of the Fund’s shares may also adversely affect the Fund’s performance to the extent that the Fund is delayed in investing new cash or otherwise maintains a larger cash position than it ordinarily would, particularly if the Fund accepts cash for an order for the purchase of creation units of the Fund’s shares.

Roundhill UBER WeeklyPay™ ETF | UBER INVESTING RISKS  
Prospectus [Line Items]  
Risk [Text Block]

UBER INVESTING RISKS. The Fund will have significant exposure to UBER through its investments in swap agreements that utilize UBER as the reference asset. Accordingly, the Fund will subject to the risks of UBER, set forth below.

 

UBER ISSUER-SPECIFIC RISKS. Issuer-specific attributes may cause an investment held by the Fund to be more volatile than the market generally. The value of an individual security or particular type of security may be more volatile than the market as a whole and may perform differently from the value of the market as a whole. UBER faces strong competition from other ride-sharing companies, local taxi services, and public transportation. Increased competition could lead to pricing pressure, driver shortages, and customer acquisition costs. UBER has historically prioritized growth over profitability, and while it has made strides toward positive cash flow, sustained profitability remains a challenge due to high operating costs and driver incentives. Higher fuel prices, labor costs, and insurance premiums could squeeze UBER’s margins, particularly if the company is unable to pass these costs onto consumers without affecting demand. UBER’s revenue is closely tied to consumer spending and travel activity. Economic downturns, recessions, or reductions in business travel could lead to a decline in rides and delivery orders. UBER has faced passenger and driver safety concerns, including lawsuits related to driver background checks and incidents of misconduct. Negative publicity could damage brand reputation and reduce ridership. UBER’s business model relies on independent contractors (drivers and couriers). Regulatory changes in worker classification – such as efforts to classify drivers as employees rather than independent contractors – could significantly increase costs related to wages, benefits, and compliance. UBER operates in multiple jurisdictions, each with different transportation, safety, and licensing laws. Stricter regulations, city-level bans, or additional fees could impact its ability to operate profitably in key markets. UBER faces ongoing lawsuits related to antitrust issues, passenger safety, driver treatment, and competitive practices. Any adverse rulings or settlements could result in financial penalties and reputational harm.

 

INDIRECT INVESTMENT RISK. Uber Technologies, Inc. is not affiliated with the Trust, the Fund, the Adviser, the Sub-Adviser or any affiliates thereof and is not involved with this offering in any way, and has no obligation to consider the Fund in taking any corporate actions that might affect the value of the Fund. The Trust, the Fund, the Adviser, the Sub-Adviser or any affiliate are not responsible for the performance of UBER and make no representation as to the performance of UBER. Investing in the Fund is not equivalent to investing in UBER. Fund shareholders will not have voting rights or rights to receive dividends or other distributions or any other rights with respect to UBER.

 

INDUSTRIALS COMPANIES RISK. Industrials companies convert unfinished goods into finished durables used to manufacture other goods or provide services. Examples of industrials companies include companies involved in the production of electrical equipment and components, industrial products, manufactured housing and telecommunications equipment, as well as defense and aerospace companies. General risks of industrials companies include the general state of the economy, exchange rates, commodity prices, intense competition, consolidation, domestic and international politics, government regulation, import controls, excess capacity, consumer demand and spending trends. In addition, industrials companies may also be significantly affected by overall capital spending levels, economic cycles, rapid technical changes, delays in modernization, labor relations, environmental liabilities, governmental and product liability and e-commerce initiatives.

 

LARGE CAPITALIZATION COMPANIES RISK. Large capitalization companies may be less able than smaller capitalization companies to adapt to changing market conditions. Large capitalization companies may be more mature and subject to more limited growth potential compared with smaller capitalization companies. During different market cycles, the performance of large capitalization companies has trailed the overall performance of the broader securities markets.

 

TRANSPORTATION COMPANIES RISK. Transportation companies may be adversely affected by changes in the economy, volatility in energy prices, labor relations, business interruptions, supply chain disruptions, trade disputes, technology developments, exchange rates, insurance costs and government regulation. Transportation companies are also affected by natural disasters, environmental incidents, terrorism, war and other events that target or damage transportation infrastructure. As a result of such events, insurance premiums and other operating costs may increase significantly, and insurance coverage may become unavailable. Securities of transportation companies are generally cyclical and may be subject to sharp price movements.

 

UNITED STATES RISK. Certain changes in the U.S. economy, such as when the U.S. economy weakens or when its financial markets decline, may have an adverse effect on the securities to which the Fund has exposure.

NON-DIVERSIFICATION RISK. As a “non-diversified” fund, the Fund may hold a smaller number of portfolio securities than many other funds. To the extent the Fund invests in a relatively small number of issuers, a decline in the market value of a particular security held by the Fund may affect its value more than if it invested in a larger number of issuers. The value of the Fund Shares may be more volatile than the values of shares of more diversified funds.

Roundhill MSTR WeeklyPay™ ETF | MARKET RISK  
Prospectus [Line Items]  
Risk [Text Block]

MARKET RISK. Market risk is the risk that a particular investment, or Fund Shares in general, may fall in value. Securities are subject to market fluctuations caused by real or perceived adverse economic, political, and regulatory factors or market developments, changes in interest rates, disruptions to trade, impositions of tariffs and perceived trends in securities prices. Fund Shares could decline in value or underperform other investments. In addition, local, regional or global events such as war, acts of terrorism, market manipulation, government defaults, government shutdowns, regulatory actions, political changes, diplomatic developments, the imposition of sanctions and other similar measures, spread of infectious diseases or other public health issues, recessions, natural disasters, or other events could have a significant negative impact on the Fund and its investments. Any of such circumstances could have a materially negative impact on the value of Fund Shares, the liquidity of an investment, and may result in increased market volatility. During any such events, Fund Shares may trade at increased premiums or discounts to their net asset value, the bid/ask spread on Fund Shares may widen and the returns on investment may fluctuate.

Roundhill MSTR WeeklyPay™ ETF | OPTIONS RISK  
Prospectus [Line Items]  
Risk [Text Block]

OPTIONS RISK. The use of options involves investment strategies and risks different from those associated with ordinary portfolio securities transactions and depends on the ability of the Fund’s portfolio managers to forecast market movements correctly. The prices of options are volatile and are influenced by, among other things, actual and anticipated changes in the value of the underlying instrument, or in interest or currency exchange rates, including the anticipated volatility, which in turn are affected by fiscal and monetary policies and by national and international political and economic events. The effective use of options also depends on the Fund’s ability to terminate option positions at times deemed desirable to do so. There is no assurance that the Fund will be able to effect closing transactions at any particular time or at an acceptable price. In addition, there may at times be an imperfect correlation between the movement in values of options and their underlying securities and there may at times not be a liquid secondary market for certain options. Lastly, the trading of options is subject to transaction costs that may impact the Fund’s returns.

Roundhill MSTR WeeklyPay™ ETF | LIQUIDITY RISK  
Prospectus [Line Items]  
Risk [Text Block]

LIQUIDITY RISK. The market for swap agreements that reference MSTR shares may be subject to periods of illiquidity. During such times it may be difficult or impossible to buy or sell a position at the desired price. Market disruptions or volatility can also make it difficult to find a counterparty willing to transact at a reasonable price and sufficient size. Illiquid markets may cause losses, which could be significant. The large size of the positions which the Fund may acquire increases the risk of illiquidity, may make its positions more difficult to liquidate, and may increase the losses incurred while trying to do so. Such large positions also may impact the price of swap agreements on MSTR shares.

Roundhill MSTR WeeklyPay™ ETF | ACTIVE MANAGEMENT RISK  
Prospectus [Line Items]  
Risk [Text Block]

ACTIVE MANAGEMENT RISK. The Fund is actively-managed and its performance reflects investment decisions that the Adviser and/or Sub-Adviser makes for the Fund. Such judgments about the Fund’s investments may prove to be incorrect. If the investments selected and the strategies employed by the Fund fail to produce the intended results, the Fund could underperform as compared to other funds with similar investment objectives and/or strategies, or could have negative returns.

Roundhill MSTR WeeklyPay™ ETF | ACTIVE MARKET RISK

ACTIVE MARKET RISK. Although Fund Shares are listed for trading on the Exchange, there can be no assurance that an active trading market for Fund Shares will develop or be maintained. Fund Shares trade on the Exchange at market prices that may be below, at or above the Fund’s net asset value. Securities, including Fund Shares, are subject to market fluctuations and liquidity constraints that may be caused by such factors as economic, political, or regulatory developments, changes in interest rates, and/or perceived trends in securities prices. Fund Shares could decline in value or underperform other investments.

ASSET CLASS RISK. Securities and other assets in the Fund’s portfolio may underperform in comparison to the general financial markets, a particular financial market or other asset classes.

Roundhill MSTR WeeklyPay™ ETF | CLEARING MEMBER DEFAULT RISK  
Prospectus [Line Items]  
Risk [Text Block]

CLEARING MEMBER DEFAULT RISK. Transactions in some types of derivatives, including the options held by the Fund, are required to be centrally cleared (“cleared derivatives”). In a transaction involving cleared derivatives, the Fund’s counterparty is a clearinghouse, such as the OCC, rather than a bank or broker. Since the Fund is not a member of clearinghouses, and only members of a clearinghouse (“clearing members”) can participate directly in the clearinghouse, the Fund will hold cleared derivatives through accounts at clearing members. With regard its cleared derivatives positions, the Fund will make payments (including margin payments) to, and receive payments from, a clearinghouse through their accounts at clearing members. Customer funds held at a clearing organization in connection with any option contracts are held in a commingled omnibus account and are not identified to the name of the clearing member’s individual customers. As a result, assets deposited by the Fund with any clearing member as margin for its options position may, in certain circumstances, be used to satisfy losses of other clients of the Fund’s clearing member. In addition, although clearing members guarantee performance of their clients’ obligations to the clearinghouse, there is a risk that the assets of the Fund might not be fully protected in the event of the clearing member’s bankruptcy. The Fund is also subject to the risk that a limited number of clearing members are willing to transact on the Fund’s behalf, which heightens the risks associated with a clearing member’s default. If a clearing member defaults, the Fund could lose some or all of the benefits of a transaction entered into by the Fund with the clearing member. The loss of a clearing member for the Fund to transact with could result in increased transaction costs and other operational issues that could impede the Fund’s ability to implement its investment strategy. If the Fund cannot find a clearing member to transact with on the Fund’s behalf, the Fund may be unable to effectively implement its investment strategy.

Roundhill MSTR WeeklyPay™ ETF | CONCENTRATION RISK

Risk [Text Block]

CONCENTRATION RISK. The Fund is susceptible to an increased risk of loss, including losses due to adverse events that affect the Fund’s investments more than the market as a whole, to the extent that the Fund’s investments are concentrated in investments that provide exposure to MSTR and the industry to which it is assigned.

Roundhill MSTR WeeklyPay™ ETF | COUNTERPARTY RISK  
Prospectus [Line Items]  
Risk [Text Block]

COUNTERPARTY RISK. Fund transactions involving a counterparty are subject to the risk that the counterparty will not fulfill its obligation to the Fund. Counterparty risk may arise because of the counterparty’s financial condition (i.e., financial difficulties, bankruptcy, or insolvency), market activities and developments, or other reasons, whether foreseen or not. A counterparty’s inability to fulfill its obligation may result in significant financial loss to the Fund. The Fund may be unable to recover its investment from the counterparty or may obtain a limited recovery, and/or recovery may be delayed.

CREDIT RISK. An issuer or other obligated party of a debt security may be unable or unwilling to make dividend, interest and/or principal payments when due. In addition, the value of a debt security may decline because of concerns about the issuer’s ability or unwillingness to make such payments.

Roundhill MSTR WeeklyPay™ ETF | CURRENT MARKET CONDITIONS RISK  
Prospectus [Line Items]  
Risk [Text Block]

CURRENT MARKET CONDITIONS RISK. Current market conditions risk is the risk that a particular investment, or Fund Shares in general, may fall in value due to current market conditions. As a means to fight inflation, which remains at elevated levels, the Federal Reserve and certain foreign central banks have raised interest rates; however, the Federal Reserve has recently lowered interest rates and may continue to do so. U.S. regulators have proposed several changes to market and issuer regulations which would directly impact the Fund, and any regulatory changes could adversely impact the Fund’s ability to achieve its investment strategies or make certain investments. Recent and potential future bank failures could result in disruption to the broader banking industry or markets generally and reduce confidence in financial institutions and the economy as a whole, which may also heighten market volatility and reduce liquidity. Additionally, challenges in commercial real estate markets, including rising interest rates, declining valuations and increasing vacancies, could have a broader impact on financial markets. The ongoing adversarial political climate in the United States, as well as political and diplomatic events both domestic and abroad, have and may continue to have an adverse impact the U.S. regulatory landscape, markets and investor behavior, which could have a negative impact on the Fund’s investments and operations. The change in administration resulting from the 2024 United States national elections could result in significant impacts to international trade relations, tax and immigration policies, and other aspects of the national and international political and financial landscape, which could affect, among other things, inflation and the securities markets generally. Other unexpected political, regulatory and diplomatic events within the U.S. and abroad may affect investor and consumer confidence and may adversely impact financial markets and the broader economy. For example, ongoing armed conflicts between Russia and Ukraine in Europe and among Israel, Iran, Hamas and other militant groups in the Middle East, have caused and could continue to cause significant market disruptions and volatility within the markets in Russia, Europe, the Middle East and the United States. The hostilities and sanctions resulting from those hostilities have and could continue to have a significant impact on certain Fund investments as well as Fund performance and liquidity. The economies of the United States and its trading partners, as well as the financial markets generally, may be adversely impacted by trade disputes, including the imposition of tariffs, and other matters. For example, the United States has imposed trade barriers and restrictions on China. In addition, the Chinese government is engaged in a longstanding dispute with Taiwan, continually threatening an invasion. If the political climate between the United States and China does not improve or continues to deteriorate, if China were to attempt invading Taiwan, or if other geopolitical conflicts develop or worsen, economies, markets and individual securities may be adversely affected, and the value of the Fund’s assets may go down. A public health crisis and the ensuing policies enacted by governments and central banks may cause significant volatility and uncertainty in global financial markets, negatively impacting global growth prospects. As the COVID-19 global pandemic illustrated, such events may affect certain geographic regions, countries, sectors and industries more significantly than others. Advancements in technology may also adversely impact markets and the overall performance of the Fund. For instance, the economy may be significantly impacted by the advanced development and increased regulation of artificial intelligence. Additionally, cyber security breaches of both government and non-government entities could have negative impacts on infrastructure and the ability of such entities, including the Fund, to operate properly. These events, and any other future events, may adversely affect the prices and liquidity of the Fund’s portfolio investments and could result in disruptions in the trading markets.

Roundhill MSTR WeeklyPay™ ETF | CYBERSECURITY RISK  
Prospectus [Line Items]  
Risk [Text Block]

CYBERSECURITY RISK. Failures or breaches of the electronic systems of the Fund, the Fund’s adviser, sub-adviser, distributor and other service providers, market makers, Authorized Participants or the issuers of securities in which the Fund invests have the ability to cause disruptions, negatively impact the Fund’s business operations and/or potentially result in financial losses to the Fund and its shareholders. While the Fund has established business continuity plans and risk management systems seeking to address system breaches or failures, there are inherent limitations in such plans and systems. Furthermore, the Fund cannot control the cybersecurity plans and systems of the Fund’s other service providers, market makers, Authorized Participants or issuers of securities in which the Fund invests.

Roundhill MSTR WeeklyPay™ ETF | DEBT SECURITIES RISK  
Prospectus [Line Items]  
Risk [Text Block]

DEBT SECURITIES RISK. Investments in debt securities subject the holder to the credit risk of the issuer. Credit risk refers to the possibility that the issuer or other obligor of a security will not be able or willing to make payments of interest and principal when due. Generally, the value of debt securities will change inversely with changes in interest rates. To the extent that interest rates rise, certain underlying obligations may be paid off substantially slower than originally anticipated and the value of those securities may fall sharply. During periods of falling interest rates, the income received by the Fund may decline. If the principal on a debt security is prepaid before expected, the prepayments of principal may have to be reinvested in obligations paying interest at lower rates. Debt securities generally do not trade on a securities exchange making them generally less liquid and more difficult to value than common stock.

Roundhill MSTR WeeklyPay™ ETF | DERIVATIVES RISK  
Prospectus [Line Items]  
Risk [Text Block]

DERIVATIVES RISK. The use of derivative instruments involves risks different from, or possibly greater than, the risks associated with investing directly in securities and other traditional investments. These risks include: (i) the risk that the counterparty to a derivative transaction may not fulfill its contractual obligations; (ii) risk of mispricing or improper valuation; and (iii) the risk that changes in the value of the derivative may not correlate perfectly with the underlying asset. Derivative prices are highly volatile and may fluctuate substantially during a short period of time. Such prices are influenced by numerous factors that affect the markets, including, but not limited to: changing supply and demand relationships; government programs and policies; national and international political and economic events, changes in interest rates, inflation and deflation and changes in supply and demand relationships. Trading derivative instruments involves risks different from, or possibly greater than, the risks associated with investing directly in securities. Derivative contracts ordinarily have leverage inherent in their terms. The use of leverage may cause the Fund to liquidate portfolio positions when it would not be advantageous to do so in order to satisfy its obligations or to meet regulatory or contractual requirements for derivatives. The use of derivatives can magnify potential for gain or loss and, therefore, amplify the effects of market volatility on share price.

Roundhill MSTR WeeklyPay™ ETF | DISTRIBUTION TAX RISK  
Prospectus [Line Items]  
Risk [Text Block]

DISTRIBUTION TAX RISK. The Fund currently expects to make distributions on a weekly basis. Such frequent distributions may expose investors to increased tax liabilities. However, these distributions may exceed the Fund’s income and gains for the Fund’s taxable year. Distributions in excess of the Fund’s current and accumulated earnings and profits will be treated as a return of capital. A return of capital distribution generally will not be taxable but will reduce the shareholder’s cost basis and will result in a higher capital gain or lower capital loss when those Fund Shares on which the distribution was received are sold. Once the Fund shareholder’s cost basis is reduced to zero, further distributions will be treated as capital gain if the Fund shareholder holds Fund Shares as capital assets. Additionally, any capital returned through distributions will be distributed after payment of Fund fees and expenses. Because a portion of the Fund’s distributions may consist of return of capital, the Fund may not be an appropriate investment for investors who do not want their principal investment in the Fund to decrease over time or who do not wish to receive return of capital in a given period. In the event that a shareholder purchases Fund Shares shortly before a distribution by the Fund, the entire distribution may be taxable to the shareholder even though a portion of the distribution effectively represents a return of the purchase price.

Roundhill MSTR WeeklyPay™ ETF | ETF RISK  
Prospectus [Line Items]  
Risk [Text Block]

ETF RISK. The Fund may invest in ETFs. The value of an ETF held by the Fund will fluctuate over time based on fluctuations in the values of the assets held by the ETF, which may be affected by changes in general economic conditions, expectations for future growth and profits, interest rates and the supply and demand for those assets. When the Fund invests in an ETF, it will bear a proportionate share of the ETF’s expenses. Brokerage, tax and other expenses may negatively impact the performance of the ETF and, in turn, the value of Fund Shares. An ETF that tracks an index may not exactly match the performance of the index due to cash drag, differences between the portfolio of the ETF and the components of the index, expenses and other factors.

Roundhill MSTR WeeklyPay™ ETF | FLEX OPTIONS RISK  
Prospectus [Line Items]  
Risk [Text Block]

FLEX OPTIONS RISK. The Fund will utilize FLEX Options to derive exposure to shares of MSTR. Trading FLEX Options involves risks different from, or possibly greater than, the risks associated with investing directly in securities. The Fund may experience losses from specific FLEX Option positions and certain FLEX Option positions may expire worthless. The FLEX Options are listed on an exchange; however, no one can guarantee that a liquid secondary trading market will exist for the FLEX Options. In the event that trading in the FLEX Options is limited or absent, the value of the Fund’s FLEX Options may decrease. In a less liquid market for the FLEX Options, liquidating the FLEX Options may require the payment of a premium (for written FLEX Options) or acceptance of a discounted price (for purchased FLEX Options) and may take longer to complete. A less liquid trading market may adversely impact the value of the FLEX Options and Fund shares and result in the Fund being unable to achieve its investment objectives. Less liquidity in the trading of the Fund’s FLEX Options could have an impact on the prices paid or received by the Fund for the FLEX Options in connection with creations and redemptions of the Fund’s shares. Depending on the nature of this impact to pricing, the Fund may be forced to pay more for redemptions (or receive less for creations) than the price at which it currently values the FLEX Options. Such overpayment or under collection could reduce the Fund’s ability to achieve its investment objectives. Additionally, in a less liquid market for the FLEX Options, the liquidation of a large number of options may more significantly impact the price. A less liquid trading market may adversely impact the value of the FLEX Options and the value of your investment. The trading in FLEX Options may be less deep and liquid than the market for certain other exchange-traded options, non-customized options or other securities.

Roundhill MSTR WeeklyPay™ ETF | INFLATION RISK  
Prospectus [Line Items]  
Risk [Text Block]

INFLATION RISK. Inflation risk is the risk that the value of assets or income from investments will be less in the future as inflation decreases the value of money. As inflation increases, the present value of the Fund’s assets and distributions may decline. This risk is more prevalent with respect to fixed income securities held by the Fund.

Roundhill MSTR WeeklyPay™ ETF | Interest Rate Risk [Member]  
Prospectus [Line Items]  
Risk [Text Block]

INTEREST RATE RISK. Interest rate risk is the risk that the value of the debt securities in the Fund’s portfolio will decline because of rising market interest rates. Interest rate risk is generally lower for shorter term debt securities and higher for longer-term debt securities. Duration is a reasonably accurate measure of a debt security’s price sensitivity to changes in interest rates and a common measure of interest rate risk. Duration measures a debt security’s expected life on a present value basis, taking into account the debt security’s yield, interest payments and final maturity. In general, duration represents the expected percentage change in the value of a security for an immediate 1% change in interest rates. For example, the price of a debt security with a three-year duration would be expected to drop by approximately 3% in response to a 1% increase in interest rates. Therefore, prices of debt securities with shorter durations tend to be less sensitive to interest rate changes than debt securities with longer durations. As the value of a debt security changes over time, so will its duration.

Roundhill MSTR WeeklyPay™ ETF | LEGISLATION AND LITIGATION RISK  
Prospectus [Line Items]  
Risk [Text Block]

LEGISLATION AND LITIGATION RISK. Legislation or litigation that affects the value of assets or securities held by the Fund may reduce the value of the Fund. From time to time, various legislative initiatives are proposed that may have a negative impact on certain assets or securities in which the Fund invests. In addition, litigation regarding any of the assets or securities owned by the Fund may negatively impact the value of Fund Shares. Such legislation or litigation may cause the Fund to lose value or may result in higher portfolio turnover if the Adviser determines to sell such a holding.

Roundhill MSTR WeeklyPay™ ETF | LEVERAGE RISK  
Prospectus [Line Items]  
Risk [Text Block]

LEVERAGE RISK. The Fund obtains investment exposure in excess of its net assets by utilizing leverage and may lose more money in market conditions that are adverse to its investment objectives than a fund that does not utilize leverage. An investment in the Fund is exposed to the risk that a decline in the weekly performance of shares of MSTR will be magnified. This means that an investment in the Fund will be reduced by an amount equal to 1.2% for every 1% weekly decline in the market value of the MSTR shares, not including the costs of financing leverage and other operating expenses, which would further reduce its value. The Fund could theoretically lose an amount greater than its net assets in the event the market value of MSTR shares decline more than 83.33% over a calendar week. Leverage will also have the effect of magnifying any differences in the Fund’s correlation with MSTR shares.

Roundhill MSTR WeeklyPay™ ETF | MONEY MARKET INSTRUMENTS RISK  
Prospectus [Line Items]  
Risk [Text Block]

MONEY MARKET INSTRUMENTS RISK. The value of money market instruments may be affected by changing interest rates and by changes in the credit ratings of the investments. If a significant amount of the Fund’s assets are invested in money market instruments, it will be more difficult for the Fund to achieve its investment objectives. An investment in a money market fund is not insured or guaranteed by the FDIC or any other government agency. It is possible to lose money by investing in a money market fund.

Roundhill MSTR WeeklyPay™ ETF | OPERATIONAL RISK  
Prospectus [Line Items]  
Risk [Text Block]

OPERATIONAL RISK. The Fund is subject to risks arising from various operational factors, including, but not limited to, human error, processing and communication errors, errors of the Fund’s service providers, counterparties or other third-parties, failed or inadequate processes and technology or systems failures. The Fund relies on third-parties for a range of services, including custody. Any delay or failure relating to engaging or maintaining such service providers may affect the Fund’s ability to meet its investment objectives. Although the Fund and the Adviser seek to reduce these operational risks through controls and procedures, there is no way to completely protect against such risks.

Roundhill MSTR WeeklyPay™ ETF | REVERSE REPURCHASE AGREEMENTS RISK  
Prospectus [Line Items]  
Risk [Text Block]

REVERSE REPURCHASE AGREEMENTS RISK. Reverse repurchase agreements involve both counterparty risk and the risk that the value of securities that the Fund is obligated to repurchase under the agreement may decline below the repurchase price. Reverse repurchase agreements involve leverage risk; the Fund may lose money as a result of declines in the values both of the security subject to the reverse repurchase agreement and the instruments in which the Fund invested the proceeds of the reverse repurchase agreement.

Roundhill MSTR WeeklyPay™ ETF | SPECIAL TAX RISK  
Prospectus [Line Items]  
Risk [Text Block]

SPECIAL TAX RISK. The Fund intends to qualify annually and to elect to be treated as a regulated investment company under the Code. To qualify for the favorable U.S. federal income tax treatment generally accorded to regulated investment companies, the Fund must, among other things, (i) derive in each taxable year at least 90% of its gross income from dividends, interest, payments with respect to securities loans and gains from the sale or other disposition of stock, securities or foreign currencies or other income derived with respect to its business of investing in such stock, securities or currencies, or net income derived from interests in certain publicly traded partnerships; (ii) diversify its holdings so that, at the end of each quarter of the taxable year, (a) at least 50% of the market value of the Fund’s assets is represented by cash and cash items (including receivables), U.S. government securities, the securities of other regulated investment companies and other securities, with such other securities of any one issuer generally limited for the purposes of this calculation to an amount not greater than 5% of the value of the Fund’s total assets and not greater than 10% of the outstanding voting securities of such issuer, and (b) not more than 25% of the value of its total assets is invested in the securities (other than U.S. government securities or the securities of other regulated investment companies) of any one issuer, or two or more issuers which the Fund controls which are engaged in the same, similar or related trades or businesses, or the securities of one or more of certain publicly traded partnerships; and (iii) distribute at least 90% of its investment company taxable income (which includes, among other items, dividends, interest and net short-term capital gains in excess of net long-term capital losses) and at least 90% of its net tax-exempt interest income each taxable year. There are certain exceptions for failure to qualify if the failure is for reasonable cause or is de minimis, and certain corrective action is taken and certain tax payments are made by the Fund.

 

The authority with regard to swaps entered into by regulated investment companies is unclear both as to the qualification under the income test and the identification of the issuer under the diversification test. The Fund intends to take the position that because the swaps held by the Fund reference securities that the income on the swaps are “other income” from the Fund’s business of investing in stocks and securities. In addition, the Fund intends to manage its investments in the swaps so that neither the exposure to issuer of the referenced security nor the exposure to any one counterparty of the swaps will exceed 25% of the gross value of the Fund’s portfolio at the end of any quarter.

 

If the Fund were to fail to meet the qualifying income test or asset diversification test and fail to qualify as a RIC, it would be taxed in the same manner as an ordinary corporation, and distributions to its shareholders would not be deductible by the Fund in computing its taxable income, which would adversely affect the Fund’s performance.

Roundhill MSTR WeeklyPay™ ETF | STRUCTURAL ETF RISKS  
Prospectus [Line Items]  
Risk [Text Block]

STRUCTURAL ETF RISKS. The Fund is an ETF. Accordingly, it is subject to certain risks associated with its unique structure.

 

Market Participants Risk. Only an Authorized Participant may engage in creation or redemption transactions directly with the Fund, and none of those Authorized Participants is obligated to engage in creation and/or redemption transactions. The Fund has a limited number of institutions that may act as Authorized Participants on an agency basis (i.e., on behalf of other market participants). To the extent that Authorized Participants exit the business or are unable to proceed with creation or redemption orders with respect to the Fund and no other Authorized Participant is able to step forward to create or redeem, Fund Shares may be more likely to trade at a premium or discount to NAV and possibly face trading halts or delisting. The Fund may also rely on a small number of third-party market makers to provide a market for the purchase and sale of Fund Shares but such market makers are under no obligation to do so. Decisions by Authorized Participants or market makers to reduce their role or step away from these activities in times of market stress could inhibit the effectiveness of the arbitrage process in maintaining the relationship between the underlying values of the Fund’s portfolio securities and the Fund’s market price. Any trading halt or other problem relating to the trading activity of these market makers or any issues disrupting the Authorized Participants’ ability to proceed with creation and/or redemption orders could result in a dramatic change in the spread between the Fund’s net asset value and the price at which Fund Shares are trading on the Exchange, which could result in a decrease in value of Fund Shares. This reduced effectiveness could result in Fund Shares trading at a premium or discount to net asset value and also in greater than normal intraday bid-ask spreads Fund Shares.

 

Cash Transactions Risk. The Fund currently expects to effect a significant portion of its creations and redemptions for cash, rather than in-kind securities. Paying redemption proceeds in cash rather than through in-kind delivery of portfolio securities may require the Fund to dispose of or sell portfolio securities or other assets at an inopportune time to obtain the cash needed to meet redemption orders. This may cause the Fund to sell a security and recognize a capital gain or loss that might not have been incurred if it had made a redemption in-kind. As a result, the Fund may pay out higher or lower annual capital gains distributions than ETFs that redeem in-kind. The use of cash creations and redemptions may also cause the Fund’s Shares to trade in the market at greater bid-ask spreads or greater premiums or discounts to the Fund’s NAV. Furthermore, the Fund may not be able to execute cash transactions for creation and redemption purposes at the same price used to determine the Fund’s NAV. To the extent that the maximum additional charge for creation or redemption transactions is insufficient to cover the execution shortfall, the Fund’s performance could be negatively impacted.

 

Costs of Buying and Selling Fund Shares. Due to the costs of buying or selling Fund Shares, including brokerage commissions imposed by brokers and bid/ask spreads, frequent trading of Fund Shares may significantly reduce investment results and an investment in Fund Shares may not be advisable for investors who anticipate regularly making small investments.

 

Premium/Discount Risk. As with all ETFs, Fund Shares may be bought and sold in the secondary market at market prices. The trading prices of Fund Shares in the secondary market may differ from the Fund’s daily NAV per Fund Share and there may be times when the market price of the Fund Shares is more than the NAV per Fund Share (premium) or less than the NAV per Fund Share (discount). If a shareholder purchases Fund Shares at a time when the market price is at a premium to the NAV or sells Fund Shares at a time when the market price is at a discount to the NAV, the shareholder may pay more for, or receive less than, the underlying value of Fund Shares, respectively. This risk is heightened in times of market volatility or periods of steep market declines.

 

Trading Risks. Although Fund Shares are listed for trading on the Exchange and may be traded on U.S. exchanges other than the Exchange, there can be no assurance that Fund Shares will trade with any volume, or at all, on any stock exchange. In stressed market conditions, the liquidity of Fund Shares may begin to mirror the liquidity of the Fund’s underlying portfolio holdings, which can be significantly less liquid than Fund Shares. Trading in Fund Shares on the Exchange may be halted due to market conditions or for reasons that, in the view of the Exchange, make trading in Fund Shares inadvisable. In addition, trading in Fund Shares on the Exchange is subject to trading halts caused by extraordinary market volatility pursuant to the Exchange’s “circuit breaker” rules. There can be no assurance that the requirements of the Exchange necessary to maintain the listing of the Fund will continue to be met or will remain unchanged.

Roundhill MSTR WeeklyPay™ ETF | VALUATION RISK  
Prospectus [Line Items]  
Risk [Text Block]

VALUATION RISK. The Fund may hold securities or other assets that may be valued on the basis of factors other than market quotations. This may occur because the asset or security does not trade on a centralized exchange, or in times of market turmoil or reduced liquidity. There are multiple methods that can be used to value a portfolio holding when market quotations are not readily available. The value established for any portfolio holding at a point in time might differ from what would be produced using a different methodology or if it had been priced using market quotations. Portfolio holdings that are valued using techniques other than market quotations, including “fair valued” assets or securities, may be subject to greater fluctuation in their valuations from one day to the next than if market quotations were used. In addition, there is no assurance that the Fund could sell or close out a portfolio position for the value established for it at any time, and it is possible that the Fund would incur a loss because a portfolio position is sold or closed out at a discount to the valuation established by the Fund at that time. The Fund’s ability to value investments may be impacted by technological issues or errors by pricing services or other third-party service providers.

Roundhill MSTR WeeklyPay™ ETF | EQUITY SECURITIES RISK  
Prospectus [Line Items]  
Risk [Text Block]

EQUITY SECURITIES RISK. Equity securities are subject to changes in value, and their values may be more volatile than those of other asset classes. Equity securities prices fluctuate for several reasons, including changes in investors’ perceptions of the financial condition of an issuer or the general condition of the relevant equity market, such as market volatility, or when political or economic events affecting an issuer occur. Common stock prices may be particularly sensitive to rising interest rates, as the cost of capital rises and borrowing costs increase. Common stocks generally subject their holders to more risks than preferred stocks and debt securities because common stockholders’ claims are subordinated to those of holders of preferred stocks and debt securities upon the bankruptcy of the issuer.

Roundhill MSTR WeeklyPay™ ETF | PORTFOLIO TURNOVER RISK  
Prospectus [Line Items]

PORTFOLIO TURNOVER RISK. High portfolio turnover may result in the Fund paying higher levels of transaction costs and may generate greater tax liabilities for shareholders. Portfolio turnover risk may cause the Fund’s performance to be less than expected.

Roundhill MSTR WeeklyPay™ ETF | SWAP AGREEMENTS RISK  
Prospectus [Line Items]  
Risk [Text Block]

SWAP AGREEMENTS RISK. The Fund will utilize swap agreements to derive exposure to shares of MSTR. Swap agreements may involve greater risks than direct investment in securities as they may be leveraged and are subject to credit risk, counterparty risk and valuation risk. A swap agreement could result in losses if the underlying reference or asset does not perform as anticipated. In addition, many swaps trade over-the-counter and may be considered illiquid. It may not be possible for the Fund to liquidate a swap position at an advantageous time or price, which may result in significant losses.

Roundhill MSTR WeeklyPay™ ETF | REGULATED INVESTMENT COMPANY TAX RISKS

Risk [Text Block]

REGULATED INVESTMENT COMPANY TAX RISKS. The Fund intends to qualify annually and to elect to be treated as a regulated investment company under the Internal Revenue Code of 1986, as amended (the “Code”). To qualify for the favorable U.S. federal income tax treatment generally accorded to regulated investment companies, the Fund must, among other things, (i) derive in each taxable year at least 90% of its gross income from dividends, interest, payments with respect to securities loans and gains from the sale or other disposition of stock, securities or foreign currencies or other income derived with respect to its business of investing in such stock, securities or currencies, or net income derived from interests in certain publicly traded partnerships; (ii) diversify its holdings so that, at the end of each quarter of the taxable year, (a) at least 50% of the market value of the Fund’s assets is represented by cash and cash items (including receivables), U.S. government securities, the securities of other regulated investment companies and other securities, with such other securities of any one issuer generally limited for the purposes of this calculation to an amount not greater than 5% of the value of the Fund’s total assets and not greater than 10% of the outstanding voting securities of such issuer, and (b) not more than 25% of the value of its total assets is invested in the securities (other than U.S. government securities or the securities of other regulated investment companies) of any one issuer, or two or more issuers which the Fund controls which are engaged in the same, similar or related trades or businesses, or the securities of one or more of certain publicly traded partnerships; and (iii) distribute at least 90% of its investment company taxable income (which includes, among other items, dividends, interest and net short-term capital gains in excess of net long-term capital losses) and at least 90% of its net tax-exempt interest income each taxable year. There are certain exceptions for failure to qualify if the failure is for reasonable cause or is de minimis, and certain corrective action is taken and certain tax payments are made by the Fund.

 

If the Fund were to fail to meet the qualifying income test or asset diversification test and fail to qualify as a RIC, it would be taxed in the same manner as an ordinary corporation, and distributions to its shareholders would not be deductible by the Fund in computing its taxable income, which would adversely affect the Fund’s performance.

Prospectus [Line Items]  
Risk [Text Block]

UNITED STATES GOVERNMENT SECURITIES RISK. The Fund may invest directly in short-term U.S. government securities or in ETFs that hold short-term U.S. government securities. U.S. government securities are subject to interest rate risk but generally do not involve the credit risks associated with investments in other types of debt securities. As a result, the yields available from U.S. government securities are generally lower than the yields available from other debt securities. U.S. government securities are guaranteed only as to the timely payment of interest and the payment of principal when held to maturity.

Roundhill MSTR WeeklyPay™ ETF | LARGE SHAREHOLDER RISK  
Prospectus [Line Items]  
Risk [Text Block]

LARGE SHAREHOLDER RISK. Certain shareholders, including affiliated funds advised by the Adviser, may from time to time own a significant portion of the Fund’s shares. In addition, a third-party investor, the Adviser or an affiliate of the Adviser (“Affiliate”), an authorized participant, a market maker, or another entity may invest in the Fund and hold its investment for a limited period solely to facilitate the commencement of the Fund or to help the Fund achieve a specified size or scale. There can be no assurance that any large shareholder will not redeem its investment, that the size of the Fund will be maintained at such levels, or that the Fund will continue to meet applicable listing requirements. Redemptions by large shareholders could have a significant negative impact on the Fund. In addition, transactions by large shareholders may account for a large percentage of the trading volume on the Fund’s listing exchange and may, therefore, have a material upward or downward effect on the market price of the shares.

 

To the extent that a significant percentage of the Fund’s shares are owned or controlled by a small number of account shareholders (or a single account shareholder), including funds or accounts over which the Adviser or an Affiliate has investment discretion, the Fund is subject to the risk that those shareholders may purchase or redeem Fund shares in significant amounts rapidly or unexpectedly, including as a result of an asset allocation decision made by the Adviser or an Affiliate. This may adversely affect the Fund’s performance if the Adviser is forced to sell portfolio securities or invest cash when it would not otherwise choose to do so. Redemptions of a large number of shares may affect the liquidity of the Fund’s portfolio, increase the Fund’s transaction costs, and accelerate the realization of taxable income and/or gains. In addition, a large redemption could result in the Fund’s current expenses being allocated over a smaller asset base, leading to an increase in the Fund’s gross expense ratio. Large purchases of the Fund’s shares may also adversely affect the Fund’s performance to the extent that the Fund is delayed in investing new cash or otherwise maintains a larger cash position than it ordinarily would, particularly if the Fund accepts cash for an order for the purchase of creation units of the Fund’s shares.

Roundhill MSTR WeeklyPay™ ETF | MSTR INVESTING RISKS  
Prospectus [Line Items]  
Risk [Text Block]

MSTR INVESTING RISKS. The Fund will have significant exposure to MSTR through its investments in swap agreements and FLEX Options that utilize MSTR as the reference asset. Accordingly, the Fund will subject to the risks of MSTR, set forth below.

 

MSTR ISSUER-SPECIFIC RISKS. Issuer-specific attributes may cause an investment held by the Fund to be more volatile than the market generally. The value of an individual security or particular type of security may be more volatile than the market as a whole and may perform differently from the value of the market as a whole. MSTR holds billions of dollars in bitcoin as part of its corporate treasury strategy. Its stock price is highly correlated with bitcoin’s price movements, making it more volatile than traditional technology stocks. Governments worldwide are increasing regulatory oversight on digital assets, including bitcoin. Any new taxation policies, restrictions on corporate bitcoin holdings, or changes in accounting rules could impact MSTR’s financial position. To acquire more bitcoin, MSTR has issued debt and convertible notes. If bitcoin’s price declines significantly, the company could face margin calls, liquidity shortages or difficulties in refinancing debt obligations. MSTR competes with major business intelligence and data analytics firms. These competitors may offer more advanced features, better integration, or superior cloud-based solutions. While MSTR generates revenue from its software offerings, the company’s bitcoin focus may affect its ability to retain enterprise customers who prefer providers with a long-term focus on product development. Bitcoin is often viewed as a speculative asset, and macroeconomic factors such as recession fears, liquidity constraints, or monetary tightening could drive significant fluctuations in MSTR’s stock price.

 

INDIRECT INVESTMENT RISK. MSTR is not affiliated with the Trust, the Fund, the Adviser, the Sub-Adviser or any affiliates thereof and is not involved with this offering in any way and has no obligation to consider the Fund in taking any corporate actions that might affect the value of the Fund. The Trust, the Fund, the Adviser, the Sub-Adviser or any affiliate are not responsible for the performance of MSTR and make no representation as to the performance of MSTR. Investing in the Fund is not equivalent to investing in MSTR. Fund shareholders will not have voting rights or rights to receive dividends or other distributions or any other rights with respect to MSTR.

 

BITCOIN RISK. MSTR’s value is significantly influenced by the large amount of bitcoin it holds. Bitcoin remains a volatile and evolving asset subject to significant market fluctuations, uncertainty, and speculative investment interest. Although increased institutional adoption and regulatory clarity have recently improved market stability and broader acceptance, the value of bitcoin continues to be influenced substantially by market sentiment, speculative demand, and macroeconomic factors rather than traditional fundamental analysis alone. The further development and sustained acceptance of the Bitcoin network are dependent on a variety of complex factors, including technological advancements, regulatory developments, institutional participation, and broader public adoption. While regulatory oversight of bitcoin and related digital assets has notably increased, particularly in jurisdictions like the United States and Europe, the global regulatory landscape remains fragmented. Sudden or significant regulatory actions—including new legislation, enforcement actions against key market participants, or policy shifts—can still materially impact bitcoin’s valuation and liquidity. Bitcoin markets remain susceptible to manipulation, fraud, theft, cybersecurity incidents, and operational disruptions, especially on trading platforms that lack robust regulatory oversight or proper cybersecurity standards. Furthermore, a significant concentration of bitcoin holdings among a limited number of large holders, often referred to as “whales,” continues to pose risks of price volatility or manipulation through coordinated transactions. Technological risks remain inherent in bitcoin and its underlying blockchain network. While advancements such as Layer 2 scaling solutions (e.g., the Lightning Network) have made meaningful progress toward addressing scalability and usability concerns, these technologies are still evolving and carry risks of technical vulnerabilities, hacking, and operational failures that may undermine confidence or negatively affect bitcoin’s value. The potential for blockchain forks—where disagreements among developers and stakeholders lead to competing blockchains—continues to exist. Although fewer contentious forks have occurred in recent times, such events could reoccur, introducing market confusion, diluting value, or weakening confidence in the Bitcoin blockchain. Competition from alternative blockchain networks and digital assets remains strong. Networks like Ethereum and other blockchain platforms with smart contract capabilities, privacy features, or superior scalability may attract broader adoption, thereby reducing bitcoin’s relative attractiveness or limiting its potential as an alternative payment system or digital store of value. Any of these risks, individually or collectively, could materially and adversely affect the acceptance and market value of bitcoin, consequently impacting the value of shares of MSTR.

 

BLOCKCHAIN TECHNOLOGY RISK. Blockchain technology is a relatively new and untested technology that operates as a distributed ledger. There are risks associated with a company’s issuance, redemption, transfer, and recordkeeping of shares on a blockchain, and these risks may not fully emerge until the technology becomes more widely used. Blockchain systems are public and permissionless, and could be vulnerable to fraud, particularly if a significant minority of participants collude to defraud the rest. Access to a given blockchain requires a private key, which, if compromised, could result in loss due to theft, destruction, or inaccessibility. There is limited regulation of blockchain technology other than the intrinsic public nature of the blockchain system, and any future regulatory developments could adversely affect the viability and expansion of the use of blockchain technology. There are currently a number of competing blockchain platforms with competing intellectual property claims, and the uncertainty inherent in these competing technologies could cause companies to use alternatives to blockchain. Blockchain networks may also undergo significant technological developments, such as the Ethereum blockchain’s change in September 2022 from proof-of-work mining to proof-of-stake validation. Blockchain networks can also experience delays in transaction processing and settlement, particularly during periods of high network congestion or increased transaction volume. Such delays could affect the timing of recording and processing transactions. During periods of congestion, the time required for transaction validation may increase, which could lead to delayed recording of transactions on the blockchain or off-chain recordkeeping systems. Furthermore, blockchain networks typically impose transaction fees in the form of the network’s native digital asset. These fees can be unpredictable and may vary significantly depending on network conditions and levels of congestion. Lastly, there may be undiscovered technical flaws in blockchain-integrated recordkeeping system or the underlying blockchain technology, including in the process by which transactions are recorded to a blockchain, recorded off-chain, and/or integrated with other recordkeeping systems. Such flaws could negatively impact the execution or recordkeeping of transactions. Additionally, technological advancements may lead to new or existing hardware or software tools or mechanisms that could undermine the integrity or functionality of blockchain systems. Blockchain software is generally open-source. Any user can download the software, modify it and then propose that network adopt the modification. When a modification is introduced and a substantial majority of users consent to the modification, the change is implemented and the blockchain network remains uninterrupted. However, if less than a substantial majority of users consent to the proposed modification, and the blockchain consensus mechanism allows for the modification to nonetheless be implemented by some users and the modification is not compatible with the software prior to its modification, the consequence would be what is known as a “fork” (i.e., “split”) of the blockchain network (and the blockchain), with one version running the pre-modified software and the other running the modified software. The effect of such a fork would be the existence of two (or more) versions of the blockchain network running in parallel, but with each version’s native asset lacking interchangeability. Additionally, a fork could be introduced by an unintentional, unanticipated software flaw in the multiple versions of otherwise compatible software users run. If a fork occurs, the original blockchain and the forked blockchain could potentially compete with each other for users and other participants, leading to a loss of these for the original blockchain.

 

CUSTODY RISK. MSTR has substantial holdings of bitcoin. Accordingly, it is subject to the custody risk of its bitcoin holdings. Security breaches, computer malware and computer hacking attacks have been a prevalent concern in relation to digital assets. The bitcoin held by MSTR will likely be an appealing target to hackers or malware distributors seeking to destroy, damage or steal the MSTR’s bitcoins. To the extent that MSTR is unable to identify and mitigate or stop new security threats or otherwise adapt to technological changes in the digital asset industry, MSTR’s bitcoins may be subject to theft, loss, destruction or other attack.

 

MSTR has put security procedures in place to prevent such theft, loss or destruction, including but not limited to, offline storage, or cold storage, multiple encrypted private key “shards”, and other measures. Nevertheless, the security procedures cannot guarantee the prevention of any loss due to a security breach, software defect or act of God that may be borne by MSTR and the security procedures may not protect against all errors, software flaws or other vulnerabilities in MSTR’s technical infrastructure, which could result in theft, loss or damage of its assets. Assets not held in cold storage, such as assets held in a trading account, may be more vulnerable to security breach, hacking or loss than assets held in cold storage. Furthermore, assets held in a trading account are held on an omnibus, rather than segregated basis, which creates greater risk of loss.

 

The security procedures and operational infrastructure may be breached due to the actions of outside parties, error or malfeasance of a MSTR employee, and, as a result, an unauthorized party may obtain access to MSTR’s accounts where its bitcoin is held, the relevant private keys (and therefore bitcoin) or other data or property of MSTR. Additionally, outside parties may attempt to fraudulently induce employees of MSTR to disclose sensitive information in order to gain access to MSTR’s infrastructure. As the techniques used to obtain unauthorized access, disable or degrade service, or sabotage systems change frequently, or may be designed to remain dormant until a predetermined event and often are not recognized until launched against a target, MSTR may be unable to anticipate these techniques or implement adequate preventative measures.

 

DIGITAL ASSET TRADING PLATFORMS RISK. Digital asset trading platforms remain relatively new and vary significantly in terms of regulation, transparency, operational stability, and compliance standards. While certain prominent trading platforms—particularly those based in the United States—have substantially improved transparency, compliance, and regulatory adherence, many platforms still operate internationally or offshore with significantly less stringent oversight. Platforms located outside the United States may be subject to minimal or inconsistent regulatory enforcement and often do not provide sufficient public information regarding their management structure, ownership, financial stability, cybersecurity practices, or compliance controls. Despite increased institutional involvement, enhanced security measures, and more standardized operating practices adopted by leading platforms, digital asset exchanges continue to be vulnerable to cybersecurity threats, hacking incidents, fraudulent activities, operational disruptions, and other technical risks. High-profile failures, breaches, or shutdowns of major trading platforms or custodians—such as those arising from fraud, cybersecurity incidents, regulatory enforcement actions, or insolvency—can significantly reduce investor confidence, increase market volatility, and potentially trigger contagion effects across the digital asset ecosystem. Regulatory developments and enforcement actions continue to shape the landscape in which digital asset platforms operate. Recent regulatory scrutiny has heightened globally, particularly in jurisdictions with substantial trading volumes, such as the United States, Europe, and Asia. Increased regulatory oversight, while potentially positive for market stability in the long run, can create short-term disruption, reduce liquidity, prompt platform closures, or alter business models substantially, thereby affecting the prices of digital assets, including bitcoin. Investors should be aware that trading or custodying bitcoin on less transparent or poorly regulated platforms increases the risk of losing access to digital assets due to platform insolvency, hacking incidents, regulatory intervention, or operational failure. Although improvements have been made, the digital asset marketplace remains inherently riskier than traditional financial markets, and investors may have limited recourse if a digital asset trading platform fails or is compromised.

 

IRREVOCABILITY OF TRANSACTIONS RISK. Bitcoin transactions are typically not reversible without the consent and active participation of the recipient of the transaction. Once a transaction has been verified and recorded in a block that is added to the Bitcoin blockchain, an incorrect transfer or theft of bitcoin generally will not be reversible and MSTR may not be capable of seeking compensation for any such transfer or theft. It is possible that, through computer or human error, or through theft or criminal action, MSTR’s bitcoin could be transferred from its account in incorrect amounts or to unauthorized third parties, or to uncontrolled accounts.

 

INFORMATION TECHNOLOGY COMPANIES RISK. Information technology companies face intense competition, both domestically and internationally, which may have an adverse effect on profit margins. Like other technology companies, information technology companies may have limited product lines, markets, financial resources or personnel. The products of information technology companies may face obsolescence due to rapid technological developments, frequent new product introduction, unpredictable changes in growth rates and competition for the services of qualified personnel. Companies in the information technology sector are heavily dependent on patent and intellectual property rights. The loss or impairment of these rights may adversely affect the profitability of these companies. Information technology companies are facing increased government and regulatory scrutiny and may be subject to adverse government or regulatory action.

 

LARGE CAPITALIZATION COMPANIES RISK. Large capitalization companies may be less able than smaller capitalization companies to adapt to changing market conditions. Large capitalization companies may be more mature and subject to more limited growth potential compared with smaller capitalization companies. During different market cycles, the performance of large capitalization companies has trailed the overall performance of the broader securities markets.

 

UNITED STATES RISK. Certain changes in the U.S. economy, such as when the U.S. economy weakens or when its financial markets decline, may have an adverse effect on the securities to which the Fund has exposure.

NON-DIVERSIFICATION RISK. As a “non-diversified” fund, the Fund may hold a smaller number of portfolio securities than many other funds. To the extent the Fund invests in a relatively small number of issuers, a decline in the market value of a particular security held by the Fund may affect its value more than if it invested in a larger number of issuers. The value of Fund Shares may be more volatile than the values of shares of more diversified funds.

MARKET RISK. Market risk is the risk that a particular investment, or Fund Shares in general, may fall in value. Securities are subject to market fluctuations caused by real or perceived adverse economic, political, and regulatory factors or market developments, changes in interest rates, disruptions to trade, impositions of tariffs and perceived trends in securities prices. Fund Shares could decline in value or underperform other investments. In addition, local, regional or global events such as war, acts of terrorism, market manipulation, government defaults, government shutdowns, regulatory actions, political changes, diplomatic developments, the imposition of sanctions and other similar measures, spread of infectious diseases or other public health issues, recessions, natural disasters, or other events could have a significant negative impact on the Fund and its investments. Any of such circumstances could have a materially negative impact on the value of Fund Shares, the liquidity of an investment, and may result in increased market volatility. During any such events, Fund Shares may trade at increased premiums or discounts to their net asset value, the bid/ask spread on Fund Shares may widen and the returns on investment may fluctuate.

ACTIVE MANAGEMENT RISK. The Fund is actively-managed and its performance reflects investment decisions that the Adviser and/or Sub-Adviser makes for the Fund. Such judgments about the Fund’s investments may prove to be incorrect. If the investments selected and the strategies employed by the Fund fail to produce the intended results, the Fund could underperform as compared to other funds with similar investment objectives and/or strategies, or could have negative returns. The Adviser/Sub-Adviser will seek to employ the Fund’s investment strategy regardless of whether there are periods of adverse market, economic, or other conditions and will not seek to take temporary defensive positions during such periods.

CONCENTRATION RISK. The Fund may be susceptible to an increased risk of loss, including losses due to adverse events that affect the Fund’s investments more than the market as a whole, to the extent that the Fund’s investments are concentrated in the securities and/or other assets of a particular issuer or issuers, country, group of countries, region, market, industry, group of industries, sector, market segment or asset class.

Roundhill S&P 500® No Dividend Target ETF | CURRENT MARKET CONDITIONS RISK  
Prospectus [Line Items]  
Risk [Text Block]

CURRENT MARKET CONDITIONS RISK. Current market conditions risk is the risk that a particular investment, or Fund Shares in general, may fall in value due to current market conditions. As a means to fight inflation, which remains at elevated levels, the Federal Reserve and certain foreign central banks have raised interest rates; however, the Federal Reserve has recently lowered interest rates and may continue to do so. U.S. regulators have proposed several changes to market and issuer regulations which would directly impact the Fund, and any regulatory changes could adversely impact the Fund’s ability to achieve its investment strategies or make certain investments. Recent and potential future bank failures could result in disruption to the broader banking industry or markets generally and reduce confidence in financial institutions and the economy as a whole, which may also heighten market volatility and reduce liquidity. Additionally, challenges in commercial real estate markets, including rising interest rates, declining valuations and increasing vacancies, could have a broader impact on financial markets. The ongoing adversarial political climate in the United States, as well as political and diplomatic events both domestic and abroad, have and may continue to have an adverse impact the U.S. regulatory landscape, markets and investor behavior, which could have a negative impact on the Fund’s investments and operations. The change in administration resulting from the 2024 United States national elections could result in significant impacts to international trade relations, tax and immigration policies, and other aspects of the national and international political and financial landscape, which could affect, among other things, inflation and the securities markets generally. Other unexpected political, regulatory and diplomatic events within the U.S. and abroad may affect investor and consumer confidence and may adversely impact financial markets and the broader economy. For example, ongoing armed conflicts between Russia and Ukraine in Europe and among Israel, Iran, Hamas and other militant groups in the Middle East, have caused and could continue to cause significant market disruptions and volatility within the markets in Russia, Europe, the Middle East and the United States. The hostilities and sanctions resulting from those hostilities have and could continue to have a significant impact on certain Fund investments as well as Fund performance and liquidity. The economies of the United States and its trading partners, as well as the financial markets generally, may be adversely impacted by trade disputes, including the imposition of tariffs, and other matters. For example, the United States has imposed trade barriers and restrictions on China. In addition, the Chinese government is engaged in a longstanding dispute with Taiwan, continually threatening an invasion. If the political climate between the United States and China does not improve or continues to deteriorate, if China were to attempt invading Taiwan, or if other geopolitical conflicts develop or worsen, economies, markets and individual securities may be adversely affected, and the value of the Fund’s assets may go down. A public health crisis and the ensuing policies enacted by governments and central banks may cause significant volatility and uncertainty in global financial markets, negatively impacting global growth prospects. As the COVID-19 global pandemic illustrated, such events may affect certain geographic regions, countries, sectors and industries more significantly than others. Advancements in technology may also adversely impact markets and the overall performance of the Fund. For instance, the economy may be significantly impacted by the advanced development and increased regulation of artificial intelligence. Additionally, cyber security breaches of both government and non-government entities could have negative impacts on infrastructure and the ability of such entities, including the Fund, to operate properly. These events, and any other future events, may adversely affect the prices and liquidity of the Fund’s portfolio investments and could result in disruptions in the trading markets.

Roundhill S&P 500® No Dividend Target ETF | CYBERSECURITY RISK  
Prospectus [Line Items]  
Risk [Text Block]

CYBERSECURITY RISK. Failures or breaches of the electronic systems of the Fund, the Fund’s adviser, sub-adviser, distributor and other service providers, market makers, Authorized Participants or the issuers of securities in which the Fund invests have the ability to cause disruptions, negatively impact the Fund’s business operations and/or potentially result in financial losses to the Fund and its shareholders. While the Fund has established business continuity plans and risk management systems seeking to address system breaches or failures, there are inherent limitations in such plans and systems. Furthermore, the Fund cannot control the cybersecurity plans and systems of the Fund’s other service providers, market makers, Authorized Participants or issuers of securities in which the Fund invests.

Roundhill S&P 500® No Dividend Target ETF | OPERATIONAL RISK  
Prospectus [Line Items]  
Risk [Text Block]

OPERATIONAL RISK. The Fund is subject to risks arising from various operational factors, including, but not limited to, human error, processing and communication errors, errors of the Fund’s service providers, counterparties or other third-parties, failed or inadequate processes and technology or systems failures. The Fund relies on third-parties for a range of services, including custody. Any delay or failure relating to engaging or maintaining such service providers may affect the Fund’s ability to meet its investment objective. Although the Fund and the Adviser seek to reduce these operational risks through controls and procedures, there is no way to completely protect against such risks.

Roundhill S&P 500® No Dividend Target ETF | STRUCTURAL ETF RISKS  
Prospectus [Line Items]  
Risk [Text Block]

STRUCTURAL ETF RISKS. The Fund is an ETF. Accordingly, it is subject to certain risks associated with its unique structure.

 

Active Market Risk. Although Fund Shares are listed for trading on the Exchange, there can be no assurance that an active trading market for Fund Shares will develop or be maintained. Fund Shares trade on the Exchange at market prices that may be below, at or above the Fund’s net asset value. Securities, including Fund Shares, are subject to market fluctuations and liquidity constraints that may be caused by such factors as economic, political, or regulatory developments, changes in interest rates, and/or perceived trends in securities prices. Fund Shares could decline in value or underperform other investments.

 

Market Participants Risk. Only an Authorized Participant may engage in creation or redemption transactions directly with the Fund, and none of those Authorized Participants is obligated to engage in creation and/or redemption transactions. The Fund has a limited number of institutions that may act as Authorized Participants on an agency basis (i.e., on behalf of other market participants). To the extent that Authorized Participants exit the business or are unable to proceed with creation or redemption orders with respect to the Fund and no other Authorized Participant is able to step forward to create or redeem, Fund Shares may be more likely to trade at a premium or discount to net asset value (“NAV”) and possibly face trading halts or delisting. The Fund may also rely on a small number of third-party market makers to provide a market for the purchase and sale of Fund Shares but such market makers are under no obligation to do so. Decisions by Authorized Participants or market makers to reduce their role or step away from these activities in times of market stress could inhibit the effectiveness of the arbitrage process in maintaining the relationship between the underlying values of the Fund’s portfolio securities and the Fund’s market price. Any trading halt or other problem relating to the trading activity of these market makers or any issues disrupting the Authorized Participants’ ability to proceed with creation and/or redemption orders could result in a dramatic change in the spread between the Fund’s net asset value and the price at which Fund Shares are trading on the Exchange, which could result in a decrease in value of Fund Shares. This reduced effectiveness could result in Fund Shares trading at a premium or discount to net asset value and also in greater than normal intraday bid-ask spreads Fund Shares.

 

Cash Transactions Risk. The Fund may effect a portion of its creations and redemptions for cash, rather than in-kind securities. Paying redemption proceeds in cash rather than through in-kind delivery of portfolio securities may require the Fund to dispose of or sell portfolio securities or other assets at an inopportune time to obtain the cash needed to meet redemption orders. This may cause the Fund to sell a security and recognize a capital gain or loss that might not have been incurred if it had made a redemption in-kind. As a result, the Fund may pay out higher or lower annual capital gains distributions than ETFs that redeem in-kind. The use of cash creations and redemptions may also cause the Fund Shares to trade in the market at greater bid-ask spreads or greater premiums or discounts to the Fund’s NAV. Furthermore, the Fund may not be able to execute cash transactions for creation and redemption purposes at the same price used to determine the Fund’s NAV. To the extent that the maximum additional charge for creation or redemption transactions is insufficient to cover the execution shortfall, the Fund’s performance could be negatively impacted.

 

Costs of Buying and Selling Fund Shares. Due to the costs of buying or selling Fund Shares, including brokerage commissions imposed by brokers and bid/ask spreads, frequent trading of Fund Shares may significantly reduce investment results and an investment in Fund Shares may not be advisable for investors who anticipate regularly making small investments.

 

Premium/Discount Risk. As with all ETFs, Fund Shares may be bought and sold in the secondary market at market prices. The trading prices of Fund Shares in the secondary market may differ from the Fund’s daily NAV per share and there may be times when the market price of the shares is more than the NAV per share (premium) or less than the NAV per share (discount). If a shareholder purchases Fund Shares at a time when the market price is at a premium to the NAV or sells Fund Shares at a time when the market price is at a discount to the NAV, the shareholder may pay more for, or receive less than, the underlying value of the Fund Shares, respectively. This risk is heightened in times of market volatility or periods of steep market declines.

 

Trading Risks. Although Fund Shares are listed for trading on the Exchange and may be traded on U.S. exchanges other than the Exchange, there can be no assurance that Fund Shares will trade with any volume, or at all, on any stock exchange. In stressed market conditions, the liquidity of Fund Shares may begin to mirror the liquidity of the Fund’s underlying portfolio holdings, which can be significantly less liquid than Fund Shares. Trading in Fund Shares on the Exchange may be halted due to market conditions or for reasons that, in the view of the Exchange, make trading in Fund Shares inadvisable. In addition, trading in Fund Shares on the Exchange is subject to trading halts caused by extraordinary market volatility pursuant to the Exchange’s “circuit breaker” rules. There can be no assurance that the requirements of the Exchange necessary to maintain the listing of the Fund will continue to be met or will remain unchanged.

Roundhill S&P 500® No Dividend Target ETF | NEW FUND RISK

NEW FUND RISK. The Fund is a recently organized investment company with a limited operating history. As a result, prospective investors have a limited track record or history on which to base their investment decision.

Roundhill S&P 500® No Dividend Target ETF | INVESTMENT STRATEGY RISK  
Prospectus [Line Items]  
Risk [Text Block]

INVESTMENT STRATEGY RISK. There is no guarantee that the Fund will be able to successfully avoid paying dividends and distributions. Additionally, there can be no guarantee that the Fund will be successful in its strategy to provide shareholders with a total return that matches that of the S&P 500® Index. In order to effectuate the Fund’s strategy, the Adviser is relying upon the ability to conduct in-kind redemptions of the Fund’s S&P 500 ETF holdings. In the event that the Adviser is unable to do so due to factors such as broker-dealer balance sheet availability constraints, market volatility, regulatory changes, contrary IRS positions relating to an ETF’s use of in-kind creations or redemptions, or operational issues, the ability of the Adviser to avoid the taxable income generated by an investment in Fund Shares may be impaired and may force the Fund to make a dividend or distribution payment.

Roundhill S&P 500® No Dividend Target ETF | ASSET CONCENTRATION RISK  
Prospectus [Line Items]  
Risk [Text Block]

ASSET CONCENTRATION RISK. Since the Fund’s portfolio will be composed of a very small number of ETFs (including a single ETF), the Fund’s performance may be hurt disproportionately and significantly by the poor performance of those ETFs to which it has significant exposure. Asset concentration makes the Fund more susceptible to any single occurrence affecting the ETFs and may subject the Fund to greater market risk than more diversified funds.

S&P 500 ETFS RISKS. The Fund will have significant exposure to the S&P 500® Index through its investments in the S&P 500 ETFs. Accordingly, the Fund will subject to the risks of the S&P 500 ETFs, set forth below. In addition to these risks, each S&P 500 ETF is also subject to the following risks to which the Fund is also subject, which are described within the section entitled “Principal Risks”: Active Market Risk, Asset Class Risk, Concentration Risk, Cybersecurity Risk, Operational Risk and Structural ETF Risk.

 

EQUITY SECURITIES RISK. Equity securities are subject to changes in value, and their values may be more volatile than those of other asset classes. Equity securities prices fluctuate for several reasons, including changes in investors’ perceptions of the financial condition of an issuer or the general condition of the relevant equity market, such as market volatility, or when political or economic events affecting an issuer occur. Common stock prices may be particularly sensitive to rising interest rates, as the cost of capital rises and borrowing costs increase. Common stocks generally subject their holders to more risks than preferred stocks and debt securities because common stockholders’ claims are subordinated to those of holders of preferred stocks and debt securities upon the bankruptcy of the issuer.

 

INFORMATION TECHNOLOGY COMPANIES RISK. Information technology companies face intense competition, both domestically and internationally, which may have an adverse effect on profit margins. Like other technology companies, information technology companies may have limited product lines, markets, financial resources or personnel. The products of information technology companies may face obsolescence due to rapid technological developments, frequent new product introduction, unpredictable changes in growth rates and competition for the services of qualified personnel. Companies in the information technology sector are heavily dependent on patent and intellectual property rights. The loss or impairment of these rights may adversely affect the profitability of these companies. Information technology companies are facing increased government and regulatory scrutiny and may be subject to adverse government or regulatory action.

 

ISSUER RISK. The performance of an ETF depends on the performance of individual securities to which the ETF has exposure. Changes in the financial condition or credit rating of an issuer of those securities may cause the value of the securities to decline. There is no guarantee that an issuer that paid dividends in the past will continue to do so in the future or will continue paying dividends at the same level.

 

LARGE CAPITALIZATION COMPANIES RISK. Large capitalization companies may be less able than smaller capitalization companies to adapt to changing market conditions. Large capitalization companies may be more mature and subject to more limited growth potential compared with smaller capitalization companies. During different market cycles, the performance of large capitalization companies has trailed the overall performance of the broader securities markets.

 

PASSIVE INVESTMENT RISK. The S&P 500 ETFs are not actively managed and therefore would not sell an equity security due to current or projected underperformance of a security, industry or sector, unless that security is removed from the S&P 500® Index. Unlike with an actively managed fund, the fund’s investment adviser does not use techniques or defensive strategies designed to lessen the effects of market volatility or to reduce the impact of periods of market decline. This means that, based on market and economic conditions, the fund’s performance could be lower than other types of funds that may actively shift their portfolio assets to take advantage of market opportunities or to lessen the impact of a market decline.

 

TRACKING ERROR RISK. The S&P 500 ETFs are subject to “tracking error,” which is the divergence of an ETF’s performance from that of the index which it seeks to track. Tracking error may occur because of differences between the securities and other instruments held in an ETF’s portfolio and those included in the index, pricing differences, transaction costs incurred by the ETF, the ETF’s holding of uninvested cash, differences in timing of the accrual of or the valuation of dividends or interest received by the ETF or distributions paid to the ETF’s shareholders, the requirements to maintain pass-through tax treatment, portfolio transactions carried out to minimize the distribution of capital gains to shareholders, acceptance of custom baskets, changes to the index or the costs to the ETF of complying with various new or existing regulatory requirements, among other reasons. This risk may be heightened during times of increased market volatility or other unusual market conditions. Tracking error also may result because the ETF incurs fees and expenses, while the index it tracks does not.

 

UNITED STATES RISK. Certain changes in the U.S. economy, such as when the U.S. economy weakens or when its financial markets decline, may have an adverse effect on the securities to which the Fund has exposure.

Risk [Text Block]

NON-DIVERSIFICATION RISK. As a “non-diversified” fund, the Fund may hold a smaller number of portfolio securities than many other funds. To the extent the Fund invests in a relatively small number of issuers, a decline in the market value of a particular security held by the Fund may affect its value more than if it invested in a larger number of issuers. The value of the Fund Shares may be more volatile than the values of shares of more diversified funds.

Roundhill Humanoid Robotics ETF | MARKET RISK  
Prospectus [Line Items]  
Risk [Text Block]

MARKET RISK. Market risk is the risk that a particular investment, or Fund Shares in general, may fall in value. Securities are subject to market fluctuations caused by real or perceived adverse economic, political, and regulatory factors or market developments, changes in interest rates, disruptions to trade, impositions of tariffs and perceived trends in securities prices. Fund Shares could decline in value or underperform other investments. In addition, local, regional or global events such as war, acts of terrorism, market manipulation, government defaults, government shutdowns, regulatory actions, political changes, diplomatic developments, the imposition of sanctions and other similar measures, spread of infectious diseases or other public health issues, recessions, natural disasters, or other events could have a significant negative impact on the Fund and its investments. Any of such circumstances could have a materially negative impact on the value of Fund Shares, the liquidity of an investment, and may result in increased market volatility. During any such events, Fund Shares may trade at increased premiums or discounts to their net asset value, the bid/ask spread on Fund Shares may widen and the returns on investment may fluctuate.

Roundhill Humanoid Robotics ETF | ACTIVE MANAGEMENT RISK  
Prospectus [Line Items]  
Risk [Text Block]

ACTIVE MANAGEMENT RISK. The Fund is actively-managed and its performance reflects investment decisions that the Adviser and/or Sub-Adviser makes for the Fund. Such judgments about the Fund’s investments may prove to be incorrect. If the investments selected and the strategies employed by the Fund fail to produce the intended results, the Fund could underperform as compared to other funds with similar investment objectives and/or strategies, or could have negative returns.

Roundhill Humanoid Robotics ETF | ASSET CLASS RISK

ASSET CLASS RISK. Securities and other assets in the Fund’s portfolio may underperform in comparison to the general financial markets, a particular financial market or other asset classes.

Roundhill Humanoid Robotics ETF | CONCENTRATION RISK  
Prospectus [Line Items]  
Risk [Text Block]

CONCENTRATION RISK. The Fund is concentrated in the industry or group of industries comprising the industrials, information technology and consumer discretionary sectors, collectively. The Fund may be susceptible to an increased risk of loss, including losses due to adverse events that affect the Fund’s investments more than the market as a whole, to the extent that the Fund’s investments are concentrated in the securities and/or other assets of a particular issuer or issuers, country, group of countries, region, market, industry, group of industries, sector, market segment or asset class.

Roundhill Humanoid Robotics ETF | CURRENT MARKET CONDITIONS RISK  
Prospectus [Line Items]  
Risk [Text Block]

CURRENT MARKET CONDITIONS RISK. Current market conditions risk is the risk that a particular investment, or Fund Shares in general, may fall in value due to current market conditions. As a means to fight inflation, which remains at elevated levels, the Federal Reserve and certain foreign central banks have raised interest rates; however, the Federal Reserve has recently lowered interest rates and may continue to do so. U.S. regulators have proposed several changes to market and issuer regulations which would directly impact the Fund, and any regulatory changes could adversely impact the Fund’s ability to achieve its investment strategies or make certain investments. Recent and potential future bank failures could result in disruption to the broader banking industry or markets generally and reduce confidence in financial institutions and the economy as a whole, which may also heighten market volatility and reduce liquidity. Additionally, challenges in commercial real estate markets, including rising interest rates, declining valuations and increasing vacancies, could have a broader impact on financial markets. The ongoing adversarial political climate in the United States, as well as political and diplomatic events both domestic and abroad, have and may continue to have an adverse impact the U.S. regulatory landscape, markets and investor behavior, which could have a negative impact on the Fund’s investments and operations. The change in administration resulting from the 2024 United States national elections could result in significant impacts to international trade relations, tax and immigration policies, and other aspects of the national and international political and financial landscape, which could affect, among other things, inflation and the securities markets generally. Other unexpected political, regulatory and diplomatic events within the U.S. and abroad may affect investor and consumer confidence and may adversely impact financial markets and the broader economy. For example, ongoing armed conflicts between Russia and Ukraine in Europe and among Israel, Iran, Hamas and other militant groups in the Middle East, have caused and could continue to cause significant market disruptions and volatility within the markets in Russia, Europe, the Middle East and the United States. The hostilities and sanctions resulting from those hostilities have and could continue to have a significant impact on certain Fund investments as well as Fund performance and liquidity. The economies of the United States and its trading partners, as well as the financial markets generally, may be adversely impacted by trade disputes, including the imposition of tariffs, and other matters. For example, the United States has imposed trade barriers and restrictions on China. In addition, the Chinese government is engaged in a longstanding dispute with Taiwan, continually threatening an invasion. If the political climate between the United States and China does not improve or continues to deteriorate, if China were to attempt invading Taiwan, or if other geopolitical conflicts develop or worsen, economies, markets and individual securities may be adversely affected, and the value of the Fund’s assets may go down. A public health crisis and the ensuing policies enacted by governments and central banks may cause significant volatility and uncertainty in global financial markets, negatively impacting global growth prospects. As the COVID-19 global pandemic illustrated, such events may affect certain geographic regions, countries, sectors and industries more significantly than others. Advancements in technology may also adversely impact markets and the overall performance of the Fund. For instance, the economy may be significantly impacted by the advanced development and increased regulation of artificial intelligence. Additionally, cyber security breaches of both government and non-government entities could have negative impacts on infrastructure and the ability of such entities, including the Fund, to operate properly. These events, and any other future events, may adversely affect the prices and liquidity of the Fund’s portfolio investments and could result in disruptions in the trading markets.

Roundhill Humanoid Robotics ETF | CYBERSECURITY RISK  
Prospectus [Line Items]  
Risk [Text Block]

CYBERSECURITY RISK. Failures or breaches of the electronic systems of the Fund, the Fund’s adviser, sub-adviser, distributor, and other service providers, market makers, Authorized Participants or the issuers of securities in which the Fund invests have the ability to cause disruptions, negatively impact the Fund’s business operations and/or potentially result in financial losses to the Fund and its shareholders. While the Fund has established business continuity plans and risk management systems seeking to address system breaches or failures, there are inherent limitations in such plans and systems. Furthermore, the Fund cannot control the cybersecurity plans and systems of the Fund’s other service providers, market makers, Authorized Participants or issuers of securities in which the Fund invests.

Roundhill Humanoid Robotics ETF | OPERATIONAL RISK  
Prospectus [Line Items]  
Risk [Text Block]

OPERATIONAL RISK. The Fund is subject to risks arising from various operational factors, including, but not limited to, human error, processing and communication errors, errors of the Fund’s service providers, counterparties or other third-parties, failed or inadequate processes and technology or systems failures. The Fund relies on third-parties for a range of services, including custody. Any delay or failure relating to engaging or maintaining such service providers may affect the Fund’s ability to meet its investment objective. Although the Fund and the Adviser seek to reduce these operational risks through controls and procedures, there is no way to completely protect against such risks.

Roundhill Humanoid Robotics ETF | STRUCTURAL ETF RISKS  
Prospectus [Line Items]  
Risk [Text Block]

STRUCTURAL ETF RISKS. The Fund is an ETF. Accordingly, it is subject to certain risks associated with its unique structure.

 

Cash Transactions Risk. The Fund may effect a portion of its creations and redemptions for cash, rather than in-kind securities. Paying redemption proceeds in cash rather than through in-kind delivery of portfolio securities may require the Fund to dispose of or sell portfolio securities or other assets at an inopportune time to obtain the cash needed to meet redemption orders. This may cause the Fund to sell a security and recognize a capital gain or loss that might not have been incurred if it had made a redemption in-kind. As a result, the Fund may pay out higher or lower annual capital gains distributions than ETFs that redeem in-kind. The use of cash creations and redemptions may also cause the Fund Shares to trade in the market at greater bid-ask spreads or greater premiums or discounts to the Fund’s NAV. Furthermore, the Fund may not be able to execute cash transactions for creation and redemption purposes at the same price used to determine the Fund’s NAV. To the extent that the maximum additional charge for creation or redemption transactions is insufficient to cover the execution shortfall, the Fund’s performance could be negatively impacted.

 

Active Market Risk. Although Fund Shares are listed for trading on the Exchange, there can be no assurance that an active trading market for Fund Shares will develop or be maintained. Fund Shares trade on the Exchange at market prices that may be below, at or above the Fund’s net asset value. Securities, including Fund Shares, are subject to market fluctuations and liquidity constraints that may be caused by such factors as economic, political, or regulatory developments, changes in interest rates, and/or perceived trends in securities prices. Fund Shares could decline in value or underperform other investments.

 

Market Participants Risk. Only an Authorized Participant may engage in creation or redemption transactions directly with the Fund, and none of those Authorized Participants is obligated to engage in creation and/or redemption transactions. The Fund has a limited number of institutions that may act as Authorized Participants on an agency basis (i.e., on behalf of other market participants). To the extent that Authorized Participants exit the business or are unable to proceed with creation or redemption orders with respect to the Fund and no other Authorized Participant is able to step forward to create or redeem, Fund Shares may be more likely to trade at a premium or discount to NAV and possibly face trading halts or delisting. The Fund may also rely on a small number of third-party market makers to provide a market for the purchase and sale of Fund Shares but such market makers are under no obligation to do so. Decisions by Authorized Participants or market makers to reduce their role or step away from these activities in times of market stress could inhibit the effectiveness of the arbitrage process in maintaining the relationship between the underlying values of the Fund’s portfolio securities and the Fund’s market price. Any trading halt or other problem relating to the trading activity of these market makers or any issues disrupting the Authorized Participants’ ability to proceed with creation and/or redemption orders could result in a dramatic change in the spread between the Fund’s net asset value and the price at which Fund Shares are trading on the Exchange, which could result in a decrease in value of Fund Shares. This reduced effectiveness could result in Fund Shares trading at a premium or discount to net asset value and also in greater than normal intraday bid-ask spreads Fund Shares.

 

Costs of Buying and Selling Fund Shares. Due to the costs of buying or selling Fund Shares, including brokerage commissions imposed by brokers and bid/ask spreads, frequent trading of Fund Shares may significantly reduce investment results and an investment in Fund Shares may not be advisable for investors who anticipate regularly making small investments.

 

Premium/Discount Risk. As with all ETFs, Fund Shares may be bought and sold in the secondary market at market prices. The trading prices of Fund Shares in the secondary market may differ from the Fund’s daily NAV per share and there may be times when the market price of the shares is more than the net asset value per share (premium) or less than the NAV per share (discount). If a shareholder purchases Fund Shares at a time when the market price is at a premium to the NAV or sells Fund Shares at a time when the market price is at a discount to the NAV, the shareholder may pay more for, or receive less than, the underlying value of the Fund Shares, respectively. This risk is heightened in times of market volatility or periods of steep market declines.

 

Trading Risks. Although Fund Shares are listed for trading on the Exchange and may be traded on U.S. exchanges other than the Exchange, there can be no assurance that Fund Shares will trade with any volume, or at all, on any stock exchange. In stressed market conditions, the liquidity of Fund Shares may begin to mirror the liquidity of the Fund’s underlying portfolio holdings, which can be significantly less liquid than Fund Shares. Trading in Fund Shares on the Exchange may be halted due to market conditions or for reasons that, in the view of the Exchange, make trading in Fund Shares inadvisable. In addition, trading in Fund Shares on the Exchange is subject to trading halts caused by extraordinary market volatility pursuant to the Exchange’s “circuit breaker” rules. There can be no assurance that the requirements of the Exchange necessary to maintain the listing of the Fund will continue to be met or will remain unchanged.

Roundhill Humanoid Robotics ETF | CHINA RISK  
Prospectus [Line Items]  
Risk [Text Block]

CHINA RISK. The Fund may invest in instruments that provide exposure to Chinese companies, including through investments in China A-Shares, which would subject the Fund to risks specific to China. China may be subject to considerable degrees of economic, political and social instability. China is an emerging market and demonstrates significantly higher volatility from time to time in comparison to developed markets. Over the last few decades, the Chinese government has undertaken reform of economic and market practices and has expanded the sphere of private ownership of property in China. However, Chinese markets generally continue to experience inefficiency, volatility and pricing anomalies resulting from governmental influence, a lack of publicly available information and/or political and social instability.

 

Chinese companies are also subject to the risk that Chinese authorities can intervene in their operations and structure. Internal social unrest or confrontations with neighboring countries, including military conflicts in response to such events, may also disrupt economic development in China and result in a greater risk of currency fluctuations, currency non-convertibility, interest rate fluctuations and higher rates of inflation.

 

China has experienced security concerns, such as terrorism and strained international relations. Additionally, China is alleged to have participated in state-sponsored cyberattacks against foreign companies and foreign governments. Actual and threatened responses to such activity and strained international relations, including purchasing restrictions, sanctions, tariffs or cyberattacks on the Chinese government or Chinese companies, may impact China’s economy and Chinese issuers of securities in which the Fund invests. Incidents involving China’s or the region’s security may cause uncertainty in Chinese markets and may adversely affect the Chinese economy and the Fund’s investments. Export growth continues to be a major driver of China’s rapid economic growth. Reduction in spending on Chinese products and services, supply chain diversification, institution of additional tariffs or other trade barriers (including as a result of heightened trade tensions or a trade war between China and the U.S. or in response to actual or alleged Chinese cyber activity) or a downturn in any of the economies of China’s key trading partners may have an adverse impact on the Chinese economy. The Fund’s portfolio may include companies that are subject to economic or trade restrictions (but not investment restrictions) imposed by the U.S. or other governments due to national security, human rights or other concerns of such government. So long as these restrictions do not include restrictions on investments, the Fund is generally expected to invest in such companies.

 

Chinese companies are not subject to the same degree of regulatory requirements, accounting standards or auditor oversight as companies in more developed countries. As a result, information about the Chinese securities in which the Fund invests may be less reliable or complete. Chinese companies with securities listed on U.S. exchanges may be delisted if they do not meet U.S. accounting standards and auditor oversight requirements, which would significantly decrease the liquidity and value of the securities. There may be significant obstacles to obtaining information necessary for investigations into or litigation against Chinese companies, and shareholders may have limited legal remedies. Chinese companies may also be subject to significantly weaker recordkeeping requirements than the requirements imposed upon U.S. companies.

Roundhill Humanoid Robotics ETF | CONSUMER DISCRETIONARY SECTOR RISK  
Prospectus [Line Items]  
Risk [Text Block]

CONSUMER DISCRETIONARY SECTOR RISK. Consumer discretionary companies, such as retailers, media companies and consumer services companies, provide non-essential goods and services. These companies manufacture products and provide discretionary services directly to the consumer, and the success of these companies is tied closely to the performance of the overall domestic and international economy, interest rates, competition and consumer confidence. Success depends heavily on disposable household income and consumer spending. Changes in demographics and consumer tastes can also affect the demand for, and success of, consumer discretionary products in the marketplace.

Roundhill Humanoid Robotics ETF | DEPOSITARY RECEIPTS RISK  
Prospectus [Line Items]  
Risk [Text Block]

DEPOSITARY RECEIPTS RISK. Depositary receipts may be less liquid than the underlying shares in their primary trading market. Any distributions paid to the holders of depositary receipts are usually subject to a fee charged by the depositary. Holders of depositary receipts may have limited voting rights, and investment restrictions in certain countries may adversely impact the value of depositary receipts because such restrictions may limit the ability to convert the equity shares into depositary receipts and vice versa. Such restrictions may cause the equity shares of the underlying issuer to trade at a discount or premium to the market price of the depositary receipts.

Roundhill Humanoid Robotics ETF | EMERGING MARKETS RISK  
Prospectus [Line Items]  
Risk [Text Block]

EMERGING MARKETS RISK. The Fund’s investments in China, including investment exposure to Chinese companies through investments in China A-Shares, may be subject to a greater risk of loss than investments in more developed markets. Emerging markets may be more likely to experience inflation, political turmoil and rapid changes in economic conditions than more developed markets. Emerging markets often have less uniformity in accounting and reporting requirements, unreliable securities valuation and greater risk associated with custody of securities.

Roundhill Humanoid Robotics ETF | EQUITY SECURITIES RISK

EQUITY SECURITIES RISK. Equity securities are subject to changes in value, and their values may be more volatile than those of other asset classes. Equity securities prices fluctuate for several reasons, including changes in investors’ perceptions of the financial condition of an issuer or the general condition of the relevant equity market, such as market volatility, or when political or economic events affecting an issuer occur. Common stock prices may be particularly sensitive to rising interest rates, as the cost of capital rises and borrowing costs increase.

Information technology companies are facing increased government and regulatory scrutiny and may be subject to adverse government or regulatory action.

Roundhill Humanoid Robotics ETF | INTERNATIONAL CLOSED MARKET TRADING RISK  
Prospectus [Line Items]  
Risk [Text Block]

INTERNATIONAL CLOSED MARKET TRADING RISK. To the extent securities held by the Fund trade on non-U.S. exchanges that are closed when the Fund’s primary listing exchange is open, there are likely to be deviations between the current price of an underlying security and the last quoted price for the underlying security (i.e., the Fund’s quote from the closed foreign market) used for purposes of calculating the Fund’s net asset value (“NAV”), resulting in premiums or discounts to the Fund’s NAV and bid/ask spreads that may be greater than those experienced by other funds. In addition, shareholders may not be able to purchase and sell shares of the Fund on days when the NAV of the Fund could be significantly affected by events in the relevant foreign markets.

Roundhill Humanoid Robotics ETF | ISSUER RISK

ISSUER RISK. The performance of the Fund depends on the performance of individual securities to which the Fund has exposure. Changes in the financial condition or credit rating of an issuer of those securities may cause the value of the securities to decline. There is no guarantee that an issuer that paid dividends in the past will continue to do so in the future or will continue paying dividends at the same level.

Roundhill Humanoid Robotics ETF | NON-U.S. SECURITIES RISK  
Prospectus [Line Items]  
Risk [Text Block]

NON-U.S. SECURITIES RISK. Non-U.S. securities are subject to higher volatility than securities of domestic issuers due to possible adverse political, social or economic developments, restrictions on foreign investment or exchange of securities, capital controls, lack of liquidity, currency exchange rates, excessive taxation, government seizure of assets, the imposition of sanctions by foreign governments, different legal or accounting standards, and less government supervision and regulation of securities exchanges in foreign countries.

Roundhill Humanoid Robotics ETF | VARIABLE INTEREST RISK  
Prospectus [Line Items]  
Risk [Text Block]

VARIABLE INTEREST RISK. Exposure to VIEs may pose additional risks because the investment is made in reference to an intermediary shell company that has entered into service and other contracts with the underlying Chinese operating company to provide investors with exposure to the operating company, but does not represent equity ownership in the operating company. As a result, such investment may limit the rights of an investor with respect to the underlying Chinese operating company. VIEs allow foreign shareholders to exert a degree of control over, and obtain economic benefits arising from, the operating company without formal legal ownership. However, the contractual arrangements between the shell company and the operating company may not be as effective in providing operational control as direct equity ownership, and a foreign investor's rights may be limited by, for example, actions of the Chinese government which could determine that the underlying contractual arrangements on which control of the VIE is based are invalid. The contractual arrangement on which the VIE structure is based would likely be subject to Chinese law and jurisdiction, which could raise questions about how recourse is sought. Investments through VIEs may be affected by conflicts of interest and duties between the legal owners of the VIE and the stockholders of the listed holding company, which could adversely impact the value of investments. VIEs are not formally recognized under Chinese law and investors face uncertainty about future actions by the Chinese government that could significantly affect the operating company’s financial performance and the enforceability of the contractual arrangements underlying the VIE structure. Prohibitions of these structures by the Chinese government, or the inability to enforce such contracts, from which the shell company derives its value, would likely cause the VIE-structured holding(s) to suffer significant losses, and in turn, adversely affect the Fund’s returns and net asset value.

Roundhill Humanoid Robotics ETF | MID CAPITALIZATION COMPANIES RISK  
Prospectus [Line Items]  
Risk [Text Block]

MID CAPITALIZATION COMPANIES RISK. Mid capitalization companies may be more vulnerable to adverse general market or economic developments, and their securities may be less liquid and may experience greater price volatility than larger, more established companies as a result of several factors, including limited trading volumes, fewer products or financial resources, management inexperience and less publicly available information. Accordingly, such companies are generally subject to greater market risk than larger, more established companies.

Roundhill Humanoid Robotics ETF | NEW FUND RISK  
Prospectus [Line Items]

SMALL CAPITALIZATION COMPANIES RISK. Small capitalization companies may be more vulnerable to adverse general market or economic developments, and their securities may be less liquid and may experience greater price volatility than large and mid capitalization companies as a result of several factors, including limited trading volumes, fewer products or financial resources, management inexperience and less publicly available information. Accordingly, such companies are generally subject to greater market risk than large and mid capitalization companies.

Roundhill Humanoid Robotics ETF | LINE OF BUSINESS RISK  
Prospectus [Line Items]  
Risk [Text Block]

LINE OF BUSINESS RISK. Certain companies included in the Fund’s portfolio will be engaged in other lines of business unrelated to the development of humanoid robotics, and these lines of business could adversely affect their operating results. The operating results of these companies may fluctuate as a result of these additional risks and events in the other lines of business. Despite a company’s possible success in activities linked to its development of humanoid robotics, there can be no assurance that the other lines of business in which these companies are engaged will not have an adverse effect on a company’s business or financial condition.

Roundhill Humanoid Robotics ETF | HUMANOID ROBOTICS COMPANIES RISK  
Prospectus [Line Items]  
Risk [Text Block]

HUMANOID ROBOTICS COMPANIES RISK. The Fund invests in Humanoid Robotics Companies, which may have limited product lines, markets, financial resources, or personnel and are subject to the risks of changes in business cycles, world economic growth, technological progress, and government regulation. These companies are also heavily dependent on intellectual property rights, and challenges to or misappropriation of such rights could have a material adverse effect on such companies. Securities of Humanoid Robotics Companies tend to be more volatile than securities of companies that rely less heavily on technology. Humanoid Robotics Companies typically engage in significant amounts of spending on research and development, and rapid changes to the field could have a material adverse effect on a company’s operating results. Additionally, the development and commercialization of fully-functional humanoid robots involve complex and evolving technologies, which may face unforeseen technical challenges, regulatory hurdles, and market acceptance issues. As a result, investments in Humanoid Robotics Companies may be subject to higher levels of risk and volatility.

Roundhill Humanoid Robotics ETF | ASIA RISK  
Prospectus [Line Items]  
Risk [Text Block]

ASIA RISK. The Fund invests significantly in the securities of Asian issuers. As such, the Fund is subject to certain risks specifically associated with investments in the securities of Asian issuers. Many Asian economies have experienced rapid growth and industrialization, and there is no assurance that this growth rate will be maintained. Some Asian economies are highly dependent on trade, and economic conditions in other countries within and outside Asia can impact these economies. Certain of these economies may be adversely affected by trade or policy disputes with its major trade partners. There is also a high concentration of market capitalization and trading volume in a small number of issuers representing a limited number of industries, as well as a high concentration of investors and financial intermediaries. Certain Asian countries have experienced and may in the future experience expropriation and nationalization of assets, confiscatory taxation, currency manipulation, political instability, armed conflict and social instability as a result of religious, ethnic, socio-economic and/or political unrest. In particular, escalated tensions involving North Korea and any outbreak of hostilities involving North Korea could have a severe adverse effect on Asian economies. Governments of certain Asian countries have exercised, and continue to exercise, substantial influence over many aspects of the private sector. In certain cases, the government owns or controls many companies, including the largest in the country. Accordingly, government actions could have a significant effect on the issuers of the Fund’s securities or on economic conditions generally. Recent developments in relations between the U.S. and China have heightened concerns of increased tariffs and restrictions on trade between the two countries. An increase in tariffs or trade restrictions, or even the threat of such developments, could lead to a significant reduction in international trade, which could have a negative impact on the economy of Asian countries and a commensurately negative impact on the Fund.

Roundhill Humanoid Robotics ETF | INDUSTRIALS SECTOR RISK  
Prospectus [Line Items]  
Risk [Text Block]

INDUSTRIALS SECTOR RISK. The value of securities issued by companies in the industrials sector may be adversely affected by supply and demand changes related to their specific products or services and industrials sector products in general. The products of manufacturing companies may face obsolescence due to rapid technological developments and frequent new product introduction. Global events, trade disputes and changes in government regulations, economic conditions and exchange rates may adversely affect the performance of companies in the industrials sector. Companies in the industrials sector may be adversely affected by liability for environmental damage and product liability claims. The industrials sector may also be adversely affected by changes or trends in commodity prices, which may be influenced by unpredictable factors. Companies in the industrials sector, particularly aerospace and defense companies, may also be adversely affected by government spending policies because companies in this sector tend to rely to a significant extent on government demand for their products and services.

NON-DIVERSIFICATION RISK. As a “non-diversified” fund, the Fund may hold a smaller number of portfolio securities than many other funds. To the extent the Fund invests in a relatively small number of issuers, a decline in the market value of a particular security held by the Fund may affect its value more than if it invested in a larger number of issuers. The value of the Fund Shares may be more volatile than the values of shares of more diversified funds.

MARKET RISK. Market risk is the risk that a particular investment, or Fund Shares in general, may fall in value. Securities are subject to market fluctuations caused by real or perceived adverse economic, political, and regulatory factors or market developments, changes in interest rates, disruptions to trade, impositions of tariffs and perceived trends in securities prices. Fund Shares could decline in value or underperform other investments. In addition, local, regional or global events such as war, acts of terrorism, market manipulation, government defaults, government shutdowns, regulatory actions, political changes, diplomatic developments, the imposition of sanctions and other similar measures, spread of infectious diseases or other public health issues, recessions, natural disasters, or other events could have a significant negative impact on the Fund and its investments. Any of such circumstances could have a materially negative impact on the value of Fund Shares, the liquidity of an investment, and may result in increased market volatility. During any such events, Fund Shares may trade at increased premiums or discounts to their net asset value, the bid/ask spread on Fund Shares may widen and the returns on investment may fluctuate.

Roundhill Top WeeklyPay™ ETF | CURRENT MARKET CONDITIONS RISK  
Prospectus [Line Items]  
Risk [Text Block]

CURRENT MARKET CONDITIONS RISK. Current market conditions risk is the risk that a particular investment, or Fund Shares in general, may fall in value due to current market conditions. As a means to fight inflation, which remains at elevated levels, the Federal Reserve and certain foreign central banks have raised interest rates; however, the Federal Reserve has recently lowered interest rates and may continue to do so. U.S. regulators have proposed several changes to market and issuer regulations which would directly impact the Fund, and any regulatory changes could adversely impact the Fund’s ability to achieve its investment strategies or make certain investments. Recent and potential future bank failures could result in disruption to the broader banking industry or markets generally and reduce confidence in financial institutions and the economy as a whole, which may also heighten market volatility and reduce liquidity. Additionally, challenges in commercial real estate markets, including rising interest rates, declining valuations and increasing vacancies, could have a broader impact on financial markets. The ongoing adversarial political climate in the United States, as well as political and diplomatic events both domestic and abroad, have and may continue to have an adverse impact the U.S. regulatory landscape, markets and investor behavior, which could have a negative impact on the Fund’s investments and operations. The change in administration resulting from the 2024 United States national elections could result in significant impacts to international trade relations, tax and immigration policies, and other aspects of the national and international political and financial landscape, which could affect, among other things, inflation and the securities markets generally. Other unexpected political, regulatory and diplomatic events within the U.S. and abroad may affect investor and consumer confidence and may adversely impact financial markets and the broader economy. For example, ongoing armed conflicts between Russia and Ukraine in Europe and among Israel, Iran, Hamas and other militant groups in the Middle East, have caused and could continue to cause significant market disruptions and volatility within the markets in Russia, Europe, the Middle East and the United States. The hostilities and sanctions resulting from those hostilities have and could continue to have a significant impact on certain Fund investments as well as Fund performance and liquidity. The economies of the United States and its trading partners, as well as the financial markets generally, may be adversely impacted by trade disputes, including the imposition of tariffs, and other matters. For example, the United States has imposed trade barriers and restrictions on China. In addition, the Chinese government is engaged in a longstanding dispute with Taiwan, continually threatening an invasion. If the political climate between the United States and China does not improve or continues to deteriorate, if China were to attempt invading Taiwan, or if other geopolitical conflicts develop or worsen, economies, markets and individual securities may be adversely affected, and the value of the Fund’s assets may go down. A public health crisis and the ensuing policies enacted by governments and central banks may cause significant volatility and uncertainty in global financial markets, negatively impacting global growth prospects. As the COVID-19 global pandemic illustrated, such events may affect certain geographic regions, countries, sectors and industries more significantly than others. Advancements in technology may also adversely impact markets and the overall performance of the Fund. For instance, the economy may be significantly impacted by the advanced development and increased regulation of artificial intelligence. Additionally, cyber security breaches of both government and non-government entities could have negative impacts on infrastructure and the ability of such entities, including the Fund, to operate properly. These events, and any other future events, may adversely affect the prices and liquidity of the Fund’s portfolio investments and could result in disruptions in the trading markets.

Roundhill Top WeeklyPay™ ETF | CYBERSECURITY RISK  
Prospectus [Line Items]  
Risk [Text Block]

CYBERSECURITY RISK. Failures or breaches of the electronic systems of the Fund, the Fund’s adviser, sub-adviser, distributor and other service providers, market makers, Authorized Participants or the issuers of securities in which the Fund invests have the ability to cause disruptions, negatively impact the Fund’s business operations and/or potentially result in financial losses to the Fund and its shareholders. While the Fund has established business continuity plans and risk management systems seeking to address system breaches or failures, there are inherent limitations in such plans and systems. Furthermore, the Fund cannot control the cybersecurity plans and systems of the Fund’s other service providers, market makers, Authorized Participants or issuers of securities in which the Fund invests.

Roundhill Top WeeklyPay™ ETF | DISTRIBUTION TAX RISK  
Prospectus [Line Items]  
Risk [Text Block]

DISTRIBUTION TAX RISK. The Fund currently expects to make distributions on a weekly basis. Such frequent distributions may expose investors to increased tax liabilities. However, these distributions may exceed the Fund’s income and gains for the Fund’s taxable year. Distributions in excess of the Fund’s current and accumulated earnings and profits will be treated as a return of capital. A return of capital distribution generally will not be taxable but will reduce the shareholder’s cost basis and will result in a higher capital gain or lower capital loss when those Fund Shares on which the distribution was received are sold. Once the Fund shareholder’s cost basis is reduced to zero, further distributions will be treated as capital gain if a Fund shareholder holds Fund Shares as capital assets. Additionally, any capital returned through distributions will be distributed after payment of Fund fees and expenses. Because a portion of the Fund’s distributions may consist of return of capital, the Fund may not be an appropriate investment for investors who do not want their principal investment in the Fund to decrease over time or who do not wish to receive return of capital in a given period. In the event that a shareholder purchases Fund Shares shortly before a distribution by the Fund, the entire distribution may be taxable to the shareholder even though a portion of the distribution effectively represents a return of the purchase price.

Roundhill Top WeeklyPay™ ETF | ETF RISK

ETF RISK. The Fund will invest in ETFs. The value of an ETF held by the Fund will fluctuate over time based on fluctuations in the values of the assets held by the ETF, which may be affected by changes in general economic conditions, expectations for future growth and profits, interest rates and the supply and demand for those assets. When the Fund invests in an ETF, it will bear a proportionate share of the ETF’s expenses. Brokerage, tax and other expenses may negatively impact the performance of the ETF and, in turn, the value of Fund Shares.

Roundhill Top WeeklyPay™ ETF | OPERATIONAL RISK  
Prospectus [Line Items]  
Risk [Text Block]

OPERATIONAL RISK. The Fund is subject to risks arising from various operational factors, including, but not limited to, human error, processing and communication errors, errors of the Fund’s service providers, counterparties or other third-parties, failed or inadequate processes and technology or systems failures. The Fund relies on third-parties for a range of services, including custody. Any delay or failure relating to engaging or maintaining such service providers may affect the Fund’s ability to meet its investment objective. Although the Fund and the Adviser seek to reduce these operational risks through controls and procedures, there is no way to completely protect against such risks.

Roundhill Top WeeklyPay™ ETF | STRUCTURAL ETF RISKS  
Prospectus [Line Items]  
Risk [Text Block]

STRUCTURAL ETF RISKS. The Fund is an ETF. Accordingly, it is subject to certain risks associated with its unique structure.

 

Active Market Risk. Although Fund Shares are listed for trading on the Exchange, there can be no assurance that an active trading market for Fund Shares will develop or be maintained. Fund Shares trade on the Exchange at market prices that may be below, at or above the Fund’s net asset value. Securities, including Fund Shares, are subject to market fluctuations and liquidity constraints that may be caused by such factors as economic, political, or regulatory developments, changes in interest rates, and/or perceived trends in securities prices. Fund Shares could decline in value or underperform other investments.

 

Market Participants Risk. Only an Authorized Participant may engage in creation or redemption transactions directly with the Fund, and none of those Authorized Participants is obligated to engage in creation and/or redemption transactions. The Fund has a limited number of institutions that may act as Authorized Participants on an agency basis (i.e., on behalf of other market participants). To the extent that Authorized Participants exit the business or are unable to proceed with creation or redemption orders with respect to the Fund and no other Authorized Participant is able to step forward to create or redeem, Fund Shares may be more likely to trade at a premium or discount to NAV and possibly face trading halts or delisting. The Fund may also rely on a small number of third-party market makers to provide a market for the purchase and sale of Fund Shares but such market makers are under no obligation to do so. Decisions by Authorized Participants or market makers to reduce their role or step away from these activities in times of market stress could inhibit the effectiveness of the arbitrage process in maintaining the relationship between the underlying values of the Fund’s portfolio securities and the Fund’s market price. Any trading halt or other problem relating to the trading activity of these market makers or any issues disrupting the Authorized Participants’ ability to proceed with creation and/or redemption orders could result in a dramatic change in the spread between the Fund’s net asset value and the price at which Fund Shares are trading on the Exchange, which could result in a decrease in value of Fund Shares. This reduced effectiveness could result in Fund Shares trading at a premium or discount to net asset value and also in greater than normal intraday bid-ask spreads Fund Shares.

 

Cash Transactions Risk. The Fund may effect a portion of its creations and redemptions for cash, rather than in-kind securities. Paying redemption proceeds in cash rather than through in-kind delivery of portfolio securities may require the Fund to dispose of or sell portfolio securities or other assets at an inopportune time to obtain the cash needed to meet redemption orders. This may cause the Fund to sell a security and recognize a capital gain or loss that might not have been incurred if it had made a redemption in-kind. As a result, the Fund may pay out higher or lower annual capital gains distributions than ETFs that redeem in-kind. The use of cash creations and redemptions may also cause the Fund Shares to trade in the market at greater bid-ask spreads or greater premiums or discounts to the Fund’s net asset value (“NAV”). Furthermore, the Fund may not be able to execute cash transactions for creation and redemption purposes at the same price used to determine the Fund’s NAV. To the extent that the maximum additional charge for creation or redemption transactions is insufficient to cover the execution shortfall, the Fund’s performance could be negatively impacted.

 

Costs of Buying and Selling Fund Shares. Due to the costs of buying or selling Fund Shares, including brokerage commissions imposed by brokers and bid/ask spreads, frequent trading of Fund Shares may significantly reduce investment results and an investment in Fund Shares may not be advisable for investors who anticipate regularly making small investments.

 

Premium/Discount Risk. As with all ETFs, Fund Shares may be bought and sold in the secondary market at market prices. The trading prices of Fund Shares in the secondary market may differ from the Fund’s daily NAV per Fund Share and there may be times when the market price of the Fund Shares is more than the NAV per Fund Share (premium) or less than the NAV per Fund Share (discount). If a shareholder purchases Fund Shares at a time when the market price is at a premium to the NAV or sells Fund Shares at a time when the market price is at a discount to the NAV, the shareholder may pay more for, or receive less than, the underlying value of the Fund Shares, respectively. This risk is heightened in times of market volatility or periods of steep market declines.

 

Trading Risks. Although Fund Shares are listed for trading on the Exchange and may be traded on U.S. exchanges other than the Exchange, there can be no assurance that Fund Shares will trade with any volume, or at all, on any stock exchange. In stressed market conditions, the liquidity of Fund Shares may begin to mirror the liquidity of the Fund’s underlying portfolio holdings, which can be significantly less liquid than Fund Shares. Trading in Fund Shares on the Exchange may be halted due to market conditions or for reasons that, in the view of the Exchange, make trading in Fund Shares inadvisable. In addition, trading in Fund Shares on the Exchange is subject to trading halts caused by extraordinary market volatility pursuant to the Exchange’s “circuit breaker” rules. There can be no assurance that the requirements of the Exchange necessary to maintain the listing of the Fund will continue to be met or will remain unchanged.

Roundhill Top WeeklyPay™ ETF | INFORMATION TECHNOLOGY COMPANIES RISK  
Prospectus [Line Items]  
Risk [Text Block]

INFORMATION TECHNOLOGY COMPANIES RISK. Information technology companies face intense competition, both domestically and internationally, which may have an adverse effect on profit margins. Like other technology companies, information technology companies may have limited product lines, markets, financial resources or personnel. The products of information technology companies may face obsolescence due to rapid technological developments, frequent new product introduction, unpredictable changes in growth rates and competition for the services of qualified personnel. Companies in the information technology sector are heavily dependent on patent and intellectual property rights. The loss or impairment of these rights may adversely affect the profitability of these companies. Information technology companies are facing increased government and regulatory scrutiny and may be subject to adverse government or regulatory action.

Roundhill Top WeeklyPay™ ETF | WEEKLYPAY™ FUNDS RISKS  
Prospectus [Line Items]  
Risk [Text Block]

WEEKLYPAY™ FUNDS RISKS. The Fund will have significant exposure to the WeeklyPay™ Funds. Accordingly, the Fund will be subject to the risks of the WeeklyPay™ Funds, set forth below. In addition to these risks, each WeeklyPay™ Fund is also subject to the following risks to which the Fund is also subject, which are described within the section entitled “Principal Risks”: Active Market Risk, Asset Class Risk, Cybersecurity Risk, Operational Risk and Structural ETF Risk.

 

COUNTERPARTY RISK. Fund transactions involving a counterparty are subject to the risk that the counterparty will not fulfill its obligation to the WeeklyPay™ Fund. Counterparty risk may arise because of the counterparty’s financial condition (i.e., financial difficulties, bankruptcy, or insolvency), market activities and developments, or other reasons, whether foreseen or not. A counterparty’s inability to fulfill its obligation may result in significant financial loss to the WeeklyPay™ Fund. The WeeklyPay™ Fund may be unable to recover its investment from the counterparty or may obtain a limited recovery, and/or recovery may be delayed.

 

DERIVATIVES RISK. The use of derivative instruments involves risks different from, or possibly greater than, the risks associated with investing directly in securities and other traditional investments. These risks include: (i) the risk that the counterparty to a derivative transaction may not fulfill its contractual obligations; (ii) risk of mispricing or improper valuation; and (iii) the risk that changes in the value of the derivative may not correlate perfectly with the underlying asset. Derivative prices are highly volatile and may fluctuate substantially during a short period of time. Such prices are influenced by numerous factors that affect the markets, including, but not limited to: changing supply and demand relationships; government programs and policies; national and international political and economic events, changes in interest rates, inflation and deflation and changes in supply and demand relationships. Trading derivative instruments involves risks different from, or possibly greater than, the risks associated with investing directly in securities. Derivative contracts ordinarily have leverage inherent in their terms. The use of leverage may cause a WeeklyPay™ Fund to liquidate portfolio positions when it would not be advantageous to do so in order to satisfy its obligations or to meet regulatory or contractual requirements for derivatives. The use of derivatives can magnify potential for gain or loss and, therefore, amplify the effects of market volatility on the Fund Share price.

 

EQUITY SECURITIES RISK. Equity securities are subject to changes in value, and their values may be more volatile than those of other asset classes. Equity securities prices fluctuate for several reasons, including changes in investors’ perceptions of the financial condition of an issuer or the general condition of the relevant equity market, such as market volatility, or when political or economic events affecting an issuer occur. Common stock prices may be particularly sensitive to rising interest rates, as the cost of capital rises and borrowing costs increase. Common stocks generally subject their holders to more risks than preferred stocks and debt securities because common stockholders’ claims are subordinated to those of holders of preferred stocks and debt securities upon the bankruptcy of the issuer.

 

FLEX OPTIONS RISK. Certain WeeklyPay™ Funds will utilize FLEX Options. Trading FLEX Options involves risks different from, or possibly greater than, the risks associated with investing directly in securities. A WeeklyPay™ Fund may experience losses from specific FLEX Option positions and certain FLEX Option positions may expire worthless. The FLEX Options are listed on an exchange; however, no one can guarantee that a liquid secondary trading market will exist for the FLEX Options. In the event that trading in the FLEX Options is limited or absent, the value of a WeeklyPay™ Fund’s FLEX Options may decrease. In a less liquid market for the FLEX Options, liquidating the FLEX Options may require the payment of a premium (for written FLEX Options) or acceptance of a discounted price (for purchased FLEX Options) and may take longer to complete. A less liquid trading market may adversely impact the value of the FLEX Options and WeeklyPay™ Fund shares and result in the Fund being unable to achieve its investment objective. Less liquidity in the trading of a WeeklyPay™ Fund’s FLEX Options could have an impact on the prices paid or received by a WeeklyPay™ Fund for the FLEX Options in connection with creations and redemptions of a WeeklyPay™ Fund’s shares. Depending on the nature of this impact to pricing, a WeeklyPay™ Fund may be forced to pay more for redemptions (or receive less for creations) than the price at which it currently values the FLEX Options. Such overpayment or under collection could reduce a WeeklyPay™ Fund’s ability to achieve its investment objectives. Additionally, in a less liquid market for the FLEX Options, the liquidation of a large number of options may more significantly impact the price. A less liquid trading market may adversely impact the value of the FLEX Options and the value of your investment. The trading in FLEX Options may be less deep and liquid than the market for certain other exchange-traded options, non-customized options or other securities.

 

INDIRECT INVESTMENT RISK. The Trust, the Fund, the WeeklyPay™ Funds, the Adviser, the Sub-Adviser nor any affiliates thereof are affiliated with an Applicable Security and are not involved with the offering of an Applicable Security in any way. An Applicable Security has no obligation to consider the Fund in taking any actions that might affect the value of the Fund. The Trust, the Fund, the Adviser, the Sub-Adviser or any affiliates thereof are not responsible for the performance of an Applicable Security and make no representation as to the performance of an Applicable Security. Investing in the Fund is not equivalent to investing in an Applicable Security. Fund shareholders will not have voting rights or rights to receive dividends or other distributions or any other rights with respect to an Applicable Security.

 

INFLATION RISK. Inflation risk is the risk that the value of assets or income from investments will be less in the future as inflation decreases the value of money. As inflation increases, the present value of a WeeklyPay™ Fund’s assets and distributions may decline. This risk is more prevalent with respect to fixed income securities held by a WeeklyPay™ Fund.

 

INTEREST RATE RISK. Interest rate risk is the risk that the value of the debt securities in a WeeklyPay™ Fund’s portfolio will decline because of rising market interest rates. Interest rate risk is generally lower for shorter term debt securities and higher for longer-term debt securities. Duration is a reasonably accurate measure of a debt security’s price sensitivity to changes in interest rates and a common measure of interest rate risk. Duration measures a debt security’s expected life on a present value basis, taking into account the debt security’s yield, interest payments and final maturity. In general, duration represents the expected percentage change in the value of a security for an immediate 1% change in interest rates. For example, the price of a debt security with a three-year duration would be expected to drop by approximately 3% in response to a 1% increase in interest rates. Therefore, prices of debt securities with shorter durations tend to be less sensitive to interest rate changes than debt securities with longer durations. As the value of a debt security changes over time, so will its duration.

 

ISSUER RISK. The performance of a WeeklyPay™ Fund depends on the performance of individual securities to which the WeeklyPay™ Fund has exposure. Changes in the financial condition or credit rating of an issuer of those securities may cause the value of the securities to decline. There is no guarantee that an issuer that paid dividends in the past will continue to do so in the future or will continue paying dividends at the same level.

 

LARGE CAPITALIZATION COMPANIES RISK. Large capitalization companies may be less able than smaller capitalization companies to adapt to changing market conditions. Large capitalization companies may be more mature and subject to more limited growth potential compared with smaller capitalization companies. During different market cycles, the performance of large capitalization companies has trailed the overall performance of the broader securities markets.

 

LEGISLATION AND LITIGATION RISK. Legislation or litigation that affects the value of assets or securities held by a WeeklyPay™ Fund may reduce the value of the WeeklyPay™ Fund. From time to time, various legislative initiatives are proposed that may have a negative impact on certain assets or securities in which a WeeklyPay™ Fund invests. In addition, litigation regarding any of the assets or securities owned by a WeeklyPay™ Fund may negatively impact the value of the Fund Shares. Such legislation or litigation may cause a WeeklyPay™ Fund to lose value or may result in higher portfolio turnover if the Adviser determines to sell such a holding.

 

LEVERAGE RISK. Each WeeklyPay™ Fund obtains investment exposure in excess of its net assets by utilizing leverage and may lose more money in market conditions that are adverse to its investment objective than a fund that does not utilize leverage. An investment in a WeeklyPay™ Fund is exposed to the risk that a decline in the weekly performance of shares of its Applicable Security will be magnified. This means that an investment in a WeeklyPay™ Fund will be reduced by an amount equal to 1.2% for every 1% weekly decline in the market value of the Applicable Security, not including the costs of financing leverage and other operating expenses, which would further reduce its value. A WeeklyPay™ Fund could theoretically lose an amount greater than its net assets in the event the market value of the Applicable Security declines more than 83.33% over a calendar week. Leverage will also have the effect of magnifying any differences in a WeeklyPay™ Fund’s correlation with its Applicable Security.

 

LIQUIDITY RISK. The market for swap agreements may be subject to periods of illiquidity. During such times it may be difficult or impossible to buy or sell a position at the desired price. Market disruptions or volatility can also make it difficult to find a counterparty willing to transact at a reasonable price and sufficient size. Illiquid markets may cause losses, which could be significant. The large size of the positions which a WeeklyPay™ Fund may acquire increases the risk of illiquidity, may make its positions more difficult to liquidate, and may increase the losses incurred while trying to do so.

 

MONEY MARKET INSTRUMENTS RISK. The value of money market instruments may be affected by changing interest rates and by changes in the credit ratings of the investments. If a significant amount of a WeeklyPay™ Fund’s assets are invested in money market instruments, it will be more difficult for a WeeklyPay™ Fund to achieve its investment objective. An investment in a money market fund is not insured or guaranteed by the FDIC or any other government agency. It is possible to lose money by investing in a money market fund.

 

SPECIAL TAX RISK. Each WeeklyPay™ Fund intends to qualify annually and to elect to be treated as a regulated investment company under the Code. To qualify for the favorable U.S. federal income tax treatment generally accorded to regulated investment companies, a WeeklyPay™ Fund must, among other things, (i) derive in each taxable year at least 90% of its gross income from dividends, interest, payments with respect to securities loans and gains from the sale or other disposition of stock, securities or foreign currencies or other income derived with respect to its business of investing in such stock, securities or currencies, or net income derived from interests in certain publicly traded partnerships; (ii) diversify its holdings so that, at the end of each quarter of the taxable year, (a) at least 50% of the market value of a WeeklyPay™ Fund’s assets is represented by cash and cash items (including receivables), U.S. government securities, the securities of other regulated investment companies and other securities, with such other securities of any one issuer generally limited for the purposes of this calculation to an amount not greater than 5% of the value of a WeeklyPay™ Fund’s total assets and not greater than 10% of the outstanding voting securities of such issuer, and (b) not more than 25% of the value of its total assets is invested in the securities (other than U.S. government securities or the securities of other regulated investment companies) of any one issuer, or two or more issuers which a WeeklyPay™ Fund controls which are engaged in the same, similar or related trades or businesses, or the securities of one or more of certain publicly traded partnerships; and (iii) distribute at least 90% of its investment company taxable income (which includes, among other items, dividends, interest and net short-term capital gains in excess of net long-term capital losses) and at least 90% of its net tax-exempt interest income each taxable year. There are certain exceptions for failure to qualify if the failure is for reasonable cause or is de minimis, and certain corrective action is taken and certain tax payments are made by a WeeklyPay™ Fund.

 

The Fund has based its analysis of its qualification as a RIC on the belief that its portfolio funds are themselves RICs. If a portfolio fund were to lose its status as a RIC, the Fund may fail its requirement to have a diversified portfolio, and, thus, lose its own RIC status.

 

The authority with regard to swaps entered into by regulated investment companies is unclear both as to the qualification under the income test and the identification of the issuer under the diversification test. Each WeeklyPay™ Fund intends to take the position that because the swaps held by the WeeklyPay™ WeeklyPay™ Fund reference securities that the income on the swaps are “other income” from the WeeklyPay™ Fund’s business of investing in stocks and securities. In addition, each WeeklyPay™ Fund intends to manage its investments in the swaps so that neither the exposure to issuer of the referenced Applicable Security nor the exposure to any one counterparty of the swaps will exceed 25% of the gross value of the WeeklyPay™ Fund’s portfolio at the end of any quarter.

 

If a WeeklyPay™ Fund were to fail to meet the qualifying income test or asset diversification test and fail to qualify as a RIC, it would be taxed in the same manner as an ordinary corporation, and distributions to its shareholders would not be deductible by a WeeklyPay™ Fund in computing its taxable income, which would adversely affect the WeeklyPay™ Fund’s performance.

 

A portion of the Fund’s distributions are expected to be treated as a return of capital for tax purposes.  Returns of capital distribution are not taxable income to you but reduce your tax basis in your Shares.  Such a reduction in tax basis will result in larger taxable gains and/or lower tax losses on a subsequent sale of Shares.  Shareholders who periodically receive the payment of dividends or other distributions consisting of a return of capital may be under the impression that they are receiving net profits from the Fund when, in fact, they are not.  You should not assume that the source of the distributions is from the net profits of the Fund.  If returns of capital exceed your tax basis, you will recognize gain as if you had sold the Shares.

 

SWAP AGREEMENTS RISK. Each WeeklyPay™ Fund will utilize swap agreements to derive its exposure to its Applicable Security. Swap agreements may involve greater risks than direct investment in securities as they may be leveraged and are subject to credit risk, counterparty risk and valuation risk. A swap agreement could result in losses if the underlying reference or asset does not perform as anticipated. In addition, many swaps trade over-the-counter and may be considered illiquid. It may not be possible for a WeeklyPay™ Fund to liquidate a swap position at an advantageous time or price, which may result in significant losses.

 

UNITED STATES RISK. Certain changes in the U.S. economy, such as when the U.S. economy weakens or when its financial markets decline, may have an adverse effect on the securities to which the WeeklyPay™ Fund has exposure.

 

U.S. GOVERNMENT SECURITIES RISK. U.S. government securities are subject to interest rate risk but generally do not involve the credit risks associated with investments in other types of debt securities. As a result, the yields available from U.S. government securities are generally lower than the yields available from other debt securities. U.S. government securities are guaranteed only as to the timely payment of interest and the payment of principal when held to maturity.

 

VALUATION RISK. The WeeklyPay™ Funds may hold securities or other assets that may be valued on the basis of factors other than market quotations. This may occur because the asset or security does not trade on a centralized exchange, or in times of market turmoil or reduced liquidity. There are multiple methods that can be used to value a portfolio holding when market quotations are not readily available. The value established for any portfolio holding at a point in time might differ from what would be produced using a different methodology or if it had been priced using market quotations. Portfolio holdings that are valued using techniques other than market quotations, including “fair valued” assets or securities, may be subject to greater fluctuation in their valuations from one day to the next than if market quotations were used. In addition, there is no assurance that a WeeklyPay™ Fund could sell or close out a portfolio position for the value established for it at any time, and it is possible that a WeeklyPay™ Fund would incur a loss because a portfolio position is sold or closed out at a discount to the valuation established by a WeeklyPay™ Fund at that time. A WeeklyPay™ Fund’s ability to value investments may be impacted by technological issues or errors by pricing services or other third-party service providers.

Roundhill Top WeeklyPay™ ETF | INDEX PROVIDER RISK

INDEX PROVIDER RISK. There is no assurance that the Index Provider, or any agents that act on its behalf, will compile the Index accurately, or that the Index will be determined, maintained, constructed, reconstituted, rebalanced, composed, calculated or disseminated accurately. The Index Provider and its agents do not provide any representation or warranty in relation to the quality, accuracy or completeness of data in the Index, and do not guarantee that the Index will be calculated in accordance with its stated methodology. The mandate of the Adviser and Sub-Adviser as described in this prospectus is to manage the Fund consistently with the Index provided by the Index Provider. The Adviser and Sub-Adviser rely upon the Index Provider and its agents to accurately compile, maintain, construct, reconstitute, rebalance, compose, calculate and disseminate the Index accurately. Therefore, losses or costs associated with any Index Provider or agent errors generally will be borne by the Fund and its shareholders. To correct any such error, the Index Provider or its agents may carry out an unscheduled rebalance of the Index or other modification of Index constituents or weightings. When the Fund in turn rebalances its portfolio, any transaction costs and market exposure arising from such portfolio rebalancing will be borne by the Fund and its shareholders. Unscheduled rebalances also expose the Fund to additional tracking error risk. Errors in respect of the quality, accuracy and completeness of the data used to compile the Index may occur from time to time and may not be identified and corrected by the Index Provider for a period of time or at all, particularly where the Index is less commonly used as a benchmark by funds or advisors. For example, during a period where the Index contains incorrect constituents, the Fund tracking the Index would have market exposure to such constituents and would be underexposed to the Index’s other constituents. Such errors may negatively impact the Fund and its shareholders. The Index Provider and its agents rely on various sources of information to assess the criteria of issuers included in the Index, including information that may be based on assumptions and estimates. Neither the Fund nor the Adviser can offer assurances that the Index’s calculation methodology or sources of information will provide an accurate assessment of included issuers. Unusual market conditions may cause the Index Provider to postpone a scheduled rebalance, which could cause the Index to vary from its normal or expected composition. The postponement of a scheduled rebalance in a time of market volatility could mean that constituents that would otherwise be removed at rebalance due to changes in market capitalizations, issuer credit ratings, or other reasons may remain, causing the performance and constituents of the Index to vary from those expected under normal conditions. Apart from scheduled rebalances, the Index Provider or its agents may carry out additional ad hoc rebalances to the Index due to unusual market conditions or in order, for example, to correct an error in the selection of Index constituents.

Roundhill Top WeeklyPay™ ETF | PASSIVE INVESTMENT RISK  
Prospectus [Line Items]  
Risk [Text Block]

PASSIVE INVESTMENT RISK. The Fund is not actively managed. The Fund invests in securities included in or representative of the Index regardless of investment merit. The Fund generally will not attempt to take defensive positions in declining markets. Additionally, the Fund’s return may not match the return of the Index for a number of reasons. The Fund incurs operating expenses not applicable to the Index, and may incur costs in buying and selling securities, especially when rebalancing the Fund’s portfolio holdings to reflect changes in the composition of the Index. The Fund’s portfolio holdings may not exactly replicate the securities included in the Index or the ratios between the securities included in the Index. Additionally, although the Fund follows a defined Index rebalance schedule, the Index Provider could determine to suspend or delay a rebalance to a market event, during which time the Fund’s index tracking error may be heightened and could negatively impact investors. Lastly, a stock included in the Index may not exhibit the factor trait or provide specific factor exposure for which it was selected, and consequently, the Fund’s holdings may not exhibit returns consistent with that factor trait.

NON-DIVERSIFICATION RISK. As a “non-diversified” fund, the Fund may hold a smaller number of portfolio securities than many other funds. To the extent the Fund invests in a relatively small number of issuers, a decline in the market value of a particular security held by the Fund may affect its value more than if it invested in a larger number of issuers. The value of the Fund Shares may be more volatile than the values of shares of more diversified funds.

Roundhill Inverse Dow 30 WeeklyPay™ ETF | MARKET RISK  
Prospectus [Line Items]  
Risk [Text Block]

MARKET RISK. Market risk is the risk that a particular investment, or Fund Shares in general, may fall in value. Securities are subject to market fluctuations caused by real or perceived adverse economic, political, and regulatory factors or market developments, changes in interest rates, disruptions to trade, impositions of tariffs and perceived trends in securities prices. Fund Shares could decline in value or underperform other investments. In addition, local, regional or global events such as war, acts of terrorism, market manipulation, government defaults, government shutdowns, regulatory actions, political changes, diplomatic developments, the imposition of sanctions and other similar measures, spread of infectious diseases or other public health issues, recessions, natural disasters, or other events could have a significant negative impact on the Fund and its investments. Any of such circumstances could have a materially negative impact on the value of Fund Shares, the liquidity of an investment, and may result in increased market volatility. During any such events, Fund Shares may trade at increased premiums or discounts to their net asset value, the bid/ask spread on Fund Shares may widen and the returns on investment may fluctuate.

Roundhill Inverse Dow 30 WeeklyPay™ ETF | LIQUIDITY RISK

Risk [Text Block]

LIQUIDITY RISK. The market for swap agreements that reference Dow 30 ETF shares may be subject to periods of illiquidity. During such times it may be difficult or impossible to buy or sell a position at the desired price. Market disruptions or volatility can also make it difficult to find a counterparty willing to transact at a reasonable price and sufficient size. Illiquid markets may cause losses, which could be significant. The large size of the positions which the Fund may acquire increases the risk of illiquidity, may make its positions more difficult to liquidate, and may increase the losses incurred while trying to do so. Such large positions also may impact the price of swap agreements on Dow 30 ETF shares.

Roundhill Inverse Dow 30 WeeklyPay™ ETF | ACTIVE MANAGEMENT RISK

Risk [Text Block]

ACTIVE MANAGEMENT RISK. The Fund is actively-managed and its performance reflects investment decisions that the Adviser and/or Sub-Adviser makes for the Fund. Such judgments about the Fund’s investments may prove to be incorrect. If the investments selected and the strategies employed by the Fund fail to produce the intended results, the Fund could underperform as compared to other funds with similar investment objectives and/or strategies, or could have negative returns.

Roundhill Inverse Dow 30 WeeklyPay™ ETF | ACTIVE MARKET RISK

ACTIVE MARKET RISK. Although Fund Shares are listed for trading on the Exchange, there can be no assurance that an active trading market for Fund Shares will develop or be maintained. Fund Shares trade on the Exchange at market prices that may be below, at or above the Fund’s net asset value. Securities, including Fund Shares, are subject to market fluctuations and liquidity constraints that may be caused by such factors as economic, political, or regulatory developments, changes in interest rates, and/or perceived trends in securities prices. Fund Shares could decline in value or underperform other investments.

Risk [Text Block]

CONCENTRATION RISK. The Fund is susceptible to an increased risk of loss, including losses due to adverse events that affect the Fund’s investments more than the market as a whole, to the extent that the Fund’s investments are concentrated in investments that provide exposure to the Dow 30 ETF and the industry or group of industries to which it is concentrated.

Roundhill Inverse Dow 30 WeeklyPay™ ETF | COUNTERPARTY RISK  
Prospectus [Line Items]  
Risk [Text Block]

COUNTERPARTY RISK. Fund transactions involving a counterparty are subject to the risk that the counterparty will not fulfill its obligation to the Fund. Counterparty risk may arise because of the counterparty’s financial condition (i.e., financial difficulties, bankruptcy, or insolvency), market activities and developments, or other reasons, whether foreseen or not. A counterparty’s inability to fulfill its obligation may result in significant financial loss to the Fund. The Fund may be unable to recover its investment from the counterparty or may obtain a limited recovery, and/or recovery may be delayed.

Roundhill Inverse Dow 30 WeeklyPay™ ETF | CURRENT MARKET CONDITIONS RISK  
Prospectus [Line Items]  
Risk [Text Block]

CURRENT MARKET CONDITIONS RISK. Current market conditions risk is the risk that a particular investment, or Fund Shares in general, may fall in value due to current market conditions. As a means to fight inflation, which remains at elevated levels, the Federal Reserve and certain foreign central banks have raised interest rates; however, the Federal Reserve has recently lowered interest rates and may continue to do so. U.S. regulators have proposed several changes to market and issuer regulations which would directly impact the Fund, and any regulatory changes could adversely impact the Fund’s ability to achieve its investment strategies or make certain investments. Recent and potential future bank failures could result in disruption to the broader banking industry or markets generally and reduce confidence in financial institutions and the economy as a whole, which may also heighten market volatility and reduce liquidity. Additionally, challenges in commercial real estate markets, including rising interest rates, declining valuations and increasing vacancies, could have a broader impact on financial markets. The ongoing adversarial political climate in the United States, as well as political and diplomatic events both domestic and abroad, have and may continue to have an adverse impact the U.S. regulatory landscape, markets and investor behavior, which could have a negative impact on the Fund’s investments and operations. The change in administration resulting from the 2024 United States national elections could result in significant impacts to international trade relations, tax and immigration policies, and other aspects of the national and international political and financial landscape, which could affect, among other things, inflation and the securities markets generally. Other unexpected political, regulatory and diplomatic events within the U.S. and abroad may affect investor and consumer confidence and may adversely impact financial markets and the broader economy. For example, ongoing armed conflicts between Russia and Ukraine in Europe and among Israel, Iran, Hamas and other militant groups in the Middle East, have caused and could continue to cause significant market disruptions and volatility within the markets in Russia, Europe, the Middle East and the United States. The hostilities and sanctions resulting from those hostilities have and could continue to have a significant impact on certain Fund investments as well as Fund performance and liquidity. The economies of the United States and its trading partners, as well as the financial markets generally, may be adversely impacted by trade disputes, including the imposition of tariffs, and other matters. For example, the United States has imposed trade barriers and restrictions on China. In addition, the Chinese government is engaged in a longstanding dispute with Taiwan, continually threatening an invasion. If the political climate between the United States and China does not improve or continues to deteriorate, if China were to attempt invading Taiwan, or if other geopolitical conflicts develop or worsen, economies, markets and individual securities may be adversely affected, and the value of the Fund’s assets may go down. A public health crisis and the ensuing policies enacted by governments and central banks may cause significant volatility and uncertainty in global financial markets, negatively impacting global growth prospects. As the COVID-19 global pandemic illustrated, such events may affect certain geographic regions, countries, sectors and industries more significantly than others. Advancements in technology may also adversely impact markets and the overall performance of the Fund. For instance, the economy may be significantly impacted by the advanced development and increased regulation of artificial intelligence. Additionally, cyber security breaches of both government and non-government entities could have negative impacts on infrastructure and the ability of such entities, including the Fund, to operate properly. These events, and any other future events, may adversely affect the prices and liquidity of the Fund’s portfolio investments and could result in disruptions in the trading markets.

Roundhill Inverse Dow 30 WeeklyPay™ ETF | CYBERSECURITY RISK  
Prospectus [Line Items]  
Risk [Text Block]

CYBERSECURITY RISK. Failures or breaches of the electronic systems of the Fund, the Fund’s adviser, sub-adviser, distributor and other service providers, market makers, Authorized Participants or the issuers of securities in which the Fund invests have the ability to cause disruptions, negatively impact the Fund’s business operations and/or potentially result in financial losses to the Fund and its shareholders. While the Fund has established business continuity plans and risk management systems seeking to address system breaches or failures, there are inherent limitations in such plans and systems. Furthermore, the Fund cannot control the cybersecurity plans and systems of the Fund’s other service providers, market makers, Authorized Participants or issuers of securities in which the Fund invests.

Roundhill Inverse Dow 30 WeeklyPay™ ETF | DEBT SECURITIES RISK  
Prospectus [Line Items]  
Risk [Text Block]

DEBT SECURITIES RISK. Investments in debt securities subject the holder to the credit risk of the issuer. Credit risk refers to the possibility that the issuer or other obligor of a security will not be able or willing to make payments of interest and principal when due. Generally, the value of debt securities will change inversely with changes in interest rates. To the extent that interest rates rise, certain underlying obligations may be paid off substantially slower than originally anticipated and the value of those securities may fall sharply. During periods of falling interest rates, the income received by the Fund may decline. If the principal on a debt security is prepaid before expected, the prepayments of principal may have to be reinvested in obligations paying interest at lower rates. Debt securities generally do not trade on a securities exchange making them generally less liquid and more difficult to value than common stock.

Roundhill Inverse Dow 30 WeeklyPay™ ETF | DERIVATIVES RISK  
Prospectus [Line Items]  
Risk [Text Block]

DERIVATIVES RISK. The use of derivative instruments involves risks different from, or possibly greater than, the risks associated with investing directly in securities and other traditional investments. These risks include: (i) the risk that the counterparty to a derivative transaction may not fulfill its contractual obligations; (ii) risk of mispricing or improper valuation; and (iii) the risk that changes in the value of the derivative may not correlate perfectly with the underlying asset. Derivative prices are highly volatile and may fluctuate substantially during a short period of time. Such prices are influenced by numerous factors that affect the markets, including, but not limited to: changing supply and demand relationships; government programs and policies; national and international political and economic events, changes in interest rates, inflation and deflation and changes in supply and demand relationships. Trading derivative instruments involves risks different from, or possibly greater than, the risks associated with investing directly in securities. Derivative contracts ordinarily have leverage inherent in their terms. The use of leverage may cause the Fund to liquidate portfolio positions when it would not be advantageous to do so in order to satisfy its obligations or to meet regulatory or contractual requirements for derivatives. The use of derivatives can magnify potential for gain or loss and, therefore, amplify the effects of market volatility on the Fund Share price.

Roundhill Inverse Dow 30 WeeklyPay™ ETF | DISTRIBUTION TAX RISK  
Prospectus [Line Items]  
Risk [Text Block]

DISTRIBUTION TAX RISK. The Fund currently expects to make distributions on a weekly basis. Such frequent distributions may expose investors to increased tax liabilities. However, these distributions may exceed the Fund’s income and gains for the Fund’s taxable year. Distributions in excess of the Fund’s current and accumulated earnings and profits will be treated as a return of capital. A return of capital distribution generally will not be taxable but will reduce the shareholder’s cost basis and will result in a higher capital gain or lower capital loss when those Fund Shares on which the distribution was received are sold. Once the Fund shareholder’s cost basis is reduced to zero, further distributions will be treated as capital gain if the Fund shareholder holds Fund Shares as capital assets. Additionally, any capital returned through distributions will be distributed after payment of Fund fees and expenses. Because a portion of the Fund’s distributions may consist of return of capital, the Fund may not be an appropriate investment for investors who do not want their principal investment in the Fund to decrease over time or who do not wish to receive return of capital in a given period. In the event that a shareholder purchases Fund Shares shortly before a distribution by the Fund, the entire distribution may be taxable to the shareholder even though a portion of the distribution effectively represents a return of the purchase price.

Roundhill Inverse Dow 30 WeeklyPay™ ETF | ETF RISK  
Prospectus [Line Items]  
Risk [Text Block]

ETF RISK. The Fund may invest in ETFs. The value of an ETF held by the Fund will fluctuate over time based on fluctuations in the values of the assets held by the ETF, which may be affected by changes in general economic conditions, expectations for future growth and profits, interest rates and the supply and demand for those assets. When the Fund invests in an ETF, it will bear a proportionate share of the ETF’s expenses. Brokerage, tax and other expenses may negatively impact the performance of the ETF and, in turn, the value of the Fund Shares. An ETF that tracks an index may not exactly match the performance of the index due to cash drag, differences between the portfolio of the ETF and the components of the index, expenses and other factors.

Roundhill Inverse Dow 30 WeeklyPay™ ETF | INFLATION RISK  
Prospectus [Line Items]  
Risk [Text Block]

INFLATION RISK. Inflation risk is the risk that the value of assets or income from investments will be less in the future as inflation decreases the value of money. As inflation increases, the present value of the Fund’s assets and distributions may decline. This risk is more prevalent with respect to fixed income securities held by the Fund.

Roundhill Inverse Dow 30 WeeklyPay™ ETF | Interest Rate Risk [Member]  
Prospectus [Line Items]  
Risk [Text Block]

INTEREST RATE RISK. Interest rate risk is the risk that the value of the debt securities in the Fund’s portfolio will decline because of rising market interest rates. Interest rate risk is generally lower for shorter term debt securities and higher for longer-term debt securities. Duration is a reasonably accurate measure of a debt security’s price sensitivity to changes in interest rates and a common measure of interest rate risk. Duration measures a debt security’s expected life on a present value basis, taking into account the debt security’s yield, interest payments and final maturity. In general, duration represents the expected percentage change in the value of a security for an immediate 1% change in interest rates. For example, the price of a debt security with a three-year duration would be expected to drop by approximately 3% in response to a 1% increase in interest rates. Therefore, prices of debt securities with shorter durations tend to be less sensitive to interest rate changes than debt securities with longer durations. As the value of a debt security changes over time, so will its duration.

Roundhill Inverse Dow 30 WeeklyPay™ ETF | LEGISLATION AND LITIGATION RISK  
Prospectus [Line Items]  
Risk [Text Block]

LEGISLATION AND LITIGATION RISK. Legislation or litigation that affects the value of assets or securities held by the Fund may reduce the value of the Fund. From time to time, various legislative initiatives are proposed that may have a negative impact on certain assets or securities in which the Fund invests. In addition, litigation regarding any of the assets or securities owned by the Fund may negatively impact the value of the Fund Shares. Such legislation or litigation may cause the Fund to lose value or may result in higher portfolio turnover if the Adviser determines to sell such a holding.

Roundhill Inverse Dow 30 WeeklyPay™ ETF | LEVERAGE RISK  
Prospectus [Line Items]  
Risk [Text Block]

LEVERAGE RISK. The Fund obtains investment exposure in excess of its net assets by utilizing leverage and may lose more money in market conditions that are adverse to its investment objectives than a fund that does not utilize leverage. An investment in the Fund is exposed to the risk that an increase in the weekly performance of shares of the Dow 30 ETF will be magnified. This means that an investment in the Fund will be reduced by an amount equal to 1.2% for every 1% weekly increase in the market value of Dow 30 ETF shares, not including the costs of financing leverage and other operating expenses, which would further reduce its value. The Fund could theoretically lose an amount greater than its net assets in the event the market value of Dow 30 ETF shares increase more than 83.33% over a calendar week. Leverage will also have the effect of magnifying any differences in the Fund’s correlation with Dow 30 ETF shares.

Roundhill Inverse Dow 30 WeeklyPay™ ETF | MONEY MARKET INSTRUMENTS RISK  
Prospectus [Line Items]  
Risk [Text Block]

MONEY MARKET INSTRUMENTS RISK. The value of money market instruments may be affected by changing interest rates and by changes in the credit ratings of the investments. If a significant amount of the Fund’s assets are invested in money market instruments, it will be more difficult for the Fund to achieve its investment objectives. An investment in a money market fund is not insured or guaranteed by the FDIC or any other government agency. It is possible to lose money by investing in a money market fund.

Roundhill Inverse Dow 30 WeeklyPay™ ETF | OPERATIONAL RISK  
Prospectus [Line Items]  
Risk [Text Block]

OPERATIONAL RISK. The Fund is subject to risks arising from various operational factors, including, but not limited to, human error, processing and communication errors, errors of the Fund’s service providers, counterparties or other third-parties, failed or inadequate processes and technology or systems failures. The Fund relies on third-parties for a range of services, including custody. Any delay or failure relating to engaging or maintaining such service providers may affect the Fund’s ability to meet its investment objectives. Although the Fund and the Adviser seek to reduce these operational risks through controls and procedures, there is no way to completely protect against such risks.

Roundhill Inverse Dow 30 WeeklyPay™ ETF | SPECIAL TAX RISK  
Prospectus [Line Items]  
Risk [Text Block]

SPECIAL TAX RISK. The Fund intends to qualify annually and to elect to be treated as a regulated investment company under the Internal Revenue Code of 1986, as amended (the “Code”). To qualify for the favorable U.S. federal income tax treatment generally accorded to regulated investment companies, the Fund must, among other things, (i) derive in each taxable year at least 90% of its gross income from dividends, interest, payments with respect to securities loans and gains from the sale or other disposition of stock, securities or foreign currencies or other income derived with respect to its business of investing in such stock, securities or currencies, or net income derived from interests in certain publicly traded partnerships; (ii) diversify its holdings so that, at the end of each quarter of the taxable year, (a) at least 50% of the market value of the Fund’s assets is represented by cash and cash items (including receivables), U.S. government securities, the securities of other regulated investment companies and other securities, with such other securities of any one issuer generally limited for the purposes of this calculation to an amount not greater than 5% of the value of the Fund’s total assets and not greater than 10% of the outstanding voting securities of such issuer, and (b) not more than 25% of the value of its total assets is invested in the securities (other than U.S. government securities or the securities of other regulated investment companies) of any one issuer, or two or more issuers which the Fund controls which are engaged in the same, similar or related trades or businesses, or the securities of one or more of certain publicly traded partnerships; and (iii) distribute at least 90% of its investment company taxable income (which includes, among other items, dividends, interest and net short-term capital gains in excess of net long-term capital losses) and at least 90% of its net tax-exempt interest income each taxable year. There are certain exceptions for failure to qualify if the failure is for reasonable cause or is de minimis, and certain corrective action is taken and certain tax payments are made by the Fund.

 

The authority with regard to swaps entered into by regulated investment companies is unclear both as to the qualification under the income test and the identification of the issuer under the diversification test. The Fund intends to take the position that because the swaps held by the Fund reference securities that the income on the swaps are “other income” from the Fund’s business of investing in stocks and securities. In addition, the Fund intends to manage its investments in the swaps so that neither the exposure to issuer of the referenced security nor the exposure to any one counterparty of the swaps will exceed 25% of the gross value of the Fund’s portfolio at the end of any quarter.

 

If the Fund were to fail to meet the qualifying income test or asset diversification test and fail to qualify as a RIC, it would be taxed in the same manner as an ordinary corporation, and distributions to its shareholders would not be deductible by the Fund in computing its taxable income, which would adversely affect the Fund’s performance.

Roundhill Inverse Dow 30 WeeklyPay™ ETF | STRUCTURAL ETF RISKS  
Prospectus [Line Items]  
Risk [Text Block]

STRUCTURAL ETF RISKS. The Fund is an ETF. Accordingly, it is subject to certain risks associated with its unique structure.

 

Market Participants Risk. Only an Authorized Participant may engage in creation or redemption transactions directly with the Fund, and none of those Authorized Participants is obligated to engage in creation and/or redemption transactions. The Fund has a limited number of institutions that may act as Authorized Participants on an agency basis (i.e., on behalf of other market participants). To the extent that Authorized Participants exit the business or are unable to proceed with creation or redemption orders with respect to the Fund and no other Authorized Participant is able to step forward to create or redeem, Fund Shares may be more likely to trade at a premium or discount to NAV and possibly face trading halts or delisting. The Fund may also rely on a small number of third-party market makers to provide a market for the purchase and sale of Fund Shares but such market makers are under no obligation to do so. Decisions by Authorized Participants or market makers to reduce their role or step away from these activities in times of market stress could inhibit the effectiveness of the arbitrage process in maintaining the relationship between the underlying values of the Fund’s portfolio securities and the Fund’s market price. Any trading halt or other problem relating to the trading activity of these market makers or any issues disrupting the Authorized Participants’ ability to proceed with creation and/or redemption orders could result in a dramatic change in the spread between the Fund’s net asset value and the price at which Fund Shares are trading on the Exchange, which could result in a decrease in value of Fund Shares. This reduced effectiveness could result in Fund Shares trading at a premium or discount to net asset value and also in greater than normal intraday bid-ask spreads Fund Shares.

 

Cash Transactions Risk. The Fund currently expects to effect a significant portion of its creations and redemptions for cash, rather than in-kind securities. Paying redemption proceeds in cash rather than through in-kind delivery of portfolio securities may require the Fund to dispose of or sell portfolio securities or other assets at an inopportune time to obtain the cash needed to meet redemption orders. This may cause the Fund to sell a security and recognize a capital gain or loss that might not have been incurred if it had made a redemption in-kind. As a result, the Fund may pay out higher or lower annual capital gains distributions than ETFs that redeem in-kind. The use of cash creations and redemptions may also cause the Fund’s Shares to trade in the market at greater bid-ask spreads or greater premiums or discounts to the Fund’s net asset value (“NAV”). Furthermore, the Fund may not be able to execute cash transactions for creation and redemption purposes at the same price used to determine the Fund’s NAV. To the extent that the maximum additional charge for creation or redemption transactions is insufficient to cover the execution shortfall, the Fund’s performance could be negatively impacted.

 

Costs of Buying and Selling Fund Shares. Due to the costs of buying or selling Fund Shares, including brokerage commissions imposed by brokers and bid/ask spreads, frequent trading of Fund Shares may significantly reduce investment results and an investment in Fund Shares may not be advisable for investors who anticipate regularly making small investments.

 

Premium/Discount Risk. As with all ETFs, Fund Shares may be bought and sold in the secondary market at market prices. The trading prices of Fund Shares in the secondary market may differ from the Fund’s daily NAV per Fund Share and there may be times when the market price of the Fund Shares is more than the NAV per Fund Share (premium) or less than the NAV per Fund Share (discount). If a shareholder purchases Fund Shares at a time when the market price is at a premium to the NAV or sells Fund Shares at a time when the market price is at a discount to the NAV, the shareholder may pay more for, or receive less than, the underlying value of the Fund Shares, respectively. This risk is heightened in times of market volatility or periods of steep market declines.

 

Trading Risks. Although Fund Shares are listed for trading on the Exchange and may be traded on U.S. exchanges other than the Exchange, there can be no assurance that Fund Shares will trade with any volume, or at all, on any stock exchange. In stressed market conditions, the liquidity of Fund Shares may begin to mirror the liquidity of the Fund’s underlying portfolio holdings, which can be significantly less liquid than Fund Shares. Trading in Fund Shares on the Exchange may be halted due to market conditions or for reasons that, in the view of the Exchange, make trading in Fund Shares inadvisable. In addition, trading in Fund Shares on the Exchange is subject to trading halts caused by extraordinary market volatility pursuant to the Exchange’s “circuit breaker” rules. There can be no assurance that the requirements of the Exchange necessary to maintain the listing of the Fund will continue to be met or will remain unchanged.

Roundhill Inverse Dow 30 WeeklyPay™ ETF | U.S. GOVERNMENT SECURITIES RISK  
Prospectus [Line Items]  
Risk [Text Block]

U.S. GOVERNMENT SECURITIES RISK. U.S. government securities are subject to interest rate risk but generally do not involve the credit risks associated with investments in other types of debt securities. As a result, the yields available from U.S. government securities are generally lower than the yields available from other debt securities. U.S. government securities are guaranteed only as to the timely payment of interest and the payment of principal when held to maturity.

Roundhill Inverse Dow 30 WeeklyPay™ ETF | VALUATION RISK  
Prospectus [Line Items]  
Risk [Text Block]

VALUATION RISK. The Fund may hold securities or other assets that may be valued on the basis of factors other than market quotations. This may occur because the asset or security does not trade on a centralized exchange, or in times of market turmoil or reduced liquidity. There are multiple methods that can be used to value a portfolio holding when market quotations are not readily available. The value established for any portfolio holding at a point in time might differ from what would be produced using a different methodology or if it had been priced using market quotations. Portfolio holdings that are valued using techniques other than market quotations, including “fair valued” assets or securities, may be subject to greater fluctuation in their valuations from one day to the next than if market quotations were used. In addition, there is no assurance that the Fund could sell or close out a portfolio position for the value established for it at any time, and it is possible that the Fund would incur a loss because a portfolio position is sold or closed out at a discount to the valuation established by the Fund at that time. The Fund’s ability to value investments may be impacted by technological issues or errors by pricing services or other third-party service providers.

Roundhill Inverse Dow 30 WeeklyPay™ ETF | SWAP AGREEMENTS RISK  
Prospectus [Line Items]  
Risk [Text Block]

SWAP AGREEMENTS RISK. The Fund will utilize swap agreements to derive its exposure to shares of the Dow 30 ETF. Swap agreements may involve greater risks than direct investment in securities as they may be leveraged and are subject to credit risk, counterparty risk and valuation risk. A swap agreement could result in losses if the underlying reference or asset does not perform as anticipated. In addition, many swaps trade over-the-counter and may be considered illiquid. It may not be possible for the Fund to liquidate a swap position at an advantageous time or price, which may result in significant losses.

Roundhill Inverse Dow 30 WeeklyPay™ ETF | NEW FUND RISK  
Prospectus [Line Items]

NEW FUND RISK. The Fund is a recently organized investment company with a limited operating history. As a result, prospective investors have a limited track record or history on which to base their investment decision.

Roundhill Inverse Dow 30 WeeklyPay™ ETF | INVERSE CORRELATION RISK  
Prospectus [Line Items]  
Risk [Text Block]

INVERSE CORRELATION RISK. The Fund seeks to provide a return equal to -1.2 times (-120%) the calendar week total return of shares of the Dow 30 ETF. This means that the Fund will decrease in value when the Dow 30 ETF increases in value, a result which is the opposite of traditional funds. The more that the Dow 30 ETF increases in value over a given day, the more the Fund will decrease in value.

Roundhill Inverse Dow 30 WeeklyPay™ ETF | DOW 30 INVESTING RISKS  
Prospectus [Line Items]  
Risk [Text Block]

DOW 30 INVESTING RISKS. The Fund will have significant exposure to the Dow 30 ETF through its investments in shares of the Dow 30 ETF and swap agreements that utilize the Dow 30 ETF as the reference asset. Accordingly, the Fund will be subject to the risks of the Dow 30 ETF, set forth below. In addition to these risks, the Dow 30 ETF is also subject to the following risks to which the Fund is also subject, which are described within the section entitled “Principal Risks”: Market Risk, Asset Class Risk, Concentration Risk, Current Market Conditions Risk, Cybersecurity Risk, Operational Risk and Structural ETF Risk.

 

EQUITY SECURITIES RISK. Equity securities are subject to changes in value, and their values may be more volatile than those of other asset classes. Equity securities prices fluctuate for several reasons, including changes in investors’ perceptions of the financial condition of an issuer or the general condition of the relevant equity market, such as market volatility, or when political or economic events affecting an issuer occur. Common stock prices may be particularly sensitive to rising interest rates, as the cost of capital rises and borrowing costs increase. Common stocks generally subject their holders to more risks than preferred stocks and debt securities because common stockholders’ claims are subordinated to those of holders of preferred stocks and debt securities upon the bankruptcy of the issuer.

 

INDEX-RELATED RISK. The Dow 30 ETF Index Provider may rely on various sources of information to assess the criteria of components of the Dow 30 ETF Index, including information that may be based on assumptions and estimates. Neither the Dow 30 ETF nor its investment adviser offer assurances that the Dow 30 ETF Index Provider’s methodology or sources of information will provide an accurate assessment of included components or will result in the Dow 30 ETF meeting its investment objective. Errors in index data, index computations or the construction of the Dow 30 ETF Index in accordance with its methodology may occur, and the Dow 30 ETF Index Provider may not identify or correct them promptly or at all, which may have an adverse impact on the Dow 30 ETF and its shareholders. Unusual market conditions or other unforeseen circumstances (such as natural disasters, political unrest or war) may impact the Dow 30 ETF Index Provider or a third-party data provider and could cause the Dow 30 ETF Index Provider to postpone a scheduled rebalance. This could cause the Dow 30 ETF Index to vary from its normal or expected composition.

 

INDIRECT INVESTMENT RISK. The Dow 30 ETF is not affiliated with the Trust, the Fund, the Adviser, the Sub-Adviser or any affiliates thereof and is not involved with this offering in any way, and has no obligation to consider the Fund in taking any actions that might affect the value of the Fund. The Trust, the Fund, the Adviser, the Sub-Adviser or any affiliate are not responsible for the performance of the Dow 30 ETF and make no representation as to the performance of the Dow 30 ETF. Investing in the Fund is not equivalent to investing in the Dow 30 ETF Fund. Shareholders will not have voting rights or rights to receive dividends or other distributions or any other rights with respect to the Dow 30 ETF.

 

LARGE CAPITALIZATION COMPANIES RISK. Large capitalization companies may be less able than smaller capitalization companies to adapt to changing market conditions. Large capitalization companies may be more mature and subject to more limited growth potential compared with smaller capitalization companies. During different market cycles, the performance of large capitalization companies has trailed the overall performance of the broader securities markets.

 

UNITED STATES RISK. Certain changes in the U.S. economy, such as when the U.S. economy weakens or when its financial markets decline, may have an adverse effect on the securities to which the Fund has exposure.

To the extent the Fund invests in a relatively small number of issuers, a decline in the market value of a particular security held by the Fund may affect its value more than if it invested in a larger number of issuers. The value of the Fund Shares may be more volatile than the values of shares of more diversified funds.

MARKET RISK. Market risk is the risk that a particular investment, or Fund Shares in general, may fall in value. Securities are subject to market fluctuations caused by real or perceived adverse economic, political, and regulatory factors or market developments, changes in interest rates, disruptions to trade, impositions of tariffs and perceived trends in securities prices. Fund Shares could decline in value or underperform other investments. In addition, local, regional or global events such as war, acts of terrorism, market manipulation, government defaults, government shutdowns, regulatory actions, political changes, diplomatic developments, the imposition of sanctions and other similar measures, spread of infectious diseases or other public health issues, recessions, natural disasters, or other events could have a significant negative impact on the Fund and its investments. Any of such circumstances could have a materially negative impact on the value of Fund Shares, the liquidity of an investment, and may result in increased market volatility. During any such events, Fund Shares may trade at increased premiums or discounts to their net asset value, the bid/ask spread on Fund Shares may widen and the returns on investment may fluctuate.

Roundhill Inverse Russell 2000 WeeklyPay™ ETF | LIQUIDITY RISK

Risk [Text Block]

LIQUIDITY RISK. The market for swap agreements that reference Russell 2000 ETF shares may be subject to periods of illiquidity. During such times it may be difficult or impossible to buy or sell a position at the desired price. Market disruptions or volatility can also make it difficult to find a counterparty willing to transact at a reasonable price and sufficient size. Illiquid markets may cause losses, which could be significant. The large size of the positions which the Fund may acquire increases the risk of illiquidity, may make its positions more difficult to liquidate, and may increase the losses incurred while trying to do so. Such large positions also may impact the price of swap agreements on Russell 2000 ETF shares.

Roundhill Inverse Russell 2000 WeeklyPay™ ETF | ACTIVE MANAGEMENT RISK

ACTIVE MANAGEMENT RISK. The Fund is actively-managed and its performance reflects investment decisions that the Adviser and/or Sub-Adviser makes for the Fund. Such judgments about the Fund’s investments may prove to be incorrect. If the investments selected and the strategies employed by the Fund fail to produce the intended results, the Fund could underperform as compared to other funds with similar investment objectives and/or strategies, or could have negative returns.

ACTIVE MARKET RISK. Although Fund Shares are listed for trading on the Exchange, there can be no assurance that an active trading market for Fund Shares will develop or be maintained. Fund Shares trade on the Exchange at market prices that may be below, at or above the Fund’s net asset value. Securities, including Fund Shares, are subject to market fluctuations and liquidity constraints that may be caused by such factors as economic, political, or regulatory developments, changes in interest rates, and/or perceived trends in securities prices. Fund Shares could decline in value or underperform other investments.

CONCENTRATION RISK. The Fund is susceptible to an increased risk of loss, including losses due to adverse events that affect the Fund’s investments more than the market as a whole, to the extent that the Fund’s investments are concentrated in investments that provide exposure to the Russell 2000 ETF and the industry or group of industries to which it is concentrated.

COUNTERPARTY RISK. Fund transactions involving a counterparty are subject to the risk that the counterparty will not fulfill its obligation to the Fund. Counterparty risk may arise because of the counterparty’s financial condition (i.e., financial difficulties, bankruptcy, or insolvency), market activities and developments, or other reasons, whether foreseen or not. A counterparty’s inability to fulfill its obligation may result in significant financial loss to the Fund. The Fund may be unable to recover its investment from the counterparty or may obtain a limited recovery, and/or recovery may be delayed.

Roundhill Inverse Russell 2000 WeeklyPay™ ETF | CURRENT MARKET CONDITIONS RISK  
Prospectus [Line Items]  
Risk [Text Block]

CURRENT MARKET CONDITIONS RISK. Current market conditions risk is the risk that a particular investment, or Fund Shares in general, may fall in value due to current market conditions. As a means to fight inflation, which remains at elevated levels, the Federal Reserve and certain foreign central banks have raised interest rates; however, the Federal Reserve has recently lowered interest rates and may continue to do so. U.S. regulators have proposed several changes to market and issuer regulations which would directly impact the Fund, and any regulatory changes could adversely impact the Fund’s ability to achieve its investment strategies or make certain investments. Recent and potential future bank failures could result in disruption to the broader banking industry or markets generally and reduce confidence in financial institutions and the economy as a whole, which may also heighten market volatility and reduce liquidity. Additionally, challenges in commercial real estate markets, including rising interest rates, declining valuations and increasing vacancies, could have a broader impact on financial markets. The ongoing adversarial political climate in the United States, as well as political and diplomatic events both domestic and abroad, have and may continue to have an adverse impact the U.S. regulatory landscape, markets and investor behavior, which could have a negative impact on the Fund’s investments and operations. The change in administration resulting from the 2024 United States national elections could result in significant impacts to international trade relations, tax and immigration policies, and other aspects of the national and international political and financial landscape, which could affect, among other things, inflation and the securities markets generally. Other unexpected political, regulatory and diplomatic events within the U.S. and abroad may affect investor and consumer confidence and may adversely impact financial markets and the broader economy. For example, ongoing armed conflicts between Russia and Ukraine in Europe and among Israel, Iran, Hamas and other militant groups in the Middle East, have caused and could continue to cause significant market disruptions and volatility within the markets in Russia, Europe, the Middle East and the United States. The hostilities and sanctions resulting from those hostilities have and could continue to have a significant impact on certain Fund investments as well as Fund performance and liquidity. The economies of the United States and its trading partners, as well as the financial markets generally, may be adversely impacted by trade disputes, including the imposition of tariffs, and other matters. For example, the United States has imposed trade barriers and restrictions on China. In addition, the Chinese government is engaged in a longstanding dispute with Taiwan, continually threatening an invasion. If the political climate between the United States and China does not improve or continues to deteriorate, if China were to attempt invading Taiwan, or if other geopolitical conflicts develop or worsen, economies, markets and individual securities may be adversely affected, and the value of the Fund’s assets may go down. A public health crisis and the ensuing policies enacted by governments and central banks may cause significant volatility and uncertainty in global financial markets, negatively impacting global growth prospects. As the COVID-19 global pandemic illustrated, such events may affect certain geographic regions, countries, sectors and industries more significantly than others. Advancements in technology may also adversely impact markets and the overall performance of the Fund. For instance, the economy may be significantly impacted by the advanced development and increased regulation of artificial intelligence. Additionally, cyber security breaches of both government and non-government entities could have negative impacts on infrastructure and the ability of such entities, including the Fund, to operate properly. These events, and any other future events, may adversely affect the prices and liquidity of the Fund’s portfolio investments and could result in disruptions in the trading markets.

Roundhill Inverse Russell 2000 WeeklyPay™ ETF | CYBERSECURITY RISK

Risk [Text Block]

CYBERSECURITY RISK. Failures or breaches of the electronic systems of the Fund, the Fund’s adviser, sub-adviser, distributor and other service providers, market makers, Authorized Participants or the issuers of securities in which the Fund invests have the ability to cause disruptions, negatively impact the Fund’s business operations and/or potentially result in financial losses to the Fund and its shareholders. While the Fund has established business continuity plans and risk management systems seeking to address system breaches or failures, there are inherent limitations in such plans and systems. Furthermore, the Fund cannot control the cybersecurity plans and systems of the Fund’s other service providers, market makers, Authorized Participants or issuers of securities in which the Fund invests.

Roundhill Inverse Russell 2000 WeeklyPay™ ETF | DEBT SECURITIES RISK  
Prospectus [Line Items]  
Risk [Text Block]

DEBT SECURITIES RISK. Investments in debt securities subject the holder to the credit risk of the issuer. Credit risk refers to the possibility that the issuer or other obligor of a security will not be able or willing to make payments of interest and principal when due. Generally, the value of debt securities will change inversely with changes in interest rates. To the extent that interest rates rise, certain underlying obligations may be paid off substantially slower than originally anticipated and the value of those securities may fall sharply. During periods of falling interest rates, the income received by the Fund may decline. If the principal on a debt security is prepaid before expected, the prepayments of principal may have to be reinvested in obligations paying interest at lower rates. Debt securities generally do not trade on a securities exchange making them generally less liquid and more difficult to value than common stock.

Roundhill Inverse Russell 2000 WeeklyPay™ ETF | DERIVATIVES RISK  
Prospectus [Line Items]  
Risk [Text Block]

DERIVATIVES RISK. The use of derivative instruments involves risks different from, or possibly greater than, the risks associated with investing directly in securities and other traditional investments. These risks include: (i) the risk that the counterparty to a derivative transaction may not fulfill its contractual obligations; (ii) risk of mispricing or improper valuation; and (iii) the risk that changes in the value of the derivative may not correlate perfectly with the underlying asset. Derivative prices are highly volatile and may fluctuate substantially during a short period of time. Such prices are influenced by numerous factors that affect the markets, including, but not limited to: changing supply and demand relationships; government programs and policies; national and international political and economic events, changes in interest rates, inflation and deflation and changes in supply and demand relationships. Trading derivative instruments involves risks different from, or possibly greater than, the risks associated with investing directly in securities. Derivative contracts ordinarily have leverage inherent in their terms. The use of leverage may cause the Fund to liquidate portfolio positions when it would not be advantageous to do so in order to satisfy its obligations or to meet regulatory or contractual requirements for derivatives. The use of derivatives can magnify potential for gain or loss and, therefore, amplify the effects of market volatility on share price.

Roundhill Inverse Russell 2000 WeeklyPay™ ETF | DISTRIBUTION TAX RISK  
Prospectus [Line Items]  
Risk [Text Block]

DISTRIBUTION TAX RISK. The Fund currently expects to make distributions on a weekly basis. Such frequent distributions may expose investors to increased tax liabilities. However, these distributions may exceed the Fund’s income and gains for the Fund’s taxable year. Distributions in excess of the Fund’s current and accumulated earnings and profits will be treated as a return of capital. A return of capital distribution generally will not be taxable but will reduce the shareholder’s cost basis and will result in a higher capital gain or lower capital loss when those Fund Shares on which the distribution was received are sold. Once a Fund shareholder’s cost basis is reduced to zero, further distributions will be treated as capital gain if the Fund shareholder holds Fund Shares as capital assets. Additionally, any capital returned through distributions will be distributed after payment of Fund fees and expenses. Because a portion of the Fund’s distributions may consist of return of capital, the Fund may not be an appropriate investment for investors who do not want their principal investment in the Fund to decrease over time or who do not wish to receive return of capital in a given period. In the event that a shareholder purchases Fund Shares shortly before a distribution by the Fund, the entire distribution may be taxable to the shareholder even though a portion of the distribution effectively represents a return of the purchase price.

Roundhill Inverse Russell 2000 WeeklyPay™ ETF | ETF RISK  
Prospectus [Line Items]  
Risk [Text Block]

ETF RISK. The Fund may invest in ETFs. The value of an ETF held by the Fund will fluctuate over time based on fluctuations in the values of the assets held by the ETF, which may be affected by changes in general economic conditions, expectations for future growth and profits, interest rates and the supply and demand for those assets. When the Fund invests in an ETF, it will bear a proportionate share of the ETF’s expenses. Brokerage, tax and other expenses may negatively impact the performance of the ETF and, in turn, the value of the Fund Shares. An ETF that tracks an index may not exactly match the performance of the index due to cash drag, differences between the portfolio of the ETF and the components of the index, expenses and other factors.

Roundhill Inverse Russell 2000 WeeklyPay™ ETF | INFLATION RISK  
Prospectus [Line Items]  
Risk [Text Block]

INFLATION RISK. Inflation risk is the risk that the value of assets or income from investments will be less in the future as inflation decreases the value of money. As inflation increases, the present value of the Fund’s assets and distributions may decline. This risk is more prevalent with respect to fixed income securities held by the Fund.

Roundhill Inverse Russell 2000 WeeklyPay™ ETF | Interest Rate Risk [Member]  
Prospectus [Line Items]  
Risk [Text Block]

INTEREST RATE RISK. Interest rate risk is the risk that the value of the debt securities in the Fund’s portfolio will decline because of rising market interest rates. Interest rate risk is generally lower for shorter term debt securities and higher for longer-term debt securities. Duration is a reasonably accurate measure of a debt security’s price sensitivity to changes in interest rates and a common measure of interest rate risk. Duration measures a debt security’s expected life on a present value basis, taking into account the debt security’s yield, interest payments and final maturity. In general, duration represents the expected percentage change in the value of a security for an immediate 1% change in interest rates. For example, the price of a debt security with a three-year duration would be expected to drop by approximately 3% in response to a 1% increase in interest rates. Therefore, prices of debt securities with shorter durations tend to be less sensitive to interest rate changes than debt securities with longer durations. As the value of a debt security changes over time, so will its duration.

Roundhill Inverse Russell 2000 WeeklyPay™ ETF | LEGISLATION AND LITIGATION RISK  
Prospectus [Line Items]  
Risk [Text Block]

LEGISLATION AND LITIGATION RISK. Legislation or litigation that affects the value of assets or securities held by the Fund may reduce the value of the Fund. From time to time, various legislative initiatives are proposed that may have a negative impact on certain assets or securities in which the Fund invests. In addition, litigation regarding any of the assets or securities owned by the Fund may negatively impact the value of the Fund Shares. Such legislation or litigation may cause the Fund to lose value or may result in higher portfolio turnover if the Adviser determines to sell such a holding.

Roundhill Inverse Russell 2000 WeeklyPay™ ETF | LEVERAGE RISK  
Prospectus [Line Items]  
Risk [Text Block]

LEVERAGE RISK. The Fund obtains investment exposure in excess of its net assets by utilizing leverage and may lose more money in market conditions that are adverse to its investment objectives than a fund that does not utilize leverage. An investment in the Fund is exposed to the risk that an increase in the weekly performance of shares of the Russell 2000 ETF will be magnified. This means that an investment in the Fund will be reduced by an amount equal to 1.2% for every 1% weekly increase in the market value of the Russell 2000 ETF shares, not including the costs of financing leverage and other operating expenses, which would further reduce its value. The Fund could theoretically lose an amount greater than its net assets in the event the market value of Russell 2000 ETF shares increase more than 83.33% over a calendar week. Leverage will also have the effect of magnifying any differences in the Fund’s correlation with Russell 2000 ETF shares.

Roundhill Inverse Russell 2000 WeeklyPay™ ETF | MONEY MARKET INSTRUMENTS RISK

Risk [Text Block]

MONEY MARKET INSTRUMENTS RISK. The value of money market instruments may be affected by changing interest rates and by changes in the credit ratings of the investments. If a significant amount of the Fund’s assets are invested in money market instruments, it will be more difficult for the Fund to achieve its investment objectives. An investment in a money market fund is not insured or guaranteed by the FDIC or any other government agency. It is possible to lose money by investing in a money market fund.

Roundhill Inverse Russell 2000 WeeklyPay™ ETF | OPERATIONAL RISK  
Prospectus [Line Items]  
Risk [Text Block]

OPERATIONAL RISK. The Fund is subject to risks arising from various operational factors, including, but not limited to, human error, processing and communication errors, errors of the Fund’s service providers, counterparties or other third-parties, failed or inadequate processes and technology or systems failures. The Fund relies on third-parties for a range of services, including custody. Any delay or failure relating to engaging or maintaining such service providers may affect the Fund’s ability to meet its investment objectives. Although the Fund and the Adviser seek to reduce these operational risks through controls and procedures, there is no way to completely protect against such risks.

Roundhill Inverse Russell 2000 WeeklyPay™ ETF | SPECIAL TAX RISK  
Prospectus [Line Items]  
Risk [Text Block]

SPECIAL TAX RISK. The Fund intends to qualify annually and to elect to be treated as a regulated investment company under the Internal Revenue Code of 1986, as amended (the “Code”). To qualify for the favorable U.S. federal income tax treatment generally accorded to regulated investment companies, the Fund must, among other things, (i) derive in each taxable year at least 90% of its gross income from dividends, interest, payments with respect to securities loans and gains from the sale or other disposition of stock, securities or foreign currencies or other income derived with respect to its business of investing in such stock, securities or currencies, or net income derived from interests in certain publicly traded partnerships; (ii) diversify its holdings so that, at the end of each quarter of the taxable year, (a) at least 50% of the market value of the Fund’s assets is represented by cash and cash items (including receivables), U.S. government securities, the securities of other regulated investment companies and other securities, with such other securities of any one issuer generally limited for the purposes of this calculation to an amount not greater than 5% of the value of the Fund’s total assets and not greater than 10% of the outstanding voting securities of such issuer, and (b) not more than 25% of the value of its total assets is invested in the securities (other than U.S. government securities or the securities of other regulated investment companies) of any one issuer, or two or more issuers which the Fund controls which are engaged in the same, similar or related trades or businesses, or the securities of one or more of certain publicly traded partnerships; and (iii) distribute at least 90% of its investment company taxable income (which includes, among other items, dividends, interest and net short-term capital gains in excess of net long-term capital losses) and at least 90% of its net tax-exempt interest income each taxable year. There are certain exceptions for failure to qualify if the failure is for reasonable cause or is de minimis, and certain corrective action is taken and certain tax payments are made by the Fund.

 

The authority with regard to swaps entered into by regulated investment companies is unclear both as to the qualification under the income test and the identification of the issuer under the diversification test. The Fund intends to take the position that because the swaps held by the Fund reference securities that the income on the swaps are “other income” from the Fund’s business of investing in stocks and securities. In addition, the Fund intends to manage its investments in the swaps so that neither the exposure to issuer of the referenced security nor the exposure to any one counterparty of the swaps will exceed 25% of the gross value of the Fund’s portfolio at the end of any quarter.

 

If the Fund were to fail to meet the qualifying income test or asset diversification test and fail to qualify as a RIC, it would be taxed in the same manner as an ordinary corporation, and distributions to its shareholders would not be deductible by the Fund in computing its taxable income, which would adversely affect the Fund’s performance.

Roundhill Inverse Russell 2000 WeeklyPay™ ETF | STRUCTURAL ETF RISKS  
Prospectus [Line Items]  
Risk [Text Block]

STRUCTURAL ETF RISKS. The Fund is an ETF. Accordingly, it is subject to certain risks associated with its unique structure.

 

Market Participants Risk. Only an Authorized Participant may engage in creation or redemption transactions directly with the Fund, and none of those Authorized Participants is obligated to engage in creation and/or redemption transactions. The Fund has a limited number of institutions that may act as Authorized Participants on an agency basis (i.e., on behalf of other market participants). To the extent that Authorized Participants exit the business or are unable to proceed with creation or redemption orders with respect to the Fund and no other Authorized Participant is able to step forward to create or redeem, Fund Shares may be more likely to trade at a premium or discount to NAV and possibly face trading halts or delisting. The Fund may also rely on a small number of third-party market makers to provide a market for the purchase and sale of Fund Shares but such market makers are under no obligation to do so. Decisions by Authorized Participants or market makers to reduce their role or step away from these activities in times of market stress could inhibit the effectiveness of the arbitrage process in maintaining the relationship between the underlying values of the Fund’s portfolio securities and the Fund’s market price. Any trading halt or other problem relating to the trading activity of these market makers or any issues disrupting the Authorized Participants’ ability to proceed with creation and/or redemption orders could result in a dramatic change in the spread between the Fund’s net asset value and the price at which Fund Shares are trading on the Exchange, which could result in a decrease in value of Fund Shares. This reduced effectiveness could result in Fund Shares trading at a premium or discount to net asset value and also in greater than normal intraday bid-ask spreads Fund Shares.

 

Cash Transactions Risk. The Fund currently expects to effect a significant portion of its creations and redemptions for cash, rather than in-kind securities. Paying redemption proceeds in cash rather than through in-kind delivery of portfolio securities may require the Fund to dispose of or sell portfolio securities or other assets at an inopportune time to obtain the cash needed to meet redemption orders. This may cause the Fund to sell a security and recognize a capital gain or loss that might not have been incurred if it had made a redemption in-kind. As a result, the Fund may pay out higher or lower annual capital gains distributions than ETFs that redeem in-kind. The use of cash creations and redemptions may also cause the Fund’s Shares to trade in the market at greater bid-ask spreads or greater premiums or discounts to the Fund’s net asset value (“NAV”). Furthermore, the Fund may not be able to execute cash transactions for creation and redemption purposes at the same price used to determine the Fund’s NAV. To the extent that the maximum additional charge for creation or redemption transactions is insufficient to cover the execution shortfall, the Fund’s performance could be negatively impacted.

 

Costs of Buying and Selling Fund Shares. Due to the costs of buying or selling Fund Shares, including brokerage commissions imposed by brokers and bid/ask spreads, frequent trading of Fund Shares may significantly reduce investment results and an investment in Fund Shares may not be advisable for investors who anticipate regularly making small investments.

 

Premium/Discount Risk. The trading prices of Fund Shares in the secondary market may differ from the Fund’s daily NAV per Fund Share and there may be times when the market price of the Fund Shares is more than the NAV per Fund Share (premium) or less than the NAV per Fund Share (discount). If a shareholder purchases Fund Shares at a time when the market price is at a premium to the NAV or sells Fund Shares at a time when the market price is at a discount to the NAV, the shareholder may pay more for, or receive less than, the underlying value of the Fund Shares, respectively. This risk is heightened in times of market volatility or periods of steep market declines.

 

Trading Risks. Although Fund Shares are listed for trading on the Exchange and may be traded on U.S. exchanges other than the Exchange, there can be no assurance that Fund Shares will trade with any volume, or at all, on any stock exchange. In stressed market conditions, the liquidity of Fund Shares may begin to mirror the liquidity of the Fund’s underlying portfolio holdings, which can be significantly less liquid than Fund Shares. Trading in Fund Shares on the Exchange may be halted due to market conditions or for reasons that, in the view of the Exchange, make trading in Fund Shares inadvisable. In addition, trading in Fund Shares on the Exchange is subject to trading halts caused by extraordinary market volatility pursuant to the Exchange’s “circuit breaker” rules. There can be no assurance that the requirements of the Exchange necessary to maintain the listing of the Fund will continue to be met or will remain unchanged.

Prospectus [Line Items]  
Risk [Text Block]

U.S. GOVERNMENT SECURITIES RISK. U.S. government securities are subject to interest rate risk but generally do not involve the credit risks associated with investments in other types of debt securities. As a result, the yields available from U.S. government securities are generally lower than the yields available from other debt securities. U.S. government securities are guaranteed only as to the timely payment of interest and the payment of principal when held to maturity.

Roundhill Inverse Russell 2000 WeeklyPay™ ETF | VALUATION RISK  
Prospectus [Line Items]  
Risk [Text Block]

VALUATION RISK. The Fund may hold securities or other assets that may be valued on the basis of factors other than market quotations. This may occur because the asset or security does not trade on a centralized exchange, or in times of market turmoil or reduced liquidity. There are multiple methods that can be used to value a portfolio holding when market quotations are not readily available. The value established for any portfolio holding at a point in time might differ from what would be produced using a different methodology or if it had been priced using market quotations. Portfolio holdings that are valued using techniques other than market quotations, including “fair valued” assets or securities, may be subject to greater fluctuation in their valuations from one day to the next than if market quotations were used. In addition, there is no assurance that the Fund could sell or close out a portfolio position for the value established for it at any time, and it is possible that the Fund would incur a loss because a portfolio position is sold or closed out at a discount to the valuation established by the Fund at that time. The Fund’s ability to value investments may be impacted by technological issues or errors by pricing services or other third-party service providers.

Roundhill Inverse Russell 2000 WeeklyPay™ ETF | SWAP AGREEMENTS RISK  
Prospectus [Line Items]  
Risk [Text Block]

SWAP AGREEMENTS RISK. The Fund will utilize swap agreements to derive its exposure to shares of the Russell 2000 ETF. Swap agreements may involve greater risks than direct investment in securities as they may be leveraged and are subject to credit risk, counterparty risk and valuation risk. A swap agreement could result in losses if the underlying reference or asset does not perform as anticipated. In addition, many swaps trade over-the-counter and may be considered illiquid. It may not be possible for the Fund to liquidate a swap position at an advantageous time or price, which may result in significant losses.

Roundhill Inverse Russell 2000 WeeklyPay™ ETF | NEW FUND RISK

Roundhill Inverse Russell 2000 WeeklyPay™ ETF | INVERSE CORRELATION RISK  
Prospectus [Line Items]

INVERSE CORRELATION RISK. The Fund seeks to provide a return equal to -1.2 times (-120%) the calendar week total return of shares of the Russell 2000 ETF. This means that the Fund will decrease in value when the Russell 2000 ETF increases in value, a result which is the opposite of traditional funds. The more that the Russell 2000 ETF increases in value over a given day, the more the Fund will decrease in value.

Roundhill Inverse Russell 2000 WeeklyPay™ ETF | RUSSELL 2000 ETF INVESTING RISKS  
Prospectus [Line Items]

RUSSELL 2000 ETF INVESTING RISKS. The Fund will have significant exposure to the Russell 2000 ETF through its investments in shares of the Russell 2000 ETF and swap agreements that utilize the Russell 2000 ETF as the reference asset. Accordingly, the Fund will subject to the risks of the Russell 2000 ETF, set forth below. In addition to these risks, the Russell 2000 ETF is also subject to the following risks to which the Fund is also subject, which are described within the section entitled “Principal Risks”: Market Risk, Asset Class Risk, Concentration Risk, Current Market Conditions Risk, Cybersecurity Risk, Operational Risk and Structural ETF Risk.

 

EQUITY SECURITIES RISK. Equity securities are subject to changes in value, and their values may be more volatile than those of other asset classes. Equity securities prices fluctuate for several reasons, including changes in investors’ perceptions of the financial condition of an issuer or the general condition of the relevant equity market, such as market volatility, or when political or economic events affecting an issuer occur. Common stock prices may be particularly sensitive to rising interest rates, as the cost of capital rises and borrowing costs increase. Common stocks generally subject their holders to more risks than preferred stocks and debt securities because common stockholders’ claims are subordinated to those of holders of preferred stocks and debt securities upon the bankruptcy of the issuer.

 

INDEX-RELATED RISK. The Russell 2000 ETF Index Provider may rely on various sources of information to assess the criteria of components of the Russell 2000 ETF Index, including information that may be based on assumptions and estimates. Neither the Russell 2000 ETF nor its investment adviser offer assurances that the Russell 2000 ETF Index Provider’s methodology or sources of information will provide an accurate assessment of included components or will result in the Russell 2000 ETF meeting its investment objective. Errors in index data, index computations or the construction of the Russell 2000 ETF Index in accordance with its methodology may occur, and the Russell 2000 ETF Index Provider may not identify or correct them promptly or at all, which may have an adverse impact on the Russell 2000 ETF and its shareholders. Unusual market conditions or other unforeseen circumstances (such as natural disasters, political unrest or war) may impact the Russell 2000 ETF Index Provider or a third-party data provider and could cause the Russell 2000 ETF Index Provider to postpone a scheduled rebalance. This could cause the Russell 2000 ETF Index to vary from its normal or expected composition.

 

INDIRECT INVESTMENT RISK. The Russell 2000 ETF is not affiliated with the Trust, the Fund, the Adviser, the Sub-Adviser or any affiliates thereof and is not involved with this offering in any way, and has no obligation to consider the Fund in taking any actions that might affect the value of the Fund. The Trust, the Fund, the Adviser, the Sub-Adviser or any affiliate are not responsible for the performance of the Russell 2000 ETF and make no representation as to the performance of the Russell 2000 ETF. Investing in the Fund is not equivalent to investing in the Russell 2000 ETF Fund. Shareholders will not have voting rights or rights to receive dividends or other distributions or any other rights with respect to the Russell 2000 ETF.

 

SMALL CAPITALIZATION COMPANIES RISK. Compared to mid- and large-capitalization companies, small-capitalization companies may be less stable and more susceptible to adverse developments. The securities of small-capitalization companies may be more volatile and less liquid than those of mid- and large-capitalization companies. As a result, the Russell 2000 ETF’s share price may be more volatile than that of a fund with a greater investment in large- or mid-capitalization stocks.

 

UNITED STATES RISK. Certain changes in the U.S. economy, such as when the U.S. economy weakens or when its financial markets decline, may have an adverse effect on the securities to which the Fund has exposure.

NON-DIVERSIFICATION RISK. As a “non-diversified” fund, the Fund may hold a smaller number of portfolio securities than many other funds. To the extent the Fund invests in a relatively small number of issuers, a decline in the market value of a particular security held by the Fund may affect its value more than if it invested in a larger number of issuers. The value of the Fund Shares may be more volatile than the values of shares of more diversified funds.

Risk [Text Block]

MARKET RISK. Market risk is the risk that a particular investment, or Fund Shares in general, may fall in value. Securities are subject to market fluctuations caused by real or perceived adverse economic, political, and regulatory factors or market developments, changes in interest rates, disruptions to trade, impositions of tariffs and perceived trends in securities prices. Fund Shares could decline in value or underperform other investments. In addition, local, regional or global events such as war, acts of terrorism, market manipulation, government defaults, government shutdowns, regulatory actions, political changes, diplomatic developments, the imposition of sanctions and other similar measures, spread of infectious diseases or other public health issues, recessions, natural disasters, or other events could have a significant negative impact on the Fund and its investments. Any of such circumstances could have a materially negative impact on the value of Fund Shares, the liquidity of an investment, and may result in increased market volatility. During any such events, Fund Shares may trade at increased premiums or discounts to their net asset value, the bid/ask spread on Fund Shares may widen and the returns on investment may fluctuate.

Roundhill Inverse Innovation-100 WeeklyPay™ ETF | LIQUIDITY RISK

Risk [Text Block]

LIQUIDITY RISK. The market for swap agreements that reference Innovation-100 ETF shares may be subject to periods of illiquidity. During such times it may be difficult or impossible to buy or sell a position at the desired price. Market disruptions or volatility can also make it difficult to find a counterparty willing to transact at a reasonable price and sufficient size. Illiquid markets may cause losses, which could be significant. The large size of the positions which the Fund may acquire increases the risk of illiquidity, may make its positions more difficult to liquidate, and may increase the losses incurred while trying to do so. Such large positions also may impact the price of swap agreements on Innovation-100 ETF shares.

Roundhill Inverse Innovation-100 WeeklyPay™ ETF | ACTIVE MANAGEMENT RISK

ACTIVE MANAGEMENT RISK. The Fund is actively-managed and its performance reflects investment decisions that the Adviser and/or Sub-Adviser makes for the Fund. Such judgments about the Fund’s investments may prove to be incorrect. If the investments selected and the strategies employed by the Fund fail to produce the intended results, the Fund could underperform as compared to other funds with similar investment objectives and/or strategies, or could have negative returns.

ACTIVE MARKET RISK. Although Fund Shares are listed for trading on the Exchange, there can be no assurance that an active trading market for Fund Shares will develop or be maintained. Fund Shares trade on the Exchange at market prices that may be below, at or above the Fund’s net asset value. Securities, including Fund Shares, are subject to market fluctuations and liquidity constraints that may be caused by such factors as economic, political, or regulatory developments, changes in interest rates, and/or perceived trends in securities prices. Fund Shares could decline in value or underperform other investments.

CONCENTRATION RISK. The Fund is susceptible to an increased risk of loss, including losses due to adverse events that affect the Fund’s investments more than the market as a whole, to the extent that the Fund’s investments are concentrated in investments that provide exposure to the Innovation-100 ETF and the industry or group of industries to which it is concentrated.

COUNTERPARTY RISK. Fund transactions involving a counterparty are subject to the risk that the counterparty will not fulfill its obligation to the Fund. Counterparty risk may arise because of the counterparty’s financial condition (i.e., financial difficulties, bankruptcy, or insolvency), market activities and developments, or other reasons, whether foreseen or not. A counterparty’s inability to fulfill its obligation may result in significant financial loss to the Fund. The Fund may be unable to recover its investment from the counterparty or may obtain a limited recovery, and/or recovery may be delayed.

Roundhill Inverse Innovation-100 WeeklyPay™ ETF | CURRENT MARKET CONDITIONS RISK  
Prospectus [Line Items]  
Risk [Text Block]

CURRENT MARKET CONDITIONS RISK. Current market conditions risk is the risk that a particular investment, or Fund Shares in general, may fall in value due to current market conditions. As a means to fight inflation, which remains at elevated levels, the Federal Reserve and certain foreign central banks have raised interest rates; however, the Federal Reserve has recently lowered interest rates and may continue to do so. U.S. regulators have proposed several changes to market and issuer regulations which would directly impact the Fund, and any regulatory changes could adversely impact the Fund’s ability to achieve its investment strategies or make certain investments. Recent and potential future bank failures could result in disruption to the broader banking industry or markets generally and reduce confidence in financial institutions and the economy as a whole, which may also heighten market volatility and reduce liquidity. Additionally, challenges in commercial real estate markets, including rising interest rates, declining valuations and increasing vacancies, could have a broader impact on financial markets. The ongoing adversarial political climate in the United States, as well as political and diplomatic events both domestic and abroad, have and may continue to have an adverse impact the U.S. regulatory landscape, markets and investor behavior, which could have a negative impact on the Fund’s investments and operations. The change in administration resulting from the 2024 United States national elections could result in significant impacts to international trade relations, tax and immigration policies, and other aspects of the national and international political and financial landscape, which could affect, among other things, inflation and the securities markets generally. Other unexpected political, regulatory and diplomatic events within the U.S. and abroad may affect investor and consumer confidence and may adversely impact financial markets and the broader economy. For example, ongoing armed conflicts between Russia and Ukraine in Europe and among Israel, Iran, Hamas and other militant groups in the Middle East, have caused and could continue to cause significant market disruptions and volatility within the markets in Russia, Europe, the Middle East and the United States. The hostilities and sanctions resulting from those hostilities have and could continue to have a significant impact on certain Fund investments as well as Fund performance and liquidity. The economies of the United States and its trading partners, as well as the financial markets generally, may be adversely impacted by trade disputes, including the imposition of tariffs, and other matters. For example, the United States has imposed trade barriers and restrictions on China. In addition, the Chinese government is engaged in a longstanding dispute with Taiwan, continually threatening an invasion. If the political climate between the United States and China does not improve or continues to deteriorate, if China were to attempt invading Taiwan, or if other geopolitical conflicts develop or worsen, economies, markets and individual securities may be adversely affected, and the value of the Fund’s assets may go down. A public health crisis and the ensuing policies enacted by governments and central banks may cause significant volatility and uncertainty in global financial markets, negatively impacting global growth prospects. As the COVID-19 global pandemic illustrated, such events may affect certain geographic regions, countries, sectors and industries more significantly than others. Advancements in technology may also adversely impact markets and the overall performance of the Fund. For instance, the economy may be significantly impacted by the advanced development and increased regulation of artificial intelligence. Additionally, cyber security breaches of both government and non-government entities could have negative impacts on infrastructure and the ability of such entities, including the Fund, to operate properly. These events, and any other future events, may adversely affect the prices and liquidity of the Fund’s portfolio investments and could result in disruptions in the trading markets.

Roundhill Inverse Innovation-100 WeeklyPay™ ETF | CYBERSECURITY RISK

Risk [Text Block]

CYBERSECURITY RISK. Failures or breaches of the electronic systems of the Fund, the Fund’s adviser, sub-adviser, distributor and other service providers, market makers, Authorized Participants or the issuers of securities in which the Fund invests have the ability to cause disruptions, negatively impact the Fund’s business operations and/or potentially result in financial losses to the Fund and its shareholders. While the Fund has established business continuity plans and risk management systems seeking to address system breaches or failures, there are inherent limitations in such plans and systems. Furthermore, the Fund cannot control the cybersecurity plans and systems of the Fund’s other service providers, market makers, Authorized Participants or issuers of securities in which the Fund invests.

Roundhill Inverse Innovation-100 WeeklyPay™ ETF | DEBT SECURITIES RISK  
Prospectus [Line Items]  
Risk [Text Block]

DEBT SECURITIES RISK. Investments in debt securities subject the holder to the credit risk of the issuer. Credit risk refers to the possibility that the issuer or other obligor of a security will not be able or willing to make payments of interest and principal when due. Generally, the value of debt securities will change inversely with changes in interest rates. To the extent that interest rates rise, certain underlying obligations may be paid off substantially slower than originally anticipated and the value of those securities may fall sharply. During periods of falling interest rates, the income received by the Fund may decline. If the principal on a debt security is prepaid before expected, the prepayments of principal may have to be reinvested in obligations paying interest at lower rates. Debt securities generally do not trade on a securities exchange making them generally less liquid and more difficult to value than common stock.

Roundhill Inverse Innovation-100 WeeklyPay™ ETF | DERIVATIVES RISK  
Prospectus [Line Items]  
Risk [Text Block]

DERIVATIVES RISK. The use of derivative instruments involves risks different from, or possibly greater than, the risks associated with investing directly in securities and other traditional investments. These risks include: (i) the risk that the counterparty to a derivative transaction may not fulfill its contractual obligations; (ii) risk of mispricing or improper valuation; and (iii) the risk that changes in the value of the derivative may not correlate perfectly with the underlying asset. Derivative prices are highly volatile and may fluctuate substantially during a short period of time. Such prices are influenced by numerous factors that affect the markets, including, but not limited to: changing supply and demand relationships; government programs and policies; national and international political and economic events, changes in interest rates, inflation and deflation and changes in supply and demand relationships. Trading derivative instruments involves risks different from, or possibly greater than, the risks associated with investing directly in securities. Derivative contracts ordinarily have leverage inherent in their terms. The use of leverage may cause the Fund to liquidate portfolio positions when it would not be advantageous to do so in order to satisfy its obligations or to meet regulatory or contractual requirements for derivatives. The use of derivatives can magnify potential for gain or loss and, therefore, amplify the effects of market volatility on share price.

Roundhill Inverse Innovation-100 WeeklyPay™ ETF | DISTRIBUTION TAX RISK  
Prospectus [Line Items]  
Risk [Text Block]

DISTRIBUTION TAX RISK. The Fund currently expects to make distributions on a weekly basis. Such frequent distributions may expose investors to increased tax liabilities. However, these distributions may exceed the Fund’s income and gains for the Fund’s taxable year. Distributions in excess of the Fund’s current and accumulated earnings and profits will be treated as a return of capital. A return of capital distribution generally will not be taxable but will reduce the shareholder’s cost basis and will result in a higher capital gain or lower capital loss when those Fund Shares on which the distribution was received are sold. Once a Fund shareholder’s cost basis is reduced to zero, further distributions will be treated as capital gain if the Fund shareholder holds Fund Shares as capital assets. Additionally, any capital returned through distributions will be distributed after payment of Fund fees and expenses. Because a portion of the Fund’s distributions may consist of return of capital, the Fund may not be an appropriate investment for investors who do not want their principal investment in the Fund to decrease over time or who do not wish to receive return of capital in a given period. In the event that a shareholder purchases Fund Shares shortly before a distribution by the Fund, the entire distribution may be taxable to the shareholder even though a portion of the distribution effectively represents a return of the purchase price.

Roundhill Inverse Innovation-100 WeeklyPay™ ETF | ETF RISK  
Prospectus [Line Items]  
Risk [Text Block]

ETF RISK. The Fund may invest in ETFs. The value of an ETF held by the Fund will fluctuate over time based on fluctuations in the values of the assets held by the ETF, which may be affected by changes in general economic conditions, expectations for future growth and profits, interest rates and the supply and demand for those assets. When the Fund invests in an ETF, it will bear a proportionate share of the ETF’s expenses. Brokerage, tax and other expenses may negatively impact the performance of the ETF and, in turn, the value of the Fund Shares. An ETF that tracks an index may not exactly match the performance of the index due to cash drag, differences between the portfolio of the ETF and the components of the index, expenses and other factors.

Roundhill Inverse Innovation-100 WeeklyPay™ ETF | INFLATION RISK  
Prospectus [Line Items]  
Risk [Text Block]

INFLATION RISK. Inflation risk is the risk that the value of assets or income from investments will be less in the future as inflation decreases the value of money. As inflation increases, the present value of the Fund’s assets and distributions may decline. This risk is more prevalent with respect to fixed income securities held by the Fund.

Roundhill Inverse Innovation-100 WeeklyPay™ ETF | Interest Rate Risk [Member]  
Prospectus [Line Items]  
Risk [Text Block]

INTEREST RATE RISK. Interest rate risk is the risk that the value of the debt securities in the Fund’s portfolio will decline because of rising market interest rates. Interest rate risk is generally lower for shorter term debt securities and higher for longer-term debt securities. Duration is a reasonably accurate measure of a debt security’s price sensitivity to changes in interest rates and a common measure of interest rate risk. Duration measures a debt security’s expected life on a present value basis, taking into account the debt security’s yield, interest payments and final maturity. In general, duration represents the expected percentage change in the value of a security for an immediate 1% change in interest rates. For example, the price of a debt security with a three-year duration would be expected to drop by approximately 3% in response to a 1% increase in interest rates. Therefore, prices of debt securities with shorter durations tend to be less sensitive to interest rate changes than debt securities with longer durations. As the value of a debt security changes over time, so will its duration.

Roundhill Inverse Innovation-100 WeeklyPay™ ETF | LEGISLATION AND LITIGATION RISK  
Prospectus [Line Items]  
Risk [Text Block]

LEGISLATION AND LITIGATION RISK. Legislation or litigation that affects the value of assets or securities held by the Fund may reduce the value of the Fund. From time to time, various legislative initiatives are proposed that may have a negative impact on certain assets or securities in which the Fund invests. In addition, litigation regarding any of the assets or securities owned by the Fund may negatively impact the value of the Fund Shares. Such legislation or litigation may cause the Fund to lose value or may result in higher portfolio turnover if the Adviser determines to sell such a holding.

Roundhill Inverse Innovation-100 WeeklyPay™ ETF | LEVERAGE RISK  
Prospectus [Line Items]  
Risk [Text Block]

LEVERAGE RISK. The Fund obtains investment exposure in excess of its net assets by utilizing leverage and may lose more money in market conditions that are adverse to its investment objectives than a fund that does not utilize leverage. An investment in the Fund is exposed to the risk that an increase in the weekly performance of shares of the Innovation-100 ETF will be magnified. This means that an investment in the Fund will be reduced by an amount equal to 1.2% for every 1% weekly increase in the market value of the Innovation-100 ETF shares, not including the costs of financing leverage and other operating expenses, which would further reduce its value. The Fund could theoretically lose an amount greater than its net assets in the event the market value of Innovation-100 ETF shares increase more than 83.33% over a calendar week. Leverage will also have the effect of magnifying any differences in the Fund’s correlation with Innovation-100 ETF shares.

Roundhill Inverse Innovation-100 WeeklyPay™ ETF | MONEY MARKET INSTRUMENTS RISK  
Prospectus [Line Items]  
Risk [Text Block]

MONEY MARKET INSTRUMENTS RISK. The value of money market instruments may be affected by changing interest rates and by changes in the credit ratings of the investments. If a significant amount of the Fund’s assets are invested in money market instruments, it will be more difficult for the Fund to achieve its investment objectives. An investment in a money market fund is not insured or guaranteed by the FDIC or any other government agency. It is possible to lose money by investing in a money market fund.

Roundhill Inverse Innovation-100 WeeklyPay™ ETF | OPERATIONAL RISK  
Prospectus [Line Items]  
Risk [Text Block]

OPERATIONAL RISK. The Fund is subject to risks arising from various operational factors, including, but not limited to, human error, processing and communication errors, errors of the Fund’s service providers, counterparties or other third-parties, failed or inadequate processes and technology or systems failures. The Fund relies on third-parties for a range of services, including custody. Any delay or failure relating to engaging or maintaining such service providers may affect the Fund’s ability to meet its investment objectives. Although the Fund and the Adviser seek to reduce these operational risks through controls and procedures, there is no way to completely protect against such risks.

Roundhill Inverse Innovation-100 WeeklyPay™ ETF | SPECIAL TAX RISK  
Prospectus [Line Items]  
Risk [Text Block]

SPECIAL TAX RISK. The Fund intends to qualify annually and to elect to be treated as a regulated investment company under the Internal Revenue Code of 1986, as amended (the “Code”). To qualify for the favorable U.S. federal income tax treatment generally accorded to regulated investment companies, the Fund must, among other things, (i) derive in each taxable year at least 90% of its gross income from dividends, interest, payments with respect to securities loans and gains from the sale or other disposition of stock, securities or foreign currencies or other income derived with respect to its business of investing in such stock, securities or currencies, or net income derived from interests in certain publicly traded partnerships; (ii) diversify its holdings so that, at the end of each quarter of the taxable year, (a) at least 50% of the market value of the Fund’s assets is represented by cash and cash items (including receivables), U.S. government securities, the securities of other regulated investment companies and other securities, with such other securities of any one issuer generally limited for the purposes of this calculation to an amount not greater than 5% of the value of the Fund’s total assets and not greater than 10% of the outstanding voting securities of such issuer, and (b) not more than 25% of the value of its total assets is invested in the securities (other than U.S. government securities or the securities of other regulated investment companies) of any one issuer, or two or more issuers which the Fund controls which are engaged in the same, similar or related trades or businesses, or the securities of one or more of certain publicly traded partnerships; and (iii) distribute at least 90% of its investment company taxable income (which includes, among other items, dividends, interest and net short-term capital gains in excess of net long-term capital losses) and at least 90% of its net tax-exempt interest income each taxable year. There are certain exceptions for failure to qualify if the failure is for reasonable cause or is de minimis, and certain corrective action is taken and certain tax payments are made by the Fund.

 

The authority with regard to swaps entered into by regulated investment companies is unclear both as to the qualification under the income test and the identification of the issuer under the diversification test. The Fund intends to take the position that because the swaps held by the Fund reference securities that the income on the swaps are “other income” from the Fund’s business of investing in stocks and securities. In addition, the Fund intends to manage its investments in the swaps so that neither the exposure to issuer of the referenced security nor the exposure to any one counterparty of the swaps will exceed 25% of the gross value of the Fund’s portfolio at the end of any quarter.

 

If the Fund were to fail to meet the qualifying income test or asset diversification test and fail to qualify as a RIC, it would be taxed in the same manner as an ordinary corporation, and distributions to its shareholders would not be deductible by the Fund in computing its taxable income, which would adversely affect the Fund’s performance.

Roundhill Inverse Innovation-100 WeeklyPay™ ETF | STRUCTURAL ETF RISKS  
Prospectus [Line Items]  
Risk [Text Block]

STRUCTURAL ETF RISKS. The Fund is an ETF. Accordingly, it is subject to certain risks associated with its unique structure.

 

Market Participants Risk. Only an Authorized Participant may engage in creation or redemption transactions directly with the Fund, and none of those Authorized Participants is obligated to engage in creation and/or redemption transactions. The Fund has a limited number of institutions that may act as Authorized Participants on an agency basis (i.e., on behalf of other market participants). To the extent that Authorized Participants exit the business or are unable to proceed with creation or redemption orders with respect to the Fund and no other Authorized Participant is able to step forward to create or redeem, Fund Shares may be more likely to trade at a premium or discount to NAV and possibly face trading halts or delisting. The Fund may also rely on a small number of third-party market makers to provide a market for the purchase and sale of Fund Shares but such market makers are under no obligation to do so. Decisions by Authorized Participants or market makers to reduce their role or step away from these activities in times of market stress could inhibit the effectiveness of the arbitrage process in maintaining the relationship between the underlying values of the Fund’s portfolio securities and the Fund’s market price. Any trading halt or other problem relating to the trading activity of these market makers or any issues disrupting the Authorized Participants’ ability to proceed with creation and/or redemption orders could result in a dramatic change in the spread between the Fund’s net asset value and the price at which Fund Shares are trading on the Exchange, which could result in a decrease in value of Fund Shares. This reduced effectiveness could result in Fund Shares trading at a premium or discount to net asset value and also in greater than normal intraday bid-ask spreads Fund Shares.

 

Cash Transactions Risk. The Fund currently expects to effect a significant portion of its creations and redemptions for cash, rather than in-kind securities. Paying redemption proceeds in cash rather than through in-kind delivery of portfolio securities may require the Fund to dispose of or sell portfolio securities or other assets at an inopportune time to obtain the cash needed to meet redemption orders. This may cause the Fund to sell a security and recognize a capital gain or loss that might not have been incurred if it had made a redemption in-kind. As a result, the Fund may pay out higher or lower annual capital gains distributions than ETFs that redeem in-kind. The use of cash creations and redemptions may also cause the Fund’s Shares to trade in the market at greater bid-ask spreads or greater premiums or discounts to the Fund’s net asset value (“NAV”). Furthermore, the Fund may not be able to execute cash transactions for creation and redemption purposes at the same price used to determine the Fund’s NAV. To the extent that the maximum additional charge for creation or redemption transactions is insufficient to cover the execution shortfall, the Fund’s performance could be negatively impacted.

 

Costs of Buying and Selling Fund Shares. Due to the costs of buying or selling Fund Shares, including brokerage commissions imposed by brokers and bid/ask spreads, frequent trading of Fund Shares may significantly reduce investment results and an investment in Fund Shares may not be advisable for investors who anticipate regularly making small investments.

 

Premium/Discount Risk. The trading prices of Fund Shares in the secondary market may differ from the Fund’s daily NAV per Fund Share and there may be times when the market price of the Fund Shares is more than the NAV per Fund Share (premium) or less than the NAV per Fund Share (discount). If a shareholder purchases Fund Shares at a time when the market price is at a premium to the NAV or sells Fund Shares at a time when the market price is at a discount to the NAV, the shareholder may pay more for, or receive less than, the underlying value of the Fund Shares, respectively. This risk is heightened in times of market volatility or periods of steep market declines.

 

Trading Risks. Although Fund Shares are listed for trading on the Exchange and may be traded on U.S. exchanges other than the Exchange, there can be no assurance that Fund Shares will trade with any volume, or at all, on any stock exchange. In stressed market conditions, the liquidity of Fund Shares may begin to mirror the liquidity of the Fund’s underlying portfolio holdings, which can be significantly less liquid than Fund Shares. Trading in Fund Shares on the Exchange may be halted due to market conditions or for reasons that, in the view of the Exchange, make trading in Fund Shares inadvisable. In addition, trading in Fund Shares on the Exchange is subject to trading halts caused by extraordinary market volatility pursuant to the Exchange’s “circuit breaker” rules. There can be no assurance that the requirements of the Exchange necessary to maintain the listing of the Fund will continue to be met or will remain unchanged.

Roundhill Inverse Innovation-100 WeeklyPay™ ETF | U.S. GOVERNMENT SECURITIES RISK  
Prospectus [Line Items]  
Risk [Text Block]

U.S. GOVERNMENT SECURITIES RISK. U.S. government securities are subject to interest rate risk but generally do not involve the credit risks associated with investments in other types of debt securities. As a result, the yields available from U.S. government securities are generally lower than the yields available from other debt securities. U.S. government securities are guaranteed only as to the timely payment of interest and the payment of principal when held to maturity.

Roundhill Inverse Innovation-100 WeeklyPay™ ETF | VALUATION RISK  
Prospectus [Line Items]  
Risk [Text Block]

VALUATION RISK. The Fund may hold securities or other assets that may be valued on the basis of factors other than market quotations. This may occur because the asset or security does not trade on a centralized exchange, or in times of market turmoil or reduced liquidity. There are multiple methods that can be used to value a portfolio holding when market quotations are not readily available. The value established for any portfolio holding at a point in time might differ from what would be produced using a different methodology or if it had been priced using market quotations. Portfolio holdings that are valued using techniques other than market quotations, including “fair valued” assets or securities, may be subject to greater fluctuation in their valuations from one day to the next than if market quotations were used. In addition, there is no assurance that the Fund could sell or close out a portfolio position for the value established for it at any time, and it is possible that the Fund would incur a loss because a portfolio position is sold or closed out at a discount to the valuation established by the Fund at that time. The Fund’s ability to value investments may be impacted by technological issues or errors by pricing services or other third-party service providers.

Roundhill Inverse Innovation-100 WeeklyPay™ ETF | SWAP AGREEMENTS RISK  
Prospectus [Line Items]  
Risk [Text Block]

SWAP AGREEMENTS RISK. The Fund will utilize swap agreements to derive its exposure to shares of the Innovation-100 ETF. Swap agreements may involve greater risks than direct investment in securities as they may be leveraged and are subject to credit risk, counterparty risk and valuation risk. A swap agreement could result in losses if the underlying reference or asset does not perform as anticipated. In addition, many swaps trade over-the-counter and may be considered illiquid. It may not be possible for the Fund to liquidate a swap position at an advantageous time or price, which may result in significant losses.

Roundhill Inverse Innovation-100 WeeklyPay™ ETF | NEW FUND RISK

NEW FUND RISK. The Fund is a recently organized investment company with a limited operating history. As a result, prospective investors have a limited track record or history on which to base their investment decision.

Roundhill Inverse Innovation-100 WeeklyPay™ ETF | INVERSE CORRELATION RISK  
Prospectus [Line Items]  
Risk [Text Block]

INVERSE CORRELATION RISK. The Fund seeks to provide a return equal to -1.2 times (-120%) the calendar week total return of shares of the Innovation-100 ETF. This means that the Fund will decrease in value when the Innovation-100 ETF increases in value, a result which is the opposite of traditional funds. The more that the Innovation-100 ETF increases in value over a given day, the more the Fund will decrease in value.

Roundhill Inverse Innovation-100 WeeklyPay™ ETF | INNOVATION-100 ETF INVESTING RISKS  
Prospectus [Line Items]  
Risk [Text Block]

INNOVATION-100 ETF INVESTING RISKS. The Fund will have significant exposure to the Innovation-100 ETF through its investments in shares of the Innovation-100 ETF and swap agreements that utilize the Innovation-100 ETF as the reference asset. Accordingly, the Fund will subject to the risks of the Innovation-100 ETF, set forth below. In addition to these risks, the Innovation-100 ETF is also subject to the following risks to which the Fund is also subject, which are described within the section entitled “Principal Risks”: Market Risk, Asset Class Risk, Concentration Risk, Current Market Conditions Risk, Cybersecurity Risk, Operational Risk and Structural ETF Risk.

 

EQUITY SECURITIES RISK. Equity securities are subject to changes in value, and their values may be more volatile than those of other asset classes. Equity securities prices fluctuate for several reasons, including changes in investors’ perceptions of the financial condition of an issuer or the general condition of the relevant equity market, such as market volatility, or when political or economic events affecting an issuer occur. Common stock prices may be particularly sensitive to rising interest rates, as the cost of capital rises and borrowing costs increase. Common stocks generally subject their holders to more risks than preferred stocks and debt securities because common stockholders’ claims are subordinated to those of holders of preferred stocks and debt securities upon the bankruptcy of the issuer.

 

INDEX-RELATED RISK. The Innovation-100 ETF Index Provider may rely on various sources of information to assess the criteria of components of the Innovation-100 ETF Index, including information that may be based on assumptions and estimates. Neither the Innovation-100 ETF nor its investment adviser offer assurances that the Innovation-100 ETF Index Provider’s methodology or sources of information will provide an accurate assessment of included components or will result in the Innovation-100 ETF meeting its investment objective. Errors in index data, index computations or the construction of the Innovation-100 ETF Index in accordance with its methodology may occur, and the Innovation-100 ETF Index Provider may not identify or correct them promptly or at all, which may have an adverse impact on the Innovation-100 ETF and its shareholders. Unusual market conditions or other unforeseen circumstances (such as natural disasters, political unrest or war) may impact the Innovation-100 ETF Index Provider or a third-party data provider and could cause the Innovation-100 ETF Index Provider to postpone a scheduled rebalance. This could cause the Innovation-100 ETF Index to vary from its normal or expected composition.

 

INDIRECT INVESTMENT RISK. The Innovation-100 ETF is not affiliated with the Trust, the Fund, the Adviser, the Sub-Adviser or any affiliates thereof and is not involved with this offering in any way, and has no obligation to consider the Fund in taking any actions that might affect the value of the Fund. The Trust, the Fund, the Adviser, the Sub-Adviser or any affiliate are not responsible for the performance of the Innovation-100 ETF and make no representation as to the performance of the Innovation-100 ETF. Investing in the Fund is not equivalent to investing in the Innovation-100 ETF Fund. Shareholders will not have voting rights or rights to receive dividends or other distributions or any other rights with respect to the Innovation-100 ETF.

 

INFORMATION TECHNOLOGY COMPANIES RISK. Information technology companies face intense competition, both domestically and internationally, which may have an adverse effect on profit margins. Like other technology companies, information technology companies may have limited product lines, markets, financial resources or personnel. The products of information technology companies may face obsolescence due to rapid technological developments, frequent new product introduction, unpredictable changes in growth rates and competition for the services of qualified personnel. Companies in the information technology sector are heavily dependent on patent and intellectual property rights. The loss or impairment of these rights may adversely affect the profitability of these companies. Information technology companies are facing increased government and regulatory scrutiny and may be subject to adverse government or regulatory action.

 

LARGE CAPITALIZATION COMPANIES RISK. Large capitalization companies may be less able than smaller capitalization companies to adapt to changing market conditions. Large capitalization companies may be more mature and subject to more limited growth potential compared with smaller capitalization companies. During different market cycles, the performance of large capitalization companies has trailed the overall performance of the broader securities markets.

 

UNITED STATES RISK. Certain changes in the U.S. economy, such as when the U.S. economy weakens or when its financial markets decline, may have an adverse effect on the securities to which the Fund has exposure.

Risk [Text Block]

NON-DIVERSIFICATION RISK. As a “non-diversified” fund, the Fund may hold a smaller number of portfolio securities than many other funds. To the extent the Fund invests in a relatively small number of issuers, a decline in the market value of a particular security held by the Fund may affect its value more than if it invested in a larger number of issuers. The value of the Fund Shares may be more volatile than the values of shares of more diversified funds.

Roundhill Inverse S&P 500® WeeklyPay™ ETF | MARKET RISK  
Prospectus [Line Items]  
Risk [Text Block]

MARKET RISK. Market risk is the risk that a particular investment, or Fund Shares in general, may fall in value. Securities are subject to market fluctuations caused by real or perceived adverse economic, political, and regulatory factors or market developments, changes in interest rates, disruptions to trade, impositions of tariffs and perceived trends in securities prices. Fund Shares could decline in value or underperform other investments. In addition, local, regional or global events such as war, acts of terrorism, market manipulation, government defaults, government shutdowns, regulatory actions, political changes, diplomatic developments, the imposition of sanctions and other similar measures, spread of infectious diseases or other public health issues, recessions, natural disasters, or other events could have a significant negative impact on the Fund and its investments. Any of such circumstances could have a materially negative impact on the value of Fund Shares, the liquidity of an investment, and may result in increased market volatility. During any such events, Fund Shares may trade at increased premiums or discounts to their net asset value, the bid/ask spread on Fund Shares may widen and the returns on investment may fluctuate.

Roundhill Inverse S&P 500® WeeklyPay™ ETF | LIQUIDITY RISK

Risk [Text Block]

LIQUIDITY RISK. The market for swap agreements that reference S&P 500® ETF shares may be subject to periods of illiquidity. During such times it may be difficult or impossible to buy or sell a position at the desired price. Market disruptions or volatility can also make it difficult to find a counterparty willing to transact at a reasonable price and sufficient size. Illiquid markets may cause losses, which could be significant. The large size of the positions which the Fund may acquire increases the risk of illiquidity, may make its positions more difficult to liquidate, and may increase the losses incurred while trying to do so. Such large positions also may impact the price of swap agreements on S&P S&P 500® ETF shares.

ACTIVE MANAGEMENT RISK. The Fund is actively-managed and its performance reflects investment decisions that the Adviser and/or Sub-Adviser makes for the Fund. Such judgments about the Fund’s investments may prove to be incorrect. If the investments selected and the strategies employed by the Fund fail to produce the intended results, the Fund could underperform as compared to other funds with similar investment objectives and/or strategies, or could have negative returns.

ACTIVE MARKET RISK. Although Fund Shares are listed for trading on the Exchange, there can be no assurance that an active trading market for Fund Shares will develop or be maintained. Fund Shares trade on the Exchange at market prices that may be below, at or above the Fund’s net asset value. Securities, including Fund Shares, are subject to market fluctuations and liquidity constraints that may be caused by such factors as economic, political, or regulatory developments, changes in interest rates, and/or perceived trends in securities prices. Fund Shares could decline in value or underperform other investments.

CONCENTRATION RISK. The Fund is susceptible to an increased risk of loss, including losses due to adverse events that affect the Fund’s investments more than the market as a whole, to the extent that the Fund’s investments are concentrated in investments that provide exposure to the S&P 500® ETF and the industry or group of industries to which it is concentrated.

Risk [Text Block]

COUNTERPARTY RISK. Fund transactions involving a counterparty are subject to the risk that the counterparty will not fulfill its obligation to the Fund. Counterparty risk may arise because of the counterparty’s financial condition (i.e., financial difficulties, bankruptcy, or insolvency), market activities and developments, or other reasons, whether foreseen or not. A counterparty’s inability to fulfill its obligation may result in significant financial loss to the Fund. The Fund may be unable to recover its investment from the counterparty or may obtain a limited recovery, and/or recovery may be delayed.

Roundhill Inverse S&P 500® WeeklyPay™ ETF | CURRENT MARKET CONDITIONS RISK  
Prospectus [Line Items]  
Risk [Text Block]

CURRENT MARKET CONDITIONS RISK. Current market conditions risk is the risk that a particular investment, or Fund Shares in general, may fall in value due to current market conditions. As a means to fight inflation, which remains at elevated levels, the Federal Reserve and certain foreign central banks have raised interest rates; however, the Federal Reserve has recently lowered interest rates and may continue to do so. U.S. regulators have proposed several changes to market and issuer regulations which would directly impact the Fund, and any regulatory changes could adversely impact the Fund’s ability to achieve its investment strategies or make certain investments. Recent and potential future bank failures could result in disruption to the broader banking industry or markets generally and reduce confidence in financial institutions and the economy as a whole, which may also heighten market volatility and reduce liquidity. Additionally, challenges in commercial real estate markets, including rising interest rates, declining valuations and increasing vacancies, could have a broader impact on financial markets. The ongoing adversarial political climate in the United States, as well as political and diplomatic events both domestic and abroad, have and may continue to have an adverse impact the U.S. regulatory landscape, markets and investor behavior, which could have a negative impact on the Fund’s investments and operations. The change in administration resulting from the 2024 United States national elections could result in significant impacts to international trade relations, tax and immigration policies, and other aspects of the national and international political and financial landscape, which could affect, among other things, inflation and the securities markets generally. Other unexpected political, regulatory and diplomatic events within the U.S. and abroad may affect investor and consumer confidence and may adversely impact financial markets and the broader economy. For example, ongoing armed conflicts between Russia and Ukraine in Europe and among Israel, Iran, Hamas and other militant groups in the Middle East, have caused and could continue to cause significant market disruptions and volatility within the markets in Russia, Europe, the Middle East and the United States. The hostilities and sanctions resulting from those hostilities have and could continue to have a significant impact on certain Fund investments as well as Fund performance and liquidity. The economies of the United States and its trading partners, as well as the financial markets generally, may be adversely impacted by trade disputes, including the imposition of tariffs, and other matters. For example, the United States has imposed trade barriers and restrictions on China. In addition, the Chinese government is engaged in a longstanding dispute with Taiwan, continually threatening an invasion. If the political climate between the United States and China does not improve or continues to deteriorate, if China were to attempt invading Taiwan, or if other geopolitical conflicts develop or worsen, economies, markets and individual securities may be adversely affected, and the value of the Fund’s assets may go down. A public health crisis and the ensuing policies enacted by governments and central banks may cause significant volatility and uncertainty in global financial markets, negatively impacting global growth prospects. As the COVID-19 global pandemic illustrated, such events may affect certain geographic regions, countries, sectors and industries more significantly than others. Advancements in technology may also adversely impact markets and the overall performance of the Fund. For instance, the economy may be significantly impacted by the advanced development and increased regulation of artificial intelligence. Additionally, cyber security breaches of both government and non-government entities could have negative impacts on infrastructure and the ability of such entities, including the Fund, to operate properly. These events, and any other future events, may adversely affect the prices and liquidity of the Fund’s portfolio investments and could result in disruptions in the trading markets.

Roundhill Inverse S&P 500® WeeklyPay™ ETF | CYBERSECURITY RISK

Risk [Text Block]

CYBERSECURITY RISK. Failures or breaches of the electronic systems of the Fund, the Fund’s adviser, sub-adviser, distributor and other service providers, market makers, Authorized Participants or the issuers of securities in which the Fund invests have the ability to cause disruptions, negatively impact the Fund’s business operations and/or potentially result in financial losses to the Fund and its shareholders. While the Fund has established business continuity plans and risk management systems seeking to address system breaches or failures, there are inherent limitations in such plans and systems. Furthermore, the Fund cannot control the cybersecurity plans and systems of the Fund’s other service providers, market makers, Authorized Participants or issuers of securities in which the Fund invests.

Roundhill Inverse S&P 500® WeeklyPay™ ETF | DEBT SECURITIES RISK  
Prospectus [Line Items]  
Risk [Text Block]

DEBT SECURITIES RISK. Investments in debt securities subject the holder to the credit risk of the issuer. Credit risk refers to the possibility that the issuer or other obligor of a security will not be able or willing to make payments of interest and principal when due. Generally, the value of debt securities will change inversely with changes in interest rates. To the extent that interest rates rise, certain underlying obligations may be paid off substantially slower than originally anticipated and the value of those securities may fall sharply. During periods of falling interest rates, the income received by the Fund may decline. If the principal on a debt security is prepaid before expected, the prepayments of principal may have to be reinvested in obligations paying interest at lower rates. Debt securities generally do not trade on a securities exchange making them generally less liquid and more difficult to value than common stock.

Roundhill Inverse S&P 500® WeeklyPay™ ETF | DERIVATIVES RISK  
Prospectus [Line Items]  
Risk [Text Block]

DERIVATIVES RISK. The use of derivative instruments involves risks different from, or possibly greater than, the risks associated with investing directly in securities and other traditional investments. These risks include: (i) the risk that the counterparty to a derivative transaction may not fulfill its contractual obligations; (ii) risk of mispricing or improper valuation; and (iii) the risk that changes in the value of the derivative may not correlate perfectly with the underlying asset. Derivative prices are highly volatile and may fluctuate substantially during a short period of time. Such prices are influenced by numerous factors that affect the markets, including, but not limited to: changing supply and demand relationships; government programs and policies; national and international political and economic events, changes in interest rates, inflation and deflation and changes in supply and demand relationships. Trading derivative instruments involves risks different from, or possibly greater than, the risks associated with investing directly in securities. Derivative contracts ordinarily have leverage inherent in their terms. The use of leverage may cause the Fund to liquidate portfolio positions when it would not be advantageous to do so in order to satisfy its obligations or to meet regulatory or contractual requirements for derivatives. The use of derivatives can magnify potential for gain or loss and, therefore, amplify the effects of market volatility on share price.

Roundhill Inverse S&P 500® WeeklyPay™ ETF | DISTRIBUTION TAX RISK  
Prospectus [Line Items]  
Risk [Text Block]

DISTRIBUTION TAX RISK. The Fund currently expects to make distributions on a weekly basis. Such frequent distributions may expose investors to increased tax liabilities. However, these distributions may exceed the Fund’s income and gains for the Fund’s taxable year. Distributions in excess of the Fund’s current and accumulated earnings and profits will be treated as a return of capital. A return of capital distribution generally will not be taxable but will reduce the shareholder’s cost basis and will result in a higher capital gain or lower capital loss when those Fund Shares on which the distribution was received are sold. Once a Fund shareholder’s cost basis is reduced to zero, further distributions will be treated as capital gain if the Fund shareholder holds Fund Shares as capital assets. Additionally, any capital returned through distributions will be distributed after payment of Fund fees and expenses. Because a portion of the Fund’s distributions may consist of return of capital, the Fund may not be an appropriate investment for investors who do not want their principal investment in the Fund to decrease over time or who do not wish to receive return of capital in a given period. In the event that a shareholder purchases Fund Shares shortly before a distribution by the Fund, the entire distribution may be taxable to the shareholder even though a portion of the distribution effectively represents a return of the purchase price.

Roundhill Inverse S&P 500® WeeklyPay™ ETF | ETF RISK  
Prospectus [Line Items]  
Risk [Text Block]

ETF RISK. The Fund may invest in ETFs. The value of an ETF held by the Fund will fluctuate over time based on fluctuations in the values of the assets held by the ETF, which may be affected by changes in general economic conditions, expectations for future growth and profits, interest rates and the supply and demand for those assets. When the Fund invests in an ETF, it will bear a proportionate share of the ETF’s expenses. Brokerage, tax and other expenses may negatively impact the performance of the ETF and, in turn, the value of the Fund Shares. An ETF that tracks an index may not exactly match the performance of the index due to cash drag, differences between the portfolio of the ETF and the components of the index, expenses and other factors.

Roundhill Inverse S&P 500® WeeklyPay™ ETF | INFLATION RISK  
Prospectus [Line Items]  
Risk [Text Block]

INFLATION RISK. Inflation risk is the risk that the value of assets or income from investments will be less in the future as inflation decreases the value of money. As inflation increases, the present value of the Fund’s assets and distributions may decline. This risk is more prevalent with respect to fixed income securities held by the Fund.

Roundhill Inverse S&P 500® WeeklyPay™ ETF | Interest Rate Risk [Member]  
Prospectus [Line Items]  
Risk [Text Block]

INTEREST RATE RISK. Interest rate risk is the risk that the value of the debt securities in the Fund’s portfolio will decline because of rising market interest rates. Interest rate risk is generally lower for shorter term debt securities and higher for longer-term debt securities. Duration is a reasonably accurate measure of a debt security’s price sensitivity to changes in interest rates and a common measure of interest rate risk. Duration measures a debt security’s expected life on a present value basis, taking into account the debt security’s yield, interest payments and final maturity. In general, duration represents the expected percentage change in the value of a security for an immediate 1% change in interest rates. For example, the price of a debt security with a three-year duration would be expected to drop by approximately 3% in response to a 1% increase in interest rates. Therefore, prices of debt securities with shorter durations tend to be less sensitive to interest rate changes than debt securities with longer durations. As the value of a debt security changes over time, so will its duration.

Roundhill Inverse S&P 500® WeeklyPay™ ETF | LEGISLATION AND LITIGATION RISK  
Prospectus [Line Items]  
Risk [Text Block]

LEGISLATION AND LITIGATION RISK. Legislation or litigation that affects the value of assets or securities held by the Fund may reduce the value of the Fund. From time to time, various legislative initiatives are proposed that may have a negative impact on certain assets or securities in which the Fund invests. In addition, litigation regarding any of the assets or securities owned by the Fund may negatively impact the value of the Fund Shares. Such legislation or litigation may cause the Fund to lose value or may result in higher portfolio turnover if the Adviser determines to sell such a holding.

Roundhill Inverse S&P 500® WeeklyPay™ ETF | LEVERAGE RISK  
Prospectus [Line Items]  
Risk [Text Block]

LEVERAGE RISK. The Fund obtains investment exposure in excess of its net assets by utilizing leverage and may lose more money in market conditions that are adverse to its investment objectives than a fund that does not utilize leverage. An investment in the Fund is exposed to the risk that an increase in the weekly performance of shares of the S&P 500® ETF will be magnified. This means that an investment in the Fund will be reduced by an amount equal to 1.2% for every 1% weekly increase in the market value of S&P 500® ETF shares, not including the costs of financing leverage and other operating expenses, which would further reduce its value. The Fund could theoretically lose an amount greater than its net assets in the event the market value of S&P 500® ETF shares increase more than 83.33% over a calendar week. Leverage will also have the effect of magnifying any differences in the Fund’s correlation with S&P 500® ETF shares.

Roundhill Inverse S&P 500® WeeklyPay™ ETF | MONEY MARKET INSTRUMENTS RISK  
Prospectus [Line Items]  
Risk [Text Block]

MONEY MARKET INSTRUMENTS RISK. The value of money market instruments may be affected by changing interest rates and by changes in the credit ratings of the investments. If a significant amount of the Fund’s assets are invested in money market instruments, it will be more difficult for the Fund to achieve its investment objectives. An investment in a money market fund is not insured or guaranteed by the FDIC or any other government agency. It is possible to lose money by investing in a money market fund.

Roundhill Inverse S&P 500® WeeklyPay™ ETF | OPERATIONAL RISK  
Prospectus [Line Items]  
Risk [Text Block]

OPERATIONAL RISK. The Fund is subject to risks arising from various operational factors, including, but not limited to, human error, processing and communication errors, errors of the Fund’s service providers, counterparties or other third-parties, failed or inadequate processes and technology or systems failures. The Fund relies on third-parties for a range of services, including custody. Any delay or failure relating to engaging or maintaining such service providers may affect the Fund’s ability to meet its investment objectives. Although the Fund and the Adviser seek to reduce these operational risks through controls and procedures, there is no way to completely protect against such risks.

Roundhill Inverse S&P 500® WeeklyPay™ ETF | SPECIAL TAX RISK  
Prospectus [Line Items]  
Risk [Text Block]

SPECIAL TAX RISK. The Fund intends to qualify annually and to elect to be treated as a regulated investment company under the Internal Revenue Code of 1986, as amended (the “Code”). To qualify for the favorable U.S. federal income tax treatment generally accorded to regulated investment companies, the Fund must, among other things, (i) derive in each taxable year at least 90% of its gross income from dividends, interest, payments with respect to securities loans and gains from the sale or other disposition of stock, securities or foreign currencies or other income derived with respect to its business of investing in such stock, securities or currencies, or net income derived from interests in certain publicly traded partnerships; (ii) diversify its holdings so that, at the end of each quarter of the taxable year, (a) at least 50% of the market value of the Fund’s assets is represented by cash and cash items (including receivables), U.S. government securities, the securities of other regulated investment companies and other securities, with such other securities of any one issuer generally limited for the purposes of this calculation to an amount not greater than 5% of the value of the Fund’s total assets and not greater than 10% of the outstanding voting securities of such issuer, and (b) not more than 25% of the value of its total assets is invested in the securities (other than U.S. government securities or the securities of other regulated investment companies) of any one issuer, or two or more issuers which the Fund controls which are engaged in the same, similar or related trades or businesses, or the securities of one or more of certain publicly traded partnerships; and (iii) distribute at least 90% of its investment company taxable income (which includes, among other items, dividends, interest and net short-term capital gains in excess of net long-term capital losses) and at least 90% of its net tax-exempt interest income each taxable year. There are certain exceptions for failure to qualify if the failure is for reasonable cause or is de minimis, and certain corrective action is taken and certain tax payments are made by the Fund.

 

The authority with regard to swaps entered into by regulated investment companies is unclear both as to the qualification under the income test and the identification of the issuer under the diversification test. The Fund intends to take the position that because the swaps held by the Fund reference securities that the income on the swaps are “other income” from the Fund’s business of investing in stocks and securities. In addition, the Fund intends to manage its investments in the swaps so that neither the exposure to issuer of the referenced security nor the exposure to any one counterparty of the swaps will exceed 25% of the gross value of the Fund’s portfolio at the end of any quarter.

 

If the Fund were to fail to meet the qualifying income test or asset diversification test and fail to qualify as a RIC, it would be taxed in the same manner as an ordinary corporation, and distributions to its shareholders would not be deductible by the Fund in computing its taxable income, which would adversely affect the Fund’s performance.

Roundhill Inverse S&P 500® WeeklyPay™ ETF | STRUCTURAL ETF RISKS  
Prospectus [Line Items]  
Risk [Text Block]

STRUCTURAL ETF RISKS. The Fund is an ETF. Accordingly, it is subject to certain risks associated with its unique structure.

 

Market Participants Risk. Only an Authorized Participant may engage in creation or redemption transactions directly with the Fund, and none of those Authorized Participants is obligated to engage in creation and/or redemption transactions. The Fund has a limited number of institutions that may act as Authorized Participants on an agency basis (i.e., on behalf of other market participants). To the extent that Authorized Participants exit the business or are unable to proceed with creation or redemption orders with respect to the Fund and no other Authorized Participant is able to step forward to create or redeem, Fund Shares may be more likely to trade at a premium or discount to NAV and possibly face trading halts or delisting. The Fund may also rely on a small number of third-party market makers to provide a market for the purchase and sale of Fund Shares but such market makers are under no obligation to do so. Decisions by Authorized Participants or market makers to reduce their role or step away from these activities in times of market stress could inhibit the effectiveness of the arbitrage process in maintaining the relationship between the underlying values of the Fund’s portfolio securities and the Fund’s market price. Any trading halt or other problem relating to the trading activity of these market makers or any issues disrupting the Authorized Participants’ ability to proceed with creation and/or redemption orders could result in a dramatic change in the spread between the Fund’s net asset value and the price at which Fund Shares are trading on the Exchange, which could result in a decrease in value of Fund Shares. This reduced effectiveness could result in Fund Shares trading at a premium or discount to net asset value and also in greater than normal intraday bid-ask spreads Fund Shares.

 

Cash Transactions Risk. The Fund currently expects to effect a significant portion of its creations and redemptions for cash, rather than in-kind securities. Paying redemption proceeds in cash rather than through in-kind delivery of portfolio securities may require the Fund to dispose of or sell portfolio securities or other assets at an inopportune time to obtain the cash needed to meet redemption orders. This may cause the Fund to sell a security and recognize a capital gain or loss that might not have been incurred if it had made a redemption in-kind. As a result, the Fund may pay out higher or lower annual capital gains distributions than ETFs that redeem in-kind. The use of cash creations and redemptions may also cause the Fund’s Shares to trade in the market at greater bid-ask spreads or greater premiums or discounts to the Fund’s net asset value (“NAV”). Furthermore, the Fund may not be able to execute cash transactions for creation and redemption purposes at the same price used to determine the Fund’s NAV. To the extent that the maximum additional charge for creation or redemption transactions is insufficient to cover the execution shortfall, the Fund’s performance could be negatively impacted.

 

Costs of Buying and Selling Fund Shares. Due to the costs of buying or selling Fund Shares, including brokerage commissions imposed by brokers and bid/ask spreads, frequent trading of Fund Shares may significantly reduce investment results and an investment in Fund Shares may not be advisable for investors who anticipate regularly making small investments.

 

Premium/Discount Risk. The trading prices of Fund Shares in the secondary market may differ from the Fund’s daily NAV per Fund Share and there may be times when the market price of the Fund Shares is more than the NAV per Fund Share (premium) or less than the NAV per Fund Share (discount). If a shareholder purchases Fund Shares at a time when the market price is at a premium to the NAV or sells Fund Shares at a time when the market price is at a discount to the NAV, the shareholder may pay more for, or receive less than, the underlying value of the Fund Shares, respectively. This risk is heightened in times of market volatility or periods of steep market declines.

 

Trading Risks. Although Fund Shares are listed for trading on the Exchange and may be traded on U.S. exchanges other than the Exchange, there can be no assurance that Fund Shares will trade with any volume, or at all, on any stock exchange. In stressed market conditions, the liquidity of Fund Shares may begin to mirror the liquidity of the Fund’s underlying portfolio holdings, which can be significantly less liquid than Fund Shares. Trading in Fund Shares on the Exchange may be halted due to market conditions or for reasons that, in the view of the Exchange, make trading in Fund Shares inadvisable. In addition, trading in Fund Shares on the Exchange is subject to trading halts caused by extraordinary market volatility pursuant to the Exchange’s “circuit breaker” rules. There can be no assurance that the requirements of the Exchange necessary to maintain the listing of the Fund will continue to be met or will remain unchanged.

Roundhill Inverse S&P 500® WeeklyPay™ ETF | U.S. GOVERNMENT SECURITIES RISK  
Prospectus [Line Items]  
Risk [Text Block]

U.S. GOVERNMENT SECURITIES RISK. U.S. government securities are subject to interest rate risk but generally do not involve the credit risks associated with investments in other types of debt securities. As a result, the yields available from U.S. government securities are generally lower than the yields available from other debt securities. U.S. government securities are guaranteed only as to the timely payment of interest and the payment of principal when held to maturity.

Roundhill Inverse S&P 500® WeeklyPay™ ETF | VALUATION RISK  
Prospectus [Line Items]  
Risk [Text Block]

VALUATION RISK. The Fund may hold securities or other assets that may be valued on the basis of factors other than market quotations. This may occur because the asset or security does not trade on a centralized exchange, or in times of market turmoil or reduced liquidity. There are multiple methods that can be used to value a portfolio holding when market quotations are not readily available. The value established for any portfolio holding at a point in time might differ from what would be produced using a different methodology or if it had been priced using market quotations. Portfolio holdings that are valued using techniques other than market quotations, including “fair valued” assets or securities, may be subject to greater fluctuation in their valuations from one day to the next than if market quotations were used. In addition, there is no assurance that the Fund could sell or close out a portfolio position for the value established for it at any time, and it is possible that the Fund would incur a loss because a portfolio position is sold or closed out at a discount to the valuation established by the Fund at that time. The Fund’s ability to value investments may be impacted by technological issues or errors by pricing services or other third-party service providers.

Roundhill Inverse S&P 500® WeeklyPay™ ETF | SWAP AGREEMENTS RISK  
Prospectus [Line Items]  
Risk [Text Block]

SWAP AGREEMENTS RISK. The Fund will utilize swap agreements to derive its exposure to shares of the S&P 500® ETF. Swap agreements may involve greater risks than direct investment in securities as they may be leveraged and are subject to credit risk, counterparty risk and valuation risk. A swap agreement could result in losses if the underlying reference or asset does not perform as anticipated. In addition, many swaps trade over-the-counter and may be considered illiquid. It may not be possible for the Fund to liquidate a swap position at an advantageous time or price, which may result in significant losses.

Roundhill Inverse S&P 500® WeeklyPay™ ETF | NEW FUND RISK

NEW FUND RISK. The Fund is a recently organized investment company with a limited operating history. As a result, prospective investors have a limited track record or history on which to base their investment decision.

Roundhill Inverse S&P 500® WeeklyPay™ ETF | INVERSE CORRELATION RISK  
Prospectus [Line Items]  
Risk [Text Block]

INVERSE CORRELATION RISK. The Fund seeks to provide a return equal to -1.2 times (-120%) the calendar week total return of shares of the S&P 500® ETF. This means that the Fund will decrease in value when the S&P 500® ETF increases in value, a result which is the opposite of traditional funds. The more that the S&P 500® ETF increases in value over a given day, the more the Fund will decrease in value.

Risk [Text Block]

S&P 500® ETF INVESTING RISKS. The Fund will have significant exposure to the S&P 500® ETF through its investments in shares of the S&P 500® ETF and swap agreements that utilize the S&P 500® ETF as the reference asset. Accordingly, the Fund will subject to the risks of the S&P 500® ETF, set forth below. In addition to these risks, the S&P 500® ETF is also subject to the following risks to which the Fund is also subject, which are described within the section entitled “Principal Risks”: Market Risk, Asset Class Risk, Concentration Risk, Current Market Conditions Risk, Cybersecurity Risk, Operational Risk and Structural ETF Risk.

 

EQUITY SECURITIES RISK. Equity securities are subject to changes in value, and their values may be more volatile than those of other asset classes. Equity securities prices fluctuate for several reasons, including changes in investors’ perceptions of the financial condition of an issuer or the general condition of the relevant equity market, such as market volatility, or when political or economic events affecting an issuer occur. Common stock prices may be particularly sensitive to rising interest rates, as the cost of capital rises and borrowing costs increase. Common stocks generally subject their holders to more risks than preferred stocks and debt securities because common stockholders’ claims are subordinated to those of holders of preferred stocks and debt securities upon the bankruptcy of the issuer.

 

INDEX-RELATED RISK. The S&P 500® ETF Index Provider may rely on various sources of information to assess the criteria of components of the S&P 500® ETF, including information that may be based on assumptions and estimates. Neither the S&P 500® ETF nor its investment adviser offer assurances that the S&P 500® ETF Index Provider’s methodology or sources of information will provide an accurate assessment of included components or will result in the S&P 500® ETF meeting its investment objective. Errors in index data, index computations or the construction of the S&P 500® ETF Index in accordance with its methodology may occur, and the S&P 500® ETF Index Provider may not identify or correct them promptly or at all, which may have an adverse impact on the S&P 500® ETF and its shareholders. Unusual market conditions or other unforeseen circumstances (such as natural disasters, political unrest or war) may impact the S&P 500® ETF Index Provider or a third-party data provider and could cause the S&P 500® ETF Index Provider to postpone a scheduled rebalance. This could cause the S&P 500® ETF Index to vary from its normal or expected composition.

 

INDIRECT INVESTMENT RISK. The S&P 500® ETF is not affiliated with the Trust, the Fund, the Adviser, the Sub-Adviser or any affiliates thereof and is not involved with this offering in any way, and has no obligation to consider the Fund in taking any actions that might affect the value of the Fund. The Trust, the Fund, the Adviser, the Sub-Adviser or any affiliate are not responsible for the performance of the S&P 500® ETF and make no representation as to the performance the S&P 500® ETF. Investing in the Fund is not equivalent to investing in the S&P 500® ETF Fund. Shareholders will not have voting rights or rights to receive dividends or other distributions or any other rights with respect to the S&P 500® ETF.

 

LARGE CAPITALIZATION COMPANIES RISK. Large capitalization companies may be less able than smaller capitalization companies to adapt to changing market conditions. Large capitalization companies may be more mature and subject to more limited growth potential compared with smaller capitalization companies. During different market cycles, the performance of large capitalization companies has trailed the overall performance of the broader securities markets.

 

UNITED STATES RISK. Certain changes in the U.S. economy, such as when the U.S. economy weakens or when its financial markets decline, may have an adverse effect on the securities to which the Fund has exposure.

Risk [Text Block]

NON-DIVERSIFICATION RISK. As a “non-diversified” fund, the Fund may hold a smaller number of portfolio securities than many other funds. To the extent the Fund invests in a relatively small number of issuers, a decline in the market value of a particular security held by the Fund may affect its value more than if it invested in a larger number of issuers. The value of the Fund Shares may be more volatile than the values of shares of more diversified funds.

Roundhill Investment Grade Bond WeeklyPay™ ETF | MARKET RISK  
Prospectus [Line Items]  
Risk [Text Block]

MARKET RISK. Market risk is the risk that a particular investment, or Fund Shares in general, may fall in value. Securities are subject to market fluctuations caused by real or perceived adverse economic, political, and regulatory factors or market developments, changes in interest rates, disruptions to trade, impositions of tariffs and perceived trends in securities prices. Fund Shares could decline in value or underperform other investments. In addition, local, regional or global events such as war, acts of terrorism, market manipulation, government defaults, government shutdowns, regulatory actions, political changes, diplomatic developments, the imposition of sanctions and other similar measures, spread of infectious diseases or other public health issues, recessions, natural disasters, or other events could have a significant negative impact on the Fund and its investments. Any of such circumstances could have a materially negative impact on the value of Fund Shares, the liquidity of an investment, and may result in increased market volatility. During any such events, Fund Shares may trade at increased premiums or discounts to their net asset value, the bid/ask spread on Fund Shares may widen and the returns on investment may fluctuate.

Roundhill Investment Grade Bond WeeklyPay™ ETF | LIQUIDITY RISK  
Prospectus [Line Items]  
Risk [Text Block]

LIQUIDITY RISK. The market for swap agreements that reference the Investment Grade Bond ETF shares may be subject to periods of illiquidity. During such times it may be difficult or impossible to buy or sell a position at the desired price. Market disruptions or volatility can also make it difficult to find a counterparty willing to transact at a reasonable price and sufficient size. Illiquid markets may cause losses, which could be significant. The large size of the positions which the Fund may acquire increases the risk of illiquidity, may make its positions more difficult to liquidate, and may increase the losses incurred while trying to do so. Such large positions also may impact the price of swap agreements on the Investment Grade Bond ETF shares.

Roundhill Investment Grade Bond WeeklyPay™ ETF | ACTIVE MANAGEMENT RISK  
Prospectus [Line Items]  
Risk [Text Block]

ACTIVE MANAGEMENT RISK. The Fund is actively-managed and its performance reflects investment decisions that the Adviser and/or Sub-Adviser makes for the Fund. Such judgments about the Fund’s investments may prove to be incorrect. If the investments selected and the strategies employed by the Fund fail to produce the intended results, the Fund could underperform as compared to other funds with similar investment objectives and/or strategies, or could have negative returns.

Roundhill Investment Grade Bond WeeklyPay™ ETF | ACTIVE MARKET RISK

ACTIVE MARKET RISK. Although Fund Shares are listed for trading on the Exchange, there can be no assurance that an active trading market for Fund Shares will develop or be maintained. Fund Shares trade on the Exchange at market prices that may be below, at or above the Fund’s net asset value. Securities, including Fund Shares, are subject to market fluctuations and liquidity constraints that may be caused by such factors as economic, political, or regulatory developments, changes in interest rates, and/or perceived trends in securities prices. Fund Shares could decline in value or underperform other investments.

CONCENTRATION RISK. The Fund is susceptible to an increased risk of loss, including losses due to adverse events that affect the Fund’s investments more than the market as a whole, to the extent that the Fund’s investments are concentrated in investments that provide exposure to the Investment Grade Bond ETF and the industry or group of industries to which it is concentrated.

Risk [Text Block]

COUNTERPARTY RISK. Fund transactions involving a counterparty are subject to the risk that the counterparty will not fulfill its obligation to the Fund. Counterparty risk may arise because of the counterparty’s financial condition (i.e., financial difficulties, bankruptcy, or insolvency), market activities and developments, or other reasons, whether foreseen or not. A counterparty’s inability to fulfill its obligation may result in significant financial loss to the Fund. The Fund may be unable to recover its investment from the counterparty or may obtain a limited recovery, and/or recovery may be delayed.

Roundhill Investment Grade Bond WeeklyPay™ ETF | CURRENT MARKET CONDITIONS RISK  
Prospectus [Line Items]  
Risk [Text Block]

CURRENT MARKET CONDITIONS RISK. Current market conditions risk is the risk that a particular investment, or Fund Shares in general, may fall in value due to current market conditions. As a means to fight inflation, which remains at elevated levels, the Federal Reserve and certain foreign central banks have raised interest rates; however, the Federal Reserve has recently lowered interest rates and may continue to do so. U.S. regulators have proposed several changes to market and issuer regulations which would directly impact the Fund, and any regulatory changes could adversely impact the Fund’s ability to achieve its investment strategies or make certain investments. Recent and potential future bank failures could result in disruption to the broader banking industry or markets generally and reduce confidence in financial institutions and the economy as a whole, which may also heighten market volatility and reduce liquidity. Additionally, challenges in commercial real estate markets, including rising interest rates, declining valuations and increasing vacancies, could have a broader impact on financial markets. The ongoing adversarial political climate in the United States, as well as political and diplomatic events both domestic and abroad, have and may continue to have an adverse impact the U.S. regulatory landscape, markets and investor behavior, which could have a negative impact on the Fund’s investments and operations. The change in administration resulting from the 2024 United States national elections could result in significant impacts to international trade relations, tax and immigration policies, and other aspects of the national and international political and financial landscape, which could affect, among other things, inflation and the securities markets generally. Other unexpected political, regulatory and diplomatic events within the U.S. and abroad may affect investor and consumer confidence and may adversely impact financial markets and the broader economy. For example, ongoing armed conflicts between Russia and Ukraine in Europe and among Israel, Iran, Hamas and other militant groups in the Middle East, have caused and could continue to cause significant market disruptions and volatility within the markets in Russia, Europe, the Middle East and the United States. The hostilities and sanctions resulting from those hostilities have and could continue to have a significant impact on certain Fund investments as well as Fund performance and liquidity. The economies of the United States and its trading partners, as well as the financial markets generally, may be adversely impacted by trade disputes, including the imposition of tariffs, and other matters. For example, the United States has imposed trade barriers and restrictions on China. In addition, the Chinese government is engaged in a longstanding dispute with Taiwan, continually threatening an invasion. If the political climate between the United States and China does not improve or continues to deteriorate, if China were to attempt invading Taiwan, or if other geopolitical conflicts develop or worsen, economies, markets and individual securities may be adversely affected, and the value of the Fund’s assets may go down. A public health crisis and the ensuing policies enacted by governments and central banks may cause significant volatility and uncertainty in global financial markets, negatively impacting global growth prospects. As the COVID-19 global pandemic illustrated, such events may affect certain geographic regions, countries, sectors and industries more significantly than others. Advancements in technology may also adversely impact markets and the overall performance of the Fund. For instance, the economy may be significantly impacted by the advanced development and increased regulation of artificial intelligence. Additionally, cyber security breaches of both government and non-government entities could have negative impacts on infrastructure and the ability of such entities, including the Fund, to operate properly. These events, and any other future events, may adversely affect the prices and liquidity of the Fund’s portfolio investments and could result in disruptions in the trading markets.

Roundhill Investment Grade Bond WeeklyPay™ ETF | CYBERSECURITY RISK  
Prospectus [Line Items]  
Risk [Text Block]

CYBERSECURITY RISK. Failures or breaches of the electronic systems of the Fund, the Fund’s adviser, sub-adviser, distributor and other service providers, market makers, Authorized Participants or the issuers of securities in which the Fund invests have the ability to cause disruptions, negatively impact the Fund’s business operations and/or potentially result in financial losses to the Fund and its shareholders. While the Fund has established business continuity plans and risk management systems seeking to address system breaches or failures, there are inherent limitations in such plans and systems. Furthermore, the Fund cannot control the cybersecurity plans and systems of the Fund’s other service providers, market makers, Authorized Participants or issuers of securities in which the Fund invests.

Roundhill Investment Grade Bond WeeklyPay™ ETF | DEBT SECURITIES RISK  
Prospectus [Line Items]  
Risk [Text Block]

DEBT SECURITIES RISK. Investments in debt securities subject the holder to the credit risk of the issuer. Credit risk refers to the possibility that the issuer or other obligor of a security will not be able or willing to make payments of interest and principal when due. Generally, the value of debt securities will change inversely with changes in interest rates. To the extent that interest rates rise, certain underlying obligations may be paid off substantially slower than originally anticipated and the value of those securities may fall sharply. During periods of falling interest rates, the income received by the Fund may decline. If the principal on a debt security is prepaid before expected, the prepayments of principal may have to be reinvested in obligations paying interest at lower rates. Debt securities generally do not trade on a securities exchange making them generally less liquid and more difficult to value than common stock.

Roundhill Investment Grade Bond WeeklyPay™ ETF | DERIVATIVES RISK  
Prospectus [Line Items]  
Risk [Text Block]

DERIVATIVES RISK. The use of derivative instruments involves risks different from, or possibly greater than, the risks associated with investing directly in securities and other traditional investments. These risks include: (i) the risk that the counterparty to a derivative transaction may not fulfill its contractual obligations; (ii) risk of mispricing or improper valuation; and (iii) the risk that changes in the value of the derivative may not correlate perfectly with the underlying asset. Derivative prices are highly volatile and may fluctuate substantially during a short period of time. Such prices are influenced by numerous factors that affect the markets, including, but not limited to: changing supply and demand relationships; government programs and policies; national and international political and economic events, changes in interest rates, inflation and deflation and changes in supply and demand relationships. Trading derivative instruments involves risks different from, or possibly greater than, the risks associated with investing directly in securities. Derivative contracts ordinarily have leverage inherent in their terms. The use of leverage may cause the Fund to liquidate portfolio positions when it would not be advantageous to do so in order to satisfy its obligations or to meet regulatory or contractual requirements for derivatives. The use of derivatives can magnify potential for gain or loss and, therefore, amplify the effects of market volatility on share price.

Roundhill Investment Grade Bond WeeklyPay™ ETF | DISTRIBUTION TAX RISK  
Prospectus [Line Items]  
Risk [Text Block]

DISTRIBUTION TAX RISK. The Fund currently expects to make distributions on a weekly basis. Such frequent distributions may expose investors to increased tax liabilities. However, these distributions may exceed the Fund’s income and gains for the Fund’s taxable year. Distributions in excess of the Fund’s current and accumulated earnings and profits will be treated as a return of capital. A return of capital distribution generally will not be taxable but will reduce the shareholder’s cost basis and will result in a higher capital gain or lower capital loss when those Fund Shares on which the distribution was received are sold. Once a Fund shareholder’s cost basis is reduced to zero, further distributions will be treated as capital gain if the Fund shareholder holds Fund Shares as capital assets. Additionally, any capital returned through distributions will be distributed after payment of Fund fees and expenses. Because a portion of the Fund’s distributions may consist of return of capital, the Fund may not be an appropriate investment for investors who do not want their principal investment in the Fund to decrease over time or who do not wish to receive return of capital in a given period. In the event that a shareholder purchases Fund Shares shortly before a distribution by the Fund, the entire distribution may be taxable to the shareholder even though a portion of the distribution effectively represents a return of the purchase price.

Roundhill Investment Grade Bond WeeklyPay™ ETF | ETF RISK  
Prospectus [Line Items]  
Risk [Text Block]

ETF RISK. The Fund may invest in ETFs. The value of an ETF held by the Fund will fluctuate over time based on fluctuations in the values of the assets held by the ETF, which may be affected by changes in general economic conditions, expectations for future growth and profits, interest rates and the supply and demand for those assets. When the Fund invests in an ETF, it will bear a proportionate share of the ETF’s expenses. Brokerage, tax and other expenses may negatively impact the performance of the ETF and, in turn, the value of the Fund Shares. An ETF that tracks an index may not exactly match the performance of the index due to cash drag, differences between the portfolio of the ETF and the components of the index, expenses and other factors.

Roundhill Investment Grade Bond WeeklyPay™ ETF | INFLATION RISK  
Prospectus [Line Items]  
Risk [Text Block]

INFLATION RISK. Inflation risk is the risk that the value of assets or income from investments will be less in the future as inflation decreases the value of money. As inflation increases, the present value of the Fund’s assets and distributions may decline. This risk is more prevalent with respect to fixed income securities held by the Fund.

Roundhill Investment Grade Bond WeeklyPay™ ETF | Interest Rate Risk [Member]  
Prospectus [Line Items]  
Risk [Text Block]

INTEREST RATE RISK. Interest rate risk is the risk that the value of the debt securities in the Fund’s portfolio will decline because of rising market interest rates. Interest rate risk is generally lower for shorter term debt securities and higher for longer-term debt securities. Duration is a reasonably accurate measure of a debt security’s price sensitivity to changes in interest rates and a common measure of interest rate risk. Duration measures a debt security’s expected life on a present value basis, taking into account the debt security’s yield, interest payments and final maturity. In general, duration represents the expected percentage change in the value of a security for an immediate 1% change in interest rates. For example, the price of a debt security with a three-year duration would be expected to drop by approximately 3% in response to a 1% increase in interest rates. Therefore, prices of debt securities with shorter durations tend to be less sensitive to interest rate changes than debt securities with longer durations. As the value of a debt security changes over time, so will its duration.

Roundhill Investment Grade Bond WeeklyPay™ ETF | LEGISLATION AND LITIGATION RISK  
Prospectus [Line Items]  
Risk [Text Block]

LEGISLATION AND LITIGATION RISK. Legislation or litigation that affects the value of assets or securities held by the Fund may reduce the value of the Fund. From time to time, various legislative initiatives are proposed that may have a negative impact on certain assets or securities in which the Fund invests. In addition, litigation regarding any of the assets or securities owned by the Fund may negatively impact the value of the Shares. Such legislation or litigation may cause the Fund to lose value or may result in higher portfolio turnover if the Adviser determines to sell such a holding.

Roundhill Investment Grade Bond WeeklyPay™ ETF | LEVERAGE RISK  
Prospectus [Line Items]  
Risk [Text Block]

LEVERAGE RISK. The Fund obtains investment exposure in excess of its net assets by utilizing leverage and may lose more money in market conditions that are adverse to its investment objectives than a fund that does not utilize leverage. An investment in the Fund is exposed to the risk that a decline in the weekly performance of shares of the Investment Grade Bond ETF will be magnified. This means that an investment in the Fund will be reduced by an amount equal to 1.2% for every 1% weekly decline in the market value of the Investment Grade Bond ETF shares, not including the costs of financing leverage and other operating expenses, which would further reduce its value. The Fund could theoretically lose an amount greater than its net assets in the event the market value of the Investment Grade Bond ETF shares decline more than 83.33% over a calendar week. Leverage will also have the effect of magnifying any differences in the Fund’s correlation with the Investment Grade Bond ETF shares.

Roundhill Investment Grade Bond WeeklyPay™ ETF | MONEY MARKET INSTRUMENTS RISK  
Prospectus [Line Items]  
Risk [Text Block]

MONEY MARKET INSTRUMENTS RISK. The value of money market instruments may be affected by changing interest rates and by changes in the credit ratings of the investments. If a significant amount of the Fund’s assets are invested in money market instruments, it will be more difficult for the Fund to achieve its investment objectives. An investment in a money market fund is not insured or guaranteed by the FDIC or any other government agency. It is possible to lose money by investing in a money market fund.

Roundhill Investment Grade Bond WeeklyPay™ ETF | OPERATIONAL RISK  
Prospectus [Line Items]  
Risk [Text Block]

OPERATIONAL RISK. The Fund is subject to risks arising from various operational factors, including, but not limited to, human error, processing and communication errors, errors of the Fund’s service providers, counterparties or other third-parties, failed or inadequate processes and technology or systems failures. The Fund relies on third-parties for a range of services, including custody. Any delay or failure relating to engaging or maintaining such service providers may affect the Fund’s ability to meet its investment objectives. Although the Fund and the Adviser seek to reduce these operational risks through controls and procedures, there is no way to completely protect against such risks.

Roundhill Investment Grade Bond WeeklyPay™ ETF | SPECIAL TAX RISK  
Prospectus [Line Items]  
Risk [Text Block]

SPECIAL TAX RISK. The Fund intends to qualify annually and to elect to be treated as a regulated investment company under the Internal Revenue Code of 1986, as amended (the “Code”). To qualify for the favorable U.S. federal income tax treatment generally accorded to regulated investment companies, the Fund must, among other things, (i) derive in each taxable year at least 90% of its gross income from dividends, interest, payments with respect to securities loans and gains from the sale or other disposition of stock, securities or foreign currencies or other income derived with respect to its business of investing in such stock, securities or currencies, or net income derived from interests in certain publicly traded partnerships; (ii) diversify its holdings so that, at the end of each quarter of the taxable year, (a) at least 50% of the market value of the Fund’s assets is represented by cash and cash items (including receivables), U.S. government securities, the securities of other regulated investment companies and other securities, with such other securities of any one issuer generally limited for the purposes of this calculation to an amount not greater than 5% of the value of the Fund’s total assets and not greater than 10% of the outstanding voting securities of such issuer, and (b) not more than 25% of the value of its total assets is invested in the securities (other than U.S. government securities or the securities of other regulated investment companies) of any one issuer, or two or more issuers which the Fund controls which are engaged in the same, similar or related trades or businesses, or the securities of one or more of certain publicly traded partnerships; and (iii) distribute at least 90% of its investment company taxable income (which includes, among other items, dividends, interest and net short-term capital gains in excess of net long-term capital losses) and at least 90% of its net tax-exempt interest income each taxable year. There are certain exceptions for failure to qualify if the failure is for reasonable cause or is de minimis, and certain corrective action is taken and certain tax payments are made by the Fund.

 

The authority with regard to swaps entered into by regulated investment companies is unclear both as to the qualification under the income test and the identification of the issuer under the diversification test. The Fund intends to take the position that because the swaps held by the Fund reference securities that the income on the swaps are “other income” from the Fund’s business of investing in stocks and securities. In addition, the Fund intends to manage its investments in the swaps so that neither the exposure to issuer of the referenced security nor the exposure to any one counterparty of the swaps will exceed 25% of the gross value of the Fund’s portfolio at the end of any quarter.

 

If the Fund were to fail to meet the qualifying income test or asset diversification test and fail to qualify as a RIC, it would be taxed in the same manner as an ordinary corporation, and distributions to its shareholders would not be deductible by the Fund in computing its taxable income, which would adversely affect the Fund’s performance.

Roundhill Investment Grade Bond WeeklyPay™ ETF | STRUCTURAL ETF RISKS  
Prospectus [Line Items]  
Risk [Text Block]

STRUCTURAL ETF RISKS. The Fund is an ETF. Accordingly, it is subject to certain risks associated with its unique structure.

 

Market Participants Risk. Only an Authorized Participant may engage in creation or redemption transactions directly with the Fund, and none of those Authorized Participants is obligated to engage in creation and/or redemption transactions. The Fund has a limited number of institutions that may act as Authorized Participants on an agency basis (i.e., on behalf of other market participants). To the extent that Authorized Participants exit the business or are unable to proceed with creation or redemption orders with respect to the Fund and no other Authorized Participant is able to step forward to create or redeem, Fund Shares may be more likely to trade at a premium or discount to NAV and possibly face trading halts or delisting. The Fund may also rely on a small number of third-party market makers to provide a market for the purchase and sale of Fund Shares but such market makers are under no obligation to do so. Decisions by Authorized Participants or market makers to reduce their role or step away from these activities in times of market stress could inhibit the effectiveness of the arbitrage process in maintaining the relationship between the underlying values of the Fund’s portfolio securities and the Fund’s market price. Any trading halt or other problem relating to the trading activity of these market makers or any issues disrupting the Authorized Participants’ ability to proceed with creation and/or redemption orders could result in a dramatic change in the spread between the Fund’s net asset value and the price at which Fund Shares are trading on the Exchange, which could result in a decrease in value of Fund Shares. This reduced effectiveness could result in Fund Shares trading at a premium or discount to net asset value and also in greater than normal intraday bid-ask spreads Fund Shares.

 

Cash Transactions Risk. The Fund currently expects to effect a significant portion of its creations and redemptions for cash, rather than in-kind securities. Paying redemption proceeds in cash rather than through in-kind delivery of portfolio securities may require the Fund to dispose of or sell portfolio securities or other assets at an inopportune time to obtain the cash needed to meet redemption orders. This may cause the Fund to sell a security and recognize a capital gain or loss that might not have been incurred if it had made a redemption in-kind. As a result, the Fund may pay out higher or lower annual capital gains distributions than ETFs that redeem in-kind. The use of cash creations and redemptions may also cause the Fund’s Shares to trade in the market at greater bid-ask spreads or greater premiums or discounts to the Fund’s NAV. Furthermore, the Fund may not be able to execute cash transactions for creation and redemption purposes at the same price used to determine the Fund’s NAV. To the extent that the maximum additional charge for creation or redemption transactions is insufficient to cover the execution shortfall, the Fund’s performance could be negatively impacted.

 

Costs of Buying and Selling Fund Shares. Due to the costs of buying or selling Fund Shares, including brokerage commissions imposed by brokers and bid/ask spreads, frequent trading of Fund Shares may significantly reduce investment results and an investment in Fund Shares may not be advisable for investors who anticipate regularly making small investments.

 

Premium/Discount Risk. As with all ETFs, Fund Shares may be bought and sold in the secondary market at market prices. The trading prices of Fund Shares in the secondary market may differ from the Fund’s daily net asset value per share and there may be times when the market price of the shares is more than the net asset value per share (premium) or less than the net asset value per share (discount). If a shareholder purchases Fund Shares at a time when the market price is at a premium to the net asset value or sells Fund Shares at a time when the market price is at a discount to the net asset value, the shareholder may pay more for, or receive less than, the underlying value of the Fund Shares, respectively. This risk is heightened in times of market volatility or periods of steep market declines.

 

Trading Risks. Although Fund Shares are listed for trading on the Exchange and may be traded on U.S. exchanges other than the Exchange, there can be no assurance that Fund Shares will trade with any volume, or at all, on any stock exchange. In stressed market conditions, the liquidity of Fund Shares may begin to mirror the liquidity of the Fund’s underlying portfolio holdings, which can be significantly less liquid than Fund Shares. Trading in Fund Shares on the Exchange may be halted due to market conditions or for reasons that, in the view of the Exchange, make trading in Fund Shares inadvisable. In addition, trading in Fund Shares on the Exchange is subject to trading halts caused by extraordinary market volatility pursuant to the Exchange’s “circuit breaker” rules. There can be no assurance that the requirements of the Exchange necessary to maintain the listing of the Fund will continue to be met or will remain unchanged.

Roundhill Investment Grade Bond WeeklyPay™ ETF | U.S. GOVERNMENT SECURITIES RISK  
Prospectus [Line Items]  
Risk [Text Block]

U.S. GOVERNMENT SECURITIES RISK. U.S. government securities are subject to interest rate risk but generally do not involve the credit risks associated with investments in other types of debt securities. As a result, the yields available from U.S. government securities are generally lower than the yields available from other debt securities. U.S. government securities are guaranteed only as to the timely payment of interest and the payment of principal when held to maturity.

Roundhill Investment Grade Bond WeeklyPay™ ETF | VALUATION RISK  
Prospectus [Line Items]  
Risk [Text Block]

VALUATION RISK. The Fund may hold securities or other assets that may be valued on the basis of factors other than market quotations. This may occur because the asset or security does not trade on a centralized exchange, or in times of market turmoil or reduced liquidity. There are multiple methods that can be used to value a portfolio holding when market quotations are not readily available. The value established for any portfolio holding at a point in time might differ from what would be produced using a different methodology or if it had been priced using market quotations. Portfolio holdings that are valued using techniques other than market quotations, including “fair valued” assets or securities, may be subject to greater fluctuation in their valuations from one day to the next than if market quotations were used. In addition, there is no assurance that the Fund could sell or close out a portfolio position for the value established for it at any time, and it is possible that the Fund would incur a loss because a portfolio position is sold or closed out at a discount to the valuation established by the Fund at that time. The Fund’s ability to value investments may be impacted by technological issues or errors by pricing services or other third-party service providers.

Roundhill Investment Grade Bond WeeklyPay™ ETF | EQUITY SECURITIES RISK  
Prospectus [Line Items]  
Risk [Text Block]

EQUITY SECURITIES RISK. Equity securities are subject to changes in value, and their values may be more volatile than those of other asset classes. Equity securities prices fluctuate for several reasons, including changes in investors’ perceptions of the financial condition of an issuer or the general condition of the relevant equity market, such as market volatility, or when political or economic events affecting an issuer occur. Common stock prices may be particularly sensitive to rising interest rates, as the cost of capital rises and borrowing costs increase. Common stocks generally subject their holders to more risks than preferred stocks and debt securities because common stockholders’ claims are subordinated to those of holders of preferred stocks and debt securities upon the bankruptcy of the issuer.

Roundhill Investment Grade Bond WeeklyPay™ ETF | SWAP AGREEMENTS RISK  
Prospectus [Line Items]  
Risk [Text Block]

SWAP AGREEMENTS RISK. The Fund will utilize swap agreements to derive its exposure to shares of the Investment Grade Bond ETF. Swap agreements may involve greater risks than direct investment in securities as they may be leveraged and are subject to credit risk, counterparty risk and valuation risk. A swap agreement could result in losses if the underlying reference or asset does not perform as anticipated. In addition, many swaps trade over-the-counter and may be considered illiquid. It may not be possible for the Fund to liquidate a swap position at an advantageous time or price, which may result in significant losses.

Roundhill Investment Grade Bond WeeklyPay™ ETF | NEW FUND RISK

NEW FUND RISK. The Fund is a recently organized investment company with a limited operating history. As a result, prospective investors have a limited track record or history on which to base their investment decision.

Prospectus [Line Items]  
Risk [Text Block]

REGULATED INVESTMENT COMPANY TAX RISKS. The Fund intends to qualify annually and to elect to be treated as a regulated investment company under the Internal Revenue Code of 1986, as amended (the “Code”). To qualify for the favorable U.S. federal income tax treatment generally accorded to regulated investment companies, the Fund must, among other things, (i) derive in each taxable year at least 90% of its gross income from dividends, interest, payments with respect to securities loans and gains from the sale or other disposition of stock, securities or foreign currencies or other income derived with respect to its business of investing in such stock, securities or currencies, or net income derived from interests in certain publicly traded partnerships; (ii) diversify its holdings so that, at the end of each quarter of the taxable year, (a) at least 50% of the market value of the Fund’s assets is represented by cash and cash items (including receivables), U.S. government securities, the securities of other regulated investment companies and other securities, with such other securities of any one issuer generally limited for the purposes of this calculation to an amount not greater than 5% of the value of the Fund’s total assets and not greater than 10% of the outstanding voting securities of such issuer, and (b) not more than 25% of the value of its total assets is invested in the securities (other than U.S. government securities or the securities of other regulated investment companies) of any one issuer, or two or more issuers which the Fund controls which are engaged in the same, similar or related trades or businesses, or the securities of one or more of certain publicly traded partnerships; and (iii) distribute at least 90% of its investment company taxable income (which includes, among other items, dividends, interest and net short-term capital gains in excess of net long-term capital losses) and at least 90% of its net tax-exempt interest income each taxable year. There are certain exceptions for failure to qualify if the failure is for reasonable cause or is de minimis, and certain corrective action is taken and certain tax payments are made by the Fund.

 

If the Fund were to fail to meet the qualifying income test or asset diversification test and fail to qualify as a RIC, it would be taxed in the same manner as an ordinary corporation, and distributions to its shareholders would not be deductible by the Fund in computing its taxable income, which would adversely affect the Fund’s performance.

Roundhill Investment Grade Bond WeeklyPay™ ETF | LARGE SHAREHOLDER RISK  
Prospectus [Line Items]  
Risk [Text Block]

LARGE SHAREHOLDER RISK. Certain shareholders, including affiliated funds advised by the Adviser, may from time to time own a significant portion of the Fund’s shares. In addition, a third-party investor, the Adviser or an affiliate of the Adviser (“Affiliate”), an authorized participant, a market maker, or another entity may invest in the Fund and hold its investment for a limited period solely to facilitate the commencement of the Fund or to help the Fund achieve a specified size or scale. There can be no assurance that any large shareholder will not redeem its investment, that the size of the Fund will be maintained at such levels, or that the Fund will continue to meet applicable listing requirements. Redemptions by large shareholders could have a significant negative impact on the Fund. In addition, transactions by large shareholders may account for a large percentage of the trading volume on the Fund’s listing exchange and may, therefore, have a material upward or downward effect on the market price of the shares.

 

To the extent that a significant percentage of the Fund’s shares are owned or controlled by a small number of account shareholders (or a single account shareholder), including funds or accounts over which the Adviser or an Affiliate has investment discretion, the Fund is subject to the risk that those shareholders may purchase or redeem Fund shares in significant amounts rapidly or unexpectedly, including as a result of an asset allocation decision made by the Adviser or an Affiliate. This may adversely affect the Fund’s performance if the Adviser is forced to sell portfolio securities or invest cash when it would not otherwise choose to do so. Redemptions of a large number of shares may affect the liquidity of the Fund’s portfolio, increase the Fund’s transaction costs, and accelerate the realization of taxable income and/or gains. In addition, a large redemption could result in the Fund’s current expenses being allocated over a smaller asset base, leading to an increase in the Fund’s gross expense ratio. Large purchases of the Fund’s shares may also adversely affect the Fund’s performance to the extent that the Fund is delayed in investing new cash or otherwise maintains a larger cash position than it ordinarily would, particularly if the Fund accepts cash for an order for the purchase of creation units of the Fund’s shares.

Risk [Text Block]

INVESTMENT GRADE BOND ETF INVESTING RISKS. The Fund will have significant exposure to the Investment Grade Bond ETF through its investments in shares of the Investment Grade Bond ETF and swap agreements that utilize the Investment Grade Bond ETF as the reference asset. Accordingly, the Fund will subject to the risks of the Investment Grade Bond ETF, set forth below. In addition to these risks, the Investment Grade Bond ETF is also subject to the following risks to which the Fund is also subject, which are described within the section entitled “Principal Risks”: Market Risk, Asset Class Risk, Concentration Risk, Credit Risk, Current Market Conditions Risk, Cybersecurity Risk, Debt Securities Risk, ETF Risk, Interest Rate Risk, Operational Risk, Structural ETF Risk, U.S. Government Securities Risk and Valuation Risk.

 

CALL RISK. During periods of falling interest rates, an issuer of a callable bond held by the High Yield Bond ETF may “call” or repay the security before its stated maturity, and the High Yield Bond ETF may have to reinvest the proceeds in securities with lower yields, which would result in a decline in the High Yield Bond ETF’s income, or in securities with greater risks or with other less favorable features.

 

EXTENSION RISK. During periods of rising interest rates, certain debt obligations may be paid off substantially more slowly than originally anticipated and the value of those securities may fall sharply, resulting in a decline in the Investment Grade Bond ETF’s income and potentially in the value of the Investment Grade Bond ETF’s investments.

 

INCOME RISK. The Investment Grade Bond ETF’s income may decline due to falling interest rates or other factors. This can occur because the Investment Grade Bond ETF may be required to invest in lower-yielding bonds when a bond in the Investment Grade Bond ETF’s portfolio matures, is near maturity, is called or is prepaid, when bonds in the Investment Grade Bond ETF Index are substituted, or when the Investment Grade Bond ETF otherwise needs to purchase additional bonds. The Investment Grade Bond ETF Index Provider’s substitution of bonds in the Investment Grade Bond ETF Index may occur, for example, when the time to maturity for the bond no longer matches the Investment Grade Bond ETF Index’s stated maturity guidelines.

 

INDEX-RELATED RISK. The Investment Grade Bond ETF Index Provider may rely on various sources of information to assess the criteria of components of the Investment Grade Bond ETF Index, including information that may be based on assumptions and estimates. Neither the Investment Grade Bond ETF nor its investment adviser offer assurances that the Investment Grade Bond ETF Index Provider’s methodology or sources of information will provide an accurate assessment of included components or will result in the Investment Grade Bond ETF meeting its investment objective. Errors in index data, index computations or the construction of the Investment Grade Bond ETF Index in accordance with its methodology may occur, and the Investment Grade Bond ETF Index Provider may not identify or correct them promptly or at all, which may have an adverse impact on the Investment Grade Bond ETF and its shareholders. Unusual market conditions or other unforeseen circumstances (such as natural disasters, political unrest or war) may impact the Investment Grade Bond ETF Index Provider or a third-party data provider and could cause the Investment Grade Bond ETF Index Provider to postpone a scheduled rebalance. This could cause the Investment Grade Bond ETF Index to vary from its normal or expected composition.

 

INDIRECT INVESTMENT RISK. The Investment Grade Bond ETF is not affiliated with the Trust, the Fund, the Adviser, the Sub-Adviser or any affiliates thereof and is not involved with this offering in any way, and has no obligation to consider the Fund in taking any actions that might affect the value of the Fund. The Trust, the Fund, the Adviser, the Sub-Adviser or any affiliate are not responsible for the performance of the Investment Grade Bond ETF and make no representation as to the performance of the Investment Grade Bond ETF. Investing in the Fund is not equivalent to investing in the Investment Grade Bond ETF Fund shareholders will not have voting rights or rights to receive dividends or other distributions or any other rights with respect to the Investment Grade Bond ETF.

 

RISK OF INVESTING IN CHINA. Investments in Chinese securities, including certain Hong Kong-listed and U.S.-listed securities, subject the Investment Grade Bond ETF to risks specific to China. China may be subject to considerable degrees of economic, political and social instability. China is an emerging market and demonstrates significantly higher volatility from time to time in comparison to developed markets. Over the last few decades, the Chinese government has undertaken reform of economic and market practices and has expanded the sphere of private ownership of property in China. However, Chinese markets generally continue to experience inefficiency, volatility and pricing anomalies resulting from governmental influence, a lack of publicly available information and/or political and social instability. Chinese companies are also subject to the risk that Chinese authorities can intervene in their operations and structure. Internal social unrest or confrontations with neighboring countries, including military conflicts in response to such events, may also disrupt economic development in China and result in a greater risk of currency fluctuations, currency non-convertibility, interest rate fluctuations and higher rates of inflation. China has experienced security concerns, such as terrorism and strained international relations. Additionally, China is alleged to have participated in state-sponsored cyberattacks against foreign companies and foreign governments. Actual and threatened responses to such activity and strained international relations, including purchasing restrictions, sanctions, tariffs or cyberattacks on the Chinese government or Chinese companies, may impact China’s economy and Chinese issuers of securities in which the Investment Grade Bond ETF invests. Incidents involving China’s or the region’s security may cause uncertainty in Chinese markets and may adversely affect the Chinese economy and the Investment Grade Bond ETF’s investments. Export growth continues to be a major driver of China’s rapid economic growth. Reduction in spending on Chinese products and services, supply chain diversification, institution of additional tariffs or other trade barriers (including as a result of heightened trade tensions or a trade war between China and the U.S. or in response to actual or alleged Chinese cyber activity) or a downturn in any of the economies of China’s key trading partners may have an adverse impact on the Chinese economy. The Investment Grade Bond ETF Index may include companies that are subject to economic or trade restrictions (but not investment restrictions) imposed by the U.S. or other governments due to national security, human rights or other concerns of such government. So long as these restrictions do not include restrictions on investments, the Investment Grade Bond ETF is generally expected to invest in such companies, consistent with its objective to track the performance of the Investment Grade Bond ETF Index.

 

Chinese companies, including Chinese companies that are listed on U.S. exchanges, are not subject to the same degree of regulatory requirements, accounting standards or auditor oversight as companies in more developed countries. As a result, information about Chinese securities in which the Investment Grade Bond ETF invests may be less reliable or complete. Chinese companies with securities listed on U.S. exchanges may be delisted if they do not meet U.S. accounting standards and auditor oversight requirements, which would significantly decrease the liquidity and value of the securities. There may be significant obstacles to obtaining information necessary for investigations into or litigation against Chinese companies, and investors may have limited legal remedies. The Investment Grade Bond ETF does not select investments based on investor protection considerations.

 

RISK OF INVESTING IN THE CHINA BOND MARKET. The Investment Grade Bond ETF invests directly in the domestic bond market in the China Interbank Bond Market through the Bond Connect trading channel. All bonds traded through Bond Connect are registered in the name of the PRC’s Central Moneymarkets Unit (“CMU”), which holds such bonds as a nominee owner. The precise nature and rights of the Fund as the beneficial owner of bonds traded in the China Interbank Bond Market through CMU as nominee are relatively new and untested areas of PRC law, and the exact nature of the Investment Grade Bond ETF’s remedies and methods of enforcement of its rights and interests under PRC law are uncertain.

 

Market volatility and potential lack of liquidity due to low trading volume of certain bonds in the China Interbank Bond Market may result in the prices of certain bonds fluctuating significantly. Also, the systems used to trade through Bond Connect may not function as expected. Trading through Bond Connect is also subject to regulatory risks, including laws and regulations that are subject to change. There can be no assurance that Bond Connect or its features or systems will not be materially altered, suspended, discontinued or abolished. The Investment Grade Bond ETF may be subject to additional taxation if certain tax exemptions under PRC tax regulations are withdrawn or amended. Any taxes arising from or to the Investment Grade Bond ETF may be directly borne by, or indirectly passed on to, the Investment Grade Bond ETF, which may substantially impact its net asset value. Investing through Bond Connect subjects the Investment Grade Bond ETF to currency risk, to the extent that currency rates used for Bond Connect are different than the rates used in the China Interbank Bond Market.

 

UNITED STATES RISK. Certain changes in the U.S. economy, such as when the U.S. economy weakens or when its financial markets decline, may have an adverse effect on the securities to which the Fund has exposure.

NON-DIVERSIFICATION RISK. As a “non-diversified” fund, the Fund may hold a smaller number of portfolio securities than many other funds. To the extent the Fund invests in a relatively small number of issuers, a decline in the market value of a particular security held by the Fund may affect its value more than if it invested in a larger number of issuers. The value of the Fund Shares may be more volatile than the values of shares of more diversified funds.

Roundhill Dow 30 WeeklyPay™ ETF | MARKET RISK  
Prospectus [Line Items]  
Risk [Text Block]

MARKET RISK. Market risk is the risk that a particular investment, or Fund Shares in general, may fall in value. Securities are subject to market fluctuations caused by real or perceived adverse economic, political, and regulatory factors or market developments, changes in interest rates, disruptions to trade, impositions of tariffs and perceived trends in securities prices. Fund Shares could decline in value or underperform other investments. In addition, local, regional or global events such as war, acts of terrorism, market manipulation, government defaults, government shutdowns, regulatory actions, political changes, diplomatic developments, the imposition of sanctions and other similar measures, spread of infectious diseases or other public health issues, recessions, natural disasters, or other events could have a significant negative impact on the Fund and its investments. Any of such circumstances could have a materially negative impact on the value of Fund Shares, the liquidity of an investment, and may result in increased market volatility. During any such events, Fund Shares may trade at increased premiums or discounts to their net asset value, the bid/ask spread on Fund Shares may widen and the returns on investment may fluctuate.

Roundhill Dow 30 WeeklyPay™ ETF | LIQUIDITY RISK  
Prospectus [Line Items]  
Risk [Text Block]

LIQUIDITY RISK. The market for swap agreements that reference the Dow 30 ETF shares may be subject to periods of illiquidity. During such times it may be difficult or impossible to buy or sell a position at the desired price. Market disruptions or volatility can also make it difficult to find a counterparty willing to transact at a reasonable price and sufficient size. Illiquid markets may cause losses, which could be significant. The large size of the positions which the Fund may acquire increases the risk of illiquidity, may make its positions more difficult to liquidate, and may increase the losses incurred while trying to do so. Such large positions also may impact the price of swap agreements on the Dow 30 ETF shares.

Roundhill Dow 30 WeeklyPay™ ETF | ACTIVE MANAGEMENT RISK  
Prospectus [Line Items]  
Risk [Text Block]

ACTIVE MANAGEMENT RISK. The Fund is actively-managed and its performance reflects investment decisions that the Adviser and/or Sub-Adviser makes for the Fund. Such judgments about the Fund’s investments may prove to be incorrect. If the investments selected and the strategies employed by the Fund fail to produce the intended results, the Fund could underperform as compared to other funds with similar investment objectives and/or strategies, or could have negative returns.

Roundhill Dow 30 WeeklyPay™ ETF | ACTIVE MARKET RISK  
Prospectus [Line Items]  
Risk [Text Block]

ACTIVE MARKET RISK. Although Fund Shares are listed for trading on the Exchange, there can be no assurance that an active trading market for Fund Shares will develop or be maintained. Fund Shares trade on the Exchange at market prices that may be below, at or above the Fund’s net asset value. Securities, including Fund Shares, are subject to market fluctuations and liquidity constraints that may be caused by such factors as economic, political, or regulatory developments, changes in interest rates, and/or perceived trends in securities prices. Fund Shares could decline in value or underperform other investments.

CONCENTRATION RISK. The Fund is susceptible to an increased risk of loss, including losses due to adverse events that affect the Fund’s investments more than the market as a whole, to the extent that the Fund’s investments are concentrated in investments that provide exposure to the Dow 30 ETF and the industry or group of industries to which it is concentrated.

COUNTERPARTY RISK. Fund transactions involving a counterparty are subject to the risk that the counterparty will not fulfill its obligation to the Fund. Counterparty risk may arise because of the counterparty’s financial condition (i.e., financial difficulties, bankruptcy, or insolvency), market activities and developments, or other reasons, whether foreseen or not. A counterparty’s inability to fulfill its obligation may result in significant financial loss to the Fund. The Fund may be unable to recover its investment from the counterparty or may obtain a limited recovery, and/or recovery may be delayed.

Roundhill Dow 30 WeeklyPay™ ETF | CURRENT MARKET CONDITIONS RISK  
Prospectus [Line Items]  
Risk [Text Block]

CURRENT MARKET CONDITIONS RISK. Current market conditions risk is the risk that a particular investment, or Fund Shares in general, may fall in value due to current market conditions. As a means to fight inflation, which remains at elevated levels, the Federal Reserve and certain foreign central banks have raised interest rates; however, the Federal Reserve has recently lowered interest rates and may continue to do so. U.S. regulators have proposed several changes to market and issuer regulations which would directly impact the Fund, and any regulatory changes could adversely impact the Fund’s ability to achieve its investment strategies or make certain investments. Recent and potential future bank failures could result in disruption to the broader banking industry or markets generally and reduce confidence in financial institutions and the economy as a whole, which may also heighten market volatility and reduce liquidity. Additionally, challenges in commercial real estate markets, including rising interest rates, declining valuations and increasing vacancies, could have a broader impact on financial markets. The ongoing adversarial political climate in the United States, as well as political and diplomatic events both domestic and abroad, have and may continue to have an adverse impact the U.S. regulatory landscape, markets and investor behavior, which could have a negative impact on the Fund’s investments and operations. The change in administration resulting from the 2024 United States national elections could result in significant impacts to international trade relations, tax and immigration policies, and other aspects of the national and international political and financial landscape, which could affect, among other things, inflation and the securities markets generally. Other unexpected political, regulatory and diplomatic events within the U.S. and abroad may affect investor and consumer confidence and may adversely impact financial markets and the broader economy. For example, ongoing armed conflicts between Russia and Ukraine in Europe and among Israel, Iran, Hamas and other militant groups in the Middle East, have caused and could continue to cause significant market disruptions and volatility within the markets in Russia, Europe, the Middle East and the United States. The hostilities and sanctions resulting from those hostilities have and could continue to have a significant impact on certain Fund investments as well as Fund performance and liquidity. The economies of the United States and its trading partners, as well as the financial markets generally, may be adversely impacted by trade disputes, including the imposition of tariffs, and other matters. For example, the United States has imposed trade barriers and restrictions on China. In addition, the Chinese government is engaged in a longstanding dispute with Taiwan, continually threatening an invasion. If the political climate between the United States and China does not improve or continues to deteriorate, if China were to attempt invading Taiwan, or if other geopolitical conflicts develop or worsen, economies, markets and individual securities may be adversely affected, and the value of the Fund’s assets may go down. A public health crisis and the ensuing policies enacted by governments and central banks may cause significant volatility and uncertainty in global financial markets, negatively impacting global growth prospects. As the COVID-19 global pandemic illustrated, such events may affect certain geographic regions, countries, sectors and industries more significantly than others. Advancements in technology may also adversely impact markets and the overall performance of the Fund. For instance, the economy may be significantly impacted by the advanced development and increased regulation of artificial intelligence. Additionally, cyber security breaches of both government and non-government entities could have negative impacts on infrastructure and the ability of such entities, including the Fund, to operate properly. These events, and any other future events, may adversely affect the prices and liquidity of the Fund’s portfolio investments and could result in disruptions in the trading markets.

Roundhill Dow 30 WeeklyPay™ ETF | CYBERSECURITY RISK  
Prospectus [Line Items]  
Risk [Text Block]

CYBERSECURITY RISK. Failures or breaches of the electronic systems of the Fund, the Fund’s adviser, sub-adviser, distributor and other service providers, market makers, Authorized Participants or the issuers of securities in which the Fund invests have the ability to cause disruptions, negatively impact the Fund’s business operations and/or potentially result in financial losses to the Fund and its shareholders. While the Fund has established business continuity plans and risk management systems seeking to address system breaches or failures, there are inherent limitations in such plans and systems. Furthermore, the Fund cannot control the cybersecurity plans and systems of the Fund’s other service providers, market makers, Authorized Participants or issuers of securities in which the Fund invests.

Roundhill Dow 30 WeeklyPay™ ETF | DEBT SECURITIES RISK  
Prospectus [Line Items]  
Risk [Text Block]

DEBT SECURITIES RISK. Investments in debt securities subject the holder to the credit risk of the issuer. Credit risk refers to the possibility that the issuer or other obligor of a security will not be able or willing to make payments of interest and principal when due. Generally, the value of debt securities will change inversely with changes in interest rates. To the extent that interest rates rise, certain underlying obligations may be paid off substantially slower than originally anticipated and the value of those securities may fall sharply. During periods of falling interest rates, the income received by the Fund may decline. If the principal on a debt security is prepaid before expected, the prepayments of principal may have to be reinvested in obligations paying interest at lower rates. Debt securities generally do not trade on a securities exchange making them generally less liquid and more difficult to value than common stock.

Roundhill Dow 30 WeeklyPay™ ETF | DERIVATIVES RISK  
Prospectus [Line Items]  
Risk [Text Block]

DERIVATIVES RISK. The use of derivative instruments involves risks different from, or possibly greater than, the risks associated with investing directly in securities and other traditional investments. These risks include: (i) the risk that the counterparty to a derivative transaction may not fulfill its contractual obligations; (ii) risk of mispricing or improper valuation; and (iii) the risk that changes in the value of the derivative may not correlate perfectly with the underlying asset. Derivative prices are highly volatile and may fluctuate substantially during a short period of time. Such prices are influenced by numerous factors that affect the markets, including, but not limited to: changing supply and demand relationships; government programs and policies; national and international political and economic events, changes in interest rates, inflation and deflation and changes in supply and demand relationships. Trading derivative instruments involves risks different from, or possibly greater than, the risks associated with investing directly in securities. Derivative contracts ordinarily have leverage inherent in their terms. The use of leverage may cause the Fund to liquidate portfolio positions when it would not be advantageous to do so in order to satisfy its obligations or to meet regulatory or contractual requirements for derivatives. The use of derivatives can magnify potential for gain or loss and, therefore, amplify the effects of market volatility on share price.

Roundhill Dow 30 WeeklyPay™ ETF | DISTRIBUTION TAX RISK  
Prospectus [Line Items]  
Risk [Text Block]

DISTRIBUTION TAX RISK. The Fund currently expects to make distributions on a weekly basis. Such frequent distributions may expose investors to increased tax liabilities. However, these distributions may exceed the Fund’s income and gains for the Fund’s taxable year. Distributions in excess of the Fund’s current and accumulated earnings and profits will be treated as a return of capital. A return of capital distribution generally will not be taxable but will reduce the shareholder’s cost basis and will result in a higher capital gain or lower capital loss when those Fund Shares on which the distribution was received are sold. Once a Fund shareholder’s cost basis is reduced to zero, further distributions will be treated as capital gain if the Fund shareholder holds Fund Shares as capital assets. Additionally, any capital returned through distributions will be distributed after payment of Fund fees and expenses. Because a portion of the Fund’s distributions may consist of return of capital, the Fund may not be an appropriate investment for investors who do not want their principal investment in the Fund to decrease over time or who do not wish to receive return of capital in a given period. In the event that a shareholder purchases Fund Shares shortly before a distribution by the Fund, the entire distribution may be taxable to the shareholder even though a portion of the distribution effectively represents a return of the purchase price.

Roundhill Dow 30 WeeklyPay™ ETF | ETF RISK  
Prospectus [Line Items]  
Risk [Text Block]

ETF RISK. The Fund may invest in ETFs. The value of an ETF held by the Fund will fluctuate over time based on fluctuations in the values of the assets held by the ETF, which may be affected by changes in general economic conditions, expectations for future growth and profits, interest rates and the supply and demand for those assets. When the Fund invests in an ETF, it will bear a proportionate share of the ETF’s expenses. Brokerage, tax and other expenses may negatively impact the performance of the ETF and, in turn, the value of the Fund Shares. An ETF that tracks an index may not exactly match the performance of the index due to cash drag, differences between the portfolio of the ETF and the components of the index, expenses and other factors.

Roundhill Dow 30 WeeklyPay™ ETF | INFLATION RISK  
Prospectus [Line Items]  
Risk [Text Block]

INFLATION RISK. Inflation risk is the risk that the value of assets or income from investments will be less in the future as inflation decreases the value of money. As inflation increases, the present value of the Fund’s assets and distributions may decline. This risk is more prevalent with respect to fixed income securities held by the Fund.

Roundhill Dow 30 WeeklyPay™ ETF | Interest Rate Risk [Member]  
Prospectus [Line Items]  
Risk [Text Block]

INTEREST RATE RISK. Interest rate risk is the risk that the value of the debt securities in the Fund’s portfolio will decline because of rising market interest rates. Interest rate risk is generally lower for shorter term debt securities and higher for longer-term debt securities. Duration is a reasonably accurate measure of a debt security’s price sensitivity to changes in interest rates and a common measure of interest rate risk. Duration measures a debt security’s expected life on a present value basis, taking into account the debt security’s yield, interest payments and final maturity. In general, duration represents the expected percentage change in the value of a security for an immediate 1% change in interest rates. For example, the price of a debt security with a three-year duration would be expected to drop by approximately 3% in response to a 1% increase in interest rates. Therefore, prices of debt securities with shorter durations tend to be less sensitive to interest rate changes than debt securities with longer durations. As the value of a debt security changes over time, so will its duration.

Roundhill Dow 30 WeeklyPay™ ETF | LEGISLATION AND LITIGATION RISK  
Prospectus [Line Items]  
Risk [Text Block]

LEGISLATION AND LITIGATION RISK. Legislation or litigation that affects the value of assets or securities held by the Fund may reduce the value of the Fund. From time to time, various legislative initiatives are proposed that may have a negative impact on certain assets or securities in which the Fund invests. In addition, litigation regarding any of the assets or securities owned by the Fund may negatively impact the value of the Shares. Such legislation or litigation may cause the Fund to lose value or may result in higher portfolio turnover if the Adviser determines to sell such a holding.

Roundhill Dow 30 WeeklyPay™ ETF | LEVERAGE RISK  
Prospectus [Line Items]  
Risk [Text Block]

LEVERAGE RISK. The Fund obtains investment exposure in excess of its net assets by utilizing leverage and may lose more money in market conditions that are adverse to its investment objectives than a fund that does not utilize leverage. An investment in the Fund is exposed to the risk that a decline in the weekly performance of shares of the Dow 30 ETF will be magnified. This means that an investment in the Fund will be reduced by an amount equal to 1.2% for every 1% weekly decline in the market value of the Dow 30 ETF shares, not including the costs of financing leverage and other operating expenses, which would further reduce its value. The Fund could theoretically lose an amount greater than its net assets in the event the market value of the Dow 30 ETF shares decline more than 83.33% over a calendar week. Leverage will also have the effect of magnifying any differences in the Fund’s correlation with the Dow 30 ETF shares.

Roundhill Dow 30 WeeklyPay™ ETF | MONEY MARKET INSTRUMENTS RISK  
Prospectus [Line Items]  
Risk [Text Block]

MONEY MARKET INSTRUMENTS RISK. The value of money market instruments may be affected by changing interest rates and by changes in the credit ratings of the investments. If a significant amount of the Fund’s assets are invested in money market instruments, it will be more difficult for the Fund to achieve its investment objectives. An investment in a money market fund is not insured or guaranteed by the FDIC or any other government agency. It is possible to lose money by investing in a money market fund.

Roundhill Dow 30 WeeklyPay™ ETF | OPERATIONAL RISK  
Prospectus [Line Items]  
Risk [Text Block]

OPERATIONAL RISK. The Fund is subject to risks arising from various operational factors, including, but not limited to, human error, processing and communication errors, errors of the Fund’s service providers, counterparties or other third-parties, failed or inadequate processes and technology or systems failures. The Fund relies on third-parties for a range of services, including custody. Any delay or failure relating to engaging or maintaining such service providers may affect the Fund’s ability to meet its investment objectives. Although the Fund and the Adviser seek to reduce these operational risks through controls and procedures, there is no way to completely protect against such risks.

Roundhill Dow 30 WeeklyPay™ ETF | SPECIAL TAX RISK  
Prospectus [Line Items]  
Risk [Text Block]

SPECIAL TAX RISK. The Fund intends to qualify annually and to elect to be treated as a regulated investment company under the Internal Revenue Code of 1986, as amended (the “Code”). To qualify for the favorable U.S. federal income tax treatment generally accorded to regulated investment companies, the Fund must, among other things, (i) derive in each taxable year at least 90% of its gross income from dividends, interest, payments with respect to securities loans and gains from the sale or other disposition of stock, securities or foreign currencies or other income derived with respect to its business of investing in such stock, securities or currencies, or net income derived from interests in certain publicly traded partnerships; (ii) diversify its holdings so that, at the end of each quarter of the taxable year, (a) at least 50% of the market value of the Fund’s assets is represented by cash and cash items (including receivables), U.S. government securities, the securities of other regulated investment companies and other securities, with such other securities of any one issuer generally limited for the purposes of this calculation to an amount not greater than 5% of the value of the Fund’s total assets and not greater than 10% of the outstanding voting securities of such issuer, and (b) not more than 25% of the value of its total assets is invested in the securities (other than U.S. government securities or the securities of other regulated investment companies) of any one issuer, or two or more issuers which the Fund controls which are engaged in the same, similar or related trades or businesses, or the securities of one or more of certain publicly traded partnerships; and (iii) distribute at least 90% of its investment company taxable income (which includes, among other items, dividends, interest and net short-term capital gains in excess of net long-term capital losses) and at least 90% of its net tax-exempt interest income each taxable year. There are certain exceptions for failure to qualify if the failure is for reasonable cause or is de minimis, and certain corrective action is taken and certain tax payments are made by the Fund.

 

The authority with regard to swaps entered into by regulated investment companies is unclear both as to the qualification under the income test and the identification of the issuer under the diversification test. The Fund intends to take the position that because the swaps held by the Fund reference securities that the income on the swaps are “other income” from the Fund’s business of investing in stocks and securities. In addition, the Fund intends to manage its investments in the swaps so that neither the exposure to issuer of the referenced security nor the exposure to any one counterparty of the swaps will exceed 25% of the gross value of the Fund’s portfolio at the end of any quarter.

 

If the Fund were to fail to meet the qualifying income test or asset diversification test and fail to qualify as a RIC, it would be taxed in the same manner as an ordinary corporation, and distributions to its shareholders would not be deductible by the Fund in computing its taxable income, which would adversely affect the Fund’s performance.

Roundhill Dow 30 WeeklyPay™ ETF | STRUCTURAL ETF RISKS  
Prospectus [Line Items]  
Risk [Text Block]

STRUCTURAL ETF RISKS. The Fund is an ETF. Accordingly, it is subject to certain risks associated with its unique structure.

 

Market Participants Risk. Only an Authorized Participant may engage in creation or redemption transactions directly with the Fund, and none of those Authorized Participants is obligated to engage in creation and/or redemption transactions. The Fund has a limited number of institutions that may act as Authorized Participants on an agency basis (i.e., on behalf of other market participants). To the extent that Authorized Participants exit the business or are unable to proceed with creation or redemption orders with respect to the Fund and no other Authorized Participant is able to step forward to create or redeem, Fund Shares may be more likely to trade at a premium or discount to NAV and possibly face trading halts or delisting. The Fund may also rely on a small number of third-party market makers to provide a market for the purchase and sale of Fund Shares but such market makers are under no obligation to do so. Decisions by Authorized Participants or market makers to reduce their role or step away from these activities in times of market stress could inhibit the effectiveness of the arbitrage process in maintaining the relationship between the underlying values of the Fund’s portfolio securities and the Fund’s market price. Any trading halt or other problem relating to the trading activity of these market makers or any issues disrupting the Authorized Participants’ ability to proceed with creation and/or redemption orders could result in a dramatic change in the spread between the Fund’s net asset value and the price at which Fund Shares are trading on the Exchange, which could result in a decrease in value of Fund Shares. This reduced effectiveness could result in Fund Shares trading at a premium or discount to net asset value and also in greater than normal intraday bid-ask spreads Fund Shares.

 

Cash Transactions Risk. The Fund currently expects to effect a significant portion of its creations and redemptions for cash, rather than in-kind securities. Paying redemption proceeds in cash rather than through in-kind delivery of portfolio securities may require the Fund to dispose of or sell portfolio securities or other assets at an inopportune time to obtain the cash needed to meet redemption orders. This may cause the Fund to sell a security and recognize a capital gain or loss that might not have been incurred if it had made a redemption in-kind. As a result, the Fund may pay out higher or lower annual capital gains distributions than ETFs that redeem in-kind. The use of cash creations and redemptions may also cause the Fund’s Shares to trade in the market at greater bid-ask spreads or greater premiums or discounts to the Fund’s NAV. Furthermore, the Fund may not be able to execute cash transactions for creation and redemption purposes at the same price used to determine the Fund’s NAV. To the extent that the maximum additional charge for creation or redemption transactions is insufficient to cover the execution shortfall, the Fund’s performance could be negatively impacted.

 

Costs of Buying and Selling Fund Shares. Due to the costs of buying or selling Fund Shares, including brokerage commissions imposed by brokers and bid/ask spreads, frequent trading of Fund Shares may significantly reduce investment results and an investment in Fund Shares may not be advisable for investors who anticipate regularly making small investments.

 

Premium/Discount Risk. As with all ETFs, Fund Shares may be bought and sold in the secondary market at market prices. The trading prices of Fund Shares in the secondary market may differ from the Fund’s daily net asset value per share and there may be times when the market price of the shares is more than the net asset value per share (premium) or less than the net asset value per share (discount). If a shareholder purchases Fund Shares at a time when the market price is at a premium to the net asset value or sells Fund Shares at a time when the market price is at a discount to the net asset value, the shareholder may pay more for, or receive less than, the underlying value of the Fund Shares, respectively. This risk is heightened in times of market volatility or periods of steep market declines.

 

Trading Risks. Although Fund Shares are listed for trading on the Exchange and may be traded on U.S. exchanges other than the Exchange, there can be no assurance that Fund Shares will trade with any volume, or at all, on any stock exchange. In stressed market conditions, the liquidity of Fund Shares may begin to mirror the liquidity of the Fund’s underlying portfolio holdings, which can be significantly less liquid than Fund Shares. Trading in Fund Shares on the Exchange may be halted due to market conditions or for reasons that, in the view of the Exchange, make trading in Fund Shares inadvisable. In addition, trading in Fund Shares on the Exchange is subject to trading halts caused by extraordinary market volatility pursuant to the Exchange’s “circuit breaker” rules. There can be no assurance that the requirements of the Exchange necessary to maintain the listing of the Fund will continue to be met or will remain unchanged.

Roundhill Dow 30 WeeklyPay™ ETF | U.S. GOVERNMENT SECURITIES RISK  
Prospectus [Line Items]  
Risk [Text Block]

U.S. GOVERNMENT SECURITIES RISK. U.S. government securities are subject to interest rate risk but generally do not involve the credit risks associated with investments in other types of debt securities. As a result, the yields available from U.S. government securities are generally lower than the yields available from other debt securities. U.S. government securities are guaranteed only as to the timely payment of interest and the payment of principal when held to maturity.

Roundhill Dow 30 WeeklyPay™ ETF | VALUATION RISK  
Prospectus [Line Items]  
Risk [Text Block]

VALUATION RISK. The Fund may hold securities or other assets that may be valued on the basis of factors other than market quotations. This may occur because the asset or security does not trade on a centralized exchange, or in times of market turmoil or reduced liquidity. There are multiple methods that can be used to value a portfolio holding when market quotations are not readily available. The value established for any portfolio holding at a point in time might differ from what would be produced using a different methodology or if it had been priced using market quotations. Portfolio holdings that are valued using techniques other than market quotations, including “fair valued” assets or securities, may be subject to greater fluctuation in their valuations from one day to the next than if market quotations were used. In addition, there is no assurance that the Fund could sell or close out a portfolio position for the value established for it at any time, and it is possible that the Fund would incur a loss because a portfolio position is sold or closed out at a discount to the valuation established by the Fund at that time. The Fund’s ability to value investments may be impacted by technological issues or errors by pricing services or other third-party service providers.

Roundhill Dow 30 WeeklyPay™ ETF | EQUITY SECURITIES RISK  
Prospectus [Line Items]  
Risk [Text Block]

EQUITY SECURITIES RISK. Equity securities are subject to changes in value, and their values may be more volatile than those of other asset classes. Equity securities prices fluctuate for several reasons, including changes in investors’ perceptions of the financial condition of an issuer or the general condition of the relevant equity market, such as market volatility, or when political or economic events affecting an issuer occur. Common stock prices may be particularly sensitive to rising interest rates, as the cost of capital rises and borrowing costs increase. Common stocks generally subject their holders to more risks than preferred stocks and debt securities because common stockholders’ claims are subordinated to those of holders of preferred stocks and debt securities upon the bankruptcy of the issuer.

Roundhill Dow 30 WeeklyPay™ ETF | SWAP AGREEMENTS RISK  
Prospectus [Line Items]  
Risk [Text Block]

SWAP AGREEMENTS RISK. The Fund will utilize swap agreements to derive its exposure to shares of the Dow 30 ETF. Swap agreements may involve greater risks than direct investment in securities as they may be leveraged and are subject to credit risk, counterparty risk and valuation risk. A swap agreement could result in losses if the underlying reference or asset does not perform as anticipated. In addition, many swaps trade over-the-counter and may be considered illiquid. It may not be possible for the Fund to liquidate a swap position at an advantageous time or price, which may result in significant losses.

Roundhill Dow 30 WeeklyPay™ ETF | NEW FUND RISK

NEW FUND RISK. The Fund is a recently organized investment company with a limited operating history. As a result, prospective investors have a limited track record or history on which to base their investment decision.

Roundhill Dow 30 WeeklyPay™ ETF | REGULATED INVESTMENT COMPANY TAX RISKS  
Prospectus [Line Items]  
Risk [Text Block]

REGULATED INVESTMENT COMPANY TAX RISKS. The Fund intends to qualify annually and to elect to be treated as a regulated investment company under the Internal Revenue Code of 1986, as amended (the “Code”). To qualify for the favorable U.S. federal income tax treatment generally accorded to regulated investment companies, the Fund must, among other things, (i) derive in each taxable year at least 90% of its gross income from dividends, interest, payments with respect to securities loans and gains from the sale or other disposition of stock, securities or foreign currencies or other income derived with respect to its business of investing in such stock, securities or currencies, or net income derived from interests in certain publicly traded partnerships; (ii) diversify its holdings so that, at the end of each quarter of the taxable year, (a) at least 50% of the market value of the Fund’s assets is represented by cash and cash items (including receivables), U.S. government securities, the securities of other regulated investment companies and other securities, with such other securities of any one issuer generally limited for the purposes of this calculation to an amount not greater than 5% of the value of the Fund’s total assets and not greater than 10% of the outstanding voting securities of such issuer, and (b) not more than 25% of the value of its total assets is invested in the securities (other than U.S. government securities or the securities of other regulated investment companies) of any one issuer, or two or more issuers which the Fund controls which are engaged in the same, similar or related trades or businesses, or the securities of one or more of certain publicly traded partnerships; and (iii) distribute at least 90% of its investment company taxable income (which includes, among other items, dividends, interest and net short-term capital gains in excess of net long-term capital losses) and at least 90% of its net tax-exempt interest income each taxable year. There are certain exceptions for failure to qualify if the failure is for reasonable cause or is de minimis, and certain corrective action is taken and certain tax payments are made by the Fund.

 

If the Fund were to fail to meet the qualifying income test or asset diversification test and fail to qualify as a RIC, it would be taxed in the same manner as an ordinary corporation, and distributions to its shareholders would not be deductible by the Fund in computing its taxable income, which would adversely affect the Fund’s performance.

Roundhill Dow 30 WeeklyPay™ ETF | LARGE SHAREHOLDER RISK  
Prospectus [Line Items]  
Risk [Text Block]

LARGE SHAREHOLDER RISK. Certain shareholders, including affiliated funds advised by the Adviser, may from time to time own a significant portion of the Fund’s shares. In addition, a third-party investor, the Adviser or an affiliate of the Adviser (“Affiliate”), an authorized participant, a market maker, or another entity may invest in the Fund and hold its investment for a limited period solely to facilitate the commencement of the Fund or to help the Fund achieve a specified size or scale. There can be no assurance that any large shareholder will not redeem its investment, that the size of the Fund will be maintained at such levels, or that the Fund will continue to meet applicable listing requirements. Redemptions by large shareholders could have a significant negative impact on the Fund. In addition, transactions by large shareholders may account for a large percentage of the trading volume on the Fund’s listing exchange and may, therefore, have a material upward or downward effect on the market price of the shares.

 

To the extent that a significant percentage of the Fund’s shares are owned or controlled by a small number of account shareholders (or a single account shareholder), including funds or accounts over which the Adviser or an Affiliate has investment discretion, the Fund is subject to the risk that those shareholders may purchase or redeem Fund shares in significant amounts rapidly or unexpectedly, including as a result of an asset allocation decision made by the Adviser or an Affiliate. This may adversely affect the Fund’s performance if the Adviser is forced to sell portfolio securities or invest cash when it would not otherwise choose to do so. Redemptions of a large number of shares may affect the liquidity of the Fund’s portfolio, increase the Fund’s transaction costs, and accelerate the realization of taxable income and/or gains. In addition, a large redemption could result in the Fund’s current expenses being allocated over a smaller asset base, leading to an increase in the Fund’s gross expense ratio. Large purchases of the Fund’s shares may also adversely affect the Fund’s performance to the extent that the Fund is delayed in investing new cash or otherwise maintains a larger cash position than it ordinarily would, particularly if the Fund accepts cash for an order for the purchase of creation units of the Fund’s shares.

Roundhill Dow 30 WeeklyPay™ ETF | DOW 30 ETF INVESTING RISKS  
Prospectus [Line Items]  
Risk [Text Block]

DOW 30 ETF INVESTING RISKS. The Fund will have significant exposure to the Dow 30 ETF through its investments in shares of the Dow 30 ETF and swap agreements that utilize the Dow 30 ETF as the reference asset. Accordingly, the Fund will subject to the risks of the Dow 30 ETF, set forth below. In addition to these risks, the Dow 30 ETF is also subject to the following risks to which the Fund is also subject, which are described within the section entitled “Principal Risks”: Market Risk, Asset Class Risk, Concentration Risk, Current Market Conditions Risk, Cybersecurity Risk, Equity Securities Risk, Operational Risk and Structural ETF Risk.

 

INDEX-RELATED RISK. The Dow 30 ETF Index Provider may rely on various sources of information to assess the criteria of components of the Dow 30 ETF Index, including information that may be based on assumptions and estimates. Neither the Dow 30 ETF nor its investment adviser offer assurances that the Dow 30 ETF Index Provider’s methodology or sources of information will provide an accurate assessment of included components or will result in the Dow 30 ETF meeting its investment objective. Errors in index data, index computations or the construction of the Dow 30 ETF Index in accordance with its methodology may occur, and the Dow 30 ETF Index Provider may not identify or correct them promptly or at all, which may have an adverse impact on the Dow 30 ETF and its shareholders. Unusual market conditions or other unforeseen circumstances (such as natural disasters, political unrest or war) may impact the Dow 30 ETF Index Provider or a third-party data provider and could cause the Dow 30 ETF Index Provider to postpone a scheduled rebalance. This could cause the Dow 30 ETF Index to vary from its normal or expected composition.

 

INDIRECT INVESTMENT RISK. The Dow 30 ETF is not affiliated with the Trust, the Fund, the Adviser, the Sub-Adviser or any affiliates thereof and is not involved with this offering in any way, and has no obligation to consider the Fund in taking any actions that might affect the value of the Fund. The Trust, the Fund, the Adviser, the Sub-Adviser or any affiliate are not responsible for the performance of the Dow 30 ETF and make no representation as to the performance of the Dow 30 ETF. Investing in the Fund is not equivalent to investing in the Dow 30 ETF Fund shareholders will not have voting rights or rights to receive dividends or other distributions or any other rights with respect to the Dow 30 ETF.

 

LARGE CAPITALIZATION COMPANIES RISK. Large capitalization companies may be less able than smaller capitalization companies to adapt to changing market conditions. Large capitalization companies may be more mature and subject to more limited growth potential compared with smaller capitalization companies. During different market cycles, the performance of large capitalization companies has trailed the overall performance of the broader securities markets.

 

UNITED STATES RISK. Certain changes in the U.S. economy, such as when the U.S. economy weakens or when its financial markets decline, may have an adverse effect on the securities to which the Fund has exposure.

NON-DIVERSIFICATION RISK. As a “non-diversified” fund, the Fund may hold a smaller number of portfolio securities than many other funds. To the extent the Fund invests in a relatively small number of issuers, a decline in the market value of a particular security held by the Fund may affect its value more than if it invested in a larger number of issuers. The value of the Fund Shares may be more volatile than the values of shares of more diversified funds.

Roundhill Emerging Markets WeeklyPay™ ETF | MARKET RISK  
Prospectus [Line Items]  
Risk [Text Block]

MARKET RISK. Market risk is the risk that a particular investment, or Fund Shares in general, may fall in value. Securities are subject to market fluctuations caused by real or perceived adverse economic, political, and regulatory factors or market developments, changes in interest rates, disruptions to trade, impositions of tariffs and perceived trends in securities prices. Fund Shares could decline in value or underperform other investments. In addition, local, regional or global events such as war, acts of terrorism, market manipulation, government defaults, government shutdowns, regulatory actions, political changes, diplomatic developments, the imposition of sanctions and other similar measures, spread of infectious diseases or other public health issues, recessions, natural disasters, or other events could have a significant negative impact on the Fund and its investments. Any of such circumstances could have a materially negative impact on the value of Fund Shares, the liquidity of an investment, and may result in increased market volatility. During any such events, Fund Shares may trade at increased premiums or discounts to their net asset value, the bid/ask spread on Fund Shares may widen and the returns on investment may fluctuate.

Roundhill Emerging Markets WeeklyPay™ ETF | LIQUIDITY RISK  
Prospectus [Line Items]  
Risk [Text Block]

LIQUIDITY RISK. The market for swap agreements that reference the Emerging Markets ETF shares may be subject to periods of illiquidity. During such times it may be difficult or impossible to buy or sell a position at the desired price. Market disruptions or volatility can also make it difficult to find a counterparty willing to transact at a reasonable price and sufficient size. Illiquid markets may cause losses, which could be significant. The large size of the positions which the Fund may acquire increases the risk of illiquidity, may make its positions more difficult to liquidate, and may increase the losses incurred while trying to do so. Such large positions also may impact the price of swap agreements on the Emerging Markets ETF shares.

Roundhill Emerging Markets WeeklyPay™ ETF | ACTIVE MANAGEMENT RISK  
Prospectus [Line Items]  
Risk [Text Block]

ACTIVE MANAGEMENT RISK. The Fund is actively-managed and its performance reflects investment decisions that the Adviser and/or Sub-Adviser makes for the Fund. Such judgments about the Fund’s investments may prove to be incorrect. If the investments selected and the strategies employed by the Fund fail to produce the intended results, the Fund could underperform as compared to other funds with similar investment objectives and/or strategies, or could have negative returns.

Roundhill Emerging Markets WeeklyPay™ ETF | ACTIVE MARKET RISK  
Prospectus [Line Items]

ACTIVE MARKET RISK. Although Fund Shares are listed for trading on the Exchange, there can be no assurance that an active trading market for Fund Shares will develop or be maintained. Fund Shares trade on the Exchange at market prices that may be below, at or above the Fund’s net asset value. Securities, including Fund Shares, are subject to market fluctuations and liquidity constraints that may be caused by such factors as economic, political, or regulatory developments, changes in interest rates, and/or perceived trends in securities prices. Fund Shares could decline in value or underperform other investments.

CONCENTRATION RISK. The Fund is susceptible to an increased risk of loss, including losses due to adverse events that affect the Fund’s investments more than the market as a whole, to the extent that the Fund’s investments are concentrated in investments that provide exposure to the Emerging Markets ETF and the industry or group of industries to which it is concentrated.

Roundhill Emerging Markets WeeklyPay™ ETF | COUNTERPARTY RISK

Risk [Text Block]

COUNTERPARTY RISK. Fund transactions involving a counterparty are subject to the risk that the counterparty will not fulfill its obligation to the Fund. Counterparty risk may arise because of the counterparty’s financial condition (i.e., financial difficulties, bankruptcy, or insolvency), market activities and developments, or other reasons, whether foreseen or not. A counterparty’s inability to fulfill its obligation may result in significant financial loss to the Fund. The Fund may be unable to recover its investment from the counterparty or may obtain a limited recovery, and/or recovery may be delayed.

Roundhill Emerging Markets WeeklyPay™ ETF | CURRENT MARKET CONDITIONS RISK  
Prospectus [Line Items]  
Risk [Text Block]

CURRENT MARKET CONDITIONS RISK. Current market conditions risk is the risk that a particular investment, or Fund Shares in general, may fall in value due to current market conditions. As a means to fight inflation, which remains at elevated levels, the Federal Reserve and certain foreign central banks have raised interest rates; however, the Federal Reserve has recently lowered interest rates and may continue to do so. U.S. regulators have proposed several changes to market and issuer regulations which would directly impact the Fund, and any regulatory changes could adversely impact the Fund’s ability to achieve its investment strategies or make certain investments. Recent and potential future bank failures could result in disruption to the broader banking industry or markets generally and reduce confidence in financial institutions and the economy as a whole, which may also heighten market volatility and reduce liquidity. Additionally, challenges in commercial real estate markets, including rising interest rates, declining valuations and increasing vacancies, could have a broader impact on financial markets. The ongoing adversarial political climate in the United States, as well as political and diplomatic events both domestic and abroad, have and may continue to have an adverse impact the U.S. regulatory landscape, markets and investor behavior, which could have a negative impact on the Fund’s investments and operations. The change in administration resulting from the 2024 United States national elections could result in significant impacts to international trade relations, tax and immigration policies, and other aspects of the national and international political and financial landscape, which could affect, among other things, inflation and the securities markets generally. Other unexpected political, regulatory and diplomatic events within the U.S. and abroad may affect investor and consumer confidence and may adversely impact financial markets and the broader economy. For example, ongoing armed conflicts between Russia and Ukraine in Europe and among Israel, Iran, Hamas and other militant groups in the Middle East, have caused and could continue to cause significant market disruptions and volatility within the markets in Russia, Europe, the Middle East and the United States. The hostilities and sanctions resulting from those hostilities have and could continue to have a significant impact on certain Fund investments as well as Fund performance and liquidity. The economies of the United States and its trading partners, as well as the financial markets generally, may be adversely impacted by trade disputes, including the imposition of tariffs, and other matters. For example, the United States has imposed trade barriers and restrictions on China. In addition, the Chinese government is engaged in a longstanding dispute with Taiwan, continually threatening an invasion. If the political climate between the United States and China does not improve or continues to deteriorate, if China were to attempt invading Taiwan, or if other geopolitical conflicts develop or worsen, economies, markets and individual securities may be adversely affected, and the value of the Fund’s assets may go down. A public health crisis and the ensuing policies enacted by governments and central banks may cause significant volatility and uncertainty in global financial markets, negatively impacting global growth prospects. As the COVID-19 global pandemic illustrated, such events may affect certain geographic regions, countries, sectors and industries more significantly than others. Advancements in technology may also adversely impact markets and the overall performance of the Fund. For instance, the economy may be significantly impacted by the advanced development and increased regulation of artificial intelligence. Additionally, cyber security breaches of both government and non-government entities could have negative impacts on infrastructure and the ability of such entities, including the Fund, to operate properly. These events, and any other future events, may adversely affect the prices and liquidity of the Fund’s portfolio investments and could result in disruptions in the trading markets.

Roundhill Emerging Markets WeeklyPay™ ETF | CYBERSECURITY RISK  
Prospectus [Line Items]  
Risk [Text Block]

CYBERSECURITY RISK. Failures or breaches of the electronic systems of the Fund, the Fund’s adviser, sub-adviser, distributor and other service providers, market makers, Authorized Participants or the issuers of securities in which the Fund invests have the ability to cause disruptions, negatively impact the Fund’s business operations and/or potentially result in financial losses to the Fund and its shareholders. While the Fund has established business continuity plans and risk management systems seeking to address system breaches or failures, there are inherent limitations in such plans and systems. Furthermore, the Fund cannot control the cybersecurity plans and systems of the Fund’s other service providers, market makers, Authorized Participants or issuers of securities in which the Fund invests.

Roundhill Emerging Markets WeeklyPay™ ETF | DEBT SECURITIES RISK  
Prospectus [Line Items]  
Risk [Text Block]

DEBT SECURITIES RISK. Investments in debt securities subject the holder to the credit risk of the issuer. Credit risk refers to the possibility that the issuer or other obligor of a security will not be able or willing to make payments of interest and principal when due. Generally, the value of debt securities will change inversely with changes in interest rates. To the extent that interest rates rise, certain underlying obligations may be paid off substantially slower than originally anticipated and the value of those securities may fall sharply. During periods of falling interest rates, the income received by the Fund may decline. If the principal on a debt security is prepaid before expected, the prepayments of principal may have to be reinvested in obligations paying interest at lower rates. Debt securities generally do not trade on a securities exchange making them generally less liquid and more difficult to value than common stock.

Roundhill Emerging Markets WeeklyPay™ ETF | DERIVATIVES RISK  
Prospectus [Line Items]  
Risk [Text Block]

DERIVATIVES RISK. The use of derivative instruments involves risks different from, or possibly greater than, the risks associated with investing directly in securities and other traditional investments. These risks include: (i) the risk that the counterparty to a derivative transaction may not fulfill its contractual obligations; (ii) risk of mispricing or improper valuation; and (iii) the risk that changes in the value of the derivative may not correlate perfectly with the underlying asset. Derivative prices are highly volatile and may fluctuate substantially during a short period of time. Such prices are influenced by numerous factors that affect the markets, including, but not limited to: changing supply and demand relationships; government programs and policies; national and international political and economic events, changes in interest rates, inflation and deflation and changes in supply and demand relationships. Trading derivative instruments involves risks different from, or possibly greater than, the risks associated with investing directly in securities. Derivative contracts ordinarily have leverage inherent in their terms. The use of leverage may cause the Fund to liquidate portfolio positions when it would not be advantageous to do so in order to satisfy its obligations or to meet regulatory or contractual requirements for derivatives. The use of derivatives can magnify potential for gain or loss and, therefore, amplify the effects of market volatility on share price.

Roundhill Emerging Markets WeeklyPay™ ETF | DISTRIBUTION TAX RISK  
Prospectus [Line Items]  
Risk [Text Block]

DISTRIBUTION TAX RISK. The Fund currently expects to make distributions on a weekly basis. Such frequent distributions may expose investors to increased tax liabilities. However, these distributions may exceed the Fund’s income and gains for the Fund’s taxable year. Distributions in excess of the Fund’s current and accumulated earnings and profits will be treated as a return of capital. A return of capital distribution generally will not be taxable but will reduce the shareholder’s cost basis and will result in a higher capital gain or lower capital loss when those Fund Shares on which the distribution was received are sold. Once a Fund shareholder’s cost basis is reduced to zero, further distributions will be treated as capital gain if the Fund shareholder holds Fund Shares as capital assets. Additionally, any capital returned through distributions will be distributed after payment of Fund fees and expenses. Because a portion of the Fund’s distributions may consist of return of capital, the Fund may not be an appropriate investment for investors who do not want their principal investment in the Fund to decrease over time or who do not wish to receive return of capital in a given period. In the event that a shareholder purchases Fund Shares shortly before a distribution by the Fund, the entire distribution may be taxable to the shareholder even though a portion of the distribution effectively represents a return of the purchase price.

Roundhill Emerging Markets WeeklyPay™ ETF | ETF RISK  
Prospectus [Line Items]  
Risk [Text Block]

ETF RISK. The Fund may invest in ETFs. The value of an ETF held by the Fund will fluctuate over time based on fluctuations in the values of the assets held by the ETF, which may be affected by changes in general economic conditions, expectations for future growth and profits, interest rates and the supply and demand for those assets. When the Fund invests in an ETF, it will bear a proportionate share of the ETF’s expenses. Brokerage, tax and other expenses may negatively impact the performance of the ETF and, in turn, the value of the Fund Shares. An ETF that tracks an index may not exactly match the performance of the index due to cash drag, differences between the portfolio of the ETF and the components of the index, expenses and other factors.

Roundhill Emerging Markets WeeklyPay™ ETF | INFLATION RISK  
Prospectus [Line Items]  
Risk [Text Block]

INFLATION RISK. Inflation risk is the risk that the value of assets or income from investments will be less in the future as inflation decreases the value of money. As inflation increases, the present value of the Fund’s assets and distributions may decline. This risk is more prevalent with respect to fixed income securities held by the Fund.

Roundhill Emerging Markets WeeklyPay™ ETF | Interest Rate Risk [Member]  
Prospectus [Line Items]  
Risk [Text Block]

INTEREST RATE RISK. Interest rate risk is the risk that the value of the debt securities in the Fund’s portfolio will decline because of rising market interest rates. Interest rate risk is generally lower for shorter term debt securities and higher for longer-term debt securities. Duration is a reasonably accurate measure of a debt security’s price sensitivity to changes in interest rates and a common measure of interest rate risk. Duration measures a debt security’s expected life on a present value basis, taking into account the debt security’s yield, interest payments and final maturity. In general, duration represents the expected percentage change in the value of a security for an immediate 1% change in interest rates. For example, the price of a debt security with a three-year duration would be expected to drop by approximately 3% in response to a 1% increase in interest rates. Therefore, prices of debt securities with shorter durations tend to be less sensitive to interest rate changes than debt securities with longer durations. As the value of a debt security changes over time, so will its duration.

Roundhill Emerging Markets WeeklyPay™ ETF | LEGISLATION AND LITIGATION RISK  
Prospectus [Line Items]  
Risk [Text Block]

LEGISLATION AND LITIGATION RISK. Legislation or litigation that affects the value of assets or securities held by the Fund may reduce the value of the Fund. From time to time, various legislative initiatives are proposed that may have a negative impact on certain assets or securities in which the Fund invests. In addition, litigation regarding any of the assets or securities owned by the Fund may negatively impact the value of the Shares. Such legislation or litigation may cause the Fund to lose value or may result in higher portfolio turnover if the Adviser determines to sell such a holding.

Roundhill Emerging Markets WeeklyPay™ ETF | LEVERAGE RISK  
Prospectus [Line Items]  
Risk [Text Block]

LEVERAGE RISK. The Fund obtains investment exposure in excess of its net assets by utilizing leverage and may lose more money in market conditions that are adverse to its investment objectives than a fund that does not utilize leverage. An investment in the Fund is exposed to the risk that a decline in the weekly performance of shares of the Emerging Markets ETF will be magnified. This means that an investment in the Fund will be reduced by an amount equal to 1.2% for every 1% weekly decline in the market value of the Emerging Markets ETF shares, not including the costs of financing leverage and other operating expenses, which would further reduce its value. The Fund could theoretically lose an amount greater than its net assets in the event the market value of the Emerging Markets ETF shares decline more than 83.33% over a calendar week. Leverage will also have the effect of magnifying any differences in the Fund’s correlation with the Emerging Markets ETF shares.

Roundhill Emerging Markets WeeklyPay™ ETF | MONEY MARKET INSTRUMENTS RISK  
Prospectus [Line Items]  
Risk [Text Block]

MONEY MARKET INSTRUMENTS RISK. The value of money market instruments may be affected by changing interest rates and by changes in the credit ratings of the investments. If a significant amount of the Fund’s assets are invested in money market instruments, it will be more difficult for the Fund to achieve its investment objectives. An investment in a money market fund is not insured or guaranteed by the FDIC or any other government agency. It is possible to lose money by investing in a money market fund.

Roundhill Emerging Markets WeeklyPay™ ETF | OPERATIONAL RISK  
Prospectus [Line Items]  
Risk [Text Block]

OPERATIONAL RISK. The Fund is subject to risks arising from various operational factors, including, but not limited to, human error, processing and communication errors, errors of the Fund’s service providers, counterparties or other third-parties, failed or inadequate processes and technology or systems failures. The Fund relies on third-parties for a range of services, including custody. Any delay or failure relating to engaging or maintaining such service providers may affect the Fund’s ability to meet its investment objectives. Although the Fund and the Adviser seek to reduce these operational risks through controls and procedures, there is no way to completely protect against such risks.

Roundhill Emerging Markets WeeklyPay™ ETF | SPECIAL TAX RISK  
Prospectus [Line Items]  
Risk [Text Block]

SPECIAL TAX RISK. The Fund intends to qualify annually and to elect to be treated as a regulated investment company under the Internal Revenue Code of 1986, as amended (the “Code”). To qualify for the favorable U.S. federal income tax treatment generally accorded to regulated investment companies, the Fund must, among other things, (i) derive in each taxable year at least 90% of its gross income from dividends, interest, payments with respect to securities loans and gains from the sale or other disposition of stock, securities or foreign currencies or other income derived with respect to its business of investing in such stock, securities or currencies, or net income derived from interests in certain publicly traded partnerships; (ii) diversify its holdings so that, at the end of each quarter of the taxable year, (a) at least 50% of the market value of the Fund’s assets is represented by cash and cash items (including receivables), U.S. government securities, the securities of other regulated investment companies and other securities, with such other securities of any one issuer generally limited for the purposes of this calculation to an amount not greater than 5% of the value of the Fund’s total assets and not greater than 10% of the outstanding voting securities of such issuer, and (b) not more than 25% of the value of its total assets is invested in the securities (other than U.S. government securities or the securities of other regulated investment companies) of any one issuer, or two or more issuers which the Fund controls which are engaged in the same, similar or related trades or businesses, or the securities of one or more of certain publicly traded partnerships; and (iii) distribute at least 90% of its investment company taxable income (which includes, among other items, dividends, interest and net short-term capital gains in excess of net long-term capital losses) and at least 90% of its net tax-exempt interest income each taxable year. There are certain exceptions for failure to qualify if the failure is for reasonable cause or is de minimis, and certain corrective action is taken and certain tax payments are made by the Fund.

 

The authority with regard to swaps entered into by regulated investment companies is unclear both as to the qualification under the income test and the identification of the issuer under the diversification test. The Fund intends to take the position that because the swaps held by the Fund reference securities that the income on the swaps are “other income” from the Fund’s business of investing in stocks and securities. In addition, the Fund intends to manage its investments in the swaps so that neither the exposure to issuer of the referenced security nor the exposure to any one counterparty of the swaps will exceed 25% of the gross value of the Fund’s portfolio at the end of any quarter.

 

If the Fund were to fail to meet the qualifying income test or asset diversification test and fail to qualify as a RIC, it would be taxed in the same manner as an ordinary corporation, and distributions to its shareholders would not be deductible by the Fund in computing its taxable income, which would adversely affect the Fund’s performance.

Roundhill Emerging Markets WeeklyPay™ ETF | STRUCTURAL ETF RISKS  
Prospectus [Line Items]  
Risk [Text Block]

STRUCTURAL ETF RISKS. The Fund is an ETF. Accordingly, it is subject to certain risks associated with its unique structure.

 

Market Participants Risk. Only an Authorized Participant may engage in creation or redemption transactions directly with the Fund, and none of those Authorized Participants is obligated to engage in creation and/or redemption transactions. The Fund has a limited number of institutions that may act as Authorized Participants on an agency basis (i.e., on behalf of other market participants). To the extent that Authorized Participants exit the business or are unable to proceed with creation or redemption orders with respect to the Fund and no other Authorized Participant is able to step forward to create or redeem, Fund Shares may be more likely to trade at a premium or discount to NAV and possibly face trading halts or delisting. The Fund may also rely on a small number of third-party market makers to provide a market for the purchase and sale of Fund Shares but such market makers are under no obligation to do so. Decisions by Authorized Participants or market makers to reduce their role or step away from these activities in times of market stress could inhibit the effectiveness of the arbitrage process in maintaining the relationship between the underlying values of the Fund’s portfolio securities and the Fund’s market price. Any trading halt or other problem relating to the trading activity of these market makers or any issues disrupting the Authorized Participants’ ability to proceed with creation and/or redemption orders could result in a dramatic change in the spread between the Fund’s net asset value and the price at which Fund Shares are trading on the Exchange, which could result in a decrease in value of Fund Shares. This reduced effectiveness could result in Fund Shares trading at a premium or discount to net asset value and also in greater than normal intraday bid-ask spreads Fund Shares.

 

Cash Transactions Risk. The Fund currently expects to effect a significant portion of its creations and redemptions for cash, rather than in-kind securities. Paying redemption proceeds in cash rather than through in-kind delivery of portfolio securities may require the Fund to dispose of or sell portfolio securities or other assets at an inopportune time to obtain the cash needed to meet redemption orders. This may cause the Fund to sell a security and recognize a capital gain or loss that might not have been incurred if it had made a redemption in-kind. As a result, the Fund may pay out higher or lower annual capital gains distributions than ETFs that redeem in-kind. The use of cash creations and redemptions may also cause the Fund’s Shares to trade in the market at greater bid-ask spreads or greater premiums or discounts to the Fund’s NAV. Furthermore, the Fund may not be able to execute cash transactions for creation and redemption purposes at the same price used to determine the Fund’s NAV. To the extent that the maximum additional charge for creation or redemption transactions is insufficient to cover the execution shortfall, the Fund’s performance could be negatively impacted.

 

Costs of Buying and Selling Fund Shares. Due to the costs of buying or selling Fund Shares, including brokerage commissions imposed by brokers and bid/ask spreads, frequent trading of Fund Shares may significantly reduce investment results and an investment in Fund Shares may not be advisable for investors who anticipate regularly making small investments.

 

Premium/Discount Risk. As with all ETFs, Fund Shares may be bought and sold in the secondary market at market prices. The trading prices of Fund Shares in the secondary market may differ from the Fund’s daily net asset value per share and there may be times when the market price of the shares is more than the net asset value per share (premium) or less than the net asset value per share (discount). If a shareholder purchases Fund Shares at a time when the market price is at a premium to the net asset value or sells Fund Shares at a time when the market price is at a discount to the net asset value, the shareholder may pay more for, or receive less than, the underlying value of the Fund Shares, respectively. This risk is heightened in times of market volatility or periods of steep market declines.

 

Trading Risks. Although Fund Shares are listed for trading on the Exchange and may be traded on U.S. exchanges other than the Exchange, there can be no assurance that Fund Shares will trade with any volume, or at all, on any stock exchange. In stressed market conditions, the liquidity of Fund Shares may begin to mirror the liquidity of the Fund’s underlying portfolio holdings, which can be significantly less liquid than Fund Shares. Trading in Fund Shares on the Exchange may be halted due to market conditions or for reasons that, in the view of the Exchange, make trading in Fund Shares inadvisable. In addition, trading in Fund Shares on the Exchange is subject to trading halts caused by extraordinary market volatility pursuant to the Exchange’s “circuit breaker” rules. There can be no assurance that the requirements of the Exchange necessary to maintain the listing of the Fund will continue to be met or will remain unchanged.

Roundhill Emerging Markets WeeklyPay™ ETF | U.S. GOVERNMENT SECURITIES RISK  
Prospectus [Line Items]  
Risk [Text Block]

U.S. GOVERNMENT SECURITIES RISK. U.S. government securities are subject to interest rate risk but generally do not involve the credit risks associated with investments in other types of debt securities. As a result, the yields available from U.S. government securities are generally lower than the yields available from other debt securities. U.S. government securities are guaranteed only as to the timely payment of interest and the payment of principal when held to maturity.

Roundhill Emerging Markets WeeklyPay™ ETF | VALUATION RISK  
Prospectus [Line Items]  
Risk [Text Block]

VALUATION RISK. The Fund may hold securities or other assets that may be valued on the basis of factors other than market quotations. This may occur because the asset or security does not trade on a centralized exchange, or in times of market turmoil or reduced liquidity. There are multiple methods that can be used to value a portfolio holding when market quotations are not readily available. The value established for any portfolio holding at a point in time might differ from what would be produced using a different methodology or if it had been priced using market quotations. Portfolio holdings that are valued using techniques other than market quotations, including “fair valued” assets or securities, may be subject to greater fluctuation in their valuations from one day to the next than if market quotations were used. In addition, there is no assurance that the Fund could sell or close out a portfolio position for the value established for it at any time, and it is possible that the Fund would incur a loss because a portfolio position is sold or closed out at a discount to the valuation established by the Fund at that time. The Fund’s ability to value investments may be impacted by technological issues or errors by pricing services or other third-party service providers.

Roundhill Emerging Markets WeeklyPay™ ETF | EQUITY SECURITIES RISK  
Prospectus [Line Items]  
Risk [Text Block]

EQUITY SECURITIES RISK. Equity securities are subject to changes in value, and their values may be more volatile than those of other asset classes. Equity securities prices fluctuate for several reasons, including changes in investors’ perceptions of the financial condition of an issuer or the general condition of the relevant equity market, such as market volatility, or when political or economic events affecting an issuer occur. Common stock prices may be particularly sensitive to rising interest rates, as the cost of capital rises and borrowing costs increase. Common stocks generally subject their holders to more risks than preferred stocks and debt securities because common stockholders’ claims are subordinated to those of holders of preferred stocks and debt securities upon the bankruptcy of the issuer.

Roundhill Emerging Markets WeeklyPay™ ETF | SWAP AGREEMENTS RISK  
Prospectus [Line Items]  
Risk [Text Block]

SWAP AGREEMENTS RISK. The Fund will utilize swap agreements to derive its exposure to shares of the Emerging Markets ETF. Swap agreements may involve greater risks than direct investment in securities as they may be leveraged and are subject to credit risk, counterparty risk and valuation risk. A swap agreement could result in losses if the underlying reference or asset does not perform as anticipated. In addition, many swaps trade over-the-counter and may be considered illiquid. It may not be possible for the Fund to liquidate a swap position at an advantageous time or price, which may result in significant losses.

Roundhill Emerging Markets WeeklyPay™ ETF | NEW FUND RISK  
Prospectus [Line Items]  
Risk [Text Block]

NEW FUND RISK. The Fund is a recently organized investment company with a limited operating history. As a result, prospective investors have a limited track record or history on which to base their investment decision.

Roundhill Emerging Markets WeeklyPay™ ETF | REGULATED INVESTMENT COMPANY TAX RISKS  
Prospectus [Line Items]  
Risk [Text Block]

REGULATED INVESTMENT COMPANY TAX RISKS. The Fund intends to qualify annually and to elect to be treated as a regulated investment company under the Internal Revenue Code of 1986, as amended (the “Code”). To qualify for the favorable U.S. federal income tax treatment generally accorded to regulated investment companies, the Fund must, among other things, (i) derive in each taxable year at least 90% of its gross income from dividends, interest, payments with respect to securities loans and gains from the sale or other disposition of stock, securities or foreign currencies or other income derived with respect to its business of investing in such stock, securities or currencies, or net income derived from interests in certain publicly traded partnerships; (ii) diversify its holdings so that, at the end of each quarter of the taxable year, (a) at least 50% of the market value of the Fund’s assets is represented by cash and cash items (including receivables), U.S. government securities, the securities of other regulated investment companies and other securities, with such other securities of any one issuer generally limited for the purposes of this calculation to an amount not greater than 5% of the value of the Fund’s total assets and not greater than 10% of the outstanding voting securities of such issuer, and (b) not more than 25% of the value of its total assets is invested in the securities (other than U.S. government securities or the securities of other regulated investment companies) of any one issuer, or two or more issuers which the Fund controls which are engaged in the same, similar or related trades or businesses, or the securities of one or more of certain publicly traded partnerships; and (iii) distribute at least 90% of its investment company taxable income (which includes, among other items, dividends, interest and net short-term capital gains in excess of net long-term capital losses) and at least 90% of its net tax-exempt interest income each taxable year. There are certain exceptions for failure to qualify if the failure is for reasonable cause or is de minimis, and certain corrective action is taken and certain tax payments are made by the Fund.

 

If the Fund were to fail to meet the qualifying income test or asset diversification test and fail to qualify as a RIC, it would be taxed in the same manner as an ordinary corporation, and distributions to its shareholders would not be deductible by the Fund in computing its taxable income, which would adversely affect the Fund’s performance.

Roundhill Emerging Markets WeeklyPay™ ETF | LARGE SHAREHOLDER RISK  
Prospectus [Line Items]  
Risk [Text Block]

LARGE SHAREHOLDER RISK. Certain shareholders, including affiliated funds advised by the Adviser, may from time to time own a significant portion of the Fund’s shares. In addition, a third-party investor, the Adviser or an affiliate of the Adviser (“Affiliate”), an authorized participant, a market maker, or another entity may invest in the Fund and hold its investment for a limited period solely to facilitate the commencement of the Fund or to help the Fund achieve a specified size or scale. There can be no assurance that any large shareholder will not redeem its investment, that the size of the Fund will be maintained at such levels, or that the Fund will continue to meet applicable listing requirements. Redemptions by large shareholders could have a significant negative impact on the Fund. In addition, transactions by large shareholders may account for a large percentage of the trading volume on the Fund’s listing exchange and may, therefore, have a material upward or downward effect on the market price of the shares.

 

To the extent that a significant percentage of the Fund’s shares are owned or controlled by a small number of account shareholders (or a single account shareholder), including funds or accounts over which the Adviser or an Affiliate has investment discretion, the Fund is subject to the risk that those shareholders may purchase or redeem Fund shares in significant amounts rapidly or unexpectedly, including as a result of an asset allocation decision made by the Adviser or an Affiliate. This may adversely affect the Fund’s performance if the Adviser is forced to sell portfolio securities or invest cash when it would not otherwise choose to do so. Redemptions of a large number of shares may affect the liquidity of the Fund’s portfolio, increase the Fund’s transaction costs, and accelerate the realization of taxable income and/or gains. In addition, a large redemption could result in the Fund’s current expenses being allocated over a smaller asset base, leading to an increase in the Fund’s gross expense ratio. Large purchases of the Fund’s shares may also adversely affect the Fund’s performance to the extent that the Fund is delayed in investing new cash or otherwise maintains a larger cash position than it ordinarily would, particularly if the Fund accepts cash for an order for the purchase of creation units of the Fund’s shares.

Roundhill Emerging Markets WeeklyPay™ ETF | EMERGING MARKETS ETF INVESTING RISKS  
Prospectus [Line Items]  
Risk [Text Block]

EMERGING MARKETS ETF INVESTING RISKS. The Fund will have significant exposure to the Emerging Markets ETF through its investments in shares of the Emerging Markets ETF and swap agreements that utilize the Emerging Markets ETF as the reference asset. Accordingly, the Fund will subject to the risks of the Emerging Markets ETF, set forth below. In addition to these risks, the Emerging Markets ETF is also subject to the following risks to which the Fund is also subject, which are described within the section entitled “Principal Risks”: Market Risk, Asset Class Risk, Concentration Risk, Current Market Conditions Risk, Cybersecurity Risk, Equity Securities Risk, Operational Risk, Structural ETF Risk and Valuation Risk.

 

CURRENCY RISK. Because the Emerging Markets ETF’s NAV is determined in U.S. dollars, the NAV could decline if the currency of a non-U.S. market in which the Emerging Markets ETF invests depreciates against the U.S. dollar or if there are delays or limits on the repatriation of foreign currency. Currency exchange rates can be very volatile and can change quickly and unpredictably. As a result, the Emerging Markets ETF’s NAV may change quickly and without warning. In addition, the Emerging Markets ETF may incur costs in connection with conversions between U.S. dollars and foreign currencies.

 

CUSTODY RISK. Less developed securities markets are more likely to experience problems with the clearing and settlement of trades, as well as the custody of securities and other assets by local banks, agents and depositories. These issues may have an adverse impact on the Emerging Markets ETF, including losses or delays in payments, delivery or recovery of money or other assets.

 

INDEX-RELATED RISK. The Emerging Markets ETF Index Provider may rely on various sources of information to assess the criteria of components of the Emerging Markets ETF Index, including information that may be based on assumptions and estimates. Neither the Emerging Markets ETF nor its investment adviser offer assurances that the Emerging Markets ETF Index Provider’s methodology or sources of information will provide an accurate assessment of included components or will result in the Emerging Markets ETF meeting its investment objective. Errors in index data, index computations or the construction of the Emerging Markets ETF Index in accordance with its methodology may occur, and the Emerging Markets ETF Index Provider may not identify or correct them promptly or at all, which may have an adverse impact on the Emerging Markets ETF and its shareholders. Unusual market conditions or other unforeseen circumstances (such as natural disasters, political unrest or war) may impact the Emerging Markets ETF Index Provider or a third-party data provider and could cause the Emerging Markets ETF Index Provider to postpone a scheduled rebalance. This could cause the Emerging Markets ETF Index to vary from its normal or expected composition.

 

INDIRECT INVESTMENT RISK. The Emerging Markets ETF is not affiliated with the Trust, the Fund, the Adviser, the Sub-Adviser or any affiliates thereof and is not involved with this offering in any way, and has no obligation to consider the Fund in taking any actions that might affect the value of the Fund. The Trust, the Fund, the Adviser, the Sub-Adviser or any affiliate are not responsible for the performance of the Emerging Markets ETF and make no representation as to the performance of the Emerging Markets ETF. Investing in the Fund is not equivalent to investing in the Emerging Markets ETF Fund shareholders will not have voting rights or rights to receive dividends or other distributions or any other rights with respect to the Emerging Markets ETF.

 

LARGE CAPITALIZATION COMPANIES RISK. Large capitalization companies may be less able than smaller capitalization companies to adapt to changing market conditions. Large capitalization companies may be more mature and subject to more limited growth potential compared with smaller capitalization companies. During different market cycles, the performance of large capitalization companies has trailed the overall performance of the broader securities markets.

 

MID-CAPITALIZATION COMPANIES RISK. Compared to large capitalization companies, mid-capitalization companies may be less stable and more susceptible to adverse developments. The securities of mid-capitalization companies may be more volatile and less liquid than those of large-capitalization companies. As a result, the Emerging Markets ETF’s share price may be more volatile than that of a fund with a greater investment in large-capitalization stocks.

 

NON-U.S. SECURITIES RISK. Securities issued by non-U.S. issuers (including depositary receipts) are subject to different legal, regulatory, political, economic, and market risks than securities issued by U.S. issuers. These risks include greater market volatility, less market liquidity, higher transaction costs, expropriation, confiscatory taxation, adverse changes in foreign investment or currency control regulations, restrictions on the repatriation of capital, and political instability. Non-U.S. issuers may be subject to different accounting, audit and financial reporting standards than U.S. issuers, and there may be less publicly available information about non-U.S. issuers. Foreign market trading hours, different clearing and settlement procedures, and holiday schedules may limit the Emerging Markets ETF’s ability to engage in portfolio transactions. To the extent that investments are made in a limited number of countries, events in those countries will have a more significant impact on the Emerging Markets ETF.

 

RISK OF INVESTING IN CHINA. Investments in Chinese securities, including certain Hong Kong-listed and U.S.-listed securities, subject the Emerging Markets ETF to risks specific to China. China may be subject to considerable degrees of economic, political and social instability. China is an emerging market and demonstrates significantly higher volatility from time to time in comparison to developed markets. Over the last few decades, the Chinese government has undertaken reform of economic and market practices and has expanded the sphere of private ownership of property in China. However, Chinese markets generally continue to experience inefficiency, volatility and pricing anomalies resulting from governmental influence, a lack of publicly available information and/or political and social instability. Chinese companies are also subject to the risk that Chinese authorities can intervene in their operations and structure. Internal social unrest or confrontations with neighboring countries, including military conflicts in response to such events, may also disrupt economic development in China and result in a greater risk of currency fluctuations, currency non-convertibility, interest rate fluctuations and higher rates of inflation. China has experienced security concerns, such as terrorism and strained international relations. Additionally, China is alleged to have participated in state-sponsored cyberattacks against foreign companies and foreign governments. Actual and threatened responses to such activity and strained international relations, including purchasing restrictions, sanctions, tariffs or cyberattacks on the Chinese government or Chinese companies, may impact China’s economy and Chinese issuers of securities in which the Emerging Markets ETF invests. Incidents involving China’s or the region’s security may cause uncertainty in Chinese markets and may adversely affect the Chinese economy and the Emerging Markets ETF’s investments. Export growth continues to be a major driver of China’s rapid economic growth. Reduction in spending on Chinese products and services, supply chain diversification, institution of additional tariffs or other trade barriers (including as a result of heightened trade tensions or a trade war between China and the U.S. or in response to actual or alleged Chinese cyber activity) or a downturn in any of the economies of China’s key trading partners may have an adverse impact on the Chinese economy. The Emerging Markets ETF Index may include companies that are subject to economic or trade restrictions (but not investment restrictions) imposed by the U.S. or other governments due to national security, human rights or other concerns of such government. So long as these restrictions do not include restrictions on investments, the Emerging Markets ETF is generally expected to invest in such companies, consistent with its objective to track the performance of the Emerging Markets ETF Index.

 

Chinese companies, including Chinese companies that are listed on U.S. exchanges, are not subject to the same degree of regulatory requirements, accounting standards or auditor oversight as companies in more developed countries. As a result, information about Chinese securities in which the Emerging Markets ETF invests may be less reliable or complete. Chinese companies with securities listed on U.S. exchanges may be delisted if they do not meet U.S. accounting standards and auditor oversight requirements, which would significantly decrease the liquidity and value of the securities. There may be significant obstacles to obtaining information necessary for investigations into or litigation against Chinese companies, and investors may have limited legal remedies. The Emerging Markets ETF does not select investments based on investor protection considerations.

 

RISK OF INVESTING IN EMERGING MARKETS. Investments in emerging market issuers may be subject to a greater risk of loss than investments in issuers located or operating in more developed markets. Emerging markets may be more likely to experience inflation, social instability, political turmoil or rapid changes in economic conditions than more developed markets. Companies in many emerging markets are not subject to the same degree of regulatory requirements, accounting standards or auditor oversight as companies in more developed countries, and as a result, information about the securities in which the Emerging Markets ETF invests may be less reliable or complete. Emerging markets often have less reliable securities valuations and greater risk associated with custody of securities than developed markets. There may be significant obstacles to obtaining information necessary for investigations into or litigation against companies and shareholders may have limited legal remedies. The Emerging Markets ETF does not select investments based on investor protection considerations.

 

RISK OF INVESTING IN RUSSIA. Investing in Russian securities involves significant risks, including legal, regulatory, currency and economic risks that are specific to Russia. In addition, investing in Russian securities involves risks associated with the settlement of portfolio transactions and loss of the Emerging Markets ETF’s ownership rights in its portfolio securities as a result of the system of share registration and custody in Russia. Governments, including the U.S., the U.K., the E.U., and many other countries have imposed economic sanctions on certain Russian individuals and Russian corporate and banking entities, and jurisdictions may also institute broader sanctions on Russia. Russia has issued a number of countersanctions, some of which restrict the distribution of profits by limited liability companies (e.g., dividends), and prohibit Russian persons from entering into transactions with designated persons from “unfriendly states” as well as the export of raw materials or other products from Russia to certain sanctioned persons.

 

Russia launched a large-scale invasion of Ukraine on February 24, 2022. The extent and duration of the military action, resulting sanctions and resulting future market disruptions, including declines in its stock markets and the value of the ruble against the U.S. dollar, are impossible to predict, but could be significant. Disruptions caused by Russian military action or other actions (including cyberattacks and espionage) or resulting actual and threatened responses to such activity, including purchasing and financing restrictions, boycotts or changes in consumer or purchaser preferences, sanctions, import and export restrictions, tariffs or cyberattacks on the Russian government, Russian companies, or Russian individuals, including politicians, may impact Russia’s economy and Russian companies in which the Emerging Markets ETF invests. Actual and threatened responses to Russian military action may also impact the markets for certain Russian commodities, such as oil and natural gas, as well as other sectors of the Russian economy, and are likely to have collateral impacts on such sectors globally. Russian companies may be unable to pay dividends and, if they pay dividends, the Emerging Markets ETF may be unable to receive them. As a result of sanctions, the Emerging Markets ETF is currently restricted from trading in Russian securities, including those in its portfolio, and the Emerging Markets ETF Index has removed Russian securities. It is unknown when, or if, sanctions may be lifted or the Emerging Markets ETF’s ability to trade in Russian securities will resume.

 

RISK OF INVESTING IN SAUDI ARABIA. Investing in Saudi Arabian issuers subjects the Emerging Markets ETF to legal, regulatory, political, currency, security, and economic risks that are specific to Saudi Arabia. The economy of Saudi Arabia is dominated by petroleum exports. A sustained decrease in petroleum prices could have a negative impact on all aspects of the economy. Investments in the securities of Saudi Arabian issuers involve risks not typically associated with investments in securities of issuers in more developed countries, which may negatively affect the value of the Emerging Markets ETF’s investments. Such heightened risks may include, among others, the expropriation and/or nationalization of assets, restrictions on and government intervention in international trade, confiscatory taxation, political instability, including authoritarian and/or military involvement in governmental decision-making, armed conflict, crime and instability as a result of religious, ethnic and/or socioeconomic unrest. Instability in the Middle East region could adversely impact the economy of Saudi Arabia, and there is no assurance of political stability in Saudi Arabia.

 

The ability of foreign investors to invest in the securities of Saudi Arabian companies could be restricted by the Saudi Arabian government at any time, and unforeseen risks could materialize with respect to foreign ownership of such securities. There are a number of ways to conduct transactions in equity securities in the Saudi Arabian market. The Emerging Markets ETF generally expects to transact in a manner so that it is not limited by Saudi Arabian regulations to a single broker. However, there may be a limited number of brokers who can provide services to the Emerging Markets ETF, which may have an adverse impact on the prices, quantity or timing of the Emerging Markets ETF transactions.

NON-DIVERSIFICATION RISK. As a “non-diversified” fund, the Fund may hold a smaller number of portfolio securities than many other funds. To the extent the Fund invests in a relatively small number of issuers, a decline in the market value of a particular security held by the Fund may affect its value more than if it invested in a larger number of issuers. The value of the Fund Shares may be more volatile than the values of shares of more diversified funds.

Roundhill Developed Markets WeeklyPay™ ETF | MARKET RISK  
Prospectus [Line Items]  
Risk [Text Block]

MARKET RISK. Market risk is the risk that a particular investment, or Fund Shares in general, may fall in value. Securities are subject to market fluctuations caused by real or perceived adverse economic, political, and regulatory factors or market developments, changes in interest rates, disruptions to trade, impositions of tariffs and perceived trends in securities prices. Fund Shares could decline in value or underperform other investments. In addition, local, regional or global events such as war, acts of terrorism, market manipulation, government defaults, government shutdowns, regulatory actions, political changes, diplomatic developments, the imposition of sanctions and other similar measures, spread of infectious diseases or other public health issues, recessions, natural disasters, or other events could have a significant negative impact on the Fund and its investments. Any of such circumstances could have a materially negative impact on the value of Fund Shares, the liquidity of an investment, and may result in increased market volatility. During any such events, Fund Shares may trade at increased premiums or discounts to their net asset value, the bid/ask spread on Fund Shares may widen and the returns on investment may fluctuate.

Roundhill Developed Markets WeeklyPay™ ETF | LIQUIDITY RISK  
Prospectus [Line Items]  
Risk [Text Block]

LIQUIDITY RISK. The market for swap agreements that reference the Developed Markets ETF shares may be subject to periods of illiquidity. During such times it may be difficult or impossible to buy or sell a position at the desired price. Market disruptions or volatility can also make it difficult to find a counterparty willing to transact at a reasonable price and sufficient size. Illiquid markets may cause losses, which could be significant. The large size of the positions which the Fund may acquire increases the risk of illiquidity, may make its positions more difficult to liquidate, and may increase the losses incurred while trying to do so. Such large positions also may impact the price of swap agreements on the Developed Markets ETF shares.

Roundhill Developed Markets WeeklyPay™ ETF | ACTIVE MANAGEMENT RISK

ACTIVE MANAGEMENT RISK. The Fund is actively-managed and its performance reflects investment decisions that the Adviser and/or Sub-Adviser makes for the Fund. Such judgments about the Fund’s investments may prove to be incorrect. If the investments selected and the strategies employed by the Fund fail to produce the intended results, the Fund could underperform as compared to other funds with similar investment objectives and/or strategies, or could have negative returns.

Roundhill Developed Markets WeeklyPay™ ETF | ACTIVE MARKET RISK

ACTIVE MARKET RISK. Although Fund Shares are listed for trading on the Exchange, there can be no assurance that an active trading market for Fund Shares will develop or be maintained. Fund Shares trade on the Exchange at market prices that may be below, at or above the Fund’s net asset value. Securities, including Fund Shares, are subject to market fluctuations and liquidity constraints that may be caused by such factors as economic, political, or regulatory developments, changes in interest rates, and/or perceived trends in securities prices. Fund Shares could decline in value or underperform other investments.

CONCENTRATION RISK. The Fund is susceptible to an increased risk of loss, including losses due to adverse events that affect the Fund’s investments more than the market as a whole, to the extent that the Fund’s investments are concentrated in investments that provide exposure to the Developed Markets ETF and the industry or group of industries to which it is concentrated.

Roundhill Developed Markets WeeklyPay™ ETF | COUNTERPARTY RISK

COUNTERPARTY RISK. Fund transactions involving a counterparty are subject to the risk that the counterparty will not fulfill its obligation to the Fund. Counterparty risk may arise because of the counterparty’s financial condition (i.e., financial difficulties, bankruptcy, or insolvency), market activities and developments, or other reasons, whether foreseen or not. A counterparty’s inability to fulfill its obligation may result in significant financial loss to the Fund. The Fund may be unable to recover its investment from the counterparty or may obtain a limited recovery, and/or recovery may be delayed.

Roundhill Developed Markets WeeklyPay™ ETF | CURRENT MARKET CONDITIONS RISK  
Prospectus [Line Items]  
Risk [Text Block]

CURRENT MARKET CONDITIONS RISK. Current market conditions risk is the risk that a particular investment, or Fund Shares in general, may fall in value due to current market conditions. As a means to fight inflation, which remains at elevated levels, the Federal Reserve and certain foreign central banks have raised interest rates; however, the Federal Reserve has recently lowered interest rates and may continue to do so. U.S. regulators have proposed several changes to market and issuer regulations which would directly impact the Fund, and any regulatory changes could adversely impact the Fund’s ability to achieve its investment strategies or make certain investments. Recent and potential future bank failures could result in disruption to the broader banking industry or markets generally and reduce confidence in financial institutions and the economy as a whole, which may also heighten market volatility and reduce liquidity. Additionally, challenges in commercial real estate markets, including rising interest rates, declining valuations and increasing vacancies, could have a broader impact on financial markets. The ongoing adversarial political climate in the United States, as well as political and diplomatic events both domestic and abroad, have and may continue to have an adverse impact the U.S. regulatory landscape, markets and investor behavior, which could have a negative impact on the Fund’s investments and operations. The change in administration resulting from the 2024 United States national elections could result in significant impacts to international trade relations, tax and immigration policies, and other aspects of the national and international political and financial landscape, which could affect, among other things, inflation and the securities markets generally. Other unexpected political, regulatory and diplomatic events within the U.S. and abroad may affect investor and consumer confidence and may adversely impact financial markets and the broader economy. For example, ongoing armed conflicts between Russia and Ukraine in Europe and among Israel, Iran, Hamas and other militant groups in the Middle East, have caused and could continue to cause significant market disruptions and volatility within the markets in Russia, Europe, the Middle East and the United States. The hostilities and sanctions resulting from those hostilities have and could continue to have a significant impact on certain Fund investments as well as Fund performance and liquidity. The economies of the United States and its trading partners, as well as the financial markets generally, may be adversely impacted by trade disputes, including the imposition of tariffs, and other matters. For example, the United States has imposed trade barriers and restrictions on China. In addition, the Chinese government is engaged in a longstanding dispute with Taiwan, continually threatening an invasion. If the political climate between the United States and China does not improve or continues to deteriorate, if China were to attempt invading Taiwan, or if other geopolitical conflicts develop or worsen, economies, markets and individual securities may be adversely affected, and the value of the Fund’s assets may go down. A public health crisis and the ensuing policies enacted by governments and central banks may cause significant volatility and uncertainty in global financial markets, negatively impacting global growth prospects. As the COVID-19 global pandemic illustrated, such events may affect certain geographic regions, countries, sectors and industries more significantly than others. Advancements in technology may also adversely impact markets and the overall performance of the Fund. For instance, the economy may be significantly impacted by the advanced development and increased regulation of artificial intelligence. Additionally, cyber security breaches of both government and non-government entities could have negative impacts on infrastructure and the ability of such entities, including the Fund, to operate properly. These events, and any other future events, may adversely affect the prices and liquidity of the Fund’s portfolio investments and could result in disruptions in the trading markets.

Roundhill Developed Markets WeeklyPay™ ETF | CYBERSECURITY RISK

Risk [Text Block]

CYBERSECURITY RISK. Failures or breaches of the electronic systems of the Fund, the Fund’s adviser, sub-adviser, distributor and other service providers, market makers, Authorized Participants or the issuers of securities in which the Fund invests have the ability to cause disruptions, negatively impact the Fund’s business operations and/or potentially result in financial losses to the Fund and its shareholders. While the Fund has established business continuity plans and risk management systems seeking to address system breaches or failures, there are inherent limitations in such plans and systems. Furthermore, the Fund cannot control the cybersecurity plans and systems of the Fund’s other service providers, market makers, Authorized Participants or issuers of securities in which the Fund invests.

Roundhill Developed Markets WeeklyPay™ ETF | DEBT SECURITIES RISK  
Prospectus [Line Items]  
Risk [Text Block]

DEBT SECURITIES RISK. Investments in debt securities subject the holder to the credit risk of the issuer. Credit risk refers to the possibility that the issuer or other obligor of a security will not be able or willing to make payments of interest and principal when due. Generally, the value of debt securities will change inversely with changes in interest rates. To the extent that interest rates rise, certain underlying obligations may be paid off substantially slower than originally anticipated and the value of those securities may fall sharply. During periods of falling interest rates, the income received by the Fund may decline. If the principal on a debt security is prepaid before expected, the prepayments of principal may have to be reinvested in obligations paying interest at lower rates. Debt securities generally do not trade on a securities exchange making them generally less liquid and more difficult to value than common stock.

Roundhill Developed Markets WeeklyPay™ ETF | DERIVATIVES RISK  
Prospectus [Line Items]  
Risk [Text Block]

DERIVATIVES RISK. The use of derivative instruments involves risks different from, or possibly greater than, the risks associated with investing directly in securities and other traditional investments. These risks include: (i) the risk that the counterparty to a derivative transaction may not fulfill its contractual obligations; (ii) risk of mispricing or improper valuation; and (iii) the risk that changes in the value of the derivative may not correlate perfectly with the underlying asset. Derivative prices are highly volatile and may fluctuate substantially during a short period of time. Such prices are influenced by numerous factors that affect the markets, including, but not limited to: changing supply and demand relationships; government programs and policies; national and international political and economic events, changes in interest rates, inflation and deflation and changes in supply and demand relationships. Trading derivative instruments involves risks different from, or possibly greater than, the risks associated with investing directly in securities. Derivative contracts ordinarily have leverage inherent in their terms. The use of leverage may cause the Fund to liquidate portfolio positions when it would not be advantageous to do so in order to satisfy its obligations or to meet regulatory or contractual requirements for derivatives. The use of derivatives can magnify potential for gain or loss and, therefore, amplify the effects of market volatility on share price.

Roundhill Developed Markets WeeklyPay™ ETF | DISTRIBUTION TAX RISK  
Prospectus [Line Items]  
Risk [Text Block]

DISTRIBUTION TAX RISK. The Fund currently expects to make distributions on a weekly basis. Such frequent distributions may expose investors to increased tax liabilities. However, these distributions may exceed the Fund’s income and gains for the Fund’s taxable year. Distributions in excess of the Fund’s current and accumulated earnings and profits will be treated as a return of capital. A return of capital distribution generally will not be taxable but will reduce the shareholder’s cost basis and will result in a higher capital gain or lower capital loss when those Fund Shares on which the distribution was received are sold. Once a Fund shareholder’s cost basis is reduced to zero, further distributions will be treated as capital gain if the Fund shareholder holds Fund Shares as capital assets. Additionally, any capital returned through distributions will be distributed after payment of Fund fees and expenses. Because a portion of the Fund’s distributions may consist of return of capital, the Fund may not be an appropriate investment for investors who do not want their principal investment in the Fund to decrease over time or who do not wish to receive return of capital in a given period. In the event that a shareholder purchases Fund Shares shortly before a distribution by the Fund, the entire distribution may be taxable to the shareholder even though a portion of the distribution effectively represents a return of the purchase price.

Roundhill Developed Markets WeeklyPay™ ETF | ETF RISK  
Prospectus [Line Items]  
Risk [Text Block]

ETF RISK. The Fund may invest in ETFs. The value of an ETF held by the Fund will fluctuate over time based on fluctuations in the values of the assets held by the ETF, which may be affected by changes in general economic conditions, expectations for future growth and profits, interest rates and the supply and demand for those assets. When the Fund invests in an ETF, it will bear a proportionate share of the ETF’s expenses. Brokerage, tax and other expenses may negatively impact the performance of the ETF and, in turn, the value of the Fund Shares. An ETF that tracks an index may not exactly match the performance of the index due to cash drag, differences between the portfolio of the ETF and the components of the index, expenses and other factors.

Roundhill Developed Markets WeeklyPay™ ETF | INFLATION RISK  
Prospectus [Line Items]  
Risk [Text Block]

INFLATION RISK. Inflation risk is the risk that the value of assets or income from investments will be less in the future as inflation decreases the value of money. As inflation increases, the present value of the Fund’s assets and distributions may decline. This risk is more prevalent with respect to fixed income securities held by the Fund.

Roundhill Developed Markets WeeklyPay™ ETF | Interest Rate Risk [Member]  
Prospectus [Line Items]  
Risk [Text Block]

INTEREST RATE RISK. Interest rate risk is the risk that the value of the debt securities in the Fund’s portfolio will decline because of rising market interest rates. Interest rate risk is generally lower for shorter term debt securities and higher for longer-term debt securities. Duration is a reasonably accurate measure of a debt security’s price sensitivity to changes in interest rates and a common measure of interest rate risk. Duration measures a debt security’s expected life on a present value basis, taking into account the debt security’s yield, interest payments and final maturity. In general, duration represents the expected percentage change in the value of a security for an immediate 1% change in interest rates. For example, the price of a debt security with a three-year duration would be expected to drop by approximately 3% in response to a 1% increase in interest rates. Therefore, prices of debt securities with shorter durations tend to be less sensitive to interest rate changes than debt securities with longer durations. As the value of a debt security changes over time, so will its duration.

Roundhill Developed Markets WeeklyPay™ ETF | LEGISLATION AND LITIGATION RISK  
Prospectus [Line Items]  
Risk [Text Block]

LEGISLATION AND LITIGATION RISK. Legislation or litigation that affects the value of assets or securities held by the Fund may reduce the value of the Fund. From time to time, various legislative initiatives are proposed that may have a negative impact on certain assets or securities in which the Fund invests. In addition, litigation regarding any of the assets or securities owned by the Fund may negatively impact the value of the Shares. Such legislation or litigation may cause the Fund to lose value or may result in higher portfolio turnover if the Adviser determines to sell such a holding.

Roundhill Developed Markets WeeklyPay™ ETF | LEVERAGE RISK  
Prospectus [Line Items]  
Risk [Text Block]

LEVERAGE RISK. The Fund obtains investment exposure in excess of its net assets by utilizing leverage and may lose more money in market conditions that are adverse to its investment objectives than a fund that does not utilize leverage. An investment in the Fund is exposed to the risk that a decline in the weekly performance of shares of the Developed Markets ETF will be magnified. This means that an investment in the Fund will be reduced by an amount equal to 1.2% for every 1% weekly decline in the market value of the Developed Markets ETF shares, not including the costs of financing leverage and other operating expenses, which would further reduce its value. The Fund could theoretically lose an amount greater than its net assets in the event the market value of the Developed Markets ETF shares decline more than 83.33% over a calendar week. Leverage will also have the effect of magnifying any differences in the Fund’s correlation with the Developed Markets ETF shares.

Roundhill Developed Markets WeeklyPay™ ETF | MONEY MARKET INSTRUMENTS RISK  
Prospectus [Line Items]  
Risk [Text Block]

MONEY MARKET INSTRUMENTS RISK. The value of money market instruments may be affected by changing interest rates and by changes in the credit ratings of the investments. If a significant amount of the Fund’s assets are invested in money market instruments, it will be more difficult for the Fund to achieve its investment objectives. An investment in a money market fund is not insured or guaranteed by the FDIC or any other government agency. It is possible to lose money by investing in a money market fund.

Roundhill Developed Markets WeeklyPay™ ETF | OPERATIONAL RISK  
Prospectus [Line Items]  
Risk [Text Block]

OPERATIONAL RISK. The Fund is subject to risks arising from various operational factors, including, but not limited to, human error, processing and communication errors, errors of the Fund’s service providers, counterparties or other third-parties, failed or inadequate processes and technology or systems failures. The Fund relies on third-parties for a range of services, including custody. Any delay or failure relating to engaging or maintaining such service providers may affect the Fund’s ability to meet its investment objectives. Although the Fund and the Adviser seek to reduce these operational risks through controls and procedures, there is no way to completely protect against such risks.

Roundhill Developed Markets WeeklyPay™ ETF | SPECIAL TAX RISK  
Prospectus [Line Items]  
Risk [Text Block]

SPECIAL TAX RISK. The Fund intends to qualify annually and to elect to be treated as a regulated investment company under the Internal Revenue Code of 1986, as amended (the “Code”). To qualify for the favorable U.S. federal income tax treatment generally accorded to regulated investment companies, the Fund must, among other things, (i) derive in each taxable year at least 90% of its gross income from dividends, interest, payments with respect to securities loans and gains from the sale or other disposition of stock, securities or foreign currencies or other income derived with respect to its business of investing in such stock, securities or currencies, or net income derived from interests in certain publicly traded partnerships; (ii) diversify its holdings so that, at the end of each quarter of the taxable year, (a) at least 50% of the market value of the Fund’s assets is represented by cash and cash items (including receivables), U.S. government securities, the securities of other regulated investment companies and other securities, with such other securities of any one issuer generally limited for the purposes of this calculation to an amount not greater than 5% of the value of the Fund’s total assets and not greater than 10% of the outstanding voting securities of such issuer, and (b) not more than 25% of the value of its total assets is invested in the securities (other than U.S. government securities or the securities of other regulated investment companies) of any one issuer, or two or more issuers which the Fund controls which are engaged in the same, similar or related trades or businesses, or the securities of one or more of certain publicly traded partnerships; and (iii) distribute at least 90% of its investment company taxable income (which includes, among other items, dividends, interest and net short-term capital gains in excess of net long-term capital losses) and at least 90% of its net tax-exempt interest income each taxable year. There are certain exceptions for failure to qualify if the failure is for reasonable cause or is de minimis, and certain corrective action is taken and certain tax payments are made by the Fund.

 

The authority with regard to swaps entered into by regulated investment companies is unclear both as to the qualification under the income test and the identification of the issuer under the diversification test. The Fund intends to take the position that because the swaps held by the Fund reference securities that the income on the swaps are “other income” from the Fund’s business of investing in stocks and securities. In addition, the Fund intends to manage its investments in the swaps so that neither the exposure to issuer of the referenced security nor the exposure to any one counterparty of the swaps will exceed 25% of the gross value of the Fund’s portfolio at the end of any quarter.

 

If the Fund were to fail to meet the qualifying income test or asset diversification test and fail to qualify as a RIC, it would be taxed in the same manner as an ordinary corporation, and distributions to its shareholders would not be deductible by the Fund in computing its taxable income, which would adversely affect the Fund’s performance.

Roundhill Developed Markets WeeklyPay™ ETF | STRUCTURAL ETF RISKS  
Prospectus [Line Items]  
Risk [Text Block]

STRUCTURAL ETF RISKS. The Fund is an ETF. Accordingly, it is subject to certain risks associated with its unique structure.

 

Market Participants Risk. Only an Authorized Participant may engage in creation or redemption transactions directly with the Fund, and none of those Authorized Participants is obligated to engage in creation and/or redemption transactions. The Fund has a limited number of institutions that may act as Authorized Participants on an agency basis (i.e., on behalf of other market participants). To the extent that Authorized Participants exit the business or are unable to proceed with creation or redemption orders with respect to the Fund and no other Authorized Participant is able to step forward to create or redeem, Fund Shares may be more likely to trade at a premium or discount to NAV and possibly face trading halts or delisting. The Fund may also rely on a small number of third-party market makers to provide a market for the purchase and sale of Fund Shares but such market makers are under no obligation to do so. Decisions by Authorized Participants or market makers to reduce their role or step away from these activities in times of market stress could inhibit the effectiveness of the arbitrage process in maintaining the relationship between the underlying values of the Fund’s portfolio securities and the Fund’s market price. Any trading halt or other problem relating to the trading activity of these market makers or any issues disrupting the Authorized Participants’ ability to proceed with creation and/or redemption orders could result in a dramatic change in the spread between the Fund’s net asset value and the price at which Fund Shares are trading on the Exchange, which could result in a decrease in value of Fund Shares. This reduced effectiveness could result in Fund Shares trading at a premium or discount to net asset value and also in greater than normal intraday bid-ask spreads Fund Shares.

 

Cash Transactions Risk. The Fund currently expects to effect a significant portion of its creations and redemptions for cash, rather than in-kind securities. Paying redemption proceeds in cash rather than through in-kind delivery of portfolio securities may require the Fund to dispose of or sell portfolio securities or other assets at an inopportune time to obtain the cash needed to meet redemption orders. This may cause the Fund to sell a security and recognize a capital gain or loss that might not have been incurred if it had made a redemption in-kind. As a result, the Fund may pay out higher or lower annual capital gains distributions than ETFs that redeem in-kind. The use of cash creations and redemptions may also cause the Fund’s Shares to trade in the market at greater bid-ask spreads or greater premiums or discounts to the Fund’s NAV. Furthermore, the Fund may not be able to execute cash transactions for creation and redemption purposes at the same price used to determine the Fund’s NAV. To the extent that the maximum additional charge for creation or redemption transactions is insufficient to cover the execution shortfall, the Fund’s performance could be negatively impacted.

 

Costs of Buying and Selling Fund Shares. Due to the costs of buying or selling Fund Shares, including brokerage commissions imposed by brokers and bid/ask spreads, frequent trading of Fund Shares may significantly reduce investment results and an investment in Fund Shares may not be advisable for investors who anticipate regularly making small investments.

 

Premium/Discount Risk. As with all ETFs, Fund Shares may be bought and sold in the secondary market at market prices. The trading prices of Fund Shares in the secondary market may differ from the Fund’s daily net asset value per share and there may be times when the market price of the shares is more than the net asset value per share (premium) or less than the net asset value per share (discount). If a shareholder purchases Fund Shares at a time when the market price is at a premium to the net asset value or sells Fund Shares at a time when the market price is at a discount to the net asset value, the shareholder may pay more for, or receive less than, the underlying value of the Fund Shares, respectively. This risk is heightened in times of market volatility or periods of steep market declines.

 

Trading Risks. Although Fund Shares are listed for trading on the Exchange and may be traded on U.S. exchanges other than the Exchange, there can be no assurance that Fund Shares will trade with any volume, or at all, on any stock exchange. In stressed market conditions, the liquidity of Fund Shares may begin to mirror the liquidity of the Fund’s underlying portfolio holdings, which can be significantly less liquid than Fund Shares. Trading in Fund Shares on the Exchange may be halted due to market conditions or for reasons that, in the view of the Exchange, make trading in Fund Shares inadvisable. In addition, trading in Fund Shares on the Exchange is subject to trading halts caused by extraordinary market volatility pursuant to the Exchange’s “circuit breaker” rules. There can be no assurance that the requirements of the Exchange necessary to maintain the listing of the Fund will continue to be met or will remain unchanged.

Roundhill Developed Markets WeeklyPay™ ETF | U.S. GOVERNMENT SECURITIES RISK  
Prospectus [Line Items]  
Risk [Text Block]

U.S. GOVERNMENT SECURITIES RISK. U.S. government securities are subject to interest rate risk but generally do not involve the credit risks associated with investments in other types of debt securities. As a result, the yields available from U.S. government securities are generally lower than the yields available from other debt securities. U.S. government securities are guaranteed only as to the timely payment of interest and the payment of principal when held to maturity.

Roundhill Developed Markets WeeklyPay™ ETF | VALUATION RISK  
Prospectus [Line Items]  
Risk [Text Block]

VALUATION RISK. The Fund may hold securities or other assets that may be valued on the basis of factors other than market quotations. This may occur because the asset or security does not trade on a centralized exchange, or in times of market turmoil or reduced liquidity. There are multiple methods that can be used to value a portfolio holding when market quotations are not readily available. The value established for any portfolio holding at a point in time might differ from what would be produced using a different methodology or if it had been priced using market quotations. Portfolio holdings that are valued using techniques other than market quotations, including “fair valued” assets or securities, may be subject to greater fluctuation in their valuations from one day to the next than if market quotations were used. In addition, there is no assurance that the Fund could sell or close out a portfolio position for the value established for it at any time, and it is possible that the Fund would incur a loss because a portfolio position is sold or closed out at a discount to the valuation established by the Fund at that time. The Fund’s ability to value investments may be impacted by technological issues or errors by pricing services or other third-party service providers.

Roundhill Developed Markets WeeklyPay™ ETF | EQUITY SECURITIES RISK  
Prospectus [Line Items]  
Risk [Text Block]

EQUITY SECURITIES RISK. Equity securities are subject to changes in value, and their values may be more volatile than those of other asset classes. Equity securities prices fluctuate for several reasons, including changes in investors’ perceptions of the financial condition of an issuer or the general condition of the relevant equity market, such as market volatility, or when political or economic events affecting an issuer occur. Common stock prices may be particularly sensitive to rising interest rates, as the cost of capital rises and borrowing costs increase. Common stocks generally subject their holders to more risks than preferred stocks and debt securities because common stockholders’ claims are subordinated to those of holders of preferred stocks and debt securities upon the bankruptcy of the issuer.

Roundhill Developed Markets WeeklyPay™ ETF | SWAP AGREEMENTS RISK  
Prospectus [Line Items]  
Risk [Text Block]

SWAP AGREEMENTS RISK. The Fund will utilize swap agreements to derive its exposure to shares of the Developed Markets ETF. Swap agreements may involve greater risks than direct investment in securities as they may be leveraged and are subject to credit risk, counterparty risk and valuation risk. A swap agreement could result in losses if the underlying reference or asset does not perform as anticipated. In addition, many swaps trade over-the-counter and may be considered illiquid. It may not be possible for the Fund to liquidate a swap position at an advantageous time or price, which may result in significant losses.

Roundhill Developed Markets WeeklyPay™ ETF | NEW FUND RISK  
Prospectus [Line Items]

NEW FUND RISK. The Fund is a recently organized investment company with a limited operating history. As a result, prospective investors have a limited track record or history on which to base their investment decision.

Roundhill Developed Markets WeeklyPay™ ETF | REGULATED INVESTMENT COMPANY TAX RISKS  
Prospectus [Line Items]  
Risk [Text Block]

REGULATED INVESTMENT COMPANY TAX RISKS. The Fund intends to qualify annually and to elect to be treated as a regulated investment company under the Internal Revenue Code of 1986, as amended (the “Code”). To qualify for the favorable U.S. federal income tax treatment generally accorded to regulated investment companies, the Fund must, among other things, (i) derive in each taxable year at least 90% of its gross income from dividends, interest, payments with respect to securities loans and gains from the sale or other disposition of stock, securities or foreign currencies or other income derived with respect to its business of investing in such stock, securities or currencies, or net income derived from interests in certain publicly traded partnerships; (ii) diversify its holdings so that, at the end of each quarter of the taxable year, (a) at least 50% of the market value of the Fund’s assets is represented by cash and cash items (including receivables), U.S. government securities, the securities of other regulated investment companies and other securities, with such other securities of any one issuer generally limited for the purposes of this calculation to an amount not greater than 5% of the value of the Fund’s total assets and not greater than 10% of the outstanding voting securities of such issuer, and (b) not more than 25% of the value of its total assets is invested in the securities (other than U.S. government securities or the securities of other regulated investment companies) of any one issuer, or two or more issuers which the Fund controls which are engaged in the same, similar or related trades or businesses, or the securities of one or more of certain publicly traded partnerships; and (iii) distribute at least 90% of its investment company taxable income (which includes, among other items, dividends, interest and net short-term capital gains in excess of net long-term capital losses) and at least 90% of its net tax-exempt interest income each taxable year. There are certain exceptions for failure to qualify if the failure is for reasonable cause or is de minimis, and certain corrective action is taken and certain tax payments are made by the Fund.

 

If the Fund were to fail to meet the qualifying income test or asset diversification test and fail to qualify as a RIC, it would be taxed in the same manner as an ordinary corporation, and distributions to its shareholders would not be deductible by the Fund in computing its taxable income, which would adversely affect the Fund’s performance.

Roundhill Developed Markets WeeklyPay™ ETF | LARGE SHAREHOLDER RISK  
Prospectus [Line Items]  
Risk [Text Block]

LARGE SHAREHOLDER RISK. Certain shareholders, including affiliated funds advised by the Adviser, may from time to time own a significant portion of the Fund’s shares. In addition, a third-party investor, the Adviser or an affiliate of the Adviser (“Affiliate”), an authorized participant, a market maker, or another entity may invest in the Fund and hold its investment for a limited period solely to facilitate the commencement of the Fund or to help the Fund achieve a specified size or scale. There can be no assurance that any large shareholder will not redeem its investment, that the size of the Fund will be maintained at such levels, or that the Fund will continue to meet applicable listing requirements. Redemptions by large shareholders could have a significant negative impact on the Fund. In addition, transactions by large shareholders may account for a large percentage of the trading volume on the Fund’s listing exchange and may, therefore, have a material upward or downward effect on the market price of the shares.

 

To the extent that a significant percentage of the Fund’s shares are owned or controlled by a small number of account shareholders (or a single account shareholder), including funds or accounts over which the Adviser or an Affiliate has investment discretion, the Fund is subject to the risk that those shareholders may purchase or redeem Fund shares in significant amounts rapidly or unexpectedly, including as a result of an asset allocation decision made by the Adviser or an Affiliate. This may adversely affect the Fund’s performance if the Adviser is forced to sell portfolio securities or invest cash when it would not otherwise choose to do so. Redemptions of a large number of shares may affect the liquidity of the Fund’s portfolio, increase the Fund’s transaction costs, and accelerate the realization of taxable income and/or gains. In addition, a large redemption could result in the Fund’s current expenses being allocated over a smaller asset base, leading to an increase in the Fund’s gross expense ratio. Large purchases of the Fund’s shares may also adversely affect the Fund’s performance to the extent that the Fund is delayed in investing new cash or otherwise maintains a larger cash position than it ordinarily would, particularly if the Fund accepts cash for an order for the purchase of creation units of the Fund’s shares.

Roundhill Developed Markets WeeklyPay™ ETF | DEVELOPED MARKETS ETF INVESTING RISKS  
Prospectus [Line Items]  
Risk [Text Block]

DEVELOPED MARKETS ETF INVESTING RISKS. The Fund will have significant exposure to the Developed Markets ETF through its investments in shares of the Developed Markets ETF and swap agreements that utilize the Developed Markets ETF as the reference asset. Accordingly, the Fund will subject to the risks of the Developed Markets ETF, set forth below. In addition to these risks, the Developed Markets ETF is also subject to the following risks to which the Fund is also subject, which are described within the section entitled “Principal Risks”: Market Risk, Asset Class Risk, Concentration Risk, Current Market Conditions Risk, Cybersecurity Risk, Equity Securities Risk, Operational Risk and Structural ETF Risk.

 

CURRENCY RISK. Because the Developed Markets ETF’s NAV is determined in U.S. dollars, the NAV could decline if the currency of a non-U.S. market in which the Developed Markets ETF invests depreciates against the U.S. dollar or if there are delays or limits on the repatriation of foreign currency. Currency exchange rates can be very volatile and can change quickly and unpredictably. As a result, the Developed Markets ETF’s NAV may change quickly and without warning. In addition, the Developed Markets ETF may incur costs in connection with conversions between U.S. dollars and foreign currencies.

 

INDEX-RELATED RISK. The Developed Markets ETF Index Provider may rely on various sources of information to assess the criteria of components of the Developed Markets ETF Index, including information that may be based on assumptions and estimates. Neither the Developed Markets ETF nor its investment adviser offer assurances that the Developed Markets ETF Index Provider’s methodology or sources of information will provide an accurate assessment of included components or will result in the Developed Markets ETF meeting its investment objective. Errors in index data, index computations or the construction of the Developed Markets ETF Index in accordance with its methodology may occur, and the Developed Markets ETF Index Provider may not identify or correct them promptly or at all, which may have an adverse impact on the Developed Markets ETF and its shareholders. Unusual market conditions or other unforeseen circumstances (such as natural disasters, political unrest or war) may impact the Developed Markets ETF Index Provider or a third-party data provider and could cause the Developed Markets ETF Index Provider to postpone a scheduled rebalance. This could cause the Developed Markets ETF Index to vary from its normal or expected composition.

 

INDIRECT INVESTMENT RISK. The Developed Markets ETF is not affiliated with the Trust, the Fund, the Adviser, the Sub-Adviser or any affiliates thereof and is not involved with this offering in any way, and has no obligation to consider the Fund in taking any actions that might affect the value of the Fund. The Trust, the Fund, the Adviser, the Sub-Adviser or any affiliate are not responsible for the performance of the Developed Markets ETF and make no representation as to the performance of the Developed Markets ETF. Investing in the Fund is not equivalent to investing in the Developed Markets ETF Fund shareholders will not have voting rights or rights to receive dividends or other distributions or any other rights with respect to the Developed Markets ETF.

 

LARGE CAPITALIZATION COMPANIES RISK. Large capitalization companies may be less able than smaller capitalization companies to adapt to changing market conditions. Large capitalization companies may be more mature and subject to more limited growth potential compared with smaller capitalization companies. During different market cycles, the performance of large capitalization companies has trailed the overall performance of the broader securities markets.

 

MID-CAPITALIZATION COMPANIES RISK. Compared to large capitalization companies, mid-capitalization companies may be less stable and more susceptible to adverse developments. The securities of mid-capitalization companies may be more volatile and less liquid than those of large-capitalization companies. As a result, the Developed Markets ETF’s share price may be more volatile than that of a fund with a greater investment in large-capitalization stocks.

 

NON-U.S. SECURITIES RISK. Securities issued by non-U.S. issuers (including depositary receipts) are subject to different legal, regulatory, political, economic, and market risks than securities issued by U.S. issuers. These risks include greater market volatility, less market liquidity, higher transaction costs, expropriation, confiscatory taxation, adverse changes in foreign investment or currency control regulations, restrictions on the repatriation of capital, and political instability. Non-U.S. issuers may be subject to different accounting, audit and financial reporting standards than U.S. issuers, and there may be less publicly available information about non-U.S. issuers. Foreign market trading hours, different clearing and settlement procedures, and holiday schedules may limit the Developed Markets ETF’s ability to engage in portfolio transactions. To the extent that investments are made in a limited number of countries, events in those countries will have a more significant impact on the Developed Markets ETF.

 

RISK OF INVESTING IN DEVELOPED MARKETS. The Developed Markets ETF’s investment in developed country issuers will subject the Developed Markets ETF to legal, regulatory, political, currency, security, economic and other risks associated with developed countries. Developed countries tend to represent a significant portion of the global economy and have generally experienced slower economic growth than some less developed countries. Certain developed countries have experienced security concerns, such as war, terrorism and strained international relations. Incidents involving a country’s or region’s security may cause uncertainty in its markets and may adversely affect its economy and the Developed Markets ETF’s investments. In addition, developed countries may be adversely impacted by changes to the economic conditions of certain key trading partners, regulatory burdens, debt burdens and the price or availability of certain commodities.

 

RISK OF INVESTING IN JAPAN. Investing in Japanese issuers subjects the Developed Market ETF to legal, regulatory, political, economic, currency, geographic and security risks that are specific to Japan. Japan’s economy depends heavily on international trade, oil and other commodity imports, and government policy supporting its exports. Other risks facing the Japanese economy include significant public debt and deficits, currency fluctuations, and labor shortages due to an aging and declining population. Japan’s relations with its neighbors have been strained at times, which could adversely affect its markets and economy. Japan is also vulnerable to natural disasters.

NON-DIVERSIFICATION RISK. As a “non-diversified” fund, the Fund may hold a smaller number of portfolio securities than many other funds. To the extent the Fund invests in a relatively small number of issuers, a decline in the market value of a particular security held by the Fund may affect its value more than if it invested in a larger number of issuers. The value of the Fund Shares may be more volatile than the values of shares of more diversified funds.

Roundhill Ether WeeklyPay™ ETF | MARKET RISK  
Prospectus [Line Items]  
Risk [Text Block]

MARKET RISK. Market risk is the risk that a particular investment, or Fund Shares in general, may fall in value. Securities are subject to market fluctuations caused by real or perceived adverse economic, political, and regulatory factors or market developments, changes in interest rates, disruptions to trade, impositions of tariffs and perceived trends in securities prices. Fund Shares could decline in value or underperform other investments. In addition, local, regional or global events such as war, acts of terrorism, market manipulation, government defaults, government shutdowns, regulatory actions, political changes, diplomatic developments, the imposition of sanctions and other similar measures, spread of infectious diseases or other public health issues, recessions, natural disasters, or other events could have a significant negative impact on the Fund and its investments. Any of such circumstances could have a materially negative impact on the value of Fund Shares, the liquidity of an investment, and may result in increased market volatility. During any such events, Fund Shares may trade at increased premiums or discounts to their net asset value, the bid/ask spread on Fund Shares may widen and the returns on investment may fluctuate.

LIQUIDITY RISK. The market for swap agreements that reference the Ether ETF shares may be subject to periods of illiquidity. During such times it may be difficult or impossible to buy or sell a position at the desired price. Market disruptions or volatility can also make it difficult to find a counterparty willing to transact at a reasonable price and sufficient size. Illiquid markets may cause losses, which could be significant. The large size of the positions which the Fund may acquire increases the risk of illiquidity, may make its positions more difficult to liquidate, and may increase the losses incurred while trying to do so. Such large positions also may impact the price of swap agreements on the Ether ETF shares.

ACTIVE MANAGEMENT RISK. The Fund is actively-managed and its performance reflects investment decisions that the Adviser and/or Sub-Adviser makes for the Fund. Such judgments about the Fund’s investments may prove to be incorrect. If the investments selected and the strategies employed by the Fund fail to produce the intended results, the Fund could underperform as compared to other funds with similar investment objectives and/or strategies, or could have negative returns.

ACTIVE MARKET RISK. Although Fund Shares are listed for trading on the Exchange, there can be no assurance that an active trading market for Fund Shares will develop or be maintained. Fund Shares trade on the Exchange at market prices that may be below, at or above the Fund’s net asset value. Securities, including Fund Shares, are subject to market fluctuations and liquidity constraints that may be caused by such factors as economic, political, or regulatory developments, changes in interest rates, and/or perceived trends in securities prices. Fund Shares could decline in value or underperform other investments.

CONCENTRATION RISK. The Fund is susceptible to an increased risk of loss, including losses due to adverse events that affect the Fund’s investments more than the market as a whole, to the extent that the Fund’s investments are concentrated in investments or instruments that provide exposure to ether.

Roundhill Ether WeeklyPay™ ETF | COUNTERPARTY RISK

Risk [Text Block]

COUNTERPARTY RISK. Fund transactions involving a counterparty are subject to the risk that the counterparty will not fulfill its obligation to the Fund. Counterparty risk may arise because of the counterparty’s financial condition (i.e., financial difficulties, bankruptcy, or insolvency), market activities and developments, or other reasons, whether foreseen or not. A counterparty’s inability to fulfill its obligation may result in significant financial loss to the Fund. The Fund may be unable to recover its investment from the counterparty or may obtain a limited recovery, and/or recovery may be delayed.

CREDIT RISK. An issuer or other obligated party of a debt security may be unable or unwilling to make dividend, interest and/or principal payments when due. In addition, the value of a debt security may decline because of concerns about the issuer’s ability or unwillingness to make such payments.

Roundhill Ether WeeklyPay™ ETF | CURRENT MARKET CONDITIONS RISK  
Prospectus [Line Items]  
Risk [Text Block]

CURRENT MARKET CONDITIONS RISK. Current market conditions risk is the risk that a particular investment, or Fund Shares in general, may fall in value due to current market conditions. As a means to fight inflation, which remains at elevated levels, the Federal Reserve and certain foreign central banks have raised interest rates; however, the Federal Reserve has recently lowered interest rates and may continue to do so. U.S. regulators have proposed several changes to market and issuer regulations which would directly impact the Fund, and any regulatory changes could adversely impact the Fund’s ability to achieve its investment strategies or make certain investments. Recent and potential future bank failures could result in disruption to the broader banking industry or markets generally and reduce confidence in financial institutions and the economy as a whole, which may also heighten market volatility and reduce liquidity. Additionally, challenges in commercial real estate markets, including rising interest rates, declining valuations and increasing vacancies, could have a broader impact on financial markets. The ongoing adversarial political climate in the United States, as well as political and diplomatic events both domestic and abroad, have and may continue to have an adverse impact the U.S. regulatory landscape, markets and investor behavior, which could have a negative impact on the Fund’s investments and operations. The change in administration resulting from the 2024 United States national elections could result in significant impacts to international trade relations, tax and immigration policies, and other aspects of the national and international political and financial landscape, which could affect, among other things, inflation and the securities markets generally. Other unexpected political, regulatory and diplomatic events within the U.S. and abroad may affect investor and consumer confidence and may adversely impact financial markets and the broader economy. For example, ongoing armed conflicts between Russia and Ukraine in Europe and among Israel, Iran, Hamas and other militant groups in the Middle East, have caused and could continue to cause significant market disruptions and volatility within the markets in Russia, Europe, the Middle East and the United States. The hostilities and sanctions resulting from those hostilities have and could continue to have a significant impact on certain Fund investments as well as Fund performance and liquidity. The economies of the United States and its trading partners, as well as the financial markets generally, may be adversely impacted by trade disputes, including the imposition of tariffs, and other matters. For example, the United States has imposed trade barriers and restrictions on China. In addition, the Chinese government is engaged in a longstanding dispute with Taiwan, continually threatening an invasion. If the political climate between the United States and China does not improve or continues to deteriorate, if China were to attempt invading Taiwan, or if other geopolitical conflicts develop or worsen, economies, markets and individual securities may be adversely affected, and the value of the Fund’s assets may go down. A public health crisis and the ensuing policies enacted by governments and central banks may cause significant volatility and uncertainty in global financial markets, negatively impacting global growth prospects. As the COVID-19 global pandemic illustrated, such events may affect certain geographic regions, countries, sectors and industries more significantly than others. Advancements in technology may also adversely impact markets and the overall performance of the Fund. For instance, the economy may be significantly impacted by the advanced development and increased regulation of artificial intelligence. Additionally, cyber security breaches of both government and non-government entities could have negative impacts on infrastructure and the ability of such entities, including the Fund, to operate properly. These events, and any other future events, may adversely affect the prices and liquidity of the Fund’s portfolio investments and could result in disruptions in the trading markets.

Roundhill Ether WeeklyPay™ ETF | CYBERSECURITY RISK  
Prospectus [Line Items]  
Risk [Text Block]

CYBERSECURITY RISK. Failures or breaches of the electronic systems of the Fund, the Fund’s adviser, sub-adviser, distributor and other service providers, market makers, Authorized Participants or the issuers of securities in which the Fund invests have the ability to cause disruptions, negatively impact the Fund’s business operations and/or potentially result in financial losses to the Fund and its shareholders. While the Fund has established business continuity plans and risk management systems seeking to address system breaches or failures, there are inherent limitations in such plans and systems. Furthermore, the Fund cannot control the cybersecurity plans and systems of the Fund’s other service providers, market makers, Authorized Participants or issuers of securities in which the Fund invests.

Roundhill Ether WeeklyPay™ ETF | DEBT SECURITIES RISK  
Prospectus [Line Items]  
Risk [Text Block]

DEBT SECURITIES RISK. Investments in debt securities subject the holder to the credit risk of the issuer. Credit risk refers to the possibility that the issuer or other obligor of a security will not be able or willing to make payments of interest and principal when due. Generally, the value of debt securities will change inversely with changes in interest rates. To the extent that interest rates rise, certain underlying obligations may be paid off substantially slower than originally anticipated and the value of those securities may fall sharply. During periods of falling interest rates, the income received by the Fund may decline. If the principal on a debt security is prepaid before expected, the prepayments of principal may have to be reinvested in obligations paying interest at lower rates. Debt securities generally do not trade on a securities exchange making them generally less liquid and more difficult to value than common stock.

Roundhill Ether WeeklyPay™ ETF | DERIVATIVES RISK  
Prospectus [Line Items]  
Risk [Text Block]

DERIVATIVES RISK. The use of derivative instruments involves risks different from, or possibly greater than, the risks associated with investing directly in securities and other traditional investments. These risks include: (i) the risk that the counterparty to a derivative transaction may not fulfill its contractual obligations; (ii) risk of mispricing or improper valuation; and (iii) the risk that changes in the value of the derivative may not correlate perfectly with the underlying asset. Derivative prices are highly volatile and may fluctuate substantially during a short period of time. Such prices are influenced by numerous factors that affect the markets, including, but not limited to: changing supply and demand relationships; government programs and policies; national and international political and economic events, changes in interest rates, inflation and deflation and changes in supply and demand relationships. Trading derivative instruments involves risks different from, or possibly greater than, the risks associated with investing directly in securities. Derivative contracts ordinarily have leverage inherent in their terms. The use of leverage may cause the Fund to liquidate portfolio positions when it would not be advantageous to do so in order to satisfy its obligations or to meet regulatory or contractual requirements for derivatives. The use of derivatives can magnify potential for gain or loss and, therefore, amplify the effects of market volatility on share price.

Roundhill Ether WeeklyPay™ ETF | DISTRIBUTION TAX RISK  
Prospectus [Line Items]  
Risk [Text Block]

DISTRIBUTION TAX RISK. The Fund currently expects to make distributions on a weekly basis. Such frequent distributions may expose investors to increased tax liabilities. However, these distributions may exceed the Fund’s income and gains for the Fund’s taxable year. Distributions in excess of the Fund’s current and accumulated earnings and profits will be treated as a return of capital. A return of capital distribution generally will not be taxable but will reduce the shareholder’s cost basis and will result in a higher capital gain or lower capital loss when those Fund Shares on which the distribution was received are sold. Once a Fund shareholder’s cost basis is reduced to zero, further distributions will be treated as capital gain if the Fund shareholder holds Fund Shares as capital assets. Additionally, any capital returned through distributions will be distributed after payment of Fund fees and expenses. Because a portion of the Fund’s distributions may consist of return of capital, the Fund may not be an appropriate investment for investors who do not want their principal investment in the Fund to decrease over time or who do not wish to receive return of capital in a given period. In the event that a shareholder purchases Fund Shares shortly before a distribution by the Fund, the entire distribution may be taxable to the shareholder even though a portion of the distribution effectively represents a return of the purchase price.

Roundhill Ether WeeklyPay™ ETF | ETF RISK  
Prospectus [Line Items]  
Risk [Text Block]

ETF RISK. The Fund may invest in ETFs. The value of an ETF held by the Fund will fluctuate over time based on fluctuations in the values of the assets held by the ETF, which may be affected by changes in general economic conditions, expectations for future growth and profits, interest rates and the supply and demand for those assets. When the Fund invests in an ETF, it will bear a proportionate share of the ETF’s expenses. Brokerage, tax and other expenses may negatively impact the performance of the ETF and, in turn, the value of the Fund Shares. An ETF that tracks an index may not exactly match the performance of the index due to cash drag, differences between the portfolio of the ETF and the components of the index, expenses and other factors.

Roundhill Ether WeeklyPay™ ETF | INFLATION RISK  
Prospectus [Line Items]  
Risk [Text Block]

INFLATION RISK. Inflation risk is the risk that the value of assets or income from investments will be less in the future as inflation decreases the value of money. As inflation increases, the present value of the Fund’s assets and distributions may decline. This risk is more prevalent with respect to fixed income securities held by the Fund.

Roundhill Ether WeeklyPay™ ETF | Interest Rate Risk [Member]  
Prospectus [Line Items]  
Risk [Text Block]

INTEREST RATE RISK. Interest rate risk is the risk that the value of the debt securities in the Fund’s portfolio will decline because of rising market interest rates. Interest rate risk is generally lower for shorter term debt securities and higher for longer-term debt securities. Duration is a reasonably accurate measure of a debt security’s price sensitivity to changes in interest rates and a common measure of interest rate risk. Duration measures a debt security’s expected life on a present value basis, taking into account the debt security’s yield, interest payments and final maturity. In general, duration represents the expected percentage change in the value of a security for an immediate 1% change in interest rates. For example, the price of a debt security with a three-year duration would be expected to drop by approximately 3% in response to a 1% increase in interest rates. Therefore, prices of debt securities with shorter durations tend to be less sensitive to interest rate changes than debt securities with longer durations. As the value of a debt security changes over time, so will its duration.

Roundhill Ether WeeklyPay™ ETF | LEGISLATION AND LITIGATION RISK  
Prospectus [Line Items]  
Risk [Text Block]

LEGISLATION AND LITIGATION RISK. Legislation or litigation that affects the value of assets or securities held by the Fund may reduce the value of the Fund. From time to time, various legislative initiatives are proposed that may have a negative impact on certain assets or securities in which the Fund invests. In addition, litigation regarding any of the assets or securities owned by the Fund may negatively impact the value of the Shares. Such legislation or litigation may cause the Fund to lose value or may result in higher portfolio turnover if the Adviser determines to sell such a holding.

Roundhill Ether WeeklyPay™ ETF | LEVERAGE RISK  
Prospectus [Line Items]  
Risk [Text Block]

LEVERAGE RISK. The Fund obtains investment exposure in excess of its net assets by utilizing leverage and may lose more money in market conditions that are adverse to its investment objectives than a fund that does not utilize leverage. An investment in the Fund is exposed to the risk that a decline in the weekly performance of shares of the Ether ETF will be magnified. This means that an investment in the Fund will be reduced by an amount equal to 1.2% for every 1% weekly decline in the market value of the Ether ETF shares, not including the costs of financing leverage and other operating expenses, which would further reduce its value. The Fund could theoretically lose an amount greater than its net assets in the event the market value of the Ether ETF shares decline more than 83.33% over a calendar week. Leverage will also have the effect of magnifying any differences in the Fund’s correlation with the Ether ETF shares.

Roundhill Ether WeeklyPay™ ETF | MONEY MARKET INSTRUMENTS RISK  
Prospectus [Line Items]  
Risk [Text Block]

MONEY MARKET INSTRUMENTS RISK. The value of money market instruments may be affected by changing interest rates and by changes in the credit ratings of the investments. If a significant amount of the Fund’s assets are invested in money market instruments, it will be more difficult for the Fund to achieve its investment objectives. An investment in a money market fund is not insured or guaranteed by the FDIC or any other government agency. It is possible to lose money by investing in a money market fund.

Roundhill Ether WeeklyPay™ ETF | OPERATIONAL RISK  
Prospectus [Line Items]  
Risk [Text Block]

OPERATIONAL RISK. The Fund is subject to risks arising from various operational factors, including, but not limited to, human error, processing and communication errors, errors of the Fund’s service providers, counterparties or other third-parties, failed or inadequate processes and technology or systems failures. The Fund relies on third-parties for a range of services, including custody. Any delay or failure relating to engaging or maintaining such service providers may affect the Fund’s ability to meet its investment objectives. Although the Fund and the Adviser seek to reduce these operational risks through controls and procedures, there is no way to completely protect against such risks.

Roundhill Ether WeeklyPay™ ETF | SPECIAL TAX RISK  
Prospectus [Line Items]  
Risk [Text Block]

SPECIAL TAX RISK. The Fund intends to qualify as a “regulated investment company” (“RIC”), however, the federal income tax treatment of certain aspects of the proposed operations of the Fund are not entirely clear. This includes the tax aspects of the Fund’s options strategy, the possible application of the “straddle” rules, and various loss limitation provisions of the Internal Revenue Code of 1986, as amended (the “Code”). If, in any year, the Fund fails to qualify as a RIC under the applicable tax laws, the Fund would be taxed as an ordinary corporation.

 

The Fund intends to treat the income it derives from gains on swaps referencing the Ether ETF as “qualifying income” for purposes of the RIC qualification rules under Subchapter M of the Code. It has adopted this position in reliance on an opinion obtained from counsel that income from such investments should constitute “qualifying income,” as shares of the Ether ETF constitute “securities” under Section 2(a)(36) of the 1940 Act. However, this opinion is not binding upon the Internal Revenue Service (“IRS”). If the IRS were to successfully assert that the Fund’s income from such investments was not “qualifying income,” the Fund may fail to qualify as a RIC under Subchapter M if over 10% of its gross income was derived from these investments. If the Fund failed to qualify as a RIC, it would be subject to federal and state income tax on all of its taxable income at regular corporate tax rates with no deduction for any distributions paid to shareholders, which would significantly adversely affect the returns to, and could cause substantial losses for, Fund shareholders.

 

To maintain its status as a RIC, the Fund must distribute 90% of its investment company taxable income annually. In addition, to avoid a non-deductible excise tax, the Fund must distribute 98% of its ordinary income and 98.2% of its capital gain net income. Separately, depending upon the circumstances, sales to fund redemptions could cause the Fund to recognize income that the Fund is required to distribute to maintain the Fund’s RIC status and avoid the excise tax. Funding such distributions could require additional sales, which could require more distributions and affect the projected performance of the Fund. Alternatively, if the Fund only makes distributions to maintain its RIC status and becomes subject to the excise tax, that could also affect the projected performance of the Fund. In either case, the assets sold to fund redemptions, distributions or pay the excise tax will not be available to assist the Fund in meeting its investment objectives.

 

In the event that a shareholder purchases shares of the Fund shortly before a distribution by the Fund, the entire distribution may be taxable to the shareholder even though a portion of the distribution effectively represents a return of the purchase price.

Roundhill Ether WeeklyPay™ ETF | STRUCTURAL ETF RISKS  
Prospectus [Line Items]  
Risk [Text Block]

STRUCTURAL ETF RISKS. The Fund is an ETF. Accordingly, it is subject to certain risks associated with its unique structure.

 

Market Participants Risk. Only an Authorized Participant may engage in creation or redemption transactions directly with the Fund, and none of those Authorized Participants is obligated to engage in creation and/or redemption transactions. The Fund has a limited number of institutions that may act as Authorized Participants on an agency basis (i.e., on behalf of other market participants). To the extent that Authorized Participants exit the business or are unable to proceed with creation or redemption orders with respect to the Fund and no other Authorized Participant is able to step forward to create or redeem, Fund Shares may be more likely to trade at a premium or discount to NAV and possibly face trading halts or delisting. The Fund may also rely on a small number of third-party market makers to provide a market for the purchase and sale of Fund Shares but such market makers are under no obligation to do so. Decisions by Authorized Participants or market makers to reduce their role or step away from these activities in times of market stress could inhibit the effectiveness of the arbitrage process in maintaining the relationship between the underlying values of the Fund’s portfolio securities and the Fund’s market price. Any trading halt or other problem relating to the trading activity of these market makers or any issues disrupting the Authorized Participants’ ability to proceed with creation and/or redemption orders could result in a dramatic change in the spread between the Fund’s net asset value and the price at which Fund Shares are trading on the Exchange, which could result in a decrease in value of Fund Shares. This reduced effectiveness could result in Fund Shares trading at a premium or discount to net asset value and also in greater than normal intraday bid-ask spreads Fund Shares.

 

Cash Transactions Risk. The Fund currently expects to effect a significant portion of its creations and redemptions for cash, rather than in-kind securities. Paying redemption proceeds in cash rather than through in-kind delivery of portfolio securities may require the Fund to dispose of or sell portfolio securities or other assets at an inopportune time to obtain the cash needed to meet redemption orders. This may cause the Fund to sell a security and recognize a capital gain or loss that might not have been incurred if it had made a redemption in-kind. As a result, the Fund may pay out higher or lower annual capital gains distributions than ETFs that redeem in-kind. The use of cash creations and redemptions may also cause the Fund’s Shares to trade in the market at greater bid-ask spreads or greater premiums or discounts to the Fund’s NAV. Furthermore, the Fund may not be able to execute cash transactions for creation and redemption purposes at the same price used to determine the Fund’s NAV. To the extent that the maximum additional charge for creation or redemption transactions is insufficient to cover the execution shortfall, the Fund’s performance could be negatively impacted.

 

Costs of Buying and Selling Fund Shares. Due to the costs of buying or selling Fund Shares, including brokerage commissions imposed by brokers and bid/ask spreads, frequent trading of Fund Shares may significantly reduce investment results and an investment in Fund Shares may not be advisable for investors who anticipate regularly making small investments.

 

Premium/Discount Risk. As with all ETFs, Fund Shares may be bought and sold in the secondary market at market prices. The trading prices of Fund Shares in the secondary market may differ from the Fund’s daily net asset value per share and there may be times when the market price of the shares is more than the net asset value per share (premium) or less than the net asset value per share (discount). If a shareholder purchases Fund Shares at a time when the market price is at a premium to the net asset value or sells Fund Shares at a time when the market price is at a discount to the net asset value, the shareholder may pay more for, or receive less than, the underlying value of the Fund Shares, respectively. This risk is heightened in times of market volatility or periods of steep market declines.

 

Trading Risks. Although Fund Shares are listed for trading on the Exchange and may be traded on U.S. exchanges other than the Exchange, there can be no assurance that Fund Shares will trade with any volume, or at all, on any stock exchange. In stressed market conditions, the liquidity of Fund Shares may begin to mirror the liquidity of the Fund’s underlying portfolio holdings, which can be significantly less liquid than Fund Shares. Trading in Fund Shares on the Exchange may be halted due to market conditions or for reasons that, in the view of the Exchange, make trading in Fund Shares inadvisable. In addition, trading in Fund Shares on the Exchange is subject to trading halts caused by extraordinary market volatility pursuant to the Exchange’s “circuit breaker” rules. There can be no assurance that the requirements of the Exchange necessary to maintain the listing of the Fund will continue to be met or will remain unchanged.

Roundhill Ether WeeklyPay™ ETF | U.S. GOVERNMENT SECURITIES RISK  
Prospectus [Line Items]  
Risk [Text Block]

U.S. GOVERNMENT SECURITIES RISK. U.S. government securities are subject to interest rate risk but generally do not involve the credit risks associated with investments in other types of debt securities. As a result, the yields available from U.S. government securities are generally lower than the yields available from other debt securities. U.S. government securities are guaranteed only as to the timely payment of interest and the payment of principal when held to maturity.

Roundhill Ether WeeklyPay™ ETF | VALUATION RISK  
Prospectus [Line Items]  
Risk [Text Block]

VALUATION RISK. The Fund may hold securities or other assets that may be valued on the basis of factors other than market quotations. This may occur because the asset or security does not trade on a centralized exchange, or in times of market turmoil or reduced liquidity. There are multiple methods that can be used to value a portfolio holding when market quotations are not readily available. The value established for any portfolio holding at a point in time might differ from what would be produced using a different methodology or if it had been priced using market quotations. Portfolio holdings that are valued using techniques other than market quotations, including “fair valued” assets or securities, may be subject to greater fluctuation in their valuations from one day to the next than if market quotations were used. In addition, there is no assurance that the Fund could sell or close out a portfolio position for the value established for it at any time, and it is possible that the Fund would incur a loss because a portfolio position is sold or closed out at a discount to the valuation established by the Fund at that time. The Fund’s ability to value investments may be impacted by technological issues or errors by pricing services or other third-party service providers.

Roundhill Ether WeeklyPay™ ETF | EQUITY SECURITIES RISK  
Prospectus [Line Items]  
Risk [Text Block]

EQUITY SECURITIES RISK. Equity securities are subject to changes in value, and their values may be more volatile than those of other asset classes. Equity securities prices fluctuate for several reasons, including changes in investors’ perceptions of the financial condition of an issuer or the general condition of the relevant equity market, such as market volatility, or when political or economic events affecting an issuer occur. Common stock prices may be particularly sensitive to rising interest rates, as the cost of capital rises and borrowing costs increase. Common stocks generally subject their holders to more risks than preferred stocks and debt securities because common stockholders’ claims are subordinated to those of holders of preferred stocks and debt securities upon the bankruptcy of the issuer.

Roundhill Ether WeeklyPay™ ETF | SWAP AGREEMENTS RISK  
Prospectus [Line Items]  
Risk [Text Block]

SWAP AGREEMENTS RISK. The Fund will utilize swap agreements to derive its exposure to shares of the Ether ETF. Swap agreements may involve greater risks than direct investment in securities as they may be leveraged and are subject to credit risk, counterparty risk and valuation risk. A swap agreement could result in losses if the underlying reference or asset does not perform as anticipated. In addition, many swaps trade over-the-counter and may be considered illiquid. It may not be possible for the Fund to liquidate a swap position at an advantageous time or price, which may result in significant losses.

Roundhill Ether WeeklyPay™ ETF | NEW FUND RISK  
Prospectus [Line Items]

NEW FUND RISK. The Fund is a recently organized investment company with a limited operating history. As a result, prospective investors have a limited track record or history on which to base their investment decision.

Roundhill Ether WeeklyPay™ ETF | REGULATED INVESTMENT COMPANY TAX RISKS  
Prospectus [Line Items]  
Risk [Text Block]

REGULATED INVESTMENT COMPANY TAX RISKS. The Fund intends to qualify annually and to elect to be treated as a regulated investment company under the Internal Revenue Code of 1986, as amended (the “Code”). To qualify for the favorable U.S. federal income tax treatment generally accorded to regulated investment companies, the Fund must, among other things, (i) derive in each taxable year at least 90% of its gross income from dividends, interest, payments with respect to securities loans and gains from the sale or other disposition of stock, securities or foreign currencies or other income derived with respect to its business of investing in such stock, securities or currencies, or net income derived from interests in certain publicly traded partnerships; (ii) diversify its holdings so that, at the end of each quarter of the taxable year, (a) at least 50% of the market value of the Fund’s assets is represented by cash and cash items (including receivables), U.S. government securities, the securities of other regulated investment companies and other securities, with such other securities of any one issuer generally limited for the purposes of this calculation to an amount not greater than 5% of the value of the Fund’s total assets and not greater than 10% of the outstanding voting securities of such issuer, and (b) not more than 25% of the value of its total assets is invested in the securities (other than U.S. government securities or the securities of other regulated investment companies) of any one issuer, or two or more issuers which the Fund controls which are engaged in the same, similar or related trades or businesses, or the securities of one or more of certain publicly traded partnerships; and (iii) distribute at least 90% of its investment company taxable income (which includes, among other items, dividends, interest and net short-term capital gains in excess of net long-term capital losses) and at least 90% of its net tax-exempt interest income each taxable year. There are certain exceptions for failure to qualify if the failure is for reasonable cause or is de minimis, and certain corrective action is taken and certain tax payments are made by the Fund.

 

If the Fund were to fail to meet the qualifying income test or asset diversification test and fail to qualify as a RIC, it would be taxed in the same manner as an ordinary corporation, and distributions to its shareholders would not be deductible by the Fund in computing its taxable income, which would adversely affect the Fund’s performance.

Roundhill Ether WeeklyPay™ ETF | LARGE SHAREHOLDER RISK  
Prospectus [Line Items]  
Risk [Text Block]

LARGE SHAREHOLDER RISK. Certain shareholders, including affiliated funds advised by the Adviser, may from time to time own a significant portion of the Fund’s shares. In addition, a third-party investor, the Adviser or an affiliate of the Adviser (“Affiliate”), an authorized participant, a market maker, or another entity may invest in the Fund and hold its investment for a limited period solely to facilitate the commencement of the Fund or to help the Fund achieve a specified size or scale. There can be no assurance that any large shareholder will not redeem its investment, that the size of the Fund will be maintained at such levels, or that the Fund will continue to meet applicable listing requirements. Redemptions by large shareholders could have a significant negative impact on the Fund. In addition, transactions by large shareholders may account for a large percentage of the trading volume on the Fund’s listing exchange and may, therefore, have a material upward or downward effect on the market price of the shares.

 

To the extent that a significant percentage of the Fund’s shares are owned or controlled by a small number of account shareholders (or a single account shareholder), including funds or accounts over which the Adviser or an Affiliate has investment discretion, the Fund is subject to the risk that those shareholders may purchase or redeem Fund shares in significant amounts rapidly or unexpectedly, including as a result of an asset allocation decision made by the Adviser or an Affiliate. This may adversely affect the Fund’s performance if the Adviser is forced to sell portfolio securities or invest cash when it would not otherwise choose to do so. Redemptions of a large number of shares may affect the liquidity of the Fund’s portfolio, increase the Fund’s transaction costs, and accelerate the realization of taxable income and/or gains. In addition, a large redemption could result in the Fund’s current expenses being allocated over a smaller asset base, leading to an increase in the Fund’s gross expense ratio. Large purchases of the Fund’s shares may also adversely affect the Fund’s performance to the extent that the Fund is delayed in investing new cash or otherwise maintains a larger cash position than it ordinarily would, particularly if the Fund accepts cash for an order for the purchase of creation units of the Fund’s shares.

Roundhill Ether WeeklyPay™ ETF | ETHER ETF INVESTING RISKS  
Prospectus [Line Items]  
Risk [Text Block]

ETHER ETF INVESTING RISKS. The Fund will have significant exposure to the Ether ETF through its investments in shares of the Ether ETF and swap agreements that utilize the Ether ETF as the reference asset. Accordingly, the Fund will subject to the risks of the Ether ETF, set forth below. In addition to these risks, the Ether ETF is also subject to the following risks to which the Fund is also subject, which are described within the section entitled “Principal Risks”: Market Risk, Asset Class Risk, Concentration Risk, Current Market Conditions Risk, Cybersecurity Risk, Equity Securities Risk, Operational Risk and Structural ETF Risk.

 

ETHER RISK. Ether is subject to significant volatility, rapid price fluctuations and uncertainty. While ether has experienced substantial growth in institutional adoption, regulatory recognition and technological maturity, its value remains influenced by market sentiment, speculative investment activities, macroeconomic factors and ongoing technological developments rather than purely traditional fundamental analysis. Ethereum is an evolving blockchain platform that continues to undergo substantial upgrades, such as the transition from Proof-of-Work to Proof-of-Stake (Ethereum 2.0 or the “Merge”) and the ongoing rollout of scalability improvements (including Layer 2 solutions such as rollups). These complex technological upgrades are intended to improve Ethereum’s scalability, security, transaction throughput, energy efficiency and usability. However, each significant update introduces risks including technical vulnerabilities, potential software flaws, delays in development, operational disruptions or unintended economic impacts, any of which could negatively affect investor confidence, the adoption of the Ethereum blockchain or ether’s valuation. The regulatory environment for ether and the Ethereum blockchain remains uncertain and varied globally. While certain jurisdictions have provided increased regulatory clarity and oversight, significant regulatory risks persist. Unanticipated regulatory actions, including enforcement actions, reclassification of ether’s regulatory status (such as a security versus commodity) or significant policy changes, could materially impact ether’s value and liquidity. Investors should remain aware that shifts in regulatory classification or compliance requirements may adversely impact the viability, market perception or utility of ether. The Ethereum ecosystem relies heavily on smart contracts, computer code deployed on the Ethereum blockchain capable of automating financial transactions, asset management and decentralized application (dApp) functionalities. While smart contracts enable substantial innovation, they remain vulnerable to coding errors, exploitation, hacks and manipulation. Past security breaches involving decentralized finance (DeFi) platforms, decentralized exchanges and smart contract-based projects have led to significant financial losses, adversely affecting market sentiment, investor confidence and ether’s valuation. Competition from other blockchain networks, sometimes referred to as “Ethereum alternatives” or “Layer 1 competitors,” remains robust. Networks offering potentially superior scalability, lower transaction fees, enhanced privacy or specific technical advantages, such as Solana, Avalanche, Cardano, Polkadot and others, continue to attract users, developers and investors. Successful adoption and growth of competing blockchain ecosystems could limit Ethereum’s market share, ecosystem development and thus negatively impact ether’s long-term valuation. Furthermore, the Ethereum network faces potential governance risks. Decisions regarding protocol upgrades, network policies, or operational changes depend on community consensus among diverse stakeholders, including core developers, validators, decentralized autonomous organizations (DAOs) and other influential actors. Disagreements or governance failures within the Ethereum community could result in contentious blockchain forks, fragmentation of resources, diminished market confidence or value dilution.

 

CUSTODY RISK. Security breaches, computer malware and computer hacking attacks have been a prevalent concern in relation to digital assets. The ether held by the Ether ETF’s custodian will likely be an appealing target to hackers or malware distributors seeking to destroy, damage or steal the Ether ETF’s ether. To the extent that the Ether ETF and its service providers are unable to identify and mitigate or stop new security threats or otherwise adapt to technological changes in the digital asset industry, the Ether ETF’s ether may be subject to theft, loss, destruction or other attack. The Ether ETF and its sponsor and service providers have put security procedures in place to prevent such theft, loss or destruction, including but not limited to, offline storage, or cold storage, multiple encrypted private key “shards” and other measures. Nevertheless, the security procedures cannot guarantee the prevention of any loss due to a security breach, software defect or act of God that may be borne by the Ether ETF and the security procedures may not protect against all errors, software flaws or other vulnerabilities in the Ether ETF’s technical infrastructure, which could result in theft, loss or damage of its assets. The Ether ETF does not control the operations of its service providers or their implementation of such security procedures, and there can be no assurance that such security procedures will actually work as designed or prove to be successful in safeguarding the Ether ETF’s assets against all possible sources of theft, loss or damage. Assets not held in cold storage, such as assets held in a trading account, may be more vulnerable to security breach, hacking or loss than assets held in cold storage. Furthermore, assets held in a trading account are held on an omnibus rather than segregated basis, which creates greater risk of loss. The security procedures and operational infrastructure may be breached due to the actions of outside parties, error or malfeasance of an employee of the Ether ETF’s service providers, and, as a result, an unauthorized party may obtain access to the Ether ETF’s account at the custodian where its ether is held, the relevant private keys (and therefore ether) or other data or property of the Ether ETF. Additionally, outside parties may attempt to fraudulently induce employees of the Ether ETF or its service providers to disclose sensitive information in order to gain access to the Ether ETF’s infrastructure. As the techniques used to obtain unauthorized access, disable or degrade service, or sabotage systems change frequently, or may be designed to remain dormant until a predetermined event and often are not recognized until launched against a target, the Ether ETF and its service providers may be unable to anticipate these techniques or implement adequate preventative measures.

 

DIGITAL ASSET TRADING PLATFORMS RISK. Digital asset trading platforms remain relatively new and vary significantly in terms of regulation, transparency, operational stability and compliance standards. While certain prominent trading platforms, particularly those based in the United States, have substantially improved transparency, compliance, and regulatory adherence, many platforms still operate internationally or offshore with significantly less stringent oversight. Platforms located outside the United States may be subject to minimal or inconsistent regulatory enforcement and often do not provide sufficient public information regarding their management structure, ownership, financial stability, cybersecurity practices, or compliance controls. Despite increased institutional involvement, enhanced security measures, and more standardized operating practices adopted by leading platforms, digital asset exchanges continue to be vulnerable to cybersecurity threats, hacking incidents, fraudulent activities, operational disruptions and other technical risks. High-profile failures, breaches or shutdowns of major trading platforms or custodians—such as those arising from fraud, cybersecurity incidents, regulatory enforcement actions or insolvency—can significantly reduce investor confidence, increase market volatility and potentially trigger contagion effects across the digital asset ecosystem. Regulatory developments and enforcement actions continue to shape the landscape in which digital asset platforms operate. Recent regulatory scrutiny has heightened globally, particularly in jurisdictions with substantial trading volumes, such as the United States, Europe and Asia. Increased regulatory oversight, while potentially positive for market stability in the long run, can create short-term disruption, reduce liquidity, prompt platform closures or alter business models substantially, thereby affecting the prices of digital assets, including ether. Investors should be aware that trading or custodying ether on less transparent or poorly regulated platforms increases the risk of losing access to digital assets due to platform insolvency, hacking incidents, regulatory intervention or operational failure. Although improvements have been made, the digital asset marketplace remains inherently riskier than traditional financial markets, and investors may have limited recourse if a digital asset trading platform fails or is compromised.

 

IRREVOCABILITY OF TRANSACTIONS RISK. Ether transactions are typically not reversible without the consent and active participation of the recipient of the transaction. Once a transaction has been verified and recorded in a block that is added to the Ethereum blockchain, an incorrect transfer or theft of ether generally will not be reversible, and the Ether ETF may not be capable of seeking compensation for any such transfer or theft. It is possible that, through computer or human error, or through theft or other criminal action, the Ether ETF’s ether could be transferred from the Ether ETF’s account at its custodian in incorrect amounts or to unauthorized third parties, or to uncontrolled accounts.

 

VOLATILITY RISK. The price of ether remains highly volatile and subject to significant price fluctuations. While recent increases in institutional adoption, clearer regulatory frameworks and broader market acceptance have contributed to greater stability relative to earlier periods, the price of ether continues to be influenced by rapid shifts in market sentiment, regulatory developments, macroeconomic conditions, technological advancements and unforeseen events. The market price of ether has historically experienced dramatic highs and lows over short periods, often with limited or no identifiable catalyst. Given the evolving nature of digital asset markets, price volatility may be amplified by external factors such as changes in global financial markets, geopolitical events, regulatory enforcement actions or significant technological or security incidents. Furthermore, speculative trading, leveraged positions and derivatives markets tied to ether continue to contribute to potential volatility. Investors should remain aware that sudden, substantial price movements may occur at any time, potentially leading to significant losses. Consequently, investments linked directly or indirectly to ether, including the Ether ETF, may experience heightened volatility compared to traditional investment products.

NON-DIVERSIFICATION RISK. As a “non-diversified” fund, the Fund may hold a smaller number of portfolio securities than many other funds. To the extent the Fund invests in a relatively small number of issuers, a decline in the market value of a particular security held by the Fund may affect its value more than if it invested in a larger number of issuers. The value of the Fund Shares may be more volatile than the values of shares of more diversified funds.

Roundhill Gold WeeklyPay™ ETF | MARKET RISK  
Prospectus [Line Items]  
Risk [Text Block]

MARKET RISK. Market risk is the risk that a particular investment, or Fund Shares in general, may fall in value. Securities are subject to market fluctuations caused by real or perceived adverse economic, political, and regulatory factors or market developments, changes in interest rates, disruptions to trade, impositions of tariffs and perceived trends in securities prices. Fund Shares could decline in value or underperform other investments. In addition, local, regional or global events such as war, acts of terrorism, market manipulation, government defaults, government shutdowns, regulatory actions, political changes, diplomatic developments, the imposition of sanctions and other similar measures, spread of infectious diseases or other public health issues, recessions, natural disasters, or other events could have a significant negative impact on the Fund and its investments. Any of such circumstances could have a materially negative impact on the value of Fund Shares, the liquidity of an investment, and may result in increased market volatility. During any such events, Fund Shares may trade at increased premiums or discounts to their net asset value, the bid/ask spread on Fund Shares may widen and the returns on investment may fluctuate.

Roundhill Gold WeeklyPay™ ETF | LIQUIDITY RISK  
Prospectus [Line Items]  
Risk [Text Block]

LIQUIDITY RISK. The market for swap agreements that reference the Gold ETF shares may be subject to periods of illiquidity. During such times it may be difficult or impossible to buy or sell a position at the desired price. Market disruptions or volatility can also make it difficult to find a counterparty willing to transact at a reasonable price and sufficient size. Illiquid markets may cause losses, which could be significant. The large size of the positions which the Fund may acquire increases the risk of illiquidity, may make its positions more difficult to liquidate, and may increase the losses incurred while trying to do so. Such large positions also may impact the price of swap agreements on the Gold ETF shares.

Roundhill Gold WeeklyPay™ ETF | ACTIVE MANAGEMENT RISK  
Prospectus [Line Items]

ACTIVE MANAGEMENT RISK. The Fund is actively-managed and its performance reflects investment decisions that the Adviser and/or Sub-Adviser makes for the Fund. Such judgments about the Fund’s investments may prove to be incorrect. If the investments selected and the strategies employed by the Fund fail to produce the intended results, the Fund could underperform as compared to other funds with similar investment objectives and/or strategies, or could have negative returns.

Roundhill Gold WeeklyPay™ ETF | ACTIVE MARKET RISK

ACTIVE MARKET RISK. Although Fund Shares are listed for trading on the Exchange, there can be no assurance that an active trading market for Fund Shares will develop or be maintained. Fund Shares trade on the Exchange at market prices that may be below, at or above the Fund’s net asset value. Securities, including Fund Shares, are subject to market fluctuations and liquidity constraints that may be caused by such factors as economic, political, or regulatory developments, changes in interest rates, and/or perceived trends in securities prices. Fund Shares could decline in value or underperform other investments.

CONCENTRATION RISK. The Fund is susceptible to an increased risk of loss, including losses due to adverse events that affect the Fund’s investments more than the market as a whole, to the extent that the Fund’s investments are concentrated in instruments or investments that provide exposure to gold.

Roundhill Gold WeeklyPay™ ETF | COUNTERPARTY RISK

COUNTERPARTY RISK. Fund transactions involving a counterparty are subject to the risk that the counterparty will not fulfill its obligation to the Fund. Counterparty risk may arise because of the counterparty’s financial condition (i.e., financial difficulties, bankruptcy, or insolvency), market activities and developments, or other reasons, whether foreseen or not. A counterparty’s inability to fulfill its obligation may result in significant financial loss to the Fund. The Fund may be unable to recover its investment from the counterparty or may obtain a limited recovery, and/or recovery may be delayed.

Roundhill Gold WeeklyPay™ ETF | CURRENT MARKET CONDITIONS RISK  
Prospectus [Line Items]  
Risk [Text Block]

CURRENT MARKET CONDITIONS RISK. Current market conditions risk is the risk that a particular investment, or Fund Shares in general, may fall in value due to current market conditions. As a means to fight inflation, which remains at elevated levels, the Federal Reserve and certain foreign central banks have raised interest rates; however, the Federal Reserve has recently lowered interest rates and may continue to do so. U.S. regulators have proposed several changes to market and issuer regulations which would directly impact the Fund, and any regulatory changes could adversely impact the Fund’s ability to achieve its investment strategies or make certain investments. Recent and potential future bank failures could result in disruption to the broader banking industry or markets generally and reduce confidence in financial institutions and the economy as a whole, which may also heighten market volatility and reduce liquidity. Additionally, challenges in commercial real estate markets, including rising interest rates, declining valuations and increasing vacancies, could have a broader impact on financial markets. The ongoing adversarial political climate in the United States, as well as political and diplomatic events both domestic and abroad, have and may continue to have an adverse impact the U.S. regulatory landscape, markets and investor behavior, which could have a negative impact on the Fund’s investments and operations. The change in administration resulting from the 2024 United States national elections could result in significant impacts to international trade relations, tax and immigration policies, and other aspects of the national and international political and financial landscape, which could affect, among other things, inflation and the securities markets generally. Other unexpected political, regulatory and diplomatic events within the U.S. and abroad may affect investor and consumer confidence and may adversely impact financial markets and the broader economy. For example, ongoing armed conflicts between Russia and Ukraine in Europe and among Israel, Iran, Hamas and other militant groups in the Middle East, have caused and could continue to cause significant market disruptions and volatility within the markets in Russia, Europe, the Middle East and the United States. The hostilities and sanctions resulting from those hostilities have and could continue to have a significant impact on certain Fund investments as well as Fund performance and liquidity. The economies of the United States and its trading partners, as well as the financial markets generally, may be adversely impacted by trade disputes, including the imposition of tariffs, and other matters. For example, the United States has imposed trade barriers and restrictions on China. In addition, the Chinese government is engaged in a longstanding dispute with Taiwan, continually threatening an invasion. If the political climate between the United States and China does not improve or continues to deteriorate, if China were to attempt invading Taiwan, or if other geopolitical conflicts develop or worsen, economies, markets and individual securities may be adversely affected, and the value of the Fund’s assets may go down. A public health crisis and the ensuing policies enacted by governments and central banks may cause significant volatility and uncertainty in global financial markets, negatively impacting global growth prospects. As the COVID-19 global pandemic illustrated, such events may affect certain geographic regions, countries, sectors and industries more significantly than others. Advancements in technology may also adversely impact markets and the overall performance of the Fund. For instance, the economy may be significantly impacted by the advanced development and increased regulation of artificial intelligence. Additionally, cyber security breaches of both government and non-government entities could have negative impacts on infrastructure and the ability of such entities, including the Fund, to operate properly. These events, and any other future events, may adversely affect the prices and liquidity of the Fund’s portfolio investments and could result in disruptions in the trading markets.

Roundhill Gold WeeklyPay™ ETF | CYBERSECURITY RISK  
Prospectus [Line Items]  
Risk [Text Block]

CYBERSECURITY RISK. Failures or breaches of the electronic systems of the Fund, the Fund’s adviser, sub-adviser, distributor and other service providers, market makers, Authorized Participants or the issuers of securities in which the Fund invests have the ability to cause disruptions, negatively impact the Fund’s business operations and/or potentially result in financial losses to the Fund and its shareholders. While the Fund has established business continuity plans and risk management systems seeking to address system breaches or failures, there are inherent limitations in such plans and systems. Furthermore, the Fund cannot control the cybersecurity plans and systems of the Fund’s other service providers, market makers, Authorized Participants or issuers of securities in which the Fund invests.

Roundhill Gold WeeklyPay™ ETF | DEBT SECURITIES RISK  
Prospectus [Line Items]  
Risk [Text Block]

DEBT SECURITIES RISK. Investments in debt securities subject the holder to the credit risk of the issuer. Credit risk refers to the possibility that the issuer or other obligor of a security will not be able or willing to make payments of interest and principal when due. Generally, the value of debt securities will change inversely with changes in interest rates. To the extent that interest rates rise, certain underlying obligations may be paid off substantially slower than originally anticipated and the value of those securities may fall sharply. During periods of falling interest rates, the income received by the Fund may decline. If the principal on a debt security is prepaid before expected, the prepayments of principal may have to be reinvested in obligations paying interest at lower rates. Debt securities generally do not trade on a securities exchange making them generally less liquid and more difficult to value than common stock.

Roundhill Gold WeeklyPay™ ETF | DERIVATIVES RISK  
Prospectus [Line Items]  
Risk [Text Block]

DERIVATIVES RISK. The use of derivative instruments involves risks different from, or possibly greater than, the risks associated with investing directly in securities and other traditional investments. These risks include: (i) the risk that the counterparty to a derivative transaction may not fulfill its contractual obligations; (ii) risk of mispricing or improper valuation; and (iii) the risk that changes in the value of the derivative may not correlate perfectly with the underlying asset. Derivative prices are highly volatile and may fluctuate substantially during a short period of time. Such prices are influenced by numerous factors that affect the markets, including, but not limited to: changing supply and demand relationships; government programs and policies; national and international political and economic events, changes in interest rates, inflation and deflation and changes in supply and demand relationships. Trading derivative instruments involves risks different from, or possibly greater than, the risks associated with investing directly in securities. Derivative contracts ordinarily have leverage inherent in their terms. The use of leverage may cause the Fund to liquidate portfolio positions when it would not be advantageous to do so in order to satisfy its obligations or to meet regulatory or contractual requirements for derivatives. The use of derivatives can magnify potential for gain or loss and, therefore, amplify the effects of market volatility on share price.

Roundhill Gold WeeklyPay™ ETF | DISTRIBUTION TAX RISK  
Prospectus [Line Items]  
Risk [Text Block]

DISTRIBUTION TAX RISK. The Fund currently expects to make distributions on a weekly basis. Such frequent distributions may expose investors to increased tax liabilities. However, these distributions may exceed the Fund’s income and gains for the Fund’s taxable year. Distributions in excess of the Fund’s current and accumulated earnings and profits will be treated as a return of capital. A return of capital distribution generally will not be taxable but will reduce the shareholder’s cost basis and will result in a higher capital gain or lower capital loss when those Fund Shares on which the distribution was received are sold. Once a Fund shareholder’s cost basis is reduced to zero, further distributions will be treated as capital gain if the Fund shareholder holds Fund Shares as capital assets. Additionally, any capital returned through distributions will be distributed after payment of Fund fees and expenses. Because a portion of the Fund’s distributions may consist of return of capital, the Fund may not be an appropriate investment for investors who do not want their principal investment in the Fund to decrease over time or who do not wish to receive return of capital in a given period. In the event that a shareholder purchases Fund Shares shortly before a distribution by the Fund, the entire distribution may be taxable to the shareholder even though a portion of the distribution effectively represents a return of the purchase price.

Roundhill Gold WeeklyPay™ ETF | ETF RISK  
Prospectus [Line Items]  
Risk [Text Block]

ETF RISK. The Fund may invest in ETFs. The value of an ETF held by the Fund will fluctuate over time based on fluctuations in the values of the assets held by the ETF, which may be affected by changes in general economic conditions, expectations for future growth and profits, interest rates and the supply and demand for those assets. When the Fund invests in an ETF, it will bear a proportionate share of the ETF’s expenses. Brokerage, tax and other expenses may negatively impact the performance of the ETF and, in turn, the value of the Fund Shares. An ETF that tracks an index may not exactly match the performance of the index due to cash drag, differences between the portfolio of the ETF and the components of the index, expenses and other factors.

Roundhill Gold WeeklyPay™ ETF | INFLATION RISK  
Prospectus [Line Items]  
Risk [Text Block]

INFLATION RISK. Inflation risk is the risk that the value of assets or income from investments will be less in the future as inflation decreases the value of money. As inflation increases, the present value of the Fund’s assets and distributions may decline. This risk is more prevalent with respect to fixed income securities held by the Fund.

Roundhill Gold WeeklyPay™ ETF | Interest Rate Risk [Member]  
Prospectus [Line Items]  
Risk [Text Block]

INTEREST RATE RISK. Interest rate risk is the risk that the value of the debt securities in the Fund’s portfolio will decline because of rising market interest rates. Interest rate risk is generally lower for shorter term debt securities and higher for longer-term debt securities. Duration is a reasonably accurate measure of a debt security’s price sensitivity to changes in interest rates and a common measure of interest rate risk. Duration measures a debt security’s expected life on a present value basis, taking into account the debt security’s yield, interest payments and final maturity. In general, duration represents the expected percentage change in the value of a security for an immediate 1% change in interest rates. For example, the price of a debt security with a three-year duration would be expected to drop by approximately 3% in response to a 1% increase in interest rates. Therefore, prices of debt securities with shorter durations tend to be less sensitive to interest rate changes than debt securities with longer durations. As the value of a debt security changes over time, so will its duration.

Roundhill Gold WeeklyPay™ ETF | LEGISLATION AND LITIGATION RISK  
Prospectus [Line Items]  
Risk [Text Block]

LEGISLATION AND LITIGATION RISK. Legislation or litigation that affects the value of assets or securities held by the Fund may reduce the value of the Fund. From time to time, various legislative initiatives are proposed that may have a negative impact on certain assets or securities in which the Fund invests. In addition, litigation regarding any of the assets or securities owned by the Fund may negatively impact the value of the Shares. Such legislation or litigation may cause the Fund to lose value or may result in higher portfolio turnover if the Adviser determines to sell such a holding.

Roundhill Gold WeeklyPay™ ETF | LEVERAGE RISK  
Prospectus [Line Items]  
Risk [Text Block]

LEVERAGE RISK. The Fund obtains investment exposure in excess of its net assets by utilizing leverage and may lose more money in market conditions that are adverse to its investment objectives than a fund that does not utilize leverage. An investment in the Fund is exposed to the risk that a decline in the weekly performance of shares of the Gold ETF will be magnified. This means that an investment in the Fund will be reduced by an amount equal to 1.2% for every 1% weekly decline in the market value of the Gold ETF shares, not including the costs of financing leverage and other operating expenses, which would further reduce its value. The Fund could theoretically lose an amount greater than its net assets in the event the market value of the Gold ETF shares decline more than 83.33% over a calendar week. Leverage will also have the effect of magnifying any differences in the Fund’s correlation with the Gold ETF shares.

Roundhill Gold WeeklyPay™ ETF | MONEY MARKET INSTRUMENTS RISK  
Prospectus [Line Items]  
Risk [Text Block]

MONEY MARKET INSTRUMENTS RISK. The value of money market instruments may be affected by changing interest rates and by changes in the credit ratings of the investments. If a significant amount of the Fund’s assets are invested in money market instruments, it will be more difficult for the Fund to achieve its investment objectives. An investment in a money market fund is not insured or guaranteed by the FDIC or any other government agency. It is possible to lose money by investing in a money market fund.

Roundhill Gold WeeklyPay™ ETF | OPERATIONAL RISK  
Prospectus [Line Items]  
Risk [Text Block]

OPERATIONAL RISK. The Fund is subject to risks arising from various operational factors, including, but not limited to, human error, processing and communication errors, errors of the Fund’s service providers, counterparties or other third-parties, failed or inadequate processes and technology or systems failures. The Fund relies on third-parties for a range of services, including custody. Any delay or failure relating to engaging or maintaining such service providers may affect the Fund’s ability to meet its investment objectives. Although the Fund and the Adviser seek to reduce these operational risks through controls and procedures, there is no way to completely protect against such risks.

Roundhill Gold WeeklyPay™ ETF | SPECIAL TAX RISK  
Prospectus [Line Items]  
Risk [Text Block]

SPECIAL TAX RISK. The Fund intends to qualify as a “regulated investment company” (“RIC”), however, the federal income tax treatment of certain aspects of the proposed operations of the Fund are not entirely clear. This includes the tax aspects of the Fund’s options strategy, the possible application of the “straddle” rules, and various loss limitation provisions of the Internal Revenue Code of 1986, as amended (the “Code”). If, in any year, the Fund fails to qualify as a RIC under the applicable tax laws, the Fund would be taxed as an ordinary corporation.

 

The Fund intends to treat the income it derives from gains on swaps referencing the Gold ETF as “qualifying income” for purposes of the RIC qualification rules under Subchapter M of the Code. It has adopted this position in reliance on an opinion obtained from counsel that income from such investments should constitute “qualifying income,” as shares of the Gold ETF constitute “securities” under Section 2(a)(36) of the 1940 Act. However, this opinion is not binding upon the Internal Revenue Service (“IRS”). If the IRS were to successfully assert that the Fund’s income from such investments was not “qualifying income,” the Fund may fail to qualify as a RIC under Subchapter M if over 10% of its gross income was derived from these investments. If the Fund failed to qualify as a RIC, it would be subject to federal and state income tax on all of its taxable income at regular corporate tax rates with no deduction for any distributions paid to shareholders, which would significantly adversely affect the returns to, and could cause substantial losses for, Fund shareholders.

 

To maintain its status as a RIC, the Fund must distribute 90% of its investment company taxable income annually. In addition, to avoid a non-deductible excise tax, the Fund must distribute 98% of its ordinary income and 98.2% of its capital gain net income. Separately, depending upon the circumstances, sales to fund redemptions could cause the Fund to recognize income that the Fund is required to distribute to maintain the Fund’s RIC status and avoid the excise tax. Funding such distributions could require additional sales, which could require more distributions and affect the projected performance of the Fund. Alternatively, if the Fund only makes distributions to maintain its RIC status and becomes subject to the excise tax, that could also affect the projected performance of the Fund. In either case, the assets sold to fund redemptions, distributions or pay the excise tax will not be available to assist the Fund in meeting its investment objectives.

 

In the event that a shareholder purchases shares of the Fund shortly before a distribution by the Fund, the entire distribution may be taxable to the shareholder even though a portion of the distribution effectively represents a return of the purchase price.

Roundhill Gold WeeklyPay™ ETF | STRUCTURAL ETF RISKS  
Prospectus [Line Items]  
Risk [Text Block]

STRUCTURAL ETF RISKS. The Fund is an ETF. Accordingly, it is subject to certain risks associated with its unique structure.

 

Market Participants Risk. Only an Authorized Participant may engage in creation or redemption transactions directly with the Fund, and none of those Authorized Participants is obligated to engage in creation and/or redemption transactions. The Fund has a limited number of institutions that may act as Authorized Participants on an agency basis (i.e., on behalf of other market participants). To the extent that Authorized Participants exit the business or are unable to proceed with creation or redemption orders with respect to the Fund and no other Authorized Participant is able to step forward to create or redeem, Fund Shares may be more likely to trade at a premium or discount to NAV and possibly face trading halts or delisting. The Fund may also rely on a small number of third-party market makers to provide a market for the purchase and sale of Fund Shares but such market makers are under no obligation to do so. Decisions by Authorized Participants or market makers to reduce their role or step away from these activities in times of market stress could inhibit the effectiveness of the arbitrage process in maintaining the relationship between the underlying values of the Fund’s portfolio securities and the Fund’s market price. Any trading halt or other problem relating to the trading activity of these market makers or any issues disrupting the Authorized Participants’ ability to proceed with creation and/or redemption orders could result in a dramatic change in the spread between the Fund’s net asset value and the price at which Fund Shares are trading on the Exchange, which could result in a decrease in value of Fund Shares. This reduced effectiveness could result in Fund Shares trading at a premium or discount to net asset value and also in greater than normal intraday bid-ask spreads Fund Shares.

 

Cash Transactions Risk. The Fund currently expects to effect a significant portion of its creations and redemptions for cash, rather than in-kind securities. Paying redemption proceeds in cash rather than through in-kind delivery of portfolio securities may require the Fund to dispose of or sell portfolio securities or other assets at an inopportune time to obtain the cash needed to meet redemption orders. This may cause the Fund to sell a security and recognize a capital gain or loss that might not have been incurred if it had made a redemption in-kind. As a result, the Fund may pay out higher or lower annual capital gains distributions than ETFs that redeem in-kind. The use of cash creations and redemptions may also cause the Fund’s Shares to trade in the market at greater bid-ask spreads or greater premiums or discounts to the Fund’s NAV. Furthermore, the Fund may not be able to execute cash transactions for creation and redemption purposes at the same price used to determine the Fund’s NAV. To the extent that the maximum additional charge for creation or redemption transactions is insufficient to cover the execution shortfall, the Fund’s performance could be negatively impacted.

 

Costs of Buying and Selling Fund Shares. Due to the costs of buying or selling Fund Shares, including brokerage commissions imposed by brokers and bid/ask spreads, frequent trading of Fund Shares may significantly reduce investment results and an investment in Fund Shares may not be advisable for investors who anticipate regularly making small investments.

 

Premium/Discount Risk. As with all ETFs, Fund Shares may be bought and sold in the secondary market at market prices. The trading prices of Fund Shares in the secondary market may differ from the Fund’s daily net asset value per share and there may be times when the market price of the shares is more than the net asset value per share (premium) or less than the net asset value per share (discount). If a shareholder purchases Fund Shares at a time when the market price is at a premium to the net asset value or sells Fund Shares at a time when the market price is at a discount to the net asset value, the shareholder may pay more for, or receive less than, the underlying value of the Fund Shares, respectively. This risk is heightened in times of market volatility or periods of steep market declines.

 

Trading Risks. Although Fund Shares are listed for trading on the Exchange and may be traded on U.S. exchanges other than the Exchange, there can be no assurance that Fund Shares will trade with any volume, or at all, on any stock exchange. In stressed market conditions, the liquidity of Fund Shares may begin to mirror the liquidity of the Fund’s underlying portfolio holdings, which can be significantly less liquid than Fund Shares. Trading in Fund Shares on the Exchange may be halted due to market conditions or for reasons that, in the view of the Exchange, make trading in Fund Shares inadvisable. In addition, trading in Fund Shares on the Exchange is subject to trading halts caused by extraordinary market volatility pursuant to the Exchange’s “circuit breaker” rules. There can be no assurance that the requirements of the Exchange necessary to maintain the listing of the Fund will continue to be met or will remain unchanged.

Roundhill Gold WeeklyPay™ ETF | U.S. GOVERNMENT SECURITIES RISK  
Prospectus [Line Items]  
Risk [Text Block]

U.S. GOVERNMENT SECURITIES RISK. U.S. government securities are subject to interest rate risk but generally do not involve the credit risks associated with investments in other types of debt securities. As a result, the yields available from U.S. government securities are generally lower than the yields available from other debt securities. U.S. government securities are guaranteed only as to the timely payment of interest and the payment of principal when held to maturity.

Roundhill Gold WeeklyPay™ ETF | VALUATION RISK  
Prospectus [Line Items]  
Risk [Text Block]

VALUATION RISK. The Fund may hold securities or other assets that may be valued on the basis of factors other than market quotations. This may occur because the asset or security does not trade on a centralized exchange, or in times of market turmoil or reduced liquidity. There are multiple methods that can be used to value a portfolio holding when market quotations are not readily available. The value established for any portfolio holding at a point in time might differ from what would be produced using a different methodology or if it had been priced using market quotations. Portfolio holdings that are valued using techniques other than market quotations, including “fair valued” assets or securities, may be subject to greater fluctuation in their valuations from one day to the next than if market quotations were used. In addition, there is no assurance that the Fund could sell or close out a portfolio position for the value established for it at any time, and it is possible that the Fund would incur a loss because a portfolio position is sold or closed out at a discount to the valuation established by the Fund at that time. The Fund’s ability to value investments may be impacted by technological issues or errors by pricing services or other third-party service providers.

Roundhill Gold WeeklyPay™ ETF | EQUITY SECURITIES RISK  
Prospectus [Line Items]  
Risk [Text Block]

EQUITY SECURITIES RISK. Equity securities are subject to changes in value, and their values may be more volatile than those of other asset classes. Equity securities prices fluctuate for several reasons, including changes in investors’ perceptions of the financial condition of an issuer or the general condition of the relevant equity market, such as market volatility, or when political or economic events affecting an issuer occur. Common stock prices may be particularly sensitive to rising interest rates, as the cost of capital rises and borrowing costs increase. Common stocks generally subject their holders to more risks than preferred stocks and debt securities because common stockholders’ claims are subordinated to those of holders of preferred stocks and debt securities upon the bankruptcy of the issuer.

Roundhill Gold WeeklyPay™ ETF | SWAP AGREEMENTS RISK  
Prospectus [Line Items]  
Risk [Text Block]

SWAP AGREEMENTS RISK. The Fund will utilize swap agreements to derive its exposure to shares of the Gold ETF. Swap agreements may involve greater risks than direct investment in securities as they may be leveraged and are subject to credit risk, counterparty risk and valuation risk. A swap agreement could result in losses if the underlying reference or asset does not perform as anticipated. In addition, many swaps trade over-the-counter and may be considered illiquid. It may not be possible for the Fund to liquidate a swap position at an advantageous time or price, which may result in significant losses.

Roundhill Gold WeeklyPay™ ETF | REGULATED INVESTMENT COMPANY TAX RISKS  
Prospectus [Line Items]  
Risk [Text Block]

REGULATED INVESTMENT COMPANY TAX RISKS. The Fund intends to qualify annually and to elect to be treated as a regulated investment company under the Internal Revenue Code of 1986, as amended (the “Code”). To qualify for the favorable U.S. federal income tax treatment generally accorded to regulated investment companies, the Fund must, among other things, (i) derive in each taxable year at least 90% of its gross income from dividends, interest, payments with respect to securities loans and gains from the sale or other disposition of stock, securities or foreign currencies or other income derived with respect to its business of investing in such stock, securities or currencies, or net income derived from interests in certain publicly traded partnerships; (ii) diversify its holdings so that, at the end of each quarter of the taxable year, (a) at least 50% of the market value of the Fund’s assets is represented by cash and cash items (including receivables), U.S. government securities, the securities of other regulated investment companies and other securities, with such other securities of any one issuer generally limited for the purposes of this calculation to an amount not greater than 5% of the value of the Fund’s total assets and not greater than 10% of the outstanding voting securities of such issuer, and (b) not more than 25% of the value of its total assets is invested in the securities (other than U.S. government securities or the securities of other regulated investment companies) of any one issuer, or two or more issuers which the Fund controls which are engaged in the same, similar or related trades or businesses, or the securities of one or more of certain publicly traded partnerships; and (iii) distribute at least 90% of its investment company taxable income (which includes, among other items, dividends, interest and net short-term capital gains in excess of net long-term capital losses) and at least 90% of its net tax-exempt interest income each taxable year. There are certain exceptions for failure to qualify if the failure is for reasonable cause or is de minimis, and certain corrective action is taken and certain tax payments are made by the Fund.

 

If the Fund were to fail to meet the qualifying income test or asset diversification test and fail to qualify as a RIC, it would be taxed in the same manner as an ordinary corporation, and distributions to its shareholders would not be deductible by the Fund in computing its taxable income, which would adversely affect the Fund’s performance.

Roundhill Gold WeeklyPay™ ETF | LARGE SHAREHOLDER RISK  
Prospectus [Line Items]  
Risk [Text Block]

LARGE SHAREHOLDER RISK. Certain shareholders, including affiliated funds advised by the Adviser, may from time to time own a significant portion of the Fund’s shares. In addition, a third-party investor, the Adviser or an affiliate of the Adviser (“Affiliate”), an authorized participant, a market maker, or another entity may invest in the Fund and hold its investment for a limited period solely to facilitate the commencement of the Fund or to help the Fund achieve a specified size or scale. There can be no assurance that any large shareholder will not redeem its investment, that the size of the Fund will be maintained at such levels, or that the Fund will continue to meet applicable listing requirements. Redemptions by large shareholders could have a significant negative impact on the Fund. In addition, transactions by large shareholders may account for a large percentage of the trading volume on the Fund’s listing exchange and may, therefore, have a material upward or downward effect on the market price of the shares.

 

To the extent that a significant percentage of the Fund’s shares are owned or controlled by a small number of account shareholders (or a single account shareholder), including funds or accounts over which the Adviser or an Affiliate has investment discretion, the Fund is subject to the risk that those shareholders may purchase or redeem Fund shares in significant amounts rapidly or unexpectedly, including as a result of an asset allocation decision made by the Adviser or an Affiliate. This may adversely affect the Fund’s performance if the Adviser is forced to sell portfolio securities or invest cash when it would not otherwise choose to do so. Redemptions of a large number of shares may affect the liquidity of the Fund’s portfolio, increase the Fund’s transaction costs, and accelerate the realization of taxable income and/or gains. In addition, a large redemption could result in the Fund’s current expenses being allocated over a smaller asset base, leading to an increase in the Fund’s gross expense ratio. Large purchases of the Fund’s shares may also adversely affect the Fund’s performance to the extent that the Fund is delayed in investing new cash or otherwise maintains a larger cash position than it ordinarily would, particularly if the Fund accepts cash for an order for the purchase of creation units of the Fund’s shares.

Roundhill Gold WeeklyPay™ ETF | GOLD ETF INVESTING RISKS  
Prospectus [Line Items]  
Risk [Text Block]

GOLD ETF INVESTING RISKS. The Fund will have significant exposure to the Gold ETF through its investments in shares of the Gold ETF and swap agreements that utilize the Gold ETF as the reference asset. Accordingly, the Fund will subject to the risks of the Gold ETF, set forth below. In addition to these risks, the Gold ETF is also subject to the following risks to which the Fund is also subject, which are described within the section entitled “Principal Risks”: Market Risk, Asset Class Risk, Concentration Risk, Current Market Conditions Risk, Cybersecurity Risk, Equity Securities Risk, Operational Risk and Structural ETF Risk.

 

GOLD RISK. Gold prices are affected by the physical supply of gold from mining and recycling, as well as demand from sectors such as jewelry, technology and central bank purchases. Changes in production levels, mining costs and geopolitical developments in gold-producing countries may materially impact supply. Additionally, gold is often viewed as a hedge against inflation and currency devaluation. Accordingly, changes in interest rates, inflation expectations or monetary policy actions by central banks can significantly affect gold prices. A rise in interest rates may reduce the appeal of gold, which does not produce interest income. Gold is also commonly perceived as a “safe haven” asset during periods of political instability, market stress or global economic downturns. However, there is no guarantee that gold will provide the sought-after returns during such periods. Conversely, during periods of economic expansion or risk-on sentiment, investor demand for gold may diminish, adversely affecting its price. Changes in regulations affecting gold trading or the taxation of precious metals may also affect the market for gold and, therefore, the Gold ETF’s performance. If the value of gold declines, or if the price of gold fails to rise during periods of inflation, currency devaluation or financial stress, the Gold ETF’s investments could underperform or experience significant losses. There is no assurance that gold will maintain its historical role as a store of value or inflation hedge in future market environments.

 

CUSTODY RISK. There is a risk that some or all of the Gold ETF’s gold bars held by its custodian (the “GLD Custodian”) or any subcustodian on behalf of the Gold ETF could be lost, damaged or stolen. Access to the Gold ETF’s gold bars could also be restricted by natural events (such as an earthquake) or human actions (such as a terrorist attack). Any of these events may adversely affect the operations of the Gold ETF and, consequently, cause significant negative consequences with regard to investments linked to the Gold ETF. Shareholders’ recourse against the Gold ETF, the Gold ETF’s trustee (the “GLD Trustee”) and the Gold ETF’s sponsor, under New York law, the GLD Custodian, under English law, and any subcustodians under the law governing their custody operations is limited. The Gold ETF does not insure its gold. The GLD Custodian maintains insurance with regard to its business on such terms and conditions as it considers appropriate which does not cover the full amount of gold. The Gold ETF is not a beneficiary of any such insurance and does not have the ability to dictate the existence, nature or amount of coverage. Therefore, the Gold ETF shareholders cannot be assured that the GLD Custodian will maintain adequate insurance or any insurance with respect to the gold held by the Custodian on behalf of the Gold ETF. In addition, the GLD Custodian and the GLD Trustee do not require any direct or indirect subcustodians to be insured or bonded with respect to their custodial activities or in respect of the gold held by them on behalf of the Gold ETF. Consequently, a loss may be suffered with respect to the Gold ETF’s gold which is not covered by insurance and for which no person is liable in damages.

NON-DIVERSIFICATION RISK. As a “non-diversified” fund, the Fund may hold a smaller number of portfolio securities than many other funds. To the extent the Fund invests in a relatively small number of issuers, a decline in the market value of a particular security held by the Fund may affect its value more than if it invested in a larger number of issuers. The value of the Fund Shares may be more volatile than the values of shares of more diversified funds.

Roundhill High Yield Bond WeeklyPay™ ETF | MARKET RISK  
Prospectus [Line Items]  
Risk [Text Block]

MARKET RISK. Market risk is the risk that a particular investment, or Fund Shares in general, may fall in value. Securities are subject to market fluctuations caused by real or perceived adverse economic, political, and regulatory factors or market developments, changes in interest rates, disruptions to trade, impositions of tariffs and perceived trends in securities prices. Fund Shares could decline in value or underperform other investments. In addition, local, regional or global events such as war, acts of terrorism, market manipulation, government defaults, government shutdowns, regulatory actions, political changes, diplomatic developments, the imposition of sanctions and other similar measures, spread of infectious diseases or other public health issues, recessions, natural disasters, or other events could have a significant negative impact on the Fund and its investments. Any of such circumstances could have a materially negative impact on the value of Fund Shares, the liquidity of an investment, and may result in increased market volatility. During any such events, Fund Shares may trade at increased premiums or discounts to their net asset value, the bid/ask spread on Fund Shares may widen and the returns on investment may fluctuate.

Roundhill High Yield Bond WeeklyPay™ ETF | LIQUIDITY RISK  
Prospectus [Line Items]  
Risk [Text Block]

LIQUIDITY RISK. The market for swap agreements that reference the High Yield Bond ETF shares may be subject to periods of illiquidity. During such times it may be difficult or impossible to buy or sell a position at the desired price. Market disruptions or volatility can also make it difficult to find a counterparty willing to transact at a reasonable price and sufficient size. Illiquid markets may cause losses, which could be significant. The large size of the positions which the Fund may acquire increases the risk of illiquidity, may make its positions more difficult to liquidate, and may increase the losses incurred while trying to do so. Such large positions also may impact the price of swap agreements on the High Yield Bond ETF shares.

Roundhill High Yield Bond WeeklyPay™ ETF | ACTIVE MANAGEMENT RISK  
Prospectus [Line Items]  
Risk [Text Block]

ACTIVE MANAGEMENT RISK. The Fund is actively-managed and its performance reflects investment decisions that the Adviser and/or Sub-Adviser makes for the Fund. Such judgments about the Fund’s investments may prove to be incorrect. If the investments selected and the strategies employed by the Fund fail to produce the intended results, the Fund could underperform as compared to other funds with similar investment objectives and/or strategies, or could have negative returns.

Roundhill High Yield Bond WeeklyPay™ ETF | ACTIVE MARKET RISK

ACTIVE MARKET RISK. Although Fund Shares are listed for trading on the Exchange, there can be no assurance that an active trading market for Fund Shares will develop or be maintained. Fund Shares trade on the Exchange at market prices that may be below, at or above the Fund’s net asset value. Securities, including Fund Shares, are subject to market fluctuations and liquidity constraints that may be caused by such factors as economic, political, or regulatory developments, changes in interest rates, and/or perceived trends in securities prices. Fund Shares could decline in value or underperform other investments.

CONCENTRATION RISK. The Fund is susceptible to an increased risk of loss, including losses due to adverse events that affect the Fund’s investments more than the market as a whole, to the extent that the Fund’s investments are concentrated in investments that provide exposure to the High Yield Bond ETF and the industry or group of industries to which it is concentrated.

Roundhill High Yield Bond WeeklyPay™ ETF | COUNTERPARTY RISK  
Prospectus [Line Items]  
Risk [Text Block]

COUNTERPARTY RISK. Fund transactions involving a counterparty are subject to the risk that the counterparty will not fulfill its obligation to the Fund. Counterparty risk may arise because of the counterparty’s financial condition (i.e., financial difficulties, bankruptcy, or insolvency), market activities and developments, or other reasons, whether foreseen or not. A counterparty’s inability to fulfill its obligation may result in significant financial loss to the Fund. The Fund may be unable to recover its investment from the counterparty or may obtain a limited recovery, and/or recovery may be delayed.

Roundhill High Yield Bond WeeklyPay™ ETF | CURRENT MARKET CONDITIONS RISK  
Prospectus [Line Items]  
Risk [Text Block]

CURRENT MARKET CONDITIONS RISK. Current market conditions risk is the risk that a particular investment, or Fund Shares in general, may fall in value due to current market conditions. As a means to fight inflation, which remains at elevated levels, the Federal Reserve and certain foreign central banks have raised interest rates; however, the Federal Reserve has recently lowered interest rates and may continue to do so. U.S. regulators have proposed several changes to market and issuer regulations which would directly impact the Fund, and any regulatory changes could adversely impact the Fund’s ability to achieve its investment strategies or make certain investments. Recent and potential future bank failures could result in disruption to the broader banking industry or markets generally and reduce confidence in financial institutions and the economy as a whole, which may also heighten market volatility and reduce liquidity. Additionally, challenges in commercial real estate markets, including rising interest rates, declining valuations and increasing vacancies, could have a broader impact on financial markets. The ongoing adversarial political climate in the United States, as well as political and diplomatic events both domestic and abroad, have and may continue to have an adverse impact the U.S. regulatory landscape, markets and investor behavior, which could have a negative impact on the Fund’s investments and operations. The change in administration resulting from the 2024 United States national elections could result in significant impacts to international trade relations, tax and immigration policies, and other aspects of the national and international political and financial landscape, which could affect, among other things, inflation and the securities markets generally. Other unexpected political, regulatory and diplomatic events within the U.S. and abroad may affect investor and consumer confidence and may adversely impact financial markets and the broader economy. For example, ongoing armed conflicts between Russia and Ukraine in Europe and among Israel, Iran, Hamas and other militant groups in the Middle East, have caused and could continue to cause significant market disruptions and volatility within the markets in Russia, Europe, the Middle East and the United States. The hostilities and sanctions resulting from those hostilities have and could continue to have a significant impact on certain Fund investments as well as Fund performance and liquidity. The economies of the United States and its trading partners, as well as the financial markets generally, may be adversely impacted by trade disputes, including the imposition of tariffs, and other matters. For example, the United States has imposed trade barriers and restrictions on China. In addition, the Chinese government is engaged in a longstanding dispute with Taiwan, continually threatening an invasion. If the political climate between the United States and China does not improve or continues to deteriorate, if China were to attempt invading Taiwan, or if other geopolitical conflicts develop or worsen, economies, markets and individual securities may be adversely affected, and the value of the Fund’s assets may go down. A public health crisis and the ensuing policies enacted by governments and central banks may cause significant volatility and uncertainty in global financial markets, negatively impacting global growth prospects. As the COVID-19 global pandemic illustrated, such events may affect certain geographic regions, countries, sectors and industries more significantly than others. Advancements in technology may also adversely impact markets and the overall performance of the Fund. For instance, the economy may be significantly impacted by the advanced development and increased regulation of artificial intelligence. Additionally, cyber security breaches of both government and non-government entities could have negative impacts on infrastructure and the ability of such entities, including the Fund, to operate properly. These events, and any other future events, may adversely affect the prices and liquidity of the Fund’s portfolio investments and could result in disruptions in the trading markets.

Roundhill High Yield Bond WeeklyPay™ ETF | CYBERSECURITY RISK  
Prospectus [Line Items]  
Risk [Text Block]

CYBERSECURITY RISK. Failures or breaches of the electronic systems of the Fund, the Fund’s adviser, sub-adviser, distributor and other service providers, market makers, Authorized Participants or the issuers of securities in which the Fund invests have the ability to cause disruptions, negatively impact the Fund’s business operations and/or potentially result in financial losses to the Fund and its shareholders. While the Fund has established business continuity plans and risk management systems seeking to address system breaches or failures, there are inherent limitations in such plans and systems. Furthermore, the Fund cannot control the cybersecurity plans and systems of the Fund’s other service providers, market makers, Authorized Participants or issuers of securities in which the Fund invests.

Roundhill High Yield Bond WeeklyPay™ ETF | DEBT SECURITIES RISK  
Prospectus [Line Items]  
Risk [Text Block]

DEBT SECURITIES RISK. Investments in debt securities subject the holder to the credit risk of the issuer. Credit risk refers to the possibility that the issuer or other obligor of a security will not be able or willing to make payments of interest and principal when due. Generally, the value of debt securities will change inversely with changes in interest rates. To the extent that interest rates rise, certain underlying obligations may be paid off substantially slower than originally anticipated and the value of those securities may fall sharply. During periods of falling interest rates, the income received by the Fund may decline. If the principal on a debt security is prepaid before expected, the prepayments of principal may have to be reinvested in obligations paying interest at lower rates. Debt securities generally do not trade on a securities exchange making them generally less liquid and more difficult to value than common stock.

Roundhill High Yield Bond WeeklyPay™ ETF | DERIVATIVES RISK  
Prospectus [Line Items]  
Risk [Text Block]

DERIVATIVES RISK. The use of derivative instruments involves risks different from, or possibly greater than, the risks associated with investing directly in securities and other traditional investments. These risks include: (i) the risk that the counterparty to a derivative transaction may not fulfill its contractual obligations; (ii) risk of mispricing or improper valuation; and (iii) the risk that changes in the value of the derivative may not correlate perfectly with the underlying asset. Derivative prices are highly volatile and may fluctuate substantially during a short period of time. Such prices are influenced by numerous factors that affect the markets, including, but not limited to: changing supply and demand relationships; government programs and policies; national and international political and economic events, changes in interest rates, inflation and deflation and changes in supply and demand relationships. Trading derivative instruments involves risks different from, or possibly greater than, the risks associated with investing directly in securities. Derivative contracts ordinarily have leverage inherent in their terms. The use of leverage may cause the Fund to liquidate portfolio positions when it would not be advantageous to do so in order to satisfy its obligations or to meet regulatory or contractual requirements for derivatives. The use of derivatives can magnify potential for gain or loss and, therefore, amplify the effects of market volatility on share price.

Roundhill High Yield Bond WeeklyPay™ ETF | DISTRIBUTION TAX RISK  
Prospectus [Line Items]  
Risk [Text Block]

DISTRIBUTION TAX RISK. The Fund currently expects to make distributions on a weekly basis. Such frequent distributions may expose investors to increased tax liabilities. However, these distributions may exceed the Fund’s income and gains for the Fund’s taxable year. Distributions in excess of the Fund’s current and accumulated earnings and profits will be treated as a return of capital. A return of capital distribution generally will not be taxable but will reduce the shareholder’s cost basis and will result in a higher capital gain or lower capital loss when those Fund Shares on which the distribution was received are sold. Once a Fund shareholder’s cost basis is reduced to zero, further distributions will be treated as capital gain if the Fund shareholder holds Fund Shares as capital assets. Additionally, any capital returned through distributions will be distributed after payment of Fund fees and expenses. Because a portion of the Fund’s distributions may consist of return of capital, the Fund may not be an appropriate investment for investors who do not want their principal investment in the Fund to decrease over time or who do not wish to receive return of capital in a given period. In the event that a shareholder purchases Fund Shares shortly before a distribution by the Fund, the entire distribution may be taxable to the shareholder even though a portion of the distribution effectively represents a return of the purchase price.

Roundhill High Yield Bond WeeklyPay™ ETF | ETF RISK  
Prospectus [Line Items]  
Risk [Text Block]

ETF RISK. The Fund may invest in ETFs. The value of an ETF held by the Fund will fluctuate over time based on fluctuations in the values of the assets held by the ETF, which may be affected by changes in general economic conditions, expectations for future growth and profits, interest rates and the supply and demand for those assets. When the Fund invests in an ETF, it will bear a proportionate share of the ETF’s expenses. Brokerage, tax and other expenses may negatively impact the performance of the ETF and, in turn, the value of the Fund Shares. An ETF that tracks an index may not exactly match the performance of the index due to cash drag, differences between the portfolio of the ETF and the components of the index, expenses and other factors.

Roundhill High Yield Bond WeeklyPay™ ETF | INFLATION RISK  
Prospectus [Line Items]  
Risk [Text Block]

INFLATION RISK. Inflation risk is the risk that the value of assets or income from investments will be less in the future as inflation decreases the value of money. As inflation increases, the present value of the Fund’s assets and distributions may decline. This risk is more prevalent with respect to fixed income securities held by the Fund.

Roundhill High Yield Bond WeeklyPay™ ETF | Interest Rate Risk [Member]  
Prospectus [Line Items]  
Risk [Text Block]

INTEREST RATE RISK. Interest rate risk is the risk that the value of the debt securities in the Fund’s portfolio will decline because of rising market interest rates. Interest rate risk is generally lower for shorter term debt securities and higher for longer-term debt securities. Duration is a reasonably accurate measure of a debt security’s price sensitivity to changes in interest rates and a common measure of interest rate risk. Duration measures a debt security’s expected life on a present value basis, taking into account the debt security’s yield, interest payments and final maturity. In general, duration represents the expected percentage change in the value of a security for an immediate 1% change in interest rates. For example, the price of a debt security with a three-year duration would be expected to drop by approximately 3% in response to a 1% increase in interest rates. Therefore, prices of debt securities with shorter durations tend to be less sensitive to interest rate changes than debt securities with longer durations. As the value of a debt security changes over time, so will its duration.

Roundhill High Yield Bond WeeklyPay™ ETF | LEGISLATION AND LITIGATION RISK  
Prospectus [Line Items]  
Risk [Text Block]

LEGISLATION AND LITIGATION RISK. Legislation or litigation that affects the value of assets or securities held by the Fund may reduce the value of the Fund. From time to time, various legislative initiatives are proposed that may have a negative impact on certain assets or securities in which the Fund invests. In addition, litigation regarding any of the assets or securities owned by the Fund may negatively impact the value of the Shares. Such legislation or litigation may cause the Fund to lose value or may result in higher portfolio turnover if the Adviser determines to sell such a holding.

Roundhill High Yield Bond WeeklyPay™ ETF | LEVERAGE RISK  
Prospectus [Line Items]  
Risk [Text Block]

LEVERAGE RISK. The Fund obtains investment exposure in excess of its net assets by utilizing leverage and may lose more money in market conditions that are adverse to its investment objectives than a fund that does not utilize leverage. An investment in the Fund is exposed to the risk that a decline in the weekly performance of shares of the High Yield Bond ETF will be magnified. This means that an investment in the Fund will be reduced by an amount equal to 1.2% for every 1% weekly decline in the market value of the High Yield Bond ETF shares, not including the costs of financing leverage and other operating expenses, which would further reduce its value. The Fund could theoretically lose an amount greater than its net assets in the event the market value of the High Yield Bond ETF shares decline more than 83.33% over a calendar week. Leverage will also have the effect of magnifying any differences in the Fund’s correlation with the High Yield Bond ETF shares.

Roundhill High Yield Bond WeeklyPay™ ETF | MONEY MARKET INSTRUMENTS RISK  
Prospectus [Line Items]  
Risk [Text Block]

MONEY MARKET INSTRUMENTS RISK. The value of money market instruments may be affected by changing interest rates and by changes in the credit ratings of the investments. If a significant amount of the Fund’s assets are invested in money market instruments, it will be more difficult for the Fund to achieve its investment objectives. An investment in a money market fund is not insured or guaranteed by the FDIC or any other government agency. It is possible to lose money by investing in a money market fund.

Roundhill High Yield Bond WeeklyPay™ ETF | OPERATIONAL RISK  
Prospectus [Line Items]  
Risk [Text Block]

OPERATIONAL RISK. The Fund is subject to risks arising from various operational factors, including, but not limited to, human error, processing and communication errors, errors of the Fund’s service providers, counterparties or other third-parties, failed or inadequate processes and technology or systems failures. The Fund relies on third-parties for a range of services, including custody. Any delay or failure relating to engaging or maintaining such service providers may affect the Fund’s ability to meet its investment objectives. Although the Fund and the Adviser seek to reduce these operational risks through controls and procedures, there is no way to completely protect against such risks.

Roundhill High Yield Bond WeeklyPay™ ETF | SPECIAL TAX RISK  
Prospectus [Line Items]  
Risk [Text Block]

SPECIAL TAX RISK. The Fund intends to qualify annually and to elect to be treated as a regulated investment company under the Internal Revenue Code of 1986, as amended (the “Code”). To qualify for the favorable U.S. federal income tax treatment generally accorded to regulated investment companies, the Fund must, among other things, (i) derive in each taxable year at least 90% of its gross income from dividends, interest, payments with respect to securities loans and gains from the sale or other disposition of stock, securities or foreign currencies or other income derived with respect to its business of investing in such stock, securities or currencies, or net income derived from interests in certain publicly traded partnerships; (ii) diversify its holdings so that, at the end of each quarter of the taxable year, (a) at least 50% of the market value of the Fund’s assets is represented by cash and cash items (including receivables), U.S. government securities, the securities of other regulated investment companies and other securities, with such other securities of any one issuer generally limited for the purposes of this calculation to an amount not greater than 5% of the value of the Fund’s total assets and not greater than 10% of the outstanding voting securities of such issuer, and (b) not more than 25% of the value of its total assets is invested in the securities (other than U.S. government securities or the securities of other regulated investment companies) of any one issuer, or two or more issuers which the Fund controls which are engaged in the same, similar or related trades or businesses, or the securities of one or more of certain publicly traded partnerships; and (iii) distribute at least 90% of its investment company taxable income (which includes, among other items, dividends, interest and net short-term capital gains in excess of net long-term capital losses) and at least 90% of its net tax-exempt interest income each taxable year. There are certain exceptions for failure to qualify if the failure is for reasonable cause or is de minimis, and certain corrective action is taken and certain tax payments are made by the Fund.

 

The authority with regard to swaps entered into by regulated investment companies is unclear both as to the qualification under the income test and the identification of the issuer under the diversification test. The Fund intends to take the position that because the swaps held by the Fund reference securities that the income on the swaps are “other income” from the Fund’s business of investing in stocks and securities. In addition, the Fund intends to manage its investments in the swaps so that neither the exposure to issuer of the referenced security nor the exposure to any one counterparty of the swaps will exceed 25% of the gross value of the Fund’s portfolio at the end of any quarter.

 

If the Fund were to fail to meet the qualifying income test or asset diversification test and fail to qualify as a RIC, it would be taxed in the same manner as an ordinary corporation, and distributions to its shareholders would not be deductible by the Fund in computing its taxable income, which would adversely affect the Fund’s performance.

Roundhill High Yield Bond WeeklyPay™ ETF | STRUCTURAL ETF RISKS  
Prospectus [Line Items]  
Risk [Text Block]

STRUCTURAL ETF RISKS. The Fund is an ETF. Accordingly, it is subject to certain risks associated with its unique structure.

 

Market Participants Risk. Only an Authorized Participant may engage in creation or redemption transactions directly with the Fund, and none of those Authorized Participants is obligated to engage in creation and/or redemption transactions. The Fund has a limited number of institutions that may act as Authorized Participants on an agency basis (i.e., on behalf of other market participants). To the extent that Authorized Participants exit the business or are unable to proceed with creation or redemption orders with respect to the Fund and no other Authorized Participant is able to step forward to create or redeem, Fund Shares may be more likely to trade at a premium or discount to NAV and possibly face trading halts or delisting. The Fund may also rely on a small number of third-party market makers to provide a market for the purchase and sale of Fund Shares but such market makers are under no obligation to do so. Decisions by Authorized Participants or market makers to reduce their role or step away from these activities in times of market stress could inhibit the effectiveness of the arbitrage process in maintaining the relationship between the underlying values of the Fund’s portfolio securities and the Fund’s market price. Any trading halt or other problem relating to the trading activity of these market makers or any issues disrupting the Authorized Participants’ ability to proceed with creation and/or redemption orders could result in a dramatic change in the spread between the Fund’s net asset value and the price at which Fund Shares are trading on the Exchange, which could result in a decrease in value of Fund Shares. This reduced effectiveness could result in Fund Shares trading at a premium or discount to net asset value and also in greater than normal intraday bid-ask spreads Fund Shares.

 

Cash Transactions Risk. The Fund currently expects to effect a significant portion of its creations and redemptions for cash, rather than in-kind securities. Paying redemption proceeds in cash rather than through in-kind delivery of portfolio securities may require the Fund to dispose of or sell portfolio securities or other assets at an inopportune time to obtain the cash needed to meet redemption orders. This may cause the Fund to sell a security and recognize a capital gain or loss that might not have been incurred if it had made a redemption in-kind. As a result, the Fund may pay out higher or lower annual capital gains distributions than ETFs that redeem in-kind. The use of cash creations and redemptions may also cause the Fund’s Shares to trade in the market at greater bid-ask spreads or greater premiums or discounts to the Fund’s NAV. Furthermore, the Fund may not be able to execute cash transactions for creation and redemption purposes at the same price used to determine the Fund’s NAV. To the extent that the maximum additional charge for creation or redemption transactions is insufficient to cover the execution shortfall, the Fund’s performance could be negatively impacted.

 

Costs of Buying and Selling Fund Shares. Due to the costs of buying or selling Fund Shares, including brokerage commissions imposed by brokers and bid/ask spreads, frequent trading of Fund Shares may significantly reduce investment results and an investment in Fund Shares may not be advisable for investors who anticipate regularly making small investments.

 

Premium/Discount Risk. As with all ETFs, Fund Shares may be bought and sold in the secondary market at market prices. The trading prices of Fund Shares in the secondary market may differ from the Fund’s daily net asset value per share and there may be times when the market price of the shares is more than the net asset value per share (premium) or less than the net asset value per share (discount). If a shareholder purchases Fund Shares at a time when the market price is at a premium to the net asset value or sells Fund Shares at a time when the market price is at a discount to the net asset value, the shareholder may pay more for, or receive less than, the underlying value of the Fund Shares, respectively. This risk is heightened in times of market volatility or periods of steep market declines.

 

Trading Risks. Although Fund Shares are listed for trading on the Exchange and may be traded on U.S. exchanges other than the Exchange, there can be no assurance that Fund Shares will trade with any volume, or at all, on any stock exchange. In stressed market conditions, the liquidity of Fund Shares may begin to mirror the liquidity of the Fund’s underlying portfolio holdings, which can be significantly less liquid than Fund Shares. Trading in Fund Shares on the Exchange may be halted due to market conditions or for reasons that, in the view of the Exchange, make trading in Fund Shares inadvisable. In addition, trading in Fund Shares on the Exchange is subject to trading halts caused by extraordinary market volatility pursuant to the Exchange’s “circuit breaker” rules. There can be no assurance that the requirements of the Exchange necessary to maintain the listing of the Fund will continue to be met or will remain unchanged.

Risk [Text Block]

U.S. GOVERNMENT SECURITIES RISK. U.S. government securities are subject to interest rate risk but generally do not involve the credit risks associated with investments in other types of debt securities. As a result, the yields available from U.S. government securities are generally lower than the yields available from other debt securities. U.S. government securities are guaranteed only as to the timely payment of interest and the payment of principal when held to maturity.

Roundhill High Yield Bond WeeklyPay™ ETF | VALUATION RISK  
Prospectus [Line Items]  
Risk [Text Block]

VALUATION RISK. The Fund may hold securities or other assets that may be valued on the basis of factors other than market quotations. This may occur because the asset or security does not trade on a centralized exchange, or in times of market turmoil or reduced liquidity. There are multiple methods that can be used to value a portfolio holding when market quotations are not readily available. The value established for any portfolio holding at a point in time might differ from what would be produced using a different methodology or if it had been priced using market quotations. Portfolio holdings that are valued using techniques other than market quotations, including “fair valued” assets or securities, may be subject to greater fluctuation in their valuations from one day to the next than if market quotations were used. In addition, there is no assurance that the Fund could sell or close out a portfolio position for the value established for it at any time, and it is possible that the Fund would incur a loss because a portfolio position is sold or closed out at a discount to the valuation established by the Fund at that time. The Fund’s ability to value investments may be impacted by technological issues or errors by pricing services or other third-party service providers.

Roundhill High Yield Bond WeeklyPay™ ETF | EQUITY SECURITIES RISK  
Prospectus [Line Items]  
Risk [Text Block]

EQUITY SECURITIES RISK. Equity securities are subject to changes in value, and their values may be more volatile than those of other asset classes. Equity securities prices fluctuate for several reasons, including changes in investors’ perceptions of the financial condition of an issuer or the general condition of the relevant equity market, such as market volatility, or when political or economic events affecting an issuer occur. Common stock prices may be particularly sensitive to rising interest rates, as the cost of capital rises and borrowing costs increase. Common stocks generally subject their holders to more risks than preferred stocks and debt securities because common stockholders’ claims are subordinated to those of holders of preferred stocks and debt securities upon the bankruptcy of the issuer.

Roundhill High Yield Bond WeeklyPay™ ETF | SWAP AGREEMENTS RISK  
Prospectus [Line Items]  
Risk [Text Block]

SWAP AGREEMENTS RISK. The Fund will utilize swap agreements to derive its exposure to shares of the High Yield Bond ETF. Swap agreements may involve greater risks than direct investment in securities as they may be leveraged and are subject to credit risk, counterparty risk and valuation risk. A swap agreement could result in losses if the underlying reference or asset does not perform as anticipated. In addition, many swaps trade over-the-counter and may be considered illiquid. It may not be possible for the Fund to liquidate a swap position at an advantageous time or price, which may result in significant losses.

Roundhill High Yield Bond WeeklyPay™ ETF | NEW FUND RISK  
Prospectus [Line Items]

NEW FUND RISK. The Fund is a recently organized investment company with a limited operating history. As a result, prospective investors have a limited track record or history on which to base their investment decision.

Roundhill High Yield Bond WeeklyPay™ ETF | REGULATED INVESTMENT COMPANY TAX RISKS  
Prospectus [Line Items]  
Risk [Text Block]

REGULATED INVESTMENT COMPANY TAX RISKS. The Fund intends to qualify annually and to elect to be treated as a regulated investment company under the Internal Revenue Code of 1986, as amended (the “Code”). To qualify for the favorable U.S. federal income tax treatment generally accorded to regulated investment companies, the Fund must, among other things, (i) derive in each taxable year at least 90% of its gross income from dividends, interest, payments with respect to securities loans and gains from the sale or other disposition of stock, securities or foreign currencies or other income derived with respect to its business of investing in such stock, securities or currencies, or net income derived from interests in certain publicly traded partnerships; (ii) diversify its holdings so that, at the end of each quarter of the taxable year, (a) at least 50% of the market value of the Fund’s assets is represented by cash and cash items (including receivables), U.S. government securities, the securities of other regulated investment companies and other securities, with such other securities of any one issuer generally limited for the purposes of this calculation to an amount not greater than 5% of the value of the Fund’s total assets and not greater than 10% of the outstanding voting securities of such issuer, and (b) not more than 25% of the value of its total assets is invested in the securities (other than U.S. government securities or the securities of other regulated investment companies) of any one issuer, or two or more issuers which the Fund controls which are engaged in the same, similar or related trades or businesses, or the securities of one or more of certain publicly traded partnerships; and (iii) distribute at least 90% of its investment company taxable income (which includes, among other items, dividends, interest and net short-term capital gains in excess of net long-term capital losses) and at least 90% of its net tax-exempt interest income each taxable year. There are certain exceptions for failure to qualify if the failure is for reasonable cause or is de minimis, and certain corrective action is taken and certain tax payments are made by the Fund.

 

If the Fund were to fail to meet the qualifying income test or asset diversification test and fail to qualify as a RIC, it would be taxed in the same manner as an ordinary corporation, and distributions to its shareholders would not be deductible by the Fund in computing its taxable income, which would adversely affect the Fund’s performance.

Roundhill High Yield Bond WeeklyPay™ ETF | LARGE SHAREHOLDER RISK  
Prospectus [Line Items]  
Risk [Text Block]

LARGE SHAREHOLDER RISK. Certain shareholders, including affiliated funds advised by the Adviser, may from time to time own a significant portion of the Fund’s shares. In addition, a third-party investor, the Adviser or an affiliate of the Adviser (“Affiliate”), an authorized participant, a market maker, or another entity may invest in the Fund and hold its investment for a limited period solely to facilitate the commencement of the Fund or to help the Fund achieve a specified size or scale. There can be no assurance that any large shareholder will not redeem its investment, that the size of the Fund will be maintained at such levels, or that the Fund will continue to meet applicable listing requirements. Redemptions by large shareholders could have a significant negative impact on the Fund. In addition, transactions by large shareholders may account for a large percentage of the trading volume on the Fund’s listing exchange and may, therefore, have a material upward or downward effect on the market price of the shares.

 

To the extent that a significant percentage of the Fund’s shares are owned or controlled by a small number of account shareholders (or a single account shareholder), including funds or accounts over which the Adviser or an Affiliate has investment discretion, the Fund is subject to the risk that those shareholders may purchase or redeem Fund shares in significant amounts rapidly or unexpectedly, including as a result of an asset allocation decision made by the Adviser or an Affiliate. This may adversely affect the Fund’s performance if the Adviser is forced to sell portfolio securities or invest cash when it would not otherwise choose to do so. Redemptions of a large number of shares may affect the liquidity of the Fund’s portfolio, increase the Fund’s transaction costs, and accelerate the realization of taxable income and/or gains. In addition, a large redemption could result in the Fund’s current expenses being allocated over a smaller asset base, leading to an increase in the Fund’s gross expense ratio. Large purchases of the Fund’s shares may also adversely affect the Fund’s performance to the extent that the Fund is delayed in investing new cash or otherwise maintains a larger cash position than it ordinarily would, particularly if the Fund accepts cash for an order for the purchase of creation units of the Fund’s shares.

Roundhill High Yield Bond WeeklyPay™ ETF | HIGH YIELD BOND ETF INVESTING RISKS  
Prospectus [Line Items]  
Risk [Text Block]

HIGH YIELD BOND ETF INVESTING RISKS. The Fund will have significant exposure to the High Yield Bond ETF through its investments in shares of the High Yield Bond ETF and swap agreements that utilize the High Yield Bond ETF as the reference asset. Accordingly, the Fund will subject to the risks of the High Yield Bond ETF, set forth below. In addition to these risks, the High Yield Bond ETF is also subject to the following risks to which the Fund is also subject, which are described within the section entitled “Principal Risks”: Market Risk, Asset Class Risk, Concentration Risk, Credit Risk, Current Market Conditions Risk, Cybersecurity Risk, Debt Securities Risk, ETF Risk, Interest Rate Risk, Operational Risk, Structural ETF Risk, U.S. Government Securities Risk and Valuation Risk.

 

CALL RISK. During periods of falling interest rates, an issuer of a callable bond held by the High Yield Bond ETF may “call” or repay the security before its stated maturity, and the High Yield Bond ETF may have to reinvest the proceeds in securities with lower yields, which would result in a decline in the High Yield Bond ETF’s income, or in securities with greater risks or with other less favorable features.

 

EXTENSION RISK. During periods of rising interest rates, certain debt obligations may be paid off substantially more slowly than originally anticipated and the value of those securities may fall sharply, resulting in a decline in the High Yield Bond ETF’s income and potentially in the value of the High Yield Bond ETF’s investments.

 

INCOME RISK. The High Yield Bond ETF’s income may decline due to falling interest rates or other factors. This can occur because the High Yield Bond ETF may be required to invest in lower-yielding bonds when a bond in the High Yield Bond ETF’s portfolio matures, is near maturity, is called or is prepaid, when bonds in the High Yield Bond ETF Index are substituted, or when the High Yield Bond ETF otherwise needs to purchase additional bonds. The High Yield Bond ETF Index Provider’s substitution of bonds in the High Yield Bond ETF Index may occur, for example, when the time to maturity for the bond no longer matches the High Yield Bond ETF Index’s stated maturity guidelines.

 

INDEX-RELATED RISK. The High Yield Bond ETF Index Provider may rely on various sources of information to assess the criteria of components of the High Yield Bond ETF Index, including information that may be based on assumptions and estimates. Neither the High Yield Bond ETF nor its investment adviser offer assurances that the High Yield Bond ETF Index Provider’s methodology or sources of information will provide an accurate assessment of included components or will result in the High Yield Bond ETF meeting its investment objective. Errors in index data, index computations or the construction of the High Yield Bond ETF Index in accordance with its methodology may occur, and the High Yield Bond ETF Index Provider may not identify or correct them promptly or at all, which may have an adverse impact on the High Yield Bond ETF and its shareholders. Unusual market conditions or other unforeseen circumstances (such as natural disasters, political unrest or war) may impact the High Yield Bond ETF Index Provider or a third-party data provider and could cause the High Yield Bond ETF Index Provider to postpone a scheduled rebalance. This could cause the High Yield Bond ETF Index to vary from its normal or expected composition.

 

HIGH YIELD SECURITIES RISK. Debt securities that are rated below investment grade (commonly referred to as “junk bonds”) and debt securities that are unrated are generally considered to be speculative. Compared to higher-quality debt securities, high yield securities are subject to a greater risk of default, illiquidity, price volatility and valuation uncertainty. Such investments may be subject to additional risks including subordination to other creditors, no collateral or limited rights in collateral, lack of a regular trading market, prepayment risk, and lack of publicly available information.

 

INDIRECT INVESTMENT RISK. The High Yield Bond ETF is not affiliated with the Trust, the Fund, the Adviser, the Sub-Adviser or any affiliates thereof and is not involved with this offering in any way, and has no obligation to consider the Fund in taking any actions that might affect the value of the Fund. The Trust, the Fund, the Adviser, the Sub-Adviser or any affiliate are not responsible for the performance of the High Yield Bond ETF and make no representation as to the performance of the High Yield Bond ETF. Investing in the Fund is not equivalent to investing in the High Yield Bond ETF Fund shareholders will not have voting rights or rights to receive dividends or other distributions or any other rights with respect to the High Yield Bond ETF.

 

UNITED STATES RISK. Certain changes in the U.S. economy, such as when the U.S. economy weakens or when its financial markets decline, may have an adverse effect on the securities to which the Fund has exposure.

NON-DIVERSIFICATION RISK. As a “non-diversified” fund, the Fund may hold a smaller number of portfolio securities than many other funds. To the extent the Fund invests in a relatively small number of issuers, a decline in the market value of a particular security held by the Fund may affect its value more than if it invested in a larger number of issuers. The value of the Fund Shares may be more volatile than the values of shares of more diversified funds.

Roundhill Bitcoin WeeklyPay™ ETF | MARKET RISK  
Prospectus [Line Items]  
Risk [Text Block]

MARKET RISK. Market risk is the risk that a particular investment, or Fund Shares in general, may fall in value. Securities are subject to market fluctuations caused by real or perceived adverse economic, political, and regulatory factors or market developments, changes in interest rates, disruptions to trade, impositions of tariffs and perceived trends in securities prices. Fund Shares could decline in value or underperform other investments. In addition, local, regional or global events such as war, acts of terrorism, market manipulation, government defaults, government shutdowns, regulatory actions, political changes, diplomatic developments, the imposition of sanctions and other similar measures, spread of infectious diseases or other public health issues, recessions, natural disasters, or other events could have a significant negative impact on the Fund and its investments. Any of such circumstances could have a materially negative impact on the value of Fund Shares, the liquidity of an investment, and may result in increased market volatility. During any such events, Fund Shares may trade at increased premiums or discounts to their net asset value, the bid/ask spread on Fund Shares may widen and the returns on investment may fluctuate.

Roundhill Bitcoin WeeklyPay™ ETF | LIQUIDITY RISK  
Prospectus [Line Items]  
Risk [Text Block]

LIQUIDITY RISK. The market for swap agreements that reference the Bitcoin ETF shares may be subject to periods of illiquidity. During such times it may be difficult or impossible to buy or sell a position at the desired price. Market disruptions or volatility can also make it difficult to find a counterparty willing to transact at a reasonable price and sufficient size. Illiquid markets may cause losses, which could be significant. The large size of the positions which the Fund may acquire increases the risk of illiquidity, may make its positions more difficult to liquidate, and may increase the losses incurred while trying to do so. Such large positions also may impact the price of swap agreements on the Bitcoin ETF shares.

Roundhill Bitcoin WeeklyPay™ ETF | ACTIVE MANAGEMENT RISK  
Prospectus [Line Items]  
Risk [Text Block]

ACTIVE MANAGEMENT RISK. The Fund is actively-managed and its performance reflects investment decisions that the Adviser and/or Sub-Adviser makes for the Fund. Such judgments about the Fund’s investments may prove to be incorrect. If the investments selected and the strategies employed by the Fund fail to produce the intended results, the Fund could underperform as compared to other funds with similar investment objectives and/or strategies, or could have negative returns.

Roundhill Bitcoin WeeklyPay™ ETF | ACTIVE MARKET RISK

ACTIVE MARKET RISK. Although Fund Shares are listed for trading on the Exchange, there can be no assurance that an active trading market for Fund Shares will develop or be maintained. Fund Shares trade on the Exchange at market prices that may be below, at or above the Fund’s net asset value. Securities, including Fund Shares, are subject to market fluctuations and liquidity constraints that may be caused by such factors as economic, political, or regulatory developments, changes in interest rates, and/or perceived trends in securities prices. Fund Shares could decline in value or underperform other investments.

CONCENTRATION RISK. The Fund is susceptible to an increased risk of loss, including losses due to adverse events that affect the Fund’s investments more than the market as a whole, to the extent that the Fund’s investments are concentrated in investments or instruments that provide exposure to bitcoin.

Roundhill Bitcoin WeeklyPay™ ETF | COUNTERPARTY RISK  
Prospectus [Line Items]  
Risk [Text Block]

COUNTERPARTY RISK. Fund transactions involving a counterparty are subject to the risk that the counterparty will not fulfill its obligation to the Fund. Counterparty risk may arise because of the counterparty’s financial condition (i.e., financial difficulties, bankruptcy, or insolvency), market activities and developments, or other reasons, whether foreseen or not. A counterparty’s inability to fulfill its obligation may result in significant financial loss to the Fund. The Fund may be unable to recover its investment from the counterparty or may obtain a limited recovery, and/or recovery may be delayed.

Roundhill Bitcoin WeeklyPay™ ETF | CURRENT MARKET CONDITIONS RISK  
Prospectus [Line Items]  
Risk [Text Block]

CURRENT MARKET CONDITIONS RISK. Current market conditions risk is the risk that a particular investment, or Fund Shares in general, may fall in value due to current market conditions. As a means to fight inflation, which remains at elevated levels, the Federal Reserve and certain foreign central banks have raised interest rates; however, the Federal Reserve has recently lowered interest rates and may continue to do so. U.S. regulators have proposed several changes to market and issuer regulations which would directly impact the Fund, and any regulatory changes could adversely impact the Fund’s ability to achieve its investment strategies or make certain investments. Recent and potential future bank failures could result in disruption to the broader banking industry or markets generally and reduce confidence in financial institutions and the economy as a whole, which may also heighten market volatility and reduce liquidity. Additionally, challenges in commercial real estate markets, including rising interest rates, declining valuations and increasing vacancies, could have a broader impact on financial markets. The ongoing adversarial political climate in the United States, as well as political and diplomatic events both domestic and abroad, have and may continue to have an adverse impact the U.S. regulatory landscape, markets and investor behavior, which could have a negative impact on the Fund’s investments and operations. The change in administration resulting from the 2024 United States national elections could result in significant impacts to international trade relations, tax and immigration policies, and other aspects of the national and international political and financial landscape, which could affect, among other things, inflation and the securities markets generally. Other unexpected political, regulatory and diplomatic events within the U.S. and abroad may affect investor and consumer confidence and may adversely impact financial markets and the broader economy. For example, ongoing armed conflicts between Russia and Ukraine in Europe and among Israel, Iran, Hamas and other militant groups in the Middle East, have caused and could continue to cause significant market disruptions and volatility within the markets in Russia, Europe, the Middle East and the United States. The hostilities and sanctions resulting from those hostilities have and could continue to have a significant impact on certain Fund investments as well as Fund performance and liquidity. The economies of the United States and its trading partners, as well as the financial markets generally, may be adversely impacted by trade disputes, including the imposition of tariffs, and other matters. For example, the United States has imposed trade barriers and restrictions on China. In addition, the Chinese government is engaged in a longstanding dispute with Taiwan, continually threatening an invasion. If the political climate between the United States and China does not improve or continues to deteriorate, if China were to attempt invading Taiwan, or if other geopolitical conflicts develop or worsen, economies, markets and individual securities may be adversely affected, and the value of the Fund’s assets may go down. A public health crisis and the ensuing policies enacted by governments and central banks may cause significant volatility and uncertainty in global financial markets, negatively impacting global growth prospects. As the COVID-19 global pandemic illustrated, such events may affect certain geographic regions, countries, sectors and industries more significantly than others. Advancements in technology may also adversely impact markets and the overall performance of the Fund. For instance, the economy may be significantly impacted by the advanced development and increased regulation of artificial intelligence. Additionally, cyber security breaches of both government and non-government entities could have negative impacts on infrastructure and the ability of such entities, including the Fund, to operate properly. These events, and any other future events, may adversely affect the prices and liquidity of the Fund’s portfolio investments and could result in disruptions in the trading markets.

Roundhill Bitcoin WeeklyPay™ ETF | CYBERSECURITY RISK  
Prospectus [Line Items]  
Risk [Text Block]

CYBERSECURITY RISK. Failures or breaches of the electronic systems of the Fund, the Fund’s adviser, sub-adviser, distributor and other service providers, market makers, Authorized Participants or the issuers of securities in which the Fund invests have the ability to cause disruptions, negatively impact the Fund’s business operations and/or potentially result in financial losses to the Fund and its shareholders. While the Fund has established business continuity plans and risk management systems seeking to address system breaches or failures, there are inherent limitations in such plans and systems. Furthermore, the Fund cannot control the cybersecurity plans and systems of the Fund’s other service providers, market makers, Authorized Participants or issuers of securities in which the Fund invests.

Roundhill Bitcoin WeeklyPay™ ETF | DEBT SECURITIES RISK  
Prospectus [Line Items]  
Risk [Text Block]

DEBT SECURITIES RISK. Investments in debt securities subject the holder to the credit risk of the issuer. Credit risk refers to the possibility that the issuer or other obligor of a security will not be able or willing to make payments of interest and principal when due. Generally, the value of debt securities will change inversely with changes in interest rates. To the extent that interest rates rise, certain underlying obligations may be paid off substantially slower than originally anticipated and the value of those securities may fall sharply. During periods of falling interest rates, the income received by the Fund may decline. If the principal on a debt security is prepaid before expected, the prepayments of principal may have to be reinvested in obligations paying interest at lower rates. Debt securities generally do not trade on a securities exchange making them generally less liquid and more difficult to value than common stock.

Roundhill Bitcoin WeeklyPay™ ETF | DERIVATIVES RISK  
Prospectus [Line Items]  
Risk [Text Block]

DERIVATIVES RISK. The use of derivative instruments involves risks different from, or possibly greater than, the risks associated with investing directly in securities and other traditional investments. These risks include: (i) the risk that the counterparty to a derivative transaction may not fulfill its contractual obligations; (ii) risk of mispricing or improper valuation; and (iii) the risk that changes in the value of the derivative may not correlate perfectly with the underlying asset. Derivative prices are highly volatile and may fluctuate substantially during a short period of time. Such prices are influenced by numerous factors that affect the markets, including, but not limited to: changing supply and demand relationships; government programs and policies; national and international political and economic events, changes in interest rates, inflation and deflation and changes in supply and demand relationships. Trading derivative instruments involves risks different from, or possibly greater than, the risks associated with investing directly in securities. Derivative contracts ordinarily have leverage inherent in their terms. The use of leverage may cause the Fund to liquidate portfolio positions when it would not be advantageous to do so in order to satisfy its obligations or to meet regulatory or contractual requirements for derivatives. The use of derivatives can magnify potential for gain or loss and, therefore, amplify the effects of market volatility on share price.

Roundhill Bitcoin WeeklyPay™ ETF | DISTRIBUTION TAX RISK  
Prospectus [Line Items]  
Risk [Text Block]

DISTRIBUTION TAX RISK. The Fund currently expects to make distributions on a weekly basis. Such frequent distributions may expose investors to increased tax liabilities. However, these distributions may exceed the Fund’s income and gains for the Fund’s taxable year. Distributions in excess of the Fund’s current and accumulated earnings and profits will be treated as a return of capital. A return of capital distribution generally will not be taxable but will reduce the shareholder’s cost basis and will result in a higher capital gain or lower capital loss when those Fund Shares on which the distribution was received are sold. Once a Fund shareholder’s cost basis is reduced to zero, further distributions will be treated as capital gain if the Fund shareholder holds Fund Shares as capital assets. Additionally, any capital returned through distributions will be distributed after payment of Fund fees and expenses. Because a portion of the Fund’s distributions may consist of return of capital, the Fund may not be an appropriate investment for investors who do not want their principal investment in the Fund to decrease over time or who do not wish to receive return of capital in a given period. In the event that a shareholder purchases Fund Shares shortly before a distribution by the Fund, the entire distribution may be taxable to the shareholder even though a portion of the distribution effectively represents a return of the purchase price.

Roundhill Bitcoin WeeklyPay™ ETF | ETF RISK  
Prospectus [Line Items]  
Risk [Text Block]

ETF RISK. The Fund may invest in ETFs. The value of an ETF held by the Fund will fluctuate over time based on fluctuations in the values of the assets held by the ETF, which may be affected by changes in general economic conditions, expectations for future growth and profits, interest rates and the supply and demand for those assets. When the Fund invests in an ETF, it will bear a proportionate share of the ETF’s expenses. Brokerage, tax and other expenses may negatively impact the performance of the ETF and, in turn, the value of the Fund Shares. An ETF that tracks an index may not exactly match the performance of the index due to cash drag, differences between the portfolio of the ETF and the components of the index, expenses and other factors.

Roundhill Bitcoin WeeklyPay™ ETF | INFLATION RISK  
Prospectus [Line Items]  
Risk [Text Block]

INFLATION RISK. Inflation risk is the risk that the value of assets or income from investments will be less in the future as inflation decreases the value of money. As inflation increases, the present value of the Fund’s assets and distributions may decline. This risk is more prevalent with respect to fixed income securities held by the Fund.

Roundhill Bitcoin WeeklyPay™ ETF | Interest Rate Risk [Member]  
Prospectus [Line Items]  
Risk [Text Block]

INTEREST RATE RISK. Interest rate risk is the risk that the value of the debt securities in the Fund’s portfolio will decline because of rising market interest rates. Interest rate risk is generally lower for shorter term debt securities and higher for longer-term debt securities. Duration is a reasonably accurate measure of a debt security’s price sensitivity to changes in interest rates and a common measure of interest rate risk. Duration measures a debt security’s expected life on a present value basis, taking into account the debt security’s yield, interest payments and final maturity. In general, duration represents the expected percentage change in the value of a security for an immediate 1% change in interest rates. For example, the price of a debt security with a three-year duration would be expected to drop by approximately 3% in response to a 1% increase in interest rates. Therefore, prices of debt securities with shorter durations tend to be less sensitive to interest rate changes than debt securities with longer durations. As the value of a debt security changes over time, so will its duration.

Roundhill Bitcoin WeeklyPay™ ETF | LEGISLATION AND LITIGATION RISK  
Prospectus [Line Items]  
Risk [Text Block]

LEGISLATION AND LITIGATION RISK. Legislation or litigation that affects the value of assets or securities held by the Fund may reduce the value of the Fund. From time to time, various legislative initiatives are proposed that may have a negative impact on certain assets or securities in which the Fund invests. In addition, litigation regarding any of the assets or securities owned by the Fund may negatively impact the value of the Shares. Such legislation or litigation may cause the Fund to lose value or may result in higher portfolio turnover if the Adviser determines to sell such a holding.

Roundhill Bitcoin WeeklyPay™ ETF | LEVERAGE RISK  
Prospectus [Line Items]  
Risk [Text Block]

LEVERAGE RISK. The Fund obtains investment exposure in excess of its net assets by utilizing leverage and may lose more money in market conditions that are adverse to its investment objectives than a fund that does not utilize leverage. An investment in the Fund is exposed to the risk that a decline in the weekly performance of shares of the Bitcoin ETF will be magnified. This means that an investment in the Fund will be reduced by an amount equal to 1.2% for every 1% weekly decline in the market value of the Bitcoin ETF shares, not including the costs of financing leverage and other operating expenses, which would further reduce its value. The Fund could theoretically lose an amount greater than its net assets in the event the market value of the Bitcoin ETF shares decline more than 83.33% over a calendar week. Leverage will also have the effect of magnifying any differences in the Fund’s correlation with the Bitcoin ETF shares.

Roundhill Bitcoin WeeklyPay™ ETF | MONEY MARKET INSTRUMENTS RISK  
Prospectus [Line Items]  
Risk [Text Block]

MONEY MARKET INSTRUMENTS RISK. The value of money market instruments may be affected by changing interest rates and by changes in the credit ratings of the investments. If a significant amount of the Fund’s assets are invested in money market instruments, it will be more difficult for the Fund to achieve its investment objectives. An investment in a money market fund is not insured or guaranteed by the FDIC or any other government agency. It is possible to lose money by investing in a money market fund.

Roundhill Bitcoin WeeklyPay™ ETF | OPERATIONAL RISK  
Prospectus [Line Items]  
Risk [Text Block]

OPERATIONAL RISK. The Fund is subject to risks arising from various operational factors, including, but not limited to, human error, processing and communication errors, errors of the Fund’s service providers, counterparties or other third-parties, failed or inadequate processes and technology or systems failures. The Fund relies on third-parties for a range of services, including custody. Any delay or failure relating to engaging or maintaining such service providers may affect the Fund’s ability to meet its investment objectives. Although the Fund and the Adviser seek to reduce these operational risks through controls and procedures, there is no way to completely protect against such risks.

Roundhill Bitcoin WeeklyPay™ ETF | SPECIAL TAX RISK  
Prospectus [Line Items]  
Risk [Text Block]

SPECIAL TAX RISK. The Fund intends to qualify as a “regulated investment company” (“RIC”), however, the federal income tax treatment of certain aspects of the proposed operations of the Fund are not entirely clear. This includes the tax aspects of the Fund’s options strategy, the possible application of the “straddle” rules, and various loss limitation provisions of the Internal Revenue Code of 1986, as amended (the “Code”). If, in any year, the Fund fails to qualify as a RIC under the applicable tax laws, the Fund would be taxed as an ordinary corporation.

 

The Fund intends to treat the income it derives from gains on swaps referencing the Bitcoin ETF as “qualifying income” for purposes of the RIC qualification rules under Subchapter M of the Code. It has adopted this position in reliance on an opinion obtained from counsel that income from such investments should constitute “qualifying income,” as shares of the Bitcoin ETF constitute “securities” under Section 2(a)(36) of the 1940 Act. However, this opinion is not binding upon the Internal Revenue Service (“IRS”). If the IRS were to successfully assert that the Fund’s income from such investments was not “qualifying income,” the Fund may fail to qualify as a RIC under Subchapter M if over 10% of its gross income was derived from these investments. If the Fund failed to qualify as a RIC, it would be subject to federal and state income tax on all of its taxable income at regular corporate tax rates with no deduction for any distributions paid to shareholders, which would significantly adversely affect the returns to, and could cause substantial losses for, Fund shareholders.

 

To maintain its status as a RIC, the Fund must distribute 90% of its investment company taxable income annually. In addition, to avoid a non-deductible excise tax, the Fund must distribute 98% of its ordinary income and 98.2% of its capital gain net income. Separately, depending upon the circumstances, sales to fund redemptions could cause the Fund to recognize income that the Fund is required to distribute to maintain the Fund’s RIC status and avoid the excise tax. Funding such distributions could require additional sales, which could require more distributions and affect the projected performance of the Fund. Alternatively, if the Fund only makes distributions to maintain its RIC status and becomes subject to the excise tax, that could also affect the projected performance of the Fund. In either case, the assets sold to fund redemptions, distributions or pay the excise tax will not be available to assist the Fund in meeting its investment objectives.

 

In the event that a shareholder purchases shares of the Fund shortly before a distribution by the Fund, the entire distribution may be taxable to the shareholder even though a portion of the distribution effectively represents a return of the purchase price.

Roundhill Bitcoin WeeklyPay™ ETF | STRUCTURAL ETF RISKS  
Prospectus [Line Items]  
Risk [Text Block]

STRUCTURAL ETF RISKS. The Fund is an ETF. Accordingly, it is subject to certain risks associated with its unique structure.

 

Market Participants Risk. Only an Authorized Participant may engage in creation or redemption transactions directly with the Fund, and none of those Authorized Participants is obligated to engage in creation and/or redemption transactions. The Fund has a limited number of institutions that may act as Authorized Participants on an agency basis (i.e., on behalf of other market participants). To the extent that Authorized Participants exit the business or are unable to proceed with creation or redemption orders with respect to the Fund and no other Authorized Participant is able to step forward to create or redeem, Fund Shares may be more likely to trade at a premium or discount to NAV and possibly face trading halts or delisting. The Fund may also rely on a small number of third-party market makers to provide a market for the purchase and sale of Fund Shares but such market makers are under no obligation to do so. Decisions by Authorized Participants or market makers to reduce their role or step away from these activities in times of market stress could inhibit the effectiveness of the arbitrage process in maintaining the relationship between the underlying values of the Fund’s portfolio securities and the Fund’s market price. Any trading halt or other problem relating to the trading activity of these market makers or any issues disrupting the Authorized Participants’ ability to proceed with creation and/or redemption orders could result in a dramatic change in the spread between the Fund’s net asset value and the price at which Fund Shares are trading on the Exchange, which could result in a decrease in value of Fund Shares. This reduced effectiveness could result in Fund Shares trading at a premium or discount to net asset value and also in greater than normal intraday bid-ask spreads Fund Shares.

 

Cash Transactions Risk. The Fund currently expects to effect a significant portion of its creations and redemptions for cash, rather than in-kind securities. Paying redemption proceeds in cash rather than through in-kind delivery of portfolio securities may require the Fund to dispose of or sell portfolio securities or other assets at an inopportune time to obtain the cash needed to meet redemption orders. This may cause the Fund to sell a security and recognize a capital gain or loss that might not have been incurred if it had made a redemption in-kind. As a result, the Fund may pay out higher or lower annual capital gains distributions than ETFs that redeem in-kind. The use of cash creations and redemptions may also cause the Fund’s Shares to trade in the market at greater bid-ask spreads or greater premiums or discounts to the Fund’s NAV. Furthermore, the Fund may not be able to execute cash transactions for creation and redemption purposes at the same price used to determine the Fund’s NAV. To the extent that the maximum additional charge for creation or redemption transactions is insufficient to cover the execution shortfall, the Fund’s performance could be negatively impacted.

 

Costs of Buying and Selling Fund Shares. Due to the costs of buying or selling Fund Shares, including brokerage commissions imposed by brokers and bid/ask spreads, frequent trading of Fund Shares may significantly reduce investment results and an investment in Fund Shares may not be advisable for investors who anticipate regularly making small investments.

 

Premium/Discount Risk. As with all ETFs, Fund Shares may be bought and sold in the secondary market at market prices. The trading prices of Fund Shares in the secondary market may differ from the Fund’s daily net asset value per share and there may be times when the market price of the shares is more than the net asset value per share (premium) or less than the net asset value per share (discount). If a shareholder purchases Fund Shares at a time when the market price is at a premium to the net asset value or sells Fund Shares at a time when the market price is at a discount to the net asset value, the shareholder may pay more for, or receive less than, the underlying value of the Fund Shares, respectively. This risk is heightened in times of market volatility or periods of steep market declines.

 

Trading Risks. Although Fund Shares are listed for trading on the Exchange and may be traded on U.S. exchanges other than the Exchange, there can be no assurance that Fund Shares will trade with any volume, or at all, on any stock exchange. In stressed market conditions, the liquidity of Fund Shares may begin to mirror the liquidity of the Fund’s underlying portfolio holdings, which can be significantly less liquid than Fund Shares. Trading in Fund Shares on the Exchange may be halted due to market conditions or for reasons that, in the view of the Exchange, make trading in Fund Shares inadvisable. In addition, trading in Fund Shares on the Exchange is subject to trading halts caused by extraordinary market volatility pursuant to the Exchange’s “circuit breaker” rules. There can be no assurance that the requirements of the Exchange necessary to maintain the listing of the Fund will continue to be met or will remain unchanged.

Roundhill Bitcoin WeeklyPay™ ETF | U.S. GOVERNMENT SECURITIES RISK  
Prospectus [Line Items]  
Risk [Text Block]

U.S. GOVERNMENT SECURITIES RISK. U.S. government securities are subject to interest rate risk but generally do not involve the credit risks associated with investments in other types of debt securities. As a result, the yields available from U.S. government securities are generally lower than the yields available from other debt securities. U.S. government securities are guaranteed only as to the timely payment of interest and the payment of principal when held to maturity.

Roundhill Bitcoin WeeklyPay™ ETF | VALUATION RISK  
Prospectus [Line Items]  
Risk [Text Block]

VALUATION RISK. The Fund may hold securities or other assets that may be valued on the basis of factors other than market quotations. This may occur because the asset or security does not trade on a centralized exchange, or in times of market turmoil or reduced liquidity. There are multiple methods that can be used to value a portfolio holding when market quotations are not readily available. The value established for any portfolio holding at a point in time might differ from what would be produced using a different methodology or if it had been priced using market quotations. Portfolio holdings that are valued using techniques other than market quotations, including “fair valued” assets or securities, may be subject to greater fluctuation in their valuations from one day to the next than if market quotations were used. In addition, there is no assurance that the Fund could sell or close out a portfolio position for the value established for it at any time, and it is possible that the Fund would incur a loss because a portfolio position is sold or closed out at a discount to the valuation established by the Fund at that time. The Fund’s ability to value investments may be impacted by technological issues or errors by pricing services or other third-party service providers.

Roundhill Bitcoin WeeklyPay™ ETF | EQUITY SECURITIES RISK  
Prospectus [Line Items]  
Risk [Text Block]

EQUITY SECURITIES RISK. Equity securities are subject to changes in value, and their values may be more volatile than those of other asset classes. Equity securities prices fluctuate for several reasons, including changes in investors’ perceptions of the financial condition of an issuer or the general condition of the relevant equity market, such as market volatility, or when political or economic events affecting an issuer occur. Common stock prices may be particularly sensitive to rising interest rates, as the cost of capital rises and borrowing costs increase. Common stocks generally subject their holders to more risks than preferred stocks and debt securities because common stockholders’ claims are subordinated to those of holders of preferred stocks and debt securities upon the bankruptcy of the issuer.

Roundhill Bitcoin WeeklyPay™ ETF | SWAP AGREEMENTS RISK  
Prospectus [Line Items]  
Risk [Text Block]

SWAP AGREEMENTS RISK. The Fund will utilize swap agreements to derive its exposure to shares of the Bitcoin ETF. Swap agreements may involve greater risks than direct investment in securities as they may be leveraged and are subject to credit risk, counterparty risk and valuation risk. A swap agreement could result in losses if the underlying reference or asset does not perform as anticipated. In addition, many swaps trade over-the-counter and may be considered illiquid. It may not be possible for the Fund to liquidate a swap position at an advantageous time or price, which may result in significant losses.

Roundhill Bitcoin WeeklyPay™ ETF | NEW FUND RISK  
Prospectus [Line Items]  
Risk [Text Block]

NEW FUND RISK. The Fund is a recently organized investment company with a limited operating history. As a result, prospective investors have a limited track record or history on which to base their investment decision.

Roundhill Bitcoin WeeklyPay™ ETF | REGULATED INVESTMENT COMPANY TAX RISKS  
Prospectus [Line Items]  
Risk [Text Block]

REGULATED INVESTMENT COMPANY TAX RISKS. The Fund intends to qualify annually and to elect to be treated as a regulated investment company under the Internal Revenue Code of 1986, as amended (the “Code”). To qualify for the favorable U.S. federal income tax treatment generally accorded to regulated investment companies, the Fund must, among other things, (i) derive in each taxable year at least 90% of its gross income from dividends, interest, payments with respect to securities loans and gains from the sale or other disposition of stock, securities or foreign currencies or other income derived with respect to its business of investing in such stock, securities or currencies, or net income derived from interests in certain publicly traded partnerships; (ii) diversify its holdings so that, at the end of each quarter of the taxable year, (a) at least 50% of the market value of the Fund’s assets is represented by cash and cash items (including receivables), U.S. government securities, the securities of other regulated investment companies and other securities, with such other securities of any one issuer generally limited for the purposes of this calculation to an amount not greater than 5% of the value of the Fund’s total assets and not greater than 10% of the outstanding voting securities of such issuer, and (b) not more than 25% of the value of its total assets is invested in the securities (other than U.S. government securities or the securities of other regulated investment companies) of any one issuer, or two or more issuers which the Fund controls which are engaged in the same, similar or related trades or businesses, or the securities of one or more of certain publicly traded partnerships; and (iii) distribute at least 90% of its investment company taxable income (which includes, among other items, dividends, interest and net short-term capital gains in excess of net long-term capital losses) and at least 90% of its net tax-exempt interest income each taxable year. There are certain exceptions for failure to qualify if the failure is for reasonable cause or is de minimis, and certain corrective action is taken and certain tax payments are made by the Fund.

 

If the Fund were to fail to meet the qualifying income test or asset diversification test and fail to qualify as a RIC, it would be taxed in the same manner as an ordinary corporation, and distributions to its shareholders would not be deductible by the Fund in computing its taxable income, which would adversely affect the Fund’s performance.

Roundhill Bitcoin WeeklyPay™ ETF | LARGE SHAREHOLDER RISK  
Prospectus [Line Items]  
Risk [Text Block]

LARGE SHAREHOLDER RISK. Certain shareholders, including affiliated funds advised by the Adviser, may from time to time own a significant portion of the Fund’s shares. In addition, a third-party investor, the Adviser or an affiliate of the Adviser (“Affiliate”), an authorized participant, a market maker, or another entity may invest in the Fund and hold its investment for a limited period solely to facilitate the commencement of the Fund or to help the Fund achieve a specified size or scale. There can be no assurance that any large shareholder will not redeem its investment, that the size of the Fund will be maintained at such levels, or that the Fund will continue to meet applicable listing requirements. Redemptions by large shareholders could have a significant negative impact on the Fund. In addition, transactions by large shareholders may account for a large percentage of the trading volume on the Fund’s listing exchange and may, therefore, have a material upward or downward effect on the market price of the shares.

 

To the extent that a significant percentage of the Fund’s shares are owned or controlled by a small number of account shareholders (or a single account shareholder), including funds or accounts over which the Adviser or an Affiliate has investment discretion, the Fund is subject to the risk that those shareholders may purchase or redeem Fund shares in significant amounts rapidly or unexpectedly, including as a result of an asset allocation decision made by the Adviser or an Affiliate. This may adversely affect the Fund’s performance if the Adviser is forced to sell portfolio securities or invest cash when it would not otherwise choose to do so. Redemptions of a large number of shares may affect the liquidity of the Fund’s portfolio, increase the Fund’s transaction costs, and accelerate the realization of taxable income and/or gains. In addition, a large redemption could result in the Fund’s current expenses being allocated over a smaller asset base, leading to an increase in the Fund’s gross expense ratio. Large purchases of the Fund’s shares may also adversely affect the Fund’s performance to the extent that the Fund is delayed in investing new cash or otherwise maintains a larger cash position than it ordinarily would, particularly if the Fund accepts cash for an order for the purchase of creation units of the Fund’s shares.

Roundhill Bitcoin WeeklyPay™ ETF | BITCOIN ETF INVESTING RISKS  
Prospectus [Line Items]  
Risk [Text Block]

BITCOIN ETF INVESTING RISKS. The Fund will have significant exposure to the Bitcoin ETF through its investments in shares of the Bitcoin ETF and swap agreements that utilize the Bitcoin ETF as the reference asset. Accordingly, the Fund will subject to the risks of the Bitcoin ETF, set forth below. In addition to these risks, the Bitcoin ETF is also subject to the following risks to which the Fund is also subject, which are described within the section entitled “Principal Risks”: Market Risk, Asset Class Risk, Concentration Risk, Current Market Conditions Risk, Cybersecurity Risk, Equity Securities Risk, Operational Risk and Structural ETF Risk.

 

BITCOIN RISK. Bitcoin remains a volatile and evolving asset subject to significant market fluctuations, uncertainty and speculative investment interest. Although increased institutional adoption and regulatory clarity have recently improved market stability and broader acceptance, the value of bitcoin continues to be influenced substantially by market sentiment, speculative demand and macroeconomic factors rather than traditional fundamental analysis alone. The further development and sustained acceptance of the Bitcoin network are dependent on a variety of complex factors, including technological advancements, regulatory developments, institutional participation and broader public adoption. While regulatory oversight of bitcoin and related digital assets has notably increased, particularly in jurisdictions like the United States and Europe, the global regulatory landscape remains fragmented. Sudden or significant regulatory actions—including new legislation, enforcement actions against key market participants, or policy shifts—can still materially impact bitcoin’s valuation and liquidity. Bitcoin markets remain susceptible to manipulation, fraud, theft, cybersecurity incidents and operational disruptions, especially on trading platforms that lack robust regulatory oversight or proper cybersecurity standards. Furthermore, a significant concentration of bitcoin holdings among a limited number of large holders, often referred to as “whales,” continues to pose risks of price volatility or manipulation through coordinated transactions. Technological risks remain inherent in bitcoin and its underlying blockchain network. While advancements such as Layer 2 scaling solutions (e.g., the Lightning Network) have made meaningful progress toward addressing scalability and usability concerns, these technologies are still evolving and carry risks of technical vulnerabilities, hacking and operational failures that may undermine confidence or negatively affect bitcoin’s value. The potential for blockchain forks, where disagreements among developers and stakeholders lead to competing blockchains, continues to exist. Although fewer contentious forks have occurred in recent times, such events could reoccur, introducing market confusion, diluting value or weakening confidence in the bitcoin blockchain. Competition from alternative blockchain networks and digital assets remains strong. Networks like Ethereum and other blockchain platforms with smart contract capabilities, privacy features or superior scalability may attract broader adoption, thereby reducing bitcoin’s relative attractiveness or limiting its potential as an alternative payment system or digital store of value. Any of these risks, individually or collectively, could materially and adversely affect the acceptance and market value of bitcoin, consequently impacting the value of the Bitcoin ETF or related investment products.

 

CUSTODY RISK. Security breaches, computer malware and computer hacking attacks have been a prevalent concern in relation to digital assets. The bitcoin held by the Bitcoin ETF’s custodian will likely be an appealing target to hackers or malware distributors seeking to destroy, damage or steal the Bitcoin ETF’s bitcoin. To the extent that the Bitcoin ETF and its service providers are unable to identify and mitigate or stop new security threats or otherwise adapt to technological changes in the digital asset industry, the Bitcoin ETF’s bitcoin may be subject to theft, loss, destruction or other attack. The Bitcoin ETF and its sponsor and service providers have put security procedures in place to prevent such theft, loss or destruction, including but not limited to, offline storage, or cold storage, multiple encrypted private key “shards” and other measures. Nevertheless, the security procedures cannot guarantee the prevention of any loss due to a security breach, software defect or act of God that may be borne by the Bitcoin ETF and the security procedures may not protect against all errors, software flaws or other vulnerabilities in the Bitcoin ETF’s technical infrastructure, which could result in theft, loss or damage of its assets. The Bitcoin ETF does not control the operations of its service providers or their implementation of such security procedures, and there can be no assurance that such security procedures will actually work as designed or prove to be successful in safeguarding the Bitcoin ETF’s assets against all possible sources of theft, loss or damage. Assets not held in cold storage, such as assets held in a trading account, may be more vulnerable to security breach, hacking or loss than assets held in cold storage. Furthermore, assets held in a trading account are held on an omnibus rather than segregated basis, which creates greater risk of loss. The security procedures and operational infrastructure may be breached due to the actions of outside parties, error or malfeasance of an employee of the Bitcoin ETF’s service providers, and, as a result, an unauthorized party may obtain access to the Bitcoin ETF’s account at the custodian where its bitcoin is held, the relevant private keys (and therefore bitcoin) or other data or property of the Bitcoin ETF. Additionally, outside parties may attempt to fraudulently induce employees of the Bitcoin ETF or its service providers to disclose sensitive information in order to gain access to the Bitcoin ETF’s infrastructure. As the techniques used to obtain unauthorized access, disable or degrade service, or sabotage systems change frequently, or may be designed to remain dormant until a predetermined event and often are not recognized until launched against a target, the Bitcoin ETF and its service providers may be unable to anticipate these techniques or implement adequate preventative measures.

 

DIGITAL ASSET TRADING PLATFORMS RISK. Digital asset trading platforms remain relatively new and vary significantly in terms of regulation, transparency, operational stability and compliance standards. While certain prominent trading platforms, particularly those based in the United States, have substantially improved transparency, compliance, and regulatory adherence, many platforms still operate internationally or offshore with significantly less stringent oversight. Platforms located outside the United States may be subject to minimal or inconsistent regulatory enforcement and often do not provide sufficient public information regarding their management structure, ownership, financial stability, cybersecurity practices, or compliance controls. Despite increased institutional involvement, enhanced security measures, and more standardized operating practices adopted by leading platforms, digital asset exchanges continue to be vulnerable to cybersecurity threats, hacking incidents, fraudulent activities, operational disruptions and other technical risks. High-profile failures, breaches or shutdowns of major trading platforms or custodians, such as those arising from fraud, cybersecurity incidents, regulatory enforcement actions or insolvency, can significantly reduce investor confidence, increase market volatility and potentially trigger contagion effects across the digital asset ecosystem. Regulatory developments and enforcement actions continue to shape the landscape in which digital asset platforms operate. Recent regulatory scrutiny has heightened globally, particularly in jurisdictions with substantial trading volumes, such as the United States, Europe and Asia. Increased regulatory oversight, while potentially positive for market stability in the long run, can create short-term disruption, reduce liquidity, prompt platform closures or alter business models substantially, thereby affecting the prices of digital assets, including bitcoin. Investors should be aware that trading or custodying bitcoin on less transparent or poorly regulated platforms increases the risk of losing access to digital assets due to platform insolvency, hacking incidents, regulatory intervention or operational failure. Although improvements have been made, the digital asset marketplace remains inherently riskier than traditional financial markets, and investors may have limited recourse if a digital asset trading platform fails or is compromised.

 

IRREVOCABILITY OF TRANSACTIONS RISK. Bitcoin transactions are typically not reversible without the consent and active participation of the recipient of the transaction. Once a transaction has been verified and recorded in a block that is added to the bitcoin blockchain, an incorrect transfer or theft of bitcoin generally will not be reversible, and the Bitcoin ETF may not be capable of seeking compensation for any such transfer or theft. It is possible that, through computer or human error, or through theft or other criminal action, the Bitcoin ETF’s bitcoin could be transferred from the Bitcoin ETF’s account at its custodian in incorrect amounts or to unauthorized third parties, or to uncontrolled accounts.

 

VOLATILITY RISK. The price of bitcoin remains highly volatile and subject to significant price fluctuations. While recent increases in institutional adoption, clearer regulatory frameworks and broader market acceptance have contributed to greater stability relative to earlier periods, the price of bitcoin continues to be influenced by rapid shifts in market sentiment, regulatory developments, macroeconomic conditions, technological advancements and unforeseen events. The market price of bitcoin has historically experienced dramatic highs and lows over short periods, often with limited or no identifiable catalyst. Given the evolving nature of digital asset markets, price volatility may be amplified by external factors such as changes in global financial markets, geopolitical events, regulatory enforcement actions or significant technological or security incidents. Furthermore, speculative trading, leveraged positions and derivatives markets tied to bitcoin continue to contribute to potential volatility. Investors should remain aware that sudden, substantial price movements may occur at any time, potentially leading to significant losses. Consequently, investments linked directly or indirectly to bitcoin, including the Bitcoin ETF, may experience heightened volatility compared to traditional investment products.

NON-DIVERSIFICATION RISK. As a “non-diversified” fund, the Fund may hold a smaller number of portfolio securities than many other funds. To the extent the Fund invests in a relatively small number of issuers, a decline in the market value of a particular security held by the Fund may affect its value more than if it invested in a larger number of issuers. The value of the Fund Shares may be more volatile than the values of shares of more diversified funds.

Roundhill Russell 2000 WeeklyPay™ ETF | MARKET RISK  
Prospectus [Line Items]  
Risk [Text Block]

MARKET RISK. Market risk is the risk that a particular investment, or Fund Shares in general, may fall in value. Securities are subject to market fluctuations caused by real or perceived adverse economic, political, and regulatory factors or market developments, changes in interest rates, disruptions to trade, impositions of tariffs and perceived trends in securities prices. Fund Shares could decline in value or underperform other investments. In addition, local, regional or global events such as war, acts of terrorism, market manipulation, government defaults, government shutdowns, regulatory actions, political changes, diplomatic developments, the imposition of sanctions and other similar measures, spread of infectious diseases or other public health issues, recessions, natural disasters, or other events could have a significant negative impact on the Fund and its investments. Any of such circumstances could have a materially negative impact on the value of Fund Shares, the liquidity of an investment, and may result in increased market volatility. During any such events, Fund Shares may trade at increased premiums or discounts to their net asset value, the bid/ask spread on Fund Shares may widen and the returns on investment may fluctuate.

Roundhill Russell 2000 WeeklyPay™ ETF | LIQUIDITY RISK  
Prospectus [Line Items]  
Risk [Text Block]

LIQUIDITY RISK. The market for swap agreements that reference the Russell 2000 ETF shares may be subject to periods of illiquidity. During such times it may be difficult or impossible to buy or sell a position at the desired price. Market disruptions or volatility can also make it difficult to find a counterparty willing to transact at a reasonable price and sufficient size. Illiquid markets may cause losses, which could be significant. The large size of the positions which the Fund may acquire increases the risk of illiquidity, may make its positions more difficult to liquidate, and may increase the losses incurred while trying to do so. Such large positions also may impact the price of swap agreements on the Russell 2000 ETF shares.

Roundhill Russell 2000 WeeklyPay™ ETF | ACTIVE MANAGEMENT RISK

ACTIVE MANAGEMENT RISK. The Fund is actively-managed and its performance reflects investment decisions that the Adviser and/or Sub-Adviser makes for the Fund. Such judgments about the Fund’s investments may prove to be incorrect. If the investments selected and the strategies employed by the Fund fail to produce the intended results, the Fund could underperform as compared to other funds with similar investment objectives and/or strategies, or could have negative returns.

ACTIVE MARKET RISK. Although Fund Shares are listed for trading on the Exchange, there can be no assurance that an active trading market for Fund Shares will develop or be maintained. Fund Shares trade on the Exchange at market prices that may be below, at or above the Fund’s net asset value. Securities, including Fund Shares, are subject to market fluctuations and liquidity constraints that may be caused by such factors as economic, political, or regulatory developments, changes in interest rates, and/or perceived trends in securities prices. Fund Shares could decline in value or underperform other investments.

CONCENTRATION RISK. The Fund is susceptible to an increased risk of loss, including losses due to adverse events that affect the Fund’s investments more than the market as a whole, to the extent that the Fund’s investments are concentrated in investments that provide exposure to the Russell 2000 ETF and the industry or group of industries to which it is concentrated.

COUNTERPARTY RISK. Fund transactions involving a counterparty are subject to the risk that the counterparty will not fulfill its obligation to the Fund. Counterparty risk may arise because of the counterparty’s financial condition (i.e., financial difficulties, bankruptcy, or insolvency), market activities and developments, or other reasons, whether foreseen or not. A counterparty’s inability to fulfill its obligation may result in significant financial loss to the Fund. The Fund may be unable to recover its investment from the counterparty or may obtain a limited recovery, and/or recovery may be delayed.

Roundhill Russell 2000 WeeklyPay™ ETF | CURRENT MARKET CONDITIONS RISK  
Prospectus [Line Items]  
Risk [Text Block]

CURRENT MARKET CONDITIONS RISK. Current market conditions risk is the risk that a particular investment, or Fund Shares in general, may fall in value due to current market conditions. As a means to fight inflation, which remains at elevated levels, the Federal Reserve and certain foreign central banks have raised interest rates; however, the Federal Reserve has recently lowered interest rates and may continue to do so. U.S. regulators have proposed several changes to market and issuer regulations which would directly impact the Fund, and any regulatory changes could adversely impact the Fund’s ability to achieve its investment strategies or make certain investments. Recent and potential future bank failures could result in disruption to the broader banking industry or markets generally and reduce confidence in financial institutions and the economy as a whole, which may also heighten market volatility and reduce liquidity. Additionally, challenges in commercial real estate markets, including rising interest rates, declining valuations and increasing vacancies, could have a broader impact on financial markets. The ongoing adversarial political climate in the United States, as well as political and diplomatic events both domestic and abroad, have and may continue to have an adverse impact the U.S. regulatory landscape, markets and investor behavior, which could have a negative impact on the Fund’s investments and operations. The change in administration resulting from the 2024 United States national elections could result in significant impacts to international trade relations, tax and immigration policies, and other aspects of the national and international political and financial landscape, which could affect, among other things, inflation and the securities markets generally. Other unexpected political, regulatory and diplomatic events within the U.S. and abroad may affect investor and consumer confidence and may adversely impact financial markets and the broader economy. For example, ongoing armed conflicts between Russia and Ukraine in Europe and among Israel, Iran, Hamas and other militant groups in the Middle East, have caused and could continue to cause significant market disruptions and volatility within the markets in Russia, Europe, the Middle East and the United States. The hostilities and sanctions resulting from those hostilities have and could continue to have a significant impact on certain Fund investments as well as Fund performance and liquidity. The economies of the United States and its trading partners, as well as the financial markets generally, may be adversely impacted by trade disputes, including the imposition of tariffs, and other matters. For example, the United States has imposed trade barriers and restrictions on China. In addition, the Chinese government is engaged in a longstanding dispute with Taiwan, continually threatening an invasion. If the political climate between the United States and China does not improve or continues to deteriorate, if China were to attempt invading Taiwan, or if other geopolitical conflicts develop or worsen, economies, markets and individual securities may be adversely affected, and the value of the Fund’s assets may go down. A public health crisis and the ensuing policies enacted by governments and central banks may cause significant volatility and uncertainty in global financial markets, negatively impacting global growth prospects. As the COVID-19 global pandemic illustrated, such events may affect certain geographic regions, countries, sectors and industries more significantly than others. Advancements in technology may also adversely impact markets and the overall performance of the Fund. For instance, the economy may be significantly impacted by the advanced development and increased regulation of artificial intelligence. Additionally, cyber security breaches of both government and non-government entities could have negative impacts on infrastructure and the ability of such entities, including the Fund, to operate properly. These events, and any other future events, may adversely affect the prices and liquidity of the Fund’s portfolio investments and could result in disruptions in the trading markets.

Roundhill Russell 2000 WeeklyPay™ ETF | CYBERSECURITY RISK  
Prospectus [Line Items]  
Risk [Text Block]

CYBERSECURITY RISK. Failures or breaches of the electronic systems of the Fund, the Fund’s adviser, sub-adviser, distributor and other service providers, market makers, Authorized Participants or the issuers of securities in which the Fund invests have the ability to cause disruptions, negatively impact the Fund’s business operations and/or potentially result in financial losses to the Fund and its shareholders. While the Fund has established business continuity plans and risk management systems seeking to address system breaches or failures, there are inherent limitations in such plans and systems. Furthermore, the Fund cannot control the cybersecurity plans and systems of the Fund’s other service providers, market makers, Authorized Participants or issuers of securities in which the Fund invests.

Roundhill Russell 2000 WeeklyPay™ ETF | DEBT SECURITIES RISK  
Prospectus [Line Items]  
Risk [Text Block]

DEBT SECURITIES RISK. Investments in debt securities subject the holder to the credit risk of the issuer. Credit risk refers to the possibility that the issuer or other obligor of a security will not be able or willing to make payments of interest and principal when due. Generally, the value of debt securities will change inversely with changes in interest rates. To the extent that interest rates rise, certain underlying obligations may be paid off substantially slower than originally anticipated and the value of those securities may fall sharply. During periods of falling interest rates, the income received by the Fund may decline. If the principal on a debt security is prepaid before expected, the prepayments of principal may have to be reinvested in obligations paying interest at lower rates. Debt securities generally do not trade on a securities exchange making them generally less liquid and more difficult to value than common stock.

Roundhill Russell 2000 WeeklyPay™ ETF | DERIVATIVES RISK  
Prospectus [Line Items]  
Risk [Text Block]

DERIVATIVES RISK. The use of derivative instruments involves risks different from, or possibly greater than, the risks associated with investing directly in securities and other traditional investments. These risks include: (i) the risk that the counterparty to a derivative transaction may not fulfill its contractual obligations; (ii) risk of mispricing or improper valuation; and (iii) the risk that changes in the value of the derivative may not correlate perfectly with the underlying asset. Derivative prices are highly volatile and may fluctuate substantially during a short period of time. Such prices are influenced by numerous factors that affect the markets, including, but not limited to: changing supply and demand relationships; government programs and policies; national and international political and economic events, changes in interest rates, inflation and deflation and changes in supply and demand relationships. Trading derivative instruments involves risks different from, or possibly greater than, the risks associated with investing directly in securities. Derivative contracts ordinarily have leverage inherent in their terms. The use of leverage may cause the Fund to liquidate portfolio positions when it would not be advantageous to do so in order to satisfy its obligations or to meet regulatory or contractual requirements for derivatives. The use of derivatives can magnify potential for gain or loss and, therefore, amplify the effects of market volatility on share price.

Roundhill Russell 2000 WeeklyPay™ ETF | DISTRIBUTION TAX RISK  
Prospectus [Line Items]  
Risk [Text Block]

DISTRIBUTION TAX RISK. The Fund currently expects to make distributions on a weekly basis. Such frequent distributions may expose investors to increased tax liabilities. However, these distributions may exceed the Fund’s income and gains for the Fund’s taxable year. Distributions in excess of the Fund’s current and accumulated earnings and profits will be treated as a return of capital. A return of capital distribution generally will not be taxable but will reduce the shareholder’s cost basis and will result in a higher capital gain or lower capital loss when those Fund Shares on which the distribution was received are sold. Once a Fund shareholder’s cost basis is reduced to zero, further distributions will be treated as capital gain if the Fund shareholder holds Fund Shares as capital assets. Additionally, any capital returned through distributions will be distributed after payment of Fund fees and expenses. Because a portion of the Fund’s distributions may consist of return of capital, the Fund may not be an appropriate investment for investors who do not want their principal investment in the Fund to decrease over time or who do not wish to receive return of capital in a given period. In the event that a shareholder purchases Fund Shares shortly before a distribution by the Fund, the entire distribution may be taxable to the shareholder even though a portion of the distribution effectively represents a return of the purchase price.

Roundhill Russell 2000 WeeklyPay™ ETF | ETF RISK  
Prospectus [Line Items]  
Risk [Text Block]

ETF RISK. The Fund may invest in ETFs. The value of an ETF held by the Fund will fluctuate over time based on fluctuations in the values of the assets held by the ETF, which may be affected by changes in general economic conditions, expectations for future growth and profits, interest rates and the supply and demand for those assets. When the Fund invests in an ETF, it will bear a proportionate share of the ETF’s expenses. Brokerage, tax and other expenses may negatively impact the performance of the ETF and, in turn, the value of the Fund Shares. An ETF that tracks an index may not exactly match the performance of the index due to cash drag, differences between the portfolio of the ETF and the components of the index, expenses and other factors.

Roundhill Russell 2000 WeeklyPay™ ETF | INFLATION RISK

Risk [Text Block]

INFLATION RISK. Inflation risk is the risk that the value of assets or income from investments will be less in the future as inflation decreases the value of money. As inflation increases, the present value of the Fund’s assets and distributions may decline. This risk is more prevalent with respect to fixed income securities held by the Fund.

Roundhill Russell 2000 WeeklyPay™ ETF | Interest Rate Risk [Member]  
Prospectus [Line Items]  
Risk [Text Block]

INTEREST RATE RISK. Interest rate risk is the risk that the value of the debt securities in the Fund’s portfolio will decline because of rising market interest rates. Interest rate risk is generally lower for shorter term debt securities and higher for longer-term debt securities. Duration is a reasonably accurate measure of a debt security’s price sensitivity to changes in interest rates and a common measure of interest rate risk. Duration measures a debt security’s expected life on a present value basis, taking into account the debt security’s yield, interest payments and final maturity. In general, duration represents the expected percentage change in the value of a security for an immediate 1% change in interest rates. For example, the price of a debt security with a three-year duration would be expected to drop by approximately 3% in response to a 1% increase in interest rates. Therefore, prices of debt securities with shorter durations tend to be less sensitive to interest rate changes than debt securities with longer durations. As the value of a debt security changes over time, so will its duration.

Roundhill Russell 2000 WeeklyPay™ ETF | LEGISLATION AND LITIGATION RISK  
Prospectus [Line Items]  
Risk [Text Block]

LEGISLATION AND LITIGATION RISK. Legislation or litigation that affects the value of assets or securities held by the Fund may reduce the value of the Fund. From time to time, various legislative initiatives are proposed that may have a negative impact on certain assets or securities in which the Fund invests. In addition, litigation regarding any of the assets or securities owned by the Fund may negatively impact the value of the Shares. Such legislation or litigation may cause the Fund to lose value or may result in higher portfolio turnover if the Adviser determines to sell such a holding.

Roundhill Russell 2000 WeeklyPay™ ETF | LEVERAGE RISK  
Prospectus [Line Items]  
Risk [Text Block]

LEVERAGE RISK. The Fund obtains investment exposure in excess of its net assets by utilizing leverage and may lose more money in market conditions that are adverse to its investment objectives than a fund that does not utilize leverage. An investment in the Fund is exposed to the risk that a decline in the weekly performance of shares of the Russell 2000 ETF will be magnified. This means that an investment in the Fund will be reduced by an amount equal to 1.2% for every 1% weekly decline in the market value of the Russell 2000 ETF shares, not including the costs of financing leverage and other operating expenses, which would further reduce its value. The Fund could theoretically lose an amount greater than its net assets in the event the market value of the Russell 2000 ETF shares decline more than 83.33% over a calendar week. Leverage will also have the effect of magnifying any differences in the Fund’s correlation with the Russell 2000 ETF shares.

Roundhill Russell 2000 WeeklyPay™ ETF | MONEY MARKET INSTRUMENTS RISK  
Prospectus [Line Items]  
Risk [Text Block]

MONEY MARKET INSTRUMENTS RISK. The value of money market instruments may be affected by changing interest rates and by changes in the credit ratings of the investments. If a significant amount of the Fund’s assets are invested in money market instruments, it will be more difficult for the Fund to achieve its investment objectives. An investment in a money market fund is not insured or guaranteed by the FDIC or any other government agency. It is possible to lose money by investing in a money market fund.

Roundhill Russell 2000 WeeklyPay™ ETF | OPERATIONAL RISK  
Prospectus [Line Items]  
Risk [Text Block]

OPERATIONAL RISK. The Fund is subject to risks arising from various operational factors, including, but not limited to, human error, processing and communication errors, errors of the Fund’s service providers, counterparties or other third-parties, failed or inadequate processes and technology or systems failures. The Fund relies on third-parties for a range of services, including custody. Any delay or failure relating to engaging or maintaining such service providers may affect the Fund’s ability to meet its investment objectives. Although the Fund and the Adviser seek to reduce these operational risks through controls and procedures, there is no way to completely protect against such risks.

Roundhill Russell 2000 WeeklyPay™ ETF | SPECIAL TAX RISK  
Prospectus [Line Items]  
Risk [Text Block]

SPECIAL TAX RISK. The Fund intends to qualify annually and to elect to be treated as a regulated investment company under the Internal Revenue Code of 1986, as amended (the “Code”). To qualify for the favorable U.S. federal income tax treatment generally accorded to regulated investment companies, the Fund must, among other things, (i) derive in each taxable year at least 90% of its gross income from dividends, interest, payments with respect to securities loans and gains from the sale or other disposition of stock, securities or foreign currencies or other income derived with respect to its business of investing in such stock, securities or currencies, or net income derived from interests in certain publicly traded partnerships; (ii) diversify its holdings so that, at the end of each quarter of the taxable year, (a) at least 50% of the market value of the Fund’s assets is represented by cash and cash items (including receivables), U.S. government securities, the securities of other regulated investment companies and other securities, with such other securities of any one issuer generally limited for the purposes of this calculation to an amount not greater than 5% of the value of the Fund’s total assets and not greater than 10% of the outstanding voting securities of such issuer, and (b) not more than 25% of the value of its total assets is invested in the securities (other than U.S. government securities or the securities of other regulated investment companies) of any one issuer, or two or more issuers which the Fund controls which are engaged in the same, similar or related trades or businesses, or the securities of one or more of certain publicly traded partnerships; and (iii) distribute at least 90% of its investment company taxable income (which includes, among other items, dividends, interest and net short-term capital gains in excess of net long-term capital losses) and at least 90% of its net tax-exempt interest income each taxable year. There are certain exceptions for failure to qualify if the failure is for reasonable cause or is de minimis, and certain corrective action is taken and certain tax payments are made by the Fund.

 

The authority with regard to swaps entered into by regulated investment companies is unclear both as to the qualification under the income test and the identification of the issuer under the diversification test. The Fund intends to take the position that because the swaps held by the Fund reference securities that the income on the swaps are “other income” from the Fund’s business of investing in stocks and securities. In addition, the Fund intends to manage its investments in the swaps so that neither the exposure to issuer of the referenced security nor the exposure to any one counterparty of the swaps will exceed 25% of the gross value of the Fund’s portfolio at the end of any quarter.

 

If the Fund were to fail to meet the qualifying income test or asset diversification test and fail to qualify as a RIC, it would be taxed in the same manner as an ordinary corporation, and distributions to its shareholders would not be deductible by the Fund in computing its taxable income, which would adversely affect the Fund’s performance.

Roundhill Russell 2000 WeeklyPay™ ETF | STRUCTURAL ETF RISKS  
Prospectus [Line Items]  
Risk [Text Block]

STRUCTURAL ETF RISKS. The Fund is an ETF. Accordingly, it is subject to certain risks associated with its unique structure.

 

Market Participants Risk. Only an Authorized Participant may engage in creation or redemption transactions directly with the Fund, and none of those Authorized Participants is obligated to engage in creation and/or redemption transactions. The Fund has a limited number of institutions that may act as Authorized Participants on an agency basis (i.e., on behalf of other market participants). To the extent that Authorized Participants exit the business or are unable to proceed with creation or redemption orders with respect to the Fund and no other Authorized Participant is able to step forward to create or redeem, Fund Shares may be more likely to trade at a premium or discount to NAV and possibly face trading halts or delisting. The Fund may also rely on a small number of third-party market makers to provide a market for the purchase and sale of Fund Shares but such market makers are under no obligation to do so. Decisions by Authorized Participants or market makers to reduce their role or step away from these activities in times of market stress could inhibit the effectiveness of the arbitrage process in maintaining the relationship between the underlying values of the Fund’s portfolio securities and the Fund’s market price. Any trading halt or other problem relating to the trading activity of these market makers or any issues disrupting the Authorized Participants’ ability to proceed with creation and/or redemption orders could result in a dramatic change in the spread between the Fund’s net asset value and the price at which Fund Shares are trading on the Exchange, which could result in a decrease in value of Fund Shares. This reduced effectiveness could result in Fund Shares trading at a premium or discount to net asset value and also in greater than normal intraday bid-ask spreads Fund Shares.

 

Cash Transactions Risk. The Fund currently expects to effect a significant portion of its creations and redemptions for cash, rather than in-kind securities. Paying redemption proceeds in cash rather than through in-kind delivery of portfolio securities may require the Fund to dispose of or sell portfolio securities or other assets at an inopportune time to obtain the cash needed to meet redemption orders. This may cause the Fund to sell a security and recognize a capital gain or loss that might not have been incurred if it had made a redemption in-kind. As a result, the Fund may pay out higher or lower annual capital gains distributions than ETFs that redeem in-kind. The use of cash creations and redemptions may also cause the Fund’s Shares to trade in the market at greater bid-ask spreads or greater premiums or discounts to the Fund’s NAV. Furthermore, the Fund may not be able to execute cash transactions for creation and redemption purposes at the same price used to determine the Fund’s NAV. To the extent that the maximum additional charge for creation or redemption transactions is insufficient to cover the execution shortfall, the Fund’s performance could be negatively impacted.

 

Costs of Buying and Selling Fund Shares. Due to the costs of buying or selling Fund Shares, including brokerage commissions imposed by brokers and bid/ask spreads, frequent trading of Fund Shares may significantly reduce investment results and an investment in Fund Shares may not be advisable for investors who anticipate regularly making small investments.

 

Premium/Discount Risk. As with all ETFs, Fund Shares may be bought and sold in the secondary market at market prices. The trading prices of Fund Shares in the secondary market may differ from the Fund’s daily net asset value per share and there may be times when the market price of the shares is more than the net asset value per share (premium) or less than the net asset value per share (discount). If a shareholder purchases Fund Shares at a time when the market price is at a premium to the net asset value or sells Fund Shares at a time when the market price is at a discount to the net asset value, the shareholder may pay more for, or receive less than, the underlying value of the Fund Shares, respectively. This risk is heightened in times of market volatility or periods of steep market declines.

 

Trading Risks. Although Fund Shares are listed for trading on the Exchange and may be traded on U.S. exchanges other than the Exchange, there can be no assurance that Fund Shares will trade with any volume, or at all, on any stock exchange. In stressed market conditions, the liquidity of Fund Shares may begin to mirror the liquidity of the Fund’s underlying portfolio holdings, which can be significantly less liquid than Fund Shares. Trading in Fund Shares on the Exchange may be halted due to market conditions or for reasons that, in the view of the Exchange, make trading in Fund Shares inadvisable. In addition, trading in Fund Shares on the Exchange is subject to trading halts caused by extraordinary market volatility pursuant to the Exchange’s “circuit breaker” rules. There can be no assurance that the requirements of the Exchange necessary to maintain the listing of the Fund will continue to be met or will remain unchanged.

Roundhill Russell 2000 WeeklyPay™ ETF | U.S. GOVERNMENT SECURITIES RISK  
Prospectus [Line Items]  
Risk [Text Block]

U.S. GOVERNMENT SECURITIES RISK. U.S. government securities are subject to interest rate risk but generally do not involve the credit risks associated with investments in other types of debt securities. As a result, the yields available from U.S. government securities are generally lower than the yields available from other debt securities. U.S. government securities are guaranteed only as to the timely payment of interest and the payment of principal when held to maturity.

Roundhill Russell 2000 WeeklyPay™ ETF | VALUATION RISK  
Prospectus [Line Items]  
Risk [Text Block]

VALUATION RISK. The Fund may hold securities or other assets that may be valued on the basis of factors other than market quotations. This may occur because the asset or security does not trade on a centralized exchange, or in times of market turmoil or reduced liquidity. There are multiple methods that can be used to value a portfolio holding when market quotations are not readily available. The value established for any portfolio holding at a point in time might differ from what would be produced using a different methodology or if it had been priced using market quotations. Portfolio holdings that are valued using techniques other than market quotations, including “fair valued” assets or securities, may be subject to greater fluctuation in their valuations from one day to the next than if market quotations were used. In addition, there is no assurance that the Fund could sell or close out a portfolio position for the value established for it at any time, and it is possible that the Fund would incur a loss because a portfolio position is sold or closed out at a discount to the valuation established by the Fund at that time. The Fund’s ability to value investments may be impacted by technological issues or errors by pricing services or other third-party service providers.

Roundhill Russell 2000 WeeklyPay™ ETF | EQUITY SECURITIES RISK  
Prospectus [Line Items]  
Risk [Text Block]

EQUITY SECURITIES RISK. Equity securities are subject to changes in value, and their values may be more volatile than those of other asset classes. Equity securities prices fluctuate for several reasons, including changes in investors’ perceptions of the financial condition of an issuer or the general condition of the relevant equity market, such as market volatility, or when political or economic events affecting an issuer occur. Common stock prices may be particularly sensitive to rising interest rates, as the cost of capital rises and borrowing costs increase. Common stocks generally subject their holders to more risks than preferred stocks and debt securities because common stockholders’ claims are subordinated to those of holders of preferred stocks and debt securities upon the bankruptcy of the issuer.

Roundhill Russell 2000 WeeklyPay™ ETF | SWAP AGREEMENTS RISK  
Prospectus [Line Items]  
Risk [Text Block]

SWAP AGREEMENTS RISK. The Fund will utilize swap agreements to derive its exposure to shares of the Russell 2000 ETF. Swap agreements may involve greater risks than direct investment in securities as they may be leveraged and are subject to credit risk, counterparty risk and valuation risk. A swap agreement could result in losses if the underlying reference or asset does not perform as anticipated. In addition, many swaps trade over-the-counter and may be considered illiquid. It may not be possible for the Fund to liquidate a swap position at an advantageous time or price, which may result in significant losses.

Roundhill Russell 2000 WeeklyPay™ ETF | NEW FUND RISK

NEW FUND RISK. The Fund is a recently organized investment company with a limited operating history. As a result, prospective investors have a limited track record or history on which to base their investment decision.

Prospectus [Line Items]  
Risk [Text Block]

REGULATED INVESTMENT COMPANY TAX RISKS. The Fund intends to qualify annually and to elect to be treated as a regulated investment company under the Internal Revenue Code of 1986, as amended (the “Code”). To qualify for the favorable U.S. federal income tax treatment generally accorded to regulated investment companies, the Fund must, among other things, (i) derive in each taxable year at least 90% of its gross income from dividends, interest, payments with respect to securities loans and gains from the sale or other disposition of stock, securities or foreign currencies or other income derived with respect to its business of investing in such stock, securities or currencies, or net income derived from interests in certain publicly traded partnerships; (ii) diversify its holdings so that, at the end of each quarter of the taxable year, (a) at least 50% of the market value of the Fund’s assets is represented by cash and cash items (including receivables), U.S. government securities, the securities of other regulated investment companies and other securities, with such other securities of any one issuer generally limited for the purposes of this calculation to an amount not greater than 5% of the value of the Fund’s total assets and not greater than 10% of the outstanding voting securities of such issuer, and (b) not more than 25% of the value of its total assets is invested in the securities (other than U.S. government securities or the securities of other regulated investment companies) of any one issuer, or two or more issuers which the Fund controls which are engaged in the same, similar or related trades or businesses, or the securities of one or more of certain publicly traded partnerships; and (iii) distribute at least 90% of its investment company taxable income (which includes, among other items, dividends, interest and net short-term capital gains in excess of net long-term capital losses) and at least 90% of its net tax-exempt interest income each taxable year. There are certain exceptions for failure to qualify if the failure is for reasonable cause or is de minimis, and certain corrective action is taken and certain tax payments are made by the Fund.

 

If the Fund were to fail to meet the qualifying income test or asset diversification test and fail to qualify as a RIC, it would be taxed in the same manner as an ordinary corporation, and distributions to its shareholders would not be deductible by the Fund in computing its taxable income, which would adversely affect the Fund’s performance.

Roundhill Russell 2000 WeeklyPay™ ETF | LARGE SHAREHOLDER RISK  
Prospectus [Line Items]  
Risk [Text Block]

LARGE SHAREHOLDER RISK. Certain shareholders, including affiliated funds advised by the Adviser, may from time to time own a significant portion of the Fund’s shares. In addition, a third-party investor, the Adviser or an affiliate of the Adviser (“Affiliate”), an authorized participant, a market maker, or another entity may invest in the Fund and hold its investment for a limited period solely to facilitate the commencement of the Fund or to help the Fund achieve a specified size or scale. There can be no assurance that any large shareholder will not redeem its investment, that the size of the Fund will be maintained at such levels, or that the Fund will continue to meet applicable listing requirements. Redemptions by large shareholders could have a significant negative impact on the Fund. In addition, transactions by large shareholders may account for a large percentage of the trading volume on the Fund’s listing exchange and may, therefore, have a material upward or downward effect on the market price of the shares.

 

To the extent that a significant percentage of the Fund’s shares are owned or controlled by a small number of account shareholders (or a single account shareholder), including funds or accounts over which the Adviser or an Affiliate has investment discretion, the Fund is subject to the risk that those shareholders may purchase or redeem Fund shares in significant amounts rapidly or unexpectedly, including as a result of an asset allocation decision made by the Adviser or an Affiliate. This may adversely affect the Fund’s performance if the Adviser is forced to sell portfolio securities or invest cash when it would not otherwise choose to do so. Redemptions of a large number of shares may affect the liquidity of the Fund’s portfolio, increase the Fund’s transaction costs, and accelerate the realization of taxable income and/or gains. In addition, a large redemption could result in the Fund’s current expenses being allocated over a smaller asset base, leading to an increase in the Fund’s gross expense ratio. Large purchases of the Fund’s shares may also adversely affect the Fund’s performance to the extent that the Fund is delayed in investing new cash or otherwise maintains a larger cash position than it ordinarily would, particularly if the Fund accepts cash for an order for the purchase of creation units of the Fund’s shares.

Roundhill Russell 2000 WeeklyPay™ ETF | RUSSELL 2000 ETF INVESTING RISKS

RUSSELL 2000 ETF INVESTING RISKS. The Fund will have significant exposure to the Russell 2000 ETF through its investments in shares of the Russell 2000 ETF and swap agreements that utilize the Russell 2000 ETF as the reference asset. Accordingly, the Fund will subject to the risks of the Russell 2000 ETF, set forth below. In addition to these risks, the Russell 2000 ETF is also subject to the following risks to which the Fund is also subject, which are described within the section entitled “Principal Risks”: Market Risk, Asset Class Risk, Concentration Risk, Current Market Conditions Risk, Cybersecurity Risk, Equity Securities Risk, Operational Risk and Structural ETF Risk.

 

INDEX-RELATED RISK. The Russell 2000 ETF Index Provider may rely on various sources of information to assess the criteria of components of the Russell 2000 ETF Index, including information that may be based on assumptions and estimates. Neither the Russell 2000 ETF nor its investment adviser offer assurances that the Russell 2000 ETF Index Provider’s methodology or sources of information will provide an accurate assessment of included components or will result in the Russell 2000 ETF meeting its investment objective. Errors in index data, index computations or the construction of the Russell 2000 ETF Index in accordance with its methodology may occur, and the Russell 2000 ETF Index Provider may not identify or correct them promptly or at all, which may have an adverse impact on the Russell 2000 ETF and its shareholders. Unusual market conditions or other unforeseen circumstances (such as natural disasters, political unrest or war) may impact the Russell 2000 ETF Index Provider or a third-party data provider and could cause the Russell 2000 ETF Index Provider to postpone a scheduled rebalance. This could cause the Russell 2000 ETF Index to vary from its normal or expected composition.

 

INDIRECT INVESTMENT RISK. The Russell 2000 ETF is not affiliated with the Trust, the Fund, the Adviser, the Sub-Adviser or any affiliates thereof and is not involved with this offering in any way, and has no obligation to consider the Fund in taking any actions that might affect the value of the Fund. The Trust, the Fund, the Adviser, the Sub-Adviser or any affiliate are not responsible for the performance of the Russell 2000 ETF and make no representation as to the performance of the Russell 2000 ETF. Investing in the Fund is not equivalent to investing in the Russell 2000 ETF Fund shareholders will not have voting rights or rights to receive dividends or other distributions or any other rights with respect to the Russell 2000 ETF.

 

SMALL CAPITALIZATION COMPANIES RISK. Compared to mid- and large-capitalization companies, small-capitalization companies may be less stable and more susceptible to adverse developments. The securities of small-capitalization companies may be more volatile and less liquid than those of mid- and large-capitalization companies. As a result, the Russell 2000 ETF’s share price may be more volatile than that of a fund with a greater investment in large- or mid-capitalization stocks.

 

UNITED STATES RISK. Certain changes in the U.S. economy, such as when the U.S. economy weakens or when its financial markets decline, may have an adverse effect on the securities to which the Fund has exposure.

NON-DIVERSIFICATION RISK. As a “non-diversified” fund, the Fund may hold a smaller number of portfolio securities than many other funds. To the extent the Fund invests in a relatively small number of issuers, a decline in the market value of a particular security held by the Fund may affect its value more than if it invested in a larger number of issuers. The value of the Fund Shares may be more volatile than the values of shares of more diversified funds.

Roundhill Innovation-100 WeeklyPay™ ETF | MARKET RISK  
Prospectus [Line Items]  
Risk [Text Block]

MARKET RISK. Market risk is the risk that a particular investment, or Fund Shares in general, may fall in value. Securities are subject to market fluctuations caused by real or perceived adverse economic, political, and regulatory factors or market developments, changes in interest rates, disruptions to trade, impositions of tariffs and perceived trends in securities prices. Fund Shares could decline in value or underperform other investments. In addition, local, regional or global events such as war, acts of terrorism, market manipulation, government defaults, government shutdowns, regulatory actions, political changes, diplomatic developments, the imposition of sanctions and other similar measures, spread of infectious diseases or other public health issues, recessions, natural disasters, or other events could have a significant negative impact on the Fund and its investments. Any of such circumstances could have a materially negative impact on the value of Fund Shares, the liquidity of an investment, and may result in increased market volatility. During any such events, Fund Shares may trade at increased premiums or discounts to their net asset value, the bid/ask spread on Fund Shares may widen and the returns on investment may fluctuate.

Roundhill Innovation-100 WeeklyPay™ ETF | LIQUIDITY RISK  
Prospectus [Line Items]  
Risk [Text Block]

LIQUIDITY RISK. The market for swap agreements that reference the Innovation-100 ETF shares may be subject to periods of illiquidity. During such times it may be difficult or impossible to buy or sell a position at the desired price. Market disruptions or volatility can also make it difficult to find a counterparty willing to transact at a reasonable price and sufficient size. Illiquid markets may cause losses, which could be significant. The large size of the positions which the Fund may acquire increases the risk of illiquidity, may make its positions more difficult to liquidate, and may increase the losses incurred while trying to do so. Such large positions also may impact the price of swap agreements on the Innovation-100 ETF shares.

Roundhill Innovation-100 WeeklyPay™ ETF | ACTIVE MANAGEMENT RISK

ACTIVE MANAGEMENT RISK. The Fund is actively-managed and its performance reflects investment decisions that the Adviser and/or Sub-Adviser makes for the Fund. Such judgments about the Fund’s investments may prove to be incorrect. If the investments selected and the strategies employed by the Fund fail to produce the intended results, the Fund could underperform as compared to other funds with similar investment objectives and/or strategies, or could have negative returns.

ACTIVE MARKET RISK. Although Fund Shares are listed for trading on the Exchange, there can be no assurance that an active trading market for Fund Shares will develop or be maintained. Fund Shares trade on the Exchange at market prices that may be below, at or above the Fund’s net asset value. Securities, including Fund Shares, are subject to market fluctuations and liquidity constraints that may be caused by such factors as economic, political, or regulatory developments, changes in interest rates, and/or perceived trends in securities prices. Fund Shares could decline in value or underperform other investments.

COUNTERPARTY RISK. Fund transactions involving a counterparty are subject to the risk that the counterparty will not fulfill its obligation to the Fund. Counterparty risk may arise because of the counterparty’s financial condition (i.e., financial difficulties, bankruptcy, or insolvency), market activities and developments, or other reasons, whether foreseen or not. A counterparty’s inability to fulfill its obligation may result in significant financial loss to the Fund. The Fund may be unable to recover its investment from the counterparty or may obtain a limited recovery, and/or recovery may be delayed.

Roundhill Innovation-100 WeeklyPay™ ETF | CURRENT MARKET CONDITIONS RISK  
Prospectus [Line Items]  
Risk [Text Block]

CURRENT MARKET CONDITIONS RISK. Current market conditions risk is the risk that a particular investment, or Fund Shares in general, may fall in value due to current market conditions. As a means to fight inflation, which remains at elevated levels, the Federal Reserve and certain foreign central banks have raised interest rates; however, the Federal Reserve has recently lowered interest rates and may continue to do so. U.S. regulators have proposed several changes to market and issuer regulations which would directly impact the Fund, and any regulatory changes could adversely impact the Fund’s ability to achieve its investment strategies or make certain investments. Recent and potential future bank failures could result in disruption to the broader banking industry or markets generally and reduce confidence in financial institutions and the economy as a whole, which may also heighten market volatility and reduce liquidity. Additionally, challenges in commercial real estate markets, including rising interest rates, declining valuations and increasing vacancies, could have a broader impact on financial markets. The ongoing adversarial political climate in the United States, as well as political and diplomatic events both domestic and abroad, have and may continue to have an adverse impact the U.S. regulatory landscape, markets and investor behavior, which could have a negative impact on the Fund’s investments and operations. The change in administration resulting from the 2024 United States national elections could result in significant impacts to international trade relations, tax and immigration policies, and other aspects of the national and international political and financial landscape, which could affect, among other things, inflation and the securities markets generally. Other unexpected political, regulatory and diplomatic events within the U.S. and abroad may affect investor and consumer confidence and may adversely impact financial markets and the broader economy. For example, ongoing armed conflicts between Russia and Ukraine in Europe and among Israel, Iran, Hamas and other militant groups in the Middle East, have caused and could continue to cause significant market disruptions and volatility within the markets in Russia, Europe, the Middle East and the United States. The hostilities and sanctions resulting from those hostilities have and could continue to have a significant impact on certain Fund investments as well as Fund performance and liquidity. The economies of the United States and its trading partners, as well as the financial markets generally, may be adversely impacted by trade disputes, including the imposition of tariffs, and other matters. For example, the United States has imposed trade barriers and restrictions on China. In addition, the Chinese government is engaged in a longstanding dispute with Taiwan, continually threatening an invasion. If the political climate between the United States and China does not improve or continues to deteriorate, if China were to attempt invading Taiwan, or if other geopolitical conflicts develop or worsen, economies, markets and individual securities may be adversely affected, and the value of the Fund’s assets may go down. A public health crisis and the ensuing policies enacted by governments and central banks may cause significant volatility and uncertainty in global financial markets, negatively impacting global growth prospects. As the COVID-19 global pandemic illustrated, such events may affect certain geographic regions, countries, sectors and industries more significantly than others. Advancements in technology may also adversely impact markets and the overall performance of the Fund. For instance, the economy may be significantly impacted by the advanced development and increased regulation of artificial intelligence. Additionally, cyber security breaches of both government and non-government entities could have negative impacts on infrastructure and the ability of such entities, including the Fund, to operate properly. These events, and any other future events, may adversely affect the prices and liquidity of the Fund’s portfolio investments and could result in disruptions in the trading markets.

Roundhill Innovation-100 WeeklyPay™ ETF | CYBERSECURITY RISK

Risk [Text Block]

CYBERSECURITY RISK. Failures or breaches of the electronic systems of the Fund, the Fund’s adviser, sub-adviser, distributor and other service providers, market makers, Authorized Participants or the issuers of securities in which the Fund invests have the ability to cause disruptions, negatively impact the Fund’s business operations and/or potentially result in financial losses to the Fund and its shareholders. While the Fund has established business continuity plans and risk management systems seeking to address system breaches or failures, there are inherent limitations in such plans and systems. Furthermore, the Fund cannot control the cybersecurity plans and systems of the Fund’s other service providers, market makers, Authorized Participants or issuers of securities in which the Fund invests.

Roundhill Innovation-100 WeeklyPay™ ETF | DEBT SECURITIES RISK  
Prospectus [Line Items]  
Risk [Text Block]

DEBT SECURITIES RISK. Investments in debt securities subject the holder to the credit risk of the issuer. Credit risk refers to the possibility that the issuer or other obligor of a security will not be able or willing to make payments of interest and principal when due. Generally, the value of debt securities will change inversely with changes in interest rates. To the extent that interest rates rise, certain underlying obligations may be paid off substantially slower than originally anticipated and the value of those securities may fall sharply. During periods of falling interest rates, the income received by the Fund may decline. If the principal on a debt security is prepaid before expected, the prepayments of principal may have to be reinvested in obligations paying interest at lower rates. Debt securities generally do not trade on a securities exchange making them generally less liquid and more difficult to value than common stock.

Roundhill Innovation-100 WeeklyPay™ ETF | DERIVATIVES RISK  
Prospectus [Line Items]  
Risk [Text Block]

DERIVATIVES RISK. The use of derivative instruments involves risks different from, or possibly greater than, the risks associated with investing directly in securities and other traditional investments. These risks include: (i) the risk that the counterparty to a derivative transaction may not fulfill its contractual obligations; (ii) risk of mispricing or improper valuation; and (iii) the risk that changes in the value of the derivative may not correlate perfectly with the underlying asset. Derivative prices are highly volatile and may fluctuate substantially during a short period of time. Such prices are influenced by numerous factors that affect the markets, including, but not limited to: changing supply and demand relationships; government programs and policies; national and international political and economic events, changes in interest rates, inflation and deflation and changes in supply and demand relationships. Trading derivative instruments involves risks different from, or possibly greater than, the risks associated with investing directly in securities. Derivative contracts ordinarily have leverage inherent in their terms. The use of leverage may cause the Fund to liquidate portfolio positions when it would not be advantageous to do so in order to satisfy its obligations or to meet regulatory or contractual requirements for derivatives. The use of derivatives can magnify potential for gain or loss and, therefore, amplify the effects of market volatility on share price.

Roundhill Innovation-100 WeeklyPay™ ETF | DISTRIBUTION TAX RISK  
Prospectus [Line Items]  
Risk [Text Block]

DISTRIBUTION TAX RISK. The Fund currently expects to make distributions on a weekly basis. Such frequent distributions may expose investors to increased tax liabilities. However, these distributions may exceed the Fund’s income and gains for the Fund’s taxable year. Distributions in excess of the Fund’s current and accumulated earnings and profits will be treated as a return of capital. A return of capital distribution generally will not be taxable but will reduce the shareholder’s cost basis and will result in a higher capital gain or lower capital loss when those Fund Shares on which the distribution was received are sold. Once a Fund shareholder’s cost basis is reduced to zero, further distributions will be treated as capital gain if the Fund shareholder holds Fund Shares as capital assets. Additionally, any capital returned through distributions will be distributed after payment of Fund fees and expenses. Because a portion of the Fund’s distributions may consist of return of capital, the Fund may not be an appropriate investment for investors who do not want their principal investment in the Fund to decrease over time or who do not wish to receive return of capital in a given period. In the event that a shareholder purchases Fund Shares shortly before a distribution by the Fund, the entire distribution may be taxable to the shareholder even though a portion of the distribution effectively represents a return of the purchase price.

Roundhill Innovation-100 WeeklyPay™ ETF | ETF RISK  
Prospectus [Line Items]  
Risk [Text Block]

ETF RISK. The Fund may invest in ETFs. The value of an ETF held by the Fund will fluctuate over time based on fluctuations in the values of the assets held by the ETF, which may be affected by changes in general economic conditions, expectations for future growth and profits, interest rates and the supply and demand for those assets. When the Fund invests in an ETF, it will bear a proportionate share of the ETF’s expenses. Brokerage, tax and other expenses may negatively impact the performance of the ETF and, in turn, the value of the Fund Shares. An ETF that tracks an index may not exactly match the performance of the index due to cash drag, differences between the portfolio of the ETF and the components of the index, expenses and other factors.

Roundhill Innovation-100 WeeklyPay™ ETF | INFLATION RISK  
Prospectus [Line Items]  
Risk [Text Block]

INFLATION RISK. Inflation risk is the risk that the value of assets or income from investments will be less in the future as inflation decreases the value of money. As inflation increases, the present value of the Fund’s assets and distributions may decline. This risk is more prevalent with respect to fixed income securities held by the Fund.

Roundhill Innovation-100 WeeklyPay™ ETF | Interest Rate Risk [Member]  
Prospectus [Line Items]  
Risk [Text Block]

INTEREST RATE RISK. Interest rate risk is the risk that the value of the debt securities in the Fund’s portfolio will decline because of rising market interest rates. Interest rate risk is generally lower for shorter term debt securities and higher for longer-term debt securities. Duration is a reasonably accurate measure of a debt security’s price sensitivity to changes in interest rates and a common measure of interest rate risk. Duration measures a debt security’s expected life on a present value basis, taking into account the debt security’s yield, interest payments and final maturity. In general, duration represents the expected percentage change in the value of a security for an immediate 1% change in interest rates. For example, the price of a debt security with a three-year duration would be expected to drop by approximately 3% in response to a 1% increase in interest rates. Therefore, prices of debt securities with shorter durations tend to be less sensitive to interest rate changes than debt securities with longer durations. As the value of a debt security changes over time, so will its duration.

Roundhill Innovation-100 WeeklyPay™ ETF | LEGISLATION AND LITIGATION RISK  
Prospectus [Line Items]  
Risk [Text Block]

LEGISLATION AND LITIGATION RISK. Legislation or litigation that affects the value of assets or securities held by the Fund may reduce the value of the Fund. From time to time, various legislative initiatives are proposed that may have a negative impact on certain assets or securities in which the Fund invests. In addition, litigation regarding any of the assets or securities owned by the Fund may negatively impact the value of the Shares. Such legislation or litigation may cause the Fund to lose value or may result in higher portfolio turnover if the Adviser determines to sell such a holding.

Roundhill Innovation-100 WeeklyPay™ ETF | LEVERAGE RISK  
Prospectus [Line Items]  
Risk [Text Block]

LEVERAGE RISK. The Fund obtains investment exposure in excess of its net assets by utilizing leverage and may lose more money in market conditions that are adverse to its investment objectives than a fund that does not utilize leverage. An investment in the Fund is exposed to the risk that a decline in the weekly performance of shares of the Innovation-100 ETF will be magnified. This means that an investment in the Fund will be reduced by an amount equal to 1.2% for every 1% weekly decline in the market value of the Innovation-100 ETF shares, not including the costs of financing leverage and other operating expenses, which would further reduce its value. The Fund could theoretically lose an amount greater than its net assets in the event the market value of the Innovation-100 ETF shares decline more than 83.33% over a calendar week. Leverage will also have the effect of magnifying any differences in the Fund’s correlation with the Innovation-100 ETF shares.

Roundhill Innovation-100 WeeklyPay™ ETF | MONEY MARKET INSTRUMENTS RISK  
Prospectus [Line Items]  
Risk [Text Block]

MONEY MARKET INSTRUMENTS RISK. The value of money market instruments may be affected by changing interest rates and by changes in the credit ratings of the investments. If a significant amount of the Fund’s assets are invested in money market instruments, it will be more difficult for the Fund to achieve its investment objectives. An investment in a money market fund is not insured or guaranteed by the FDIC or any other government agency. It is possible to lose money by investing in a money market fund.

Roundhill Innovation-100 WeeklyPay™ ETF | OPERATIONAL RISK  
Prospectus [Line Items]  
Risk [Text Block]

OPERATIONAL RISK. The Fund is subject to risks arising from various operational factors, including, but not limited to, human error, processing and communication errors, errors of the Fund’s service providers, counterparties or other third-parties, failed or inadequate processes and technology or systems failures. The Fund relies on third-parties for a range of services, including custody. Any delay or failure relating to engaging or maintaining such service providers may affect the Fund’s ability to meet its investment objectives. Although the Fund and the Adviser seek to reduce these operational risks through controls and procedures, there is no way to completely protect against such risks.

Roundhill Innovation-100 WeeklyPay™ ETF | SPECIAL TAX RISK  
Prospectus [Line Items]  
Risk [Text Block]

SPECIAL TAX RISK. The Fund intends to qualify annually and to elect to be treated as a regulated investment company under the Internal Revenue Code of 1986, as amended (the “Code”). To qualify for the favorable U.S. federal income tax treatment generally accorded to regulated investment companies, the Fund must, among other things, (i) derive in each taxable year at least 90% of its gross income from dividends, interest, payments with respect to securities loans and gains from the sale or other disposition of stock, securities or foreign currencies or other income derived with respect to its business of investing in such stock, securities or currencies, or net income derived from interests in certain publicly traded partnerships; (ii) diversify its holdings so that, at the end of each quarter of the taxable year, (a) at least 50% of the market value of the Fund’s assets is represented by cash and cash items (including receivables), U.S. government securities, the securities of other regulated investment companies and other securities, with such other securities of any one issuer generally limited for the purposes of this calculation to an amount not greater than 5% of the value of the Fund’s total assets and not greater than 10% of the outstanding voting securities of such issuer, and (b) not more than 25% of the value of its total assets is invested in the securities (other than U.S. government securities or the securities of other regulated investment companies) of any one issuer, or two or more issuers which the Fund controls which are engaged in the same, similar or related trades or businesses, or the securities of one or more of certain publicly traded partnerships; and (iii) distribute at least 90% of its investment company taxable income (which includes, among other items, dividends, interest and net short-term capital gains in excess of net long-term capital losses) and at least 90% of its net tax-exempt interest income each taxable year. There are certain exceptions for failure to qualify if the failure is for reasonable cause or is de minimis, and certain corrective action is taken and certain tax payments are made by the Fund.

 

The authority with regard to swaps entered into by regulated investment companies is unclear both as to the qualification under the income test and the identification of the issuer under the diversification test. The Fund intends to take the position that because the swaps held by the Fund reference securities that the income on the swaps are “other income” from the Fund’s business of investing in stocks and securities. In addition, the Fund intends to manage its investments in the swaps so that neither the exposure to issuer of the referenced security nor the exposure to any one counterparty of the swaps will exceed 25% of the gross value of the Fund’s portfolio at the end of any quarter.

 

If the Fund were to fail to meet the qualifying income test or asset diversification test and fail to qualify as a RIC, it would be taxed in the same manner as an ordinary corporation, and distributions to its shareholders would not be deductible by the Fund in computing its taxable income, which would adversely affect the Fund’s performance.

Roundhill Innovation-100 WeeklyPay™ ETF | STRUCTURAL ETF RISKS  
Prospectus [Line Items]  
Risk [Text Block]

STRUCTURAL ETF RISKS. The Fund is an ETF. Accordingly, it is subject to certain risks associated with its unique structure.

 

Market Participants Risk. Only an Authorized Participant may engage in creation or redemption transactions directly with the Fund, and none of those Authorized Participants is obligated to engage in creation and/or redemption transactions. The Fund has a limited number of institutions that may act as Authorized Participants on an agency basis (i.e., on behalf of other market participants). To the extent that Authorized Participants exit the business or are unable to proceed with creation or redemption orders with respect to the Fund and no other Authorized Participant is able to step forward to create or redeem, Fund Shares may be more likely to trade at a premium or discount to NAV and possibly face trading halts or delisting. The Fund may also rely on a small number of third-party market makers to provide a market for the purchase and sale of Fund Shares but such market makers are under no obligation to do so. Decisions by Authorized Participants or market makers to reduce their role or step away from these activities in times of market stress could inhibit the effectiveness of the arbitrage process in maintaining the relationship between the underlying values of the Fund’s portfolio securities and the Fund’s market price. Any trading halt or other problem relating to the trading activity of these market makers or any issues disrupting the Authorized Participants’ ability to proceed with creation and/or redemption orders could result in a dramatic change in the spread between the Fund’s net asset value and the price at which Fund Shares are trading on the Exchange, which could result in a decrease in value of Fund Shares. This reduced effectiveness could result in Fund Shares trading at a premium or discount to net asset value and also in greater than normal intraday bid-ask spreads Fund Shares.

 

Cash Transactions Risk. The Fund currently expects to effect a significant portion of its creations and redemptions for cash, rather than in-kind securities. Paying redemption proceeds in cash rather than through in-kind delivery of portfolio securities may require the Fund to dispose of or sell portfolio securities or other assets at an inopportune time to obtain the cash needed to meet redemption orders. This may cause the Fund to sell a security and recognize a capital gain or loss that might not have been incurred if it had made a redemption in-kind. As a result, the Fund may pay out higher or lower annual capital gains distributions than ETFs that redeem in-kind. The use of cash creations and redemptions may also cause the Fund’s Shares to trade in the market at greater bid-ask spreads or greater premiums or discounts to the Fund’s NAV. Furthermore, the Fund may not be able to execute cash transactions for creation and redemption purposes at the same price used to determine the Fund’s NAV. To the extent that the maximum additional charge for creation or redemption transactions is insufficient to cover the execution shortfall, the Fund’s performance could be negatively impacted.

 

Costs of Buying and Selling Fund Shares. Due to the costs of buying or selling Fund Shares, including brokerage commissions imposed by brokers and bid/ask spreads, frequent trading of Fund Shares may significantly reduce investment results and an investment in Fund Shares may not be advisable for investors who anticipate regularly making small investments.

 

Premium/Discount Risk. As with all ETFs, Fund Shares may be bought and sold in the secondary market at market prices. The trading prices of Fund Shares in the secondary market may differ from the Fund’s daily net asset value per share and there may be times when the market price of the shares is more than the net asset value per share (premium) or less than the net asset value per share (discount). If a shareholder purchases Fund Shares at a time when the market price is at a premium to the net asset value or sells Fund Shares at a time when the market price is at a discount to the net asset value, the shareholder may pay more for, or receive less than, the underlying value of the Fund Shares, respectively. This risk is heightened in times of market volatility or periods of steep market declines.

 

Trading Risks. Although Fund Shares are listed for trading on the Exchange and may be traded on U.S. exchanges other than the Exchange, there can be no assurance that Fund Shares will trade with any volume, or at all, on any stock exchange. In stressed market conditions, the liquidity of Fund Shares may begin to mirror the liquidity of the Fund’s underlying portfolio holdings, which can be significantly less liquid than Fund Shares. Trading in Fund Shares on the Exchange may be halted due to market conditions or for reasons that, in the view of the Exchange, make trading in Fund Shares inadvisable. In addition, trading in Fund Shares on the Exchange is subject to trading halts caused by extraordinary market volatility pursuant to the Exchange’s “circuit breaker” rules. There can be no assurance that the requirements of the Exchange necessary to maintain the listing of the Fund will continue to be met or will remain unchanged.

Roundhill Innovation-100 WeeklyPay™ ETF | U.S. GOVERNMENT SECURITIES RISK  
Prospectus [Line Items]  
Risk [Text Block]

U.S. GOVERNMENT SECURITIES RISK. U.S. government securities are subject to interest rate risk but generally do not involve the credit risks associated with investments in other types of debt securities. As a result, the yields available from U.S. government securities are generally lower than the yields available from other debt securities. U.S. government securities are guaranteed only as to the timely payment of interest and the payment of principal when held to maturity.

Roundhill Innovation-100 WeeklyPay™ ETF | VALUATION RISK  
Prospectus [Line Items]  
Risk [Text Block]

VALUATION RISK. The Fund may hold securities or other assets that may be valued on the basis of factors other than market quotations. This may occur because the asset or security does not trade on a centralized exchange, or in times of market turmoil or reduced liquidity. There are multiple methods that can be used to value a portfolio holding when market quotations are not readily available. The value established for any portfolio holding at a point in time might differ from what would be produced using a different methodology or if it had been priced using market quotations. Portfolio holdings that are valued using techniques other than market quotations, including “fair valued” assets or securities, may be subject to greater fluctuation in their valuations from one day to the next than if market quotations were used. In addition, there is no assurance that the Fund could sell or close out a portfolio position for the value established for it at any time, and it is possible that the Fund would incur a loss because a portfolio position is sold or closed out at a discount to the valuation established by the Fund at that time. The Fund’s ability to value investments may be impacted by technological issues or errors by pricing services or other third-party service providers.

Roundhill Innovation-100 WeeklyPay™ ETF | EQUITY SECURITIES RISK  
Prospectus [Line Items]  
Risk [Text Block]

EQUITY SECURITIES RISK. Equity securities are subject to changes in value, and their values may be more volatile than those of other asset classes. Equity securities prices fluctuate for several reasons, including changes in investors’ perceptions of the financial condition of an issuer or the general condition of the relevant equity market, such as market volatility, or when political or economic events affecting an issuer occur. Common stock prices may be particularly sensitive to rising interest rates, as the cost of capital rises and borrowing costs increase. Common stocks generally subject their holders to more risks than preferred stocks and debt securities because common stockholders’ claims are subordinated to those of holders of preferred stocks and debt securities upon the bankruptcy of the issuer.

Roundhill Innovation-100 WeeklyPay™ ETF | SWAP AGREEMENTS RISK  
Prospectus [Line Items]  
Risk [Text Block]

SWAP AGREEMENTS RISK. The Fund will utilize swap agreements to derive its exposure to shares of the Innovation-100 ETF. Swap agreements may involve greater risks than direct investment in securities as they may be leveraged and are subject to credit risk, counterparty risk and valuation risk. A swap agreement could result in losses if the underlying reference or asset does not perform as anticipated. In addition, many swaps trade over-the-counter and may be considered illiquid. It may not be possible for the Fund to liquidate a swap position at an advantageous time or price, which may result in significant losses.

Roundhill Innovation-100 WeeklyPay™ ETF | NEW FUND RISK  
Prospectus [Line Items]

NEW FUND RISK. The Fund is a recently organized investment company with a limited operating history. As a result, prospective investors have a limited track record or history on which to base their investment decision.

Risk [Text Block]

REGULATED INVESTMENT COMPANY TAX RISKS. The Fund intends to qualify annually and to elect to be treated as a regulated investment company under the Internal Revenue Code of 1986, as amended (the “Code”). To qualify for the favorable U.S. federal income tax treatment generally accorded to regulated investment companies, the Fund must, among other things, (i) derive in each taxable year at least 90% of its gross income from dividends, interest, payments with respect to securities loans and gains from the sale or other disposition of stock, securities or foreign currencies or other income derived with respect to its business of investing in such stock, securities or currencies, or net income derived from interests in certain publicly traded partnerships; (ii) diversify its holdings so that, at the end of each quarter of the taxable year, (a) at least 50% of the market value of the Fund’s assets is represented by cash and cash items (including receivables), U.S. government securities, the securities of other regulated investment companies and other securities, with such other securities of any one issuer generally limited for the purposes of this calculation to an amount not greater than 5% of the value of the Fund’s total assets and not greater than 10% of the outstanding voting securities of such issuer, and (b) not more than 25% of the value of its total assets is invested in the securities (other than U.S. government securities or the securities of other regulated investment companies) of any one issuer, or two or more issuers which the Fund controls which are engaged in the same, similar or related trades or businesses, or the securities of one or more of certain publicly traded partnerships; and (iii) distribute at least 90% of its investment company taxable income (which includes, among other items, dividends, interest and net short-term capital gains in excess of net long-term capital losses) and at least 90% of its net tax-exempt interest income each taxable year. There are certain exceptions for failure to qualify if the failure is for reasonable cause or is de minimis, and certain corrective action is taken and certain tax payments are made by the Fund.

 

If the Fund were to fail to meet the qualifying income test or asset diversification test and fail to qualify as a RIC, it would be taxed in the same manner as an ordinary corporation, and distributions to its shareholders would not be deductible by the Fund in computing its taxable income, which would adversely affect the Fund’s performance.

Roundhill Innovation-100 WeeklyPay™ ETF | LARGE SHAREHOLDER RISK  
Prospectus [Line Items]  
Risk [Text Block]

LARGE SHAREHOLDER RISK. Certain shareholders, including affiliated funds advised by the Adviser, may from time to time own a significant portion of the Fund’s shares. In addition, a third-party investor, the Adviser or an affiliate of the Adviser (“Affiliate”), an authorized participant, a market maker, or another entity may invest in the Fund and hold its investment for a limited period solely to facilitate the commencement of the Fund or to help the Fund achieve a specified size or scale. There can be no assurance that any large shareholder will not redeem its investment, that the size of the Fund will be maintained at such levels, or that the Fund will continue to meet applicable listing requirements. Redemptions by large shareholders could have a significant negative impact on the Fund. In addition, transactions by large shareholders may account for a large percentage of the trading volume on the Fund’s listing exchange and may, therefore, have a material upward or downward effect on the market price of the shares.

 

To the extent that a significant percentage of the Fund’s shares are owned or controlled by a small number of account shareholders (or a single account shareholder), including funds or accounts over which the Adviser or an Affiliate has investment discretion, the Fund is subject to the risk that those shareholders may purchase or redeem Fund shares in significant amounts rapidly or unexpectedly, including as a result of an asset allocation decision made by the Adviser or an Affiliate. This may adversely affect the Fund’s performance if the Adviser is forced to sell portfolio securities or invest cash when it would not otherwise choose to do so. Redemptions of a large number of shares may affect the liquidity of the Fund’s portfolio, increase the Fund’s transaction costs, and accelerate the realization of taxable income and/or gains. In addition, a large redemption could result in the Fund’s current expenses being allocated over a smaller asset base, leading to an increase in the Fund’s gross expense ratio. Large purchases of the Fund’s shares may also adversely affect the Fund’s performance to the extent that the Fund is delayed in investing new cash or otherwise maintains a larger cash position than it ordinarily would, particularly if the Fund accepts cash for an order for the purchase of creation units of the Fund’s shares.

Roundhill Innovation-100 WeeklyPay™ ETF | INNOVATION-100 ETF INVESTING RISKS

INNOVATION-100 ETF INVESTING RISKS. The Fund will have significant exposure to the Innovation-100 ETF through its investments in shares of the Innovation-100 ETF and swap agreements that utilize the Innovation-100 ETF as the reference asset. Accordingly, the Fund will subject to the risks of the Innovation-100 ETF, set forth below. In addition to these risks, the Innovation-100 ETF is also subject to the following risks to which the Fund is also subject, which are described within the section entitled “Principal Risks”: Market Risk, Asset Class Risk, Concentration Risk, Current Market Conditions Risk, Cybersecurity Risk, Equity Securities Risk, Operational Risk and Structural ETF Risk.

 

INDEX-RELATED RISK. The Innovation-100 ETF Index Provider may rely on various sources of information to assess the criteria of components of the Innovation-100 ETF Index, including information that may be based on assumptions and estimates. Neither the Innovation-100 ETF nor its investment adviser offer assurances that the Innovation-100 ETF Index Provider’s methodology or sources of information will provide an accurate assessment of included components or will result in the Innovation-100 ETF meeting its investment objective. Errors in index data, index computations or the construction of the Innovation-100 ETF Index in accordance with its methodology may occur, and the Innovation-100 ETF Index Provider may not identify or correct them promptly or at all, which may have an adverse impact on the Innovation-100 ETF and its shareholders. Unusual market conditions or other unforeseen circumstances (such as natural disasters, political unrest or war) may impact the Innovation-100 ETF Index Provider or a third-party data provider and could cause the Innovation-100 ETF Index Provider to postpone a scheduled rebalance. This could cause the Innovation-100 ETF Index to vary from its normal or expected composition.

 

INDIRECT INVESTMENT RISK. The Innovation-100 ETF is not affiliated with the Trust, the Fund, the Adviser, the Sub-Adviser or any affiliates thereof and is not involved with this offering in any way, and has no obligation to consider the Fund in taking any actions that might affect the value of the Fund. The Trust, the Fund, the Adviser, the Sub-Adviser or any affiliate are not responsible for the performance of the Innovation-100 ETF and make no representation as to the performance of the Innovation-100 ETF. Investing in the Fund is not equivalent to investing in the Innovation-100 ETF Fund shareholders will not have voting rights or rights to receive dividends or other distributions or any other rights with respect to the Innovation-100 ETF.

 

INFORMATION TECHNOLOGY COMPANIES RISK. Information technology companies face intense competition, both domestically and internationally, which may have an adverse effect on profit margins. Like other technology companies, information technology companies may have limited product lines, markets, financial resources or personnel. The products of information technology companies may face obsolescence due to rapid technological developments, frequent new product introduction, unpredictable changes in growth rates and competition for the services of qualified personnel. Companies in the information technology sector are heavily dependent on patent and intellectual property rights. The loss or impairment of these rights may adversely affect the profitability of these companies. Information technology companies are facing increased government and regulatory scrutiny and may be subject to adverse government or regulatory action.

 

LARGE CAPITALIZATION COMPANIES RISK. Large capitalization companies may be less able than smaller capitalization companies to adapt to changing market conditions. Large capitalization companies may be more mature and subject to more limited growth potential compared with smaller capitalization companies. During different market cycles, the performance of large capitalization companies has trailed the overall performance of the broader securities markets.

 

UNITED STATES RISK. Certain changes in the U.S. economy, such as when the U.S. economy weakens or when its financial markets decline, may have an adverse effect on the securities to which the Fund has exposure.

NON-DIVERSIFICATION RISK. As a “non-diversified” fund, the Fund may hold a smaller number of portfolio securities than many other funds. To the extent the Fund invests in a relatively small number of issuers, a decline in the market value of a particular security held by the Fund may affect its value more than if it invested in a larger number of issuers. The value of the Fund Shares may be more volatile than the values of shares of more diversified funds.

Roundhill Semiconductor WeeklyPay™ ETF | MARKET RISK  
Prospectus [Line Items]  
Risk [Text Block]

MARKET RISK. Market risk is the risk that a particular investment, or Fund Shares in general, may fall in value. Securities are subject to market fluctuations caused by real or perceived adverse economic, political, and regulatory factors or market developments, changes in interest rates, disruptions to trade, impositions of tariffs and perceived trends in securities prices. Fund Shares could decline in value or underperform other investments. In addition, local, regional or global events such as war, acts of terrorism, market manipulation, government defaults, government shutdowns, regulatory actions, political changes, diplomatic developments, the imposition of sanctions and other similar measures, spread of infectious diseases or other public health issues, recessions, natural disasters, or other events could have a significant negative impact on the Fund and its investments. Any of such circumstances could have a materially negative impact on the value of Fund Shares, the liquidity of an investment, and may result in increased market volatility. During any such events, Fund Shares may trade at increased premiums or discounts to their net asset value, the bid/ask spread on Fund Shares may widen and the returns on investment may fluctuate.

Roundhill Semiconductor WeeklyPay™ ETF | LIQUIDITY RISK  
Prospectus [Line Items]  
Risk [Text Block]

LIQUIDITY RISK. The market for swap agreements that reference the Semiconductor ETF shares may be subject to periods of illiquidity. During such times it may be difficult or impossible to buy or sell a position at the desired price. Market disruptions or volatility can also make it difficult to find a counterparty willing to transact at a reasonable price and sufficient size. Illiquid markets may cause losses, which could be significant. The large size of the positions which the Fund may acquire increases the risk of illiquidity, may make its positions more difficult to liquidate, and may increase the losses incurred while trying to do so. Such large positions also may impact the price of swap agreements on the Semiconductor ETF shares.

Roundhill Semiconductor WeeklyPay™ ETF | ACTIVE MANAGEMENT RISK

ACTIVE MANAGEMENT RISK. The Fund is actively-managed and its performance reflects investment decisions that the Adviser and/or Sub-Adviser makes for the Fund. Such judgments about the Fund’s investments may prove to be incorrect. If the investments selected and the strategies employed by the Fund fail to produce the intended results, the Fund could underperform as compared to other funds with similar investment objectives and/or strategies, or could have negative returns.

ACTIVE MARKET RISK. Although Fund Shares are listed for trading on the Exchange, there can be no assurance that an active trading market for Fund Shares will develop or be maintained. Fund Shares trade on the Exchange at market prices that may be below, at or above the Fund’s net asset value. Securities, including Fund Shares, are subject to market fluctuations and liquidity constraints that may be caused by such factors as economic, political, or regulatory developments, changes in interest rates, and/or perceived trends in securities prices. Fund Shares could decline in value or underperform other investments.

The Fund is susceptible to an increased risk of loss, including losses due to adverse events that affect the Fund’s investments more than the market as a whole, to the extent that the Fund’s investments are concentrated in investments that provide exposure to the Semiconductor ETF and the industry or group of industries to which it is concentrated.

Roundhill Semiconductor WeeklyPay™ ETF | COUNTERPARTY RISK

Risk [Text Block]

COUNTERPARTY RISK. Fund transactions involving a counterparty are subject to the risk that the counterparty will not fulfill its obligation to the Fund. Counterparty risk may arise because of the counterparty’s financial condition (i.e., financial difficulties, bankruptcy, or insolvency), market activities and developments, or other reasons, whether foreseen or not. A counterparty’s inability to fulfill its obligation may result in significant financial loss to the Fund. The Fund may be unable to recover its investment from the counterparty or may obtain a limited recovery, and/or recovery may be delayed.

CREDIT RISK. An issuer or other obligated party of a debt security may be unable or unwilling to make dividend, interest and/or principal payments when due. In addition, the value of a debt security may decline because of concerns about the issuer’s ability or unwillingness to make such payments.

Roundhill Semiconductor WeeklyPay™ ETF | CURRENT MARKET CONDITIONS RISK  
Prospectus [Line Items]  
Risk [Text Block]

CURRENT MARKET CONDITIONS RISK. Current market conditions risk is the risk that a particular investment, or Fund Shares in general, may fall in value due to current market conditions. As a means to fight inflation, which remains at elevated levels, the Federal Reserve and certain foreign central banks have raised interest rates; however, the Federal Reserve has recently lowered interest rates and may continue to do so. U.S. regulators have proposed several changes to market and issuer regulations which would directly impact the Fund, and any regulatory changes could adversely impact the Fund’s ability to achieve its investment strategies or make certain investments. Recent and potential future bank failures could result in disruption to the broader banking industry or markets generally and reduce confidence in financial institutions and the economy as a whole, which may also heighten market volatility and reduce liquidity. Additionally, challenges in commercial real estate markets, including rising interest rates, declining valuations and increasing vacancies, could have a broader impact on financial markets. The ongoing adversarial political climate in the United States, as well as political and diplomatic events both domestic and abroad, have and may continue to have an adverse impact the U.S. regulatory landscape, markets and investor behavior, which could have a negative impact on the Fund’s investments and operations. The change in administration resulting from the 2024 United States national elections could result in significant impacts to international trade relations, tax and immigration policies, and other aspects of the national and international political and financial landscape, which could affect, among other things, inflation and the securities markets generally. Other unexpected political, regulatory and diplomatic events within the U.S. and abroad may affect investor and consumer confidence and may adversely impact financial markets and the broader economy. For example, ongoing armed conflicts between Russia and Ukraine in Europe and among Israel, Iran, Hamas and other militant groups in the Middle East, have caused and could continue to cause significant market disruptions and volatility within the markets in Russia, Europe, the Middle East and the United States. The hostilities and sanctions resulting from those hostilities have and could continue to have a significant impact on certain Fund investments as well as Fund performance and liquidity. The economies of the United States and its trading partners, as well as the financial markets generally, may be adversely impacted by trade disputes, including the imposition of tariffs, and other matters. For example, the United States has imposed trade barriers and restrictions on China. In addition, the Chinese government is engaged in a longstanding dispute with Taiwan, continually threatening an invasion. If the political climate between the United States and China does not improve or continues to deteriorate, if China were to attempt invading Taiwan, or if other geopolitical conflicts develop or worsen, economies, markets and individual securities may be adversely affected, and the value of the Fund’s assets may go down. A public health crisis and the ensuing policies enacted by governments and central banks may cause significant volatility and uncertainty in global financial markets, negatively impacting global growth prospects. As the COVID-19 global pandemic illustrated, such events may affect certain geographic regions, countries, sectors and industries more significantly than others. Advancements in technology may also adversely impact markets and the overall performance of the Fund. For instance, the economy may be significantly impacted by the advanced development and increased regulation of artificial intelligence. Additionally, cyber security breaches of both government and non-government entities could have negative impacts on infrastructure and the ability of such entities, including the Fund, to operate properly. These events, and any other future events, may adversely affect the prices and liquidity of the Fund’s portfolio investments and could result in disruptions in the trading markets.

Roundhill Semiconductor WeeklyPay™ ETF | CYBERSECURITY RISK  
Prospectus [Line Items]  
Risk [Text Block]

CYBERSECURITY RISK. Failures or breaches of the electronic systems of the Fund, the Fund’s adviser, sub-adviser, distributor and other service providers, market makers, Authorized Participants or the issuers of securities in which the Fund invests have the ability to cause disruptions, negatively impact the Fund’s business operations and/or potentially result in financial losses to the Fund and its shareholders. While the Fund has established business continuity plans and risk management systems seeking to address system breaches or failures, there are inherent limitations in such plans and systems. Furthermore, the Fund cannot control the cybersecurity plans and systems of the Fund’s other service providers, market makers, Authorized Participants or issuers of securities in which the Fund invests.

Roundhill Semiconductor WeeklyPay™ ETF | DEBT SECURITIES RISK  
Prospectus [Line Items]  
Risk [Text Block]

DEBT SECURITIES RISK. Investments in debt securities subject the holder to the credit risk of the issuer. Credit risk refers to the possibility that the issuer or other obligor of a security will not be able or willing to make payments of interest and principal when due. Generally, the value of debt securities will change inversely with changes in interest rates. To the extent that interest rates rise, certain underlying obligations may be paid off substantially slower than originally anticipated and the value of those securities may fall sharply. During periods of falling interest rates, the income received by the Fund may decline. If the principal on a debt security is prepaid before expected, the prepayments of principal may have to be reinvested in obligations paying interest at lower rates. Debt securities generally do not trade on a securities exchange making them generally less liquid and more difficult to value than common stock.

Roundhill Semiconductor WeeklyPay™ ETF | DERIVATIVES RISK  
Prospectus [Line Items]  
Risk [Text Block]

DERIVATIVES RISK. The use of derivative instruments involves risks different from, or possibly greater than, the risks associated with investing directly in securities and other traditional investments. These risks include: (i) the risk that the counterparty to a derivative transaction may not fulfill its contractual obligations; (ii) risk of mispricing or improper valuation; and (iii) the risk that changes in the value of the derivative may not correlate perfectly with the underlying asset. Derivative prices are highly volatile and may fluctuate substantially during a short period of time. Such prices are influenced by numerous factors that affect the markets, including, but not limited to: changing supply and demand relationships; government programs and policies; national and international political and economic events, changes in interest rates, inflation and deflation and changes in supply and demand relationships. Trading derivative instruments involves risks different from, or possibly greater than, the risks associated with investing directly in securities. Derivative contracts ordinarily have leverage inherent in their terms. The use of leverage may cause the Fund to liquidate portfolio positions when it would not be advantageous to do so in order to satisfy its obligations or to meet regulatory or contractual requirements for derivatives. The use of derivatives can magnify potential for gain or loss and, therefore, amplify the effects of market volatility on share price.

Roundhill Semiconductor WeeklyPay™ ETF | DISTRIBUTION TAX RISK  
Prospectus [Line Items]  
Risk [Text Block]

DISTRIBUTION TAX RISK. The Fund currently expects to make distributions on a weekly basis. Such frequent distributions may expose investors to increased tax liabilities. However, these distributions may exceed the Fund’s income and gains for the Fund’s taxable year. Distributions in excess of the Fund’s current and accumulated earnings and profits will be treated as a return of capital. A return of capital distribution generally will not be taxable but will reduce the shareholder’s cost basis and will result in a higher capital gain or lower capital loss when those Fund Shares on which the distribution was received are sold. Once a Fund shareholder’s cost basis is reduced to zero, further distributions will be treated as capital gain if the Fund shareholder holds Fund Shares as capital assets. Additionally, any capital returned through distributions will be distributed after payment of Fund fees and expenses. Because a portion of the Fund’s distributions may consist of return of capital, the Fund may not be an appropriate investment for investors who do not want their principal investment in the Fund to decrease over time or who do not wish to receive return of capital in a given period. In the event that a shareholder purchases Fund Shares shortly before a distribution by the Fund, the entire distribution may be taxable to the shareholder even though a portion of the distribution effectively represents a return of the purchase price.

Roundhill Semiconductor WeeklyPay™ ETF | ETF RISK  
Prospectus [Line Items]  
Risk [Text Block]

ETF RISK. The Fund may invest in ETFs. The value of an ETF held by the Fund will fluctuate over time based on fluctuations in the values of the assets held by the ETF, which may be affected by changes in general economic conditions, expectations for future growth and profits, interest rates and the supply and demand for those assets. When the Fund invests in an ETF, it will bear a proportionate share of the ETF’s expenses. Brokerage, tax and other expenses may negatively impact the performance of the ETF and, in turn, the value of the Fund Shares. An ETF that tracks an index may not exactly match the performance of the index due to cash drag, differences between the portfolio of the ETF and the components of the index, expenses and other factors.

Roundhill Semiconductor WeeklyPay™ ETF | INFLATION RISK  
Prospectus [Line Items]  
Risk [Text Block]

INFLATION RISK. Inflation risk is the risk that the value of assets or income from investments will be less in the future as inflation decreases the value of money. As inflation increases, the present value of the Fund’s assets and distributions may decline. This risk is more prevalent with respect to fixed income securities held by the Fund.

Roundhill Semiconductor WeeklyPay™ ETF | Interest Rate Risk [Member]  
Prospectus [Line Items]  
Risk [Text Block]

INTEREST RATE RISK. Interest rate risk is the risk that the value of the debt securities in the Fund’s portfolio will decline because of rising market interest rates. Interest rate risk is generally lower for shorter term debt securities and higher for longer-term debt securities. Duration is a reasonably accurate measure of a debt security’s price sensitivity to changes in interest rates and a common measure of interest rate risk. Duration measures a debt security’s expected life on a present value basis, taking into account the debt security’s yield, interest payments and final maturity. In general, duration represents the expected percentage change in the value of a security for an immediate 1% change in interest rates. For example, the price of a debt security with a three-year duration would be expected to drop by approximately 3% in response to a 1% increase in interest rates. Therefore, prices of debt securities with shorter durations tend to be less sensitive to interest rate changes than debt securities with longer durations. As the value of a debt security changes over time, so will its duration.

Roundhill Semiconductor WeeklyPay™ ETF | LEGISLATION AND LITIGATION RISK  
Prospectus [Line Items]  
Risk [Text Block]

LEGISLATION AND LITIGATION RISK. Legislation or litigation that affects the value of assets or securities held by the Fund may reduce the value of the Fund. From time to time, various legislative initiatives are proposed that may have a negative impact on certain assets or securities in which the Fund invests. In addition, litigation regarding any of the assets or securities owned by the Fund may negatively impact the value of the Shares. Such legislation or litigation may cause the Fund to lose value or may result in higher portfolio turnover if the Adviser determines to sell such a holding.

Roundhill Semiconductor WeeklyPay™ ETF | LEVERAGE RISK  
Prospectus [Line Items]  
Risk [Text Block]

LEVERAGE RISK. The Fund obtains investment exposure in excess of its net assets by utilizing leverage and may lose more money in market conditions that are adverse to its investment objectives than a fund that does not utilize leverage. An investment in the Fund is exposed to the risk that a decline in the weekly performance of shares of the Semiconductor ETF will be magnified. This means that an investment in the Fund will be reduced by an amount equal to 1.2% for every 1% weekly decline in the market value of the Semiconductor ETF shares, not including the costs of financing leverage and other operating expenses, which would further reduce its value. The Fund could theoretically lose an amount greater than its net assets in the event the market value of the Semiconductor ETF shares decline more than 83.33% over a calendar week. Leverage will also have the effect of magnifying any differences in the Fund’s correlation with the Semiconductor ETF shares.

Roundhill Semiconductor WeeklyPay™ ETF | MONEY MARKET INSTRUMENTS RISK  
Prospectus [Line Items]  
Risk [Text Block]

MONEY MARKET INSTRUMENTS RISK. The value of money market instruments may be affected by changing interest rates and by changes in the credit ratings of the investments. If a significant amount of the Fund’s assets are invested in money market instruments, it will be more difficult for the Fund to achieve its investment objectives. An investment in a money market fund is not insured or guaranteed by the FDIC or any other government agency. It is possible to lose money by investing in a money market fund.

Roundhill Semiconductor WeeklyPay™ ETF | OPERATIONAL RISK  
Prospectus [Line Items]  
Risk [Text Block]

OPERATIONAL RISK. The Fund is subject to risks arising from various operational factors, including, but not limited to, human error, processing and communication errors, errors of the Fund’s service providers, counterparties or other third-parties, failed or inadequate processes and technology or systems failures. The Fund relies on third-parties for a range of services, including custody. Any delay or failure relating to engaging or maintaining such service providers may affect the Fund’s ability to meet its investment objectives. Although the Fund and the Adviser seek to reduce these operational risks through controls and procedures, there is no way to completely protect against such risks.

Roundhill Semiconductor WeeklyPay™ ETF | SPECIAL TAX RISK  
Prospectus [Line Items]  
Risk [Text Block]

SPECIAL TAX RISK. The Fund intends to qualify annually and to elect to be treated as a regulated investment company under the Internal Revenue Code of 1986, as amended (the “Code”). To qualify for the favorable U.S. federal income tax treatment generally accorded to regulated investment companies, the Fund must, among other things, (i) derive in each taxable year at least 90% of its gross income from dividends, interest, payments with respect to securities loans and gains from the sale or other disposition of stock, securities or foreign currencies or other income derived with respect to its business of investing in such stock, securities or currencies, or net income derived from interests in certain publicly traded partnerships; (ii) diversify its holdings so that, at the end of each quarter of the taxable year, (a) at least 50% of the market value of the Fund’s assets is represented by cash and cash items (including receivables), U.S. government securities, the securities of other regulated investment companies and other securities, with such other securities of any one issuer generally limited for the purposes of this calculation to an amount not greater than 5% of the value of the Fund’s total assets and not greater than 10% of the outstanding voting securities of such issuer, and (b) not more than 25% of the value of its total assets is invested in the securities (other than U.S. government securities or the securities of other regulated investment companies) of any one issuer, or two or more issuers which the Fund controls which are engaged in the same, similar or related trades or businesses, or the securities of one or more of certain publicly traded partnerships; and (iii) distribute at least 90% of its investment company taxable income (which includes, among other items, dividends, interest and net short-term capital gains in excess of net long-term capital losses) and at least 90% of its net tax-exempt interest income each taxable year. There are certain exceptions for failure to qualify if the failure is for reasonable cause or is de minimis, and certain corrective action is taken and certain tax payments are made by the Fund.

 

The authority with regard to swaps entered into by regulated investment companies is unclear both as to the qualification under the income test and the identification of the issuer under the diversification test. The Fund intends to take the position that because the swaps held by the Fund reference securities that the income on the swaps are “other income” from the Fund’s business of investing in stocks and securities. In addition, the Fund intends to manage its investments in the swaps so that neither the exposure to issuer of the referenced security nor the exposure to any one counterparty of the swaps will exceed 25% of the gross value of the Fund’s portfolio at the end of any quarter.

 

If the Fund were to fail to meet the qualifying income test or asset diversification test and fail to qualify as a RIC, it would be taxed in the same manner as an ordinary corporation, and distributions to its shareholders would not be deductible by the Fund in computing its taxable income, which would adversely affect the Fund’s performance.

Roundhill Semiconductor WeeklyPay™ ETF | STRUCTURAL ETF RISKS  
Prospectus [Line Items]  
Risk [Text Block]

STRUCTURAL ETF RISKS. The Fund is an ETF. Accordingly, it is subject to certain risks associated with its unique structure.

 

Market Participants Risk. Only an Authorized Participant may engage in creation or redemption transactions directly with the Fund, and none of those Authorized Participants is obligated to engage in creation and/or redemption transactions. The Fund has a limited number of institutions that may act as Authorized Participants on an agency basis (i.e., on behalf of other market participants). To the extent that Authorized Participants exit the business or are unable to proceed with creation or redemption orders with respect to the Fund and no other Authorized Participant is able to step forward to create or redeem, Fund Shares may be more likely to trade at a premium or discount to NAV and possibly face trading halts or delisting. The Fund may also rely on a small number of third-party market makers to provide a market for the purchase and sale of Fund Shares but such market makers are under no obligation to do so. Decisions by Authorized Participants or market makers to reduce their role or step away from these activities in times of market stress could inhibit the effectiveness of the arbitrage process in maintaining the relationship between the underlying values of the Fund’s portfolio securities and the Fund’s market price. Any trading halt or other problem relating to the trading activity of these market makers or any issues disrupting the Authorized Participants’ ability to proceed with creation and/or redemption orders could result in a dramatic change in the spread between the Fund’s net asset value and the price at which Fund Shares are trading on the Exchange, which could result in a decrease in value of Fund Shares. This reduced effectiveness could result in Fund Shares trading at a premium or discount to net asset value and also in greater than normal intraday bid-ask spreads Fund Shares.

 

Cash Transactions Risk. The Fund currently expects to effect a significant portion of its creations and redemptions for cash, rather than in-kind securities. Paying redemption proceeds in cash rather than through in-kind delivery of portfolio securities may require the Fund to dispose of or sell portfolio securities or other assets at an inopportune time to obtain the cash needed to meet redemption orders. This may cause the Fund to sell a security and recognize a capital gain or loss that might not have been incurred if it had made a redemption in-kind. As a result, the Fund may pay out higher or lower annual capital gains distributions than ETFs that redeem in-kind. The use of cash creations and redemptions may also cause the Fund’s Shares to trade in the market at greater bid-ask spreads or greater premiums or discounts to the Fund’s NAV. Furthermore, the Fund may not be able to execute cash transactions for creation and redemption purposes at the same price used to determine the Fund’s NAV. To the extent that the maximum additional charge for creation or redemption transactions is insufficient to cover the execution shortfall, the Fund’s performance could be negatively impacted.

 

Costs of Buying and Selling Fund Shares. Due to the costs of buying or selling Fund Shares, including brokerage commissions imposed by brokers and bid/ask spreads, frequent trading of Fund Shares may significantly reduce investment results and an investment in Fund Shares may not be advisable for investors who anticipate regularly making small investments.

 

Premium/Discount Risk. As with all ETFs, Fund Shares may be bought and sold in the secondary market at market prices. The trading prices of Fund Shares in the secondary market may differ from the Fund’s daily net asset value per share and there may be times when the market price of the shares is more than the net asset value per share (premium) or less than the net asset value per share (discount). If a shareholder purchases Fund Shares at a time when the market price is at a premium to the net asset value or sells Fund Shares at a time when the market price is at a discount to the net asset value, the shareholder may pay more for, or receive less than, the underlying value of the Fund Shares, respectively. This risk is heightened in times of market volatility or periods of steep market declines.

 

Trading Risks. Although Fund Shares are listed for trading on the Exchange and may be traded on U.S. exchanges other than the Exchange, there can be no assurance that Fund Shares will trade with any volume, or at all, on any stock exchange. In stressed market conditions, the liquidity of Fund Shares may begin to mirror the liquidity of the Fund’s underlying portfolio holdings, which can be significantly less liquid than Fund Shares. Trading in Fund Shares on the Exchange may be halted due to market conditions or for reasons that, in the view of the Exchange, make trading in Fund Shares inadvisable. In addition, trading in Fund Shares on the Exchange is subject to trading halts caused by extraordinary market volatility pursuant to the Exchange’s “circuit breaker” rules. There can be no assurance that the requirements of the Exchange necessary to maintain the listing of the Fund will continue to be met or will remain unchanged.

Roundhill Semiconductor WeeklyPay™ ETF | U.S. GOVERNMENT SECURITIES RISK  
Prospectus [Line Items]  
Risk [Text Block]

U.S. GOVERNMENT SECURITIES RISK. U.S. government securities are subject to interest rate risk but generally do not involve the credit risks associated with investments in other types of debt securities. As a result, the yields available from U.S. government securities are generally lower than the yields available from other debt securities. U.S. government securities are guaranteed only as to the timely payment of interest and the payment of principal when held to maturity.

Roundhill Semiconductor WeeklyPay™ ETF | VALUATION RISK  
Prospectus [Line Items]  
Risk [Text Block]

VALUATION RISK. The Fund may hold securities or other assets that may be valued on the basis of factors other than market quotations. This may occur because the asset or security does not trade on a centralized exchange, or in times of market turmoil or reduced liquidity. There are multiple methods that can be used to value a portfolio holding when market quotations are not readily available. The value established for any portfolio holding at a point in time might differ from what would be produced using a different methodology or if it had been priced using market quotations. Portfolio holdings that are valued using techniques other than market quotations, including “fair valued” assets or securities, may be subject to greater fluctuation in their valuations from one day to the next than if market quotations were used. In addition, there is no assurance that the Fund could sell or close out a portfolio position for the value established for it at any time, and it is possible that the Fund would incur a loss because a portfolio position is sold or closed out at a discount to the valuation established by the Fund at that time. The Fund’s ability to value investments may be impacted by technological issues or errors by pricing services or other third-party service providers.

Roundhill Semiconductor WeeklyPay™ ETF | EQUITY SECURITIES RISK  
Prospectus [Line Items]  
Risk [Text Block]

EQUITY SECURITIES RISK. Equity securities are subject to changes in value, and their values may be more volatile than those of other asset classes. Equity securities prices fluctuate for several reasons, including changes in investors’ perceptions of the financial condition of an issuer or the general condition of the relevant equity market, such as market volatility, or when political or economic events affecting an issuer occur. Common stock prices may be particularly sensitive to rising interest rates, as the cost of capital rises and borrowing costs increase. Common stocks generally subject their holders to more risks than preferred stocks and debt securities because common stockholders’ claims are subordinated to those of holders of preferred stocks and debt securities upon the bankruptcy of the issuer.

Roundhill Semiconductor WeeklyPay™ ETF | SWAP AGREEMENTS RISK  
Prospectus [Line Items]  
Risk [Text Block]

SWAP AGREEMENTS RISK. The Fund will utilize swap agreements to derive its exposure to shares of the Semiconductor ETF. Swap agreements may involve greater risks than direct investment in securities as they may be leveraged and are subject to credit risk, counterparty risk and valuation risk. A swap agreement could result in losses if the underlying reference or asset does not perform as anticipated. In addition, many swaps trade over-the-counter and may be considered illiquid. It may not be possible for the Fund to liquidate a swap position at an advantageous time or price, which may result in significant losses.

Roundhill Semiconductor WeeklyPay™ ETF | NEW FUND RISK  
Prospectus [Line Items]

NEW FUND RISK. The Fund is a recently organized investment company with a limited operating history. As a result, prospective investors have a limited track record or history on which to base their investment decision.

Roundhill Semiconductor WeeklyPay™ ETF | REGULATED INVESTMENT COMPANY TAX RISKS  
Prospectus [Line Items]  
Risk [Text Block]

REGULATED INVESTMENT COMPANY TAX RISKS. The Fund intends to qualify annually and to elect to be treated as a regulated investment company under the Internal Revenue Code of 1986, as amended (the “Code”). To qualify for the favorable U.S. federal income tax treatment generally accorded to regulated investment companies, the Fund must, among other things, (i) derive in each taxable year at least 90% of its gross income from dividends, interest, payments with respect to securities loans and gains from the sale or other disposition of stock, securities or foreign currencies or other income derived with respect to its business of investing in such stock, securities or currencies, or net income derived from interests in certain publicly traded partnerships; (ii) diversify its holdings so that, at the end of each quarter of the taxable year, (a) at least 50% of the market value of the Fund’s assets is represented by cash and cash items (including receivables), U.S. government securities, the securities of other regulated investment companies and other securities, with such other securities of any one issuer generally limited for the purposes of this calculation to an amount not greater than 5% of the value of the Fund’s total assets and not greater than 10% of the outstanding voting securities of such issuer, and (b) not more than 25% of the value of its total assets is invested in the securities (other than U.S. government securities or the securities of other regulated investment companies) of any one issuer, or two or more issuers which the Fund controls which are engaged in the same, similar or related trades or businesses, or the securities of one or more of certain publicly traded partnerships; and (iii) distribute at least 90% of its investment company taxable income (which includes, among other items, dividends, interest and net short-term capital gains in excess of net long-term capital losses) and at least 90% of its net tax-exempt interest income each taxable year. There are certain exceptions for failure to qualify if the failure is for reasonable cause or is de minimis, and certain corrective action is taken and certain tax payments are made by the Fund.

 

If the Fund were to fail to meet the qualifying income test or asset diversification test and fail to qualify as a RIC, it would be taxed in the same manner as an ordinary corporation, and distributions to its shareholders would not be deductible by the Fund in computing its taxable income, which would adversely affect the Fund’s performance.

Roundhill Semiconductor WeeklyPay™ ETF | LARGE SHAREHOLDER RISK  
Prospectus [Line Items]  
Risk [Text Block]

LARGE SHAREHOLDER RISK. Certain shareholders, including affiliated funds advised by the Adviser, may from time to time own a significant portion of the Fund’s shares. In addition, a third-party investor, the Adviser or an affiliate of the Adviser (“Affiliate”), an authorized participant, a market maker, or another entity may invest in the Fund and hold its investment for a limited period solely to facilitate the commencement of the Fund or to help the Fund achieve a specified size or scale. There can be no assurance that any large shareholder will not redeem its investment, that the size of the Fund will be maintained at such levels, or that the Fund will continue to meet applicable listing requirements. Redemptions by large shareholders could have a significant negative impact on the Fund. In addition, transactions by large shareholders may account for a large percentage of the trading volume on the Fund’s listing exchange and may, therefore, have a material upward or downward effect on the market price of the shares.

 

To the extent that a significant percentage of the Fund’s shares are owned or controlled by a small number of account shareholders (or a single account shareholder), including funds or accounts over which the Adviser or an Affiliate has investment discretion, the Fund is subject to the risk that those shareholders may purchase or redeem Fund shares in significant amounts rapidly or unexpectedly, including as a result of an asset allocation decision made by the Adviser or an Affiliate. This may adversely affect the Fund’s performance if the Adviser is forced to sell portfolio securities or invest cash when it would not otherwise choose to do so. Redemptions of a large number of shares may affect the liquidity of the Fund’s portfolio, increase the Fund’s transaction costs, and accelerate the realization of taxable income and/or gains. In addition, a large redemption could result in the Fund’s current expenses being allocated over a smaller asset base, leading to an increase in the Fund’s gross expense ratio. Large purchases of the Fund’s shares may also adversely affect the Fund’s performance to the extent that the Fund is delayed in investing new cash or otherwise maintains a larger cash position than it ordinarily would, particularly if the Fund accepts cash for an order for the purchase of creation units of the Fund’s shares.

Roundhill Semiconductor WeeklyPay™ ETF | SEMICONDUCTOR ETF INVESTING RISKS  
Prospectus [Line Items]  
Risk [Text Block]

SEMICONDUCTOR ETF INVESTING RISKS. The Fund will have significant exposure to the Semiconductor ETF through its investments in shares of the Semiconductor ETF and swap agreements that utilize the Semiconductor ETF as the reference asset. Accordingly, the Fund will subject to the risks of the Semiconductor ETF, set forth below. In addition to these risks, the Semiconductor ETF is also subject to the following risks to which the Fund is also subject, which are described within the section entitled “Principal Risks”: Market Risk, Asset Class Risk, Concentration Risk, Current Market Conditions Risk, Cybersecurity Risk, Equity Securities Risk, Operational Risk and Structural ETF Risk.

 

INDEX-RELATED RISK. The Semiconductor ETF Index Provider may rely on various sources of information to assess the criteria of components of the Semiconductor ETF Index, including information that may be based on assumptions and estimates. Neither the Semiconductor ETF nor its investment adviser offer assurances that the Semiconductor ETF Index Provider’s methodology or sources of information will provide an accurate assessment of included components or will result in the Semiconductor ETF meeting its investment objective. Errors in index data, index computations or the construction of the Semiconductor ETF Index in accordance with its methodology may occur, and the Semiconductor ETF Index Provider may not identify or correct them promptly or at all, which may have an adverse impact on the Semiconductor ETF and its shareholders. Unusual market conditions or other unforeseen circumstances (such as natural disasters, political unrest or war) may impact the Semiconductor ETF Index Provider or a third-party data provider and could cause the Semiconductor ETF Index Provider to postpone a scheduled rebalance. This could cause the Semiconductor ETF Index to vary from its normal or expected composition.

 

INDIRECT INVESTMENT RISK. The Semiconductor ETF is not affiliated with the Trust, the Fund, the Adviser, the Sub-Adviser or any affiliates thereof and is not involved with this offering in any way, and has no obligation to consider the Fund in taking any actions that might affect the value of the Fund. The Trust, the Fund, the Adviser, the Sub-Adviser or any affiliate are not responsible for the performance of the Semiconductor ETF and make no representation as to the performance of the Semiconductor ETF. Investing in the Fund is not equivalent to investing in the Semiconductor ETF Fund shareholders will not have voting rights or rights to receive dividends or other distributions or any other rights with respect to the Semiconductor ETF.

 

MID-CAPITALIZATION COMPANIES RISK. Compared to large capitalization companies, mid-capitalization companies may be less stable and more susceptible to adverse developments. The securities of mid-capitalization companies may be more volatile and less liquid than those of large-capitalization companies. As a result, the Semiconductor ETF’s share price may be more volatile than that of a fund with a greater investment in large-capitalization stocks.

 

LARGE CAPITALIZATION COMPANIES RISK. Large capitalization companies may be less able than smaller capitalization companies to adapt to changing market conditions. Large capitalization companies may be more mature and subject to more limited growth potential compared with smaller capitalization companies. During different market cycles, the performance of large capitalization companies has trailed the overall performance of the broader securities markets.

 

SEMI-CONDUCTOR COMPANIES RISK. Semiconductor companies face intense competition, both domestically and internationally, and such competition may have an adverse effect on profit margins. Semiconductor companies may have limited product lines, markets, financial resources or personnel. Semiconductor companies’ supply chain and operations are dependent on the availability of materials that meet exacting standards and the use of third parties to provide components and services. Semiconductor companies may rely on a limited number of suppliers, or upon suppliers in a single location, for certain materials, equipment or tools. Finding and qualifying alternate or additional suppliers can be a lengthy process that can cause production delays or impose unforeseen costs, and such alternatives may not be available at all. Production can be disrupted by the unavailability of resources, such as water, silicon, electricity, gases and other materials. Suppliers may also increase prices or encounter cybersecurity or other issues that can disrupt production or increase production costs. The products of semiconductor companies may face obsolescence due to rapid technological developments and frequent new product introduction, unpredictable changes in growth rates and competition for the services of qualified personnel. Capital equipment expenditures could be substantial, and equipment generally suffers from rapid obsolescence. Companies in the semiconductor industry are heavily dependent on patent and intellectual property rights. The loss or impairment of these rights, would adversely affect the profitability of these companies.

 

UNITED STATES RISK. Certain changes in the U.S. economy, such as when the U.S. economy weakens or when its financial markets decline, may have an adverse effect on the securities to which the Fund has exposure.

Risk [Text Block]

NON-DIVERSIFICATION RISK. As a “non-diversified” fund, the Fund may hold a smaller number of portfolio securities than many other funds. To the extent the Fund invests in a relatively small number of issuers, a decline in the market value of a particular security held by the Fund may affect its value more than if it invested in a larger number of issuers. The value of the Fund Shares may be more volatile than the values of shares of more diversified funds.

Roundhill S&P 500® WeeklyPay™ ETF | MARKET RISK  
Prospectus [Line Items]  
Risk [Text Block]

MARKET RISK. Market risk is the risk that a particular investment, or Fund Shares in general, may fall in value. Securities are subject to market fluctuations caused by real or perceived adverse economic, political, and regulatory factors or market developments, changes in interest rates, disruptions to trade, impositions of tariffs and perceived trends in securities prices. Fund Shares could decline in value or underperform other investments. In addition, local, regional or global events such as war, acts of terrorism, market manipulation, government defaults, government shutdowns, regulatory actions, political changes, diplomatic developments, the imposition of sanctions and other similar measures, spread of infectious diseases or other public health issues, recessions, natural disasters, or other events could have a significant negative impact on the Fund and its investments. Any of such circumstances could have a materially negative impact on the value of Fund Shares, the liquidity of an investment, and may result in increased market volatility. During any such events, Fund Shares may trade at increased premiums or discounts to their net asset value, the bid/ask spread on Fund Shares may widen and the returns on investment may fluctuate.

Roundhill S&P 500® WeeklyPay™ ETF | LIQUIDITY RISK  
Prospectus [Line Items]  
Risk [Text Block]

LIQUIDITY RISK. The market for swap agreements that reference the S&P 500 ETF shares may be subject to periods of illiquidity. During such times it may be difficult or impossible to buy or sell a position at the desired price. Market disruptions or volatility can also make it difficult to find a counterparty willing to transact at a reasonable price and sufficient size. Illiquid markets may cause losses, which could be significant. The large size of the positions which the Fund may acquire increases the risk of illiquidity, may make its positions more difficult to liquidate, and may increase the losses incurred while trying to do so. Such large positions also may impact the price of swap agreements on the S&P 500 ETF shares.

Roundhill S&P 500® WeeklyPay™ ETF | ACTIVE MANAGEMENT RISK

ACTIVE MANAGEMENT RISK. The Fund is actively-managed and its performance reflects investment decisions that the Adviser and/or Sub-Adviser makes for the Fund. Such judgments about the Fund’s investments may prove to be incorrect. If the investments selected and the strategies employed by the Fund fail to produce the intended results, the Fund could underperform as compared to other funds with similar investment objectives and/or strategies, or could have negative returns.

ACTIVE MARKET RISK. Although Fund Shares are listed for trading on the Exchange, there can be no assurance that an active trading market for Fund Shares will develop or be maintained. Fund Shares trade on the Exchange at market prices that may be below, at or above the Fund’s net asset value. Securities, including Fund Shares, are subject to market fluctuations and liquidity constraints that may be caused by such factors as economic, political, or regulatory developments, changes in interest rates, and/or perceived trends in securities prices. Fund Shares could decline in value or underperform other investments.

Risk [Text Block]

CONCENTRATION RISK. The Fund is susceptible to an increased risk of loss, including losses due to adverse events that affect the Fund’s investments more than the market as a whole, to the extent that the Fund’s investments are concentrated in investments that provide exposure to the S&P 500 ETF and the industry or group of industries to which it is concentrated.

Prospectus [Line Items]  
Risk [Text Block]

COUNTERPARTY RISK. Fund transactions involving a counterparty are subject to the risk that the counterparty will not fulfill its obligation to the Fund. Counterparty risk may arise because of the counterparty’s financial condition (i.e., financial difficulties, bankruptcy, or insolvency), market activities and developments, or other reasons, whether foreseen or not. A counterparty’s inability to fulfill its obligation may result in significant financial loss to the Fund. The Fund may be unable to recover its investment from the counterparty or may obtain a limited recovery, and/or recovery may be delayed.

CREDIT RISK. An issuer or other obligated party of a debt security may be unable or unwilling to make dividend, interest and/or principal payments when due. In addition, the value of a debt security may decline because of concerns about the issuer’s ability or unwillingness to make such payments.

Roundhill S&P 500® WeeklyPay™ ETF | CURRENT MARKET CONDITIONS RISK  
Prospectus [Line Items]  
Risk [Text Block]

CURRENT MARKET CONDITIONS RISK. Current market conditions risk is the risk that a particular investment, or Fund Shares in general, may fall in value due to current market conditions. As a means to fight inflation, which remains at elevated levels, the Federal Reserve and certain foreign central banks have raised interest rates; however, the Federal Reserve has recently lowered interest rates and may continue to do so. U.S. regulators have proposed several changes to market and issuer regulations which would directly impact the Fund, and any regulatory changes could adversely impact the Fund’s ability to achieve its investment strategies or make certain investments. Recent and potential future bank failures could result in disruption to the broader banking industry or markets generally and reduce confidence in financial institutions and the economy as a whole, which may also heighten market volatility and reduce liquidity. Additionally, challenges in commercial real estate markets, including rising interest rates, declining valuations and increasing vacancies, could have a broader impact on financial markets. The ongoing adversarial political climate in the United States, as well as political and diplomatic events both domestic and abroad, have and may continue to have an adverse impact the U.S. regulatory landscape, markets and investor behavior, which could have a negative impact on the Fund’s investments and operations. The change in administration resulting from the 2024 United States national elections could result in significant impacts to international trade relations, tax and immigration policies, and other aspects of the national and international political and financial landscape, which could affect, among other things, inflation and the securities markets generally. Other unexpected political, regulatory and diplomatic events within the U.S. and abroad may affect investor and consumer confidence and may adversely impact financial markets and the broader economy. For example, ongoing armed conflicts between Russia and Ukraine in Europe and among Israel, Iran, Hamas and other militant groups in the Middle East, have caused and could continue to cause significant market disruptions and volatility within the markets in Russia, Europe, the Middle East and the United States. The hostilities and sanctions resulting from those hostilities have and could continue to have a significant impact on certain Fund investments as well as Fund performance and liquidity. The economies of the United States and its trading partners, as well as the financial markets generally, may be adversely impacted by trade disputes, including the imposition of tariffs, and other matters. For example, the United States has imposed trade barriers and restrictions on China. In addition, the Chinese government is engaged in a longstanding dispute with Taiwan, continually threatening an invasion. If the political climate between the United States and China does not improve or continues to deteriorate, if China were to attempt invading Taiwan, or if other geopolitical conflicts develop or worsen, economies, markets and individual securities may be adversely affected, and the value of the Fund’s assets may go down. A public health crisis and the ensuing policies enacted by governments and central banks may cause significant volatility and uncertainty in global financial markets, negatively impacting global growth prospects. As the COVID-19 global pandemic illustrated, such events may affect certain geographic regions, countries, sectors and industries more significantly than others. Advancements in technology may also adversely impact markets and the overall performance of the Fund. For instance, the economy may be significantly impacted by the advanced development and increased regulation of artificial intelligence. Additionally, cyber security breaches of both government and non-government entities could have negative impacts on infrastructure and the ability of such entities, including the Fund, to operate properly. These events, and any other future events, may adversely affect the prices and liquidity of the Fund’s portfolio investments and could result in disruptions in the trading markets.

Roundhill S&P 500® WeeklyPay™ ETF | CYBERSECURITY RISK  
Prospectus [Line Items]  
Risk [Text Block]

CYBERSECURITY RISK. Failures or breaches of the electronic systems of the Fund, the Fund’s adviser, sub-adviser, distributor and other service providers, market makers, Authorized Participants or the issuers of securities in which the Fund invests have the ability to cause disruptions, negatively impact the Fund’s business operations and/or potentially result in financial losses to the Fund and its shareholders. While the Fund has established business continuity plans and risk management systems seeking to address system breaches or failures, there are inherent limitations in such plans and systems. Furthermore, the Fund cannot control the cybersecurity plans and systems of the Fund’s other service providers, market makers, Authorized Participants or issuers of securities in which the Fund invests.

Roundhill S&P 500® WeeklyPay™ ETF | DEBT SECURITIES RISK  
Prospectus [Line Items]  
Risk [Text Block]

DEBT SECURITIES RISK. Investments in debt securities subject the holder to the credit risk of the issuer. Credit risk refers to the possibility that the issuer or other obligor of a security will not be able or willing to make payments of interest and principal when due. Generally, the value of debt securities will change inversely with changes in interest rates. To the extent that interest rates rise, certain underlying obligations may be paid off substantially slower than originally anticipated and the value of those securities may fall sharply. During periods of falling interest rates, the income received by the Fund may decline. If the principal on a debt security is prepaid before expected, the prepayments of principal may have to be reinvested in obligations paying interest at lower rates. Debt securities generally do not trade on a securities exchange making them generally less liquid and more difficult to value than common stock.

Roundhill S&P 500® WeeklyPay™ ETF | DERIVATIVES RISK  
Prospectus [Line Items]  
Risk [Text Block]

DERIVATIVES RISK. The use of derivative instruments involves risks different from, or possibly greater than, the risks associated with investing directly in securities and other traditional investments. These risks include: (i) the risk that the counterparty to a derivative transaction may not fulfill its contractual obligations; (ii) risk of mispricing or improper valuation; and (iii) the risk that changes in the value of the derivative may not correlate perfectly with the underlying asset. Derivative prices are highly volatile and may fluctuate substantially during a short period of time. Such prices are influenced by numerous factors that affect the markets, including, but not limited to: changing supply and demand relationships; government programs and policies; national and international political and economic events, changes in interest rates, inflation and deflation and changes in supply and demand relationships. Trading derivative instruments involves risks different from, or possibly greater than, the risks associated with investing directly in securities. Derivative contracts ordinarily have leverage inherent in their terms. The use of leverage may cause the Fund to liquidate portfolio positions when it would not be advantageous to do so in order to satisfy its obligations or to meet regulatory or contractual requirements for derivatives. The use of derivatives can magnify potential for gain or loss and, therefore, amplify the effects of market volatility on share price.

Roundhill S&P 500® WeeklyPay™ ETF | DISTRIBUTION TAX RISK  
Prospectus [Line Items]  
Risk [Text Block]

DISTRIBUTION TAX RISK. The Fund currently expects to make distributions on a weekly basis. Such frequent distributions may expose investors to increased tax liabilities. However, these distributions may exceed the Fund’s income and gains for the Fund’s taxable year. Distributions in excess of the Fund’s current and accumulated earnings and profits will be treated as a return of capital. A return of capital distribution generally will not be taxable but will reduce the shareholder’s cost basis and will result in a higher capital gain or lower capital loss when those Fund Shares on which the distribution was received are sold. Once a Fund shareholder’s cost basis is reduced to zero, further distributions will be treated as capital gain if the Fund shareholder holds Fund Shares as capital assets. Additionally, any capital returned through distributions will be distributed after payment of Fund fees and expenses. Because a portion of the Fund’s distributions may consist of return of capital, the Fund may not be an appropriate investment for investors who do not want their principal investment in the Fund to decrease over time or who do not wish to receive return of capital in a given period. In the event that a shareholder purchases Fund Shares shortly before a distribution by the Fund, the entire distribution may be taxable to the shareholder even though a portion of the distribution effectively represents a return of the purchase price.

Roundhill S&P 500® WeeklyPay™ ETF | ETF RISK  
Prospectus [Line Items]  
Risk [Text Block]

ETF RISK. The Fund may invest in ETFs. The value of an ETF held by the Fund will fluctuate over time based on fluctuations in the values of the assets held by the ETF, which may be affected by changes in general economic conditions, expectations for future growth and profits, interest rates and the supply and demand for those assets. When the Fund invests in an ETF, it will bear a proportionate share of the ETF’s expenses. Brokerage, tax and other expenses may negatively impact the performance of the ETF and, in turn, the value of the Fund Shares. An ETF that tracks an index may not exactly match the performance of the index due to cash drag, differences between the portfolio of the ETF and the components of the index, expenses and other factors.

Roundhill S&P 500® WeeklyPay™ ETF | INFLATION RISK  
Prospectus [Line Items]  
Risk [Text Block]

INFLATION RISK. Inflation risk is the risk that the value of assets or income from investments will be less in the future as inflation decreases the value of money. As inflation increases, the present value of the Fund’s assets and distributions may decline. This risk is more prevalent with respect to fixed income securities held by the Fund.

Roundhill S&P 500® WeeklyPay™ ETF | Interest Rate Risk [Member]  
Prospectus [Line Items]  
Risk [Text Block]

INTEREST RATE RISK. Interest rate risk is the risk that the value of the debt securities in the Fund’s portfolio will decline because of rising market interest rates. Interest rate risk is generally lower for shorter term debt securities and higher for longer-term debt securities. Duration is a reasonably accurate measure of a debt security’s price sensitivity to changes in interest rates and a common measure of interest rate risk. Duration measures a debt security’s expected life on a present value basis, taking into account the debt security’s yield, interest payments and final maturity. In general, duration represents the expected percentage change in the value of a security for an immediate 1% change in interest rates. For example, the price of a debt security with a three-year duration would be expected to drop by approximately 3% in response to a 1% increase in interest rates. Therefore, prices of debt securities with shorter durations tend to be less sensitive to interest rate changes than debt securities with longer durations. As the value of a debt security changes over time, so will its duration.

Roundhill S&P 500® WeeklyPay™ ETF | LEGISLATION AND LITIGATION RISK  
Prospectus [Line Items]  
Risk [Text Block]

LEGISLATION AND LITIGATION RISK. Legislation or litigation that affects the value of assets or securities held by the Fund may reduce the value of the Fund. From time to time, various legislative initiatives are proposed that may have a negative impact on certain assets or securities in which the Fund invests. In addition, litigation regarding any of the assets or securities owned by the Fund may negatively impact the value of the Shares. Such legislation or litigation may cause the Fund to lose value or may result in higher portfolio turnover if the Adviser determines to sell such a holding.

Roundhill S&P 500® WeeklyPay™ ETF | LEVERAGE RISK  
Prospectus [Line Items]  
Risk [Text Block]

LEVERAGE RISK. The Fund obtains investment exposure in excess of its net assets by utilizing leverage and may lose more money in market conditions that are adverse to its investment objectives than a fund that does not utilize leverage. An investment in the Fund is exposed to the risk that a decline in the weekly performance of shares of the S&P 500 ETF will be magnified. This means that an investment in the Fund will be reduced by an amount equal to 1.2% for every 1% weekly decline in the market value of the S&P 500 ETF shares, not including the costs of financing leverage and other operating expenses, which would further reduce its value. The Fund could theoretically lose an amount greater than its net assets in the event the market value of the S&P 500 ETF shares decline more than 83.33% over a calendar week. Leverage will also have the effect of magnifying any differences in the Fund’s correlation with the S&P 500 ETF shares.

Roundhill S&P 500® WeeklyPay™ ETF | MONEY MARKET INSTRUMENTS RISK  
Prospectus [Line Items]  
Risk [Text Block]

MONEY MARKET INSTRUMENTS RISK. The value of money market instruments may be affected by changing interest rates and by changes in the credit ratings of the investments. If a significant amount of the Fund’s assets are invested in money market instruments, it will be more difficult for the Fund to achieve its investment objectives. An investment in a money market fund is not insured or guaranteed by the FDIC or any other government agency. It is possible to lose money by investing in a money market fund.

Roundhill S&P 500® WeeklyPay™ ETF | OPERATIONAL RISK  
Prospectus [Line Items]  
Risk [Text Block]

OPERATIONAL RISK. The Fund is subject to risks arising from various operational factors, including, but not limited to, human error, processing and communication errors, errors of the Fund’s service providers, counterparties or other third-parties, failed or inadequate processes and technology or systems failures. The Fund relies on third-parties for a range of services, including custody. Any delay or failure relating to engaging or maintaining such service providers may affect the Fund’s ability to meet its investment objectives. Although the Fund and the Adviser seek to reduce these operational risks through controls and procedures, there is no way to completely protect against such risks.

Roundhill S&P 500® WeeklyPay™ ETF | SPECIAL TAX RISK  
Prospectus [Line Items]  
Risk [Text Block]

SPECIAL TAX RISK. The Fund intends to qualify annually and to elect to be treated as a regulated investment company under the Internal Revenue Code of 1986, as amended (the “Code”). To qualify for the favorable U.S. federal income tax treatment generally accorded to regulated investment companies, the Fund must, among other things, (i) derive in each taxable year at least 90% of its gross income from dividends, interest, payments with respect to securities loans and gains from the sale or other disposition of stock, securities or foreign currencies or other income derived with respect to its business of investing in such stock, securities or currencies, or net income derived from interests in certain publicly traded partnerships; (ii) diversify its holdings so that, at the end of each quarter of the taxable year, (a) at least 50% of the market value of the Fund’s assets is represented by cash and cash items (including receivables), U.S. government securities, the securities of other regulated investment companies and other securities, with such other securities of any one issuer generally limited for the purposes of this calculation to an amount not greater than 5% of the value of the Fund’s total assets and not greater than 10% of the outstanding voting securities of such issuer, and (b) not more than 25% of the value of its total assets is invested in the securities (other than U.S. government securities or the securities of other regulated investment companies) of any one issuer, or two or more issuers which the Fund controls which are engaged in the same, similar or related trades or businesses, or the securities of one or more of certain publicly traded partnerships; and (iii) distribute at least 90% of its investment company taxable income (which includes, among other items, dividends, interest and net short-term capital gains in excess of net long-term capital losses) and at least 90% of its net tax-exempt interest income each taxable year. There are certain exceptions for failure to qualify if the failure is for reasonable cause or is de minimis, and certain corrective action is taken and certain tax payments are made by the Fund.

 

The authority with regard to swaps entered into by regulated investment companies is unclear both as to the qualification under the income test and the identification of the issuer under the diversification test. The Fund intends to take the position that because the swaps held by the Fund reference securities that the income on the swaps are “other income” from the Fund’s business of investing in stocks and securities. In addition, the Fund intends to manage its investments in the swaps so that neither the exposure to issuer of the referenced security nor the exposure to any one counterparty of the swaps will exceed 25% of the gross value of the Fund’s portfolio at the end of any quarter.

 

If the Fund were to fail to meet the qualifying income test or asset diversification test and fail to qualify as a RIC, it would be taxed in the same manner as an ordinary corporation, and distributions to its shareholders would not be deductible by the Fund in computing its taxable income, which would adversely affect the Fund’s performance.

Roundhill S&P 500® WeeklyPay™ ETF | STRUCTURAL ETF RISKS  
Prospectus [Line Items]  
Risk [Text Block]

STRUCTURAL ETF RISKS. The Fund is an ETF. Accordingly, it is subject to certain risks associated with its unique structure.

 

Market Participants Risk. Only an Authorized Participant may engage in creation or redemption transactions directly with the Fund, and none of those Authorized Participants is obligated to engage in creation and/or redemption transactions. The Fund has a limited number of institutions that may act as Authorized Participants on an agency basis (i.e., on behalf of other market participants). To the extent that Authorized Participants exit the business or are unable to proceed with creation or redemption orders with respect to the Fund and no other Authorized Participant is able to step forward to create or redeem, Fund Shares may be more likely to trade at a premium or discount to NAV and possibly face trading halts or delisting. The Fund may also rely on a small number of third-party market makers to provide a market for the purchase and sale of Fund Shares but such market makers are under no obligation to do so. Decisions by Authorized Participants or market makers to reduce their role or step away from these activities in times of market stress could inhibit the effectiveness of the arbitrage process in maintaining the relationship between the underlying values of the Fund’s portfolio securities and the Fund’s market price. Any trading halt or other problem relating to the trading activity of these market makers or any issues disrupting the Authorized Participants’ ability to proceed with creation and/or redemption orders could result in a dramatic change in the spread between the Fund’s net asset value and the price at which Fund Shares are trading on the Exchange, which could result in a decrease in value of Fund Shares. This reduced effectiveness could result in Fund Shares trading at a premium or discount to net asset value and also in greater than normal intraday bid-ask spreads Fund Shares.

 

Cash Transactions Risk. The Fund currently expects to effect a significant portion of its creations and redemptions for cash, rather than in-kind securities. Paying redemption proceeds in cash rather than through in-kind delivery of portfolio securities may require the Fund to dispose of or sell portfolio securities or other assets at an inopportune time to obtain the cash needed to meet redemption orders. This may cause the Fund to sell a security and recognize a capital gain or loss that might not have been incurred if it had made a redemption in-kind. As a result, the Fund may pay out higher or lower annual capital gains distributions than ETFs that redeem in-kind. The use of cash creations and redemptions may also cause the Fund’s Shares to trade in the market at greater bid-ask spreads or greater premiums or discounts to the Fund’s NAV. Furthermore, the Fund may not be able to execute cash transactions for creation and redemption purposes at the same price used to determine the Fund’s NAV. To the extent that the maximum additional charge for creation or redemption transactions is insufficient to cover the execution shortfall, the Fund’s performance could be negatively impacted.

 

Costs of Buying and Selling Fund Shares. Due to the costs of buying or selling Fund Shares, including brokerage commissions imposed by brokers and bid/ask spreads, frequent trading of Fund Shares may significantly reduce investment results and an investment in Fund Shares may not be advisable for investors who anticipate regularly making small investments.

 

Premium/Discount Risk. As with all ETFs, Fund Shares may be bought and sold in the secondary market at market prices. The trading prices of Fund Shares in the secondary market may differ from the Fund’s daily net asset value per share and there may be times when the market price of the shares is more than the net asset value per share (premium) or less than the net asset value per share (discount). If a shareholder purchases Fund Shares at a time when the market price is at a premium to the net asset value or sells Fund Shares at a time when the market price is at a discount to the net asset value, the shareholder may pay more for, or receive less than, the underlying value of the Fund Shares, respectively. This risk is heightened in times of market volatility or periods of steep market declines.

 

Trading Risks. Although Fund Shares are listed for trading on the Exchange and may be traded on U.S. exchanges other than the Exchange, there can be no assurance that Fund Shares will trade with any volume, or at all, on any stock exchange. In stressed market conditions, the liquidity of Fund Shares may begin to mirror the liquidity of the Fund’s underlying portfolio holdings, which can be significantly less liquid than Fund Shares. Trading in Fund Shares on the Exchange may be halted due to market conditions or for reasons that, in the view of the Exchange, make trading in Fund Shares inadvisable. In addition, trading in Fund Shares on the Exchange is subject to trading halts caused by extraordinary market volatility pursuant to the Exchange’s “circuit breaker” rules. There can be no assurance that the requirements of the Exchange necessary to maintain the listing of the Fund will continue to be met or will remain unchanged.

Roundhill S&P 500® WeeklyPay™ ETF | U.S. GOVERNMENT SECURITIES RISK  
Prospectus [Line Items]  
Risk [Text Block]

U.S. GOVERNMENT SECURITIES RISK. U.S. government securities are subject to interest rate risk but generally do not involve the credit risks associated with investments in other types of debt securities. As a result, the yields available from U.S. government securities are generally lower than the yields available from other debt securities. U.S. government securities are guaranteed only as to the timely payment of interest and the payment of principal when held to maturity.

Roundhill S&P 500® WeeklyPay™ ETF | VALUATION RISK  
Prospectus [Line Items]  
Risk [Text Block]

VALUATION RISK. The Fund may hold securities or other assets that may be valued on the basis of factors other than market quotations. This may occur because the asset or security does not trade on a centralized exchange, or in times of market turmoil or reduced liquidity. There are multiple methods that can be used to value a portfolio holding when market quotations are not readily available. The value established for any portfolio holding at a point in time might differ from what would be produced using a different methodology or if it had been priced using market quotations. Portfolio holdings that are valued using techniques other than market quotations, including “fair valued” assets or securities, may be subject to greater fluctuation in their valuations from one day to the next than if market quotations were used. In addition, there is no assurance that the Fund could sell or close out a portfolio position for the value established for it at any time, and it is possible that the Fund would incur a loss because a portfolio position is sold or closed out at a discount to the valuation established by the Fund at that time. The Fund’s ability to value investments may be impacted by technological issues or errors by pricing services or other third-party service providers.

Roundhill S&P 500® WeeklyPay™ ETF | EQUITY SECURITIES RISK  
Prospectus [Line Items]  
Risk [Text Block]

EQUITY SECURITIES RISK. Equity securities are subject to changes in value, and their values may be more volatile than those of other asset classes. Equity securities prices fluctuate for several reasons, including changes in investors’ perceptions of the financial condition of an issuer or the general condition of the relevant equity market, such as market volatility, or when political or economic events affecting an issuer occur. Common stock prices may be particularly sensitive to rising interest rates, as the cost of capital rises and borrowing costs increase. Common stocks generally subject their holders to more risks than preferred stocks and debt securities because common stockholders’ claims are subordinated to those of holders of preferred stocks and debt securities upon the bankruptcy of the issuer.

Roundhill S&P 500® WeeklyPay™ ETF | SWAP AGREEMENTS RISK  
Prospectus [Line Items]  
Risk [Text Block]

SWAP AGREEMENTS RISK. The Fund will utilize swap agreements to derive its exposure to shares of the S&P 500 ETF. Swap agreements may involve greater risks than direct investment in securities as they may be leveraged and are subject to credit risk, counterparty risk and valuation risk. A swap agreement could result in losses if the underlying reference or asset does not perform as anticipated. In addition, many swaps trade over-the-counter and may be considered illiquid. It may not be possible for the Fund to liquidate a swap position at an advantageous time or price, which may result in significant losses.

Roundhill S&P 500® WeeklyPay™ ETF | NEW FUND RISK

NEW FUND RISK. The Fund is a recently organized investment company with a limited operating history. As a result, prospective investors have a limited track record or history on which to base their investment decision.

REGULATED INVESTMENT COMPANY TAX RISKS. The Fund intends to qualify annually and to elect to be treated as a regulated investment company under the Internal Revenue Code of 1986, as amended (the “Code”). To qualify for the favorable U.S. federal income tax treatment generally accorded to regulated investment companies, the Fund must, among other things, (i) derive in each taxable year at least 90% of its gross income from dividends, interest, payments with respect to securities loans and gains from the sale or other disposition of stock, securities or foreign currencies or other income derived with respect to its business of investing in such stock, securities or currencies, or net income derived from interests in certain publicly traded partnerships; (ii) diversify its holdings so that, at the end of each quarter of the taxable year, (a) at least 50% of the market value of the Fund’s assets is represented by cash and cash items (including receivables), U.S. government securities, the securities of other regulated investment companies and other securities, with such other securities of any one issuer generally limited for the purposes of this calculation to an amount not greater than 5% of the value of the Fund’s total assets and not greater than 10% of the outstanding voting securities of such issuer, and (b) not more than 25% of the value of its total assets is invested in the securities (other than U.S. government securities or the securities of other regulated investment companies) of any one issuer, or two or more issuers which the Fund controls which are engaged in the same, similar or related trades or businesses, or the securities of one or more of certain publicly traded partnerships; and (iii) distribute at least 90% of its investment company taxable income (which includes, among other items, dividends, interest and net short-term capital gains in excess of net long-term capital losses) and at least 90% of its net tax-exempt interest income each taxable year. There are certain exceptions for failure to qualify if the failure is for reasonable cause or is de minimis, and certain corrective action is taken and certain tax payments are made by the Fund.

 

If the Fund were to fail to meet the qualifying income test or asset diversification test and fail to qualify as a RIC, it would be taxed in the same manner as an ordinary corporation, and distributions to its shareholders would not be deductible by the Fund in computing its taxable income, which would adversely affect the Fund’s performance.

Roundhill S&P 500® WeeklyPay™ ETF | LARGE SHAREHOLDER RISK  
Prospectus [Line Items]  
Risk [Text Block]

LARGE SHAREHOLDER RISK. Certain shareholders, including affiliated funds advised by the Adviser, may from time to time own a significant portion of the Fund’s shares. In addition, a third-party investor, the Adviser or an affiliate of the Adviser (“Affiliate”), an authorized participant, a market maker, or another entity may invest in the Fund and hold its investment for a limited period solely to facilitate the commencement of the Fund or to help the Fund achieve a specified size or scale. There can be no assurance that any large shareholder will not redeem its investment, that the size of the Fund will be maintained at such levels, or that the Fund will continue to meet applicable listing requirements. Redemptions by large shareholders could have a significant negative impact on the Fund. In addition, transactions by large shareholders may account for a large percentage of the trading volume on the Fund’s listing exchange and may, therefore, have a material upward or downward effect on the market price of the shares.

 

To the extent that a significant percentage of the Fund’s shares are owned or controlled by a small number of account shareholders (or a single account shareholder), including funds or accounts over which the Adviser or an Affiliate has investment discretion, the Fund is subject to the risk that those shareholders may purchase or redeem Fund shares in significant amounts rapidly or unexpectedly, including as a result of an asset allocation decision made by the Adviser or an Affiliate. This may adversely affect the Fund’s performance if the Adviser is forced to sell portfolio securities or invest cash when it would not otherwise choose to do so. Redemptions of a large number of shares may affect the liquidity of the Fund’s portfolio, increase the Fund’s transaction costs, and accelerate the realization of taxable income and/or gains. In addition, a large redemption could result in the Fund’s current expenses being allocated over a smaller asset base, leading to an increase in the Fund’s gross expense ratio. Large purchases of the Fund’s shares may also adversely affect the Fund’s performance to the extent that the Fund is delayed in investing new cash or otherwise maintains a larger cash position than it ordinarily would, particularly if the Fund accepts cash for an order for the purchase of creation units of the Fund’s shares.

Risk [Text Block]

S&P 500 ETF INVESTING RISKS. The Fund will have significant exposure to the S&P 500 ETF through its investments in shares of the S&P 500 ETF and swap agreements that utilize the S&P 500 ETF as the reference asset. Accordingly, the Fund will subject to the risks of the S&P 500 ETF, set forth below. In addition to these risks, the S&P 500 ETF is also subject to the following risks to which the Fund is also subject, which are described within the section entitled “Principal Risks”: Market Risk, Asset Class Risk, Concentration Risk, Current Market Conditions Risk, Cybersecurity Risk, Equity Securities Risk, Operational Risk and Structural ETF Risk.

 

INDEX-RELATED RISK. The S&P 500 ETF Index Provider may rely on various sources of information to assess the criteria of components of the S&P 500 ETF Index, including information that may be based on assumptions and estimates. Neither the S&P 500 ETF nor its investment adviser offer assurances that the S&P 500 ETF Index Provider’s methodology or sources of information will provide an accurate assessment of included components or will result in the S&P 500 ETF meeting its investment objective. Errors in index data, index computations or the construction of the S&P 500 ETF Index in accordance with its methodology may occur, and the S&P 500 ETF Index Provider may not identify or correct them promptly or at all, which may have an adverse impact on the S&P 500 ETF and its shareholders. Unusual market conditions or other unforeseen circumstances (such as natural disasters, political unrest or war) may impact the S&P 500 ETF Index Provider or a third-party data provider and could cause the S&P 500 ETF Index Provider to postpone a scheduled rebalance. This could cause the S&P 500 ETF Index to vary from its normal or expected composition.

 

INDIRECT INVESTMENT RISK. The S&P 500 ETF is not affiliated with the Trust, the Fund, the Adviser, the Sub-Adviser or any affiliates thereof and is not involved with this offering in any way, and has no obligation to consider the Fund in taking any actions that might affect the value of the Fund. The Trust, the Fund, the Adviser, the Sub-Adviser or any affiliate are not responsible for the performance of the S&P 500 ETF and make no representation as to the performance of the S&P 500 ETF. Investing in the Fund is not equivalent to investing in the S&P 500 ETF Fund shareholders will not have voting rights or rights to receive dividends or other distributions or any other rights with respect to the S&P 500 ETF.

 

LARGE CAPITALIZATION COMPANIES RISK. Large capitalization companies may be less able than smaller capitalization companies to adapt to changing market conditions. Large capitalization companies may be more mature and subject to more limited growth potential compared with smaller capitalization companies. During different market cycles, the performance of large capitalization companies has trailed the overall performance of the broader securities markets.

 

UNITED STATES RISK. Certain changes in the U.S. economy, such as when the U.S. economy weakens or when its financial markets decline, may have an adverse effect on the securities to which the Fund has exposure.

Risk [Text Block]

NON-DIVERSIFICATION RISK. As a “non-diversified” fund, the Fund may hold a smaller number of portfolio securities than many other funds. To the extent the Fund invests in a relatively small number of issuers, a decline in the market value of a particular security held by the Fund may affect its value more than if it invested in a larger number of issuers. The value of the Fund Shares may be more volatile than the values of shares of more diversified funds.

Roundhill Treasury Bond WeeklyPay™ ETF | MARKET RISK  
Prospectus [Line Items]  
Risk [Text Block]

MARKET RISK. Market risk is the risk that a particular investment, or Fund Shares in general, may fall in value. Securities are subject to market fluctuations caused by real or perceived adverse economic, political, and regulatory factors or market developments, changes in interest rates, disruptions to trade, impositions of tariffs and perceived trends in securities prices. Fund Shares could decline in value or underperform other investments. In addition, local, regional or global events such as war, acts of terrorism, market manipulation, government defaults, government shutdowns, regulatory actions, political changes, diplomatic developments, the imposition of sanctions and other similar measures, spread of infectious diseases or other public health issues, recessions, natural disasters, or other events could have a significant negative impact on the Fund and its investments. Any of such circumstances could have a materially negative impact on the value of Fund Shares, the liquidity of an investment, and may result in increased market volatility. During any such events, Fund Shares may trade at increased premiums or discounts to their net asset value, the bid/ask spread on Fund Shares may widen and the returns on investment may fluctuate.

Roundhill Treasury Bond WeeklyPay™ ETF | LIQUIDITY RISK  
Prospectus [Line Items]  
Risk [Text Block]

LIQUIDITY RISK. The market for swap agreements that reference the Treasury Bond ETF shares may be subject to periods of illiquidity. During such times it may be difficult or impossible to buy or sell a position at the desired price. Market disruptions or volatility can also make it difficult to find a counterparty willing to transact at a reasonable price and sufficient size. Illiquid markets may cause losses, which could be significant. The large size of the positions which the Fund may acquire increases the risk of illiquidity, may make its positions more difficult to liquidate, and may increase the losses incurred while trying to do so. Such large positions also may impact the price of swap agreements on the Treasury Bond ETF shares.

Roundhill Treasury Bond WeeklyPay™ ETF | ACTIVE MANAGEMENT RISK  
Prospectus [Line Items]  
Risk [Text Block]

ACTIVE MANAGEMENT RISK. The Fund is actively-managed and its performance reflects investment decisions that the Adviser and/or Sub-Adviser makes for the Fund. Such judgments about the Fund’s investments may prove to be incorrect. If the investments selected and the strategies employed by the Fund fail to produce the intended results, the Fund could underperform as compared to other funds with similar investment objectives and/or strategies, or could have negative returns.

Roundhill Treasury Bond WeeklyPay™ ETF | ACTIVE MARKET RISK

ACTIVE MARKET RISK. Although Fund Shares are listed for trading on the Exchange, there can be no assurance that an active trading market for Fund Shares will develop or be maintained. Fund Shares trade on the Exchange at market prices that may be below, at or above the Fund’s net asset value. Securities, including Fund Shares, are subject to market fluctuations and liquidity constraints that may be caused by such factors as economic, political, or regulatory developments, changes in interest rates, and/or perceived trends in securities prices. Fund Shares could decline in value or underperform other investments.

CONCENTRATION RISK. The Fund is susceptible to an increased risk of loss, including losses due to adverse events that affect the Fund’s investments more than the market as a whole, to the extent that the Fund’s investments are concentrated in investments that provide exposure to the Treasury Bond ETF and the industry or group of industries to which it is concentrated.

Roundhill Treasury Bond WeeklyPay™ ETF | COUNTERPARTY RISK

Risk [Text Block]

COUNTERPARTY RISK. Fund transactions involving a counterparty are subject to the risk that the counterparty will not fulfill its obligation to the Fund. Counterparty risk may arise because of the counterparty’s financial condition (i.e., financial difficulties, bankruptcy, or insolvency), market activities and developments, or other reasons, whether foreseen or not. A counterparty’s inability to fulfill its obligation may result in significant financial loss to the Fund. The Fund may be unable to recover its investment from the counterparty or may obtain a limited recovery, and/or recovery may be delayed.

Roundhill Treasury Bond WeeklyPay™ ETF | CURRENT MARKET CONDITIONS RISK  
Prospectus [Line Items]  
Risk [Text Block]

CURRENT MARKET CONDITIONS RISK. Current market conditions risk is the risk that a particular investment, or Fund Shares in general, may fall in value due to current market conditions. As a means to fight inflation, which remains at elevated levels, the Federal Reserve and certain foreign central banks have raised interest rates; however, the Federal Reserve has recently lowered interest rates and may continue to do so. U.S. regulators have proposed several changes to market and issuer regulations which would directly impact the Fund, and any regulatory changes could adversely impact the Fund’s ability to achieve its investment strategies or make certain investments. Recent and potential future bank failures could result in disruption to the broader banking industry or markets generally and reduce confidence in financial institutions and the economy as a whole, which may also heighten market volatility and reduce liquidity. Additionally, challenges in commercial real estate markets, including rising interest rates, declining valuations and increasing vacancies, could have a broader impact on financial markets. The ongoing adversarial political climate in the United States, as well as political and diplomatic events both domestic and abroad, have and may continue to have an adverse impact the U.S. regulatory landscape, markets and investor behavior, which could have a negative impact on the Fund’s investments and operations. The change in administration resulting from the 2024 United States national elections could result in significant impacts to international trade relations, tax and immigration policies, and other aspects of the national and international political and financial landscape, which could affect, among other things, inflation and the securities markets generally. Other unexpected political, regulatory and diplomatic events within the U.S. and abroad may affect investor and consumer confidence and may adversely impact financial markets and the broader economy. For example, ongoing armed conflicts between Russia and Ukraine in Europe and among Israel, Iran, Hamas and other militant groups in the Middle East, have caused and could continue to cause significant market disruptions and volatility within the markets in Russia, Europe, the Middle East and the United States. The hostilities and sanctions resulting from those hostilities have and could continue to have a significant impact on certain Fund investments as well as Fund performance and liquidity. The economies of the United States and its trading partners, as well as the financial markets generally, may be adversely impacted by trade disputes, including the imposition of tariffs, and other matters. For example, the United States has imposed trade barriers and restrictions on China. In addition, the Chinese government is engaged in a longstanding dispute with Taiwan, continually threatening an invasion. If the political climate between the United States and China does not improve or continues to deteriorate, if China were to attempt invading Taiwan, or if other geopolitical conflicts develop or worsen, economies, markets and individual securities may be adversely affected, and the value of the Fund’s assets may go down. A public health crisis and the ensuing policies enacted by governments and central banks may cause significant volatility and uncertainty in global financial markets, negatively impacting global growth prospects. As the COVID-19 global pandemic illustrated, such events may affect certain geographic regions, countries, sectors and industries more significantly than others. Advancements in technology may also adversely impact markets and the overall performance of the Fund. For instance, the economy may be significantly impacted by the advanced development and increased regulation of artificial intelligence. Additionally, cyber security breaches of both government and non-government entities could have negative impacts on infrastructure and the ability of such entities, including the Fund, to operate properly. These events, and any other future events, may adversely affect the prices and liquidity of the Fund’s portfolio investments and could result in disruptions in the trading markets.

Roundhill Treasury Bond WeeklyPay™ ETF | CYBERSECURITY RISK  
Prospectus [Line Items]  
Risk [Text Block]

CYBERSECURITY RISK. Failures or breaches of the electronic systems of the Fund, the Fund’s adviser, sub-adviser, distributor and other service providers, market makers, Authorized Participants or the issuers of securities in which the Fund invests have the ability to cause disruptions, negatively impact the Fund’s business operations and/or potentially result in financial losses to the Fund and its shareholders. While the Fund has established business continuity plans and risk management systems seeking to address system breaches or failures, there are inherent limitations in such plans and systems. Furthermore, the Fund cannot control the cybersecurity plans and systems of the Fund’s other service providers, market makers, Authorized Participants or issuers of securities in which the Fund invests.

Roundhill Treasury Bond WeeklyPay™ ETF | DEBT SECURITIES RISK  
Prospectus [Line Items]  
Risk [Text Block]

DEBT SECURITIES RISK. Investments in debt securities subject the holder to the credit risk of the issuer. Credit risk refers to the possibility that the issuer or other obligor of a security will not be able or willing to make payments of interest and principal when due. Generally, the value of debt securities will change inversely with changes in interest rates. To the extent that interest rates rise, certain underlying obligations may be paid off substantially slower than originally anticipated and the value of those securities may fall sharply. During periods of falling interest rates, the income received by the Fund may decline. If the principal on a debt security is prepaid before expected, the prepayments of principal may have to be reinvested in obligations paying interest at lower rates. Debt securities generally do not trade on a securities exchange making them generally less liquid and more difficult to value than common stock.

Roundhill Treasury Bond WeeklyPay™ ETF | DERIVATIVES RISK  
Prospectus [Line Items]  
Risk [Text Block]

DERIVATIVES RISK. The use of derivative instruments involves risks different from, or possibly greater than, the risks associated with investing directly in securities and other traditional investments. These risks include: (i) the risk that the counterparty to a derivative transaction may not fulfill its contractual obligations; (ii) risk of mispricing or improper valuation; and (iii) the risk that changes in the value of the derivative may not correlate perfectly with the underlying asset. Derivative prices are highly volatile and may fluctuate substantially during a short period of time. Such prices are influenced by numerous factors that affect the markets, including, but not limited to: changing supply and demand relationships; government programs and policies; national and international political and economic events, changes in interest rates, inflation and deflation and changes in supply and demand relationships. Trading derivative instruments involves risks different from, or possibly greater than, the risks associated with investing directly in securities. Derivative contracts ordinarily have leverage inherent in their terms. The use of leverage may cause the Fund to liquidate portfolio positions when it would not be advantageous to do so in order to satisfy its obligations or to meet regulatory or contractual requirements for derivatives. The use of derivatives can magnify potential for gain or loss and, therefore, amplify the effects of market volatility on share price.

Roundhill Treasury Bond WeeklyPay™ ETF | DISTRIBUTION TAX RISK  
Prospectus [Line Items]  
Risk [Text Block]

DISTRIBUTION TAX RISK. The Fund currently expects to make distributions on a weekly basis. Such frequent distributions may expose investors to increased tax liabilities. However, these distributions may exceed the Fund’s income and gains for the Fund’s taxable year. Distributions in excess of the Fund’s current and accumulated earnings and profits will be treated as a return of capital. A return of capital distribution generally will not be taxable but will reduce the shareholder’s cost basis and will result in a higher capital gain or lower capital loss when those Fund Shares on which the distribution was received are sold. Once a Fund shareholder’s cost basis is reduced to zero, further distributions will be treated as capital gain if the Fund shareholder holds Fund Shares as capital assets. Additionally, any capital returned through distributions will be distributed after payment of Fund fees and expenses. Because a portion of the Fund’s distributions may consist of return of capital, the Fund may not be an appropriate investment for investors who do not want their principal investment in the Fund to decrease over time or who do not wish to receive return of capital in a given period. In the event that a shareholder purchases Fund Shares shortly before a distribution by the Fund, the entire distribution may be taxable to the shareholder even though a portion of the distribution effectively represents a return of the purchase price.

Roundhill Treasury Bond WeeklyPay™ ETF | ETF RISK  
Prospectus [Line Items]  
Risk [Text Block]

ETF RISK. The Fund may invest in ETFs. The value of an ETF held by the Fund will fluctuate over time based on fluctuations in the values of the assets held by the ETF, which may be affected by changes in general economic conditions, expectations for future growth and profits, interest rates and the supply and demand for those assets. When the Fund invests in an ETF, it will bear a proportionate share of the ETF’s expenses. Brokerage, tax and other expenses may negatively impact the performance of the ETF and, in turn, the value of the Fund Shares. An ETF that tracks an index may not exactly match the performance of the index due to cash drag, differences between the portfolio of the ETF and the components of the index, expenses and other factors.

Roundhill Treasury Bond WeeklyPay™ ETF | INFLATION RISK  
Prospectus [Line Items]  
Risk [Text Block]

INFLATION RISK. Inflation risk is the risk that the value of assets or income from investments will be less in the future as inflation decreases the value of money. As inflation increases, the present value of the Fund’s assets and distributions may decline. This risk is more prevalent with respect to fixed income securities held by the Fund.

Roundhill Treasury Bond WeeklyPay™ ETF | Interest Rate Risk [Member]  
Prospectus [Line Items]  
Risk [Text Block]

INTEREST RATE RISK. Interest rate risk is the risk that the value of the debt securities in the Fund’s portfolio will decline because of rising market interest rates. Interest rate risk is generally lower for shorter term debt securities and higher for longer-term debt securities. Duration is a reasonably accurate measure of a debt security’s price sensitivity to changes in interest rates and a common measure of interest rate risk. Duration measures a debt security’s expected life on a present value basis, taking into account the debt security’s yield, interest payments and final maturity. In general, duration represents the expected percentage change in the value of a security for an immediate 1% change in interest rates. For example, the price of a debt security with a three-year duration would be expected to drop by approximately 3% in response to a 1% increase in interest rates. Therefore, prices of debt securities with shorter durations tend to be less sensitive to interest rate changes than debt securities with longer durations. As the value of a debt security changes over time, so will its duration.

Roundhill Treasury Bond WeeklyPay™ ETF | LEGISLATION AND LITIGATION RISK  
Prospectus [Line Items]  
Risk [Text Block]

LEGISLATION AND LITIGATION RISK. Legislation or litigation that affects the value of assets or securities held by the Fund may reduce the value of the Fund. From time to time, various legislative initiatives are proposed that may have a negative impact on certain assets or securities in which the Fund invests. In addition, litigation regarding any of the assets or securities owned by the Fund may negatively impact the value of the Shares. Such legislation or litigation may cause the Fund to lose value or may result in higher portfolio turnover if the Adviser determines to sell such a holding.

Roundhill Treasury Bond WeeklyPay™ ETF | LEVERAGE RISK  
Prospectus [Line Items]  
Risk [Text Block]

LEVERAGE RISK. The Fund obtains investment exposure in excess of its net assets by utilizing leverage and may lose more money in market conditions that are adverse to its investment objectives than a fund that does not utilize leverage. An investment in the Fund is exposed to the risk that a decline in the weekly performance of shares of the Treasury Bond ETF will be magnified. This means that an investment in the Fund will be reduced by an amount equal to 1.2% for every 1% weekly decline in the market value of the Treasury Bond ETF shares, not including the costs of financing leverage and other operating expenses, which would further reduce its value. The Fund could theoretically lose an amount greater than its net assets in the event the market value of the Treasury Bond ETF shares decline more than 83.33% over a calendar week. Leverage will also have the effect of magnifying any differences in the Fund’s correlation with the Treasury Bond ETF shares.

Roundhill Treasury Bond WeeklyPay™ ETF | MONEY MARKET INSTRUMENTS RISK  
Prospectus [Line Items]  
Risk [Text Block]

MONEY MARKET INSTRUMENTS RISK. The value of money market instruments may be affected by changing interest rates and by changes in the credit ratings of the investments. If a significant amount of the Fund’s assets are invested in money market instruments, it will be more difficult for the Fund to achieve its investment objectives. An investment in a money market fund is not insured or guaranteed by the FDIC or any other government agency. It is possible to lose money by investing in a money market fund.

Roundhill Treasury Bond WeeklyPay™ ETF | OPERATIONAL RISK  
Prospectus [Line Items]  
Risk [Text Block]

OPERATIONAL RISK. The Fund is subject to risks arising from various operational factors, including, but not limited to, human error, processing and communication errors, errors of the Fund’s service providers, counterparties or other third-parties, failed or inadequate processes and technology or systems failures. The Fund relies on third-parties for a range of services, including custody. Any delay or failure relating to engaging or maintaining such service providers may affect the Fund’s ability to meet its investment objectives. Although the Fund and the Adviser seek to reduce these operational risks through controls and procedures, there is no way to completely protect against such risks.

Roundhill Treasury Bond WeeklyPay™ ETF | SPECIAL TAX RISK  
Prospectus [Line Items]  
Risk [Text Block]

SPECIAL TAX RISK. The Fund intends to qualify annually and to elect to be treated as a regulated investment company under the Internal Revenue Code of 1986, as amended (the “Code”). To qualify for the favorable U.S. federal income tax treatment generally accorded to regulated investment companies, the Fund must, among other things, (i) derive in each taxable year at least 90% of its gross income from dividends, interest, payments with respect to securities loans and gains from the sale or other disposition of stock, securities or foreign currencies or other income derived with respect to its business of investing in such stock, securities or currencies, or net income derived from interests in certain publicly traded partnerships; (ii) diversify its holdings so that, at the end of each quarter of the taxable year, (a) at least 50% of the market value of the Fund’s assets is represented by cash and cash items (including receivables), U.S. government securities, the securities of other regulated investment companies and other securities, with such other securities of any one issuer generally limited for the purposes of this calculation to an amount not greater than 5% of the value of the Fund’s total assets and not greater than 10% of the outstanding voting securities of such issuer, and (b) not more than 25% of the value of its total assets is invested in the securities (other than U.S. government securities or the securities of other regulated investment companies) of any one issuer, or two or more issuers which the Fund controls which are engaged in the same, similar or related trades or businesses, or the securities of one or more of certain publicly traded partnerships; and (iii) distribute at least 90% of its investment company taxable income (which includes, among other items, dividends, interest and net short-term capital gains in excess of net long-term capital losses) and at least 90% of its net tax-exempt interest income each taxable year. There are certain exceptions for failure to qualify if the failure is for reasonable cause or is de minimis, and certain corrective action is taken and certain tax payments are made by the Fund.

 

The authority with regard to swaps entered into by regulated investment companies is unclear both as to the qualification under the income test and the identification of the issuer under the diversification test. The Fund intends to take the position that because the swaps held by the Fund reference securities that the income on the swaps are “other income” from the Fund’s business of investing in stocks and securities. In addition, the Fund intends to manage its investments in the swaps so that neither the exposure to issuer of the referenced security nor the exposure to any one counterparty of the swaps will exceed 25% of the gross value of the Fund’s portfolio at the end of any quarter.

 

If the Fund were to fail to meet the qualifying income test or asset diversification test and fail to qualify as a RIC, it would be taxed in the same manner as an ordinary corporation, and distributions to its shareholders would not be deductible by the Fund in computing its taxable income, which would adversely affect the Fund’s performance.

Roundhill Treasury Bond WeeklyPay™ ETF | STRUCTURAL ETF RISKS  
Prospectus [Line Items]  
Risk [Text Block]

STRUCTURAL ETF RISKS. The Fund is an ETF. Accordingly, it is subject to certain risks associated with its unique structure.

 

Market Participants Risk. Only an Authorized Participant may engage in creation or redemption transactions directly with the Fund, and none of those Authorized Participants is obligated to engage in creation and/or redemption transactions. The Fund has a limited number of institutions that may act as Authorized Participants on an agency basis (i.e., on behalf of other market participants). To the extent that Authorized Participants exit the business or are unable to proceed with creation or redemption orders with respect to the Fund and no other Authorized Participant is able to step forward to create or redeem, Fund Shares may be more likely to trade at a premium or discount to NAV and possibly face trading halts or delisting. The Fund may also rely on a small number of third-party market makers to provide a market for the purchase and sale of Fund Shares but such market makers are under no obligation to do so. Decisions by Authorized Participants or market makers to reduce their role or step away from these activities in times of market stress could inhibit the effectiveness of the arbitrage process in maintaining the relationship between the underlying values of the Fund’s portfolio securities and the Fund’s market price. Any trading halt or other problem relating to the trading activity of these market makers or any issues disrupting the Authorized Participants’ ability to proceed with creation and/or redemption orders could result in a dramatic change in the spread between the Fund’s net asset value and the price at which Fund Shares are trading on the Exchange, which could result in a decrease in value of Fund Shares. This reduced effectiveness could result in Fund Shares trading at a premium or discount to net asset value and also in greater than normal intraday bid-ask spreads Fund Shares.

 

Cash Transactions Risk. The Fund currently expects to effect a significant portion of its creations and redemptions for cash, rather than in-kind securities. Paying redemption proceeds in cash rather than through in-kind delivery of portfolio securities may require the Fund to dispose of or sell portfolio securities or other assets at an inopportune time to obtain the cash needed to meet redemption orders. This may cause the Fund to sell a security and recognize a capital gain or loss that might not have been incurred if it had made a redemption in-kind. As a result, the Fund may pay out higher or lower annual capital gains distributions than ETFs that redeem in-kind. The use of cash creations and redemptions may also cause the Fund’s Shares to trade in the market at greater bid-ask spreads or greater premiums or discounts to the Fund’s NAV. Furthermore, the Fund may not be able to execute cash transactions for creation and redemption purposes at the same price used to determine the Fund’s NAV. To the extent that the maximum additional charge for creation or redemption transactions is insufficient to cover the execution shortfall, the Fund’s performance could be negatively impacted.

 

Costs of Buying and Selling Fund Shares. Due to the costs of buying or selling Fund Shares, including brokerage commissions imposed by brokers and bid/ask spreads, frequent trading of Fund Shares may significantly reduce investment results and an investment in Fund Shares may not be advisable for investors who anticipate regularly making small investments.

 

Premium/Discount Risk. As with all ETFs, Fund Shares may be bought and sold in the secondary market at market prices. The trading prices of Fund Shares in the secondary market may differ from the Fund’s daily net asset value per share and there may be times when the market price of the shares is more than the net asset value per share (premium) or less than the net asset value per share (discount). If a shareholder purchases Fund Shares at a time when the market price is at a premium to the net asset value or sells Fund Shares at a time when the market price is at a discount to the net asset value, the shareholder may pay more for, or receive less than, the underlying value of the Fund Shares, respectively. This risk is heightened in times of market volatility or periods of steep market declines.

 

Trading Risks. Although Fund Shares are listed for trading on the Exchange and may be traded on U.S. exchanges other than the Exchange, there can be no assurance that Fund Shares will trade with any volume, or at all, on any stock exchange. In stressed market conditions, the liquidity of Fund Shares may begin to mirror the liquidity of the Fund’s underlying portfolio holdings, which can be significantly less liquid than Fund Shares. Trading in Fund Shares on the Exchange may be halted due to market conditions or for reasons that, in the view of the Exchange, make trading in Fund Shares inadvisable. In addition, trading in Fund Shares on the Exchange is subject to trading halts caused by extraordinary market volatility pursuant to the Exchange’s “circuit breaker” rules. There can be no assurance that the requirements of the Exchange necessary to maintain the listing of the Fund will continue to be met or will remain unchanged.

Roundhill Treasury Bond WeeklyPay™ ETF | U.S. GOVERNMENT SECURITIES RISK  
Prospectus [Line Items]  
Risk [Text Block]

U.S. GOVERNMENT SECURITIES RISK. U.S. government securities are subject to interest rate risk but generally do not involve the credit risks associated with investments in other types of debt securities. As a result, the yields available from U.S. government securities are generally lower than the yields available from other debt securities. U.S. government securities are guaranteed only as to the timely payment of interest and the payment of principal when held to maturity.

Roundhill Treasury Bond WeeklyPay™ ETF | VALUATION RISK  
Prospectus [Line Items]  
Risk [Text Block]

VALUATION RISK. The Fund may hold securities or other assets that may be valued on the basis of factors other than market quotations. This may occur because the asset or security does not trade on a centralized exchange, or in times of market turmoil or reduced liquidity. There are multiple methods that can be used to value a portfolio holding when market quotations are not readily available. The value established for any portfolio holding at a point in time might differ from what would be produced using a different methodology or if it had been priced using market quotations. Portfolio holdings that are valued using techniques other than market quotations, including “fair valued” assets or securities, may be subject to greater fluctuation in their valuations from one day to the next than if market quotations were used. In addition, there is no assurance that the Fund could sell or close out a portfolio position for the value established for it at any time, and it is possible that the Fund would incur a loss because a portfolio position is sold or closed out at a discount to the valuation established by the Fund at that time. The Fund’s ability to value investments may be impacted by technological issues or errors by pricing services or other third-party service providers.

Roundhill Treasury Bond WeeklyPay™ ETF | EQUITY SECURITIES RISK  
Prospectus [Line Items]  
Risk [Text Block]

EQUITY SECURITIES RISK. Equity securities are subject to changes in value, and their values may be more volatile than those of other asset classes. Equity securities prices fluctuate for several reasons, including changes in investors’ perceptions of the financial condition of an issuer or the general condition of the relevant equity market, such as market volatility, or when political or economic events affecting an issuer occur. Common stock prices may be particularly sensitive to rising interest rates, as the cost of capital rises and borrowing costs increase. Common stocks generally subject their holders to more risks than preferred stocks and debt securities because common stockholders’ claims are subordinated to those of holders of preferred stocks and debt securities upon the bankruptcy of the issuer.

Roundhill Treasury Bond WeeklyPay™ ETF | SWAP AGREEMENTS RISK  
Prospectus [Line Items]  
Risk [Text Block]

SWAP AGREEMENTS RISK. The Fund will utilize swap agreements to derive its exposure to shares of the Treasury Bond ETF. Swap agreements may involve greater risks than direct investment in securities as they may be leveraged and are subject to credit risk, counterparty risk and valuation risk. A swap agreement could result in losses if the underlying reference or asset does not perform as anticipated. In addition, many swaps trade over-the-counter and may be considered illiquid. It may not be possible for the Fund to liquidate a swap position at an advantageous time or price, which may result in significant losses.

Roundhill Treasury Bond WeeklyPay™ ETF | NEW FUND RISK

REGULATED INVESTMENT COMPANY TAX RISKS. The Fund intends to qualify annually and to elect to be treated as a regulated investment company under the Internal Revenue Code of 1986, as amended (the “Code”). To qualify for the favorable U.S. federal income tax treatment generally accorded to regulated investment companies, the Fund must, among other things, (i) derive in each taxable year at least 90% of its gross income from dividends, interest, payments with respect to securities loans and gains from the sale or other disposition of stock, securities or foreign currencies or other income derived with respect to its business of investing in such stock, securities or currencies, or net income derived from interests in certain publicly traded partnerships; (ii) diversify its holdings so that, at the end of each quarter of the taxable year, (a) at least 50% of the market value of the Fund’s assets is represented by cash and cash items (including receivables), U.S. government securities, the securities of other regulated investment companies and other securities, with such other securities of any one issuer generally limited for the purposes of this calculation to an amount not greater than 5% of the value of the Fund’s total assets and not greater than 10% of the outstanding voting securities of such issuer, and (b) not more than 25% of the value of its total assets is invested in the securities (other than U.S. government securities or the securities of other regulated investment companies) of any one issuer, or two or more issuers which the Fund controls which are engaged in the same, similar or related trades or businesses, or the securities of one or more of certain publicly traded partnerships; and (iii) distribute at least 90% of its investment company taxable income (which includes, among other items, dividends, interest and net short-term capital gains in excess of net long-term capital losses) and at least 90% of its net tax-exempt interest income each taxable year. There are certain exceptions for failure to qualify if the failure is for reasonable cause or is de minimis, and certain corrective action is taken and certain tax payments are made by the Fund.

 

If the Fund were to fail to meet the qualifying income test or asset diversification test and fail to qualify as a RIC, it would be taxed in the same manner as an ordinary corporation, and distributions to its shareholders would not be deductible by the Fund in computing its taxable income, which would adversely affect the Fund’s performance.

Roundhill Treasury Bond WeeklyPay™ ETF | LARGE SHAREHOLDER RISK  
Prospectus [Line Items]  
Risk [Text Block]

LARGE SHAREHOLDER RISK. Certain shareholders, including affiliated funds advised by the Adviser, may from time to time own a significant portion of the Fund’s shares. In addition, a third-party investor, the Adviser or an affiliate of the Adviser (“Affiliate”), an authorized participant, a market maker, or another entity may invest in the Fund and hold its investment for a limited period solely to facilitate the commencement of the Fund or to help the Fund achieve a specified size or scale. There can be no assurance that any large shareholder will not redeem its investment, that the size of the Fund will be maintained at such levels, or that the Fund will continue to meet applicable listing requirements. Redemptions by large shareholders could have a significant negative impact on the Fund. In addition, transactions by large shareholders may account for a large percentage of the trading volume on the Fund’s listing exchange and may, therefore, have a material upward or downward effect on the market price of the shares.

 

To the extent that a significant percentage of the Fund’s shares are owned or controlled by a small number of account shareholders (or a single account shareholder), including funds or accounts over which the Adviser or an Affiliate has investment discretion, the Fund is subject to the risk that those shareholders may purchase or redeem Fund shares in significant amounts rapidly or unexpectedly, including as a result of an asset allocation decision made by the Adviser or an Affiliate. This may adversely affect the Fund’s performance if the Adviser is forced to sell portfolio securities or invest cash when it would not otherwise choose to do so. Redemptions of a large number of shares may affect the liquidity of the Fund’s portfolio, increase the Fund’s transaction costs, and accelerate the realization of taxable income and/or gains. In addition, a large redemption could result in the Fund’s current expenses being allocated over a smaller asset base, leading to an increase in the Fund’s gross expense ratio. Large purchases of the Fund’s shares may also adversely affect the Fund’s performance to the extent that the Fund is delayed in investing new cash or otherwise maintains a larger cash position than it ordinarily would, particularly if the Fund accepts cash for an order for the purchase of creation units of the Fund’s shares.

Roundhill Treasury Bond WeeklyPay™ ETF | TREASURY BOND ETF INVESTING RISKS  
Prospectus [Line Items]  
Risk [Text Block]

TREASURY BOND ETF INVESTING RISKS. The Fund will have significant exposure to the Treasury Bond ETF through its investments in shares of the Treasury Bond ETF and swap agreements that utilize the Treasury Bond ETF as the reference asset. Accordingly, the Fund will subject to the risks of the Treasury Bond ETF, set forth below. In addition to these risks, the Treasury Bond ETF is also subject to the following risks to which the Fund is also subject, which are described within the section entitled “Principal Risks”: Market Risk, Asset Class Risk, Concentration Risk, Credit Risk, Current Market Conditions Risk, Cybersecurity Risk, Debt Securities Risk, ETF Risk, Interest Rate Risk, Operational Risk, Structural ETF Risk, U.S. Government Securities Risk and Valuation Risk.

 

INCOME RISK. The Treasury Bond ETF’s income may decline due to falling interest rates or other factors. This can occur because the Treasury Bond ETF may be required to invest in lower-yielding bonds when a bond in the Treasury Bond ETF’s portfolio matures, is near maturity, is called or is prepaid, when bonds in the Treasury Bond ETF Index are substituted, or when the Treasury Bond ETF otherwise needs to purchase additional bonds. The Treasury Bond ETF Index Provider’s substitution of bonds in the Treasury Bond ETF Index may occur, for example, when the time to maturity for the bond no longer matches the Treasury Bond ETF Index’s stated maturity guidelines.

 

INDEX-RELATED RISK. The Treasury Bond ETF Index Provider may rely on various sources of information to assess the criteria of components of the Treasury Bond ETF Index, including information that may be based on assumptions and estimates. Neither the Treasury Bond ETF nor its investment adviser offer assurances that the Treasury Bond ETF Index Provider’s methodology or sources of information will provide an accurate assessment of included components or will result in the Treasury Bond ETF meeting its investment objective. Errors in index data, index computations or the construction of the Treasury Bond ETF Index in accordance with its methodology may occur, and the Treasury Bond ETF Index Provider may not identify or correct them promptly or at all, which may have an adverse impact on the Treasury Bond ETF and its shareholders. Unusual market conditions or other unforeseen circumstances (such as natural disasters, political unrest or war) may impact the Treasury Bond ETF Index Provider or a third-party data provider and could cause the Treasury Bond ETF Index Provider to postpone a scheduled rebalance. This could cause the Treasury Bond ETF Index to vary from its normal or expected composition.

 

INDIRECT INVESTMENT RISK. The Treasury Bond ETF is not affiliated with the Trust, the Fund, the Adviser, the Sub-Adviser or any affiliates thereof and is not involved with this offering in any way, and has no obligation to consider the Fund in taking any actions that might affect the value of the Fund. The Trust, the Fund, the Adviser, the Sub-Adviser or any affiliate are not responsible for the performance of the Treasury Bond ETF and make no representation as to the performance of the Treasury Bond ETF. Investing in the Fund is not equivalent to investing in the Treasury Bond ETF Fund shareholders will not have voting rights or rights to receive dividends or other distributions or any other rights with respect to the Treasury Bond ETF.

 

UNITED STATES RISK. Certain changes in the U.S. economy, such as when the U.S. economy weakens or when its financial markets decline, may have an adverse effect on the securities to which the Fund has exposure.

 

U.S. TREASURY OBLIGATIONS RISK. U.S. Treasury obligations may differ from other securities in their interest rates, maturities, times of issuance and other characteristics and may provide relatively lower returns than those of other securities. Changes in the U.S. government’s financial condition or credit rating may cause the value of U.S. Treasury obligations to decline. Direct obligations of the U.S. Treasury have historically involved little risk of loss of principal if held to maturity, but the market value of such securities is not guaranteed and may fluctuate. Although U.S. Treasury obligations are backed by the full faith and credit of the United States, circumstances could arise that could prevent the timely payment of interest or principal.

NON-DIVERSIFICATION RISK. As a “non-diversified” fund, the Fund may hold a smaller number of portfolio securities than many other funds. To the extent the Fund invests in a relatively small number of issuers, a decline in the market value of a particular security held by the Fund may affect its value more than if it invested in a larger number of issuers. The value of the Fund Shares may be more volatile than the values of shares of more diversified funds.

Roundhill Gold Miners WeeklyPay™ ETF | MARKET RISK  
Prospectus [Line Items]  
Risk [Text Block]

MARKET RISK. Market risk is the risk that a particular investment, or Fund Shares in general, may fall in value. Securities are subject to market fluctuations caused by real or perceived adverse economic, political, and regulatory factors or market developments, changes in interest rates, disruptions to trade, impositions of tariffs and perceived trends in securities prices. Fund Shares could decline in value or underperform other investments. In addition, local, regional or global events such as war, acts of terrorism, market manipulation, government defaults, government shutdowns, regulatory actions, political changes, diplomatic developments, the imposition of sanctions and other similar measures, spread of infectious diseases or other public health issues, recessions, natural disasters, or other events could have a significant negative impact on the Fund and its investments. Any of such circumstances could have a materially negative impact on the value of Fund Shares, the liquidity of an investment, and may result in increased market volatility. During any such events, Fund Shares may trade at increased premiums or discounts to their net asset value, the bid/ask spread on Fund Shares may widen and the returns on investment may fluctuate.

Roundhill Gold Miners WeeklyPay™ ETF | LIQUIDITY RISK  
Prospectus [Line Items]  
Risk [Text Block]

LIQUIDITY RISK. The market for swap agreements that reference the Gold Miners ETF shares may be subject to periods of illiquidity. During such times it may be difficult or impossible to buy or sell a position at the desired price. Market disruptions or volatility can also make it difficult to find a counterparty willing to transact at a reasonable price and sufficient size. Illiquid markets may cause losses, which could be significant. The large size of the positions which the Fund may acquire increases the risk of illiquidity, may make its positions more difficult to liquidate, and may increase the losses incurred while trying to do so. Such large positions also may impact the price of swap agreements on the Gold Miners ETF shares.

Roundhill Gold Miners WeeklyPay™ ETF | ACTIVE MANAGEMENT RISK  
Prospectus [Line Items]  
Risk [Text Block]

ACTIVE MANAGEMENT RISK. The Fund is actively-managed and its performance reflects investment decisions that the Adviser and/or Sub-Adviser makes for the Fund. Such judgments about the Fund’s investments may prove to be incorrect. If the investments selected and the strategies employed by the Fund fail to produce the intended results, the Fund could underperform as compared to other funds with similar investment objectives and/or strategies, or could have negative returns.

Roundhill Gold Miners WeeklyPay™ ETF | ACTIVE MARKET RISK

ACTIVE MARKET RISK. Although Fund Shares are listed for trading on the Exchange, there can be no assurance that an active trading market for Fund Shares will develop or be maintained. Fund Shares trade on the Exchange at market prices that may be below, at or above the Fund’s net asset value. Securities, including Fund Shares, are subject to market fluctuations and liquidity constraints that may be caused by such factors as economic, political, or regulatory developments, changes in interest rates, and/or perceived trends in securities prices. Fund Shares could decline in value or underperform other investments.

CONCENTRATION RISK. The Fund is susceptible to an increased risk of loss, including losses due to adverse events that affect the Fund’s investments more than the market as a whole, to the extent that the Fund’s investments are concentrated in investments that provide exposure to the Gold Miners ETF and the industry or group of industries to which it is concentrated.

Roundhill Gold Miners WeeklyPay™ ETF | COUNTERPARTY RISK

Risk [Text Block]

COUNTERPARTY RISK. Fund transactions involving a counterparty are subject to the risk that the counterparty will not fulfill its obligation to the Fund. Counterparty risk may arise because of the counterparty’s financial condition (i.e., financial difficulties, bankruptcy, or insolvency), market activities and developments, or other reasons, whether foreseen or not. A counterparty’s inability to fulfill its obligation may result in significant financial loss to the Fund. The Fund may be unable to recover its investment from the counterparty or may obtain a limited recovery, and/or recovery may be delayed.

Roundhill Gold Miners WeeklyPay™ ETF | CURRENT MARKET CONDITIONS RISK  
Prospectus [Line Items]  
Risk [Text Block]

CURRENT MARKET CONDITIONS RISK. Current market conditions risk is the risk that a particular investment, or Fund Shares in general, may fall in value due to current market conditions. As a means to fight inflation, which remains at elevated levels, the Federal Reserve and certain foreign central banks have raised interest rates; however, the Federal Reserve has recently lowered interest rates and may continue to do so. U.S. regulators have proposed several changes to market and issuer regulations which would directly impact the Fund, and any regulatory changes could adversely impact the Fund’s ability to achieve its investment strategies or make certain investments. Recent and potential future bank failures could result in disruption to the broader banking industry or markets generally and reduce confidence in financial institutions and the economy as a whole, which may also heighten market volatility and reduce liquidity. Additionally, challenges in commercial real estate markets, including rising interest rates, declining valuations and increasing vacancies, could have a broader impact on financial markets. The ongoing adversarial political climate in the United States, as well as political and diplomatic events both domestic and abroad, have and may continue to have an adverse impact the U.S. regulatory landscape, markets and investor behavior, which could have a negative impact on the Fund’s investments and operations. The change in administration resulting from the 2024 United States national elections could result in significant impacts to international trade relations, tax and immigration policies, and other aspects of the national and international political and financial landscape, which could affect, among other things, inflation and the securities markets generally. Other unexpected political, regulatory and diplomatic events within the U.S. and abroad may affect investor and consumer confidence and may adversely impact financial markets and the broader economy. For example, ongoing armed conflicts between Russia and Ukraine in Europe and among Israel, Iran, Hamas and other militant groups in the Middle East, have caused and could continue to cause significant market disruptions and volatility within the markets in Russia, Europe, the Middle East and the United States. The hostilities and sanctions resulting from those hostilities have and could continue to have a significant impact on certain Fund investments as well as Fund performance and liquidity. The economies of the United States and its trading partners, as well as the financial markets generally, may be adversely impacted by trade disputes, including the imposition of tariffs, and other matters. For example, the United States has imposed trade barriers and restrictions on China. In addition, the Chinese government is engaged in a longstanding dispute with Taiwan, continually threatening an invasion. If the political climate between the United States and China does not improve or continues to deteriorate, if China were to attempt invading Taiwan, or if other geopolitical conflicts develop or worsen, economies, markets and individual securities may be adversely affected, and the value of the Fund’s assets may go down. A public health crisis and the ensuing policies enacted by governments and central banks may cause significant volatility and uncertainty in global financial markets, negatively impacting global growth prospects. As the COVID-19 global pandemic illustrated, such events may affect certain geographic regions, countries, sectors and industries more significantly than others. Advancements in technology may also adversely impact markets and the overall performance of the Fund. For instance, the economy may be significantly impacted by the advanced development and increased regulation of artificial intelligence. Additionally, cyber security breaches of both government and non-government entities could have negative impacts on infrastructure and the ability of such entities, including the Fund, to operate properly. These events, and any other future events, may adversely affect the prices and liquidity of the Fund’s portfolio investments and could result in disruptions in the trading markets.

Roundhill Gold Miners WeeklyPay™ ETF | CYBERSECURITY RISK  
Prospectus [Line Items]  
Risk [Text Block]

CYBERSECURITY RISK. Failures or breaches of the electronic systems of the Fund, the Fund’s adviser, sub-adviser, distributor and other service providers, market makers, Authorized Participants or the issuers of securities in which the Fund invests have the ability to cause disruptions, negatively impact the Fund’s business operations and/or potentially result in financial losses to the Fund and its shareholders. While the Fund has established business continuity plans and risk management systems seeking to address system breaches or failures, there are inherent limitations in such plans and systems. Furthermore, the Fund cannot control the cybersecurity plans and systems of the Fund’s other service providers, market makers, Authorized Participants or issuers of securities in which the Fund invests.

Roundhill Gold Miners WeeklyPay™ ETF | DEBT SECURITIES RISK  
Prospectus [Line Items]  
Risk [Text Block]

DEBT SECURITIES RISK. Investments in debt securities subject the holder to the credit risk of the issuer. Credit risk refers to the possibility that the issuer or other obligor of a security will not be able or willing to make payments of interest and principal when due. Generally, the value of debt securities will change inversely with changes in interest rates. To the extent that interest rates rise, certain underlying obligations may be paid off substantially slower than originally anticipated and the value of those securities may fall sharply. During periods of falling interest rates, the income received by the Fund may decline. If the principal on a debt security is prepaid before expected, the prepayments of principal may have to be reinvested in obligations paying interest at lower rates. Debt securities generally do not trade on a securities exchange making them generally less liquid and more difficult to value than common stock.

Roundhill Gold Miners WeeklyPay™ ETF | DERIVATIVES RISK  
Prospectus [Line Items]  
Risk [Text Block]

DERIVATIVES RISK. The use of derivative instruments involves risks different from, or possibly greater than, the risks associated with investing directly in securities and other traditional investments. These risks include: (i) the risk that the counterparty to a derivative transaction may not fulfill its contractual obligations; (ii) risk of mispricing or improper valuation; and (iii) the risk that changes in the value of the derivative may not correlate perfectly with the underlying asset. Derivative prices are highly volatile and may fluctuate substantially during a short period of time. Such prices are influenced by numerous factors that affect the markets, including, but not limited to: changing supply and demand relationships; government programs and policies; national and international political and economic events, changes in interest rates, inflation and deflation and changes in supply and demand relationships. Trading derivative instruments involves risks different from, or possibly greater than, the risks associated with investing directly in securities. Derivative contracts ordinarily have leverage inherent in their terms. The use of leverage may cause the Fund to liquidate portfolio positions when it would not be advantageous to do so in order to satisfy its obligations or to meet regulatory or contractual requirements for derivatives. The use of derivatives can magnify potential for gain or loss and, therefore, amplify the effects of market volatility on share price.

Roundhill Gold Miners WeeklyPay™ ETF | DISTRIBUTION TAX RISK  
Prospectus [Line Items]  
Risk [Text Block]

DISTRIBUTION TAX RISK. The Fund currently expects to make distributions on a weekly basis. Such frequent distributions may expose investors to increased tax liabilities. However, these distributions may exceed the Fund’s income and gains for the Fund’s taxable year. Distributions in excess of the Fund’s current and accumulated earnings and profits will be treated as a return of capital. A return of capital distribution generally will not be taxable but will reduce the shareholder’s cost basis and will result in a higher capital gain or lower capital loss when those Fund Shares on which the distribution was received are sold. Once a Fund shareholder’s cost basis is reduced to zero, further distributions will be treated as capital gain if the Fund shareholder holds Fund Shares as capital assets. Additionally, any capital returned through distributions will be distributed after payment of Fund fees and expenses. Because a portion of the Fund’s distributions may consist of return of capital, the Fund may not be an appropriate investment for investors who do not want their principal investment in the Fund to decrease over time or who do not wish to receive return of capital in a given period. In the event that a shareholder purchases Fund Shares shortly before a distribution by the Fund, the entire distribution may be taxable to the shareholder even though a portion of the distribution effectively represents a return of the purchase price.

Roundhill Gold Miners WeeklyPay™ ETF | ETF RISK  
Prospectus [Line Items]  
Risk [Text Block]

ETF RISK. The Fund may invest in ETFs. The value of an ETF held by the Fund will fluctuate over time based on fluctuations in the values of the assets held by the ETF, which may be affected by changes in general economic conditions, expectations for future growth and profits, interest rates and the supply and demand for those assets. When the Fund invests in an ETF, it will bear a proportionate share of the ETF’s expenses. Brokerage, tax and other expenses may negatively impact the performance of the ETF and, in turn, the value of the Fund Shares. An ETF that tracks an index may not exactly match the performance of the index due to cash drag, differences between the portfolio of the ETF and the components of the index, expenses and other factors.

Roundhill Gold Miners WeeklyPay™ ETF | INFLATION RISK  
Prospectus [Line Items]  
Risk [Text Block]

INFLATION RISK. Inflation risk is the risk that the value of assets or income from investments will be less in the future as inflation decreases the value of money. As inflation increases, the present value of the Fund’s assets and distributions may decline. This risk is more prevalent with respect to fixed income securities held by the Fund.

Roundhill Gold Miners WeeklyPay™ ETF | Interest Rate Risk [Member]  
Prospectus [Line Items]  
Risk [Text Block]

INTEREST RATE RISK. Interest rate risk is the risk that the value of the debt securities in the Fund’s portfolio will decline because of rising market interest rates. Interest rate risk is generally lower for shorter term debt securities and higher for longer-term debt securities. Duration is a reasonably accurate measure of a debt security’s price sensitivity to changes in interest rates and a common measure of interest rate risk. Duration measures a debt security’s expected life on a present value basis, taking into account the debt security’s yield, interest payments and final maturity. In general, duration represents the expected percentage change in the value of a security for an immediate 1% change in interest rates. For example, the price of a debt security with a three-year duration would be expected to drop by approximately 3% in response to a 1% increase in interest rates. Therefore, prices of debt securities with shorter durations tend to be less sensitive to interest rate changes than debt securities with longer durations. As the value of a debt security changes over time, so will its duration.

Roundhill Gold Miners WeeklyPay™ ETF | LEGISLATION AND LITIGATION RISK  
Prospectus [Line Items]  
Risk [Text Block]

LEGISLATION AND LITIGATION RISK. Legislation or litigation that affects the value of assets or securities held by the Fund may reduce the value of the Fund. From time to time, various legislative initiatives are proposed that may have a negative impact on certain assets or securities in which the Fund invests. In addition, litigation regarding any of the assets or securities owned by the Fund may negatively impact the value of the Shares. Such legislation or litigation may cause the Fund to lose value or may result in higher portfolio turnover if the Adviser determines to sell such a holding.

Roundhill Gold Miners WeeklyPay™ ETF | LEVERAGE RISK  
Prospectus [Line Items]  
Risk [Text Block]

LEVERAGE RISK. The Fund obtains investment exposure in excess of its net assets by utilizing leverage and may lose more money in market conditions that are adverse to its investment objectives than a fund that does not utilize leverage. An investment in the Fund is exposed to the risk that a decline in the weekly performance of shares of the Gold Miners ETF will be magnified. This means that an investment in the Fund will be reduced by an amount equal to 1.2% for every 1% weekly decline in the market value of the Gold Miners ETF shares, not including the costs of financing leverage and other operating expenses, which would further reduce its value. The Fund could theoretically lose an amount greater than its net assets in the event the market value of the Gold Miners ETF shares decline more than 83.33% over a calendar week. Leverage will also have the effect of magnifying any differences in the Fund’s correlation with the Gold Miners ETF shares.

Roundhill Gold Miners WeeklyPay™ ETF | MONEY MARKET INSTRUMENTS RISK  
Prospectus [Line Items]  
Risk [Text Block]

MONEY MARKET INSTRUMENTS RISK. The value of money market instruments may be affected by changing interest rates and by changes in the credit ratings of the investments. If a significant amount of the Fund’s assets are invested in money market instruments, it will be more difficult for the Fund to achieve its investment objectives. An investment in a money market fund is not insured or guaranteed by the FDIC or any other government agency. It is possible to lose money by investing in a money market fund.

Roundhill Gold Miners WeeklyPay™ ETF | OPERATIONAL RISK  
Prospectus [Line Items]  
Risk [Text Block]

OPERATIONAL RISK. The Fund is subject to risks arising from various operational factors, including, but not limited to, human error, processing and communication errors, errors of the Fund’s service providers, counterparties or other third-parties, failed or inadequate processes and technology or systems failures. The Fund relies on third-parties for a range of services, including custody. Any delay or failure relating to engaging or maintaining such service providers may affect the Fund’s ability to meet its investment objectives. Although the Fund and the Adviser seek to reduce these operational risks through controls and procedures, there is no way to completely protect against such risks.

Roundhill Gold Miners WeeklyPay™ ETF | SPECIAL TAX RISK  
Prospectus [Line Items]  
Risk [Text Block]

SPECIAL TAX RISK. The Fund intends to qualify annually and to elect to be treated as a regulated investment company under the Internal Revenue Code of 1986, as amended (the “Code”). To qualify for the favorable U.S. federal income tax treatment generally accorded to regulated investment companies, the Fund must, among other things, (i) derive in each taxable year at least 90% of its gross income from dividends, interest, payments with respect to securities loans and gains from the sale or other disposition of stock, securities or foreign currencies or other income derived with respect to its business of investing in such stock, securities or currencies, or net income derived from interests in certain publicly traded partnerships; (ii) diversify its holdings so that, at the end of each quarter of the taxable year, (a) at least 50% of the market value of the Fund’s assets is represented by cash and cash items (including receivables), U.S. government securities, the securities of other regulated investment companies and other securities, with such other securities of any one issuer generally limited for the purposes of this calculation to an amount not greater than 5% of the value of the Fund’s total assets and not greater than 10% of the outstanding voting securities of such issuer, and (b) not more than 25% of the value of its total assets is invested in the securities (other than U.S. government securities or the securities of other regulated investment companies) of any one issuer, or two or more issuers which the Fund controls which are engaged in the same, similar or related trades or businesses, or the securities of one or more of certain publicly traded partnerships; and (iii) distribute at least 90% of its investment company taxable income (which includes, among other items, dividends, interest and net short-term capital gains in excess of net long-term capital losses) and at least 90% of its net tax-exempt interest income each taxable year. There are certain exceptions for failure to qualify if the failure is for reasonable cause or is de minimis, and certain corrective action is taken and certain tax payments are made by the Fund.

 

The authority with regard to swaps entered into by regulated investment companies is unclear both as to the qualification under the income test and the identification of the issuer under the diversification test. The Fund intends to take the position that because the swaps held by the Fund reference securities that the income on the swaps are “other income” from the Fund’s business of investing in stocks and securities. In addition, the Fund intends to manage its investments in the swaps so that neither the exposure to issuer of the referenced security nor the exposure to any one counterparty of the swaps will exceed 25% of the gross value of the Fund’s portfolio at the end of any quarter.

 

If the Fund were to fail to meet the qualifying income test or asset diversification test and fail to qualify as a RIC, it would be taxed in the same manner as an ordinary corporation, and distributions to its shareholders would not be deductible by the Fund in computing its taxable income, which would adversely affect the Fund’s performance.

Roundhill Gold Miners WeeklyPay™ ETF | STRUCTURAL ETF RISKS  
Prospectus [Line Items]  
Risk [Text Block]

STRUCTURAL ETF RISKS. The Fund is an ETF. Accordingly, it is subject to certain risks associated with its unique structure.

 

Market Participants Risk. Only an Authorized Participant may engage in creation or redemption transactions directly with the Fund, and none of those Authorized Participants is obligated to engage in creation and/or redemption transactions. The Fund has a limited number of institutions that may act as Authorized Participants on an agency basis (i.e., on behalf of other market participants). To the extent that Authorized Participants exit the business or are unable to proceed with creation or redemption orders with respect to the Fund and no other Authorized Participant is able to step forward to create or redeem, Fund Shares may be more likely to trade at a premium or discount to NAV and possibly face trading halts or delisting. The Fund may also rely on a small number of third-party market makers to provide a market for the purchase and sale of Fund Shares but such market makers are under no obligation to do so. Decisions by Authorized Participants or market makers to reduce their role or step away from these activities in times of market stress could inhibit the effectiveness of the arbitrage process in maintaining the relationship between the underlying values of the Fund’s portfolio securities and the Fund’s market price. Any trading halt or other problem relating to the trading activity of these market makers or any issues disrupting the Authorized Participants’ ability to proceed with creation and/or redemption orders could result in a dramatic change in the spread between the Fund’s net asset value and the price at which Fund Shares are trading on the Exchange, which could result in a decrease in value of Fund Shares. This reduced effectiveness could result in Fund Shares trading at a premium or discount to net asset value and also in greater than normal intraday bid-ask spreads Fund Shares.

 

Cash Transactions Risk. The Fund currently expects to effect a significant portion of its creations and redemptions for cash, rather than in-kind securities. Paying redemption proceeds in cash rather than through in-kind delivery of portfolio securities may require the Fund to dispose of or sell portfolio securities or other assets at an inopportune time to obtain the cash needed to meet redemption orders. This may cause the Fund to sell a security and recognize a capital gain or loss that might not have been incurred if it had made a redemption in-kind. As a result, the Fund may pay out higher or lower annual capital gains distributions than ETFs that redeem in-kind. The use of cash creations and redemptions may also cause the Fund’s Shares to trade in the market at greater bid-ask spreads or greater premiums or discounts to the Fund’s NAV. Furthermore, the Fund may not be able to execute cash transactions for creation and redemption purposes at the same price used to determine the Fund’s NAV. To the extent that the maximum additional charge for creation or redemption transactions is insufficient to cover the execution shortfall, the Fund’s performance could be negatively impacted.

 

Costs of Buying and Selling Fund Shares. Due to the costs of buying or selling Fund Shares, including brokerage commissions imposed by brokers and bid/ask spreads, frequent trading of Fund Shares may significantly reduce investment results and an investment in Fund Shares may not be advisable for investors who anticipate regularly making small investments.

 

Premium/Discount Risk. As with all ETFs, Fund Shares may be bought and sold in the secondary market at market prices. The trading prices of Fund Shares in the secondary market may differ from the Fund’s daily net asset value per share and there may be times when the market price of the shares is more than the net asset value per share (premium) or less than the net asset value per share (discount). If a shareholder purchases Fund Shares at a time when the market price is at a premium to the net asset value or sells Fund Shares at a time when the market price is at a discount to the net asset value, the shareholder may pay more for, or receive less than, the underlying value of the Fund Shares, respectively. This risk is heightened in times of market volatility or periods of steep market declines.

 

Trading Risks. Although Fund Shares are listed for trading on the Exchange and may be traded on U.S. exchanges other than the Exchange, there can be no assurance that Fund Shares will trade with any volume, or at all, on any stock exchange. In stressed market conditions, the liquidity of Fund Shares may begin to mirror the liquidity of the Fund’s underlying portfolio holdings, which can be significantly less liquid than Fund Shares. Trading in Fund Shares on the Exchange may be halted due to market conditions or for reasons that, in the view of the Exchange, make trading in Fund Shares inadvisable. In addition, trading in Fund Shares on the Exchange is subject to trading halts caused by extraordinary market volatility pursuant to the Exchange’s “circuit breaker” rules. There can be no assurance that the requirements of the Exchange necessary to maintain the listing of the Fund will continue to be met or will remain unchanged.

Roundhill Gold Miners WeeklyPay™ ETF | U.S. GOVERNMENT SECURITIES RISK  
Prospectus [Line Items]  
Risk [Text Block]

U.S. GOVERNMENT SECURITIES RISK. U.S. government securities are subject to interest rate risk but generally do not involve the credit risks associated with investments in other types of debt securities. As a result, the yields available from U.S. government securities are generally lower than the yields available from other debt securities. U.S. government securities are guaranteed only as to the timely payment of interest and the payment of principal when held to maturity.

Roundhill Gold Miners WeeklyPay™ ETF | VALUATION RISK  
Prospectus [Line Items]  
Risk [Text Block]

VALUATION RISK. The Fund may hold securities or other assets that may be valued on the basis of factors other than market quotations. This may occur because the asset or security does not trade on a centralized exchange, or in times of market turmoil or reduced liquidity. There are multiple methods that can be used to value a portfolio holding when market quotations are not readily available. The value established for any portfolio holding at a point in time might differ from what would be produced using a different methodology or if it had been priced using market quotations. Portfolio holdings that are valued using techniques other than market quotations, including “fair valued” assets or securities, may be subject to greater fluctuation in their valuations from one day to the next than if market quotations were used. In addition, there is no assurance that the Fund could sell or close out a portfolio position for the value established for it at any time, and it is possible that the Fund would incur a loss because a portfolio position is sold or closed out at a discount to the valuation established by the Fund at that time. The Fund’s ability to value investments may be impacted by technological issues or errors by pricing services or other third-party service providers.

Roundhill Gold Miners WeeklyPay™ ETF | EQUITY SECURITIES RISK  
Prospectus [Line Items]  
Risk [Text Block]

EQUITY SECURITIES RISK. Equity securities are subject to changes in value, and their values may be more volatile than those of other asset classes. Equity securities prices fluctuate for several reasons, including changes in investors’ perceptions of the financial condition of an issuer or the general condition of the relevant equity market, such as market volatility, or when political or economic events affecting an issuer occur. Common stock prices may be particularly sensitive to rising interest rates, as the cost of capital rises and borrowing costs increase. Common stocks generally subject their holders to more risks than preferred stocks and debt securities because common stockholders’ claims are subordinated to those of holders of preferred stocks and debt securities upon the bankruptcy of the issuer.

Roundhill Gold Miners WeeklyPay™ ETF | SWAP AGREEMENTS RISK  
Prospectus [Line Items]  
Risk [Text Block]

SWAP AGREEMENTS RISK. The Fund will utilize swap agreements to derive its exposure to shares of the Gold Miners ETF. Swap agreements may involve greater risks than direct investment in securities as they may be leveraged and are subject to credit risk, counterparty risk and valuation risk. A swap agreement could result in losses if the underlying reference or asset does not perform as anticipated. In addition, many swaps trade over-the-counter and may be considered illiquid. It may not be possible for the Fund to liquidate a swap position at an advantageous time or price, which may result in significant losses.

Roundhill Gold Miners WeeklyPay™ ETF | REGULATED INVESTMENT COMPANY TAX RISKS  
Prospectus [Line Items]  
Risk [Text Block]

REGULATED INVESTMENT COMPANY TAX RISKS. The Fund intends to qualify annually and to elect to be treated as a regulated investment company under the Internal Revenue Code of 1986, as amended (the “Code”). To qualify for the favorable U.S. federal income tax treatment generally accorded to regulated investment companies, the Fund must, among other things, (i) derive in each taxable year at least 90% of its gross income from dividends, interest, payments with respect to securities loans and gains from the sale or other disposition of stock, securities or foreign currencies or other income derived with respect to its business of investing in such stock, securities or currencies, or net income derived from interests in certain publicly traded partnerships; (ii) diversify its holdings so that, at the end of each quarter of the taxable year, (a) at least 50% of the market value of the Fund’s assets is represented by cash and cash items (including receivables), U.S. government securities, the securities of other regulated investment companies and other securities, with such other securities of any one issuer generally limited for the purposes of this calculation to an amount not greater than 5% of the value of the Fund’s total assets and not greater than 10% of the outstanding voting securities of such issuer, and (b) not more than 25% of the value of its total assets is invested in the securities (other than U.S. government securities or the securities of other regulated investment companies) of any one issuer, or two or more issuers which the Fund controls which are engaged in the same, similar or related trades or businesses, or the securities of one or more of certain publicly traded partnerships; and (iii) distribute at least 90% of its investment company taxable income (which includes, among other items, dividends, interest and net short-term capital gains in excess of net long-term capital losses) and at least 90% of its net tax-exempt interest income each taxable year. There are certain exceptions for failure to qualify if the failure is for reasonable cause or is de minimis, and certain corrective action is taken and certain tax payments are made by the Fund.

 

If the Fund were to fail to meet the qualifying income test or asset diversification test and fail to qualify as a RIC, it would be taxed in the same manner as an ordinary corporation, and distributions to its shareholders would not be deductible by the Fund in computing its taxable income, which would adversely affect the Fund’s performance.

Roundhill Gold Miners WeeklyPay™ ETF | LARGE SHAREHOLDER RISK  
Prospectus [Line Items]  
Risk [Text Block]

LARGE SHAREHOLDER RISK. Certain shareholders, including affiliated funds advised by the Adviser, may from time to time own a significant portion of the Fund’s shares. In addition, a third-party investor, the Adviser or an affiliate of the Adviser (“Affiliate”), an authorized participant, a market maker, or another entity may invest in the Fund and hold its investment for a limited period solely to facilitate the commencement of the Fund or to help the Fund achieve a specified size or scale. There can be no assurance that any large shareholder will not redeem its investment, that the size of the Fund will be maintained at such levels, or that the Fund will continue to meet applicable listing requirements. Redemptions by large shareholders could have a significant negative impact on the Fund. In addition, transactions by large shareholders may account for a large percentage of the trading volume on the Fund’s listing exchange and may, therefore, have a material upward or downward effect on the market price of the shares.

 

To the extent that a significant percentage of the Fund’s shares are owned or controlled by a small number of account shareholders (or a single account shareholder), including funds or accounts over which the Adviser or an Affiliate has investment discretion, the Fund is subject to the risk that those shareholders may purchase or redeem Fund shares in significant amounts rapidly or unexpectedly, including as a result of an asset allocation decision made by the Adviser or an Affiliate. This may adversely affect the Fund’s performance if the Adviser is forced to sell portfolio securities or invest cash when it would not otherwise choose to do so. Redemptions of a large number of shares may affect the liquidity of the Fund’s portfolio, increase the Fund’s transaction costs, and accelerate the realization of taxable income and/or gains. In addition, a large redemption could result in the Fund’s current expenses being allocated over a smaller asset base, leading to an increase in the Fund’s gross expense ratio. Large purchases of the Fund’s shares may also adversely affect the Fund’s performance to the extent that the Fund is delayed in investing new cash or otherwise maintains a larger cash position than it ordinarily would, particularly if the Fund accepts cash for an order for the purchase of creation units of the Fund’s shares.

Roundhill Gold Miners WeeklyPay™ ETF | GOLD MINERS ETF INVESTING RISKS  
Prospectus [Line Items]  
Risk [Text Block]

GOLD MINERS ETF INVESTING RISKS. The Fund will have significant exposure to the Gold Miners ETF through its investments in shares of the Gold Miners ETF and swap agreements that utilize the Gold Miners ETF as the reference asset. Accordingly, the Fund will subject to the risks of the Gold Miners ETF, set forth below. In addition to these risks, the Gold Miners ETF is also subject to the following risks to which the Fund is also subject, which are described within the section entitled “Principal Risks”: Market Risk, Asset Class Risk, Concentration Risk, Current Market Conditions Risk, Cybersecurity Risk, Equity Securities Risk, Operational Risk and Structural ETF Risk.

 

CURRENCY RISK. Because the Gold Miners ETF’s NAV is determined in U.S. dollars, the NAV could decline if the currency of a non-U.S. market in which the Gold Miners ETF invests depreciates against the U.S. dollar or if there are delays or limits on the repatriation of foreign currency. Currency exchange rates can be very volatile and can change quickly and unpredictably. As a result, the Gold Miners ETF’s NAV may change quickly and without warning. In addition, the Gold Miners ETF may incur costs in connection with conversions between U.S. dollars and foreign currencies.

 

GOLD AND SILVER MINING COMPANIES RISK. The Gold Miners ETF invests in stocks and depositary receipts of U.S. and foreign companies that are involved in the gold mining and silver mining industries, which are considered speculative and are affected by a variety of factors. Competitive pressures may have a significant effect on the financial condition of gold mining and silver mining companies. Also, gold and silver mining companies are highly dependent on the price of gold bullion and silver bullion, respectively, but may also be adversely affected by a variety of worldwide economic, financial and political factors. The price of gold and silver may fluctuate substantially over short periods of time so the Gold Miners ETF’s share price may be more volatile than other types of investments. Fluctuation in the prices of gold and silver may be due to a number of factors, including changes in inflation, changes in currency exchange rates and changes in industrial and commercial demand for metals (including fabricator demand). Additionally, increased environmental or labor costs may depress the value of metal investments.

 

INDEX-RELATED RISK. The Gold Miners ETF Index Provider may rely on various sources of information to assess the criteria of components of the Gold Miners ETF Index, including information that may be based on assumptions and estimates. Neither the Gold Miners ETF nor its investment adviser offer assurances that the Gold Miners ETF Index Provider’s methodology or sources of information will provide an accurate assessment of included components or will result in the Gold Miners ETF meeting its investment objective. Errors in index data, index computations or the construction of the Gold Miners ETF Index in accordance with its methodology may occur, and the Gold Miners ETF Index Provider may not identify or correct them promptly or at all, which may have an adverse impact on the Gold Miners ETF and its shareholders. Unusual market conditions or other unforeseen circumstances (such as natural disasters, political unrest or war) may impact the Gold Miners ETF Index Provider or a third-party data provider and could cause the Gold Miners ETF Index Provider to postpone a scheduled rebalance. This could cause the Gold Miners ETF Index to vary from its normal or expected composition.

 

INDIRECT INVESTMENT RISK. The Gold Miners ETF is not affiliated with the Trust, the Fund, the Adviser, the Sub-Adviser or any affiliates thereof and is not involved with this offering in any way, and has no obligation to consider the Fund in taking any actions that might affect the value of the Fund. The Trust, the Fund, the Adviser, the Sub-Adviser or any affiliate are not responsible for the performance of the Gold Miners ETF and make no representation as to the performance of the Gold Miners ETF. Investing in the Fund is not equivalent to investing in the Gold Miners ETF Fund shareholders will not have voting rights or rights to receive dividends or other distributions or any other rights with respect to the Gold Miners ETF.

 

INVESTMENT AND REPATRIATION RESTRICTIONS RISK. The government in an emerging market country may restrict or control to varying degrees the ability of foreign investors to invest in securities of issuers located or operating in such emerging market countries. These restrictions and/or controls may at times limit or prevent foreign investment in securities of issuers located or operating in emerging market countries and may inhibit the Gold Miners ETF’s ability to meet its investment objective. In addition, the Gold Miners ETF may not be able to buy or sell securities or receive full value for such securities. Moreover, certain emerging market countries may require governmental approval or special licenses prior to investments by foreign investors and may limit the amount of investments by foreign investors in a particular industry and/or issuer; may limit such foreign investment to a certain class of securities of an issuer that may have less advantageous rights than the classes available for purchase by domiciliaries of such emerging market countries; and/or may impose additional taxes on foreign investors. A delay in obtaining a required government approval or a license would delay investments in those emerging market countries, and, as a result, the Gold Miners ETF may not be able to invest in certain securities while approval is pending. The government of certain emerging market countries may also withdraw or decline to renew a license that enables the Gold Miners ETF to invest in such country. These factors make investing in issuers located or operating in emerging market countries significantly riskier than investing in issuers located or operating in more developed countries, and any one of them could cause a decline in the NAV of the Gold Miners ETF.

 

Additionally, investments in issuers located in certain emerging market countries may be subject to a greater degree of risk associated with governmental approval in connection with the repatriation of investment income, capital or the proceeds of sales of securities by foreign investors. Moreover, there is the risk that if the balance of payments in an emerging market country declines, the government of such country may impose temporary restrictions on foreign capital remittances. Consequently, the Gold Miners ETF could be adversely affected by delays in, or a refusal to grant, required governmental approval for repatriation of capital, as well as by the application to the Gold Miners ETF of any restrictions on investments. Furthermore, investments in emerging market countries may require the Gold Miners ETF to adopt special procedures, seek local government approvals or take other actions, each of which may involve additional costs to the Gold Miners ETF.

 

LARGE CAPITALIZATION COMPANIES RISK. Large capitalization companies may be less able than smaller capitalization companies to adapt to changing market conditions. Large capitalization companies may be more mature and subject to more limited growth potential compared with smaller capitalization companies. During different market cycles, the performance of large capitalization companies has trailed the overall performance of the broader securities markets.

 

MID-CAPITALIZATION COMPANIES RISK. Compared to large capitalization companies, mid-capitalization companies may be less stable and more susceptible to adverse developments. The securities of mid-capitalization companies may be more volatile and less liquid than those of large-capitalization companies. As a result, the Gold Miners ETF’s share price may be more volatile than that of a fund with a greater investment in large-capitalization stocks.

 

NON-U.S. SECURITIES RISK. Securities issued by non-U.S. issuers (including depositary receipts) are subject to different legal, regulatory, political, economic, and market risks than securities issued by U.S. issuers. These risks include greater market volatility, less market liquidity, higher transaction costs, expropriation, confiscatory taxation, adverse changes in foreign investment or currency control regulations, restrictions on the repatriation of capital, and political instability. Non-U.S. issuers may be subject to different accounting, audit and financial reporting standards than U.S. issuers, and there may be less publicly available information about non-U.S. issuers. Foreign market trading hours, different clearing and settlement procedures, and holiday schedules may limit the Gold Miners ETF’s ability to engage in portfolio transactions. To the extent that investments are made in a limited number of countries, events in those countries will have a more significant impact on the Gold Miners ETF.

 

RISK OF INVESTING IN EMERGING MARKETS. Investments in emerging market issuers may be subject to a greater risk of loss than investments in issuers located or operating in more developed markets. Emerging markets may be more likely to experience inflation, social instability, political turmoil or rapid changes in economic conditions than more developed markets. Companies in many emerging markets are not subject to the same degree of regulatory requirements, accounting standards or auditor oversight as companies in more developed countries, and as a result, information about the securities in which the Gold Miners ETF invests may be less reliable or complete. Emerging markets often have less reliable securities valuations and greater risk associated with custody of securities than developed markets. There may be significant obstacles to obtaining information necessary for investigations into or litigation against companies and shareholders may have limited legal remedies. The Gold Miners ETF does not select investments based on investor protection considerations.

 

SMALL CAPITALIZATION COMPANIES RISK. Compared to mid- and large-capitalization companies, small-capitalization companies may be less stable and more susceptible to adverse developments. The securities of small-capitalization companies may be more volatile and less liquid than those of mid- and large-capitalization companies. As a result, the Gold Miners ETF’s share price may be more volatile than that of a fund with a greater investment in large- or mid-capitalization stocks.

 

SPECIAL RISK CONSIDERATIONS OF INVESTING IN AFRICAN ISSUERS. Investments in securities of African issuers, including issuers located outside of Africa that generate significant revenues from Africa, involve risks and special considerations not typically associated with investments in the U.S. securities markets. Such heightened risks include, among others, expropriation and/or nationalization of assets, restrictions on and government intervention in international trade, confiscatory taxation, political instability, including authoritarian and/or military involvement in governmental decision making, armed conflict, terrorism, infectious disease outbreaks, strained international relations related to border disputes, the impact on the economy as a result of civil war, and social instability as a result of religious, ethnic and/or socioeconomic unrest and, in certain countries, genocidal warfare. Unanticipated political or social developments may result in sudden and significant investment losses. Additionally, Africa is located in a part of the world that has historically been prone to natural disasters, such as droughts, and is economically sensitive to environmental events.

 

The securities markets in Africa are underdeveloped and are often considered to be less correlated to global economic cycles than those markets located in more developed countries or geographic regions. A subset of African emerging market countries are considered to be “frontier markets.” Frontier market countries generally have smaller economies and less developed capital markets than traditional emerging markets, and, as a result, the risks of investing in emerging market countries are magnified in frontier market countries. As a result, securities markets in Africa are subject to greater risks associated with market volatility, lower market capitalization, lower trading volume, illiquidity, inflation, greater price fluctuations, uncertainty regarding the existence of trading markets, governmental control and heavy regulation of labor and industry. There may also be a high concentration of trading volume in a small number of issuers, investors and financial intermediaries representing a limited number of sectors or industries. Moreover, trading on securities markets may be suspended altogether.

 

Certain economies in African countries depend to a significant degree upon exports of primary commodities such as agricultural products, gold, silver, copper, diamonds and oil. These economies therefore are vulnerable to changes in commodity prices, which in turn may be affected by a variety of factors.

 

Certain governments in Africa may restrict or control to varying degrees the ability of foreign investors to invest in securities of issuers located or operating in those countries. These restrictions and/or controls may at times limit or prevent foreign investment in securities of issuers located or operating in countries in Africa. Moreover, certain countries in Africa may require governmental approval or special licenses prior to investments by foreign investors and may limit the amount of investments by foreign investors in a particular industry and/or issuer and may limit such foreign investment to a certain class of securities of an issuer that may have less advantageous rights than the classes available for purchase by domiciliaries of those countries and/or impose additional taxes on foreign investors. These factors, among others, make investing in issuers located or operating in countries in Africa significantly riskier than investing in issuers located or operating in more developed countries, and any one of them could cause a decline in the value of the Gold Miners ETF’s shares.

 

There may be a risk of loss due to the imposition of restrictions on repatriation of capital invested. In addition, certain African countries have currencies pegged to the U.S. dollar. If such currency pegs are abandoned, such abandonment could cause sudden and significant currency adjustments, which could impact the Gold Miners ETF’s investment returns in those countries. There may be limitations or delays in the convertibility or repatriation of certain African currencies, which would adversely affect the U.S. dollar value and/or liquidity of the Gold Miners ETF’s investments denominated in such African currencies, may impair the Gold Miners ETF’s ability to achieve its investment objective and/or may impede the Gold Miners ETF’s ability to satisfy redemption requests in a timely manner. For these or other reasons, the Gold Miners ETF could seek to suspend redemptions of creation units, including in the event that an emergency exists in which it is not reasonably practicable for the Gold Miners ETF to dispose of its securities or to determine its NAV. The Gold Miners ETF could also, among other things, limit or suspend creations of creation units. During the period that creations or redemptions are affected, the Gold Miners ETF’s shares could trade at a significant premium or discount to their NAV. In the case of a period during which creations are suspended, the Gold Miners ETF could experience substantial redemptions, which may exacerbate the discount to NAV at which the Gold Miners ETF’s shares trade, cause the Gold Miners ETF to experience increased transaction costs, and cause the Gold Miners ETF to make greater taxable distributions to shareholders of the Gold Miners ETF. When the Gold Miners ETF holds illiquid investments, its portfolio may be harder to value.

 

SPECIAL RISK CONSIDERATIONS OF INVESTING IN AUSTRALIAN ISSUERS. Investments in securities of Australian issuers involve risks and special considerations not typically associated with investments in the U.S. securities markets. The Australian economy is heavily dependent on exports from the agricultural and mining sectors. As a result, the Australian economy is susceptible to fluctuations in the commodity markets. The Australian economy is also dependent on trading with key trading partners.

 

SPECIAL RISK CONSIDERATIONS OF INVESTING IN CANADIAN ISSUERS. Investments in securities of Canadian issuers, including issuers located outside of Canada that generate significant revenue from Canada, involve risks and special considerations not typically associated with investments in the U.S. securities markets. The Canadian economy is very dependent on the demand for, and supply and price of, natural resources. The Canadian market is relatively concentrated in issuers involved in the production and distribution of natural resources. Canada is a major producer of commodities such as forest products, metals, agricultural products, and energy related products like oil, gas, and hydroelectricity. Accordingly, a change in the supply and demand of these resources, both domestically and internationally, can have a significant effect on Canadian market performance. Canada is a top producer of zinc and uranium and a global source of many other natural resources, such as gold, nickel, aluminum, and lead. Conditions that weaken demand for such products worldwide could have a negative impact on the Canadian economy as a whole. Additionally, the Canadian economy is heavily dependent on relationships with certain key trading partners, including the United States, countries in the European Union and China. Because the United States is Canada’s largest trading partner and foreign investor, the Canadian economy is dependent on and may be significantly affected by the U.S. economy. Reduction in spending on Canadian products and services or changes in the U.S. economy may adversely impact the Canadian economy. Trade agreements may further increase Canada’s dependency on the U.S. economy, and uncertainty as to the future of such trade agreements may cause a decline in the value of the Gold Miners ETF’s shares. The imposition of additional tariffs by the U.S. may have implications for the trade arrangements between the U.S. and Canada, which could negatively affect the value of securities held by the Gold Miners ETF. Past periodic demands by the Province of Quebec for sovereignty have significantly affected equity valuations and foreign currency movements in the Canadian market and such demands may have this effect in the future. In addition, certain sectors of Canada’s economy may be subject to foreign ownership limitations. This may negatively impact the Gold Miners ETF’s ability to invest in Canadian issuers and to pursue its investment objective.

 

UNITED STATES RISK. Certain changes in the U.S. economy, such as when the U.S. economy weakens or when its financial markets decline, may have an adverse effect on the securities to which the Fund has exposure.

NON-DIVERSIFICATION RISK. As a “non-diversified” fund, the Fund may hold a smaller number of portfolio securities than many other funds. To the extent the Fund invests in a relatively small number of issuers, a decline in the market value of a particular security held by the Fund may affect its value more than if it invested in a larger number of issuers. The value of the Fund Shares may be more volatile than the values of shares of more diversified funds.

Roundhill Meme Stock Covered Call ETF | MARKET RISK  
Prospectus [Line Items]  
Risk [Text Block]

MARKET RISK. Market risk is the risk that a particular investment, or Fund Shares in general, may fall in value. Securities are subject to market fluctuations caused by real or perceived adverse economic, political, and regulatory factors or market developments, changes in interest rates, disruptions to trade, impositions of tariffs and perceived trends in securities prices. Fund Shares could decline in value or underperform other investments. In addition, local, regional or global events such as war, acts of terrorism, market manipulation, government defaults, government shutdowns, regulatory actions, political changes, diplomatic developments, the imposition of sanctions and other similar measures, spread of infectious diseases or other public health issues, recessions, natural disasters, or other events could have a significant negative impact on the Fund and its investments. Any of such circumstances could have a materially negative impact on the value of Fund Shares, the liquidity of an investment, and may result in increased market volatility. During any such events, Fund Shares may trade at increased premiums or discounts to their net asset value, the bid/ask spread on Fund Shares may widen and the returns on investment may fluctuate.

Roundhill Meme Stock Covered Call ETF | COVERED CALL STRATEGY RISK  
Prospectus [Line Items]  
Risk [Text Block]

COVERED CALL STRATEGY RISK. A covered call strategy involves writing (selling) covered call options in return for the receipt of premiums. The seller of the option gives up the opportunity to benefit from value increases in the Meme Stock ETF above the strike price of the sold call options, but continues to bear the risk of the Meme Stock ETF price declines. The premiums received from the options may not be sufficient to offset any losses sustained from Meme Stock ETF price declines. Exchanges may suspend the trading of options during periods of abnormal market volatility. Suspension of trading may mean that an option seller is unable to sell options at a time that may be desirable or advantageous to do so.

Roundhill Meme Stock Covered Call ETF | OPTIONS RISK  
Prospectus [Line Items]  
Risk [Text Block]

OPTIONS RISK. The use of options involves investment strategies and risks different from those associated with ordinary portfolio securities transactions and depends on the ability of the Fund’s portfolio managers to forecast market movements correctly. The prices of options are volatile and are influenced by, among other things, actual and anticipated changes in the value of the underlying instrument, or in interest or currency exchange rates, including the anticipated volatility, which in turn are affected by fiscal and monetary policies and by national and international political and economic events. The effective use of options also depends on the Fund’s ability to terminate option positions at times deemed desirable to do so. There is no assurance that the Fund will be able to effect closing transactions at any particular time or at an acceptable price. In addition, there may at times be an imperfect correlation between the movement in values of options and their underlying securities and there may at times not be a liquid secondary market for certain options. Lastly, the trading of options is subject to transaction costs that may impact the Fund’s returns.

Roundhill Meme Stock Covered Call ETF | LIQUIDITY RISK  
Prospectus [Line Items]  
Risk [Text Block]

LIQUIDITY RISK. The market for options may be subject to periods of illiquidity. During such times it may be difficult or impossible to buy or sell a position at the desired price. Market disruptions or volatility can also make it difficult to find a counterparty willing to transact at a reasonable price and sufficient size. Illiquid markets may cause losses, which could be significant. The large size of the positions which the Fund may acquire increases the risk of illiquidity, may make its positions more difficult to liquidate, and may increase the losses incurred while trying to do so. Such large positions also may impact the price of options held by the Fund.

Roundhill Meme Stock Covered Call ETF | ACTIVE MANAGEMENT RISK  
Prospectus [Line Items]  
Risk [Text Block]

ACTIVE MANAGEMENT RISK. The Fund is actively-managed and its performance reflects investment decisions that the Adviser and/or Sub-Adviser makes for the Fund. Such judgments about the Fund’s investments may prove to be incorrect. If the investments selected and the strategies employed by the Fund fail to produce the intended results, the Fund could underperform as compared to other funds with similar investment objectives and/or strategies, or could have negative returns. The Adviser/Sub-Adviser will seek to employ the Fund’s investment strategy regardless of whether there are periods of adverse market, economic, or other conditions and will not seek to take temporary defensive positions during such periods.

Roundhill Meme Stock Covered Call ETF | CLEARING MEMBER DEFAULT RISK  
Prospectus [Line Items]  
Risk [Text Block]

CLEARING MEMBER DEFAULT RISK. Transactions in some types of derivatives, including the options held by the Fund, are required to be centrally cleared (“cleared derivatives”). In a transaction involving cleared derivatives, the Fund’s counterparty is a clearinghouse, such as the OCC, rather than a bank or broker. Since the Fund is not a member of clearinghouses, and only members of a clearinghouse (“clearing members”) can participate directly in the clearinghouse, the Fund will hold cleared derivatives through accounts at clearing members. With regard its cleared derivatives positions, the Fund will make payments (including margin payments) to, and receive payments from, a clearinghouse through their accounts at clearing members. Customer funds held at a clearing organization in connection with any option contracts are held in a commingled omnibus account and are not identified to the name of the clearing member’s individual customers. As a result, assets deposited by the Fund with any clearing member as margin for its options position may, in certain circumstances, be used to satisfy losses of other clients of the Fund’s clearing member. In addition, although clearing members guarantee performance of their clients’ obligations to the clearinghouse, there is a risk that the assets of the Fund might not be fully protected in the event of the clearing member’s bankruptcy. The Fund is also subject to the risk that a limited number of clearing members are willing to transact on the Fund’s behalf, which heightens the risks associated with a clearing member’s default. If a clearing member defaults, the Fund could lose some or all of the benefits of a transaction entered into by the Fund with the clearing member. The loss of a clearing member for the Fund to transact with could result in increased transaction costs and other operational issues that could impede the Fund’s ability to implement its investment strategy. If the Fund cannot find a clearing member to transact with on the Fund’s behalf, the Fund may be unable to effectively implement its investment strategy.

Roundhill Meme Stock Covered Call ETF | CURRENT MARKET CONDITIONS RISK  
Prospectus [Line Items]  
Risk [Text Block]

CURRENT MARKET CONDITIONS RISK. Current market conditions risk is the risk that a particular investment, or Fund Shares in general, may fall in value due to current market conditions. As a means to fight inflation, which remains at elevated levels, the Federal Reserve and certain foreign central banks have raised interest rates; however, the Federal Reserve has recently lowered interest rates and may continue to do so. U.S. regulators have proposed several changes to market and issuer regulations which would directly impact the Fund, and any regulatory changes could adversely impact the Fund’s ability to achieve its investment strategies or make certain investments. Recent and potential future bank failures could result in disruption to the broader banking industry or markets generally and reduce confidence in financial institutions and the economy as a whole, which may also heighten market volatility and reduce liquidity. Additionally, challenges in commercial real estate markets, including rising interest rates, declining valuations and increasing vacancies, could have a broader impact on financial markets. The ongoing adversarial political climate in the United States, as well as political and diplomatic events both domestic and abroad, have and may continue to have an adverse impact the U.S. regulatory landscape, markets and investor behavior, which could have a negative impact on the Fund’s investments and operations. The change in administration resulting from the 2024 United States national elections could result in significant impacts to international trade relations, tax and immigration policies, and other aspects of the national and international political and financial landscape, which could affect, among other things, inflation and the securities markets generally. Other unexpected political, regulatory and diplomatic events within the U.S. and abroad may affect investor and consumer confidence and may adversely impact financial markets and the broader economy. For example, ongoing armed conflicts between Russia and Ukraine in Europe and among Israel, Iran, Hamas and other militant groups in the Middle East, have caused and could continue to cause significant market disruptions and volatility within the markets in Russia, Europe, the Middle East and the United States. The hostilities and sanctions resulting from those hostilities have and could continue to have a significant impact on certain Fund investments as well as Fund performance and liquidity. The economies of the United States and its trading partners, as well as the financial markets generally, may be adversely impacted by trade disputes, including the imposition of tariffs, and other matters. For example, the United States has imposed trade barriers and restrictions on China. In addition, the Chinese government is engaged in a longstanding dispute with Taiwan, continually threatening an invasion. If the political climate between the United States and China does not improve or continues to deteriorate, if China were to attempt invading Taiwan, or if other geopolitical conflicts develop or worsen, economies, markets and individual securities may be adversely affected and the value of the Fund’s assets may go down. A public health crisis and the ensuing policies enacted by governments and central banks may cause significant volatility and uncertainty in global financial markets, negatively impacting global growth prospects. As the COVID-19 global pandemic illustrated, such events may affect certain geographic regions, countries, sectors and industries more significantly than others. Advancements in technology may also adversely impact markets and the overall performance of the Fund. For instance, the economy may be significantly impacted by the advanced development and increased regulation of artificial intelligence. Additionally, cyber security breaches of both government and non-government entities could have negative impacts on infrastructure and the ability of such entities, including the Fund, to operate properly. These events, and any other future events, may adversely affect the prices and liquidity of the Fund’s portfolio investments and could result in disruptions in the trading markets.

CYBERSECURITY RISK. Failures or breaches of the electronic systems of the Fund, the Fund’s adviser, sub-adviser, distributor and other service providers, market makers, Authorized Participants or the issuers of securities in which the Fund invests have the ability to cause disruptions, negatively impact the Fund’s business operations and/or potentially result in financial losses to the Fund and its shareholders. While the Fund has established business continuity plans and risk management systems seeking to address system breaches or failures, there are inherent limitations in such plans and systems. Furthermore, the Fund cannot control the cybersecurity plans and systems of the Fund’s other service providers, market makers, Authorized Participants or issuers of securities in which the Fund invests.

Roundhill Meme Stock Covered Call ETF | DERIVATIVES RISK  
Prospectus [Line Items]  
Risk [Text Block]

DERIVATIVES RISK. The use of derivative instruments (i.e. options contracts) involves risks different from, or possibly greater than, the risks associated with investing directly in securities and other traditional investments. These risks include: (i) the risk that the counterparty to a derivative transaction may not fulfill its contractual obligations; (ii) risk of mispricing or improper valuation; and (iii) the risk that changes in the value of the derivative may not correlate perfectly with the underlying asset. Derivative prices are highly volatile and may fluctuate substantially during a short period of time. Such prices are influenced by numerous factors that affect the markets, including, but not limited to: changing supply and demand relationships; government programs and policies; national and international political and economic events, changes in interest rates, inflation and deflation and changes in supply and demand relationships. Trading derivative instruments involves risks different from, or possibly greater than, the risks associated with investing directly in securities. Derivative contracts ordinarily have leverage inherent in their terms. The use of leverage may cause the Fund to liquidate portfolio positions when it would not be advantageous to do so in order to satisfy its obligations or to meet regulatory or contractual requirements for derivatives. The use of derivatives can magnify potential for gain or loss and, therefore, amplify the effects of market volatility on the Fund Share price.

Roundhill Meme Stock Covered Call ETF | DISTRIBUTION TAX RISK  
Prospectus [Line Items]  
Risk [Text Block]

DISTRIBUTION TAX RISK. The Fund currently expects to make distributions on a weekly basis. These distributions may exceed the Fund’s income and gains for the Fund’s taxable year. Distributions in excess of the Fund’s current and accumulated earnings and profits will be treated as a return of capital. A return of capital distribution generally will not be taxable but will reduce the shareholder’s cost basis and will result in a higher capital gain or lower capital loss when those Fund Shares on which the distribution was received are sold. Once a Fund shareholder’s cost basis is reduced to zero, further distributions will be treated as capital gain if the Fund shareholder holds Fund Shares as capital assets. Additionally, any capital returned through distributions will be distributed after payment of Fund fees and expenses. Because a portion of the Fund’s distributions may consist of return of capital, the Fund may not be an appropriate investment for investors who do not want their principal investment in the Fund to decrease over time or who do not wish to receive return of capital in a given period. In the event that a shareholder purchases Fund Shares shortly before a distribution by the Fund, the entire distribution may be taxable to the shareholder even though a portion of the distribution effectively represents a return of the purchase price.

Roundhill Meme Stock Covered Call ETF | FLEX OPTIONS RISK  
Prospectus [Line Items]  
Risk [Text Block]

FLEX OPTIONS RISK. Trading FLEX Options involves risks different from, or possibly greater than, the risks associated with investing directly in securities. The Fund may experience losses from specific FLEX Option positions and certain FLEX Option positions may expire worthless. The FLEX Options are listed on an exchange; however, no one can guarantee that a liquid secondary trading market will exist for the FLEX Options. In the event that trading in the FLEX Options is limited or absent, the value of the Fund’s FLEX Options may decrease. In a less liquid market for the FLEX Options, liquidating the FLEX Options may require the payment of a premium (for written FLEX Options) or acceptance of a discounted price (for purchased FLEX Options) and may take longer to complete. A less liquid trading market may adversely impact the value of the FLEX Options and Fund shares and result in the Fund being unable to achieve its investment objectives. Less liquidity in the trading of the Fund’s FLEX Options could have an impact on the prices paid or received by the Fund for the FLEX Options in connection with creations and redemptions of the Fund’s shares. Depending on the nature of this impact to pricing, the Fund may be forced to pay more for redemptions (or receive less for creations) than the price at which it currently values the FLEX Options. Such overpayment or under collection could reduce the Fund’s ability to achieve its investment objectives. Additionally, in a less liquid market for the FLEX Options, the liquidation of a large number of options may more significantly impact the price. A less liquid trading market may adversely impact the value of the FLEX Options and the value of your investment. The trading in FLEX Options may be less deep and liquid than the market for certain other exchange-traded options, non-customized options or other securities.

Roundhill Meme Stock Covered Call ETF | INFLATION RISK

Risk [Text Block]

INFLATION RISK. Inflation risk is the risk that the value of assets or income from investments will be less in the future as inflation decreases the value of money. As inflation increases, the present value of the Fund’s assets and distributions may decline. This risk is more prevalent with respect to fixed income securities held by the Fund.

Roundhill Meme Stock Covered Call ETF | OPERATIONAL RISK

OPERATIONAL RISK. The Fund is subject to risks arising from various operational factors, including, but not limited to, human error, processing and communication errors, errors of the Fund’s service providers, counterparties or other third-parties, failed or inadequate processes and technology or systems failures. The Fund relies on third-parties for a range of services, including custody. Any delay or failure relating to engaging or maintaining such service providers may affect the Fund’s ability to meet its investment objectives. Although the Fund and the Adviser seek to reduce these operational risks through controls and procedures, there is no way to completely protect against such risks.

Roundhill Meme Stock Covered Call ETF | STRUCTURAL ETF RISKS  
Prospectus [Line Items]  
Risk [Text Block]

STRUCTURAL ETF RISKS. The Fund is an ETF. Accordingly, it is subject to certain risks associated with its unique structure.

 

Market Participants Risk. Only an Authorized Participant may engage in creation or redemption transactions directly with the Fund, and none of those Authorized Participants is obligated to engage in creation and/or redemption transactions. The Fund has a limited number of institutions that may act as Authorized Participants on an agency basis (i.e., on behalf of other market participants). To the extent that Authorized Participants exit the business or are unable to proceed with creation or redemption orders with respect to the Fund and no other Authorized Participant is able to step forward to create or redeem, Fund Shares may be more likely to trade at a premium or discount to NAV and possibly face trading halts or delisting. The Fund may also rely on a small number of third-party market makers to provide a market for the purchase and sale of Fund Shares but such market makers are under no obligation to do so. Decisions by Authorized Participants or market makers to reduce their role or step away from these activities in times of market stress could inhibit the effectiveness of the arbitrage process in maintaining the relationship between the underlying values of the Fund’s portfolio securities and the Fund’s market price. Any trading halt or other problem relating to the trading activity of these market makers or any issues disrupting the Authorized Participants’ ability to proceed with creation and/or redemption orders could result in a dramatic change in the spread between the Fund’s net asset value and the price at which Fund Shares are trading on the Exchange, which could result in a decrease in value of Fund Shares. This reduced effectiveness could result in Fund Shares trading at a premium or discount to net asset value and also in greater than normal intraday bid-ask spreads Fund Shares.

 

Cash Transactions Risk. The Fund may effect a significant portion of its creations and redemptions for cash, rather than in-kind securities. Paying redemption proceeds in cash rather than through in-kind delivery of portfolio securities may require the Fund to dispose of or sell portfolio securities or other assets at an inopportune time to obtain the cash needed to meet redemption orders. This may cause the Fund to sell a security and recognize a capital gain or loss that might not have been incurred if it had made a redemption in-kind. As a result, the Fund may pay out higher or lower annual capital gains distributions than ETFs that redeem in-kind. The use of cash creations and redemptions may also cause the Fund Shares to trade in the market at greater bid-ask spreads or greater premiums or discounts to the Fund’s NAV. Furthermore, the Fund may not be able to execute cash transactions for creation and redemption purposes at the same price used to determine the Fund’s NAV. To the extent that the maximum additional charge for creation or redemption transactions is insufficient to cover the execution shortfall, the Fund’s performance could be negatively impacted.

 

Active Market Risk. Although Fund Shares are listed for trading on the Exchange, there can be no assurance that an active trading market for Fund Shares will develop or be maintained. Fund Shares trade on the Exchange at market prices that may be below, at or above the Fund’s net asset value. Securities, including Fund Shares, are subject to market fluctuations and liquidity constraints that may be caused by such factors as economic, political, or regulatory developments, changes in interest rates, and/or perceived trends in securities prices. Fund Shares could decline in value or underperform other investments.

 

Costs of Buying and Selling Fund Shares. Due to the costs of buying or selling Fund Shares, including brokerage commissions imposed by brokers and bid/ask spreads, frequent trading of Fund Shares may significantly reduce investment results and an investment in Fund Shares may not be advisable for investors who anticipate regularly making small investments.

 

Premium/Discount Risk. As with all ETFs, Fund Shares may be bought and sold in the secondary market at market prices. The trading prices of Fund Shares in the secondary market may differ from the Fund’s daily net asset value per share and there may be times when the market price of the shares is more than the net asset value per share (premium) or less than the net asset value per share (discount). If a shareholder purchases Fund Shares at a time when the market price is at a premium to the net asset value or sells Fund Shares at a time when the market price is at a discount to the net asset value, the shareholder may pay more for, or receive less than, the underlying value of the Fund Shares, respectively. This risk is heightened in times of market volatility or periods of steep market declines.

 

Trading Risks. Although Fund Shares are listed for trading on the Exchange and may be traded on U.S. exchanges other than the Exchange, there can be no assurance that Fund Shares will trade with any volume, or at all, on any stock exchange. In stressed market conditions, the liquidity of Fund Shares may begin to mirror the liquidity of the Fund’s underlying portfolio holdings, which can be significantly less liquid than Fund Shares. Trading in Fund Shares on the Exchange may be halted due to market conditions or for reasons that, in the view of the Exchange, make trading in Fund Shares inadvisable. In addition, trading in Fund Shares on the Exchange is subject to trading halts caused by extraordinary market volatility pursuant to the Exchange’s “circuit breaker” rules. There can be no assurance that the requirements of the Exchange necessary to maintain the listing of the Fund will continue to be met or will remain unchanged.

Roundhill Meme Stock Covered Call ETF | VALUATION RISK  
Prospectus [Line Items]  
Risk [Text Block]

VALUATION RISK. The Fund may hold securities or other assets that may be valued on the basis of factors other than market quotations. This may occur because the asset or security does not trade on a centralized exchange, or in times of market turmoil or reduced liquidity. There are multiple methods that can be used to value a portfolio holding when market quotations are not readily available. The value established for any portfolio holding at a point in time might differ from what would be produced using a different methodology or if it had been priced using market quotations. Portfolio holdings that are valued using techniques other than market quotations, including “fair valued” assets or securities, may be subject to greater fluctuation in their valuations from one day to the next than if market quotations were used. In addition, there is no assurance that the Fund could sell or close out a portfolio position for the value established for it at any time, and it is possible that the Fund would incur a loss because a portfolio position is sold or closed out at a discount to the valuation established by the Fund at that time. The Fund’s ability to value investments may be impacted by technological issues or errors by pricing services or other third-party service providers.

Roundhill Meme Stock Covered Call ETF | NEW FUND RISK

NEW FUND RISK. The Fund is a recently organized investment company with a limited operating history. As a result, prospective investors have a limited track record or history on which to base their investment decision.

Roundhill Meme Stock Covered Call ETF | EARLY CLOSE/LATE CLOSE/TRADING HALT RISK  
Prospectus [Line Items]  
Risk [Text Block]

EARLY CLOSE/LATE CLOSE/TRADING HALT RISK. An exchange or market may close early, close late or issue trading halts on specific securities or financial instruments. As a result, the ability to trade certain securities or financial instruments may be restricted, which may disrupt the Fund’s creation and redemption process, potentially affect the price at which Fund Shares trade in the secondary market, and/or result in the Fund being unable to trade certain securities or financial instruments at all. In these circumstances, the Fund may be unable to rebalance its portfolio, may be unable to accurately price its investments and/or may incur substantial trading losses. If trading in Fund Shares are halted, investors may be temporarily unable to trade Fund Shares.

Roundhill Meme Stock Covered Call ETF | MEME STOCK ETF RISKS  
Prospectus [Line Items]  
Risk [Text Block]

MEME STOCK ETF RISKS. The Fund will have significant exposure to the Meme Stock ETF through its investments in shares of the Meme Stock ETF. Accordingly, the Fund will subject to the risks of the Meme Stock ETF, set forth below. In addition to these risks, the Meme Stock ETF is also subject to the following risks to which the Fund is also subject, which are described within the section entitled “Principal Risks”: Active Management Risk, Active Market Risk, Asset Class Risk, Concentration Risk, Cybersecurity Risk, Information Technology Risk, Operational Risk and Structural ETF Risk.

 

EQUITY SECURITIES RISK. Equity securities are subject to changes in value, and their values may be more volatile than those of other asset classes. Equity securities prices fluctuate for several reasons, including changes in investors’ perceptions of the financial condition of an issuer or the general condition of the relevant equity market, such as market volatility, or when political or economic events affecting an issuer occur. Common stock prices may be particularly sensitive to rising interest rates, as the cost of capital rises and borrowing costs increase. Common stocks generally subject their holders to more risks than preferred stocks and debt securities because common stockholders’ claims are subordinated to those of holders of preferred stocks and debt securities upon the bankruptcy of the issuer.

 

ISSUER RISK. The performance of an ETF depends on the performance of individual securities to which the ETF has exposure. Changes in the financial condition or credit rating of an issuer of those securities may cause the value of the securities to decline. There is no guarantee that an issuer that paid dividends in the past will continue to do so in the future or will continue paying dividends at the same level.

 

LARGE CAPITALIZATION COMPANIES RISK. Large capitalization companies may be less able than smaller capitalization companies to adapt to changing market conditions. Large capitalization companies may be more mature and subject to more limited growth potential compared with smaller capitalization companies. During different market cycles, the performance of large capitalization companies has trailed the overall performance of the broader securities markets.

 

MEME STOCKS RISK. Meme Stocks are characterized by high trading volumes and substantial price volatility, often driven by social media trends and investor interest. More traditional investing principles emphasize the intrinsic value of a company’s underlying business such as its cash flows, competitive position, and long-term growth prospects, when determining whether to buy or sell a particular security. In contrast, Meme Stocks often trade untethered from such fundamentals, driven instead by speculative fervor, viral momentum and in some instances coordinated buying and selling. The elevated trading volumes experienced by Meme Stocks may not persist outside of the “hype period,” potentially negatively affecting the liquidity and valuation of such stocks. While the Fund seeks to capitalize on the trading momentum associated with Meme Stocks, there is a substantial risk that such stocks may experience rapid and unpredictable price movements that could abate or reverse quickly. In the past, many Meme Stocks have had weakened underlying financial conditions, making them susceptible to substantial drops when trading momentum evaporates. Because a stock only becomes eligible for inclusion in the Fund’s portfolio after it has experienced a significant amount of liquidity and volatility, it is possible that by the time the Fund purchases shares of a Meme Stock it will have missed out on the initial gains, but will nevertheless experience any subsequent decline in value. Additionally, the identification of Meme Stocks is inherently subjective and may vary. As a result, stocks that are widely recognized as Meme Stocks may not be selected for inclusion in the Fund’s portfolio. Conversely, stocks included in the Fund may not be perceived as Meme Stocks by the broader market. Investors should be aware that investing in Meme Stocks involves a high degree of risk and may not be suitable for all investors. The volatile nature of these investments may lead to significant fluctuations in the Fund’s net asset value and could result in potential loss. In the past, several high-profile Meme Stocks have been the subjects of a “short squeeze.” A short squeeze can cause significant volatility in a stock’s price, potentially resulting in rapid and unpredictable price increases as short sellers are forced to cover their positions. This market dynamic may lead to prices that are temporarily disconnected from a company’s underlying fundamentals, increasing the risk of substantial losses for investors who enter or exit positions during periods of heightened volatility. Investors should be aware that short squeezes can amplify both gains and losses and may result in illiquidity or difficulty executing trades at desired prices.

 

MID CAPITALIZATION COMPANIES RISK. Mid capitalization companies may be more vulnerable to adverse general market or economic developments, and their securities may be less liquid and may experience greater price volatility than larger, more established companies as a result of several factors, including limited trading volumes, fewer products or financial resources, management inexperience and less publicly available information. Accordingly, such companies are generally subject to greater market risk than larger, more established companies.

 

SMALL CAPITALIZATION COMPANIES RISK. Small capitalization companies may be more vulnerable to adverse general market or economic developments, and their securities may be less liquid and may experience greater price volatility than large and mid capitalization companies as a result of several factors, including limited trading volumes, fewer products or financial resources, management inexperience and less publicly available information. Accordingly, such companies are generally subject to greater market risk than large and mid capitalization companies.

NON-DIVERSIFICATION RISK. As a “non-diversified” fund, the Fund may hold a smaller number of portfolio securities than many other funds. To the extent the Fund invests in a relatively small number of issuers, a decline in the market value of a particular security held by the Fund may affect its value more than if it invested in a larger number of issuers. The value of the Fund Shares may be more volatile than the values of shares of more diversified funds.

Roundhill Daily 2X Long Meme Stock ETF | MARKET RISK  
Prospectus [Line Items]  
Risk [Text Block]

Market Risk. Market risk is the risk that a particular investment, or Fund Shares in general, may fall in value. Securities are subject to market fluctuations caused by real or perceived adverse economic, political, and regulatory factors or market developments, changes in interest rates, disruptions to trade, impositions of tariffs and perceived trends in securities prices. Fund Shares could decline in value or underperform other investments. In addition, local, regional or global events such as war, acts of terrorism, market manipulation, government defaults, government shutdowns, regulatory actions, political changes, diplomatic developments, the imposition of sanctions and other similar measures, spread of infectious diseases or other public health issues, recessions, natural disasters, or other events could have a significant negative impact on the Fund and its investments. Any of such circumstances could have a materially negative impact on the value of Fund Shares, the liquidity of an investment, and may result in increased market volatility. During any such events, Fund Shares may trade at increased premiums or discounts to their net asset value, the bid/ask spread on Fund Shares may widen and the returns on investment may fluctuate.

Roundhill Daily 2X Long Meme Stock ETF | LIQUIDITY RISK  
Prospectus [Line Items]  
Risk [Text Block]

LIQUIDITY RISK. The market for derivatives that reference the Meme Stock ETF may be subject to periods of illiquidity. During such times it may be difficult or impossible to buy or sell a position at the desired price. Market disruptions or volatility can also make it difficult to find a counterparty willing to transact at a reasonable price and sufficient size. Illiquid markets may cause losses, which could be significant. The large size of the positions which the Fund may acquire increases the risk of illiquidity, may make its positions more difficult to liquidate, and may increase the losses incurred while trying to do so. Such large positions also may impact the price of derivatives on the Meme Stock ETF.

Roundhill Daily 2X Long Meme Stock ETF | ACTIVE MANAGEMENT RISK

ACTIVE MANAGEMENT RISK. The Fund is actively-managed and its performance reflects investment decisions that the Adviser and/or Sub-Adviser makes for the Fund. Such judgments about the Fund’s investments may prove to be incorrect. If the investments selected and the strategies employed by the Fund fail to produce the intended results, the Fund could underperform as compared to other funds with similar investment objectives and/or strategies, or could have negative returns.

ACTIVE MARKET RISK. Although Fund Shares are listed for trading on the Exchange, there can be no assurance that an active trading market for Fund Shares will develop or be maintained. Fund Shares trade on the Exchange at market prices that may be below, at or above the Fund’s net asset value. Securities, including Fund Shares, are subject to market fluctuations and liquidity constraints that may be caused by such factors as economic, political, or regulatory developments, changes in interest rates, and/or perceived trends in securities prices. Fund Shares could decline in value or underperform other investments.

Risk [Text Block]

COUNTERPARTY RISK. Fund transactions involving a counterparty are subject to the risk that the counterparty will not fulfill its obligation to the Fund. Counterparty risk may arise because of the counterparty’s financial condition (i.e., financial difficulties, bankruptcy, or insolvency), market activities and developments, or other reasons, whether foreseen or not. A counterparty’s inability to fulfill its obligation may result in significant financial loss to the Fund. The Fund may be unable to recover its investment from the counterparty or may obtain a limited recovery, and/or recovery may be delayed.

Roundhill Daily 2X Long Meme Stock ETF | CURRENT MARKET CONDITIONS RISK  
Prospectus [Line Items]  
Risk [Text Block]

CURRENT MARKET CONDITIONS RISK. Current market conditions risk is the risk that a particular investment, or Fund Shares in general, may fall in value due to current market conditions. As a means to fight inflation, which remains at elevated levels, the Federal Reserve and certain foreign central banks have raised interest rates; however, the Federal Reserve has recently lowered interest rates and may continue to do so. U.S. regulators have proposed several changes to market and issuer regulations which would directly impact the Fund, and any regulatory changes could adversely impact the Fund’s ability to achieve its investment strategies or make certain investments. Recent and potential future bank failures could result in disruption to the broader banking industry or markets generally and reduce confidence in financial institutions and the economy as a whole, which may also heighten market volatility and reduce liquidity. Additionally, challenges in commercial real estate markets, including rising interest rates, declining valuations and increasing vacancies, could have a broader impact on financial markets. The ongoing adversarial political climate in the United States, as well as political and diplomatic events both domestic and abroad, have and may continue to have an adverse impact the U.S. regulatory landscape, markets and investor behavior, which could have a negative impact on the Fund’s investments and operations. The change in administration resulting from the 2024 United States national elections could result in significant impacts to international trade relations, tax and immigration policies, and other aspects of the national and international political and financial landscape, which could affect, among other things, inflation and the securities markets generally. Other unexpected political, regulatory and diplomatic events within the U.S. and abroad may affect investor and consumer confidence and may adversely impact financial markets and the broader economy. For example, ongoing armed conflicts between Russia and Ukraine in Europe and among Israel, Iran, Hamas and other militant groups in the Middle East, have caused and could continue to cause significant market disruptions and volatility within the markets in Russia, Europe, the Middle East and the United States. The hostilities and sanctions resulting from those hostilities have and could continue to have a significant impact on certain Fund investments as well as Fund performance and liquidity. The economies of the United States and its trading partners, as well as the financial markets generally, may be adversely impacted by trade disputes, including the imposition of tariffs, and other matters. For example, the United States has imposed trade barriers and restrictions on China. In addition, the Chinese government is engaged in a longstanding dispute with Taiwan, continually threatening an invasion. If the political climate between the United States and China does not improve or continues to deteriorate, if China were to attempt invading Taiwan, or if other geopolitical conflicts develop or worsen, economies, markets and individual securities may be adversely affected, and the value of the Fund’s assets may go down. A public health crisis and the ensuing policies enacted by governments and central banks may cause significant volatility and uncertainty in global financial markets, negatively impacting global growth prospects. As the COVID-19 global pandemic illustrated, such events may affect certain geographic regions, countries, sectors and industries more significantly than others. Advancements in technology may also adversely impact markets and the overall performance of the Fund. For instance, the economy may be significantly impacted by the advanced development and increased regulation of artificial intelligence. Additionally, cyber security breaches of both government and non-government entities could have negative impacts on infrastructure and the ability of such entities, including the Fund, to operate properly. These events, and any other future events, may adversely affect the prices and liquidity of the Fund’s portfolio investments and could result in disruptions in the trading markets.

Failures or breaches of the electronic systems of the Fund, the Fund’s adviser, sub-adviser, distributor and other service providers, market makers, Authorized Participants or the issuers of securities in which the Fund invests have the ability to cause disruptions, negatively impact the Fund’s business operations and/or potentially result in financial losses to the Fund and its shareholders. While the Fund has established business continuity plans and risk management systems seeking to address system breaches or failures, there are inherent limitations in such plans and systems. Furthermore, the Fund cannot control the cybersecurity plans and systems of the Fund’s other service providers, market makers, Authorized Participants or issuers of securities in which the Fund invests.

Roundhill Daily 2X Long Meme Stock ETF | DERIVATIVES RISK  
Prospectus [Line Items]  
Risk [Text Block]

DERIVATIVES RISK. The use of derivative instruments involves risks different from, or possibly greater than, the risks associated with investing directly in securities and other traditional investments. These risks include: (i) the risk that the counterparty to a derivative transaction may not fulfill its contractual obligations; (ii) risk of mispricing or improper valuation; and (iii) the risk that changes in the value of the derivative may not correlate perfectly with the underlying asset. Derivative prices are highly volatile and may fluctuate substantially during a short period of time. Such prices are influenced by numerous factors that affect the markets, including, but not limited to: changing supply and demand relationships; government programs and policies; national and international political and economic events, changes in interest rates, inflation and deflation and changes in supply and demand relationships. Trading derivative instruments involves risks different from, or possibly greater than, the risks associated with investing directly in securities. Derivative contracts ordinarily have leverage inherent in their terms. The use of leverage may cause the Fund to liquidate portfolio positions when it would not be advantageous to do so in order to satisfy its obligations or to meet regulatory or contractual requirements for derivatives. The use of derivatives can magnify potential for gain or loss and, therefore, amplify the effects of market volatility on Fund Share price.

Roundhill Daily 2X Long Meme Stock ETF | ETF RISK  
Prospectus [Line Items]  
Risk [Text Block]

ETF RISK. The Fund may invest significantly in ETFs. The value of an ETF held by the Fund will fluctuate over time based on fluctuations in the values of the assets held by the ETF, which may be affected by changes in general economic conditions, expectations for future growth and profits, interest rates and the supply and demand for those assets. When the Fund invests in an ETF, it will bear a proportionate share of the ETF’s expenses. In addition, ETFs are subject to Active Market Risk, Operational Risk, Premium/Discount Risk and the Structural ETF Risks set forth below. Brokerage, tax and other expenses may negatively impact the performance of the ETF and, in turn, the value of the Fund Shares. An ETF that tracks an index may not exactly match the performance of the index due to cash drag, differences between the portfolio of the ETF and the components of the index, expenses and other factors.

Roundhill Daily 2X Long Meme Stock ETF | LEVERAGE RISK  
Prospectus [Line Items]  
Risk [Text Block]

LEVERAGE RISK. The Fund obtains investment exposure in excess of its net assets by utilizing leverage and may lose more money in market conditions that are adverse to its investment objective than a fund that does not utilize leverage. An investment in the Fund is exposed to the risk that a decline in the daily performance of the Meme Stock ETF will be magnified. This means that an investment in the Fund will be approximately reduced by an amount equal to 2% for every 1% daily decline in the market value of shares of the Meme Stock ETF, not including the costs of financing leverage and other operating expenses, which would further reduce its value. The Fund could theoretically lose an amount greater than its net assets in the event the market value of the Meme Stock ETF declines more than 50% in a single trading day. Leverage will also have the effect of magnifying any differences in the Fund’s correlation with the Meme Stock ETF.

The Fund relies on third-parties for a range of services, including custody.

Roundhill Daily 2X Long Meme Stock ETF | STRUCTURAL ETF RISKS  
Prospectus [Line Items]  
Risk [Text Block]

STRUCTURAL ETF RISKS. The Fund is an ETF. Accordingly, it is subject to certain risks associated with its unique structure.

 

Cash Transactions Risk. The Fund expects to effect a portion of its creations and redemptions for cash, rather than in-kind securities. Paying redemption proceeds in cash rather than through in-kind delivery of portfolio securities may require the Fund to dispose of or sell portfolio securities or other assets at an inopportune time to obtain the cash needed to meet redemption orders. This may cause the Fund to sell a security and recognize a capital gain or loss that might not have been incurred if it had made a redemption in-kind. As a result, the Fund may pay out higher or lower annual capital gains distributions than ETFs that redeem in-kind. The use of cash creations and redemptions will require the Fund to incur brokerage expenses when it buys and sells its portfolio investments and may also cause the Fund’s Shares to trade in the market at greater bid-ask spreads and greater premiums or discounts to the Fund’s NAV. Furthermore, the Fund may not be able to execute cash transactions for creation and redemption purposes at the same price used to determine the Fund’s NAV. To the extent that the maximum additional charge for creation or redemption transactions is insufficient to cover the execution shortfall, the Fund’s performance could be negatively impacted.

 

Market Participants Risk. Only an Authorized Participant may engage in creation or redemption transactions directly with the Fund, and none of those Authorized Participants is obligated to engage in creation and/or redemption transactions. The Fund has a limited number of institutions that may act as Authorized Participants on an agency basis (i.e., on behalf of other market participants). To the extent that Authorized Participants exit the business or are unable to proceed with creation or redemption orders with respect to the Fund and no other Authorized Participant is able to step forward to create or redeem, Fund Shares may be more likely to trade at a premium or discount to NAV and possibly face trading halts or delisting. The Fund may also rely on a small number of third-party market makers to provide a market for the purchase and sale of Fund Shares but such market makers are under no obligation to do so. Decisions by Authorized Participants or market makers to reduce their role or step away from these activities in times of market stress could inhibit the effectiveness of the arbitrage process in maintaining the relationship between the underlying values of the Fund’s portfolio securities and the Fund’s market price. Any trading halt or other problem relating to the trading activity of these market makers or any issues disrupting the Authorized Participants’ ability to proceed with creation and/or redemption orders could result in a dramatic change in the spread between the Fund’s net asset value and the price at which Fund Shares are trading on the Exchange, which could result in a decrease in value of Fund Shares. This reduced effectiveness could result in Fund Shares trading at a premium or discount to net asset value and also in greater than normal intraday bid-ask spreads Fund Shares.

 

Costs of Buying and Selling Fund Shares. Due to the costs of buying or selling Fund Shares, including brokerage commissions imposed by brokers and bid/ask spreads, frequent trading of Fund Shares may significantly reduce investment results and an investment in Fund Shares may not be advisable for investors who anticipate regularly making small investments.

 

Premium/Discount Risk. As with all ETFs, Fund Shares may be bought and sold in the secondary market at market prices. The trading prices of Fund Shares in the secondary market may differ from the Fund’s daily net asset value per share and there may be times when the market price of Fund Shares is more than the net asset value per Fund Share (premium) or less than the net asset value per Fund Share (discount). If a shareholder purchases Fund Shares at a time when the market price is at a premium to the net asset value or sells Fund Shares at a time when the market price is at a discount to the net asset value, the shareholder may pay more for, or receive less than, the underlying value of the Fund Shares, respectively. This risk is heightened in times of market volatility or periods of steep market declines.

 

Trading Risks. Although Fund Shares are listed for trading on the Exchange and may be traded on U.S. exchanges other than the Exchange, there can be no assurance that Fund Shares will trade with any volume, or at all, on any stock exchange. In stressed market conditions, the liquidity of Fund Shares may begin to mirror the liquidity of the Fund’s underlying portfolio holdings, which can be significantly less liquid than Fund Shares. Trading in Fund Shares on the Exchange may be halted due to market conditions or for reasons that, in the view of the Exchange, make trading in Fund Shares inadvisable. In addition, trading in Fund Shares on the Exchange is subject to trading halts caused by extraordinary market volatility pursuant to the Exchange’s “circuit breaker” rules. There can be no assurance that the requirements of the Exchange necessary to maintain the listing of the Fund will continue to be met or will remain unchanged.

Roundhill Daily 2X Long Meme Stock ETF | VALUATION RISK  
Prospectus [Line Items]  
Risk [Text Block]

VALUATION RISK. The Fund may hold securities or other assets that may be valued on the basis of factors other than market quotations. This may occur because the asset or security does not trade on a centralized exchange, or in times of market turmoil or reduced liquidity. There are multiple methods that can be used to value a portfolio holding when market quotations are not readily available. The value established for any portfolio holding at a point in time might differ from what would be produced using a different methodology or if it had been priced using market quotations. Portfolio holdings that are valued using techniques other than market quotations, including “fair valued” assets or securities, may be subject to greater fluctuation in their valuations from one day to the next than if market quotations were used. In addition, there is no assurance that the Fund could sell or close out a portfolio position for the value established for it at any time, and it is possible that the Fund would incur a loss because a portfolio position is sold or closed out at a discount to the valuation established by the Fund at that time. The Fund’s ability to value investments may be impacted by technological issues or errors by pricing services or other third-party service providers.

Roundhill Daily 2X Long Meme Stock ETF | SWAP AGREEMENTS RISK  
Prospectus [Line Items]  
Risk [Text Block]

SWAP AGREEMENTS RISK. The Fund will utilize swap agreements to derive its exposure to the Meme Stock ETF. Swap agreements may involve greater risks than direct investment in securities as they may be leveraged and are subject to credit risk, counterparty risk and valuation risk. A swap agreement could result in losses if the underlying reference or asset does not perform as anticipated. In addition, many swaps trade over-the-counter and may be considered illiquid. It may not be possible for the Fund to liquidate a swap position at an advantageous time or price, which may result in significant losses.

Roundhill Daily 2X Long Meme Stock ETF | AGGRESSIVE INVESTMENT RISK

AGGRESSIVE INVESTMENT RISK. The Fund employs investment strategies that involve greater risks than the strategies used by typical funds. The Fund’s use of leverage and derivatives could result in a shareholder losing the full principal value of his/her investment within a single day.

Roundhill Daily 2X Long Meme Stock ETF | COMPOUNDING AND MARKET VOLATILITY RISK  
Prospectus [Line Items]  
Risk [Text Block]

COMPOUNDING AND MARKET VOLATILITY RISK. The Fund has a daily leveraged investment objective and the Fund’s performance for periods greater than a trading day will be the result of each day’s returns compounded over the period, which is very likely to differ from two times (2X) the Meme Stock ETF’s performance, before fees and expenses. Compounding affects all investments but has a more significant impact on funds that are leveraged and that rebalance daily. For a leveraged fund, if adverse daily performance of the reference asset reduces the amount of a shareholder’s investment, any further adverse daily performance will lead to a smaller dollar loss because the shareholder’s investment had already been reduced by the prior adverse performance. Equally, however, if favorable daily performance of the reference asset increases the amount of a shareholder’s investment, the dollar amount lost due to future adverse performance will increase because the shareholder’s investment has increased.

 

The effect of compounding becomes more pronounced as the volatility and holding period of the Fund increases. The impact of compounding will impact each shareholder differently depending on the period of time an investment in the Fund is held and the volatility of the Meme Stock ETF during a shareholder’s holding period of an investment in the Fund.

 

The chart below provides examples of how the volatility of the Meme Stock ETF could affect the Fund’s performance. The chart illustrates the impact of two factors that affect the Fund’s performance – Meme Stock ETF volatility and Meme Stock ETF returns. The Meme Stock ETF returns show the percentage change in the market value of the Meme Stock ETF over the specified period, while the Meme Stock ETF’s volatility is a statistical measure of the magnitude of fluctuations in the returns during that time period. As illustrated below, even if returns of the Meme Stock ETF over two equal time periods is identical, different volatility in the Meme Stock ETF (i.e., fluctuations in the rates of return) during the two time periods could result in drastically different Fund performance for the two time periods because of compounding daily returns during the time periods.

 

Fund performance for periods greater than one single day can be estimated given any set of assumptions for the following factors: (i) Meme Stock ETF volatility; (ii) Meme Stock ETF performance; (iii) period of time; (iv) financing rates associated with leveraged exposure; (v) other Fund expenses; and (vi) dividends or interest paid by the Meme Stock ETF. The chart shows estimated Fund returns for a number of combinations of Meme Stock ETF volatility and Meme Stock ETF performance over a one-year period. Performance shown in the chart assumes that: (a) no dividends were paid by the Meme Stock ETF; (b) there were no Fund expenses; and (c) borrowing/lending rates (to obtain leveraged exposure) of 0%. If Fund expenses and/or actual borrowing/lending rates were reflected, the estimated returns would be different than those shown. Particularly during periods of higher Meme Stock ETF volatility, compounding will cause results for periods longer than a trading day to vary from two times (2X) the performance of the Meme Stock ETF.

 

As shown in the chart below, the Fund would be expected to lose 6.1% if the Meme Stock ETF provided no return over a one-year period during which the Meme Stock ETF experienced annualized volatility of 25%. If the Meme Stock ETF’s annualized volatility were to rise to 75%, the hypothetical loss for a one-year period widens to approximately 43.1%. At higher ranges of volatility, there is a chance of a significant loss of value in the Fund, even if the Meme Stock ETF’s return is flat. For instance, if the Meme Stock ETF’s annualized volatility is 100%, the Fund would be expected to lose 63.3% of its value, even if the cumulative Meme Stock ETF’s return for the year was 0%. The volatility of the instruments that reflect the market value of the Meme Stock ETF, such as swaps, may differ from the volatility of the Meme Stock ETF.

 

Areas shaded red represent those scenarios where the Fund can be expected to return less than two times (2X) the performance of the Meme Stock ETF and those shaded green represent those scenarios where the Fund can be expected to return more than two times (2X) the performance of the Meme Stock ETF. The Fund’s actual returns may be significantly better or worse than the returns shown below as a result of any of the factors discussed above or in the “Daily Correlation/Tracking Risk” below.

The annualized historical volatility rate of the Meme Stock ETF for the period from its inception on October 8, 2025 to November 3, 2025 was 81.30%. The annualized performance of the Meme Stock ETF for the period from its inception on October 8, 2025 to November 3, 2025 was -16.56%. Historical Meme Stock ETF volatility and performance are not necessarily indications of what volatility and performance of the Meme Stock ETF will be in the future.

 

For information regarding the effects of volatility and Meme Stock ETF performance on the long-term performance of the Fund, see “Understanding the Risks and Long-Term Performance of Daily Objective Funds – the Impact of Compounding” in the Fund’s statutory prospectus.

Roundhill Daily 2X Long Meme Stock ETF | INTRA-DAY INVESTMENT RISK  
Prospectus [Line Items]  
Risk [Text Block]

INTRA-DAY INVESTMENT RISK. The Fund seeks leveraged investment results from the close of the market on a given trading day until the close of the market on the subsequent trading day. The exact exposure of an investment in the Fund intraday in the secondary market is a function of the difference between the market value of the Meme Stock ETF at the market close on the first trading day and the market value of the Meme Stock ETF at the time of purchase. If the market value of the Meme Stock ETF increases in value, the Fund’s net assets will increase by approximately two times the amount of the Fund’s exposure. Conversely, if the market value of the Meme Stock ETF declines in value, the Fund’s net assets will decline by approximately two times the amount of the Fund’s exposure. Thus, an investor that purchases Fund Shares intra-day may experience performance that is greater than, or less than, the Fund’s stated multiple (2X) of the Meme Stock ETF.

 

If there is a significant intra-day market event and/or the Meme Stock ETF experiences a significant decrease, the Fund may not meet its investment objective or rebalance its portfolio appropriately.

Roundhill Daily 2X Long Meme Stock ETF | DAILY CORRELATION/TRACKING RISK  
Prospectus [Line Items]  
Risk [Text Block]

DAILY CORRELATION/TRACKING RISK. There is no guarantee that the Fund will achieve a high degree of correlation to the Meme Stock ETF and therefore achieve its daily leveraged investment objective. To achieve a high degree of correlation with the Meme Stock ETF, the Fund seeks to rebalance its portfolio daily to keep leverage consistent with its daily leveraged investment objective. The possibility of the Fund being materially over- or under-exposed to the Meme Stock ETF increases on days when shares of the Meme Stock ETF are volatile near the close of the trading day. Market disruptions, regulatory restrictions and extreme volatility will also adversely affect the Fund’s ability to adjust exposure to the required levels.

 

The Fund may also utilize derivatives that do not use the Meme Stock ETF as the reference asset. Under such circumstances, the Fund’s returns may not directly correlate with the returns of the Meme Stock ETF. Additionally, the Fund may have difficulty achieving its daily leveraged investment objective due to fees, expenses, transaction costs, financing costs related to the use of derivatives, investments in ETFs, directly or indirectly, income items, valuation methodology, accounting standards and disruptions or illiquidity in the markets for the securities or derivatives held by the Fund. The Fund may be subject to large movements of assets into and out of the Fund, potentially resulting in the Fund being over- or under-exposed to the Meme Stock ETF. The Fund may take or refrain from taking positions to improve the tax efficiency or to comply with various regulatory restrictions, either of which may negatively impact the Fund’s correlation to the Meme Stock ETF.

Roundhill Daily 2X Long Meme Stock ETF | FUTURES CONTRACT RISK  
Prospectus [Line Items]  
Risk [Text Block]

FUTURES CONTRACT RISK. The Fund may utilize futures contracts. Risks of futures contracts include: (i) an imperfect correlation between the value of the futures contract and the underlying asset; (ii) possible lack of a liquid secondary market; (iii) the inability to close a futures contract when desired; (iv) losses caused by unanticipated market movements, which may be unlimited; (v) an obligation for the Fund to make daily cash payments to maintain its required margin, particularly at times when the Fund may have insufficient cash; and (vi) unfavorable execution prices from rapid selling. Unlike equities, which typically entitle the holder to a continuing stake in a corporation, futures contracts normally specify a certain date for settlement in cash based on the reference asset. As the futures contracts approach expiration, they may be replaced by similar contracts that have a later expiration. This process is referred to as “rolling.” If the market for these contracts is in “contango,” meaning that the prices of futures contracts in the nearer months are lower than the price of contracts in the distant months, the sale of the near-term month contract would be at a lower price than the longer-term contract, resulting in a cost to “roll” the futures contract. The actual realization of a potential roll cost will be dependent upon the difference in price of the near and distant contract. The costs associated with rolling futures contracts may have a significant adverse impact on the performance of the Fund.

Roundhill Daily 2X Long Meme Stock ETF | MEME STOCK ETF RISKS  
Prospectus [Line Items]  
Risk [Text Block]

MEME STOCK ETF RISKS. The Fund will have significant exposure to the Meme Stock ETF through its investments in shares of the Meme Stock ETF and investments in financial instruments that provide exposure to the Meme Stock ETF and the securities it holds. Accordingly, the Fund will subject to the risks of the Meme Stock ETF, set forth below. In addition to these risks, the Meme Stock ETF is also subject to the following risks to which the Fund is also subject, which are described within the section entitled “Principal Risks”: Active Management Risk, Active Market Risk, Asset Class Risk, Concentration Risk, Cybersecurity Risk, Information Technology Risk, Operational Risk and Structural ETF Risk.

 

EQUITY SECURITIES RISK. Equity securities are subject to changes in value, and their values may be more volatile than those of other asset classes. Equity securities prices fluctuate for several reasons, including changes in investors’ perceptions of the financial condition of an issuer or the general condition of the relevant equity market, such as market volatility, or when political or economic events affecting an issuer occur. Common stock prices may be particularly sensitive to rising interest rates, as the cost of capital rises and borrowing costs increase. Common stocks generally subject their holders to more risks than preferred stocks and debt securities because common stockholders’ claims are subordinated to those of holders of preferred stocks and debt securities upon the bankruptcy of the issuer.

 

ISSUER RISK. The performance of an ETF depends on the performance of individual securities to which the ETF has exposure. Changes in the financial condition or credit rating of an issuer of those securities may cause the value of the securities to decline. There is no guarantee that an issuer that paid dividends in the past will continue to do so in the future or will continue paying dividends at the same level.

 

LARGE CAPITALIZATION COMPANIES RISK. Large capitalization companies may be less able than smaller capitalization companies to adapt to changing market conditions. Large capitalization companies may be more mature and subject to more limited growth potential compared with smaller capitalization companies. During different market cycles, the performance of large capitalization companies has trailed the overall performance of the broader securities markets.

 

LEGISLATION AND LITIGATION RISK. Legislation or litigation that affects the value of assets or securities held by the Meme Stock ETF may reduce the value of the Fund. From time to time, various legislative initiatives are proposed that may have a negative impact on certain assets or securities in which the Meme Stock ETF invests. In addition, litigation regarding any of the assets or securities owned by the Meme Stock ETF may negatively impact the value of the Shares. Such legislation or litigation may cause the Fund to lose value.

 

MEME STOCKS RISK. Meme Stocks are characterized by high trading volumes and substantial price volatility, often driven by social media trends and investor interest. More traditional investing principles emphasize the intrinsic value of a company’s underlying business such as its cash flows, competitive position, and long-term growth prospects, when determining whether to buy or sell a particular security. In contrast, Meme Stocks often trade untethered from such fundamentals, driven instead by speculative fervor, viral momentum and in some instances coordinated buying and selling. The elevated trading volumes experienced by Meme Stocks may not persist outside of the “hype period,” potentially negatively affecting the liquidity and valuation of such stocks. While the Fund seeks to capitalize on the trading momentum associated with Meme Stocks, there is a substantial risk that such stocks may experience rapid and unpredictable price movements that could abate or reverse quickly. In the past, many Meme Stocks have had weakened underlying financial conditions, making them susceptible to substantial drops when trading momentum evaporates. Because a stock only becomes eligible for inclusion in the Fund’s portfolio after it has experienced a significant amount of liquidity and volatility, it is possible that by the time the Fund purchases shares of a Meme Stock it will have missed out on the initial gains, but will nevertheless experience any subsequent decline in value. Additionally, the identification of Meme Stocks is inherently subjective and may vary. As a result, stocks that are widely recognized as Meme Stocks may not be selected for inclusion in the Fund’s portfolio. Conversely, stocks included in the Fund may not be perceived as Meme Stocks by the broader market. Investors should be aware that investing in Meme Stocks involves a high degree of risk and may not be suitable for all investors. The volatile nature of these investments may lead to significant fluctuations in the Fund’s net asset value and could result in potential loss. In the past, several high-profile Meme Stocks have been the subjects of a “short squeeze.” A short squeeze can cause significant volatility in a stock’s price, potentially resulting in rapid and unpredictable price increases as short sellers are forced to cover their positions. This market dynamic may lead to prices that are temporarily disconnected from a company’s underlying fundamentals, increasing the risk of substantial losses for investors who enter or exit positions during periods of heightened volatility. Investors should be aware that short squeezes can amplify both gains and losses and may result in illiquidity or difficulty executing trades at desired prices.

 

MID CAPITALIZATION COMPANIES RISK. Mid capitalization companies may be more vulnerable to adverse general market or economic developments, and their securities may be less liquid and may experience greater price volatility than larger, more established companies as a result of several factors, including limited trading volumes, fewer products or financial resources, management inexperience and less publicly available information. Accordingly, such companies are generally subject to greater market risk than larger, more established companies.

 

SMALL CAPITALIZATION COMPANIES RISK. Small capitalization companies may be more vulnerable to adverse general market or economic developments, and their securities may be less liquid and may experience greater price volatility than large and mid capitalization companies as a result of several factors, including limited trading volumes, fewer products or financial resources, management inexperience and less publicly available information. Accordingly, such companies are generally subject to greater market risk than large and mid capitalization companies.

NON-DIVERSIFICATION RISK. As a “non-diversified” fund, the Fund may hold a smaller number of portfolio securities than many other funds. To the extent the Fund invests in a relatively small number of issuers, a decline in the market value of a particular security held by the Fund may affect its value more than if it invested in a larger number of issuers. The value of the Fund Shares may be more volatile than the values of shares of more diversified funds.

Roundhill APP WeeklyPay™ ETF | MARKET RISK  
Prospectus [Line Items]  
Risk [Text Block]

Market Risk. Market risk is the risk that a particular investment, or Fund Shares in general, may fall in value. Securities are subject to market fluctuations caused by real or perceived adverse economic, political, and regulatory factors or market developments, changes in interest rates, disruptions to trade, impositions of tariffs and perceived trends in securities prices. Fund Shares could decline in value or underperform other investments. In addition, local, regional or global events such as war, acts of terrorism, market manipulation, government defaults, government shutdowns, regulatory actions, political changes, diplomatic developments, the imposition of sanctions and other similar measures, spread of infectious diseases or other public health issues, recessions, natural disasters, or other events could have a significant negative impact on the Fund and its investments. Any of such circumstances could have a materially negative impact on the value of Fund Shares, the liquidity of an investment, and may result in increased market volatility. During any such events, Fund Shares may trade at increased premiums or discounts to their net asset value, the bid/ask spread on Fund Shares may widen and the returns on investment may fluctuate.

Roundhill APP WeeklyPay™ ETF | LIQUIDITY RISK  
Prospectus [Line Items]  
Risk [Text Block]

LIQUIDITY RISK. The market for swap agreements that reference APP shares may be subject to periods of illiquidity. During such times it may be difficult or impossible to buy or sell a position at the desired price. Market disruptions or volatility can also make it difficult to find a counterparty willing to transact at a reasonable price and sufficient size. Illiquid markets may cause losses, which could be significant. The large size of the positions which the Fund may acquire increases the risk of illiquidity, may make its positions more difficult to liquidate, and may increase the losses incurred while trying to do so. Such large positions also may impact the price of swap agreements on APP shares.

Roundhill APP WeeklyPay™ ETF | ACTIVE MANAGEMENT RISK

ACTIVE MANAGEMENT RISK. The Fund is actively-managed and its performance reflects investment decisions that the Adviser and/or Sub-Adviser makes for the Fund. Such judgments about the Fund’s investments may prove to be incorrect. If the investments selected and the strategies employed by the Fund fail to produce the intended results, the Fund could underperform as compared to other funds with similar investment objectives and/or strategies, or could have negative returns.

Roundhill APP WeeklyPay™ ETF | ACTIVE MARKET RISK

ACTIVE MARKET RISK. Although Fund Shares are listed for trading on the Exchange, there can be no assurance that an active trading market for Fund Shares will develop or be maintained. Fund Shares trade on the Exchange at market prices that may be below, at or above the Fund’s net asset value. Securities, including Fund Shares, are subject to market fluctuations and liquidity constraints that may be caused by such factors as economic, political, or regulatory developments, changes in interest rates, and/or perceived trends in securities prices. Fund Shares could decline in value or underperform other investments.

CONCENTRATION RISK. The Fund is susceptible to an increased risk of loss, including losses due to adverse events that affect the Fund’s investments more than the market as a whole, to the extent that the Fund’s investments are concentrated in investments that provide exposure to APP and the industry to which it is assigned.

COUNTERPARTY RISK. Fund transactions involving a counterparty are subject to the risk that the counterparty will not fulfill its obligation to the Fund. Counterparty risk may arise because of the counterparty’s financial condition (i.e., financial difficulties, bankruptcy, or insolvency), market activities and developments, or other reasons, whether foreseen or not. A counterparty’s inability to fulfill its obligation may result in significant financial loss to the Fund. The Fund may be unable to recover its investment from the counterparty or may obtain a limited recovery, and/or recovery may be delayed.

Roundhill APP WeeklyPay™ ETF | CURRENT MARKET CONDITIONS RISK  
Prospectus [Line Items]  
Risk [Text Block]

CURRENT MARKET CONDITIONS RISK. Current market conditions risk is the risk that a particular investment, or Fund Shares in general, may fall in value due to current market conditions. As a means to fight inflation, which remains at elevated levels, the Federal Reserve and certain foreign central banks have raised interest rates; however, the Federal Reserve has recently lowered interest rates and may continue to do so. U.S. regulators have proposed several changes to market and issuer regulations which would directly impact the Fund, and any regulatory changes could adversely impact the Fund’s ability to achieve its investment strategies or make certain investments. Recent and potential future bank failures could result in disruption to the broader banking industry or markets generally and reduce confidence in financial institutions and the economy as a whole, which may also heighten market volatility and reduce liquidity. Additionally, challenges in commercial real estate markets, including rising interest rates, declining valuations and increasing vacancies, could have a broader impact on financial markets. The ongoing adversarial political climate in the United States, as well as political and diplomatic events both domestic and abroad, have and may continue to have an adverse impact the U.S. regulatory landscape, markets and investor behavior, which could have a negative impact on the Fund’s investments and operations. The change in administration resulting from the 2024 United States national elections could result in significant impacts to international trade relations, tax and immigration policies, and other aspects of the national and international political and financial landscape, which could affect, among other things, inflation and the securities markets generally. Other unexpected political, regulatory and diplomatic events within the U.S. and abroad may affect investor and consumer confidence and may adversely impact financial markets and the broader economy. For example, ongoing armed conflicts between Russia and Ukraine in Europe and among Israel, Iran, Hamas and other militant groups in the Middle East, have caused and could continue to cause significant market disruptions and volatility within the markets in Russia, Europe, the Middle East and the United States. The hostilities and sanctions resulting from those hostilities have and could continue to have a significant impact on certain Fund investments as well as Fund performance and liquidity. The economies of the United States and its trading partners, as well as the financial markets generally, may be adversely impacted by trade disputes, including the imposition of tariffs, and other matters. For example, the United States has imposed trade barriers and restrictions on China. In addition, the Chinese government is engaged in a longstanding dispute with Taiwan, continually threatening an invasion. If the political climate between the United States and China does not improve or continues to deteriorate, if China were to attempt invading Taiwan, or if other geopolitical conflicts develop or worsen, economies, markets and individual securities may be adversely affected, and the value of the Fund’s assets may go down. A public health crisis and the ensuing policies enacted by governments and central banks may cause significant volatility and uncertainty in global financial markets, negatively impacting global growth prospects. As the COVID-19 global pandemic illustrated, such events may affect certain geographic regions, countries, sectors and industries more significantly than others. Advancements in technology may also adversely impact markets and the overall performance of the Fund. For instance, the economy may be significantly impacted by the advanced development and increased regulation of artificial intelligence. Additionally, cyber security breaches of both government and non-government entities could have negative impacts on infrastructure and the ability of such entities, including the Fund, to operate properly. These events, and any other future events, may adversely affect the prices and liquidity of the Fund’s portfolio investments and could result in disruptions in the trading markets.

Roundhill APP WeeklyPay™ ETF | CYBERSECURITY RISK  
Prospectus [Line Items]  
Risk [Text Block]

CYBERSECURITY RISK. Failures or breaches of the electronic systems of the Fund, the Fund’s adviser, sub-adviser, distributor and other service providers, market makers, Authorized Participants or the issuers of securities in which the Fund invests have the ability to cause disruptions, negatively impact the Fund’s business operations and/or potentially result in financial losses to the Fund and its shareholders. While the Fund has established business continuity plans and risk management systems seeking to address system breaches or failures, there are inherent limitations in such plans and systems. Furthermore, the Fund cannot control the cybersecurity plans and systems of the Fund’s other service providers, market makers, Authorized Participants or issuers of securities in which the Fund invests.

Roundhill APP WeeklyPay™ ETF | DEBT SECURITIES RISK  
Prospectus [Line Items]  
Risk [Text Block]

DEBT SECURITIES RISK. Investments in debt securities subject the holder to the credit risk of the issuer. Credit risk refers to the possibility that the issuer or other obligor of a security will not be able or willing to make payments of interest and principal when due. Generally, the value of debt securities will change inversely with changes in interest rates. To the extent that interest rates rise, certain underlying obligations may be paid off substantially slower than originally anticipated and the value of those securities may fall sharply. During periods of falling interest rates, the income received by the Fund may decline. If the principal on a debt security is prepaid before expected, the prepayments of principal may have to be reinvested in obligations paying interest at lower rates. Debt securities generally do not trade on a securities exchange making them generally less liquid and more difficult to value than common stock.

Roundhill APP WeeklyPay™ ETF | DERIVATIVES RISK  
Prospectus [Line Items]  
Risk [Text Block]

DERIVATIVES RISK. The use of derivative instruments involves risks different from, or possibly greater than, the risks associated with investing directly in securities and other traditional investments. These risks include: (i) the risk that the counterparty to a derivative transaction may not fulfill its contractual obligations; (ii) risk of mispricing or improper valuation; and (iii) the risk that changes in the value of the derivative may not correlate perfectly with the underlying asset. Derivative prices are highly volatile and may fluctuate substantially during a short period of time. Such prices are influenced by numerous factors that affect the markets, including, but not limited to: changing supply and demand relationships; government programs and policies; national and international political and economic events, changes in interest rates, inflation and deflation and changes in supply and demand relationships. Trading derivative instruments involves risks different from, or possibly greater than, the risks associated with investing directly in securities. Derivative contracts ordinarily have leverage inherent in their terms. The use of leverage may cause the Fund to liquidate portfolio positions when it would not be advantageous to do so in order to satisfy its obligations or to meet regulatory or contractual requirements for derivatives. The use of derivatives can magnify potential for gain or loss and, therefore, amplify the effects of market volatility on share price.

Roundhill APP WeeklyPay™ ETF | DISTRIBUTION TAX RISK  
Prospectus [Line Items]  
Risk [Text Block]

DISTRIBUTION TAX RISK. The Fund currently expects to make distributions on a weekly basis. Such frequent distributions may expose investors to increased tax liabilities. However, these distributions may exceed the Fund’s income and gains for the Fund’s taxable year. Distributions in excess of the Fund’s current and accumulated earnings and profits will be treated as a return of capital. A return of capital distribution generally will not be taxable but will reduce the shareholder’s cost basis and will result in a higher capital gain or lower capital loss when those Fund Shares on which the distribution was received are sold. Once a Fund shareholder’s cost basis is reduced to zero, further distributions will be treated as capital gain if the Fund shareholder holds Fund Shares as capital assets. Additionally, any capital returned through distributions will be distributed after payment of Fund fees and expenses. Because a portion of the Fund’s distributions may consist of return of capital, the Fund may not be an appropriate investment for investors who do not want their principal investment in the Fund to decrease over time or who do not wish to receive return of capital in a given period. In the event that a shareholder purchases Fund Shares shortly before a distribution by the Fund, the entire distribution may be taxable to the shareholder even though a portion of the distribution effectively represents a return of the purchase price.

Roundhill APP WeeklyPay™ ETF | ETF RISK  
Prospectus [Line Items]  
Risk [Text Block]

ETF RISK. The Fund may invest in ETFs. The value of an ETF held by the Fund will fluctuate over time based on fluctuations in the values of the assets held by the ETF, which may be affected by changes in general economic conditions, expectations for future growth and profits, interest rates and the supply and demand for those assets. When the Fund invests in an ETF, it will bear a proportionate share of the ETF’s expenses. Brokerage, tax and other expenses may negatively impact the performance of the ETF and, in turn, the value of the Fund Shares. An ETF that tracks an index may not exactly match the performance of the index due to cash drag, differences between the portfolio of the ETF and the components of the index, expenses and other factors.

Roundhill APP WeeklyPay™ ETF | INFLATION RISK

Risk [Text Block]

INFLATION RISK. Inflation risk is the risk that the value of assets or income from investments will be less in the future as inflation decreases the value of money. As inflation increases, the present value of the Fund’s assets and distributions may decline. This risk is more prevalent with respect to fixed income securities held by the Fund.

Roundhill APP WeeklyPay™ ETF | Interest Rate Risk [Member]  
Prospectus [Line Items]  
Risk [Text Block]

INTEREST RATE RISK. Interest rate risk is the risk that the value of the debt securities in the Fund’s portfolio will decline because of rising market interest rates. Interest rate risk is generally lower for shorter term debt securities and higher for longer-term debt securities. Duration is a reasonably accurate measure of a debt security’s price sensitivity to changes in interest rates and a common measure of interest rate risk. Duration measures a debt security’s expected life on a present value basis, taking into account the debt security’s yield, interest payments and final maturity. In general, duration represents the expected percentage change in the value of a security for an immediate 1% change in interest rates. For example, the price of a debt security with a three-year duration would be expected to drop by approximately 3% in response to a 1% increase in interest rates. Therefore, prices of debt securities with shorter durations tend to be less sensitive to interest rate changes than debt securities with longer durations. As the value of a debt security changes over time, so will its duration.

Roundhill APP WeeklyPay™ ETF | LEGISLATION AND LITIGATION RISK  
Prospectus [Line Items]  
Risk [Text Block]

LEGISLATION AND LITIGATION RISK. Legislation or litigation that affects the value of assets or securities held by the Fund may reduce the value of the Fund. From time to time, various legislative initiatives are proposed that may have a negative impact on certain assets or securities in which the Fund invests. In addition, litigation regarding any of the assets or securities owned by the Fund may negatively impact the value of the Shares. Such legislation or litigation may cause the Fund to lose value or may result in higher portfolio turnover if the Adviser determines to sell such a holding.

Roundhill APP WeeklyPay™ ETF | LEVERAGE RISK  
Prospectus [Line Items]  
Risk [Text Block]

LEVERAGE RISK. The Fund obtains investment exposure in excess of its net assets by utilizing leverage and may lose more money in market conditions that are adverse to its investment objectives than a fund that does not utilize leverage. An investment in the Fund is exposed to the risk that a decline in the weekly performance of shares of APP will be magnified. This means that an investment in the Fund will be reduced by an amount equal to 1.2% for every 1% weekly decline in the market value of the APP shares, not including the costs of financing leverage and other operating expenses, which would further reduce its value. The Fund could theoretically lose an amount greater than its net assets in the event the market value of APP shares decline more than 83.33% over a calendar week. Leverage will also have the effect of magnifying any differences in the Fund’s correlation with APP shares.

Roundhill APP WeeklyPay™ ETF | MONEY MARKET INSTRUMENTS RISK  
Prospectus [Line Items]  
Risk [Text Block]

MONEY MARKET INSTRUMENTS RISK. The value of money market instruments may be affected by changing interest rates and by changes in the credit ratings of the investments. If a significant amount of the Fund’s assets are invested in money market instruments, it will be more difficult for the Fund to achieve its investment objectives. An investment in a money market fund is not insured or guaranteed by the FDIC or any other government agency. It is possible to lose money by investing in a money market fund.

Roundhill APP WeeklyPay™ ETF | OPERATIONAL RISK  
Prospectus [Line Items]  
Risk [Text Block]

OPERATIONAL RISK. The Fund is subject to risks arising from various operational factors, including, but not limited to, human error, processing and communication errors, errors of the Fund’s service providers, counterparties or other third-parties, failed or inadequate processes and technology or systems failures. The Fund relies on third-parties for a range of services, including custody. Any delay or failure relating to engaging or maintaining such service providers may affect the Fund’s ability to meet its investment objectives. Although the Fund and the Adviser seek to reduce these operational risks through controls and procedures, there is no way to completely protect against such risks.

Roundhill APP WeeklyPay™ ETF | SPECIAL TAX RISK  
Prospectus [Line Items]  
Risk [Text Block]

SPECIAL TAX RISK. The Fund intends to qualify annually and to elect to be treated as a regulated investment company under the Internal Revenue Code of 1986, as amended (the “Code”). To qualify for the favorable U.S. federal income tax treatment generally accorded to regulated investment companies, the Fund must, among other things, (i) derive in each taxable year at least 90% of its gross income from dividends, interest, payments with respect to securities loans and gains from the sale or other disposition of stock, securities or foreign currencies or other income derived with respect to its business of investing in such stock, securities or currencies, or net income derived from interests in certain publicly traded partnerships; (ii) diversify its holdings so that, at the end of each quarter of the taxable year, (a) at least 50% of the market value of the Fund’s assets is represented by cash and cash items (including receivables), U.S. government securities, the securities of other regulated investment companies and other securities, with such other securities of any one issuer generally limited for the purposes of this calculation to an amount not greater than 5% of the value of the Fund’s total assets and not greater than 10% of the outstanding voting securities of such issuer, and (b) not more than 25% of the value of its total assets is invested in the securities (other than U.S. government securities or the securities of other regulated investment companies) of any one issuer, or two or more issuers which the Fund controls which are engaged in the same, similar or related trades or businesses, or the securities of one or more of certain publicly traded partnerships; and (iii) distribute at least 90% of its investment company taxable income (which includes, among other items, dividends, interest and net short-term capital gains in excess of net long-term capital losses) and at least 90% of its net tax-exempt interest income each taxable year. There are certain exceptions for failure to qualify if the failure is for reasonable cause or is de minimis, and certain corrective action is taken and certain tax payments are made by the Fund.

 

The authority with regard to swaps entered into by regulated investment companies is unclear both as to the qualification under the income test and the identification of the issuer under the diversification test. The Fund intends to take the position that because the swaps held by the Fund reference securities that the income on the swaps are “other income” from the Fund’s business of investing in stocks and securities. In addition, the Fund intends to manage its investments in the swaps so that neither the exposure to issuer of the referenced security nor the exposure to any one counterparty of the swaps will exceed 25% of the gross value of the Fund’s portfolio at the end of any quarter.

 

If the Fund were to fail to meet the qualifying income test or asset diversification test and fail to qualify as a RIC, it would be taxed in the same manner as an ordinary corporation, and distributions to its shareholders would not be deductible by the Fund in computing its taxable income, which would adversely affect the Fund’s performance.

Roundhill APP WeeklyPay™ ETF | STRUCTURAL ETF RISKS  
Prospectus [Line Items]  
Risk [Text Block]

STRUCTURAL ETF RISKS. The Fund is an ETF. Accordingly, it is subject to certain risks associated with its unique structure.

 

Market Participants Risk. Only an Authorized Participant may engage in creation or redemption transactions directly with the Fund, and none of those Authorized Participants is obligated to engage in creation and/or redemption transactions. The Fund has a limited number of institutions that may act as Authorized Participants on an agency basis (i.e., on behalf of other market participants). To the extent that Authorized Participants exit the business or are unable to proceed with creation or redemption orders with respect to the Fund and no other Authorized Participant is able to step forward to create or redeem, Fund Shares may be more likely to trade at a premium or discount to NAV and possibly face trading halts or delisting. The Fund may also rely on a small number of third-party market makers to provide a market for the purchase and sale of Fund Shares but such market makers are under no obligation to do so. Decisions by Authorized Participants or market makers to reduce their role or step away from these activities in times of market stress could inhibit the effectiveness of the arbitrage process in maintaining the relationship between the underlying values of the Fund’s portfolio securities and the Fund’s market price. Any trading halt or other problem relating to the trading activity of these market makers or any issues disrupting the Authorized Participants’ ability to proceed with creation and/or redemption orders could result in a dramatic change in the spread between the Fund’s net asset value and the price at which Fund Shares are trading on the Exchange, which could result in a decrease in value of Fund Shares. This reduced effectiveness could result in Fund Shares trading at a premium or discount to net asset value and also in greater than normal intraday bid-ask spreads Fund Shares.

 

Cash Transactions Risk. The Fund currently expects to effect a significant portion of its creations and redemptions for cash, rather than in-kind securities. Paying redemption proceeds in cash rather than through in-kind delivery of portfolio securities may require the Fund to dispose of or sell portfolio securities or other assets at an inopportune time to obtain the cash needed to meet redemption orders. This may cause the Fund to sell a security and recognize a capital gain or loss that might not have been incurred if it had made a redemption in-kind. As a result, the Fund may pay out higher or lower annual capital gains distributions than ETFs that redeem in-kind. The use of cash creations and redemptions may also cause the Fund’s Shares to trade in the market at greater bid-ask spreads or greater premiums or discounts to the Fund’s NAV. Furthermore, the Fund may not be able to execute cash transactions for creation and redemption purposes at the same price used to determine the Fund’s NAV. To the extent that the maximum additional charge for creation or redemption transactions is insufficient to cover the execution shortfall, the Fund’s performance could be negatively impacted.

 

Costs of Buying and Selling Fund Shares. Due to the costs of buying or selling Fund Shares, including brokerage commissions imposed by brokers and bid/ask spreads, frequent trading of Fund Shares may significantly reduce investment results and an investment in Fund Shares may not be advisable for investors who anticipate regularly making small investments.

 

Premium/Discount Risk. As with all ETFs, Fund Shares may be bought and sold in the secondary market at market prices. The trading prices of Fund Shares in the secondary market may differ from the Fund’s daily net asset value per share and there may be times when the market price of the shares is more than the net asset value per share (premium) or less than the net asset value per share (discount). If a shareholder purchases Fund Shares at a time when the market price is at a premium to the net asset value or sells Fund Shares at a time when the market price is at a discount to the net asset value, the shareholder may pay more for, or receive less than, the underlying value of the Fund Shares, respectively. This risk is heightened in times of market volatility or periods of steep market declines.

 

Trading Risks. Although Fund Shares are listed for trading on the Exchange and may be traded on U.S. exchanges other than the Exchange, there can be no assurance that Fund Shares will trade with any volume, or at all, on any stock exchange. In stressed market conditions, the liquidity of Fund Shares may begin to mirror the liquidity of the Fund’s underlying portfolio holdings, which can be significantly less liquid than Fund Shares. Trading in Fund Shares on the Exchange may be halted due to market conditions or for reasons that, in the view of the Exchange, make trading in Fund Shares inadvisable. In addition, trading in Fund Shares on the Exchange is subject to trading halts caused by extraordinary market volatility pursuant to the Exchange’s “circuit breaker” rules. There can be no assurance that the requirements of the Exchange necessary to maintain the listing of the Fund will continue to be met or will remain unchanged.

Roundhill APP WeeklyPay™ ETF | U.S. GOVERNMENT SECURITIES RISK  
Prospectus [Line Items]  
Risk [Text Block]

U.S. GOVERNMENT SECURITIES RISK. U.S. government securities are subject to interest rate risk but generally do not involve the credit risks associated with investments in other types of debt securities. As a result, the yields available from U.S. government securities are generally lower than the yields available from other debt securities. U.S. government securities are guaranteed only as to the timely payment of interest and the payment of principal when held to maturity.

Roundhill APP WeeklyPay™ ETF | VALUATION RISK  
Prospectus [Line Items]  
Risk [Text Block]

VALUATION RISK. The Fund may hold securities or other assets that may be valued on the basis of factors other than market quotations. This may occur because the asset or security does not trade on a centralized exchange, or in times of market turmoil or reduced liquidity. There are multiple methods that can be used to value a portfolio holding when market quotations are not readily available. The value established for any portfolio holding at a point in time might differ from what would be produced using a different methodology or if it had been priced using market quotations. Portfolio holdings that are valued using techniques other than market quotations, including “fair valued” assets or securities, may be subject to greater fluctuation in their valuations from one day to the next than if market quotations were used. In addition, there is no assurance that the Fund could sell or close out a portfolio position for the value established for it at any time, and it is possible that the Fund would incur a loss because a portfolio position is sold or closed out at a discount to the valuation established by the Fund at that time. The Fund’s ability to value investments may be impacted by technological issues or errors by pricing services or other third-party service providers.

Roundhill APP WeeklyPay™ ETF | EQUITY SECURITIES RISK  
Prospectus [Line Items]  
Risk [Text Block]

EQUITY SECURITIES RISK. Equity securities are subject to changes in value, and their values may be more volatile than those of other asset classes. Equity securities prices fluctuate for several reasons, including changes in investors’ perceptions of the financial condition of an issuer or the general condition of the relevant equity market, such as market volatility, or when political or economic events affecting an issuer occur. Common stock prices may be particularly sensitive to rising interest rates, as the cost of capital rises and borrowing costs increase. Common stocks generally subject their holders to more risks than preferred stocks and debt securities because common stockholders’ claims are subordinated to those of holders of preferred stocks and debt securities upon the bankruptcy of the issuer.

Roundhill APP WeeklyPay™ ETF | SWAP AGREEMENTS RISK  
Prospectus [Line Items]  
Risk [Text Block]

SWAP AGREEMENTS RISK. The Fund will utilize swap agreements to derive its exposure to shares of APP. Swap agreements may involve greater risks than direct investment in securities as they may be leveraged and are subject to credit risk, counterparty risk and valuation risk. A swap agreement could result in losses if the underlying reference or asset does not perform as anticipated. In addition, many swaps trade over-the-counter and may be considered illiquid. It may not be possible for the Fund to liquidate a swap position at an advantageous time or price, which may result in significant losses.

Roundhill APP WeeklyPay™ ETF | NEW FUND RISK  
Prospectus [Line Items]

NEW FUND RISK. The Fund is a recently organized investment company with a limited operating history. As a result, prospective investors have a limited track record or history on which to base their investment decision.

Roundhill APP WeeklyPay™ ETF | REGULATED INVESTMENT COMPANY TAX RISKS  
Prospectus [Line Items]  
Risk [Text Block]

REGULATED INVESTMENT COMPANY TAX RISKS. The Fund intends to qualify annually and to elect to be treated as a regulated investment company under the Internal Revenue Code of 1986, as amended (the “Code”). To qualify for the favorable U.S. federal income tax treatment generally accorded to regulated investment companies, the Fund must, among other things, (i) derive in each taxable year at least 90% of its gross income from dividends, interest, payments with respect to securities loans and gains from the sale or other disposition of stock, securities or foreign currencies or other income derived with respect to its business of investing in such stock, securities or currencies, or net income derived from interests in certain publicly traded partnerships; (ii) diversify its holdings so that, at the end of each quarter of the taxable year, (a) at least 50% of the market value of the Fund’s assets is represented by cash and cash items (including receivables), U.S. government securities, the securities of other regulated investment companies and other securities, with such other securities of any one issuer generally limited for the purposes of this calculation to an amount not greater than 5% of the value of the Fund’s total assets and not greater than 10% of the outstanding voting securities of such issuer, and (b) not more than 25% of the value of its total assets is invested in the securities (other than U.S. government securities or the securities of other regulated investment companies) of any one issuer, or two or more issuers which the Fund controls which are engaged in the same, similar or related trades or businesses, or the securities of one or more of certain publicly traded partnerships; and (iii) distribute at least 90% of its investment company taxable income (which includes, among other items, dividends, interest and net short-term capital gains in excess of net long-term capital losses) and at least 90% of its net tax-exempt interest income each taxable year. There are certain exceptions for failure to qualify if the failure is for reasonable cause or is de minimis, and certain corrective action is taken and certain tax payments are made by the Fund.

 

If the Fund were to fail to meet the qualifying income test or asset diversification test and fail to qualify as a RIC, it would be taxed in the same manner as an ordinary corporation, and distributions to its shareholders would not be deductible by the Fund in computing its taxable income, which would adversely affect the Fund’s performance.

Roundhill APP WeeklyPay™ ETF | LARGE SHAREHOLDER RISK  
Prospectus [Line Items]  
Risk [Text Block]

LARGE SHAREHOLDER RISK. Certain shareholders, including affiliated funds advised by the Adviser, may from time to time own a significant portion of the Fund’s shares. In addition, a third-party investor, the Adviser or an affiliate of the Adviser (“Affiliate”), an authorized participant, a market maker, or another entity may invest in the Fund and hold its investment for a limited period solely to facilitate the commencement of the Fund or to help the Fund achieve a specified size or scale. There can be no assurance that any large shareholder will not redeem its investment, that the size of the Fund will be maintained at such levels, or that the Fund will continue to meet applicable listing requirements. Redemptions by large shareholders could have a significant negative impact on the Fund. In addition, transactions by large shareholders may account for a large percentage of the trading volume on the Fund’s listing exchange and may, therefore, have a material upward or downward effect on the market price of the shares.

 

To the extent that a significant percentage of the Fund’s shares are owned or controlled by a small number of account shareholders (or a single account shareholder), including funds or accounts over which the Adviser or an Affiliate has investment discretion, the Fund is subject to the risk that those shareholders may purchase or redeem Fund shares in significant amounts rapidly or unexpectedly, including as a result of an asset allocation decision made by the Adviser or an Affiliate. This may adversely affect the Fund’s performance if the Adviser is forced to sell portfolio securities or invest cash when it would not otherwise choose to do so. Redemptions of a large number of shares may affect the liquidity of the Fund’s portfolio, increase the Fund’s transaction costs, and accelerate the realization of taxable income and/or gains. In addition, a large redemption could result in the Fund’s current expenses being allocated over a smaller asset base, leading to an increase in the Fund’s gross expense ratio. Large purchases of the Fund’s shares may also adversely affect the Fund’s performance to the extent that the Fund is delayed in investing new cash or otherwise maintains a larger cash position than it ordinarily would, particularly if the Fund accepts cash for an order for the purchase of creation units of the Fund’s shares.

Roundhill APP WeeklyPay™ ETF | APP INVESTING RISKS  
Prospectus [Line Items]  
Risk [Text Block]

APP INVESTING RISKS. The Fund will have significant exposure to APP through its investments in swap agreements that utilize APP as the reference asset. Accordingly, the Fund will subject to the risks of APP, set forth below.

 

APP ISSUER-SPECIFIC RISKS. Issuer-specific attributes may cause an investment held by the Fund to be more volatile than the market generally. The value of an individual security or particular type of security may be more volatile than the market as a whole and may perform differently from the value of the market as a whole. APP operates in the competitive mobile advertising and application development space, facing competition from other technology companies and platforms. APP derives a substantial portion of its revenue from a small number of customers and partners. The loss of one or more key clients or partners, or a reduction in their advertising spend, could materially affect the company’s financial performance. In addition, APP’s vertically integrated business model, which includes advertising platforms, mediation tools, and analytics services, may present actual or perceived conflicts of interest that could impact its relationships with third parties or draw regulatory scrutiny. A core component of APP’s growth strategy involves its proprietary AI-based optimization engine. The company’s financial prospects are closely tied to the continued performance and adoption of this platform. If this optimization engine fails to deliver expected results or is outperformed by competing technologies, APP’s competitive position and stock price could be adversely affected. Moreover, APP has also undergone a strategic pivot by divesting portions of its owned app portfolio to focus more heavily on its advertising technology business. The success of this transition is uncertain, and any failure to execute effectively may result in operational disruptions, reduced revenues, or investor skepticism about the company’s long-term profitability. There is also some skepticism around APP’s accounting practices, particularly with respect to the company’s true profitability, as well risk associated with APP’s divesture of its applications business to focus more on advertising technology; misrepresented profitability and revenue gap or underperformance of the company’s advertising business could both affect share value. Additionally, significant historical insider selling, totaling over $1.9 billion by executives including the CEO, may raise concerns regarding insider confidence in the company’s future performance.

 

INDIRECT INVESTMENT RISK. AppLovin Corporation is not affiliated with the Trust, the Fund, the Adviser, the Sub-Adviser or any affiliates thereof and is not involved with this offering in any way, and has no obligation to consider the Fund in taking any corporate actions that might affect the value of the Fund. The Trust, the Fund, the Adviser, the Sub-Adviser or any affiliate are not responsible for the performance of APP and make no representation as to the performance of APP. Investing in the Fund is not equivalent to investing in APP. Fund shareholders will not have voting rights or rights to receive dividends or other distributions or any other rights with respect to APP.

 

INFORMATION TECHNOLOGY COMPANIES RISK. Information technology companies face intense competition, both domestically and internationally, which may have an adverse effect on profit margins. Like other technology companies, information technology companies may have limited product lines, markets, financial resources or personnel. The products of information technology companies may face obsolescence due to rapid technological developments, frequent new product introduction, unpredictable changes in growth rates and competition for the services of qualified personnel. Companies in the information technology sector are heavily dependent on patent and intellectual property rights. The loss or impairment of these rights may adversely affect the profitability of these companies. Information technology companies are facing increased government and regulatory scrutiny and may be subject to adverse government or regulatory action.

 

LARGE CAPITALIZATION COMPANIES RISK. Large capitalization companies may be less able than smaller capitalization companies to adapt to changing market conditions. Large capitalization companies may be more mature and subject to more limited growth potential compared with smaller capitalization companies. During different market cycles, the performance of large capitalization companies has trailed the overall performance of the broader securities markets.

 

UNITED STATES RISK. Certain changes in the U.S. economy, such as when the U.S. economy weakens or when its financial markets decline, may have an adverse effect on the securities to which the Fund has exposure.

NON-DIVERSIFICATION RISK. As a “non-diversified” fund, the Fund may hold a smaller number of portfolio securities than many other funds. To the extent the Fund invests in a relatively small number of issuers, a decline in the market value of a particular security held by the Fund may affect its value more than if it invested in a larger number of issuers. The value of the Fund Shares may be more volatile than the values of shares of more diversified funds.

Roundhill ORCL WeeklyPay™ ETF | MARKET RISK  
Prospectus [Line Items]  
Risk [Text Block]

Market Risk. Market risk is the risk that a particular investment, or Fund Shares in general, may fall in value. Securities are subject to market fluctuations caused by real or perceived adverse economic, political, and regulatory factors or market developments, changes in interest rates, disruptions to trade, impositions of tariffs and perceived trends in securities prices. Fund Shares could decline in value or underperform other investments. In addition, local, regional or global events such as war, acts of terrorism, market manipulation, government defaults, government shutdowns, regulatory actions, political changes, diplomatic developments, the imposition of sanctions and other similar measures, spread of infectious diseases or other public health issues, recessions, natural disasters, or other events could have a significant negative impact on the Fund and its investments. Any of such circumstances could have a materially negative impact on the value of Fund Shares, the liquidity of an investment, and may result in increased market volatility. During any such events, Fund Shares may trade at increased premiums or discounts to their net asset value, the bid/ask spread on Fund Shares may widen and the returns on investment may fluctuate.

Roundhill ORCL WeeklyPay™ ETF | LIQUIDITY RISK  
Prospectus [Line Items]  
Risk [Text Block]

LIQUIDITY RISK. The market for swap agreements that reference ORCL shares may be subject to periods of illiquidity. During such times it may be difficult or impossible to buy or sell a position at the desired price. Market disruptions or volatility can also make it difficult to find a counterparty willing to transact at a reasonable price and sufficient size. Illiquid markets may cause losses, which could be significant. The large size of the positions which the Fund may acquire increases the risk of illiquidity, may make its positions more difficult to liquidate, and may increase the losses incurred while trying to do so. Such large positions also may impact the price of swap agreements on ORCL shares.

Roundhill ORCL WeeklyPay™ ETF | ACTIVE MANAGEMENT RISK  
Prospectus [Line Items]

ACTIVE MANAGEMENT RISK. The Fund is actively-managed and its performance reflects investment decisions that the Adviser and/or Sub-Adviser makes for the Fund. Such judgments about the Fund’s investments may prove to be incorrect. If the investments selected and the strategies employed by the Fund fail to produce the intended results, the Fund could underperform as compared to other funds with similar investment objectives and/or strategies, or could have negative returns.

Roundhill ORCL WeeklyPay™ ETF | ACTIVE MARKET RISK

ACTIVE MARKET RISK. Although Fund Shares are listed for trading on the Exchange, there can be no assurance that an active trading market for Fund Shares will develop or be maintained. Fund Shares trade on the Exchange at market prices that may be below, at or above the Fund’s net asset value. Securities, including Fund Shares, are subject to market fluctuations and liquidity constraints that may be caused by such factors as economic, political, or regulatory developments, changes in interest rates, and/or perceived trends in securities prices. Fund Shares could decline in value or underperform other investments.

CONCENTRATION RISK. The Fund is susceptible to an increased risk of loss, including losses due to adverse events that affect the Fund’s investments more than the market as a whole, to the extent that the Fund’s investments are concentrated in investments that provide exposure to ORCL and the industry to which it is assigned.

Roundhill ORCL WeeklyPay™ ETF | COUNTERPARTY RISK

COUNTERPARTY RISK. Fund transactions involving a counterparty are subject to the risk that the counterparty will not fulfill its obligation to the Fund. Counterparty risk may arise because of the counterparty’s financial condition (i.e., financial difficulties, bankruptcy, or insolvency), market activities and developments, or other reasons, whether foreseen or not. A counterparty’s inability to fulfill its obligation may result in significant financial loss to the Fund. The Fund may be unable to recover its investment from the counterparty or may obtain a limited recovery, and/or recovery may be delayed.

CREDIT RISK. An issuer or other obligated party of a debt security may be unable or unwilling to make dividend, interest and/or principal payments when due. In addition, the value of a debt security may decline because of concerns about the issuer’s ability or unwillingness to make such payments.

Roundhill ORCL WeeklyPay™ ETF | CURRENT MARKET CONDITIONS RISK  
Prospectus [Line Items]  
Risk [Text Block]

CURRENT MARKET CONDITIONS RISK. Current market conditions risk is the risk that a particular investment, or Fund Shares in general, may fall in value due to current market conditions. As a means to fight inflation, which remains at elevated levels, the Federal Reserve and certain foreign central banks have raised interest rates; however, the Federal Reserve has recently lowered interest rates and may continue to do so. U.S. regulators have proposed several changes to market and issuer regulations which would directly impact the Fund, and any regulatory changes could adversely impact the Fund’s ability to achieve its investment strategies or make certain investments. Recent and potential future bank failures could result in disruption to the broader banking industry or markets generally and reduce confidence in financial institutions and the economy as a whole, which may also heighten market volatility and reduce liquidity. Additionally, challenges in commercial real estate markets, including rising interest rates, declining valuations and increasing vacancies, could have a broader impact on financial markets. The ongoing adversarial political climate in the United States, as well as political and diplomatic events both domestic and abroad, have and may continue to have an adverse impact the U.S. regulatory landscape, markets and investor behavior, which could have a negative impact on the Fund’s investments and operations. The change in administration resulting from the 2024 United States national elections could result in significant impacts to international trade relations, tax and immigration policies, and other aspects of the national and international political and financial landscape, which could affect, among other things, inflation and the securities markets generally. Other unexpected political, regulatory and diplomatic events within the U.S. and abroad may affect investor and consumer confidence and may adversely impact financial markets and the broader economy. For example, ongoing armed conflicts between Russia and Ukraine in Europe and among Israel, Iran, Hamas and other militant groups in the Middle East, have caused and could continue to cause significant market disruptions and volatility within the markets in Russia, Europe, the Middle East and the United States. The hostilities and sanctions resulting from those hostilities have and could continue to have a significant impact on certain Fund investments as well as Fund performance and liquidity. The economies of the United States and its trading partners, as well as the financial markets generally, may be adversely impacted by trade disputes, including the imposition of tariffs, and other matters. For example, the United States has imposed trade barriers and restrictions on China. In addition, the Chinese government is engaged in a longstanding dispute with Taiwan, continually threatening an invasion. If the political climate between the United States and China does not improve or continues to deteriorate, if China were to attempt invading Taiwan, or if other geopolitical conflicts develop or worsen, economies, markets and individual securities may be adversely affected, and the value of the Fund’s assets may go down. A public health crisis and the ensuing policies enacted by governments and central banks may cause significant volatility and uncertainty in global financial markets, negatively impacting global growth prospects. As the COVID-19 global pandemic illustrated, such events may affect certain geographic regions, countries, sectors and industries more significantly than others. Advancements in technology may also adversely impact markets and the overall performance of the Fund. For instance, the economy may be significantly impacted by the advanced development and increased regulation of artificial intelligence. Additionally, cyber security breaches of both government and non-government entities could have negative impacts on infrastructure and the ability of such entities, including the Fund, to operate properly. These events, and any other future events, may adversely affect the prices and liquidity of the Fund’s portfolio investments and could result in disruptions in the trading markets.

Roundhill ORCL WeeklyPay™ ETF | CYBERSECURITY RISK

Risk [Text Block]

CYBERSECURITY RISK. Failures or breaches of the electronic systems of the Fund, the Fund’s adviser, sub-adviser, distributor and other service providers, market makers, Authorized Participants or the issuers of securities in which the Fund invests have the ability to cause disruptions, negatively impact the Fund’s business operations and/or potentially result in financial losses to the Fund and its shareholders. While the Fund has established business continuity plans and risk management systems seeking to address system breaches or failures, there are inherent limitations in such plans and systems. Furthermore, the Fund cannot control the cybersecurity plans and systems of the Fund’s other service providers, market makers, Authorized Participants or issuers of securities in which the Fund invests.

Roundhill ORCL WeeklyPay™ ETF | DEBT SECURITIES RISK  
Prospectus [Line Items]  
Risk [Text Block]

DEBT SECURITIES RISK. Investments in debt securities subject the holder to the credit risk of the issuer. Credit risk refers to the possibility that the issuer or other obligor of a security will not be able or willing to make payments of interest and principal when due. Generally, the value of debt securities will change inversely with changes in interest rates. To the extent that interest rates rise, certain underlying obligations may be paid off substantially slower than originally anticipated and the value of those securities may fall sharply. During periods of falling interest rates, the income received by the Fund may decline. If the principal on a debt security is prepaid before expected, the prepayments of principal may have to be reinvested in obligations paying interest at lower rates. Debt securities generally do not trade on a securities exchange making them generally less liquid and more difficult to value than common stock.

Roundhill ORCL WeeklyPay™ ETF | DERIVATIVES RISK  
Prospectus [Line Items]  
Risk [Text Block]

DERIVATIVES RISK. The use of derivative instruments involves risks different from, or possibly greater than, the risks associated with investing directly in securities and other traditional investments. These risks include: (i) the risk that the counterparty to a derivative transaction may not fulfill its contractual obligations; (ii) risk of mispricing or improper valuation; and (iii) the risk that changes in the value of the derivative may not correlate perfectly with the underlying asset. Derivative prices are highly volatile and may fluctuate substantially during a short period of time. Such prices are influenced by numerous factors that affect the markets, including, but not limited to: changing supply and demand relationships; government programs and policies; national and international political and economic events, changes in interest rates, inflation and deflation and changes in supply and demand relationships. Trading derivative instruments involves risks different from, or possibly greater than, the risks associated with investing directly in securities. Derivative contracts ordinarily have leverage inherent in their terms. The use of leverage may cause the Fund to liquidate portfolio positions when it would not be advantageous to do so in order to satisfy its obligations or to meet regulatory or contractual requirements for derivatives. The use of derivatives can magnify potential for gain or loss and, therefore, amplify the effects of market volatility on share price.

Roundhill ORCL WeeklyPay™ ETF | DISTRIBUTION TAX RISK  
Prospectus [Line Items]  
Risk [Text Block]

DISTRIBUTION TAX RISK. The Fund currently expects to make distributions on a weekly basis. Such frequent distributions may expose investors to increased tax liabilities. However, these distributions may exceed the Fund’s income and gains for the Fund’s taxable year. Distributions in excess of the Fund’s current and accumulated earnings and profits will be treated as a return of capital. A return of capital distribution generally will not be taxable but will reduce the shareholder’s cost basis and will result in a higher capital gain or lower capital loss when those Fund Shares on which the distribution was received are sold. Once a Fund shareholder’s cost basis is reduced to zero, further distributions will be treated as capital gain if the Fund shareholder holds Fund Shares as capital assets. Additionally, any capital returned through distributions will be distributed after payment of Fund fees and expenses. Because a portion of the Fund’s distributions may consist of return of capital, the Fund may not be an appropriate investment for investors who do not want their principal investment in the Fund to decrease over time or who do not wish to receive return of capital in a given period. In the event that a shareholder purchases Fund Shares shortly before a distribution by the Fund, the entire distribution may be taxable to the shareholder even though a portion of the distribution effectively represents a return of the purchase price.

Roundhill ORCL WeeklyPay™ ETF | ETF RISK  
Prospectus [Line Items]  
Risk [Text Block]

ETF RISK. The Fund may invest in ETFs. The value of an ETF held by the Fund will fluctuate over time based on fluctuations in the values of the assets held by the ETF, which may be affected by changes in general economic conditions, expectations for future growth and profits, interest rates and the supply and demand for those assets. When the Fund invests in an ETF, it will bear a proportionate share of the ETF’s expenses. Brokerage, tax and other expenses may negatively impact the performance of the ETF and, in turn, the value of the Fund Shares. An ETF that tracks an index may not exactly match the performance of the index due to cash drag, differences between the portfolio of the ETF and the components of the index, expenses and other factors.

Roundhill ORCL WeeklyPay™ ETF | INFLATION RISK  
Prospectus [Line Items]  
Risk [Text Block]

INFLATION RISK. Inflation risk is the risk that the value of assets or income from investments will be less in the future as inflation decreases the value of money. As inflation increases, the present value of the Fund’s assets and distributions may decline. This risk is more prevalent with respect to fixed income securities held by the Fund.

Roundhill ORCL WeeklyPay™ ETF | Interest Rate Risk [Member]  
Prospectus [Line Items]  
Risk [Text Block]

INTEREST RATE RISK. Interest rate risk is the risk that the value of the debt securities in the Fund’s portfolio will decline because of rising market interest rates. Interest rate risk is generally lower for shorter term debt securities and higher for longer-term debt securities. Duration is a reasonably accurate measure of a debt security’s price sensitivity to changes in interest rates and a common measure of interest rate risk. Duration measures a debt security’s expected life on a present value basis, taking into account the debt security’s yield, interest payments and final maturity. In general, duration represents the expected percentage change in the value of a security for an immediate 1% change in interest rates. For example, the price of a debt security with a three-year duration would be expected to drop by approximately 3% in response to a 1% increase in interest rates. Therefore, prices of debt securities with shorter durations tend to be less sensitive to interest rate changes than debt securities with longer durations. As the value of a debt security changes over time, so will its duration.

Roundhill ORCL WeeklyPay™ ETF | LEGISLATION AND LITIGATION RISK  
Prospectus [Line Items]  
Risk [Text Block]

LEGISLATION AND LITIGATION RISK. Legislation or litigation that affects the value of assets or securities held by the Fund may reduce the value of the Fund. From time to time, various legislative initiatives are proposed that may have a negative impact on certain assets or securities in which the Fund invests. In addition, litigation regarding any of the assets or securities owned by the Fund may negatively impact the value of the Shares. Such legislation or litigation may cause the Fund to lose value or may result in higher portfolio turnover if the Adviser determines to sell such a holding.

Roundhill ORCL WeeklyPay™ ETF | LEVERAGE RISK  
Prospectus [Line Items]  
Risk [Text Block]

LEVERAGE RISK. The Fund obtains investment exposure in excess of its net assets by utilizing leverage and may lose more money in market conditions that are adverse to its investment objectives than a fund that does not utilize leverage. An investment in the Fund is exposed to the risk that a decline in the weekly performance of shares of ORCL will be magnified. This means that an investment in the Fund will be reduced by an amount equal to 1.2% for every 1% weekly decline in the market value of the ORCL shares, not including the costs of financing leverage and other operating expenses, which would further reduce its value. The Fund could theoretically lose an amount greater than its net assets in the event the market value of ORCL shares decline more than 83.33% over a calendar week. Leverage will also have the effect of magnifying any differences in the Fund’s correlation with ORCL shares.

Roundhill ORCL WeeklyPay™ ETF | MONEY MARKET INSTRUMENTS RISK  
Prospectus [Line Items]  
Risk [Text Block]

MONEY MARKET INSTRUMENTS RISK. The value of money market instruments may be affected by changing interest rates and by changes in the credit ratings of the investments. If a significant amount of the Fund’s assets are invested in money market instruments, it will be more difficult for the Fund to achieve its investment objectives. An investment in a money market fund is not insured or guaranteed by the FDIC or any other government agency. It is possible to lose money by investing in a money market fund.

Roundhill ORCL WeeklyPay™ ETF | OPERATIONAL RISK  
Prospectus [Line Items]  
Risk [Text Block]

OPERATIONAL RISK. The Fund is subject to risks arising from various operational factors, including, but not limited to, human error, processing and communication errors, errors of the Fund’s service providers, counterparties or other third-parties, failed or inadequate processes and technology or systems failures. The Fund relies on third-parties for a range of services, including custody. Any delay or failure relating to engaging or maintaining such service providers may affect the Fund’s ability to meet its investment objectives. Although the Fund and the Adviser seek to reduce these operational risks through controls and procedures, there is no way to completely protect against such risks.

Roundhill ORCL WeeklyPay™ ETF | SPECIAL TAX RISK  
Prospectus [Line Items]  
Risk [Text Block]

SPECIAL TAX RISK. The Fund intends to qualify annually and to elect to be treated as a regulated investment company under the Internal Revenue Code of 1986, as amended (the “Code”). To qualify for the favorable U.S. federal income tax treatment generally accorded to regulated investment companies, the Fund must, among other things, (i) derive in each taxable year at least 90% of its gross income from dividends, interest, payments with respect to securities loans and gains from the sale or other disposition of stock, securities or foreign currencies or other income derived with respect to its business of investing in such stock, securities or currencies, or net income derived from interests in certain publicly traded partnerships; (ii) diversify its holdings so that, at the end of each quarter of the taxable year, (a) at least 50% of the market value of the Fund’s assets is represented by cash and cash items (including receivables), U.S. government securities, the securities of other regulated investment companies and other securities, with such other securities of any one issuer generally limited for the purposes of this calculation to an amount not greater than 5% of the value of the Fund’s total assets and not greater than 10% of the outstanding voting securities of such issuer, and (b) not more than 25% of the value of its total assets is invested in the securities (other than U.S. government securities or the securities of other regulated investment companies) of any one issuer, or two or more issuers which the Fund controls which are engaged in the same, similar or related trades or businesses, or the securities of one or more of certain publicly traded partnerships; and (iii) distribute at least 90% of its investment company taxable income (which includes, among other items, dividends, interest and net short-term capital gains in excess of net long-term capital losses) and at least 90% of its net tax-exempt interest income each taxable year. There are certain exceptions for failure to qualify if the failure is for reasonable cause or is de minimis, and certain corrective action is taken and certain tax payments are made by the Fund.

 

The authority with regard to swaps entered into by regulated investment companies is unclear both as to the qualification under the income test and the identification of the issuer under the diversification test. The Fund intends to take the position that because the swaps held by the Fund reference securities that the income on the swaps are “other income” from the Fund’s business of investing in stocks and securities. In addition, the Fund intends to manage its investments in the swaps so that neither the exposure to issuer of the referenced security nor the exposure to any one counterparty of the swaps will exceed 25% of the gross value of the Fund’s portfolio at the end of any quarter.

 

If the Fund were to fail to meet the qualifying income test or asset diversification test and fail to qualify as a RIC, it would be taxed in the same manner as an ordinary corporation, and distributions to its shareholders would not be deductible by the Fund in computing its taxable income, which would adversely affect the Fund’s performance.

Roundhill ORCL WeeklyPay™ ETF | STRUCTURAL ETF RISKS  
Prospectus [Line Items]  
Risk [Text Block]

STRUCTURAL ETF RISKS. The Fund is an ETF. Accordingly, it is subject to certain risks associated with its unique structure.

 

Market Participants Risk. Only an Authorized Participant may engage in creation or redemption transactions directly with the Fund, and none of those Authorized Participants is obligated to engage in creation and/or redemption transactions. The Fund has a limited number of institutions that may act as Authorized Participants on an agency basis (i.e., on behalf of other market participants). To the extent that Authorized Participants exit the business or are unable to proceed with creation or redemption orders with respect to the Fund and no other Authorized Participant is able to step forward to create or redeem, Fund Shares may be more likely to trade at a premium or discount to NAV and possibly face trading halts or delisting. The Fund may also rely on a small number of third-party market makers to provide a market for the purchase and sale of Fund Shares but such market makers are under no obligation to do so. Decisions by Authorized Participants or market makers to reduce their role or step away from these activities in times of market stress could inhibit the effectiveness of the arbitrage process in maintaining the relationship between the underlying values of the Fund’s portfolio securities and the Fund’s market price. Any trading halt or other problem relating to the trading activity of these market makers or any issues disrupting the Authorized Participants’ ability to proceed with creation and/or redemption orders could result in a dramatic change in the spread between the Fund’s net asset value and the price at which Fund Shares are trading on the Exchange, which could result in a decrease in value of Fund Shares. This reduced effectiveness could result in Fund Shares trading at a premium or discount to net asset value and also in greater than normal intraday bid-ask spreads Fund Shares.

 

Cash Transactions Risk. The Fund currently expects to effect a significant portion of its creations and redemptions for cash, rather than in-kind securities. Paying redemption proceeds in cash rather than through in-kind delivery of portfolio securities may require the Fund to dispose of or sell portfolio securities or other assets at an inopportune time to obtain the cash needed to meet redemption orders. This may cause the Fund to sell a security and recognize a capital gain or loss that might not have been incurred if it had made a redemption in-kind. As a result, the Fund may pay out higher or lower annual capital gains distributions than ETFs that redeem in-kind. The use of cash creations and redemptions may also cause the Fund’s Shares to trade in the market at greater bid-ask spreads or greater premiums or discounts to the Fund’s NAV. Furthermore, the Fund may not be able to execute cash transactions for creation and redemption purposes at the same price used to determine the Fund’s NAV. To the extent that the maximum additional charge for creation or redemption transactions is insufficient to cover the execution shortfall, the Fund’s performance could be negatively impacted.

 

Costs of Buying and Selling Fund Shares. Due to the costs of buying or selling Fund Shares, including brokerage commissions imposed by brokers and bid/ask spreads, frequent trading of Fund Shares may significantly reduce investment results and an investment in Fund Shares may not be advisable for investors who anticipate regularly making small investments.

 

Premium/Discount Risk. As with all ETFs, Fund Shares may be bought and sold in the secondary market at market prices. The trading prices of Fund Shares in the secondary market may differ from the Fund’s daily net asset value per share and there may be times when the market price of the shares is more than the net asset value per share (premium) or less than the net asset value per share (discount). If a shareholder purchases Fund Shares at a time when the market price is at a premium to the net asset value or sells Fund Shares at a time when the market price is at a discount to the net asset value, the shareholder may pay more for, or receive less than, the underlying value of the Fund Shares, respectively. This risk is heightened in times of market volatility or periods of steep market declines.

 

Trading Risks. Although Fund Shares are listed for trading on the Exchange and may be traded on U.S. exchanges other than the Exchange, there can be no assurance that Fund Shares will trade with any volume, or at all, on any stock exchange. In stressed market conditions, the liquidity of Fund Shares may begin to mirror the liquidity of the Fund’s underlying portfolio holdings, which can be significantly less liquid than Fund Shares. Trading in Fund Shares on the Exchange may be halted due to market conditions or for reasons that, in the view of the Exchange, make trading in Fund Shares inadvisable. In addition, trading in Fund Shares on the Exchange is subject to trading halts caused by extraordinary market volatility pursuant to the Exchange’s “circuit breaker” rules. There can be no assurance that the requirements of the Exchange necessary to maintain the listing of the Fund will continue to be met or will remain unchanged.

Roundhill ORCL WeeklyPay™ ETF | U.S. GOVERNMENT SECURITIES RISK  
Prospectus [Line Items]  
Risk [Text Block]

U.S. GOVERNMENT SECURITIES RISK. U.S. government securities are subject to interest rate risk but generally do not involve the credit risks associated with investments in other types of debt securities. As a result, the yields available from U.S. government securities are generally lower than the yields available from other debt securities. U.S. government securities are guaranteed only as to the timely payment of interest and the payment of principal when held to maturity.

Roundhill ORCL WeeklyPay™ ETF | VALUATION RISK  
Prospectus [Line Items]  
Risk [Text Block]

VALUATION RISK. The Fund may hold securities or other assets that may be valued on the basis of factors other than market quotations. This may occur because the asset or security does not trade on a centralized exchange, or in times of market turmoil or reduced liquidity. There are multiple methods that can be used to value a portfolio holding when market quotations are not readily available. The value established for any portfolio holding at a point in time might differ from what would be produced using a different methodology or if it had been priced using market quotations. Portfolio holdings that are valued using techniques other than market quotations, including “fair valued” assets or securities, may be subject to greater fluctuation in their valuations from one day to the next than if market quotations were used. In addition, there is no assurance that the Fund could sell or close out a portfolio position for the value established for it at any time, and it is possible that the Fund would incur a loss because a portfolio position is sold or closed out at a discount to the valuation established by the Fund at that time. The Fund’s ability to value investments may be impacted by technological issues or errors by pricing services or other third-party service providers.

Roundhill ORCL WeeklyPay™ ETF | EQUITY SECURITIES RISK  
Prospectus [Line Items]  
Risk [Text Block]

EQUITY SECURITIES RISK. Equity securities are subject to changes in value, and their values may be more volatile than those of other asset classes. Equity securities prices fluctuate for several reasons, including changes in investors’ perceptions of the financial condition of an issuer or the general condition of the relevant equity market, such as market volatility, or when political or economic events affecting an issuer occur. Common stock prices may be particularly sensitive to rising interest rates, as the cost of capital rises and borrowing costs increase. Common stocks generally subject their holders to more risks than preferred stocks and debt securities because common stockholders’ claims are subordinated to those of holders of preferred stocks and debt securities upon the bankruptcy of the issuer.

Roundhill ORCL WeeklyPay™ ETF | SWAP AGREEMENTS RISK  
Prospectus [Line Items]  
Risk [Text Block]

SWAP AGREEMENTS RISK. The Fund will utilize swap agreements to derive its exposure to shares of ORCL. Swap agreements may involve greater risks than direct investment in securities as they may be leveraged and are subject to credit risk, counterparty risk and valuation risk. A swap agreement could result in losses if the underlying reference or asset does not perform as anticipated. In addition, many swaps trade over-the-counter and may be considered illiquid. It may not be possible for the Fund to liquidate a swap position at an advantageous time or price, which may result in significant losses.

Roundhill ORCL WeeklyPay™ ETF | NEW FUND RISK

NEW FUND RISK. The Fund is a recently organized investment company with a limited operating history. As a result, prospective investors have a limited track record or history on which to base their investment decision.

Prospectus [Line Items]  
Risk [Text Block]

REGULATED INVESTMENT COMPANY TAX RISKS. The Fund intends to qualify annually and to elect to be treated as a regulated investment company under the Internal Revenue Code of 1986, as amended (the “Code”). To qualify for the favorable U.S. federal income tax treatment generally accorded to regulated investment companies, the Fund must, among other things, (i) derive in each taxable year at least 90% of its gross income from dividends, interest, payments with respect to securities loans and gains from the sale or other disposition of stock, securities or foreign currencies or other income derived with respect to its business of investing in such stock, securities or currencies, or net income derived from interests in certain publicly traded partnerships; (ii) diversify its holdings so that, at the end of each quarter of the taxable year, (a) at least 50% of the market value of the Fund’s assets is represented by cash and cash items (including receivables), U.S. government securities, the securities of other regulated investment companies and other securities, with such other securities of any one issuer generally limited for the purposes of this calculation to an amount not greater than 5% of the value of the Fund’s total assets and not greater than 10% of the outstanding voting securities of such issuer, and (b) not more than 25% of the value of its total assets is invested in the securities (other than U.S. government securities or the securities of other regulated investment companies) of any one issuer, or two or more issuers which the Fund controls which are engaged in the same, similar or related trades or businesses, or the securities of one or more of certain publicly traded partnerships; and (iii) distribute at least 90% of its investment company taxable income (which includes, among other items, dividends, interest and net short-term capital gains in excess of net long-term capital losses) and at least 90% of its net tax-exempt interest income each taxable year. There are certain exceptions for failure to qualify if the failure is for reasonable cause or is de minimis, and certain corrective action is taken and certain tax payments are made by the Fund.

 

If the Fund were to fail to meet the qualifying income test or asset diversification test and fail to qualify as a RIC, it would be taxed in the same manner as an ordinary corporation, and distributions to its shareholders would not be deductible by the Fund in computing its taxable income, which would adversely affect the Fund’s performance.

Roundhill ORCL WeeklyPay™ ETF | LARGE SHAREHOLDER RISK  
Prospectus [Line Items]  
Risk [Text Block]

LARGE SHAREHOLDER RISK. Certain shareholders, including affiliated funds advised by the Adviser, may from time to time own a significant portion of the Fund’s shares. In addition, a third-party investor, the Adviser or an affiliate of the Adviser (“Affiliate”), an authorized participant, a market maker, or another entity may invest in the Fund and hold its investment for a limited period solely to facilitate the commencement of the Fund or to help the Fund achieve a specified size or scale. There can be no assurance that any large shareholder will not redeem its investment, that the size of the Fund will be maintained at such levels, or that the Fund will continue to meet applicable listing requirements. Redemptions by large shareholders could have a significant negative impact on the Fund. In addition, transactions by large shareholders may account for a large percentage of the trading volume on the Fund’s listing exchange and may, therefore, have a material upward or downward effect on the market price of the shares.

 

To the extent that a significant percentage of the Fund’s shares are owned or controlled by a small number of account shareholders (or a single account shareholder), including funds or accounts over which the Adviser or an Affiliate has investment discretion, the Fund is subject to the risk that those shareholders may purchase or redeem Fund shares in significant amounts rapidly or unexpectedly, including as a result of an asset allocation decision made by the Adviser or an Affiliate. This may adversely affect the Fund’s performance if the Adviser is forced to sell portfolio securities or invest cash when it would not otherwise choose to do so. Redemptions of a large number of shares may affect the liquidity of the Fund’s portfolio, increase the Fund’s transaction costs, and accelerate the realization of taxable income and/or gains. In addition, a large redemption could result in the Fund’s current expenses being allocated over a smaller asset base, leading to an increase in the Fund’s gross expense ratio. Large purchases of the Fund’s shares may also adversely affect the Fund’s performance to the extent that the Fund is delayed in investing new cash or otherwise maintains a larger cash position than it ordinarily would, particularly if the Fund accepts cash for an order for the purchase of creation units of the Fund’s shares.

Roundhill ORCL WeeklyPay™ ETF | ORCL INVESTING RISKS  
Prospectus [Line Items]  
Risk [Text Block]

ORCL INVESTING RISKS. The Fund will have significant exposure to ORCL through its investments in swap agreements that utilize ORCL as the reference asset. Accordingly, the Fund will subject to the risks of ORCL, set forth below.

 

ORCL ISSUER-SPECIFIC RISKS. Issuer-specific attributes may cause an investment held by the Fund to be more volatile than the market generally. The value of an individual security or particular type of security may be more volatile than the market as a whole and may perform differently from the value of the market as a whole. ORCL faces significant competition from other technology companies in cloud computing and artificial intelligence (“AI”), database management, and enterprise software. Increased competition from major players in the industry, including Microsoft, Amazon Workspace, and Google, may lead to pricing pressure, reduced market share, and higher marketing or research and development expenses. ORCL is transitioning its business model from traditional on-premises software to cloud and AI-based services. Failure to successfully execute this transition, or slower-than-expected adoption by customers, could negatively impact growth and profitability, and success in cloud and AI depends heavily on its ability to rapidly build new data centers to meet customer demand. As a provider of cloud and enterprise software, ORCL is exposed to risks of cyberattacks, data breaches, and evolving data privacy regulations. Such incidents could result in financial losses, regulatory penalties, and reputational harm. ORCL operates globally and is subject to various laws and regulations, including antitrust, data privacy, and export controls. Changes in regulations or adverse legal outcomes could impact operations and financial results. ORCL also has a history of acquisitions. Failure to successfully integrate acquired businesses or realize expected synergies could negatively affect results.

 

INDIRECT INVESTMENT RISK. Oracle Corporation is not affiliated with the Trust, the Fund, the Adviser, the Sub-Adviser or any affiliates thereof and is not involved with this offering in any way, and has no obligation to consider the Fund in taking any corporate actions that might affect the value of the Fund. The Trust, the Fund, the Adviser, the Sub-Adviser or any affiliate are not responsible for the performance of ORCL and make no representation as to the performance of ORCL. Investing in the Fund is not equivalent to investing in ORCL. Fund shareholders will not have voting rights or rights to receive dividends or other distributions or any other rights with respect to ORCL.

 

INFORMATION TECHNOLOGY COMPANIES RISK. Information technology companies face intense competition, both domestically and internationally, which may have an adverse effect on profit margins. Like other technology companies, information technology companies may have limited product lines, markets, financial resources or personnel. The products of information technology companies may face obsolescence due to rapid technological developments, frequent new product introduction, unpredictable changes in growth rates and competition for the services of qualified personnel. Companies in the information technology sector are heavily dependent on patent and intellectual property rights. The loss or impairment of these rights may adversely affect the profitability of these companies. Information technology companies are facing increased government and regulatory scrutiny and may be subject to adverse government or regulatory action.

 

LARGE CAPITALIZATION COMPANIES RISK. Large capitalization companies may be less able than smaller capitalization companies to adapt to changing market conditions. Large capitalization companies may be more mature and subject to more limited growth potential compared with smaller capitalization companies. During different market cycles, the performance of large capitalization companies has trailed the overall performance of the broader securities markets.

 

UNITED STATES RISK. Certain changes in the U.S. economy, such as when the U.S. economy weakens or when its financial markets decline, may have an adverse effect on the securities to which the Fund has exposure.

NON-DIVERSIFICATION RISK. As a “non-diversified” fund, the Fund may hold a smaller number of portfolio securities than many other funds. To the extent the Fund invests in a relatively small number of issuers, a decline in the market value of a particular security held by the Fund may affect its value more than if it invested in a larger number of issuers. The value of the Fund Shares may be more volatile than the values of shares of more diversified funds.

Roundhill UNH WeeklyPay™ ETF | MARKET RISK  
Prospectus [Line Items]  
Risk [Text Block]

Market Risk. Market risk is the risk that a particular investment, or Fund Shares in general, may fall in value. Securities are subject to market fluctuations caused by real or perceived adverse economic, political, and regulatory factors or market developments, changes in interest rates, disruptions to trade, impositions of tariffs and perceived trends in securities prices. Fund Shares could decline in value or underperform other investments. In addition, local, regional or global events such as war, acts of terrorism, market manipulation, government defaults, government shutdowns, regulatory actions, political changes, diplomatic developments, the imposition of sanctions and other similar measures, spread of infectious diseases or other public health issues, recessions, natural disasters, or other events could have a significant negative impact on the Fund and its investments. Any of such circumstances could have a materially negative impact on the value of Fund Shares, the liquidity of an investment, and may result in increased market volatility. During any such events, Fund Shares may trade at increased premiums or discounts to their net asset value, the bid/ask spread on Fund Shares may widen and the returns on investment may fluctuate.

Roundhill UNH WeeklyPay™ ETF | LIQUIDITY RISK  
Prospectus [Line Items]  
Risk [Text Block]

LIQUIDITY RISK. The market for swap agreements that reference UNH shares may be subject to periods of illiquidity. During such times it may be difficult or impossible to buy or sell a position at the desired price. Market disruptions or volatility can also make it difficult to find a counterparty willing to transact at a reasonable price and sufficient size. Illiquid markets may cause losses, which could be significant. The large size of the positions which the Fund may acquire increases the risk of illiquidity, may make its positions more difficult to liquidate, and may increase the losses incurred while trying to do so. Such large positions also may impact the price of swap agreements on UNH shares.

Roundhill UNH WeeklyPay™ ETF | ACTIVE MANAGEMENT RISK

ACTIVE MANAGEMENT RISK. The Fund is actively-managed and its performance reflects investment decisions that the Adviser and/or Sub-Adviser makes for the Fund. Such judgments about the Fund’s investments may prove to be incorrect. If the investments selected and the strategies employed by the Fund fail to produce the intended results, the Fund could underperform as compared to other funds with similar investment objectives and/or strategies, or could have negative returns.

ACTIVE MARKET RISK. Although Fund Shares are listed for trading on the Exchange, there can be no assurance that an active trading market for Fund Shares will develop or be maintained. Fund Shares trade on the Exchange at market prices that may be below, at or above the Fund’s net asset value. Securities, including Fund Shares, are subject to market fluctuations and liquidity constraints that may be caused by such factors as economic, political, or regulatory developments, changes in interest rates, and/or perceived trends in securities prices. Fund Shares could decline in value or underperform other investments.

The Fund is susceptible to an increased risk of loss, including losses due to adverse events that affect the Fund’s investments more than the market as a whole, to the extent that the Fund’s investments are concentrated in investments that provide exposure to UNH and the industry to which it is assigned.

Risk [Text Block]

COUNTERPARTY RISK. Fund transactions involving a counterparty are subject to the risk that the counterparty will not fulfill its obligation to the Fund. Counterparty risk may arise because of the counterparty’s financial condition (i.e., financial difficulties, bankruptcy, or insolvency), market activities and developments, or other reasons, whether foreseen or not. A counterparty’s inability to fulfill its obligation may result in significant financial loss to the Fund. The Fund may be unable to recover its investment from the counterparty or may obtain a limited recovery, and/or recovery may be delayed.

CREDIT RISK. An issuer or other obligated party of a debt security may be unable or unwilling to make dividend, interest and/or principal payments when due. In addition, the value of a debt security may decline because of concerns about the issuer’s ability or unwillingness to make such payments.

Roundhill UNH WeeklyPay™ ETF | CURRENT MARKET CONDITIONS RISK  
Prospectus [Line Items]  
Risk [Text Block]

CURRENT MARKET CONDITIONS RISK. Current market conditions risk is the risk that a particular investment, or Fund Shares in general, may fall in value due to current market conditions. As a means to fight inflation, which remains at elevated levels, the Federal Reserve and certain foreign central banks have raised interest rates; however, the Federal Reserve has recently lowered interest rates and may continue to do so. U.S. regulators have proposed several changes to market and issuer regulations which would directly impact the Fund, and any regulatory changes could adversely impact the Fund’s ability to achieve its investment strategies or make certain investments. Recent and potential future bank failures could result in disruption to the broader banking industry or markets generally and reduce confidence in financial institutions and the economy as a whole, which may also heighten market volatility and reduce liquidity. Additionally, challenges in commercial real estate markets, including rising interest rates, declining valuations and increasing vacancies, could have a broader impact on financial markets. The ongoing adversarial political climate in the United States, as well as political and diplomatic events both domestic and abroad, have and may continue to have an adverse impact the U.S. regulatory landscape, markets and investor behavior, which could have a negative impact on the Fund’s investments and operations. The change in administration resulting from the 2024 United States national elections could result in significant impacts to international trade relations, tax and immigration policies, and other aspects of the national and international political and financial landscape, which could affect, among other things, inflation and the securities markets generally. Other unexpected political, regulatory and diplomatic events within the U.S. and abroad may affect investor and consumer confidence and may adversely impact financial markets and the broader economy. For example, ongoing armed conflicts between Russia and Ukraine in Europe and among Israel, Iran, Hamas and other militant groups in the Middle East, have caused and could continue to cause significant market disruptions and volatility within the markets in Russia, Europe, the Middle East and the United States. The hostilities and sanctions resulting from those hostilities have and could continue to have a significant impact on certain Fund investments as well as Fund performance and liquidity. The economies of the United States and its trading partners, as well as the financial markets generally, may be adversely impacted by trade disputes, including the imposition of tariffs, and other matters. For example, the United States has imposed trade barriers and restrictions on China. In addition, the Chinese government is engaged in a longstanding dispute with Taiwan, continually threatening an invasion. If the political climate between the United States and China does not improve or continues to deteriorate, if China were to attempt invading Taiwan, or if other geopolitical conflicts develop or worsen, economies, markets and individual securities may be adversely affected, and the value of the Fund’s assets may go down. A public health crisis and the ensuing policies enacted by governments and central banks may cause significant volatility and uncertainty in global financial markets, negatively impacting global growth prospects. As the COVID-19 global pandemic illustrated, such events may affect certain geographic regions, countries, sectors and industries more significantly than others. Advancements in technology may also adversely impact markets and the overall performance of the Fund. For instance, the economy may be significantly impacted by the advanced development and increased regulation of artificial intelligence. Additionally, cyber security breaches of both government and non-government entities could have negative impacts on infrastructure and the ability of such entities, including the Fund, to operate properly. These events, and any other future events, may adversely affect the prices and liquidity of the Fund’s portfolio investments and could result in disruptions in the trading markets.

Roundhill UNH WeeklyPay™ ETF | CYBERSECURITY RISK

Risk [Text Block]

CYBERSECURITY RISK. Failures or breaches of the electronic systems of the Fund, the Fund’s adviser, sub-adviser, distributor and other service providers, market makers, Authorized Participants or the issuers of securities in which the Fund invests have the ability to cause disruptions, negatively impact the Fund’s business operations and/or potentially result in financial losses to the Fund and its shareholders. While the Fund has established business continuity plans and risk management systems seeking to address system breaches or failures, there are inherent limitations in such plans and systems. Furthermore, the Fund cannot control the cybersecurity plans and systems of the Fund’s other service providers, market makers, Authorized Participants or issuers of securities in which the Fund invests.

Roundhill UNH WeeklyPay™ ETF | DEBT SECURITIES RISK  
Prospectus [Line Items]  
Risk [Text Block]

DEBT SECURITIES RISK. Investments in debt securities subject the holder to the credit risk of the issuer. Credit risk refers to the possibility that the issuer or other obligor of a security will not be able or willing to make payments of interest and principal when due. Generally, the value of debt securities will change inversely with changes in interest rates. To the extent that interest rates rise, certain underlying obligations may be paid off substantially slower than originally anticipated and the value of those securities may fall sharply. During periods of falling interest rates, the income received by the Fund may decline. If the principal on a debt security is prepaid before expected, the prepayments of principal may have to be reinvested in obligations paying interest at lower rates. Debt securities generally do not trade on a securities exchange making them generally less liquid and more difficult to value than common stock.

Roundhill UNH WeeklyPay™ ETF | DERIVATIVES RISK  
Prospectus [Line Items]  
Risk [Text Block]

DERIVATIVES RISK. The use of derivative instruments involves risks different from, or possibly greater than, the risks associated with investing directly in securities and other traditional investments. These risks include: (i) the risk that the counterparty to a derivative transaction may not fulfill its contractual obligations; (ii) risk of mispricing or improper valuation; and (iii) the risk that changes in the value of the derivative may not correlate perfectly with the underlying asset. Derivative prices are highly volatile and may fluctuate substantially during a short period of time. Such prices are influenced by numerous factors that affect the markets, including, but not limited to: changing supply and demand relationships; government programs and policies; national and international political and economic events, changes in interest rates, inflation and deflation and changes in supply and demand relationships. Trading derivative instruments involves risks different from, or possibly greater than, the risks associated with investing directly in securities. Derivative contracts ordinarily have leverage inherent in their terms. The use of leverage may cause the Fund to liquidate portfolio positions when it would not be advantageous to do so in order to satisfy its obligations or to meet regulatory or contractual requirements for derivatives. The use of derivatives can magnify potential for gain or loss and, therefore, amplify the effects of market volatility on share price.

Roundhill UNH WeeklyPay™ ETF | DISTRIBUTION TAX RISK  
Prospectus [Line Items]  
Risk [Text Block]

DISTRIBUTION TAX RISK. The Fund currently expects to make distributions on a weekly basis. Such frequent distributions may expose investors to increased tax liabilities. However, these distributions may exceed the Fund’s income and gains for the Fund’s taxable year. Distributions in excess of the Fund’s current and accumulated earnings and profits will be treated as a return of capital. A return of capital distribution generally will not be taxable but will reduce the shareholder’s cost basis and will result in a higher capital gain or lower capital loss when those Fund Shares on which the distribution was received are sold. Once a Fund shareholder’s cost basis is reduced to zero, further distributions will be treated as capital gain if the Fund shareholder holds Fund Shares as capital assets. Additionally, any capital returned through distributions will be distributed after payment of Fund fees and expenses. Because a portion of the Fund’s distributions may consist of return of capital, the Fund may not be an appropriate investment for investors who do not want their principal investment in the Fund to decrease over time or who do not wish to receive return of capital in a given period. In the event that a shareholder purchases Fund Shares shortly before a distribution by the Fund, the entire distribution may be taxable to the shareholder even though a portion of the distribution effectively represents a return of the purchase price.

Roundhill UNH WeeklyPay™ ETF | ETF RISK  
Prospectus [Line Items]  
Risk [Text Block]

ETF RISK. The Fund may invest in ETFs. The value of an ETF held by the Fund will fluctuate over time based on fluctuations in the values of the assets held by the ETF, which may be affected by changes in general economic conditions, expectations for future growth and profits, interest rates and the supply and demand for those assets. When the Fund invests in an ETF, it will bear a proportionate share of the ETF’s expenses. Brokerage, tax and other expenses may negatively impact the performance of the ETF and, in turn, the value of the Fund Shares. An ETF that tracks an index may not exactly match the performance of the index due to cash drag, differences between the portfolio of the ETF and the components of the index, expenses and other factors.

Roundhill UNH WeeklyPay™ ETF | INFLATION RISK  
Prospectus [Line Items]  
Risk [Text Block]

INFLATION RISK. Inflation risk is the risk that the value of assets or income from investments will be less in the future as inflation decreases the value of money. As inflation increases, the present value of the Fund’s assets and distributions may decline. This risk is more prevalent with respect to fixed income securities held by the Fund.

Roundhill UNH WeeklyPay™ ETF | Interest Rate Risk [Member]  
Prospectus [Line Items]  
Risk [Text Block]

INTEREST RATE RISK. Interest rate risk is the risk that the value of the debt securities in the Fund’s portfolio will decline because of rising market interest rates. Interest rate risk is generally lower for shorter term debt securities and higher for longer-term debt securities. Duration is a reasonably accurate measure of a debt security’s price sensitivity to changes in interest rates and a common measure of interest rate risk. Duration measures a debt security’s expected life on a present value basis, taking into account the debt security’s yield, interest payments and final maturity. In general, duration represents the expected percentage change in the value of a security for an immediate 1% change in interest rates. For example, the price of a debt security with a three-year duration would be expected to drop by approximately 3% in response to a 1% increase in interest rates. Therefore, prices of debt securities with shorter durations tend to be less sensitive to interest rate changes than debt securities with longer durations. As the value of a debt security changes over time, so will its duration.

Roundhill UNH WeeklyPay™ ETF | LEGISLATION AND LITIGATION RISK  
Prospectus [Line Items]  
Risk [Text Block]

LEGISLATION AND LITIGATION RISK. Legislation or litigation that affects the value of assets or securities held by the Fund may reduce the value of the Fund. From time to time, various legislative initiatives are proposed that may have a negative impact on certain assets or securities in which the Fund invests. In addition, litigation regarding any of the assets or securities owned by the Fund may negatively impact the value of the Shares. Such legislation or litigation may cause the Fund to lose value or may result in higher portfolio turnover if the Adviser determines to sell such a holding.

Roundhill UNH WeeklyPay™ ETF | LEVERAGE RISK  
Prospectus [Line Items]  
Risk [Text Block]

LEVERAGE RISK. The Fund obtains investment exposure in excess of its net assets by utilizing leverage and may lose more money in market conditions that are adverse to its investment objectives than a fund that does not utilize leverage. An investment in the Fund is exposed to the risk that a decline in the weekly performance of shares of UNH will be magnified. This means that an investment in the Fund will be reduced by an amount equal to 1.2% for every 1% weekly decline in the market value of the UNH shares, not including the costs of financing leverage and other operating expenses, which would further reduce its value. The Fund could theoretically lose an amount greater than its net assets in the event the market value of UNH shares decline more than 83.33% over a calendar week. Leverage will also have the effect of magnifying any differences in the Fund’s correlation with UNH shares.

Roundhill UNH WeeklyPay™ ETF | MONEY MARKET INSTRUMENTS RISK  
Prospectus [Line Items]  
Risk [Text Block]

MONEY MARKET INSTRUMENTS RISK. The value of money market instruments may be affected by changing interest rates and by changes in the credit ratings of the investments. If a significant amount of the Fund’s assets are invested in money market instruments, it will be more difficult for the Fund to achieve its investment objectives. An investment in a money market fund is not insured or guaranteed by the FDIC or any other government agency. It is possible to lose money by investing in a money market fund.

Roundhill UNH WeeklyPay™ ETF | OPERATIONAL RISK  
Prospectus [Line Items]  
Risk [Text Block]

OPERATIONAL RISK. The Fund is subject to risks arising from various operational factors, including, but not limited to, human error, processing and communication errors, errors of the Fund’s service providers, counterparties or other third-parties, failed or inadequate processes and technology or systems failures. The Fund relies on third-parties for a range of services, including custody. Any delay or failure relating to engaging or maintaining such service providers may affect the Fund’s ability to meet its investment objectives. Although the Fund and the Adviser seek to reduce these operational risks through controls and procedures, there is no way to completely protect against such risks.

Roundhill UNH WeeklyPay™ ETF | SPECIAL TAX RISK  
Prospectus [Line Items]  
Risk [Text Block]

SPECIAL TAX RISK. The Fund intends to qualify annually and to elect to be treated as a regulated investment company under the Internal Revenue Code of 1986, as amended (the “Code”). To qualify for the favorable U.S. federal income tax treatment generally accorded to regulated investment companies, the Fund must, among other things, (i) derive in each taxable year at least 90% of its gross income from dividends, interest, payments with respect to securities loans and gains from the sale or other disposition of stock, securities or foreign currencies or other income derived with respect to its business of investing in such stock, securities or currencies, or net income derived from interests in certain publicly traded partnerships; (ii) diversify its holdings so that, at the end of each quarter of the taxable year, (a) at least 50% of the market value of the Fund’s assets is represented by cash and cash items (including receivables), U.S. government securities, the securities of other regulated investment companies and other securities, with such other securities of any one issuer generally limited for the purposes of this calculation to an amount not greater than 5% of the value of the Fund’s total assets and not greater than 10% of the outstanding voting securities of such issuer, and (b) not more than 25% of the value of its total assets is invested in the securities (other than U.S. government securities or the securities of other regulated investment companies) of any one issuer, or two or more issuers which the Fund controls which are engaged in the same, similar or related trades or businesses, or the securities of one or more of certain publicly traded partnerships; and (iii) distribute at least 90% of its investment company taxable income (which includes, among other items, dividends, interest and net short-term capital gains in excess of net long-term capital losses) and at least 90% of its net tax-exempt interest income each taxable year. There are certain exceptions for failure to qualify if the failure is for reasonable cause or is de minimis, and certain corrective action is taken and certain tax payments are made by the Fund.

 

The authority with regard to swaps entered into by regulated investment companies is unclear both as to the qualification under the income test and the identification of the issuer under the diversification test. The Fund intends to take the position that because the swaps held by the Fund reference securities that the income on the swaps are “other income” from the Fund’s business of investing in stocks and securities. In addition, the Fund intends to manage its investments in the swaps so that neither the exposure to issuer of the referenced security nor the exposure to any one counterparty of the swaps will exceed 25% of the gross value of the Fund’s portfolio at the end of any quarter.

 

If the Fund were to fail to meet the qualifying income test or asset diversification test and fail to qualify as a RIC, it would be taxed in the same manner as an ordinary corporation, and distributions to its shareholders would not be deductible by the Fund in computing its taxable income, which would adversely affect the Fund’s performance.

Roundhill UNH WeeklyPay™ ETF | STRUCTURAL ETF RISKS  
Prospectus [Line Items]  
Risk [Text Block]

STRUCTURAL ETF RISKS. The Fund is an ETF. Accordingly, it is subject to certain risks associated with its unique structure.

 

Market Participants Risk. Only an Authorized Participant may engage in creation or redemption transactions directly with the Fund, and none of those Authorized Participants is obligated to engage in creation and/or redemption transactions. The Fund has a limited number of institutions that may act as Authorized Participants on an agency basis (i.e., on behalf of other market participants). To the extent that Authorized Participants exit the business or are unable to proceed with creation or redemption orders with respect to the Fund and no other Authorized Participant is able to step forward to create or redeem, Fund Shares may be more likely to trade at a premium or discount to NAV and possibly face trading halts or delisting. The Fund may also rely on a small number of third-party market makers to provide a market for the purchase and sale of Fund Shares but such market makers are under no obligation to do so. Decisions by Authorized Participants or market makers to reduce their role or step away from these activities in times of market stress could inhibit the effectiveness of the arbitrage process in maintaining the relationship between the underlying values of the Fund’s portfolio securities and the Fund’s market price. Any trading halt or other problem relating to the trading activity of these market makers or any issues disrupting the Authorized Participants’ ability to proceed with creation and/or redemption orders could result in a dramatic change in the spread between the Fund’s net asset value and the price at which Fund Shares are trading on the Exchange, which could result in a decrease in value of Fund Shares. This reduced effectiveness could result in Fund Shares trading at a premium or discount to net asset value and also in greater than normal intraday bid-ask spreads Fund Shares.

 

Cash Transactions Risk. The Fund currently expects to effect a significant portion of its creations and redemptions for cash, rather than in-kind securities. Paying redemption proceeds in cash rather than through in-kind delivery of portfolio securities may require the Fund to dispose of or sell portfolio securities or other assets at an inopportune time to obtain the cash needed to meet redemption orders. This may cause the Fund to sell a security and recognize a capital gain or loss that might not have been incurred if it had made a redemption in-kind. As a result, the Fund may pay out higher or lower annual capital gains distributions than ETFs that redeem in-kind. The use of cash creations and redemptions may also cause the Fund’s Shares to trade in the market at greater bid-ask spreads or greater premiums or discounts to the Fund’s NAV. Furthermore, the Fund may not be able to execute cash transactions for creation and redemption purposes at the same price used to determine the Fund’s NAV. To the extent that the maximum additional charge for creation or redemption transactions is insufficient to cover the execution shortfall, the Fund’s performance could be negatively impacted.

 

Costs of Buying and Selling Fund Shares. Due to the costs of buying or selling Fund Shares, including brokerage commissions imposed by brokers and bid/ask spreads, frequent trading of Fund Shares may significantly reduce investment results and an investment in Fund Shares may not be advisable for investors who anticipate regularly making small investments.

 

Premium/Discount Risk. As with all ETFs, Fund Shares may be bought and sold in the secondary market at market prices. The trading prices of Fund Shares in the secondary market may differ from the Fund’s daily net asset value per share and there may be times when the market price of the shares is more than the net asset value per share (premium) or less than the net asset value per share (discount). If a shareholder purchases Fund Shares at a time when the market price is at a premium to the net asset value or sells Fund Shares at a time when the market price is at a discount to the net asset value, the shareholder may pay more for, or receive less than, the underlying value of the Fund Shares, respectively. This risk is heightened in times of market volatility or periods of steep market declines.

 

Trading Risks. Although Fund Shares are listed for trading on the Exchange and may be traded on U.S. exchanges other than the Exchange, there can be no assurance that Fund Shares will trade with any volume, or at all, on any stock exchange. In stressed market conditions, the liquidity of Fund Shares may begin to mirror the liquidity of the Fund’s underlying portfolio holdings, which can be significantly less liquid than Fund Shares. Trading in Fund Shares on the Exchange may be halted due to market conditions or for reasons that, in the view of the Exchange, make trading in Fund Shares inadvisable. In addition, trading in Fund Shares on the Exchange is subject to trading halts caused by extraordinary market volatility pursuant to the Exchange’s “circuit breaker” rules. There can be no assurance that the requirements of the Exchange necessary to maintain the listing of the Fund will continue to be met or will remain unchanged.

Roundhill UNH WeeklyPay™ ETF | U.S. GOVERNMENT SECURITIES RISK  
Prospectus [Line Items]  
Risk [Text Block]

U.S. GOVERNMENT SECURITIES RISK. U.S. government securities are subject to interest rate risk but generally do not involve the credit risks associated with investments in other types of debt securities. As a result, the yields available from U.S. government securities are generally lower than the yields available from other debt securities. U.S. government securities are guaranteed only as to the timely payment of interest and the payment of principal when held to maturity.

Roundhill UNH WeeklyPay™ ETF | VALUATION RISK  
Prospectus [Line Items]  
Risk [Text Block]

VALUATION RISK. The Fund may hold securities or other assets that may be valued on the basis of factors other than market quotations. This may occur because the asset or security does not trade on a centralized exchange, or in times of market turmoil or reduced liquidity. There are multiple methods that can be used to value a portfolio holding when market quotations are not readily available. The value established for any portfolio holding at a point in time might differ from what would be produced using a different methodology or if it had been priced using market quotations. Portfolio holdings that are valued using techniques other than market quotations, including “fair valued” assets or securities, may be subject to greater fluctuation in their valuations from one day to the next than if market quotations were used. In addition, there is no assurance that the Fund could sell or close out a portfolio position for the value established for it at any time, and it is possible that the Fund would incur a loss because a portfolio position is sold or closed out at a discount to the valuation established by the Fund at that time. The Fund’s ability to value investments may be impacted by technological issues or errors by pricing services or other third-party service providers.

Roundhill UNH WeeklyPay™ ETF | EQUITY SECURITIES RISK  
Prospectus [Line Items]  
Risk [Text Block]

EQUITY SECURITIES RISK. Equity securities are subject to changes in value, and their values may be more volatile than those of other asset classes. Equity securities prices fluctuate for several reasons, including changes in investors’ perceptions of the financial condition of an issuer or the general condition of the relevant equity market, such as market volatility, or when political or economic events affecting an issuer occur. Common stock prices may be particularly sensitive to rising interest rates, as the cost of capital rises and borrowing costs increase. Common stocks generally subject their holders to more risks than preferred stocks and debt securities because common stockholders’ claims are subordinated to those of holders of preferred stocks and debt securities upon the bankruptcy of the issuer.

Roundhill UNH WeeklyPay™ ETF | SWAP AGREEMENTS RISK  
Prospectus [Line Items]  
Risk [Text Block]

SWAP AGREEMENTS RISK. The Fund will utilize swap agreements to derive its exposure to shares of UNH. Swap agreements may involve greater risks than direct investment in securities as they may be leveraged and are subject to credit risk, counterparty risk and valuation risk. A swap agreement could result in losses if the underlying reference or asset does not perform as anticipated. In addition, many swaps trade over-the-counter and may be considered illiquid. It may not be possible for the Fund to liquidate a swap position at an advantageous time or price, which may result in significant losses.

Roundhill UNH WeeklyPay™ ETF | NEW FUND RISK

Prospectus [Line Items]  
Risk [Text Block]

REGULATED INVESTMENT COMPANY TAX RISKS. The Fund intends to qualify annually and to elect to be treated as a regulated investment company under the Internal Revenue Code of 1986, as amended (the “Code”). To qualify for the favorable U.S. federal income tax treatment generally accorded to regulated investment companies, the Fund must, among other things, (i) derive in each taxable year at least 90% of its gross income from dividends, interest, payments with respect to securities loans and gains from the sale or other disposition of stock, securities or foreign currencies or other income derived with respect to its business of investing in such stock, securities or currencies, or net income derived from interests in certain publicly traded partnerships; (ii) diversify its holdings so that, at the end of each quarter of the taxable year, (a) at least 50% of the market value of the Fund’s assets is represented by cash and cash items (including receivables), U.S. government securities, the securities of other regulated investment companies and other securities, with such other securities of any one issuer generally limited for the purposes of this calculation to an amount not greater than 5% of the value of the Fund’s total assets and not greater than 10% of the outstanding voting securities of such issuer, and (b) not more than 25% of the value of its total assets is invested in the securities (other than U.S. government securities or the securities of other regulated investment companies) of any one issuer, or two or more issuers which the Fund controls which are engaged in the same, similar or related trades or businesses, or the securities of one or more of certain publicly traded partnerships; and (iii) distribute at least 90% of its investment company taxable income (which includes, among other items, dividends, interest and net short-term capital gains in excess of net long-term capital losses) and at least 90% of its net tax-exempt interest income each taxable year. There are certain exceptions for failure to qualify if the failure is for reasonable cause or is de minimis, and certain corrective action is taken and certain tax payments are made by the Fund.

 

If the Fund were to fail to meet the qualifying income test or asset diversification test and fail to qualify as a RIC, it would be taxed in the same manner as an ordinary corporation, and distributions to its shareholders would not be deductible by the Fund in computing its taxable income, which would adversely affect the Fund’s performance.

Roundhill UNH WeeklyPay™ ETF | LARGE SHAREHOLDER RISK  
Prospectus [Line Items]  
Risk [Text Block]

LARGE SHAREHOLDER RISK. Certain shareholders, including affiliated funds advised by the Adviser, may from time to time own a significant portion of the Fund’s shares. In addition, a third-party investor, the Adviser or an affiliate of the Adviser (“Affiliate”), an authorized participant, a market maker, or another entity may invest in the Fund and hold its investment for a limited period solely to facilitate the commencement of the Fund or to help the Fund achieve a specified size or scale. There can be no assurance that any large shareholder will not redeem its investment, that the size of the Fund will be maintained at such levels, or that the Fund will continue to meet applicable listing requirements. Redemptions by large shareholders could have a significant negative impact on the Fund. In addition, transactions by large shareholders may account for a large percentage of the trading volume on the Fund’s listing exchange and may, therefore, have a material upward or downward effect on the market price of the shares.

 

To the extent that a significant percentage of the Fund’s shares are owned or controlled by a small number of account shareholders (or a single account shareholder), including funds or accounts over which the Adviser or an Affiliate has investment discretion, the Fund is subject to the risk that those shareholders may purchase or redeem Fund shares in significant amounts rapidly or unexpectedly, including as a result of an asset allocation decision made by the Adviser or an Affiliate. This may adversely affect the Fund’s performance if the Adviser is forced to sell portfolio securities or invest cash when it would not otherwise choose to do so. Redemptions of a large number of shares may affect the liquidity of the Fund’s portfolio, increase the Fund’s transaction costs, and accelerate the realization of taxable income and/or gains. In addition, a large redemption could result in the Fund’s current expenses being allocated over a smaller asset base, leading to an increase in the Fund’s gross expense ratio. Large purchases of the Fund’s shares may also adversely affect the Fund’s performance to the extent that the Fund is delayed in investing new cash or otherwise maintains a larger cash position than it ordinarily would, particularly if the Fund accepts cash for an order for the purchase of creation units of the Fund’s shares.

Roundhill UNH WeeklyPay™ ETF | UNH INVESTING RISKS  
Prospectus [Line Items]  
Risk [Text Block]

UNH INVESTING RISKS. The Fund will have significant exposure to UNH through its investments in swap agreements that utilize UNH as the reference asset. Accordingly, the Fund will subject to the risks of UNH, set forth below.

 

UNH ISSUER-SPECIFIC RISKS. Issuer-specific attributes may cause an investment held by the Fund to be more volatile than the market generally. The value of an individual security or particular type of security may be more volatile than the market as a whole and may perform differently from the value of the market as a whole. UNH faces substantial competition from other health care and insurance providers, which could result in pricing pressures, reduced market share, and increased costs related to marketing or innovation. UNH is actively evolving its business model to incorporate new health care technologies and digital solutions. If UNH is unable to effectively implement these changes, or if customer adoption is slower than anticipated, growth and profitability could be adversely affected. As a major health care provider, UNH is exposed to risks related to cybersecurity, data breaches, and changing data privacy regulations, which could lead to financial losses, regulatory penalties, and reputational damage. Operating on a global scale, UNH is subject to various laws and regulations, including those related to health care, data privacy, and antitrust. The politically sensitive and fluid nature of the health care equipment & services industry further complicates policy and regulation within the health care equipment & services industry, which could affect profitability. For example, UNH has faced Department of Justice investigations relating to its billing practices and its anti-trust competitive practices. Further regulatory changes or unfavorable legal outcomes could impact UNH’s operations and financial performance. Additionally, UNH has a history of acquisitions, and failure to successfully integrate acquired businesses or achieve anticipated synergies could negatively affect results.

 

HEALTH CARE COMPANIES RISK. Health care companies, such as companies providing medical and health care goods and services, companies engaged in manufacturing medical equipment, supplies and pharmaceuticals, as well as operating health care facilities and the provision of managed health care, may be affected by government regulations and government health care programs, increases or decreases in the cost of medical products and services and product liability claims, among other factors. Many health care companies are heavily dependent on patent protection, and the expiration of a company’s patent may adversely affect that company’s profitability. Health care companies are also subject to competitive forces that may result in price discounting, may be thinly capitalized and susceptible to product obsolescence.

 

INDIRECT INVESTMENT RISK. UnitedHealth Group Incorporated is not affiliated with the Trust, the Fund, the Adviser, the Sub-Adviser or any affiliates thereof and is not involved with this offering in any way, and has no obligation to consider the Fund in taking any corporate actions that might affect the value of the Fund. The Trust, the Fund, the Adviser, the Sub-Adviser or any affiliate are not responsible for the performance of UNH and make no representation as to the performance of UNH. Investing in the Fund is not equivalent to investing in UNH. Fund shareholders will not have voting rights or rights to receive dividends or other distributions or any other rights with respect to UNH.

 

LARGE CAPITALIZATION COMPANIES RISK. Large capitalization companies may be less able than smaller capitalization companies to adapt to changing market conditions. Large capitalization companies may be more mature and subject to more limited growth potential compared with smaller capitalization companies. During different market cycles, the performance of large capitalization companies has trailed the overall performance of the broader securities markets.

 

UNITED STATES RISK. Certain changes in the U.S. economy, such as when the U.S. economy weakens or when its financial markets decline, may have an adverse effect on the securities to which the Fund has exposure.

The value of the Fund Shares may be more volatile than the values of shares of more diversified funds.

Market Risk. Market risk is the risk that a particular investment, or Fund Shares in general, may fall in value. Securities are subject to market fluctuations caused by real or perceived adverse economic, political, and regulatory factors or market developments, changes in interest rates, disruptions to trade, impositions of tariffs and perceived trends in securities prices. Fund Shares could decline in value or underperform other investments. In addition, local, regional or global events such as war, acts of terrorism, market manipulation, government defaults, government shutdowns, regulatory actions, political changes, diplomatic developments, the imposition of sanctions and other similar measures, spread of infectious diseases or other public health issues, recessions, natural disasters, or other events could have a significant negative impact on the Fund and its investments. Any of such circumstances could have a materially negative impact on the value of Fund Shares, the liquidity of an investment, and may result in increased market volatility. During any such events, Fund Shares may trade at increased premiums or discounts to their net asset value, the bid/ask spread on Fund Shares may widen and the returns on investment may fluctuate.

Roundhill WMT WeeklyPay™ ETF | LIQUIDITY RISK

Risk [Text Block]

LIQUIDITY RISK. The market for swap agreements that reference WMT shares may be subject to periods of illiquidity. During such times it may be difficult or impossible to buy or sell a position at the desired price. Market disruptions or volatility can also make it difficult to find a counterparty willing to transact at a reasonable price and sufficient size. Illiquid markets may cause losses, which could be significant. The large size of the positions which the Fund may acquire increases the risk of illiquidity, may make its positions more difficult to liquidate, and may increase the losses incurred while trying to do so. Such large positions also may impact the price of swap agreements on WMT shares.

Roundhill WMT WeeklyPay™ ETF | ACTIVE MANAGEMENT RISK

Risk [Text Block]

ACTIVE MANAGEMENT RISK. The Fund is actively-managed and its performance reflects investment decisions that the Adviser and/or Sub-Adviser makes for the Fund. Such judgments about the Fund’s investments may prove to be incorrect. If the investments selected and the strategies employed by the Fund fail to produce the intended results, the Fund could underperform as compared to other funds with similar investment objectives and/or strategies, or could have negative returns.

Roundhill WMT WeeklyPay™ ETF | ACTIVE MARKET RISK

Risk [Text Block]

ACTIVE MARKET RISK. Although Fund Shares are listed for trading on the Exchange, there can be no assurance that an active trading market for Fund Shares will develop or be maintained. Fund Shares trade on the Exchange at market prices that may be below, at or above the Fund’s net asset value. Securities, including Fund Shares, are subject to market fluctuations and liquidity constraints that may be caused by such factors as economic, political, or regulatory developments, changes in interest rates, and/or perceived trends in securities prices. Fund Shares could decline in value or underperform other investments.

Risk [Text Block]

CONCENTRATION RISK. The Fund is susceptible to an increased risk of loss, including losses due to adverse events that affect the Fund’s investments more than the market as a whole, to the extent that the Fund’s investments are concentrated in investments that provide exposure to WMT and the industry to which it is assigned.

Roundhill WMT WeeklyPay™ ETF | COUNTERPARTY RISK  
Prospectus [Line Items]  
Risk [Text Block]

COUNTERPARTY RISK. Fund transactions involving a counterparty are subject to the risk that the counterparty will not fulfill its obligation to the Fund. Counterparty risk may arise because of the counterparty’s financial condition (i.e., financial difficulties, bankruptcy, or insolvency), market activities and developments, or other reasons, whether foreseen or not. A counterparty’s inability to fulfill its obligation may result in significant financial loss to the Fund. The Fund may be unable to recover its investment from the counterparty or may obtain a limited recovery, and/or recovery may be delayed.

CREDIT RISK. An issuer or other obligated party of a debt security may be unable or unwilling to make dividend, interest and/or principal payments when due. In addition, the value of a debt security may decline because of concerns about the issuer’s ability or unwillingness to make such payments.

Roundhill WMT WeeklyPay™ ETF | CURRENT MARKET CONDITIONS RISK  
Prospectus [Line Items]  
Risk [Text Block]

CURRENT MARKET CONDITIONS RISK. Current market conditions risk is the risk that a particular investment, or Fund Shares in general, may fall in value due to current market conditions. As a means to fight inflation, which remains at elevated levels, the Federal Reserve and certain foreign central banks have raised interest rates; however, the Federal Reserve has recently lowered interest rates and may continue to do so. U.S. regulators have proposed several changes to market and issuer regulations which would directly impact the Fund, and any regulatory changes could adversely impact the Fund’s ability to achieve its investment strategies or make certain investments. Recent and potential future bank failures could result in disruption to the broader banking industry or markets generally and reduce confidence in financial institutions and the economy as a whole, which may also heighten market volatility and reduce liquidity. Additionally, challenges in commercial real estate markets, including rising interest rates, declining valuations and increasing vacancies, could have a broader impact on financial markets. The ongoing adversarial political climate in the United States, as well as political and diplomatic events both domestic and abroad, have and may continue to have an adverse impact the U.S. regulatory landscape, markets and investor behavior, which could have a negative impact on the Fund’s investments and operations. The change in administration resulting from the 2024 United States national elections could result in significant impacts to international trade relations, tax and immigration policies, and other aspects of the national and international political and financial landscape, which could affect, among other things, inflation and the securities markets generally. Other unexpected political, regulatory and diplomatic events within the U.S. and abroad may affect investor and consumer confidence and may adversely impact financial markets and the broader economy. For example, ongoing armed conflicts between Russia and Ukraine in Europe and among Israel, Iran, Hamas and other militant groups in the Middle East, have caused and could continue to cause significant market disruptions and volatility within the markets in Russia, Europe, the Middle East and the United States. The hostilities and sanctions resulting from those hostilities have and could continue to have a significant impact on certain Fund investments as well as Fund performance and liquidity. The economies of the United States and its trading partners, as well as the financial markets generally, may be adversely impacted by trade disputes, including the imposition of tariffs, and other matters. For example, the United States has imposed trade barriers and restrictions on China. In addition, the Chinese government is engaged in a longstanding dispute with Taiwan, continually threatening an invasion. If the political climate between the United States and China does not improve or continues to deteriorate, if China were to attempt invading Taiwan, or if other geopolitical conflicts develop or worsen, economies, markets and individual securities may be adversely affected, and the value of the Fund’s assets may go down. A public health crisis and the ensuing policies enacted by governments and central banks may cause significant volatility and uncertainty in global financial markets, negatively impacting global growth prospects. As the COVID-19 global pandemic illustrated, such events may affect certain geographic regions, countries, sectors and industries more significantly than others. Advancements in technology may also adversely impact markets and the overall performance of the Fund. For instance, the economy may be significantly impacted by the advanced development and increased regulation of artificial intelligence. Additionally, cyber security breaches of both government and non-government entities could have negative impacts on infrastructure and the ability of such entities, including the Fund, to operate properly. These events, and any other future events, may adversely affect the prices and liquidity of the Fund’s portfolio investments and could result in disruptions in the trading markets.

Roundhill WMT WeeklyPay™ ETF | CYBERSECURITY RISK  
Prospectus [Line Items]  
Risk [Text Block]

CYBERSECURITY RISK. Failures or breaches of the electronic systems of the Fund, the Fund’s adviser, sub-adviser, distributor and other service providers, market makers, Authorized Participants or the issuers of securities in which the Fund invests have the ability to cause disruptions, negatively impact the Fund’s business operations and/or potentially result in financial losses to the Fund and its shareholders. While the Fund has established business continuity plans and risk management systems seeking to address system breaches or failures, there are inherent limitations in such plans and systems. Furthermore, the Fund cannot control the cybersecurity plans and systems of the Fund’s other service providers, market makers, Authorized Participants or issuers of securities in which the Fund invests.

Roundhill WMT WeeklyPay™ ETF | DEBT SECURITIES RISK  
Prospectus [Line Items]  
Risk [Text Block]

DEBT SECURITIES RISK. Investments in debt securities subject the holder to the credit risk of the issuer. Credit risk refers to the possibility that the issuer or other obligor of a security will not be able or willing to make payments of interest and principal when due. Generally, the value of debt securities will change inversely with changes in interest rates. To the extent that interest rates rise, certain underlying obligations may be paid off substantially slower than originally anticipated and the value of those securities may fall sharply. During periods of falling interest rates, the income received by the Fund may decline. If the principal on a debt security is prepaid before expected, the prepayments of principal may have to be reinvested in obligations paying interest at lower rates. Debt securities generally do not trade on a securities exchange making them generally less liquid and more difficult to value than common stock.

Roundhill WMT WeeklyPay™ ETF | DERIVATIVES RISK  
Prospectus [Line Items]  
Risk [Text Block]

DERIVATIVES RISK. The use of derivative instruments involves risks different from, or possibly greater than, the risks associated with investing directly in securities and other traditional investments. These risks include: (i) the risk that the counterparty to a derivative transaction may not fulfill its contractual obligations; (ii) risk of mispricing or improper valuation; and (iii) the risk that changes in the value of the derivative may not correlate perfectly with the underlying asset. Derivative prices are highly volatile and may fluctuate substantially during a short period of time. Such prices are influenced by numerous factors that affect the markets, including, but not limited to: changing supply and demand relationships; government programs and policies; national and international political and economic events, changes in interest rates, inflation and deflation and changes in supply and demand relationships. Trading derivative instruments involves risks different from, or possibly greater than, the risks associated with investing directly in securities. Derivative contracts ordinarily have leverage inherent in their terms. The use of leverage may cause the Fund to liquidate portfolio positions when it would not be advantageous to do so in order to satisfy its obligations or to meet regulatory or contractual requirements for derivatives. The use of derivatives can magnify potential for gain or loss and, therefore, amplify the effects of market volatility on share price.

Roundhill WMT WeeklyPay™ ETF | DISTRIBUTION TAX RISK  
Prospectus [Line Items]  
Risk [Text Block]

DISTRIBUTION TAX RISK. The Fund currently expects to make distributions on a weekly basis. Such frequent distributions may expose investors to increased tax liabilities. However, these distributions may exceed the Fund’s income and gains for the Fund’s taxable year. Distributions in excess of the Fund’s current and accumulated earnings and profits will be treated as a return of capital. A return of capital distribution generally will not be taxable but will reduce the shareholder’s cost basis and will result in a higher capital gain or lower capital loss when those Fund Shares on which the distribution was received are sold. Once a Fund shareholder’s cost basis is reduced to zero, further distributions will be treated as capital gain if the Fund shareholder holds Fund Shares as capital assets. Additionally, any capital returned through distributions will be distributed after payment of Fund fees and expenses. Because a portion of the Fund’s distributions may consist of return of capital, the Fund may not be an appropriate investment for investors who do not want their principal investment in the Fund to decrease over time or who do not wish to receive return of capital in a given period. In the event that a shareholder purchases Fund Shares shortly before a distribution by the Fund, the entire distribution may be taxable to the shareholder even though a portion of the distribution effectively represents a return of the purchase price.

Roundhill WMT WeeklyPay™ ETF | ETF RISK  
Prospectus [Line Items]  
Risk [Text Block]

ETF RISK. The Fund may invest in ETFs. The value of an ETF held by the Fund will fluctuate over time based on fluctuations in the values of the assets held by the ETF, which may be affected by changes in general economic conditions, expectations for future growth and profits, interest rates and the supply and demand for those assets. When the Fund invests in an ETF, it will bear a proportionate share of the ETF’s expenses. Brokerage, tax and other expenses may negatively impact the performance of the ETF and, in turn, the value of the Fund Shares. An ETF that tracks an index may not exactly match the performance of the index due to cash drag, differences between the portfolio of the ETF and the components of the index, expenses and other factors.

Roundhill WMT WeeklyPay™ ETF | INFLATION RISK  
Prospectus [Line Items]  
Risk [Text Block]

INFLATION RISK. Inflation risk is the risk that the value of assets or income from investments will be less in the future as inflation decreases the value of money. As inflation increases, the present value of the Fund’s assets and distributions may decline. This risk is more prevalent with respect to fixed income securities held by the Fund.

Roundhill WMT WeeklyPay™ ETF | Interest Rate Risk [Member]  
Prospectus [Line Items]  
Risk [Text Block]

INTEREST RATE RISK. Interest rate risk is the risk that the value of the debt securities in the Fund’s portfolio will decline because of rising market interest rates. Interest rate risk is generally lower for shorter term debt securities and higher for longer-term debt securities. Duration is a reasonably accurate measure of a debt security’s price sensitivity to changes in interest rates and a common measure of interest rate risk. Duration measures a debt security’s expected life on a present value basis, taking into account the debt security’s yield, interest payments and final maturity. In general, duration represents the expected percentage change in the value of a security for an immediate 1% change in interest rates. For example, the price of a debt security with a three-year duration would be expected to drop by approximately 3% in response to a 1% increase in interest rates. Therefore, prices of debt securities with shorter durations tend to be less sensitive to interest rate changes than debt securities with longer durations. As the value of a debt security changes over time, so will its duration.

Roundhill WMT WeeklyPay™ ETF | LEGISLATION AND LITIGATION RISK  
Prospectus [Line Items]  
Risk [Text Block]

LEGISLATION AND LITIGATION RISK. Legislation or litigation that affects the value of assets or securities held by the Fund may reduce the value of the Fund. From time to time, various legislative initiatives are proposed that may have a negative impact on certain assets or securities in which the Fund invests. In addition, litigation regarding any of the assets or securities owned by the Fund may negatively impact the value of the Shares. Such legislation or litigation may cause the Fund to lose value or may result in higher portfolio turnover if the Adviser determines to sell such a holding.

Roundhill WMT WeeklyPay™ ETF | LEVERAGE RISK  
Prospectus [Line Items]  
Risk [Text Block]

LEVERAGE RISK. The Fund obtains investment exposure in excess of its net assets by utilizing leverage and may lose more money in market conditions that are adverse to its investment objectives than a fund that does not utilize leverage. An investment in the Fund is exposed to the risk that a decline in the weekly performance of shares of WMT will be magnified. This means that an investment in the Fund will be reduced by an amount equal to 1.2% for every 1% weekly decline in the market value of the WMT shares, not including the costs of financing leverage and other operating expenses, which would further reduce its value. The Fund could theoretically lose an amount greater than its net assets in the event the market value of WMT shares decline more than 83.33% over a calendar week. Leverage will also have the effect of magnifying any differences in the Fund’s correlation with WMT shares.

Roundhill WMT WeeklyPay™ ETF | MONEY MARKET INSTRUMENTS RISK  
Prospectus [Line Items]  
Risk [Text Block]

MONEY MARKET INSTRUMENTS RISK. The value of money market instruments may be affected by changing interest rates and by changes in the credit ratings of the investments. If a significant amount of the Fund’s assets are invested in money market instruments, it will be more difficult for the Fund to achieve its investment objectives. An investment in a money market fund is not insured or guaranteed by the FDIC or any other government agency. It is possible to lose money by investing in a money market fund.

Roundhill WMT WeeklyPay™ ETF | OPERATIONAL RISK  
Prospectus [Line Items]  
Risk [Text Block]

OPERATIONAL RISK. The Fund is subject to risks arising from various operational factors, including, but not limited to, human error, processing and communication errors, errors of the Fund’s service providers, counterparties or other third-parties, failed or inadequate processes and technology or systems failures. The Fund relies on third-parties for a range of services, including custody. Any delay or failure relating to engaging or maintaining such service providers may affect the Fund’s ability to meet its investment objectives. Although the Fund and the Adviser seek to reduce these operational risks through controls and procedures, there is no way to completely protect against such risks.

Roundhill WMT WeeklyPay™ ETF | SPECIAL TAX RISK  
Prospectus [Line Items]  
Risk [Text Block]

SPECIAL TAX RISK. The Fund intends to qualify annually and to elect to be treated as a regulated investment company under the Internal Revenue Code of 1986, as amended (the “Code”). To qualify for the favorable U.S. federal income tax treatment generally accorded to regulated investment companies, the Fund must, among other things, (i) derive in each taxable year at least 90% of its gross income from dividends, interest, payments with respect to securities loans and gains from the sale or other disposition of stock, securities or foreign currencies or other income derived with respect to its business of investing in such stock, securities or currencies, or net income derived from interests in certain publicly traded partnerships; (ii) diversify its holdings so that, at the end of each quarter of the taxable year, (a) at least 50% of the market value of the Fund’s assets is represented by cash and cash items (including receivables), U.S. government securities, the securities of other regulated investment companies and other securities, with such other securities of any one issuer generally limited for the purposes of this calculation to an amount not greater than 5% of the value of the Fund’s total assets and not greater than 10% of the outstanding voting securities of such issuer, and (b) not more than 25% of the value of its total assets is invested in the securities (other than U.S. government securities or the securities of other regulated investment companies) of any one issuer, or two or more issuers which the Fund controls which are engaged in the same, similar or related trades or businesses, or the securities of one or more of certain publicly traded partnerships; and (iii) distribute at least 90% of its investment company taxable income (which includes, among other items, dividends, interest and net short-term capital gains in excess of net long-term capital losses) and at least 90% of its net tax-exempt interest income each taxable year. There are certain exceptions for failure to qualify if the failure is for reasonable cause or is de minimis, and certain corrective action is taken and certain tax payments are made by the Fund.

 

The authority with regard to swaps entered into by regulated investment companies is unclear both as to the qualification under the income test and the identification of the issuer under the diversification test. The Fund intends to take the position that because the swaps held by the Fund reference securities that the income on the swaps are “other income” from the Fund’s business of investing in stocks and securities. In addition, the Fund intends to manage its investments in the swaps so that neither the exposure to issuer of the referenced security nor the exposure to any one counterparty of the swaps will exceed 25% of the gross value of the Fund’s portfolio at the end of any quarter.

 

If the Fund were to fail to meet the qualifying income test or asset diversification test and fail to qualify as a RIC, it would be taxed in the same manner as an ordinary corporation, and distributions to its shareholders would not be deductible by the Fund in computing its taxable income, which would adversely affect the Fund’s performance.

Roundhill WMT WeeklyPay™ ETF | STRUCTURAL ETF RISKS  
Prospectus [Line Items]  
Risk [Text Block]

STRUCTURAL ETF RISKS. The Fund is an ETF. Accordingly, it is subject to certain risks associated with its unique structure.

 

Market Participants Risk. Only an Authorized Participant may engage in creation or redemption transactions directly with the Fund, and none of those Authorized Participants is obligated to engage in creation and/or redemption transactions. The Fund has a limited number of institutions that may act as Authorized Participants on an agency basis (i.e., on behalf of other market participants). To the extent that Authorized Participants exit the business or are unable to proceed with creation or redemption orders with respect to the Fund and no other Authorized Participant is able to step forward to create or redeem, Fund Shares may be more likely to trade at a premium or discount to NAV and possibly face trading halts or delisting. The Fund may also rely on a small number of third-party market makers to provide a market for the purchase and sale of Fund Shares but such market makers are under no obligation to do so. Decisions by Authorized Participants or market makers to reduce their role or step away from these activities in times of market stress could inhibit the effectiveness of the arbitrage process in maintaining the relationship between the underlying values of the Fund’s portfolio securities and the Fund’s market price. Any trading halt or other problem relating to the trading activity of these market makers or any issues disrupting the Authorized Participants’ ability to proceed with creation and/or redemption orders could result in a dramatic change in the spread between the Fund’s net asset value and the price at which Fund Shares are trading on the Exchange, which could result in a decrease in value of Fund Shares. This reduced effectiveness could result in Fund Shares trading at a premium or discount to net asset value and also in greater than normal intraday bid-ask spreads Fund Shares.

 

Cash Transactions Risk. The Fund currently expects to effect a significant portion of its creations and redemptions for cash, rather than in-kind securities. Paying redemption proceeds in cash rather than through in-kind delivery of portfolio securities may require the Fund to dispose of or sell portfolio securities or other assets at an inopportune time to obtain the cash needed to meet redemption orders. This may cause the Fund to sell a security and recognize a capital gain or loss that might not have been incurred if it had made a redemption in-kind. As a result, the Fund may pay out higher or lower annual capital gains distributions than ETFs that redeem in-kind. The use of cash creations and redemptions may also cause the Fund’s Shares to trade in the market at greater bid-ask spreads or greater premiums or discounts to the Fund’s NAV. Furthermore, the Fund may not be able to execute cash transactions for creation and redemption purposes at the same price used to determine the Fund’s NAV. To the extent that the maximum additional charge for creation or redemption transactions is insufficient to cover the execution shortfall, the Fund’s performance could be negatively impacted.

 

Costs of Buying and Selling Fund Shares. Due to the costs of buying or selling Fund Shares, including brokerage commissions imposed by brokers and bid/ask spreads, frequent trading of Fund Shares may significantly reduce investment results and an investment in Fund Shares may not be advisable for investors who anticipate regularly making small investments.

 

Premium/Discount Risk. As with all ETFs, Fund Shares may be bought and sold in the secondary market at market prices. The trading prices of Fund Shares in the secondary market may differ from the Fund’s daily net asset value per share and there may be times when the market price of the shares is more than the net asset value per share (premium) or less than the net asset value per share (discount). If a shareholder purchases Fund Shares at a time when the market price is at a premium to the net asset value or sells Fund Shares at a time when the market price is at a discount to the net asset value, the shareholder may pay more for, or receive less than, the underlying value of the Fund Shares, respectively. This risk is heightened in times of market volatility or periods of steep market declines.

 

Trading Risks. Although Fund Shares are listed for trading on the Exchange and may be traded on U.S. exchanges other than the Exchange, there can be no assurance that Fund Shares will trade with any volume, or at all, on any stock exchange. In stressed market conditions, the liquidity of Fund Shares may begin to mirror the liquidity of the Fund’s underlying portfolio holdings, which can be significantly less liquid than Fund Shares. Trading in Fund Shares on the Exchange may be halted due to market conditions or for reasons that, in the view of the Exchange, make trading in Fund Shares inadvisable. In addition, trading in Fund Shares on the Exchange is subject to trading halts caused by extraordinary market volatility pursuant to the Exchange’s “circuit breaker” rules. There can be no assurance that the requirements of the Exchange necessary to maintain the listing of the Fund will continue to be met or will remain unchanged.

Roundhill WMT WeeklyPay™ ETF | U.S. GOVERNMENT SECURITIES RISK  
Prospectus [Line Items]  
Risk [Text Block]

U.S. GOVERNMENT SECURITIES RISK. U.S. government securities are subject to interest rate risk but generally do not involve the credit risks associated with investments in other types of debt securities. As a result, the yields available from U.S. government securities are generally lower than the yields available from other debt securities. U.S. government securities are guaranteed only as to the timely payment of interest and the payment of principal when held to maturity.

Roundhill WMT WeeklyPay™ ETF | VALUATION RISK  
Prospectus [Line Items]  
Risk [Text Block]

VALUATION RISK. The Fund may hold securities or other assets that may be valued on the basis of factors other than market quotations. This may occur because the asset or security does not trade on a centralized exchange, or in times of market turmoil or reduced liquidity. There are multiple methods that can be used to value a portfolio holding when market quotations are not readily available. The value established for any portfolio holding at a point in time might differ from what would be produced using a different methodology or if it had been priced using market quotations. Portfolio holdings that are valued using techniques other than market quotations, including “fair valued” assets or securities, may be subject to greater fluctuation in their valuations from one day to the next than if market quotations were used. In addition, there is no assurance that the Fund could sell or close out a portfolio position for the value established for it at any time, and it is possible that the Fund would incur a loss because a portfolio position is sold or closed out at a discount to the valuation established by the Fund at that time. The Fund’s ability to value investments may be impacted by technological issues or errors by pricing services or other third-party service providers.

Roundhill WMT WeeklyPay™ ETF | EQUITY SECURITIES RISK  
Prospectus [Line Items]  
Risk [Text Block]

EQUITY SECURITIES RISK. Equity securities are subject to changes in value, and their values may be more volatile than those of other asset classes. Equity securities prices fluctuate for several reasons, including changes in investors’ perceptions of the financial condition of an issuer or the general condition of the relevant equity market, such as market volatility, or when political or economic events affecting an issuer occur. Common stock prices may be particularly sensitive to rising interest rates, as the cost of capital rises and borrowing costs increase. Common stocks generally subject their holders to more risks than preferred stocks and debt securities because common stockholders’ claims are subordinated to those of holders of preferred stocks and debt securities upon the bankruptcy of the issuer.

Roundhill WMT WeeklyPay™ ETF | SWAP AGREEMENTS RISK  
Prospectus [Line Items]  
Risk [Text Block]

SWAP AGREEMENTS RISK. The Fund will utilize swap agreements to derive its exposure to shares of WMT. Swap agreements may involve greater risks than direct investment in securities as they may be leveraged and are subject to credit risk, counterparty risk and valuation risk. A swap agreement could result in losses if the underlying reference or asset does not perform as anticipated. In addition, many swaps trade over-the-counter and may be considered illiquid. It may not be possible for the Fund to liquidate a swap position at an advantageous time or price, which may result in significant losses.

Roundhill WMT WeeklyPay™ ETF | NEW FUND RISK

Prospectus [Line Items]  
Risk [Text Block]

REGULATED INVESTMENT COMPANY TAX RISKS. The Fund intends to qualify annually and to elect to be treated as a regulated investment company under the Internal Revenue Code of 1986, as amended (the “Code”). To qualify for the favorable U.S. federal income tax treatment generally accorded to regulated investment companies, the Fund must, among other things, (i) derive in each taxable year at least 90% of its gross income from dividends, interest, payments with respect to securities loans and gains from the sale or other disposition of stock, securities or foreign currencies or other income derived with respect to its business of investing in such stock, securities or currencies, or net income derived from interests in certain publicly traded partnerships; (ii) diversify its holdings so that, at the end of each quarter of the taxable year, (a) at least 50% of the market value of the Fund’s assets is represented by cash and cash items (including receivables), U.S. government securities, the securities of other regulated investment companies and other securities, with such other securities of any one issuer generally limited for the purposes of this calculation to an amount not greater than 5% of the value of the Fund’s total assets and not greater than 10% of the outstanding voting securities of such issuer, and (b) not more than 25% of the value of its total assets is invested in the securities (other than U.S. government securities or the securities of other regulated investment companies) of any one issuer, or two or more issuers which the Fund controls which are engaged in the same, similar or related trades or businesses, or the securities of one or more of certain publicly traded partnerships; and (iii) distribute at least 90% of its investment company taxable income (which includes, among other items, dividends, interest and net short-term capital gains in excess of net long-term capital losses) and at least 90% of its net tax-exempt interest income each taxable year. There are certain exceptions for failure to qualify if the failure is for reasonable cause or is de minimis, and certain corrective action is taken and certain tax payments are made by the Fund.

 

If the Fund were to fail to meet the qualifying income test or asset diversification test and fail to qualify as a RIC, it would be taxed in the same manner as an ordinary corporation, and distributions to its shareholders would not be deductible by the Fund in computing its taxable income, which would adversely affect the Fund’s performance.

Roundhill WMT WeeklyPay™ ETF | LARGE SHAREHOLDER RISK  
Prospectus [Line Items]  
Risk [Text Block]

LARGE SHAREHOLDER RISK. Certain shareholders, including affiliated funds advised by the Adviser, may from time to time own a significant portion of the Fund’s shares. In addition, a third-party investor, the Adviser or an affiliate of the Adviser (“Affiliate”), an authorized participant, a market maker, or another entity may invest in the Fund and hold its investment for a limited period solely to facilitate the commencement of the Fund or to help the Fund achieve a specified size or scale. There can be no assurance that any large shareholder will not redeem its investment, that the size of the Fund will be maintained at such levels, or that the Fund will continue to meet applicable listing requirements. Redemptions by large shareholders could have a significant negative impact on the Fund. In addition, transactions by large shareholders may account for a large percentage of the trading volume on the Fund’s listing exchange and may, therefore, have a material upward or downward effect on the market price of the shares.

 

To the extent that a significant percentage of the Fund’s shares are owned or controlled by a small number of account shareholders (or a single account shareholder), including funds or accounts over which the Adviser or an Affiliate has investment discretion, the Fund is subject to the risk that those shareholders may purchase or redeem Fund shares in significant amounts rapidly or unexpectedly, including as a result of an asset allocation decision made by the Adviser or an Affiliate. This may adversely affect the Fund’s performance if the Adviser is forced to sell portfolio securities or invest cash when it would not otherwise choose to do so. Redemptions of a large number of shares may affect the liquidity of the Fund’s portfolio, increase the Fund’s transaction costs, and accelerate the realization of taxable income and/or gains. In addition, a large redemption could result in the Fund’s current expenses being allocated over a smaller asset base, leading to an increase in the Fund’s gross expense ratio. Large purchases of the Fund’s shares may also adversely affect the Fund’s performance to the extent that the Fund is delayed in investing new cash or otherwise maintains a larger cash position than it ordinarily would, particularly if the Fund accepts cash for an order for the purchase of creation units of the Fund’s shares.

Roundhill WMT WeeklyPay™ ETF | WMT INVESTING RISKS  
Prospectus [Line Items]  
Risk [Text Block]

WMT INVESTING RISKS. The Fund will have significant exposure to WMT through its investments in swap agreements that utilize WMT as the reference asset. Accordingly, the Fund will subject to the risks of WMT, set forth below.

 

WMT ISSUER-SPECIFIC RISKS. Issuer-specific attributes may cause an investment held by the Fund to be more volatile than the market generally. The value of an individual security or particular type of security may be more volatile than the market as a whole and may perform differently from the value of the market as a whole. WMT faces significant competition in the retail sector from both traditional and online retailers which may result in pricing pressure, and reduced market share. Walmart also has a history of relatively low profit margins; changes in operating and supplier costs could impact overall profitability. WMT invests heavily in e-commerce and technology-driven initiatives; failure to successfully execute these strategies or slower-than-expected adoption by customers could negatively impact growth and profitability. As a global retailer, WMT is exposed to risks related to cyberattacks, data breaches, and evolving data privacy regulations, which could result in financial losses, regulatory penalties, and reputational harm. WMT operates internationally and is subject to a wide range of laws and regulations, including those related to antitrust, labor, and trade. Changes in regulations or adverse legal outcomes have may affect WMT’s operations and financial results. Additionally, WMT has a history of acquisitions; failure to successfully integrate acquired businesses or realize anticipated synergies could negatively impact its financial performance.

 

CONSUMER STAPLES COMPANIES RISK. Consumer staples companies provide products directly to the consumer that are typically considered non-discretionary items based on consumer purchasing habits. Such products include food, beverages, household items and tobacco. Companies providing these products may be affected by the regulation of various product components and production methods, new laws, regulations or litigation, marketing campaigns, competitive pricing, enumerated factors, consumer confidence, materials costs and other factors affecting consumer demand. Changes in the worldwide economy, demographics, consumer preferences, consumer spending, exploration and production spending may adversely affect these companies, as well as natural and man-made disasters, political, social or labor unrest, world events and economic conditions. Historically, the demand for consumer staples goods has remained fairly constant regardless of the state of the economy. With some products, such as food, alcohol and tobacco, demand sometimes increases during economic downturns. However, price competition among suppliers may be very challenging, which can drive prices lower and impact returns.

 

INDIRECT INVESTMENT RISK. Walmart Inc. is not affiliated with the Trust, the Fund, the Adviser, the Sub-Adviser or any affiliates thereof and is not involved with this offering in any way, and has no obligation to consider the Fund in taking any corporate actions that might affect the value of the Fund.

LARGE CAPITALIZATION COMPANIES RISK. Large capitalization companies may be less able than smaller capitalization companies to adapt to changing market conditions. Large capitalization companies may be more mature and subject to more limited growth potential compared with smaller capitalization companies. During different market cycles, the performance of large capitalization companies has trailed the overall performance of the broader securities markets.

 

UNITED STATES RISK. Certain changes in the U.S. economy, such as when the U.S. economy weakens or when its financial markets decline, may have an adverse effect on the securities to which the Fund has exposure.

NON-DIVERSIFICATION RISK. As a “non-diversified” fund, the Fund may hold a smaller number of portfolio securities than many other funds. To the extent the Fund invests in a relatively small number of issuers, a decline in the market value of a particular security held by the Fund may affect its value more than if it invested in a larger number of issuers. The value of the Fund Shares may be more volatile than the values of shares of more diversified funds.
