| Portfolio Turnover [Text Block] | rr_PortfolioTurnoverTextBlock | The Fund pays transaction costs, such as commissions, when it buys and sells securities (or “turns over” its portfolio). A higher portfolio turnover rate may indicate higher transaction costs and may result in higher taxes when Shares are held in a taxable account. These costs, which are not reflected in total annual fund operating expenses or in the expense example above, affect the Fund’s performance.
For the fiscal period September 13, 2023 (commencement of operations) to August 31, 2024, the Fund’s portfolio turnover rate was 9% of the average value of its portfolio.

| Strategy [Heading] | rr_StrategyHeading | Principal Investment Strategies | |||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||
| Strategy Narrative [Text Block] | rr_StrategyNarrativeTextBlock | The Fund is an actively managed exchange-traded fund (“ETF”) that seeks current income while maintaining the opportunity for indirect exposure to the value of the Index, subject to a limit on potential gains from increases in the value of the Index. More precisely, the Fund aims to generate additional income from its options investments when the Index rises in value, based on the specific put options it sold.
The Fund will seek to employ its investment strategy as it relates to the Index 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. As further described below, each day, the Fund uses an at-the-money and in-the-money put selling strategy to provide income and exposure to the value of the Index, subject to a limit on potential investment gains as a result of the nature of the options strategy it employs. The Fund’s options contracts provide current income from option premiums and a limit on the Fund’s indirect participation in gains, if any, of the increase in the value of the Index. In addition, the Fund’s in-the-money put options will provide some upside appreciation, also known as “intrinsic value.” As discussed in greater detail below, the Fund will not directly or fully participate in gains experienced by the Index. Please see “Additional Information about the Fund” below for a description of options terminology.
Every day, the Fund will sell put options that are priced either at-the-money or up to five percent in-the-money (i.e., higher than the current market price). If the Fund sells an option that’s priced above the current market price, the Fund may profit if the Index increases in value above its current price. This opportunity exists until the option’s expiration date, which is typically the next day (1DTE) or the same day (0DTE). This happens because an option priced above the current market value has a higher premium than an option priced at the current market value. In other words, the Fund’s potential for profit (or exposure) fluctuates. This potential for profit is calculated daily over a certain time period, but it’s also balanced out by any losses that might occur during that same period.
The Fund seeks to make monthly distributions. To enable it to do so, the Fund seeks to generate a consistent stream of income on a daily basis. In particular, the Fund sells in-the-money put options to seek a minimum daily income of 0.15%. If the Sub-Adviser determines this 0.15% daily income is not achievable, the Fund will sell options that are priced at the current market value to try to make the most of the available daily income. If the potential daily income exceeds 0.15%, then the Sub-Adviser will select a target strike to seek an equal mix of current and potential income.
The Fund seeks to provide an “enhanced” yield compared to traditional option-based strategies. It does this by frequently selling short-term options (typically less than one week in duration), which usually generates more income than selling longer-term options over the same period.
In addition to its options investments, the Fund will hold short-term U.S. Treasury securities for collateral for the options, and to generate income.
The Fund’s options contracts provide:
For more information, see the section “The Fund’s Use of Index Option Contracts” below.
The Fund’s investment adviser is Tidal Investments LLC (the “Adviser”) and the investment sub-adviser is ZEGA Financial, LLC (“ZEGA” or the “Sub-Adviser”).
Why invest in the Fund?
That is, although the Fund will not fully participate in gains in the value of the Index, the Fund’s portfolio is designed to generate income.
An Investment in the Fund is not an investment in the Index, nor is the Fund an investment in a traditional passively managed index fund.
Additional information regarding the Index is also set forth below.
The Fund’s Use of Index Option Contracts
Each day, the Fund will sell at-the-money and in-the-money puts on the Index (or on passively managed ETFs that seek to track the Index’s performance). In particular, the Fund will sell puts with near-term expirations at a range of 0% to 5% “in-the-money” (i.e., that is where the strike price is above the current value of the Index by between 0% and 5%). The Fund will receive premium income for each put sold. In addition, the strategy will provide the Fund with the opportunity to earn both time decay (described below) and, for in-the-money puts, a limited amount of upside appreciation up to the puts’ strike price (described below) plus the puts’ intrinsic value. The expiration dates at the time of purchase for the Fund’s sold puts will range from same day expiration to a week. The Fund’s participation in potential increases in the value of the Index is based on the level of the Index at the time the Fund sells a put option contract and the Index’s level at the time of the contract’s expiration.
For example, for simplicity, assume the Index is trading at 100 at the time the Fund sells an in-the-money put with a strike price of 105. If the Index’s level increases to 105 before expiration, the Fund would benefit from the increase in the Index’s value up to 105 through the receipt of the premium which was earned through the sale of the option. In addition, the Fund would benefit slightly from the in-the-money put’s extrinsic value. That is, if the Fund sold the put for 0.50% of time value (an amount paid above the put’s in-the-money value for the put’s potential to increase in value before expiration), the option in the example would earn up to 105.5. However, if the Index’s increase exceeded 105, the Fund would not participate in any of the additional upside.
Further, if the Index level drops below 100 at expiration minus an amount equal to the puts’ time value, the Fund would lose money. So, if the Fund sold the option for 0.50 of time value, the Fund would lose money if the Index fell below 99.5. The Fund would be obligated to cash settle the put option the difference between the strike price and the actual level of the Index, multiplied by the contract multiplier (usually 100 for equity index options).
The Fund seeks to make monthly distributions. To enable it to do so, the Fund seeks to generate a consistent stream of income on a daily basis. In particular, the Fund sells in-the-money put options to seek a minimum daily income of 0.15%. If the Sub-Adviser determines this 0.15% daily income is not achievable, the Fund will sell options that are priced at the current market value to try to make the most of the available daily income. If the potential daily income exceeds 0.15%, then the Sub-Adviser will select a target strike to seek an equal mix of current and potential income. Through this approach, the Fund seeks to provide an “enhanced” yield compared to traditional option-based strategies. It does this by frequently selling short-term options (typically less than one week in duration), which usually generates more income than selling longer-term options over the same period.
The Fund intends to invest only in cash-settled options, which means the holder of the option doesn’t receive securities when the option is exercised or expires. Instead, any payments are made in cash.
U.S. Treasuries
The Fund will hold short-term U.S. Treasury securities as collateral in connection with the Fund’s options strategy and to generate income.
Fund’s Monthly Distributions
The Fund will seek to provide monthly income in the form of cash distributions. The Fund will seek to generate such income in the following two ways:
Fund’s Return Profile vs the Index
For the reasons stated above, the Fund’s performance will differ from that of the Index’s value. The performance differences will depend on, among other things, the value of the Index, changes in the value of Index put options contracts the Fund has sold, and changes in the value of the U.S. Treasuries.
The Fund’s strategy is designed to have approximately a daily, unleveraged, 100% downside notional exposure to the Index. Essentially, the value of the put options that the Fund invests in will match the value as if the Fund had directly purchased the securities included in the Index.
Let’s consider a scenario where the Fund has assets totaling $10 million and the Index is priced at 5,000. In this instance, the number of contracts would be 20. We calculate this by dividing the Fund’s value by the value of one contract. Here, $10,000,000 divided by $500,000 (obtained by multiplying the index price of 5,000 by the standard multiplier of 100) gives us 20.
However, the Fund’s notional exposure will drift during each trading day. The Fund will reallocate its portfolio either during the day’s trading session (intraday) or at the end of each trading day. That is, the Fund will allow each day’s options to expire and then settle them in cash before entering into new put options. At times, the Fund may close out existing options positions and enter into new ones intraday. By settling expiring options in cash either intraday or at the end of the day, the Fund can seek to reduce execution costs and minimize trading drift.
Fund Portfolio
The Fund’s principal holdings are described below:
The market value of the cash and treasuries held by the Fund is expected to comprise at least 80% of the Fund’s net assets.
The Fund is classified as “non-diversified” under the Investment Company Act of 1940, as amended (the “1940 Act”).
Under normal circumstances, the Fund will invest at least 80% of the value of its net assets, plus borrowings for investment purposes, in financial instruments and economic interests that provide exposure to the value of the Index. For purposes of compliance with this investment policy, derivative contracts will be valued at their notional value.
There is no guarantee that the Fund’s investment strategy will be properly implemented, and an investor may lose some or all of its investment.
None of the Fund, the Trust, the Adviser, the Sub-Adviser, or their respective affiliates makes any representation to you as to the performance of the Index.
THE FUND, TRUST, ADVISER, AND SUB-ADVISER ARE NOT AFFILIATED WITH, NOR ENDORSED BY, THE INDEX.
Index Overview: The Nasdaq 100 Index is a benchmark index that includes 100 of the largest non-financial companies listed on the Nasdaq Stock Market, based on market capitalization. This makes it a large-cap index, meaning its constituents have a high market value, often in the billions of dollars.
The Index includes companies from various industries but is heavily weighted towards the technology sector. This reflects the Nasdaq’s historic strength as a listing venue for tech companies. Other sectors represented include consumer discretionary, health care, communication services, and industrials, among others.
In terms of volatility, like all stock indices, the Index experiences daily price movements and can be significantly volatile at times. This is often driven by macroeconomic factors, market sentiment, and financial results or news from its large constituents. Historical periods of significant volatility include the dot-com bubble burst around 2000 and the global financial crisis of 2007-2008, among other events. However, the specific degree of volatility can vary and is subject to change based on market conditions.

| Risk [Text Block] | rr_RiskTextBlock | The Nasdaq 100 Index Risks: The Index’s major risks stem from its high concentration in the technology sector and significant exposure to high-growth, high-valuation companies. A downturn in the tech industry, whether from regulatory changes, shifts in technology, or competitive pressures, can greatly impact the index. It’s also vulnerable to geopolitical risks due to many constituent companies having substantial international operations. Since many of these tech companies often trade at high valuations, a shift in investor sentiment could lead to significant price declines.

| Risk [Text Block] | rr_RiskTextBlock | Derivatives Risk. Derivatives are financial instruments that derive value from the underlying reference asset or assets, such as stocks, bonds, or funds (including ETFs), interest rates or indexes. The Fund’s investments in derivatives may pose risks in addition to, and greater than, those associated with directly investing in securities or other ordinary investments, including risk related to the market, imperfect correlation with underlying investments, higher price volatility, lack of availability, counterparty risk, liquidity, valuation and legal restrictions. The use of derivatives is a highly specialized activity that involves investment techniques and risks different from those associated with ordinary portfolio securities transactions. The use of derivatives may result in larger losses or smaller gains than directly investing in securities. When the Fund uses derivatives, there may be an imperfect correlation between the value of the Index and the derivative, which may prevent the Fund from achieving its investment objective. Because derivatives often require only a limited initial investment, the use of derivatives may expose the Fund to losses in excess of those amounts initially invested. In addition, the Fund’s investments in derivatives are subject to the following risks:

| Risk [Text Block] | rr_RiskTextBlock | Options Contracts. The use of options contracts involves investment strategies and risks different from those associated with ordinary portfolio securities transactions. The prices of options are volatile and are influenced by, among other things, actual and anticipated changes in the value of the underlying instrument, including the anticipated volatility, which are affected by fiscal and monetary policies and by national and international political, changes in the actual or implied volatility or the reference asset, the time remaining until the expiration of the option contract and economic events. For the Fund in particular, the value of the options contracts in which it invests are substantially influenced by the value of the Index. The Fund may experience substantial downside from specific option positions and certain option positions held by the Fund may expire worthless. The options held by the Fund are exercisable at the strike price on their expiration date. As an option approaches its expiration date, its value typically increasingly moves with the value of the underlying instrument. However, prior to such date, the value of an option generally does not increase or decrease at the same rate at the underlying instrument. There may at times be an imperfect correlation between the movement in values options contracts and the underlying instrument, and there may at times not be a liquid secondary market for certain options contracts. The value of the options held by the Fund will be determined based on market quotations or other recognized pricing methods.

| Prospectus [Line Items] | rr_ProspectusLineItems | ||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||
| Risk [Text Block] | rr_RiskTextBlock | Counterparty Risk. The Fund is subject to counterparty risk by virtue of its investments in options contracts. Transactions in some types of derivatives, including options, are required to be centrally cleared (“cleared derivatives”). In a transaction involving cleared derivatives, the Fund’s counterparty is a clearing house rather than a bank or broker. Since the Fund is not a member of clearing houses and only members of a clearing house (“clearing members”) can participate directly in the clearing house, the Fund will hold cleared derivatives through accounts at clearing members. In cleared derivatives positions, the Fund will make payments (including margin payments) to and receive payments from a clearing house through their accounts at clearing members. Customer funds held at a clearing organization in connection with any options 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 options 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 clearing house, there is a risk that the assets of the Fund might not be fully protected in the event of the clearing member’s bankruptcy, as the Fund would be limited to recovering only a pro rata share of all available funds segregated on behalf of the clearing member’s customers for the relevant account class. 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. 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.

| Prospectus [Line Items] | rr_ProspectusLineItems | ||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||
| Risk [Text Block] | rr_RiskTextBlock | Price Participation Risk. The Fund employs an investment strategy that includes the sale of in-the-money put option contracts, which limits the degree to which the Fund will participate in increases in value experienced by the Index over the Call Period (typically, one day, but may range up to one week). This means that if the Index experiences an increase in value above the strike price of the sold put options during a Call Period, the Fund will likely not experience that increase to the same extent and may significantly underperform the Index over the Call Period. Additionally, because the Fund is limited in the degree to which it will participate in increases in value experienced by the Index over each Call Period, but has full exposure to any decreases in value experienced by the Index over the Call Period, the NAV of the Fund may decrease over any given time period. The Fund’s NAV is dependent on the value of each options portfolio, which is based principally upon the performance of the Index. The degree of participation in the Index gains the Fund will experience will depend on prevailing market conditions, especially market volatility, at the time the Fund enters into the sold put option contracts and will vary from Call Period to Call Period. The value of the options contracts is affected by changes in the value and dividend rates of the Index, changes in interest rates, changes in the actual or perceived volatility of the Index and the remaining time to the options’ expiration, as well as trading conditions in the options market. As the price of the Index changes and time moves towards the expiration of each Call Period, the value of the options contracts, and therefore the Fund’s NAV, will change. However, it is not expected for the Fund’s NAV to directly correlate on a day-to-day basis with the returns of the Index. The amount of time remaining until the options contract’s expiration date affects the impact of the potential options contract income on the Fund’s NAV, which may not be in full effect until the expiration date of the Fund’s options contracts. Therefore, while changes in the price of the Index will result in changes to the Fund’s NAV, the Fund generally anticipates that the rate of change in the Fund’s NAV will be different than that experienced by the Index.

| Risk [Text Block] | rr_RiskTextBlock | Distribution Risk. As part of the Fund’s investment objective to provide current income, the Fund seeks to provide monthly income distributions. There is no assurance that the Fund will make a distribution in any given month. If the Fund does make distributions, the amounts of such distributions will likely vary greatly from one distribution to the next. Additionally, the monthly distributions, if any, may consist of returns of capital, which would decrease the Fund’s NAV and trading price over time. As a result, an investor may suffer significant losses to their investment.

| Risk [Text Block] | rr_RiskTextBlock | Put Writing Strategy Risk. The path dependency (i.e., the continued use) of the Fund’s put writing strategy will impact the extent that the Fund participates in the positive price returns of the Index and, in turn, the Fund’s returns, both during the term of the sold put options and over longer time periods.
If, for example, on a particular day, the Fund were to sell 1% in-the-money put options having a one-day term, the Fund’s participation in the positive price returns of the Index will be capped at 1% for that day. However, over a longer period (e.g., a five-day period), the Fund should not be expected to participate fully in the first 5% (i.e., 5 days x 1%) of the positive price returns of the Index, or the Fund may even lose money, even if the Index share price has appreciated by at least that much over such period, if during any particular day or days over that period the Index had a return less than 1%. This example illustrates that both the Fund’s participation in the positive price returns of the Index and its returns will depend not only on the price of the Index but also on the path that the Index takes over time.

To the extent either of the following events occur, Shares may trade at a material discount to NAV and possibly face delisting: (i) APs exit the business or otherwise become unable to process creation and/or redemption orders and no other APs step forward to perform these services; or (ii) market makers and/or liquidity providers exit the business or significantly reduce their business activities and no other entities step forward to perform their functions.

| Risk [Text Block] | rr_RiskTextBlock | Cash Redemption Risk. The Fund’s investment strategy may require it to redeem Shares for cash or to otherwise include cash as part of its redemption proceeds. For example, the Fund may not be able to redeem in-kind certain securities held by the Fund (e.g., derivative instruments). In such a case, the Fund may be required to sell or unwind portfolio investments to obtain the cash needed to distribute redemption proceeds. This may cause the Fund to recognize a capital gain that it might not have recognized if it had made a redemption in-kind. As a result, the Fund may pay out higher annual capital gain distributions than if the in-kind redemption process was used. By paying out higher annual capital gain distributions, investors may be subjected to increased capital gains taxes. Additionally, there may be brokerage costs or taxable gains or losses that may be imposed on the Fund in connection with a cash redemption that may not have occurred if the Fund had made a redemption in-kind. These costs could decrease the value of the Fund to the extent they are not offset by a transaction fee payable by an AP.

| Risk [Text Block] | rr_RiskTextBlock | Trading. Although Shares are listed on a national securities exchange, such as The Nasdaq Stock Market, LLC (the “Exchange”), and may be traded on U.S. exchanges other than the Exchange, there can be no assurance that an active trading market for the Shares will develop or be maintained or that the Shares will trade with any volume, or at all, on any stock exchange. This risk may be greater for the Fund as it seeks to have exposure to a single underlying stock as opposed to a more diverse portfolio like a traditional pooled investment. In stressed market conditions, the liquidity of Shares may begin to mirror the liquidity of the Fund’s underlying portfolio holdings, which can be significantly less liquid than Shares. Shares trade on the Exchange at a market price that may be below, at or above the Fund’s NAV. Trading in Shares on the Exchange may be halted due to market conditions or for reasons that, in the view of the Exchange, make trading in Shares inadvisable. In addition, trading in Shares on the Exchange is subject to trading halts caused by extraordinary market volatility pursuant to the Exchange “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. In the event of an unscheduled market close for options contracts that reference a single stock, such as the Index’s securities being halted or a market wide closure, settlement prices will be determined by the procedures of the listing exchange of the options contracts. As a result, the Fund could be adversely affected and be unable to implement its investment strategies in the event of an unscheduled closing.

| Risk [Text Block] | rr_RiskTextBlock | Liquidity Risk. Some securities held by the Fund, including options contracts, may be difficult to sell or be illiquid, particularly during times of market turmoil. This risk is greater for the Fund as it will hold options contracts on a single security, and not a broader range of options contracts. Markets for securities or financial instruments could be disrupted by a number of events, including, but not limited to, an economic crisis, natural disasters, epidemics/pandemics, new legislation or regulatory changes inside or outside the United States. Illiquid securities may be difficult to value, especially in changing or volatile markets. If the Fund is forced to sell an illiquid security at an unfavorable time or price, the Fund may be adversely impacted. Certain market conditions or restrictions, such as market rules related to short sales, may prevent the Fund from limiting losses, realizing gains or achieving a high correlation with the Index. There is no assurance that a security that is deemed liquid when purchased will continue to be liquid. Market illiquidity may cause losses for the Fund.

The Fund’s investments are subject to changes in general economic conditions, general market fluctuations and the risks inherent in investment in securities and other financial instruments. Investment markets can be volatile and prices of investments can change substantially due to various factors including, but not limited to, economic growth or recession, changes in interest rates, inflation, changes in the actual or perceived creditworthiness of issuers, and general market liquidity. The Fund is subject to the risk that geopolitical events will disrupt securities and other financial markets and adversely affect global economies and markets. Local, regional or global events such as war, military conflicts, acts of terrorism, natural disasters, the spread of infectious illness or other public health issues, or other events could have a significant impact on the Fund and its investments. Continuing uncertainties regarding interest rates, rising inflation, political events, rising government debt in the U.S. and trade tensions also contribute to market volatility. Conflict, loss of life and disaster connected to ongoing armed conflict between Ukraine and Russia in Europe and between Israel and Hamas in the Middle East could have severe adverse effects on the related region, including significant adverse effects on the regional or global economies and the markets for certain securities. The U.S. and the European Union have imposed sanctions on certain Russian individuals and companies, including certain financial institutions, and have limited certain exports and imports to and from Russia. These conflicts have contributed to recent market volatility and may continue to do so.

Because the Fund is “non-diversified,” it may invest a greater percentage of its assets in the securities of a single issuer or a smaller number of issuers than if it was a diversified fund. As a result, a decline in the value of an investment in a single issuer or a smaller number of issuers could cause the Fund’s overall value to decline to a greater degree than if the Fund held a more diversified portfolio. This may increase the Fund’s volatility and cause the performance of a relatively smaller number of issuers to have a greater impact on the Fund’s performance.

| Strategy [Heading] | rr_StrategyHeading | Principal Investment Strategies | |||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||
| Strategy Narrative [Text Block] | rr_StrategyNarrativeTextBlock | The Fund is an actively managed exchange-traded fund (“ETF”) that seeks current income while maintaining the opportunity for indirect exposure to the value of the Index, subject to a limit on potential gains from increases in the value of the Index. More precisely, the Fund aims to generate additional income from its options investments when the Index rises in value, based on the specific put options it sold.
The Fund will seek to employ its investment strategy as it relates to the Index 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. As further described below, each day, the Fund uses an at-the-money and in-the-money put selling strategy to provide income and exposure to the value of the Index, subject to a limit on potential investment gains as a result of the nature of the options strategy it employs. The Fund’s options contracts provide current income from option premiums and a limit on the Fund’s indirect participation in gains, if any, of the increase in the value of the Index. In addition, the Fund’s in-the-money put options will provide some upside appreciation, also known as “intrinsic value.” As discussed in greater detail below, the Fund will not directly or fully participate in gains experienced by the Index. Please see “Additional Information about the Fund” below for a description of options terminology.
Every day, the Fund will sell put options that are priced either at-the-money or up to five percent in-the-money (i.e., higher than the current market price). If the Fund sells an option that’s priced above the current market price, the Fund may profit if the Index increases in value above its current price. This opportunity exists until the option’s expiration date, which is typically the next day (1DTE) or the same day (0DTE). This happens because an option priced above the current market value has a higher premium than an option priced at the current market value. In other words, the Fund’s potential for profit (or exposure) fluctuates. This potential for profit is calculated daily over a certain time period, but it’s also balanced out by any losses that might occur during that same period.
The Fund seeks to make monthly distributions. To enable it to do so, the Fund seeks to generate a consistent stream of income on a daily basis. In particular, the Fund sells in-the-money put options to seek a minimum daily income of 0.15%. If the Sub-Adviser determines this 0.15% daily income is not achievable, the Fund will sell options that are priced at the current market value to try to make the most of the available daily income. If the potential daily income exceeds 0.15%, then the Sub-Adviser will select a target strike to seek an equal mix of current and potential income.
The Fund seeks to provide an “enhanced” yield compared to traditional option-based strategies. It does this by frequently selling short-term options (typically less than one week in duration), which usually generates more income than selling longer-term options over the same period.
In addition to its options investments, the Fund will hold short-term U.S. Treasury securities for collateral for the options, and to generate income.
The Fund’s options contracts provide:
For more information, see the section “The Fund’s Use of Index Option Contracts” below.
The Fund’s investment adviser is Tidal Investments, LLC (the “Adviser”) and the investment sub-adviser is ZEGA Financial, LLC (“ZEGA” or the “Sub-Adviser”).
Why invest in the Fund?
That is, although the Fund will not fully participate in gains in the value of the Index, the Fund’s portfolio is designed to generate income.
An Investment in the Fund is not an investment in the Index, nor is the Fund an investment in a traditional passively managed index fund.
Additional information regarding the Index is also set forth below.
The Fund’s Use of Index Option Contracts
Each day, the Fund will sell at-the-money and in-the-money puts on the Index (or on passively managed ETFs that seek to track the Index’s performance). In particular, the Fund will sell puts with near-term expirations at a range of 0% to 5% “in-the-money” (i.e., that is where the strike price is above the current value of the Index by between 0% and 5%). The Fund will receive premium income for each put sold. In addition, the strategy will provide the Fund with the opportunity to earn both time decay (described below) and, for in-the-money puts, a limited amount of upside appreciation up to the puts’ strike price (described below) plus the puts’ intrinsic value. The expiration dates at the time of purchase for the Fund’s sold puts will range from same day expiration to a week. The Fund’s participation in potential increases in the value of the Index is based on the level of the Index at the time the Fund sells a put option contract and the Index’s level at the time of the contract’s expiration.
For example, for simplicity, assume the Index is trading at 100 at the time the Fund sells an in-the-money put with a strike price of 105. If the Index’s level increases to 105 before expiration, the Fund would benefit from the increase in the Index’s value up to 105 through the receipt of the premium which was earned through the sale of the option. In addition, the Fund would benefit slightly from the in-the-money put’s extrinsic value. That is, if the Fund sold the put for 0.50% of time value (an amount paid above the put’s in the money value for the put’s potential to increase in value before expiration), the option in the example would earn up to 105.5. However, if the Index’s increase exceeded 105, the Fund would not participate in any of the additional upside.
Further, if the Index level drops below 100 at expiration minus an amount equal to the puts’ time value, the Fund would lose money. So, if the Fund sold the option for 0.50 of time value, the Fund would lose money if the Index fell below 99.5. The Fund would be obligated to cash settle the put option the difference between the strike price and the actual level of the Index, multiplied by the contract multiplier (usually 100 for equity index options).
The Fund seeks to make monthly distributions. To enable it to do so, the Fund seeks to generate a consistent stream of income on a daily basis. In particular, the Fund sells in-the-money put options to seek a minimum daily income of 0.15%. If the Sub-Adviser determines this 0.15% daily income is not achievable, the Fund will sell options that are priced at the current market value to try to make the most of the available daily income. If the potential daily income exceeds 0.15%, then the Sub-Adviser will select a target strike to seek an equal mix of current and potential income. Through this approach, the Fund seeks to provide an “enhanced” yield compared to traditional option-based strategies. It does this by frequently selling short-term options (typically less than one week in duration), which usually generates more income than selling longer-term options over the same period.
The Fund intends to invest only in cash-settled options, which means the holder of the option doesn’t receive securities when the option is exercised or expires. Instead, any payments are made in cash.
U.S. Treasuries
The Fund will hold short-term U.S. Treasury securities as collateral in connection with the Fund’s options strategy and to generate income.
Fund’s Monthly Distributions
The Fund will seek to provide monthly income in the form of cash distributions. The Fund will seek to generate such income in the following two ways:
Fund’s Return Profile vs the Index
For the reasons stated above, the Fund’s performance will differ from that of the Index’s value. The performance differences will depend on, among other things, the value of the Index, changes in the value of Index put options contracts the Fund has sold, and changes in the value of the U.S. Treasuries.
The Fund’s strategy is designed to have approximately a daily, unleveraged, 100% notional exposure to the Index. Essentially, the worth of the put options that the Fund invests in will match the value as if the Fund had directly purchased the securities included in the Index.
Let’s consider a scenario where the Fund has assets totaling $10 million and the Index is priced at 5,000. In this instance, the number of contracts would be 20. We calculate this by dividing the Fund’s value by the value of one contract. Here, $10,000,000 divided by $500,000 (obtained by multiplying the index price of 5,000 by the standard multiplier of 100) gives us 20.
However, the Fund’s notional exposure will drift during each trading day. The Fund will reallocate its portfolio either during the day’s trading session (intraday) or at the end of each trading day. That is, the Fund will allow each day’s options to expire and then settle them in cash before entering into new put options. At times, the Fund may close out existing options positions and enter into new ones intraday. By settling expiring options in cash either intraday or at the end of the day, the Fund can seek to reduce execution costs and minimize trading drift.
Fund Portfolio
The Fund’s principal holdings are described below:
The market value of the cash and treasuries held by the Fund is expected to comprise at least 80% of the Fund’s net assets.
The Fund is classified as “non-diversified” under the Investment Company Act of 1940, as amended (the “1940 Act”).
Under normal circumstances, the Fund will invest at least 80% of the value of its net assets, plus borrowings for investment purposes, in financial instruments and economic interests that provide exposure to the value of the Index. For purposes of compliance with this investment policy, derivative contracts will be valued at their notional value.
There is no guarantee that the Fund’s investment strategy will be properly implemented, and an investor may lose some or all of its investment.
None of the Fund, the Trust, the Adviser, the Sub-Adviser, or their respective affiliates makes any representation to you as to the performance of the Index.
THE FUND, TRUST, ADVISER, AND SUB-ADVISER ARE NOT AFFILIATED WITH, NOR ENDORSED BY, THE INDEX.
Index Overview: The S&P 500 Index is a widely recognized benchmark index that tracks the performance of 500 of the largest U.S.-based companies listed on the New York Stock Exchange or Nasdaq. These companies represent approximately 80% of the total U.S. equities market by capitalization, making it a large-cap index.
The S&P 500 is diversified across all sectors of the economy, including technology, healthcare, consumer discretionary, financials, industrials, and others. This distribution can vary over time as the market value of the sectors change.
Regarding volatility, the S&P 500, like all market indices, has experienced periods of significant daily price movements. Historically notable periods of volatility include the Black Monday crash in 1987, the dot-com bubble burst around 2000, the financial crisis of 2008, and the market reactions to the COVID-19 pandemic in early 2020. However, the specific degree of volatility can vary and is subject to change based on overall market conditions. Despite these periods of volatility, the Index has shown long-term growth over its history. |

| Risk [Text Block] | rr_RiskTextBlock | Referenced Index Risk. The Fund invests in options contracts that are based on the value of the Index (or in ETFs that track the Index’s performance). This subjects the Fund to certain of the same risks as if it owned shares of companies that comprised the Index or an ETF that tracks the Index, even though it does not. By virtue of the Fund’s investments in options contracts that are based on the value of the Index, the Fund may also be subject to the following risks:

| Prospectus [Line Items] | rr_ProspectusLineItems | ||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||
| Risk [Text Block] | rr_RiskTextBlock | Derivatives Risk. Derivatives are financial instruments that derive value from the underlying reference asset or assets, such as stocks, bonds, or funds (including ETFs), interest rates or indexes. The Fund’s investments in derivatives may pose risks in addition to, and greater than, those associated with directly investing in securities or other ordinary investments, including risk related to the market, imperfect correlation with underlying investments, higher price volatility, lack of availability, counterparty risk, liquidity, valuation and legal restrictions. The use of derivatives is a highly specialized activity that involves investment techniques and risks different from those associated with ordinary portfolio securities transactions. The use of derivatives may result in larger losses or smaller gains than directly investing in securities. When the Fund uses derivatives, there may be an imperfect correlation between the value of the Index and the derivative, which may prevent the Fund from achieving its investment objective. Because derivatives often require only a limited initial investment, the use of derivatives may expose the Fund to losses in excess of those amounts initially invested. In addition, the Fund’s investments in derivatives are subject to the following risks:

| Prospectus [Line Items] | rr_ProspectusLineItems | ||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||
| Risk [Text Block] | rr_RiskTextBlock | Options Contracts. The use of options contracts involves investment strategies and risks different from those associated with ordinary portfolio securities transactions. The prices of options are volatile and are influenced by, among other things, actual and anticipated changes in the value of the underlying instrument, including the anticipated volatility, which are affected by fiscal and monetary policies and by national and international political, changes in the actual or implied volatility or the reference asset, the time remaining until the expiration of the option contract and economic events. For the Fund in particular, the value of the options contracts in which it invests are substantially influenced by the value of the Index. The Fund may experience substantial downside from specific option positions and certain option positions held by the Fund may expire worthless. The options held by the Fund are exercisable at the strike price on their expiration date. As an option approaches its expiration date, its value typically increasingly moves with the value of the underlying instrument. However, prior to such date, the value of an option generally does not increase or decrease at the same rate at the underlying instrument. There may at times be an imperfect correlation between the movement in values options contracts and the underlying instrument, and there may at times not be a liquid secondary market for certain options contracts. The value of the options held by the Fund will be determined based on market quotations or other recognized pricing methods.

| Defiance S&P 500 Enhanced Options & 0DTE Income ETF | Counterparty Risk [Member] | |||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||
| Prospectus [Line Items] | rr_ProspectusLineItems | ||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||
| Risk [Text Block] | rr_RiskTextBlock | Counterparty Risk. The Fund is subject to counterparty risk by virtue of its investments in options contracts. Transactions in some types of derivatives, including options, are required to be centrally cleared (“cleared derivatives”). In a transaction involving cleared derivatives, the Fund’s counterparty is a clearing house rather than a bank or broker. Since the Fund is not a member of clearing houses and only members of a clearing house (“clearing members”) can participate directly in the clearing house, the Fund will hold cleared derivatives through accounts at clearing members. In cleared derivatives positions, the Fund will make payments (including margin payments) to and receive payments from a clearing house through their accounts at clearing members. Customer funds held at a clearing organization in connection with any options 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 options 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 clearing house, there is a risk that the assets of the Fund might not be fully protected in the event of the clearing member’s bankruptcy, as the Fund would be limited to recovering only a pro rata share of all available funds segregated on behalf of the clearing member’s customers for the relevant account class. 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. 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.

| Defiance S&P 500 Enhanced Options & 0DTE Income ETF | Price Participation Risk [Member] | |||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||
| Prospectus [Line Items] | rr_ProspectusLineItems | ||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||
| Risk [Text Block] | rr_RiskTextBlock | Price Participation Risk. The Fund employs an investment strategy that includes the sale of in-the-money put option contracts, which limits the degree to which the Fund will participate in increases in value experienced by the Index over the Call Period (typically, one day, but may range up to one week). This means that if the Index experiences an increase in value above the strike price of the sold put options during a Call Period, the Fund will likely not experience that increase to the same extent and may significantly underperform the Index over the Call Period. Additionally, because the Fund is limited in the degree to which it will participate in increases in value experienced by the Index over each Call Period, but has full exposure to any decreases in value experienced by the Index over the Call Period, the NAV of the Fund may decrease over any given time period. The Fund’s NAV is dependent on the value of each options portfolio, which is based principally upon the performance of the Index. The degree of participation in the Index gains the Fund will experience will depend on prevailing market conditions, especially market volatility, at the time the Fund enters into the sold put option contracts and will vary from Call Period to Call Period. The value of the options contracts is affected by changes in the value and dividend rates of the Index, changes in interest rates, changes in the actual or perceived volatility of the Index and the remaining time to the options’ expiration, as well as trading conditions in the options market. As the price of the Index changes and time moves towards the expiration of each Call Period, the value of the options contracts, and therefore the Fund’s NAV, will change. However, it is not expected for the Fund’s NAV to directly correlate on a day-to-day basis with the returns of the Index. The amount of time remaining until the options contract’s expiration date affects the impact of the potential options contract income on the Fund’s NAV, which may not be in full effect until the expiration date of the Fund’s options contracts. Therefore, while changes in the price of the Index will result in changes to the Fund’s NAV, the Fund generally anticipates that the rate of change in the Fund’s NAV will be different than that experienced by the Index.

| Risk [Text Block] | rr_RiskTextBlock | Distribution Risk. As part of the Fund’s investment objective to provide current income, the Fund seeks to provide monthly income distributions. There is no assurance that the Fund will make a distribution in any given month. If the Fund does make distributions, the amounts of such distributions will likely vary greatly from one distribution to the next. Additionally, the monthly distributions, if any, may consist of returns of capital, which would decrease the Fund’s NAV and trading price over time. As a result, an investor may suffer significant losses to their investment.

| Prospectus [Line Items] | rr_ProspectusLineItems | ||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||
| Risk [Text Block] | rr_RiskTextBlock | NAV Erosion Risk Due to Distributions. When the Fund makes a distribution, the Fund’s NAV will typically drop by the amount of the distribution on the related ex-dividend date (i.e., the date by which you need to own a dividend-paying stock in order to receive the upcoming dividend payment). The repeated payment of distributions by the Fund, if any, may significantly erode the Fund’s NAV and trading price over time. As a result, an investor may suffer significant losses to their investment.

| Prospectus [Line Items] | rr_ProspectusLineItems | ||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||
| Risk [Text Block] | rr_RiskTextBlock | Put Writing Strategy Risk. The path dependency (i.e., the continued use) of the Fund’s put writing strategy will impact the extent that the Fund participates in the positive price returns of the Index and, in turn, the Fund’s returns, both during the term of the sold put options and over longer time periods. If, for example, on a particular day, the Fund were to sell 1% in-the-money put options having a one-day term, the Fund’s participation in the positive price returns of the Index will be capped at 1% for that day. However, over a longer period (e.g., a five-day period), the Fund should not be expected to participate fully in the first 5% (i.e., 5 days x 1%) of the positive price returns of the Index, or the Fund may even lose money, even if the Index share price has appreciated by at least that much over such period, if during any particular day or days over that period the Index had a return less than 1%. This example illustrates that both the Fund’s participation in the positive price returns of the Index and its returns will depend not only on the price of the Index but also on the path that the Index takes over time.

| Risk [Text Block] | rr_RiskTextBlock | Authorized Participants, Market Makers, and Liquidity Providers Concentration Risk. The Fund has a limited number of financial institutions that are authorized to purchase and redeem Shares directly from the Fund (known as “Authorized Participants” or “APs”). In addition, there may be a limited number of market makers and/or liquidity providers in the marketplace. To the extent either of the following events occur, Shares may trade at a material discount to NAV and possibly face delisting: (i) APs exit the business or otherwise become unable to process creation and/or redemption orders and no other APs step forward to perform these services; or (ii) market makers and/or liquidity providers exit the business or significantly reduce their business activities and no other entities step forward to perform their functions.

| Prospectus [Line Items] | rr_ProspectusLineItems | ||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||
| Risk [Text Block] | rr_RiskTextBlock | Cash Redemption Risk. The Fund’s investment strategy may require it to redeem Shares for cash or to otherwise include cash as part of its redemption proceeds. For example, the Fund may not be able to redeem in-kind certain securities held by the Fund (e.g., derivative instruments). In such a case, the Fund may be required to sell or unwind portfolio investments to obtain the cash needed to distribute redemption proceeds. This may cause the Fund to recognize a capital gain that it might not have recognized if it had made a redemption in-kind. As a result, the Fund may pay out higher annual capital gain distributions than if the in-kind redemption process was used. By paying out higher annual capital gain distributions, investors may be subjected to increased capital gains taxes. Additionally, there may be brokerage costs or taxable gains or losses that may be imposed on the Fund in connection with a cash redemption that may not have occurred if the Fund had made a redemption in-kind. These costs could decrease the value of the Fund to the extent they are not offset by a transaction fee payable by an AP.

| Risk [Text Block] | rr_RiskTextBlock | Trading. Although Shares are listed on a national securities exchange, such as NYSE Arca, Inc. (the “Exchange”), and may be traded on U.S. exchanges other than the Exchange, there can be no assurance that an active trading market for the Shares will develop or be maintained or that the Shares will trade with any volume, or at all, on any stock exchange. This risk may be greater for the Fund as it seeks to have exposure to a single underlying stock as opposed to a more diverse portfolio like a traditional pooled investment. In stressed market conditions, the liquidity of Shares may begin to mirror the liquidity of the Fund’s underlying portfolio holdings, which can be significantly less liquid than Shares. Shares trade on the Exchange at a market price that may be below, at or above the Fund’s NAV. Trading in Shares on the Exchange may be halted due to market conditions or for reasons that, in the view of the Exchange, make trading in Shares inadvisable. In addition, trading in Shares on the Exchange is subject to trading halts caused by extraordinary market volatility pursuant to the Exchange “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. In the event of an unscheduled market close for options contracts that reference a single stock, such as the Index’s securities being halted or a market wide closure, settlement prices will be determined by the procedures of the listing exchange of the options contracts. As a result, the Fund could be adversely affected and be unable to implement its investment strategies in the event of an unscheduled closing.

| Risk [Text Block] | rr_RiskTextBlock | High Portfolio Turnover Risk. The Fund may actively and frequently trade all or a significant portion of the Fund’s holdings.

| Prospectus [Line Items] | rr_ProspectusLineItems | ||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||
| Risk [Text Block] | rr_RiskTextBlock | Liquidity Risk. Some securities held by the Fund, including options contracts, may be difficult to sell or be illiquid, particularly during times of market turmoil. This risk is greater for the Fund as it will hold options contracts on a single security, and not a broader range of options contracts. Markets for securities or financial instruments could be disrupted by a number of events, including, but not limited to, an economic crisis, natural disasters, epidemics/pandemics, new legislation or regulatory changes inside or outside the United States. Illiquid securities may be difficult to value, especially in changing or volatile markets. If the Fund is forced to sell an illiquid security at an unfavorable time or price, the Fund may be adversely impacted. Certain market conditions or restrictions, such as market rules related to short sales, may prevent the Fund from limiting losses, realizing gains or achieving a high correlation with the Index. There is no assurance that a security that is deemed liquid when purchased will continue to be liquid. Market illiquidity may cause losses for the Fund.

The Fund may use a variety of money market instruments for cash management purposes, including money market funds, depositary accounts and repurchase agreements. Repurchase agreements are contracts in which a seller of securities agrees to buy the securities back at a specified time and price. Repurchase agreements may be subject to market and credit risk related to the collateral securing the repurchase agreement. Money market instruments, including money market funds, may lose money through fees or other means.

Because the Fund is “non-diversified,” it may invest a greater percentage of its assets in the securities of a single issuer or a smaller number of issuers than if it was a diversified fund. As a result, a decline in the value of an investment in a single issuer or a smaller number of issuers could cause the Fund’s overall value to decline to a greater degree than if the Fund held a more diversified portfolio.

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, Adviser, and Sub-Adviser seek to reduce these operational risks through controls and procedures, there is no way to completely protect against such risks.

| Risk [Text Block] | rr_RiskTextBlock | U.S. Government and U.S. Agency Obligations Risk. The Fund may invest in securities issued by the U.S. government or its agencies or instrumentalities. U.S. Government obligations include securities issued or guaranteed as to principal and interest by the U.S. Government, its agencies or instrumentalities, such as the U.S. Treasury. Payment of principal and interest on U.S. Government obligations may be backed by the full faith and credit of the United States or may be backed solely by the issuing or guaranteeing agency or instrumentality itself. In the latter case, the investor must look principally to the agency or instrumentality issuing or guaranteeing the obligation for ultimate repayment, which agency or instrumentality may be privately owned. There can be no assurance that the U.S. Government would provide financial support to its agencies or instrumentalities (including government-sponsored enterprises) where it is not obligated to do so.

| Strategy [Heading] | rr_StrategyHeading | Principal Investment Strategies | |||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||
| Strategy Narrative [Text Block] | rr_StrategyNarrativeTextBlock | The Fund is an actively managed exchange-traded fund (“ETF”) that seeks current income while maintaining the opportunity for indirect exposure to the value of the Index, subject to a limit on potential gains from increases in the value of the Index. More precisely, the Fund aims to generate additional income from its options investments when the Index rises in value, based on the specific put options it sold.
The Fund will seek to employ its investment strategy as it relates to the Index 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. As further described below, each day, the Fund uses an at-the-money and in-the-money put selling strategy to provide income and exposure to the value of the Index, subject to a limit on potential investment gains as a result of the nature of the options strategy it employs. The Fund’s options contracts provide current income from option premiums and a limit on the Fund’s indirect participation in gains, if any, of the increase in the value of the Index. In addition, the Fund’s in-the-money put options will provide some upside appreciation, also known as “intrinsic value.” As discussed in greater detail below, the Fund will not directly or fully participate in gains experienced by the Index. Please see “Additional Information about the Fund” below for a description of options terminology.
Every day, the Fund will sell put options that are priced either at-the-money or up to five percent in-the-money (i.e., higher than the current market price). If the Fund sells an option that’s priced above the current market price, the Fund may profit if the Index increases in value above its current price. This opportunity exists until the option’s expiration date, which is typically the next day (1DTE) or the same day (0DTE). This happens because an option priced above the current market value has a higher premium than an option priced at the current market value. In other words, the Fund’s potential for profit (or exposure) fluctuates. This potential for profit is calculated daily over a certain time period, but it’s also balanced out by any losses that might occur during that same period.
The Fund seeks to make monthly distributions. To enable it to do so, the Fund seeks to generate a consistent stream of income on a daily basis. In particular, the Fund sells in-the-money put options to seek a minimum daily income of 0.15%. If the Sub-Adviser determines this 0.15% daily income is not achievable, the Fund will sell options that are priced at the current market value to try to make the most of the available daily income. If the potential daily income exceeds 0.15%, then the Sub-Adviser will select a target strike to seek an equal mix of current and potential income.
In addition to its options investments, the Fund will hold short-term U.S. Treasury securities for collateral for the options, and to generate income.
The Fund’s options contracts provide:
For more information, see the section “The Fund’s Use of Index Option Contracts” below.
The Fund’s investment adviser is Tidal Investments LLC ( the “Adviser”) and the investment sub-adviser is ZEGA Financial, LLC (“ZEGA” or the “Sub-Adviser”).
Why invest in the Fund?
That is, although the Fund will not fully participate in gains in the value of the Index, the Fund’s portfolio is designed to generate income.
An Investment in the Fund is not an investment in the Index, nor is the Fund an investment in a traditional passively managed index fund.
Additional information regarding the Index is also set forth below.
The Fund’s Use of Index Option Contracts
Each day, the Fund will sell at-the-money and in-the-money puts on the Index (or on passively managed ETFs that seek to track the Index’s performance). In particular, the Fund will sell puts with near-term expirations at a range of 0% to 5% “in-the-money” (i.e., that is where the strike price is above the current value of the Index by between 0% and 5%). The Fund will receive premium income for each put sold. In addition, the strategy will provide the Fund with the opportunity to earn both time decay (described below) and, for in-the-money puts, a limited amount of upside appreciation up to the puts’ strike price (described below) plus the puts’ intrinsic value. The expiration dates at the time of purchase for the Fund’s sold puts will range from same day expiration to a week. The Fund’s participation in potential increases in the value of the Index is based on the level of the Index at the time the Fund sells a put option contract and the Index’s level at the time of the contract’s expiration.
For example, for simplicity, assume the Index is trading at 100 at the time the Fund sells an in-the-money put with a strike price of 105. If the Index’s level increases to 105 before expiration, the Fund would benefit from the increase in the Index’s value up to 105 through the receipt of the premium which was earned through the sale of the option. In addition, the Fund would benefit slightly from the in-the-money put’s extrinsic value. That is, if the Fund sold the put for 0.50% of time value (an amount paid above the put’s in-the-money value for the put’s potential to increase in value before expiration), the option in the example would earn up to 105.5. However, if the Index’s increase exceeded 105, the Fund would not participate in any of the additional upside.
Further, if the Index level drops below 100 at expiration minus an amount equal to the puts’ time value, the Fund would lose money. So, if the Fund sold the option for 0.50 of time value, the Fund would lose money if the Index fell below 99.5. The Fund would be obligated to cash settle the put option the difference between the strike price and the actual level of the Index, multiplied by the contract multiplier (usually 100 for equity index options).
The Fund seeks to make monthly distributions. To enable it to do so, the Fund seeks to generate a consistent stream of income on a daily basis. In particular, the Fund sells in-the-money put options to seek a minimum daily income of 0.15%. If the Sub-Adviser determines this 0.15% daily income is not achievable, the Fund will sell options that are priced at the current market value to try to make the most of the available daily income. If the potential daily income exceeds 0.15%, then the Sub-Adviser will select a target strike to seek an equal mix of current and potential income. Through this approach, the Fund seeks to provide an “enhanced” yield compared to traditional option-based strategies. It does this by frequently selling short-term options (typically less than one week in duration), which usually generates more income than selling longer-term options over the same period.
The Fund intends to invest only in cash-settled options, which means the holder of the option doesn’t receive securities when the option is exercised or expires. Instead, any payments are made in cash.
U.S. Treasuries
The Fund will hold short-term U.S. Treasury securities as collateral in connection with the Fund’s options strategy and to generate income.
Fund’s Monthly Distributions
The Fund will seek to provide monthly income in the form of cash distributions. The Fund will seek to generate such income in the following two ways:
Fund’s Return Profile vs the Index
For the reasons stated above, the Fund’s performance will differ from that of the Index’s value. The performance differences will depend on, among other things, the value of the Index, changes in the value of Index put options contracts the Fund has sold, and changes in the value of the U.S. Treasuries.
The Fund’s strategy is designed to have approximately a daily, unleveraged, 100% notional exposure to the Index. Essentially, the worth of the put options that the Fund invests in will match the value as if the Fund had directly purchased the securities included in the Index.
Let’s consider a scenario where the Fund has assets totaling $10 million and the Index is priced at 5,000. In this instance, the number of contracts would be 20. We calculate this by dividing the Fund’s value by the value of one contract. Here, $10,000,000 divided by $500,000 (obtained by multiplying the index price of 5,000 by the standard multiplier of 100) gives us 20.
However, the Fund’s notional exposure will drift during each trading day. The Fund will reallocate its portfolio either during the day’s trading session (intraday) or at the end of each trading day. That is, the Fund will allow each day’s options to expire and then settle them in cash before entering into new put options. At times, the Fund may close out existing options positions and enter into new ones intraday. By settling expiring options in cash either intraday or at the end of the day, the Fund can seek to reduce execution costs and minimize trading drift.
Fund Portfolio
The Fund’s principal holdings are described below:
The market value of the cash and treasuries held by the Fund is expected to comprise at least 80% of the Fund’s net assets.
The Fund is classified as “non-diversified” under the Investment Company Act of 1940, as amended (the “1940 Act”).
Under normal circumstances, the Fund will invest at least 80% of the value of its net assets, plus borrowings for investment purposes, in financial instruments and economic interests that provide exposure to the value of the Index. For purposes of compliance with this investment policy, derivative contracts will be valued at their notional value.
There is no guarantee that the Fund’s investment strategy will be properly implemented, and an investor may lose some or all of its investment.
None of the Fund, the Trust, the Adviser, the Sub-Adviser, or their respective affiliates makes any representation to you as to the performance of the Index.
THE FUND, TRUST, ADVISER, AND SUB-ADVISER ARE NOT AFFILIATED WITH, NOR ENDORSED BY, THE INDEX.
Index Overview: The Russell 2000 Index is a widely recognized benchmark index that tracks the performance of approximately 2000 small-cap companies in the United States. These are the smallest companies listed in the Russell 3000 Index, representing about 10% of that index’s total market capitalization.
The Russell 2000 Index is diversified and includes companies from various sectors such as financial services, healthcare, technology, consumer discretionary, industrials, and others. The exact distribution can fluctuate over time due to market conditions.
In terms of volatility, the Index, being a small-cap index, tends to be more volatile than large-cap indices like the S&P 500 or the Nasdaq 100 indices. Small-cap stocks can be more sensitive to changes in the economic climate and can experience larger price swings. Notable periods of volatility have included the dot-com bubble burst in 2000, the financial crisis in 2008, and the market turmoil caused by the COVID-19 pandemic in 2020. However, as with any index, the specific level of volatility can change based on broader market conditions.

| Risk [Text Block] | rr_RiskTextBlock | Derivatives Risk. Derivatives are financial instruments that derive value from the underlying reference asset or assets, such as stocks, bonds, or funds (including ETFs), interest rates or indexes. The Fund’s investments in derivatives may pose risks in addition to, and greater than, those associated with directly investing in securities or other ordinary investments, including risk related to the market, imperfect correlation with underlying investments, higher price volatility, lack of availability, counterparty risk, liquidity, valuation and legal restrictions. The use of derivatives is a highly specialized activity that involves investment techniques and risks different from those associated with ordinary portfolio securities transactions. The use of derivatives may result in larger losses or smaller gains than directly investing in securities. When the Fund uses derivatives, there may be an imperfect correlation between the value of the Index and the derivative, which may prevent the Fund from achieving its investment objective. Because derivatives often require only a limited initial investment, the use of derivatives may expose the Fund to losses in excess of those amounts initially invested. In addition, the Fund’s investments in derivatives are subject to the following risks:

| Risk [Text Block] | rr_RiskTextBlock | Options Contracts. The use of options contracts involves investment strategies and risks different from those associated with ordinary portfolio securities transactions. The prices of options are volatile and are influenced by, among other things, actual and anticipated changes in the value of the underlying instrument, including the anticipated volatility, which are affected by fiscal and monetary policies and by national and international political, changes in the actual or implied volatility or the reference asset, the time remaining until the expiration of the option contract and economic events. For the Fund in particular, the value of the options contracts in which it invests are substantially influenced by the value of the Index. The Fund may experience substantial downside from specific option positions and certain option positions held by the Fund may expire worthless. The options held by the Fund are exercisable at the strike price on their expiration date. As an option approaches its expiration date, its value typically increasingly moves with the value of the underlying instrument. However, prior to such date, the value of an option generally does not increase or decrease at the same rate at the underlying instrument. There may at times be an imperfect correlation between the movement in values options contracts and the underlying instrument, and there may at times not be a liquid secondary market for certain options contracts. The value of the options held by the Fund will be determined based on market quotations or other recognized pricing methods.

| Prospectus [Line Items] | rr_ProspectusLineItems | ||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||
| Risk [Text Block] | rr_RiskTextBlock | Counterparty Risk. The Fund is subject to counterparty risk by virtue of its investments in options contracts. Transactions in some types of derivatives, including options, are required to be centrally cleared (“cleared derivatives”). In a transaction involving cleared derivatives, the Fund’s counterparty is a clearing house rather than a bank or broker. Since the Fund is not a member of clearing houses and only members of a clearing house (“clearing members”) can participate directly in the clearing house, the Fund will hold cleared derivatives through accounts at clearing members. In cleared derivatives positions, the Fund will make payments (including margin payments) to and receive payments from a clearing house through their accounts at clearing members. Customer funds held at a clearing organization in connection with any options 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 options 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 clearing house, there is a risk that the assets of the Fund might not be fully protected in the event of the clearing member’s bankruptcy, as the Fund would be limited to recovering only a pro rata share of all available funds segregated on behalf of the clearing member’s customers for the relevant account class. 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. 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.

| Prospectus [Line Items] | rr_ProspectusLineItems | ||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||
| Risk [Text Block] | rr_RiskTextBlock | Price Participation Risk. The Fund employs an investment strategy that includes the sale of in-the-money put option contracts, which limits the degree to which the Fund will participate in increases in value experienced by the Index over the Call Period (typically, one day, but may range up to one week). This means that if the Index experiences an increase in value above the strike price of the sold put options during a Call Period, the Fund will likely not experience that increase to the same extent and may significantly underperform the Index over the Call Period. Additionally, because the Fund is limited in the degree to which it will participate in increases in value experienced by the Index over each Call Period, but has full exposure to any decreases in value experienced by the Index over the Call Period, the NAV of the Fund may decrease over any given time period. The Fund’s NAV is dependent on the value of each options portfolio, which is based principally upon the performance of the Index. The degree of participation in the Index gains the Fund will experience will depend on prevailing market conditions, especially market volatility, at the time the Fund enters into the sold put option contracts and will vary from Call Period to Call Period. The value of the options contracts is affected by changes in the value and dividend rates of the Index, changes in interest rates, changes in the actual or perceived volatility of the Index and the remaining time to the options’ expiration, as well as trading conditions in the options market. As the price of the Index changes and time moves towards the expiration of each Call Period, the value of the options contracts, and therefore the Fund’s NAV, will change. However, it is not expected for the Fund’s NAV to directly correlate on a day-to-day basis with the returns of the Index. The amount of time remaining until the options contract’s expiration date affects the impact of the potential options contract income on the Fund’s NAV, which may not be in full effect until the expiration date of the Fund’s options contracts. Therefore, while changes in the price of the Index will result in changes to the Fund’s NAV, the Fund generally anticipates that the rate of change in the Fund’s NAV will be different than that experienced by the Index.

There is no assurance that the Fund will make a distribution in any given month. If the Fund does make distributions, the amounts of such distributions will likely vary greatly from one distribution to the next. Additionally, the monthly distributions, if any, may consist of returns of capital, which would decrease the Fund’s NAV and trading price over time.

| Risk [Text Block] | rr_RiskTextBlock | Put Writing Strategy Risk. The path dependency (i.e., the continued use) of the Fund’s put writing strategy will impact the extent that the Fund participates in the positive price returns of the Index and, in turn, the Fund’s returns, both during the term of the sold put options and over longer time periods. If, for example, on a particular day, the Fund were to sell 1% in-the-money put options having a one-day term, the Fund’s participation in the positive price returns of the Index will be capped at 1% for that day. However, over a longer period (e.g., a five-day period), the Fund should not be expected to participate fully in the first 5% (i.e., 5 days x 1%) of the positive price returns of the Index, or the Fund may even lose money, even if the Index share price has appreciated by at least that much over such period, if during any particular day or days over that period the Index had a return less than 1%. This example illustrates that both the Fund’s participation in the positive price returns of the Index and its returns will depend not only on the price of the Index but also on the path that the Index takes over time.

| Risk [Text Block] | rr_RiskTextBlock | Cash Redemption Risk. The Fund’s investment strategy may require it to redeem Shares for cash or to otherwise include cash as part of its redemption proceeds. For example, the Fund may not be able to redeem in-kind certain securities held by the Fund (e.g., derivative instruments). In such a case, the Fund may be required to sell or unwind portfolio investments to obtain the cash needed to distribute redemption proceeds. This may cause the Fund to recognize a capital gain that it might not have recognized if it had made a redemption in-kind. As a result, the Fund may pay out higher annual capital gain distributions than if the in-kind redemption process was used. By paying out higher annual capital gain distributions, investors may be subjected to increased capital gains taxes. Additionally, there may be brokerage costs or taxable gains or losses that may be imposed on the Fund in connection with a cash redemption that may not have occurred if the Fund had made a redemption in-kind. These costs could decrease the value of the Fund to the extent they are not offset by a transaction fee payable by an AP.

| Risk [Text Block] | rr_RiskTextBlock | Trading. Although Shares are listed on a national securities exchange, such as NYSE Arca, Inc. (the “Exchange”), and may be traded on U.S. exchanges other than the Exchange, there can be no assurance that an active trading market for the Shares will develop or be maintained or that the Shares will trade with any volume, or at all, on any stock exchange. This risk may be greater for the Fund as it seeks to have exposure to a single underlying stock as opposed to a more diverse portfolio like a traditional pooled investment. In stressed market conditions, the liquidity of Shares may begin to mirror the liquidity of the Fund’s underlying portfolio holdings, which can be significantly less liquid than Shares. Shares trade on the Exchange at a market price that may be below, at or above the Fund’s NAV. Trading in Shares on the Exchange may be halted due to market conditions or for reasons that, in the view of the Exchange, make trading in Shares inadvisable. In addition, trading in Shares on the Exchange is subject to trading halts caused by extraordinary market volatility pursuant to the Exchange “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. In the event of an unscheduled market close for options contracts that reference a single stock, such as the Index’s securities being halted or a market wide closure, settlement prices will be determined by the procedures of the listing exchange of the options contracts. As a result, the Fund could be adversely affected and be unable to implement its investment strategies in the event of an unscheduled closing.

| Risk [Text Block] | rr_RiskTextBlock | Liquidity Risk. Some securities held by the Fund, including options contracts, may be difficult to sell or be illiquid, particularly during times of market turmoil. This risk is greater for the Fund as it will hold options contracts on a single security, and not a broader range of options contracts. Markets for securities or financial instruments could be disrupted by a number of events, including, but not limited to, an economic crisis, natural disasters, epidemics/pandemics, new legislation or regulatory changes inside or outside the United States. Illiquid securities may be difficult to value, especially in changing or volatile markets. If the Fund is forced to sell an illiquid security at an unfavorable time or price, the Fund may be adversely impacted. Certain market conditions or restrictions, such as market rules related to short sales, may prevent the Fund from limiting losses, realizing gains or achieving a high correlation with the Index. There is no assurance that a security that is deemed liquid when purchased will continue to be liquid. Market illiquidity may cause losses for the Fund.

| Risk [Text Block] | rr_RiskTextBlock | Market Events Risk. The Fund’s investments are subject to changes in general economic conditions, general market fluctuations and the risks inherent in investment in securities and other financial instruments. Investment markets can be volatile and prices of investments can change substantially due to various factors including, but not limited to, economic growth or recession, changes in interest rates, inflation, changes in the actual or perceived creditworthiness of issuers, and general market liquidity. The Fund is subject to the risk that geopolitical events will disrupt securities and other financial markets and adversely affect global economies and markets. Local, regional or global events such as war, military conflicts, acts of terrorism, natural disasters, the spread of infectious illness or other public health issues, or other events could have a significant impact on the Fund and its investments. Continuing uncertainties regarding interest rates, rising inflation, political events, rising government debt in the U.S. and trade tensions also contribute to market volatility. Conflict, loss of life and disaster connected to ongoing armed conflict between Ukraine and Russia in Europe and between Israel and Hamas in the Middle East could have severe adverse effects on the related region, including significant adverse effects on the regional or global economies and the markets for certain securities. The U.S. and the European Union have imposed sanctions on certain Russian individuals and companies, including certain financial institutions, and have limited certain exports and imports to and from Russia. These conflicts have contributed to recent market volatility and may continue to do so.

| Risk [Text Block] | rr_RiskTextBlock | Russell 2000 Index Risks: The Index, which consists of small-cap U.S. companies, is particularly susceptible to economic changes, as these firms often have less financial resilience than larger companies.

| Strategy [Heading] | rr_StrategyHeading | Principal Investment Strategies | |||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||
| Strategy Narrative [Text Block] | rr_StrategyNarrativeTextBlock | The Fund is an actively managed exchange-traded fund (“ETF”) that primarily seeks to generate current income. The Fund’s strategy involves holding shares of unaffiliated passively managed ETFs that seek to track the performance of the Index (“Index ETFs”) and selling daily credit call spreads on the Index. The Fund’s daily credit call spread strategy consists of selling a call option and simultaneously buying another call option at a higher strike price for income generation.
The Fund’s investment approach is designed to generate income through option premiums derived from selling Index call spreads, which will be the primary driver of the Fund’s yield. To retain upside growth potential (if the value of the Index increases) and seek a target annual income level of 20% (the “Annual Target”), the Fund sells at-the-money or near-the-money call spreads. The sold call spreads generate premium and also allow the Fund to benefit if the Index’s value increases above the call spreads cap (described below) via its Index ETF holdings. Additionally, the Fund will maintain a minor allocation to cash or U.S. Treasuries, not exceeding ten percent of its total assets.
The Fund will employ its investment strategy regardless of fluctuating market, economic, or other conditions, and will not seek to take temporary defensive positions during such periods. Each day, the Fund will sell Index call spreads to generate net income from the options premiums. These spreads will be designed to seek the Annual Target level of income while maintaining exposure to the value of the Index.
Each day, the Fund will sell credit call spreads on the Index, focusing on options with near-term expiration. This involves selling call options at a strike price at or near the money and buying call options above that strike price. If the Index’s value rises above the upper strike price (the call spreads cap), the Fund will profit from further upside appreciation in the value of the Index.
The Fund aims for consistent monthly distributions, primarily relying on the income generated from selling the call spreads. If the anticipated daily income from these activities surpasses a set threshold, ZEGA Financial, LLC (Sub-Adviser), may adjust the strategy to seek to meet a daily income target that will enable the Fund to, in turn, achieve the Annual Target, although there is no guarantee that the Fund will be able to achieve its Annual Target.
This strategy seeks to offer an “enhanced” yield compared to traditional option-based strategies by focusing on short-term options, which typically yield higher income than equivalent longer-term options.
In addition to options trading, the Fund will hold cash or short-term U.S. Treasury securities. These securities serve a dual purpose: providing collateral for the options strategy and contributing to the Fund’s income generation.
Dividends paid by the Fund’s Index ETF holdings will contribute to the Fund’s income generation.
The Fund’s options contracts will:
For more information, see the section “The Fund’s Use of Index Option Contracts” below.
Why invest in the Fund?
● The Fund seeks to generate monthly income at the Annual Target, which is not dependent on the value of the Index.
● The Fund seeks to participate in some of the potential gains experienced by increases in the value of the Index.
That is, although the Fund will not fully participate in gains in the value of the Index, the Fund’s portfolio is designed to generate income and benefit if the Index’s value increases above the call spreads cap (via its Index ETF holdings).
An investment in the Fund is not an investment in the Index, nor is the Fund an investment in a traditional passively managed index fund.
The Fund’s strategy is subject to all potential losses if the Index loses value, which may not be offset by income received by the Fund.
Additional information regarding the Index is also set forth below.
The Fund’s Use of Index Option Contracts
The Fund’s approach to Index option contracts entails selling daily Index credit call spreads. The Fund will earn net premium income, with an opportunity to gain from the time decay of options.
Fund Portfolio
The Fund’s portfolio is comprised mainly of:
The Fund intends to invest in cash-settled options, which means the holder of the option doesn’t receive securities when the option is exercised or expires. Instead, any payments are made in cash.
The Fund is classified as “non-diversified” under the 1940 Act.
Under normal circumstances, the Fund will invest at least 80% of the value of its net assets, plus borrowings for investment purposes, in financial instruments and economic interests that provide exposure to the value of the Index. For purposes of compliance with this investment policy, derivative contracts will be valued at their notional value.
THE FUND, TRUST, ADVISER, AND SUB-ADVISER ARE NOT AFFILIATED WITH, NOR ENDORSED BY, THE INDEX.
Index Overview: The Nasdaq 100 Index is a benchmark index that includes 100 of the largest non-financial companies listed on the Nasdaq Stock Market, based on market capitalization. This makes it a large-cap index, meaning its constituents have a high market value, often in the billions of dollars.
The Index includes companies from various industries but is heavily weighted towards the technology sector. This reflects the Nasdaq’s historic strength as a listing venue for tech companies. Other sectors represented include consumer discretionary, health care, communication services, and industrials, among others.
In terms of volatility, like all stock indices, the Index experiences daily price movements and can be significantly volatile at times. This is often driven by macroeconomic factors, market sentiment, and financial results or news from its large constituents. Historical periods of significant volatility include the dot-com bubble burst around 2000 and the global financial crisis of 2007-2008, among other events. However, the specific degree of volatility can vary and is subject to change based on market conditions. |

| Risk [Text Block] | rr_RiskTextBlock | The Nasdaq 100 Index Risks: The Index’s major risks stem from its high concentration in the technology sector and significant exposure to high-growth, high-valuation companies. A downturn in the tech industry, whether from regulatory changes, shifts in technology, or competitive pressures, can greatly impact the index. It’s also vulnerable to geopolitical risks due to many constituent companies having substantial international operations. Since many of these tech companies often trade at high valuations, a shift in investor sentiment could lead to significant price declines.

| Risk [Text Block] | rr_RiskTextBlock | Derivatives Risk. Derivatives are financial instruments that derive value from the underlying reference asset or assets, such as stocks, bonds, or funds (including ETFs), interest rates or indexes. The Fund’s investments in derivatives may pose risks in addition to, and greater than, those associated with directly investing in securities or other ordinary investments, including risk related to the market, imperfect correlation with underlying investments, higher price volatility, lack of availability, counterparty risk, liquidity, valuation and legal restrictions. The use of derivatives is a highly specialized activity that involves investment techniques and risks different from those associated with ordinary portfolio securities transactions. The use of derivatives may result in larger losses or smaller gains than directly investing in securities. When the Fund uses derivatives, there may be an imperfect correlation between the value of the Index and the derivative, which may prevent the Fund from achieving its investment objective. Because derivatives often require only a limited initial investment, the use of derivatives may expose the Fund to losses in excess of those amounts initially invested. In addition, the Fund’s investments in derivatives are subject to the following risks:

| Risk [Text Block] | rr_RiskTextBlock | Options Contracts. The use of options contracts involves investment strategies and risks different from those associated with ordinary portfolio securities transactions. The prices of options are volatile and are influenced by, among other things, actual and anticipated changes in the value of the underlying instrument, including the anticipated volatility, which are affected by fiscal and monetary policies and by national and international political, changes in the actual or implied volatility or the reference asset, the time remaining until the expiration of the option contract and economic events. For the Fund in particular, the value of the options contracts in which it invests are substantially influenced by the value of the Index. The Fund may experience substantial downside from specific option positions and certain option positions held by the Fund may expire worthless. The options held by the Fund are exercisable at the strike price on their expiration date. As an option approaches its expiration date, its value typically increasingly moves with the value of the underlying instrument. However, prior to such date, the value of an option generally does not increase or decrease at the same rate at the underlying instrument. There may at times be an imperfect correlation between the movement in values options contracts and the underlying instrument, and there may at times not be a liquid secondary market for certain options contracts. The value of the options held by the Fund will be determined based on market quotations or other recognized pricing methods.

| Prospectus [Line Items] | rr_ProspectusLineItems | ||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||
| Risk [Text Block] | rr_RiskTextBlock | Counterparty Risk. The Fund is subject to counterparty risk by virtue of its investments in options contracts. Transactions in some types of derivatives, including options, are required to be centrally cleared (“cleared derivatives”). In a transaction involving cleared derivatives, the Fund’s counterparty is a clearing house rather than a bank or broker. Since the Fund is not a member of clearing houses and only members of a clearing house (“clearing members”) can participate directly in the clearing house, the Fund will hold cleared derivatives through accounts at clearing members. In cleared derivatives positions, the Fund will make payments (including margin payments) to and receive payments from a clearing house through their accounts at clearing members. Customer funds held at a clearing organization in connection with any options 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 options 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 clearing house, there is a risk that the assets of the Fund might not be fully protected in the event of the clearing member’s bankruptcy, as the Fund would be limited to recovering only a pro rata share of all available funds segregated on behalf of the clearing member’s customers for the relevant account class. 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. 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.

There is no assurance that the Fund will make a distribution in any given month. If the Fund does make distributions, the amounts of such distributions will likely vary greatly from one distribution to the next. Additionally, the monthly distributions, if any, may consist of returns of capital, which would decrease the Fund’s NAV and trading price over time. As a result, an investor may suffer significant losses to their investment.

| Risk [Text Block] | rr_RiskTextBlock | Authorized Participants, Market Makers, and Liquidity Providers Concentration Risk. The Fund has a limited number of financial institutions that are authorized to purchase and redeem Shares directly from the Fund (known as “Authorized Participants” or “APs”). In addition, there may be a limited number of market makers and/or liquidity providers in the marketplace. To the extent either of the following events occur, Shares may trade at a material discount to NAV and possibly face delisting: (i) APs exit the business or otherwise become unable to process creation and/or redemption orders and no other APs step forward to perform these services; or (ii) market makers and/or liquidity providers exit the business or significantly reduce their business activities and no other entities step forward to perform their functions.

| Risk [Text Block] | rr_RiskTextBlock | Cash Redemption Risk. The Fund’s investment strategy may require it to redeem Shares for cash or to otherwise include cash as part of its redemption proceeds. For example, the Fund may not be able to redeem in-kind certain securities held by the Fund (e.g., derivative instruments). In such a case, the Fund may be required to sell or unwind portfolio investments to obtain the cash needed to distribute redemption proceeds. This may cause the Fund to recognize a capital gain that it might not have recognized if it had made a redemption in-kind. As a result, the Fund may pay out higher annual capital gain distributions than if the in-kind redemption process was used. By paying out higher annual capital gain distributions, investors may be subjected to increased capital gains taxes. Additionally, there may be brokerage costs or taxable gains or losses that may be imposed on the Fund in connection with a cash redemption that may not have occurred if the Fund had made a redemption in-kind. These costs could decrease the value of the Fund to the extent they are not offset by a transaction fee payable by an AP.

| Risk [Text Block] | rr_RiskTextBlock | Trading. Although Shares are listed on a national securities exchange, such as The Nasdaq Stock Market, LLC (the “Exchange”), and may be traded on U.S. exchanges other than the Exchange, there can be no assurance that an active trading market for the Shares will develop or be maintained or that the Shares will trade with any volume, or at all, on any stock exchange. This risk may be greater for the Fund as it seeks to have exposure to a single underlying stock as opposed to a more diverse portfolio like a traditional pooled investment. In stressed market conditions, the liquidity of Shares may begin to mirror the liquidity of the Fund’s underlying portfolio holdings, which can be significantly less liquid than Shares. Shares trade on the Exchange at a market price that may be below, at or above the Fund’s NAV. Trading in Shares on the Exchange may be halted due to market conditions or for reasons that, in the view of the Exchange, make trading in Shares inadvisable. In addition, trading in Shares on the Exchange is subject to trading halts caused by extraordinary market volatility pursuant to the Exchange “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. In the event of an unscheduled market close for options contracts that reference a single stock, such as the Index’s securities being halted or a market wide closure, settlement prices will be determined by the procedures of the listing exchange of the options contracts. As a result, the Fund could be adversely affected and be unable to implement its investment strategies in the event of an unscheduled closing.

| Risk [Text Block] | rr_RiskTextBlock | Liquidity Risk. Some securities held by the Fund, including options contracts, may be difficult to sell or be illiquid, particularly during times of market turmoil. This risk is greater for the Fund as it will hold options contracts on a single security, and not a broader range of options contracts. Markets for securities or financial instruments could be disrupted by a number of events, including, but not limited to, an economic crisis, natural disasters, epidemics/pandemics, new legislation or regulatory changes inside or outside the United States. Illiquid securities may be difficult to value, especially in changing or volatile markets. If the Fund is forced to sell an illiquid security at an unfavorable time or price, the Fund may be adversely impacted. Certain market conditions or restrictions, such as market rules related to short sales, may prevent the Fund from limiting losses, realizing gains or achieving a high correlation with the Index. There is no assurance that a security that is deemed liquid when purchased will continue to be liquid. Market illiquidity may cause losses for the Fund.

The Fund’s investments are subject to changes in general economic conditions, general market fluctuations and the risks inherent in investment in securities and other financial instruments. Investment markets can be volatile and prices of investments can change substantially due to various factors including, but not limited to, economic growth or recession, changes in interest rates, inflation, changes in the actual or perceived creditworthiness of issuers, and general market liquidity. The Fund is subject to the risk that geopolitical events will disrupt securities and other financial markets and adversely affect global economies and markets. Local, regional or global events such as war, military conflicts, acts of terrorism, natural disasters, the spread of infectious illness or other public health issues, or other events could have a significant impact on the Fund and its investments. Continuing uncertainties regarding interest rates, rising inflation, political events, rising government debt in the U.S. and trade tensions also contribute to market volatility. Conflict, loss of life and disaster connected to ongoing armed conflict between Ukraine and Russia in Europe and between Israel and Hamas in the Middle East could have severe adverse effects on the related region, including significant adverse effects on the regional or global economies and the markets for certain securities. The U.S. and the European Union have imposed sanctions on certain Russian individuals and companies, including certain financial institutions, and have limited certain exports and imports to and from Russia. These conflicts have contributed to recent market volatility and may continue to do so.

| Strategy [Heading] | rr_StrategyHeading | Principal Investment Strategies | |||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||
| Strategy Narrative [Text Block] | rr_StrategyNarrativeTextBlock | The Fund is an actively managed exchange-traded fund (“ETF”) that primarily seeks to generate current income. The Fund’s strategy involves holding shares of unaffiliated passively managed ETFs that seek to track the performance of the Index (“Index ETFs”) and selling daily credit call spreads on the Index. The Fund’s daily credit call spread strategy consists of selling a call option and simultaneously buying another call option at a higher strike price for income generation.
The Fund’s investment approach is designed to generate income through option premiums derived from selling Index call spreads, which will be the primary driver of the Fund’s yield. To retain upside growth potential (if the value of the Index increases) and seek a target annual income level of 20% (the “Annual Target”), the Fund sells at-the-money or near-the-money call spreads. The sold call spreads generate premium and also allow the Fund to benefit if the Index’s value increases above the call spreads cap (described below) via its Index ETF holdings. Additionally, the Fund will maintain a minor allocation to cash or U.S. Treasuries, not exceeding ten percent of its total assets.
The Fund will employ its investment strategy regardless of fluctuating market, economic, or other conditions, and will not seek to take temporary defensive positions during such periods. Each day, the Fund will sell Index call spreads to generate net income from the options premiums. These spreads will be designed to seek the Annual Target level of income while maintaining exposure to the value of the Index.
Each day, the Fund will sell credit call spreads on the Index, focusing on options with near-term expiration. This involves selling call options at a strike price at or near the money and buying call options above that strike price. If the Index’s value rises above the upper strike price (the call spreads cap), the Fund will profit from further upside appreciation in the value of the Index.
The Fund aims for consistent monthly distributions, primarily relying on the income generated from selling the call spreads. If the anticipated daily income from these activities surpasses a set threshold, ZEGA Financial, LLC (Sub-Adviser), may adjust the strategy to seek to meet a daily income target that will enable the Fund to, in turn, achieve the Annual Target, although there is no guarantee that the Fund will be able to achieve its Annual Target.
This strategy seeks to offer an “enhanced” yield compared to traditional option-based strategies by focusing on short-term options, which typically yield higher income than equivalent longer-term options.
In addition to options trading, the Fund will hold cash or short-term U.S. Treasury securities. These securities serve a dual purpose: providing collateral for the options strategy and contributing to the Fund’s income generation.
Dividends paid by the Fund’s Index ETF holdings will contribute to the Fund’s income generation.
The Fund’s options contracts will:
For more information, see the section “The Fund’s Use of Index Option Contracts” below.
Why invest in the Fund?
● The Fund seeks to generate monthly income at the Annual Target, which is not dependent on the value of the Index.
● The Fund seeks to participate in some of the potential gains experienced by increases in the value of the Index.
That is, although the Fund will not fully participate in gains in the value of the Index, the Fund’s portfolio is designed to generate income and benefit if the Index’s value increases above the call spreads cap (via its Index ETF holdings).
An investment in the Fund is not an investment in the Index, nor is the Fund an investment in a traditional passively managed index fund.
The Fund’s strategy is subject to all potential losses if the Index loses value, which may not be offset by income received by the Fund.
Additional information regarding the Index is also set forth below.
The Fund’s Use of Index Option Contracts
The Fund’s approach to Index option contracts entails selling daily Index credit call spreads. The Fund will earn net premium income, with an opportunity to gain from the time decay of options.
Fund Portfolio
The Fund’s portfolio is comprised mainly of:
The Fund intends to invest in cash-settled options, which means the holder of the option doesn’t receive securities when the option is exercised or expires. Instead, any payments are made in cash.
The Fund is classified as “non-diversified” under the 1940 Act.
Under normal circumstances, the Fund will invest at least 80% of the value of its net assets, plus borrowings for investment purposes, in financial instruments and economic interests that provide exposure to the value of the Index. For purposes of compliance with this investment policy, derivative contracts will be valued at their notional value.
THE FUND, TRUST, ADVISER, AND SUB-ADVISER ARE NOT AFFILIATED WITH, NOR ENDORSED BY, THE INDEX.
Index Overview: The S&P 500 Index is a widely recognized benchmark index that tracks the performance of 500 of the largest U.S.-based companies listed on the New York Stock Exchange or Nasdaq. These companies represent approximately 80% of the total U.S. equities market by capitalization, making it a large-cap index.
The S&P 500 is diversified across all sectors of the economy, including technology, healthcare, consumer discretionary, financials, industrials, and others. This distribution can vary over time as the market value of the sectors change.
Regarding volatility, the S&P 500, like all market indices, has experienced periods of significant daily price movements. Historically notable periods of volatility include the Black Monday crash in 1987, the dot-com bubble burst around 2000, the financial crisis of 2008, and the market reactions to the COVID-19 pandemic in early 2020. However, the specific degree of volatility can vary and is subject to change based on overall market conditions. Despite these periods of volatility, the Index has shown long-term growth over its history.

| Risk [Text Block] | rr_RiskTextBlock | Derivatives Risk. Derivatives are financial instruments that derive value from the underlying reference asset or assets, such as stocks, bonds, or funds (including ETFs), interest rates or indexes. The Fund’s investments in derivatives may pose risks in addition to, and greater than, those associated with directly investing in securities or other ordinary investments, including risk related to the market, imperfect correlation with underlying investments, higher price volatility, lack of availability, counterparty risk, liquidity, valuation and legal restrictions. The use of derivatives is a highly specialized activity that involves investment techniques and risks different from those associated with ordinary portfolio securities transactions. The use of derivatives may result in larger losses or smaller gains than directly investing in securities. When the Fund uses derivatives, there may be an imperfect correlation between the value of the Index and the derivative, which may prevent the Fund from achieving its investment objective. Because derivatives often require only a limited initial investment, the use of derivatives may expose the Fund to losses in excess of those amounts initially invested. In addition, the Fund’s investments in derivatives are subject to the following risks:

| Risk [Text Block] | rr_RiskTextBlock | Options Contracts. The use of options contracts involves investment strategies and risks different from those associated with ordinary portfolio securities transactions. The prices of options are volatile and are influenced by, among other things, actual and anticipated changes in the value of the underlying instrument, including the anticipated volatility, which are affected by fiscal and monetary policies and by national and international political, changes in the actual or implied volatility or the reference asset, the time remaining until the expiration of the option contract and economic events. For the Fund in particular, the value of the options contracts in which it invests are substantially influenced by the value of the Index. The Fund may experience substantial downside from specific option positions and certain option positions held by the Fund may expire worthless. The options held by the Fund are exercisable at the strike price on their expiration date. As an option approaches its expiration date, its value typically increasingly moves with the value of the underlying instrument. However, prior to such date, the value of an option generally does not increase or decrease at the same rate at the underlying instrument. There may at times be an imperfect correlation between the movement in values options contracts and the underlying instrument, and there may at times not be a liquid secondary market for certain options contracts. The value of the options held by the Fund will be determined based on market quotations or other recognized pricing methods.

Since the Fund is not a member of clearing houses and only members of a clearing house (“clearing members”) can participate directly in the clearing house, the Fund will hold cleared derivatives through accounts at clearing members. In cleared derivatives positions, the Fund will make payments (including margin payments) to and receive payments from a clearing house through their accounts at clearing members. Customer funds held at a clearing organization in connection with any options 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 options 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 clearing house, there is a risk that the assets of the Fund might not be fully protected in the event of the clearing member’s bankruptcy, as the Fund would be limited to recovering only a pro rata share of all available funds segregated on behalf of the clearing member’s customers for the relevant account class. 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. 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.

| Risk [Text Block] | rr_RiskTextBlock | Distribution Risk. As part of the Fund’s investment objective to provide current income, the Fund seeks to provide monthly income distributions. There is no assurance that the Fund will make a distribution in any given month. If the Fund does make distributions, the amounts of such distributions will likely vary greatly from one distribution to the next. Additionally, the monthly distributions, if any, may consist of returns of capital, which would decrease the Fund’s NAV and trading price over time. As a result, an investor may suffer significant losses to their investment.

| Risk [Text Block] | rr_RiskTextBlock | NAV Erosion Risk Due to Distributions. When the Fund makes a distribution, the Fund’s NAV will typically drop by the amount of the distribution on the related ex-dividend date (i.e., the date by which you need to own a dividend-paying stock in order to receive the upcoming dividend payment). The repeated payment of distributions by the Fund, if any, may significantly erode the Fund’s NAV and trading price over time. As a result, an investor may suffer significant losses to their investment.

The Fund has a limited number of financial institutions that are authorized to purchase and redeem Shares directly from the Fund (known as “Authorized Participants” or “APs”). In addition, there may be a limited number of market makers and/or liquidity providers in the marketplace. To the extent either of the following events occur, Shares may trade at a material discount to NAV and possibly face delisting: (i) APs exit the business or otherwise become unable to process creation and/or redemption orders and no other APs step forward to perform these services; or (ii) market makers and/or liquidity providers exit the business or significantly reduce their business activities and no other entities step forward to perform their functions.

| Risk [Text Block] | rr_RiskTextBlock | Cash Redemption Risk. The Fund’s investment strategy may require it to redeem Shares for cash or to otherwise include cash as part of its redemption proceeds. For example, the Fund may not be able to redeem in-kind certain securities held by the Fund (e.g., derivative instruments). In such a case, the Fund may be required to sell or unwind portfolio investments to obtain the cash needed to distribute redemption proceeds. This may cause the Fund to recognize a capital gain that it might not have recognized if it had made a redemption in-kind. As a result, the Fund may pay out higher annual capital gain distributions than if the in-kind redemption process was used. By paying out higher annual capital gain distributions, investors may be subjected to increased capital gains taxes. Additionally, there may be brokerage costs or taxable gains or losses that may be imposed on the Fund in connection with a cash redemption that may not have occurred if the Fund had made a redemption in-kind. These costs could decrease the value of the Fund to the extent they are not offset by a transaction fee payable by an AP.

| Risk [Text Block] | rr_RiskTextBlock | Trading. Although Shares are listed on a national securities exchange, such as NYSE Arca, Inc. (the “Exchange”), and may be traded on U.S. exchanges other than the Exchange, there can be no assurance that an active trading market for the Shares will develop or be maintained or that the Shares will trade with any volume, or at all, on any stock exchange. This risk may be greater for the Fund as it seeks to have exposure to a single underlying stock as opposed to a more diverse portfolio like a traditional pooled investment. In stressed market conditions, the liquidity of Shares may begin to mirror the liquidity of the Fund’s underlying portfolio holdings, which can be significantly less liquid than Shares. Shares trade on the Exchange at a market price that may be below, at or above the Fund’s NAV. Trading in Shares on the Exchange may be halted due to market conditions or for reasons that, in the view of the Exchange, make trading in Shares inadvisable. In addition, trading in Shares on the Exchange is subject to trading halts caused by extraordinary market volatility pursuant to the Exchange “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. In the event of an unscheduled market close for options contracts that reference a single stock, such as the Index’s securities being halted or a market wide closure, settlement prices will be determined by the procedures of the listing exchange of the options contracts. As a result, the Fund could be adversely affected and be unable to implement its investment strategies in the event of an unscheduled closing.

| Risk [Text Block] | rr_RiskTextBlock | Liquidity Risk. Some securities held by the Fund, including options contracts, may be difficult to sell or be illiquid, particularly during times of market turmoil. This risk is greater for the Fund as it will hold options contracts on a single security, and not a broader range of options contracts. Markets for securities or financial instruments could be disrupted by a number of events, including, but not limited to, an economic crisis, natural disasters, epidemics/pandemics, new legislation or regulatory changes inside or outside the United States. Illiquid securities may be difficult to value, especially in changing or volatile markets. If the Fund is forced to sell an illiquid security at an unfavorable time or price, the Fund may be adversely impacted. Certain market conditions or restrictions, such as market rules related to short sales, may prevent the Fund from limiting losses, realizing gains or achieving a high correlation with the Index. There is no assurance that a security that is deemed liquid when purchased will continue to be liquid. Market illiquidity may cause losses for the Fund.

| Risk [Text Block] | rr_RiskTextBlock | Market Events Risk. The Fund’s investments are subject to changes in general economic conditions, general market fluctuations and the risks inherent in investment in securities and other financial instruments. Investment markets can be volatile and prices of investments can change substantially due to various factors including, but not limited to, economic growth or recession, changes in interest rates, inflation, changes in the actual or perceived creditworthiness of issuers, and general market liquidity. The Fund is subject to the risk that geopolitical events will disrupt securities and other financial markets and adversely affect global economies and markets. Local, regional or global events such as war, military conflicts, acts of terrorism, natural disasters, the spread of infectious illness or other public health issues, or other events could have a significant impact on the Fund and its investments. Continuing uncertainties regarding interest rates, rising inflation, political events, rising government debt in the U.S. and trade tensions also contribute to market volatility. Conflict, loss of life and disaster connected to ongoing armed conflict between Ukraine and Russia in Europe and between Israel and Hamas in the Middle East could have severe adverse effects on the related region, including significant adverse effects on the regional or global economies and the markets for certain securities. The U.S. and the European Union have imposed sanctions on certain Russian individuals and companies, including certain financial institutions, and have limited certain exports and imports to and from Russia. These conflicts have contributed to recent market volatility and may continue to do so.

Because the Fund is “non-diversified,” it may invest a greater percentage of its assets in the securities of a single issuer or a smaller number of issuers than if it was a diversified fund. As a result, a decline in the value of an investment in a single issuer or a smaller number of issuers could cause the Fund’s overall value to decline to a greater degree than if the Fund held a more diversified portfolio. This may increase the Fund’s volatility and cause the performance of a relatively smaller number of issuers to have a greater impact on the Fund’s performance.

| Strategy [Heading] | rr_StrategyHeading | Principal Investment Strategies | |||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||
| Strategy Narrative [Text Block] | rr_StrategyNarrativeTextBlock | The Fund is an actively managed exchange-traded fund (“ETF”) that primarily seeks to generate current income. The Fund’s strategy involves holding shares of unaffiliated passively managed ETFs that seek to track the performance of the Index (“Index ETFs”) and selling daily credit call spreads on the Index. The Fund’s daily credit call spread strategy consists of selling a call option and simultaneously buying another call option at a higher strike price for income generation.
The Fund’s investment approach is designed to generate income through option premiums derived from selling Index call spreads, which will be the primary driver of the Fund’s yield. To retain upside growth potential (if the value of the Index increases) and seek a target annual income level of 20% (the “Annual Target”), the Fund sells at-the-money or near-the-money call spreads. The sold call spreads generate premium and also allow the Fund to benefit if the Index’s value increases above the call spreads cap (described below) via its Index ETF holdings. Additionally, the Fund will maintain a minor allocation to cash or U.S. Treasuries, not exceeding ten percent of its total assets.
The Fund will employ its investment strategy regardless of fluctuating market, economic, or other conditions, and will not seek to take temporary defensive positions during such periods. Each day, the Fund will sell Index call spreads to generate net income from the options premiums. These spreads will be designed to seek the Annual Target level of income while maintaining exposure to the value of the Index.
Each day, the Fund will sell credit call spreads on the Index, focusing on options with near-term expiration. This involves selling call options at a strike price at or near the money and buying call options above that strike price. If the Index’s value rises above the upper strike price (the call spreads cap), the Fund will profit from further upside appreciation in the value of the Index.
The Fund aims for consistent monthly distributions, primarily relying on the income generated from selling the call spreads. If the anticipated daily income from these activities surpasses a set threshold, ZEGA Financial, LLC (Sub-Adviser), may adjust the strategy to seek to meet a daily income target that will enable the Fund to, in turn, achieve the Annual Target, although there is no guarantee that the Fund will be able to achieve its Annual Target.
This strategy seeks to offer an “enhanced” yield compared to traditional option-based strategies by focusing on short-term options, which typically yield higher income than equivalent longer-term options.
In addition to options trading, the Fund will hold cash or short-term U.S. Treasury securities. These securities serve a dual purpose: providing collateral for the options strategy and contributing to the Fund’s income generation.
Dividends paid by the Fund’s Index ETF holdings will contribute to the Fund’s income generation.
The Fund’s options contracts will:
For more information, see the section “The Fund’s Use of Index Option Contracts” below.
Why invest in the Fund?
● The Fund seeks to generate monthly income at the Annual Target, which is not dependent on the value of the Index.
● The Fund seeks to participate in some of the potential gains experienced by increases in the value of the Index.
That is, although the Fund will not fully participate in gains in the value of the Index, the Fund’s portfolio is designed to generate income and benefit if the Index’s value increases above the call spreads cap (via its Index ETF holdings).
An investment in the Fund is not an investment in the Index, nor is the Fund an investment in a traditional passively managed index fund.
The Fund’s strategy is subject to all potential losses if the Index loses value, which may not be offset by income received by the Fund.
Additional information regarding the Index is also set forth below.
The Fund’s Use of Index Option Contracts
The Fund’s approach to Index option contracts entails selling daily Index credit call spreads. The Fund will earn net premium income, with an opportunity to gain from the time decay of options.
Fund Portfolio
The Fund’s portfolio is comprised mainly of:
The Fund intends to invest in cash-settled options, which means the holder of the option doesn’t receive securities when the option is exercised or expires. Instead, any payments are made in cash.
The Fund is classified as “non-diversified” under the 1940 Act.
Under normal circumstances, the Fund will invest at least 80% of the value of its net assets, plus borrowings for investment purposes, in financial instruments and economic interests that provide exposure to the value of the Index. For purposes of compliance with this investment policy, derivative contracts will be valued at their notional value.
There is no guarantee that the Fund’s investment strategy will be properly implemented, and an investor may lose some or all of its investment.
None of the Fund, the Trust, the Adviser, the Sub-Adviser, or their respective affiliates makes any representation to you as to the performance of the Index.
THE FUND, TRUST, ADVISER, AND SUB-ADVISER ARE NOT AFFILIATED WITH, NOR ENDORSED BY, THE INDEX.
Index Overview: The Russell 2000 Index is a widely recognized benchmark index that tracks the performance of approximately 2000 small-cap companies in the United States. These are the smallest companies listed in the Russell 3000 Index, representing about 10% of that index’s total market capitalization.
The Russell 2000 Index is diversified and includes companies from various sectors such as financial services, healthcare, technology, consumer discretionary, industrials, and others. The exact distribution can fluctuate over time due to market conditions.
In terms of volatility, the Index, being a small-cap index, tends to be more volatile than large-cap indices like the S&P 500 or the Nasdaq 100 indices. Small-cap stocks can be more sensitive to changes in the economic climate and can experience larger price swings. Notable periods of volatility have included the dot-com bubble burst in 2000, the financial crisis in 2008, and the market turmoil caused by the COVID-19 pandemic in 2020. However, as with any index, the specific level of volatility can change based on broader market conditions.

| Risk [Text Block] | rr_RiskTextBlock | Derivatives Risk. Derivatives are financial instruments that derive value from the underlying reference asset or assets, such as stocks, bonds, or funds (including ETFs), interest rates or indexes. The Fund’s investments in derivatives may pose risks in addition to, and greater than, those associated with directly investing in securities or other ordinary investments, including risk related to the market, imperfect correlation with underlying investments, higher price volatility, lack of availability, counterparty risk, liquidity, valuation and legal restrictions. The use of derivatives is a highly specialized activity that involves investment techniques and risks different from those associated with ordinary portfolio securities transactions. The use of derivatives may result in larger losses or smaller gains than directly investing in securities. When the Fund uses derivatives, there may be an imperfect correlation between the value of the Index and the derivative, which may prevent the Fund from achieving its investment objective. Because derivatives often require only a limited initial investment, the use of derivatives may expose the Fund to losses in excess of those amounts initially invested. In addition, the Fund’s investments in derivatives are subject to the following risks:

| Prospectus [Line Items] | rr_ProspectusLineItems | ||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||
| Risk [Text Block] | rr_RiskTextBlock | Options Contracts. The use of options contracts involves investment strategies and risks different from those associated with ordinary portfolio securities transactions. The prices of options are volatile and are influenced by, among other things, actual and anticipated changes in the value of the underlying instrument, including the anticipated volatility, which are affected by fiscal and monetary policies and by national and international political, changes in the actual or implied volatility or the reference asset, the time remaining until the expiration of the option contract and economic events. For the Fund in particular, the value of the options contracts in which it invests are substantially influenced by the value of the Index. The Fund may experience substantial downside from specific option positions and certain option positions held by the Fund may expire worthless. The options held by the Fund are exercisable at the strike price on their expiration date. As an option approaches its expiration date, its value typically increasingly moves with the value of the underlying instrument. However, prior to such date, the value of an option generally does not increase or decrease at the same rate at the underlying instrument. There may at times be an imperfect correlation between the movement in values options contracts and the underlying instrument, and there may at times not be a liquid secondary market for certain options contracts. The value of the options held by the Fund will be determined based on market quotations or other recognized pricing methods.

| Prospectus [Line Items] | rr_ProspectusLineItems | ||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||
| Risk [Text Block] | rr_RiskTextBlock | Counterparty Risk. The Fund is subject to counterparty risk by virtue of its investments in options contracts. Transactions in some types of derivatives, including options, are required to be centrally cleared (“cleared derivatives”). In a transaction involving cleared derivatives, the Fund’s counterparty is a clearing house rather than a bank or broker. Since the Fund is not a member of clearing houses and only members of a clearing house (“clearing members”) can participate directly in the clearing house, the Fund will hold cleared derivatives through accounts at clearing members. In cleared derivatives positions, the Fund will make payments (including margin payments) to and receive payments from a clearing house through their accounts at clearing members. Customer funds held at a clearing organization in connection with any options 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 options 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 clearing house, there is a risk that the assets of the Fund might not be fully protected in the event of the clearing member’s bankruptcy, as the Fund would be limited to recovering only a pro rata share of all available funds segregated on behalf of the clearing member’s customers for the relevant account class. 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. 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.

| Risk [Text Block] | rr_RiskTextBlock | Distribution Risk. As part of the Fund’s investment objective to provide current income, the Fund seeks to provide monthly income distributions. There is no assurance that the Fund will make a distribution in any given month. If the Fund does make distributions, the amounts of such distributions will likely vary greatly from one distribution to the next. Additionally, the monthly distributions, if any, may consist of returns of capital, which would decrease the Fund’s NAV and trading price over time. As a result, an investor may suffer significant losses to their investment.

The repeated payment of distributions by the Fund, if any, may significantly erode the Fund’s NAV and trading price over time. As a result, an investor may suffer significant losses to their investment.

In addition, there may be a limited number of market makers and/or liquidity providers in the marketplace. To the extent either of the following events occur, Shares may trade at a material discount to NAV and possibly face delisting: (i) APs exit the business or otherwise become unable to process creation and/or redemption orders and no other APs step forward to perform these services; or (ii) market makers and/or liquidity providers exit the business or significantly reduce their business activities and no other entities step forward to perform their functions.

| Risk [Text Block] | rr_RiskTextBlock | Cash Redemption Risk. The Fund’s investment strategy may require it to redeem Shares for cash or to otherwise include cash as part of its redemption proceeds. For example, the Fund may not be able to redeem in-kind certain securities held by the Fund (e.g., derivative instruments). In such a case, the Fund may be required to sell or unwind portfolio investments to obtain the cash needed to distribute redemption proceeds. This may cause the Fund to recognize a capital gain that it might not have recognized if it had made a redemption in-kind. As a result, the Fund may pay out higher annual capital gain distributions than if the in-kind redemption process was used. By paying out higher annual capital gain distributions, investors may be subjected to increased capital gains taxes. Additionally, there may be brokerage costs or taxable gains or losses that may be imposed on the Fund in connection with a cash redemption that may not have occurred if the Fund had made a redemption in-kind. These costs could decrease the value of the Fund to the extent they are not offset by a transaction fee payable by an AP.

| Risk [Text Block] | rr_RiskTextBlock | Trading. Although Shares are listed on a national securities exchange, such as NYSE Arca, Inc. (the “Exchange”), and may be traded on U.S. exchanges other than the Exchange, there can be no assurance that an active trading market for the Shares will develop or be maintained or that the Shares will trade with any volume, or at all, on any stock exchange. This risk may be greater for the Fund as it seeks to have exposure to a single underlying stock as opposed to a more diverse portfolio like a traditional pooled investment. In stressed market conditions, the liquidity of Shares may begin to mirror the liquidity of the Fund’s underlying portfolio holdings, which can be significantly less liquid than Shares. Shares trade on the Exchange at a market price that may be below, at or above the Fund’s NAV. Trading in Shares on the Exchange may be halted due to market conditions or for reasons that, in the view of the Exchange, make trading in Shares inadvisable. In addition, trading in Shares on the Exchange is subject to trading halts caused by extraordinary market volatility pursuant to the Exchange “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. In the event of an unscheduled market close for options contracts that reference a single stock, such as the Index’s securities being halted or a market wide closure, settlement prices will be determined by the procedures of the listing exchange of the options contracts. As a result, the Fund could be adversely affected and be unable to implement its investment strategies in the event of an unscheduled closing.

| Risk [Text Block] | rr_RiskTextBlock | Liquidity Risk. Some securities held by the Fund, including options contracts, may be difficult to sell or be illiquid, particularly during times of market turmoil. This risk is greater for the Fund as it will hold options contracts on a single security, and not a broader range of options contracts. Markets for securities or financial instruments could be disrupted by a number of events, including, but not limited to, an economic crisis, natural disasters, epidemics/pandemics, new legislation or regulatory changes inside or outside the United States. Illiquid securities may be difficult to value, especially in changing or volatile markets. If the Fund is forced to sell an illiquid security at an unfavorable time or price, the Fund may be adversely impacted. Certain market conditions or restrictions, such as market rules related to short sales, may prevent the Fund from limiting losses, realizing gains or achieving a high correlation with the Index. There is no assurance that a security that is deemed liquid when purchased will continue to be liquid. Market illiquidity may cause losses for the Fund.

| Risk [Text Block] | rr_RiskTextBlock | Market Events Risk. The Fund’s investments are subject to changes in general economic conditions, general market fluctuations and the risks inherent in investment in securities and other financial instruments. Investment markets can be volatile and prices of investments can change substantially due to various factors including, but not limited to, economic growth or recession, changes in interest rates, inflation, changes in the actual or perceived creditworthiness of issuers, and general market liquidity. The Fund is subject to the risk that geopolitical events will disrupt securities and other financial markets and adversely affect global economies and markets. Local, regional or global events such as war, military conflicts, acts of terrorism, natural disasters, the spread of infectious illness or other public health issues, or other events could have a significant impact on the Fund and its investments. Continuing uncertainties regarding interest rates, rising inflation, political events, rising government debt in the U.S. and trade tensions also contribute to market volatility. Conflict, loss of life and disaster connected to ongoing armed conflict between Ukraine and Russia in Europe and between Israel and Hamas in the Middle East could have severe adverse effects on the related region, including significant adverse effects on the regional or global economies and the markets for certain securities. The U.S. and the European Union have imposed sanctions on certain Russian individuals and companies, including certain financial institutions, and have limited certain exports and imports to and from Russia. These conflicts have contributed to recent market volatility and may continue to do so.

| Risk [Text Block] | rr_RiskTextBlock | Non-Diversification Risk. Because the Fund is “non-diversified,” it may invest a greater percentage of its assets in the securities of a single issuer or a smaller number of issuers than if it was a diversified fund. As a result, a decline in the value of an investment in a single issuer or a smaller number of issuers could cause the Fund’s overall value to decline to a greater degree than if the Fund held a more diversified portfolio.

| Strategy [Heading] | rr_StrategyHeading | Principal Investment Strategies | |||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||
| Strategy Narrative [Text Block] | rr_StrategyNarrativeTextBlock | The Fund is an actively managed exchange-traded fund (“ETF”) that seeks current income while maintaining the opportunity for indirect exposure to the share price of SPDR Gold Shares (“GLD” or the “Underlying ETP”), subject to a limit on potential gains related to increases in the price of GLD’s shares. While maintaining indirect exposure to the Underlying ETP, the Fund aims to generate additional income from its options investments when GLD’s share price rises, based on the specific put options it sold.
GLD is an exchange-traded product (“ETP”) that generally seeks to replicate the performance of the price of gold bullion. GLD is not subject to the protections of the 1940 Act; however, the Fund and its shareholders are subject to the protections of the 1940 Act.
The Fund will not seek to invest directly in the ETP, however, due to the non-cash settlement nature of the fund’s options strategy, the Fund may be required from time to time to hold shares of the ETP. In such a case, the Fund will generally seek to sell such ETP holding the same day (to avoid adverse tax consequences to the Fund). As further described below, at least once a week, the Fund uses an at-the-money or in-the-money put option selling strategy to provide income and exposure to the price of the Underlying ETP shares, subject to a limit on potential investment gains as a result of the nature of the options strategy it employs. The Fund’s options contracts provide current income from the premium it receives from the sale of such options contracts and a limit on the Fund’s indirect participation in gains, if any, of the increase in the price of the Underlying ETP’s shares. In addition, the Fund’s in-the-money put options will provide some upside appreciation, also known as “intrinsic value.” As discussed in greater detail below, the Fund will not directly or fully participate in gains experienced by the Underlying ETP. Please see “Additional Information about the Fund” below for a description of options terminology.
At least once a week, the Fund will sell put options that are priced either at-the-money or up to five percent in-the-money (i.e., higher than the current market price). If the Fund sells an option that’s priced above the current market price, the Fund may profit if the Underlying ETP’s share price increases above its current price, stays flat, or decreases slightly (i.e., the decrease to the Fund is less than the original extrinsic premium received). This opportunity exists until the option’s expiration date, which is typically one week or less (as of the date of this prospectus, options expire each Wednesday and Friday). In other words, the Fund’s potential for profit (or exposure) fluctuates. The Fund will initially use only European FLexible EXchange® (“FLEX”) options, but may also use options that are exercisable at any time (i.e. American style options contracts).
The Fund’s strategy focuses on having the ability to make monthly distributions through generating income throughout each week by regularly selling put options. Simultaneously, it aims to provide an “enhanced” yield compared to traditional option-based strategies by frequently selling short-term options, typically with a duration of less than a week. This method may result in higher income than with an approach of selling longer-term options over the same period, although there is no guarantee such an approach will result in higher income.
The Fund’s options contracts provide:
For more information, see the section “The Fund’s Use of Underlying ETP Option Contracts” below.
In addition to its options investments, the Fund will hold short-term U.S. Treasury securities for collateral for the options and to generate additional income for the Fund.
The Fund’s investment adviser is Tidal Investments LLC (the “Adviser”) and the investment sub-adviser is ZEGA Financial, LLC (the “Sub-Adviser”).
Why invest in the Fund?
● The Fund seeks to generate monthly income through its options strategy, which is not dependent on the price appreciation of the Underlying ETP’s shares. ● The Fund seeks to indirectly participate in a portion of the potential gains experienced by increases in the Underlying ETP’s shares (via income from its options holdings).
That is, although the Fund’s income gains related to gains in the Underlying ETP’s shares will be capped, the Fund’s portfolio is designed to generate income.
An Investment in the Fund is not an investment in GLD, nor in gold bullion.
Additional information regarding GLD is set forth below.
The Fund’s Use of the Underlying ETP Option Contracts
Throughout each week, the Fund will sell at-the-money or in-the-money puts on the Underlying ETP. In particular, the Fund will sell puts with near-term expirations at a range of 0% to 5% “in-the-money” (i.e., where the strike price is above the current price of the Underlying ETP’s shares by between 0% and 5%). The Fund will receive premium income for each put sold. In addition, the strategy will provide the Fund with the opportunity to earn both time decay (described below) and, for in-the-money puts, a limited amount of upside appreciation up to the puts’ strike price (described below) plus the puts’ intrinsic value. The expiration dates at the time of purchase for the Fund’s sold puts will range from one day to a month (“Call Period”). The Fund’s participation in potential increases in the price of the Underlying ETP’s shares is based on the price of the Underlying ETP’s shares at the time the Fund sells a put option contract and the Underlying ETP’s share price at the time of the contract’s expiration.
For example, imagine the Underlying ETP’s shares are priced at $200, and a put option with a strike price of 205 is sold for $15. The difference between the strike price and the Underlying ETP’s share price is $5 (in-the-money amount). The remaining $10 (the $15 put price minus the $5 in-the-money amount) represents the put’s extrinsic value. In the case of this example:
As of the date of this prospectus, the available options are non-cash-settled. As a result, theoretically, the Fund would be obligated to receive shares of the Underlying ETP when the option was exercised. Consequently, there is a risk that the Fund may have to physically acquire the Underlying ETP shares at the strike price, which could result in the Fund holding the Underlying ETP’s share, and an asset that has declined in value. However, in such instances, the Fund will seek to avoid owning shares of the Underlying ETP by trading out of the puts prior to expiration or selling the delivered shares immediately upon receipt.
When selling put options, the Fund will generally be subject to different outcomes based on market movements and whether the options sold are at-the-money or in-the-money. Such outcomes may or may not be profitable to the Fund, depending on the circumstances, and there is no guarantee that any given situation will occur and be profitable to the Fund:
U.S. Treasuries
The Fund will hold short-term U.S. Treasury securities as collateral in connection with the Fund’s options strategy and to generate income.
Fund’s Monthly Distributions
The Fund will seek to provide monthly income in the form of cash distributions. The Fund will seek to generate such income in the following two ways:
Fund’s Return Profile vs. the Underlying ETP
For the reasons stated above, the Fund’s performance will differ from that of the Underlying ETP’s share prices. The performance differences will depend on, among other things, the price of the Underlying ETP’s shares, changes in the value of the Underlying ETP put options contracts the Fund has sold, and changes in the value of the U.S. Treasuries.
The Fund’s strategy is designed to have unleveraged, 100% downside notional exposure (as described below) to the Underlying ETP. Essentially, the assignment value of the put options that the Fund invests in will match the value as if the Fund had directly purchased the Underlying ETP’s shares.
Let’s consider a scenario where the Fund has assets totaling $10 million and the Underlying ETP is priced at 200. In this instance, the number of contracts would be 500. We calculate this by dividing the Fund’s value by the value of one contract. Here, $10,000,000 divided by $20,000 (obtained by multiplying the Underlying ETP’s share price of 200 by the standard multiplier of 100) gives us 500.
However, the Fund’s notional exposure, representing the theoretical exposure of its portfolio, will drift daily due to various factors such as market movements and changes in option prices. Notional value is calculated based on the quantity of assets underlying the options positions, multiplied by the strike price of the option. The Fund may reallocate its portfolio upon entering a new position at the option’s expiration. In this process, the Fund will allow its currently held options to expire, close them, or roll (closing out of existing options contracts to purchase new options contracts) them early. Subsequently, the Fund enters new put options positions when the existing ones have expired, been closed, or been rolled early. The Fund may allow the options to expire worthless in order to reduce execution costs and minimize trading drift.
Fund Portfolio
The Fund’s principal holdings are described below:
To fully collateralize the Fund’s options strategy, the market value of the cash and treasuries held by the Fund is expected to comprise at least 80% of the Fund’s net assets and the market value of the options is expected to be between 0% and 10% of the Fund’s net assets. The combination of these investments provides investment exposure to GLD such that the notional exposure is equal to 100% of the Fund’s total assets. The “notional exposure” is the return on or change in value of a particular dollar amount representing the underlying investment. The notional value and the market value both describe the value of a security. Notional value speaks to how much total value a security theoretically controls – for instance through options contracts. Market value, on the other hand, is the price of a security right now that can be bought and sold on an exchange or through a broker.
As a result of the Fund’s investment strategy, it may experience a high portfolio turnover rate.
The Fund is classified as “non-diversified” under the 1940 Act.
Under normal circumstances, the Fund will invest at least 80% of the value of its net assets, plus borrowings for investment purposes, in financial instruments and economic interests that provide exposure to the value of the Underlying ETP shares. For purposes of compliance with this investment policy, derivative contracts will be valued at their notional value.
There is no guarantee that the Fund’s investment strategy will be properly implemented, and an investor may lose some or all of its investment.

| Risk [Text Block] | rr_RiskTextBlock | Derivatives Risk. Derivatives are financial instruments that derive value from the underlying reference asset or assets, such as stocks, bonds, or funds (including ETFs and ETPs), interest rates or indexes. The Fund’s investments in derivatives may pose risks in addition to, and greater than, those associated with directly investing in securities or other ordinary investments, including risk related to the market, imperfect correlation with underlying investments, higher price volatility, lack of availability, counterparty risk, liquidity, valuation and legal restrictions. The use of derivatives is a highly specialized activity that involves investment techniques and risks different from those associated with ordinary portfolio securities transactions. The use of derivatives may result in larger losses or smaller gains than directly investing in securities. When the Fund uses derivatives, there may be an imperfect correlation between the value of the Underlying ETP and the derivative, which may prevent the Fund from achieving its investment objectives. Because derivatives often require only a limited initial investment, the use of derivatives may expose the Fund to losses in excess of those amounts initially invested. In addition, the Fund’s investments in derivatives are subject to the following risks:

| Prospectus [Line Items] | rr_ProspectusLineItems | ||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||
| Risk [Text Block] | rr_RiskTextBlock | Options Contracts. The use of options contracts involves investment strategies and risks different from those associated with ordinary portfolio securities transactions. The prices of options are volatile and are influenced by, among other things, actual and anticipated changes in the value of the underlying instrument, including the anticipated volatility, which are affected by fiscal and monetary policies and by national and international political, changes in the actual or implied volatility or the reference asset, the time remaining until the expiration of the option contract and economic events. For the Fund, in particular, the value of the options contracts in which it invests is substantially influenced by the value of the Underlying ETP. Selling put options exposes the Fund to the risk of potential loss if the market value of the Underlying ETP falls below the strike price before the option expires. The Fund may experience substantial downside from specific option positions and certain option positions held by the Fund may expire worthless. The options held by the Fund are exercisable at the strike price on their expiration date. As an option approaches its expiration date, its value typically increasingly moves with the value of the underlying instrument. However, prior to such date, the value of an option generally does not increase or decrease at the same rate at the underlying instrument. There may at times be an imperfect correlation between the movement in values options contracts and the underlying instrument, and there may at times not be a liquid secondary market for certain options contracts. The value of the options held by the Fund will be determined based on market quotations or other recognized pricing methods. Additionally, the Fund’s practice of rolling may cause the Fund to experience losses if the expiring contracts do not generate proceeds enough to cover the costs of entering into new options contracts. Further, if an option is exercised, the seller (writer) of a put option is obligated to purchase the underlying asset at the strike price, which can result in significant financial and regulatory obligations for the Fund if the market value of the asset has fallen substantially. Furthermore, when the Fund seeks to trade out of puts, especially near expiration, there is an added risk that the Fund may be required to allocate resources unexpectedly to fulfill these obligations. This potential exposure to physical settlement can significantly impact the Fund’s liquidity and market exposure, particularly in volatile market conditions.

| Prospectus [Line Items] | rr_ProspectusLineItems | ||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||
| Risk [Text Block] | rr_RiskTextBlock | Counterparty Risk. The Fund is subject to counterparty risk by virtue of its investments in options contracts. Transactions in some types of derivatives, including options, are required to be centrally cleared (“cleared derivatives”). In a transaction involving cleared derivatives, the Fund’s counterparty is a clearing house rather than a bank or broker. Since the Fund is not a member of clearing houses and only members of a clearing house (“clearing members”) can participate directly in the clearing house, the Fund will hold cleared derivatives through accounts at clearing members. In cleared derivatives positions, the Fund will make payments (including margin payments) to and receive payments from a clearing house through their accounts at clearing members. Customer funds held at a clearing organization in connection with any options 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 options 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 clearing house, there is a risk that the assets of the Fund might not be fully protected in the event of the clearing member’s bankruptcy, as the Fund would be limited to recovering only a pro rata share of all available funds segregated on behalf of the clearing member’s customers for the relevant account class. 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. 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.

| Prospectus [Line Items] | rr_ProspectusLineItems | ||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||
| Risk [Text Block] | rr_RiskTextBlock | Price Participation Risk. The Fund employs an investment strategy that includes the sale of in-the-money put option contracts, which limits the degree to which the Fund will participate in increases in value experienced by the Underlying ETP over the Call Period (typically, one week, but may range from one day to a month). This means that if the Underlying ETP experiences an increase in value above the strike price of the sold put options during a Call Period, the Fund will likely not experience that increase to the same extent and may significantly underperform the Underlying ETP over the Call Period. Additionally, because the Fund is limited in the degree to which it will participate in increases in value experienced by the Underlying ETP over each Call Period, but has full exposure to any decreases in value experienced by the Underlying ETP over the Call Period, the NAV of the Fund may decrease over any given time period. The Fund’s NAV is dependent on the value of each options portfolio, which is based principally upon the performance of the Underlying ETP. The degree of participation in the Underlying ETP gains the Fund will experience will depend on prevailing market conditions, especially market volatility, at the time the Fund enters into the sold put option contracts and will vary from Call Period to Call Period. The value of the options contracts is affected by changes in the value and dividend rates of the Underlying ETP, changes in interest rates, changes in the actual or perceived volatility of the Underlying ETP and the remaining time to the options’ expiration, as well as trading conditions in the options market. As the price of the Underlying ETP changes and time moves towards the expiration of each Call Period, the value of the options contracts, and therefore the Fund’s NAV, will change. However, it is not expected for the Fund’s NAV to directly correlate on a day-to-day basis with the returns of the Underlying ETP. The amount of time remaining until the options contract’s expiration date affects the impact of the potential options contract income on the Fund’s NAV, which may not be in full effect until the expiration date of the Fund’s options contracts. Therefore, while changes in the price of the Underlying ETP will result in changes to the Fund’s NAV, the Fund generally anticipates that the rate of change in the Fund’s NAV will be different than that experienced by the Underlying ETP.

| Risk [Text Block] | rr_RiskTextBlock | Distribution Risk. As part of the Fund’s investment objective to provide current income, the Fund seeks to provide monthly income distributions. There is no assurance that the Fund will make a distribution in any given month. If the Fund does make distributions, the amounts of such distributions will likely vary greatly from one distribution to the next. Additionally, the monthly distributions, if any, may consist of returns of capital, which would decrease the Fund’s NAV and trading price over time. As a result, an investor may suffer significant losses to their investment.

| Prospectus [Line Items] | rr_ProspectusLineItems | ||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||
| Risk [Text Block] | rr_RiskTextBlock | NAV Erosion Risk Due to Distributions. When the Fund makes a distribution, the Fund’s NAV will typically drop by the amount of the distribution on the related ex-dividend date (i.e., the date by which you need to own a dividend-paying stock in order to receive the upcoming dividend payment). The repeated payment of distributions by the Fund, if any, may significantly erode the Fund’s NAV and trading price over time. As a result, an investor may suffer significant losses to their investment.

| Prospectus [Line Items] | rr_ProspectusLineItems | ||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||
| Risk [Text Block] | rr_RiskTextBlock | Put Writing Strategy Risk. The path dependency (i.e., the continued use) of the Fund’s put writing strategy will impact the extent that the Fund participates in the positive price returns of the Underlying ETP and, in turn, the Fund’s returns, both during the term of the sold put options and over longer time periods.
If, for example, the Fund were to sell 1% in-the-money put options having a one-week term, the Fund’s participation in the positive price returns of the Underlying ETP will be capped at 1% for that week. However, over a longer period (e.g., a four-week period), the Fund should not be expected to participate fully in the first 4% (i.e., 4 weeks x 1%) of the positive price returns of the Underlying ETP, or the Fund may even lose money, even if the Underlying ETP share price has appreciated by at least that much over such period, if during any particular week or weeks over that period the Underlying ETP had a return less than 1%. This example illustrates that both the Fund’s participation in the positive price returns of the Underlying ETP and its returns will depend not only on the price of the Underlying ETP but also on the path that the Underlying ETP takes over time.
Additionally, on a weekly basis, the Fund is generally fully exposed to the downward movements of the Underlying ETP, offset only by the premiums received from selling put contracts. The Fund does not seek to offer any downside protection, except for the fact that the premiums from the sold options may offset some or all of the Underlying ETP’s decline.

The Fund has a limited number of financial institutions that are authorized to purchase and redeem Shares directly from the Fund (known as “Authorized Participants” or “APs”). In addition, there may be a limited number of market makers and/or liquidity providers in the marketplace. To the extent either of the following events occur, Shares may trade at a material discount to NAV and possibly face delisting: (i) APs exit the business or otherwise become unable to process creation and/or redemption orders and no other APs step forward to perform these services; or (ii) market makers and/or liquidity providers exit the business or significantly reduce their business activities and no other entities step forward to perform their functions.

| Prospectus [Line Items] | rr_ProspectusLineItems | ||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||
| Risk [Text Block] | rr_RiskTextBlock | Cash Redemption Risk. The Fund’s investment strategy may require it to redeem Shares for cash or to otherwise include cash as part of its redemption proceeds. For example, the Fund may not be able to redeem in-kind certain securities held by the Fund (e.g., derivative instruments). In such a case, the Fund may be required to sell or unwind portfolio investments to obtain the cash needed to distribute redemption proceeds. This may cause the Fund to recognize a capital gain that it might not have recognized if it had made a redemption in-kind. As a result, the Fund may pay out higher annual capital gain distributions than if the in-kind redemption process was used. By paying out higher annual capital gain distributions, investors may be subjected to increased capital gains taxes. Additionally, there may be brokerage costs or taxable gains or losses that may be imposed on the Fund in connection with a cash redemption that may not have occurred if the Fund had made a redemption in-kind. These costs could decrease the value of the Fund to the extent they are not offset by a transaction fee payable by an AP.

| Risk [Text Block] | rr_RiskTextBlock | Trading. Although Shares are listed on a national securities exchange, such as The Nasdaq Stock Market, LLC (the “Exchange”), and may be traded on U.S. exchanges other than the Exchange, there can be no assurance that an active trading market for the Shares will develop or be maintained or that the Shares will trade with any volume, or at all, on any stock exchange. This risk may be greater for the Fund as it seeks to have exposure to a single underlying stock as opposed to a more diverse portfolio like a traditional pooled investment. In stressed market conditions, the liquidity of Shares may begin to mirror the liquidity of the Fund’s underlying portfolio holdings, which can be significantly less liquid than Shares. Shares trade on the Exchange at a market price that may be below, at or above the Fund’s NAV. Trading in Shares on the Exchange may be halted due to market conditions or for reasons that, in the view of the Exchange, make trading in Shares inadvisable. In addition, trading in Shares on the Exchange is subject to trading halts caused by extraordinary market volatility pursuant to the Exchange “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. In the event of an unscheduled market close for options contracts that reference a single stock, such as the Underlying ETP’s securities being halted or a market wide closure, settlement prices will be determined by the procedures of the listing exchange of the options contracts. As a result, the Fund could be adversely affected and be unable to implement its investment strategies in the event of an unscheduled closing.

| Risk [Text Block] | rr_RiskTextBlock | Liquidity Risk. Some securities held by the Fund, including options contracts, may be difficult to sell or be illiquid, particularly during times of market turmoil. This risk is greater for the Fund as it will hold options contracts on a single security, and not a broader range of options contracts. Markets for securities or financial instruments could be disrupted by a number of events, including, but not limited to, an economic crisis, natural disasters, epidemics/pandemics, new legislation or regulatory changes inside or outside the United States. Illiquid securities may be difficult to value, especially in changing or volatile markets. If the Fund is forced to sell an illiquid security at an unfavorable time or price, the Fund may be adversely impacted. Certain market conditions or restrictions, such as market rules related to short sales, may prevent the Fund from limiting losses, realizing gains or achieving a high correlation with the Underlying ETP. There is no assurance that a security that is deemed liquid when purchased will continue to be liquid. Market illiquidity may cause losses for the Fund.

| Risk [Text Block] | rr_RiskTextBlock | Market Events Risk. The Fund's investments are subject to changes in general economic conditions, general market fluctuations and the risks inherent in investment in securities and other financial instruments. Investment markets can be volatile and prices of investments can change substantially due to various factors including, but not limited to, economic growth or recession, changes in interest rates, inflation, changes in the actual or perceived creditworthiness of issuers, and general market liquidity. The Fund is subject to the risk that geopolitical events will disrupt securities and other financial markets and adversely affect global economies and markets. Local, regional or global events such as war, military conflicts, acts of terrorism, natural disasters, the spread of infectious illness or other public health issues, or other events could have a significant impact on the Fund and its investments. Continuing uncertainties regarding interest rates, rising inflation, political events, rising government debt in the U.S. and trade tensions also contribute to market volatility. Conflict, loss of life and disaster connected to ongoing armed conflict between Ukraine and Russia in Europe and between Israel and Hamas in the Middle East could have severe adverse effects on the related region, including significant adverse effects on the regional or global economies and the markets for certain securities. The U.S. and the European Union have imposed sanctions on certain Russian individuals and companies, including certain financial institutions, and have limited certain exports and imports to and from Russia. These conflicts have contributed to recent market volatility and may continue to do so.

| Risk [Text Block] | rr_RiskTextBlock | Non-Diversification Risk. Because the Fund is “non-diversified,” it may invest a greater percentage of its assets in the securities of a single issuer or a smaller number of issuers than if it was a diversified fund. As a result, a decline in the value of an investment in a single issuer or a smaller number of issuers could cause the Fund’s overall value to decline to a greater degree than if the Fund held a more diversified portfolio. This may increase the Fund’s volatility and cause the performance of a relatively smaller number of issuers to have a greater impact on the Fund’s performance.

| Risk [Text Block] | rr_RiskTextBlock | 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. To comply with the asset diversification test applicable to a RIC, the Fund will attempt to ensure that the value of options it holds is never 25% of the total value of Fund assets at the close of any quarter. If the Fund’s investments in options 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. In addition, distributions received by the Fund from the Underlying ETP may generate “bad income” that could prevent the Fund from meeting the “Income Requirement” of Subchapter M of the Code, which may cause the Fund to fail to qualify as a RIC.

This subjects the Fund to certain of the same risks as if it owned shares of GLD, even though it does not. By virtue of the Fund’s investments in options contracts that are based on the value of GLD, the Fund may also be subject to the following risks:

| Risk [Text Block] | rr_RiskTextBlock | GLD Trading Risk. An investment in GLD is subject to substantial risks, in particular risks associated with investing in the gold market. GLD is subject to market fluctuations influenced by large-scale gold sales, especially during economic crises, which can adversely impact gold prices and, in turn, the investment value of the Shares. Historical instances, such as the 2008 financial crisis, demonstrated this volatility, where substantial gold sales led to a marked decrease in its market price. Moreover, large disposals of gold by the official sector – encompassing central banks and other government entities – could result in a supply surplus, potentially diminishing gold’s market value. The valuation of the gold held by GLD is closely tied to the LBMA Gold Price PM. This benchmark is established through a bidding process by various market participants and any inaccuracies in its calculation or modifications to the benchmark process could significantly impact the Trust’s gold valuation and the investment value in Shares.
GLD faces significant custodial and safeguarding risks regarding its gold holdings. There is an inherent danger of these gold bars being lost, damaged, stolen, or becoming inaccessible due to factors such as natural disasters or terrorism. GLD does not insure its gold, and the insurance held by its custodian might not fully cover potential losses. The custodian’s liability is restricted to direct losses from negligence, fraud, or willful default, limited to the gold’s market value at the time of the incident, a constraint that also applies to any subcustodians. Additionally, legal and practical difficulties in foreign jurisdictions could complicate the enforcement of rights or claims. The custodian, not specifically regulated for gold bullion custody, relies on industry best practices and internal controls, which presents a security risk for GLD’s gold. Furthermore, gold in GLD’s unallocated accounts isn’t segregated from the custodian’s assets, thus in the event of the custodian’s insolvency, GLD would be an unsecured creditor, potentially leading to delays and extra costs in recovering allocated gold. These challenges in dealing with subcustodians and the potential complications in legal actions due to the lack of direct contractual arrangements and the intricacies of foreign legal systems highlight the significant custodial risks in investing in GLD Shares.

| Risk [Text Block] | rr_RiskTextBlock | Gold Performance Risk. Price movements in gold may fluctuate quickly and dramatically, have a historically low correlation with the returns of the stock and bond markets, and may not correlate to the price movements in other asset classes. The price of gold bullion can be significantly affected by international monetary and political developments such as currency devaluation or revaluation, central bank movements, economic and social conditions within a country, transactional or trade imbalances, or trade or currency restrictions between countries. Physical gold bullion has sales commission, storage, insurance and auditing expenses. Additional factors that impact the price of gold include, but are not limited to, overall market movements, changes in interest rates, changes in the global supply and demand for gold, the quantity of gold imports and exports, factors that impact gold production, such as drought, floods and weather conditions, technological advances in the processing and mining of gold and an increase in the hedging of precious metals, such as gold. Investments in gold generally may be speculative and subject to greater price volatility than investments in other types of assets. The price of metals, such as gold, is related to, among other things, worldwide metal prices and extraction and production costs. Worldwide metal prices may fluctuate substantially over short periods of time, and as a result, the Fund’s share price may be more volatile than other types of investments.

| Strategy [Heading] | rr_StrategyHeading | Principal Investment Strategies | |||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||
| Strategy Narrative [Text Block] | rr_StrategyNarrativeTextBlock | The Fund is an actively managed exchange-traded fund (“ETF”) that seeks current income while maintaining the opportunity for indirect exposure to the share price of iShares Silver Trust (“SLV” or the “Underlying ETP”), subject to a limit on potential gains related to increases in the price of SLV’s shares. While maintaining indirect exposure to the Underlying ETP, the Fund aims to generate additional income from its options investments when SLV’s share price rises in value, based on the specific put options it sold.
SLV is an exchange-traded product (“ETP”) that generally seeks to replicate the performance of the price of Silver bullion. SLV is not subject to the protections of the 1940 Act; however, the Fund and its shareholders are subject to the protections of the 1940 Act.
The Fund will not seek to invest directly in the ETP, however, due to the non-cash settlement nature of the fund’s options strategy, the Fund may be required from time to time to hold shares of the ETP. In such a case, the Fund will generally seek to sell such ETP holding the same day (to avoid adverse tax consequences to the Fund). As further described below, at least once a week, the Fund uses an at-the-money or in-the-money put selling strategy to provide income and exposure to the price of the Underlying ETP shares, subject to a limit on potential investment gains as a result of the nature of the options strategy it employs. The Fund’s options contracts provide current income from the premium it receives from the sale of such options contracts and a limit on the Fund’s indirect participation in gains, if any, of the increase in the price of the Underlying ETP’s shares. In addition, the Fund’s in-the-money put options will provide some upside appreciation, also known as “intrinsic value.” As discussed in greater detail below, the Fund will not directly or fully participate in gains experienced by the Underlying ETP. Please see “Additional Information about the Fund” below for a description of options terminology.
At least once a week, the Fund will sell put options that are priced either at-the-money or up to five percent in-the-money (i.e., higher than the current market price). If the Fund sells an option that’s priced above the current market price, the Fund may profit if the Underlying ETP’s share price increases above its current price, stays flat, or decreases slightly (i.e., the decrease to the Fund is less than the original extrinsic premium received). This opportunity exists until the option’s expiration date, which is typically one week or less (as of the date of this prospectus, options expire each Wednesday and Friday). In other words, the Fund’s potential for profit (or exposure) fluctuates. The Fund will initially use only European FLexible EXchange® (“FLEX”) options, but may also use options that are exercisable at any time (i.e. American style options contracts).
The Fund’s strategy focuses on having the ability to make monthly distributions through generating income throughout each week by regularly selling put options. Simultaneously, it aims to provide an “enhanced” yield compared to traditional option-based strategies by frequently selling short-term options, typically with a duration of less than a week. This method may result in higher income than with an approach of selling longer-term options over the same period, although there is no guarantee such an approach will result in higher income.
The Fund’s options contracts provide:
For more information, see the section “The Fund’s Use of Underlying ETP Option Contracts” below.
In addition to its options investments, the Fund will hold short-term U.S. Treasury securities for collateral for the options and to generate additional income for the Fund.
The Fund’s investment adviser is Tidal Investments LLC the “Adviser”) and the investment sub-adviser is ZEGA Financial, LLC (the “Sub-Adviser”).
Why invest in the Fund?
That is, although the Fund’s income gains related to gains in the Underlying ETP’s shares will be capped, the Fund’s portfolio is designed to generate income.
An Investment in the Fund is not an investment in SLV, nor in Silver bullion.
Additional information regarding SLV is set forth below.
The Fund’s Use of the Underlying ETP Option Contracts
Throughout each week, the Fund will sell at-the-money or in-the-money puts on the Underlying ETP. In particular, the Fund will sell puts with near-term expirations at a range of 0% to 5% “in-the-money” (i.e., where the strike price is above the current price of the Underlying ETP’s shares by between 0% and 5%). The Fund will receive premium income for each put sold. In addition, the strategy will provide the Fund with the opportunity to earn both time decay (described below) and, for in-the-money puts, a limited amount of upside appreciation up to the puts’ strike price (described below) plus the puts’ intrinsic value. The expiration dates at the time of purchase for the Fund’s sold puts will range from one day to a month (“Call Period”). The Fund’s participation in potential increases in the price of the Underlying ETP’s shares is based on the price of the Underlying ETP’s shares at the time the Fund sells a put option contract and the Underlying ETP’s share price at the time of the contract’s expiration.
For example, imagine the Underlying ETP’s shares are priced at $200, and a put option with a strike price of 205 is sold for $15. The difference between the strike price and the Underlying ETP’s share price is $5 (in-the-money amount). The remaining $10 (the $15 put price minus the $5 in-the-money amount) represents the put’s extrinsic value. In the case of this example:
As of the date of this prospectus, the available options are non-cash-settled. As a result, theoretically, the Fund would be obligated to receive shares of the Underlying ETP when the option was exercised. Consequently, there is a risk that the Fund may have to physically acquire the Underlying ETP shares at the strike price, which could result in the Fund holding the Underlying ETP’s share, and an asset that has declined in value. However, in such instances, the Fund will seek to avoid owning shares of the Underlying ETP by trading out of the puts prior to expiration or selling the delivered shares immediately upon receipt.
When selling put options, the Fund will generally be subject to different outcomes based on market movements and whether the options sold are at-the-money or in-the-money. Such outcomes may or may not be profitable to the Fund, depending on the circumstances, and there is no guarantee that any given situation will occur and be profitable to the Fund:
U.S. Treasuries
The Fund will hold short-term U.S. Treasury securities as collateral in connection with the Fund’s options strategy and to generate income.
Fund’s Monthly Distributions
The Fund will seek to provide monthly income in the form of cash distributions. The Fund will seek to generate such income in the following two ways:
Fund’s Return Profile vs. the Underlying ETP
For the reasons stated above, the Fund’s performance will differ from that of the Underlying ETP’s share prices. The performance differences will depend on, among other things, the price of the Underlying ETP’s shares, changes in the value of the Underlying ETP put options contracts the Fund has sold, and changes in the value of the U.S. Treasuries.
The Fund’s strategy is designed to have unleveraged, 100% downside notional exposure (as described below) to the Underlying ETP. Essentially, the assignment value of the put options that the Fund invests in will match the value as if the Fund had directly purchased the Underlying ETP’s shares.
Let’s consider a scenario where the Fund has assets totaling $10 million and the Underlying ETP is priced at 200. In this instance, the number of contracts would be 500. We calculate this by dividing the Fund’s value by the value of one contract. Here, $10,000,000 divided by $20,000 (obtained by multiplying the Underlying ETP’s share price of 200 by the standard multiplier of 100) gives us 500.
However, the Fund’s notional exposure, representing the theoretical exposure of its portfolio, will drift daily due to various factors such as market movements and changes in option prices. Notional value is calculated based on the quantity of assets underlying the options positions, multiplied by the strike price of the option. The Fund may reallocate its portfolio upon entering a new position at the option’s expiration. In this process, the Fund will allow its currently held options to expire, close them, or roll (closing out of existing options contracts to purchase new options contracts) them early. Subsequently, the Fund enters new put options positions when the existing ones have expired, been closed, or been rolled early. The Fund may allow the options to expire worthless in order to reduce execution costs and minimize trading drift.
Fund Portfolio
The Fund’s principal holdings are described below:
To fully collateralize the Fund’s options strategy, the market value of the cash and treasuries held by the Fund is expected to comprise at least 80% of the Fund’s net assets and the market value of the options is expected to be between 0% and 10% of the Fund’s net assets. The combination of these investments provides investment exposure to SLV such that the notional exposure is equal to 100% of the Fund’s total assets. The “notional exposure” is the return on or change in value of a particular dollar amount representing the underlying investment. The notional value and the market value both describe the value of a security. Notional value speaks to how much total value a security theoretically controls – for instance through options contracts. Market value, on the other hand, is the price of a security right now that can be bought and sold on an exchange or through a broker.
As a result of the Fund’s investment strategy, it may experience a high portfolio turnover rate.
The Fund is classified as “non-diversified” under the 1940 Act.
Under normal circumstances, the Fund will invest at least 80% of the value of its net assets, plus borrowings for investment purposes, in financial instruments and economic interests that provide exposure to the value of the Underlying ETP shares. For purposes of compliance with this investment policy, derivative contracts will be valued at their notional value.
There is no guarantee that the Fund’s investment strategy will be properly implemented, and an investor may lose some or all of its investment.

| Prospectus [Line Items] | rr_ProspectusLineItems | ||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||
| Risk [Text Block] | rr_RiskTextBlock | Derivatives Risk. Derivatives are financial instruments that derive value from the underlying reference asset or assets, such as stocks, bonds, or funds (including ETFs and ETPs), interest rates or indexes. The Fund’s investments in derivatives may pose risks in addition to, and greater than, those associated with directly investing in securities or other ordinary investments, including risk related to the market, imperfect correlation with underlying investments, higher price volatility, lack of availability, counterparty risk, liquidity, valuation and legal restrictions. The use of derivatives is a highly specialized activity that involves investment techniques and risks different from those associated with ordinary portfolio securities transactions. The use of derivatives may result in larger losses or smaller gains than directly investing in securities. When the Fund uses derivatives, there may be an imperfect correlation between the value of the Underlying ETP and the derivative, which may prevent the Fund from achieving its investment objectives. Because derivatives often require only a limited initial investment, the use of derivatives may expose the Fund to losses in excess of those amounts initially invested. In addition, the Fund’s investments in derivatives are subject to the following risks:

| Risk [Text Block] | rr_RiskTextBlock | Options Contracts. The use of options contracts involves investment strategies and risks different from those associated with ordinary portfolio securities transactions. The prices of options are volatile and are influenced by, among other things, actual and anticipated changes in the value of the underlying instrument, including the anticipated volatility, which are affected by fiscal and monetary policies and by national and international political, changes in the actual or implied volatility or the reference asset, the time remaining until the expiration of the option contract and economic events. For the Fund, in particular, the value of the options contracts in which it invests is substantially influenced by the value of the Underlying ETP. Selling put options exposes the Fund to the risk of potential loss if the market value of the Underlying ETP falls below the strike price before the option expires. The Fund may experience substantial downside from specific option positions and certain option positions held by the Fund may expire worthless. The options held by the Fund are exercisable at the strike price on their expiration date. As an option approaches its expiration date, its value typically increasingly moves with the value of the underlying instrument. However, prior to such date, the value of an option generally does not increase or decrease at the same rate at the underlying instrument. There may at times be an imperfect correlation between the movement in values options contracts and the underlying instrument, and there may at times not be a liquid secondary market for certain options contracts. The value of the options held by the Fund will be determined based on market quotations or other recognized pricing methods. Additionally, the Fund’s practice of rolling may cause the Fund to experience losses if the expiring contracts do not generate proceeds enough to cover the costs of entering into new options contracts. Further, if an option is exercised, the seller (writer) of a put option is obligated to purchase the underlying asset at the strike price, which can result in significant financial and regulatory obligations for the Fund if the market value of the asset has fallen substantially. Furthermore, when the Fund seeks to trade out of puts, especially near expiration, there is added risk that the Fund may be required to allocate resources unexpectedly to fulfill these obligations. This potential exposure to physical settlement can significantly impact the Fund’s liquidity and market exposure, particularly in volatile market conditions.

| Defiance Silver Enhanced Options Income ETF | Counterparty Risk [Member] | |||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||
| Prospectus [Line Items] | rr_ProspectusLineItems | ||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||
| Risk [Text Block] | rr_RiskTextBlock | Counterparty Risk. The Fund is subject to counterparty risk by virtue of its investments in options contracts. Transactions in some types of derivatives, including options, are required to be centrally cleared (“cleared derivatives”). In a transaction involving cleared derivatives, the Fund’s counterparty is a clearing house rather than a bank or broker. Since the Fund is not a member of clearing houses and only members of a clearing house (“clearing members”) can participate directly in the clearing house, the Fund will hold cleared derivatives through accounts at clearing members. In cleared derivatives positions, the Fund will make payments (including margin payments) to and receive payments from a clearing house through their accounts at clearing members. Customer funds held at a clearing organization in connection with any options 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 options 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 clearing house, there is a risk that the assets of the Fund might not be fully protected in the event of the clearing member’s bankruptcy, as the Fund would be limited to recovering only a pro rata share of all available funds segregated on behalf of the clearing member’s customers for the relevant account class. 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. 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.

| Defiance Silver Enhanced Options Income ETF | Price Participation Risk [Member] | |||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||
| Prospectus [Line Items] | rr_ProspectusLineItems | ||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||
| Risk [Text Block] | rr_RiskTextBlock | Price Participation Risk. The Fund employs an investment strategy that includes the sale of in-the-money put option contracts, which limits the degree to which the Fund will participate in increases in value experienced by the Underlying ETP over the Call Period (typically, one week, but may range from one day to a month). This means that if the Underlying ETP experiences an increase in value above the strike price of the sold put options during a Call Period, the Fund will likely not experience that increase to the same extent and may significantly underperform the Underlying ETP over the Call Period. Additionally, because the Fund is limited in the degree to which it will participate in increases in value experienced by the Underlying ETP over each Call Period, but has full exposure to any decreases in value experienced by the Underlying ETP over the Call Period, the NAV of the Fund may decrease over any given time period. The Fund’s NAV is dependent on the value of each options portfolio, which is based principally upon the performance of the Underlying ETP. The degree of participation in the Underlying ETP gains the Fund will experience will depend on prevailing market conditions, especially market volatility, at the time the Fund enters into the sold put option contracts and will vary from Call Period to Call Period. The value of the options contracts is affected by changes in the value and dividend rates of the Underlying ETP, changes in interest rates, changes in the actual or perceived volatility of the Underlying ETP and the remaining time to the options’ expiration, as well as trading conditions in the options market. As the price of the Underlying ETP changes and time moves towards the expiration of each Call Period, the value of the options contracts, and therefore the Fund’s NAV, will change. However, it is not expected for the Fund’s NAV to directly correlate on a day-to-day basis with the returns of the Underlying ETP. The amount of time remaining until the options contract’s expiration date affects the impact of the potential options contract income on the Fund’s NAV, which may not be in full effect until the expiration date of the Fund’s options contracts. Therefore, while changes in the price of the Underlying ETP will result in changes to the Fund’s NAV, the Fund generally anticipates that the rate of change in the Fund’s NAV will be different than that experienced by the Underlying ETP.

| Risk [Text Block] | rr_RiskTextBlock | Distribution Risk. As part of the Fund’s investment objective to provide current income, the Fund seeks to provide monthly income distributions. There is no assurance that the Fund will make a distribution in any given month. If the Fund does make distributions, the amounts of such distributions will likely vary greatly from one distribution to the next. Additionally, the monthly distributions, if any, may consist of returns of capital, which would decrease the Fund’s NAV and trading price over time. As a result, an investor may suffer significant losses to their investment.

| Prospectus [Line Items] | rr_ProspectusLineItems | ||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||
| Risk [Text Block] | rr_RiskTextBlock | NAV Erosion Risk Due to Distributions. When the Fund makes a distribution, the Fund’s NAV will typically drop by the amount of the distribution on the related ex-dividend date (i.e., the date by which you need to own a dividend-paying stock in order to receive the upcoming dividend payment). The repeated payment of distributions by the Fund, if any, may significantly erode the Fund’s NAV and trading price over time. As a result, an investor may suffer significant losses to their investment.

| Prospectus [Line Items] | rr_ProspectusLineItems | ||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||
| Risk [Text Block] | rr_RiskTextBlock | Put Writing Strategy Risk. The path dependency (i.e., the continued use) of the Fund’s put writing strategy will impact the extent that the Fund participates in the positive price returns of the Underlying ETP and, in turn, the Fund’s returns, both during the term of the sold put options and over longer time periods.
If, for example, the Fund were to sell 1% in-the-money put options having a one-week term, the Fund’s participation in the positive price returns of the Underlying ETP will be capped at 1% for that week. However, over a longer period (e.g., a four-week period), the Fund should not be expected to participate fully in the first 4% (i.e., 4 weeks x 1%) of the positive price returns of the Underlying ETP, or the Fund may even lose money, even if the Underlying ETP share price has appreciated by at least that much over such period, if during any particular week or weeks over that period the Underlying ETP had a return less than 1%. This example illustrates that both the Fund’s participation in the positive price returns of the Underlying ETP and its returns will depend not only on the price of the Underlying ETP but also on the path that the Underlying ETP takes over time.
Additionally, on a weekly basis, the Fund is generally fully exposed to the downward movements of the Underlying ETP, offset only by the premiums received from selling put contracts. The Fund does not seek to offer any downside protection, except for the fact that the premiums from the sold options may offset some or all of the Underlying ETP’s decline.

| Risk [Text Block] | rr_RiskTextBlock | Authorized Participants, Market Makers, and Liquidity Providers Concentration Risk. The Fund has a limited number of financial institutions that are authorized to purchase and redeem Shares directly from the Fund (known as “Authorized Participants” or “APs”). In addition, there may be a limited number of market makers and/or liquidity providers in the marketplace. To the extent either of the following events occur, Shares may trade at a material discount to NAV and possibly face delisting: (i) APs exit the business or otherwise become unable to process creation and/or redemption orders and no other APs step forward to perform these services; or (ii) market makers and/or liquidity providers exit the business or significantly reduce their business activities and no other entities step forward to perform their functions.

| Prospectus [Line Items] | rr_ProspectusLineItems | ||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||
| Risk [Text Block] | rr_RiskTextBlock | Cash Redemption Risk. The Fund’s investment strategy may require it to redeem Shares for cash or to otherwise include cash as part of its redemption proceeds. For example, the Fund may not be able to redeem in-kind certain securities held by the Fund (e.g., derivative instruments). In such a case, the Fund may be required to sell or unwind portfolio investments to obtain the cash needed to distribute redemption proceeds. This may cause the Fund to recognize a capital gain that it might not have recognized if it had made a redemption in-kind. As a result, the Fund may pay out higher annual capital gain distributions than if the in-kind redemption process was used. By paying out higher annual capital gain distributions, investors may be subjected to increased capital gains taxes. Additionally, there may be brokerage costs or taxable gains or losses that may be imposed on the Fund in connection with a cash redemption that may not have occurred if the Fund had made a redemption in-kind. These costs could decrease the value of the Fund to the extent they are not offset by a transaction fee payable by an AP.

| Risk [Text Block] | rr_RiskTextBlock | Trading. Although Shares are listed on a national securities exchange, such as The Nasdaq Stock Market, LLC (the “Exchange”), and may be traded on U.S. exchanges other than the Exchange, there can be no assurance that an active trading market for the Shares will develop or be maintained or that the Shares will trade with any volume, or at all, on any stock exchange. This risk may be greater for the Fund as it seeks to have exposure to a single underlying stock as opposed to a more diverse portfolio like a traditional pooled investment. In stressed market conditions, the liquidity of Shares may begin to mirror the liquidity of the Fund’s underlying portfolio holdings, which can be significantly less liquid than Shares. Shares trade on the Exchange at a market price that may be below, at or above the Fund’s NAV. Trading in Shares on the Exchange may be halted due to market conditions or for reasons that, in the view of the Exchange, make trading in Shares inadvisable. In addition, trading in Shares on the Exchange is subject to trading halts caused by extraordinary market volatility pursuant to the Exchange “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. In the event of an unscheduled market close for options contracts that reference a single stock, such as the Underlying ETP’s securities being halted or a market wide closure, settlement prices will be determined by the procedures of the listing exchange of the options contracts. As a result, the Fund could be adversely affected and be unable to implement its investment strategies in the event of an unscheduled closing.

| Risk [Text Block] | rr_RiskTextBlock | Liquidity Risk. Some securities held by the Fund, including options contracts, may be difficult to sell or be illiquid, particularly during times of market turmoil. This risk is greater for the Fund as it will hold options contracts on a single security, and not a broader range of options contracts. Markets for securities or financial instruments could be disrupted by a number of events, including, but not limited to, an economic crisis, natural disasters, epidemics/pandemics, new legislation or regulatory changes inside or outside the United States. Illiquid securities may be difficult to value, especially in changing or volatile markets. If the Fund is forced to sell an illiquid security at an unfavorable time or price, the Fund may be adversely impacted. Certain market conditions or restrictions, such as market rules related to short sales, may prevent the Fund from limiting losses, realizing gains or achieving a high correlation with the Underlying ETP. There is no assurance that a security that is deemed liquid when purchased will continue to be liquid. Market illiquidity may cause losses for the Fund.

| Risk [Text Block] | rr_RiskTextBlock | Market Events Risk. The Fund's investments are subject to changes in general economic conditions, general market fluctuations and the risks inherent in investment in securities and other financial instruments. Investment markets can be volatile and prices of investments can change substantially due to various factors including, but not limited to, economic growth or recession, changes in interest rates, inflation, changes in the actual or perceived creditworthiness of issuers, and general market liquidity. The Fund is subject to the risk that geopolitical events will disrupt securities and other financial markets and adversely affect global economies and markets. Local, regional or global events such as war, military conflicts, acts of terrorism, natural disasters, the spread of infectious illness or other public health issues, or other events could have a significant impact on the Fund and its investments. Continuing uncertainties regarding interest rates, rising inflation, political events, rising government debt in the U.S. and trade tensions also contribute to market volatility. Conflict, loss of life and disaster connected to ongoing armed conflict between Ukraine and Russia in Europe and between Israel and Hamas in the Middle East could have severe adverse effects on the related region, including significant adverse effects on the regional or global economies and the markets for certain securities. The U.S. and the European Union have imposed sanctions on certain Russian individuals and companies, including certain financial institutions, and have limited certain exports and imports to and from Russia. These conflicts have contributed to recent market volatility and may continue to do so.

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, Adviser, and Sub-Adviser seek to reduce these operational risks through controls and procedures, there is no way to completely protect against such risks.

| Risk [Text Block] | rr_RiskTextBlock | 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. To comply with the asset diversification test applicable to a RIC, the Fund will attempt to ensure that the value of options it holds is never 25% of the total value of Fund assets at the close of any quarter. If the Fund’s investments in options 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. In addition, distributions received by the Fund from the Underlying ETP may generate “bad income” that could prevent the Fund from meeting the “Income Requirement” of Subchapter M of the Code, which may cause the Fund to fail to qualify as a RIC.

Payment of principal and interest on U.S. Government obligations may be backed by the full faith and credit of the United States or may be backed solely by the issuing or guaranteeing agency or instrumentality itself. In the latter case, the investor must look principally to the agency or instrumentality issuing or guaranteeing the obligation for ultimate repayment, which agency or instrumentality may be privately owned. There can be no assurance that the U.S. Government would provide financial support to its agencies or instrumentalities (including government-sponsored enterprises) where it is not obligated to do so.

As a result, the Fund may be required to physically acquire Underlying ETP shares. In that case, it is likely that the value of these shares would have declined since the inception of the option contract. When the Fund physically acquires Underlying ETP shares, it will generally seek to sell them at market price promptly after receipt to avoid adverse tax consequences to the Fund.

| Prospectus [Line Items] | rr_ProspectusLineItems | ||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||
| Risk [Text Block] | rr_RiskTextBlock | SLV Trading Risk. An investment in SLV is subject to various risks, notably those linked to the dynamics and perception of the LBMA Silver Price. The LBMA, or London Bullion Market Association, plays a crucial role in setting the benchmark for silver prices. It is an international trade association representing the London market for gold and silver bullion, which has a major influence on the global bullion markets. The LBMA Silver Price, determined through an electronic auction managed by ICE Benchmark Administration, is central to the Trust’s valuation and operation. However, potential electronic failures or concerns about the LBMA Silver Price being susceptible to manipulation could lead to delays or inaccuracies in the auction price. This uncertainty could affect the Trust’s valuation of its silver holdings, the calculation of fees, and the pricing of silver sales. Moreover, a loss of confidence in the fairness or integrity of the LBMA Silver Price could change investor behavior, thereby impacting the overall silver market and the value of the shares.
SLV’s exclusive investment in silver heightens its volatility compared to more diversified portfolios. Silver prices, which SLV’s net asset value closely tracks, have historically experienced significant and unpredictable fluctuations. SLV is a speculative investment, suitable primarily for those who can absorb potential losses. The physical silver market’s supply and demand dynamics can further complicate this investment. For example, if the demand for silver exceeds the available supply that meets SLV’s standards, it could obstruct the issuance of new shares. Such a supply-demand mismatch may lead to increased volatility in the share price and a significant divergence from the net asset value. This scenario highlights the speculative nature of silver investments and emphasizes the need for investors to be cognizant of the potential for substantial losses or gains, influenced by market conditions and the inherent volatility of silver.

| Risk [Text Block] | rr_RiskTextBlock | Indirect Investments in SLV. SLV is not affiliated with the Trust, the Fund, the Adviser, the Sub-Adviser, or their respective affiliates and is not involved with the offering of the Fund in any way and has no obligation to consider your Shares in taking any corporate action that might affect the value of Shares. SLV is not a registered investment company subject to the 1940 Act. Accordingly, investors in SLV (including the Fund via its indirect investments) do not have the protections expressly provided by that statute, including: provisions preventing SLV insiders from managing SLV to their benefit and to the detriment of shareholders; provisions preventing SLV from issuing securities having inequitable or discriminatory provisions; provisions preventing management by irresponsible persons; provisions preventing the use of unsound or misleading methods of computing SLV earnings and asset value; provisions prohibiting suspension of redemptions (except under limited circumstances); provisions limiting fund leverage; provisions imposing a fiduciary duty on fund managers with respect to receipt of compensation for services; and provisions preventing changes in SLV’s character without the consent of shareholders. Investors in the Fund will not have voting rights and will not be able to influence management of SLV but will be exposed to the performance of SLV. Investors in the Fund will not have rights to receive dividends or other distributions or any other rights with respect to the Underlying ETP but will be subject to declines in the performance of the Underlying ETP. Although the Fund invests in SLV only indirectly, the Fund’s investments are subject to loss as a result of these risks.

| Risk [Text Block] | rr_RiskTextBlock | SLV Performance Risk. The iShares Silver Trust may fail to meet its publicly announced guidelines or other expectations about its business, which could cause the price of SLV to decline. The iShares Silver Trust provides guidance regarding its expected financial and business performance, such as projections regarding sales and production, as well as anticipated future revenues, gross margins, profitability and cash flows. Correctly identifying key factors affecting business conditions and predicting future events is inherently an uncertain process, and the guidance the iShares Silver Trust provides may not ultimately be accurate and has in the past been inaccurate in certain respects, such as the timing of new product manufacturing ramps. The guidance is based on certain assumptions such as those relating to global and local economic conditions, anticipated production and sales volumes (which generally are not linear throughout a given period), average sales prices, supplier and commodity costs, and planned cost reductions. If iShares Silver Trust’s guidance is not accurate or varies from actual results due to its inability to meet the assumptions or the impact on its financial performance that could occur as a result of various risks and uncertainties, the market value of common stock issued by iShares Silver Trust could decline significantly.
Following an investment in the iShares Silver Trust, several factors may have the effect of causing a decline in the prices of silver and a corresponding decline in the price of the shares. Among them: (i) A change in economic conditions, such as a recession, can adversely affect the price of silver. Silver is used in a wide range of industrial applications, and an economic downturn could have a negative impact on its demand and, consequently, its price and the price of the shares. (ii) A significant change in the attitude of speculators and investors towards silver. Should the speculative community take a negative view towards silver, a decline in world silver prices could occur, negatively impacting the price of the shares. (iii) A significant increase in silver price hedging activity by silver producers. Traditionally, silver producers have not hedged to the same extent as other producers of precious metals (gold, for example) do. Should there be an increase in the level of hedge activity of silver producing companies, it could cause a decline in world silver prices, adversely affecting the price of the shares.

| Strategy [Heading] | rr_StrategyHeading | Principal Investment Strategies | |||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||
| Strategy Narrative [Text Block] | rr_StrategyNarrativeTextBlock | The Fund is an actively managed exchange-traded fund (“ETF”) that seeks current income while maintaining the opportunity for indirect exposure to the share price of United States Oil Fund, LP (“USO” or the “Underlying ETP”), subject to a limit on potential gains related to increases in the price of USO’s shares. While maintaining indirect exposure to the Underlying ETP, the Fund aims to generate additional income from its options investments when USO’s share price rises in value, based on the specific put options it sold.
USO is an exchange-traded product (“ETP”) that generally seeks to replicate the performance of the price of light, sweet crude oil. USO is not subject to the protections of the 1940 Act; however, the Fund and its shareholders are subject to the protections of the 1940 Act.
The Fund will not seek to invest directly in the ETP, however, due to the non-cash settlement nature of the fund’s options strategy, the Fund may be required from time to time to hold shares of the ETP. In such a case, the Fund will generally seek to sell such ETP holding the same day (to avoid adverse tax consequences to the Fund). As, further described below, at least once a week, the Fund uses an at-the-money or in-the-money put selling strategy to provide income and exposure to the price of the Underlying ETP shares, subject to a limit on potential investment gains as a result of the nature of the options strategy it employs. The Fund’s options contracts provide current income from the premium it receives from the sale of such options contracts and a limit on the Fund’s indirect participation in gains, if any, of the increase in the price of the Underlying ETP’s shares. In addition, the Fund’s in-the-money put options will provide some upside appreciation, also known as “intrinsic value.” As discussed in greater detail below, the Fund will not directly or fully participate in gains experienced by the Underlying ETP. Please see “Additional Information about the Fund” below for a description of options terminology.
At least once a week, the Fund will sell put options that are priced either at-the-money or up to five percent in-the-money (i.e., higher than the current market price). If the Fund sells an option that’s priced above the current market price, the Fund may profit if the Underlying ETP’s share price increases above its current price, stays flat, or decreases slightly (i.e., the decrease to the Fund is less than the original extrinsic premium received). This opportunity exists until the option’s expiration date, which is typically one week or less (as of the date of this prospectus, options expire each Wednesday and Friday). In other words, the Fund’s potential for profit (or exposure) fluctuates. The Fund will initially use only European FLexible EXchange® (“FLEX”) options, but may also use options that are exercisable at any time (i.e. American style options contracts).
The Fund’s strategy focuses on having the ability to make monthly distributions through generating income throughout each week by regularly selling put options. Simultaneously, it aims to provide an “enhanced” yield compared to traditional option-based strategies by frequently selling short-term options, typically with a duration of less than a week. This method may result in higher income than with an approach of selling longer-term options over the same period, although there is no guarantee such an approach will result in higher income.
The Fund’s options contracts provide:
For more information, see the section “The Fund’s Use of Underlying ETP Option Contracts” below.
In addition to its options investments, the Fund will hold short-term U.S. Treasury securities for collateral for the options and to generate additional income for the Fund.
The Fund’s investment adviser is Tidal Investments LLC (the “Adviser”) and the investment sub-adviser is ZEGA Financial, LLC (the “Sub-Adviser”).
Why invest in the Fund?
That is, although the Fund’s income gains related to gains in the Underlying ETP’s shares will be capped, the Fund’s portfolio is designed to generate income.
An Investment in the Fund is not an investment in USO, nor in oil.
Additional information regarding USO is set forth below.
The Fund’s Use of the Underlying ETP Option Contracts
Throughout each week, the Fund will sell at-the-money or in-the-money puts on the Underlying ETP. In particular, the Fund will sell puts with near-term expirations at a range of 0% to 5% “in-the-money” (i.e., where the strike price is above the current price of the Underlying ETP’s shares by between 0% and 5%). The Fund will receive premium income for each put sold. In addition, the strategy will provide the Fund with the opportunity to earn both time decay (described below) and, for in-the-money puts, a limited amount of upside appreciation up to the puts’ strike price (described below) plus the puts’ intrinsic value. The expiration dates at the time of purchase for the Fund’s sold puts will range from one day to a month (“Call Period”). The Fund’s participation in potential increases in the price of the Underlying ETP’s shares is based on the price of the Underlying ETP’s shares at the time the Fund sells a put option contract and the Underlying ETP’s share price at the time of the contract’s expiration.
For example, imagine the Underlying ETP’s shares are priced at $200, and a put option with a strike price of 205 is sold for $15. The difference between the strike price and the Underlying ETP’s share price is $5 (in-the-money amount). The remaining $10 (the $15 put price minus the $5 in-the-money amount) represents the put’s extrinsic value. In the case of this example:
As of the date of this prospectus, the available options are non-cash-settled. As a result, theoretically, the Fund would be obligated to receive shares of the Underlying ETP when the option was exercised. Consequently, there is a risk that the Fund may have to physically acquire the Underlying ETP shares at the strike price, which could result in the Fund holding the Underlying ETP’s share, and an asset that has declined in value. However, in such instances, the Fund will seek to avoid owning shares of the Underlying ETP by trading out of the puts prior to expiration or selling the delivered shares immediately upon receipt.
When selling put options, the Fund will generally be subject to different outcomes based on market movements and whether the options sold are at-the-money or in-the-money. Such outcomes may or may not be profitable to the Fund, depending on the circumstances, and there is no guarantee that any given situation will occur and be profitable to the Fund:
U.S. Treasuries
The Fund will hold short-term U.S. Treasury securities as collateral in connection with the Fund’s options strategy and to generate income.
Fund’s Monthly Distributions
The Fund will seek to provide monthly income in the form of cash distributions. The Fund will seek to generate such income in the following two ways:
Fund’s Return Profile vs. the Underlying ETP
For the reasons stated above, the Fund’s performance will differ from that of the Underlying ETP’s share prices. The performance differences will depend on, among other things, the price of the Underlying ETP’s shares, changes in the value of the Underlying ETP put options contracts the Fund has sold, and changes in the value of the U.S. Treasuries.
The Fund’s strategy is designed to have unleveraged, 100% downside notional exposure (as described below) to the Underlying ETP. Essentially, the assignment value of the put options that the Fund invests in will match the value as if the Fund had directly purchased the Underlying ETP’s shares.
Let’s consider a scenario where the Fund has assets totaling $10 million and the Underlying ETP is priced at 200. In this instance, the number of contracts would be 500. We calculate this by dividing the Fund’s value by the value of one contract. Here, $10,000,000 divided by $20,000 (obtained by multiplying the Underlying ETP’s share price of 200 by the standard multiplier of 100) gives us 500.
However, the Fund’s notional exposure, representing the theoretical exposure of its portfolio, will drift daily due to various factors such as market movements and changes in option prices. Notional value is calculated based on the quantity of assets underlying the options positions, multiplied by the strike price of the option. The Fund may reallocate its portfolio upon entering a new position at the option’s expiration. In this process, the Fund will allow its currently held options to expire, close them, or roll (closing out of existing options contracts to purchase new options contracts) them early. Subsequently, the Fund enters new put options positions when the existing ones have expired, been closed, or been rolled early. The Fund may allow the options to expire worthless in order to reduce execution costs and minimize trading drift.
Fund Portfolio
The Fund’s principal holdings are described below:
To fully collateralize the Fund’s options strategy, the market value of the cash and treasuries held by the Fund is expected to comprise at least 80% of the Fund’s net assets and the market value of the options is expected to be between 0% and 10% of the Fund’s net assets. The combination of these investments provides investment exposure to USO such that the notional exposure is equal to 100% of the Fund’s total assets. The “notional exposure” is the return on or change in value of a particular dollar amount representing the underlying investment. The notional value and the market value both describe the value of a security. Notional value speaks to how much total value a security theoretically controls – for instance through options contracts. Market value, on the other hand, is the price of a security right now that can be bought and sold on an exchange or through a broker.
As a result of the Fund’s investment strategy, it may experience a high portfolio turnover rate.
The Fund is classified as “non-diversified” under the 1940 Act.
Under normal circumstances, the Fund will invest at least 80% of the value of its net assets, plus borrowings for investment purposes, in financial instruments and economic interests that provide exposure to the value of the Underlying ETP shares. For purposes of compliance with this investment policy, derivative contracts will be valued at their notional value.
There is no guarantee that the Fund’s investment strategy will be properly implemented, and an investor may lose some or all of its investment.
USO
United States Oil Fund, LP’s (“USO”) investment objective is for the daily changes in percentage terms of its per share net asset value (“NAV”) to reflect the daily changes in percentage terms of the spot price of light, sweet crude oil delivered to Cushing, Oklahoma, as measured by the daily changes in the price of a specified short-term futures contract on light, sweet crude oil called the “Benchmark Oil Futures Contract,” plus interest earned on USO’s collateral holdings, less USO’s expenses. USO seeks to achieve its investment objective by investing so that the average daily percentage change in USO’s NAV for any period of 30 successive valuation days will be within plus/minus ten percent (10%) of the average daily percentage change in the price of the Benchmark Oil Futures Contract over the same period. USO is an exchange traded fund organized as a limited partnership that issues shares that trade on the NYSE Arca stock exchange.
Investors can access information about USO, including its prospectus and the most recent shareholder reports, online through the SEC’s website, using SEC Registration Nos. 333-272617 and 001-32834.

| Risk [Text Block] | rr_RiskTextBlock | Derivatives Risk. Derivatives are financial instruments that derive value from the underlying reference asset or assets, such as stocks, bonds, or funds (including ETFs and ETPs), interest rates or indexes. The Fund’s investments in derivatives may pose risks in addition to, and greater than, those associated with directly investing in securities or other ordinary investments, including risk related to the market, imperfect correlation with underlying investments, higher price volatility, lack of availability, counterparty risk, liquidity, valuation and legal restrictions. The use of derivatives is a highly specialized activity that involves investment techniques and risks different from those associated with ordinary portfolio securities transactions. The use of derivatives may result in larger losses or smaller gains than directly investing in securities. When the Fund uses derivatives, there may be an imperfect correlation between the value of the Underlying ETP and the derivative, which may prevent the Fund from achieving its investment objectives. Because derivatives often require only a limited initial investment, the use of derivatives may expose the Fund to losses in excess of those amounts initially invested. In addition, the Fund’s investments in derivatives are subject to the following risks:

| Prospectus [Line Items] | rr_ProspectusLineItems | ||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||
| Risk [Text Block] | rr_RiskTextBlock | Options Contracts. The use of options contracts involves investment strategies and risks different from those associated with ordinary portfolio securities transactions. The prices of options are volatile and are influenced by, among other things, actual and anticipated changes in the value of the underlying instrument, including the anticipated volatility, which are affected by fiscal and monetary policies and by national and international political, changes in the actual or implied volatility or the reference asset, the time remaining until the expiration of the option contract and economic events. For the Fund, in particular, the value of the options contracts in which it invests is substantially influenced by the value of the Underlying ETP. Selling put options exposes the Fund to the risk of potential loss if the market value of the Underlying ETP falls below the strike price before the option expires. The Fund may experience substantial downside from specific option positions and certain option positions held by the Fund may expire worthless. The options held by the Fund are exercisable at the strike price on their expiration date. As an option approaches its expiration date, its value typically increasingly moves with the value of the underlying instrument. However, prior to such date, the value of an option generally does not increase or decrease at the same rate at the underlying instrument. There may at times be an imperfect correlation between the movement in values options contracts and the underlying instrument, and there may at times not be a liquid secondary market for certain options contracts. The value of the options held by the Fund will be determined based on market quotations or other recognized pricing methods. Additionally, the Fund’s practice of rolling may cause the Fund to experience losses if the expiring contracts do not generate proceeds enough to cover the costs of entering into new options contracts. Further, if an option is exercised, the seller (writer) of a put option is obligated to purchase the underlying asset at the strike price, which can result in significant financial and regulatory obligations for the Fund if the market value of the asset has fallen substantially. Furthermore, when the Fund seeks to trade out of puts, especially near expiration, there is an added risk that the Fund may be required to allocate resources unexpectedly to fulfill these obligations. This potential exposure to physical settlement can significantly impact the Fund’s liquidity and market exposure, particularly in volatile market conditions.

| Prospectus [Line Items] | rr_ProspectusLineItems | ||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||
| Risk [Text Block] | rr_RiskTextBlock | Counterparty Risk. The Fund is subject to counterparty risk by virtue of its investments in options contracts. Transactions in some types of derivatives, including options, are required to be centrally cleared (“cleared derivatives”). In a transaction involving cleared derivatives, the Fund’s counterparty is a clearing house rather than a bank or broker. Since the Fund is not a member of clearing houses and only members of a clearing house (“clearing members”) can participate directly in the clearing house, the Fund will hold cleared derivatives through accounts at clearing members. In cleared derivatives positions, the Fund will make payments (including margin payments) to and receive payments from a clearing house through their accounts at clearing members. Customer funds held at a clearing organization in connection with any options 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 options 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 clearing house, there is a risk that the assets of the Fund might not be fully protected in the event of the clearing member’s bankruptcy, as the Fund would be limited to recovering only a pro rata share of all available funds segregated on behalf of the clearing member’s customers for the relevant account class. 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. 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.

| Prospectus [Line Items] | rr_ProspectusLineItems | ||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||
| Risk [Text Block] | rr_RiskTextBlock | Price Participation Risk. The Fund employs an investment strategy that includes the sale of in-the-money put option contracts, which limits the degree to which the Fund will participate in increases in value experienced by the Underlying ETP over the Call Period (typically, one week, but may range from one day to a month). This means that if the Underlying ETP experiences an increase in value above the strike price of the sold put options during a Call Period, the Fund will likely not experience that increase to the same extent and may significantly underperform the Underlying ETP over the Call Period. Additionally, because the Fund is limited in the degree to which it will participate in increases in value experienced by the Underlying ETP over each Call Period, but has full exposure to any decreases in value experienced by the Underlying ETP over the Call Period, the NAV of the Fund may decrease over any given time period. The Fund’s NAV is dependent on the value of each options portfolio, which is based principally upon the performance of the Underlying ETP. The degree of participation in the Underlying ETP gains the Fund will experience will depend on prevailing market conditions, especially market volatility, at the time the Fund enters into the sold put option contracts and will vary from Call Period to Call Period. The value of the options contracts is affected by changes in the value and dividend rates of the Underlying ETP, changes in interest rates, changes in the actual or perceived volatility of the Underlying ETP and the remaining time to the options’ expiration, as well as trading conditions in the options market. As the price of the Underlying ETP changes and time moves towards the expiration of each Call Period, the value of the options contracts, and therefore the Fund’s NAV, will change. However, it is not expected for the Fund’s NAV to directly correlate on a day-to-day basis with the returns of the Underlying ETP. The amount of time remaining until the options contract’s expiration date affects the impact of the potential options contract income on the Fund’s NAV, which may not be in full effect until the expiration date of the Fund’s options contracts. Therefore, while changes in the price of the Underlying ETP will result in changes to the Fund’s NAV, the Fund generally anticipates that the rate of change in the Fund’s NAV will be different than that experienced by the Underlying ETP.

There is no assurance that the Fund will make a distribution in any given month. If the Fund does make distributions, the amounts of such distributions will likely vary greatly from one distribution to the next. Additionally, the monthly distributions, if any, may consist of returns of capital, which would decrease the Fund’s NAV and trading price over time. As a result, an investor may suffer significant losses to their investment.

| Prospectus [Line Items] | rr_ProspectusLineItems | ||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||
| Risk [Text Block] | rr_RiskTextBlock | NAV Erosion Risk Due to Distributions. When the Fund makes a distribution, the Fund’s NAV will typically drop by the amount of the distribution on the related ex-dividend date (i.e., the date by which you need to own a dividend-paying stock in order to receive the upcoming dividend payment). The repeated payment of distributions by the Fund, if any, may significantly erode the Fund’s NAV and trading price over time. As a result, an investor may suffer significant losses to their investment.

| Prospectus [Line Items] | rr_ProspectusLineItems | ||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||
| Risk [Text Block] | rr_RiskTextBlock | Put Writing Strategy Risk. The path dependency (i.e., the continued use) of the Fund’s put writing strategy will impact the extent that the Fund participates in the positive price returns of the Underlying ETP and, in turn, the Fund’s returns, both during the term of the sold put options and over longer time periods.
If, for example, the Fund were to sell 1% in-the-money put options having a one-week term, the Fund’s participation in the positive price returns of the Underlying ETP will be capped at 1% for that week. However, over a longer period (e.g., a four-week period), the Fund should not be expected to participate fully in the first 4% (i.e., 4 weeks x 1%) of the positive price returns of the Underlying ETP, or the Fund may even lose money, even if the Underlying ETP share price has appreciated by at least that much over such period, if during any particular week or weeks over that period the Underlying ETP had a return less than 1%. This example illustrates that both the Fund’s participation in the positive price returns of the Underlying ETP and its returns will depend not only on the price of the Underlying ETP but also on the path that the Underlying ETP takes over time.
Additionally, on a weekly basis, the Fund is generally fully exposed to the downward movements of the Underlying ETP, offset only by the premiums received from selling put contracts. The Fund does not seek to offer any downside protection, except for the fact that the premiums from the sold options may offset some or all of the Underlying ETP’s decline.

| Risk [Text Block] | rr_RiskTextBlock | Authorized Participants, Market Makers, and Liquidity Providers Concentration Risk. The Fund has a limited number of financial institutions that are authorized to purchase and redeem Shares directly from the Fund (known as “Authorized Participants” or “APs”). In addition, there may be a limited number of market makers and/or liquidity providers in the marketplace. To the extent either of the following events occur, Shares may trade at a material discount to NAV and possibly face delisting: (i) APs exit the business or otherwise become unable to process creation and/or redemption orders and no other APs step forward to perform these services; or (ii) market makers and/or liquidity providers exit the business or significantly reduce their business activities and no other entities step forward to perform their functions.

| Risk [Text Block] | rr_RiskTextBlock | Cash Redemption Risk. The Fund’s investment strategy may require it to redeem Shares for cash or to otherwise include cash as part of its redemption proceeds. For example, the Fund may not be able to redeem in-kind certain securities held by the Fund (e.g., derivative instruments). In such a case, the Fund may be required to sell or unwind portfolio investments to obtain the cash needed to distribute redemption proceeds. This may cause the Fund to recognize a capital gain that it might not have recognized if it had made a redemption in-kind. As a result, the Fund may pay out higher annual capital gain distributions than if the in-kind redemption process was used. By paying out higher annual capital gain distributions, investors may be subjected to increased capital gains taxes. Additionally, there may be brokerage costs or taxable gains or losses that may be imposed on the Fund in connection with a cash redemption that may not have occurred if the Fund had made a redemption in-kind. These costs could decrease the value of the Fund to the extent they are not offset by a transaction fee payable by an AP.

| Risk [Text Block] | rr_RiskTextBlock | Trading. Although Shares are listed on a national securities exchange, such as The Nasdaq Stock Market, LLC (the “Exchange”), and may be traded on U.S. exchanges other than the Exchange, there can be no assurance that an active trading market for the Shares will develop or be maintained or that the Shares will trade with any volume, or at all, on any stock exchange. This risk may be greater for the Fund as it seeks to have exposure to a single underlying stock as opposed to a more diverse portfolio like a traditional pooled investment. In stressed market conditions, the liquidity of Shares may begin to mirror the liquidity of the Fund’s underlying portfolio holdings, which can be significantly less liquid than Shares. Shares trade on the Exchange at a market price that may be below, at or above the Fund’s NAV. Trading in Shares on the Exchange may be halted due to market conditions or for reasons that, in the view of the Exchange, make trading in Shares inadvisable. In addition, trading in Shares on the Exchange is subject to trading halts caused by extraordinary market volatility pursuant to the Exchange “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. In the event of an unscheduled market close for options contracts that reference a single stock, such as the Underlying ETP’s securities being halted or a market wide closure, settlement prices will be determined by the procedures of the listing exchange of the options contracts. As a result, the Fund could be adversely affected and be unable to implement its investment strategies in the event of an unscheduled closing.

| Risk [Text Block] | rr_RiskTextBlock | Liquidity Risk. Some securities held by the Fund, including options contracts, may be difficult to sell or be illiquid, particularly during times of market turmoil. This risk is greater for the Fund as it will hold options contracts on a single security, and not a broader range of options contracts. Markets for securities or financial instruments could be disrupted by a number of events, including, but not limited to, an economic crisis, natural disasters, epidemics/pandemics, new legislation or regulatory changes inside or outside the United States. Illiquid securities may be difficult to value, especially in changing or volatile markets. If the Fund is forced to sell an illiquid security at an unfavorable time or price, the Fund may be adversely impacted. Certain market conditions or restrictions, such as market rules related to short sales, may prevent the Fund from limiting losses, realizing gains or achieving a high correlation with the Underlying ETP. There is no assurance that a security that is deemed liquid when purchased will continue to be liquid. Market illiquidity may cause losses for the Fund.

The Fund's investments are subject to changes in general economic conditions, general market fluctuations and the risks inherent in investment in securities and other financial instruments. Investment markets can be volatile and prices of investments can change substantially due to various factors including, but not limited to, economic growth or recession, changes in interest rates, inflation, changes in the actual or perceived creditworthiness of issuers, and general market liquidity. The Fund is subject to the risk that geopolitical events will disrupt securities and other financial markets and adversely affect global economies and markets. Local, regional or global events such as war, military conflicts, acts of terrorism, natural disasters, the spread of infectious illness or other public health issues, or other events could have a significant impact on the Fund and its investments. Continuing uncertainties regarding interest rates, rising inflation, political events, rising government debt in the U.S. and trade tensions also contribute to market volatility. Conflict, loss of life and disaster connected to ongoing armed conflict between Ukraine and Russia in Europe and between Israel and Hamas in the Middle East could have severe adverse effects on the related region, including significant adverse effects on the regional or global economies and the markets for certain securities. The U.S. and the European Union have imposed sanctions on certain Russian individuals and companies, including certain financial institutions, and have limited certain exports and imports to and from Russia. These conflicts have contributed to recent market volatility and may continue to do so.

| Risk [Text Block] | rr_RiskTextBlock | 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. To comply with the asset diversification test applicable to a RIC, the Fund will attempt to ensure that the value of options it holds is never 25% of the total value of Fund assets at the close of any quarter. If the Fund’s investments in options 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.

| Risk [Text Block] | rr_RiskTextBlock | USO Risk. The Fund invests in options contracts that are based on the value of USO. This subjects the Fund to certain of the same risks as if it owned shares of USO, even though it does not. By virtue of the Fund’s investments in options contracts that are based on the value of USO, the Fund may also be subject to the following risks:
Investments in USO are subject to unique risks, primarily stemming from the volatile nature of the oil market and the regulatory frameworks governing futures markets. The accountability levels, position limits, and daily price fluctuation limits set by NYMEX and ICE Futures, while intended to regulate trading activities, can lead to a significant tracking error for USO. These regulatory measures limit USO’s ability to fully invest in the Benchmark Oil Futures Contract and other oil futures contracts, thus potentially causing substantial divergence between the movements of USO’s share prices and the actual prices of these futures contracts. The oil market’s inherent volatility is further compounded by these trading constraints. Accountability levels serve as thresholds for increased exchange scrutiny, and position limits establish fixed ceilings on the number of futures contracts that can be held. The Commodity Futures Trading Commission’s (CFTC) Position Limits Rule, which includes the Benchmark Oil Futures Contract, imposes additional federal position limits. USO’s trading activities, not qualifying for exemptions from these limits, face further challenges in navigating the unpredictable oil market, impacting its investment strategy and ability to achieve its objectives.
USO’s investment strategy is heavily influenced by the dynamic and often unpredictable oil market, alongside its commitment to invest substantially in Oil Futures Contracts and Other Oil-Related Investments. When faced with regulatory limits such as accountability levels and position limits, USO may have to adjust its strategy, seeking alternatives like other exchanges or different investment vehicles, which could introduce additional market risks. Exceeding accountability levels may necessitate a reduction in holdings, potentially creating a tracking error between USO’s share prices and the Benchmark Oil Futures Contract price. Furthermore, USO’s Futures Commission Merchants (FCMs) have historically imposed their own limits on USO’s holdings, which restricts its ability to respond effectively to oil market movements. These FCM-imposed constraints, alongside the fluctuating nature of the oil market and regulatory limitations, underscore the significant risks associated with investing in USO, affecting its capacity to meet investment objectives in a highly volatile and regulated market environment.
USO is not a registered investment company subject to the 1940 Act. Accordingly, investors in USO (including the Fund via its indirect investments) do not have the protections expressly provided by that statute, including: provisions preventing USO insiders from managing USO to their benefit and to the detriment of shareholders; provisions preventing USO from issuing securities having inequitable or discriminatory provisions; provisions preventing management by irresponsible persons; provisions preventing the use of unsound or misleading methods of computing USO earnings and asset value; provisions prohibiting suspension of redemptions (except under limited circumstances); provisions limiting fund leverage; provisions imposing a fiduciary duty on fund managers with respect to receipt of compensation for services; and provisions preventing changes in USO’s character without the consent of shareholders. Although the Fund invests in USO only indirectly, the Fund’s investments are subject to loss as a result of these risks.

| Strategy [Heading] | rr_StrategyHeading | Principal Investment Strategies | |||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||
| Strategy Narrative [Text Block] | rr_StrategyNarrativeTextBlock | The Fund is an actively managed exchange-traded fund (“ETF”) that seeks current income while maintaining the opportunity for indirect exposure to the share price of iShares 20+ Year Treasury Bond ETF (“TLT” or the “Underlying ETP”), subject to a limit on potential gains related to increases in the value of TLT’s shares. While maintaining indirect exposure to the Underlying ETP, the Fund aims to generate additional income from its options investments when TLT’s share price rises in value, based on the specific put options it sold.
TLT is an ETF that generally seeks to track the performance of U.S. Treasury obligations with a maturity of twenty years or more.
The Fund will not seek to invest directly in the ETP, however, due to the non-cash settlement nature of the fund’s options strategy, the Fund may be required from time to time to hold shares of the ETP. In such a case, the Fund will generally seek to sell such ETP holding the same day (to avoid adverse tax consequences to the Fund). As, as further described below, at least once a week, the Fund uses an at-the-money or in-the-money put selling strategy to provide income and exposure to the price of the Underlying ETP shares, subject to a limit on potential investment gains as a result of the nature of the options strategy it employs. The Fund’s options contracts provide current income from the premium it receives from the sale of such options contracts and a limit on the Fund’s indirect participation in gains, if any, of the increase in the price of the Underlying ETP’s shares. In addition, the Fund’s in-the-money put options will provide some upside appreciation, also known as “intrinsic value.” As discussed in greater detail below, the Fund will not directly or fully participate in gains experienced by the Underlying ETP. Please see “Additional Information about the Fund” below for a description of options terminology.
At least once a week, the Fund will sell put options that are priced either at-the-money or up to five percent in-the-money (i.e., higher than the current market price). If the Fund sells an option that’s priced above the current market price, the Fund may profit if the Underlying ETP’s share price increases above its current price, stays flat, or decreases slightly (i.e., the decrease to the Fund is less than the original extrinsic premium received). This opportunity exists until the option’s expiration date, which is typically one week or less (as of the date of this prospectus, options expire each Wednesday and Friday). In other words, the Fund’s potential for profit (or exposure) fluctuates. The Fund will initially use only European FLexible EXchange® (“FLEX”) options, but may also use options that are exercisable at any time (i.e. American style options contracts).
The Fund’s strategy focuses on having the ability to make monthly distributions through generating income throughout each week by regularly selling put options. Simultaneously, it aims to provide an “enhanced” yield compared to traditional option-based strategies by frequently selling short-term options, typically with a duration of less than a week. This method may result in higher income than with an approach of selling longer-term options over the same period, although there is no guarantee such an approach will result in higher income.
The Fund’s options contracts provide:
For more information, see the section “The Fund’s Use of Underlying ETP Option Contracts” below.
In addition to its options investments, the Fund will hold short-term U.S. Treasury securities for collateral for the options and to generate additional income for the Fund.
The Fund’s investment adviser is Tidal Investments LLC (the “Adviser”) and the investment sub-adviser is ZEGA Financial, LLC (the “Sub-Adviser”).
Why invest in the Fund?
● The Fund seeks to generate monthly income through its options strategy, which is not dependent on the price appreciation of the Underlying ETP’s shares.
● The Fund seeks to indirectly participate in a portion of the potential gains experienced by increases in the Underlying ETP’s shares (via income from its options holdings).
That is, although the Fund’s income gains related to gains in the Underlying ETP’s shares will be capped, the Fund’s portfolio is designed to generate income.
An Investment in the Fund is not an investment in TLT, nor primarily in Treasury Bonds.
Additional information regarding TLT is set forth below.
The Fund’s Use of the Underlying ETP Option Contracts
Throughout each week, the Fund will sell at-the-money or in-the-money puts on the Underlying ETP. In particular, the Fund will sell puts with near-term expirations at a range of 0% to 5% “in-the-money” (i.e., where the strike price is above the current price of the Underlying ETP’s shares by between 0% and 5%). The Fund will receive premium income for each put sold. In addition, the strategy will provide the Fund with the opportunity to earn both time decay (described below) and, for in-the-money puts, a limited amount of upside appreciation up to the puts’ strike price (described below) plus the puts’ intrinsic value. The expiration dates at the time of purchase for the Fund’s sold puts will range from one day to a month (“Call Period”). The Fund’s participation in potential increases in the price of the Underlying ETP’s shares is based on the price of the Underlying ETP’s shares at the time the Fund sells a put option contract and the Underlying ETP’s share price at the time of the contract’s expiration.
For example, imagine the Underlying ETP’s shares are priced at $200, and a put option with a strike price of 205 is sold for $15. The difference between the strike price and the Underlying ETP’s share price is $5 (in-the-money amount). The remaining $10 (the $15 put price minus the $5 in-the-money amount) represents the put’s extrinsic value. In the case of this example:
As of the date of this prospectus, the available options are non-cash-settled. As a result, theoretically, the Fund would be obligated to receive shares of the Underlying ETP when the option was exercised. Consequently, there is a risk that the Fund may have to physically acquire the Underlying ETP shares at the strike price, which could result in the Fund holding the Underlying ETP’s share, and an asset that has declined in value. However, in such instances, the Fund will seek to avoid owning shares of the Underlying ETP by trading out of the puts prior to expiration or selling the delivered shares immediately upon receipt.
When selling put options, the Fund will generally be subject to different outcomes based on market movements and whether the options sold are at-the-money or in-the-money. Such outcomes may or may not be profitable to the Fund, depending on the circumstances, and there is no guarantee that any given situation will occur and be profitable to the Fund:
U.S. Treasuries
The Fund will hold short-term U.S. Treasury securities as collateral in connection with the Fund’s options strategy and to generate income.
Fund’s Monthly Distributions
The Fund will seek to provide monthly income in the form of cash distributions. The Fund will seek to generate such income in the following two ways:
Fund’s Return Profile vs. the Underlying ETP
For the reasons stated above, the Fund’s performance will differ from that of the Underlying ETP’s share prices. The performance differences will depend on, among other things, the price of the Underlying ETP’s shares, changes in the value of the Underlying ETP put options contracts the Fund has sold, and changes in the value of the U.S. Treasuries.
The Fund’s strategy is designed to have unleveraged, 100% downside notional exposure (as described below) to the Underlying ETP. Essentially, the assignment value of the put options that the Fund invests in will match the value as if the Fund had directly purchased the Underlying ETP’s shares.
Let’s consider a scenario where the Fund has assets totaling $10 million and the Underlying ETP is priced at 200. In this instance, the number of contracts would be 500. We calculate this by dividing the Fund’s value by the value of one contract. Here, $10,000,000 divided by $20,000 (obtained by multiplying the Underlying ETP’s share price of 200 by the standard multiplier of 100) gives us 500.
However, the Fund’s notional exposure, representing the theoretical exposure of its portfolio, will drift daily due to various factors such as market movements and changes in option prices. Notional value is calculated based on the quantity of assets underlying the options positions, multiplied by the strike price of the option. The Fund may reallocate its portfolio upon entering a new position at the option’s expiration. In this process, the Fund will allow its currently held options to expire, close them, or roll (closing out of existing options contracts to purchase new options contracts) them early. Subsequently, the Fund enters new put options positions when the existing ones have expired, been closed, or been rolled early. The Fund may allow the options to expire worthless in order to reduce execution costs and minimize trading drift.
Fund Portfolio
The Fund’s principal holdings are described below:
To fully collateralize the Fund’s options strategy, the market value of the cash and treasuries held by the Fund is expected to comprise at least 80% of the Fund’s net assets and the market value of the options is expected to be between 0% and 10% of the Fund’s net assets. The combination of these investments provides investment exposure to TLT such that the notional exposure is equal to 100% of the Fund’s total assets. The “notional exposure” is the return on or change in value of a particular dollar amount representing the underlying investment. The notional value and the market value both describe the value of a security. Notional value speaks to how much total value a security theoretically controls – for instance through options contracts. Market value, on the other hand, is the price of a security right now that can be bought and sold on an exchange or through a broker.
As a result of the Fund’s investment strategy, it may experience a high portfolio turnover rate.
The Fund is classified as “non-diversified” under the 1940 Act.
Under normal circumstances, the Fund will invest at least 80% of the value of its net assets, plus borrowings for investment purposes, in financial instruments and economic interests that provide exposure to the value of the Underlying ETP shares. For purposes of compliance with this investment policy, derivative contracts will be valued at their notional value.
There is no guarantee that the Fund’s investment strategy will be properly implemented, and an investor may lose some or all of its investment.
TLT
iShares 20+ Year Treasury Bond ETF’s (“TLT”) investment objective is to seek to track the investment results of a benchmark index, which tracks the performance of U.S. Treasury obligations with a maturity of twenty years or more.

| Risk [Text Block] | rr_RiskTextBlock | Derivatives Risk. Derivatives are financial instruments that derive value from the underlying reference asset or assets, such as stocks, bonds, or funds (including ETFs and ETPs), interest rates or indexes. The Fund’s investments in derivatives may pose risks in addition to, and greater than, those associated with directly investing in securities or other ordinary investments, including risk related to the market, imperfect correlation with underlying investments, higher price volatility, lack of availability, counterparty risk, liquidity, valuation and legal restrictions. The use of derivatives is a highly specialized activity that involves investment techniques and risks different from those associated with ordinary portfolio securities transactions. The use of derivatives may result in larger losses or smaller gains than directly investing in securities. When the Fund uses derivatives, there may be an imperfect correlation between the value of the Underlying ETP and the derivative, which may prevent the Fund from achieving its investment objectives. Because derivatives often require only a limited initial investment, the use of derivatives may expose the Fund to losses in excess of those amounts initially invested. In addition, the Fund’s investments in derivatives are subject to the following risks:

| Risk [Text Block] | rr_RiskTextBlock | Options Contracts. The use of options contracts involves investment strategies and risks different from those associated with ordinary portfolio securities transactions. The prices of options are volatile and are influenced by, among other things, actual and anticipated changes in the value of the underlying instrument, including the anticipated volatility, which are affected by fiscal and monetary policies and by national and international political, changes in the actual or implied volatility or the reference asset, the time remaining until the expiration of the option contract and economic events. For the Fund, in particular, the value of the options contracts in which it invests is substantially influenced by the value of the Underlying ETP. Selling put options exposes the Fund to the risk of potential loss if the market value of the Underlying ETP falls below the strike price before the option expires. The Fund may experience substantial downside from specific option positions and certain option positions held by the Fund may expire worthless. The options held by the Fund are exercisable at the strike price on their expiration date. As an option approaches its expiration date, its value typically increasingly moves with the value of the underlying instrument. However, prior to such date, the value of an option generally does not increase or decrease at the same rate at the underlying instrument. There may at times be an imperfect correlation between the movement in values options contracts and the underlying instrument, and there may at times not be a liquid secondary market for certain options contracts. The value of the options held by the Fund will be determined based on market quotations or other recognized pricing methods. Additionally, the Fund’s practice of rolling may cause the Fund to experience losses if the expiring contracts do not generate proceeds enough to cover the costs of entering into new options contracts. Further, if an option is exercised, the seller (writer) of a put option is obligated to purchase the underlying asset at the strike price, which can result in significant financial and regulatory obligations for the Fund if the market value of the asset has fallen substantially. Furthermore, when the Fund seeks to trade out of puts, especially near expiration, there is an added risks that the Fund may be required to allocate resources unexpectedly to fulfill these obligations. This potential exposure to physical settlement can significantly impact the Fund’s liquidity and market exposure, particularly in volatile market conditions.

| Prospectus [Line Items] | rr_ProspectusLineItems | ||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||
| Risk [Text Block] | rr_RiskTextBlock | Counterparty Risk. The Fund is subject to counterparty risk by virtue of its investments in options contracts. Transactions in some types of derivatives, including options, are required to be centrally cleared (“cleared derivatives”). In a transaction involving cleared derivatives, the Fund’s counterparty is a clearing house rather than a bank or broker. Since the Fund is not a member of clearing houses and only members of a clearing house (“clearing members”) can participate directly in the clearing house, the Fund will hold cleared derivatives through accounts at clearing members. In cleared derivatives positions, the Fund will make payments (including margin payments) to and receive payments from a clearing house through their accounts at clearing members. Customer funds held at a clearing organization in connection with any options 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 options 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 clearing house, there is a risk that the assets of the Fund might not be fully protected in the event of the clearing member’s bankruptcy, as the Fund would be limited to recovering only a pro rata share of all available funds segregated on behalf of the clearing member’s customers for the relevant account class. 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. 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.

| Defiance Treasury Enhanced Options Income ETF | Price Participation Risk [Member] | |||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||
| Prospectus [Line Items] | rr_ProspectusLineItems | ||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||
| Risk [Text Block] | rr_RiskTextBlock | Price Participation Risk. The Fund employs an investment strategy that includes the sale of in-the-money put option contracts, which limits the degree to which the Fund will participate in increases in value experienced by the Underlying ETP over the Call Period (typically, one week, but may range from one day to a month). This means that if the Underlying ETP experiences an increase in value above the strike price of the sold put options during a Call Period, the Fund will likely not experience that increase to the same extent and may significantly underperform the Underlying ETP over the Call Period. Additionally, because the Fund is limited in the degree to which it will participate in increases in value experienced by the Underlying ETP over each Call Period, but has full exposure to any decreases in value experienced by the Underlying ETP over the Call Period, the NAV of the Fund may decrease over any given time period. The Fund’s NAV is dependent on the value of each options portfolio, which is based principally upon the performance of the Underlying ETP. The degree of participation in the Underlying ETP gains the Fund will experience will depend on prevailing market conditions, especially market volatility, at the time the Fund enters into the sold put option contracts and will vary from Call Period to Call Period. The value of the options contracts is affected by changes in the value and dividend rates of the Underlying ETP, changes in interest rates, changes in the actual or perceived volatility of the Underlying ETP and the remaining time to the options’ expiration, as well as trading conditions in the options market. As the price of the Underlying ETP changes and time moves towards the expiration of each Call Period, the value of the options contracts, and therefore the Fund’s NAV, will change. However, it is not expected for the Fund’s NAV to directly correlate on a day-to-day basis with the returns of the Underlying ETP. The amount of time remaining until the options contract’s expiration date affects the impact of the potential options contract income on the Fund’s NAV, which may not be in full effect until the expiration date of the Fund’s options contracts. Therefore, while changes in the price of the Underlying ETP will result in changes to the Fund’s NAV, the Fund generally anticipates that the rate of change in the Fund’s NAV will be different than that experienced by the Underlying ETP.

| Risk [Text Block] | rr_RiskTextBlock | Distribution Risk. As part of the Fund’s investment objective to provide current income, the Fund seeks to provide monthly income distributions. There is no assurance that the Fund will make a distribution in any given month. If the Fund does make distributions, the amounts of such distributions will likely vary greatly from one distribution to the next. Additionally, the monthly distributions, if any, may consist of returns of capital, which would decrease the Fund’s NAV and trading price over time. As a result, an investor may suffer significant losses to their investment.

| Risk [Text Block] | rr_RiskTextBlock | NAV Erosion Risk Due to Distributions. When the Fund makes a distribution, the Fund’s NAV will typically drop by the amount of the distribution on the related ex-dividend date (i.e., the date by which you need to own a dividend-paying stock in order to receive the upcoming dividend payment). The repeated payment of distributions by the Fund, if any, may significantly erode the Fund’s NAV and trading price over time. As a result, an investor may suffer significant losses to their investment.

| Prospectus [Line Items] | rr_ProspectusLineItems | ||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||
| Risk [Text Block] | rr_RiskTextBlock | Put Writing Strategy Risk. The path dependency (i.e., the continued use) of the Fund’s put writing strategy will impact the extent that the Fund participates in the positive price returns of the Underlying ETP and, in turn, the Fund’s returns, both during the term of the sold put options and over longer time periods.
If, for example, the Fund were to sell 1% in-the-money put options having a one-week term, the Fund’s participation in the positive price returns of the Underlying ETP will be capped at 1% for that week. However, over a longer period (e.g., a four-week period), the Fund should not be expected to participate fully in the first 4% (i.e., 4 weeks x 1%) of the positive price returns of the Underlying ETP, or the Fund may even lose money, even if the Underlying ETP share price has appreciated by at least that much over such period, if during any particular week or weeks over that period the Underlying ETP had a return less than 1%. This example illustrates that both the Fund’s participation in the positive price returns of the Underlying ETP and its returns will depend not only on the price of the Underlying ETP but also on the path that the Underlying ETP takes over time.
Additionally, on a weekly basis, the Fund is generally fully exposed to the downward movements of the Underlying ETP, offset only by the premiums received from selling put contracts. The Fund does not seek to offer any downside protection, except for the fact that the premiums from the sold options may offset some or all of the Underlying ETP’s decline.

The Fund has a limited number of financial institutions that are authorized to purchase and redeem Shares directly from the Fund (known as “Authorized Participants” or “APs”). In addition, there may be a limited number of market makers and/or liquidity providers in the marketplace. To the extent either of the following events occur, Shares may trade at a material discount to NAV and possibly face delisting: (i) APs exit the business or otherwise become unable to process creation and/or redemption orders and no other APs step forward to perform these services; or (ii) market makers and/or liquidity providers exit the business or significantly reduce their business activities and no other entities step forward to perform their functions.

| Prospectus [Line Items] | rr_ProspectusLineItems | ||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||
| Risk [Text Block] | rr_RiskTextBlock | Cash Redemption Risk. The Fund’s investment strategy may require it to redeem Shares for cash or to otherwise include cash as part of its redemption proceeds. For example, the Fund may not be able to redeem in-kind certain securities held by the Fund (e.g., derivative instruments). In such a case, the Fund may be required to sell or unwind portfolio investments to obtain the cash needed to distribute redemption proceeds. This may cause the Fund to recognize a capital gain that it might not have recognized if it had made a redemption in-kind. As a result, the Fund may pay out higher annual capital gain distributions than if the in-kind redemption process was used. By paying out higher annual capital gain distributions, investors may be subjected to increased capital gains taxes. Additionally, there may be brokerage costs or taxable gains or losses that may be imposed on the Fund in connection with a cash redemption that may not have occurred if the Fund had made a redemption in-kind. These costs could decrease the value of the Fund to the extent they are not offset by a transaction fee payable by an AP.

| Risk [Text Block] | rr_RiskTextBlock | Trading. Although Shares are listed on a national securities exchange, such as The Nasdaq Stock Market, LLC (the “Exchange”), and may be traded on U.S. exchanges other than the Exchange, there can be no assurance that an active trading market for the Shares will develop or be maintained or that the Shares will trade with any volume, or at all, on any stock exchange. This risk may be greater for the Fund as it seeks to have exposure to a single underlying stock as opposed to a more diverse portfolio like a traditional pooled investment. In stressed market conditions, the liquidity of Shares may begin to mirror the liquidity of the Fund’s underlying portfolio holdings, which can be significantly less liquid than Shares. Shares trade on the Exchange at a market price that may be below, at or above the Fund’s NAV. Trading in Shares on the Exchange may be halted due to market conditions or for reasons that, in the view of the Exchange, make trading in Shares inadvisable. In addition, trading in Shares on the Exchange is subject to trading halts caused by extraordinary market volatility pursuant to the Exchange “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. In the event of an unscheduled market close for options contracts that reference a single stock, such as the Underlying ETP’s securities being halted or a market wide closure, settlement prices will be determined by the procedures of the listing exchange of the options contracts. As a result, the Fund could be adversely affected and be unable to implement its investment strategies in the event of an unscheduled closing.

| Risk [Text Block] | rr_RiskTextBlock | Liquidity Risk. Some securities held by the Fund, including options contracts, may be difficult to sell or be illiquid, particularly during times of market turmoil. This risk is greater for the Fund as it will hold options contracts on a single security, and not a broader range of options contracts. Markets for securities or financial instruments could be disrupted by a number of events, including, but not limited to, an economic crisis, natural disasters, epidemics/pandemics, new legislation or regulatory changes inside or outside the United States. Illiquid securities may be difficult to value, especially in changing or volatile markets. If the Fund is forced to sell an illiquid security at an unfavorable time or price, the Fund may be adversely impacted. Certain market conditions or restrictions, such as market rules related to short sales, may prevent the Fund from limiting losses, realizing gains or achieving a high correlation with the Underlying ETP. There is no assurance that a security that is deemed liquid when purchased will continue to be liquid. Market illiquidity may cause losses for the Fund.

| Risk [Text Block] | rr_RiskTextBlock | Market Events Risk. The Fund’s investments are subject to changes in general economic conditions, general market fluctuations and the risks inherent in investment in securities and other financial instruments. Investment markets can be volatile and prices of investments can change substantially due to various factors including, but not limited to, economic growth or recession, changes in interest rates, inflation, changes in the actual or perceived creditworthiness of issuers, and general market liquidity. The Fund is subject to the risk that geopolitical events will disrupt securities and other financial markets and adversely affect global economies and markets. Local, regional or global events such as war, military conflicts, acts of terrorism, natural disasters, the spread of infectious illness or other public health issues, or other events could have a significant impact on the Fund and its investments. Continuing uncertainties regarding interest rates, rising inflation, political events, rising government debt in the U.S. and trade tensions also contribute to market volatility. Conflict, loss of life and disaster connected to ongoing armed conflict between Ukraine and Russia in Europe and between Israel and Hamas in the Middle East could have severe adverse effects on the related region, including significant adverse effects on the regional or global economies and the markets for certain securities. The U.S. and the European Union have imposed sanctions on certain Russian individuals and companies, including certain financial institutions, and have limited certain exports and imports to and from Russia. These conflicts have contributed to recent market volatility and may continue to do so.

| Prospectus [Line Items] | rr_ProspectusLineItems | ||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||
| Risk [Text Block] | rr_RiskTextBlock | Non-Diversification Risk. Because the Fund is “non-diversified,” it may invest a greater percentage of its assets in the securities of a single issuer or a smaller number of issuers than if it was a diversified fund. As a result, a decline in the value of an investment in a single issuer or a smaller number of issuers could cause the Fund’s overall value to decline to a greater degree than if the Fund held a more diversified portfolio.

| Prospectus [Line Items] | rr_ProspectusLineItems | ||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||
| Risk [Text Block] | rr_RiskTextBlock | 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, Adviser, and Sub-Adviser seek to reduce these operational risks through controls and procedures, there is no way to completely protect against such risks.

| Risk [Text Block] | rr_RiskTextBlock | 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.

| Defiance Treasury Enhanced Options Income ETF | U.S. Government and U.S. Agency Obligations Risk [Member] | |||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||
| Prospectus [Line Items] | rr_ProspectusLineItems | ||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||
| Risk [Text Block] | rr_RiskTextBlock | U.S. Government and U.S. Agency Obligations Risk. The Fund may invest in securities issued by the U.S. government or its agencies or instrumentalities. U.S. Government obligations include securities issued or guaranteed as to principal and interest by the U.S. Government, its agencies or instrumentalities, such as the U.S. Treasury. Payment of principal and interest on U.S. Government obligations may be backed by the full faith and credit of the United States or may be backed solely by the issuing or guaranteeing agency or instrumentality itself. In the latter case, the investor must look principally to the agency or instrumentality issuing or guaranteeing the obligation for ultimate repayment, which agency or instrumentality may be privately owned. There can be no assurance that the U.S. Government would provide financial support to its agencies or instrumentalities (including government-sponsored enterprises) where it is not obligated to do so.

| Prospectus [Line Items] | rr_ProspectusLineItems | ||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||
| Risk [Text Block] | rr_RiskTextBlock | New Fund Risk. The Fund is a recently organized management investment company with no operating history. As a result, prospective investors do not have a track record or history on which to base their investment decisions.

| Prospectus [Line Items] | rr_ProspectusLineItems | ||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||
| Risk [Text Block] | rr_RiskTextBlock | Non-Cash Settled Options Risk. As of the date of this prospectus, the available options are non-cash settled. As a result, the Fund may be required to physically acquire Underlying ETP shares. In that case, it is likely that the value of these shares would have declined since the inception of the option contract. When the Fund physically acquires Underlying ETP shares, it will generally seek to sell them at market price promptly after receipt to avoid adverse tax consequences to the Fund. If the Underlying ETP’s shares decline further during the time the Fund holds them, it would negatively impact the Fund’s performance.

| Prospectus [Line Items] | rr_ProspectusLineItems | ||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||
| Risk [Text Block] | rr_RiskTextBlock | Single Issuer Risk. Issuer-specific attributes may cause an investment in the Fund to be more volatile than a traditional pooled investment vehicle which diversifies risk or the market generally. The value of the Fund, which focuses on an individual security (TLT), may be more volatile than a traditional pooled investment or the market as a whole and may perform differently from the value of a traditional pooled investment or the market as a whole.

| Defiance Treasury Enhanced Options Income ETF | TLT Risk [Member] | |||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||
| Prospectus [Line Items] | rr_ProspectusLineItems | ||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||
| Risk [Text Block] | rr_RiskTextBlock | TLT Risk. The Fund invests in options contracts that are based on the value of TLT. This subjects the Fund to certain of the same risks as if it owned shares of TLT, even though it does not. By virtue of the Fund’s investments in options contracts that are based on the value of TLT, the Fund may also be subject to the following risks:
Investments in TLT primarily involve U.S. Government and U.S. Agency obligations risk as described below. In addition, TLT is subject to interest rate risk, where the value of its Treasury securities can decline with rising interest rates. In periods of very low or negative interest rates, TLT may struggle to maintain positive returns or pay dividends to shareholders. The unpredictability of changing interest rates, including those falling below zero, can lead to heightened market volatility and detract from TLT’s performance. Additionally, in a low-interest-rate environment, TLT may experience very low or even negative yields, leading to losses under certain conditions and over specific time periods.
TLT is also subject to operational risk arising from human error, processing errors, and system failures. In addition, TLT is subject to management risk, including the possibility that the chosen investment strategy may not yield expected results. Lastly, the performance of U.S. Treasury obligations may be negatively impacted by global events, such as economic downturns, political unrest, or public health crises.
