Portfolio Turnover [Heading] rr_PortfolioTurnoverHeading Portfolio Turnover
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 of the Fund are held in a taxable account. These costs, which are not reflected in annual fund operating expenses or in the Example above, affect the Fund’s performance. For the fiscal period January 23, 2024 (commencement of operations) through November 30, 2024, the Fund’s portfolio turnover rate was 13% of the average value of its portfolio.

Although your actual costs may be higher or lower, based on these assumptions your cost would be:

Strategy [Heading] rr_StrategyHeading Principal Investment Strategies
Strategy Narrative [Text Block] rr_StrategyNarrativeTextBlock

The Fund normally invests in securities comprising the Index. The Index is designed to track the performance of companies that are involved in the nuclear fuel and energy industry (the “Nuclear Industry”), particularly in the areas of (i) advanced reactors; (ii) utilities; (iii) construction and services; and/or (iv) fuel (“Nuclear Companies”). Under normal circumstances, the Fund invests at least 80% of its net assets (plus the amount of any borrowings for investment purposes) in securities of Nuclear Companies.

 

The universe of eligible index components consists of exchange-listed equity securities of Nuclear Companies including common stock, depositary receipts, and master limited partnerships (“MLPs”). Such companies are identified by Range Fund Holdings, LLC (the “Index Provider”) through the use of a proprietary selection methodology that includes a review of industry publications, sell side research, and fundamental research, as well as meetings with management. The companies are classified into one of the following categories:

 

● Pure Play - Companies that currently or may in the future derive greater than or equal to 50% of revenues from business activities associated with the Nuclear Industry.
● Pre-Revenue - Companies that have primary business operations in the business activities associated with the Nuclear Industry but do not currently generate revenues.
● Diversified - Companies that derive greater than 0% but less than 50% of revenues from the business activities associated with the Nuclear Industry.

 

Companies eligible for inclusion based on their exposure to the Nuclear Industry are those companies that have publicly disclosed through regulatory filings (e.g., Form 10-K, 10-Q, 20-F, and 8-K filings), quarterly earnings reports, company presentations or official earnings conference call transcripts either that they currently provide or intend to provide or operate services in, to, or in connection with the Nuclear Industry. Companies that have made such public announcements through regulatory filings or other official communications are included in the Index because such announcements are an indication of the significance of what the company has held out as its current or future activities. In any event, there can be no guarantee that a company’s activities in the Nuclear Industry will become significant for the company or that its economic fortunes will be tied to such activities in the future. In constructing the Index, Nuclear Companies are divided among four buckets (advanced reactor, utilities, construction and services, and fuel) and each bucket is capped as follows: 30% advanced reactor securities; 30% utilities securities; 35% construction and services securities; and 20% fuel securities. The components within each of these buckets are weighted according to market capitalization. A single security cap of 10% is applied for Pure Play securities and Pre-Revenue securities. Diversified securities are subject to a single security cap of 3%. Any single security that does not reach a 1% allocation is excluded. If a bucket or security cap is reached, excess weight is distributed proportionately among uncapped securities. No more than five securities in the Index have a weight over 4.75% and the aggregate weight of all components with a weight greater than 5% is capped at 49.5%.

 

To the extent the Index includes securities of MLPs, the aggregate exposure to such MLPs is capped at 25%. Special Purpose Acquisition Company (SPAC) targets are eligible for inclusion once they are trading on a public exchange as the target entity, provided they meet all other eligibility criteria. The Index consists of securities of issuers from around the world including emerging markets countries, but excludes issuers domiciled and/or listed on exchanges in China or Russia. There is no limitation on the amount of foreign or emerging market securities that may be included in the Index. As of March 3, 2025, a significant portion of the Index consisted of securities of United States issuers.

 

To be initially included in the Index, the market capitalization of a company must be at least $100 million, and to remain in the Index a company must maintain a minimum market capitalization of $50 million. As of March 3, 2025, the Index was comprised of 38 component securities.

 

The Index is reconstituted and rebalanced on a semi-annual basis at the end of March and September. Deletions from the Index may be made at any time due to changes in business, mergers, acquisitions, bankruptcies, suspensions, de-listings and spin-offs. New constituents will not be added to the Index in between rebalances. The Index is unmanaged and cannot be invested in directly.

  

The Fund employs a “passive management” investment strategy designed to track the performance of the Index. Exchange Traded Concepts, LLC (the “Adviser”) generally uses a replication methodology, meaning it invests in all of the securities comprising the Index in proportion to their respective weightings in the Index. However, the Adviser may utilize a sampling methodology under various circumstances, including when it may not be possible or practicable to purchase all of the securities in the Index. The Adviser expects that over time, if the Fund has sufficient assets, the correlation between the Fund’s performance, before fees and expenses, and that of the Index will be 95% or better. A figure of 100% would indicate perfect correlation.

 

The Fund may invest up to 20% of its assets in investments that are not included in the Index, but that the Adviser believes will help the Fund track the performance of the Index.

 

The Fund will concentrate its investments (i.e., invest more than 25% of its total assets) in a particular industry or group of industries to approximately the same extent that the Index concentrates in an industry or group of industries. As of March 3, 2025, the Index was concentrated in the Electric Utilities Industry. In addition, in replicating the Index, the Fund may from time to time invest a significant portion of its assets in the securities of companies in one or more sectors. As of March 3, 2025, a significant portion of the Index consisted of companies in the Industrial Sector and Utilities Sector.

 

The Fund is classified as a “non-diversified” investment company under the Investment Company Act of 1940 (the “1940 Act”) and, therefore, may invest a greater percentage of its assets in a particular issuer than a diversified fund.

 

The Index Provider developed the methodology for determining the securities to be included in the Index and is responsible for the ongoing maintenance of the Index, oversight of the implementation of the index methodology, and changes in classification of the securities in the Index (such as from Pre-Revenue to Pure Play, for example).

 

The Index is calculated and published by Indxx, LLC (the “Index Calculator”). The Index Calculator is responsible for implementing the semi-annual rebalance and reconstitution and monitoring and implementing any adjustments, additions and deletions to the Index based on the index methodology and certain corporate actions, such as initial public offerings, mergers, acquisitions, bankruptcies, suspensions, de-listings, tender offers and spin-offs. Neither the Index Provider nor the Index Calculator is affiliated with each other or with the Fund or the Adviser.

Range Nuclear Renaissance Index ETF | Risk Nondiversified Status [Member]  
Risk/Return: rr_RiskReturnAbstract  
Risk [Text Block] rr_RiskTextBlock The Fund is non-diversified under the 1940 Act, meaning that, as compared to a diversified fund, it can invest a greater percentage of its assets in securities issued by or representing a small number of issuers. As a result, the performance of these issuers can have a substantial impact on the Fund’s performance.
Range Nuclear Renaissance Index ETF | Common Stock Risk [Member]  
Risk/Return: rr_RiskReturnAbstract  
Risk [Text Block] rr_RiskTextBlock

Common Stock Risk. Common stock holds the lowest priority in the capital structure of a company, and therefore takes the largest share of the company’s risk and its accompanying volatility. The value of the common stock held by the Fund may fall due to general market and economic conditions, perceptions regarding the industries in which the issuers of securities held by the Fund participate, or facts relating to specific companies in which the Fund invests.

Range Nuclear Renaissance Index ETF | Currency Exchange Rate Risk [Member]  
Risk/Return: rr_RiskReturnAbstract  
Risk [Text Block] rr_RiskTextBlock

Currency Exchange Rate Risk. To the extent the Fund invests in securities denominated in non-U.S. currencies, changes in currency exchange rates and the relative value of non-U.S. currencies will affect the value of the Fund’s investment and the value of your shares. Because the Fund’s net asset value (“NAV”) is determined in U.S. dollars, the Fund’s NAV could decline if the currency of the non-U.S. market in which the Fund invests depreciates against the U.S. dollar, even if the value of the Fund’s holdings, measured in the foreign currency, increases. Currency exchange rates can be very volatile and can change quickly and unpredictably. As a result, the value of an investment in the Fund may change quickly and without warning and you may lose money.

Range Nuclear Renaissance Index ETF | Cybersecurity Risk [Member]  
Risk/Return: rr_RiskReturnAbstract  
Risk [Text Block] rr_RiskTextBlock

Cybersecurity Risk. The Fund is susceptible to operational risks through breaches in cybersecurity. A breach in cybersecurity refers to both intentional and unintentional events that may cause the Fund to lose proprietary information, suffer data corruption or lose operational capacity. Such events could cause the Fund to incur regulatory penalties, reputational damage, additional compliance costs associated with corrective measures and/or financial loss. Cybersecurity breaches may involve unauthorized access to the Fund’s digital information systems through “hacking” or malicious software coding but may also result from outside attacks such as denial-of-service attacks through efforts to make network services unavailable to intended users. In addition, cybersecurity breaches of the issuers of securities in which the Fund invests or the Fund’s third-party service providers, such as its administrator, transfer agent, custodian, or sub-adviser, as applicable, can also subject the Fund to many of the same risks associated with direct cybersecurity breaches. Although the Fund has established risk management systems designed to reduce the risks associated with cybersecurity, there is no guarantee that such efforts will succeed, especially because the Fund does not directly control the cybersecurity systems of issuers or third-party service providers.

Range Nuclear Renaissance Index ETF | Deferred Tax Liability Risk [Member]  
Risk/Return: rr_RiskReturnAbstract  
Risk [Text Block] rr_RiskTextBlock

Deferred Tax Liability Risk. Cash distributions from an MLP to the Fund that exceed the Fund’s allocable share of the MLP’s taxable income are considered return of capital that reduce the Fund’s adjusted tax basis in the Fund’s MLP equity securities. Such distributions are not ordinarily subject to tax at the time of distribution unless the distributions exceed the Fund’s adjusted tax basis in the Fund’s MLP equity securities. The reductions in the Fund’s adjusted tax basis in Fund’s interest in the MLP will increase the amount of gain (or decrease the amount of loss) recognized by the Fund on a subsequent sale of the MLP equity securities. The Fund will accrue deferred income taxes for any future tax liability associated with: (i) that portion of MLP distributions considered to be a tax-deferred return of capital; and (ii) capital appreciation of its investments. Upon the sale of an MLP security, the Fund may be liable for previously deferred taxes. The Fund’s accrued deferred tax liability will be reflected each day in the Fund’s net asset value (“NAV”). Increases in deferred tax liability will decrease NAV. Conversely, decreases in deferred liability will increase NAV. The Fund will rely to some extent on information provided by the MLPs, which is not necessarily timely, to estimate deferred tax liability for purposes of financial statement reporting and determining the NAV. From time to time, the Fund will modify the estimates or assumptions regarding the Fund’s deferred tax liability as new information becomes available. The Fund’s estimates regarding its deferred tax liability are made in good faith; however, the daily estimate of the Fund’s deferred tax liability used to calculate the Fund’s NAV could vary significantly from the Fund’s actual tax liability. The Fund will generally compute deferred income taxes based on the federal income tax rate applicable to corporations and an assumed rate attributable to state taxes.

Range Nuclear Renaissance Index ETF | Depositary Receipt Risk [Member]  
Risk/Return: rr_RiskReturnAbstract  
Risk [Text Block] rr_RiskTextBlock

Depositary Receipt Risk. Depositary receipts such as American Depositary Receipts (“ADRs”) and Global Depositary Receipts (“GDRs”) are subject to the risks associated with investing directly in foreign securities. In addition, investments in depositary receipts may be less liquid than the underlying shares in their primary trading market.

Range Nuclear Renaissance Index ETF | Early Close/Trading Halt Risk [Member]  
Risk/Return: rr_RiskReturnAbstract  
Risk [Text Block] rr_RiskTextBlock

Early Close/Trading Halt Risk. An exchange or market may close or issue trading halts on specific securities, or the ability to buy or sell certain securities or financial instruments may be restricted, which may result in the Fund being unable to buy or sell certain securities or financial instruments. In such circumstances, the Fund may be unable to rebalance its portfolio, may be unable to accurately price its investments and/or may incur substantial trading losses.

Range Nuclear Renaissance Index ETF | Emerging Markets Securities Risk [Member]  
Risk/Return: rr_RiskReturnAbstract  
Risk [Text Block] rr_RiskTextBlock

Emerging Markets Securities Risk. Emerging markets are subject to greater market volatility, lower trading volume, political and economic instability, uncertainty regarding the existence of trading markets and more governmental limitations on foreign investment than more developed markets. In addition, securities in emerging markets may be subject to greater price fluctuations than securities in more developed markets. Differences in regulatory, accounting, auditing, and financial reporting and recordkeeping standards could impede the Adviser’s ability to evaluate local companies and impact the Fund’s performance. Investments in securities of issuers in emerging markets may also be exposed to risks related to a lack of liquidity, greater potential for market manipulation, issuers’ limited reliable access to capital, and foreign investment structures. Additionally, the Fund may have limited rights and remedies available to it to pursue claims against issuers in emerging markets.

Range Nuclear Renaissance Index ETF | Foreign Securities Risk [Member]  
Risk/Return: rr_RiskReturnAbstract  
Risk [Text Block] rr_RiskTextBlock

Foreign Securities Risk. Investments in non-U.S. securities involve certain risks that may not be present with investments in U.S. securities. For example, investments in non-U.S. securities may be subject to risk of loss due to foreign currency fluctuations or to expropriation, nationalization or adverse political or economic developments. Foreign securities may have relatively low market liquidity and decreased publicly available information about issuers. Investments in non-U.S. securities also may be subject to withholding or other taxes and may be subject to additional trading, settlement, custodial, and operational risks. Non-U.S. issuers may also be subject to inconsistent and potentially less stringent accounting, auditing, financial reporting and investor protection standards than U.S. issuers. These and other factors can make investments in the Fund more volatile and potentially less liquid than other types of investments. In addition, where all or a portion of the Fund’s portfolio holdings trade in markets that are closed when the Fund’s market is open, there may be valuation differences that could lead to differences between the Fund’s market price and the value of the Fund’s portfolio holdings.

Range Nuclear Renaissance Index ETF | Geographic Investment Risk [Member]  
Risk/Return: rr_RiskReturnAbstract  
Risk [Text Block] rr_RiskTextBlock

Geographic Investment Risk. To the extent the Fund invests a significant portion of its assets in the securities of companies of a single country or region, it is more likely to be impacted by events or conditions affecting that country or region. As of March 3, 2025, a significant portion of the Index consisted of securities of United States issuers.

 

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

Range Nuclear Renaissance Index ETF | Index Tracking Risk [Member]  
Risk/Return: rr_RiskReturnAbstract  
Risk [Text Block] rr_RiskTextBlock

Index Tracking Risk. The Fund’s return may not match or achieve a high degree of correlation with the return of the Index. To the extent the Fund utilizes a sampling approach, it may experience tracking error to a greater extent than if the Fund sought to replicate the Index.

Range Nuclear Renaissance Index ETF | Industry Concentration Risk [Member]  
Risk/Return: rr_RiskReturnAbstract  
Risk [Text Block] rr_RiskTextBlock

Industry Concentration Risk. Because the Fund’s assets will be concentrated in an industry or group of industries to the extent the Index concentrates in a particular industry or group of industries, the Fund is subject to loss due to adverse occurrences that may affect that industry or group of industries. The list below is not a comprehensive list of the industries to which the Fund may have exposure over time and should not be relied on as such. As of March 3, 2025, the Index was concentrated in the Electric Utilities Industry.

 

Electric Utilities Industry Risk. The Electric Utilities Industry includes companies that produce or distribute electricity, including both nuclear and non-nuclear. The prices of securities in the Electric Utilities Industry may fluctuate significantly due to supply and demand, governmental regulation and environmental issues, economic conditions generally affecting electric and utilities companies, competitive pressures due to deregulation in the electric and utilities industries, increased sensitivity to the cost of energy production; and environmental factors such as conservation of natural resources or pollution control. Legislative or regulatory changes and increased government supervision also may affect companies in the Electric Utilities Industry. The Electric Utilities Industry is a separate industry within the Utilities Sector.

Range Nuclear Renaissance Index ETF | Issuer-Specific Risk [Member]  
Risk/Return: rr_RiskReturnAbstract  
Risk [Text Block] rr_RiskTextBlock

Issuer-Specific Risk. Fund performance depends on the performance of the issuers to which the Fund has exposure. Issuer-specific events, including changes in the financial condition of an issuer, can have a negative impact on the value of the Fund.

Range Nuclear Renaissance Index ETF | Large-Capitalization Risk [Member]  
Risk/Return: rr_RiskReturnAbstract  
Risk [Text Block] rr_RiskTextBlock

Large-Capitalization Risk. Returns on investments in securities of large companies could trail the returns on investments in securities of smaller and mid-sized companies or the market as a whole. The securities of large-capitalization companies may also be relatively mature compared to smaller companies and therefore subject to slower growth during times of economic expansion. Large-capitalization companies may also be unable to respond quickly to new competitive challenges, such as changes in technology and consumer tastes.

Range Nuclear Renaissance Index ETF | Limited Authorized Participants, Market Makers and Liquidity Providers Risk [Member]  
Risk/Return: rr_RiskReturnAbstract  
Risk [Text Block] rr_RiskTextBlock

Limited Authorized Participants, Market Makers and Liquidity Providers Risk. Because the Fund is an ETF, only a limited number of institutional investors (known as “Authorized Participants”) are authorized to purchase and redeem shares directly from the Fund. 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 occurs, the risk of which is higher during periods of market stress, shares of the Fund may trade at a material discount to NAV, possibly face delisting, and may experience wide bid-ask spreads: (i) Authorized Participants exit the business or otherwise become unable to process creation and/or redemption orders and no other Authorized Participants 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.

Range Nuclear Renaissance Index ETF | Market Risk [Member]  
Risk/Return: rr_RiskReturnAbstract  
Risk [Text Block] rr_RiskTextBlock

Market Risk. The market price of an investment could decline, sometimes rapidly or unpredictably, due to general market conditions that are not specifically related to a particular company, such as real or perceived adverse economic or political conditions throughout the world, changes in the general outlook for corporate earnings, changes in interest or currency rates, or adverse investor sentiment generally. The market value of an investment also may decline because of factors that affect a particular industry or industries such as labor shortages, increased production costs, and competitive conditions. Local, regional, or global events such as war, acts of terrorism, the spread of infectious illness or other public health issues, recessions, or other events could have a significant impact on the market generally and on specific investments. For example, in recent years, the COVID-19 pandemic, the large expansion of government deficits and debt as a result of government actions to mitigate the effects of the pandemic, Russia’s invasion of Ukraine, and the rise of inflation have resulted in extreme volatility in the global economy and in global financial markets. Economies and financial markets throughout the world are becoming increasingly interconnected. As a result, whether or not the Fund invests in securities of issuers located in or with significant exposure to countries experiencing economic and financial difficulties, the value and liquidity of the Fund’s investments may be negatively affected.

Range Nuclear Renaissance Index ETF | Master Limited Partnership Risk [Member]  
Risk/Return: rr_RiskReturnAbstract  
Risk [Text Block] rr_RiskTextBlock

Master Limited Partnership Risk. MLPs are subject to certain risks inherent in the structure of MLPs, including tax risks, limited control and voting rights and potential conflicts of interest. MLPs that concentrate in a particular industry or a particular geographic region are subject to risks associated with such industry or region. Securities issued by MLPs may experience limited trading volumes and, thus, may be relatively illiquid or volatile at times. As partnerships, MLPs may be subject to less regulation (and less protection for investors) under state laws than corporations. In addition, MLPs may be subject to state taxation in certain jurisdictions, which may reduce the amount of income an MLP pays to its investors.

Range Nuclear Renaissance Index ETF | Methodology Risk [Member]  
Risk/Return: rr_RiskReturnAbstract  
Risk [Text Block] rr_RiskTextBlock

Methodology Risk. The Fund seeks to track the performance of stocks of companies selected using a methodology developed by the Index Provider. No assurance can be given that companies selected according to the methodology will outperform stocks of other companies. Moreover, there is no guarantee that the methodology will generate or produce the intended results.

Range Nuclear Renaissance Index ETF | Micro-Capitalization Risk [Member]  
Risk/Return: rr_RiskReturnAbstract  
Risk [Text Block] rr_RiskTextBlock

Micro-Capitalization Risk. The micro-capitalization companies in which the Fund may invest may be more vulnerable to adverse business or economic events than larger, more established companies, and may underperform other segments of the market or the equity market as a whole. Securities of micro-capitalization companies generally trade in lower volumes, are often more vulnerable to market volatility, and are subject to greater and more unpredictable price changes than larger capitalization stocks or the stock market as a whole.

Range Nuclear Renaissance Index ETF | MLP Tax Risk [Member]  
Risk/Return: rr_RiskReturnAbstract  
Risk [Text Block] rr_RiskTextBlock

MLP Tax Risk. The Fund’s ability to meet its investment objective relies in part upon the level of taxable income it receives from the MLPs in which it invests, a factor over which the Fund has no control. The benefit the Fund derives from its investment in MLPs is largely dependent on their being treated as partnerships for U.S. federal income tax purposes. Partnerships do not pay U.S. federal income tax at the partnership level. Rather, each partner is allocated a share of the partnership’s income, gains, losses, deductions and expenses. A change in current tax law or a change in the underlying business mix of a given MLP could result in an MLP being treated as a corporation for U.S. federal income tax purposes, which would result in the MLP being required to pay U.S. federal income tax (as well as state and local income taxes) on its taxable income at the applicable corporate tax rate. This would have the effect of reducing the amount of cash available for distribution by an MLP and could result in a significant reduction in the value of the Fund’s investment. The classification of an MLP as a corporation for U. S. federal income tax purposes would have the effect of reducing the amount of cash available for distribution by the MLP and causing any such distributions received by the Fund to be taxed as dividend income to the extent of the MLP’s current or accumulated earnings and profits. To the extent a distribution received by the Fund from an MLP is treated as a return of capital, the Fund’s adjusted tax basis in the interests of the MLP may be reduced, which will result in an increase in the amount of income or gain (or decrease in the amount of loss) that will be recognized by the Fund for tax purposes upon the sale of any such interests or upon subsequent distributions in respect of such interests. Furthermore, any return of capital distribution received from an MLP may require the Fund to restate the character of its distributions and amend any shareholder tax reporting previously issued. See “Deferred Tax Liability Risk.”

Range Nuclear Renaissance Index ETF | Non-Diversification Risk [Member]  
Risk/Return: rr_RiskReturnAbstract  
Risk [Text Block] rr_RiskTextBlock

Non-Diversification Risk. The Fund is non-diversified under the 1940 Act, meaning that, as compared to a diversified fund, it can invest a greater percentage of its assets in securities issued by or representing a small number of issuers. As a result, the performance of these issuers can have a substantial impact on the Fund’s performance.

Range Nuclear Renaissance Index ETF | Operational Risk [Member]  
Risk/Return: rr_RiskReturnAbstract  
Risk [Text Block] rr_RiskTextBlock

Operational Risk. The Fund and its service providers may experience disruptions that arise from human error, processing and communications errors, counterparty or third-party errors, technology or systems failures, any of which may have an adverse impact on the Fund.

Range Nuclear Renaissance Index ETF | Passive Investment Risk [Member]  
Risk/Return: rr_RiskReturnAbstract  
Risk [Text Block] rr_RiskTextBlock

Passive Investment Risk. The Fund is not actively managed and, therefore, the Fund would not sell a security due to current or projected underperformance of the security, industry, or sector unless that security is removed from the Index or selling the security is otherwise required upon a rebalancing of the Index.

Range Nuclear Renaissance Index ETF | Risk of Investing in Nuclear Companies [Member]  
Risk/Return: rr_RiskReturnAbstract  
Risk [Text Block] rr_RiskTextBlock

Risk of Investing in Nuclear Companies. The Fund will be sensitive to, and its performance will depend to a greater extent on, the overall condition of nuclear companies. Nuclear companies may face considerable risk as a result of, among other risks, incidents and accidents, breaches of security, ill-intentioned acts of terrorism, air crashes, natural disasters (such as floods or earthquakes), equipment malfunctions or mishandling in storage, handling, transportation, treatment or conditioning of substances and nuclear materials. Such events could have serious consequences, especially in case of radioactive contamination and irradiation of the environment, for the general population, as well as a material, negative impact on the Fund’s portfolio companies and thus the Fund’s financial situation. In addition, nuclear companies are subject to competitive risk associated with the prices of other energy sources, such as natural gas and oil. Consumers of nuclear energy may have the ability to switch between nuclear energy and other energy sources and, as a result, during periods when competing energy sources are less expensive, the revenues of nuclear energy companies may decline with a corresponding impact on earnings.

Range Nuclear Renaissance Index ETF | Sector Focus Risk [Member]  
Risk/Return: rr_RiskReturnAbstract  
Risk [Text Block] rr_RiskTextBlock

Sector Focus Risk. The Fund may invest a significant portion of its assets in one or more sectors and thus will be more susceptible to the risks affecting those sectors. While the Fund’s sector exposure is expected to vary over time based on the composition of the Index, the Fund anticipates that it may be subject to some or all of the risks described below. As of March 3, 2025, a significant portion of the Index consisted of companies in the Industrials Sector and Utilities Sector.

 

Industrials Sector Risk. The industrials sector consists of numerous sub-sectors, including the basic materials, capital goods, transportation and services sub-sectors. Industrial companies are affected by supply and demand both for their specific product or service and for industrial sector products in general. Government regulation, world events, exchange rates and economic conditions, technological developments and liabilities for environmental damage and general civil liabilities will likewise affect the performance of these companies. Aerospace and defense companies, a component of the industrial sector, can be significantly affected by government spending policies because companies involved in this sector rely, to a significant extent, on U.S. and foreign government demand for their products and services. Transportation securities, a component of the industrial sector, are cyclical and have occasional sharp price movements which may result from changes in the economy, fuel prices, labor agreements and insurance costs.

 

Utilities Sector Risk. The utilities sector may be adversely affected by changing commodity prices, government regulation stipulating rates charged by utilities, increased tariffs, changes in tax laws, interest rate fluctuations and changes in the cost of providing specific utility services. The utilities sector is also subject to potential terrorist attacks, including hacks and cyber-security attacks, natural disasters and severe weather conditions, as well as regulatory and operational burdens associated with the operation and maintenance of nuclear facilities. Government regulators monitor and control utility revenues and costs, and therefore may limit utility profits. In certain countries, regulatory authorities may also restrict a company’s access to new markets, thereby diminishing the company’s long-term prospects.

Range Nuclear Renaissance Index ETF | Small- and Mid-Capitalization Risk [Member]  
Risk/Return: rr_RiskReturnAbstract  
Risk [Text Block] rr_RiskTextBlock

Small- and Mid-Capitalization Risk. The small- and mid-capitalization companies in which the Fund invests may be more vulnerable to adverse business or economic events than larger, more established companies, and may underperform other segments of the market or the equity market as a whole. Securities of small- and mid-capitalization companies generally trade in lower volumes, are often more vulnerable to market volatility, and are subject to greater and more unpredictable price changes than larger capitalization stocks or the stock market as a whole.

Range Nuclear Renaissance Index ETF | Trading Risk [Member]  
Risk/Return: rr_RiskReturnAbstract  
Risk [Text Block] rr_RiskTextBlock

Trading Risk. Shares of the Fund may trade on the NYSE Arca, Inc. (the “Exchange”) above (premium) or below (discount) their NAV. The NAV of shares of the Fund will fluctuate with changes in the market value of the Fund’s holdings. The market prices of the Fund’s shares will fluctuate continuously throughout trading hours based on market supply and demand and may deviate significantly from the value of the Fund’s holdings, particularly in times of market stress, with the result that investors may pay more or receive less than the underlying value of the Fund shares bought or sold. When buying or selling shares in the secondary market, you may incur costs attributable to the difference between the highest price a buyer is willing to pay to purchase shares of the Fund (bid) and the lowest price a seller is willing to accept for shares of the Fund (ask), which is known as the bid-ask spread. In addition, although the Fund’s shares are currently listed on the Exchange, there can be no assurance that an active trading market for shares will develop or be maintained. Trading in Fund shares may be halted due to market conditions or for reasons that, in the view of the Exchange, make trading in shares of the Fund inadvisable. In stressed market conditions, the market for the Fund’s shares may become less liquid in response to deteriorating liquidity in the markets for the Fund’s underlying portfolio holdings. In such a circumstance, the Fund’s shares could trade at a premium or discount to their NAV.
