| Risk [Text Block] | Bitcoin Investment Risks. The Fund’s indirect investment in ABTC exposes it to the unique risks of bitcoin, which is an emerging innovation. Bitcoin’s price is highly volatile, and its market is influenced by the changing bitcoin network, fluctuating acceptance levels, and unpredictable usage trends. Not being a legal tender and operating outside central authority systems like banks, bitcoin faces potential government restrictions. For instance, some countries may limit or ban bitcoin transactions, negatively impacting its market value.
The risks associated with bitcoin include the possibility of fraud, theft, market manipulation, and security breaches in trading platforms. A small group of large bitcoin holders, known as “whales,” can significantly influence bitcoin’s price and may have the ability to manipulate the price. The largely unregulated nature of bitcoin and its trading venues heightens risks of fraudulent activities and market manipulation, which could affect bitcoin’s price. For example, if a group of miners gains control over a majority of the bitcoin network, they could manipulate transactions to their advantage. Historical instances have seen bitcoin trading venues shut down due to fraud or security breaches, often leaving investors without recourse and facing significant losses.
Updates to bitcoin’s software, proposed by developers, can lead to the creation of new digital assets, or “forks,” if not broadly adopted. This can impact bitcoin’s demand and the Fund’s performance. The extreme volatility of bitcoin’s market price can result in shareholder losses. Furthermore, the operation of bitcoin trading platforms may be disrupted or cease altogether due to various issues, further affecting bitcoin’s price and the Fund’s investments.
The value of bitcoin has historically been subject to significant speculation, making trading and investing in bitcoin reliant on market sentiment rather than traditional fundamental analysis.
Bitcoin’s price can be influenced by events unrelated to its security or utility, including instability in other speculative areas of the crypto/blockchain space, potentially leading to substantial declines in its value.
Risks associated with crypto asset trading platforms include fragmentation, regulatory non-compliance, and the possibility of enforcement actions by regulatory authorities, which could impact the valuation of bitcoin-linked derivatives held by the Fund.
The security of the Bitcoin Blockchain may be compromised if a single miner or group controls more than 50% of the network’s hashing power, where hashing power refers to the computational capacity used to validate and secure transactions on the blockchain.
Proposed changes to the bitcoin protocol may not be universally adopted, leading to the creation of competing blockchains (forks) with different assets and participants, exemplified by past forks like Bitcoin Cash and Bitcoin SV.
The Bitcoin Blockchain protocol may contain vulnerabilities that attackers could exploit to disrupt its operation, potentially compromising the security and reliability of the network.
Emerging alternative public blockchains, particularly those emphasizing privacy through technologies like zero-knowledge cryptography, pose risks and challenges to the dominance of the Bitcoin Blockchain as a payment system.
Common impediments to adopting the Bitcoin Blockchain as a payment network include slow transaction processing, variability in transaction fees, and the volatility of bitcoin’s price, which may deter widespread adoption by businesses and consumers.
The development and use of “Layer II solutions” are critical for the scalability and functionality of the Bitcoin Blockchain, but they also introduce risks such as off-chain transaction execution, which could affect transparency and security. Layer II solutions are off-chain protocols that improve scalability and reduce transaction costs by processing transactions outside the main blockchain network.
Adoption and use of other blockchains supporting advanced applications like smart contracts present challenges to the dominance of the Bitcoin Blockchain, potentially impacting its long-term relevance and utility in the evolving landscape of blockchain technology.

| Risk [Text Block] | Single Issuer Risk. Issuer-specific attributes may cause an investment in the Fund to be more volatile than a traditional pooled investment which diversifies risk or the market generally. The value of the Fund, which focuses on an individual security, 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. Additionally, the Fund will seek to employ its investment strategy as it relates to the underlying issuer regardless of whether there are significant corporate actions such as restructurings, enforcement activity, or acquisitions or periods adverse market, economic, or other conditions and will not seek to take temporary defensive positions during such periods.

| Prospectus [Line Items] | |||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||
| Risk [Text Block] | Compounding and Market Volatility Risk. The Fund has a daily leveraged investment objective and the Fund’s performance for periods greater than a trading day will be the result of each day’s returns compounded over the period, which is very likely to differ from two times (200%) the Underlying Security’s performance, before the Fund’s management fee and other expenses. Compounding affects all investments but has a more significant impact on funds that aim to replicate leveraged daily returns and that rebalance daily. For the Fund aiming to replicate two times the daily performance of an Underlying Security, if adverse daily performance of the Underlying Security reduces the amount of a shareholder’s investment, any further adverse daily performance will lead to a smaller dollar loss because the shareholder’s investment had already been reduced by the prior adverse performance. Equally, however, if favorable daily performance of the Underlying Security increases the amount of a shareholder’s investment, the dollar amount lost due to future adverse performance will increase because the shareholder’s investment has increased.
The effect of compounding becomes more pronounced as the Underlying Security’s volatility and the holding period increase. The impact of compounding will impact each shareholder differently depending on the period of time an investment in the Fund is held and the volatility of the Underlying Security during a shareholder’s holding period of an investment in the Fund.
The chart below provides examples of how the Underlying Security’s volatility could affect the Fund’s performance. The chart illustrates the impact of two factors that affect the Fund’s performance – the Underlying Security’s volatility and the Underlying Security’s performance. The Underlying Security’s performance shows the percentage change in the share price of the Underlying Security over the specified time period, while the Underlying Security’s volatility is a statistical measure of the magnitude of fluctuations in the returns during that time period. As illustrated below, even if the Underlying Security’s performance over two equal time periods is identical, different Underlying Security volatility (i.e., in magnitude of fluctuations in the share price of the Underlying Security) during the two time periods could result in drastically different Fund performance for the two time periods because of compounding daily returns during the time periods.
Fund performance for periods greater than one single day can be estimated given any set of assumptions for the following factors: a) the Underlying Security volatility; b) the Underlying Security performance; c) period of time; d) financing rates associated with leveraged exposure; and e) other Fund expenses. The chart shows estimated Fund returns for a number of combinations of Underlying Security volatility and Underlying Security performance over a one-year period. Performance shown in the chart assumes that: (i) there were no Fund expenses; (ii) borrowing/lending rates (to obtain leveraged exposure) of 0%. If Fund expenses and/or actual borrowing/lending rates were reflected the estimated returns would be different than those shown. Particularly during periods of higher Underlying Security volatility, compounding will cause results for periods longer than a trading day to vary from two times (200%) the performance of the Underlying Security.
As shown in the chart below, the Fund would be expected to lose 6.1% if there was no change in the share price of the Underlying Security over a one-year period during which the Underlying Security experienced annualized volatility of 25%. If the Underlying Security’s annualized volatility were to rise to 75%, the hypothetical loss for a one-year period would widen to approximately -43%. At higher ranges of volatility, there is a chance of a significant loss of value in the Fund, even if there were no change in the share price of the Underlying Security. For instance, if the Underlying Security’s annualized volatility is 100%, the Fund would be expected to lose 63.2% of its value, even if the cumulative Underlying Security change in the share price of the Underlying Security for the year was 0%.
Areas shaded red (or dark gray) represent those scenarios where the Fund can be expected to return less than two times (200%) the performance of the Underlying Security and those shaded green (or light gray) represent those scenarios where the Fund can be expected to return more than two times (200%) the performance of the Underlying Security. The Fund’s actual performance may be significantly better or worse than the performance shown below as a result of any of the factors discussed above or in the “Daily Correlation/Tracking Risk” below.
The Underlying Security’s five-year annualized historical volatility rate for the period ended March 6, 2026, was 132.80%. The Underlying Security’s annualized performance during this period was -83.74%. Historical Underlying Security volatility and performance are not indications of what Underlying Security volatility and performance will be in the future.

| Risk [Text Block] | Daily Correlation/Tracking Risk. There is no guarantee that the Fund will achieve a high degree of leveraged correlation to the Underlying Security and therefore achieve its daily leveraged investment objective. To achieve a high degree of leveraged correlation with the Underlying Security, the Fund seeks to rebalance its portfolio daily to keep exposure consistent with its daily leveraged investment objective. The possibility of the Fund being materially over- or under-exposed to the Underlying Security increases on days when the Underlying Security is volatile near the close of the trading day. Market disruptions, regulatory restrictions and extreme volatility will also adversely affect the Fund’s ability to adjust exposure to the required levels. If there is a significant intra-day market event and/or the Underlying Security experiences a significant increase or decline, the Fund may not meet its investment objective, be able to rebalance its portfolio appropriately, or may experience significant premiums or discounts, or widened bid-ask spreads.
The Fund may have difficulty achieving its daily leveraged investment objective due to fees, expenses, transaction costs, financing costs related to the use of derivatives, investments in ETFs, directly or indirectly, income items, valuation methodology, accounting standards and disruptions or illiquidity in the markets for the securities or derivatives held by the Fund. The Fund may be subject to large movements of assets into and out of the Fund, potentially resulting in the Fund being over- or under-exposed to the Underlying Security. The Fund may take or refrain from taking positions to improve the tax efficiency or to comply with various regulatory restrictions, either of which may negatively impact the Fund’s leveraged correlation to the Underlying Security.

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

| Risk [Text Block] | 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, leverage, imperfect daily correlations with underlying investments or the Fund’s other portfolio holdings, 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 imperfect correlation between the share price of the Underlying Security 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.
The Fund will be subject to regulatory constraints relating to level of value at risk that the Fund may incur through its derivative portfolio. To the extent the Fund exceeds these regulatory thresholds over an extended period, the Fund may determine that it is necessary to make adjustments to the Fund’s investment strategy, including the desired daily leveraged performance for the Fund.
In addition, the Fund’s investments in derivatives are subject to the following risks:

| Risk [Text Block] | Swap Agreements. The use of swap transactions is a highly specialized activity, which involves investment techniques and risks different from those associated with ordinary portfolio securities transactions. Whether the Fund will be successful in using swap agreements to achieve its investment goal depends on the ability of the Adviser to structure such swap agreements in accordance with the Fund’s investment objective and to identify counterparties for those swap agreements. If the Adviser is unable to enter into swap agreements that provide leveraged exposure to the Underlying Security, the Fund may not meet its stated investment objective. Additionally, any financing, borrowing or other costs associated with using swap transactions may also have the effect of lowering the Fund’s return.
The swap agreements in which the Fund invests are generally traded in the over-the-counter market, which generally has less transparency than exchange-traded derivatives instruments. In a standard swap transaction, two parties agree to exchange the return (or differentials in rates of return) earned or realized on particular predetermined reference assets or underlying securities or instruments. The gross return to be exchanged or swapped between the parties is calculated based on a notional amount or the return on or change in value of a particular dollar amount invested in a basket of securities.
If the Underlying Security has a dramatic move that causes a material decline in the Fund’s net assets, the terms of a swap agreement between the Fund and its counterparty may permit the counterparty to immediately close out the swap transaction with the Fund. In that event, the Fund may be unable to enter into another swap agreement or invest in other derivatives to achieve exposure consistent with the Fund’s investment objective. This may prevent the Fund from achieving its leveraged investment objective, even if the Underlying Security later reverses all or a portion of its movement.

| Prospectus [Line Items] | |||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||
| Risk [Text Block] | 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. The value of the options contracts in which the Fund invests are substantially influenced by the value of the Underlying Security. 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 as 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, as the Fund intends to continuously maintain indirect exposure to the Underlying Security through the use of options contracts, as the options contracts it holds are exercised or expire it will enter into new options contracts, a practice referred to as “rolling.” If the expiring options contracts do not generate proceeds enough to cover the cost of entering into new options contracts, the Fund may experience losses. The use of options to generate leverage introduces additional risks, including significant potential losses if the market moves unfavorably. The leverage inherent in options can amplify both gains and losses, leading to increased volatility and potential for substantial losses, particularly in periods of market uncertainty or low liquidity. Additionally, the Fund may incur losses if the value of the Underlying Security moves against its positions, potentially resulting in a complete loss of the premium paid.

| Prospectus [Line Items] | |||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||
| Risk [Text Block] | Counterparty Risk. The Fund is subject to counterparty risk by virtue of its investments in derivatives which exposes the Fund to the risk that the counterparty will not fulfill its obligation to the Fund. Counterparty risk may arise because of the counterparty’s financial condition (i.e., financial difficulties, bankruptcy, or insolvency), market activities and developments, or other reasons, whether foreseen or not. A counterparty’s inability to fulfill its obligation may result in significant financial loss to the Fund and the Fund may be unable to recover its investment from such counterparty or may obtain a limited and/or delayed recovery.
Counterparties may seek to hedge their exposure to individual clients (such as the Fund) by establishing offsetting exposures with other clients, however, there is no guarantee that counterparties will do so under all circumstances. Should a counterparty (e.g., a swap counterparty) terminate its relationship with the Fund, the Fund will seek to utilize other counterparties to seek to maintain its exposures. In addition, the Fund may use options contracts to seek to generate the leverage necessary to implement its strategy. The use of options contracts introduces distinct risks, including heightened volatility, particularly intraday. While options may provide an ancillary benefit of mitigating some losses under specific scenarios, such as severe market downturns, their inherent leverage and rapid price fluctuations can amplify the Fund’s performance volatility and lead to greater risks of substantial losses. Refer to “Derivatives Risk – Options Contracts” for additional information on the risks of investing in options.
In addition, the Fund may enter into swap agreements with a limited number of counterparties, which may increase the Fund’s exposure to counterparty credit risk. Further, there is a risk that no suitable counterparties will be willing to enter into, or continue to enter into, transactions with the Fund and, as a result, the Fund may not be able to achieve its investment objective.

| Prospectus [Line Items] | |||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||
| Risk [Text Block] | Intra-Day Investment Risk. The Fund seeks investment results from the close of the market on a given trading day until the close of the market on the subsequent trading day. The exact exposure of an investment in the Fund intraday in the secondary market is a function of the difference between the share price of the Underlying Security at the market close on the first trading day and the share price of the Underlying Security at the time of purchase. If the share price of the Underlying Security rises, the Fund’s net assets will rise by approximately twice the amount as the Fund’s exposure. Conversely, if the share price of the Underlying Security declines, the Fund’s net assets will decline by approximately two times the amount as the Fund’s exposure. Thus, an investor that purchases Shares intra-day may experience performance that is greater than, or less than, the Fund’s stated leveraged performance of the Underlying Security.
If there is a significant intra-day market event and/or the securities of the Underlying Security experience a significant increase or decrease, the Fund may not meet its investment objective or rebalance its portfolio appropriately.

| Prospectus [Line Items] | |||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||
| Risk [Text Block] | Fixed Income Securities Risk. When the Fund invests in fixed income securities, the value of your investment in the Fund will fluctuate with changes in interest rates. Typically, a rise in interest rates causes a decline in the value of fixed income securities owned by the Fund. In general, the market price of fixed income securities with longer maturities will increase or decrease more in response to changes in interest rates than shorter-term securities. Other risk factors include credit risk (the debtor may default), extension risk (an issuer may exercise its right to repay principal on a fixed rate obligation held by the Fund later than expected), and prepayment risk (the debtor may pay its obligation early, reducing the amount of interest payments). These risks could affect the value of a particular investment by the Fund, possibly causing the Fund’s Share price and total return to be reduced and fluctuate more than other types of investments.

| Risk [Text Block] | Rebalancing Risk. If for any reason the Fund is unable to rebalance all or a portion of its portfolio, or if all or a portion of the portfolio is rebalanced incorrectly, the Fund’s investment exposure may not be consistent with the Fund’s investment objective. In these instances, the Fund may have investment exposure to the Underlying Security that is significantly greater or less than its stated investment objective. As a result, the Fund may be exposed to leverage risk because it had not been properly rebalanced and may not achieve its investment objective.

| Risk [Text Block] | 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] | |||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||
| Risk [Text Block] | 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. The costs associated with cash redemptions may include brokerage costs that the Fund may not have incurred if it had made the redemptions in-kind. These costs could be imposed on the Fund, decreasing its NAV, to the extent these costs are not offset by a transaction fee payable by an authorized participant.

| Risk [Text Block] | Trading. Although Shares are listed on a national securities exchange, such as Cboe BZX Exchange, Inc. (the “Exchange”), and may be traded on U.S. exchanges other than the Exchange, there can be no assurance that Shares will trade with any volume, or at all, on any stock exchange. 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. This adverse effect on liquidity for the Fund’s shares may lead to wider bid-ask spreads and differences between the market price of the Fund’s shares and the underlying value of the shares.

| Risk [Text Block] | Economic and Market Risk. Economies and financial markets throughout the world are becoming increasingly interconnected, which increases the likelihood that events or conditions in one country or region will adversely impact markets or issuers in other countries or regions. Securities in the Fund’s portfolio may underperform in comparison to securities in the general financial markets, a particular financial market, or other asset classes, due to a number of factors, including inflation (or expectations for inflation), deflation (or expectations for deflation), interest rates, global demand for particular products or resources, market instability, financial system instability, debt crises and downgrades, embargoes, tariffs, sanctions and other trade barriers, regulatory events, other governmental trade or market control programs and related geopolitical events. In addition, the value of the Fund’s investments may be negatively affected by the occurrence of global events such as war, terrorism, environmental disasters, natural disasters or events, country instability, and infectious disease epidemics or pandemics. The imposition by the U.S. of tariffs on goods imported from foreign countries and reciprocal tariffs levied on U.S. goods by those countries also may lead to volatility and instability in domestic and foreign markets.

| Risk [Text Block] | High Portfolio Turnover Risk. Daily rebalancing of the Fund’s holdings pursuant to its daily investment objective causes a much greater number of portfolio transactions when compared to most ETFs. Additionally, active market trading of the Fund’s Shares on exchanges (such as the Exchange), could cause more frequent creation and redemption activities, which could increase the number of portfolio transactions. Frequent and active trading may lead to higher transaction costs because of increased broker commissions resulting from such transactions. In addition, there is the possibility of significantly increased short-term capital gains (which will be taxable to shareholders as ordinary income when distributed to them). The Fund calculates portfolio turnover without including the short-term cash instruments or derivative transactions that comprise the majority of the Fund’s trading. As such, if the Fund’s extensive use of derivative instruments were reflected, the calculated portfolio turnover rate would be significantly higher.

| Risk [Text Block] | Tracking Error Risk. Tracking error is the divergence of the Fund’s performance from that of its investment objective which aims to replicate two times the daily percentage change in the price of the Underlying Security. Tracking error may occur for a number of reasons. Tracking error may occur because of transaction costs, the Fund’s holding of cash, differences in accrual of dividends, being under- or overexposed to the Underlying Security or the need to meet new or existing regulatory requirements. Tracking error risk may be heightened during times of market volatility or other unusual market conditions such as market disruptions. The Fund may be required to deviate from its investment objectives, and therefore experience tracking error, as a result of market restrictions or other legal reasons, including regulatory limits or other restrictions on securities that may be purchased by the Adviser and its affiliates.

| Risk [Text Block] | Trading Halt Risk. Although the Underlying Security’s shares are listed for trading on an exchange, there can be no assurance that an active trading market for such shares will be available at all times and the Exchange may halt trading of such shares in certain circumstances. A halt in trading in the Underlying Security’s shares is expected, in turn, to result in a halt in the trading in the Fund’s Shares. Trading in the Underlying Security’s and/or Fund’s Shares on the Exchange may be halted due to market conditions or for reasons that, in the view of the Exchange, make trading in the Underlying Security’s and/or Fund’s Shares inadvisable. In addition, trading in Underlying Security’s and/or Fund’s Shares on an exchange is subject to trading halts caused by extraordinary market volatility pursuant to exchange “circuit breaker” rules.” In the event of a trading halt for an extended period of time, the Fund may be unable to execute arrangements with swap counterparties that are necessary to implement the Fund’s investment strategy.

| Risk [Text Block] | Tax Risk. The Fund intends to elect and to qualify each year to be treated as a regulated investment company (a “RIC”) under Subchapter M of the Internal Revenue Code of 1986, as amended (“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 swap contracts and options on shares of a single issuer does not exceed 25% of the Fund’s value at the close of any quarter. If the value of swap contracts and options on shares of a single issuer 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] | 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.

| Prospectus [Line Items] | |||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||
| Risk [Text Block] | Compounding and Market Volatility Risk. The Fund has a daily leveraged investment objective and the Fund’s performance for periods greater than a trading day will be the result of each day’s returns compounded over the period, which is very likely to differ from two times (200%) the Underlying Security’s performance, before the Fund’s management fee and other expenses. Compounding affects all investments but has a more significant impact on funds that aim to replicate leveraged daily returns and that rebalance daily. For the Fund aiming to replicate two times the daily performance of an Underlying Security, if adverse daily performance of the Underlying Security reduces the amount of a shareholder’s investment, any further adverse daily performance will lead to a smaller dollar loss because the shareholder’s investment had already been reduced by the prior adverse performance. Equally, however, if favorable daily performance of the Underlying Security increases the amount of a shareholder’s investment, the dollar amount lost due to future adverse performance will increase because the shareholder’s investment has increased.
The effect of compounding becomes more pronounced as the Underlying Security’s volatility and the holding period increase. The impact of compounding will impact each shareholder differently depending on the period of time an investment in the Fund is held and the volatility of the Underlying Security during a shareholder’s holding period of an investment in the Fund.
The chart below provides examples of how the Underlying Security’s volatility could affect the Fund’s performance. The chart illustrates the impact of two factors that affect the Fund’s performance – the Underlying Security’s volatility and the Underlying Security’s performance. The Underlying Security’s performance shows the percentage change in the share price of the Underlying Security over the specified time period, while the Underlying Security’s volatility is a statistical measure of the magnitude of fluctuations in the returns during that time period. As illustrated below, even if the Underlying Security’s performance over two equal time periods is identical, different Underlying Security volatility (i.e., in magnitude of fluctuations in the share price of the Underlying Security) during the two time periods could result in drastically different Fund performance for the two time periods because of compounding daily returns during the time periods.
Fund performance for periods greater than one single day can be estimated given any set of assumptions for the following factors: a) the Underlying Security volatility; b) the Underlying Security performance; c) period of time; d) financing rates associated with leveraged exposure; and e) other Fund expenses. The chart shows estimated Fund returns for a number of combinations of Underlying Security volatility and Underlying Security performance over a one-year period. Performance shown in the chart assumes that: (i) there were no Fund expenses; (ii) borrowing/lending rates (to obtain leveraged exposure) of 0%. If Fund expenses and/or actual borrowing/lending rates were reflected the estimated returns would be different than those shown. Particularly during periods of higher Underlying Security volatility, compounding will cause results for periods longer than a trading day to vary from two times (200%) the performance of the Underlying Security.
As shown in the chart below, the Fund would be expected to lose 6.1% if there was no change in the share price of the Underlying Security over a one-year period during which the Underlying Security experienced annualized volatility of 25%. If the Underlying Security’s annualized volatility were to rise to 75%, the hypothetical loss for a one-year period would widen to approximately -43%. At higher ranges of volatility, there is a chance of a significant loss of value in the Fund, even if there were no change in the share price of the Underlying Security. For instance, if the Underlying Security’s annualized volatility is 100%, the Fund would be expected to lose 63.2% of its value, even if the cumulative Underlying Security change in the share price of the Underlying Security for the year was 0%.
Areas shaded red (or dark gray) represent those scenarios where the Fund can be expected to return less than two times (200%) the performance of the Underlying Security and those shaded green (or light gray) represent those scenarios where the Fund can be expected to return more than two times (200%) the performance of the Underlying Security. The Fund’s actual performance may be significantly better or worse than the performance shown below as a result of any of the factors discussed above or in the “Daily Correlation/Tracking Risk” below.
The Underlying Security’s annualized historical volatility rate for the period from August 17, 2022 (the earliest date available) to March 6, 2026, was 116.81%. The Underlying Security’s annualized performance during this period was 45.92%. Historical Underlying Security volatility and performance are not indications of what Underlying Security volatility and performance will be in the future.

| Risk [Text Block] | Daily Correlation/Tracking Risk. There is no guarantee that the Fund will achieve a high degree of leveraged correlation to the Underlying Security and therefore achieve its daily leveraged investment objective. To achieve a high degree of leveraged correlation with the Underlying Security, the Fund seeks to rebalance its portfolio daily to keep exposure consistent with its daily leveraged investment objective. The possibility of the Fund being materially over- or under-exposed to the Underlying Security increases on days when the Underlying Security is volatile near the close of the trading day. Market disruptions, regulatory restrictions and extreme volatility will also adversely affect the Fund’s ability to adjust exposure to the required levels. If there is a significant intra-day market event and/or the Underlying Security experiences a significant increase or decline, the Fund may not meet its investment objective, be able to rebalance its portfolio appropriately, or may experience significant premiums or discounts, or widened bid-ask spreads.
The Fund may have difficulty achieving its daily leveraged investment objective due to fees, expenses, transaction costs, financing costs related to the use of derivatives, investments in ETFs, directly or indirectly, income items, valuation methodology, accounting standards and disruptions or illiquidity in the markets for the securities or derivatives held by the Fund. The Fund may be subject to large movements of assets into and out of the Fund, potentially resulting in the Fund being over- or under-exposed to the Underlying Security. The Fund may take or refrain from taking positions to improve the tax efficiency or to comply with various regulatory restrictions, either of which may negatively impact the Fund’s leveraged correlation to the Underlying Security.

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

| Risk [Text Block] | 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, leverage, imperfect daily correlations with underlying investments or the Fund’s other portfolio holdings, 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 imperfect correlation between the share price of the Underlying Security 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.
The Fund will be subject to regulatory constraints relating to level of value at risk that the Fund may incur through its derivative portfolio. To the extent the Fund exceeds these regulatory thresholds over an extended period, the Fund may determine that it is necessary to make adjustments to the Fund’s investment strategy, including the desired daily leveraged performance for the Fund.
In addition, the Fund’s investments in derivatives are subject to the following risks:

| Risk [Text Block] | Swap Agreements. The use of swap transactions is a highly specialized activity, which involves investment techniques and risks different from those associated with ordinary portfolio securities transactions. Whether the Fund will be successful in using swap agreements to achieve its investment goal depends on the ability of the Adviser to structure such swap agreements in accordance with the Fund’s investment objective and to identify counterparties for those swap agreements. If the Adviser is unable to enter into swap agreements that provide leveraged exposure to the Underlying Security, the Fund may not meet its stated investment objective. Additionally, any financing, borrowing or other costs associated with using swap transactions may also have the effect of lowering the Fund’s return.
The swap agreements in which the Fund invests are generally traded in the over-the-counter market, which generally has less transparency than exchange-traded derivatives instruments. In a standard swap transaction, two parties agree to exchange the return (or differentials in rates of return) earned or realized on particular predetermined reference assets or underlying securities or instruments. The gross return to be exchanged or swapped between the parties is calculated based on a notional amount or the return on or change in value of a particular dollar amount invested in a basket of securities.
If the Underlying Security has a dramatic move that causes a material decline in the Fund’s net assets, the terms of a swap agreement between the Fund and its counterparty may permit the counterparty to immediately close out the swap transaction with the Fund. In that event, the Fund may be unable to enter into another swap agreement or invest in other derivatives to achieve exposure consistent with the Fund’s investment objective. This may prevent the Fund from achieving its leveraged investment objective, even if the Underlying Security later reverses all or a portion of its movement.

| Risk [Text Block] | 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. The value of the options contracts in which the Fund invests are substantially influenced by the value of the Underlying Security. 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 as 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, as the Fund intends to continuously maintain indirect exposure to the Underlying Security through the use of options contracts, as the options contracts it holds are exercised or expire it will enter into new options contracts, a practice referred to as “rolling.” If the expiring options contracts do not generate proceeds enough to cover the cost of entering into new options contracts, the Fund may experience losses. The use of options to generate leverage introduces additional risks, including significant potential losses if the market moves unfavorably. The leverage inherent in options can amplify both gains and losses, leading to increased volatility and potential for substantial losses, particularly in periods of market uncertainty or low liquidity. Additionally, the Fund may incur losses if the value of the Underlying Security moves against its positions, potentially resulting in a complete loss of the premium paid.

| Risk [Text Block] | Counterparty Risk. The Fund is subject to counterparty risk by virtue of its investments in derivatives which exposes the Fund to the risk that the counterparty will not fulfill its obligation to the Fund. Counterparty risk may arise because of the counterparty’s financial condition (i.e., financial difficulties, bankruptcy, or insolvency), market activities and developments, or other reasons, whether foreseen or not. A counterparty’s inability to fulfill its obligation may result in significant financial loss to the Fund and the Fund may be unable to recover its investment from such counterparty or may obtain a limited and/or delayed recovery.
Counterparties may seek to hedge their exposure to individual clients (such as the Fund) by establishing offsetting exposures with other clients, however, there is no guarantee that counterparties will do so under all circumstances. Should a counterparty (e.g., a swap counterparty) terminate its relationship with the Fund, the Fund will seek to utilize other counterparties to seek to maintain its exposures. In addition, the Fund may use options contracts to seek to generate the leverage necessary to implement its strategy. The use of options contracts introduces distinct risks, including heightened volatility, particularly intraday. While options may provide an ancillary benefit of mitigating some losses under specific scenarios, such as severe market downturns, their inherent leverage and rapid price fluctuations can amplify the Fund’s performance volatility and lead to greater risks of substantial losses. Refer to “Derivatives Risk – Options Contracts” for additional information on the risks of investing in options.
In addition, the Fund may enter into swap agreements with a limited number of counterparties, which may increase the Fund’s exposure to counterparty credit risk. Further, there is a risk that no suitable counterparties will be willing to enter into, or continue to enter into, transactions with the Fund and, as a result, the Fund may not be able to achieve its investment objective.

The exact exposure of an investment in the Fund intraday in the secondary market is a function of the difference between the share price of the Underlying Security at the market close on the first trading day and the share price of the Underlying Security at the time of purchase. If the share price of the Underlying Security rises, the Fund’s net assets will rise by approximately twice the amount as the Fund’s exposure. Conversely, if the share price of the Underlying Security declines, the Fund’s net assets will decline by approximately two times the amount as the Fund’s exposure. Thus, an investor that purchases Shares intra-day may experience performance that is greater than, or less than, the Fund’s stated leveraged performance of the Underlying Security.
If there is a significant intra-day market event and/or the securities of the Underlying Security experience a significant increase or decrease, the Fund may not meet its investment objective or rebalance its portfolio appropriately.

| Risk [Text Block] | Fixed Income Securities Risk. When the Fund invests in fixed income securities, the value of your investment in the Fund will fluctuate with changes in interest rates. Typically, a rise in interest rates causes a decline in the value of fixed income securities owned by the Fund. In general, the market price of fixed income securities with longer maturities will increase or decrease more in response to changes in interest rates than shorter-term securities. Other risk factors include credit risk (the debtor may default), extension risk (an issuer may exercise its right to repay principal on a fixed rate obligation held by the Fund later than expected), and prepayment risk (the debtor may pay its obligation early, reducing the amount of interest payments). These risks could affect the value of a particular investment by the Fund, possibly causing the Fund’s Share price and total return to be reduced and fluctuate more than other types of investments.

| Risk [Text Block] | Rebalancing Risk. If for any reason the Fund is unable to rebalance all or a portion of its portfolio, or if all or a portion of the portfolio is rebalanced incorrectly, the Fund’s investment exposure may not be consistent with the Fund’s investment objective. In these instances, the Fund may have investment exposure to the Underlying Security that is significantly greater or less than its stated investment objective. As a result, the Fund may be exposed to leverage risk because it had not been properly rebalanced and may not achieve its investment objective.

| Risk [Text Block] | 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] | 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. The costs associated with cash redemptions may include brokerage costs that the Fund may not have incurred if it had made the redemptions in-kind. These costs could be imposed on the Fund, decreasing its NAV, to the extent these costs are not offset by a transaction fee payable by an authorized participant.

(the “Exchange”), and may be traded on U.S. exchanges other than the Exchange, there can be no assurance that Shares will trade with any volume, or at all, on any stock exchange. 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. This adverse effect on liquidity for the Fund’s shares may lead to wider bid-ask spreads and differences between the market price of the Fund’s shares and the underlying value of the shares.

| Risk [Text Block] | Economic and Market Risk. Economies and financial markets throughout the world are becoming increasingly interconnected, which increases the likelihood that events or conditions in one country or region will adversely impact markets or issuers in other countries or regions. Securities in the Fund’s portfolio may underperform in comparison to securities in the general financial markets, a particular financial market, or other asset classes, due to a number of factors, including inflation (or expectations for inflation), deflation (or expectations for deflation), interest rates, global demand for particular products or resources, market instability, financial system instability, debt crises and downgrades, embargoes, tariffs, sanctions and other trade barriers, regulatory events, other governmental trade or market control programs and related geopolitical events. In addition, the value of the Fund’s investments may be negatively affected by the occurrence of global events such as war, terrorism, environmental disasters, natural disasters or events, country instability, and infectious disease epidemics or pandemics. The imposition by the U.S. of tariffs on goods imported from foreign countries and reciprocal tariffs levied on U.S. goods by those countries also may lead to volatility and instability in domestic and foreign markets.

| Risk [Text Block] | High Portfolio Turnover Risk. Daily rebalancing of the Fund’s holdings pursuant to its daily investment objective causes a much greater number of portfolio transactions when compared to most ETFs. Additionally, active market trading of the Fund’s Shares on exchanges (such as the Exchange), could cause more frequent creation and redemption activities, which could increase the number of portfolio transactions. Frequent and active trading may lead to higher transaction costs because of increased broker commissions resulting from such transactions. In addition, there is the possibility of significantly increased short-term capital gains (which will be taxable to shareholders as ordinary income when distributed to them). The Fund calculates portfolio turnover without including the short-term cash instruments or derivative transactions that comprise the majority of the Fund’s trading. As such, if the Fund’s extensive use of derivative instruments were reflected, the calculated portfolio turnover rate would be significantly higher.

| Risk [Text Block] | Tracking Error Risk. Tracking error is the divergence of the Fund’s performance from that of its investment objective which aims to replicate two times the daily percentage change in the price of the Underlying Security. Tracking error may occur for a number of reasons. Tracking error may occur because of transaction costs, the Fund’s holding of cash, differences in accrual of dividends, being under- or overexposed to the Underlying Security or the need to meet new or existing regulatory requirements. Tracking error risk may be heightened during times of market volatility or other unusual market conditions such as market disruptions. The Fund may be required to deviate from its investment objectives, and therefore experience tracking error, as a result of market restrictions or other legal reasons, including regulatory limits or other restrictions on securities that may be purchased by the Adviser and its affiliates.

| Risk [Text Block] | Liquidity Risk. Some securities held by the Fund may be difficult to sell or be illiquid, particularly during times of market turmoil. 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 may prevent the Fund from limiting losses, realizing gains or achieving a high correlation with the Underlying Security. 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] | Trading Halt Risk. Although the Underlying Security’s shares are listed for trading on an exchange, there can be no assurance that an active trading market for such shares will be available at all times and the Exchange may halt trading of such shares in certain circumstances. A halt in trading in the Underlying Security’s shares is expected, in turn, to result in a halt in the trading in the Fund’s Shares. Trading in the Underlying Security’s and/or Fund’s Shares on the Exchange may be halted due to market conditions or for reasons that, in the view of the Exchange, make trading in the Underlying Security’s and/or Fund’s Shares inadvisable. In addition, trading in Underlying Security’s and/or Fund’s Shares on an exchange is subject to trading halts caused by extraordinary market volatility pursuant to exchange “circuit breaker” rules.” In the event of a trading halt for an extended period of time, the Fund may be unable to execute arrangements with swap counterparties that are necessary to implement the Fund’s investment strategy.

| Risk [Text Block] | Tax Risk. The Fund intends to elect and to qualify each year to be treated as a regulated investment company (a “RIC”) under Subchapter M of the Internal Revenue Code of 1986, as amended (“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 swap contracts and options on shares of a single issuer does not exceed 25% of the Fund’s value at the close of any quarter. If the value of swap contracts and options on shares of a single issuer 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] | 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.

| Prospectus [Line Items] | |||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||
| Risk [Text Block] | Compounding and Market Volatility Risk. The Fund has a daily leveraged investment objective and the Fund’s performance for periods greater than a trading day will be the result of each day’s returns compounded over the period, which is very likely to differ from two times (200%) the Underlying Security’s performance, before the Fund’s management fee and other expenses. Compounding affects all investments but has a more significant impact on funds that aim to replicate leveraged daily returns and that rebalance daily. For the Fund aiming to replicate two times the daily performance of an Underlying Security, if adverse daily performance of the Underlying Security reduces the amount of a shareholder’s investment, any further adverse daily performance will lead to a smaller dollar loss because the shareholder’s investment had already been reduced by the prior adverse performance. Equally, however, if favorable daily performance of the Underlying Security increases the amount of a shareholder’s investment, the dollar amount lost due to future adverse performance will increase because the shareholder’s investment has increased.
The effect of compounding becomes more pronounced as the Underlying Security’s volatility and the holding period increase. The impact of compounding will impact each shareholder differently depending on the period of time an investment in the Fund is held and the volatility of the Underlying Security during a shareholder’s holding period of an investment in the Fund.
The chart below provides examples of how the Underlying Security’s volatility could affect the Fund’s performance. The chart illustrates the impact of two factors that affect the Fund’s performance – the Underlying Security’s volatility and the Underlying Security’s performance. The Underlying Security’s performance shows the percentage change in the share price of the Underlying Security over the specified time period, while the Underlying Security’s volatility is a statistical measure of the magnitude of fluctuations in the returns during that time period. As illustrated below, even if the Underlying Security’s performance over two equal time periods is identical, different Underlying Security volatility (i.e., in magnitude of fluctuations in the share price of the Underlying Security) during the two time periods could result in drastically different Fund performance for the two time periods because of compounding daily returns during the time periods.
Fund performance for periods greater than one single day can be estimated given any set of assumptions for the following factors: a) the Underlying Security volatility; b) the Underlying Security performance; c) period of time; d) financing rates associated with leveraged exposure; and e) other Fund expenses. The chart shows estimated Fund returns for a number of combinations of Underlying Security volatility and Underlying Security performance over a one-year period. Performance shown in the chart assumes that: (i) there were no Fund expenses; (ii) borrowing/lending rates (to obtain leveraged exposure) of 0%. If Fund expenses and/or actual borrowing/lending rates were reflected the estimated returns would be different than those shown. Particularly during periods of higher Underlying Security volatility, compounding will cause results for periods longer than a trading day to vary from two times (200%) the performance of the Underlying Security.
As shown in the chart below, the Fund would be expected to lose 6.1% if there was no change in the share price of the Underlying Security over a one-year period during which the Underlying Security experienced annualized volatility of 25%. If the Underlying Security’s annualized volatility were to rise to 75%, the hypothetical loss for a one-year period would widen to approximately -43%. At higher ranges of volatility, there is a chance of a significant loss of value in the Fund, even if there were no change in the share price of the Underlying Security. For instance, if the Underlying Security’s annualized volatility is 100%, the Fund would be expected to lose 63.2% of its value, even if the cumulative Underlying Security change in the share price of the Underlying Security for the year was 0%.
Areas shaded red (or dark gray) represent those scenarios where the Fund can be expected to return less than two times (200%) the performance of the Underlying Security and those shaded green (or light gray) represent those scenarios where the Fund can be expected to return more than two times (200%) the performance of the Underlying Security. The Fund’s actual performance may be significantly better or worse than the performance shown below as a result of any of the factors discussed above or in the “Daily Correlation/Tracking Risk” below.
The Underlying Security’s five-year annualized historical volatility rate for the period ended March 6, 2026, was 129.76%. The Underlying Security’s annualized performance during this period was -14.23%. Historical Underlying Security volatility and performance are not indications of what Underlying Security volatility and performance will be in the future.

| Risk [Text Block] | Daily Correlation/Tracking Risk. There is no guarantee that the Fund will achieve a high degree of leveraged correlation to the Underlying Security and therefore achieve its daily leveraged investment objective. To achieve a high degree of leveraged correlation with the Underlying Security, the Fund seeks to rebalance its portfolio daily to keep exposure consistent with its daily leveraged investment objective. The possibility of the Fund being materially over- or under-exposed to the Underlying Security increases on days when the Underlying Security is volatile near the close of the trading day. Market disruptions, regulatory restrictions and extreme volatility will also adversely affect the Fund’s ability to adjust exposure to the required levels. If there is a significant intra-day market event and/or the Underlying Security experiences a significant increase or decline, the Fund may not meet its investment objective, be able to rebalance its portfolio appropriately, or may experience significant premiums or discounts, or widened bid-ask spreads.
The Fund may have difficulty achieving its daily leveraged investment objective due to fees, expenses, transaction costs, financing costs related to the use of derivatives, investments in ETFs, directly or indirectly, income items, valuation methodology, accounting standards and disruptions or illiquidity in the markets for the securities or derivatives held by the Fund. The Fund may be subject to large movements of assets into and out of the Fund, potentially resulting in the Fund being over- or under-exposed to the Underlying Security. The Fund may take or refrain from taking positions to improve the tax efficiency or to comply with various regulatory restrictions, either of which may negatively impact the Fund’s leveraged correlation to the Underlying Security.

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

| Risk [Text Block] | 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, leverage, imperfect daily correlations with underlying investments or the Fund’s other portfolio holdings, 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 imperfect correlation between the share price of the Underlying Security 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.
The Fund will be subject to regulatory constraints relating to level of value at risk that the Fund may incur through its derivative portfolio. To the extent the Fund exceeds these regulatory thresholds over an extended period, the Fund may determine that it is necessary to make adjustments to the Fund’s investment strategy, including the desired daily leveraged performance for the Fund.
In addition, the Fund’s investments in derivatives are subject to the following risks:

| Prospectus [Line Items] | |||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||
| Risk [Text Block] | Swap Agreements. The use of swap transactions is a highly specialized activity, which involves investment techniques and risks different from those associated with ordinary portfolio securities transactions. Whether the Fund will be successful in using swap agreements to achieve its investment goal depends on the ability of the Adviser to structure such swap agreements in accordance with the Fund’s investment objective and to identify counterparties for those swap agreements. If the Adviser is unable to enter into swap agreements that provide leveraged exposure to the Underlying Security, the Fund may not meet its stated investment objective. Additionally, any financing, borrowing or other costs associated with using swap transactions may also have the effect of lowering the Fund’s return.
The swap agreements in which the Fund invests are generally traded in the over-the-counter market, which generally has less transparency than exchange-traded derivatives instruments. In a standard swap transaction, two parties agree to exchange the return (or differentials in rates of return) earned or realized on particular predetermined reference assets or underlying securities or instruments. The gross return to be exchanged or swapped between the parties is calculated based on a notional amount or the return on or change in value of a particular dollar amount invested in a basket of securities.
If the Underlying Security has a dramatic move that causes a material decline in the Fund’s net assets, the terms of a swap agreement between the Fund and its counterparty may permit the counterparty to immediately close out the swap transaction with the Fund. In that event, the Fund may be unable to enter into another swap agreement or invest in other derivatives to achieve exposure consistent with the Fund’s investment objective. This may prevent the Fund from achieving its leveraged investment objective, even if the Underlying Security later reverses all or a portion of its movement.

| Prospectus [Line Items] | |||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||
| Risk [Text Block] | 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. The value of the options contracts in which the Fund invests are substantially influenced by the value of the Underlying Security. 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 as 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, as the Fund intends to continuously maintain indirect exposure to the Underlying Security through the use of options contracts, as the options contracts it holds are exercised or expire it will enter into new options contracts, a practice referred to as “rolling.” If the expiring options contracts do not generate proceeds enough to cover the cost of entering into new options contracts, the Fund may experience losses. The use of options to generate leverage introduces additional risks, including significant potential losses if the market moves unfavorably. The leverage inherent in options can amplify both gains and losses, leading to increased volatility and potential for substantial losses, particularly in periods of market uncertainty or low liquidity. Additionally, the Fund may incur losses if the value of the Underlying Security moves against its positions, potentially resulting in a complete loss of the premium paid.

| Prospectus [Line Items] | |||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||
| Risk [Text Block] | Counterparty Risk. The Fund is subject to counterparty risk by virtue of its investments in derivatives which exposes the Fund to the risk that the counterparty will not fulfill its obligation to the Fund. Counterparty risk may arise because of the counterparty’s financial condition (i.e., financial difficulties, bankruptcy, or insolvency), market activities and developments, or other reasons, whether foreseen or not. A counterparty’s inability to fulfill its obligation may result in significant financial loss to the Fund and the Fund may be unable to recover its investment from such counterparty or may obtain a limited and/or delayed recovery.
Counterparties may seek to hedge their exposure to individual clients (such as the Fund) by establishing offsetting exposures with other clients, however, there is no guarantee that counterparties will do so under all circumstances. Should a counterparty (e.g., a swap counterparty) terminate its relationship with the Fund, the Fund will seek to utilize other counterparties to seek to maintain its exposures. In addition, the Fund may use options contracts to seek to generate the leverage necessary to implement its strategy. The use of options contracts introduces distinct risks, including heightened volatility, particularly intraday. While options may provide an ancillary benefit of mitigating some losses under specific scenarios, such as severe market downturns, their inherent leverage and rapid price fluctuations can amplify the Fund’s performance volatility and lead to greater risks of substantial losses. Refer to “Derivatives Risk – Options Contracts” for additional information on the risks of investing in options.
In addition, the Fund may enter into swap agreements with a limited number of counterparties, which may increase the Fund’s exposure to counterparty credit risk. Further, there is a risk that no suitable counterparties will be willing to enter into, or continue to enter into, transactions with the Fund and, as a result, the Fund may not be able to achieve its investment objective.

| Risk [Text Block] | Intra-Day Investment Risk. The Fund seeks investment results from the close of the market on a given trading day until the close of the market on the subsequent trading day. The exact exposure of an investment in the Fund intraday in the secondary market is a function of the difference between the share price of the Underlying Security at the market close on the first trading day and the share price of the Underlying Security at the time of purchase. If the share price of the Underlying Security rises, the Fund’s net assets will rise by approximately twice the amount as the Fund’s exposure. Conversely, if the share price of the Underlying Security declines, the Fund’s net assets will decline by approximately two times the amount as the Fund’s exposure. Thus, an investor that purchases Shares intra-day may experience performance that is greater than, or less than, the Fund’s stated leveraged performance of the Underlying Security.
If there is a significant intra-day market event and/or the securities of the Underlying Security experience a significant increase or decrease, the Fund may not meet its investment objective or rebalance its portfolio appropriately.

| Risk [Text Block] | Fixed Income Securities Risk. When the Fund invests in fixed income securities, the value of your investment in the Fund will fluctuate with changes in interest rates. Typically, a rise in interest rates causes a decline in the value of fixed income securities owned by the Fund. In general, the market price of fixed income securities with longer maturities will increase or decrease more in response to changes in interest rates than shorter-term securities. Other risk factors include credit risk (the debtor may default), extension risk (an issuer may exercise its right to repay principal on a fixed rate obligation held by the Fund later than expected), and prepayment risk (the debtor may pay its obligation early, reducing the amount of interest payments). These risks could affect the value of a particular investment by the Fund, possibly causing the Fund’s Share price and total return to be reduced and fluctuate more than other types of investments.

| Risk [Text Block] | Rebalancing Risk. If for any reason the Fund is unable to rebalance all or a portion of its portfolio, or if all or a portion of the portfolio is rebalanced incorrectly, the Fund’s investment exposure may not be consistent with the Fund’s investment objective. In these instances, the Fund may have investment exposure to the Underlying Security that is significantly greater or less than its stated investment objective. As a result, the Fund may be exposed to leverage risk because it had not been properly rebalanced and may not achieve its investment objective.

| Risk [Text Block] | 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] | 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. The costs associated with cash redemptions may include brokerage costs that the Fund may not have incurred if it had made the redemptions in-kind. These costs could be imposed on the Fund, decreasing its NAV, to the extent these costs are not offset by a transaction fee payable by an authorized participant.

| Risk [Text Block] | Trading. Although Shares are listed on a national securities exchange, such as Cboe BZX Exchange, Inc. (the “Exchange”), and may be traded on U.S. exchanges other than the Exchange, there can be no assurance that Shares will trade with any volume, or at all, on any stock exchange. 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. This adverse effect on liquidity for the Fund’s shares may lead to wider bid-ask spreads and differences between the market price of the Fund’s shares and the underlying value of the shares.

In certain circumstances, such as the disruption of the orderly markets for the financial instruments in which the Fund invests, the Fund might not be able to acquire or dispose of certain holdings quickly or at prices that represent true market value in the judgment of the Adviser. Markets for the financial instruments in which the Fund invests may be disrupted by a number of events, including but not limited to economic crises, health crises, natural disasters, excessive volatility, new legislation, or regulatory changes inside or outside of the U.S. These situations may have an impact on the liquidity of the Fund’s own shares.”

| Risk [Text Block] | Economic and Market Risk. Economies and financial markets throughout the world are becoming increasingly interconnected, which increases the likelihood that events or conditions in one country or region will adversely impact markets or issuers in other countries or regions. Securities in the Fund’s portfolio may underperform in comparison to securities in the general financial markets, a particular financial market, or other asset classes, due to a number of factors, including inflation (or expectations for inflation), deflation (or expectations for deflation), interest rates, global demand for particular products or resources, market instability, financial system instability, debt crises and downgrades, embargoes, tariffs, sanctions and other trade barriers, regulatory events, other governmental trade or market control programs and related geopolitical events. In addition, the value of the Fund’s investments may be negatively affected by the occurrence of global events such as war, terrorism, environmental disasters, natural disasters or events, country instability, and infectious disease epidemics or pandemics. The imposition by the U.S. of tariffs on goods imported from foreign countries and reciprocal tariffs levied on U.S. goods by those countries also may lead to volatility and instability in domestic and foreign markets.

| Risk [Text Block] | High Portfolio Turnover Risk. Daily rebalancing of the Fund’s holdings pursuant to its daily investment objective causes a much greater number of portfolio transactions when compared to most ETFs. Additionally, active market trading of the Fund’s Shares on exchanges (such as the Exchange), could cause more frequent creation and redemption activities, which could increase the number of portfolio transactions. Frequent and active trading may lead to higher transaction costs because of increased broker commissions resulting from such transactions. In addition, there is the possibility of significantly increased short-term capital gains (which will be taxable to shareholders as ordinary income when distributed to them). The Fund calculates portfolio turnover without including the short-term cash instruments or derivative transactions that comprise the majority of the Fund’s trading. As such, if the Fund’s extensive use of derivative instruments were reflected, the calculated portfolio turnover rate would be significantly higher.

| Risk [Text Block] | Tracking Error Risk. Tracking error is the divergence of the Fund’s performance from that of its investment objective which aims to replicate two times the daily percentage change in the price of the Underlying Security. Tracking error may occur for a number of reasons. Tracking error may occur because of transaction costs, the Fund’s holding of cash, differences in accrual of dividends, being under- or overexposed to the Underlying Security or the need to meet new or existing regulatory requirements. Tracking error risk may be heightened during times of market volatility or other unusual market conditions such as market disruptions. The Fund may be required to deviate from its investment objectives, and therefore experience tracking error, as a result of market restrictions or other legal reasons, including regulatory limits or other restrictions on securities that may be purchased by the Adviser and its affiliates.

| Risk [Text Block] | Liquidity Risk. Some securities held by the Fund may be difficult to sell or be illiquid, particularly during times of market turmoil. 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 may prevent the Fund from limiting losses, realizing gains or achieving a high correlation with the Underlying Security. 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.

Although the Underlying Security’s shares are listed for trading on an exchange, there can be no assurance that an active trading market for such shares will be available at all times and the Exchange may halt trading of such shares in certain circumstances. A halt in trading in the Underlying Security’s shares is expected, in turn, to result in a halt in the trading in the Fund’s Shares. Trading in the Underlying Security’s and/or Fund’s Shares on the Exchange may be halted due to market conditions or for reasons that, in the view of the Exchange, make trading in the Underlying Security’s and/or Fund’s Shares inadvisable. In addition, trading in Underlying Security’s and/or Fund’s Shares on an exchange is subject to trading halts caused by extraordinary market volatility pursuant to exchange “circuit breaker” rules.” In the event of a trading halt for an extended period of time, the Fund may be unable to execute arrangements with swap counterparties that are necessary to implement the Fund’s investment strategy.

| Risk [Text Block] | Tax Risk. The Fund intends to elect and to qualify each year to be treated as a regulated investment company (a “RIC”) under Subchapter M of the Internal Revenue Code of 1986, as amended (“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 swap contracts and options on shares of a single issuer does not exceed 25% of the Fund’s value at the close of any quarter. If the value of swap contracts and options on shares of a single issuer 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] | 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] | Single Issuer Risk. Issuer-specific attributes may cause an investment in the Fund to be more volatile than a traditional pooled investment which diversifies risk or the market generally. The value of the Fund, which focuses on an individual security, 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. Additionally, the Fund will seek to employ its investment strategy as it relates to the underlying issuer regardless of whether there are significant corporate actions such as restructurings, enforcement activity, or acquisitions or periods adverse market, economic, or other conditions and will not seek to take temporary defensive positions during such periods.

| Prospectus [Line Items] | |||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||
| Risk [Text Block] | Compounding and Market Volatility Risk. The Fund has a daily leveraged investment objective and the Fund’s performance for periods greater than a trading day will be the result of each day’s returns compounded over the period, which is very likely to differ from two times (200%) the Underlying Security’s performance, before the Fund’s management fee and other expenses. Compounding affects all investments but has a more significant impact on funds that aim to replicate leveraged daily returns and that rebalance daily. For the Fund aiming to replicate two times the daily performance of an Underlying Security, if adverse daily performance of the Underlying Security reduces the amount of a shareholder’s investment, any further adverse daily performance will lead to a smaller dollar loss because the shareholder’s investment had already been reduced by the prior adverse performance. Equally, however, if favorable daily performance of the Underlying Security increases the amount of a shareholder’s investment, the dollar amount lost due to future adverse performance will increase because the shareholder’s investment has increased.
The effect of compounding becomes more pronounced as the Underlying Security’s volatility and the holding period increase. The impact of compounding will impact each shareholder differently depending on the period of time an investment in the Fund is held and the volatility of the Underlying Security during a shareholder’s holding period of an investment in the Fund.
The chart below provides examples of how the Underlying Security’s volatility could affect the Fund’s performance. The chart illustrates the impact of two factors that affect the Fund’s performance – the Underlying Security’s volatility and the Underlying Security’s performance. The Underlying Security’s performance shows the percentage change in the share price of the Underlying Security over the specified time period, while the Underlying Security’s volatility is a statistical measure of the magnitude of fluctuations in the returns during that time period. As illustrated below, even if the Underlying Security’s performance over two equal time periods is identical, different Underlying Security volatility (i.e., in magnitude of fluctuations in the share price of the Underlying Security) during the two time periods could result in drastically different Fund performance for the two time periods because of compounding daily returns during the time periods.
Fund performance for periods greater than one single day can be estimated given any set of assumptions for the following factors: a) the Underlying Security volatility; b) the Underlying Security performance; c) period of time; d) financing rates associated with leveraged exposure; and e) other Fund expenses. The chart shows estimated Fund returns for a number of combinations of Underlying Security volatility and Underlying Security performance over a one-year period. Performance shown in the chart assumes that: (i) there were no Fund expenses; (ii) borrowing/lending rates (to obtain leveraged exposure) of 0%. If Fund expenses and/or actual borrowing/lending rates were reflected the estimated returns would be different than those shown. Particularly during periods of higher Underlying Security volatility, compounding will cause results for periods longer than a trading day to vary from two times (200%) the performance of the Underlying Security.
As shown in the chart below, the Fund would be expected to lose 6.1% if there was no change in the share price of the Underlying Security over a one-year period during which the Underlying Security experienced annualized volatility of 25%. If the Underlying Security’s annualized volatility were to rise to 75%, the hypothetical loss for a one-year period would widen to approximately -43%. At higher ranges of volatility, there is a chance of a significant loss of value in the Fund, even if there were no change in the share price of the Underlying Security. For instance, if the Underlying Security’s annualized volatility is 100%, the Fund would be expected to lose 63.2% of its value, even if the cumulative Underlying Security change in the share price of the Underlying Security for the year was 0%.
Areas shaded red (or dark gray) represent those scenarios where the Fund can be expected to return less than two times (200%) the performance of the Underlying Security and those shaded green (or light gray) represent those scenarios where the Fund can be expected to return more than two times (200%) the performance of the Underlying Security. The Fund’s actual performance may be significantly better or worse than the performance shown below as a result of any of the factors discussed above or in the “Daily Correlation/Tracking Risk” below.
The Underlying Security’s annualized historical volatility rate for the period from December 16, 2025 (the earliest date available) to March 6, 2026, was 86.30%. The Underlying Security’s annualized performance during this period was 522.05%. Historical Underlying Security volatility and performance are not indications of what Underlying Security volatility and performance will be in the future.

| Risk [Text Block] | Daily Correlation/Tracking Risk. There is no guarantee that the Fund will achieve a high degree of leveraged correlation to the Underlying Security and therefore achieve its daily leveraged investment objective. To achieve a high degree of leveraged correlation with the Underlying Security, the Fund seeks to rebalance its portfolio daily to keep exposure consistent with its daily leveraged investment objective. The possibility of the Fund being materially over- or under-exposed to the Underlying Security increases on days when the Underlying Security is volatile near the close of the trading day. Market disruptions, regulatory restrictions and extreme volatility will also adversely affect the Fund’s ability to adjust exposure to the required levels. If there is a significant intra-day market event and/or the Underlying Security experiences a significant increase or decline, the Fund may not meet its investment objective, be able to rebalance its portfolio appropriately, or may experience significant premiums or discounts, or widened bid-ask spreads.
The Fund may have difficulty achieving its daily leveraged investment objective due to fees, expenses, transaction costs, financing costs related to the use of derivatives, investments in ETFs, directly or indirectly, income items, valuation methodology, accounting standards and disruptions or illiquidity in the markets for the securities or derivatives held by the Fund. The Fund may be subject to large movements of assets into and out of the Fund, potentially resulting in the Fund being over- or under-exposed to the Underlying Security. The Fund may take or refrain from taking positions to improve the tax efficiency or to comply with various regulatory restrictions, either of which may negatively impact the Fund’s leveraged correlation to the Underlying Security.

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

| Risk [Text Block] | 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, leverage, imperfect daily correlations with underlying investments or the Fund’s other portfolio holdings, 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 imperfect correlation between the share price of the Underlying Security 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.
The Fund will be subject to regulatory constraints relating to level of value at risk that the Fund may incur through its derivative portfolio. To the extent the Fund exceeds these regulatory thresholds over an extended period, the Fund may determine that it is necessary to make adjustments to the Fund’s investment strategy, including the desired daily leveraged performance for the Fund.
In addition, the Fund’s investments in derivatives are subject to the following risks:

| Risk [Text Block] | Swap Agreements. The use of swap transactions is a highly specialized activity, which involves investment techniques and risks different from those associated with ordinary portfolio securities transactions. Whether the Fund will be successful in using swap agreements to achieve its investment goal depends on the ability of the Adviser to structure such swap agreements in accordance with the Fund’s investment objective and to identify counterparties for those swap agreements. If the Adviser is unable to enter into swap agreements that provide leveraged exposure to the Underlying Security, the Fund may not meet its stated investment objective. Additionally, any financing, borrowing or other costs associated with using swap transactions may also have the effect of lowering the Fund’s return.
The swap agreements in which the Fund invests are generally traded in the over-the-counter market, which generally has less transparency than exchange-traded derivatives instruments. In a standard swap transaction, two parties agree to exchange the return (or differentials in rates of return) earned or realized on particular predetermined reference assets or underlying securities or instruments. The gross return to be exchanged or swapped between the parties is calculated based on a notional amount or the return on or change in value of a particular dollar amount invested in a basket of securities.
If the Underlying Security has a dramatic move that causes a material decline in the Fund’s net assets, the terms of a swap agreement between the Fund and its counterparty may permit the counterparty to immediately close out the swap transaction with the Fund. In that event, the Fund may be unable to enter into another swap agreement or invest in other derivatives to achieve exposure consistent with the Fund’s investment objective. This may prevent the Fund from achieving its leveraged investment objective, even if the Underlying Security later reverses all or a portion of its movement.

| Risk [Text Block] | 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. The value of the options contracts in which the Fund invests are substantially influenced by the value of the Underlying Security. 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 as 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, as the Fund intends to continuously maintain indirect exposure to the Underlying Security through the use of options contracts, as the options contracts it holds are exercised or expire it will enter into new options contracts, a practice referred to as “rolling.” If the expiring options contracts do not generate proceeds enough to cover the cost of entering into new options contracts, the Fund may experience losses. The use of options to generate leverage introduces additional risks, including significant potential losses if the market moves unfavorably. The leverage inherent in options can amplify both gains and losses, leading to increased volatility and potential for substantial losses, particularly in periods of market uncertainty or low liquidity. Additionally, the Fund may incur losses if the value of the Underlying Security moves against its positions, potentially resulting in a complete loss of the premium paid.

| Prospectus [Line Items] | |||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||
| Risk [Text Block] | Counterparty Risk. The Fund is subject to counterparty risk by virtue of its investments in derivatives which exposes the Fund to the risk that the counterparty will not fulfill its obligation to the Fund. Counterparty risk may arise because of the counterparty’s financial condition (i.e., financial difficulties, bankruptcy, or insolvency), market activities and developments, or other reasons, whether foreseen or not. A counterparty’s inability to fulfill its obligation may result in significant financial loss to the Fund and the Fund may be unable to recover its investment from such counterparty or may obtain a limited and/or delayed recovery.
Counterparties may seek to hedge their exposure to individual clients (such as the Fund) by establishing offsetting exposures with other clients, however, there is no guarantee that counterparties will do so under all circumstances. Should a counterparty (e.g., a swap counterparty) terminate its relationship with the Fund, the Fund will seek to utilize other counterparties to seek to maintain its exposures. In addition, the Fund may use options contracts to seek to generate the leverage necessary to implement its strategy. The use of options contracts introduces distinct risks, including heightened volatility, particularly intraday. While options may provide an ancillary benefit of mitigating some losses under specific scenarios, such as severe market downturns, their inherent leverage and rapid price fluctuations can amplify the Fund’s performance volatility and lead to greater risks of substantial losses. Refer to “Derivatives Risk – Options Contracts” for additional information on the risks of investing in options.
In addition, the Fund may enter into swap agreements with a limited number of counterparties, which may increase the Fund’s exposure to counterparty credit risk. Further, there is a risk that no suitable counterparties will be willing to enter into, or continue to enter into, transactions with the Fund and, as a result, the Fund may not be able to achieve its investment objective.

| Risk [Text Block] | Intra-Day Investment Risk. The Fund seeks investment results from the close of the market on a given trading day until the close of the market on the subsequent trading day. The exact exposure of an investment in the Fund intraday in the secondary market is a function of the difference between the share price of the Underlying Security at the market close on the first trading day and the share price of the Underlying Security at the time of purchase. If the share price of the Underlying Security rises, the Fund’s net assets will rise by approximately twice the amount as the Fund’s exposure. Conversely, if the share price of the Underlying Security declines, the Fund’s net assets will decline by approximately two times the amount as the Fund’s exposure. Thus, an investor that purchases Shares intra-day may experience performance that is greater than, or less than, the Fund’s stated leveraged performance of the Underlying Security.
If there is a significant intra-day market event and/or the securities of the Underlying Security experience a significant increase or decrease, the Fund may not meet its investment objective or rebalance its portfolio appropriately.

| Risk [Text Block] | Fixed Income Securities Risk. When the Fund invests in fixed income securities, the value of your investment in the Fund will fluctuate with changes in interest rates. Typically, a rise in interest rates causes a decline in the value of fixed income securities owned by the Fund. In general, the market price of fixed income securities with longer maturities will increase or decrease more in response to changes in interest rates than shorter-term securities. Other risk factors include credit risk (the debtor may default), extension risk (an issuer may exercise its right to repay principal on a fixed rate obligation held by the Fund later than expected), and prepayment risk (the debtor may pay its obligation early, reducing the amount of interest payments). These risks could affect the value of a particular investment by the Fund, possibly causing the Fund’s Share price and total return to be reduced and fluctuate more than other types of investments.

| Risk [Text Block] | Rebalancing Risk. If for any reason the Fund is unable to rebalance all or a portion of its portfolio, or if all or a portion of the portfolio is rebalanced incorrectly, the Fund’s investment exposure may not be consistent with the Fund’s investment objective. In these instances, the Fund may have investment exposure to the Underlying Security that is significantly greater or less than its stated investment objective. As a result, the Fund may be exposed to leverage risk because it had not been properly rebalanced and may not achieve its investment objective.

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] | 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. The costs associated with cash redemptions may include brokerage costs that the Fund may not have incurred if it had made the redemptions in-kind. These costs could be imposed on the Fund, decreasing its NAV, to the extent these costs are not offset by a transaction fee payable by an authorized participant.

(the “Exchange”), and may be traded on U.S. exchanges other than the Exchange, there can be no assurance that Shares will trade with any volume, or at all, on any stock exchange. 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. This adverse effect on liquidity for the Fund’s shares may lead to wider bid-ask spreads and differences between the market price of the Fund’s shares and the underlying value of the shares.

| Risk [Text Block] | Economic and Market Risk. Economies and financial markets throughout the world are becoming increasingly interconnected, which increases the likelihood that events or conditions in one country or region will adversely impact markets or issuers in other countries or regions. Securities in the Fund’s portfolio may underperform in comparison to securities in the general financial markets, a particular financial market, or other asset classes, due to a number of factors, including inflation (or expectations for inflation), deflation (or expectations for deflation), interest rates, global demand for particular products or resources, market instability, financial system instability, debt crises and downgrades, embargoes, tariffs, sanctions and other trade barriers, regulatory events, other governmental trade or market control programs and related geopolitical events. In addition, the value of the Fund’s investments may be negatively affected by the occurrence of global events such as war, terrorism, environmental disasters, natural disasters or events, country instability, and infectious disease epidemics or pandemics. The imposition by the U.S. of tariffs on goods imported from foreign countries and reciprocal tariffs levied on U.S. goods by those countries also may lead to volatility and instability in domestic and foreign markets.

| Risk [Text Block] | High Portfolio Turnover Risk. Daily rebalancing of the Fund’s holdings pursuant to its daily investment objective causes a much greater number of portfolio transactions when compared to most ETFs. Additionally, active market trading of the Fund’s Shares on exchanges (such as the Exchange), could cause more frequent creation and redemption activities, which could increase the number of portfolio transactions. Frequent and active trading may lead to higher transaction costs because of increased broker commissions resulting from such transactions. In addition, there is the possibility of significantly increased short-term capital gains (which will be taxable to shareholders as ordinary income when distributed to them). The Fund calculates portfolio turnover without including the short-term cash instruments or derivative transactions that comprise the majority of the Fund’s trading. As such, if the Fund’s extensive use of derivative instruments were reflected, the calculated portfolio turnover rate would be significantly higher.

| Risk [Text Block] | Tracking Error Risk. Tracking error is the divergence of the Fund’s performance from that of its investment objective which aims to replicate two times the daily percentage change in the price of the Underlying Security. Tracking error may occur for a number of reasons. Tracking error may occur because of transaction costs, the Fund’s holding of cash, differences in accrual of dividends, being under- or overexposed to the Underlying Security or the need to meet new or existing regulatory requirements. Tracking error risk may be heightened during times of market volatility or other unusual market conditions such as market disruptions. The Fund may be required to deviate from its investment objectives, and therefore experience tracking error, as a result of market restrictions or other legal reasons, including regulatory limits or other restrictions on securities that may be purchased by the Adviser and its affiliates.

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 may prevent the Fund from limiting losses, realizing gains or achieving a high correlation with the Underlying Security. 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] | Trading Halt Risk. Although the Underlying Security’s shares are listed for trading on an exchange, there can be no assurance that an active trading market for such shares will be available at all times and the Exchange may halt trading of such shares in certain circumstances. A halt in trading in the Underlying Security’s shares is expected, in turn, to result in a halt in the trading in the Fund’s Shares. Trading in the Underlying Security’s and/or Fund’s Shares on the Exchange may be halted due to market conditions or for reasons that, in the view of the Exchange, make trading in the Underlying Security’s and/or Fund’s Shares inadvisable. In addition, trading in Underlying Security’s and/or Fund’s Shares on an exchange is subject to trading halts caused by extraordinary market volatility pursuant to exchange “circuit breaker” rules.” In the event of a trading halt for an extended period of time, the Fund may be unable to execute arrangements with swap counterparties that are necessary to implement the Fund’s investment strategy.

| Risk [Text Block] | Tax Risk. The Fund intends to elect and to qualify each year to be treated as a regulated investment company (a “RIC”) under Subchapter M of the Internal Revenue Code of 1986, as amended (“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 swap contracts and options on shares of a single issuer does not exceed 25% of the Fund’s value at the close of any quarter. If the value of swap contracts and options on shares of a single issuer 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] | 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] | Single Issuer Risk. Issuer-specific attributes may cause an investment in the Fund to be more volatile than a traditional pooled investment which diversifies risk or the market generally. The value of the Fund, which focuses on an individual security, 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. Additionally, the Fund will seek to employ its investment strategy as it relates to the underlying issuer regardless of whether there are significant corporate actions such as restructurings, enforcement activity, or acquisitions or periods adverse market, economic, or other conditions and will not seek to take temporary defensive positions during such periods.

| Prospectus [Line Items] | |||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||
| Risk [Text Block] | Compounding and Market Volatility Risk. The Fund has a daily leveraged investment objective and the Fund’s performance for periods greater than a trading day will be the result of each day’s returns compounded over the period, which is very likely to differ from two times (200%) the Underlying Security’s performance, before the Fund’s management fee and other expenses. Compounding affects all investments but has a more significant impact on funds that aim to replicate leveraged daily returns and that rebalance daily. For the Fund aiming to replicate two times the daily performance of an Underlying Security, if adverse daily performance of the Underlying Security reduces the amount of a shareholder’s investment, any further adverse daily performance will lead to a smaller dollar loss because the shareholder’s investment had already been reduced by the prior adverse performance. Equally, however, if favorable daily performance of the Underlying Security increases the amount of a shareholder’s investment, the dollar amount lost due to future adverse performance will increase because the shareholder’s investment has increased.
The effect of compounding becomes more pronounced as the Underlying Security’s volatility and the holding period increase. The impact of compounding will impact each shareholder differently depending on the period of time an investment in the Fund is held and the volatility of the Underlying Security during a shareholder’s holding period of an investment in the Fund.
The chart below provides examples of how the Underlying Security’s volatility could affect the Fund’s performance. The chart illustrates the impact of two factors that affect the Fund’s performance – the Underlying Security’s volatility and the Underlying Security’s performance. The Underlying Security’s performance shows the percentage change in the share price of the Underlying Security over the specified time period, while the Underlying Security’s volatility is a statistical measure of the magnitude of fluctuations in the returns during that time period. As illustrated below, even if the Underlying Security’s performance over two equal time periods is identical, different Underlying Security volatility (i.e., in magnitude of fluctuations in the share price of the Underlying Security) during the two time periods could result in drastically different Fund performance for the two time periods because of compounding daily returns during the time periods.
Fund performance for periods greater than one single day can be estimated given any set of assumptions for the following factors: a) the Underlying Security volatility; b) the Underlying Security performance; c) period of time; d) financing rates associated with leveraged exposure; and e) other Fund expenses. The chart shows estimated Fund returns for a number of combinations of Underlying Security volatility and Underlying Security performance over a one-year period. Performance shown in the chart assumes that: (i) there were no Fund expenses; (ii) borrowing/lending rates (to obtain leveraged exposure) of 0%. If Fund expenses and/or actual borrowing/lending rates were reflected the estimated returns would be different than those shown. Particularly during periods of higher Underlying Security volatility, compounding will cause results for periods longer than a trading day to vary from two times (200%) the performance of the Underlying Security.
As shown in the chart below, the Fund would be expected to lose 6.1% if there was no change in the share price of the Underlying Security over a one-year period during which the Underlying Security experienced annualized volatility of 25%. If the Underlying Security’s annualized volatility were to rise to 75%, the hypothetical loss for a one-year period would widen to approximately -43%. At higher ranges of volatility, there is a chance of a significant loss of value in the Fund, even if there were no change in the share price of the Underlying Security. For instance, if the Underlying Security’s annualized volatility is 100%, the Fund would be expected to lose 63.2% of its value, even if the cumulative Underlying Security change in the share price of the Underlying Security for the year was 0%.
Areas shaded red (or dark gray) represent those scenarios where the Fund can be expected to return less than two times (200%) the performance of the Underlying Security and those shaded green (or light gray) represent those scenarios where the Fund can be expected to return more than two times (200%) the performance of the Underlying Security. The Fund’s actual performance may be significantly better or worse than the performance shown below as a result of any of the factors discussed above or in the “Daily Correlation/Tracking Risk” below.
The Underlying Security’s five-year annualized historical volatility rate for the period ended March 6, 2026, was 56.87%. The Underlying Security’s annualized performance during this period was -20.33%. Historical Underlying Security volatility and performance are not indications of what Underlying Security volatility and performance will be in the future.

| Risk [Text Block] | Daily Correlation/Tracking Risk. There is no guarantee that the Fund will achieve a high degree of leveraged correlation to the Underlying Security and therefore achieve its daily leveraged investment objective. To achieve a high degree of leveraged correlation with the Underlying Security, the Fund seeks to rebalance its portfolio daily to keep exposure consistent with its daily leveraged investment objective. The possibility of the Fund being materially over- or under-exposed to the Underlying Security increases on days when the Underlying Security is volatile near the close of the trading day. Market disruptions, regulatory restrictions and extreme volatility will also adversely affect the Fund’s ability to adjust exposure to the required levels. If there is a significant intra-day market event and/or the Underlying Security experiences a significant increase or decline, the Fund may not meet its investment objective, be able to rebalance its portfolio appropriately, or may experience significant premiums or discounts, or widened bid-ask spreads.
The Fund may have difficulty achieving its daily leveraged investment objective due to fees, expenses, transaction costs, financing costs related to the use of derivatives, investments in ETFs, directly or indirectly, income items, valuation methodology, accounting standards and disruptions or illiquidity in the markets for the securities or derivatives held by the Fund. The Fund may be subject to large movements of assets into and out of the Fund, potentially resulting in the Fund being over- or under-exposed to the Underlying Security. The Fund may take or refrain from taking positions to improve the tax efficiency or to comply with various regulatory restrictions, either of which may negatively impact the Fund’s leveraged correlation to the Underlying Security.

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

| Risk [Text Block] | 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, leverage, imperfect daily correlations with underlying investments or the Fund’s other portfolio holdings, 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 imperfect correlation between the share price of the Underlying Security 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.
The Fund will be subject to regulatory constraints relating to level of value at risk that the Fund may incur through its derivative portfolio. To the extent the Fund exceeds these regulatory thresholds over an extended period, the Fund may determine that it is necessary to make adjustments to the Fund’s investment strategy, including the desired daily leveraged performance for the Fund.
In addition, the Fund’s investments in derivatives are subject to the following risks:

| Risk [Text Block] | Swap Agreements. The use of swap transactions is a highly specialized activity, which involves investment techniques and risks different from those associated with ordinary portfolio securities transactions. Whether the Fund will be successful in using swap agreements to achieve its investment goal depends on the ability of the Adviser to structure such swap agreements in accordance with the Fund’s investment objective and to identify counterparties for those swap agreements. If the Adviser is unable to enter into swap agreements that provide leveraged exposure to the Underlying Security, the Fund may not meet its stated investment objective. Additionally, any financing, borrowing or other costs associated with using swap transactions may also have the effect of lowering the Fund’s return.
The swap agreements in which the Fund invests are generally traded in the over-the-counter market, which generally has less transparency than exchange-traded derivatives instruments. In a standard swap transaction, two parties agree to exchange the return (or differentials in rates of return) earned or realized on particular predetermined reference assets or underlying securities or instruments. The gross return to be exchanged or swapped between the parties is calculated based on a notional amount or the return on or change in value of a particular dollar amount invested in a basket of securities.
If the Underlying Security has a dramatic move that causes a material decline in the Fund’s net assets, the terms of a swap agreement between the Fund and its counterparty may permit the counterparty to immediately close out the swap transaction with the Fund. In that event, the Fund may be unable to enter into another swap agreement or invest in other derivatives to achieve exposure consistent with the Fund’s investment objective. This may prevent the Fund from achieving its leveraged investment objective, even if the Underlying Security later reverses all or a portion of its movement.

| Risk [Text Block] | 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. The value of the options contracts in which the Fund invests are substantially influenced by the value of the Underlying Security. 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 as 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, as the Fund intends to continuously maintain indirect exposure to the Underlying Security through the use of options contracts, as the options contracts it holds are exercised or expire it will enter into new options contracts, a practice referred to as “rolling.” If the expiring options contracts do not generate proceeds enough to cover the cost of entering into new options contracts, the Fund may experience losses. The use of options to generate leverage introduces additional risks, including significant potential losses if the market moves unfavorably. The leverage inherent in options can amplify both gains and losses, leading to increased volatility and potential for substantial losses, particularly in periods of market uncertainty or low liquidity. Additionally, the Fund may incur losses if the value of the Underlying Security moves against its positions, potentially resulting in a complete loss of the premium paid.

| Risk [Text Block] | Counterparty Risk. The Fund is subject to counterparty risk by virtue of its investments in derivatives which exposes the Fund to the risk that the counterparty will not fulfill its obligation to the Fund. Counterparty risk may arise because of the counterparty’s financial condition (i.e., financial difficulties, bankruptcy, or insolvency), market activities and developments, or other reasons, whether foreseen or not. A counterparty’s inability to fulfill its obligation may result in significant financial loss to the Fund and the Fund may be unable to recover its investment from such counterparty or may obtain a limited and/or delayed recovery.
Counterparties may seek to hedge their exposure to individual clients (such as the Fund) by establishing offsetting exposures with other clients, however, there is no guarantee that counterparties will do so under all circumstances. Should a counterparty (e.g., a swap counterparty) terminate its relationship with the Fund, the Fund will seek to utilize other counterparties to seek to maintain its exposures. In addition, the Fund may use options contracts to seek to generate the leverage necessary to implement its strategy. The use of options contracts introduces distinct risks, including heightened volatility, particularly intraday. While options may provide an ancillary benefit of mitigating some losses under specific scenarios, such as severe market downturns, their inherent leverage and rapid price fluctuations can amplify the Fund’s performance volatility and lead to greater risks of substantial losses. Refer to “Derivatives Risk – Options Contracts” for additional information on the risks of investing in options.
In addition, the Fund may enter into swap agreements with a limited number of counterparties, which may increase the Fund’s exposure to counterparty credit risk. Further, there is a risk that no suitable counterparties will be willing to enter into, or continue to enter into, transactions with the Fund and, as a result, the Fund may not be able to achieve its investment objective.

| Risk [Text Block] | Intra-Day Investment Risk. The Fund seeks investment results from the close of the market on a given trading day until the close of the market on the subsequent trading day. The exact exposure of an investment in the Fund intraday in the secondary market is a function of the difference between the share price of the Underlying Security at the market close on the first trading day and the share price of the Underlying Security at the time of purchase. If the share price of the Underlying Security rises, the Fund’s net assets will rise by approximately twice the amount as the Fund’s exposure. Conversely, if the share price of the Underlying Security declines, the Fund’s net assets will decline by approximately two times the amount as the Fund’s exposure. Thus, an investor that purchases Shares intra-day may experience performance that is greater than, or less than, the Fund’s stated leveraged performance of the Underlying Security.
If there is a significant intra-day market event and/or the securities of the Underlying Security experience a significant increase or decrease, the Fund may not meet its investment objective or rebalance its portfolio appropriately.

| Risk [Text Block] | Fixed Income Securities Risk. When the Fund invests in fixed income securities, the value of your investment in the Fund will fluctuate with changes in interest rates. Typically, a rise in interest rates causes a decline in the value of fixed income securities owned by the Fund. In general, the market price of fixed income securities with longer maturities will increase or decrease more in response to changes in interest rates than shorter-term securities. Other risk factors include credit risk (the debtor may default), extension risk (an issuer may exercise its right to repay principal on a fixed rate obligation held by the Fund later than expected), and prepayment risk (the debtor may pay its obligation early, reducing the amount of interest payments). These risks could affect the value of a particular investment by the Fund, possibly causing the Fund’s Share price and total return to be reduced and fluctuate more than other types of investments.

In these instances, the Fund may have investment exposure to the Underlying Security that is significantly greater or less than its stated investment objective. As a result, the Fund may be exposed to leverage risk because it had not been properly rebalanced and may not achieve its investment objective.

| Risk [Text Block] | 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] | 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. The costs associated with cash redemptions may include brokerage costs that the Fund may not have incurred if it had made the redemptions in-kind. These costs could be imposed on the Fund, decreasing its NAV, to the extent these costs are not offset by a transaction fee payable by an authorized participant.

(the “Exchange”), and may be traded on U.S. exchanges other than the Exchange, there can be no assurance that Shares will trade with any volume, or at all, on any stock exchange. 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. This adverse effect on liquidity for the Fund’s shares may lead to wider bid-ask spreads and differences between the market price of the Fund’s shares and the underlying value of the shares.

| Risk [Text Block] | Economic and Market Risk. Economies and financial markets throughout the world are becoming increasingly interconnected, which increases the likelihood that events or conditions in one country or region will adversely impact markets or issuers in other countries or regions. Securities in the Fund’s portfolio may underperform in comparison to securities in the general financial markets, a particular financial market, or other asset classes, due to a number of factors, including inflation (or expectations for inflation), deflation (or expectations for deflation), interest rates, global demand for particular products or resources, market instability, financial system instability, debt crises and downgrades, embargoes, tariffs, sanctions and other trade barriers, regulatory events, other governmental trade or market control programs and related geopolitical events. In addition, the value of the Fund’s investments may be negatively affected by the occurrence of global events such as war, terrorism, environmental disasters, natural disasters or events, country instability, and infectious disease epidemics or pandemics. The imposition by the U.S. of tariffs on goods imported from foreign countries and reciprocal tariffs levied on U.S. goods by those countries also may lead to volatility and instability in domestic and foreign markets.

| Risk [Text Block] | High Portfolio Turnover Risk. Daily rebalancing of the Fund’s holdings pursuant to its daily investment objective causes a much greater number of portfolio transactions when compared to most ETFs. Additionally, active market trading of the Fund’s Shares on exchanges (such as the Exchange), could cause more frequent creation and redemption activities, which could increase the number of portfolio transactions. Frequent and active trading may lead to higher transaction costs because of increased broker commissions resulting from such transactions. In addition, there is the possibility of significantly increased short-term capital gains (which will be taxable to shareholders as ordinary income when distributed to them). The Fund calculates portfolio turnover without including the short-term cash instruments or derivative transactions that comprise the majority of the Fund’s trading. As such, if the Fund’s extensive use of derivative instruments were reflected, the calculated portfolio turnover rate would be significantly higher.

| Risk [Text Block] | Tracking Error Risk. Tracking error is the divergence of the Fund’s performance from that of its investment objective which aims to replicate two times the daily percentage change in the price of the Underlying Security. Tracking error may occur for a number of reasons. Tracking error may occur because of transaction costs, the Fund’s holding of cash, differences in accrual of dividends, being under- or overexposed to the Underlying Security or the need to meet new or existing regulatory requirements. Tracking error risk may be heightened during times of market volatility or other unusual market conditions such as market disruptions. The Fund may be required to deviate from its investment objectives, and therefore experience tracking error, as a result of market restrictions or other legal reasons, including regulatory limits or other restrictions on securities that may be purchased by the Adviser and its affiliates.

Although the Underlying Security’s shares are listed for trading on an exchange, there can be no assurance that an active trading market for such shares will be available at all times and the Exchange may halt trading of such shares in certain circumstances. A halt in trading in the Underlying Security’s shares is expected, in turn, to result in a halt in the trading in the Fund’s Shares. Trading in the Underlying Security’s and/or Fund’s Shares on the Exchange may be halted due to market conditions or for reasons that, in the view of the Exchange, make trading in the Underlying Security’s and/or Fund’s Shares inadvisable. In addition, trading in Underlying Security’s and/or Fund’s Shares on an exchange is subject to trading halts caused by extraordinary market volatility pursuant to exchange “circuit breaker” rules.” In the event of a trading halt for an extended period of time, the Fund may be unable to execute arrangements with swap counterparties that are necessary to implement the Fund’s investment strategy.

| Risk [Text Block] | Tax Risk. The Fund intends to elect and to qualify each year to be treated as a regulated investment company (a “RIC”) under Subchapter M of the Internal Revenue Code of 1986, as amended (“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 swap contracts and options on shares of a single issuer does not exceed 25% of the Fund’s value at the close of any quarter. If the value of swap contracts and options on shares of a single issuer 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] | 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.

| Prospectus [Line Items] | |||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||
| Risk [Text Block] | Compounding and Market Volatility Risk. The Fund has a daily leveraged investment objective and the Fund’s performance for periods greater than a trading day will be the result of each day’s returns compounded over the period, which is very likely to differ from two times (200%) the Underlying Security’s performance, before the Fund’s management fee and other expenses. Compounding affects all investments but has a more significant impact on funds that aim to replicate leveraged daily returns and that rebalance daily. For the Fund aiming to replicate two times the daily performance of an Underlying Security, if adverse daily performance of the Underlying Security reduces the amount of a shareholder’s investment, any further adverse daily performance will lead to a smaller dollar loss because the shareholder’s investment had already been reduced by the prior adverse performance. Equally, however, if favorable daily performance of the Underlying Security increases the amount of a shareholder’s investment, the dollar amount lost due to future adverse performance will increase because the shareholder’s investment has increased.
The effect of compounding becomes more pronounced as the Underlying Security’s volatility and the holding period increase. The impact of compounding will impact each shareholder differently depending on the period of time an investment in the Fund is held and the volatility of the Underlying Security during a shareholder’s holding period of an investment in the Fund.
The chart below provides examples of how the Underlying Security’s volatility could affect the Fund’s performance. The chart illustrates the impact of two factors that affect the Fund’s performance – the Underlying Security’s volatility and the Underlying Security’s performance. The Underlying Security’s performance shows the percentage change in the share price of the Underlying Security over the specified time period, while the Underlying Security’s volatility is a statistical measure of the magnitude of fluctuations in the returns during that time period. As illustrated below, even if the Underlying Security’s performance over two equal time periods is identical, different Underlying Security volatility (i.e., in magnitude of fluctuations in the share price of the Underlying Security) during the two time periods could result in drastically different Fund performance for the two time periods because of compounding daily returns during the time periods.
Fund performance for periods greater than one single day can be estimated given any set of assumptions for the following factors: a) the Underlying Security volatility; b) the Underlying Security performance; c) period of time; d) financing rates associated with leveraged exposure; and e) other Fund expenses. The chart shows estimated Fund returns for a number of combinations of Underlying Security volatility and Underlying Security performance over a one-year period. Performance shown in the chart assumes that: (i) there were no Fund expenses; (ii) borrowing/lending rates (to obtain leveraged exposure) of 0%. If Fund expenses and/or actual borrowing/lending rates were reflected the estimated returns would be different than those shown. Particularly during periods of higher Underlying Security volatility, compounding will cause results for periods longer than a trading day to vary from two times (200%) the performance of the Underlying Security.
As shown in the chart below, the Fund would be expected to lose 6.1% if there was no change in the share price of the Underlying Security over a one-year period during which the Underlying Security experienced annualized volatility of 25%. If the Underlying Security’s annualized volatility were to rise to 75%, the hypothetical loss for a one-year period would widen to approximately -43%. At higher ranges of volatility, there is a chance of a significant loss of value in the Fund, even if there were no change in the share price of the Underlying Security. For instance, if the Underlying Security’s annualized volatility is 100%, the Fund would be expected to lose 63.2% of its value, even if the cumulative Underlying Security change in the share price of the Underlying Security for the year was 0%.
Areas shaded red (or dark gray) represent those scenarios where the Fund can be expected to return less than two times (200%) the performance of the Underlying Security and those shaded green (or light gray) represent those scenarios where the Fund can be expected to return more than two times (200%) the performance of the Underlying Security. The Fund’s actual performance may be significantly better or worse than the performance shown below as a result of any of the factors discussed above or in the “Daily Correlation/Tracking Risk” below.
The Underlying Security’s five-year annualized historical volatility rate for the period ended March 6, 2026, was 67.27%. The Underlying Security’s annualized performance during this period was -21.22%. Historical Underlying Security volatility and performance are not indications of what Underlying Security volatility and performance will be in the future.

| Risk [Text Block] | Daily Correlation/Tracking Risk. There is no guarantee that the Fund will achieve a high degree of leveraged correlation to the Underlying Security and therefore achieve its daily leveraged investment objective. To achieve a high degree of leveraged correlation with the Underlying Security, the Fund seeks to rebalance its portfolio daily to keep exposure consistent with its daily leveraged investment objective. The possibility of the Fund being materially over- or under-exposed to the Underlying Security increases on days when the Underlying Security is volatile near the close of the trading day. Market disruptions, regulatory restrictions and extreme volatility will also adversely affect the Fund’s ability to adjust exposure to the required levels. If there is a significant intra-day market event and/or the Underlying Security experiences a significant increase or decline, the Fund may not meet its investment objective, be able to rebalance its portfolio appropriately, or may experience significant premiums or discounts, or widened bid-ask spreads.
The Fund may have difficulty achieving its daily leveraged investment objective due to fees, expenses, transaction costs, financing costs related to the use of derivatives, investments in ETFs, directly or indirectly, income items, valuation methodology, accounting standards and disruptions or illiquidity in the markets for the securities or derivatives held by the Fund. The Fund may be subject to large movements of assets into and out of the Fund, potentially resulting in the Fund being over- or under-exposed to the Underlying Security. The Fund may take or refrain from taking positions to improve the tax efficiency or to comply with various regulatory restrictions, either of which may negatively impact the Fund’s leveraged correlation to the Underlying Security.

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

| Risk [Text Block] | 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, leverage, imperfect daily correlations with underlying investments or the Fund’s other portfolio holdings, 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 imperfect correlation between the share price of the Underlying Security 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.
The Fund will be subject to regulatory constraints relating to level of value at risk that the Fund may incur through its derivative portfolio. To the extent the Fund exceeds these regulatory thresholds over an extended period, the Fund may determine that it is necessary to make adjustments to the Fund’s investment strategy, including the desired daily leveraged performance for the Fund.
In addition, the Fund’s investments in derivatives are subject to the following risks:

| Prospectus [Line Items] | |||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||
| Risk [Text Block] | Swap Agreements. The use of swap transactions is a highly specialized activity, which involves investment techniques and risks different from those associated with ordinary portfolio securities transactions. Whether the Fund will be successful in using swap agreements to achieve its investment goal depends on the ability of the Adviser to structure such swap agreements in accordance with the Fund’s investment objective and to identify counterparties for those swap agreements. If the Adviser is unable to enter into swap agreements that provide leveraged exposure to the Underlying Security, the Fund may not meet its stated investment objective. Additionally, any financing, borrowing or other costs associated with using swap transactions may also have the effect of lowering the Fund’s return.
The swap agreements in which the Fund invests are generally traded in the over-the-counter market, which generally has less transparency than exchange-traded derivatives instruments. In a standard swap transaction, two parties agree to exchange the return (or differentials in rates of return) earned or realized on particular predetermined reference assets or underlying securities or instruments. The gross return to be exchanged or swapped between the parties is calculated based on a notional amount or the return on or change in value of a particular dollar amount invested in a basket of securities.
If the Underlying Security has a dramatic move that causes a material decline in the Fund’s net assets, the terms of a swap agreement between the Fund and its counterparty may permit the counterparty to immediately close out the swap transaction with the Fund. In that event, the Fund may be unable to enter into another swap agreement or invest in other derivatives to achieve exposure consistent with the Fund’s investment objective. This may prevent the Fund from achieving its leveraged investment objective, even if the Underlying Security later reverses all or a portion of its movement.

| Prospectus [Line Items] | |||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||
| Risk [Text Block] | 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. The value of the options contracts in which the Fund invests are substantially influenced by the value of the Underlying Security. 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 as 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, as the Fund intends to continuously maintain indirect exposure to the Underlying Security through the use of options contracts, as the options contracts it holds are exercised or expire it will enter into new options contracts, a practice referred to as “rolling.” If the expiring options contracts do not generate proceeds enough to cover the cost of entering into new options contracts, the Fund may experience losses. The use of options to generate leverage introduces additional risks, including significant potential losses if the market moves unfavorably. The leverage inherent in options can amplify both gains and losses, leading to increased volatility and potential for substantial losses, particularly in periods of market uncertainty or low liquidity. Additionally, the Fund may incur losses if the value of the Underlying Security moves against its positions, potentially resulting in a complete loss of the premium paid.

| Prospectus [Line Items] | |||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||
| Risk [Text Block] | Counterparty Risk. The Fund is subject to counterparty risk by virtue of its investments in derivatives which exposes the Fund to the risk that the counterparty will not fulfill its obligation to the Fund. Counterparty risk may arise because of the counterparty’s financial condition (i.e., financial difficulties, bankruptcy, or insolvency), market activities and developments, or other reasons, whether foreseen or not. A counterparty’s inability to fulfill its obligation may result in significant financial loss to the Fund and the Fund may be unable to recover its investment from such counterparty or may obtain a limited and/or delayed recovery.
Counterparties may seek to hedge their exposure to individual clients (such as the Fund) by establishing offsetting exposures with other clients, however, there is no guarantee that counterparties will do so under all circumstances. Should a counterparty (e.g., a swap counterparty) terminate its relationship with the Fund, the Fund will seek to utilize other counterparties to seek to maintain its exposures. In addition, the Fund may use options contracts to seek to generate the leverage necessary to implement its strategy. The use of options contracts introduces distinct risks, including heightened volatility, particularly intraday. While options may provide an ancillary benefit of mitigating some losses under specific scenarios, such as severe market downturns, their inherent leverage and rapid price fluctuations can amplify the Fund’s performance volatility and lead to greater risks of substantial losses. Refer to “Derivatives Risk – Options Contracts” for additional information on the risks of investing in options.
In addition, the Fund may enter into swap agreements with a limited number of counterparties, which may increase the Fund’s exposure to counterparty credit risk. Further, there is a risk that no suitable counterparties will be willing to enter into, or continue to enter into, transactions with the Fund and, as a result, the Fund may not be able to achieve its investment objective.

| Prospectus [Line Items] | |||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||
| Risk [Text Block] | Intra-Day Investment Risk. The Fund seeks investment results from the close of the market on a given trading day until the close of the market on the subsequent trading day. The exact exposure of an investment in the Fund intraday in the secondary market is a function of the difference between the share price of the Underlying Security at the market close on the first trading day and the share price of the Underlying Security at the time of purchase. If the share price of the Underlying Security rises, the Fund’s net assets will rise by approximately twice the amount as the Fund’s exposure. Conversely, if the share price of the Underlying Security declines, the Fund’s net assets will decline by approximately two times the amount as the Fund’s exposure. Thus, an investor that purchases Shares intra-day may experience performance that is greater than, or less than, the Fund’s stated leveraged performance of the Underlying Security.
If there is a significant intra-day market event and/or the securities of the Underlying Security experience a significant increase or decrease, the Fund may not meet its investment objective or rebalance its portfolio appropriately.

| Prospectus [Line Items] | |||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||
| Risk [Text Block] | Fixed Income Securities Risk. When the Fund invests in fixed income securities, the value of your investment in the Fund will fluctuate with changes in interest rates. Typically, a rise in interest rates causes a decline in the value of fixed income securities owned by the Fund. In general, the market price of fixed income securities with longer maturities will increase or decrease more in response to changes in interest rates than shorter-term securities. Other risk factors include credit risk (the debtor may default), extension risk (an issuer may exercise its right to repay principal on a fixed rate obligation held by the Fund later than expected), and prepayment risk (the debtor may pay its obligation early, reducing the amount of interest payments). These risks could affect the value of a particular investment by the Fund, possibly causing the Fund’s Share price and total return to be reduced and fluctuate more than other types of investments.

| Risk [Text Block] | Rebalancing Risk. If for any reason the Fund is unable to rebalance all or a portion of its portfolio, or if all or a portion of the portfolio is rebalanced incorrectly, the Fund’s investment exposure may not be consistent with the Fund’s investment objective. In these instances, the Fund may have investment exposure to the Underlying Security that is significantly greater or less than its stated investment objective. As a result, the Fund may be exposed to leverage risk because it had not been properly rebalanced and may not achieve its investment objective.

| Risk [Text Block] | 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] | 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. The costs associated with cash redemptions may include brokerage costs that the Fund may not have incurred if it had made the redemptions in-kind. These costs could be imposed on the Fund, decreasing its NAV, to the extent these costs are not offset by a transaction fee payable by an authorized participant.

| Risk [Text Block] | Trading. Although Shares are listed on a national securities exchange, such as Cboe BZX Exchange, Inc. (the “Exchange”), and may be traded on U.S. exchanges other than the Exchange, there can be no assurance that Shares will trade with any volume, or at all, on any stock exchange. 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. This adverse effect on liquidity for the Fund’s shares may lead to wider bid-ask spreads and differences between the market price of the Fund’s shares and the underlying value of the shares.

| Risk [Text Block] | Liquidity Risk. In certain circumstances, such as the disruption of the orderly markets for the financial instruments in which the Fund invests, the Fund might not be able to acquire or dispose of certain holdings quickly or at prices that represent true market value in the judgment of the Adviser. Markets for the financial instruments in which the Fund invests may be disrupted by a number of events, including but not limited to economic crises, health crises, natural disasters, excessive volatility, new legislation, or regulatory changes inside or outside of the U.S. These situations may have an impact on the liquidity of the Fund’s own shares.”

| Risk [Text Block] | Economic and Market Risk. Economies and financial markets throughout the world are becoming increasingly interconnected, which increases the likelihood that events or conditions in one country or region will adversely impact markets or issuers in other countries or regions. Securities in the Fund’s portfolio may underperform in comparison to securities in the general financial markets, a particular financial market, or other asset classes, due to a number of factors, including inflation (or expectations for inflation), deflation (or expectations for deflation), interest rates, global demand for particular products or resources, market instability, financial system instability, debt crises and downgrades, embargoes, tariffs, sanctions and other trade barriers, regulatory events, other governmental trade or market control programs and related geopolitical events. In addition, the value of the Fund’s investments may be negatively affected by the occurrence of global events such as war, terrorism, environmental disasters, natural disasters or events, country instability, and infectious disease epidemics or pandemics. The imposition by the U.S. of tariffs on goods imported from foreign countries and reciprocal tariffs levied on U.S. goods by those countries also may lead to volatility and instability in domestic and foreign markets.

| Prospectus [Line Items] | |||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||
| Risk [Text Block] | High Portfolio Turnover Risk. Daily rebalancing of the Fund’s holdings pursuant to its daily investment objective causes a much greater number of portfolio transactions when compared to most ETFs. Additionally, active market trading of the Fund’s Shares on exchanges (such as the Exchange), could cause more frequent creation and redemption activities, which could increase the number of portfolio transactions. Frequent and active trading may lead to higher transaction costs because of increased broker commissions resulting from such transactions. In addition, there is the possibility of significantly increased short-term capital gains (which will be taxable to shareholders as ordinary income when distributed to them). The Fund calculates portfolio turnover without including the short-term cash instruments or derivative transactions that comprise the majority of the Fund’s trading. As such, if the Fund’s extensive use of derivative instruments were reflected, the calculated portfolio turnover rate would be significantly higher.

| Risk [Text Block] | Tracking Error Risk. Tracking error is the divergence of the Fund’s performance from that of its investment objective which aims to replicate two times the daily percentage change in the price of the Underlying Security. Tracking error may occur for a number of reasons. Tracking error may occur because of transaction costs, the Fund’s holding of cash, differences in accrual of dividends, being under- or overexposed to the Underlying Security or the need to meet new or existing regulatory requirements. Tracking error risk may be heightened during times of market volatility or other unusual market conditions such as market disruptions. The Fund may be required to deviate from its investment objectives, and therefore experience tracking error, as a result of market restrictions or other legal reasons, including regulatory limits or other restrictions on securities that may be purchased by the Adviser and its affiliates.

| Risk [Text Block] | Liquidity Risk. Some securities held by the Fund may be difficult to sell or be illiquid, particularly during times of market turmoil. 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 may prevent the Fund from limiting losses, realizing gains or achieving a high correlation with the Underlying Security. 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] | Trading Halt Risk. Although the Underlying Security’s shares are listed for trading on an exchange, there can be no assurance that an active trading market for such shares will be available at all times and the Exchange may halt trading of such shares in certain circumstances. A halt in trading in the Underlying Security’s shares is expected, in turn, to result in a halt in the trading in the Fund’s Shares. Trading in the Underlying Security’s and/or Fund’s Shares on the Exchange may be halted due to market conditions or for reasons that, in the view of the Exchange, make trading in the Underlying Security’s and/or Fund’s Shares inadvisable. In addition, trading in Underlying Security’s and/or Fund’s Shares on an exchange is subject to trading halts caused by extraordinary market volatility pursuant to exchange “circuit breaker” rules.” In the event of a trading halt for an extended period of time, the Fund may be unable to execute arrangements with swap counterparties that are necessary to implement the Fund’s investment strategy.

| Risk [Text Block] | Tax Risk. The Fund intends to elect and to qualify each year to be treated as a regulated investment company (a “RIC”) under Subchapter M of the Internal Revenue Code of 1986, as amended (“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 swap contracts and options on shares of a single issuer does not exceed 25% of the Fund’s value at the close of any quarter. If the value of swap contracts and options on shares of a single issuer 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] | 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] | Compounding and Market Volatility Risk. The Fund has a daily leveraged investment objective and the Fund’s performance for periods greater than a trading day will be the result of each day’s returns compounded over the period, which is very likely to differ from two times (200%) the Underlying Security’s performance, before the Fund’s management fee and other expenses. Compounding affects all investments but has a more significant impact on funds that aim to replicate leveraged daily returns and that rebalance daily. For the Fund aiming to replicate two times the daily performance of an Underlying Security, if adverse daily performance of the Underlying Security reduces the amount of a shareholder’s investment, any further adverse daily performance will lead to a smaller dollar loss because the shareholder’s investment had already been reduced by the prior adverse performance. Equally, however, if favorable daily performance of the Underlying Security increases the amount of a shareholder’s investment, the dollar amount lost due to future adverse performance will increase because the shareholder’s investment has increased.
The effect of compounding becomes more pronounced as the Underlying Security’s volatility and the holding period increase. The impact of compounding will impact each shareholder differently depending on the period of time an investment in the Fund is held and the volatility of the Underlying Security during a shareholder’s holding period of an investment in the Fund.
The chart below provides examples of how the Underlying Security’s volatility could affect the Fund’s performance. The chart illustrates the impact of two factors that affect the Fund’s performance – the Underlying Security’s volatility and the Underlying Security’s performance. The Underlying Security’s performance shows the percentage change in the share price of the Underlying Security over the specified time period, while the Underlying Security’s volatility is a statistical measure of the magnitude of fluctuations in the returns during that time period. As illustrated below, even if the Underlying Security’s performance over two equal time periods is identical, different Underlying Security volatility (i.e., in magnitude of fluctuations in the share price of the Underlying Security) during the two time periods could result in drastically different Fund performance for the two time periods because of compounding daily returns during the time periods.
Fund performance for periods greater than one single day can be estimated given any set of assumptions for the following factors: a) the Underlying Security volatility; b) the Underlying Security performance; c) period of time; d) financing rates associated with leveraged exposure; and e) other Fund expenses. The chart shows estimated Fund returns for a number of combinations of Underlying Security volatility and Underlying Security performance over a one-year period. Performance shown in the chart assumes that: (i) there were no Fund expenses; (ii) borrowing/lending rates (to obtain leveraged exposure) of 0%. If Fund expenses and/or actual borrowing/lending rates were reflected the estimated returns would be different than those shown. Particularly during periods of higher Underlying Security volatility, compounding will cause results for periods longer than a trading day to vary from two times (200%) the performance of the Underlying Security.
As shown in the chart below, the Fund would be expected to lose 6.1% if there was no change in the share price of the Underlying Security over a one-year period during which the Underlying Security experienced annualized volatility of 25%. If the Underlying Security’s annualized volatility were to rise to 75%, the hypothetical loss for a one-year period would widen to approximately -43%. At higher ranges of volatility, there is a chance of a significant loss of value in the Fund, even if there were no change in the share price of the Underlying Security. For instance, if the Underlying Security’s annualized volatility is 100%, the Fund would be expected to lose 63.2% of its value, even if the cumulative Underlying Security change in the share price of the Underlying Security for the year was 0%.
Areas shaded red (or dark gray) represent those scenarios where the Fund can be expected to return less than two times (200%) the performance of the Underlying Security and those shaded green (or light gray) represent those scenarios where the Fund can be expected to return more than two times (200%) the performance of the Underlying Security. The Fund’s actual performance may be significantly better or worse than the performance shown below as a result of any of the factors discussed above or in the “Daily Correlation/Tracking Risk” below.
The Underlying Security’s five-year annualized historical volatility rate for the period ended March 6, 2026, was 64.02%. The Underlying Security’s annualized performance during this period was 39.36%. Historical Underlying Security volatility and performance are not indications of what Underlying Security volatility and performance will be in the future.

| Risk [Text Block] | Daily Correlation/Tracking Risk. There is no guarantee that the Fund will achieve a high degree of leveraged correlation to the Underlying Security and therefore achieve its daily leveraged investment objective. To achieve a high degree of leveraged correlation with the Underlying Security, the Fund seeks to rebalance its portfolio daily to keep exposure consistent with its daily leveraged investment objective. The possibility of the Fund being materially over- or under-exposed to the Underlying Security increases on days when the Underlying Security is volatile near the close of the trading day. Market disruptions, regulatory restrictions and extreme volatility will also adversely affect the Fund’s ability to adjust exposure to the required levels. If there is a significant intra-day market event and/or the Underlying Security experiences a significant increase or decline, the Fund may not meet its investment objective, be able to rebalance its portfolio appropriately, or may experience significant premiums or discounts, or widened bid-ask spreads.
The Fund may have difficulty achieving its daily leveraged investment objective due to fees, expenses, transaction costs, financing costs related to the use of derivatives, investments in ETFs, directly or indirectly, income items, valuation methodology, accounting standards and disruptions or illiquidity in the markets for the securities or derivatives held by the Fund. The Fund may be subject to large movements of assets into and out of the Fund, potentially resulting in the Fund being over- or under-exposed to the Underlying Security. The Fund may take or refrain from taking positions to improve the tax efficiency or to comply with various regulatory restrictions, either of which may negatively impact the Fund’s leveraged correlation to the Underlying Security.

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

| Risk [Text Block] | 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, leverage, imperfect daily correlations with underlying investments or the Fund’s other portfolio holdings, 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 imperfect correlation between the share price of the Underlying Security 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.
The Fund will be subject to regulatory constraints relating to level of value at risk that the Fund may incur through its derivative portfolio. To the extent the Fund exceeds these regulatory thresholds over an extended period, the Fund may determine that it is necessary to make adjustments to the Fund’s investment strategy, including the desired daily leveraged performance for the Fund.
In addition, the Fund’s investments in derivatives are subject to the following risks:

| Prospectus [Line Items] | |||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||
| Risk [Text Block] | Swap Agreements. The use of swap transactions is a highly specialized activity, which involves investment techniques and risks different from those associated with ordinary portfolio securities transactions. Whether the Fund will be successful in using swap agreements to achieve its investment goal depends on the ability of the Adviser to structure such swap agreements in accordance with the Fund’s investment objective and to identify counterparties for those swap agreements. If the Adviser is unable to enter into swap agreements that provide leveraged exposure to the Underlying Security, the Fund may not meet its stated investment objective. Additionally, any financing, borrowing or other costs associated with using swap transactions may also have the effect of lowering the Fund’s return.
The swap agreements in which the Fund invests are generally traded in the over-the-counter market, which generally has less transparency than exchange-traded derivatives instruments. In a standard swap transaction, two parties agree to exchange the return (or differentials in rates of return) earned or realized on particular predetermined reference assets or underlying securities or instruments. The gross return to be exchanged or swapped between the parties is calculated based on a notional amount or the return on or change in value of a particular dollar amount invested in a basket of securities.
If the Underlying Security has a dramatic move that causes a material decline in the Fund’s net assets, the terms of a swap agreement between the Fund and its counterparty may permit the counterparty to immediately close out the swap transaction with the Fund. In that event, the Fund may be unable to enter into another swap agreement or invest in other derivatives to achieve exposure consistent with the Fund’s investment objective. This may prevent the Fund from achieving its leveraged investment objective, even if the Underlying Security later reverses all or a portion of its movement.

| Prospectus [Line Items] | |||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||
| Risk [Text Block] | 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. The value of the options contracts in which the Fund invests are substantially influenced by the value of the Underlying Security. 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 as 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, as the Fund intends to continuously maintain indirect exposure to the Underlying Security through the use of options contracts, as the options contracts it holds are exercised or expire it will enter into new options contracts, a practice referred to as “rolling.” If the expiring options contracts do not generate proceeds enough to cover the cost of entering into new options contracts, the Fund may experience losses. The use of options to generate leverage introduces additional risks, including significant potential losses if the market moves unfavorably. The leverage inherent in options can amplify both gains and losses, leading to increased volatility and potential for substantial losses, particularly in periods of market uncertainty or low liquidity. Additionally, the Fund may incur losses if the value of the Underlying Security moves against its positions, potentially resulting in a complete loss of the premium paid.

| Prospectus [Line Items] | |||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||
| Risk [Text Block] | Counterparty Risk. The Fund is subject to counterparty risk by virtue of its investments in derivatives which exposes the Fund to the risk that the counterparty will not fulfill its obligation to the Fund. Counterparty risk may arise because of the counterparty’s financial condition (i.e., financial difficulties, bankruptcy, or insolvency), market activities and developments, or other reasons, whether foreseen or not. A counterparty’s inability to fulfill its obligation may result in significant financial loss to the Fund and the Fund may be unable to recover its investment from such counterparty or may obtain a limited and/or delayed recovery.
Counterparties may seek to hedge their exposure to individual clients (such as the Fund) by establishing offsetting exposures with other clients, however, there is no guarantee that counterparties will do so under all circumstances. Should a counterparty (e.g., a swap counterparty) terminate its relationship with the Fund, the Fund will seek to utilize other counterparties to seek to maintain its exposures. In addition, the Fund may use options contracts to seek to generate the leverage necessary to implement its strategy. The use of options contracts introduces distinct risks, including heightened volatility, particularly intraday. While options may provide an ancillary benefit of mitigating some losses under specific scenarios, such as severe market downturns, their inherent leverage and rapid price fluctuations can amplify the Fund’s performance volatility and lead to greater risks of substantial losses. Refer to “Derivatives Risk – Options Contracts” for additional information on the risks of investing in options.
In addition, the Fund may enter into swap agreements with a limited number of counterparties, which may increase the Fund’s exposure to counterparty credit risk. Further, there is a risk that no suitable counterparties will be willing to enter into, or continue to enter into, transactions with the Fund and, as a result, the Fund may not be able to achieve its investment objective.

| Prospectus [Line Items] | |||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||
| Risk [Text Block] | Intra-Day Investment Risk. The Fund seeks investment results from the close of the market on a given trading day until the close of the market on the subsequent trading day. The exact exposure of an investment in the Fund intraday in the secondary market is a function of the difference between the share price of the Underlying Security at the market close on the first trading day and the share price of the Underlying Security at the time of purchase. If the share price of the Underlying Security rises, the Fund’s net assets will rise by approximately twice the amount as the Fund’s exposure. Conversely, if the share price of the Underlying Security declines, the Fund’s net assets will decline by approximately two times the amount as the Fund’s exposure. Thus, an investor that purchases Shares intra-day may experience performance that is greater than, or less than, the Fund’s stated leveraged performance of the Underlying Security.
If there is a significant intra-day market event and/or the securities of the Underlying Security experience a significant increase or decrease, the Fund may not meet its investment objective or rebalance its portfolio appropriately.

| Risk [Text Block] | Fixed Income Securities Risk. When the Fund invests in fixed income securities, the value of your investment in the Fund will fluctuate with changes in interest rates. Typically, a rise in interest rates causes a decline in the value of fixed income securities owned by the Fund. In general, the market price of fixed income securities with longer maturities will increase or decrease more in response to changes in interest rates than shorter-term securities. Other risk factors include credit risk (the debtor may default), extension risk (an issuer may exercise its right to repay principal on a fixed rate obligation held by the Fund later than expected), and prepayment risk (the debtor may pay its obligation early, reducing the amount of interest payments). These risks could affect the value of a particular investment by the Fund, possibly causing the Fund’s Share price and total return to be reduced and fluctuate more than other types of investments.

| Risk [Text Block] | Rebalancing Risk. If for any reason the Fund is unable to rebalance all or a portion of its portfolio, or if all or a portion of the portfolio is rebalanced incorrectly, the Fund’s investment exposure may not be consistent with the Fund’s investment objective. In these instances, the Fund may have investment exposure to the Underlying Security that is significantly greater or less than its stated investment objective. As a result, the Fund may be exposed to leverage risk because it had not been properly rebalanced and may not achieve its investment objective.

| Risk [Text Block] | 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] | 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. The costs associated with cash redemptions may include brokerage costs that the Fund may not have incurred if it had made the redemptions in-kind. These costs could be imposed on the Fund, decreasing its NAV, to the extent these costs are not offset by a transaction fee payable by an authorized participant.

| Risk [Text Block] | Trading. Although Shares are listed on a national securities exchange, such as Cboe BZX Exchange, Inc. (the “Exchange”), and may be traded on U.S. exchanges other than the Exchange, there can be no assurance that Shares will trade with any volume, or at all, on any stock exchange. 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. This adverse effect on liquidity for the Fund’s shares may lead to wider bid-ask spreads and differences between the market price of the Fund’s shares and the underlying value of the shares.

In certain circumstances, such as the disruption of the orderly markets for the financial instruments in which the Fund invests, the Fund might not be able to acquire or dispose of certain holdings quickly or at prices that represent true market value in the judgment of the Adviser. Markets for the financial instruments in which the Fund invests may be disrupted by a number of events, including but not limited to economic crises, health crises, natural disasters, excessive volatility, new legislation, or regulatory changes inside or outside of the U.S. These situations may have an impact on the liquidity of the Fund’s own shares.”

| Risk [Text Block] | Economic and Market Risk. Economies and financial markets throughout the world are becoming increasingly interconnected, which increases the likelihood that events or conditions in one country or region will adversely impact markets or issuers in other countries or regions. Securities in the Fund’s portfolio may underperform in comparison to securities in the general financial markets, a particular financial market, or other asset classes, due to a number of factors, including inflation (or expectations for inflation), deflation (or expectations for deflation), interest rates, global demand for particular products or resources, market instability, financial system instability, debt crises and downgrades, embargoes, tariffs, sanctions and other trade barriers, regulatory events, other governmental trade or market control programs and related geopolitical events. In addition, the value of the Fund’s investments may be negatively affected by the occurrence of global events such as war, terrorism, environmental disasters, natural disasters or events, country instability, and infectious disease epidemics or pandemics. The imposition by the U.S. of tariffs on goods imported from foreign countries and reciprocal tariffs levied on U.S. goods by those countries also may lead to volatility and instability in domestic and foreign markets.

| Risk [Text Block] | High Portfolio Turnover Risk. Daily rebalancing of the Fund’s holdings pursuant to its daily investment objective causes a much greater number of portfolio transactions when compared to most ETFs. Additionally, active market trading of the Fund’s Shares on exchanges (such as the Exchange), could cause more frequent creation and redemption activities, which could increase the number of portfolio transactions. Frequent and active trading may lead to higher transaction costs because of increased broker commissions resulting from such transactions. In addition, there is the possibility of significantly increased short-term capital gains (which will be taxable to shareholders as ordinary income when distributed to them). The Fund calculates portfolio turnover without including the short-term cash instruments or derivative transactions that comprise the majority of the Fund’s trading. As such, if the Fund’s extensive use of derivative instruments were reflected, the calculated portfolio turnover rate would be significantly higher.

| Risk [Text Block] | Tracking Error Risk. Tracking error is the divergence of the Fund’s performance from that of its investment objective which aims to replicate two times the daily percentage change in the price of the Underlying Security. Tracking error may occur for a number of reasons. Tracking error may occur because of transaction costs, the Fund’s holding of cash, differences in accrual of dividends, being under- or overexposed to the Underlying Security or the need to meet new or existing regulatory requirements. Tracking error risk may be heightened during times of market volatility or other unusual market conditions such as market disruptions. The Fund may be required to deviate from its investment objectives, and therefore experience tracking error, as a result of market restrictions or other legal reasons, including regulatory limits or other restrictions on securities that may be purchased by the Adviser and its affiliates.

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 may prevent the Fund from limiting losses, realizing gains or achieving a high correlation with the Underlying Security. 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.

Although the Underlying Security’s shares are listed for trading on an exchange, there can be no assurance that an active trading market for such shares will be available at all times and the Exchange may halt trading of such shares in certain circumstances. A halt in trading in the Underlying Security’s shares is expected, in turn, to result in a halt in the trading in the Fund’s Shares. Trading in the Underlying Security’s and/or Fund’s Shares on the Exchange may be halted due to market conditions or for reasons that, in the view of the Exchange, make trading in the Underlying Security’s and/or Fund’s Shares inadvisable. In addition, trading in Underlying Security’s and/or Fund’s Shares on an exchange is subject to trading halts caused by extraordinary market volatility pursuant to exchange “circuit breaker” rules.” In the event of a trading halt for an extended period of time, the Fund may be unable to execute arrangements with swap counterparties that are necessary to implement the Fund’s investment strategy.

| Risk [Text Block] | 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.

| Risk [Text Block] | Tax Risk. The Fund intends to elect and to qualify each year to be treated as a regulated investment company (a “RIC”) under Subchapter M of the Internal Revenue Code of 1986, as amended (“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 swap contracts and options on shares of a single issuer does not exceed 25% of the Fund’s value at the close of any quarter. If the value of swap contracts and options on shares of a single issuer 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] | 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] | Single Issuer Risk. Issuer-specific attributes may cause an investment in the Fund to be more volatile than a traditional pooled investment which diversifies risk or the market generally. The value of the Fund, which focuses on an individual security, 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. Additionally, the Fund will seek to employ its investment strategy as it relates to the underlying issuer regardless of whether there are significant corporate actions such as restructurings, enforcement activity, or acquisitions or periods adverse market, economic, or other conditions and will not seek to take temporary defensive positions during such periods.

| Prospectus [Line Items] | |||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||
| Risk [Text Block] | Compounding and Market Volatility Risk. The Fund has a daily leveraged investment objective and the Fund’s performance for periods greater than a trading day will be the result of each day’s returns compounded over the period, which is very likely to differ from two times (200%) the Underlying Security’s performance, before the Fund’s management fee and other expenses. Compounding affects all investments but has a more significant impact on funds that aim to replicate leveraged daily returns and that rebalance daily. For the Fund aiming to replicate two times the daily performance of an Underlying Security, if adverse daily performance of the Underlying Security reduces the amount of a shareholder’s investment, any further adverse daily performance will lead to a smaller dollar loss because the shareholder’s investment had already been reduced by the prior adverse performance. Equally, however, if favorable daily performance of the Underlying Security increases the amount of a shareholder’s investment, the dollar amount lost due to future adverse performance will increase because the shareholder’s investment has increased.
The effect of compounding becomes more pronounced as the Underlying Security’s volatility and the holding period increase. The impact of compounding will impact each shareholder differently depending on the period of time an investment in the Fund is held and the volatility of the Underlying Security during a shareholder’s holding period of an investment in the Fund.
The chart below provides examples of how the Underlying Security’s volatility could affect the Fund’s performance. The chart illustrates the impact of two factors that affect the Fund’s performance – the Underlying Security’s volatility and the Underlying Security’s performance. The Underlying Security’s performance shows the percentage change in the share price of the Underlying Security over the specified time period, while the Underlying Security’s volatility is a statistical measure of the magnitude of fluctuations in the returns during that time period. As illustrated below, even if the Underlying Security’s performance over two equal time periods is identical, different Underlying Security volatility (i.e., in magnitude of fluctuations in the share price of the Underlying Security) during the two time periods could result in drastically different Fund performance for the two time periods because of compounding daily returns during the time periods.
Fund performance for periods greater than one single day can be estimated given any set of assumptions for the following factors: a) the Underlying Security volatility; b) the Underlying Security performance; c) period of time; d) financing rates associated with leveraged exposure; and e) other Fund expenses. The chart shows estimated Fund returns for a number of combinations of Underlying Security volatility and Underlying Security performance over a one-year period. Performance shown in the chart assumes that: (i) there were no Fund expenses; (ii) borrowing/lending rates (to obtain leveraged exposure) of 0%. If Fund expenses and/or actual borrowing/lending rates were reflected the estimated returns would be different than those shown. Particularly during periods of higher Underlying Security volatility, compounding will cause results for periods longer than a trading day to vary from two times (200%) the performance of the Underlying Security.
As shown in the chart below, the Fund would be expected to lose 6.1% if there was no change in the share price of the Underlying Security over a one-year period during which the Underlying Security experienced annualized volatility of 25%. If the Underlying Security’s annualized volatility were to rise to 75%, the hypothetical loss for a one-year period would widen to approximately -43%. At higher ranges of volatility, there is a chance of a significant loss of value in the Fund, even if there were no change in the share price of the Underlying Security. For instance, if the Underlying Security’s annualized volatility is 100%, the Fund would be expected to lose 63.2% of its value, even if the cumulative Underlying Security change in the share price of the Underlying Security for the year was 0%.
Areas shaded red (or dark gray) represent those scenarios where the Fund can be expected to return less than two times (200%) the performance of the Underlying Security and those shaded green (or light gray) represent those scenarios where the Fund can be expected to return more than two times (200%) the performance of the Underlying Security. The Fund’s actual performance may be significantly better or worse than the performance shown below as a result of any of the factors discussed above or in the “Daily Correlation/Tracking Risk” below.
The Underlying Security’s five-year annualized historical volatility rate for the period ended March 6, 2026, was 73.07%. The Underlying Security’s annualized performance during this period was -33.80%. Historical Underlying Security volatility and performance are not indications of what Underlying Security volatility and performance will be in the future.

| Risk [Text Block] | Daily Correlation/Tracking Risk. There is no guarantee that the Fund will achieve a high degree of leveraged correlation to the Underlying Security and therefore achieve its daily leveraged investment objective. To achieve a high degree of leveraged correlation with the Underlying Security, the Fund seeks to rebalance its portfolio daily to keep exposure consistent with its daily leveraged investment objective. The possibility of the Fund being materially over- or under-exposed to the Underlying Security increases on days when the Underlying Security is volatile near the close of the trading day. Market disruptions, regulatory restrictions and extreme volatility will also adversely affect the Fund’s ability to adjust exposure to the required levels. If there is a significant intra-day market event and/or the Underlying Security experiences a significant increase or decline, the Fund may not meet its investment objective, be able to rebalance its portfolio appropriately, or may experience significant premiums or discounts, or widened bid-ask spreads.
The Fund may have difficulty achieving its daily leveraged investment objective due to fees, expenses, transaction costs, financing costs related to the use of derivatives, investments in ETFs, directly or indirectly, income items, valuation methodology, accounting standards and disruptions or illiquidity in the markets for the securities or derivatives held by the Fund. The Fund may be subject to large movements of assets into and out of the Fund, potentially resulting in the Fund being over- or under-exposed to the Underlying Security. The Fund may take or refrain from taking positions to improve the tax efficiency or to comply with various regulatory restrictions, either of which may negatively impact the Fund’s leveraged correlation to the Underlying Security.

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

| Risk [Text Block] | 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, leverage, imperfect daily correlations with underlying investments or the Fund’s other portfolio holdings, 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 imperfect correlation between the share price of the Underlying Security 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.
The Fund will be subject to regulatory constraints relating to level of value at risk that the Fund may incur through its derivative portfolio. To the extent the Fund exceeds these regulatory thresholds over an extended period, the Fund may determine that it is necessary to make adjustments to the Fund’s investment strategy, including the desired daily leveraged performance for the Fund.
In addition, the Fund’s investments in derivatives are subject to the following risks:

| Risk [Text Block] | Swap Agreements. The use of swap transactions is a highly specialized activity, which involves investment techniques and risks different from those associated with ordinary portfolio securities transactions. Whether the Fund will be successful in using swap agreements to achieve its investment goal depends on the ability of the Adviser to structure such swap agreements in accordance with the Fund’s investment objective and to identify counterparties for those swap agreements. If the Adviser is unable to enter into swap agreements that provide leveraged exposure to the Underlying Security, the Fund may not meet its stated investment objective. Additionally, any financing, borrowing or other costs associated with using swap transactions may also have the effect of lowering the Fund’s return.
The swap agreements in which the Fund invests are generally traded in the over-the-counter market, which generally has less transparency than exchange-traded derivatives instruments. In a standard swap transaction, two parties agree to exchange the return (or differentials in rates of return) earned or realized on particular predetermined reference assets or underlying securities or instruments. The gross return to be exchanged or swapped between the parties is calculated based on a notional amount or the return on or change in value of a particular dollar amount invested in a basket of securities.
If the Underlying Security has a dramatic move that causes a material decline in the Fund’s net assets, the terms of a swap agreement between the Fund and its counterparty may permit the counterparty to immediately close out the swap transaction with the Fund. In that event, the Fund may be unable to enter into another swap agreement or invest in other derivatives to achieve exposure consistent with the Fund’s investment objective. This may prevent the Fund from achieving its leveraged investment objective, even if the Underlying Security later reverses all or a portion of its movement.

| Risk [Text Block] | 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. The value of the options contracts in which the Fund invests are substantially influenced by the value of the Underlying Security. 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 as 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, as the Fund intends to continuously maintain indirect exposure to the Underlying Security through the use of options contracts, as the options contracts it holds are exercised or expire it will enter into new options contracts, a practice referred to as “rolling.” If the expiring options contracts do not generate proceeds enough to cover the cost of entering into new options contracts, the Fund may experience losses. The use of options to generate leverage introduces additional risks, including significant potential losses if the market moves unfavorably. The leverage inherent in options can amplify both gains and losses, leading to increased volatility and potential for substantial losses, particularly in periods of market uncertainty or low liquidity. Additionally, the Fund may incur losses if the value of the Underlying Security moves against its positions, potentially resulting in a complete loss of the premium paid.

| Prospectus [Line Items] | |||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||
| Risk [Text Block] | Counterparty Risk. The Fund is subject to counterparty risk by virtue of its investments in derivatives which exposes the Fund to the risk that the counterparty will not fulfill its obligation to the Fund. Counterparty risk may arise because of the counterparty’s financial condition (i.e., financial difficulties, bankruptcy, or insolvency), market activities and developments, or other reasons, whether foreseen or not. A counterparty’s inability to fulfill its obligation may result in significant financial loss to the Fund and the Fund may be unable to recover its investment from such counterparty or may obtain a limited and/or delayed recovery.
Counterparties may seek to hedge their exposure to individual clients (such as the Fund) by establishing offsetting exposures with other clients, however, there is no guarantee that counterparties will do so under all circumstances. Should a counterparty (e.g., a swap counterparty) terminate its relationship with the Fund, the Fund will seek to utilize other counterparties to seek to maintain its exposures. In addition, the Fund may use options contracts to seek to generate the leverage necessary to implement its strategy. The use of options contracts introduces distinct risks, including heightened volatility, particularly intraday. While options may provide an ancillary benefit of mitigating some losses under specific scenarios, such as severe market downturns, their inherent leverage and rapid price fluctuations can amplify the Fund’s performance volatility and lead to greater risks of substantial losses. Refer to “Derivatives Risk – Options Contracts” for additional information on the risks of investing in options.
In addition, the Fund may enter into swap agreements with a limited number of counterparties, which may increase the Fund’s exposure to counterparty credit risk. Further, there is a risk that no suitable counterparties will be willing to enter into, or continue to enter into, transactions with the Fund and, as a result, the Fund may not be able to achieve its investment objective.

| Prospectus [Line Items] | |||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||
| Risk [Text Block] | Intra-Day Investment Risk. The Fund seeks investment results from the close of the market on a given trading day until the close of the market on the subsequent trading day. The exact exposure of an investment in the Fund intraday in the secondary market is a function of the difference between the share price of the Underlying Security at the market close on the first trading day and the share price of the Underlying Security at the time of purchase. If the share price of the Underlying Security rises, the Fund’s net assets will rise by approximately twice the amount as the Fund’s exposure. Conversely, if the share price of the Underlying Security declines, the Fund’s net assets will decline by approximately two times the amount as the Fund’s exposure. Thus, an investor that purchases Shares intra-day may experience performance that is greater than, or less than, the Fund’s stated leveraged performance of the Underlying Security.
If there is a significant intra-day market event and/or the securities of the Underlying Security experience a significant increase or decrease, the Fund may not meet its investment objective or rebalance its portfolio appropriately.

| Risk [Text Block] | Fixed Income Securities Risk. When the Fund invests in fixed income securities, the value of your investment in the Fund will fluctuate with changes in interest rates. Typically, a rise in interest rates causes a decline in the value of fixed income securities owned by the Fund. In general, the market price of fixed income securities with longer maturities will increase or decrease more in response to changes in interest rates than shorter-term securities. Other risk factors include credit risk (the debtor may default), extension risk (an issuer may exercise its right to repay principal on a fixed rate obligation held by the Fund later than expected), and prepayment risk (the debtor may pay its obligation early, reducing the amount of interest payments). These risks could affect the value of a particular investment by the Fund, possibly causing the Fund’s Share price and total return to be reduced and fluctuate more than other types of investments.

If for any reason the Fund is unable to rebalance all or a portion of its portfolio, or if all or a portion of the portfolio is rebalanced incorrectly, the Fund’s investment exposure may not be consistent with the Fund’s investment objective. In these instances, the Fund may have investment exposure to the Underlying Security that is significantly greater or less than its stated investment objective. As a result, the Fund may be exposed to leverage risk because it had not been properly rebalanced and may not achieve its investment objective.

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] | 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. The costs associated with cash redemptions may include brokerage costs that the Fund may not have incurred if it had made the redemptions in-kind. These costs could be imposed on the Fund, decreasing its NAV, to the extent these costs are not offset by a transaction fee payable by an authorized participant.

| Risk [Text Block] | Trading. Although Shares are listed on a national securities exchange, such as Cboe BZX Exchange, Inc. (the “Exchange”), and may be traded on U.S. exchanges other than the Exchange, there can be no assurance that Shares will trade with any volume, or at all, on any stock exchange. 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. This adverse effect on liquidity for the Fund’s shares may lead to wider bid-ask spreads and differences between the market price of the Fund’s shares and the underlying value of the shares.

In certain circumstances, such as the disruption of the orderly markets for the financial instruments in which the Fund invests, the Fund might not be able to acquire or dispose of certain holdings quickly or at prices that represent true market value in the judgment of the Adviser. Markets for the financial instruments in which the Fund invests may be disrupted by a number of events, including but not limited to economic crises, health crises, natural disasters, excessive volatility, new legislation, or regulatory changes inside or outside of the U.S. These situations may have an impact on the liquidity of the Fund’s own shares.”

| Risk [Text Block] | Economic and Market Risk. Economies and financial markets throughout the world are becoming increasingly interconnected, which increases the likelihood that events or conditions in one country or region will adversely impact markets or issuers in other countries or regions. Securities in the Fund’s portfolio may underperform in comparison to securities in the general financial markets, a particular financial market, or other asset classes, due to a number of factors, including inflation (or expectations for inflation), deflation (or expectations for deflation), interest rates, global demand for particular products or resources, market instability, financial system instability, debt crises and downgrades, embargoes, tariffs, sanctions and other trade barriers, regulatory events, other governmental trade or market control programs and related geopolitical events. In addition, the value of the Fund’s investments may be negatively affected by the occurrence of global events such as war, terrorism, environmental disasters, natural disasters or events, country instability, and infectious disease epidemics or pandemics. The imposition by the U.S. of tariffs on goods imported from foreign countries and reciprocal tariffs levied on U.S. goods by those countries also may lead to volatility and instability in domestic and foreign markets.

| Risk [Text Block] | High Portfolio Turnover Risk. Daily rebalancing of the Fund’s holdings pursuant to its daily investment objective causes a much greater number of portfolio transactions when compared to most ETFs. Additionally, active market trading of the Fund’s Shares on exchanges (such as the Exchange), could cause more frequent creation and redemption activities, which could increase the number of portfolio transactions. Frequent and active trading may lead to higher transaction costs because of increased broker commissions resulting from such transactions. In addition, there is the possibility of significantly increased short-term capital gains (which will be taxable to shareholders as ordinary income when distributed to them). The Fund calculates portfolio turnover without including the short-term cash instruments or derivative transactions that comprise the majority of the Fund’s trading. As such, if the Fund’s extensive use of derivative instruments were reflected, the calculated portfolio turnover rate would be significantly higher.

| Risk [Text Block] | Tracking Error Risk. Tracking error is the divergence of the Fund’s performance from that of its investment objective which aims to replicate two times the daily percentage change in the price of the Underlying Security. Tracking error may occur for a number of reasons. Tracking error may occur because of transaction costs, the Fund’s holding of cash, differences in accrual of dividends, being under- or overexposed to the Underlying Security or the need to meet new or existing regulatory requirements. Tracking error risk may be heightened during times of market volatility or other unusual market conditions such as market disruptions. The Fund may be required to deviate from its investment objectives, and therefore experience tracking error, as a result of market restrictions or other legal reasons, including regulatory limits or other restrictions on securities that may be purchased by the Adviser and its affiliates.

| Risk [Text Block] | Liquidity Risk. Some securities held by the Fund may be difficult to sell or be illiquid, particularly during times of market turmoil. 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.

Although the Underlying Security’s shares are listed for trading on an exchange, there can be no assurance that an active trading market for such shares will be available at all times and the Exchange may halt trading of such shares in certain circumstances. A halt in trading in the Underlying Security’s shares is expected, in turn, to result in a halt in the trading in the Fund’s Shares. Trading in the Underlying Security’s and/or Fund’s Shares on the Exchange may be halted due to market conditions or for reasons that, in the view of the Exchange, make trading in the Underlying Security’s and/or Fund’s Shares inadvisable. In addition, trading in Underlying Security’s and/or Fund’s Shares on an exchange is subject to trading halts caused by extraordinary market volatility pursuant to exchange “circuit breaker” rules.” In the event of a trading halt for an extended period of time, the Fund may be unable to execute arrangements with swap counterparties that are necessary to implement the Fund’s investment strategy.

| Risk [Text Block] | Tax Risk. The Fund intends to elect and to qualify each year to be treated as a regulated investment company (a “RIC”) under Subchapter M of the Internal Revenue Code of 1986, as amended (“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 swap contracts and options on shares of a single issuer does not exceed 25% of the Fund’s value at the close of any quarter. If the value of swap contracts and options on shares of a single issuer 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] | 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.

The value of the Fund, which focuses on an individual security, 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. Additionally, the Fund will seek to employ its investment strategy as it relates to the underlying issuer regardless of whether there are significant corporate actions such as restructurings, enforcement activity, or acquisitions or periods adverse market, economic, or other conditions and will not seek to take temporary defensive positions during such periods.

| Prospectus [Line Items] | |||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||
| Risk [Text Block] | Compounding and Market Volatility Risk. The Fund has a daily leveraged investment objective and the Fund’s performance for periods greater than a trading day will be the result of each day’s returns compounded over the period, which is very likely to differ from two times (200%) the Underlying Security’s performance, before the Fund’s management fee and other expenses. Compounding affects all investments but has a more significant impact on funds that aim to replicate leveraged daily returns and that rebalance daily. For the Fund aiming to replicate two times the daily performance of an Underlying Security, if adverse daily performance of the Underlying Security reduces the amount of a shareholder’s investment, any further adverse daily performance will lead to a smaller dollar loss because the shareholder’s investment had already been reduced by the prior adverse performance. Equally, however, if favorable daily performance of the Underlying Security increases the amount of a shareholder’s investment, the dollar amount lost due to future adverse performance will increase because the shareholder’s investment has increased.
The effect of compounding becomes more pronounced as the Underlying Security’s volatility and the holding period increase. The impact of compounding will impact each shareholder differently depending on the period of time an investment in the Fund is held and the volatility of the Underlying Security during a shareholder’s holding period of an investment in the Fund.
The chart below provides examples of how the Underlying Security’s volatility could affect the Fund’s performance. The chart illustrates the impact of two factors that affect the Fund’s performance – the Underlying Security’s volatility and the Underlying Security’s performance. The Underlying Security’s performance shows the percentage change in the share price of the Underlying Security over the specified time period, while the Underlying Security’s volatility is a statistical measure of the magnitude of fluctuations in the returns during that time period. As illustrated below, even if the Underlying Security’s performance over two equal time periods is identical, different Underlying Security volatility (i.e., in magnitude of fluctuations in the share price of the Underlying Security) during the two time periods could result in drastically different Fund performance for the two time periods because of compounding daily returns during the time periods.
Fund performance for periods greater than one single day can be estimated given any set of assumptions for the following factors: a) the Underlying Security volatility; b) the Underlying Security performance; c) period of time; d) financing rates associated with leveraged exposure; and e) other Fund expenses. The chart shows estimated Fund returns for a number of combinations of Underlying Security volatility and Underlying Security performance over a one-year period. Performance shown in the chart assumes that: (i) there were no Fund expenses; (ii) borrowing/lending rates (to obtain leveraged exposure) of 0%. If Fund expenses and/or actual borrowing/lending rates were reflected the estimated returns would be different than those shown. Particularly during periods of higher Underlying Security volatility, compounding will cause results for periods longer than a trading day to vary from two times (200%) the performance of the Underlying Security.
As shown in the chart below, the Fund would be expected to lose 6.1% if there was no change in the share price of the Underlying Security over a one-year period during which the Underlying Security experienced annualized volatility of 25%. If the Underlying Security’s annualized volatility were to rise to 75%, the hypothetical loss for a one-year period would widen to approximately -43%. At higher ranges of volatility, there is a chance of a significant loss of value in the Fund, even if there were no change in the share price of the Underlying Security. For instance, if the Underlying Security’s annualized volatility is 100%, the Fund would be expected to lose 63.2% of its value, even if the cumulative Underlying Security change in the share price of the Underlying Security for the year was 0%.
Areas shaded red (or dark gray) represent those scenarios where the Fund can be expected to return less than two times (200%) the performance of the Underlying Security and those shaded green (or light gray) represent those scenarios where the Fund can be expected to return more than two times (200%) the performance of the Underlying Security. The Fund’s actual performance may be significantly better or worse than the performance shown below as a result of any of the factors discussed above or in the “Daily Correlation/Tracking Risk” below.
The Underlying Security’s five-year annualized historical volatility rate for the period ended March 6, 2026, was 91.84%. The Underlying Security’s annualized performance during this period was -49.83%. Historical Underlying Security volatility and performance are not indications of what Underlying Security volatility and performance will be in the future.

| Risk [Text Block] | Daily Correlation/Tracking Risk. There is no guarantee that the Fund will achieve a high degree of leveraged correlation to the Underlying Security and therefore achieve its daily leveraged investment objective. To achieve a high degree of leveraged correlation with the Underlying Security, the Fund seeks to rebalance its portfolio daily to keep exposure consistent with its daily leveraged investment objective. The possibility of the Fund being materially over- or under-exposed to the Underlying Security increases on days when the Underlying Security is volatile near the close of the trading day. Market disruptions, regulatory restrictions and extreme volatility will also adversely affect the Fund’s ability to adjust exposure to the required levels. If there is a significant intra-day market event and/or the Underlying Security experiences a significant increase or decline, the Fund may not meet its investment objective, be able to rebalance its portfolio appropriately, or may experience significant premiums or discounts, or widened bid-ask spreads.
The Fund may have difficulty achieving its daily leveraged investment objective due to fees, expenses, transaction costs, financing costs related to the use of derivatives, investments in ETFs, directly or indirectly, income items, valuation methodology, accounting standards and disruptions or illiquidity in the markets for the securities or derivatives held by the Fund. The Fund may be subject to large movements of assets into and out of the Fund, potentially resulting in the Fund being over- or under-exposed to the Underlying Security. The Fund may take or refrain from taking positions to improve the tax efficiency or to comply with various regulatory restrictions, either of which may negatively impact the Fund’s leveraged correlation to the Underlying Security.

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

| Risk [Text Block] | 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, leverage, imperfect daily correlations with underlying investments or the Fund’s other portfolio holdings, 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 imperfect correlation between the share price of the Underlying Security 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.
The Fund will be subject to regulatory constraints relating to level of value at risk that the Fund may incur through its derivative portfolio. To the extent the Fund exceeds these regulatory thresholds over an extended period, the Fund may determine that it is necessary to make adjustments to the Fund’s investment strategy, including the desired daily leveraged performance for the Fund.
In addition, the Fund’s investments in derivatives are subject to the following risks:

| Risk [Text Block] | Swap Agreements. The use of swap transactions is a highly specialized activity, which involves investment techniques and risks different from those associated with ordinary portfolio securities transactions. Whether the Fund will be successful in using swap agreements to achieve its investment goal depends on the ability of the Adviser to structure such swap agreements in accordance with the Fund’s investment objective and to identify counterparties for those swap agreements. If the Adviser is unable to enter into swap agreements that provide leveraged exposure to the Underlying Security, the Fund may not meet its stated investment objective. Additionally, any financing, borrowing or other costs associated with using swap transactions may also have the effect of lowering the Fund’s return.
The swap agreements in which the Fund invests are generally traded in the over-the-counter market, which generally has less transparency than exchange-traded derivatives instruments. In a standard swap transaction, two parties agree to exchange the return (or differentials in rates of return) earned or realized on particular predetermined reference assets or underlying securities or instruments. The gross return to be exchanged or swapped between the parties is calculated based on a notional amount or the return on or change in value of a particular dollar amount invested in a basket of securities.
If the Underlying Security has a dramatic move that causes a material decline in the Fund’s net assets, the terms of a swap agreement between the Fund and its counterparty may permit the counterparty to immediately close out the swap transaction with the Fund. In that event, the Fund may be unable to enter into another swap agreement or invest in other derivatives to achieve exposure consistent with the Fund’s investment objective. This may prevent the Fund from achieving its leveraged investment objective, even if the Underlying Security later reverses all or a portion of its movement.

| Risk [Text Block] | 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. The value of the options contracts in which the Fund invests are substantially influenced by the value of the Underlying Security. 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 as 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, as the Fund intends to continuously maintain indirect exposure to the Underlying Security through the use of options contracts, as the options contracts it holds are exercised or expire it will enter into new options contracts, a practice referred to as “rolling.” If the expiring options contracts do not generate proceeds enough to cover the cost of entering into new options contracts, the Fund may experience losses. The use of options to generate leverage introduces additional risks, including significant potential losses if the market moves unfavorably. The leverage inherent in options can amplify both gains and losses, leading to increased volatility and potential for substantial losses, particularly in periods of market uncertainty or low liquidity. Additionally, the Fund may incur losses if the value of the Underlying Security moves against its positions, potentially resulting in a complete loss of the premium paid.

| Risk [Text Block] | Counterparty Risk. The Fund is subject to counterparty risk by virtue of its investments in derivatives which exposes the Fund to the risk that the counterparty will not fulfill its obligation to the Fund. Counterparty risk may arise because of the counterparty’s financial condition (i.e., financial difficulties, bankruptcy, or insolvency), market activities and developments, or other reasons, whether foreseen or not. A counterparty’s inability to fulfill its obligation may result in significant financial loss to the Fund and the Fund may be unable to recover its investment from such counterparty or may obtain a limited and/or delayed recovery.
Counterparties may seek to hedge their exposure to individual clients (such as the Fund) by establishing offsetting exposures with other clients, however, there is no guarantee that counterparties will do so under all circumstances. Should a counterparty (e.g., a swap counterparty) terminate its relationship with the Fund, the Fund will seek to utilize other counterparties to seek to maintain its exposures. In addition, the Fund may use options contracts to seek to generate the leverage necessary to implement its strategy. The use of options contracts introduces distinct risks, including heightened volatility, particularly intraday. While options may provide an ancillary benefit of mitigating some losses under specific scenarios, such as severe market downturns, their inherent leverage and rapid price fluctuations can amplify the Fund’s performance volatility and lead to greater risks of substantial losses. Refer to “Derivatives Risk – Options Contracts” for additional information on the risks of investing in options.
In addition, the Fund may enter into swap agreements with a limited number of counterparties, which may increase the Fund’s exposure to counterparty credit risk. Further, there is a risk that no suitable counterparties will be willing to enter into, or continue to enter into, transactions with the Fund and, as a result, the Fund may not be able to achieve its investment objective.

| Risk [Text Block] | Intra-Day Investment Risk. The Fund seeks investment results from the close of the market on a given trading day until the close of the market on the subsequent trading day. The exact exposure of an investment in the Fund intraday in the secondary market is a function of the difference between the share price of the Underlying Security at the market close on the first trading day and the share price of the Underlying Security at the time of purchase. If the share price of the Underlying Security rises, the Fund’s net assets will rise by approximately twice the amount as the Fund’s exposure. Conversely, if the share price of the Underlying Security declines, the Fund’s net assets will decline by approximately two times the amount as the Fund’s exposure. Thus, an investor that purchases Shares intra-day may experience performance that is greater than, or less than, the Fund’s stated leveraged performance of the Underlying Security.
If there is a significant intra-day market event and/or the securities of the Underlying Security experience a significant increase or decrease, the Fund may not meet its investment objective or rebalance its portfolio appropriately.

| Risk [Text Block] | Fixed Income Securities Risk. When the Fund invests in fixed income securities, the value of your investment in the Fund will fluctuate with changes in interest rates. Typically, a rise in interest rates causes a decline in the value of fixed income securities owned by the Fund. In general, the market price of fixed income securities with longer maturities will increase or decrease more in response to changes in interest rates than shorter-term securities. Other risk factors include credit risk (the debtor may default), extension risk (an issuer may exercise its right to repay principal on a fixed rate obligation held by the Fund later than expected), and prepayment risk (the debtor may pay its obligation early, reducing the amount of interest payments). These risks could affect the value of a particular investment by the Fund, possibly causing the Fund’s Share price and total return to be reduced and fluctuate more than other types of investments.

| Risk [Text Block] | Rebalancing Risk. If for any reason the Fund is unable to rebalance all or a portion of its portfolio, or if all or a portion of the portfolio is rebalanced incorrectly, the Fund’s investment exposure may not be consistent with the Fund’s investment objective. In these instances, the Fund may have investment exposure to the Underlying Security that is significantly greater or less than its stated investment objective. As a result, the Fund may be exposed to leverage risk because it had not been properly rebalanced and may not achieve its investment objective.

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] | 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. The costs associated with cash redemptions may include brokerage costs that the Fund may not have incurred if it had made the redemptions in-kind. These costs could be imposed on the Fund, decreasing its NAV, to the extent these costs are not offset by a transaction fee payable by an authorized participant.

(the “Exchange”), and may be traded on U.S. exchanges other than the Exchange, there can be no assurance that Shares will trade with any volume, or at all, on any stock exchange. 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. This adverse effect on liquidity for the Fund’s shares may lead to wider bid-ask spreads and differences between the market price of the Fund’s shares and the underlying value of the shares.

| Risk [Text Block] | Economic and Market Risk. Economies and financial markets throughout the world are becoming increasingly interconnected, which increases the likelihood that events or conditions in one country or region will adversely impact markets or issuers in other countries or regions. Securities in the Fund’s portfolio may underperform in comparison to securities in the general financial markets, a particular financial market, or other asset classes, due to a number of factors, including inflation (or expectations for inflation), deflation (or expectations for deflation), interest rates, global demand for particular products or resources, market instability, financial system instability, debt crises and downgrades, embargoes, tariffs, sanctions and other trade barriers, regulatory events, other governmental trade or market control programs and related geopolitical events. In addition, the value of the Fund’s investments may be negatively affected by the occurrence of global events such as war, terrorism, environmental disasters, natural disasters or events, country instability, and infectious disease epidemics or pandemics. The imposition by the U.S. of tariffs on goods imported from foreign countries and reciprocal tariffs levied on U.S. goods by those countries also may lead to volatility and instability in domestic and foreign markets.

| Risk [Text Block] | High Portfolio Turnover Risk. Daily rebalancing of the Fund’s holdings pursuant to its daily investment objective causes a much greater number of portfolio transactions when compared to most ETFs. Additionally, active market trading of the Fund’s Shares on exchanges (such as the Exchange), could cause more frequent creation and redemption activities, which could increase the number of portfolio transactions. Frequent and active trading may lead to higher transaction costs because of increased broker commissions resulting from such transactions. In addition, there is the possibility of significantly increased short-term capital gains (which will be taxable to shareholders as ordinary income when distributed to them). The Fund calculates portfolio turnover without including the short-term cash instruments or derivative transactions that comprise the majority of the Fund’s trading. As such, if the Fund’s extensive use of derivative instruments were reflected, the calculated portfolio turnover rate would be significantly higher.

| Risk [Text Block] | Tracking Error Risk. Tracking error is the divergence of the Fund’s performance from that of its investment objective which aims to replicate two times the daily percentage change in the price of the Underlying Security. Tracking error may occur for a number of reasons. Tracking error may occur because of transaction costs, the Fund’s holding of cash, differences in accrual of dividends, being under- or overexposed to the Underlying Security or the need to meet new or existing regulatory requirements. Tracking error risk may be heightened during times of market volatility or other unusual market conditions such as market disruptions. The Fund may be required to deviate from its investment objectives, and therefore experience tracking error, as a result of market restrictions or other legal reasons, including regulatory limits or other restrictions on securities that may be purchased by the Adviser and its affiliates.

| Risk [Text Block] | Liquidity Risk. Some securities held by the Fund may be difficult to sell or be illiquid, particularly during times of market turmoil. 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 may prevent the Fund from limiting losses, realizing gains or achieving a high correlation with the Underlying Security. 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] | Trading Halt Risk. Although the Underlying Security’s shares are listed for trading on an exchange, there can be no assurance that an active trading market for such shares will be available at all times and the Exchange may halt trading of such shares in certain circumstances. A halt in trading in the Underlying Security’s shares is expected, in turn, to result in a halt in the trading in the Fund’s Shares. Trading in the Underlying Security’s and/or Fund’s Shares on the Exchange may be halted due to market conditions or for reasons that, in the view of the Exchange, make trading in the Underlying Security’s and/or Fund’s Shares inadvisable. In addition, trading in Underlying Security’s and/or Fund’s Shares on an exchange is subject to trading halts caused by extraordinary market volatility pursuant to exchange “circuit breaker” rules.” In the event of a trading halt for an extended period of time, the Fund may be unable to execute arrangements with swap counterparties that are necessary to implement the Fund’s investment strategy.

| Risk [Text Block] | Tax Risk. The Fund intends to elect and to qualify each year to be treated as a regulated investment company (a “RIC”) under Subchapter M of the Internal Revenue Code of 1986, as amended (“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 swap contracts and options on shares of a single issuer does not exceed 25% of the Fund’s value at the close of any quarter. If the value of swap contracts and options on shares of a single issuer 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] | 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.

| Prospectus [Line Items] | |||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||
| Risk [Text Block] | Compounding and Market Volatility Risk. The Fund has a daily leveraged investment objective and the Fund’s performance for periods greater than a trading day will be the result of each day’s returns compounded over the period, which is very likely to differ from two times (200%) the Underlying Security’s performance, before the Fund’s management fee and other expenses. Compounding affects all investments but has a more significant impact on funds that aim to replicate leveraged daily returns and that rebalance daily. For the Fund aiming to replicate two times the daily performance of an Underlying Security, if adverse daily performance of the Underlying Security reduces the amount of a shareholder’s investment, any further adverse daily performance will lead to a smaller dollar loss because the shareholder’s investment had already been reduced by the prior adverse performance. Equally, however, if favorable daily performance of the Underlying Security increases the amount of a shareholder’s investment, the dollar amount lost due to future adverse performance will increase because the shareholder’s investment has increased.
The effect of compounding becomes more pronounced as the Underlying Security’s volatility and the holding period increase. The impact of compounding will impact each shareholder differently depending on the period of time an investment in the Fund is held and the volatility of the Underlying Security during a shareholder’s holding period of an investment in the Fund.
The chart below provides examples of how the Underlying Security’s volatility could affect the Fund’s performance. The chart illustrates the impact of two factors that affect the Fund’s performance – the Underlying Security’s volatility and the Underlying Security’s performance. The Underlying Security’s performance shows the percentage change in the share price of the Underlying Security over the specified time period, while the Underlying Security’s volatility is a statistical measure of the magnitude of fluctuations in the returns during that time period. As illustrated below, even if the Underlying Security’s performance over two equal time periods is identical, different Underlying Security volatility (i.e., in magnitude of fluctuations in the share price of the Underlying Security) during the two time periods could result in drastically different Fund performance for the two time periods because of compounding daily returns during the time periods.
Fund performance for periods greater than one single day can be estimated given any set of assumptions for the following factors: a) the Underlying Security volatility; b) the Underlying Security performance; c) period of time; d) financing rates associated with leveraged exposure; and e) other Fund expenses. The chart shows estimated Fund returns for a number of combinations of Underlying Security volatility and Underlying Security performance over a one-year period. Performance shown in the chart assumes that: (i) there were no Fund expenses; (ii) borrowing/lending rates (to obtain leveraged exposure) of 0%. If Fund expenses and/or actual borrowing/lending rates were reflected the estimated returns would be different than those shown. Particularly during periods of higher Underlying Security volatility, compounding will cause results for periods longer than a trading day to vary from two times (200%) the performance of the Underlying Security.
As shown in the chart below, the Fund would be expected to lose 6.1% if there was no change in the share price of the Underlying Security over a one-year period during which the Underlying Security experienced annualized volatility of 25%. If the Underlying Security’s annualized volatility were to rise to 75%, the hypothetical loss for a one-year period would widen to approximately -43%. At higher ranges of volatility, there is a chance of a significant loss of value in the Fund, even if there were no change in the share price of the Underlying Security. For instance, if the Underlying Security’s annualized volatility is 100%, the Fund would be expected to lose 63.2% of its value, even if the cumulative Underlying Security change in the share price of the Underlying Security for the year was 0%.
Areas shaded red (or dark gray) represent those scenarios where the Fund can be expected to return less than two times (200%) the performance of the Underlying Security and those shaded green (or light gray) represent those scenarios where the Fund can be expected to return more than two times (200%) the performance of the Underlying Security. The Fund’s actual performance may be significantly better or worse than the performance shown below as a result of any of the factors discussed above or in the “Daily Correlation/Tracking Risk” below.
The Underlying Security’s annualized historical volatility rate for the period from April 4, 2022 (the earliest date available) to March 6, 2026, was 55.39%. The Underlying Security’s annualized performance during this period was -1.81%. Historical Underlying Security volatility and performance are not indications of what Underlying Security volatility and performance will be in the future.

| Risk [Text Block] | Daily Correlation/Tracking Risk. There is no guarantee that the Fund will achieve a high degree of leveraged correlation to the Underlying Security and therefore achieve its daily leveraged investment objective. To achieve a high degree of leveraged correlation with the Underlying Security, the Fund seeks to rebalance its portfolio daily to keep exposure consistent with its daily leveraged investment objective. The possibility of the Fund being materially over- or under-exposed to the Underlying Security increases on days when the Underlying Security is volatile near the close of the trading day. Market disruptions, regulatory restrictions and extreme volatility will also adversely affect the Fund’s ability to adjust exposure to the required levels. If there is a significant intra-day market event and/or the Underlying Security experiences a significant increase or decline, the Fund may not meet its investment objective, be able to rebalance its portfolio appropriately, or may experience significant premiums or discounts, or widened bid-ask spreads.
The Fund may have difficulty achieving its daily leveraged investment objective due to fees, expenses, transaction costs, financing costs related to the use of derivatives, investments in ETFs, directly or indirectly, income items, valuation methodology, accounting standards and disruptions or illiquidity in the markets for the securities or derivatives held by the Fund. The Fund may be subject to large movements of assets into and out of the Fund, potentially resulting in the Fund being over- or under-exposed to the Underlying Security. The Fund may take or refrain from taking positions to improve the tax efficiency or to comply with various regulatory restrictions, either of which may negatively impact the Fund’s leveraged correlation to the Underlying Security.

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

| Risk [Text Block] | 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, leverage, imperfect daily correlations with underlying investments or the Fund’s other portfolio holdings, 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 imperfect correlation between the share price of the Underlying Security 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.
The Fund will be subject to regulatory constraints relating to level of value at risk that the Fund may incur through its derivative portfolio. To the extent the Fund exceeds these regulatory thresholds over an extended period, the Fund may determine that it is necessary to make adjustments to the Fund’s investment strategy, including the desired daily leveraged performance for the Fund.
In addition, the Fund’s investments in derivatives are subject to the following risks:

| Prospectus [Line Items] | |||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||
| Risk [Text Block] | Swap Agreements. The use of swap transactions is a highly specialized activity, which involves investment techniques and risks different from those associated with ordinary portfolio securities transactions. Whether the Fund will be successful in using swap agreements to achieve its investment goal depends on the ability of the Adviser to structure such swap agreements in accordance with the Fund’s investment objective and to identify counterparties for those swap agreements. If the Adviser is unable to enter into swap agreements that provide leveraged exposure to the Underlying Security, the Fund may not meet its stated investment objective. Additionally, any financing, borrowing or other costs associated with using swap transactions may also have the effect of lowering the Fund’s return.
The swap agreements in which the Fund invests are generally traded in the over-the-counter market, which generally has less transparency than exchange-traded derivatives instruments. In a standard swap transaction, two parties agree to exchange the return (or differentials in rates of return) earned or realized on particular predetermined reference assets or underlying securities or instruments. The gross return to be exchanged or swapped between the parties is calculated based on a notional amount or the return on or change in value of a particular dollar amount invested in a basket of securities.
If the Underlying Security has a dramatic move that causes a material decline in the Fund’s net assets, the terms of a swap agreement between the Fund and its counterparty may permit the counterparty to immediately close out the swap transaction with the Fund. In that event, the Fund may be unable to enter into another swap agreement or invest in other derivatives to achieve exposure consistent with the Fund’s investment objective. This may prevent the Fund from achieving its leveraged investment objective, even if the Underlying Security later reverses all or a portion of its movement.

| Prospectus [Line Items] | |||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||
| Risk [Text Block] | 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. The value of the options contracts in which the Fund invests are substantially influenced by the value of the Underlying Security. 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 as 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, as the Fund intends to continuously maintain indirect exposure to the Underlying Security through the use of options contracts, as the options contracts it holds are exercised or expire it will enter into new options contracts, a practice referred to as “rolling.” If the expiring options contracts do not generate proceeds enough to cover the cost of entering into new options contracts, the Fund may experience losses. The use of options to generate leverage introduces additional risks, including significant potential losses if the market moves unfavorably. The leverage inherent in options can amplify both gains and losses, leading to increased volatility and potential for substantial losses, particularly in periods of market uncertainty or low liquidity. Additionally, the Fund may incur losses if the value of the Underlying Security moves against its positions, potentially resulting in a complete loss of the premium paid.

| Prospectus [Line Items] | |||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||
| Risk [Text Block] | Counterparty Risk. The Fund is subject to counterparty risk by virtue of its investments in derivatives which exposes the Fund to the risk that the counterparty will not fulfill its obligation to the Fund. Counterparty risk may arise because of the counterparty’s financial condition (i.e., financial difficulties, bankruptcy, or insolvency), market activities and developments, or other reasons, whether foreseen or not. A counterparty’s inability to fulfill its obligation may result in significant financial loss to the Fund and the Fund may be unable to recover its investment from such counterparty or may obtain a limited and/or delayed recovery.
Counterparties may seek to hedge their exposure to individual clients (such as the Fund) by establishing offsetting exposures with other clients, however, there is no guarantee that counterparties will do so under all circumstances. Should a counterparty (e.g., a swap counterparty) terminate its relationship with the Fund, the Fund will seek to utilize other counterparties to seek to maintain its exposures. In addition, the Fund may use options contracts to seek to generate the leverage necessary to implement its strategy. The use of options contracts introduces distinct risks, including heightened volatility, particularly intraday. While options may provide an ancillary benefit of mitigating some losses under specific scenarios, such as severe market downturns, their inherent leverage and rapid price fluctuations can amplify the Fund’s performance volatility and lead to greater risks of substantial losses. Refer to “Derivatives Risk – Options Contracts” for additional information on the risks of investing in options.
In addition, the Fund may enter into swap agreements with a limited number of counterparties, which may increase the Fund’s exposure to counterparty credit risk. Further, there is a risk that no suitable counterparties will be willing to enter into, or continue to enter into, transactions with the Fund and, as a result, the Fund may not be able to achieve its investment objective.

| Prospectus [Line Items] | |||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||
| Risk [Text Block] | Intra-Day Investment Risk. The Fund seeks investment results from the close of the market on a given trading day until the close of the market on the subsequent trading day. The exact exposure of an investment in the Fund intraday in the secondary market is a function of the difference between the share price of the Underlying Security at the market close on the first trading day and the share price of the Underlying Security at the time of purchase. If the share price of the Underlying Security rises, the Fund’s net assets will rise by approximately twice the amount as the Fund’s exposure. Conversely, if the share price of the Underlying Security declines, the Fund’s net assets will decline by approximately two times the amount as the Fund’s exposure. Thus, an investor that purchases Shares intra-day may experience performance that is greater than, or less than, the Fund’s stated leveraged performance of the Underlying Security.
If there is a significant intra-day market event and/or the securities of the Underlying Security experience a significant increase or decrease, the Fund may not meet its investment objective or rebalance its portfolio appropriately.

| Risk [Text Block] | Fixed Income Securities Risk. When the Fund invests in fixed income securities, the value of your investment in the Fund will fluctuate with changes in interest rates. Typically, a rise in interest rates causes a decline in the value of fixed income securities owned by the Fund. In general, the market price of fixed income securities with longer maturities will increase or decrease more in response to changes in interest rates than shorter-term securities. Other risk factors include credit risk (the debtor may default), extension risk (an issuer may exercise its right to repay principal on a fixed rate obligation held by the Fund later than expected), and prepayment risk (the debtor may pay its obligation early, reducing the amount of interest payments). These risks could affect the value of a particular investment by the Fund, possibly causing the Fund’s Share price and total return to be reduced and fluctuate more than other types of investments.

| Risk [Text Block] | Rebalancing Risk. If for any reason the Fund is unable to rebalance all or a portion of its portfolio, or if all or a portion of the portfolio is rebalanced incorrectly, the Fund’s investment exposure may not be consistent with the Fund’s investment objective. In these instances, the Fund may have investment exposure to the Underlying Security that is significantly greater or less than its stated investment objective. As a result, the Fund may be exposed to leverage risk because it had not been properly rebalanced and may not achieve its investment objective.

| Risk [Text Block] | 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] | 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. The costs associated with cash redemptions may include brokerage costs that the Fund may not have incurred if it had made the redemptions in-kind. These costs could be imposed on the Fund, decreasing its NAV, to the extent these costs are not offset by a transaction fee payable by an authorized participant.

| Risk [Text Block] | Trading. Although Shares are listed on a national securities exchange, such as Cboe BZX Exchange, Inc. (the “Exchange”), and may be traded on U.S. exchanges other than the Exchange, there can be no assurance that Shares will trade with any volume, or at all, on any stock exchange. 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. This adverse effect on liquidity for the Fund’s shares may lead to wider bid-ask spreads and differences between the market price of the Fund’s shares and the underlying value of the shares.

In certain circumstances, such as the disruption of the orderly markets for the financial instruments in which the Fund invests, the Fund might not be able to acquire or dispose of certain holdings quickly or at prices that represent true market value in the judgment of the Adviser. Markets for the financial instruments in which the Fund invests may be disrupted by a number of events, including but not limited to economic crises, health crises, natural disasters, excessive volatility, new legislation, or regulatory changes inside or outside of the U.S. These situations may have an impact on the liquidity of the Fund’s own shares.”

| Risk [Text Block] | Economic and Market Risk. Economies and financial markets throughout the world are becoming increasingly interconnected, which increases the likelihood that events or conditions in one country or region will adversely impact markets or issuers in other countries or regions. Securities in the Fund’s portfolio may underperform in comparison to securities in the general financial markets, a particular financial market, or other asset classes, due to a number of factors, including inflation (or expectations for inflation), deflation (or expectations for deflation), interest rates, global demand for particular products or resources, market instability, financial system instability, debt crises and downgrades, embargoes, tariffs, sanctions and other trade barriers, regulatory events, other governmental trade or market control programs and related geopolitical events. In addition, the value of the Fund’s investments may be negatively affected by the occurrence of global events such as war, terrorism, environmental disasters, natural disasters or events, country instability, and infectious disease epidemics or pandemics. The imposition by the U.S. of tariffs on goods imported from foreign countries and reciprocal tariffs levied on U.S. goods by those countries also may lead to volatility and instability in domestic and foreign markets.

| Risk [Text Block] | High Portfolio Turnover Risk. Daily rebalancing of the Fund’s holdings pursuant to its daily investment objective causes a much greater number of portfolio transactions when compared to most ETFs. Additionally, active market trading of the Fund’s Shares on exchanges (such as the Exchange), could cause more frequent creation and redemption activities, which could increase the number of portfolio transactions. Frequent and active trading may lead to higher transaction costs because of increased broker commissions resulting from such transactions. In addition, there is the possibility of significantly increased short-term capital gains (which will be taxable to shareholders as ordinary income when distributed to them). The Fund calculates portfolio turnover without including the short-term cash instruments or derivative transactions that comprise the majority of the Fund’s trading. As such, if the Fund’s extensive use of derivative instruments were reflected, the calculated portfolio turnover rate would be significantly higher.

| Risk [Text Block] | Tracking Error Risk. Tracking error is the divergence of the Fund’s performance from that of its investment objective which aims to replicate two times the daily percentage change in the price of the Underlying Security. Tracking error may occur for a number of reasons. Tracking error may occur because of transaction costs, the Fund’s holding of cash, differences in accrual of dividends, being under- or overexposed to the Underlying Security or the need to meet new or existing regulatory requirements. Tracking error risk may be heightened during times of market volatility or other unusual market conditions such as market disruptions. The Fund may be required to deviate from its investment objectives, and therefore experience tracking error, as a result of market restrictions or other legal reasons, including regulatory limits or other restrictions on securities that may be purchased by the Adviser and its affiliates.

| Risk [Text Block] | Liquidity Risk. Some securities held by the Fund may be difficult to sell or be illiquid, particularly during times of market turmoil. 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 may prevent the Fund from limiting losses, realizing gains or achieving a high correlation with the Underlying Security. 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] | Trading Halt Risk. Although the Underlying Security’s shares are listed for trading on an exchange, there can be no assurance that an active trading market for such shares will be available at all times and the Exchange may halt trading of such shares in certain circumstances. A halt in trading in the Underlying Security’s shares is expected, in turn, to result in a halt in the trading in the Fund’s Shares. Trading in the Underlying Security’s and/or Fund’s Shares on the Exchange may be halted due to market conditions or for reasons that, in the view of the Exchange, make trading in the Underlying Security’s and/or Fund’s Shares inadvisable. In addition, trading in Underlying Security’s and/or Fund’s Shares on an exchange is subject to trading halts caused by extraordinary market volatility pursuant to exchange “circuit breaker” rules.” In the event of a trading halt for an extended period of time, the Fund may be unable to execute arrangements with swap counterparties that are necessary to implement the Fund’s investment strategy.

| Risk [Text Block] | Tax Risk. The Fund intends to elect and to qualify each year to be treated as a regulated investment company (a “RIC”) under Subchapter M of the Internal Revenue Code of 1986, as amended (“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 swap contracts and options on shares of a single issuer does not exceed 25% of the Fund’s value at the close of any quarter. If the value of swap contracts and options on shares of a single issuer 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] | 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] | Single Issuer Risk. Issuer-specific attributes may cause an investment in the Fund to be more volatile than a traditional pooled investment which diversifies risk or the market generally. The value of the Fund, which focuses on an individual security, 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. Additionally, the Fund will seek to employ its investment strategy as it relates to the underlying issuer regardless of whether there are significant corporate actions such as restructurings, enforcement activity, or acquisitions or periods adverse market, economic, or other conditions and will not seek to take temporary defensive positions during such periods.

| Prospectus [Line Items] | |||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||
| Risk [Text Block] | Compounding and Market Volatility Risk. The Fund has a daily leveraged investment objective and the Fund’s performance for periods greater than a trading day will be the result of each day’s returns compounded over the period, which is very likely to differ from two times (200%) the Underlying Security’s performance, before the Fund’s management fee and other expenses. Compounding affects all investments but has a more significant impact on funds that aim to replicate leveraged daily returns and that rebalance daily. For the Fund aiming to replicate two times the daily performance of an Underlying Security, if adverse daily performance of the Underlying Security reduces the amount of a shareholder’s investment, any further adverse daily performance will lead to a smaller dollar loss because the shareholder’s investment had already been reduced by the prior adverse performance. Equally, however, if favorable daily performance of the Underlying Security increases the amount of a shareholder’s investment, the dollar amount lost due to future adverse performance will increase because the shareholder’s investment has increased.
The effect of compounding becomes more pronounced as the Underlying Security’s volatility and the holding period increase. The impact of compounding will impact each shareholder differently depending on the period of time an investment in the Fund is held and the volatility of the Underlying Security during a shareholder’s holding period of an investment in the Fund.
The chart below provides examples of how the Underlying Security’s volatility could affect the Fund’s performance. The chart illustrates the impact of two factors that affect the Fund’s performance – the Underlying Security’s volatility and the Underlying Security’s performance. The Underlying Security’s performance shows the percentage change in the share price of the Underlying Security over the specified time period, while the Underlying Security’s volatility is a statistical measure of the magnitude of fluctuations in the returns during that time period. As illustrated below, even if the Underlying Security’s performance over two equal time periods is identical, different Underlying Security volatility (i.e., in magnitude of fluctuations in the share price of the Underlying Security) during the two time periods could result in drastically different Fund performance for the two time periods because of compounding daily returns during the time periods.
Fund performance for periods greater than one single day can be estimated given any set of assumptions for the following factors: a) the Underlying Security volatility; b) the Underlying Security performance; c) period of time; d) financing rates associated with leveraged exposure; and e) other Fund expenses. The chart shows estimated Fund returns for a number of combinations of Underlying Security volatility and Underlying Security performance over a one-year period. Performance shown in the chart assumes that: (i) there were no Fund expenses; (ii) borrowing/lending rates (to obtain leveraged exposure) of 0%. If Fund expenses and/or actual borrowing/lending rates were reflected the estimated returns would be different than those shown. Particularly during periods of higher Underlying Security volatility, compounding will cause results for periods longer than a trading day to vary from two times (200%) the performance of the Underlying Security.
As shown in the chart below, the Fund would be expected to lose 6.1% if there was no change in the share price of the Underlying Security over a one-year period during which the Underlying Security experienced annualized volatility of 25%. If the Underlying Security’s annualized volatility were to rise to 75%, the hypothetical loss for a one-year period would widen to approximately -43%. At higher ranges of volatility, there is a chance of a significant loss of value in the Fund, even if there were no change in the share price of the Underlying Security. For instance, if the Underlying Security’s annualized volatility is 100%, the Fund would be expected to lose 63.2% of its value, even if the cumulative Underlying Security change in the share price of the Underlying Security for the year was 0%.
Areas shaded red (or dark gray) represent those scenarios where the Fund can be expected to return less than two times (200%) the performance of the Underlying Security and those shaded green (or light gray) represent those scenarios where the Fund can be expected to return more than two times (200%) the performance of the Underlying Security. The Fund’s actual performance may be significantly better or worse than the performance shown below as a result of any of the factors discussed above or in the “Daily Correlation/Tracking Risk” below.
The Underlying Security’s five-year annualized historical volatility rate for the period ended March 6, 2026, was 33.48%. The Underlying Security’s annualized performance during this period was -6.13%. Historical Underlying Security volatility and performance are not indications of what Underlying Security volatility and performance will be in the future.

| Risk [Text Block] | Daily Correlation/Tracking Risk. There is no guarantee that the Fund will achieve a high degree of leveraged correlation to the Underlying Security and therefore achieve its daily leveraged investment objective. To achieve a high degree of leveraged correlation with the Underlying Security, the Fund seeks to rebalance its portfolio daily to keep exposure consistent with its daily leveraged investment objective. The possibility of the Fund being materially over- or under-exposed to the Underlying Security increases on days when the Underlying Security is volatile near the close of the trading day. Market disruptions, regulatory restrictions and extreme volatility will also adversely affect the Fund’s ability to adjust exposure to the required levels. If there is a significant intra-day market event and/or the Underlying Security experiences a significant increase or decline, the Fund may not meet its investment objective, be able to rebalance its portfolio appropriately, or may experience significant premiums or discounts, or widened bid-ask spreads.
The Fund may have difficulty achieving its daily leveraged investment objective due to fees, expenses, transaction costs, financing costs related to the use of derivatives, investments in ETFs, directly or indirectly, income items, valuation methodology, accounting standards and disruptions or illiquidity in the markets for the securities or derivatives held by the Fund. The Fund may be subject to large movements of assets into and out of the Fund, potentially resulting in the Fund being over- or under-exposed to the Underlying Security. The Fund may take or refrain from taking positions to improve the tax efficiency or to comply with various regulatory restrictions, either of which may negatively impact the Fund’s leveraged correlation to the Underlying Security.

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

| Risk [Text Block] | 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, leverage, imperfect daily correlations with underlying investments or the Fund’s other portfolio holdings, 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 imperfect correlation between the share price of the Underlying Security 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.
The Fund will be subject to regulatory constraints relating to level of value at risk that the Fund may incur through its derivative portfolio. To the extent the Fund exceeds these regulatory thresholds over an extended period, the Fund may determine that it is necessary to make adjustments to the Fund’s investment strategy, including the desired daily leveraged performance for the Fund.
In addition, the Fund’s investments in derivatives are subject to the following risks:

| Risk [Text Block] | Swap Agreements. The use of swap transactions is a highly specialized activity, which involves investment techniques and risks different from those associated with ordinary portfolio securities transactions. Whether the Fund will be successful in using swap agreements to achieve its investment goal depends on the ability of the Adviser to structure such swap agreements in accordance with the Fund’s investment objective and to identify counterparties for those swap agreements. If the Adviser is unable to enter into swap agreements that provide leveraged exposure to the Underlying Security, the Fund may not meet its stated investment objective. Additionally, any financing, borrowing or other costs associated with using swap transactions may also have the effect of lowering the Fund’s return.
The swap agreements in which the Fund invests are generally traded in the over-the-counter market, which generally has less transparency than exchange-traded derivatives instruments. In a standard swap transaction, two parties agree to exchange the return (or differentials in rates of return) earned or realized on particular predetermined reference assets or underlying securities or instruments. The gross return to be exchanged or swapped between the parties is calculated based on a notional amount or the return on or change in value of a particular dollar amount invested in a basket of securities.
If the Underlying Security has a dramatic move that causes a material decline in the Fund’s net assets, the terms of a swap agreement between the Fund and its counterparty may permit the counterparty to immediately close out the swap transaction with the Fund. In that event, the Fund may be unable to enter into another swap agreement or invest in other derivatives to achieve exposure consistent with the Fund’s investment objective. This may prevent the Fund from achieving its leveraged investment objective, even if the Underlying Security later reverses all or a portion of its movement.

| Prospectus [Line Items] | |||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||
| Risk [Text Block] | 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. The value of the options contracts in which the Fund invests are substantially influenced by the value of the Underlying Security. 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 as 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, as the Fund intends to continuously maintain indirect exposure to the Underlying Security through the use of options contracts, as the options contracts it holds are exercised or expire it will enter into new options contracts, a practice referred to as “rolling.” If the expiring options contracts do not generate proceeds enough to cover the cost of entering into new options contracts, the Fund may experience losses. The use of options to generate leverage introduces additional risks, including significant potential losses if the market moves unfavorably. The leverage inherent in options can amplify both gains and losses, leading to increased volatility and potential for substantial losses, particularly in periods of market uncertainty or low liquidity. Additionally, the Fund may incur losses if the value of the Underlying Security moves against its positions, potentially resulting in a complete loss of the premium paid.

| Prospectus [Line Items] | |||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||
| Risk [Text Block] | Counterparty Risk. The Fund is subject to counterparty risk by virtue of its investments in derivatives which exposes the Fund to the risk that the counterparty will not fulfill its obligation to the Fund. Counterparty risk may arise because of the counterparty’s financial condition (i.e., financial difficulties, bankruptcy, or insolvency), market activities and developments, or other reasons, whether foreseen or not. A counterparty’s inability to fulfill its obligation may result in significant financial loss to the Fund and the Fund may be unable to recover its investment from such counterparty or may obtain a limited and/or delayed recovery.
Counterparties may seek to hedge their exposure to individual clients (such as the Fund) by establishing offsetting exposures with other clients, however, there is no guarantee that counterparties will do so under all circumstances. Should a counterparty (e.g., a swap counterparty) terminate its relationship with the Fund, the Fund will seek to utilize other counterparties to seek to maintain its exposures. In addition, the Fund may use options contracts to seek to generate the leverage necessary to implement its strategy. The use of options contracts introduces distinct risks, including heightened volatility, particularly intraday. While options may provide an ancillary benefit of mitigating some losses under specific scenarios, such as severe market downturns, their inherent leverage and rapid price fluctuations can amplify the Fund’s performance volatility and lead to greater risks of substantial losses. Refer to “Derivatives Risk – Options Contracts” for additional information on the risks of investing in options.
In addition, the Fund may enter into swap agreements with a limited number of counterparties, which may increase the Fund’s exposure to counterparty credit risk. Further, there is a risk that no suitable counterparties will be willing to enter into, or continue to enter into, transactions with the Fund and, as a result, the Fund may not be able to achieve its investment objective.

| Risk [Text Block] | Intra-Day Investment Risk. The Fund seeks investment results from the close of the market on a given trading day until the close of the market on the subsequent trading day. The exact exposure of an investment in the Fund intraday in the secondary market is a function of the difference between the share price of the Underlying Security at the market close on the first trading day and the share price of the Underlying Security at the time of purchase. If the share price of the Underlying Security rises, the Fund’s net assets will rise by approximately twice the amount as the Fund’s exposure. Conversely, if the share price of the Underlying Security declines, the Fund’s net assets will decline by approximately two times the amount as the Fund’s exposure. Thus, an investor that purchases Shares intra-day may experience performance that is greater than, or less than, the Fund’s stated leveraged performance of the Underlying Security.
If there is a significant intra-day market event and/or the securities of the Underlying Security experience a significant increase or decrease, the Fund may not meet its investment objective or rebalance its portfolio appropriately.

| Risk [Text Block] | Fixed Income Securities Risk. When the Fund invests in fixed income securities, the value of your investment in the Fund will fluctuate with changes in interest rates. Typically, a rise in interest rates causes a decline in the value of fixed income securities owned by the Fund. In general, the market price of fixed income securities with longer maturities will increase or decrease more in response to changes in interest rates than shorter-term securities. Other risk factors include credit risk (the debtor may default), extension risk (an issuer may exercise its right to repay principal on a fixed rate obligation held by the Fund later than expected), and prepayment risk (the debtor may pay its obligation early, reducing the amount of interest payments). These risks could affect the value of a particular investment by the Fund, possibly causing the Fund’s Share price and total return to be reduced and fluctuate more than other types of investments.

| Risk [Text Block] | Rebalancing Risk. If for any reason the Fund is unable to rebalance all or a portion of its portfolio, or if all or a portion of the portfolio is rebalanced incorrectly, the Fund’s investment exposure may not be consistent with the Fund’s investment objective. In these instances, the Fund may have investment exposure to the Underlying Security that is significantly greater or less than its stated investment objective. As a result, the Fund may be exposed to leverage risk because it had not been properly rebalanced and may not achieve its investment objective.

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] | 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. The costs associated with cash redemptions may include brokerage costs that the Fund may not have incurred if it had made the redemptions in-kind. These costs could be imposed on the Fund, decreasing its NAV, to the extent these costs are not offset by a transaction fee payable by an authorized participant.

(the “Exchange”), and may be traded on U.S. exchanges other than the Exchange, there can be no assurance that Shares will trade with any volume, or at all, on any stock exchange. 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. This adverse effect on liquidity for the Fund’s shares may lead to wider bid-ask spreads and differences between the market price of the Fund’s shares and the underlying value of the shares.

| Risk [Text Block] | Economic and Market Risk. Economies and financial markets throughout the world are becoming increasingly interconnected, which increases the likelihood that events or conditions in one country or region will adversely impact markets or issuers in other countries or regions. Securities in the Fund’s portfolio may underperform in comparison to securities in the general financial markets, a particular financial market, or other asset classes, due to a number of factors, including inflation (or expectations for inflation), deflation (or expectations for deflation), interest rates, global demand for particular products or resources, market instability, financial system instability, debt crises and downgrades, embargoes, tariffs, sanctions and other trade barriers, regulatory events, other governmental trade or market control programs and related geopolitical events. In addition, the value of the Fund’s investments may be negatively affected by the occurrence of global events such as war, terrorism, environmental disasters, natural disasters or events, country instability, and infectious disease epidemics or pandemics. The imposition by the U.S. of tariffs on goods imported from foreign countries and reciprocal tariffs levied on U.S. goods by those countries also may lead to volatility and instability in domestic and foreign markets.

| Risk [Text Block] | High Portfolio Turnover Risk. Daily rebalancing of the Fund’s holdings pursuant to its daily investment objective causes a much greater number of portfolio transactions when compared to most ETFs. Additionally, active market trading of the Fund’s Shares on exchanges (such as the Exchange), could cause more frequent creation and redemption activities, which could increase the number of portfolio transactions. Frequent and active trading may lead to higher transaction costs because of increased broker commissions resulting from such transactions. In addition, there is the possibility of significantly increased short-term capital gains (which will be taxable to shareholders as ordinary income when distributed to them). The Fund calculates portfolio turnover without including the short-term cash instruments or derivative transactions that comprise the majority of the Fund’s trading. As such, if the Fund’s extensive use of derivative instruments were reflected, the calculated portfolio turnover rate would be significantly higher.

| Risk [Text Block] | Tracking Error Risk. Tracking error is the divergence of the Fund’s performance from that of its investment objective which aims to replicate two times the daily percentage change in the price of the Underlying Security. Tracking error may occur for a number of reasons. Tracking error may occur because of transaction costs, the Fund’s holding of cash, differences in accrual of dividends, being under- or overexposed to the Underlying Security or the need to meet new or existing regulatory requirements. Tracking error risk may be heightened during times of market volatility or other unusual market conditions such as market disruptions. The Fund may be required to deviate from its investment objectives, and therefore experience tracking error, as a result of market restrictions or other legal reasons, including regulatory limits or other restrictions on securities that may be purchased by the Adviser and its affiliates.

| Prospectus [Line Items] | |||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||
| Risk [Text Block] | Liquidity Risk. Some securities held by the Fund may be difficult to sell or be illiquid, particularly during times of market turmoil. 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 may prevent the Fund from limiting losses, realizing gains or achieving a high correlation with the Underlying Security. 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] | Money Market Instrument Risk. 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 may lose money.

| Prospectus [Line Items] | |||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||
| Risk [Text Block] | Trading Halt Risk. Although the Underlying Security’s shares are listed for trading on an exchange, there can be no assurance that an active trading market for such shares will be available at all times and the Exchange may halt trading of such shares in certain circumstances. A halt in trading in the Underlying Security’s shares is expected, in turn, to result in a halt in the trading in the Fund’s Shares. Trading in the Underlying Security’s and/or Fund’s Shares on the Exchange may be halted due to market conditions or for reasons that, in the view of the Exchange, make trading in the Underlying Security’s and/or Fund’s Shares inadvisable. In addition, trading in Underlying Security’s and/or Fund’s Shares on an exchange is subject to trading halts caused by extraordinary market volatility pursuant to exchange “circuit breaker” rules.” In the event of a trading halt for an extended period of time, the Fund may be unable to execute arrangements with swap counterparties that are necessary to implement the Fund’s investment strategy.

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

| Defiance Daily Target 2X Long XOVR ETF | U.S. Government and U.S. Agency Obligations Risk [Member] | |||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||
| Prospectus [Line Items] | |||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||
| Risk [Text Block] | 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] | |||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||
| Risk [Text Block] | Tax Risk. The Fund intends to elect and to qualify each year to be treated as a regulated investment company (a “RIC”) under Subchapter M of the Internal Revenue Code of 1986, as amended (“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 swap contracts and options on shares of a single issuer does not exceed 25% of the Fund’s value at the close of any quarter. If the value of swap contracts and options on shares of a single issuer 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.

| Prospectus [Line Items] | |||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||
| Risk [Text Block] | 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.
