| Risk [Text Block] | RIOT Price Appreciation Risk. As part of the Fund’s inverse investment strategy, the Fund purchases and sells swap contracts that are based on the share price of RIOT common stock (the “Underlying Security”). This strategy subjects the Fund to certain of the same risks as if it shorted shares of the Underlying Security, even though it does not. By virtue of the Fund’s indirect -2X exposure to changes in the share price of the Underlying Security, the Fund is subject to the risk that the Underlying Security’s share price increases. If the share price of the Underlying Security increases, the Fund will likely lose value and, as a result, the Fund may suffer significant losses. The Fund may also be subject to the following risks:

| 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 the company has strong earnings reports, or provides positive future guidance, dividend increases, share buybacks, or engages in strategic acquisitions and product launches. Additionally, the Fund will seek to employ its investment strategy as it relates to the underlying issuer regardless of whether there are favorable industry trends, regulatory approvals, analyst upgrades, strategic partnerships, debt reduction, or improved economic conditions.

| Prospectus [Line Items] | |||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||
| Risk [Text Block] | Compounding and Market Volatility Risk. 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 likely to differ from -200% of the Underlying Security’s performance, before fees and expenses. Compounding has a significant impact on funds that are inverse leveraged and that rebalance daily. The impact of compounding becomes more pronounced as volatility and holding periods increase and 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 the shareholder’s holding period of an investment in the Fund.
The chart below provides examples of how Underlying Security volatility could affect the Fund’s performance. Fund performance for periods greater than one single day can be estimated given any set of assumptions for the following factors: a) Underlying Security volatility; b) Underlying Security’s performance; c) period of time; d) financing rates associated with leveraged exposure; e) other Fund expenses; and f) the Underlying Security’s dividends. The chart below illustrates the impact of two principal factors – Underlying Security volatility and performance – on Fund performance. The chart shows estimated Fund returns for a number of combinations of Underlying Security volatility and performance over a one-year period. Performance shown in the chart assumes that (i) there were no Fund expenses; and (ii) borrowing rates (needed to obtain a leveraged short exposure) of 0%. If Fund expenses and/or actual borrowing/lending rates were reflected, the estimated returns would be lower than those shown. Particularly during periods where the Underlying Security experiences higher volatility, compounding will cause results for periods longer than a trading day to vary from -200% of the performance of the Underlying Security.
As shown in the chart below, the Fund would be expected to lose 17.10% if the Underlying Security provided no return over a one-year period during which the Underlying Security experienced annualized volatility of 25%. At higher ranges of volatility, there is a chance of a significant loss of value in the Fund, even if the Underlying Security return is flat.
For instance, if the Underlying Security’s annualized volatility is 100%, the Inverse Fund would be expected to lose 95% of its value, even if the cumulative Underlying Security’s return for the year was 0%. Areas shaded red (or dark gray) represent those scenarios where the Inverse Fund can be expected to return less than -200% of 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 -200% of the performance of the Underlying Security. The Inverse Fund’s actual returns may be significantly better or worse than the returns shown below as a result of any of the factors discussed above or in “Tracking Error Risk” below.
The Underlying Security’s annualized historical volatility rate for the five-year period ended June 30, 22026 was 92.74%. The Underlying Security’s highest volatility rate for any one 12-month period during this period was 103.71% and volatility for a shorter period of time may have been substantially higher. The Underlying Security’s annualized performance during this period was -6.18%. Historical Underlying Security volatility and performance are not indications of what Underlying Security volatility and performance will be in the future.

| Prospectus [Line Items] | |||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||
| Risk [Text Block] | Daily Correlation/Tracking Risk. There is no guarantee that the Fund will achieve a high degree of inverse correlation to the Underlying Security and therefore achieve its daily inverse investment objective. To achieve a high degree of 2 times inverse correlation with the Underlying Security, the Fund seeks to rebalance its portfolio daily to keep exposure consistent with its daily inverse investment objective. The possibility of the Fund being materially over-exposed (meaning providing more than -200% exposure to the Underlying Security – i.e., -201% or greater) or under-exposed (meaning providing less than -200% exposure to the Underlying Security – i.e., -199% or less) 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 2 times inverse 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 2 times inverse correlation to the Underlying Security.

| Prospectus [Line Items] | |||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||
| Risk [Text Block] | Short Sale Exposure Risk. The Fund will seek inverse or “short” exposure through financial instruments, which would cause the Fund to be exposed to certain risks associated with selling short. These risks include, under certain market conditions, an increase in the volatility and decrease in the liquidity of the instruments underlying the short position, which may lower the Fund’s return, result in a loss, have the effect of limiting the Fund’s ability to obtain inverse exposure through financial instruments, or require the Fund to seek inverse exposure through alternative investment strategies that may be less desirable or more costly to implement. To the extent that, at any particular point in time, the instruments underlying the short position may be thinly traded or have a limited market, including due to regulatory action, the Fund may be unable to meet its investment objective due to a lack of available securities or counterparties. During such periods, the Fund’s ability to issue additional Shares may be adversely affected. Obtaining inverse exposure through these instruments may be considered an aggressive investment technique. Any income, dividends or payments by any assets underlying the Fund’s short positions, if any, would negatively impact the Fund. The Fund could lose an amount greater than its net assets in the event the Underlying Security increases more than 50%.

| Prospectus [Line Items] | |||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||
| 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 value 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. If the Fund exceeds these regulatory thresholds, it may adjust its portfolio. These adjustments may cause the Fund to fail to achieve investment results, before fees and expenses, that correspond to -200% of the daily performance of the Underlying Security and may result in substantially lower returns during these periods. 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 inverse performance for the Fund. |

| Defiance Daily Target 2X Short RIOT ETF | Swap Agreements [Member] | |||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||
| 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 inverse 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 inverse investment objective, even if the Underlying Security later reverses all or a portion of its movement.

| Defiance Daily Target 2X Short RIOT ETF | Options Contracts [Member] | |||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||
| 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 value of the Underlying Security at the market close on the first trading day and the value of the Underlying Security at the time of purchase. If the Underlying Security declines in value, the Fund’s net assets will rise by the same amount as the Fund’s exposure. Conversely, if the Underlying Security gains in value, the Fund’s net assets will decline by the same 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 inverse 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.

| Prospectus [Line Items] | |||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||
| 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 The Nasdaq Stock Market, LLC (the “Exchange”), and may be traded on U.S. exchanges other than the Exchange, there can be no assurance that 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 Funds 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 such exchanges as The Nasdaq Stock Market, LLC, 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 -2X 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, such as market rules related to short sales, may prevent the Fund from limiting losses, realizing gains or achieving a high correlation with the Underlying 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 RIC under Subchapter M of the Code. As a RIC, the Fund will not be subject to U.S. federal income tax on the portion of its net investment income and net capital gain that it distributes to Shareholders, provided that it satisfies certain requirements of the Code. If the Fund does not qualify as a RIC for any taxable year and certain relief provisions are not available, the Fund’s taxable income will be subject to tax at the Fund level and to a further tax at the shareholder level when such income is distributed. To comply with the asset diversification test applicable to a RIC, the Fund will attempt to ensure that the value of 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] | Compounding and Market Volatility Risk. 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 likely to differ from -200% of the Underlying Security’s performance, before fees and expenses. Compounding has a significant impact on funds that are inverse leveraged and that rebalance daily. The impact of compounding becomes more pronounced as volatility and holding periods increase and 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 the shareholder’s holding period of an investment in the Fund.
The chart below provides examples of how Underlying Security volatility could affect the Fund’s performance. Fund performance for periods greater than one single day can be estimated given any set of assumptions for the following factors: a) Underlying Security volatility; b) Underlying Security’s performance; c) period of time; d) financing rates associated with leveraged exposure; e) other Fund expenses; and f) the Underlying Security’s dividends. The chart below illustrates the impact of two principal factors – Underlying Security volatility and performance – on Fund performance. The chart shows estimated Fund returns for a number of combinations of Underlying Security volatility and performance over a one-year period. Performance shown in the chart assumes that (i) there were no Fund expenses; and (ii) borrowing rates (needed to obtain a leveraged short exposure) of 0%. If Fund expenses and/or actual borrowing/lending rates were reflected, the estimated returns would be lower than those shown. Particularly during periods where the Underlying Security experiences higher volatility, compounding will cause results for periods longer than a trading day to vary from -200% of the performance of the Underlying Security.
As shown in the chart below, the Fund would be expected to lose 17.10% if the Underlying Security provided no return over a one-year period during which the Underlying Security experienced annualized volatility of 25%. At higher ranges of volatility, there is a chance of a significant loss of value in the Fund, even if the Underlying Security return is flat.
For instance, if the Underlying Security’s annualized volatility is 100%, the Inverse Fund would be expected to lose 95% of its value, even if the cumulative Underlying Security’s return for the year was 0%. Areas shaded red (or dark gray) represent those scenarios where the Inverse Fund can be expected to return less than -200% of 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 -200% of the performance of the Underlying Security. The Inverse Fund’s actual returns may be significantly better or worse than the returns shown below as a result of any of the factors discussed above or in “Tracking Error Risk” below.
The Underlying Security’s annualized historical volatility rate for the five-year period ended June 30, 2026 was 87.04%. The Underlying Security’s highest volatility rate for any one 12-month period during this period was 113.96% and volatility for a shorter period of time may have been substantially higher. The Underlying Security’s annualized performance during this period was 52.79%. 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 inverse correlation to the Underlying Security and therefore achieve its daily inverse investment objective. To achieve a high degree of 2 times inverse correlation with the Underlying Security, the Fund seeks to rebalance its portfolio daily to keep exposure consistent with its daily inverse investment objective. The possibility of the Fund being materially over-exposed (meaning providing more than -200% exposure to the Underlying Security – i.e., -201% or greater) or under-exposed (meaning providing less than -200% exposure to the Underlying Security – i.e., -199% or less) 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 2 times inverse 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 2 times inverse correlation to the Underlying Security.

| Risk [Text Block] | Short Sale Exposure Risk. The Fund will seek inverse or “short” exposure through financial instruments, which would cause the Fund to be exposed to certain risks associated with selling short. These risks include, under certain market conditions, an increase in the volatility and decrease in the liquidity of the instruments underlying the short position, which may lower the Fund’s return, result in a loss, have the effect of limiting the Fund’s ability to obtain inverse exposure through financial instruments, or require the Fund to seek inverse exposure through alternative investment strategies that may be less desirable or more costly to implement. To the extent that, at any particular point in time, the instruments underlying the short position may be thinly traded or have a limited market, including due to regulatory action, the Fund may be unable to meet its investment objective due to a lack of available securities or counterparties. During such periods, the Fund’s ability to issue additional Shares may be adversely affected. Obtaining inverse exposure through these instruments may be considered an aggressive investment technique. Any income, dividends or payments by any assets underlying the Fund’s short positions, if any, would negatively impact the Fund. The Fund could lose an amount greater than its net assets in the event the Underlying Security increases more than 50%.

| 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 value 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. If the Fund exceeds these regulatory thresholds, it may adjust its portfolio. These adjustments may cause the Fund to fail to achieve investment results, before fees and expenses, that correspond to -200% of the daily performance of the Underlying Security and may result in substantially lower returns during these periods. 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 inverse performance for the Fund. |

| 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 inverse 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 inverse 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 value of the Underlying Security at the market close on the first trading day and the value of the Underlying Security at the time of purchase. If the Underlying Security declines in value, the Fund’s net assets will rise by the same amount as the Fund’s exposure. Conversely, if the Underlying Security gains in value, the Fund’s net assets will decline by the same 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 inverse 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] | 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.

Although Shares are listed on a national securities exchange, such as The Nasdaq Stock Market, LLC (the “Exchange”), and may be traded on U.S. exchanges other than the Exchange, there can be no assurance that 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 Funds 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 such exchanges as The Nasdaq Stock Market, LLC, 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 -2X 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, such as market rules related to short sales, may prevent the Fund from limiting losses, realizing gains or achieving a high correlation with the Underlying 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 RIC under Subchapter M of the Code. As a RIC, the Fund will not be subject to U.S. federal income tax on the portion of its net investment income and net capital gain that it distributes to Shareholders, provided that it satisfies certain requirements of the Code. If the Fund does not qualify as a RIC for any taxable year and certain relief provisions are not available, the Fund’s taxable income will be subject to tax at the Fund level and to a further tax at the shareholder level when such income is distributed. To comply with the asset diversification test applicable to a RIC, the Fund will attempt to ensure that the value of 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] | SMCI Price Appreciation Risk. As part of the Fund’s inverse investment strategy, the Fund purchases and sells swap contracts that are based on the share price of SMCI common stock (the “Underlying Security”). This strategy subjects the Fund to certain of the same risks as if it shorted shares of the Underlying Security, even though it does not. By virtue of the Fund’s indirect -2X exposure to changes in the share price of the Underlying Security, the Fund is subject to the risk that the Underlying Security’s share price increases. If the share price of the Underlying Security increases, the Fund will likely lose value and, as a result, the Fund may suffer significant losses. The Fund may also be subject to the following risks:

| Prospectus [Line Items] | |||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||
| Risk [Text Block] | Compounding and Market Volatility Risk. 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 likely to differ from -200% of the Underlying Security’s performance, before fees and expenses. Compounding has a significant impact on funds that are inverse leveraged and that rebalance daily. The impact of compounding becomes more pronounced as volatility and holding periods increase and 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 the shareholder’s holding period of an investment in the Fund.
The chart below provides examples of how Underlying Security volatility could affect the Fund’s performance. Fund performance for periods greater than one single day can be estimated given any set of assumptions for the following factors: a) Underlying Security volatility; b) Underlying Security’s performance; c) period of time; d) financing rates associated with leveraged exposure; e) other Fund expenses; and f) the Underlying Security’s dividends. The chart below illustrates the impact of two principal factors – Underlying Security volatility and performance – on Fund performance. The chart shows estimated Fund returns for a number of combinations of Underlying Security volatility and performance over a one-year period. Performance shown in the chart assumes that (i) there were no Fund expenses; and (ii) borrowing rates (needed to obtain a leveraged short exposure) of 0%. If Fund expenses and/or actual borrowing/lending rates were reflected, the estimated returns would be lower than those shown. Particularly during periods where the Underlying Security experiences higher volatility, compounding will cause results for periods longer than a trading day to vary from -200% of the performance of the Underlying Security.
As shown in the chart below, the Fund would be expected to lose 17.10% if the Underlying Security provided no return over a one-year period during which the Underlying Security experienced annualized volatility of 25%. At higher ranges of volatility, there is a chance of a significant loss of value in the Fund, even if the Underlying Security return is flat.
For instance, if the Underlying Security’s annualized volatility is 100%, the Inverse Fund would be expected to lose 95% of its value, even if the cumulative Underlying Security’s return for the year was 0%. Areas shaded red (or dark gray) represent those scenarios where the Inverse Fund can be expected to return less than -200% of 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 -200% of the performance of the Underlying Security. The Inverse Fund’s actual returns may be significantly better or worse than the returns shown below as a result of any of the factors discussed above or in “Tracking Error Risk” below.
The Underlying Security’s annualized historical volatility rate for the five-year period ended June 30, 2026 was 32.33%. The Underlying Security’s highest volatility rate for any one 12-month period during this period was 39.42% and volatility for a shorter period of time may have been substantially higher. The Underlying Security’s annualized performance during this period was 39.17%. 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 inverse correlation to the Underlying Security and therefore achieve its daily inverse investment objective. To achieve a high degree of 2 times inverse correlation with the Underlying Security, the Fund seeks to rebalance its portfolio daily to keep exposure consistent with its daily inverse investment objective. The possibility of the Fund being materially over-exposed (meaning providing more than -200% exposure to the Underlying Security – i.e., -201% or greater) or under-exposed (meaning providing less than -200% exposure to the Underlying Security – i.e., -199% or less) 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 2 times inverse 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 2 times inverse correlation to the Underlying Security.

| Risk [Text Block] | Short Sale Exposure Risk. The Fund will seek inverse or “short” exposure through financial instruments, which would cause the Fund to be exposed to certain risks associated with selling short. These risks include, under certain market conditions, an increase in the volatility and decrease in the liquidity of the instruments underlying the short position, which may lower the Fund’s return, result in a loss, have the effect of limiting the Fund’s ability to obtain inverse exposure through financial instruments, or require the Fund to seek inverse exposure through alternative investment strategies that may be less desirable or more costly to implement. To the extent that, at any particular point in time, the instruments underlying the short position may be thinly traded or have a limited market, including due to regulatory action, the Fund may be unable to meet its investment objective due to a lack of available securities or counterparties. During such periods, the Fund’s ability to issue additional Shares may be adversely affected. Obtaining inverse exposure through these instruments may be considered an aggressive investment technique. Any income, dividends or payments by any assets underlying the Fund’s short positions, if any, would negatively impact the Fund. The Fund could lose an amount greater than its net assets in the event the Underlying Security increases more than 50%.

| 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 value 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. If the Fund exceeds these regulatory thresholds, it may adjust its portfolio. These adjustments may cause the Fund to fail to achieve investment results, before fees and expenses, that correspond to -200% of the daily performance of the Underlying Security and may result in substantially lower returns during these periods. 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 inverse performance for the Fund. |

| 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 inverse 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 inverse 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 value of the Underlying Security at the market close on the first trading day and the value of the Underlying Security at the time of purchase. If the Underlying Security declines in value, the Fund’s net assets will rise by the same amount as the Fund’s exposure. Conversely, if the Underlying Security gains in value, the Fund’s net assets will decline by the same 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 inverse 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.

Although Shares are listed on a national securities exchange, such as The Nasdaq Stock Market, LLC (the “Exchange”), and may be traded on U.S. exchanges other than the Exchange, there can be no assurance that 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 such exchanges as The Nasdaq Stock Market, LLC, 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 -2X 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, such as market rules related to short sales, may prevent the Fund from limiting losses, realizing gains or achieving a high correlation with the Underlying 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 RIC under Subchapter M of the Code. As a RIC, the Fund will not be subject to U.S. federal income tax on the portion of its net investment income and net capital gain that it distributes to Shareholders, provided that it satisfies certain requirements of the Code. If the Fund does not qualify as a RIC for any taxable year and certain relief provisions are not available, the Fund’s taxable income will be subject to tax at the Fund level and to a further tax at the shareholder level when such income is distributed. To comply with the asset diversification test applicable to a RIC, the Fund will attempt to ensure that the value of 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] | Compounding and Market Volatility Risk. 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 likely to differ from -200% of the Underlying Security’s performance, before fees and expenses. Compounding has a significant impact on funds that are inverse leveraged and that rebalance daily. The impact of compounding becomes more pronounced as volatility and holding periods increase and 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 the shareholder’s holding period of an investment in the Fund.
The chart below provides examples of how Underlying Security volatility could affect the Fund’s performance. Fund performance for periods greater than one single day can be estimated given any set of assumptions for the following factors: a) Underlying Security volatility; b) Underlying Security’s performance; c) period of time; d) financing rates associated with leveraged exposure; e) other Fund expenses; and f) the Underlying Security’s dividends. The chart below illustrates the impact of two principal factors – Underlying Security volatility and performance – on Fund performance. The chart shows estimated Fund returns for a number of combinations of Underlying Security volatility and performance over a one-year period. Performance shown in the chart assumes that (i) there were no Fund expenses; and (ii) borrowing rates (needed to obtain a leveraged short exposure) of 0%. If Fund expenses and/or actual borrowing/lending rates were reflected, the estimated returns would be lower than those shown. Particularly during periods where the Underlying Security experiences higher volatility, compounding will cause results for periods longer than a trading day to vary from -200% of the performance of the Underlying Security.
As shown in the chart below, the Fund would be expected to lose 17.10% if the Underlying Security provided no return over a one-year period during which the Underlying Security experienced annualized volatility of 25%. At higher ranges of volatility, there is a chance of a significant loss of value in the Fund, even if the Underlying Security return is flat.
For instance, if the Underlying Security’s annualized volatility is 100%, the Inverse Fund would be expected to lose 95% of its value, even if the cumulative Underlying Security’s return for the year was 0%. Areas shaded red (or dark gray) represent those scenarios where the Inverse Fund can be expected to return less than -200% of 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 -200% of the performance of the Underlying Security. The Inverse Fund’s actual returns may be significantly better or worse than the returns shown below as a result of any of the factors discussed above or in “Tracking Error Risk” below.
The Underlying Security’s annualized historical volatility rate for the five-year period ended June 30, 2026, was 90.46%. During the five-year period observed the Underlying Security’s highest volatility rate over a 12-month period was 97.93% and volatility for a shorter period of time may have been substantially higher. The Underlying Security’s annualized performance for the five-year period ended June 30, 2026, was 5.52%. Historical volatility and performance are not indications of what the 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 inverse correlation to the Underlying Security and therefore achieve its daily inverse investment objective. To achieve a high degree of 2 times inverse correlation with the Underlying Security, the Fund seeks to rebalance its portfolio daily to keep exposure consistent with its daily inverse investment objective. The possibility of the Fund being materially over-exposed (meaning providing more than -200% exposure to the Underlying Security – i.e., -201% or greater) or under-exposed (meaning providing less than -200% exposure to the Underlying Security – i.e., -199% or less) 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 2 times inverse 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 2 times inverse correlation to the Underlying Security.

| Risk [Text Block] | Short Sale Exposure Risk. The Fund will seek inverse or “short” exposure through financial instruments, which would cause the Fund to be exposed to certain risks associated with selling short. These risks include, under certain market conditions, an increase in the volatility and decrease in the liquidity of the instruments underlying the short position, which may lower the Fund’s return, result in a loss, have the effect of limiting the Fund’s ability to obtain inverse exposure through financial instruments, or require the Fund to seek inverse exposure through alternative investment strategies that may be less desirable or more costly to implement. To the extent that, at any particular point in time, the instruments underlying the short position may be thinly traded or have a limited market, including due to regulatory action, the Fund may be unable to meet its investment objective due to a lack of available securities or counterparties. During such periods, the Fund’s ability to issue additional Shares may be adversely affected. Obtaining inverse exposure through these instruments may be considered an aggressive investment technique. Any income, dividends or payments by any assets underlying the Fund’s short positions, if any, would negatively impact the Fund. The Fund could lose an amount greater than its net assets in the event the Underlying Security increases more than 50%.

| 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 value 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. If the Fund exceeds these regulatory thresholds, it may adjust its portfolio. These adjustments may cause the Fund to fail to achieve investment results, before fees and expenses, that correspond to -200% of the daily performance of the Underlying Security and may result in substantially lower returns during these periods. 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 inverse performance for the Fund. |

| 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 inverse 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 inverse 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 value of the Underlying Security at the market close on the first trading day and the value of the Underlying Security at the time of purchase. If the Underlying Security declines in value, the Fund’s net assets will rise by the same amount as the Fund’s exposure. Conversely, if the Underlying Security gains in value, the Fund’s net assets will decline by the same 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 inverse 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.

Although Shares are listed on a national securities exchange, such as The Nasdaq Stock Market, LLC (the “Exchange”), and may be traded on U.S. exchanges other than the Exchange, there can be no assurance that 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 such exchanges as The Nasdaq Stock Market, LLC, 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 -2X 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, such as market rules related to short sales, may prevent the Fund from limiting losses, realizing gains or achieving a high correlation with the Underlying 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 RIC under Subchapter M of the Code. As a RIC, the Fund will not be subject to U.S. federal income tax on the portion of its net investment income and net capital gain that it distributes to Shareholders, provided that it satisfies certain requirements of the Code. If the Fund does not qualify as a RIC for any taxable year and certain relief provisions are not available, the Fund’s taxable income will be subject to tax at the Fund level and to a further tax at the shareholder level when such income is distributed. To comply with the asset diversification test applicable to a RIC, the Fund will attempt to ensure that the value of 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.

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.

| 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 five-year period ended June 30, 2026 was 83.03%. The Underlying Security’s highest volatility rate for any one calendar year during this period was 115.50% and volatility for a shorter period of time may have been substantially higher. The Underlying Security’s annualized performance during this period was 26.05%. 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] | 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.

| 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.

Although Shares are listed on a national securities exchange, such as The Nasdaq Stock Market, LLC (the “Exchange”), and may be traded on U.S. exchanges other than the Exchange, there can be no assurance that 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. 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] | 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.

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 (the “Code”). As a RIC, the Fund will not be subject to U.S. federal income tax on the portion of its net investment income and net capital gain that it distributes to Shareholders, provided that it satisfies certain requirements of the Code. If the Fund does not qualify as a RIC for any taxable year and certain relief provisions are not available, the Fund’s taxable income will be subject to tax at the Fund level and to a further tax at the shareholder level when such income is distributed. To comply with the asset diversification test applicable to a RIC, the Fund will attempt to ensure that the value of 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.

The healthcare providers and services industry can be significantly affected by changing economic conditions, evolving patient demographics, and fluctuations in demand for healthcare services. Profitability in this industry is often dependent on reimbursement rates from government programs and private payors, as well as the ability to manage operational costs effectively. Changes in healthcare regulations and policies, including those related to insurance coverage and reimbursement, can materially impact the industry. Companies in the healthcare providers and services industry are subject to extensive and frequently changing government regulation, which may affect the scope of their activities, the rates they can charge for services, and their compliance costs.

| Risk [Text Block] | Business Risks. HIMS’s limited operating history and evolving business model make it difficult to evaluate its prospects, and fluctuations in its operational results and key performance metrics could lead to unmet investor expectations. The ability to expand offerings, attract and retain customers, and navigate evolving privacy, healthcare, and regulatory frameworks is critical; failure in these areas could materially and adversely impact HIMS’s business and financial condition. HIMS operates in highly competitive markets, facing challenges from established healthcare providers, retailers, pharmaceutical companies, and technology firms, which may affect its competitive position. Additionally, the success of HIMS is heavily reliant on its brand reputation, relationships with healthcare providers and medical groups, and compliance with complex healthcare and pharmacy regulations. Security breaches, data loss, legal proceedings, or regulatory changes could harm its operations and reputation. HIMS may require additional capital to support growth, which may not be available on favorable terms. Furthermore, its dual-class stock structure concentrates voting power with the company’s CEO, limiting investors’ influence on critical decisions.

| 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] | 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 five-year period ended June 30, 2026 was 99.29%. The Underlying Security’s highest volatility rate for any one calendar year during this period was 126.05% and volatility for a shorter period of time may have been substantially higher. The Underlying Security’s annualized performance during this period was 37.85%. 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] | 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] | 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 The Nasdaq Stock Market, LLC (the “Exchange”), and may be traded on U.S. exchanges other than the Exchange, there can be no assurance that 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. 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] | 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] | 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 (the “Code”). As a RIC, the Fund will not be subject to U.S. federal income tax on the portion of its net investment income and net capital gain that it distributes to Shareholders, provided that it satisfies certain requirements of the Code. If the Fund does not qualify as a RIC for any taxable year and certain relief provisions are not available, the Fund’s taxable income will be subject to tax at the Fund level and to a further tax at the shareholder level when such income is distributed. To comply with the asset diversification test applicable to a RIC, the Fund will attempt to ensure that the value of 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] | Business Risks: IONQ is an early-stage business with a limited operating history, a history of operating losses, and an expectation of significant expenses and losses for the foreseeable future. IONQ faces challenges scaling its business, managing growth, and effectively executing its strategies in a nascent and volatile quantum computing industry. The company’s success is highly dependent on its ability to develop scalable quantum computing systems, achieve cost reductions, and maintain competitive positioning in a rapidly evolving market. IONQ has not produced a scalable quantum computer and faces significant barriers in its attempts to produce quantum computers. There is no assurance that IONQ’s technology will achieve broad market adoption, particularly given the technical and economic challenges of the quantum computing sector.
IONQ’s reliance on key employees and its ability to retain talent with specialized knowledge is critical to its operations. Additionally, much of its revenue is concentrated among a few customers, making the business vulnerable to contract terminations or customer loss. Dependence on proprietary ion trap technology and specific isotopic materials introduces supply chain risks, while compatibility with industry-standard software and hardware remains a concern. Intellectual property risks, including the loss or compromise of trade secrets, inability to maintain patent protections, or litigation claims, could harm the company’s competitive edge.
IONQ is also exposed to risks related to international expansion, government contracts, and regulatory changes, including tariffs and trade restrictions. Operational disruptions, cybersecurity threats, and adverse global economic conditions could further impact IONQ’s growth and profitability. If IONQ fails to meet market expectations or achieve forecasted growth, its stock price and long-term prospects could be materially affected.

| 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] | Technology Hardware, Storage & Peripherals Risks. Companies in the technology hardware, storage, and peripherals industry may face intense competition, both domestically and internationally, which can pressure profit margins and market share. These companies often rely on complex supply chains and third-party providers for components, manufacturing, and services. Supply chain disruptions, including the unavailability of critical materials or components, price increases, or delays in production, can adversely affect operations. Many companies in this industry depend on a limited number of suppliers or suppliers concentrated in specific geographic regions, which may increase vulnerability to geopolitical risks, natural disasters, or regulatory changes. Identifying and qualifying alternative suppliers can be time-consuming and costly, with no guarantee of availability. Additionally, operations may be impacted by resource constraints, including shortages of electricity, rare earth elements, or other essential materials. Companies in this industry are also exposed to cybersecurity threats, intellectual property risks, and evolving technological standards, which may increase operational costs and hinder competitiveness.

| Risk [Text Block] | Quantum Computing Risk. Quantum computing may be significantly affected by intense competition, aggressive pricing dynamics, rapid technological advancements, and the risk of product obsolescence. Quantum computing companies face substantial competitive pressures, including competition for market share, the entry of new participants, and short innovation cycles driven by accelerated technological developments. These factors may result in limited earnings potential, declining profit margins, or both. Quantum computing companies are also exposed to the risk that their technologies, products, or services may fail to gain acceptance by consumers or businesses or may become rapidly outdated due to evolving advancements. The success of many quantum computing companies depends heavily on patent protection and intellectual property rights, making the cost of obtaining (or failing to obtain) patent approvals, litigating patent disputes, and the potential loss of patent protection critical factors affecting profitability. The expiration or invalidation of key patents can intensify pricing pressures and materially reduce profitability. Additionally, many companies in this sector have limited operating histories, adding to the uncertainty of their financial stability and long-term viability. Securities of quantum computing companies have historically demonstrated higher volatility compared to broader markets, particularly over shorter time frames, reflecting the speculative nature of the industry and the risks inherent in pioneering emerging technologies.

| 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 five-year period ended June 30, 2026 was 79.43%. The Underlying Security’s highest volatility rate for any one calendar year during this period was 91.57% and volatility for a shorter period of time may have been substantially higher. The Underlying Security’s annualized performance during this period was 56.28%. 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] | 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.

| 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 The Nasdaq Stock Market, LLC (the “Exchange”), and may be traded on U.S. exchanges other than the Exchange, there can be no assurance that 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. 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] | 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 (the “Code”). As a RIC, the Fund will not be subject to U.S. federal income tax on the portion of its net investment income and net capital gain that it distributes to Shareholders, provided that it satisfies certain requirements of the Code. If the Fund does not qualify as a RIC for any taxable year and certain relief provisions are not available, the Fund’s taxable income will be subject to tax at the Fund level and to a further tax at the shareholder level when such income is distributed. To comply with the asset diversification test applicable to a RIC, the Fund will attempt to ensure that the value of 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.

| Risk [Text Block] | Business Risks. RKLB has experienced rapid growth, with its employee base and operations expanding substantially in recent years, placing considerable demands on its management, operational infrastructure, and financial resources. Continued growth is dependent on RKLB’s ability to scale its revenue, improve operational efficiencies, and maintain profitability while effectively managing its increasingly complex organizational structure. Failure to integrate acquisitions, enhance business processes, or address evolving customer and market demands could adversely affect RKLB’s growth prospects.
RKLB operates in competitive markets for rocket launch services, mission services, spacecraft, and spacecraft components, facing challenges from established players and new entrants. RKLB’s success relies on its ability to anticipate and respond to macroeconomic and industry-specific changes, hire and retain talent, and maintain high levels of customer satisfaction. Additionally, interruptions from information technology failures, cybersecurity breaches, or other infrastructure issues could disrupt operations. RKLB’s ability to comply with applicable regulations and adapt to changes in the industry also presents ongoing risks.
While RKLB has demonstrated significant revenue growth in recent years, future revenue generation and growth are uncertain. Rising operating expenses may outpace revenue growth, potentially harming profitability and the company’s overall financial condition. RKLB experienced net losses of $198.2 million, $190.2 million and $182.6 million for the years ended December 31, 2025, 2024 and 2023, respectively, and expects to continue to incur net losses for at least the next 12 months and RKLB may not achieve or maintain profitability in the future. Failure to address these risks could materially impact RKLB’s business and long-term prospects.

| 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] | RKLB Performance Risk. RKLB may fail to meet its publicly announced guidelines or other expectations about its business, which could cause the price of RKLB to decline. RKLB provides guidance regarding its expected financial and business performance, such as projections regarding sales and production. Correctly identifying key factors affecting business conditions and predicting future events is inherently an uncertain process, and the guidance RKLB provides may not ultimately be accurate. If RKLB’s guidance is not accurate or varies from actual results due to its inability to meet the assumptions or the impact on its financial performance that could occur as a result of various risks and uncertainties, the market value of common stock issued by RKLB could decline significantly.

| Risk [Text Block] | Aerospace & Defense Industry Risks. Companies in the aerospace and defense industry are subject to risks stemming from their reliance on government budgets and spending priorities, which can fluctuate due to political and economic pressures. These companies often operate in highly competitive markets and may face challenges from both domestic and international competitors. The aerospace and defense industry is also affected by geopolitical tensions, trade policies, and regulatory changes that can impact market access and operational efficiency. Aerospace and defense companies typically rely on complex supply chains for specialized components and materials. Disruptions in these supply chains, whether due to shortages, price increases, or geopolitical factors, can significantly affect production and profitability. Additionally, technological advancements are critical for maintaining competitiveness in this sector, but the high cost and uncertain outcomes of research and development efforts may pose financial risks. Companies in this industry face heightened cybersecurity risks due to the sensitive nature of their technologies, and breaches can lead to operational disruptions, reputational damage, and regulatory scrutiny. Long-term fixed-cost contracts, which are common in this sector, may expose companies to financial losses if costs exceed estimates. Furthermore, environmental and safety regulations, as well as export controls, tariffs, and trade restrictions, impose significant compliance costs and may limit market opportunities. The aerospace and defense industry is inherently cyclical and influenced by global political and economic developments, which can contribute to earnings volatility and investment risks.

| 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.

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 of July 28, 2021 to June 30, 2026 (the maximum period available) was 72.74%. The Underlying Security’s highest volatility rate for any one calendar year during this period was 97.36% and volatility for a shorter period of time may have been substantially higher. The Underlying Security’s annualized performance during this period was 21.41%. 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] | 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.

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] | 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.

Although Shares are listed on a national securities exchange, such as The Nasdaq Stock Market, LLC (the “Exchange”), and may be traded on U.S. exchanges other than the Exchange, there can be no assurance that 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. 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.

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 (the “Code”). As a RIC, the Fund will not be subject to U.S. federal income tax on the portion of its net investment income and net capital gain that it distributes to Shareholders, provided that it satisfies certain requirements of the Code. If the Fund does not qualify as a RIC for any taxable year and certain relief provisions are not available, the Fund’s taxable income will be subject to tax at the Fund level and to a further tax at the shareholder level when such income is distributed. To comply with the asset diversification test applicable to a RIC, the Fund will attempt to ensure that the value of 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] | 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] | HOOD Operational Risks. HOOD’s plans to venture into new products and services, as well as geographic expansion introduces significant uncertainties that may not yield desired outcomes. Operations are subject to complex and evolving laws, with non-compliance posing threats to HOOD’s business. Past and potential future regulatory investigations, settlements, and litigation could lead to substantial costs and reputational damage. Intense competition from rivals with greater resources threatens HOOD’s market position and revenue. Failure to retain existing customers or attract new ones, coupled with reduced usage of products and services, may result in declining revenue. Moreover, failure to develop and monetize innovative offerings could diminish competitiveness and revenue streams.
Dependence on complex software and systems entails the risk of interruptions, instability, and flaws, potentially disrupting operations. Reliance on third-party entities for critical functions exposes the company to risks associated with their performance. Additionally, incorporating AI technologies presents business, compliance, and reputational risks. Cybersecurity breaches targeting the company’s systems or customer data could lead to significant financial and reputational damage. Failure to maintain required net capital levels may result in restrictions and regulatory actions.
Risks associated with the effectiveness of compliance and risk management policies and procedures may impact operations under different market conditions. Operating in the highly volatile cryptocurrency market exposes the company to uncertainties and fluctuations affecting trading volumes and revenues.
Regulatory uncertainties surrounding cryptocurrency classification and compliance could lead to scrutiny, fines, and penalties. The complexity of rapidly evolving and difficult-to-interpret cryptocurrency laws and regulations poses challenges and compliance risks. Offering payment and spending services introduces risks related to illegal payments, customer asset loss, disputes, and liabilities. Future issuances of stock may lead to significant dilution, impacting shareholder value. Lastly, concentrated voting power with founders and multi-class stock structures limit shareholder influence over company decisions.
Factors that affect transaction-based revenue, such as reduced spreads in securities pricing, reduced levels of trading activity generally, changes in HOOD’s business relationships with or disruption in the services provided by market makers, and any new regulation of, or any bans on, payment for order flow, or “PFOF,” and similar practices, might result in reduced profitability, increased compliance costs, and negative publicity.

| 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 five-year period ended June 30, 2026 was 48.55%. The Underlying Security’s highest volatility rate for any one calendar year during this period was 75.22% and volatility for a shorter period of time may have been substantially higher. The Underlying Security’s annualized performance during this period was 53.57%. 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] | 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.

| 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.

Although Shares are listed on a national securities exchange, such as The Nasdaq Stock Market, LLC (the “Exchange”), and may be traded on U.S. exchanges other than the Exchange, there can be no assurance that 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. 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] | 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 (the “Code”). As a RIC, the Fund will not be subject to U.S. federal income tax on the portion of its net investment income and net capital gain that it distributes to Shareholders, provided that it satisfies certain requirements of the Code. If the Fund does not qualify as a RIC for any taxable year and certain relief provisions are not available, the Fund’s taxable income will be subject to tax at the Fund level and to a further tax at the shareholder level when such income is distributed. To comply with the asset diversification test applicable to a RIC, the Fund will attempt to ensure that the value of 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] | Business Risks. VST faces significant risks specific to its business operations, including exposure to fluctuations in wholesale power prices, fuel costs, and supply chain disruptions, which may adversely impact its revenues and financial performance. The company’s ability to manage commodity price risks is limited, and increased competition, regulatory changes, or government intervention in power markets could further challenge its profitability. Operating in a highly regulated industry, VST is subject to evolving environmental laws and climate change regulations that could impose substantial costs or constraints. Additionally, the capital-intensive nature of power generation, including the operation of the Comanche Peak nuclear facility, poses risks from cybersecurity threats, system failures, and extreme weather conditions. Changes in technology and energy efficiency initiatives could reduce electricity demand, impacting VST’s business model. The company also faces pressures from stakeholder expectations on environmental, social, and governance (ESG) issues, which may influence investor confidence and its stock performance. Further, litigation, legal proceedings, regulatory investigations or other administrative proceedings could expose VST to significant liabilities and reputational damage that could have a material adverse effect on VST.

| 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] | 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 of April 28, 2022 to June 30, 2026 (the maximum period available) was 128.12%. The Underlying Security’s highest volatility rate for any one calendar year during this period was 184.47% and volatility for a shorter period of time may have been substantially higher. The Underlying Security’s annualized performance during this period was -2.91%. 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] | 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.

| 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.

Although Shares are listed on a national securities exchange, such as The Nasdaq Stock Market, LLC (the “Exchange”), and may be traded on U.S. exchanges other than the Exchange, there can be no assurance that 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. 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] | 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.

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 (the “Code”). As a RIC, the Fund will not be subject to U.S. federal income tax on the portion of its net investment income and net capital gain that it distributes to Shareholders, provided that it satisfies certain requirements of the Code. If the Fund does not qualify as a RIC for any taxable year and certain relief provisions are not available, the Fund’s taxable income will be subject to tax at the Fund level and to a further tax at the shareholder level when such income is distributed. To comply with the asset diversification test applicable to a RIC, the Fund will attempt to ensure that the value of 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] | Business Risks. SOUN faces significant risks related to its financial condition and business operations, including a history of substantial net losses and negative cash flows, with no assurance of achieving profitability. The company’s reliance on a concentrated customer base exposes it to significant revenue risks if these relationships are disrupted. Competition in the rapidly evolving Voice AI (artificial intelligence) market, regulatory and legislative developments related to the use of AI and the potential inability to attract and retain key personnel further threaten its growth and operational stability. Additionally, cybersecurity incidents, interruptions in cloud services, and challenges in complying with complex domestic and international regulations could harm its business and client relationships.
Intellectual property risks include potential claims of infringement, unauthorized use of proprietary technology, and limitations imposed by open-source software usage exposing SOUN to significant litigation or licensing expenses or being prevented from selling SOUN’s products or making SOUN’s technologies available to its customers if such claims are successful. Governance risks stem from its dual-class stock structure, which concentrates voting control with Class B shareholders, limiting the influence of Class A shareholders. These governance dynamics, coupled with limited public company experience and identified material weaknesses in internal controls, may impact investor confidence. Tax-related risks, including limitations on the use of net operating loss carryforwards, add to the uncertainty surrounding SOUN’s financial outlook.

| 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] | SOUN Trading Risk. The trading price of SOUN may be subject to volatility and could experience wide fluctuations due to various factors. Short sellers may also play a significant role in trading SOUN, potentially affecting the supply and demand dynamics and contributing to market price volatility. Public perception and external factors beyond the company’s control may influence SOUN’s stock price disproportionately. Additionally, following periods of market volatility, companies have faced securities class action litigation. Any adverse judgment or future stockholder litigation could result in substantial costs and divert management’s attention and resources. In the event of a halt in trading of SOUN, trading in shares of related funds may be impacted, either temporarily or indefinitely. In particular, SOUN recently announced a delay in the filing of its annual financial statements, related to material weaknesses in SOUN’s internal control over financial reporting. This matter may contribute to increased volatility in the trading price of SOUN, and should the financial statements not be filed within required timelines, could result in SOUN stock being delisted.

| Risk [Text Block] | Software Industry Risks: The software industry can be significantly affected by intense competition, aggressive pricing, technological innovations, and product obsolescence. Companies in the software industry are subject to significant competitive pressures, such as aggressive pricing, new market entrants, competition for market share, short product cycles due to an accelerated rate of technological developments and the potential for limited earnings and/or falling profit margins. These companies also face the risks that new services, equipment or technologies will not be accepted by consumers and businesses or will become rapidly obsolete. These factors can affect the profitability of these companies and, as a result, the value of their securities. Also, patent protection is integral to the success of many companies in this industry, and profitability can be affected materially by, among other things, the cost of obtaining (or failing to obtain) patent approvals, the cost of litigating patent infringement and the loss of patent protection for products (which significantly increases pricing pressures and can materially reduce profitability with respect to such products). In addition, many software companies have limited operating histories. Prices of these companies’ securities historically have been more volatile than other securities, especially over the short term.

| 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 five-year period ended June 30, 2026 was 61.76%. The Underlying Security’s highest volatility rate for any one calendar year during this period was 72.10% and volatility for a shorter period of time may have been substantially higher. The Underlying Security’s annualized performance during this period was 38.53%. 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] | 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 intraday 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.

Although Shares are listed on a national securities exchange, such as The Nasdaq Stock Market, LLC (the “Exchange”), and may be traded on U.S. exchanges other than the Exchange, there can be no assurance that 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. 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.

| 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 (the “Code”). As a RIC, the Fund will not be subject to U.S. federal income tax on the portion of its net investment income and net capital gain that it distributes to Shareholders, provided that it satisfies certain requirements of the Code. If the Fund does not qualify as a RIC for any taxable year and certain relief provisions are not available, the Fund’s taxable income will be subject to tax at the Fund level and to a further tax at the shareholder level when such income is distributed. To comply with the asset diversification test applicable to a RIC, the Fund will attempt to ensure that the value of 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] | Business Risks. MRVL faces significant risks from macroeconomic and geopolitical factors, including economic downturns, inflation, rising interest rates, and trade restrictions with key markets such as China. Volatility in the semiconductor and technology sectors further adds to operational uncertainty, while reliance on a concentrated customer base exposes the company to potential disruptions from order cancellations or financial instability among major clients. The company’s ability to innovate in competitive markets such as 5G, cloud computing, and artificial intelligence is critical, but supply chain disruptions, including component shortages and extended lead times, could impair production and customer sales.
Operational challenges include maintaining a competitive cost structure while relying on third-party manufacturers and managing the integration of acquisitions to achieve anticipated synergies. MRVL also faces risks from intellectual property protection, particularly in international markets, and cybersecurity threats that could disrupt operations or compromise data. Environmental and regional risks, such as climate change and natural disasters in key operational areas like Taiwan and California, as well as potential litigation and disputes over contractual obligations, could further impact the company’s financial stability and operational performance.

| 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] | Semiconductors & Semiconductor Equipment Industry Risks. Competitive pressures may have a significant effect on the financial condition of semiconductor companies and, as product cycles shorten and manufacturing capacity increases, these companies may become increasingly subject to aggressive pricing, which hampers profitability. Reduced demand for end-user products, under-utilization of manufacturing capacity, and other factors could adversely impact the operating results of companies in the semiconductor sector. Semiconductor companies typically face high capital costs and may be heavily dependent on intellectual property rights. The semiconductor sector is highly cyclical, which may cause the operating results of many semiconductor companies to vary significantly. The industry is complex and global in nature, with manufacturing plants predominantly located in East Asia. Because of this, it is subject to numerous risks, including geopolitical tensions, earthquakes, and extreme weather events. The stock prices of companies in the semiconductor sector have been and likely will continue to be extremely volatile.

| 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 annualized historical volatility rate for the five-year period ended June 30, 2026 was 126.27%. The Underlying Security’s highest volatility rate for any one calendar year during this period was 175.63% and volatility for a shorter period of time may have been substantially higher. The Underlying Security’s annualized performance during this period was 14.74%. 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] | 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.

Although Shares are listed on a national securities exchange, such as The Nasdaq Stock Market, LLC (the “Exchange”), and may be traded on U.S. exchanges other than the Exchange, there can be no assurance that 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. 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] | 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 (the “Code”). As a RIC, the Fund will not be subject to U.S. federal income tax on the portion of its net investment income and net capital gain that it distributes to Shareholders, provided that it satisfies certain requirements of the Code. If the Fund does not qualify as a RIC for any taxable year and certain relief provisions are not available, the Fund’s taxable income will be subject to tax at the Fund level and to a further tax at the shareholder level when such income is distributed. To comply with the asset diversification test applicable to a RIC, the Fund will attempt to ensure that the value of 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] | Business Risks. RGTI faces significant financial and operational risks, including the need to raise additional capital when needed to sustain its research and development efforts. With a history of operating losses, limited revenue, and reliance on public sector contracts, the company is vulnerable to economic downturns, market volatility, and delays in achieving key milestones such as the commercialization of its quantum systems. Failure to scale operations or successfully integrate new technologies could further impede growth and profitability. Material weaknesses in financial reporting controls and risks associated with complex financial instruments add to potential investor concerns.
The quantum computing industry’s competitive and evolving nature presents challenges, with barriers such as the need for technological breakthroughs and dependence on cloud providers, third-party suppliers, and government contracts. RGTI’s ability to protect its intellectual property, adapt to stringent regulatory environments, and address supply chain disruptions is critical. Additional risks include international sales challenges, exposure to environmental and safety regulations, and susceptibility to litigation, cybersecurity threats, and product liability claims. These factors, alongside the nascent stage of the quantum computing industry, pose significant uncertainties for the company’s long-term success.

| 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] | Semiconductors & Semiconductor Equipment Industry Risks. Competitive pressures may have a significant effect on the financial condition of semiconductor companies and, as product cycles shorten and manufacturing capacity increases, these companies may become increasingly subject to aggressive pricing, which hampers profitability. Reduced demand for end-user products, under-utilization of manufacturing capacity, and other factors could adversely impact the operating results of companies in the semiconductor sector. Semiconductor companies typically face high capital costs and may be heavily dependent on intellectual property rights. The semiconductor sector is highly cyclical, which may cause the operating results of many semiconductor companies to vary significantly. The industry is complex and global in nature, with manufacturing plants predominantly located in East Asia. Because of this, it is subject to numerous risks, including geopolitical tensions, earthquakes, and extreme weather events. The stock prices of companies in the semiconductor sector have been and likely will continue to be extremely volatile.

| 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 annualized historical volatility rate for the five-year period ended June 30, 2026 was 87.67%. The Underlying Security’s highest volatility rate for any one calendar year during this period was 131.55%. The Underlying Security’s annualized performance during this period was 39.21%. 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] | 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. |

| 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.

| 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] | 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 The Nasdaq Stock Market, LLC (the “Exchange”), and may be traded on U.S. exchanges other than the Exchange, there can be no assurance that 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 RIC under Subchapter M of the Code. As a RIC, the Fund will not be subject to U.S. federal income tax on the portion of its net investment income and net capital gain that it distributes to shareholders, provided that it satisfies certain requirements of the Code. If the Fund does not qualify as a RIC for any taxable year and certain relief provisions are not available, the Fund’s taxable income will be subject to tax at the Fund level and to a further tax at the shareholder level when such income is distributed. To comply with the asset diversification test applicable to a RIC, the Fund will attempt to ensure that the value of 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] | 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] | 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 five-year period from May 1, 2021 to June 30, 2026 (the longest period available) was 125.79%. The Underlying Security’s highest volatility rate for any one calendar year during this period was 163.04% and volatility for a shorter period of time may have been substantially higher. The Underlying Security’s annualized performance during this period was 39.21 %. 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] | 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. |

| 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.

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

| 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.

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.

Although Shares are listed on a national securities exchange, such as The Nasdaq Stock Market, LLC (the “Exchange”), and may be traded on U.S. exchanges other than the Exchange, there can be no assurance that 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.

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 RIC under Subchapter M of the Code. As a RIC, the Fund will not be subject to U.S. federal income tax on the portion of its net investment income and net capital gain that it distributes to shareholders, provided that it satisfies certain requirements of the Code. If the Fund does not qualify as a RIC for any taxable year and certain relief provisions are not available, the Fund’s taxable income will be subject to tax at the Fund level and to a further tax at the shareholder level when such income is distributed. To comply with the asset diversification test applicable to a RIC, the Fund will attempt to ensure that the value of 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] | 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] | Quantum Computing Risk. Quantum computing companies may be significantly affected by intense competition, aggressive pricing dynamics, rapid technological advancements, and the risk of product obsolescence. Quantum computing companies face substantial competitive pressures, including competition for market share, the entry of new participants, and short innovation cycles driven by accelerated technological developments. These factors may result in limited earnings potential, declining profit margins, or both. Quantum computing companies are also exposed to the risk that their technologies, products, or services may fail to gain acceptance by consumers or businesses or may become rapidly outdated due to evolving advancements. The success of many quantum computing companies depends heavily on patent protection and intellectual property rights, making the cost of obtaining (or failing to obtain) patent approvals, litigating patent disputes, and the potential loss of patent protection critical factors affecting profitability. The expiration or invalidation of key patents can intensify pricing pressures and materially reduce profitability. Additionally, many companies in this sector have limited operating histories, adding to the uncertainty of their financial stability and long-term viability. Securities of quantum computing companies have historically demonstrated higher volatility compared to broader markets, particularly over shorter time frames, reflecting the speculative nature of the industry and the risks inherent in pioneering emerging technologies.

| Risk [Text Block] | Software Industry Risks. The software industry can be significantly affected by intense competition, aggressive pricing, technological innovations, and product obsolescence. Companies in the software industry are subject to significant competitive pressures, such as aggressive pricing, new market entrants, competition for market share, short product cycles due to an accelerated rate of technological developments and the potential for limited earnings and/or falling profit margins. These companies also face the risks that new services, equipment or technologies will not be accepted by consumers and businesses or will become rapidly obsolete. These factors can affect the profitability of these companies and, as a result, the value of their securities. Also, patent protection is integral to the success of many companies in this industry, and profitability can be affected materially by, among other things, the cost of obtaining (or failing to obtain) patent approvals, the cost of litigating patent infringement and the loss of patent protection for products (which significantly increases pricing pressures and can materially reduce profitability with respect to such products). In addition, many software companies have limited operating histories. Prices of these companies’ securities historically have been more volatile than other securities, especially over the short term.

QBTS has a history of losses and expects to incur significant expenses and continuing losses for the foreseeable future. QBTS has engaged in, and may in the future engage in, acquisitions of other companies. QBTS may not be successful in integrating such acquired companies which could impact its operations and share price.

| 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 June 30, 2026 was 25.06]%. The Underlying Security’s highest volatility rate for any one calendar year during this period was 33.74%. The Underlying Security’s annualized performance during this period was 12.45%. 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] | 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. |

| 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.

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] | 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.

| 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] | 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] | 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.

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 July 30, 2025 (the earliest date available) to June 30, 2026 was 158.72%. The Underlying Security’s annualized performance during this period was -11.32%. 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] | 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. |

| 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.

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] | 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 NYSE Arca, 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] | 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] | 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 annualized historical volatility rate for the period from November 16, 2021 (the earliest date available) to June 30, 2026 was 115.39%. The Underlying Security’s highest volatility rate for any one calendar year during this period was 123.80%. The Underlying Security’s annualized performance during this period was 10.30%. 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] | 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. |

| 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 NYSE Arca, 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.

| 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] | 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.

| 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] | 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.

Additional risks related to bitcoin include uncertainty surrounding new technology, limited evaluation due to bitcoin’s short trading history, and the potential decline in adoption and value over the long term. The extreme volatility of bitcoin’s price is also a risk factor. Regulatory uncertainties, such as potential government interventions and conflicting regulations across jurisdictions, can impact the demand for bitcoin and restrict its usage. Additionally, risks associated with the sale of newly mined bitcoin, bitcoin trading platforms, competition from alternative digital assets, mining operations, network modifications, and intellectual property claims pose further challenges to bitcoin-linked investments.

| 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.

| 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 June 30, 2026 was 67.83%. The Underlying Security’s highest volatility rate for any one calendar year during this period was 84.28%. The Underlying Security’s annualized performance during this period was 8.72%. 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] | 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. |

| 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.

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 NYSE Arca, 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] | 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] | 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.

The rare earth mining and processing and magnet manufacturing industry is capital intensive with competitive market dynamics. Production of REE and magnet products is dominated by Chinese competitors. These competitors may have greater financial resources, as well as other strategic advantages to operate, maintain, improve, and possibly expand their facilities. Additionally, MP’s Chinese competitors have historically been able to produce at relatively low costs due to domestic economic and regulatory factors, including less stringent environmental and governmental regulations and lower labor and benefit costs. If MP is not able to achieve consistent product quality at its anticipated costs of production, then any strategic advantages that MP’s competitors may have, including, without limitation, lower labor, compliance, and production costs, could have a material adverse effect on MP’s business.

| 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.

| 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 June 30, 2026 was 83.56%. The Underlying Security’s highest volatility rate for any one calendar year during this period was 90.90%. The Underlying Security’s annualized performance during this period was -23.70%. 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] | 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. |

| 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.

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] | 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 NYSE Arca, 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] | 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] | 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’s performance for periods greater than a trading day will be the result of each day’s returns compounded over the period, which is likely to differ from -200% of the Underlying Security’s performance, before fees and expenses. Compounding has a significant impact on funds that are inverse leveraged and that rebalance daily. The impact of compounding becomes more pronounced as volatility and holding periods increase and 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 the shareholder’s holding period of an investment in the Fund.
The chart below provides examples of how Underlying Security volatility could affect the Fund’s performance. Fund performance for periods greater than one single day can be estimated given any set of assumptions for the following factors: a) Underlying Security volatility; b) Underlying Security’s performance; c) period of time; d) financing rates associated with leveraged exposure; e) other Fund expenses; and f) the Underlying Security’s dividends. The chart below illustrates the impact of two principal factors – Underlying Security volatility and performance – on Fund performance. The chart shows estimated Fund returns for a number of combinations of Underlying Security volatility and performance over a one-year period. Performance shown in the chart assumes that (i) there were no Fund expenses; and (ii) borrowing rates (needed to obtain a leveraged short exposure) of 0%. If Fund expenses and/or actual borrowing/lending rates were reflected, the estimated returns would be lower than those shown. Particularly during periods where the Underlying Security experiences higher volatility, compounding will cause results for periods longer than a trading day to vary from -200% of the performance of the Underlying Security.
As shown in the chart below, the Fund would be expected to lose 17.10% if the Underlying Security provided no return over a one-year period during which the Underlying Security experienced annualized volatility of 25%. At higher ranges of volatility, there is a chance of a significant loss of value in the Fund, even if the Underlying Security return is flat.
For instance, if the Underlying Security’s annualized volatility is 100%, the Inverse Fund would be expected to lose 95% of its value, even if the cumulative Underlying Security’s return for the year was 0%. Areas shaded red (or dark gray) represent those scenarios where the Inverse Fund can be expected to return less than -200% of 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 -200% of the performance of the Underlying Security. The Inverse Fund’s actual returns may be significantly better or worse than the returns shown below as a result of any of the factors discussed above or in “Tracking Error Risk” below.
The Underlying Security’s annualized historical volatility rate for the five-year period ended June 30, 2026 was 109.39%. The Underlying Security’s highest volatility rate for any one calendar year during this period was 175.76%. The Underlying Security’s annualized performance during this period was 1.74%. 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 inverse correlation to the Underlying Security and therefore achieve its daily inverse investment objective. To achieve a high degree of 2 times inverse correlation with the Underlying Security, the Fund seeks to rebalance its portfolio daily to keep exposure consistent with its daily inverse investment objective. The possibility of the Fund being materially over-exposed (meaning providing more than -200% exposure to the Underlying Security – i.e., -201% or greater) or under-exposed (meaning providing less than -200% exposure to the Underlying Security – i.e., -199% or less) 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 2 times inverse 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 2 times inverse correlation to the Underlying Security.

| Risk [Text Block] | Short Sale Exposure Risk. The Fund will seek inverse or “short” exposure through financial instruments, which would cause the Fund to be exposed to certain risks associated with selling short. These risks include, under certain market conditions, an increase in the volatility and decrease in the liquidity of the instruments underlying the short position, which may lower the Fund’s return, result in a loss, have the effect of limiting the Fund’s ability to obtain inverse exposure through financial instruments, or require the Fund to seek inverse exposure through alternative investment strategies that may be less desirable or more costly to implement. To the extent that, at any particular point in time, the instruments underlying the short position may be thinly traded or have a limited market, including due to regulatory action, the Fund may be unable to meet its investment objective due to a lack of available securities or counterparties. During such periods, the Fund’s ability to issue additional Shares may be adversely affected. Obtaining inverse exposure through these instruments may be considered an aggressive investment technique. Any income, dividends or payments by any assets underlying the Fund’s short positions, if any, would negatively impact the Fund. The Fund could lose an amount greater than its net assets in the event the Underlying Security increases more than 50%.

| 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 value 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. If the Fund exceeds these regulatory thresholds, it may adjust its portfolio. These adjustments may cause the Fund to fail to achieve investment results, before fees and expenses, that correspond to -200% of the daily performance of the Underlying Security and may result in substantially lower returns during these periods. 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 inverse 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 inverse 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 inverse 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 value of the Underlying Security at the market close on the first trading day and the value of the Underlying Security at the time of purchase. If the Underlying Security declines in value, the Fund’s net assets will rise by the same amount as the Fund’s exposure. Conversely, if the Underlying Security gains in value, the Fund’s net assets will decline by the same 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 inverse 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.

Although Shares are listed on a national securities exchange, such as The Nasdaq Stock Market, LLC (the “Exchange”), and may be traded on U.S. exchanges other than the Exchange, there can be no assurance that 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. 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, such as market rules related to short sales, may prevent the Fund from limiting losses, realizing gains or achieving a high correlation with the Underlying 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] | 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 such exchanges as The Nasdaq Stock Market, LLC, 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 -2X 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] | Tax Risk. The Fund intends to elect and to qualify each year to be treated as a RIC under Subchapter M of the Code. As a RIC, the Fund will not be subject to U.S. federal income tax on the portion of its net investment income and net capital gain that it distributes to Shareholders, provided that it satisfies certain requirements of the Code. If the Fund does not qualify as a RIC for any taxable year and certain relief provisions are not available, the Fund’s taxable income will be subject to tax at the Fund level and to a further tax at the shareholder level when such income is distributed. To comply with the asset diversification test applicable to a RIC, the Fund will attempt to ensure that the value of 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] | Compounding and Market Volatility Risk. 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 likely to differ from -200% of the Underlying Security’s performance, before fees and expenses. Compounding has a significant impact on funds that are inverse leveraged and that rebalance daily. The impact of compounding becomes more pronounced as volatility and holding periods increase and 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 the shareholder’s holding period of an investment in the Fund.
The chart below provides examples of how Underlying Security volatility could affect the Fund’s performance. Fund performance for periods greater than one single day can be estimated given any set of assumptions for the following factors: a) Underlying Security volatility; b) Underlying Security’s performance; c) period of time; d) financing rates associated with leveraged exposure; e) other Fund expenses; and f) the Underlying Security’s dividends. The chart below illustrates the impact of two principal factors – Underlying Security volatility and performance – on Fund performance. The chart shows estimated Fund returns for a number of combinations of Underlying Security volatility and performance over a one-year period. Performance shown in the chart assumes that (i) there were no Fund expenses; and (ii) borrowing rates (needed to obtain a leveraged short exposure) of 0%. If Fund expenses and/or actual borrowing/lending rates were reflected, the estimated returns would be lower than those shown. Particularly during periods where the Underlying Security experiences higher volatility, compounding will cause results for periods longer than a trading day to vary from -200% of the performance of the Underlying Security.
As shown in the chart below, the Fund would be expected to lose 17.10% if the Underlying Security provided no return over a one-year period during which the Underlying Security experienced annualized volatility of 25%. At higher ranges of volatility, there is a chance of a significant loss of value in the Fund, even if the Underlying Security return is flat.
For instance, if the Underlying Security’s annualized volatility is 100%, the Inverse Fund would be expected to lose 95% of its value, even if the cumulative Underlying Security’s return for the year was 0%. Areas shaded red (or dark gray) represent those scenarios where the Inverse Fund can be expected to return less than -200% of 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 -200% of the performance of the Underlying Security. The Inverse Fund’s actual returns may be significantly better or worse than the returns shown below as a result of any of the factors discussed above or in “Tracking Error Risk” below.
The Underlying Security’s annualized historical volatility rate for the five-year period ended June 30, 2026 was 99.29%. The Underlying Security’s highest volatility rate for any one calendar year during this period was 126.05% . The Underlying Security’s annualized performance during this period was 37.85%. Historical volatility and performance are not indications of what the Underlying Security volatility and performance will be in the future. The volatility of instruments that reflect the value of the Underlying Security, such as swaps, may differ from the volatility of the Underlying Security.

The possibility of the Fund being materially over-exposed (meaning providing more than -200% exposure to the Underlying Security – i.e., -201% or greater) or under-exposed (meaning providing less than -200% exposure to the Underlying Security – i.e., -199% or less) 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 2 times inverse 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 2 times inverse correlation to the Underlying Security.

| Risk [Text Block] | Short Sale Exposure Risk. The Fund will seek inverse or “short” exposure through financial instruments, which would cause the Fund to be exposed to certain risks associated with selling short. These risks include, under certain market conditions, an increase in the volatility and decrease in the liquidity of the instruments underlying the short position, which may lower the Fund’s return, result in a loss, have the effect of limiting the Fund’s ability to obtain inverse exposure through financial instruments, or require the Fund to seek inverse exposure through alternative investment strategies that may be less desirable or more costly to implement. To the extent that, at any particular point in time, the instruments underlying the short position may be thinly traded or have a limited market, including due to regulatory action, the Fund may be unable to meet its investment objective due to a lack of available securities or counterparties. During such periods, the Fund’s ability to issue additional Shares may be adversely affected. Obtaining inverse exposure through these instruments may be considered an aggressive investment technique. Any income, dividends or payments by any assets underlying the Fund’s short positions, if any, would negatively impact the Fund. The Fund could lose an amount greater than its net assets in the event the Underlying Security increases more than 50%.

| 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 value 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. If the Fund exceeds these regulatory thresholds, it may adjust its portfolio. These adjustments may cause the Fund to fail to achieve investment results, before fees and expenses, that correspond to -200% of the daily performance of the Underlying Security and may result in substantially lower returns during these periods. 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 inverse 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 inverse 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 inverse 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 value of the Underlying Security at the market close on the first trading day and the value of the Underlying Security at the time of purchase. If the Underlying Security declines in value, the Fund’s net assets will rise by the same amount as the Fund’s exposure. Conversely, if the Underlying Security gains in value, the Fund’s net assets will decline by the same 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 inverse 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.

| Risk [Text Block] | Trading. Although Shares are listed on a national securities exchange, such as The Nasdaq Stock Market, LLC (the “Exchange”), and may be traded on U.S. exchanges other than the Exchange, there can be no assurance that 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. 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, such as market rules related to short sales, may prevent the Fund from limiting losses, realizing gains or achieving a high correlation with the Underlying 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] | 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 such exchanges as The Nasdaq Stock Market, LLC, 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.

Tracking error is the divergence of the Fund’s performance from that of its investment objective which aims to replicate -2X 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 RIC under Subchapter M of the Code. As a RIC, the Fund will not be subject to U.S. federal income tax on the portion of its net investment income and net capital gain that it distributes to Shareholders, provided that it satisfies certain requirements of the Code. If the Fund does not qualify as a RIC for any taxable year and certain relief provisions are not available, the Fund’s taxable income will be subject to tax at the Fund level and to a further tax at the shareholder level when such income is distributed. To comply with the asset diversification test applicable to a RIC, the Fund will attempt to ensure that the value of 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.

| 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.

| 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 the company has strong earnings reports, or provides positive future guidance, dividend increases, share buybacks, or engages in strategic acquisitions and product launches. Additionally, the Fund will seek to employ its investment strategy as it relates to the underlying issuer regardless of whether there are favorable industry trends, regulatory approvals, analyst upgrades, strategic partnerships, debt reduction, or improved economic conditions.

| Prospectus [Line Items] | |||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||
| Risk [Text Block] | Compounding and Market Volatility Risk. 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 likely to differ from -200% of the Underlying Security’s performance, before fees and expenses. Compounding has a significant impact on funds that are inverse leveraged and that rebalance daily. The impact of compounding becomes more pronounced as volatility and holding periods increase and 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 the shareholder’s holding period of an investment in the Fund.
The chart below provides examples of how Underlying Security volatility could affect the Fund’s performance. Fund performance for periods greater than one single day can be estimated given any set of assumptions for the following factors: a) Underlying Security volatility; b) Underlying Security’s performance; c) period of time; d) financing rates associated with leveraged exposure; e) other Fund expenses; and f) the Underlying Security’s dividends. The chart below illustrates the impact of two principal factors – Underlying Security volatility and performance – on Fund performance. The chart shows estimated Fund returns for a number of combinations of Underlying Security volatility and performance over a one-year period. Performance shown in the chart assumes that (i) there were no Fund expenses; and (ii) borrowing rates (needed to obtain a leveraged short exposure) of 0%. If Fund expenses and/or actual borrowing/lending rates were reflected, the estimated returns would be lower than those shown. Particularly during periods where the Underlying Security experiences higher volatility, compounding will cause results for periods longer than a trading day to vary from -200% of the performance of the Underlying Security.
As shown in the chart below, the Fund would be expected to lose 17.10% if the Underlying Security provided no return over a one-year period during which the Underlying Security experienced annualized volatility of 25%. At higher ranges of volatility, there is a chance of a significant loss of value in the Fund, even if the Underlying Security return is flat.
For instance, if the Underlying Security’s annualized volatility is 100%, the Inverse Fund would be expected to lose 95% of its value, even if the cumulative Underlying Security’s return for the year was 0%. Areas shaded red (or dark gray) represent those scenarios where the Inverse Fund can be expected to return less than -200% of 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 -200% of the performance of the Underlying Security. The Inverse Fund’s actual returns may be significantly better or worse than the returns shown below as a result of any of the factors discussed above or in “Tracking Error Risk” below.
The Underlying Security’s annualized historical volatility rate for the five-year period ended June 30, 2026 was 34.63%. The Underlying Security’s highest volatility rate for any one calendar year during this period was 71.11%. The Underlying Security’s annualized performance during this period was 34.63%. 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 inverse correlation to the Underlying Security and therefore achieve its daily inverse investment objective. To achieve a high degree of 2 times inverse correlation with the Underlying Security, the Fund seeks to rebalance its portfolio daily to keep exposure consistent with its daily inverse investment objective. The possibility of the Fund being materially over-exposed (meaning providing more than -200% exposure to the Underlying Security – i.e., -201% or greater) or under-exposed (meaning providing less than -200% exposure to the Underlying Security – i.e., -199% or less) 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 2 times inverse 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 2 times inverse correlation to the Underlying Security.

| Prospectus [Line Items] | |||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||
| Risk [Text Block] | Short Sale Exposure Risk. The Fund will seek inverse or “short” exposure through financial instruments, which would cause the Fund to be exposed to certain risks associated with selling short. These risks include, under certain market conditions, an increase in the volatility and decrease in the liquidity of the instruments underlying the short position, which may lower the Fund’s return, result in a loss, have the effect of limiting the Fund’s ability to obtain inverse exposure through financial instruments, or require the Fund to seek inverse exposure through alternative investment strategies that may be less desirable or more costly to implement. To the extent that, at any particular point in time, the instruments underlying the short position may be thinly traded or have a limited market, including due to regulatory action, the Fund may be unable to meet its investment objective due to a lack of available securities or counterparties. During such periods, the Fund’s ability to issue additional Shares may be adversely affected. Obtaining inverse exposure through these instruments may be considered an aggressive investment technique. Any income, dividends or payments by any assets underlying the Fund’s short positions, if any, would negatively impact the Fund. The Fund could lose an amount greater than its net assets in the event the Underlying Security increases more than 50%.

| 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 value 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. If the Fund exceeds these regulatory thresholds, it may adjust its portfolio. These adjustments may cause the Fund to fail to achieve investment results, before fees and expenses, that correspond to -200% of the daily performance of the Underlying Security and may result in substantially lower returns during these periods. 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 inverse performance for the Fund.
In addition, the Fund’s investments in derivatives are subject to the following risks:
|

| Defiance Daily Target 2X Short PLTR ETF | Swap Agreements [Member] | |||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||
| 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 inverse 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 inverse 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 value of the Underlying Security at the market close on the first trading day and the value of the Underlying Security at the time of purchase. If the Underlying Security declines in value, the Fund’s net assets will rise by the same amount as the Fund’s exposure. Conversely, if the Underlying Security gains in value, the Fund’s net assets will decline by the same 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 inverse 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 The Nasdaq Stock Market, LLC (the “Exchange”), and may be traded on U.S. exchanges other than the Exchange, there can be no assurance that 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. 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, such as market rules related to short sales, may prevent the Fund from limiting losses, realizing gains or achieving a high correlation with the Underlying 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] | 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 such exchanges as The Nasdaq Stock Market, LLC, 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 -2X 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 RIC under Subchapter M of the Code. As a RIC, the Fund will not be subject to U.S. federal income tax on the portion of its net investment income and net capital gain that it distributes to Shareholders, provided that it satisfies certain requirements of the Code. If the Fund does not qualify as a RIC for any taxable year and certain relief provisions are not available, the Fund’s taxable income will be subject to tax at the Fund level and to a further tax at the shareholder level when such income is distributed. To comply with the asset diversification test applicable to a RIC, the Fund will attempt to ensure that the value of 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] | PLTR Price Appreciation Risk. As part of the Fund’s inverse investment strategy, the Fund purchases and sells swap contracts and options contracts that are based on the share price of PLTR common stock (the “Underlying Security”). This strategy subjects the Fund to certain of the same risks as if it shorted shares of the Underlying Security, even though it does not. By virtue of the Fund’s indirect -2X exposure to changes in the share price of the Underlying Security, the Fund is subject to the risk that the Underlying Security’s share price increases. If the share price of the Underlying Security increases, the Fund will likely lose value and, as a result, the Fund may suffer significant losses. The Fund may also be subject to the following risks:

| Prospectus [Line Items] | |||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||
| Risk [Text Block] | Compounding and Market Volatility Risk. 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 likely to differ from -200% of the Underlying Security’s performance, before fees and expenses. Compounding has a significant impact on funds that are inverse leveraged and that rebalance daily. The impact of compounding becomes more pronounced as volatility and holding periods increase and 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 the shareholder’s holding period of an investment in the Fund.
The chart below provides examples of how Underlying Security volatility could affect the Fund’s performance. Fund performance for periods greater than one single day can be estimated given any set of assumptions for the following factors: a) Underlying Security volatility; b) Underlying Security’s performance; c) period of time; d) financing rates associated with leveraged exposure; e) other Fund expenses; and f) the Underlying Security’s dividends. The chart below illustrates the impact of two principal factors – Underlying Security volatility and performance – on Fund performance. The chart shows estimated Fund returns for a number of combinations of Underlying Security volatility and performance over a one-year period. Performance shown in the chart assumes that (i) there were no Fund expenses; and (ii) borrowing rates (needed to obtain a leveraged short exposure) of 0%. If Fund expenses and/or actual borrowing/lending rates were reflected, the estimated returns would be lower than those shown. Particularly during periods where the Underlying Security experiences higher volatility, compounding will cause results for periods longer than a trading day to vary from -200% of the performance of the Underlying Security.
As shown in the chart below, the Fund would be expected to lose 17.10% if the Underlying Security provided no return over a one-year period during which the Underlying Security experienced annualized volatility of 25%. At higher ranges of volatility, there is a chance of a significant loss of value in the Fund, even if the Underlying Security return is flat.
For instance, if the Underlying Security’s annualized volatility is 100%, the Inverse Fund would be expected to lose 95% of its value, even if the cumulative Underlying Security’s return for the year was 0%. Areas shaded red (or dark gray) represent those scenarios where the Inverse Fund can be expected to return less than -200% of 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 -200% of the performance of the Underlying Security. The Inverse Fund’s actual returns may be significantly better or worse than the returns shown below as a result of any of the factors discussed above or in “Tracking Error Risk” below.
The Underlying Security’s annualized historical volatility rate for the five-year period ended June 30, 2026 was 79.43%. The Underlying Security’s highest volatility rate for any one calendar year during this period was 91.57%. The Underlying Security’s annualized performance during this period was 56.28%. 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 inverse correlation to the Underlying Security and therefore achieve its daily inverse investment objective. To achieve a high degree of 2 times inverse correlation with the Underlying Security, the Fund seeks to rebalance its portfolio daily to keep exposure consistent with its daily inverse investment objective. The possibility of the Fund being materially over-exposed (meaning providing more than -200% exposure to the Underlying Security – i.e., -201% or greater) or under-exposed (meaning providing less than -200% exposure to the Underlying Security – i.e., -199% or less) 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 2 times inverse 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 2 times inverse correlation to the Underlying Security.

| Risk [Text Block] | Short Sale Exposure Risk. The Fund will seek inverse or “short” exposure through financial instruments, which would cause the Fund to be exposed to certain risks associated with selling short. These risks include, under certain market conditions, an increase in the volatility and decrease in the liquidity of the instruments underlying the short position, which may lower the Fund’s return, result in a loss, have the effect of limiting the Fund’s ability to obtain inverse exposure through financial instruments, or require the Fund to seek inverse exposure through alternative investment strategies that may be less desirable or more costly to implement. To the extent that, at any particular point in time, the instruments underlying the short position may be thinly traded or have a limited market, including due to regulatory action, the Fund may be unable to meet its investment objective due to a lack of available securities or counterparties. During such periods, the Fund’s ability to issue additional Shares may be adversely affected. Obtaining inverse exposure through these instruments may be considered an aggressive investment technique. Any income, dividends or payments by any assets underlying the Fund’s short positions, if any, would negatively impact the Fund. The Fund could lose an amount greater than its net assets in the event the Underlying Security increases more than 50%.

| 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 value 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. If the Fund exceeds these regulatory thresholds, it may adjust its portfolio. These adjustments may cause the Fund to fail to achieve investment results, before fees and expenses, that correspond to -200% of the daily performance of the Underlying Security and may result in substantially lower returns during these periods. 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 inverse 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 inverse 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 inverse 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 value of the Underlying Security at the market close on the first trading day and the value of the Underlying Security at the time of purchase. If the Underlying Security declines in value, the Fund’s net assets will rise by the same amount as the Fund’s exposure. Conversely, if the Underlying Security gains in value, the Fund’s net assets will decline by the same 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 inverse 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.

| 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 The Nasdaq Stock Market, LLC (the “Exchange”), and may be traded on U.S. exchanges other than the Exchange, there can be no assurance that 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. 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, such as market rules related to short sales, may prevent the Fund from limiting losses, realizing gains or achieving a high correlation with the Underlying 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] | 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 such exchanges as The Nasdaq Stock Market, LLC, 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.

| Prospectus [Line Items] | |||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||
| 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 -2X 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. 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 Funds own shares.”

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.

| 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] | 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.

| 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 RIC under Subchapter M of the Code. As a RIC, the Fund will not be subject to U.S. federal income tax on the portion of its net investment income and net capital gain that it distributes to Shareholders, provided that it satisfies certain requirements of the Code. If the Fund does not qualify as a RIC for any taxable year and certain relief provisions are not available, the Fund’s taxable income will be subject to tax at the Fund level and to a further tax at the shareholder level when such income is distributed. To comply with the asset diversification test applicable to a RIC, the Fund will attempt to ensure that the value of 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] | RKLB Price Appreciation Risk. As part of the Fund’s inverse investment strategy, the Fund purchases and sells swap contracts and options contracts that are based on the share price of RKLB common stock (the “Underlying Security”). This strategy subjects the Fund to certain of the same risks as if it shorted shares of the Underlying Security, even though it does not. By virtue of the Fund’s indirect -2X exposure to changes in the share price of the Underlying Security, the Fund is subject to the risk that the Underlying Security’s share price increases. If the share price of the Underlying Security increases, the Fund will likely lose value and, as a result, the Fund may suffer significant losses. The Fund may also be subject to the following risks:

| 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.
