| Risk [Text Block] | ALAB Risks. The Fund invests in swap contracts and options that are based on the share price of ALAB. This subjects the Fund to certain of the same risks as if it owned shares of ALAB, even though it does not. By virtue of the Fund’s investments in swap contracts and options that are based on the value of ALAB, 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 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 March 20, 2024 to June 30, 2026 (the longest period available) was 92.32%. The Underlying Security’s highest volatility rate for any one calendar year during this period was 90.74%. The Underlying Security’s annualized performance during this period was -59.36%. Historical Underlying Security volatility and performance are not indications of what Underlying Security volatility and performance will be in the future.

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

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

| Risk [Text Block] | Derivatives Risk. Derivatives are financial instruments that derive value from the underlying reference asset or assets, such as stocks, bonds, or funds (including ETFs), interest rates or indexes. The Fund’s investments in derivatives may pose risks in addition to, and greater than, those associated with directly investing in securities or other ordinary investments, including risk related to the market, leverage, imperfect daily correlations with underlying investments or the Fund’s other portfolio holdings, higher price volatility, lack of availability, counterparty risk, liquidity, valuation and legal restrictions. The use of derivatives is a highly specialized activity that involves investment techniques and risks different from those associated with ordinary portfolio securities transactions. The use of derivatives may result in larger losses or smaller gains than directly investing in securities. When the Fund uses derivatives, there may be imperfect correlation between the share price of the Underlying Security and the derivative, which may prevent the Fund from achieving its investment objective. Because derivatives often require only a limited initial investment, the use of derivatives may expose the Fund to losses in excess of those amounts initially invested.
The Fund will be subject to regulatory constraints relating to level of value at risk that the Fund may incur through its derivative portfolio. To the extent the Fund exceeds these regulatory thresholds over an extended period, the Fund may determine that it is necessary to make adjustments to the Fund’s investment strategy, including the desired daily leveraged performance for the Fund. |

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

| Prospectus [Line Items] | |||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||
| Risk [Text Block] | Options Contracts. The use of options contracts involves investment strategies and risks different from those associated with ordinary portfolio securities transactions. The prices of options are volatile and are influenced by, among other things, actual and anticipated changes in the value of the underlying instrument, including the anticipated volatility, which are affected by fiscal and monetary policies and by national and international political, changes in the actual or implied volatility or the reference asset, the time remaining until the expiration of the option contract and economic events. The value of the options contracts in which the Fund invests are substantially influenced by the value of the Underlying Security. The Fund may experience substantial downside from specific option positions and certain option positions held by the Fund may expire worthless. The options held by the Fund are exercisable at the strike price on their expiration date. As an option approaches its expiration date, its value typically increasingly moves with the value of the underlying instrument. However, prior to such date, the value of an option generally does not increase or decrease at the same rate as the underlying instrument. There may at times be an imperfect correlation between the movement in values options contracts and the underlying instrument, and there may at times not be a liquid secondary market for certain options contracts. The value of the options held by the Fund will be determined based on market quotations or other recognized pricing methods. Additionally, as the Fund intends to continuously maintain indirect exposure to the Underlying Security through the use of options contracts, as the options contracts it holds are exercised or expire it will enter into new options contracts, a practice referred to as “rolling.” If the expiring options contracts do not generate proceeds enough to cover the cost of entering into new options contracts, the Fund may experience losses. The use of options to generate leverage introduces additional risks, including significant potential losses if the market moves unfavorably. The leverage inherent in options can amplify both gains and losses, leading to increased volatility and potential for substantial losses, particularly in periods of market uncertainty or low liquidity. Additionally, the Fund may incur losses if the value of the Underlying Security moves against its positions, potentially resulting in a complete loss of the premium paid.

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

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

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

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

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

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

| Risk [Text Block] | Trading. Although Shares are listed on a national securities exchange, such as 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.

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

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

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

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

| Risk [Text Block] | Tax Risk. The Fund intends to elect and to qualify each year to be treated as a regulated investment company (a “RIC”) under Subchapter M of the Internal Revenue Code of 1986, as amended (“Code”). As a RIC, the Fund will not be subject to U.S. federal income tax on the portion of its net investment income and net capital gain that it distributes to shareholders, provided that it satisfies certain requirements of the Code. If the Fund does not qualify as a RIC for any taxable year and certain relief provisions are not available, the Fund’s taxable income will be subject to tax at the Fund level and to a further tax at the shareholder level when such income is distributed. To comply with the asset diversification test applicable to a RIC, the Fund will attempt to ensure that the value of swap contracts and options on shares of a single issuer does not exceed 25% of the Fund’s value at the close of any quarter. If the value of swap contracts and options on shares of a single issuer were to exceed 25% of the Fund’s total assets at the end of a tax quarter, the Fund, generally, has a grace period to cure such lack of compliance. If the Fund fails to timely cure, it may no longer be eligible to be treated as a RIC.

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

| Prospectus [Line Items] | |||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||
| Risk [Text Block] | Compounding and Market Volatility Risk. The Fund has a daily leveraged investment objective and the Fund’s performance for periods greater than a trading day will be the result of each day’s returns compounded over the period, which is very likely to differ from two times (200%) the Underlying Security’s performance, before the Fund’s management fee and other expenses. Compounding affects all investments but has a more significant impact on funds that aim to replicate leveraged daily returns and that rebalance daily. For the Fund aiming to replicate two times the daily performance of an Underlying Security, if adverse daily performance of the Underlying Security reduces the amount of a shareholder’s investment, any further adverse daily performance will lead to a smaller dollar loss because the shareholder’s investment had already been reduced by the prior adverse performance. Equally, however, if favorable daily performance of the Underlying Security increases the amount of a shareholder’s investment, the dollar amount lost due to future adverse performance will increase because the shareholder’s investment has increased.
The effect of compounding becomes more pronounced as the Underlying Security’s volatility and the holding period increase. The impact of compounding will impact each shareholder differently depending on the period of time an investment in the Fund is held and the volatility of the Underlying Security during a shareholder’s holding period of an investment in the Fund.
The chart below provides examples of how the Underlying Security’s volatility could affect the Fund’s performance. The chart illustrates the impact of two factors that affect the Fund’s performance – the Underlying Security’s volatility and the Underlying Security’s performance. The Underlying Security’s performance shows the percentage change in the share price of the Underlying Security over the specified time period, while the Underlying Security’s volatility is a statistical measure of the magnitude of fluctuations in the returns during that time period. As illustrated below, even if the Underlying Security’s performance over two equal time periods is identical, different Underlying Security volatility (i.e., in magnitude of fluctuations in the share price of the Underlying Security) during the two time periods could result in drastically different Fund performance for the two time periods because of compounding daily returns during the time periods.
Fund performance for periods greater than one single day can be estimated given any set of assumptions for the following factors: a) the Underlying Security volatility; b) the Underlying Security performance; c) period of time; d) financing rates associated with leveraged exposure; and e) other Fund expenses. The chart shows estimated Fund returns for a number of combinations of Underlying Security volatility and Underlying Security performance over a one-year period. Performance shown in the chart assumes that: (i) there were no Fund expenses; (ii) borrowing/lending rates (to obtain leveraged exposure) of 0%. If Fund expenses and/or actual borrowing/lending rates were reflected the estimated returns would be different than those shown. Particularly during periods of higher Underlying Security volatility, compounding will cause results for periods longer than a trading day to vary from two times (200%) the performance of the Underlying Security.
As shown in the chart below, the Fund would be expected to lose 6.1% if there was no change in the share price of the Underlying Security over a one-year period during which the Underlying Security experienced annualized volatility of 25%. If the Underlying Security’s annualized volatility were to rise to 75%, the hypothetical loss for a one-year period would widen to approximately -43%. At higher ranges of volatility, there is a chance of a significant loss of value in the Fund, even if there were no change in the share price of the Underlying Security. For instance, if the Underlying Security’s annualized volatility is 100%, the Fund would be expected to lose 63.2% of its value, even if the cumulative Underlying Security change in the share price of the Underlying Security for the year was 0%.
Areas shaded red (or dark gray) represent those scenarios where the Fund can be expected to return less than two times (200%) the performance of the Underlying Security and those shaded green (or light gray) represent those scenarios where the Fund can be expected to return more than two times (200%) the performance of the Underlying Security. The Fund’s actual performance may be significantly better or worse than the performance shown below as a result of any of the factors discussed above or in the “Daily Correlation/Tracking Risk” below.
The Underlying Security’s annualized historical volatility rate for the five-year period ended June 30, 2026 was 139.63%. The Underlying Security’s highest volatility rate for any one calendar year during this period was 190.0%. The Underlying Security’s annualized performance during this period was 28.69%. Historical Underlying Security volatility and performance are not indications of what Underlying Security volatility and performance will be in the future.

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

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

| Risk [Text Block] | Derivatives Risk. Derivatives are financial instruments that derive value from the underlying reference asset or assets, such as stocks, bonds, or funds (including ETFs), interest rates or indexes. The Fund’s investments in derivatives may pose risks in addition to, and greater than, those associated with directly investing in securities or other ordinary investments, including risk related to the market, leverage, imperfect daily correlations with underlying investments or the Fund’s other portfolio holdings, higher price volatility, lack of availability, counterparty risk, liquidity, valuation and legal restrictions. The use of derivatives is a highly specialized activity that involves investment techniques and risks different from those associated with ordinary portfolio securities transactions. The use of derivatives may result in larger losses or smaller gains than directly investing in securities. When the Fund uses derivatives, there may be imperfect correlation between the share price of the Underlying Security and the derivative, which may prevent the Fund from achieving its investment objective. Because derivatives often require only a limited initial investment, the use of derivatives may expose the Fund to losses in excess of those amounts initially invested.
The Fund will be subject to regulatory constraints relating to level of value at risk that the Fund may incur through its derivative portfolio. To the extent the Fund exceeds these regulatory thresholds over an extended period, the Fund may determine that it is necessary to make adjustments to the Fund’s investment strategy, including the desired daily leveraged performance for the Fund. |

| 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.

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

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

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

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

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

| Risk [Text Block] | Tax Risk. The Fund intends to elect and to qualify each year to be treated as a regulated investment company (a “RIC”) under Subchapter M of the Internal Revenue Code of 1986, as amended (“Code”). As a RIC, the Fund will not be subject to U.S. federal income tax on the portion of its net investment income and net capital gain that it distributes to shareholders, provided that it satisfies certain requirements of the Code. If the Fund does not qualify as a RIC for any taxable year and certain relief provisions are not available, the Fund’s taxable income will be subject to tax at the Fund level and to a further tax at the shareholder level when such income is distributed. To comply with the asset diversification test applicable to a RIC, the Fund will attempt to ensure that the value of swap contracts and options on shares of a single issuer does not exceed 25% of the Fund’s value at the close of any quarter. If the value of swap contracts and options on shares of a single issuer were to exceed 25% of the Fund’s total assets at the end of a tax quarter, the Fund, generally, has a grace period to cure such lack of compliance. If the Fund fails to timely cure, it may no longer be eligible to be treated as a RIC.

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

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 five-year period ended June 30, 2026 was 117.79%. The Underlying Security’s highest volatility rate for any one calendar year during this period was 241.85%. The Underlying Security’s annualized performance during this period was 10.50%. Historical Underlying Security volatility and performance are not indications of what Underlying Security volatility and performance will be in the future.

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

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

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 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.

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

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

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

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

| Risk [Text Block] | Tax Risk. The Fund intends to elect and to qualify each year to be treated as a regulated investment company (a “RIC”) under Subchapter M of the Internal Revenue Code of 1986, as amended (“Code”). As a RIC, the Fund will not be subject to U.S. federal income tax on the portion of its net investment income and net capital gain that it distributes to shareholders, provided that it satisfies certain requirements of the Code. If the Fund does not qualify as a RIC for any taxable year and certain relief provisions are not available, the Fund’s taxable income will be subject to tax at the Fund level and to a further tax at the shareholder level when such income is distributed. To comply with the asset diversification test applicable to a RIC, the Fund will attempt to ensure that the value of swap contracts and options on shares of a single issuer does not exceed 25% of the Fund’s value at the close of any quarter. If the value of swap contracts and options on shares of a single issuer were to exceed 25% of the Fund’s total assets at the end of a tax quarter, the Fund, generally, has a grace period to cure such lack of compliance. If the Fund fails to timely cure, it may no longer be eligible to be treated as a RIC.

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

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

| Prospectus [Line Items] | |||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||
| Risk [Text Block] | Compounding and Market Volatility Risk. The Fund has a daily leveraged investment objective and the Fund’s performance for periods greater than a trading day will be the result of each day’s returns compounded over the period, which is very likely to differ from two times (200%) the Underlying Security’s performance, before the Fund’s management fee and other expenses. Compounding affects all investments but has a more significant impact on funds that aim to replicate leveraged daily returns and that rebalance daily. For the Fund aiming to replicate two times the daily performance of an Underlying Security, if adverse daily performance of the Underlying Security reduces the amount of a shareholder’s investment, any further adverse daily performance will lead to a smaller dollar loss because the shareholder’s investment had already been reduced by the prior adverse performance. Equally, however, if favorable daily performance of the Underlying Security increases the amount of a shareholder’s investment, the dollar amount lost due to future adverse performance will increase because the shareholder’s investment has increased.
The effect of compounding becomes more pronounced as the Underlying Security’s volatility and the holding period increase. The impact of compounding will impact each shareholder differently depending on the period of time an investment in the Fund is held and the volatility of the Underlying Security during a shareholder’s holding period of an investment in the Fund.
The chart below provides examples of how the Underlying Security’s volatility could affect the Fund’s performance. The chart illustrates the impact of two factors that affect the Fund’s performance – the Underlying Security’s volatility and the Underlying Security’s performance. The Underlying Security’s performance shows the percentage change in the share price of the Underlying Security over the specified time period, while the Underlying Security’s volatility is a statistical measure of the magnitude of fluctuations in the returns during that time period. As illustrated below, even if the Underlying Security’s performance over two equal time periods is identical, different Underlying Security volatility (i.e., in magnitude of fluctuations in the share price of the Underlying Security) during the two time periods could result in drastically different Fund performance for the two time periods because of compounding daily returns during the time periods.
Fund performance for periods greater than one single day can be estimated given any set of assumptions for the following factors: a) the Underlying Security volatility; b) the Underlying Security performance; c) period of time; d) financing rates associated with leveraged exposure; and e) other Fund expenses. The chart shows estimated Fund returns for a number of combinations of Underlying Security volatility and Underlying Security performance over a one-year period. Performance shown in the chart assumes that: (i) there were no Fund expenses; (ii) borrowing/lending rates (to obtain leveraged exposure) of 0%. If Fund expenses and/or actual borrowing/lending rates were reflected the estimated returns would be different than those shown. Particularly during periods of higher Underlying Security volatility, compounding will cause results for periods longer than a trading day to vary from two times (200%) the performance of the Underlying Security.
As shown in the chart below, the Fund would be expected to lose 6.1% if there was no change in the share price of the Underlying Security over a one-year period during which the Underlying Security experienced annualized volatility of 25%. If the Underlying Security’s annualized volatility were to rise to 75%, the hypothetical loss for a one-year period would widen to approximately -43%. At higher ranges of volatility, there is a chance of a significant loss of value in the Fund, even if there were no change in the share price of the Underlying Security. For instance, if the Underlying Security’s annualized volatility is 100%, the Fund would be expected to lose 63.2% of its value, even if the cumulative Underlying Security change in the share price of the Underlying Security for the year was 0%.
Areas shaded red (or dark gray) represent those scenarios where the Fund can be expected to return less than two times (200%) the performance of the Underlying Security and those shaded green (or light gray) represent those scenarios where the Fund can be expected to return more than two times (200%) the performance of the Underlying Security. The Fund’s actual performance may be significantly better or worse than the performance shown below as a result of any of the factors discussed above or in the “Daily Correlation/Tracking Risk” below.
The Underlying Security’s annualized historical volatility rate for the five-year period ended June 30, 2026 was 88.89%. The Underlying Security’s highest volatility rate for any one calendar year during this period was 93.04%. The Underlying Security’s annualized performance during this period was -6.53%. 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] | Leverage Risk. The Fund obtains investment exposure in excess of its net assets by utilizing leverage and may lose more money in market conditions that are adverse to its investment objective than a fund that does not utilize leverage. An investment in the Fund is exposed to the risk that a decline in the daily performance of the Underlying Security will be magnified. This means that an investment in the Fund will be reduced by an amount equal to 2% for every 1% daily decline in the share price of the Underlying Security, not including the costs of financing leverage and other operating expenses, which would further reduce its value. The Fund could theoretically lose an amount greater than its net assets in the event the share price of the Underlying Security declines more than 50%. Leverage will also have the effect of magnifying any differences in the Fund performance’s correlation with the Underlying Security’s share price.

| Risk [Text Block] | Derivatives Risk. Derivatives are financial instruments that derive value from the underlying reference asset or assets, such as stocks, bonds, or funds (including ETFs), interest rates or indexes. The Fund’s investments in derivatives may pose risks in addition to, and greater than, those associated with directly investing in securities or other ordinary investments, including risk related to the market, leverage, imperfect daily correlations with underlying investments or the Fund’s other portfolio holdings, higher price volatility, lack of availability, counterparty risk, liquidity, valuation and legal restrictions. The use of derivatives is a highly specialized activity that involves investment techniques and risks different from those associated with ordinary portfolio securities transactions. The use of derivatives may result in larger losses or smaller gains than directly investing in securities. When the Fund uses derivatives, there may be imperfect correlation between the share price of the Underlying Security and the derivative, which may prevent the Fund from achieving its investment objective. Because derivatives often require only a limited initial investment, the use of derivatives may expose the Fund to losses in excess of those amounts initially invested.
The Fund will be subject to regulatory constraints relating to level of value at risk that the Fund may incur through its derivative portfolio. To the extent the Fund exceeds these regulatory thresholds over an extended period, the Fund may determine that it is necessary to make adjustments to the Fund’s investment strategy, including the desired daily leveraged performance for the Fund. |

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

| Risk [Text Block] | Options Contracts. The use of options contracts involves investment strategies and risks different from those associated with ordinary portfolio securities transactions. The prices of options are volatile and are influenced by, among other things, actual and anticipated changes in the value of the underlying instrument, including the anticipated volatility, which are affected by fiscal and monetary policies and by national and international political, changes in the actual or implied volatility or the reference asset, the time remaining until the expiration of the option contract and economic events. The value of the options contracts in which the Fund invests are substantially influenced by the value of the Underlying Security. The Fund may experience substantial downside from specific option positions and certain option positions held by the Fund may expire worthless. The options held by the Fund are exercisable at the strike price on their expiration date. As an option approaches its expiration date, its value typically increasingly moves with the value of the underlying instrument. However, prior to such date, the value of an option generally does not increase or decrease at the same rate as the underlying instrument. There may at times be an imperfect correlation between the movement in values options contracts and the underlying instrument, and there may at times not be a liquid secondary market for certain options contracts. The value of the options held by the Fund will be determined based on market quotations or other recognized pricing methods. Additionally, as the Fund intends to continuously maintain indirect exposure to the Underlying Security through the use of options contracts, as the options contracts it holds are exercised or expire it will enter into new options contracts, a practice referred to as “rolling.” If the expiring options contracts do not generate proceeds enough to cover the cost of entering into new options contracts, the Fund may experience losses. The use of options to generate leverage introduces additional risks, including significant potential losses if the market moves unfavorably. The leverage inherent in options can amplify both gains and losses, leading to increased volatility and potential for substantial losses, particularly in periods of market uncertainty or low liquidity. Additionally, the Fund may incur losses if the value of the Underlying Security moves against its positions, potentially resulting in a complete loss of the premium paid.

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

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

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

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

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.

Markets for securities or financial instruments could be disrupted by a number of events, including, but not limited to, an economic crisis, natural disasters, epidemics/pandemics, new legislation or regulatory changes inside or outside the United States. Illiquid securities may be difficult to value, especially in changing or volatile markets. If the Fund is forced to sell an illiquid security at an unfavorable time or price, the Fund may be adversely impacted. Certain market conditions or restrictions may prevent the Fund from limiting losses, realizing gains or achieving a high correlation with the Underlying Security. There is no assurance that a security that is deemed liquid when purchased will continue to be liquid. Market illiquidity may cause losses for the Fund.

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

| Risk [Text Block] | Tax Risk. The Fund intends to elect and to qualify each year to be treated as a regulated investment company (a “RIC”) under Subchapter M of the Internal Revenue Code of 1986, as amended (“Code”). As a RIC, the Fund will not be subject to U.S. federal income tax on the portion of its net investment income and net capital gain that it distributes to shareholders, provided that it satisfies certain requirements of the Code. If the Fund does not qualify as a RIC for any taxable year and certain relief provisions are not available, the Fund’s taxable income will be subject to tax at the Fund level and to a further tax at the shareholder level when such income is distributed. To comply with the asset diversification test applicable to a RIC, the Fund will attempt to ensure that the value of swap contracts and options on shares of a single issuer does not exceed 25% of the Fund’s value at the close of any quarter. If the value of swap contracts and options on shares of a single issuer were to exceed 25% of the Fund’s total assets at the end of a tax quarter, the Fund, generally, has a grace period to cure such lack of compliance. If the Fund fails to timely cure, it may no longer be eligible to be treated as a RIC.

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

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

| Prospectus [Line Items] | |||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||
| Risk [Text Block] | Compounding and Market Volatility Risk. The Fund has a daily leveraged investment objective and the Fund’s performance for periods greater than a trading day will be the result of each day’s returns compounded over the period, which is very likely to differ from two times (200%) the Underlying Security’s performance, before the Fund’s management fee and other expenses. Compounding affects all investments but has a more significant impact on funds that aim to replicate leveraged daily returns and that rebalance daily. For the Fund aiming to replicate two times the daily performance of an Underlying Security, if adverse daily performance of the Underlying Security reduces the amount of a shareholder’s investment, any further adverse daily performance will lead to a smaller dollar loss because the shareholder’s investment had already been reduced by the prior adverse performance. Equally, however, if favorable daily performance of the Underlying Security increases the amount of a shareholder’s investment, the dollar amount lost due to future adverse performance will increase because the shareholder’s investment has increased.
The effect of compounding becomes more pronounced as the Underlying Security’s volatility and the holding period increase. The impact of compounding will impact each shareholder differently depending on the period of time an investment in the Fund is held and the volatility of the Underlying Security during a shareholder’s holding period of an investment in the Fund.
The chart below provides examples of how the Underlying Security’s volatility could affect the Fund’s performance. The chart illustrates the impact of two factors that affect the Fund’s performance – the Underlying Security’s volatility and the Underlying Security’s performance. The Underlying Security’s performance shows the percentage change in the share price of the Underlying Security over the specified time period, while the Underlying Security’s volatility is a statistical measure of the magnitude of fluctuations in the returns during that time period. As illustrated below, even if the Underlying Security’s performance over two equal time periods is identical, different Underlying Security volatility (i.e., in magnitude of fluctuations in the share price of the Underlying Security) during the two time periods could result in drastically different Fund performance for the two time periods because of compounding daily returns during the time periods.
Fund performance for periods greater than one single day can be estimated given any set of assumptions for the following factors: a) the Underlying Security volatility; b) the Underlying Security performance; c) period of time; d) financing rates associated with leveraged exposure; and e) other Fund expenses. The chart shows estimated Fund returns for a number of combinations of Underlying Security volatility and Underlying Security performance over a one-year period. Performance shown in the chart assumes that: (i) there were no Fund expenses; (ii) borrowing/lending rates (to obtain leveraged exposure) of 0%. If Fund expenses and/or actual borrowing/lending rates were reflected the estimated returns would be different than those shown. Particularly during periods of higher Underlying Security volatility, compounding will cause results for periods longer than a trading day to vary from two times (200%) the performance of the Underlying Security.
As shown in the chart below, the Fund would be expected to lose 6.1% if there was no change in the share price of the Underlying Security over a one-year period during which the Underlying Security experienced annualized volatility of 25%. If the Underlying Security’s annualized volatility were to rise to 75%, the hypothetical loss for a one-year period would widen to approximately -43%. At higher ranges of volatility, there is a chance of a significant loss of value in the Fund, even if there were no change in the share price of the Underlying Security. For instance, if the Underlying Security’s annualized volatility is 100%, the Fund would be expected to lose 63.2% of its value, even if the cumulative Underlying Security change in the share price of the Underlying Security for the year was 0%.
Areas shaded red (or dark gray) represent those scenarios where the Fund can be expected to return less than two times (200%) the performance of the Underlying Security and those shaded green (or light gray) represent those scenarios where the Fund can be expected to return more than two times (200%) the performance of the Underlying Security. The Fund’s actual performance may be significantly better or worse than the performance shown below as a result of any of the factors discussed above or in the “Daily Correlation/Tracking Risk” below.
The Underlying Security’s annualized historical volatility rate for the five-year period ended June 30, 2026 was 52.02%. The Underlying Security’s highest volatility rate for any one calendar year during this period was 66.0%. The Underlying Security’s annualized performance during this period was 11.67%. Historical Underlying Security volatility and performance are not indications of what Underlying Security volatility and performance will be in the future.

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

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

| Risk [Text Block] | Derivatives Risk. Derivatives are financial instruments that derive value from the underlying reference asset or assets, such as stocks, bonds, or funds (including ETFs), interest rates or indexes. The Fund’s investments in derivatives may pose risks in addition to, and greater than, those associated with directly investing in securities or other ordinary investments, including risk related to the market, leverage, imperfect daily correlations with underlying investments or the Fund’s other portfolio holdings, higher price volatility, lack of availability, counterparty risk, liquidity, valuation and legal restrictions. The use of derivatives is a highly specialized activity that involves investment techniques and risks different from those associated with ordinary portfolio securities transactions. The use of derivatives may result in larger losses or smaller gains than directly investing in securities. When the Fund uses derivatives, there may be imperfect correlation between the share price of the Underlying Security and the derivative, which may prevent the Fund from achieving its investment objective. Because derivatives often require only a limited initial investment, the use of derivatives may expose the Fund to losses in excess of those amounts initially invested.
The Fund will be subject to regulatory constraints relating to level of value at risk that the Fund may incur through its derivative portfolio. To the extent the Fund exceeds these regulatory thresholds over an extended period, the Fund may determine that it is necessary to make adjustments to the Fund’s investment strategy, including the desired daily leveraged performance for the Fund. |

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

| Risk [Text Block] | Options Contracts. The use of options contracts involves investment strategies and risks different from those associated with ordinary portfolio securities transactions. The prices of options are volatile and are influenced by, among other things, actual and anticipated changes in the value of the underlying instrument, including the anticipated volatility, which are affected by fiscal and monetary policies and by national and international political, changes in the actual or implied volatility or the reference asset, the time remaining until the expiration of the option contract and economic events. The value of the options contracts in which the Fund invests are substantially influenced by the value of the Underlying Security. The Fund may experience substantial downside from specific option positions and certain option positions held by the Fund may expire worthless. The options held by the Fund are exercisable at the strike price on their expiration date. As an option approaches its expiration date, its value typically increasingly moves with the value of the underlying instrument. However, prior to such date, the value of an option generally does not increase or decrease at the same rate as the underlying instrument. There may at times be an imperfect correlation between the movement in values options contracts and the underlying instrument, and there may at times not be a liquid secondary market for certain options contracts. The value of the options held by the Fund will be determined based on market quotations or other recognized pricing methods. Additionally, as the Fund intends to continuously maintain indirect exposure to the Underlying Security through the use of options contracts, as the options contracts it holds are exercised or expire it will enter into new options contracts, a practice referred to as “rolling.” If the expiring options contracts do not generate proceeds enough to cover the cost of entering into new options contracts, the Fund may experience losses. The use of options to generate leverage introduces additional risks, including significant potential losses if the market moves unfavorably. The leverage inherent in options can amplify both gains and losses, leading to increased volatility and potential for substantial losses, particularly in periods of market uncertainty or low liquidity. Additionally, the Fund may incur losses if the value of the Underlying Security moves against its positions, potentially resulting in a complete loss of the premium paid.

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

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

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

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

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

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

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

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

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

| Risk [Text Block] | Tax Risk. The Fund intends to elect and to qualify each year to be treated as a regulated investment company (a “RIC”) under Subchapter M of the Internal Revenue Code of 1986, as amended (“Code”). As a RIC, the Fund will not be subject to U.S. federal income tax on the portion of its net investment income and net capital gain that it distributes to shareholders, provided that it satisfies certain requirements of the Code. If the Fund does not qualify as a RIC for any taxable year and certain relief provisions are not available, the Fund’s taxable income will be subject to tax at the Fund level and to a further tax at the shareholder level when such income is distributed. To comply with the asset diversification test applicable to a RIC, the Fund will attempt to ensure that the value of swap contracts and options on shares of a single issuer does not exceed 25% of the Fund’s value at the close of any quarter. If the value of swap contracts and options on shares of a single issuer were to exceed 25% of the Fund’s total assets at the end of a tax quarter, the Fund, generally, has a grace period to cure such lack of compliance. If the Fund fails to timely cure, it may no longer be eligible to be treated as a RIC.

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

| 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 October 21, 2024 to June 30, 2026 (the longest period available) was 102.32%. The Underlying Security’s highest volatility rate for any one calendar year during this period was 123.13%. The Underlying Security’s annualized performance during this period was 31.29%. 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.

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

| Risk [Text Block] | Derivatives Risk. Derivatives are financial instruments that derive value from the underlying reference asset or assets, such as stocks, bonds, or funds (including ETFs), interest rates or indexes. The Fund’s investments in derivatives may pose risks in addition to, and greater than, those associated with directly investing in securities or other ordinary investments, including risk related to the market, leverage, imperfect daily correlations with underlying investments or the Fund’s other portfolio holdings, higher price volatility, lack of availability, counterparty risk, liquidity, valuation and legal restrictions. The use of derivatives is a highly specialized activity that involves investment techniques and risks different from those associated with ordinary portfolio securities transactions. The use of derivatives may result in larger losses or smaller gains than directly investing in securities. When the Fund uses derivatives, there may be imperfect correlation between the share price of the Underlying Security and the derivative, which may prevent the Fund from achieving its investment objective. Because derivatives often require only a limited initial investment, the use of derivatives may expose the Fund to losses in excess of those amounts initially invested.
The Fund will be subject to regulatory constraints relating to level of value at risk that the Fund may incur through its derivative portfolio. To the extent the Fund exceeds these regulatory thresholds over an extended period, the Fund may determine that it is necessary to make adjustments to the Fund’s investment strategy, including the desired daily leveraged performance for the Fund. |

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

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

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

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

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

| Risk [Text Block] | Tax Risk. The Fund intends to elect and to qualify each year to be treated as a regulated investment company (a “RIC”) under Subchapter M of the Internal Revenue Code of 1986, as amended (“Code”). As a RIC, the Fund will not be subject to U.S. federal income tax on the portion of its net investment income and net capital gain that it distributes to shareholders, provided that it satisfies certain requirements of the Code. If the Fund does not qualify as a RIC for any taxable year and certain relief provisions are not available, the Fund’s taxable income will be subject to tax at the Fund level and to a further tax at the shareholder level when such income is distributed. To comply with the asset diversification test applicable to a RIC, the Fund will attempt to ensure that the value of swap contracts and options on shares of a single issuer does not exceed 25% of the Fund’s value at the close of any quarter. If the value of swap contracts and options on shares of a single issuer were to exceed 25% of the Fund’s total assets at the end of a tax quarter, the Fund, generally, has a grace period to cure such lack of compliance. If the Fund fails to timely cure, it may no longer be eligible to be treated as a RIC.

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

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

| Prospectus [Line Items] | |||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||
| Risk [Text Block] | Compounding and Market Volatility Risk. The Fund has a daily leveraged investment objective and the Fund’s performance for periods greater than a trading day will be the result of each day’s returns compounded over the period, which is very likely to differ from two times (200%) the Underlying Security’s performance, before the Fund’s management fee and other expenses. Compounding affects all investments but has a more significant impact on funds that aim to replicate leveraged daily returns and that rebalance daily. For the Fund aiming to replicate two times the daily performance of an Underlying Security, if adverse daily performance of the Underlying Security reduces the amount of a shareholder’s investment, any further adverse daily performance will lead to a smaller dollar loss because the shareholder’s investment had already been reduced by the prior adverse performance. Equally, however, if favorable daily performance of the Underlying Security increases the amount of a shareholder’s investment, the dollar amount lost due to future adverse performance will increase because the shareholder’s investment has increased.
The effect of compounding becomes more pronounced as the Underlying Security’s volatility and the holding period increase. The impact of compounding will impact each shareholder differently depending on the period of time an investment in the Fund is held and the volatility of the Underlying Security during a shareholder’s holding period of an investment in the Fund.
The chart below provides examples of how the Underlying Security’s volatility could affect the Fund’s performance. The chart illustrates the impact of two factors that affect the Fund’s performance – the Underlying Security’s volatility and the Underlying Security’s performance. The Underlying Security’s performance shows the percentage change in the share price of the Underlying Security over the specified time period, while the Underlying Security’s volatility is a statistical measure of the magnitude of fluctuations in the returns during that time period. As illustrated below, even if the Underlying Security’s performance over two equal time periods is identical, different Underlying Security volatility (i.e., in magnitude of fluctuations in the share price of the Underlying Security) during the two time periods could result in drastically different Fund performance for the two time periods because of compounding daily returns during the time periods.
Fund performance for periods greater than one single day can be estimated given any set of assumptions for the following factors: a) the Underlying Security volatility; b) the Underlying Security performance; c) period of time; d) financing rates associated with leveraged exposure; and e) other Fund expenses. The chart shows estimated Fund returns for a number of combinations of Underlying Security volatility and Underlying Security performance over a one-year period. Performance shown in the chart assumes that: (i) there were no Fund expenses; (ii) borrowing/lending rates (to obtain leveraged exposure) of 0%. If Fund expenses and/or actual borrowing/lending rates were reflected the estimated returns would be different than those shown. Particularly during periods of higher Underlying Security volatility, compounding will cause results for periods longer than a trading day to vary from two times (200%) the performance of the Underlying Security.
As shown in the chart below, the Fund would be expected to lose 6.1% if there was no change in the share price of the Underlying Security over a one-year period during which the Underlying Security experienced annualized volatility of 25%. If the Underlying Security’s annualized volatility were to rise to 75%, the hypothetical loss for a one-year period would widen to approximately -43%. At higher ranges of volatility, there is a chance of a significant loss of value in the Fund, even if there were no change in the share price of the Underlying Security. For instance, if the Underlying Security’s annualized volatility is 100%, the Fund would be expected to lose 63.2% of its value, even if the cumulative Underlying Security change in the share price of the Underlying Security for the year was 0%.
Areas shaded red (or dark gray) represent those scenarios where the Fund can be expected to return less than two times (200%) the performance of the Underlying Security and those shaded green (or light gray) represent those scenarios where the Fund can be expected to return more than two times (200%) the performance of the Underlying Security. The Fund’s actual performance may be significantly better or worse than the performance shown below as a result of any of the factors discussed above or in the “Daily Correlation/Tracking Risk” below.
The Underlying Security’s annualized historical volatility rate for the five-year period ended June 30, 2026 was 79.08%. The Underlying Security’s highest volatility rate for any one calendar year during this period was 148.29%. The Underlying Security’s annualized performance during this period was -13.88%. Historical Underlying Security volatility and performance are not indications of what Underlying Security volatility and performance will be in the future.

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

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

| Risk [Text Block] | Derivatives Risk. Derivatives are financial instruments that derive value from the underlying reference asset or assets, such as stocks, bonds, or funds (including ETFs), interest rates or indexes. The Fund’s investments in derivatives may pose risks in addition to, and greater than, those associated with directly investing in securities or other ordinary investments, including risk related to the market, leverage, imperfect daily correlations with underlying investments or the Fund’s other portfolio holdings, higher price volatility, lack of availability, counterparty risk, liquidity, valuation and legal restrictions. The use of derivatives is a highly specialized activity that involves investment techniques and risks different from those associated with ordinary portfolio securities transactions. The use of derivatives may result in larger losses or smaller gains than directly investing in securities. When the Fund uses derivatives, there may be imperfect correlation between the share price of the Underlying Security and the derivative, which may prevent the Fund from achieving its investment objective. Because derivatives often require only a limited initial investment, the use of derivatives may expose the Fund to losses in excess of those amounts initially invested.
The Fund will be subject to regulatory constraints relating to level of value at risk that the Fund may incur through its derivative portfolio. To the extent the Fund exceeds these regulatory thresholds over an extended period, the Fund may determine that it is necessary to make adjustments to the Fund’s investment strategy, including the desired daily leveraged performance for the Fund. |

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

| Risk [Text Block] | Options Contracts. The use of options contracts involves investment strategies and risks different from those associated with ordinary portfolio securities transactions. The prices of options are volatile and are influenced by, among other things, actual and anticipated changes in the value of the underlying instrument, including the anticipated volatility, which are affected by fiscal and monetary policies and by national and international political, changes in the actual or implied volatility or the reference asset, the time remaining until the expiration of the option contract and economic events. The value of the options contracts in which the Fund invests are substantially influenced by the value of the Underlying Security. The Fund may experience substantial downside from specific option positions and certain option positions held by the Fund may expire worthless. The options held by the Fund are exercisable at the strike price on their expiration date. As an option approaches its expiration date, its value typically increasingly moves with the value of the underlying instrument. However, prior to such date, the value of an option generally does not increase or decrease at the same rate as the underlying instrument. There may at times be an imperfect correlation between the movement in values options contracts and the underlying instrument, and there may at times not be a liquid secondary market for certain options contracts. The value of the options held by the Fund will be determined based on market quotations or other recognized pricing methods. Additionally, as the Fund intends to continuously maintain indirect exposure to the Underlying Security through the use of options contracts, as the options contracts it holds are exercised or expire it will enter into new options contracts, a practice referred to as “rolling.” If the expiring options contracts do not generate proceeds enough to cover the cost of entering into new options contracts, the Fund may experience losses. The use of options to generate leverage introduces additional risks, including significant potential losses if the market moves unfavorably. The leverage inherent in options can amplify both gains and losses, leading to increased volatility and potential for substantial losses, particularly in periods of market uncertainty or low liquidity. Additionally, the Fund may incur losses if the value of the Underlying Security moves against its positions, potentially resulting in a complete loss of the premium paid.

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

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

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

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

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

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

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.

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

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

| Risk [Text Block] | Tax Risk. The Fund intends to elect and to qualify each year to be treated as a regulated investment company (a “RIC”) under Subchapter M of the Internal Revenue Code of 1986, as amended (“Code”). As a RIC, the Fund will not be subject to U.S. federal income tax on the portion of its net investment income and net capital gain that it distributes to shareholders, provided that it satisfies certain requirements of the Code. If the Fund does not qualify as a RIC for any taxable year and certain relief provisions are not available, the Fund’s taxable income will be subject to tax at the Fund level and to a further tax at the shareholder level when such income is distributed. To comply with the asset diversification test applicable to a RIC, the Fund will attempt to ensure that the value of swap contracts and options on shares of a single issuer does not exceed 25% of the Fund’s value at the close of any quarter. If the value of swap contracts and options on shares of a single issuer were to exceed 25% of the Fund’s total assets at the end of a tax quarter, the Fund, generally, has a grace period to cure such lack of compliance. If the Fund fails to timely cure, it may no longer be eligible to be treated as a RIC.

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

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 five-year period ended June 30, 2026 was 82.92%. The Underlying Security’s highest volatility rate for any one calendar year during this period was 91.08%. The Underlying Security’s annualized performance during this period was -7.99%. Historical Underlying Security volatility and performance are not indications of what Underlying Security volatility and performance will be in the future.

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

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

| Risk [Text Block] | Derivatives Risk. Derivatives are financial instruments that derive value from the underlying reference asset or assets, such as stocks, bonds, or funds (including ETFs), interest rates or indexes. The Fund’s investments in derivatives may pose risks in addition to, and greater than, those associated with directly investing in securities or other ordinary investments, including risk related to the market, leverage, imperfect daily correlations with underlying investments or the Fund’s other portfolio holdings, higher price volatility, lack of availability, counterparty risk, liquidity, valuation and legal restrictions. The use of derivatives is a highly specialized activity that involves investment techniques and risks different from those associated with ordinary portfolio securities transactions. The use of derivatives may result in larger losses or smaller gains than directly investing in securities. When the Fund uses derivatives, there may be imperfect correlation between the share price of the Underlying Security and the derivative, which may prevent the Fund from achieving its investment objective. Because derivatives often require only a limited initial investment, the use of derivatives may expose the Fund to losses in excess of those amounts initially invested.
The Fund will be subject to regulatory constraints relating to level of value at risk that the Fund may incur through its derivative portfolio. To the extent the Fund exceeds these regulatory thresholds over an extended period, the Fund may determine that it is necessary to make adjustments to the Fund’s investment strategy, including the desired daily leveraged performance for the Fund. |

| 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.

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

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

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

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

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.

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

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

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

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

| Risk [Text Block] | Tax Risk. The Fund intends to elect and to qualify each year to be treated as a regulated investment company (a “RIC”) under Subchapter M of the Internal Revenue Code of 1986, as amended (“Code”). As a RIC, the Fund will not be subject to U.S. federal income tax on the portion of its net investment income and net capital gain that it distributes to shareholders, provided that it satisfies certain requirements of the Code. If the Fund does not qualify as a RIC for any taxable year and certain relief provisions are not available, the Fund’s taxable income will be subject to tax at the Fund level and to a further tax at the shareholder level when such income is distributed. To comply with the asset diversification test applicable to a RIC, the Fund will attempt to ensure that the value of swap contracts and options on shares of a single issuer does not exceed 25% of the Fund’s value at the close of any quarter. If the value of swap contracts and options on shares of a single issuer were to exceed 25% of the Fund’s total assets at the end of a tax quarter, the Fund, generally, has a grace period to cure such lack of compliance. If the Fund fails to timely cure, it may no longer be eligible to be treated as a RIC.

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

| 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 27, 2024 to June 30, 2026 (the longest period available) was 111.12%. The Underlying Security’s highest volatility rate for any one calendar year during this period was 161.0%. The Underlying Security’s annualized performance during this period was -32.52%. Historical Underlying Security and performance are not indications of what Underlying Security volatility and performance will be in the future.

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

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

| Risk [Text Block] | Derivatives Risk. Derivatives are financial instruments that derive value from the underlying reference asset or assets, such as stocks, bonds, or funds (including ETFs), interest rates or indexes. The Fund’s investments in derivatives may pose risks in addition to, and greater than, those associated with directly investing in securities or other ordinary investments, including risk related to the market, leverage, imperfect daily correlations with underlying investments or the Fund’s other portfolio holdings, higher price volatility, lack of availability, counterparty risk, liquidity, valuation and legal restrictions. The use of derivatives is a highly specialized activity that involves investment techniques and risks different from those associated with ordinary portfolio securities transactions. The use of derivatives may result in larger losses or smaller gains than directly investing in securities. When the Fund uses derivatives, there may be imperfect correlation between the share price of the Underlying Security and the derivative, which may prevent the Fund from achieving its investment objective. Because derivatives often require only a limited initial investment, the use of derivatives may expose the Fund to losses in excess of those amounts initially invested.
The Fund will be subject to regulatory constraints relating to level of value at risk that the Fund may incur through its derivative portfolio. To the extent the Fund exceeds these regulatory thresholds over an extended period, the Fund may determine that it is necessary to make adjustments to the Fund’s investment strategy, including the desired daily leveraged performance for the Fund. |

| 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] | 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.

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.

| Risk [Text Block] | Tax Risk. The Fund intends to elect and to qualify each year to be treated as a regulated investment company (a “RIC”) under Subchapter M of the Internal Revenue Code of 1986, as amended (“Code”). As a RIC, the Fund will not be subject to U.S. federal income tax on the portion of its net investment income and net capital gain that it distributes to shareholders, provided that it satisfies certain requirements of the Code. If the Fund does not qualify as a RIC for any taxable year and certain relief provisions are not available, the Fund’s taxable income will be subject to tax at the Fund level and to a further tax at the shareholder level when such income is distributed. To comply with the asset diversification test applicable to a RIC, the Fund will attempt to ensure that the value of swap contracts and options on shares of a single issuer does not exceed 25% of the Fund’s value at the close of any quarter. If the value of swap contracts and options on shares of a single issuer were to exceed 25% of the Fund’s total assets at the end of a tax quarter, the Fund, generally, has a grace period to cure such lack of compliance. If the Fund fails to timely cure, it may no longer be eligible to be treated as a RIC.

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

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

| Prospectus [Line Items] | |||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||
| Risk [Text Block] | Compounding and Market Volatility Risk. The Fund has a daily leveraged investment objective and the Fund’s performance for periods greater than a trading day will be the result of each day’s returns compounded over the period, which is very likely to differ from two times (200%) the Underlying Security’s performance, before the Fund’s management fee and other expenses. Compounding affects all investments but has a more significant impact on funds that aim to replicate leveraged daily returns and that rebalance daily. For the Fund aiming to replicate two times the daily performance of an Underlying Security, if adverse daily performance of the Underlying Security reduces the amount of a shareholder’s investment, any further adverse daily performance will lead to a smaller dollar loss because the shareholder’s investment had already been reduced by the prior adverse performance. Equally, however, if favorable daily performance of the Underlying Security increases the amount of a shareholder’s investment, the dollar amount lost due to future adverse performance will increase because the shareholder’s investment has increased.
The effect of compounding becomes more pronounced as the Underlying Security’s volatility and the holding period increase. The impact of compounding will impact each shareholder differently depending on the period of time an investment in the Fund is held and the volatility of the Underlying Security during a shareholder’s holding period of an investment in the Fund.
The chart below provides examples of how the Underlying Security’s volatility could affect the Fund’s performance. The chart illustrates the impact of two factors that affect the Fund’s performance – the Underlying Security’s volatility and the Underlying Security’s performance. The Underlying Security’s performance shows the percentage change in the share price of the Underlying Security over the specified time period, while the Underlying Security’s volatility is a statistical measure of the magnitude of fluctuations in the returns during that time period. As illustrated below, even if the Underlying Security’s performance over two equal time periods is identical, different Underlying Security volatility (i.e., in magnitude of fluctuations in the share price of the Underlying Security) during the two time periods could result in drastically different Fund performance for the two time periods because of compounding daily returns during the time periods.
Fund performance for periods greater than one single day can be estimated given any set of assumptions for the following factors: a) the Underlying Security volatility; b) the Underlying Security performance; c) period of time; d) financing rates associated with leveraged exposure; and e) other Fund expenses. The chart shows estimated Fund returns for a number of combinations of Underlying Security volatility and Underlying Security performance over a one-year period. Performance shown in the chart assumes that: (i) there were no Fund expenses; (ii) borrowing/lending rates (to obtain leveraged exposure) of 0%. If Fund expenses and/or actual borrowing/lending rates were reflected the estimated returns would be different than those shown. Particularly during periods of higher Underlying Security volatility, compounding will cause results for periods longer than a trading day to vary from two times (200%) the performance of the Underlying Security.
As shown in the chart below, the Fund would be expected to lose 6.1% if there was no change in the share price of the Underlying Security over a one-year period during which the Underlying Security experienced annualized volatility of 25%. If the Underlying Security’s annualized volatility were to rise to 75%, the hypothetical loss for a one-year period would widen to approximately -43%. At higher ranges of volatility, there is a chance of a significant loss of value in the Fund, even if there were no change in the share price of the Underlying Security. For instance, if the Underlying Security’s annualized volatility is 100%, the Fund would be expected to lose 63.2% of its value, even if the cumulative Underlying Security change in the share price of the Underlying Security for the year was 0%.
Areas shaded red (or dark gray) represent those scenarios where the Fund can be expected to return less than two times (200%) the performance of the Underlying Security and those shaded green (or light gray) represent those scenarios where the Fund can be expected to return more than two times (200%) the performance of the Underlying Security. The Fund’s actual performance may be significantly better or worse than the performance shown below as a result of any of the factors discussed above or in the “Daily Correlation/Tracking Risk” below.
The Underlying Security’s annualized historical volatility rate for the five-year period ended June 30, 2026 was 110.71%. The Underlying Security’s highest volatility rate for any one calendar year during this period was 131.50%. The Underlying Security’s annualized performance during this period was 32.56%. Historical Underlying Security volatility and performance are not indications of what Underlying Security volatility and performance will be in the future.

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

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

| Risk [Text Block] | Derivatives Risk. Derivatives are financial instruments that derive value from the underlying reference asset or assets, such as stocks, bonds, or funds (including ETFs), interest rates or indexes. The Fund’s investments in derivatives may pose risks in addition to, and greater than, those associated with directly investing in securities or other ordinary investments, including risk related to the market, leverage, imperfect daily correlations with underlying investments or the Fund’s other portfolio holdings, higher price volatility, lack of availability, counterparty risk, liquidity, valuation and legal restrictions. The use of derivatives is a highly specialized activity that involves investment techniques and risks different from those associated with ordinary portfolio securities transactions. The use of derivatives may result in larger losses or smaller gains than directly investing in securities. When the Fund uses derivatives, there may be imperfect correlation between the share price of the Underlying Security and the derivative, which may prevent the Fund from achieving its investment objective. Because derivatives often require only a limited initial investment, the use of derivatives may expose the Fund to losses in excess of those amounts initially invested.
The Fund will be subject to regulatory constraints relating to level of value at risk that the Fund may incur through its derivative portfolio. To the extent the Fund exceeds these regulatory thresholds over an extended period, the Fund may determine that it is necessary to make adjustments to the Fund’s investment strategy, including the desired daily leveraged performance for the Fund. |

| 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.

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

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

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

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

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

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

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 Fund’s own shares.”

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

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

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

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

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

| Risk [Text Block] | Tax Risk. The Fund intends to elect and to qualify each year to be treated as a regulated investment company (a “RIC”) under Subchapter M of the Internal Revenue Code of 1986, as amended (“Code”). As a RIC, the Fund will not be subject to U.S. federal income tax on the portion of its net investment income and net capital gain that it distributes to shareholders, provided that it satisfies certain requirements of the Code. If the Fund does not qualify as a RIC for any taxable year and certain relief provisions are not available, the Fund’s taxable income will be subject to tax at the Fund level and to a further tax at the shareholder level when such income is distributed. To comply with the asset diversification test applicable to a RIC, the Fund will attempt to ensure that the value of swap contracts and options on shares of a single issuer does not exceed 25% of the Fund’s value at the close of any quarter. If the value of swap contracts and options on shares of a single issuer were to exceed 25% of the Fund’s total assets at the end of a tax quarter, the Fund, generally, has a grace period to cure such lack of compliance. If the Fund fails to timely cure, it may no longer be eligible to be treated as a RIC.

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

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 April 25, 2024 to June 30, 2026 (the longest period available) was 62.13%. The Underlying Security’s highest volatility rate for any one calendar year during this period was 74.62%. The Underlying Security’s annualized performance during this period was 42.59%. Historical Underlying Security volatility and performance are not indications of what Underlying Security volatility and performance will be in the future.

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

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

| Risk [Text Block] | Derivatives Risk. Derivatives are financial instruments that derive value from the underlying reference asset or assets, such as stocks, bonds, or funds (including ETFs), interest rates or indexes. The Fund’s investments in derivatives may pose risks in addition to, and greater than, those associated with directly investing in securities or other ordinary investments, including risk related to the market, leverage, imperfect daily correlations with underlying investments or the Fund’s other portfolio holdings, higher price volatility, lack of availability, counterparty risk, liquidity, valuation and legal restrictions. The use of derivatives is a highly specialized activity that involves investment techniques and risks different from those associated with ordinary portfolio securities transactions. The use of derivatives may result in larger losses or smaller gains than directly investing in securities. When the Fund uses derivatives, there may be imperfect correlation between the share price of the Underlying Security and the derivative, which may prevent the Fund from achieving its investment objective. Because derivatives often require only a limited initial investment, the use of derivatives may expose the Fund to losses in excess of those amounts initially invested.
The Fund will be subject to regulatory constraints relating to level of value at risk that the Fund may incur through its derivative portfolio. To the extent the Fund exceeds these regulatory thresholds over an extended period, the Fund may determine that it is necessary to make adjustments to the Fund’s investment strategy, including the desired daily leveraged performance for the Fund. |

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

| Risk [Text Block] | Options Contracts. The use of options contracts involves investment strategies and risks different from those associated with ordinary portfolio securities transactions. The prices of options are volatile and are influenced by, among other things, actual and anticipated changes in the value of the underlying instrument, including the anticipated volatility, which are affected by fiscal and monetary policies and by national and international political, changes in the actual or implied volatility or the reference asset, the time remaining until the expiration of the option contract and economic events. The value of the options contracts in which the Fund invests are substantially influenced by the value of the Underlying Security. The Fund may experience substantial downside from specific option positions and certain option positions held by the Fund may expire worthless. The options held by the Fund are exercisable at the strike price on their expiration date. As an option approaches its expiration date, its value typically increasingly moves with the value of the underlying instrument. However, prior to such date, the value of an option generally does not increase or decrease at the same rate as the underlying instrument. There may at times be an imperfect correlation between the movement in values options contracts and the underlying instrument, and there may at times not be a liquid secondary market for certain options contracts. The value of the options held by the Fund will be determined based on market quotations or other recognized pricing methods. Additionally, as the Fund intends to continuously maintain indirect exposure to the Underlying Security through the use of options contracts, as the options contracts it holds are exercised or expire it will enter into new options contracts, a practice referred to as “rolling.” If the expiring options contracts do not generate proceeds enough to cover the cost of entering into new options contracts, the Fund may experience losses. The use of options to generate leverage introduces additional risks, including significant potential losses if the market moves unfavorably. The leverage inherent in options can amplify both gains and losses, leading to increased volatility and potential for substantial losses, particularly in periods of market uncertainty or low liquidity. Additionally, the Fund may incur losses if the value of the Underlying Security moves against its positions, potentially resulting in a complete loss of the premium paid.

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

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

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

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

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

| 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.

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.

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

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

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

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

| Risk [Text Block] | Tax Risk. The Fund intends to elect and to qualify each year to be treated as a regulated investment company (a “RIC”) under Subchapter M of the Internal Revenue Code of 1986, as amended (“Code”). As a RIC, the Fund will not be subject to U.S. federal income tax on the portion of its net investment income and net capital gain that it distributes to shareholders, provided that it satisfies certain requirements of the Code. If the Fund does not qualify as a RIC for any taxable year and certain relief provisions are not available, the Fund’s taxable income will be subject to tax at the Fund level and to a further tax at the shareholder level when such income is distributed. To comply with the asset diversification test applicable to a RIC, the Fund will attempt to ensure that the value of swap contracts and options on shares of a single issuer does not exceed 25% of the Fund’s value at the close of any quarter. If the value of swap contracts and options on shares of a single issuer were to exceed 25% of the Fund’s total assets at the end of a tax quarter, the Fund, generally, has a grace period to cure such lack of compliance. If the Fund fails to timely cure, it may no longer be eligible to be treated as a RIC.

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

| 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 47.57%. The Underlying Security’s highest volatility rate for any one calendar year during this period was 55.77% and volatility for a shorter period of time may have been substantially higher. The Underlying Security’s annualized performance during this period was 49.60%. Historical Underlying Security volatility and performance are not indications of what Underlying Security volatility and performance will be in the future.

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

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

| Risk [Text Block] | Derivatives Risk. Derivatives are financial instruments that derive value from the underlying reference asset or assets, such as stocks, bonds, or funds (including ETFs), interest rates or indexes. The Fund’s investments in derivatives may pose risks in addition to, and greater than, those associated with directly investing in securities or other ordinary investments, including risk related to the market, leverage, imperfect daily correlations with underlying investments or the Fund’s other portfolio holdings, higher price volatility, lack of availability, counterparty risk, liquidity, valuation and legal restrictions. The use of derivatives is a highly specialized activity that involves investment techniques and risks different from those associated with ordinary portfolio securities transactions. The use of derivatives may result in larger losses or smaller gains than directly investing in securities. When the Fund uses derivatives, there may be imperfect correlation between the share price of the Underlying Security and the derivative, which may prevent the Fund from achieving its investment objective. Because derivatives often require only a limited initial investment, the use of derivatives may expose the Fund to losses in excess of those amounts initially invested.
The Fund will be subject to regulatory constraints relating to level of value at risk that the Fund may incur through its derivative portfolio. To the extent the Fund exceeds these regulatory thresholds over an extended period, the Fund may determine that it is necessary to make adjustments to the Fund’s investment strategy, including the desired daily leveraged performance for the Fund. |

| 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.

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.

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 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.

Short sellers may also play a significant role in trading ANET, 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 ANET’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 ANET, trading in shares of related funds may be impacted, either temporarily or indefinitely.

| Risk [Text Block] | ANET Performance Risk. ANET may fail to meet its publicly announced guidelines or other expectations about its business, which could cause the price of ANET to decline. ANET provides guidance regarding its expected financial and business performance, such as projections regarding sales and production, as well as anticipated future revenues, gross margins, profitability and cash flows. Correctly identifying key factors affecting business conditions and predicting future events is inherently an uncertain process, and the guidance ANET provides may not ultimately be accurate. If ANET’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 ANET could decline significantly.

| Risk [Text Block] | Communications Equipment Industry Risks. The communications equipment industry can be significantly affected by failure to obtain, or delays in obtaining, financing or regulatory approval, intense competition, product compatibility, consumer preferences, corporate capital expenditures, and rapid obsolescence. Communications services companies are subject to extensive government regulation. The costs of complying with governmental regulations, delays or failure to receive required regulatory approvals, or the enactment of new adverse regulatory requirements may adversely affect the business of such companies. These companies can also be significantly affected by intense competition, including competition with alternative technologies such as wireless communications (including with 5G and other technologies), product compatibility, consumer preferences, rapid product obsolescence, and research and development of new products. Technological innovations may make the products and services of such companies obsolete.

| Risk [Text Block] | Information Technology and Networking Infrastructure Risk. ANET’s business depends on the overall demand for information technology, network connectivity and access to data and applications. The markets in which ANET competes, including the markets for data center, campus networking, network visibility and security and AI, are intensely competitive. Weak domestic or global economic conditions and continuing economic uncertainty, fear or anticipation of such conditions, a recession, geopolitical pressures, including international trade disputes, changes in tariff policies, global pandemics, or a reduction in information technology and network infrastructure spending could adversely affect ANET’s business, financial condition or results of operations.
In addition, the networking market is rapidly evolving. A substantial portion of ANET’s business and revenue depends on the growth and evolution of the networking market, including the market for AI networks and the future deployment of Ethernet networking solutions in these AI networks. In particular, recent technologies, such as generative and agentic AI models, have emerged, and while they have driven increased demand for networking, the market is rapidly changing and the long-term trajectory is unknown. If this market does not evolve as ANET anticipates and its target customers do not adopt its networking solutions, ANET may not be able to compete effectively, and its ability to generate revenue will suffer.

| Risk [Text Block] | Intellectual Property Risks: ANET’s success and ability to compete depends substantially upon its core technology and intellectual property. ANET relies on patent, trademark and copyright laws, trade secret protection and confidentiality agreements with its employees, customers, resellers, systems integrators, manufacturers, and others to protect its intellectual property rights. ANET’s industry is characterized by the existence of a large number of patents and frequent claims and related litigation regarding patent and other intellectual property rights. If ANET becomes more successful, it believes that competitors will be more likely to try to develop similar products that may infringe its proprietary rights. Further, from time to time, third parties may assert patent, copyright, trademark and other intellectual property rights against ANET. Successful claims of infringement by a third-party, if any, could prevent ANET from distributing certain products or performing certain services, require ANET to expend time and money to develop non-infringing solutions or force ANET to pay substantial damages, royalties or other fees.

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

| Prospectus [Line Items] | |||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||
| Risk [Text Block] | Compounding and Market Volatility Risk. The Fund has a daily leveraged investment objective and the Fund’s performance for periods greater than a trading day will be the result of each day’s returns compounded over the period, which is very likely to differ from two times (200%) the Underlying Security’s performance, before the Fund’s management fee and other expenses. Compounding affects all investments but has a more significant impact on funds that aim to replicate leveraged daily returns and that rebalance daily. For the Fund aiming to replicate two times the daily performance of an Underlying Security, if adverse daily performance of the Underlying Security reduces the amount of a shareholder’s investment, any further adverse daily performance will lead to a smaller dollar loss because the shareholder’s investment had already been reduced by the prior adverse performance. Equally, however, if favorable daily performance of the Underlying Security increases the amount of a shareholder’s investment, the dollar amount lost due to future adverse performance will increase because the shareholder’s investment has increased.
The effect of compounding becomes more pronounced as the Underlying Security’s volatility and the holding period increase. The impact of compounding will impact each shareholder differently depending on the period of time an investment in the Fund is held and the volatility of the Underlying Security during a shareholder’s holding period of an investment in the Fund.
The chart below provides examples of how the Underlying Security’s volatility could affect the Fund’s performance. The chart illustrates the impact of two factors that affect the Fund’s performance – the Underlying Security’s volatility and the Underlying Security’s performance. The Underlying Security’s performance shows the percentage change in the share price of the Underlying Security over the specified time period, while the Underlying Security’s volatility is a statistical measure of the magnitude of fluctuations in the returns during that time period. As illustrated below, even if the Underlying Security’s performance over two equal time periods is identical, different Underlying Security volatility (i.e., in magnitude of fluctuations in the share price of the Underlying Security) during the two time periods could result in drastically different Fund performance for the two time periods because of compounding daily returns during the time periods.
Fund performance for periods greater than one single day can be estimated given any set of assumptions for the following factors: a) the Underlying Security volatility; b) the Underlying Security performance; c) period of time; d) financing rates associated with leveraged exposure; and e) other Fund expenses. The chart shows estimated Fund returns for a number of combinations of Underlying Security volatility and Underlying Security performance over a one-year period. Performance shown in the chart assumes that: (i) there were no Fund expenses; (ii) borrowing/lending rates (to obtain leveraged exposure) of 0%. If Fund expenses and/or actual borrowing/lending rates were reflected the estimated returns would be different than those shown. Particularly during periods of higher Underlying Security volatility, compounding will cause results for periods longer than a trading day to vary from two times (200%) the performance of the Underlying Security.
As shown in the chart below, the Fund would be expected to lose 6.1% if there was no change in the share price of the Underlying Security over a one-year period during which the Underlying Security experienced annualized volatility of 25%. If the Underlying Security’s annualized volatility were to rise to 75%, the hypothetical loss for a one-year period would widen to approximately -43%. At higher ranges of volatility, there is a chance of a significant loss of value in the Fund, even if there were no change in the share price of the Underlying Security. For instance, if the Underlying Security’s annualized volatility is 100%, the Fund would be expected to lose 63.2% of its value, even if the cumulative Underlying Security change in the share price of the Underlying Security for the year was 0%.
Areas shaded red (or dark gray) represent those scenarios where the Fund can be expected to return less than two times (200%) the performance of the Underlying Security and those shaded green (or light gray) represent those scenarios where the Fund can be expected to return more than two times (200%) the performance of the Underlying Security. The Fund’s actual performance may be significantly better or worse than the performance shown below as a result of any of the factors discussed above or in the “Daily Correlation/Tracking Risk” below.
The Underlying Security’s annualized historical volatility rate for the period from September 14, 2023 to June 30, 2026 (the longest period available) was 75.02%. The Underlying Security’s highest volatility rate for any one calendar year during this period was 87.29% and volatility for a shorter period of time may have been substantially higher. The Underlying Security’s annualized performance during this period was 47.34%. Historical Underlying Security volatility and performance are not indications of what Underlying Security volatility and performance will be in the future.

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

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

| Risk [Text Block] | Derivatives Risk. Derivatives are financial instruments that derive value from the underlying reference asset or assets, such as stocks, bonds, or funds (including ETFs), interest rates or indexes. The Fund’s investments in derivatives may pose risks in addition to, and greater than, those associated with directly investing in securities or other ordinary investments, including risk related to the market, leverage, imperfect daily correlations with underlying investments or the Fund’s other portfolio holdings, higher price volatility, lack of availability, counterparty risk, liquidity, valuation and legal restrictions. The use of derivatives is a highly specialized activity that involves investment techniques and risks different from those associated with ordinary portfolio securities transactions. The use of derivatives may result in larger losses or smaller gains than directly investing in securities. When the Fund uses derivatives, there may be imperfect correlation between the share price of the Underlying Security and the derivative, which may prevent the Fund from achieving its investment objective. Because derivatives often require only a limited initial investment, the use of derivatives may expose the Fund to losses in excess of those amounts initially invested.
The Fund will be subject to regulatory constraints relating to level of value at risk that the Fund may incur through its derivative portfolio. To the extent the Fund exceeds these regulatory thresholds over an extended period, the Fund may determine that it is necessary to make adjustments to the Fund’s investment strategy, including the desired daily leveraged performance for the Fund. |

| 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 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 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] | Semiconductor 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.

| 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 44.76%. The Underlying Security’s highest volatility rate for any one calendar year during this period was 56.27% and volatility for a shorter period of time may have been substantially higher. The Underlying Security’s annualized performance during this period was 7.56%. Historical Underlying Security volatility and performance are not indications of what Underlying Security volatility and performance will be in the future.

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

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

| Risk [Text Block] | Derivatives Risk. Derivatives are financial instruments that derive value from the underlying reference asset or assets, such as stocks, bonds, or funds (including ETFs), interest rates or indexes. The Fund’s investments in derivatives may pose risks in addition to, and greater than, those associated with directly investing in securities or other ordinary investments, including risk related to the market, leverage, imperfect daily correlations with underlying investments or the Fund’s other portfolio holdings, higher price volatility, lack of availability, counterparty risk, liquidity, valuation and legal restrictions. The use of derivatives is a highly specialized activity that involves investment techniques and risks different from those associated with ordinary portfolio securities transactions. The use of derivatives may result in larger losses or smaller gains than directly investing in securities. When the Fund uses derivatives, there may be imperfect correlation between the share price of the Underlying Security and the derivative, which may prevent the Fund from achieving its investment objective. Because derivatives often require only a limited initial investment, the use of derivatives may expose the Fund to losses in excess of those amounts initially invested.
The Fund will be subject to regulatory constraints relating to level of value at risk that the Fund may incur through its derivative portfolio. To the extent the Fund exceeds these regulatory thresholds over an extended period, the Fund may determine that it is necessary to make adjustments to the Fund’s investment strategy, including the desired daily leveraged performance for the Fund. |

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

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

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

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

Although the Underlying Security’s shares are listed for trading on an exchange, there can be no assurance that an active trading market for such shares will be available at all times and the Exchange may halt trading of such shares in certain circumstances. A halt in trading in the Underlying Security’s shares is expected, in turn, to result in a halt in the trading in the Fund’s Shares. Trading in the Underlying Security’s and/or Fund’s Shares on the Exchange may be halted due to market conditions or for reasons that, in the view of the Exchange, make trading in the Underlying Security’s and/or Fund’s Shares inadvisable.

| Risk [Text Block] | Tax Risk. The Fund intends to elect and 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] | UBER Trading Risk. The trading price of UBER may be subject to volatility and could experience wide fluctuations due to various factors. Short sellers may also play a significant role in trading UBER, 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 UBER’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 UBER, trading in shares of related funds may be impacted, either temporarily or indefinitely.

| Risk [Text Block] | UBER Performance Risk. UBER may fail to meet its publicly announced guidelines or other expectations about its business, which could cause the price of UBER to decline. UBER provides guidance regarding its expected financial and business performance, such as anticipated future revenues, gross margins, profitability and cash flows. Correctly identifying key factors affecting business conditions and predicting future events is inherently an uncertain process, and the guidance UBER provides may not ultimately be accurate. If UBER’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 UBER could decline significantly.

| Risk [Text Block] | Driver Classification Risk. The classification of Uber’s drivers (“Drivers”) is currently being challenged in courts, by legislators and by government agencies in the United States and abroad. Uber is involved in numerous legal proceedings globally, including putative class and collective class action lawsuits, demands for arbitration, charges and claims before administrative agencies, and investigations or audits by labor, social security, and tax authorities that claim that Drivers should be treated as Uber’s employees (or as workers or quasi-employees where those statuses exist), rather than as independent contractors. Uber believes that Drivers are independent contractors because, among other things, they can choose whether, when, and where to provide services on Uber’s platform, are free to provide services on competitors’ platforms, and provide a vehicle to perform services on Uber’s platform. Nevertheless, Uber may not be successful in defending the classification of Drivers in some or all jurisdictions. Furthermore, the costs associated with defending, settling, or resolving pending and future lawsuits (including demands for arbitration) relating to the classification of Drivers have been and may continue to be material to Uber’s business.

| 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 five-year period ended June 30, 2026 was 32.33%. The Underlying Security’s highest volatility rate for any one calendar year 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 leveraged correlation to the Underlying Security and therefore achieve its daily leveraged investment objective. To achieve a high degree of leveraged correlation with the Underlying Security, the Fund seeks to rebalance its portfolio daily to keep exposure consistent with its daily leveraged investment objective. The possibility of the Fund being materially over- or under-exposed to the Underlying Security increases on days when the Underlying Security is volatile near the close of the trading day. Market disruptions, regulatory restrictions and extreme volatility will also adversely affect the Fund’s ability to adjust exposure to the required levels. If there is a significant intra-day market event and/or the Underlying Security experiences a significant increase or decline, the Fund may not meet its investment objective, be able to rebalance its portfolio appropriately, or may experience significant premiums or discounts, or widened bid-ask spreads.
The Fund may have difficulty achieving its daily leveraged investment objective due to fees, expenses, transaction costs, financing costs related to the use of derivatives, investments in ETFs, directly or indirectly, income items, valuation methodology, accounting standards and disruptions or illiquidity in the markets for the securities or derivatives held by the Fund. The Fund may be subject to large movements of assets into and out of the Fund, potentially resulting in the Fund being over- or under-exposed to the Underlying Security. The Fund may take or refrain from taking positions to improve the tax efficiency or to comply with various regulatory restrictions, either of which may negatively impact the Fund’s leveraged correlation to the Underlying Security.

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

| Risk [Text Block] | Derivatives Risk. Derivatives are financial instruments that derive value from the underlying reference asset or assets, such as stocks, bonds, or funds (including ETFs), interest rates or indexes. The Fund’s investments in derivatives may pose risks in addition to, and greater than, those associated with directly investing in securities or other ordinary investments, including risk related to the market, leverage, imperfect daily correlations with underlying investments or the Fund’s other portfolio holdings, higher price volatility, lack of availability, counterparty risk, liquidity, valuation and legal restrictions. The use of derivatives is a highly specialized activity that involves investment techniques and risks different from those associated with ordinary portfolio securities transactions. The use of derivatives may result in larger losses or smaller gains than directly investing in securities. When the Fund uses derivatives, there may be imperfect correlation between the share price of the Underlying Security and the derivative, which may prevent the Fund from achieving its investment objective. Because derivatives often require only a limited initial investment, the use of derivatives may expose the Fund to losses in excess of those amounts initially invested.
The Fund will be subject to regulatory constraints relating to level of value at risk that the Fund may incur through its derivative portfolio. To the extent the Fund exceeds these regulatory thresholds over an extended period, the Fund may determine that it is necessary to make adjustments to the Fund’s investment strategy, including the desired daily leveraged performance for the Fund. |

| 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.

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 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.

| 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 Internal Revenue Code of 1986, as amended (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.

LLY depends on products with intellectual property protection for most of LLY’s revenues, cash flows, and earnings; the loss of effective intellectual property protection for certain of LLY’s products has resulted, and in the future is likely to continue to result, in rapid and severe declines in revenues for those products. LLY’s long-term success depends on intellectual property protection; if LLY’s intellectual property rights are invalidated, circumvented, or weakened, LLY’s business will be adversely affected.

| Risk [Text Block] | LLY Trading Risk. The trading price of LLY may be subject to volatility and could experience wide fluctuations due to various factors. The pharmaceutical industry, including LLY, operates within a market that has historically witnessed significant price and volume fluctuations, sometimes unrelated to the companies’ operating performance. Short sellers may also play a significant role in trading LLY, 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 LLY’s stock price disproportionately, as LLY often receives heightened public attention regardless of its operational performance. Additionally, following periods of market volatility, companies, including LLY, have faced securities class action litigation. LLY has been subject to such litigation in the past and continues to defend against such actions. However, 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 LLY, trading in shares of related funds may be impacted, either temporarily or indefinitely.

| Risk [Text Block] | LLY Performance Risk. LLY may fail to meet its publicly announced guidelines or other expectations about its business, which could cause the price of LLY to decline. LLY provides guidance regarding its expected financial and business performance, such as projections regarding sales and production, as well as anticipated future revenues, gross margins, profitability and cash flows. Correctly identifying key factors affecting business conditions and predicting future events is inherently an uncertain process, and the guidance LLY provides may not ultimately be accurate and has in the past been inaccurate in certain respects, such as the timing of new product manufacturing ramps. The guidance is based on certain assumptions such as those relating to global and local economic conditions, anticipated production and sales volumes (which generally are not linear throughout a given period), average sales prices, supplier and commodity costs, and planned cost reductions. If LLY’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 LLY could decline significantly.

| 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 4% 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 -30.9%. 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 48.1% 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 90.46%. The Underlying Security’s highest volatility rate for any one calendar year during this period was 97.93% and volatility for a shorter period of time may have been substantially higher. The Underlying Security’s annualized performance during this period was 5.52%. Historical Underlying Security volatility and performance are not indications of what Underlying Security volatility and performance will be in the future.

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

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

| Risk [Text Block] | Derivatives Risk. Derivatives are financial instruments that derive value from the underlying reference asset or assets, such as stocks, bonds, or funds (including ETFs), interest rates or indexes. The Fund’s investments in derivatives may pose risks in addition to, and greater than, those associated with directly investing in securities or other ordinary investments, including risk related to the market, leverage, imperfect daily correlations with underlying investments or the Fund’s other portfolio holdings, higher price volatility, lack of availability, counterparty risk, liquidity, valuation and legal restrictions. The use of derivatives is a highly specialized activity that involves investment techniques and risks different from those associated with ordinary portfolio securities transactions. The use of derivatives may result in larger losses or smaller gains than directly investing in securities. When the Fund uses derivatives, there may be imperfect correlation between the share price of the Underlying Security and the derivative, which may prevent the Fund from achieving its investment objective. Because derivatives often require only a limited initial investment, the use of derivatives may expose the Fund to losses in excess of those amounts initially invested.
The Fund will be subject to regulatory constraints relating to level of value at risk that the Fund may incur through its derivative portfolio. To the extent the Fund exceeds these regulatory thresholds over an extended period, the Fund may determine that it is necessary to make adjustments to the Fund’s investment strategy, including the desired daily leveraged performance for the Fund. |

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.

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 Internal Revenue Code of 1986, as amended (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] | MSTR Trading Risk. The trading price of MSTR may be highly volatile and could continue to be subject to wide fluctuations in response to various factors. The stock market in general, and the market for technology companies in particular, has experienced extreme price and volume fluctuations that have often been unrelated or disproportionate to the operating performance of those companies. In particular, a large proportion of MSTR may be traded by short sellers which may put pressure on the supply and demand for the common stock of MSTR, further influencing volatility in its market price. Public perception and other factors outside of the control of MSTR may additionally impact MSTR’s share price due to MSTR garnering a disproportionate degree of public attention, regardless of actual operating performance. In addition, in the past, following periods of volatility in the overall market and the market price of a particular company’s securities, securities class action litigation has often been instituted against companies such as these. Moreover, stockholder litigation like this has been filed against MSTR in the past. While MSTR continues to defend such actions, any judgment against MSTR, or any future stockholder litigation could result in substantial costs and a diversion of the management of MSTR’s attention and resources. If MSTR trading is halted, trading in Shares of the Fund may be impacted, either temporarily or indefinitely.

| Risk [Text Block] | MSTR Performance Risk. MSTR may fail to meet its publicly announced guidelines or other expectations about its business, which could cause the price of MSTR to decline. MSTR provides guidance regarding its expected financial and business performance, such as projections regarding sales and production, as well as anticipated future revenues, gross margins, profitability and cash flows. Correctly identifying key factors affecting business conditions and predicting future events is inherently an uncertain process, and the guidance MSTR provides may not ultimately be accurate and has in the past been inaccurate in certain respects, such as the timing of new product manufacturing ramps. The guidance is based on certain assumptions such as those relating to global and local economic conditions, anticipated production and sales volumes (which generally are not linear throughout a given period), average sales prices, supplier and commodity costs, and planned cost reductions. If MSTR’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 MSTR could decline significantly.

| Risk [Text Block] | Software Industry Risk. 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.

Investing in Bitcoin exposes investors (such as MSTR and, in turn, MSTR shareholders) to significant risks that are not typically present in other investments. These risks include the 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 exchanges, 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.

| 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.
Estimated Returns of 200% or Two Times
The Underlying Security’s annualized historical volatility rate for the five-year period ended June 30, 2026 was 39.09%. The Underlying Security’s highest volatility rate for any one calendar year during this period was 55.14% and volatility for a shorter period of time may have been substantially higher. The Underlying Security’s annualized performance during this period was 2.74%. Historical Underlying Security volatility and performance are not indications of what Underlying Security volatility and performance will be in the future. |

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

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

| Risk [Text Block] | Derivatives Risk. Derivatives are financial instruments that derive value from the underlying reference asset or assets, such as stocks, bonds, or funds (including ETFs), interest rates or indexes. The Fund’s investments in derivatives may pose risks in addition to, and greater than, those associated with directly investing in securities or other ordinary investments, including risk related to the market, leverage, imperfect daily correlations with underlying investments or the Fund’s other portfolio holdings, higher price volatility, lack of availability, counterparty risk, liquidity, valuation and legal restrictions. The use of derivatives is a highly specialized activity that involves investment techniques and risks different from those associated with ordinary portfolio securities transactions. The use of derivatives may result in larger losses or smaller gains than directly investing in securities. When the Fund uses derivatives, there may be imperfect correlation between the share price of the Underlying Security and the derivative, which may prevent the Fund from achieving its investment objective. Because derivatives often require only a limited initial investment, the use of derivatives may expose the Fund to losses in excess of those amounts initially invested.
The Fund will be subject to regulatory constraints relating to level of value at risk that the Fund may incur through its derivative portfolio. To the extent the Fund exceeds these regulatory thresholds over an extended period, the Fund may determine that it is necessary to make adjustments to the Fund’s investment strategy, including the desired daily leveraged performance for the Fund. |

| 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.

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

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

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

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

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

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

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] | 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 Internal Revenue Code of 1986, as amended (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] | Pharmaceutical Industry Risks: Pharmaceutical research and development are very costly and highly uncertain; NVO may not succeed in developing, licensing, or acquiring commercially successful products sufficient in number or value to replace revenues of products that have lost or will lose intellectual property protection or are displaced by competing products or therapies. NVO and NVO’s products face intense competition from multinational pharmaceutical companies, biotechnology companies, and lower-cost generic and biosimilar manufacturers, and such competition could have a material adverse effect on NVO’s business. NVO’s business is subject to increasing government price controls and other public and private restrictions on pricing, reimbursement, and access for NVO’s drugs, which could have a material adverse effect on NVO’s results of operations, reputation or business. Pharmaceutical products can develop safety or efficacy concerns, which could have a material adverse effect on NVO’s revenues, income, and reputation. Further, NVO may not be able to meet higher-than-expected demand or disruption of product supply due to, e.g. geopolitical instability or quality issues, may compromise product availability, ultimately impacting patients and representing a lost commercial opportunity. In addition, there could be risks related to safety and product liability. Competitive pressures, as well as market dynamics and geopolitical, macroeconomic or healthcare crises (e.g. pandemics) could lead to reduced payer ability and willingness to pay causing harm to NVO.

| Risk [Text Block] | NVO Trading Risk. The trading price of the Underlying Security may exhibit volatility and significant fluctuations due to various factors inherent in the semiconductor industry. This sector is susceptible to price and volume fluctuations, which may not always correlate with the companies’ operational performance. Short sellers may exert influence on trading dynamics, potentially impacting supply and demand dynamics and contributing to market price volatility. The Underlying Security’s share price may also be disproportionately affected by public perception and external factors beyond NVO Nordisk’ control, given its prominence in the industry. Such attention can lead to heightened market reactions regardless of NVO Holding’s operational performance. Furthermore, following periods of market volatility, NVO Nordisk and similar companies may face securities class action litigation, diverting management attention and resources. NVO Holding’s historical exposure to such litigation underscores the potential risks, as adverse judgments or future stockholder actions could result in significant costs. Moreover, in the event of a trading halt for the Underlying Security, trading in Shares of the Fund may be impacted, either temporarily or indefinitely.

| Risk [Text Block] | NVO Performance Risk. NVO may fail to meet its publicly announced guidelines or other expectations about its business, which could cause the price of NVO to decline. NVO provides guidance regarding its expected financial and business performance, such as projections regarding sales and production, as well as anticipated future revenues, gross margins, profitability and cash flows. Correctly identifying key factors affecting business conditions and predicting future events is inherently an uncertain process, and the guidance NVO provides may not ultimately be accurate and has in the past been inaccurate in certain respects, such as the timing of new product manufacturing ramps. The guidance is based on certain assumptions such as those relating to global and local economic conditions, anticipated production and sales volumes (which generally are not linear throughout a given period), average sales prices, supplier and commodity costs, and planned cost reductions. If NVO’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 NVO could decline significantly.

| 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 43.31%. The Underlying Security’s highest volatility rate for any one calendar year during this period was 60.28% and volatility for a shorter period of time may have been substantially higher. The Underlying Security’s annualized performance during this period was 51.24%. Historical Underlying Security volatility and performance are not indications of what Underlying Security volatility and performance will be in the future.

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

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

| Risk [Text Block] | Derivatives Risk. Derivatives are financial instruments that derive value from the underlying reference asset or assets, such as stocks, bonds, or funds (including ETFs), interest rates or indexes. The Fund’s investments in derivatives may pose risks in addition to, and greater than, those associated with directly investing in securities or other ordinary investments, including risk related to the market, leverage, imperfect daily correlations with underlying investments or the Fund’s other portfolio holdings, higher price volatility, lack of availability, counterparty risk, liquidity, valuation and legal restrictions. The use of derivatives is a highly specialized activity that involves investment techniques and risks different from those associated with ordinary portfolio securities transactions. The use of derivatives may result in larger losses or smaller gains than directly investing in securities. When the Fund uses derivatives, there may be imperfect correlation between the share price of the Underlying Security and the derivative, which may prevent the Fund from achieving its investment objective. Because derivatives often require only a limited initial investment, the use of derivatives may expose the Fund to losses in excess of those amounts initially invested.
The Fund will be subject to regulatory constraints relating to level of value at risk that the Fund may incur through its derivative portfolio. To the extent the Fund exceeds these regulatory thresholds over an extended period, the Fund may determine that it is necessary to make adjustments to the Fund’s investment strategy, including the desired daily leveraged performance for the Fund. |

| 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.

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. 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 market.

| 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 nber 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. 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 Internal Revenue Code of 1986, as amended (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] | AVGO Trading Risk. The trading price of AVGO may be subject to volatility and could experience wide fluctuations due to various factors. The semiconductors industry, including AVGO, operates within a market that has historically witnessed significant price and volume fluctuations, sometimes unrelated to the companies’ operating performance. Short sellers may also play a significant role in trading AVGO, 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 AVGO’s share price disproportionately, as AVGO often receives heightened public attention regardless of its operational performance. Additionally, following periods of market volatility, companies, including AVGO, have faced securities class action litigation. AVGO has been subject to such litigation in the past and continues to defend against such actions. However, 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 AVGO, trading in shares of related funds may be impacted, either temporarily or indefinitely.

| Risk [Text Block] | AVGO Performance Risk. AVGO may fail to meet its publicly announced guidelines or other expectations about its business, which could cause the price of AVGO to decline. AVGO provides guidance regarding its expected financial and business performance, such as projections regarding sales and production, as well as anticipated future revenues, gross margins, profitability and cash flows. Correctly identifying key factors affecting business conditions and predicting future events is inherently an uncertain process, and the guidance AVGO provides may not ultimately be accurate and has in the past been inaccurate in certain respects, such as the timing of new product manufacturing ramps. The guidance is based on certain assumptions such as those relating to global and local economic conditions, anticipated production and sales volumes (which generally are not linear throughout a given period), average sales prices, supplier and commodity costs, and planned cost reductions. If AVGO’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 AVGO could decline significantly.

Compliance with governmental regulations and trade restrictions may result in significant expenses, and failure to comply could lead to the cessation of product manufacture and distribution, administrative proceedings, and civil or criminal penalties. Global political and economic instability, along with the failure to realize expected benefits from the VMware Merger, further pose challenges. The company also encounters risks related to acquisitions, investments, joint ventures, and dispositions, which could adversely affect financial results. Additionally, dependency on senior management and the ability to attract and retain qualified personnel are critical to executing AVGO’s business strategy effectively.

AVGO is subject to technological and cybersecurity risks, including potential impairments to the confidentiality, integrity, or availability of IT systems and those of corporate infrastructure vendors, which could have a material adverse effect on the business. Operating in the highly cyclical semiconductor industry, AVGO’s sales are largely dependent on a small number of customers, and any reduction in demand or loss of significant customers could adversely affect the business. Reliance on contract manufacturing and suppliers of critical components within the supply chain, along with the need to purchase materials from a limited number of suppliers, may impact AVGO’s ability to bring products to market. Furthermore, failure to adjust manufacturing and supply chains to meet customer demand accurately could adversely affect operational results.

AVGO is involved in various legal proceedings, including intellectual property, securities litigation, and employee-related claims, which could adversely affect the business. The company’s growth in the software segment depends on customer acceptance of newer products and services, and incompatibility with operating environments or third-party products could decrease demand. Failure to enter into satisfactory software license agreements and the availability of licensed third-party software are additional concerns. Environmental, social, and governance (ESG) matters, compliance with privacy and data security laws, and adherence to environmental, health, and safety regulations could increase costs and restrict operations. Rapidly decreasing average selling prices of semiconductor products and fluctuations in foreign exchange rates also pose significant risks.

| Risk [Text Block] | Semiconductor Industry Risks. Semiconductor companies may face intense competition,both domestically and internationally, and such competition may have an adverse effect on their profit margins. Semiconductor companies may have limited product lines, markets, financial resources or personnel. Semiconductor companies’ supply chain and operations are dependent on the availability of materials that meet exacting standards and the use of third parties to provide components and services. Semiconductor companies may rely on a limited number of suppliers, or upon suppliers in a single location, for certain materials, equipment or tools. Finding and qualifying alternate or additional suppliers can be a lengthy process that can cause production delays or impose unforeseen costs, and such alternatives may not be available at all. Production can be disrupted by the unavailability of resources, such as water, silicon, electricity, gases and other materials. Suppliers may also increase prices or encounter cybersecurity or other issues that can disrupt production or increase production costs.
The products of semiconductor companies may face obsolescence due to rapid technological developments and frequent new product introduction, unpredictable changes in growth rates and competition for the services of qualified personnel. Capital equipment expenditures could be substantial, and equipment generally suffers from rapid obsolescence. Companies in the semiconductor industry are heavily dependent on patent and intellectual property rights. The loss or impairment of these rights would adversely affect the profitability of these companies.

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 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 87.04%. The Underlying Security’s highest volatility rate for any one calendar year 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 leveraged correlation to the Underlying Security and therefore achieve its daily leveraged investment objective. To achieve a high degree of leveraged correlation with the Underlying Security, the Fund seeks to rebalance its portfolio daily to keep exposure consistent with its daily leveraged investment objective. The possibility of the Fund being materially over- or under-exposed to the Underlying Security increases on days when the Underlying Security is volatile near the close of the trading day. Market disruptions, regulatory restrictions and extreme volatility will also adversely affect the Fund’s ability to adjust exposure to the required levels. If there is a significant intra-day market event and/or the Underlying Security experiences a significant increase or decline, the Fund may not meet its investment objective, be able to rebalance its portfolio appropriately, or may experience significant premiums or discounts, or widened bid-ask spreads.
The Fund may have difficulty achieving its daily leveraged investment objective due to fees, expenses, transaction costs, financing costs related to the use of derivatives, investments in ETFs, directly or indirectly, income items, valuation methodology, accounting standards and disruptions or illiquidity in the markets for the securities or derivatives held by the Fund. The Fund may be subject to large movements of assets into and out of the Fund, potentially resulting in the Fund being over- or under-exposed to the Underlying Security. The Fund may take or refrain from taking positions to improve the tax efficiency or to comply with various regulatory restrictions, either of which may negatively impact the Fund’s leveraged correlation to the Underlying Security.

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

| Risk [Text Block] | Derivatives Risk. Derivatives are financial instruments that derive value from the underlying reference asset or assets, such as stocks, bonds, or funds (including ETFs), interest rates or indexes. The Fund’s investments in derivatives may pose risks in addition to, and greater than, those associated with directly investing in securities or other ordinary investments, including risk related to the market, leverage, imperfect daily correlations with underlying investments or the Fund’s other portfolio holdings, higher price volatility, lack of availability, counterparty risk, liquidity, valuation and legal restrictions. The use of derivatives is a highly specialized activity that involves investment techniques and risks different from those associated with ordinary portfolio securities transactions. The use of derivatives may result in larger losses or smaller gains than directly investing in securities. When the Fund uses derivatives, there may be imperfect correlation between the share price of the Underlying Security and the derivative, which may prevent the Fund from achieving its investment objective. Because derivatives often require only a limited initial investment, the use of derivatives may expose the Fund to losses in excess of those amounts initially invested.
The Fund will be subject to regulatory constraints relating to level of value at risk that the Fund may incur through its derivative portfolio. To the extent the Fund exceeds these regulatory thresholds over an extended period, the Fund may determine that it is necessary to make adjustments to the Fund’s investment strategy, including the desired daily leveraged performance for the Fund. |

| 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.

| 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.

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 market.

| 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.

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 Internal Revenue Code of 1986, as amended (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 Trading Risk. The trading price of SMCI may demonstrate volatility and wide fluctuations due to various factors inherent in the technology industry. Unlike some other sectors, the technology industry, including SMCI, is prone to significant price and volume fluctuations, occasionally unrelated to operational performance. Short sellers may also play a significant role in trading SMCI, impacting supply and demand dynamics and contributing to market price volatility. Moreover, external factors and public perception may disproportionately influence SMCI’s share price within the technology sector, with heightened public attention notwithstanding operational performance. Furthermore, SMCI, like other tech companies, may encounter securities class action litigation during periods of market volatility, potentially resulting in substantial costs and diverting management’s attention and resources. In the event of a trading halt for SMCI, trading in Shares of the Fund may be impacted, either temporarily or indefinitely.

| Risk [Text Block] | SMCI Performance Risk. SMCI may fail to meet its publicly announced guidelines or other expectations about its business, which could cause the price of SMCI to decline. SMCI provides guidance regarding its expected financial and business performance, such as projections regarding sales and production, as well as anticipated future revenues, gross margins, profitability and cash flows. Correctly identifying key factors affecting business conditions and predicting future events is inherently an uncertain process, and the guidance SMCI provides may not ultimately be accurate and has in the past been inaccurate in certain respects, such as the timing of new product manufacturing ramps. The guidance is based on certain assumptions such as those relating to global and local economic conditions, anticipated production and sales volumes (which generally are not linear throughout a given period), average sales prices, supplier and commodity costs, and planned cost reductions. If SMCI’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 SMCI could decline significantly.

Super Micro Computer, Inc. previously announced that it had received a notification letter from Nasdaq, dated September 17, 2024, indicating that the company was not in compliance with Nasdaq Listing Rule 5250(c)(1), which requires timely filing of periodic reports with the SEC. This notice was triggered by SMCI’s delay in filing its Annual Report on Form 10-K for the fiscal year ended June 30, 2024. On February 25, 2025, SMCI filed its Form 10-K, along with its Quarterly Reports on Form 10-Q for the first and second quarters of its fiscal year 2025, thereby regaining compliance with Nasdaq’s reporting requirements. While SMCI is currently in good standing with respect to Nasdaq listing standards, there can be no assurance that it will continue to meet its reporting obligations in a timely manner in the future. Any future failure to comply with Nasdaq’s listing requirements, including timely filings, could result in SMCI’s common stock being delisted from Nasdaq, which would prevent the Fund from continuing to operate.

| Risk [Text Block] | Technology Hardware, Storage &Peripherals Industry Risk.Technology hardware, storage and peripherals companies can be significantly affected by competitive pressures, aggressive pricing, technological developments, changing domestic demand, the ability to attract and retain skilled employees and availability and price of components. The market for products produced by these companies is characterized by rapidly changing technology, rapid product obsolescence, cyclical market patterns, evolving industry standards and frequent new product introductions. The success of technology hardware companies depends in substantial part on the timely and successful introduction of new products. An unexpected change in one or more of the technologies affecting an issuer’s products or in the market for products based on a particular technology could have a material adverse effect on a participant’s operating results.
Many of these companies rely on a combination of patents, copyrights, trademarks and trade secret laws to establish and protect their proprietary rights in their products and technologies. There can be no assurance that the steps taken by the companies to protect their proprietary rights will be adequate to prevent misappropriation of their technology or that competitors will not independently develop technologies that are substantially equivalent or superior to such companies’ technology.

| 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 Target Portfolio’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 the Target Portfolio, if adverse daily performance of the Target Portfolio 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 Target Portfolio 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 Target Portfolio’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 Target Portfolio during a shareholder’s holding period of an investment in the Fund.
The chart below provides examples of how the Target Portfolio’s volatility could affect the Fund’s performance. The chart illustrates the impact of two factors that affect the Fund’s performance – the Target Portfolio’s volatility and the Target Portfolio’s performance. The Target Portfolio’s performance shows the percentage change in the share price of the Target Portfolio over the specified time period, while the Target Portfolio’s volatility is a statistical measure of the magnitude of fluctuations in the returns during that time period. As illustrated below, even if the Target Portfolio’s performance over two equal time periods is identical, different Target Portfolio volatility (i.e., in magnitude of fluctuations in the share price of the Target Portfolio) 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 Target Portfolio volatility; b) the Target Portfolio 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 Target Portfolio volatility and Target Portfolio 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 Target Portfolio volatility, compounding will cause results for periods longer than a trading day to vary from two times (200%) the performance of the Target Portfolio.
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 Target Portfolio over a one-year period during which the Target Portfolio experienced annualized volatility of 25%. If the Target Portfolio’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 Target Portfolio. For instance, if the Target Portfolio’s annualized volatility is 100%, the Fund would be expected to lose 63.2% of its value, even if the cumulative Target Portfolio change in the share price of the Target Portfolio 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 Target Portfolio 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 Target Portfolio. 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.
Since market volatility has negative implications for the Fund which rebalances its derivatives daily, investors should be sure to monitor and manage their investments in the Fund particularly in volatile markets. The negative implications of volatility in Table 1 can be combined with the recent volatility ranges of the then-current Target Portfolio’s historical volatility, which are expected to be high. Historical volatility and performance for the Target Portfolio are not likely indicative of future volatility and performance.

| Risk [Text Block] | Daily Correlation/Tracking Risk. There is no guarantee that the Fund will achieve a high degree of leveraged correlation to the Target Portfolio and therefore achieve its daily leveraged investment objective. To achieve a high degree of leveraged correlation with the Target Portfolio, 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 Target Portfolio increases on days when the Target Portfolio is volatile near the close of the trading day. Additionally, if securities within the Target Portfolio exhibit unexpected or heightened correlations, the Fund’s ability to achieve its daily investment objective may be adversely impacted as overlapping exposures may reduce potential diversification benefits and amplify the effects of market movements. 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 Target Portfolio 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 also be impacted by large movements of assets into and out of the Fund, potentially resulting in the Fund being over- or under-exposed to the Target Portfolio. 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 Target Portfolio. Finally, during periods of high volatility, compounding effects and correlation shifts between securities in the Target Portfolio may cause the Fund’s returns to deviate materially from two times (2X) the daily performance of the Target Portfolio.

| 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 Target Portfolio 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 Target Portfolio, 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 Target Portfolio declines more than 50%. Leverage will also have the effect of magnifying any differences in the Fund performance’s correlation with the Target Portfolio’s share price.

| Risk [Text Block] | Derivatives Risk. Derivatives are financial instruments that derive value from the underlying reference asset or assets, such as stocks, bonds, or funds (including ETFs), interest rates or indexes. The Fund’s investments in derivatives may pose risks in addition to, and greater than, those associated with directly investing in securities or other ordinary investments, including risk related to the market, leverage, imperfect daily correlations with underlying investments or the Fund’s other portfolio holdings, higher price volatility, lack of availability, counterparty risk, liquidity, valuation and legal restrictions. The use of derivatives is a highly specialized activity that involves investment techniques and risks different from those associated with ordinary portfolio securities transactions. The use of derivatives may result in larger losses or smaller gains than directly investing in securities. When the Fund uses derivatives, there may be imperfect correlation between the share price of the Target Portfolio 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 Target Portfolio, 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 Target Portfolio 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 Target Portfolio 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 Target Portfolio. 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 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 Target Portfolio 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 market value of the Target Portfolio at the market close on the first trading day and the market value of the Target Portfolio at the time of purchase. If the market value of the Target Portfolio rises, the Fund’s net assets will rise by approximately twice the amount as the Fund’s exposure. Conversely, if the market value of the Target Portfolio 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 Target Portfolio.
If there is a significant intra-day market event and/or the securities of the Target Portfolio 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 Target Portfolio 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. 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 Target Portfolio. 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 Target Portfolio 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 Target Portfolio. There is no assurance that a security that is deemed liquid when purchased will continue to be liquid. Market illiquidity may cause losses for the Fund.

The Fund 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. In order to qualify for the favorable tax treatment generally available to regulated investment companies, the Fund must satisfy certain diversification and other requirements. In particular, the Fund generally may not acquire a security if, as a result of the acquisition, more than 50% of the value of the Fund’s assets would be invested in (a) issuers in which the Fund has, in each case, invested more than 5% of the Fund’s assets and (b) issuers more than 10% of whose outstanding voting securities are owned by the Fund. The application of these requirements to certain investments (including swaps) that may be entered into by the Fund is unclear. In addition, the application of these requirements to the Fund’s investment objective is not clear. If the Fund were to fail to qualify as a regulated investment company, it would be taxed in the same manner as an ordinary corporation, and distributions to its shareholders would not be deductible by the Fund in computing its taxable income.

| Risk [Text Block] | Foreign Securities Risk. Investments in securities or other instruments of non-U.S. issuers involve certain risks not involved in domestic investments and may experience more rapid and extreme changes in value than investments in securities of U.S. companies. Financial markets in foreign countries often are not as developed, efficient, or liquid as financial markets in the United States, and therefore, the prices of non-U.S. securities and instruments can be more volatile. In addition, the Fund will be subject to risks associated with adverse political and economic developments in foreign countries, which may include the imposition of economic sanctions. Generally, there is less readily available and reliable information about non-U.S. issuers due to less rigorous disclosure or accounting standards and regulatory practices.

| Risk [Text Block] | Quantum Computing Industry Risk. The quantum computing industry may be significantly affected by intense competition, aggressive pricing dynamics, rapid technological advancements, and the risk of product obsolescence. Companies in this industry 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. Companies in the quantum computing sector 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.

ADRs listed on U.S. exchanges are issued by banks or trust companies, and entitle the holder to all dividends and capital gains that are paid out on the underlying foreign shares (Underlying Shares). When the Fund invests in ADRs as a substitute for an investment directly in the Underlying Shares, the Fund is exposed to the risk that the ADRs may not provide a return that corresponds precisely with that of the Underlying Shares. Investment in ADRs may be less liquid than the Underlying Shares in their primary trading market.
