| Risk [Text Block] | PRINCIPAL RISKS OF INVESTING IN THE FUND
As with all ETFs, there is the risk that you could lose money through your investment in the Fund. Many factors affect the Fund’s NAV and performance.

| Risk [Text Block] | Underlying Stock Risk: The performance of the Underlying Stock, and consequently the Fund’s performance, is subject to the risks of the electronic data processing industry. Any data breaches, unauthorized access, data loss due to system malfunctions, cyberattacks, privacy violations, data integrity issues, system outages, hardware failures, software vulnerabilities, human error, and power disruptions; essentially, any threat that could compromise the confidentiality, integrity, or availability of stored or processed data could have a material adverse effect on our company, its prospects and financial performance. Worldwide economic conditions could have an effect on the demand for our company’s services and products and could result in declining revenue and earnings. General economic declines or a softening of the economy make it more likely that our company may experience difficulties collecting accounts receivable, sales and demand for our company’s products may decrease, and our company’s operating results may be adversely affected. The Fund’s daily returns may be affected by many factors but will depend on the performance and volatility of the Underlying Stock.

| Risk [Text Block] | Effects of Compounding and Market Volatility Risk: The Fund aims to replicate the daily leverage returns of the Underlying Stock 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 Underlying Stock’s performance, before fees and expenses. Compounding affects all investments but has a more significant impact on funds that aims to replicate leverage daily returns. For a Fund aiming to replicate 2 times the daily performance of an Underlying Stock, if adverse daily performance of the Underlying Stock 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 the favorable daily performance of the Underlying Stock 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 pronounced as the Underlying Stock 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 Stock during the shareholder’s holding period of an investment in the Fund.
The chart below provides examples of how Underlying Stock volatility could affect the Fund’s performance. Fund performance for periods greater than one single day can be estimated given any set of assumptions for the following factors: a) Underlying Stock volatility; b) Underlying Stock’s performance; c) period of time; d) financing rates associated with leveraged exposure; e) other Fund expenses; and f) the Underlying Stock’s dividends. The chart below illustrates the impact of two principal factors – Underlying Stock volatility and performance – on Fund performance. The chart shows estimated Fund returns for a number of combinations of Underlying Stock volatility and performance over a one-year period. Performance shown in the chart assumes that (i) there were no Fund expenses; and (ii) borrowing rates (needed to obtain a leveraged long exposure) of 0%. If Fund expenses and/or actual borrowing/lending rates were reflected, the estimated returns would be lower than those shown. Particularly during periods of higher Underlying Stock volatility, compounding will cause results for periods longer than a trading day to vary from the performance of the Underlying Stock.
As shown in the chart below, the Fund would be expected to lose 6.0% if the Underlying Stock provided no return over a one-year period during which the Underlying Stock experienced annualized volatility of 25%. At higher ranges of volatility, there is a chance of a significant loss of value in the Fund, even if the Underlying Stock return is flat.
For instance, if the Underlying Stock’s annualized volatility is 100%, the Fund would be expected to lose 63.3% of its value, even if the cumulative Underlying Stock’s return for the year was 0%. Areas shaded red (or dark gray) represent those scenarios where the Fund can be expected to return less than 200% of the performance of the Underlying Stock and those shaded green (or light gray) represent those scenarios where the Fund can be expected to return more than 200% of the performance of the Underlying Stock. The Fund’s actual returns may be significantly better or worse than the returns shown below as a result of any of the factors discussed above or in “Tracking Error Risk” below.
The Underlying Stock’s annualized historical volatility rate from January 04, 2021 (Underlying Stock’s IPO date) to August 31, 2025, was 98.8%. During the period observed the Underlying Stock’s highest volatility rate over a 12-month period was 123.8% and volatility for a shorter period of time may have been substantially higher. The Underlying Stock’s annualized performance for the period considered was 34.4%. Historical volatility and performance are not indications of what the Underlying Stock volatility and performance will be in the future. The volatility of instruments that reflect the value of the Underlying Stock, such as swaps, may differ from the volatility of the Underlying Stock.

| Prospectus [Line Items] | ||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||
| Risk [Text Block] | Correlation Risk: A number of factors may affect the Fund’s ability to achieve a high degree of correlation with Underlying Stock, and there is no guarantee that the Fund will achieve a high degree of correlation. Failure to achieve a high degree of correlation may prevent the Fund from achieving its investment objective, and the percentage change of the Fund’s NAV each day may differ, perhaps significantly in amount, and possibly even direction, from 200% of the percentage change of Underlying Stock on such day.
In order to achieve a high degree of correlation with Underlying Stock, the Fund seeks to rebalance its portfolio daily to keep exposure consistent with its investment objective. Being materially under- or overexposed to Underlying Stock may prevent the Fund from achieving a high degree of correlation with Underlying Stock and may expose the Fund to greater leverage risk. Market disruptions or closure, regulatory restrictions, market volatility, illiquidity in the markets for the financial instruments in which the Fund invests, and other factors will adversely affect the Fund’s ability to adjust exposure to requisite levels. The target amount of portfolio exposure is impacted dynamically by Underlying Stock’s movements, including intraday movements. Because of this, it is unlikely that the Fund will have perfect 200% exposure during the day or at the end of each day and the likelihood of being materially under- or overexposed is higher on days when Underlying Stock is volatile, particularly when Underlying Stock is volatile at or near the close of the trading day.
A number of other factors may also adversely affect the Fund’s correlation with Underlying Stock, including fees, expenses, transaction costs, financing costs associated with the use of derivatives, income items, valuation methodology, accounting standards and disruptions or illiquidity in the markets for the securities or financial instruments in which the Fund invests. The Fund may take or refrain from taking positions in order to improve tax efficiency, comply with regulatory restrictions, or for other reasons, each of which may negatively affect the Fund’s correlation with Underlying Stock. The Fund may also be subject to large movements of assets into and out of the Fund, potentially resulting in the Fund being under- or overexposed to Underlying Stock. Additionally, the Fund’s underlying investments and/or reference assets may trade on markets that may not be open on the same day as the Fund, which may cause a difference between the changes in the daily performance of the Fund and changes in the performance of Underlying Stock. Any of these factors could decrease correlation between the performance of the Fund and Underlying Stock and may hinder the Fund’s ability to meet its daily investment objective on or around that day.

| Prospectus [Line Items] | ||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||
| 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 Stock 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 Underlying Stock, 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 Underlying Stock declines more than 50%. Leverage will also have the effect of magnifying any differences in the Fund performance’s correlation with the Underlying Stock.
Due to the limited availability of necessary investments or financial instruments, the Fund could, among other things, as a defensive measure, limit or suspend creations or redemptions of Creation Units until the adviser determines that the requisite exposure to the underlying Stock is obtainable. During the period that creation or redemptions are affected, the Fund’s shares could trade at a significant premium or discount to their net asset value, or the bid-ask spread of the Fund’s shares could widen significantly. In the case of a period during which creations are suspended, the Fund could experience significant redemptions, which may cause the Fund to sell portfolio securities at unfavorable prices and increased transaction and other costs and make greater taxable distributions to shareholders of the Fund.

| Risk [Text Block] | Counterparty Risk: A counterparty (the other party to a transaction or an agreement or the party with whom the Fund executes transactions) to a transaction (including repurchase transaction) with the Fund may be unable or unwilling to make timely principal, interest or settlement payments, or otherwise honor its obligations.

| Risk [Text Block] | Derivatives Risk: The use of derivative instruments involves risks different from, or possibly greater than, the risks associated with investing directly in securities and other traditional investments. These risks include (i) the risk that the counterparty to a derivative transaction may not fulfill its contractual obligations; (ii) risk of mispricing or improper valuation; and (iii) the risk that changes in the value of the derivative may not correlate perfectly with the underlying asset, rate or index. Derivative prices are highly volatile and may fluctuate substantially during a short period of time. Such prices are influenced by numerous factors that affect the markets, including, but not limited to: changing supply and demand relationships; government programs and policies; national and international political and economic events, changes in interest rates, inflation and deflation and changes in supply and demand relationships. Trading derivative instruments involves risks different from, or possibly greater than, the risks associated with investing directly in securities.

| Risk [Text Block] | Exchange Traded Fund Structure Risk: The Fund is structured as an exchange traded fund and as a result is subject to special risks, including:
The Fund will be subject to regulatory constraints relating to the 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 leverage performance for the Fund.

| 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] | Market and Geopolitical Risk: The increasing interconnectivity between global economies and financial markets increases the likelihood that events or conditions in one region or financial market may adversely impact issuers in a different country, region or financial market. Securities in the Fund’s portfolio may underperform due to inflation (or expectations for inflation), interest rates, global demand for particular products or resources, natural disasters, pandemics, epidemics, terrorism, regulatory events and governmental or quasi-governmental actions. The occurrence of global events similar to those in recent years, such as terrorist attacks around the world, natural disasters, social and political discord or debt crises and downgrades, among others, may result in market volatility and may have long term effects on both the U.S. and global financial markets. It is difficult to predict when similar events affecting the U.S. or global financial markets may occur, the effects that such events may have and the duration of those effects.

| Risk [Text Block] | Swap Risk: Swaps are subject to tracking risk because they may not be perfect substitutes for the instruments they are intended to hedge or replace. Over the counter swaps are subject to counterparty default. Leverage inherent in derivatives will tend to magnify the Fund’s losses.

| Prospectus [Line Items] | ||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||
| Risk [Text Block] | Options Contracts Risk: The use of options contracts involves investment strategies and risks different from those associated with ordinary portfolio securities transactions. The prices of options are volatile and are influenced by, among other things, actual and anticipated changes in the value of the underlying instrument, including the anticipated volatility, which are affected by fiscal and monetary policies and by national and international political, changes in the actual or implied volatility or the reference asset, the time remaining until the expiration of the option contract and economic events. For the Fund, in particular, the value of the options contracts in which it invests is substantially influenced by the value of the Underlying Stock. The Fund may experience substantial downside from specific option positions and certain option positions held by the Fund may expire worthless. As an option approaches its expiration date, its value typically increasingly moves with the value of the underlying instrument. However, prior to such a date, the value of an option generally does not increase or decrease at the same rate at the underlying instrument. There may at times be an imperfect correlation between the movement in values of 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. Furthermore, when the Fund seeks to trade out of positions, especially near expiration, there is an added risk that the Fund may be required to allocate resources unexpectedly to fulfill these obligations. This potential exposure to physical settlement can significantly impact the Fund’s liquidity and market exposure, particularly in volatile market conditions. If the Fund sells non-cash settled options contracts, it would be obligated to receive shares of the Underlying Stock when the option is exercised. Consequently, there is a risk that the Fund may have to physically acquire the Underlying Stock shares at the strike price, which could result in the Fund holding the Underlying Stock, and an asset that has declined in value. The level of exposure obtained through option contracts should at most be equal to the Fund’s Daily Leverage Factor times the Fund’s net asset value.

| 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 Stock that is significantly greater or less than its stated multiple. As a result, the Fund may be more exposed to leverage risk than if it had been properly rebalanced and may not achieve its investment objective.

| Risk [Text Block] | Trading Halt Risk: Although the Underlying Stock’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 Stock’s shares is expected, in turn, to result in a halt in the trading in the Fund’s shares. Trading in the Underlying Stock’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 Underling Stock’s and/or Fund’s shares inadvisable. In addition, trading in Underlying Stock’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] | Tracking Error Risk: Tracking error is the divergence of the Fund’s performance from that of its investment objective which aims to replicate 2 times the daily percentage change of the Underlying Stock. The performance of the Fund may diverge from that of its investment objective 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 Stock 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 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] | US Treasury Risk: U.S. Treasury obligations are backed by the “full faith and credit” of the U.S. government and generally have negligible credit risk. Securities issued or guaranteed by federal agencies or authorities and U.S. government-sponsored instrumentalities or enterprises may or may not be backed by the full faith and credit of the U.S. government. The Fund may be subject to such risk to the extent it invests in securities issued or guaranteed by federal agencies or authorities and U.S. government-sponsored instrumentalities or enterprises.

| 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, particularly because the Fund’s investment objective focuses on the performance of the stock of a single issuer. 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] | Underlying Stock Risk: The Underlying Stock is subject to many risks that can negatively impact its revenue and viability including, but are not limited to price volatility risk, management risk, inflation risk, global economic risk, growth risk, supply and demand risk, operations risk, regulatory risk, environmental risk, terrorism risk and the risk of natural disasters. The Underlying Stock performance may be affected by competition in the microprocessor market, reliance on third-party manufacturers, the company’s ability to new develop new products, losses of significant customers, changes in customer demand for its products, risks associated with defective products political, legal and economic risks affecting the company’s global operations. The Fund’s daily returns may be affected by many factors but will depend on the performance and volatility of the Underlying Stock.
The Underlying Stock may also be impacted by many factors, including but not limited to, government regulations, economic conditions, credit rating downgrades, changes in interest rates and decreased liquidity in credit markets. Profitability of the Underlying Stock may be dependent on the availability and cost of capital and can fluctuate significantly when interest rates change. Credit losses resulting from financial difficulties of borrowers also can negatively impact the Underlying Stock. The Underlying Stock is also subject to substantial government regulations and intervention, which may adversely impact the scope of its activities, the prices it can charges, the amount of capital it must maintain, and potentially, its size. Government regulation may change frequently and may have significant adverse consequences for the Underlying Stock, including effects that are not intended by such regulation. The impact of more stringent capital requirements, or recent or future regulations in various countries on any individual financial company or of the financial sector as a whole, cannot be predicted. The financials sector is also a target for cyber-attacks and may experience technological malfunctions and disruptions, which have occurred more frequently in recent years.

| Prospectus [Line Items] | ||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||
| Risk [Text Block] | Effects of Compounding and Market Volatility Risk: The Fund aims to replicate the daily leverage returns of the Underlying Stock 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 Underlying Stock’s performance, before fees and expenses. Compounding affects all investments but has a more significant impact on funds that aims to replicate leverage daily returns. For a Fund aiming to replicate 2 times the daily performance of an Underlying Stock, if adverse daily performance of the Underlying Stock 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 the favorable daily performance of the Underlying Stock 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 pronounced as the Underlying Stock 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 Stock during the shareholder’s holding period of an investment in the Fund.
The chart below provides examples of how Underlying Stock volatility could affect the Fund’s performance. Fund performance for periods greater than one single day can be estimated given any set of assumptions for the following factors: a) Underlying Stock volatility; b) Underlying Stock’s performance; c) period of time; d) financing rates associated with leveraged exposure; e) other Fund expenses; and f) the Underlying Stock’s dividends. The chart below illustrates the impact of two principal factors – Underlying Stock volatility and performance – on Fund performance. The chart shows estimated Fund returns for a number of combinations of Underlying Stock volatility and performance over a one-year period. Performance shown in the chart assumes that (i) there were no Fund expenses; and (ii) borrowing rates (needed to obtain a leveraged long exposure) of 0%. If Fund expenses and/or actual borrowing/lending rates were reflected, the estimated returns would be lower than those shown. Particularly during periods of higher Underlying Stock volatility, compounding will cause results for periods longer than a trading day to vary from the performance of the Underlying Stock.
As shown in the chart below, the Fund would be expected to lose 6.0% if the Underlying Stock provided no return over a one-year period during which the Underlying Stock experienced annualized volatility of 25%. At higher ranges of volatility, there is a chance of a significant loss of value in the Fund, even if the Underlying Stock return is flat.
For instance, if the Underlying Stock’s annualized volatility is 100%, the Fund would be expected to lose 63.3% of its value, even if the cumulative Underlying Stock’s return for the year was 0%. Areas shaded red (or dark gray) represent those scenarios where the Fund can be expected to return less than 200% of the performance of the Underlying Stock and those shaded green (or light gray) represent those scenarios where the Fund can be expected to return more than 200% of the performance of the Underlying Stock. The Fund’s actual returns may be significantly better or worse than the returns shown below as a result of any of the factors discussed above or in “Tracking Error Risk” below.
The Underlying Stock’s annualized historical volatility rate for the five-year period ended August 31, 2025, was 62.3%. During the five-year period observed the Underlying Stock’s highest volatility rate over a 12-month period was 83.3% and volatility for a shorter period of time may have been substantially higher. The Underlying Stock’s annualized performance for the five-year period ended August 31, 2025, was -13.7%. Historical volatility and performance are not indications of what the Underlying Stock volatility and performance will be in the future. The volatility of instruments that reflect the value of the Underlying Stock, such as swaps, may differ from the volatility of the Underlying Stock.

| Risk [Text Block] | Correlation Risk: A number of factors may affect the Fund’s ability to achieve a high degree of correlation with Underlying Stock, and there is no guarantee that the Fund will achieve a high degree of correlation. Failure to achieve a high degree of correlation may prevent the Fund from achieving its investment objective, and the percentage change of the Fund’s NAV each day may differ, perhaps significantly in amount, and possibly even direction, from 200% of the percentage change of Underlying Stock on such day.
In order to achieve a high degree of correlation with Underlying Stock, the Fund seeks to rebalance its portfolio daily to keep exposure consistent with its investment objective. Being materially under- or overexposed to Underlying Stock may prevent the Fund from achieving a high degree of correlation with Underlying Stock and may expose the Fund to greater leverage risk. Market disruptions or closure, regulatory restrictions, market volatility, illiquidity in the markets for the financial instruments in which the Fund invests, and other factors will adversely affect the Fund’s ability to adjust exposure to requisite levels. The target amount of portfolio exposure is impacted dynamically by Underlying Stock’s movements, including intraday movements. Because of this, it is unlikely that the Fund will have perfect 200% exposure during the day or at the end of each day and the likelihood of being materially under- or overexposed is higher on days when Underlying Stock is volatile, particularly when Underlying Stock is volatile at or near the close of the trading day.
A number of other factors may also adversely affect the Fund’s correlation with Underlying Stock, including fees, expenses, transaction costs, financing costs associated with the use of derivatives, income items, valuation methodology, accounting standards and disruptions or illiquidity in the markets for the securities or financial instruments in which the Fund invests. The Fund may take or refrain from taking positions in order to improve tax efficiency, comply with regulatory restrictions, or for other reasons, each of which may negatively affect the Fund’s correlation with Underlying Stock. The Fund may also be subject to large movements of assets into and out of the Fund, potentially resulting in the Fund being under- or overexposed to Underlying Stock. Additionally, the Fund’s underlying investments and/or reference assets may trade on markets that may not be open on the same day as the Fund, which may cause a difference between the changes in the daily performance of the Fund and changes in the performance of Underlying Stock. Any of these factors could decrease correlation between the performance of the Fund and Underlying Stock and may hinder the Fund’s ability to meet its daily investment objective on or around that day.

| 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 Stock 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 Underlying Stock, 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 Underlying Stock declines more than 50%. Leverage will also have the effect of magnifying any differences in the Fund performance’s correlation with the Underlying Stock.
Due to the limited availability of necessary investments or financial instruments, the Fund could, among other things, as a defensive measure, limit or suspend creations or redemptions of Creation Units until the adviser determines that the requisite exposure to the underlying Stock is obtainable. During the period that creation or redemptions are affected, the Fund’s shares could trade at a significant premium or discount to their net asset value, or the bid-ask spread of the Fund’s shares could widen significantly. In the case of a period during which creations are suspended, the Fund could experience significant redemptions, which may cause the Fund to sell portfolio securities at unfavorable prices and increased transaction and other costs and make greater taxable distributions to shareholders of the Fund.

| Risk [Text Block] | Derivatives Risk: The use of derivative instruments involves risks different from, or possibly greater than, the risks associated with investing directly in securities and other traditional investments. These risks include (i) the risk that the counterparty to a derivative transaction may not fulfill its contractual obligations; (ii) risk of mispricing or improper valuation; and (iii) the risk that changes in the value of the derivative may not correlate perfectly with the underlying asset, rate or index. Derivative prices are highly volatile and may fluctuate substantially during a short period of time. Such prices are influenced by numerous factors that affect the markets, including, but not limited to: changing supply and demand relationships; government programs and policies; national and international political and economic events, changes in interest rates, inflation and deflation and changes in supply and demand relationships. Trading derivative instruments involves risks different from, or possibly greater than, the risks associated with investing directly in securities.

The Fund will be subject to regulatory constraints relating to the 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 leverage performance for the Fund.

| 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] | Market and Geopolitical Risk: The increasing interconnectivity between global economies and financial markets increases the likelihood that events or conditions in one region or financial market may adversely impact issuers in a different country, region or financial market. Securities in the Fund’s portfolio may underperform due to inflation (or expectations for inflation), interest rates, global demand for particular products or resources, natural disasters, pandemics, epidemics, terrorism, regulatory events and governmental or quasi-governmental actions. The occurrence of global events similar to those in recent years, such as terrorist attacks around the world, natural disasters, social and political discord or debt crises and downgrades, among others, may result in market volatility and may have long term effects on both the U.S. and global financial markets. It is difficult to predict when similar events affecting the U.S. or global financial markets may occur, the effects that such events may have and the duration of those effects.

| Prospectus [Line Items] | ||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||
| Risk [Text Block] | Options Contracts Risk: The use of options contracts involves investment strategies and risks different from those associated with ordinary portfolio securities transactions. The prices of options are volatile and are influenced by, among other things, actual and anticipated changes in the value of the underlying instrument, including the anticipated volatility, which are affected by fiscal and monetary policies and by national and international political, changes in the actual or implied volatility or the reference asset, the time remaining until the expiration of the option contract and economic events. For the Fund, in particular, the value of the options contracts in which it invests is substantially influenced by the value of the Underlying Stock. The Fund may experience substantial downside from specific option positions and certain option positions held by the Fund may expire worthless. As an option approaches its expiration date, its value typically increasingly moves with the value of the underlying instrument. However, prior to such a date, the value of an option generally does not increase or decrease at the same rate at the underlying instrument. There may at times be an imperfect correlation between the movement in values of 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. Furthermore, when the Fund seeks to trade out of positions, especially near expiration, there is an added risk that the Fund may be required to allocate resources unexpectedly to fulfill these obligations. This potential exposure to physical settlement can significantly impact the Fund’s liquidity and market exposure, particularly in volatile market conditions. If the Fund sells non-cash settled options contracts, it would be obligated to receive shares of the Underlying Stock when the option is exercised. Consequently, there is a risk that the Fund may have to physically acquire the Underlying Stock shares at the strike price, which could result in the Fund holding the Underlying Stock, and an asset that has declined in value. The level of exposure obtained through option contracts should at most be equal to the Fund’s Daily Leverage Factor times the Fund’s net asset value.

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

| Risk [Text Block] | Trading Halt Risk: Although the Underlying Stock’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 Stock’s shares is expected, in turn, to result in a halt in the trading in the Fund’s shares. Trading in the Underlying Stock’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 Underling Stock’s and/or Fund’s shares inadvisable. In addition, trading in Underlying Stock’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] | Tracking Error Risk: Tracking error is the divergence of the Fund’s performance from that of its investment objective which aims to replicate 2 times the daily percentage change of the Underlying Stock. The performance of the Fund may diverge from that of its investment objective 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 Stock 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 as a result of market restrictions or other legal reasons, including regulatory limits or other restrictions on securities that may be purchased by the Adviser and its affiliates.

| Risk [Text Block] | Tax Risk: 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, particularly because the Fund’s investment objective focuses on the performance of the stock of a single issuer. 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] | Underlying Stock Risk: The performance of the Underlying Stock, and consequently the Fund’s performance, is subject to the risks of the electronic data processing industry. Any data breaches, unauthorized access, data loss due to system malfunctions, cyberattacks, privacy violations, data integrity issues, system outages, hardware failures, software vulnerabilities, human error, and power disruptions; essentially, any threat that could compromise the confidentiality, integrity, or availability of stored or processed data could have a material adverse effect on our company, its prospects and financial performance. Worldwide economic conditions could have an effect on the demand for our company’s services and products and could result in declining revenue and earnings. General economic declines or a softening of the economy make it more likely that our company may experience difficulties collecting accounts receivable, sales and demand for our company’s products may decrease, and our company’s operating results may be adversely affected. The Fund’s daily returns may be affected by many factors but will depend on the performance and volatility of the Underlying Stock.

| Prospectus [Line Items] | ||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||
| Risk [Text Block] | Effects of Compounding and Market Volatility Risk: The Fund’s aims to replicate the leveraged daily returns of the Underlying Stock 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 the Underlying Stock’s performance, before fees and expenses. Compounding affects all investments but has a more significant impact on funds that aims to replicate leverage daily returns. For a Fund aiming to replicate 2 times the daily performance of an Underlying Stock, if adverse daily performance of the Underlying Stock 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 the favorable daily performance of the Underlying Stock 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 pronounced as the Underlying Stock 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 Stock during the shareholder’s holding period of an investment in the Fund.
The chart below provides examples of how Underlying Stock volatility could affect the Fund’s performance. Fund performance for periods greater than one single day can be estimated given any set of assumptions for the following factors: a) Underlying Stock volatility; b) Underlying Stock’s performance; c) period of time; d) financing rates associated with leveraged exposure; e) other Fund expenses; and f) the Underlying Stock’s dividends. The chart below illustrates the impact of two principal factors – Underlying Stock volatility and performance – on Fund performance.
The chart shows estimated Fund returns for a number of combinations of Underlying Stock volatility and performance over a one-year period. Performance shown in the chart assumes that (i) there were no Fund expenses; and (ii) borrowing rates (needed to obtain a leveraged long exposure) of 0%. If Fund expenses and/or actual borrowing/lending rates were reflected, the estimated returns would be lower than those shown. Particularly during periods of higher Underlying Stock volatility, compounding will cause results for periods longer than a trading day to vary from the performance of the Underlying Stock.
As shown in the chart below, the Fund would be expected to lose 6.0% if the Underlying Stock provided no return over a one-year period during which the Underlying Stock experienced annualized volatility of 25%. At higher ranges of volatility, there is a chance of a significant loss of value in the Fund, even if the Underlying Stock return is flat.
For instance, if the Underlying Stock annualized volatility is 100%, the Fund would be expected to lose 63.3% of its value, even if the cumulative Underlying Stock return for the year was 0%. Areas shaded red (or dark gray) represent those scenarios where the Fund can be expected to return less than 200% of the performance of the Underlying Stock and those shaded green (or light gray) represent those scenarios where the Fund can be expected to return more than 200% of the performance of the Underlying Stock. The Fund’s actual returns may be significantly better or worse than the returns shown below as a result of any of the factors discussed above or in “Tracking Error Risk” below.
The Underlying Stock’s annualized historical volatility rate for the five-year period ended August 31, 2025, was 125.2%. During the period observed the Underlying Stock’s highest volatility rate over a 12-month period was 166.7% and volatility for a shorter period of time may have been substantially higher. The Underlying Stock’s annualized performance for the five-year period ended August 31, 2025, was 44.4%. Historical volatility and performance are not indications of what the Underlying Stock volatility and performance will be in the future. The volatility of instruments that reflect the value of the Underlying Stock, such as swaps, may differ from the volatility of the Underlying Stock.

| Risk [Text Block] | Correlation Risk: A number of factors may affect the Fund’s ability to achieve a high degree of correlation with Underlying Stock, and there is no guarantee that the Fund will achieve a high degree of correlation. Failure to achieve a high degree of correlation may prevent the Fund from achieving its investment objective, and the percentage change of the Fund’s NAV each day may differ, perhaps significantly in amount, and possibly even direction, from 200% of the percentage change of Underlying Stock on such day.
In order to achieve a high degree of correlation with Underlying Stock, the Fund seeks to rebalance its portfolio daily to keep exposure consistent with its investment objective. Being materially under- or overexposed to Underlying Stock may prevent the Fund from achieving a high degree of correlation with Underlying Stock and may expose the Fund to greater leverage risk. Market disruptions or closure, regulatory restrictions, market volatility, illiquidity in the markets for the financial instruments in which the Fund invests, and other factors will adversely affect the Fund’s ability to adjust exposure to requisite levels. The target amount of portfolio exposure is impacted dynamically by Underlying Stock’s movements, including intraday movements. Because of this, it is unlikely that the Fund will have perfect 200% exposure during the day or at the end of each day and the likelihood of being materially under- or overexposed is higher on days when Underlying Stock is volatile, particularly when Underlying Stock is volatile at or near the close of the trading day.
A number of other factors may also adversely affect the Fund’s correlation with Underlying Stock, including fees, expenses, transaction costs, financing costs associated with the use of derivatives, income items, valuation methodology, accounting standards and disruptions or illiquidity in the markets for the securities or financial instruments in which the Fund invests. The Fund may take or refrain from taking positions in order to improve tax efficiency, comply with regulatory restrictions, or for other reasons, each of which may negatively affect the Fund’s correlation with Underlying Stock. The Fund may also be subject to large movements of assets into and out of the Fund, potentially resulting in the Fund being under- or overexposed to Underlying Stock. Additionally, the Fund’s underlying investments and/or reference assets may trade on markets that may not be open on the same day as the Fund, which may cause a difference between the changes in the daily performance of the Fund and changes in the performance of Underlying Stock. Any of these factors could decrease correlation between the performance of the Fund and Underlying Stock and may hinder the Fund’s ability to meet its daily investment objective on or around that day.

| 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 Stock 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 Underlying Stock, 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 Underlying Stock declines more than 50%. Leverage will also have the effect of magnifying any differences in the Fund performance’s correlation with the Underlying Stock.
Due to the limited availability of necessary investments or financial instruments, the Fund could, among other things, as a defensive measure, limit or suspend creations or redemptions of Creation Units until the adviser determines that the requisite exposure to the Underlying Stock is obtainable. During the period that creation or redemptions are affected, the Fund’s shares could trade at a significant premium or discount to their net asset value, or the bid-ask spread of the Fund’s shares could widen significantly. In the case of a period during which creations are suspended, the Fund could experience significant redemptions, which may cause the Fund to sell portfolio securities at unfavorable prices and increased transaction and other costs and make greater taxable distributions to shareholders of the Fund.

| Risk [Text Block] | Derivatives Risk: The use of derivative instruments involves risks different from, or possibly greater than, the risks associated with investing directly in securities and other traditional investments. These risks include (i) the risk that the counterparty to a derivative transaction may not fulfill its contractual obligations; (ii) risk of mispricing or improper valuation; and (iii) the risk that changes in the value of the derivative may not correlate perfectly with the underlying asset, rate or index. Derivative prices are highly volatile and may fluctuate substantially during a short period of time. Such prices are influenced by numerous factors that affect the markets, including, but not limited to: changing supply and demand relationships; government programs and policies; national and international political and economic events, changes in interest rates, inflation and deflation and changes in supply and demand relationships. Trading derivative instruments involves risks different from, or possibly greater than, the risks associated with investing directly in securities.

| Risk [Text Block] | Exchange Traded Fund Structure Risk: The Fund is structured as an exchange traded fund and as a result is subject to special risks, including:
The Fund will be subject to regulatory constraints relating to the 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 leverage performance for the Fund.

| 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] | Market and Geopolitical Risk: The increasing interconnectivity between global economies and financial markets increases the likelihood that events or conditions in one region or financial market may adversely impact issuers in a different country, region or financial market. Securities in the Fund’s portfolio may underperform due to inflation (or expectations for inflation), interest rates, global demand for particular products or resources, natural disasters, pandemics, epidemics, terrorism, regulatory events and governmental or quasi-governmental actions. The occurrence of global events similar to those in recent years, such as terrorist attacks around the world, natural disasters, social and political discord or debt crises and downgrades, among others, may result in market volatility and may have long term effects on both the U.S. and global financial markets. It is difficult to predict when similar events affecting the U.S. or global financial markets may occur, the effects that such events may have and the duration of those effects.

| Prospectus [Line Items] | ||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||
| Risk [Text Block] | Options Contracts Risk: The use of options contracts involves investment strategies and risks different from those associated with ordinary portfolio securities transactions. The prices of options are volatile and are influenced by, among other things, actual and anticipated changes in the value of the underlying instrument, including the anticipated volatility, which are affected by fiscal and monetary policies and by national and international political, changes in the actual or implied volatility or the reference asset, the time remaining until the expiration of the option contract and economic events. For the Fund, in particular, the value of the options contracts in which it invests is substantially influenced by the value of the Underlying Stock. The Fund may experience substantial downside from specific option positions and certain option positions held by the Fund may expire worthless. As an option approaches its expiration date, its value typically increasingly moves with the value of the underlying instrument. However, prior to such a date, the value of an option generally does not increase or decrease at the same rate at the underlying instrument. There may at times be an imperfect correlation between the movement in values of 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. Furthermore, when the Fund seeks to trade out of positions, especially near expiration, there is an added risk that the Fund may be required to allocate resources unexpectedly to fulfill these obligations. This potential exposure to physical settlement can significantly impact the Fund’s liquidity and market exposure, particularly in volatile market conditions. If the Fund sells non-cash settled options contracts, it would be obligated to receive shares of the Underlying Stock when the option is exercised. Consequently, there is a risk that the Fund may have to physically acquire the Underlying Stock shares at the strike price, which could result in the Fund holding the Underlying Stock, and an asset that has declined in value. The level of exposure obtained through option contracts should at most be equal to the Fund’s Daily Leverage Factor times the Fund’s net asset value.

| 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 Stock that is significantly greater or less than its stated multiple. As a result, the Fund may be more exposed to leverage risk than if it had been properly rebalanced and may not achieve its investment objective.

| Risk [Text Block] | Trading Halt Risk: Although the Underlying Stock’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 Stock’s shares is expected, in turn, to result in a halt in the trading in the Fund’s shares. Trading in the Underlying Stock’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 Underling Stock’s and/or Fund’s shares inadvisable. In addition, trading in Underlying Stock’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] | Tracking Error Risk: Tracking error is the divergence of the Fund’s performance from that of its investment objective which aims to replicate 2 times the daily percentage change of the Underlying Stock. The performance of the Fund may diverge from that of its investment objective 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 Stock 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. The Fund may be required to deviate from its investment objective as a result of market restrictions or other legal reasons, including regulatory limits or other restrictions on securities that may be purchased by the Adviser and its affiliates.

| Risk [Text Block] | Tax Risk: 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, particularly because the Fund’s investment objective focuses on the performance of the stock of a single issuer. 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] | Bitcoin Risk: The performance of the Underlying Stock, and consequently the Fund’s performance, is subject to risks associated with bitcoin. Investing in bitcoin exposes 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. Bitcoin is not presently widely accepted as a medium of exchange, which may be due to a number of common impediments and/or disadvantages to adopting the Bitcoin Network as a payment network, including the slowness of transaction processing and finality, variability of transaction fees, and volatility of the price of bitcoin. Additionally, risks associated with the sale of newly mined bitcoin, bitcoin trading platforms, competition from alternative digital assets, mining operations, network modifications, and intellectual property claims pose further challenges to bitcoin-linked investments. The value of bitcoin has been, may continue to be, substantially dependent on speculation, such that trading and investing in these assets generally may not be based on fundamental analysis. The Fund’s daily returns may be affected by many factors but will depend on the performance and volatility of the Underlying Stock.

| Risk [Text Block] | Bitcoin Halving. While bitcoin prices have historically increased around halving events (a process designed to control the overall supply and reduce the risk of inflation in bitcoin, which uses a proof-of-work consensus algorithm and results in the mining reward being cut in half) there is no guarantee that the price change will be favorable or would compensate for the reduction in mining rewards. If a corresponding and proportionate increase in the price of Bitcoin does not follow future halving events, the revenue RIOT earns from its bitcoin mining operations would see a decrease, which could have a material adverse effect on RIOT’s results of operations and financial condition.

| Prospectus [Line Items] | ||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||
| Risk [Text Block] | Hash Rate and Difficulty. As demand for bitcoin has increased, the global network hash rate (i.e., the aggregate amount of computing power devoted to supporting the bitcoin blockchain at a given time) has increased rapidly, and as greater adoption of bitcoin occurs, it is expected that demand for new bitcoin will likewise increase as more mining companies are drawn into the industry by this increased demand. Further, as a greater number of increasingly powerful miners have been deployed, the network difficulty for bitcoin has consequently also increased. A high difficulty means that more computing power will be required in order to solve a block and earn a new bitcoin reward, which, in turn, makes the bitcoin network more secure by limiting the possibility of one miner or mining pool gaining control of the network. Therefore, as new and existing miners deploy additional hash rate, the global network hash rate will continue to increase, meaning a miner’s share of the global network hash rate (and therefore its chance of earning bitcoin rewards) will decline if it fails to deploy additional hash rate at pace with the industry. If an effort to grow the hash rate, results in the inability to complete planned expansions on schedule and within anticipated cost estimates, deployment of newly purchased miners may be delayed, which could affect its competitiveness and results of operation, which could have a material adverse effect on the Underlying Stock’s financial condition and market price for its securities.

| Risk [Text Block] | Blockchain Risk: Blockchain companies may be adversely impacted by government regulations or economic conditions. Blockchain technology is new and its uses are in many cases untested or unclear. These companies may also have significant exposure to fluctuations in the spot prices of digital assets, particularly to the extent that demand for a company’s hardware or services may increase as the spot price of digital assets increase. Blockchain companies typically face intense competition and potentially rapid product obsolescence. In addition, many Blockchain companies store sensitive consumer information and could be the target of cybersecurity attacks and other types of theft, which could have a negative impact on these companies. Access to a given blockchain may require a specific cryptographic key (in effect a string of characters granting unique access to initiate transactions related to specific digital assets) or set of keys, the theft, loss, or destruction of which, either by accident or as a result of the efforts of a third party, could irrevocably impair a claim to the digital assets stored on that blockchain. Many Blockchain companies currently operate under less regulatory scrutiny than traditional financial services companies and banks, but there is significant risk that regulatory oversight could increase in the future. Higher levels of regulation could increase costs and adversely impact the current business models of some Blockchain companies. For example, restrictions imposed by foreign governments, including China, on the use and mining of digital assets, may adversely impact Blockchain Companies and in turn the Fund. These companies could be negatively impacted by disruptions in service caused by hardware or software failure, or by interruptions or delays in service by third-party data center hosting facilities and maintenance providers. Blockchain companies involved in digital assets may face slow adoption rates and be subject to higher levels of regulatory scrutiny in the future, which could severely impact the viability of these companies. Blockchain companies, especially smaller companies, tend to be more volatile than companies that do not rely heavily on technology. The customers and/or suppliers of Blockchain companies may be concentrated in a particular country, region or industry. Any adverse event affecting one of these countries, regions or industries could have a negative impact on Blockchain companies.

| Risk [Text Block] | Underlying Stock Risk: The performance of the Underlying Stock, and consequently the Fund’s performance, is subject to the risks of the software and information technology industry. The Underlying Stock is subject to many risks that can negatively impact its revenue and viability including, but are not limited to price volatility risk, management risk, inflation risk, global economic risk, growth risk, supply and demand risk, operations risk, regulatory risk, environmental risk, terrorism risk and the risk of natural disasters. The Underlying Stock performance may be affected by global markets and demand for its products and services, its ability to develop new products and services, inventory levels, supply chain issues, the performance of third-party software developers, system and network failures, privacy and cybersecurity breaches and changes in international and government regulations. Information technology companies are heavily dependent on patent and intellectual property rights, the loss or impairment of which may adversely affect profitability. Additionally, companies in the information technology industry may face dramatic and often unpredictable changes in growth rates and competition for the services of qualified personnel. The Fund’s daily returns may be affected by many factors but will depend on the performance and volatility of the Underlying Stock.

| Prospectus [Line Items] | ||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||
| Risk [Text Block] | Effects of Compounding and Market Volatility Risk: The Fund aims to replicate the daily inverse returns of the Underlying Stock 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 Underlying Stock’s performance, before fees and expenses. Compounding affects all investments but has a more significant impact on funds that aims to replicate inverse daily returns. For a Fund aiming to replicate the inverse performance of an Underlying Stock, if adverse daily performance of the Underlying Stock 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 the favorable daily performance of the Underlying Stock 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 pronounced as the Underlying Stock 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 Stock during the shareholder’s holding period of an investment in the Fund.
The chart below provides examples of how Underlying Stock volatility could affect the Fund’s performance. Fund performance for periods greater than one single day can be estimated given any set of assumptions for the following factors: a) Underlying Stock volatility; b) Underlying Stock’s performance; c) period of time; d) financing rates associated with leveraged exposure; e) other Fund expenses; and f) the Underlying Stock’s dividends. The chart below illustrates the impact of two principal factors – Underlying Stock volatility and performance – on Fund performance. The chart shows estimated Fund returns for a number of combinations of Underlying Stock volatility and performance over a one-year period. Performance shown in the chart assumes that (i) there were no Fund expenses; and (ii) borrowing rates (needed to obtain a leveraged long exposure) of 0%. If Fund expenses and/or actual borrowing/lending rates were reflected, the estimated returns would be lower than those shown. Particularly during periods of higher Underlying Stock volatility, compounding will cause results for periods longer than a trading day to vary from the performance of the Underlying Stock.
As shown in the chart below, the Fund would be expected to lose 17.0% if the Underlying Stock provided no return over a one-year period during which the Underlying Stock experienced annualized volatility of 25%. At higher ranges of volatility, there is a chance of a significant loss of value in the Fund, even if the Underlying Stock return is flat.
For instance, if the Underlying Stock’s annualized volatility is 100%, the Inverse Fund would be expected to lose 95.3% of its value, even if the cumulative Underlying Stock’s return for the year was 0%. Areas shaded red (or dark gray) represent those scenarios where the Inverse Fund can be expected to return less than -200% of the performance of the Underlying Stock and those shaded green (or light gray) represent those scenarios where the Fund can be expected to return more than -200% of the performance of the Underlying Stock. The Inverse Fund’s actual returns may be significantly better or worse than the returns shown below as a result of any of the factors discussed above or in “Tracking Error Risk” below.
The Underlying Stock’s annualized historical volatility rate for the five-year period ended August 31, 2025, was 97.1%. During the five-year period observed the Underlying Stock’s highest volatility rate over a 12-month period was 106.4% and volatility for a shorter period of time may have been substantially higher. The Underlying Stock’s annualized performance for the five-year period ended August 31, 2025, was 86.5%. Historical volatility and performance are not indications of what the Underlying Stock volatility and performance will be in the future. The volatility of instruments that reflect the value of the Underlying Stock, such as swaps, may differ from the volatility of the Underlying Stock.

| Risk [Text Block] | Correlation Risk: A number of factors may affect the Fund’s ability to achieve a high degree of correlation with Underlying Stock, and there is no guarantee that the Fund will achieve a high degree of correlation. Failure to achieve a high degree of correlation may prevent the Fund from achieving its investment objective, and the percentage change of the Fund’s NAV each day may differ, perhaps significantly in amount, and possibly even direction, from -100% of the percentage change of Underlying Stock on such day.
In order to achieve a high degree of correlation with Underlying Stock, the Fund seeks to rebalance its portfolio daily to keep exposure consistent with its investment objective. Being materially under- or overexposed to Underlying Stock may prevent the Fund from achieving a high degree of correlation with Underlying Stock and may expose the Fund to greater leverage risk. Market disruptions or closure, regulatory restrictions, market volatility, illiquidity in the markets for the financial instruments in which the Fund invests, and other factors will adversely affect the Fund’s ability to adjust exposure to requisite levels. The target amount of portfolio exposure is impacted dynamically by Underlying Stock’s movements, including intraday movements. Because of this, it is unlikely that the Fund will have perfect -200% exposure during the day or at the end of each day and the likelihood of being materially under- or overexposed is higher on days when Underlying Stock is volatile, particularly when Underlying Stock is volatile at or near the close of the trading day.
A number of other factors may also adversely affect the Fund’s correlation with Underlying Stock, including fees, expenses, transaction costs, financing costs associated with the use of derivatives, income items, valuation methodology, accounting standards and disruptions or illiquidity in the markets for the securities or financial instruments in which the Fund invests. The Fund may take or refrain from taking positions in order to improve tax efficiency, comply with regulatory restrictions, or for other reasons, each of which may negatively affect the Fund’s correlation with Underlying Stock. The Fund may also be subject to large movements of assets into and out of the Fund, potentially resulting in the Fund being under- or overexposed to Underlying Stock. Additionally, the Fund’s underlying investments and/or reference assets may trade on markets that may not be open on the same day as the Fund, which may cause a difference between the changes in the daily performance of the Fund and changes in the performance of Underlying Stock. Any of these factors could decrease correlation between the performance of the Fund and Underlying Stock and may hinder the Fund’s ability to meet its daily investment objective on or around that day.

| Risk [Text Block] | Derivatives Risk: The use of derivative instruments involves risks different from, or possibly greater than, the risks associated with investing directly in securities and other traditional investments. These risks include (i) the risk that the counterparty to a derivative transaction may not fulfill its contractual obligations; (ii) risk of mispricing or improper valuation; and (iii) the risk that changes in the value of the derivative may not correlate perfectly with the underlying asset, rate or index. Derivative prices are highly volatile and may fluctuate substantially during a short period of time. Such prices are influenced by numerous factors that affect the markets, including, but not limited to: changing supply and demand relationships; government programs and policies; national and international political and economic events, changes in interest rates, inflation and deflation and changes in supply and demand relationships. Trading derivative instruments involves risks different from, or possibly greater than, the risks associated with investing directly in securities.

| Risk [Text Block] | Exchange Traded Fund Structure Risk: The Fund is structured as an exchange traded fund and as a result is subject to special risks, including:
The Fund will be subject to regulatory constraints relating to the 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 inverse performance for the Fund.

| 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] | Market and Geopolitical Risk: The increasing interconnectivity between global economies and financial markets increases the likelihood that events or conditions in one region or financial market may adversely impact issuers in a different country, region or financial market. Securities in the Fund’s portfolio may underperform due to inflation (or expectations for inflation), interest rates, global demand for particular products or resources, natural disasters, pandemics, epidemics, terrorism, regulatory events and governmental or quasi-governmental actions. The occurrence of global events similar to those in recent years, such as terrorist attacks around the world, natural disasters, social and political discord or debt crises and downgrades, among others, may result in market volatility and may have long term effects on both the U.S. and global financial markets. It is difficult to predict when similar events affecting the U.S. or global financial markets may occur, the effects that such events may have and the duration of those effects.

| Prospectus [Line Items] | ||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||
| Risk [Text Block] | Options Contracts Risk: The use of options contracts involves investment strategies and risks different from those associated with ordinary portfolio securities transactions. The prices of options are volatile and are influenced by, among other things, actual and anticipated changes in the value of the underlying instrument, including the anticipated volatility, which are affected by fiscal and monetary policies and by national and international political, changes in the actual or implied volatility or the reference asset, the time remaining until the expiration of the option contract and economic events. For the Fund, in particular, the value of the options contracts in which it invests is substantially influenced by the value of the Underlying Stock. The Fund may experience substantial downside from specific option positions and certain option positions held by the Fund may expire worthless. As an option approaches its expiration date, its value typically increasingly moves with the value of the underlying instrument. However, prior to such a date, the value of an option generally does not increase or decrease at the same rate at the underlying instrument. There may at times be an imperfect correlation between the movement in values of 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. Furthermore, when the Fund seeks to trade out of positions, especially near expiration, there is an added risk that the Fund may be required to allocate resources unexpectedly to fulfill these obligations. This potential exposure to physical settlement can significantly impact the Fund’s liquidity and market exposure, particularly in volatile market conditions. If the Fund sells non-cash settled options contracts, it would be obligated to receive shares of the Underlying Stock when the option is exercised. Consequently, there is a risk that the Fund may have to physically acquire the Underlying Stock shares at the strike price, which could result in the Fund holding the Underlying Stock, and an asset that has declined in value. The level of exposure obtained through option contracts should at most be equal to the Fund’s Daily Leverage Factor times the Fund’s net asset value.

| 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 Stock that is significantly greater or less than its stated multiple. As a result, the Fund may be more exposed to leverage risk than if it had been properly rebalanced and may not achieve its investment objective.

| Risk [Text Block] | Trading Halt Risk: Although the Underlying Stock’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 Stock’s shares is expected, in turn, to result in a halt in the trading in the Fund’s shares. Trading in the Underlying Stock’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 Underling Stock’s and/or Fund’s shares inadvisable. In addition, trading in Underlying Stock’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] | Tracking Error Risk: Tracking error is the divergence of the Fund’s performance from that of its investment objective which aims to replicate the inverse daily percentage change of the Underlying Stock. The performance of the Fund may diverge from that of its investment objective 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 Stock 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 have difficulty achieving its daily leveraged investment objective due to its difficulty to adjust its exposure to the Underlying Security, resulting in over or under-exposition. The Fund may be required to deviate from its investment objectives as a result of market restrictions or other legal reasons, including regulatory limits or other restrictions on securities that may be purchased by the Adviser and its affiliates.

| Risk [Text Block] | Tax Risk: 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, particularly because the Fund’s investment objective focuses on the performance of the stock of a single issuer. 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] | Bitcoin Risk: The performance of the Underlying Stock, and consequently the Fund’s performance, is subject to risks associated with bitcoin. Investing in bitcoin exposes 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. Bitcoin is not presently widely accepted as a medium of exchange, which may be due to a number of common impediments and/or disadvantages to adopting the Bitcoin Network as a payment network, including the slowness of transaction processing and finality, variability of transaction fees, and volatility of the price of bitcoin. Additionally, risks associated with the sale of newly mined bitcoin, bitcoin trading platforms, competition from alternative digital assets, mining operations, network modifications, and intellectual property claims pose further challenges to bitcoin-linked investments. The value of bitcoin has been, may continue to be, substantially dependent on speculation, such that trading and investing in these assets generally may not be based on fundamental analysis. The Fund’s daily returns may be affected by many factors but will depend on the performance and volatility of the Underlying Stock.

| Risk [Text Block] | Short Sale Exposure Risk: The Fund will seek inverse or “short” exposure through financial instruments, which would cause the Fund to be exposed to certain risks associated with selling short. These risks include, under certain market conditions, an increase in the volatility and decrease in the liquidity of the instruments underlying the short position, which may lower the Fund’s return, result in a loss, have the effect of limiting the Fund’s ability to obtain inverse exposure through financial instruments, or require the Fund to seek inverse exposure through alternative investment strategies that may be less desirable or more costly to implement. To the extent that, at any particular point in time, the instruments underlying the short position may be thinly traded or have a limited market, including due to regulatory action, the Fund may be unable to meet its investment objective due to a lack of available securities or counterparties. During such periods, the Fund’s ability to issue additional Creation Units may be adversely affected. Obtaining inverse exposure through these instruments may be considered an aggressive investment technique. Any income, dividends or payments by any assets underlying the Fund’s short positions, if any, would negatively impact the Fund. The Fund could theoretically lose an amount greater than its net assets in the event the Underlying Stock increases more than 50%.
Due to the limited availability of necessary investments or financial instruments, the Fund could, among other things, as a defensive measure, limit or suspend creations or redemptions of Creation Units until the adviser determines that the requisite exposure to the underlying Stock is obtainable. During the period that creation or redemptions are affected, the Fund’s shares could trade at a significant premium or discount to their net asset value, or the bid-ask spread of the Fund’s shares could widen significantly. In the case of a period during which creations are suspended, the Fund could experience significant redemptions, which may cause the Fund to sell portfolio securities at unfavorable prices and increased transaction and other costs and make greater taxable distributions to shareholders of the Fund.

| Risk [Text Block] | Underlying Stock Risk: The performance of the Underlying Stock, and consequently the Fund’s performance, is subject to the risks of the semiconductor sector. The Underlying Stock is subject to many risks that can negatively impact its revenue and viability including, but are not limited to price volatility risk, management risk, inflation risk, global economic risk, growth risk, supply and demand risk, operations risk, regulatory risk, environmental risk, terrorism risk and the risk of natural disasters. The Underlying Stock performance may be affected by the company’s significant customer losses, its inability to develop and implement new technologies, its reliance on third-party distributors and platforms, cybersecurity attacks, its inability to protect its intellectual property rights and global laws and regulations affecting privacy, data protection and technology protections. The semiconductor industry may also be affected by risks that affect the broader technology sector, including: government regulation; dramatic and often unpredictable changes in growth rates and competition for qualified personnel; and a small number of companies representing a large portion of the technology sector as a whole. The Fund’s daily returns may be affected by many factors but will depend on the performance and volatility of the Underlying Stock.

| Prospectus [Line Items] | ||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||
| Risk [Text Block] | Effects of Compounding and Market Volatility Risk: The Fund’s aims to replicate the leveraged daily returns of the Underlying Stock 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 the Underlying Stock’s performance, before fees and expenses. Compounding affects all investments but has a more significant impact on funds that aims to replicate leverage daily returns. For a Fund aiming to replicate 2 times the daily performance of an Underlying Stock, if adverse daily performance of the Underlying Stock 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 the favorable daily performance of the Underlying Stock 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 pronounced as the Underlying Stock 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 Stock during the shareholder’s holding period of an investment in the Fund.
The chart below provides examples of how Underlying Stock volatility could affect the Fund’s performance. Fund performance for periods greater than one single day can be estimated given any set of assumptions for the following factors: a) Underlying Stock volatility; b) Underlying Stock’s performance; c) period of time; d) financing rates associated with leveraged exposure; e) other Fund expenses; and f) the Underlying Stock’s dividends. The chart below illustrates the impact of two principal factors – Underlying Stock volatility and performance – on Fund performance.
The chart shows estimated Fund returns for a number of combinations of Underlying Stock volatility and performance over a one-year period. Performance shown in the chart assumes that (i) there were no Fund expenses; and (ii) borrowing rates (needed to obtain a leveraged long exposure) of 0%. If Fund expenses and/or actual borrowing/lending rates were reflected, the estimated returns would be lower than those shown. Particularly during periods of higher Underlying Stock volatility, compounding will cause results for periods longer than a trading day to vary from the performance of the Underlying Stock.
As shown in the chart below, the Fund would be expected to lose 6.0% if the Underlying Stock provided no return over a one-year period during which the Underlying Stock experienced annualized volatility of 25%. At higher ranges of volatility, there is a chance of a significant loss of value in the Fund, even if the Underlying Stock return is flat.
For instance, if the Underlying Stock annualized volatility is 100%, the Fund would be expected to lose 63.3% of its value, even if the cumulative Underlying Stock return for the year was 0%. Areas shaded red (or dark gray) represent those scenarios where the Fund can be expected to return less than 200% of the performance of the Underlying Stock and those shaded green (or light gray) represent those scenarios where the Fund can be expected to return more than 200% of the performance of the Underlying Stock. The Fund’s actual returns may be significantly better or worse than the returns shown below as a result of any of the factors discussed above or in “Tracking Error Risk” below.
The Underlying Stock’s annualized historical volatility rate for the five-year period ended August 31, 2025, was 58.4%. During the period observed the Underlying Stock’s highest volatility rate over a 12-month period was 62.8% and volatility for a shorter period of time may have been substantially higher. The Underlying Stock’s annualized performance for the five-year period ended August 31, 2025, was 10.4%. Historical volatility and performance are not indications of what the Underlying Stock volatility and performance will be in the future. The volatility of instruments that reflect the value of the Underlying Stock, such as swaps, may differ from the volatility of the Underlying Stock.

| Risk [Text Block] | Correlation Risk: A number of factors may affect the Fund’s ability to achieve a high degree of correlation with Underlying Stock, and there is no guarantee that the Fund will achieve a high degree of correlation. Failure to achieve a high degree of correlation may prevent the Fund from achieving its investment objective, and the percentage change of the Fund’s NAV each day may differ, perhaps significantly in amount, and possibly even direction, from 200% of the percentage change of Underlying Stock on such day.
In order to achieve a high degree of correlation with Underlying Stock, the Fund seeks to rebalance its portfolio daily to keep exposure consistent with its investment objective. Being materially under- or overexposed to Underlying Stock may prevent the Fund from achieving a high degree of correlation with Underlying Stock and may expose the Fund to greater leverage risk. Market disruptions or closure, regulatory restrictions, market volatility, illiquidity in the markets for the financial instruments in which the Fund invests, and other factors will adversely affect the Fund’s ability to adjust exposure to requisite levels. The target amount of portfolio exposure is impacted dynamically by Underlying Stock’s movements, including intraday movements. Because of this, it is unlikely that the Fund will have perfect 200% exposure during the day or at the end of each day and the likelihood of being materially under- or overexposed is higher on days when Underlying Stock is volatile, particularly when Underlying Stock is volatile at or near the close of the trading day.
A number of other factors may also adversely affect the Fund’s correlation with Underlying Stock, including fees, expenses, transaction costs, financing costs associated with the use of derivatives, income items, valuation methodology, accounting standards and disruptions or illiquidity in the markets for the securities or financial instruments in which the Fund invests. The Fund may take or refrain from taking positions in order to improve tax efficiency, comply with regulatory restrictions, or for other reasons, each of which may negatively affect the Fund’s correlation with Underlying Stock. The Fund may also be subject to large movements of assets into and out of the Fund, potentially resulting in the Fund being under- or overexposed to Underlying Stock. Additionally, the Fund’s underlying investments and/or reference assets may trade on markets that may not be open on the same day as the Fund, which may cause a difference between the changes in the daily performance of the Fund and changes in the performance of Underlying Stock. Any of these factors could decrease correlation between the performance of the Fund and Underlying Stock and may hinder the Fund’s ability to meet its daily investment objective on or around that day.

| 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 Stock 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 Underlying Stock, 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 Underlying Stock declines more than 50%. Leverage will also have the effect of magnifying any differences in the Fund performance’s correlation with the Underlying Stock.
Due to the limited availability of necessary investments or financial instruments, the Fund could, among other things, as a defensive measure, limit or suspend creations or redemptions of Creation Units until the adviser determines that the requisite exposure to the Underlying Stock is obtainable. During the period that creation or redemptions are affected, the Fund’s shares could trade at a significant premium or discount to their net asset value, or the bid-ask spread of the Fund’s shares could widen significantly. In the case of a period during which creations are suspended, the Fund could experience significant redemptions, which may cause the Fund to sell portfolio securities at unfavorable prices and increased transaction and other costs and make greater taxable distributions to shareholders of the Fund.

| Risk [Text Block] | Derivatives Risk: The use of derivative instruments involves risks different from, or possibly greater than, the risks associated with investing directly in securities and other traditional investments. These risks include (i) the risk that the counterparty to a derivative transaction may not fulfill its contractual obligations; (ii) risk of mispricing or improper valuation; and (iii) the risk that changes in the value of the derivative may not correlate perfectly with the underlying asset, rate or index. Derivative prices are highly volatile and may fluctuate substantially during a short period of time. Such prices are influenced by numerous factors that affect the markets, including, but not limited to: changing supply and demand relationships; government programs and policies; national and international political and economic events, changes in interest rates, inflation and deflation and changes in supply and demand relationships. Trading derivative instruments involves risks different from, or possibly greater than, the risks associated with investing directly in securities.

The Fund will be subject to regulatory constraints relating to the level of value at risk that the Fund may incur through its derivative portfolio.

| 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] | Market and Geopolitical Risk: The increasing interconnectivity between global economies and financial markets increases the likelihood that events or conditions in one region or financial market may adversely impact issuers in a different country, region or financial market. Securities in the Fund’s portfolio may underperform due to inflation (or expectations for inflation), interest rates, global demand for particular products or resources, natural disasters, pandemics, epidemics, terrorism, regulatory events and governmental or quasi-governmental actions. The occurrence of global events similar to those in recent years, such as terrorist attacks around the world, natural disasters, social and political discord or debt crises and downgrades, among others, may result in market volatility and may have long term effects on both the U.S. and global financial markets. It is difficult to predict when similar events affecting the U.S. or global financial markets may occur, the effects that such events may have and the duration of those effects.

| Prospectus [Line Items] | ||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||
| Risk [Text Block] | Options Contracts Risk: The use of options contracts involves investment strategies and risks different from those associated with ordinary portfolio securities transactions. The prices of options are volatile and are influenced by, among other things, actual and anticipated changes in the value of the underlying instrument, including the anticipated volatility, which are affected by fiscal and monetary policies and by national and international political, changes in the actual or implied volatility or the reference asset, the time remaining until the expiration of the option contract and economic events. For the Fund, in particular, the value of the options contracts in which it invests is substantially influenced by the value of the Underlying Stock. The Fund may experience substantial downside from specific option positions and certain option positions held by the Fund may expire worthless. As an option approaches its expiration date, its value typically increasingly moves with the value of the underlying instrument. However, prior to such a date, the value of an option generally does not increase or decrease at the same rate at the underlying instrument. There may at times be an imperfect correlation between the movement in values of 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. Furthermore, when the Fund seeks to trade out of positions, especially near expiration, there is an added risk that the Fund may be required to allocate resources unexpectedly to fulfill these obligations. This potential exposure to physical settlement can significantly impact the Fund’s liquidity and market exposure, particularly in volatile market conditions. If the Fund sells non-cash settled options contracts, it would be obligated to receive shares of the Underlying Stock when the option is exercised. Consequently, there is a risk that the Fund may have to physically acquire the Underlying Stock shares at the strike price, which could result in the Fund holding the Underlying Stock, and an asset that has declined in value. The level of exposure obtained through option contracts should at most be equal to the Fund’s Daily Leverage Factor times the Fund’s net asset value.

| 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 Stock that is significantly greater or less than its stated multiple. As a result, the Fund may be more exposed to leverage risk than if it had been properly rebalanced and may not achieve its investment objective.

| Risk [Text Block] | Trading Halt Risk: Although the Underlying Stock’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 Stock’s shares is expected, in turn, to result in a halt in the trading in the Fund’s shares. Trading in the Underlying Stock’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 Underling Stock’s and/or Fund’s shares inadvisable. In addition, trading in Underlying Stock’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] | Tracking Error Risk: Tracking error is the divergence of the Fund’s performance from that of its investment objective which aims to replicate 2 times the daily percentage change of the Underlying Stock. The performance of the Fund may diverge from that of its investment objective 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 Stock 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. The Fund may be required to deviate from its investment objective as a result of market restrictions or other legal reasons, including regulatory limits or other restrictions on securities that may be purchased by the Adviser and its affiliates.

| Risk [Text Block] | Tax Risk: 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, particularly because the Fund’s investment objective focuses on the performance of the stock of a single issuer. 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] | Underlying Stock Risk: The performance of the Underlying Stock, and consequently the Fund’s performance, is subject to the risks of the business services industry. Any general economic, business or industry conditions that cause customers or potential customers to reduce or delay their purchases of business services or other products could have a material adverse effect on our company, its prospects and financial performance. Worldwide economic conditions could have an effect on the demand for our company’s services and products and could result in declining revenue and earnings. General economic declines or a softening of the economy make it more likely that our company may experience difficulties collecting accounts receivable, sales and demand for our company’s products may decrease, and our company’s operating results may be adversely affected. The Fund’s daily returns may be affected by many factors but will depend on the performance and volatility of the Underlying Stock.

| Prospectus [Line Items] | ||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||
| Risk [Text Block] | Effects of Compounding and Market Volatility Risk: The Fund aims to replicate the daily leverage returns of the Underlying Stock 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 Underlying Stock’s performance, before fees and expenses. Compounding affects all investments but has a more significant impact on funds that aims to replicate leverage daily returns. For a Fund aiming to replicate 2 times the daily performance of an Underlying Stock, if adverse daily performance of the Underlying Stock 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 the favorable daily performance of the Underlying Stock 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 pronounced as the Underlying Stock 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 Stock during the shareholder’s holding period of an investment in the Fund.
The chart below provides examples of how Underlying Stock volatility could affect the Fund’s performance. Fund performance for periods greater than one single day can be estimated given any set of assumptions for the following factors: a) Underlying Stock volatility; b) Underlying Stock’s performance; c) period of time; d) financing rates associated with leveraged exposure; e) other Fund expenses; and f) the Underlying Stock’s dividends. The chart below illustrates the impact of two principal factors – Underlying Stock volatility and performance – on Fund performance.
The chart shows estimated Fund returns for a number of combinations of Underlying Stock volatility and performance over a one-year period. Performance shown in the chart assumes that (i) there were no Fund expenses; and (ii) borrowing rates (needed to obtain a leveraged long exposure) of 0%. If Fund expenses and/or actual borrowing/lending rates were reflected, the estimated returns would be lower than those shown. Particularly during periods of higher Underlying Stock volatility, compounding will cause results for periods longer than a trading day to vary from the performance of the Underlying Stock.
As shown in the chart below, the Fund would be expected to lose 6.0% if the Underlying Stock provided no return over a one-year period during which the Underlying Stock experienced annualized volatility of 25%. At higher ranges of volatility, there is a chance of a significant loss of value in the Fund, even if the Underlying Stock return is flat.
For instance, if the Underlying Stock’s annualized volatility is 100%, the Fund would be expected to lose 63.3% of its value, even if the cumulative Underlying Stock’s return for the year was 0%. Areas shaded red (or dark gray) represent those scenarios where the Fund can be expected to return less than 200% of the performance of the Underlying Stock and those shaded green (or light gray) represent those scenarios where the Fund can be expected to return more than 200% of the performance of the Underlying Stock. The Fund’s actual returns may be significantly better or worse than the returns shown below as a result of any of the factors discussed above or in “Tracking Error Risk” below.
The Underlying Stock’s annualized historical volatility rate for the five-year period ended August 31, 2025, was 73.9%. During the five-year period observed the Underlying Stock’s highest volatility rate over a 12-month period was 106.8% and volatility for a shorter period of time may have been substantially higher. The Underlying Stock’s annualized performance for the five-year period ended August 31, 2025 was 5.7%. Historical volatility and performance are not indications of what the Underlying Stock volatility and performance will be in the future. The volatility of instruments that reflect the value of the Underlying Stock, such as swaps, may differ from the volatility of the Underlying Stock.

| Risk [Text Block] | Correlation Risk: A number of factors may affect the Fund’s ability to achieve a high degree of correlation with Underlying Stock, and there is no guarantee that the Fund will achieve a high degree of correlation. Failure to achieve a high degree of correlation may prevent the Fund from achieving its investment objective, and the percentage change of the Fund’s NAV each day may differ, perhaps significantly in amount, and possibly even direction, from 200% of the percentage change of Underlying Stock on such day.
In order to achieve a high degree of correlation with Underlying Stock, the Fund seeks to rebalance its portfolio daily to keep exposure consistent with its investment objective. Being materially under- or overexposed to Underlying Stock may prevent the Fund from achieving a high degree of correlation with Underlying Stock and may expose the Fund to greater leverage risk. Market disruptions or closure, regulatory restrictions, market volatility, illiquidity in the markets for the financial instruments in which the Fund invests, and other factors will adversely affect the Fund’s ability to adjust exposure to requisite levels. The target amount of portfolio exposure is impacted dynamically by Underlying Stock’s movements, including intraday movements. Because of this, it is unlikely that the Fund will have perfect 200% exposure during the day or at the end of each day and the likelihood of being materially under- or overexposed is higher on days when Underlying Stock is volatile, particularly when Underlying Stock is volatile at or near the close of the trading day.
A number of other factors may also adversely affect the Fund’s correlation with Underlying Stock, including fees, expenses, transaction costs, financing costs associated with the use of derivatives, income items, valuation methodology, accounting standards and disruptions or illiquidity in the markets for the securities or financial instruments in which the Fund invests. The Fund may take or refrain from taking positions in order to improve tax efficiency, comply with regulatory restrictions, or for other reasons, each of which may negatively affect the Fund’s correlation with Underlying Stock. The Fund may also be subject to large movements of assets into and out of the Fund, potentially resulting in the Fund being under- or overexposed to Underlying Stock. Additionally, the Fund’s underlying investments and/or reference assets may trade on markets that may not be open on the same day as the Fund, which may cause a difference between the changes in the daily performance of the Fund and changes in the performance of Underlying Stock. Any of these factors could decrease correlation between the performance of the Fund and Underlying Stock and may hinder the Fund’s ability to meet its daily investment objective on or around that day.

| 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 Stock 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 Underlying Stock, 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 Underlying Stock declines more than 50%. Leverage will also have the effect of magnifying any differences in the Fund performance’s correlation with the Underlying Stock.
Due to the limited availability of necessary investments or financial instruments, the Fund could, among other things, as a defensive measure, limit or suspend creations or redemptions of Creation Units until the adviser determines that the requisite exposure to the underlying Stock is obtainable. During the period that creation or redemptions are affected, the Fund’s shares could trade at a significant premium or discount to their net asset value, or the bid-ask spread of the Fund’s shares could widen significantly. In the case of a period during which creations are suspended, the Fund could experience significant redemptions, which may cause the Fund to sell portfolio securities at unfavorable prices and increased transaction and other costs and make greater taxable distributions to shareholders of the Fund.

| 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] | Market and Geopolitical Risk: The increasing interconnectivity between global economies and financial markets increases the likelihood that events or conditions in one region or financial market may adversely impact issuers in a different country, region or financial market. Securities in the Fund’s portfolio may underperform due to inflation (or expectations for inflation), interest rates, global demand for particular products or resources, natural disasters, pandemics, epidemics, terrorism, regulatory events and governmental or quasi-governmental actions. The occurrence of global events similar to those in recent years, such as terrorist attacks around the world, natural disasters, social and political discord or debt crises and downgrades, among others, may result in market volatility and may have long term effects on both the U.S. and global financial markets. It is difficult to predict when similar events affecting the U.S. or global financial markets may occur, the effects that such events may have and the duration of those effects.

| Prospectus [Line Items] | ||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||
| Risk [Text Block] | Options Contracts Risk: The use of options contracts involves investment strategies and risks different from those associated with ordinary portfolio securities transactions. The prices of options are volatile and are influenced by, among other things, actual and anticipated changes in the value of the underlying instrument, including the anticipated volatility, which are affected by fiscal and monetary policies and by national and international political, changes in the actual or implied volatility or the reference asset, the time remaining until the expiration of the option contract and economic events. For the Fund, in particular, the value of the options contracts in which it invests is substantially influenced by the value of the Underlying Stock. The Fund may experience substantial downside from specific option positions and certain option positions held by the Fund may expire worthless. As an option approaches its expiration date, its value typically increasingly moves with the value of the underlying instrument. However, prior to such a date, the value of an option generally does not increase or decrease at the same rate at the underlying instrument. There may at times be an imperfect correlation between the movement in values of 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. Furthermore, when the Fund seeks to trade out of positions, especially near expiration, there is an added risk that the Fund may be required to allocate resources unexpectedly to fulfill these obligations. This potential exposure to physical settlement can significantly impact the Fund’s liquidity and market exposure, particularly in volatile market conditions. If the Fund sells non-cash settled options contracts, it would be obligated to receive shares of the Underlying Stock when the option is exercised. Consequently, there is a risk that the Fund may have to physically acquire the Underlying Stock shares at the strike price, which could result in the Fund holding the Underlying Stock, and an asset that has declined in value. The level of exposure obtained through option contracts should at most be equal to the Fund’s Daily Leverage Factor times the Fund’s net asset value.

| 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 Stock that is significantly greater or less than its stated multiple. As a result, the Fund may be more exposed to leverage risk than if it had been properly rebalanced and may not achieve its investment objective.

| Risk [Text Block] | Trading Halt Risk: Although the Underlying Stock’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 Stock’s shares is expected, in turn, to result in a halt in the trading in the Fund’s shares. Trading in the Underlying Stock’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 Underling Stock’s and/or Fund’s shares inadvisable. In addition, trading in Underlying Stock’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] | Tracking Error Risk: Tracking error is the divergence of the Fund’s performance from that of its investment objective which aims to replicate 2 times the daily percentage change of the Underlying Stock. The performance of the Fund may diverge from that of its investment objective 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 Stock 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 as a result of market restrictions or other legal reasons, including regulatory limits or other restrictions on securities that may be purchased by the Adviser and its affiliates.

| Risk [Text Block] | Tax Risk: 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, particularly because the Fund’s investment objective focuses on the performance of the stock of a single issuer. 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] | Underlying Stock Risk: The performance of the Underlying Stock, and consequently the Fund’s performance, is subject to the risks of the electronic data processing industry. Any data breaches, unauthorized access, data loss due to system malfunctions, cyberattacks, privacy violations, data integrity issues, system outages, hardware failures, software vulnerabilities, human error, and power disruptions; essentially, any threat that could compromise the confidentiality, integrity, or availability of stored or processed data could have a material adverse effect on our company, its prospects and financial performance. Worldwide economic conditions could have an effect on the demand for our company’s services and products and could result in declining revenue and earnings. General economic declines or a softening of the economy make it more likely that our company may experience difficulties collecting accounts receivable, sales and demand for our company’s products may decrease, and our company’s operating results may be adversely affected. The Fund’s daily returns may be affected by many factors but will depend on the performance and volatility of the Underlying Stock.

| GraniteShares 2x Long RDDT Daily ETF Summary | Effects Of Compounding And Market Volatility Risk [Member] | ||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||
| Prospectus [Line Items] | ||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||
| Risk [Text Block] | Effects of Compounding and Market Volatility Risk: The Fund aims to replicate the leverage daily returns of the Underlying Stock 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 Underlying Stock’s performance, before fees and expenses. Compounding affects all investments but has a more significant impact on funds that aims to replicate leverage daily returns. For a Fund aiming to replicate 2 times the daily performance of an Underlying Stock, if adverse daily performance of the Underlying Stock 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 the favorable daily performance of the Underlying Stock 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 pronounced as the Underlying Stock 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 Stock during the shareholder’s holding period of an investment in the Fund.
The chart below provides examples of how Underlying Stock volatility could affect the Fund’s performance. Fund performance for periods greater than one single day can be estimated given any set of assumptions for the following factors: a) Underlying Stock volatility; b) Underlying Stock’s performance; c) period of time; d) financing rates associated with leveraged exposure; e) other Fund expenses; and f) the Underlying Stock’s dividends. The chart below illustrates the impact of two principal factors – Underlying Stock volatility and performance – on Fund performance. The chart shows estimated Fund returns for a number of combinations of Underlying Stock volatility and performance over a one-year period. Performance shown in the chart assumes that (i) there were no Fund expenses; and (ii) borrowing rates (needed to obtain a leveraged long exposure) of 0%. If Fund expenses and/or actual borrowing/lending rates were reflected, the estimated returns would be lower than those shown. Particularly during periods of higher Underlying Stock volatility, compounding will cause results for periods longer than a trading day to vary from the performance of the Underlying Stock.
As shown in the chart below, the Fund would be expected to lose 6.0% if the Underlying Stock provided no return over a one-year period during which the Underlying Stock experienced annualized volatility of 25%. At higher ranges of volatility, there is a chance of a significant loss of value in the Fund, even if the Underlying Stock return is flat.
For instance, if the Underlying Stock’s annualized volatility is 100%, the Fund would be expected to lose 63.3% of its value, even if the cumulative Underlying Stock’s return for the year was 0%. Areas shaded red (or dark gray) represent those scenarios where the Fund can be expected to return less than 200% of the performance of the Underlying Stock and those shaded green (or light gray) represent those scenarios where the Fund can be expected to return more than -200% of the performance of the Underlying Stock. The Fund’s actual returns may be significantly better or worse than the returns shown below as a result of any of the factors discussed above or in “Tracking Error Risk” below.
The Underlying Stock’s annualized historical volatility rate for period starting March 20, 2024 (date of the Underlying Stock’s IPO) to August 31, 2025, was 98.3%. During the period observed the Underlying Stock’s highest volatility rate over a 12-month period was 107.8% and volatility for a shorter period of time may have been substantially higher. The Underlying Stock’s annualized performance for the period starting March 20, 2024 (date of the Underlying Stock’s IPO) to August 31, 2025 was 270.3%. Historical volatility and performance are not indications of what the Underlying Stock volatility and performance will be in the future. The volatility of instruments that reflect the value of the Underlying Stock, such as swaps, may differ from the volatility of the Underlying Stock.

| Risk [Text Block] | Correlation Risk: A number of factors may affect the Fund’s ability to achieve a high degree of correlation with Underlying Stock, and there is no guarantee that the Fund will achieve a high degree of correlation. Failure to achieve a high degree of correlation may prevent the Fund from achieving its investment objective, and the percentage change of the Fund’s NAV each day may differ, perhaps significantly in amount, and possibly even direction, from -200% of the percentage change of Underlying Stock on such day.
In order to achieve a high degree of correlation with Underlying Stock, the Fund seeks to rebalance its portfolio daily to keep exposure consistent with its investment objective. Being materially under- or overexposed to Underlying Stock may prevent the Fund from achieving a high degree of correlation with the Underlying Stock and may expose the Fund to greater leverage risk. Market disruptions or closure, regulatory restrictions, market volatility, illiquidity in the markets for the financial instruments in which the Fund invests, and other factors will adversely affect the Fund’s ability to adjust exposure to requisite levels. The target amount of portfolio exposure is impacted dynamically by Underlying Stock’s movements, including intraday movements. Because of this, it is unlikely that the Fund will have perfect 200% exposure during the day or at the end of each day and the likelihood of being materially under- or overexposed is higher on days when Underlying Stock is volatile, particularly when Underlying Stock is volatile at or near the close of the trading day.
A number of other factors may also adversely affect the Fund’s correlation with the Underlying Stock, including fees, expenses, transaction costs, financing costs associated with the use of derivatives, income items, valuation methodology, accounting standards and disruptions or illiquidity in the markets for the securities or financial instruments in which the Fund invests. The Fund may take or refrain from taking positions in order to improve tax efficiency, comply with regulatory restrictions, or for other reasons, each of which may negatively affect the Fund’s correlation with Underlying Stock. The Fund may also be subject to large movements of assets into and out of the Fund, potentially resulting in the Fund being under- or overexposed to Underlying Stock. Additionally, the Fund’s underlying investments and/or reference assets may trade on markets that may not be open on the same day as the Fund, which may cause a difference between the changes in the daily performance of the Fund and changes in the performance of Underlying Stock. Any of these factors could decrease correlation between the performance of the Fund and Underlying Stock and may hinder the Fund’s ability to meet its daily investment objective on or around that day.

| 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 Stock 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 Underlying Stock, 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 Underlying Stock declines more than 50%. Leverage will also have the effect of magnifying any differences in the Fund performance’s correlation with the Underlying Stock.
Due to the limited availability of necessary investments or financial instruments, the Fund could, among other things, as a defensive measure, limit or suspend creations or redemptions of Creation Units until the adviser determines that the requisite exposure to the underlying Stock is obtainable. During the period that creation or redemptions are affected, the Fund’s shares could trade at a significant premium or discount to their net asset value, or the bid-ask spread of the Fund’s shares could widen significantly. In the case of a period during which creations are suspended, the Fund could experience significant redemptions, which may cause the Fund to sell portfolio securities at unfavorable prices and increased transaction and other costs and make greater taxable distributions to shareholders of the Fund.

| Risk [Text Block] | Derivatives Risk: The use of derivative instruments involves risks different from, or possibly greater than, the risks associated with investing directly in securities and other traditional investments. These risks include (i) the risk that the counterparty to a derivative transaction may not fulfill its contractual obligations; (ii) risk of mispricing or improper valuation; and (iii) the risk that changes in the value of the derivative may not correlate perfectly with the underlying asset, rate or index. Derivative prices are highly volatile and may fluctuate substantially during a short period of time. Such prices are influenced by numerous factors that affect the markets, including, but not limited to: changing supply and demand relationships; government programs and policies; national and international political and economic events, changes in interest rates, inflation and deflation and changes in supply and demand relationships. Trading derivative instruments involves risks different from, or possibly greater than, the risks associated with investing directly in securities.

| 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] | Market and Geopolitical Risk: The increasing interconnectivity between global economies and financial markets increases the likelihood that events or conditions in one region or financial market may adversely impact issuers in a different country, region or financial market. Securities in the Fund’s portfolio may underperform due to inflation (or expectations for inflation), interest rates, global demand for particular products or resources, natural disasters, pandemics, epidemics, terrorism, regulatory events and governmental or quasi-governmental actions. The occurrence of global events similar to those in recent years, such as terrorist attacks around the world, natural disasters, social and political discord or debt crises and downgrades, among others, may result in market volatility and may have long term effects on both the U.S. and global financial markets. It is difficult to predict when similar events affecting the U.S. or global financial markets may occur, the effects that such events may have and the duration of those effects.

The prices of options are volatile and are influenced by, among other things, actual and anticipated changes in the value of the underlying instrument, including the anticipated volatility, which are affected by fiscal and monetary policies and by national and international political, changes in the actual or implied volatility or the reference asset, the time remaining until the expiration of the option contract and economic events. For the Fund, in particular, the value of the options contracts in which it invests is substantially influenced by the value of the Underlying Stock. The Fund may experience substantial downside from specific option positions and certain option positions held by the Fund may expire worthless. As an option approaches its expiration date, its value typically increasingly moves with the value of the underlying instrument. However, prior to such a date, the value of an option generally does not increase or decrease at the same rate at the underlying instrument. There may at times be an imperfect correlation between the movement in values of 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. Furthermore, when the Fund seeks to trade out of positions, especially near expiration, there is an added risk that the Fund may be required to allocate resources unexpectedly to fulfill these obligations. This potential exposure to physical settlement can significantly impact the Fund’s liquidity and market exposure, particularly in volatile market conditions. If the Fund sells non-cash settled options contracts, it would be obligated to receive shares of the Underlying Stock when the option is exercised. Consequently, there is a risk that the Fund may have to physically acquire the Underlying Stock shares at the strike price, which could result in the Fund holding the Underlying Stock, and an asset that has declined in value. The level of exposure obtained through option contracts should at most be equal to the Fund’s Daily Leverage Factor times the Fund’s net asset value.

| 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 Stock that is significantly greater or less than its stated multiple. As a result, the Fund may be more exposed to leverage risk than if it had been properly rebalanced and may not achieve its investment objective.

| Risk [Text Block] | Trading Halt Risk: Although the Underlying Stock’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 Stock’s shares is expected, in turn, to result in a halt in the trading in the Fund’s shares. Trading in the Underlying Stock’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 Underling Stock’s and/or Fund’s shares inadvisable. In addition, trading in Underlying Stock’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] | Tracking Error Risk: Tracking error is the divergence of the Fund’s performance from that of its investment objective which aims to replicate -2 times the inverse daily percentage change of the Underlying Stock. The performance of the Fund may diverge from that of its investment objective 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 Stock 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 as a result of market restrictions or other legal reasons, including regulatory limits or other restrictions on securities that may be purchased by the Adviser and its affiliates.

| Risk [Text Block] | Tax Risk: 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, particularly because the Fund’s investment objective focuses on the performance of the stock of a single issuer. 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] | Underlying Stock Risk: The performance of the Underlying Stock, and consequently the Fund’s performance, is subject to the risks of the capital market services industry. The Underlying Stock is subject to many risks that can negatively impact its revenue and viability including stock and bank trading activity, changes in governmental regulation, continuing increases in price competition, decreases in fees or fee related business, including investment banking, brokerage, asset management and other servicing fees, fluctuation in interest rates and other factors which could adversely affect financial markets. Companies in the capital market services industry are facing increased government and regulatory scrutiny and may be subject to adverse government or regulatory action. The Fund’s daily returns may be affected by many factors but will depend on the performance and volatility of the Underlying Stock.

| Prospectus [Line Items] | ||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||
| Risk [Text Block] | Effects of Compounding and Market Volatility Risk: The Fund aims to replicate the daily leverage returns of the Underlying Stock 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 Underlying Stock’s performance, before fees and expenses. Compounding affects all investments but has a more significant impact on funds that aims to replicate daily leverage returns. For a Fund aiming to replicate 2 times the daily performance of an Underlying Stock, if adverse daily performance of the Underlying Stock 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 the favorable daily performance of the Underlying Stock 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 pronounced as the Underlying Stock 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 Stock during the shareholder’s holding period of an investment in the Fund.
The chart below provides examples of how Underlying Stock volatility could affect the Fund’s performance. Fund performance for periods greater than one single day can be estimated given any set of assumptions for the following factors: a) Underlying Stock volatility; b) Underlying Stock’s performance; c) period of time; d) financing rates associated with leveraged exposure; e) other Fund expenses; and f) the Underlying Stock’s dividends. The chart below illustrates the impact of two principal factors – Underlying Stock volatility and performance – on Fund performance. The chart shows estimated Fund returns for a number of combinations of Underlying Stock volatility and performance over a one-year period. Performance shown in the chart assumes that (i) there were no Fund expenses; and (ii) borrowing rates (needed to obtain a leveraged long exposure) of 0%. If Fund expenses and/or actual borrowing/lending rates were reflected, the estimated returns would be lower than those shown. Particularly during periods of higher Underlying Stock volatility, compounding will cause results for periods longer than a trading day to vary from the performance of the Underlying Stock.
As shown in the chart below, the Fund would be expected to lose 17.0% if the Underlying Stock provided no return over a one-year period during which the Underlying Stock experienced annualized volatility of 25%. At higher ranges of volatility, there is a chance of a significant loss of value in the Fund, even if the Underlying Stock return is flat.
For instance, if the Underlying Stock’s annualized volatility is 100%, the Fund would be expected to lose 63.3% of its value, even if the cumulative Underlying Stock’s return for the year was 0%. Areas shaded red (or dark gray) represent those scenarios where the Fund can be expected to return less than 200% of the performance of the Underlying Stock and those shaded green (or light gray) represent those scenarios where the Fund can be expected to return more than 200% of the performance of the Underlying Stock. The Fund’s actual returns may be significantly better or worse than the returns shown below as a result of any of the factors discussed above or in “Tracking Error Risk” below.
The Underlying Stock’s annualized historical volatility rate for the five-year period ended August 31, 2025, was 111.7%. During the five-year period observed the Underlying Stock’s highest volatility rate over a 12-month period was 155.8% and volatility for a shorter period of time may have been substantially higher. The Underlying Stock’s annualized performance for the five-year period ended August 31, 2025, was 25.4%. Historical volatility and performance are not indications of what the Underlying Stock volatility and performance will be in the future. The volatility of instruments that reflect the value of the Underlying Stock, such as swaps, may differ from the volatility of the Underlying Stock.

| Risk [Text Block] | Correlation Risk: A number of factors may affect the Fund’s ability to achieve a high degree of correlation with Underlying Stock, and there is no guarantee that the Fund will achieve a high degree of correlation. Failure to achieve a high degree of correlation may prevent the Fund from achieving its investment objective, and the percentage change of the Fund’s NAV each day may differ, perhaps significantly in amount, and possibly even direction, from 200% of the percentage change of Underlying Stock on such day.
In order to achieve a high degree of correlation with Underlying Stock, the Fund seeks to rebalance its portfolio daily to keep exposure consistent with its investment objective. Being materially under- or overexposed to Underlying Stock may prevent the Fund from achieving a high degree of correlation with the Underlying Stock and may expose the Fund to greater leverage risk. Market disruptions or closure, regulatory restrictions, market volatility, illiquidity in the markets for the financial instruments in which the Fund invests, and other factors will adversely affect the Fund’s ability to adjust exposure to requisite levels. The target amount of portfolio exposure is impacted dynamically by Underlying Stock’s movements, including intraday movements. Because of this, it is unlikely that the Fund will have perfect 200% exposure during the day or at the end of each day and the likelihood of being materially under- or overexposed is higher on days when Underlying Stock is volatile, particularly when Underlying Stock is volatile at or near the close of the trading day.
A number of other factors may also adversely affect the Fund’s correlation with the Underlying Stock, including fees, expenses, transaction costs, financing costs associated with the use of derivatives, income items, valuation methodology, accounting standards and disruptions or illiquidity in the markets for the securities or financial instruments in which the Fund invests. The Fund may take or refrain from taking positions in order to improve tax efficiency, comply with regulatory restrictions, or for other reasons, each of which may negatively affect the Fund’s correlation with Underlying Stock. The Fund may also be subject to large movements of assets into and out of the Fund, potentially resulting in the Fund being under- or overexposed to Underlying Stock. Additionally, the Fund’s underlying investments and/or reference assets may trade on markets that may not be open on the same day as the Fund, which may cause a difference between the changes in the daily performance of the Fund and changes in the performance of Underlying Stock. Any of these factors could decrease correlation between the performance of the Fund and Underlying Stock and may hinder the Fund’s ability to meet its daily investment objective on or around that day.

| 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 Stock 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 Underlying Stock, 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 Underlying Stock declines more than 50%. Leverage will also have the effect of magnifying any differences in the Fund performance’s correlation with the Underlying Stock.
Due to the limited availability of necessary investments or financial instruments, the Fund could, among other things, as a defensive measure, limit or suspend creations or redemptions of Creation Units until the adviser determines that the requisite exposure to the underlying Stock is obtainable. During the period that creation or redemptions are affected, the Fund’s shares could trade at a significant premium or discount to their net asset value, or the bid-ask spread of the Fund’s shares could widen significantly. In the case of a period during which creations are suspended, the Fund could experience significant redemptions, which may cause the Fund to sell portfolio securities at unfavorable prices and increased transaction and other costs and make greater taxable distributions to shareholders of the Fund.

| Risk [Text Block] | Derivatives Risk: The use of derivative instruments involves risks different from, or possibly greater than, the risks associated with investing directly in securities and other traditional investments. These risks include (i) the risk that the counterparty to a derivative transaction may not fulfill its contractual obligations; (ii) risk of mispricing or improper valuation; and (iii) the risk that changes in the value of the derivative may not correlate perfectly with the underlying asset, rate or index. Derivative prices are highly volatile and may fluctuate substantially during a short period of time. Such prices are influenced by numerous factors that affect the markets, including, but not limited to: changing supply and demand relationships; government programs and policies; national and international political and economic events, changes in interest rates, inflation and deflation and changes in supply and demand relationships. Trading derivative instruments involves risks different from, or possibly greater than, the risks associated with investing directly in securities.

The Fund will be subject to regulatory constraints relating to the level of value at risk that the Fund may incur through its derivative portfolio.

| 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] | Market and Geopolitical Risk: The increasing interconnectivity between global economies and financial markets increases the likelihood that events or conditions in one region or financial market may adversely impact issuers in a different country, region or financial market. Securities in the Fund’s portfolio may underperform due to inflation (or expectations for inflation), interest rates, global demand for particular products or resources, natural disasters, pandemics, epidemics, terrorism, regulatory events and governmental or quasi-governmental actions. The occurrence of global events similar to those in recent years, such as terrorist attacks around the world, natural disasters, social and political discord or debt crises and downgrades, among others, may result in market volatility and may have long term effects on both the U.S. and global financial markets. It is difficult to predict when similar events affecting the U.S. or global financial markets may occur, the effects that such events may have and the duration of those effects.

| Risk [Text Block] | Options Contracts Risk: The use of options contracts involves investment strategies and risks different from those associated with ordinary portfolio securities transactions. The prices of options are volatile and are influenced by, among other things, actual and anticipated changes in the value of the underlying instrument, including the anticipated volatility, which are affected by fiscal and monetary policies and by national and international political, changes in the actual or implied volatility or the reference asset, the time remaining until the expiration of the option contract and economic events. For the Fund, in particular, the value of the options contracts in which it invests is substantially influenced by the value of the Underlying Stock. The Fund may experience substantial downside from specific option positions and certain option positions held by the Fund may expire worthless. As an option approaches its expiration date, its value typically increasingly moves with the value of the underlying instrument. However, prior to such a date, the value of an option generally does not increase or decrease at the same rate at the underlying instrument. There may at times be an imperfect correlation between the movement in values of 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. Furthermore, when the Fund seeks to trade out of positions, especially near expiration, there is an added risk that the Fund may be required to allocate resources unexpectedly to fulfill these obligations. This potential exposure to physical settlement can significantly impact the Fund’s liquidity and market exposure, particularly in volatile market conditions. If the Fund sells non-cash settled options contracts, it would be obligated to receive shares of the Underlying Stock when the option is exercised. Consequently, there is a risk that the Fund may have to physically acquire the Underlying Stock shares at the strike price, which could result in the Fund holding the Underlying Stock, and an asset that has declined in value. The level of exposure obtained through option contracts should at most be equal to the Fund’s Daily Leverage Factor times the Fund’s net asset value.

The performance of the Fund may diverge from that of its investment objective 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 Stock 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 as a result of market restrictions or other legal reasons, including regulatory limits or other restrictions on securities that may be purchased by the Adviser and its affiliates.

| Risk [Text Block] | Tax Risk: 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, particularly because the Fund’s investment objective focuses on the performance of the stock of a single issuer. 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] | Bitcoin Risk: The performance of the Underlying Stock, and consequently the Fund’s performance, is subject to risks associated with bitcoin. Investing in bitcoin exposes 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. Bitcoin is not presently widely accepted as a medium of exchange, which may be due to a number of common impediments and/or disadvantages to adopting the Bitcoin Network as a payment network, including the slowness of transaction processing and finality, variability of transaction fees, and volatility of the price of bitcoin. Additionally, risks associated with the sale of newly mined bitcoin, bitcoin trading platforms, competition from alternative digital assets, mining operations, network modifications, and intellectual property claims pose further challenges to bitcoin-linked investments. The value of bitcoin has been, may continue to be, substantially dependent on speculation, such that trading and investing in these assets generally may not be based on fundamental analysis. The Fund’s daily returns may be affected by many factors but will depend on the performance and volatility of the Underlying Stock.

| Risk [Text Block] | Bitcoin Halving. While bitcoin prices have historically increased around halving events (a process designed to control the overall supply and reduce the risk of inflation in bitcoin, which uses a proof-of-work consensus algorithm and results in the mining reward being cut in half) there is no guarantee that the price change will be favorable or would compensate for the reduction in mining rewards. If a corresponding and proportionate increase in the price of Bitcoin does not follow future halving events, the revenue RIOT earns from its bitcoin mining operations would see a decrease, which could have a material adverse effect on RIOT’s results of operations and financial condition.

| Risk [Text Block] | Hash Rate and Difficulty. As demand for bitcoin has increased, the global network hash rate (i.e., the aggregate amount of computing power devoted to supporting the bitcoin blockchain at a given time) has increased rapidly, and as greater adoption of bitcoin occurs, it is expected that demand for new bitcoin will likewise increase as more mining companies are drawn into the industry by this increased demand. Further, as a greater number of increasingly powerful miners have been deployed, the network difficulty for bitcoin has consequently also increased. A high difficulty means that more computing power will be required in order to solve a block and earn a new bitcoin reward, which, in turn, makes the bitcoin network more secure by limiting the possibility of one miner or mining pool gaining control of the network. Therefore, as new and existing miners deploy additional hash rate, the global network hash rate will continue to increase, meaning a miner’s share of the global network hash rate (and therefore its chance of earning bitcoin rewards) will decline if it fails to deploy additional hash rate at pace with the industry. If an effort to grow the hash rate, results in the inability to complete planned expansions on schedule and within anticipated cost estimates, deployment of newly purchased miners may be delayed, which could affect its competitiveness and results of operation, which could have a material adverse effect on the Underlying Stock’s financial condition and market price for its securities.

| Risk [Text Block] | Blockchain Risk: Blockchain companies may be adversely impacted by government regulations or economic conditions. Blockchain technology is new and its uses are in many cases untested or unclear. These companies may also have significant exposure to fluctuations in the spot prices of digital assets, particularly to the extent that demand for a company’s hardware or services may increase as the spot price of digital assets increase. Blockchain companies typically face intense competition and potentially rapid product obsolescence. In addition, many Blockchain companies store sensitive consumer information and could be the target of cybersecurity attacks and other types of theft, which could have a negative impact on these companies. Access to a given blockchain may require a specific cryptographic key (in effect a string of characters granting unique access to initiate transactions related to specific digital assets) or set of keys, the theft, loss, or destruction of which, either by accident or as a result of the efforts of a third party, could irrevocably impair a claim to the digital assets stored on that blockchain. Many Blockchain companies currently operate under less regulatory scrutiny than traditional financial services companies and banks, but there is significant risk that regulatory oversight could increase in the future. Higher levels of regulation could increase costs and adversely impact the current business models of some Blockchain companies. For example, restrictions imposed by foreign governments, including China, on the use and mining of digital assets, may adversely impact Blockchain Companies and in turn the Fund. These companies could be negatively impacted by disruptions in service caused by hardware or software failure, or by interruptions or delays in service by third-party data center hosting facilities and maintenance providers. Blockchain companies involved in digital assets may face slow adoption rates and be subject to higher levels of regulatory scrutiny in the future, which could severely impact the viability of these companies. Blockchain companies, especially smaller companies, tend to be more volatile than companies that do not rely heavily on technology. The customers and/or suppliers of Blockchain companies may be concentrated in a particular country, region or industry. Any adverse event affecting one of these countries, regions or industries could have a negative impact on Blockchain companies.

| Risk [Text Block] | Underlying Stock Risk: The performance of the Underlying Stock, and consequently the Fund’s performance, is subject to the risks of the investment banking and brokerage industry. The Underlying Stock is subject to many risks that can negatively impact its revenue and viability including, but are not limited to price volatility risk, management risk, inflation risk, global economic risk, growth risk, supply and demand risk, operations risk, regulatory risk, environmental risk, terrorism risk and the risk of natural disasters. The Underlying Stock operates in a heavily regulated and supervised environment. The impact interpretation, and enforcement of new rules can have major impacts on its operations. The Underlying Stock has material exposure to market, credit, and liquidity risks. The Underlying Stock relies on complex systems, and its inability to operate them accurately and timely could materially impact its ability to operate. The Underlying Stock may be significantly affected by stock and bank trading activity, continuing increases in price competition, decreases in fees or fee-related business, including investment banking, brokerage, asset management and other servicing fees, fluctuation in interest rates and other factors which could adversely affect financial markets. The Fund’s daily returns may be affected by many factors but will depend on the performance and volatility of the Underlying Stock.

| Prospectus [Line Items] | ||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||
| Risk [Text Block] | Effects of Compounding and Market Volatility Risk: The Fund aims to replicate the daily leverage returns of the Underlying Stock 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 Underlying Stock’s performance, before fees and expenses. Compounding affects all investments but has a more significant impact on funds that aims to replicate leverage daily returns. For a Fund aiming to replicate 2 times the daily performance of an Underlying Stock, if adverse daily performance of the Underlying Stock 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 the favorable daily performance of the Underlying Stock 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 pronounced as the Underlying Stock 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 Stock during the shareholder’s holding period of an investment in the Fund.
The chart below provides examples of how Underlying Stock volatility could affect the Fund’s performance. Fund performance for periods greater than one single day can be estimated given any set of assumptions for the following factors: a) Underlying Stock volatility; b) Underlying Stock’s performance; c) period of time; d) financing rates associated with leveraged exposure; e) other Fund expenses; and f) the Underlying Stock’s dividends. The chart below illustrates the impact of two principal factors – Underlying Stock volatility and performance – on Fund performance. The chart shows estimated Fund returns for a number of combinations of Underlying Stock volatility and performance over a one-year period. Performance shown in the chart assumes that (i) there were no Fund expenses; and (ii) borrowing rates (needed to obtain a leveraged long exposure) of 0%. If Fund expenses and/or actual borrowing/lending rates were reflected, the estimated returns would be lower than those shown. Particularly during periods of higher Underlying Stock volatility, compounding will cause results for periods longer than a trading day to vary from the performance of the Underlying Stock.
As shown in the chart below, the Fund would be expected to lose 6.0% if the Underlying Stock provided no return over a one-year period during which the Underlying Stock experienced annualized volatility of 25%. At higher ranges of volatility, there is a chance of a significant loss of value in the Fund, even if the Underlying Stock return is flat.
For instance, if the Underlying Stock’s annualized volatility is 100%, the Fund would be expected to lose 63.3% of its value, even if the cumulative Underlying Stock’s return for the year was 0%. Areas shaded red (or dark gray) represent those scenarios where the Fund can be expected to return less than 200% of the performance of the Underlying Stock and those shaded green (or light gray) represent those scenarios where the Fund can be expected to return more than 200% of the performance of the Underlying Stock. The Fund’s actual returns may be significantly better or worse than the returns shown below as a result of any of the factors discussed above or in “Tracking Error Risk” below.
The Underlying Stock’s annualized historical volatility rate from July 28, 2021 (Underlying Stock’s IPO date) August 31, 2025, was 75.6%. During the period observed the Underlying Stock’s highest volatility rate over a 12-month period was 103.8% and volatility for a shorter period of time may have been substantially higher. The Underlying Stock’s annualized performance for the period considered was 27.9%. Historical volatility and performance are not indications of what the Underlying Stock volatility and performance will be in the future. The volatility of instruments that reflect the value of the Underlying Stock, such as swaps, may differ from the volatility of the Underlying Stock.

| Risk [Text Block] | Correlation Risk: A number of factors may affect the Fund’s ability to achieve a high degree of correlation with Underlying Stock, and there is no guarantee that the Fund will achieve a high degree of correlation. Failure to achieve a high degree of correlation may prevent the Fund from achieving its investment objective, and the percentage change of the Fund’s NAV each day may differ, perhaps significantly in amount, and possibly even direction, from 200% of the percentage change of Underlying Stock on such day.
In order to achieve a high degree of correlation with Underlying Stock, the Fund seeks to rebalance its portfolio daily to keep exposure consistent with its investment objective. Being materially under- or overexposed to Underlying Stock may prevent the Fund from achieving a high degree of correlation with Underlying Stock and may expose the Fund to greater leverage risk. Market disruptions or closure, regulatory restrictions, market volatility, illiquidity in the markets for the financial instruments in which the Fund invests, and other factors will adversely affect the Fund’s ability to adjust exposure to requisite levels. The target amount of portfolio exposure is impacted dynamically by Underlying Stock’s movements, including intraday movements. Because of this, it is unlikely that the Fund will have perfect -100% exposure during the day or at the end of each day and the likelihood of being materially under- or overexposed is higher on days when Underlying Stock is volatile, particularly when Underlying Stock is volatile at or near the close of the trading day.
A number of other factors may also adversely affect the Fund’s correlation with Underlying Stock, including fees, expenses, transaction costs, financing costs associated with the use of derivatives, income items, valuation methodology, accounting standards and disruptions or illiquidity in the markets for the securities or financial instruments in which the Fund invests. The Fund may take or refrain from taking positions in order to improve tax efficiency, comply with regulatory restrictions, or for other reasons, each of which may negatively affect the Fund’s correlation with Underlying Stock. The Fund may also be subject to large movements of assets into and out of the Fund, potentially resulting in the Fund being under- or overexposed to Underlying Stock. Additionally, the Fund’s underlying investments and/or reference assets may trade on markets that may not be open on the same day as the Fund, which may cause a difference between the changes in the daily performance of the Fund and changes in the performance of Underlying Stock. Any of these factors could decrease correlation between the performance of the Fund and Underlying Stock and may hinder the Fund’s ability to meet its daily investment objective on or around that day.

| 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 Stock 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 Underlying Stock, 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 Underlying Stock declines more than 50%. Leverage will also have the effect of magnifying any differences in the Fund performance’s correlation with the Underlying Stock.
Due to the limited availability of necessary investments or financial instruments, the Fund could, among other things, as a defensive measure, limit or suspend creations or redemptions of Creation Units until the adviser determines that the requisite exposure to the underlying Stock is obtainable. During the period that creation or redemptions are affected, the Fund’s shares could trade at a significant premium or discount to their net asset value, or the bid-ask spread of the Fund’s shares could widen significantly. In the case of a period during which creations are suspended, the Fund could experience significant redemptions, which may cause the Fund to sell portfolio securities at unfavorable prices and increased transaction and other costs and make greater taxable distributions to shareholders of the Fund.

| Risk [Text Block] | Derivatives Risk: The use of derivative instruments involves risks different from, or possibly greater than, the risks associated with investing directly in securities and other traditional investments. These risks include (i) the risk that the counterparty to a derivative transaction may not fulfill its contractual obligations; (ii) risk of mispricing or improper valuation; and (iii) the risk that changes in the value of the derivative may not correlate perfectly with the underlying asset, rate or index. Derivative prices are highly volatile and may fluctuate substantially during a short period of time. Such prices are influenced by numerous factors that affect the markets, including, but not limited to: changing supply and demand relationships; government programs and policies; national and international political and economic events, changes in interest rates, inflation and deflation and changes in supply and demand relationships. Trading derivative instruments involves risks different from, or possibly greater than, the risks associated with investing directly in securities.

The Fund will be subject to regulatory constraints relating to the level of value at risk that the Fund may incur through its derivative portfolio.

| 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] | Market and Geopolitical Risk: The increasing interconnectivity between global economies and financial markets increases the likelihood that events or conditions in one region or financial market may adversely impact issuers in a different country, region or financial market. Securities in the Fund’s portfolio may underperform due to inflation (or expectations for inflation), interest rates, global demand for particular products or resources, natural disasters, pandemics, epidemics, terrorism, regulatory events and governmental or quasi-governmental actions. The occurrence of global events similar to those in recent years, such as terrorist attacks around the world, natural disasters, social and political discord or debt crises and downgrades, among others, may result in market volatility and may have long term effects on both the U.S. and global financial markets. It is difficult to predict when similar events affecting the U.S. or global financial markets may occur, the effects that such events may have and the duration of those effects.

| Risk [Text Block] | Options Contracts Risk: The use of options contracts involves investment strategies and risks different from those associated with ordinary portfolio securities transactions. The prices of options are volatile and are influenced by, among other things, actual and anticipated changes in the value of the underlying instrument, including the anticipated volatility, which are affected by fiscal and monetary policies and by national and international political, changes in the actual or implied volatility or the reference asset, the time remaining until the expiration of the option contract and economic events. For the Fund, in particular, the value of the options contracts in which it invests is substantially influenced by the value of the Underlying Stock. The Fund may experience substantial downside from specific option positions and certain option positions held by the Fund may expire worthless. As an option approaches its expiration date, its value typically increasingly moves with the value of the underlying instrument. However, prior to such a date, the value of an option generally does not increase or decrease at the same rate at the underlying instrument. There may at times be an imperfect correlation between the movement in values of 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. Furthermore, when the Fund seeks to trade out of positions, especially near expiration, there is an added risk that the Fund may be required to allocate resources unexpectedly to fulfill these obligations. This potential exposure to physical settlement can significantly impact the Fund’s liquidity and market exposure, particularly in volatile market conditions. If the Fund sells non-cash settled options contracts, it would be obligated to receive shares of the Underlying Stock when the option is exercised. Consequently, there is a risk that the Fund may have to physically acquire the Underlying Stock shares at the strike price, which could result in the Fund holding the Underlying Stock, and an asset that has declined in value. The level of exposure obtained through option contracts should at most be equal to the Fund’s Daily Leverage Factor times the Fund’s net asset value.

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

| Risk [Text Block] | Trading Halt Risk: Although the Underlying Stock’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 Stock’s shares is expected, in turn, to result in a halt in the trading in the Fund’s shares. Trading in the Underlying Stock’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 Underling Stock’s and/or Fund’s shares inadvisable. In addition, trading in Underlying Stock’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] | Tracking Error Risk: Tracking error is the divergence of the Fund’s performance from that of its investment objective which aims to replicate 2 times the daily percentage change of the Underlying Stock. The performance of the Fund may diverge from that of its investment objective 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 Stock 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 as a result of market restrictions or other legal reasons, including regulatory limits or other restrictions on securities that may be purchased by the Adviser and its affiliates.

| Risk [Text Block] | Tax Risk: 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, particularly because the Fund’s investment objective focuses on the performance of the stock of a single issuer. 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] | Underlying Stock Risk: The Underlying Stock is subject to many risks that can negatively impact its revenue and viability including, but are not limited to price volatility risk, management risk, inflation risk, global economic risk, growth risk, supply and demand risk, operations risk, regulatory risk, environmental risk, terrorism risk and the risk of natural disasters. The Underlying Stock performance may be affected by competition in the microprocessor market, reliance on third-party manufacturers, the company’s ability to new develop new products, losses of significant customers, changes in customer demand for its products, risks associated with defective products political, legal and economic risks affecting the company’s global operations. The Fund’s daily returns may be affected by many factors but will depend on the performance and volatility of the Underlying Stock.

| Prospectus [Line Items] | ||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||
| Risk [Text Block] | Effects of Compounding and Market Volatility Risk: The Fund aims to replicate the daily leverage returns of the Underlying Stock 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 Underlying Stock’s performance, before fees and expenses. Compounding affects all investments but has a more significant impact on funds that aims to replicate daily leverage returns. For a Fund aiming to replicate 2 times the daily performance of an Underlying Stock, if adverse daily performance of the Underlying Stock 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 the favorable daily performance of the Underlying Stock 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 pronounced as the Underlying Stock 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 Stock during the shareholder’s holding period of an investment in the Fund.
The chart below provides examples of how Underlying Stock volatility could affect the Fund’s performance. Fund performance for periods greater than one single day can be estimated given any set of assumptions for the following factors: a) Underlying Stock volatility; b) Underlying Stock’s performance; c) period of time; d) financing rates associated with leveraged exposure; e) other Fund expenses; and f) the Underlying Stock’s dividends. The chart below illustrates the impact of two principal factors – Underlying Stock volatility and performance – on Fund performance. The chart shows estimated Fund returns for a number of combinations of Underlying Stock volatility and performance over a one-year period. Performance shown in the chart assumes that (i) there were no Fund expenses; and (ii) borrowing rates (needed to obtain a leveraged long exposure) of 0%. If Fund expenses and/or actual borrowing/lending rates were reflected, the estimated returns would be lower than those shown. Particularly during periods of higher Underlying Stock volatility, compounding will cause results for periods longer than a trading day to vary from the performance of the Underlying Stock.
As shown in the chart below, the Fund would be expected to lose 6.0% if the Underlying Stock provided no return over a one-year period during which the Underlying Stock experienced annualized volatility of 25%. At higher ranges of volatility, there is a chance of a significant loss of value in the Fund, even if the Underlying Stock return is flat.
For instance, if the Underlying Stock’s annualized volatility is 100%, the Fund would be expected to lose 63.3% of its value, even if the cumulative Underlying Stock’s return for the year was 0%. Areas shaded red (or dark gray) represent those scenarios where the Fund can be expected to return less than 200% of the performance of the Underlying Stock and those shaded green (or light gray) represent those scenarios where the Fund can be expected to return more than 200% of the performance of the Underlying Stock. The Fund’s actual returns may be significantly better or worse than the returns shown below as a result of any of the factors discussed above or in “Tracking Error Risk” below.
The Underlying Stock’s annualized historical volatility rate for the five-year period ended August 31, 2025, was 41.4%. During the five-year period observed the Underlying Stock’s highest volatility rate over a 12-month period was 52.3% and volatility for a shorter period of time may have been substantially higher. The Underlying Stock’s annualized performance for the five-year period ended August 31, 2025, was 13.1%. Historical volatility and performance are not indications of what the Underlying Stock volatility and performance will be in the future. The volatility of instruments that reflect the value of the Underlying Stock, such as swaps, may differ from the volatility of the Underlying Stock.

| Prospectus [Line Items] | ||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||
| Risk [Text Block] | Correlation Risk: A number of factors may affect the Fund’s ability to achieve a high degree of correlation with Underlying Stock, and there is no guarantee that the Fund will achieve a high degree of correlation. Failure to achieve a high degree of correlation may prevent the Fund from achieving its investment objective, and the percentage change of the Fund’s NAV each day may differ, perhaps significantly in amount, and possibly even direction, from 200% of the percentage change of Underlying Stock on such day.
In order to achieve a high degree of correlation with Underlying Stock, the Fund seeks to rebalance its portfolio daily to keep exposure consistent with its investment objective. Being materially under- or overexposed to Underlying Stock may prevent the Fund from achieving a high degree of correlation with Underlying Stock and may expose the Fund to greater leverage risk. Market disruptions or closure, regulatory restrictions, market volatility, illiquidity in the markets for the financial instruments in which the Fund invests, and other factors will adversely affect the Fund’s ability to adjust exposure to requisite levels. The target amount of portfolio exposure is impacted dynamically by Underlying Stock’s movements, including intraday movements. Because of this, it is unlikely that the Fund will have perfect 200% exposure during the day or at the end of each day and the likelihood of being materially under- or overexposed is higher on days when Underlying Stock is volatile, particularly when Underlying Stock is volatile at or near the close of the trading day.
A number of other factors may also adversely affect the Fund’s correlation with Underlying Stock, including fees, expenses, transaction costs, financing costs associated with the use of derivatives, income items, valuation methodology, accounting standards and disruptions or illiquidity in the markets for the securities or financial instruments in which the Fund invests. The Fund may take or refrain from taking positions in order to improve tax efficiency, comply with regulatory restrictions, or for other reasons, each of which may negatively affect the Fund’s correlation with Underlying Stock. The Fund may also be subject to large movements of assets into and out of the Fund, potentially resulting in the Fund being under- or overexposed to Underlying Stock. Additionally, the Fund’s underlying investments and/or reference assets may trade on markets that may not be open on the same day as the Fund, which may cause a difference between the changes in the daily performance of the Fund and changes in the performance of Underlying Stock. Any of these factors could decrease correlation between the performance of the Fund and Underlying Stock and may hinder the Fund’s ability to meet its daily investment objective on or around that day.

| 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 Stock 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 Underlying Stock, 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 Underlying Stock declines more than 50%. Leverage will also have the effect of magnifying any differences in the Fund performance’s correlation with the Underlying Stock.
Due to the limited availability of necessary investments or financial instruments, the Fund could, among other things, as a defensive measure, limit or suspend creations or redemptions of Creation Units until the adviser determines that the requisite exposure to the underlying Stock is obtainable. During the period that creation or redemptions are affected, the Fund’s shares could trade at a significant premium or discount to their net asset value, or the bid-ask spread of the Fund’s shares could widen significantly. In the case of a period during which creations are suspended, the Fund could experience significant redemptions, which may cause the Fund to sell portfolio securities at unfavorable prices and increased transaction and other costs and make greater taxable distributions to shareholders of the Fund.

| Risk [Text Block] | Derivatives Risk: The use of derivative instruments involves risks different from, or possibly greater than, the risks associated with investing directly in securities and other traditional investments. These risks include (i) the risk that the counterparty to a derivative transaction may not fulfill its contractual obligations; (ii) risk of mispricing or improper valuation; and (iii) the risk that changes in the value of the derivative may not correlate perfectly with the underlying asset, rate or index. Derivative prices are highly volatile and may fluctuate substantially during a short period of time. Such prices are influenced by numerous factors that affect the markets, including, but not limited to: changing supply and demand relationships; government programs and policies; national and international political and economic events, changes in interest rates, inflation and deflation and changes in supply and demand relationships. Trading derivative instruments involves risks different from, or possibly greater than, the risks associated with investing directly in securities.

The Fund will be subject to regulatory constraints relating to the level of value at risk that the Fund may incur through its derivative portfolio.

| 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] | Market and Geopolitical Risk: The increasing interconnectivity between global economies and financial markets increases the likelihood that events or conditions in one region or financial market may adversely impact issuers in a different country, region or financial market. Securities in the Fund’s portfolio may underperform due to inflation (or expectations for inflation), interest rates, global demand for particular products or resources, natural disasters, pandemics, epidemics, terrorism, regulatory events and governmental or quasi-governmental actions. The occurrence of global events similar to those in recent years, such as terrorist attacks around the world, natural disasters, social and political discord or debt crises and downgrades, among others, may result in market volatility and may have long term effects on both the U.S. and global financial markets. It is difficult to predict when similar events affecting the U.S. or global financial markets may occur, the effects that such events may have and the duration of those effects.

| Prospectus [Line Items] | ||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||
| Risk [Text Block] | Options Contracts Risk: The use of options contracts involves investment strategies and risks different from those associated with ordinary portfolio securities transactions. The prices of options are volatile and are influenced by, among other things, actual and anticipated changes in the value of the underlying instrument, including the anticipated volatility, which are affected by fiscal and monetary policies and by national and international political, changes in the actual or implied volatility or the reference asset, the time remaining until the expiration of the option contract and economic events. For the Fund, in particular, the value of the options contracts in which it invests is substantially influenced by the value of the Underlying Stock. The Fund may experience substantial downside from specific option positions and certain option positions held by the Fund may expire worthless. As an option approaches its expiration date, its value typically increasingly moves with the value of the underlying instrument. However, prior to such a date, the value of an option generally does not increase or decrease at the same rate at the underlying instrument. There may at times be an imperfect correlation between the movement in values of 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. Furthermore, when the Fund seeks to trade out of positions, especially near expiration, there is an added risk that the Fund may be required to allocate resources unexpectedly to fulfill these obligations. This potential exposure to physical settlement can significantly impact the Fund’s liquidity and market exposure, particularly in volatile market conditions. If the Fund sells non-cash settled options contracts, it would be obligated to receive shares of the Underlying Stock when the option is exercised. Consequently, there is a risk that the Fund may have to physically acquire the Underlying Stock shares at the strike price, which could result in the Fund holding the Underlying Stock, and an asset that has declined in value. The level of exposure obtained through option contracts should at most be equal to the Fund’s Daily Leverage Factor times the Fund’s net asset value.

In addition, the application of these requirements to the Fund’s investment objective is not clear, particularly because the Fund’s investment objective focuses on the performance of the stock of a single issuer. 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] | PRINCIPAL RISKS OF INVESTING IN THE FUND
As with all ETFs, there is the risk that you could lose money through your investment in the Fund. Many factors affect the Fund’s NAV and performance.

| Risk [Text Block] | Underlying Stock Risk: The Underlying Stock is subject to many risks that can negatively impact its revenue and viability including, but are not limited to price volatility risk, management risk, inflation risk, global economic risk, growth risk, supply and demand risk, operations risk, regulatory risk, environmental risk, terrorism risk and the risk of natural disasters. The Underlying Stock performance may be affected by competition in the microprocessor market, reliance on third-party manufacturers, the company’s ability to new develop new products, losses of significant customers, changes in customer demand for its products, risks associated with defective products political, legal and economic risks affecting the company’s global operations. The Fund’s daily returns may be affected by many factors but will depend on the performance and volatility of the Underlying Stock.

| Prospectus [Line Items] | ||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||
| Risk [Text Block] | Effects of Compounding and Market Volatility Risk: The Fund aims to replicate the leveraged daily returns of the Underlying Stock 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 the Underlying Stock’s performance, before fees and expenses. Compounding affects all investments but has a more significant impact on funds that aims to replicate leverage daily returns. For a Fund aiming to replicate 2 times the daily performance of an Underlying Stock, if adverse daily performance of the Underlying Stock 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 the favorable daily performance of the Underlying Stock 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 pronounced as the Underlying Stock 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 Stock during the shareholder’s holding period of an investment in the Fund.
The chart below provides examples of how Underlying Stock volatility could affect the Fund’s performance. Fund performance for periods greater than one single day can be estimated given any set of assumptions for the following factors: a) Underlying Stock volatility; b) Underlying Stock’s performance; c) period of time; d) financing rates associated with leveraged exposure; e) other Fund expenses; and f) the Underlying Stock’s dividends. The chart below illustrates the impact of two principal factors – Underlying Stock volatility and performance – on Fund performance. The chart shows estimated Fund returns for a number of combinations of Underlying Stock volatility and performance over a one-year period. Performance shown in the chart assumes that (i) there were no Fund expenses; and (ii) borrowing rates (needed to obtain a leveraged long exposure) of 0%. If Fund expenses and/or actual borrowing/lending rates were reflected, the estimated returns would be lower than those shown. Particularly during periods of higher Underlying Stock volatility, compounding will cause results for periods longer than a trading day to vary from the performance of the Underlying Stock.
As shown in the chart below, the Fund would be expected to lose 6.0 % if the Underlying Stock provided no return over a one-year period during which the Underlying Stock experienced annualized volatility of 25%. At higher ranges of volatility, there is a chance of a significant loss of value in the Fund, even if the Underlying Stock return is flat.
For instance, if the Underlying Stock annualized volatility is 100%, the Fund would be expected to lose 63.3% of its value, even if the cumulative Underlying Stock return for the year was 0%. Areas shaded red (or dark gray) represent those scenarios where the Fund can be expected to return less than 200% of the performance of the Underlying Stock and those shaded green (or light gray) represent those scenarios where the Fund can be expected to return more than 200% of the performance of the Underlying Stock. The Fund’s actual returns may be significantly better or worse than the returns shown below as a result of any of the factors discussed above or in “Tracking Error Risk” below.
The Underlying Stock’s annualized historical volatility rate from September 15, 2020 (Underlying Stock’s IPO date) to August 31, 2025, was 80.9%. During the period observed the Underlying Stock’s highest volatility rate over a 12-month period was 128.9% and volatility for a shorter period of time may have been substantially higher. The Underlying Stock’s annualized performance for the period considered August 31, 2025, was 14.9%. Historical volatility and performance are not indications of what the Underlying Stock volatility and performance will be in the future. The volatility of instruments that reflect the value of the Underlying Stock, such as swaps, may differ from the volatility of the Underlying Stock.

| Prospectus [Line Items] | ||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||
| Risk [Text Block] | Correlation Risk: A number of factors may affect the Fund’s ability to achieve a high degree of correlation with Underlying Stock, and there is no guarantee that the Fund will achieve a high degree of correlation. Failure to achieve a high degree of correlation may prevent the Fund from achieving its investment objective, and the percentage change of the Fund’s NAV each day may differ, perhaps significantly in amount, and possibly even direction, from 150% of the percentage change of Underlying Stock on such day.
In order to achieve a high degree of correlation with Underlying Stock, the Fund seeks to rebalance its portfolio daily to keep exposure consistent with its investment objective. Being materially under- or overexposed to Underlying Stock may prevent the Fund from achieving a high degree of correlation with Underlying Stock and may expose the Fund to greater leverage risk. Market disruptions or closure, regulatory restrictions, market volatility, illiquidity in the markets for the financial instruments in which the Fund invests, and other factors will adversely affect the Fund’s ability to adjust exposure to requisite levels. The target amount of portfolio exposure is impacted dynamically by Underlying Stock’s movements, including intraday movements. Because of this, it is unlikely that the Fund will have perfect 150% exposure during the day or at the end of each day and the likelihood of being materially under- or overexposed is higher on days when Underlying Stock is volatile, particularly when Underlying Stock is volatile at or near the close of the trading day.
A number of other factors may also adversely affect the Fund’s correlation with Underlying Stock, including fees, expenses, transaction costs, financing costs associated with the use of derivatives, income items, valuation methodology, accounting standards and disruptions or illiquidity in the markets for the securities or financial instruments in which the Fund invests. The Fund may take or refrain from taking positions in order to improve tax efficiency, comply with regulatory restrictions, or for other reasons, each of which may negatively affect the Fund’s correlation with Underlying Stock. The Fund may also be subject to large movements of assets into and out of the Fund, potentially resulting in the Fund being under- or overexposed to Underlying Stock. Additionally, the Fund’s underlying investments and/or reference assets may trade on markets that may not be open on the same day as the Fund, which may cause a difference between the changes in the daily performance of the Fund and changes in the performance of Underlying Stock. Any of these factors could decrease correlation between the performance of the Fund and Underlying Stock and may hinder the Fund’s ability to meet its daily investment objective on or around that day.

| Prospectus [Line Items] | ||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||
| 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 Stock 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 Underlying Stock, 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 Underlying Stock declines more than 50%. Leverage will also have the effect of magnifying any differences in the Fund performance’s correlation with the Underlying Stock.
Due to the limited availability of necessary investments or financial instruments, the Fund could, among other things, as a defensive measure, limit or suspend creations or redemptions of Creation Units until the adviser determines that the requisite exposure to the Underlying Stock is obtainable. During the period that creation or redemptions are affected, the Fund’s shares could trade at a significant premium or discount to their net asset value, or the bid-ask spread of the Fund’s shares could widen significantly. In the case of a period during which creations are suspended, the Fund could experience significant redemptions, which may cause the Fund to sell portfolio securities at unfavorable prices and increased transaction and other costs and make greater taxable distributions to shareholders of the Fund.

| Risk [Text Block] | Derivatives Risk: The use of derivative instruments involves risks different from, or possibly greater than, the risks associated with investing directly in securities and other traditional investments. These risks include (i) the risk that the counterparty to a derivative transaction may not fulfill its contractual obligations; (ii) risk of mispricing or improper valuation; and (iii) the risk that changes in the value of the derivative may not correlate perfectly with the underlying asset, rate or index. Derivative prices are highly volatile and may fluctuate substantially during a short period of time. Such prices are influenced by numerous factors that affect the markets, including, but not limited to: changing supply and demand relationships; government programs and policies; national and international political and economic events, changes in interest rates, inflation and deflation and changes in supply and demand relationships. Trading derivative instruments involves risks different from, or possibly greater than, the risks associated with investing directly in securities.

| Risk [Text Block] | Exchange Traded Fund Structure Risk: The Fund is structured as an exchange traded fund and as a result is subject to special risks, including:
The Fund will be subject to regulatory constraints relating to the 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 leverage performance for the Fund.

| 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] | Market and Geopolitical Risk: The increasing interconnectivity between global economies and financial markets increases the likelihood that events or conditions in one region or financial market may adversely impact issuers in a different country, region or financial market. Securities in the Fund’s portfolio may underperform due to inflation (or expectations for inflation), interest rates, global demand for particular products or resources, natural disasters, pandemics, epidemics, terrorism, regulatory events and governmental or quasi-governmental actions. The occurrence of global events similar to those in recent years, such as terrorist attacks around the world, natural disasters, social and political discord or debt crises and downgrades, among others, may result in market volatility and may have long term effects on both the U.S. and global financial markets. It is difficult to predict when similar events affecting the U.S. or global financial markets may occur, the effects that such events may have and the duration of those effects.

| Prospectus [Line Items] | ||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||
| Risk [Text Block] | Options Contracts Risk: The use of options contracts involves investment strategies and risks different from those associated with ordinary portfolio securities transactions. The prices of options are volatile and are influenced by, among other things, actual and anticipated changes in the value of the underlying instrument, including the anticipated volatility, which are affected by fiscal and monetary policies and by national and international political, changes in the actual or implied volatility or the reference asset, the time remaining until the expiration of the option contract and economic events. For the Fund, in particular, the value of the options contracts in which it invests is substantially influenced by the value of the Underlying Stock. The Fund may experience substantial downside from specific option positions and certain option positions held by the Fund may expire worthless. As an option approaches its expiration date, its value typically increasingly moves with the value of the underlying instrument. However, prior to such a date, the value of an option generally does not increase or decrease at the same rate at the underlying instrument. There may at times be an imperfect correlation between the movement in values of 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. Furthermore, when the Fund seeks to trade out of positions, especially near expiration, there is an added risk that the Fund may be required to allocate resources unexpectedly to fulfill these obligations. This potential exposure to physical settlement can significantly impact the Fund’s liquidity and market exposure, particularly in volatile market conditions. If the Fund sells non-cash settled options contracts, it would be obligated to receive shares of the Underlying Stock when the option is exercised. Consequently, there is a risk that the Fund may have to physically acquire the Underlying Stock shares at the strike price, which could result in the Fund holding the Underlying Stock, and an asset that has declined in value. The level of exposure obtained through option contracts should at most be equal to the Fund’s Daily Leverage Factor times the Fund’s net asset value.

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

| Risk [Text Block] | Trading Halt Risk: Although the Underlying Stock’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 Stock’s shares is expected, in turn, to result in a halt in the trading in the Fund’s shares. Trading in the Underlying Stock’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 Underling Stock’s and/or Fund’s shares inadvisable. In addition, trading in Underlying Stock’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] | Tracking Error Risk: Tracking error is the divergence of the Fund’s performance from that of its investment objective which aims to replicate 2 times the daily percentage change of the Underlying Stock. The performance of the Fund may diverge from that of its investment objective 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 Stock 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 objective as a result of market restrictions or other legal reasons, including regulatory limits or other restrictions on securities that may be purchased by the Adviser and its affiliates.

| Risk [Text Block] | Tax Risk: 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, particularly because the Fund’s investment objective focuses on the performance of the stock of a single issuer. 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] | Underlying Stock Risk: The performance of the Underlying Stock, and consequently the Fund’s performance, is subject to the risks of the industrial machinery industry. Availability and prices of raw materials, components, products and services from third-party suppliers, and such suppliers’ ability to timely deliver the quantities and quality required at reasonable prices could have a material adverse effect on our company, its prospects and financial performance. Worldwide economic conditions could have an effect on the demand for our company’s services and products and could result in declining revenue and earnings. General economic declines or a softening of the economy make it more likely that our company may experience difficulties collecting accounts receivable, sales and demand for our company’s products may decrease, and our company’s operating results may be adversely affected. The Fund’s daily returns may be affected by many factors but will depend on the performance and volatility of the Underlying Stock.

| Prospectus [Line Items] | ||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||
| Risk [Text Block] | Effects of Compounding and Market Volatility Risk: The Fund aims to replicate the daily leverage returns of the Underlying Stock 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 Underlying Stock’s performance, before fees and expenses. Compounding affects all investments but has a more significant impact on funds that aims to replicate daily leverage returns. For a Fund aiming to replicate 2 times the daily performance of an Underlying Stock, if adverse daily performance of the Underlying Stock 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 the favorable daily performance of the Underlying Stock 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 pronounced as the Underlying Stock 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 Stock during the shareholder’s holding period of an investment in the Fund.
The chart below provides examples of how Underlying Stock volatility could affect the Fund’s performance. Fund performance for periods greater than one single day can be estimated given any set of assumptions for the following factors: a) Underlying Stock volatility; b) Underlying Stock’s performance; c) period of time; d) financing rates associated with leveraged exposure; e) other Fund expenses; and f) the Underlying Stock’s dividends. The chart below illustrates the impact of two principal factors – Underlying Stock volatility and performance – on Fund performance. The chart shows estimated Fund returns for a number of combinations of Underlying Stock volatility and performance over a one-year period. Performance shown in the chart assumes that (i) there were no Fund expenses; and (ii) borrowing rates (needed to obtain a leveraged long exposure) of 0%. If Fund expenses and/or actual borrowing/lending rates were reflected, the estimated returns would be lower than those shown. Particularly during periods of higher Underlying Stock volatility, compounding will cause results for periods longer than a trading day to vary from the performance of the Underlying Stock.
As shown in the chart below, the Fund would be expected to lose 6.0% if the Underlying Stock provided no return over a one-year period during which the Underlying Stock experienced annualized volatility of 25%. At higher ranges of volatility, there is a chance of a significant loss of value in the Fund, even if the Underlying Stock return is flat.
For instance, if the Underlying Stock’s annualized volatility is 100%, the Fund would be expected to lose 63.3% of its value, even if the cumulative Underlying Stock’s return for the year was 0%. Areas shaded red (or dark gray) represent those scenarios where the Fund can be expected to return less than 200% of the performance of the Underlying Stock and those shaded green (or light gray) represent those scenarios where the Fund can be expected to return more than 200% of the performance of the Underlying Stock. The Fund’s actual returns may be significantly better or worse than the returns shown below as a result of any of the factors discussed above or in “Tracking Error Risk” below.
The Underlying Stock’s annualized historical volatility rate for the five-year period ended August 31, 2025, was 58.9%. During the five-year period observed the Underlying Stock’s highest volatility rate over a 12-month period was 68.5% and volatility for a shorter period of time may have been substantially higher. The Underlying Stock’s annualized performance for the five-year period ended August 31, 2025, was 50.8%. Historical volatility and performance are not indications of what the Underlying Stock volatility and performance will be in the future. The volatility of instruments that reflect the value of the Underlying Stock, such as swaps, may differ from the volatility of the Underlying Stock.

| Risk [Text Block] | Correlation Risk: A number of factors may affect the Fund’s ability to achieve a high degree of correlation with Underlying Stock, and there is no guarantee that the Fund will achieve a high degree of correlation. Failure to achieve a high degree of correlation may prevent the Fund from achieving its investment objective, and the percentage change of the Fund’s NAV each day may differ, perhaps significantly in amount, and possibly even direction, from 200% of the percentage change of Underlying Stock on such day.
In order to achieve a high degree of correlation with Underlying Stock, the Fund seeks to rebalance its portfolio daily to keep exposure consistent with its investment objective. Being materially under- or overexposed to Underlying Stock may prevent the Fund from achieving a high degree of correlation with Underlying Stock and may expose the Fund to greater leverage risk. Market disruptions or closure, regulatory restrictions, market volatility, illiquidity in the markets for the financial instruments in which the Fund invests, and other factors will adversely affect the Fund’s ability to adjust exposure to requisite levels. The target amount of portfolio exposure is impacted dynamically by Underlying Stock’s movements, including intraday movements. Because of this, it is unlikely that the Fund will have perfect 200% exposure during the day or at the end of each day and the likelihood of being materially under- or overexposed is higher on days when Underlying Stock is volatile, particularly when Underlying Stock is volatile at or near the close of the trading day.
A number of other factors may also adversely affect the Fund’s correlation with Underlying Stock, including fees, expenses, transaction costs, financing costs associated with the use of derivatives, income items, valuation methodology, accounting standards and disruptions or illiquidity in the markets for the securities or financial instruments in which the Fund invests. The Fund may take or refrain from taking positions in order to improve tax efficiency, comply with regulatory restrictions, or for other reasons, each of which may negatively affect the Fund’s correlation with Underlying Stock. The Fund may also be subject to large movements of assets into and out of the Fund, potentially resulting in the Fund being under- or overexposed to Underlying Stock. Additionally, the Fund’s underlying investments and/or reference assets may trade on markets that may not be open on the same day as the Fund, which may cause a difference between the changes in the daily performance of the Fund and changes in the performance of Underlying Stock. Any of these factors could decrease correlation between the performance of the Fund and Underlying Stock and may hinder the Fund’s ability to meet its daily investment objective on or around that day.

| 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 Stock 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 Underlying Stock, 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 Underlying Stock declines more than 50%. Leverage will also have the effect of magnifying any differences in the Fund performance’s correlation with the Underlying Stock.
Due to the limited availability of necessary investments or financial instruments, the Fund could, among other things, as a defensive measure, limit or suspend creations or redemptions of Creation Units until the adviser determines that the requisite exposure to the underlying Stock is obtainable. During the period that creation or redemptions are affected, the Fund’s shares could trade at a significant premium or discount to their net asset value, or the bid-ask spread of the Fund’s shares could widen significantly. In the case of a period during which creations are suspended, the Fund could experience significant redemptions, which may cause the Fund to sell portfolio securities at unfavorable prices and increased transaction and other costs and make greater taxable distributions to shareholders of the Fund.

| Risk [Text Block] | Derivatives Risk: The use of derivative instruments involves risks different from, or possibly greater than, the risks associated with investing directly in securities and other traditional investments. These risks include (i) the risk that the counterparty to a derivative transaction may not fulfill its contractual obligations; (ii) risk of mispricing or improper valuation; and (iii) the risk that changes in the value of the derivative may not correlate perfectly with the underlying asset, rate or index. Derivative prices are highly volatile and may fluctuate substantially during a short period of time. Such prices are influenced by numerous factors that affect the markets, including, but not limited to: changing supply and demand relationships; government programs and policies; national and international political and economic events, changes in interest rates, inflation and deflation and changes in supply and demand relationships. Trading derivative instruments involves risks different from, or possibly greater than, the risks associated with investing directly in securities.

| Risk [Text Block] | Exchange Traded Fund Structure Risk: The Fund is structured as an exchange traded fund and as a result is subject to special risks, including:
The Fund will be subject to regulatory constraints relating to the 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 performance for the Fund.

| 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] | Market and Geopolitical Risk: The increasing interconnectivity between global economies and financial markets increases the likelihood that events or conditions in one region or financial market may adversely impact issuers in a different country, region or financial market. Securities in the Fund’s portfolio may underperform due to inflation (or expectations for inflation), interest rates, global demand for particular products or resources, natural disasters, pandemics, epidemics, terrorism, regulatory events and governmental or quasi-governmental actions. The occurrence of global events similar to those in recent years, such as terrorist attacks around the world, natural disasters, social and political discord or debt crises and downgrades, among others, may result in market volatility and may have long term effects on both the U.S. and global financial markets. It is difficult to predict when similar events affecting the U.S. or global financial markets may occur, the effects that such events may have and the duration of those effects.

| Prospectus [Line Items] | ||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||
| Risk [Text Block] | Options Contracts Risk: The use of options contracts involves investment strategies and risks different from those associated with ordinary portfolio securities transactions. The prices of options are volatile and are influenced by, among other things, actual and anticipated changes in the value of the underlying instrument, including the anticipated volatility, which are affected by fiscal and monetary policies and by national and international political, changes in the actual or implied volatility or the reference asset, the time remaining until the expiration of the option contract and economic events. For the Fund, in particular, the value of the options contracts in which it invests is substantially influenced by the value of the Underlying Stock. The Fund may experience substantial downside from specific option positions and certain option positions held by the Fund may expire worthless. As an option approaches its expiration date, its value typically increasingly moves with the value of the underlying instrument. However, prior to such a date, the value of an option generally does not increase or decrease at the same rate at the underlying instrument. There may at times be an imperfect correlation between the movement in values of 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. Furthermore, when the Fund seeks to trade out of positions, especially near expiration, there is an added risk that the Fund may be required to allocate resources unexpectedly to fulfill these obligations. This potential exposure to physical settlement can significantly impact the Fund’s liquidity and market exposure, particularly in volatile market conditions. If the Fund sells non-cash settled options contracts, it would be obligated to receive shares of the Underlying Stock when the option is exercised. Consequently, there is a risk that the Fund may have to physically acquire the Underlying Stock shares at the strike price, which could result in the Fund holding the Underlying Stock, and an asset that has declined in value. The level of exposure obtained through option contracts should at most be equal to the Fund’s Daily Leverage Factor times the Fund’s net asset value.

| 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 Stock that is significantly greater or less than its stated multiple. As a result, the Fund may be more exposed to leverage risk than if it had been properly rebalanced and may not achieve its investment objective.

| Risk [Text Block] | Trading Halt Risk: Although the Underlying Stock’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 Stock’s shares is expected, in turn, to result in a halt in the trading in the Fund’s shares. Trading in the Underlying Stock’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 Underling Stock’s and/or Fund’s shares inadvisable. In addition, trading in Underlying Stock’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] | Tracking Error Risk: Tracking error is the divergence of the Fund’s performance from that of its investment objective which aims to replicate 2 times the daily percentage change of the Underlying Stock. The performance of the Fund may diverge from that of its investment objective 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 Stock 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 as a result of market restrictions or other legal reasons, including regulatory limits or other restrictions on securities that may be purchased by the Adviser and its affiliates.

| Risk [Text Block] | Tax Risk: 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, particularly because the Fund’s investment objective focuses on the performance of the stock of a single issuer. 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.
