| Risk [Text Block] | Autocallable Index and Payoff Structure Risks. The Autocallable Index is not an actual portfolio of securities. The Autocallable Index is a model that simulates how a group of autocallable instruments might perform. The Autocallable Index uses rules and assumptions to estimate coupon payments, early redemptions, reinvestment, and maturity outcomes. Although the Autocallable Index is designed to reflect prevailing market conditions and the performance of relevant market measures, its performance is hypothetical and based on assumptions that may differ from the terms, pricing, liquidity, and performance of actual autocallable investments available in the market. The Autocallable Index depends on inputs such as barrier levels, observation dates, reinvestment timing, and the performance of the Underlying Reference Index, and the Autocallable Index may perform differently than expected. Errors in the Autocallable Index’s model, data, or calculations, or changes to the Autocallable Index methodology, could negatively affect the Autocallable Index and the Fund.
The Fund’s returns are largely driven by the features of autocallable instruments reflected in the Autocallable Index. These features include conditional income payments, early redemption (or “autocall”) provisions, and the risk of reduced principal at maturity. Expected distributions of the Fund are based in part on modeled coupon payments that are only assumed to be paid if the Underlying Reference Index meets specified conditions on certain dates. If those conditions are not met, no coupon is assumed to be paid, which may result in lower, uneven, or no distributions. Poor performance, high volatility, or extended declines in the Underlying Reference Index increase the likelihood that these conditions will not be met. Early redemption features may limit the Fund’s participation in additional coupon payments and may require the Autocallable Index to reinvest in new autocallable instruments with less favorable terms or lower expected coupons. If an autocallable is not redeemed prior to maturity and the Underlying Reference Index is below a set level at maturity, the Autocallable Index assumes a reduction in principal, and the Fund could experience significant losses.

| Prospectus [Line Items] | ||||
| Risk [Text Block] | Underlying Reference Index Risk. The Fund’s performance depends heavily on the Nasdaq-100 Futures 35% Volatility Trend 6% Decrement™ Index (the “Underlying Reference Index”). The Underlying Reference Index provides exposure through futures contracts rather than directly holding the stocks in the Nasdaq-100 Index®, and returns of those futures may differ from the returns of those stocks. The Underlying Reference Index adjusts its exposure to equities in an effort to maintain a target level of volatility. During volatile periods, the Underlying Reference Index may reduce exposure, which could cause the Autocallable Index and the Fund to miss market recoveries or sustained gains.
The Underlying Reference Index may adjust its exposure multiple times during the day based on short-term market movements. This can increase the risk of poor timing and may reduce returns in unstable or rapidly changing markets. The Underlying Reference Index also includes a trend-following feature, which may perform poorly when markets move sideways or reverse direction quickly. In addition, the Underlying Reference Index applies a fixed annual reduction (“decrement”) and reflects assumed costs, which lower the level of the Underlying Reference Index over time regardless of market performance. The Underlying Reference Index’s results depend on the path of market movements, meaning that the timing and volatility of changes can significantly affect returns, even if the Nasdaq-100 Index® ends a period higher. Like the Autocallable Index, the Underlying Reference Index relies on models and data, and errors or changes in the Underlying Reference Index methodology could negatively affect the Autocallable Index and the Fund.

| Defiance Nasdaq 100 Autocallable Income ETF | Derivatives Risks [Member] | ||||
| Prospectus [Line Items] | ||||
| Risk [Text Block] | Derivatives Risks. Derivatives are financial instruments that derive value from the underlying reference asset or assets, such as stocks, bonds, or funds (including ETFs), interest rates or indexes. The Fund’s investments in derivatives may pose risks in addition to, and greater than, those associated with directly investing in securities or other ordinary investments, including risk related to the market, imperfect correlation with underlying investments or the Fund’s other portfolio holdings, higher price volatility, lack of availability, counterparty risk, liquidity, valuation and legal restrictions. The use of derivatives is a highly specialized activity that involves investment techniques and risks different from those associated with ordinary portfolio securities transactions. The use of derivatives may result in larger losses or smaller gains than directly investing in securities. When the Fund uses derivatives, there may be an imperfect correlation between the value of the underlying reference asset and the derivative, which may prevent the Fund from achieving its investment objective. Because derivatives often require only a limited initial investment, the use of derivatives may expose the Fund to losses in excess of those amounts initially invested. In addition, the Fund’s investments in derivatives are subject to the following risks:
|
|||
| Defiance Nasdaq 100 Autocallable Income ETF | Swap Agreements [Member] | ||||
| Prospectus [Line Items] | ||||
| Risk [Text Block] |
The swap agreements in which the Fund invests are generally traded in the over-the-counter market, which generally has less transparency than exchange-traded derivative instruments. In a standard swap transaction, two parties agree to exchange the return (or differentials in rates of return) earned or realized on particular predetermined reference assets, securities, or instruments. The gross return to be exchanged or “swapped” between the parties is calculated based on a notional amount or the return on or change in value of a particular dollar amount invested in the reference asset.
If the Underlying Security experiences a significant price movement that causes a material change in the Fund’s net assets, the terms of a swap agreement between the Fund and its counterparty may permit the counterparty to close out the swap transaction with the Fund. In that event, the Fund may be unable to enter into another swap agreement or invest in other derivatives to maintain exposure consistent with its investment objective. This may temporarily reduce the Fund’s ability to maintain its intended level of synthetic exposure until replacement transactions can be established.
Certain of the swap agreements entered into by the Fund may be unfunded total return swaps, pursuant to which the Fund does not make an initial investment of the full notional amount of the swap. As a result, the Fund is exposed to the risk that its counterparty will be unable to meet its obligations under the swap agreement, and the Fund’s exposure to a counterparty generally equals the net amount owed to the Fund based on the daily change in value of the reference asset. In the event of a counterparty default or insolvency, the Fund may incur losses in excess of the collateral, if any, posted by the counterparty, and the timing and amount of any recovery may be uncertain. In addition, the use of unfunded swap agreements may create economic leverage for the Fund, which may magnify gains and losses and increase the volatility of the Fund’s returns.
|
|||
| Defiance Nasdaq 100 Autocallable Income ETF | Counterparty Risk [Member] | ||||
| Prospectus [Line Items] | ||||
| Risk [Text Block] | Counterparty Risk. The Fund is subject to counterparty risk by virtue of its investments in swap agreements. Transactions in some types of derivatives, including certain swap agreements, are required to be centrally cleared (“cleared derivatives”). In a transaction involving cleared derivatives, the Fund’s counterparty is a clearing house rather than a bank or broker. Since the Fund is not a member of clearing houses and only members of a clearing house (“clearing members”) can participate directly in the clearing house, the Fund will hold cleared derivatives through accounts at clearing members. In cleared derivatives positions, the Fund will make payments (including margin payments) to and receive payments from a clearing house through its accounts at clearing members. Customer collateral held at a clearing organization in connection with cleared derivatives is held in an omnibus account and, although such collateral is legally segregated by customer, it is operationally commingled. As a result, in the event of a clearing member’s bankruptcy, the Fund may be limited to recovering only a pro rata share of the assets segregated on behalf of the clearing member’s customers for the relevant account class. In addition, although clearing members guarantee performance of their clients’ obligations to the clearing house, there is a risk that the assets of the Fund might not be fully protected in the event of a clearing member’s insolvency. The Fund is also subject to the risk that a limited number of clearing members are willing to transact on the Fund’s behalf, which heightens the risks associated with a clearing member’s default. If a clearing member defaults, the Fund could lose some or all of the benefits of a transaction entered into by the Fund. If the Fund cannot find a clearing member to transact with on the Fund’s behalf, the Fund may be unable to effectively implement its investment strategy.
|
|||
| Defiance Nasdaq 100 Autocallable Income ETF | Distribution Risk [Member] | ||||
| Prospectus [Line Items] | ||||
| Risk [Text Block] | Distribution Risk. As part of the Fund’s investment objective, the Fund seeks to provide current income monthly. There is no assurance that the Fund will make more than one, or any, distribution in a given month. If the Fund does make distributions, the amounts of such distributions will likely vary greatly from one distribution to the next.

| Defiance Nasdaq 100 Autocallable Income ETF | Concentration Risk [Member] | ||||
| Prospectus [Line Items] | ||||
| Risk [Text Block] | Concentration Risk. The Fund’s investment exposure will be concentrated in (or substantially exposed to) the same industry or group of industries assigned to the Underlying Reference Index. As a result, the Fund may be more susceptible to loss due to adverse occurrences that affect the price of such industries more than the market as a whole.

| Defiance Nasdaq 100 Autocallable Income ETF | Authorized Participants, Market Makers, and Liquidity Providers Concentration Risk [Member] | ||||
| Prospectus [Line Items] | ||||
| Risk [Text Block] | Authorized Participants, Market Makers, and Liquidity Providers Concentration Risk. The Fund has a limited number of financial institutions that are authorized to purchase and redeem Shares directly from the Fund (known as “Authorized Participants” or “APs”). In addition, there may be a limited number of market makers and/or liquidity providers in the marketplace. To the extent either of the following events occur, Shares may trade at a material discount to NAV and possibly face delisting: (i) APs exit the business or otherwise become unable to process creation and/or redemption orders and no other APs step forward to perform these services; or (ii) market makers and/or liquidity providers exit the business or significantly reduce their business activities and no other entities step forward to perform their functions.
|
|||
| Defiance Nasdaq 100 Autocallable Income ETF | Cash Redemption Risk [Member] | ||||
| Prospectus [Line Items] | ||||
| Risk [Text Block] | Cash Redemption Risk. The Fund’s investment strategy may require it to redeem Shares for cash or to otherwise include cash as part of its redemption proceeds. For example, the Fund may not be able to redeem in-kind certain securities held by the Fund (e.g., derivative instruments). In such a case, the Fund may be required to sell or unwind portfolio investments to obtain the cash needed to distribute redemption proceeds. This may cause the Fund to recognize a capital gain that it might not have recognized if it had made a redemption in-kind. As a result, the Fund may pay out higher annual capital gain distributions than if the in-kind redemption process was used. By paying out higher annual capital gain distributions, investors may be subjected to increased capital gains taxes. Additionally, there may be brokerage costs or taxable gains or losses that may be imposed on the Fund in connection with a cash redemption that may not have occurred if the Fund had made a redemption in-kind. These costs could decrease the value of the Fund to the extent they are not offset by a transaction fee payable by an AP.

| Prospectus [Line Items] | ||||
| Risk [Text Block] | Trading. Although Shares are listed on a national securities exchange, such as Cboe BZX Exchange (the “Exchange”), and may be traded on U.S. exchanges other than the Exchange, there can be no assurance that an active trading market for the Shares will develop or be maintained or that the Shares will trade with any volume, or at all, on any stock exchange. In stressed market conditions, the liquidity of Shares may begin to mirror the liquidity of the Fund’s underlying portfolio holdings, which can be significantly less liquid than Shares. Shares trade on the Exchange at market price that may be below, at or above the Fund’s NAV. Trading in Shares on the Exchange may be halted due to market conditions or for reasons that, in the view of the Exchange, make trading in Shares inadvisable. In addition, trading in Shares on the Exchange is subject to trading halts caused by extraordinary market volatility pursuant to the Exchange “circuit breaker” rules. There can be no assurance that the requirements of the Exchange necessary to maintain the listing of the Fund will continue to be met or will remain unchanged. As a result, the Fund could be adversely affected and be unable to implement its investment strategies in the event of an unscheduled closing.

|||
| Defiance Nasdaq 100 Autocallable Income ETF | Economic and Market Risk [Member] | ||||
| Prospectus [Line Items] | ||||
| Risk [Text Block] | Economic and Market Risk. Economies and financial markets throughout the world are becoming increasingly interconnected, which increases the likelihood that events or conditions in one country or region will adversely impact markets or issuers in other countries or regions. Securities in the Fund’s portfolio may underperform in comparison to securities in the general financial markets, a particular financial market, or other asset classes, due to a number of factors, including inflation (or expectations for inflation), deflation (or expectations for deflation), interest rates, global demand for particular products or resources, market instability, financial system instability, debt crises and downgrades, embargoes, tariffs, sanctions and other trade barriers, regulatory events, other governmental trade or market control programs and related geopolitical events. In addition, the value of the Fund’s investments may be negatively affected by the occurrence of global events such as war, terrorism, environmental disasters, natural disasters or events, country instability, and infectious disease epidemics or pandemics. The imposition by the U.S. of tariffs on goods imported from foreign countries and reciprocal tariffs levied on U.S. goods by those countries also may lead to volatility and instability in domestic and foreign markets.
|
|||
| Defiance Nasdaq 100 Autocallable Income ETF | High Portfolio Turnover Risk [Member] | ||||
| Prospectus [Line Items] | ||||
| Risk [Text Block] | High Portfolio Turnover Risk. The Fund may actively and frequently trade all or a significant portion of the Fund’s holdings. A high portfolio turnover rate increases transaction costs, which may increase the Fund’s expenses. Frequent trading may also cause adverse tax consequences for investors in the Fund due to an increase in short-term capital gains.
|
|||
| Defiance Nasdaq 100 Autocallable Income ETF | Inflation Risk [Member] | ||||
| Prospectus [Line Items] | ||||
| Risk [Text Block] | Inflation Risk. Inflation risk is the risk that the value of assets or income from investments will be less in the future as inflation decreases the value of money. As inflation increases, the present value of the Fund’s assets and distributions, if any, may decline.
|
|||
| Defiance Nasdaq 100 Autocallable Income ETF | Management Risk [Member] | ||||
| Prospectus [Line Items] | ||||
| Risk [Text Block] | Management Risk. The Fund is actively managed and may not meet its investment objective based on the Adviser’s success or failure to implement investment strategies for the Fund.
|
|||
| Defiance Nasdaq 100 Autocallable Income ETF | Money Market Instrument Risk [Member] | ||||
| Prospectus [Line Items] | ||||
| Risk [Text Block] | Money Market Instrument Risk. The Fund may use a variety of money market instruments for cash management purposes, including money market funds, depositary accounts and repurchase agreements. Repurchase agreements are contracts in which a seller of securities agrees to buy the securities back at a specified time and price. Repurchase agreements may be subject to market and credit risk related to the collateral securing the repurchase agreement. Money market instruments, including money market funds, may lose money through fees or other means.
|
|||
| Defiance Nasdaq 100 Autocallable Income ETF | New Fund Risk [Member] | ||||
| Prospectus [Line Items] | ||||
| Risk [Text Block] | New Fund Risk. The Fund is a recently organized management investment company with no operating history. As a result, prospective investors do not have a track record or history on which to base their investment decisions.
|
|||
| Defiance Nasdaq 100 Autocallable Income ETF | Operational Risk [Member] | ||||
| Prospectus [Line Items] | ||||
| Risk [Text Block] | Operational Risk. The Fund is subject to risks arising from various operational factors, including, but not limited to, human error, processing and communication errors, errors of the Fund’s service providers, counterparties or other third-parties, failed or inadequate processes and technology or systems failures. The Fund relies on third parties for a range of services, including custody. Any delay or failure relating to engaging or maintaining such service providers may affect the Fund’s ability to meet its investment objective. Although the Fund and Adviser seek to reduce these operational risks through controls and procedures, there is no way to completely protect against such risks.
|
|||
| Defiance Nasdaq 100 Autocallable Income ETF | Tax Risk [Member] | ||||
| Prospectus [Line Items] | ||||
| Risk [Text Block] | Tax Risk. The Fund intends to elect and to qualify each year to be treated as a regulated investment company (a “RIC”) under Subchapter M of the Internal Revenue Code of 1986, as amended (“Code”). To qualify and maintain its status as a RIC, the Fund must derive at least 90% of its gross income each year from “qualifying income,” meet certain diversification tests at the end of each quarter and meet an annual distribution test. For purposes of the qualifying income requirement, the treatment of the swaps and other derivatives that provide exposure to the synthetic Autocallables is not entirely clear, and thus whether the income and gain therefrom is qualifying income is uncertain. If the Fund were to treat income or gain from particular instruments linked to the synthetic Autocallables as qualifying income, an adverse determination or future guidance by the Internal Revenue Service with respect to the treatment of income or gain from those investments may adversely affect the Fund’s ability to qualify as a RIC. For purposes of the diversification test, the identification of the issuer (or, in some cases, issuers) of a particular Fund investment can depend on the terms and conditions of that investment. In particular, there is no published Internal Revenue Service guidance or case law on how to determine the “issuer” of certain derivatives that the Fund will enter into. An adverse determination or future guidance by the Internal Revenue Service with respect to issuer identification for the Fund’s investments may adversely affect the Fund’s ability to qualify as a RIC. To comply with the asset diversification test applicable to a RIC, the Fund will attempt to ensure that the value of swap contracts on shares of a single issuer does not exceed 25% of the Fund’s value at the close of any quarter. For this purpose, it is likely that the Internal Revenue Service will consider the Index to be a single issuer. If the value of swap contracts on shares of a single issuer were to exceed 25% of the Fund’s total assets at the end of a tax quarter, the Fund, generally, has a grace period to cure such lack of compliance. If the Fund fails to timely cure, it may no longer be eligible to be treated as a RIC.
As a RIC, the Fund will not be subject to U.S. federal income tax on the portion of its net investment income and net capital gain that it distributes to shareholders, provided that it satisfies certain income, diversification and distribution requirements of the Code. If the Fund does not qualify as a RIC for any taxable year and certain relief provisions are not available, the Fund’s taxable income will be subject to tax at the Fund level and to a further tax at the shareholder level when such income is distributed.
The federal income tax treatment of the swaps and other derivatives may not be as favorable as a direct investment in an underlying asset and may adversely affect the timing, character and amount of income the Fund realizes from its investments. As a result, a larger portion of the Fund’s distributions may be treated as ordinary income rather than capital gains. In addition, certain derivatives are subject to mark-to-market or straddle provisions of the Code. If such provisions are applicable, there could be an increase (or decrease) in the amount of taxable dividends paid by the Fund.

| Defiance Nasdaq 100 Autocallable Income ETF | U.S. Government and U.S. Agency Obligations Risk [Member] | ||||
| Prospectus [Line Items] | ||||
| Risk [Text Block] | U.S. Government and U.S. Agency Obligations Risk. The Fund may invest in securities issued by the U.S. government or its agencies or instrumentalities. U.S. Government obligations include securities issued or guaranteed as to principal and interest by the U.S. Government, its agencies or instrumentalities, such as the U.S. Treasury. Payment of principal and interest on U.S. Government obligations may be backed by the full faith and credit of the United States or may be backed solely by the issuing or guaranteeing agency or instrumentality itself. In the latter case, the investor must look principally to the agency or instrumentality issuing or guaranteeing the obligation for ultimate repayment, which agency or instrumentality may be privately owned. There can be no assurance that the U.S. Government would provide financial support to its agencies or instrumentalities (including government-sponsored enterprises) where it is not obligated to do so.

| Defiance Nasdaq 100 Autocallable Income ETF | Risk Nondiversified Status [Member] | ||||
| Prospectus [Line Items] | ||||
| Risk [Text Block] | Non-Diversification Risk. Because the Fund is “non-diversified,” it may invest a greater percentage of its assets in the securities of a single issuer or a smaller number of issuers than if it was a diversified fund. As a result, a decline in the value of an investment in a single issuer or a smaller number of issuers could cause the Fund’s overall value to decline to a greater degree than if the Fund held a more diversified portfolio.

| Defiance Bitcoin Autocallable ETF | Autocallable Index and Payoff Structure Risks [Member] | ||||
| Prospectus [Line Items] | ||||
| Risk [Text Block] | Autocallable Index and Payoff Structure Risks. The Autocallable Index is theoretical and represents the performance of a model-based, synthetic portfolio of autocallable instruments rather than actual tradable securities. The Autocallable Index relies on rules, assumptions, and quantitative models to simulate coupon payments, early redemptions, reinvestment, and maturity outcomes, which may not reflect actual market conditions or the performance of real-world autocallable instruments. The Autocallable Index’s behavior depends on assumed parameters, including barrier levels, observation schedules, reinvestment timing, and the characteristics of the Underlying Reference Index, and may perform differently than expected. Errors in index design, calculation, data inputs, or assumptions, or changes to the Autocallable Index methodology, could adversely affect the Autocallable Index and, consequently, the Fund.
The Fund’s returns are largely driven by the features of autocallable instruments reflected in the Autocallable Index. These features include conditional income payments, early redemption (or “autocall”) provisions, and the risk of reduced principal at maturity. Expected distributions of the Fund are based in part on modeled coupon payments that are only assumed to be paid if the Underlying Reference Index meets specified conditions on certain dates. If those conditions are not met, no coupon is assumed to be paid, which may result in lower, uneven, or no distributions. Poor performance, high volatility, or extended declines in the Underlying Reference Index increase the likelihood that these conditions will not be met. Early redemption features may limit the Fund’s participation in additional coupon payments and may require the Autocallabe Index to reinvest in new autocallable instruments with less favorable terms or lower expected coupons. If an autocallable is not redeemed prior to maturity and the Underlying Reference Index is below a set level at maturity, the Autocallable Index assumes a reduction in principal, and the Fund could experience significant losses.

| Prospectus [Line Items] | ||||
| Risk [Text Block] | Underlying Reference Index Risk. The Fund’s performance is significantly dependent on the performance and characteristics of the Cboe Edge Bitcoin 35% Volatility Target 6% Decrement Index (the “Underlying Reference Index”). The Underlying Reference Index is rules-based and provides exposure to bitcoin through bitcoin futures contracts rather than direct investment in bitcoin, and the performance of bitcoin futures may diverge from the performance of spot bitcoin due to factors such as contango, backwardation, roll costs, liquidity constraints, and margin requirements. The Underlying Reference Index seeks to target a specified volatility level by increasing or decreasing its bitcoin futures exposure based on observed market volatility, which may cause the Underlying Reference Index to reduce exposure during periods of elevated volatility and miss subsequent price recoveries or sustained rallies. Bitcoin markets have historically exhibited significant volatility, which may result in frequent and substantial exposure adjustments. The Underlying Reference Index generally adjusts exposure daily based on realized volatility and other model-driven signals, which may increase market timing risk and reduce returns in choppy, rapidly reversing, or highly volatile markets. The Underlying Reference Index may also incorporate trend-based signals that may perform poorly in sideways or whipsaw markets and may cause exposure to be increased or decreased at disadvantageous times. In addition, the Underlying Reference Index applies a fixed annual decrement of 6% and reflects assumed trading, roll, and financing costs that reduce the index level over time regardless of market performance, creating a persistent drag on returns. The Underlying Reference Index’s performance is path dependent, meaning results may be materially affected by the sequence, magnitude, and volatility of bitcoin price movements, even if bitcoin prices increase over a given period. The Underlying Reference Index relies on quantitative models, rules, and data inputs, and errors in index design or calculation, disruptions in the bitcoin futures markets, or changes to index methodology could adversely affect the Underlying Reference Index and, consequently, the Fund.

| Risk [Text Block] | Derivatives Risks. Derivatives are financial instruments that derive value from the underlying reference asset or assets, such as stocks, bonds, or funds (including ETFs), interest rates or indexes. The Fund’s investments in derivatives may pose risks in addition to, and greater than, those associated with directly investing in securities or other ordinary investments, including risk related to the market, imperfect correlation with underlying investments or the Fund’s other portfolio holdings, higher price volatility, lack of availability, counterparty risk, liquidity, valuation and legal restrictions. The use of derivatives is a highly specialized activity that involves investment techniques and risks different from those associated with ordinary portfolio securities transactions. The use of derivatives may result in larger losses or smaller gains than directly investing in securities. When the Fund uses derivatives, there may be an imperfect correlation between the value of the underlying reference asset and the derivative, which may prevent the Fund from achieving its investment objective. Because derivatives often require only a limited initial investment, the use of derivatives may expose the Fund to losses in excess of those amounts initially invested. In addition, the Fund’s investments in derivatives are subject to the following risks:

The gross return to be exchanged or “swapped” between the parties is calculated based on a notional amount or the return on or change in value of a particular dollar amount invested in the reference asset.
If the Underlying Security experiences a significant price movement that causes a material change in the Fund’s net assets, the terms of a swap agreement between the Fund and its counterparty may permit the counterparty to close out the swap transaction with the Fund. In that event, the Fund may be unable to enter into another swap agreement or invest in other derivatives to maintain exposure consistent with its investment objective. This may temporarily reduce the Fund’s ability to maintain its intended level of synthetic exposure until replacement transactions can be established.
Certain of the swap agreements entered into by the Fund may be unfunded total return swaps, pursuant to which the Fund does not make an initial investment of the full notional amount of the swap. As a result, the Fund is exposed to the risk that its counterparty will be unable to meet its obligations under the swap agreement, and the Fund’s exposure to a counterparty generally equals the net amount owed to the Fund based on the daily change in value of the reference asset. In the event of a counterparty default or insolvency, the Fund may incur losses in excess of the collateral, if any, posted by the counterparty, and the timing and amount of any recovery may be uncertain. In addition, the use of unfunded swap agreements may create economic leverage for the Fund, which may magnify gains and losses and increase the volatility of the Fund’s returns.
|

| Defiance Bitcoin Autocallable ETF | Counterparty Risk [Member] | ||||
| Prospectus [Line Items] | ||||
| Risk [Text Block] | Counterparty Risk. The Fund is subject to counterparty risk by virtue of its investments in swap agreements. Transactions in some types of derivatives, including certain swap agreements, are required to be centrally cleared (“cleared derivatives”). In a transaction involving cleared derivatives, the Fund’s counterparty is a clearing house rather than a bank or broker. Since the Fund is not a member of clearing houses and only members of a clearing house (“clearing members”) can participate directly in the clearing house, the Fund will hold cleared derivatives through accounts at clearing members. In cleared derivatives positions, the Fund will make payments (including margin payments) to and receive payments from a clearing house through its accounts at clearing members. Customer collateral held at a clearing organization in connection with cleared derivatives is held in an omnibus account and, although such collateral is legally segregated by customer, it is operationally commingled. As a result, in the event of a clearing member’s bankruptcy, the Fund may be limited to recovering only a pro rata share of the assets segregated on behalf of the clearing member’s customers for the relevant account class. In addition, although clearing members guarantee performance of their clients’ obligations to the clearing house, there is a risk that the assets of the Fund might not be fully protected in the event of a clearing member’s insolvency. The Fund is also subject to the risk that a limited number of clearing members are willing to transact on the Fund’s behalf, which heightens the risks associated with a clearing member’s default. If a clearing member defaults, the Fund could lose some or all of the benefits of a transaction entered into by the Fund. If the Fund cannot find a clearing member to transact with on the Fund’s behalf, the Fund may be unable to effectively implement its investment strategy.

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

Although Shares are listed on a national securities exchange, such as Cboe BZX Exchange (the “Exchange”), and may be traded on U.S. exchanges other than the Exchange, there can be no assurance that an active trading market for the Shares will develop or be maintained or that the Shares will trade with any volume, or at all, on any stock exchange. In stressed market conditions, the liquidity of Shares may begin to mirror the liquidity of the Fund’s underlying portfolio holdings, which can be significantly less liquid than Shares. Shares trade on the Exchange at market price that may be below, at or above the Fund’s NAV. Trading in Shares on the Exchange may be halted due to market conditions or for reasons that, in the view of the Exchange, make trading in Shares inadvisable. In addition, trading in Shares on the Exchange is subject to trading halts caused by extraordinary market volatility pursuant to the Exchange “circuit breaker” rules. There can be no assurance that the requirements of the Exchange necessary to maintain the listing of the Fund will continue to be met or will remain unchanged.

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

|

| Defiance Bitcoin Autocallable ETF | Tax Risk [Member] | ||||
| Prospectus [Line Items] | ||||
| Risk [Text Block] | Tax Risk. The Fund intends to elect and to qualify each year to be treated as a regulated investment company (a “RIC”) under Subchapter M of the Internal Revenue Code of 1986, as amended (“Code”). To qualify and maintain its status as a RIC, the Fund must derive at least 90% of its gross income each year from “qualifying income,” meet certain diversification tests at the end of each quarter and meet an annual distribution test. For purposes of the qualifying income requirement, the treatment of the swaps and other derivatives that provide exposure to the synthetic Autocallables is not entirely clear, and thus whether the income and gain therefrom is qualifying income is uncertain. If the Fund were to treat income or gain from particular instruments linked to the synthetic Autocallables as qualifying income, an adverse determination or future guidance by the Internal Revenue Service with respect to the treatment of income or gain from those investments may adversely affect the Fund’s ability to qualify as a RIC. For purposes of the diversification test, the identification of the issuer (or, in some cases, issuers) of a particular Fund investment can depend on the terms and conditions of that investment. In particular, there is no published Internal Revenue Service guidance or case law on how to determine the “issuer” of certain derivatives that the Fund will enter into. An adverse determination or future guidance by the Internal Revenue Service with respect to issuer identification for the Fund’s investments may adversely affect the Fund’s ability to qualify as a RIC. To comply with the asset diversification test applicable to a RIC, the Fund will attempt to ensure that the value of swap contracts on shares of a single issuer does not exceed 25% of the Fund’s value at the close of any quarter. For this purpose, it is likely that the Internal Revenue Service will consider the Index to be a single issuer. If the value of swap contracts on shares of a single issuer were to exceed 25% of the Fund’s total assets at the end of a tax quarter, the Fund, generally, has a grace period to cure such lack of compliance. If the Fund fails to timely cure, it may no longer be eligible to be treated as a RIC.
As a RIC, the Fund will not be subject to U.S. federal income tax on the portion of its net investment income and net capital gain that it distributes to shareholders, provided that it satisfies certain income, diversification and distribution requirements of the Code. If the Fund does not qualify as a RIC for any taxable year and certain relief provisions are not available, the Fund’s taxable income will be subject to tax at the Fund level and to a further tax at the shareholder level when such income is distributed.
The federal income tax treatment of the swaps and other derivatives may not be as favorable as a direct investment in an underlying asset and may adversely affect the timing, character and amount of income the Fund realizes from its investments. As a result, a larger portion of the Fund’s distributions may be treated as ordinary income rather than capital gains. In addition, certain derivatives are subject to mark-to-market or straddle provisions of the Code. If such provisions are applicable, there could be an increase (or decrease) in the amount of taxable dividends paid by the Fund.

U.S. Government obligations include securities issued or guaranteed as to principal and interest by the U.S. Government, its agencies or instrumentalities, such as the U.S. Treasury. Payment of principal and interest on U.S. Government obligations may be backed by the full faith and credit of the United States or may be backed solely by the issuing or guaranteeing agency or instrumentality itself. In the latter case, the investor must look principally to the agency or instrumentality issuing or guaranteeing the obligation for ultimate repayment, which agency or instrumentality may be privately owned. There can be no assurance that the U.S. Government would provide financial support to its agencies or instrumentalities (including government-sponsored enterprises) where it is not obligated to do so.

| Defiance Bitcoin Autocallable ETF | IBIT Risk [Member] | ||||
| Prospectus [Line Items] | ||||
| Risk [Text Block] | IBIT Risk. The Fund does not invest directly in the iShares Bitcoin Trust (“IBIT”) but may have indirect exposure to IBIT through autocallable instruments linked to a reference index that obtains bitcoin-related exposure through IBIT. As a result, the Fund may be exposed to certain risks associated with IBIT even though it does not own IBIT shares. IBIT’s performance is driven primarily by the price of bitcoin, which is highly volatile and has experienced significant price swings over short periods of time. Bitcoin prices may be affected by market speculation, investor sentiment, regulatory developments, technological changes, cybersecurity events, macroeconomic conditions, interest rate movements, and changes in demand and supply in global bitcoin markets. Negative developments in the digital asset ecosystem, including exchange failures, fraud, or security breaches, could adversely affect bitcoin prices and the value of IBIT. IBIT’s net asset value depends on pricing sources for bitcoin and the proper functioning of digital asset trading platforms and custodial arrangements. Disruptions, manipulation concerns, technological failures, forks in the bitcoin blockchain, or changes to the bitcoin protocol could adversely affect IBIT’s valuation and market price. In addition, IBIT may trade at a premium or discount to its net asset value, particularly during periods of market stress or constrained liquidity. IBIT is concentrated solely in bitcoin and is therefore more volatile than diversified investment vehicles. Bitcoin is a relatively new asset with a limited performance history and is subject to unique risks, including regulatory uncertainty in the United States and abroad. Future regulatory actions, including restrictions on bitcoin trading, ownership, or mining, could negatively impact IBIT. IBIT is not affiliated with the Fund or its Adviser and is not registered under the 1940Act. Fund shareholders have no rights with respect to IBIT, including voting or distribution rights, and do not benefit from the investor protections applicable to registered investment companies. In addition, IBIT relies on third-party custodians to hold its bitcoin. Digital asset custody involves heightened risks, including potential loss due to hacking, theft, fraud, technological failure, or loss of private keys. Any operational disruption, cybersecurity incident, trading halt, or liquidity constraint affecting IBIT could negatively impact the value of the Fund’s indirect exposure.

| Risk [Text Block] | Cayman Subsidiary Risk. By investing in the Subsidiary, the Fund is indirectly exposed to the risks associated with the Subsidiary’s investments. The futures contracts and other investments held by the Subsidiary are subject to the same economic risks that apply to similar investments if held directly by the Fund. The Subsidiary is not registered under the 1940 Act, and, unless otherwise noted in this Prospectus, is not subject to all the investor protections of the 1940 Act. Changes in the laws of the United States and the Cayman Islands could result in the inability of the Fund and/or the Subsidiary to continue to operate as it does currently and could adversely affect the Fund. For example, the Cayman Islands does not currently impose any income, corporate or capital gains tax or withholding tax on the Subsidiary. If Cayman Islands law changes such that the Subsidiary must pay Cayman Islands taxes, Fund shareholders would likely suffer decreased investment returns. In addition, the Subsidiary is also subject to many of the risks to which the Fund is subject, such as tax risks, commodity related risks, and market and data risks. |

| Risk [Text Block] | Commodity Pool Regulatory Risk. The Fund’s strategies will cause it to be deemed to be a commodity pool, thereby subjecting the Fund to regulation under the CEA and CFTC rules. The Adviser is registered as a commodity pool operator (“CPO”), the Futures Trading Advisor is also registered as a CPO as well as a commodity trading advisor (“CTA’) and the Fund will be operated in accordance with applicable CFTC rules, as well as the regulatory scheme applicable to registered investment companies. Registration as a CPO or CTA imposes additional compliance obligations on the Adviser and Futures Trading Advisor, as applicable, and the Fund related to additional laws, regulations, and enforcement policies, which could increase compliance costs and may affect the operations and financial performance of the Fund. However, the Fund’s status as a commodity pool and the Adviser’s and Futures Trading Advisor’s registration as a CPO (and CTA, as applicable), are not expected to materially adversely affect the Fund’s ability to achieve its investment objective. The CFTC has not passed on the adequacy of this Prospectus.

| Defiance Gold Autocallable ETF | Autocallable Index and Payoff Structure Risks [Member] | ||||
| Prospectus [Line Items] | ||||
| Risk [Text Block] | Autocallable Index and Payoff Structure Risks. The Autocallable Index is theoretical and represents the performance of a model-based, synthetic portfolio of autocallable instruments rather than actual tradable securities. The Autocallable Index relies on rules, assumptions, and quantitative models to simulate coupon payments, early redemptions, reinvestment, and maturity outcomes, which may not reflect actual market conditions or the performance of real-world autocallable instruments. The Autocallable Index’s behavior depends on assumed parameters, including barrier levels, observation schedules, reinvestment timing, and the characteristics of the Underlying Reference Index, and may perform differently than expected. Errors in index design, calculation, data inputs, or assumptions, or changes to the Autocallable Index methodology, could adversely affect the Autocallable Index and, consequently, the Fund.
The Fund’s return characteristics are largely driven by the structural features of autocallable instruments reflected in the Autocallable Index, including contingent income payments, early redemption provisions, and contingent repayment of principal. Distributions are expected to be based in part on modelled coupon payments that are contingent on the Underlying Reference Index meeting specified performance thresholds on observation dates, and no coupon is assumed to be paid if those conditions are not met, which may result in reduced, irregular, or no distributions. Declines, heightened volatility, or prolonged drawdowns in the Underlying Reference Index increase the likelihood that coupon and autocall conditions will not be met. Early redemption features may limit the Fund’s participation in sustained or sharp increases in the Underlying Reference Index, causing the Fund to underperform traditional equity investments during strong market rallies. If an Autocallable is not redeemed prior to maturity and the Underlying Reference Index is below the applicable maturity barrier at maturity, the modelled principal repayment is reduced to reflect the negative performance of the Underlying Reference Index, and the Fund may experience significant losses, which could be substantial.
|
|||
| Defiance Gold Autocallable ETF | Underlying Reference Index Risk [Member] | ||||
| Prospectus [Line Items] | ||||
| Risk [Text Block] | Underlying Reference Index Risk. The Fund’s performance is significantly dependent on the performance and characteristics of the Cboe Edge Gold 35% Volatility Target 6% Decrement Index (the “Underlying Reference Index”). The Underlying Reference Index is rules-based and provides exposure to gold through gold futures contracts rather than direct investment in physical gold, and the performance of gold futures may diverge from the performance of spot gold prices due to factors such as contango, backwardation, roll yield, storage costs, liquidity conditions, and margin requirements. The Underlying Reference Index seeks to target a specified volatility level by increasing or decreasing its gold futures exposure based on observed market volatility, which may cause the Underlying Reference Index to reduce exposure during periods of heightened volatility and miss subsequent rebounds or sustained advances in gold prices. The Underlying Reference Index generally adjusts exposure daily based on realized volatility and other model-driven signals, which may increase market timing risk and reduce returns in choppy, rapidly reversing, or highly volatile markets. The Underlying Reference Index may also include trend-following components that may perform poorly in sideways or whipsaw markets and may increase or decrease exposure at unfavorable times. In addition, the Underlying Reference Index applies a fixed annual decrement of 6% and reflects assumed trading, roll, and financing costs that reduce the index level over time regardless of market performance, creating a persistent drag on returns. The Underlying Reference Index’s performance is path dependent, meaning results may be materially affected by the sequence and volatility of gold price movements, even if gold prices increase over a given period. The Underlying Reference Index relies on quantitative models, rules, and data inputs, and errors in index design or calculation, disruptions in the gold futures markets, or changes to index methodology could adversely affect the Underlying Reference Index and, consequently, the Fund.

| Defiance Gold Autocallable ETF | Derivatives Risks [Member] | ||||
| Prospectus [Line Items] | ||||
| Risk [Text Block] | Derivatives Risks. Derivatives are financial instruments that derive value from the underlying reference asset or assets, such as stocks, bonds, or funds (including ETFs), interest rates or indexes. The Fund’s investments in derivatives may pose risks in addition to, and greater than, those associated with directly investing in securities or other ordinary investments, including risk related to the market, imperfect correlation with underlying investments or the Fund’s other portfolio holdings, higher price volatility, lack of availability, counterparty risk, liquidity, valuation and legal restrictions. The use of derivatives is a highly specialized activity that involves investment techniques and risks different from those associated with ordinary portfolio securities transactions. The use of derivatives may result in larger losses or smaller gains than directly investing in securities. When the Fund uses derivatives, there may be an imperfect correlation between the value of the underlying reference asset and the derivative, which may prevent the Fund from achieving its investment objective. Because derivatives often require only a limited initial investment, the use of derivatives may expose the Fund to losses in excess of those amounts initially invested. In addition, the Fund’s investments in derivatives are subject to the following risks:
|
|||
| Defiance Gold Autocallable ETF | Swap Agreements [Member] | ||||
| Prospectus [Line Items] | ||||
| Risk [Text Block] |
The swap agreements in which the Fund invests are generally traded in the over-the-counter market, which generally has less transparency than exchange-traded derivative instruments. In a standard swap transaction, two parties agree to exchange the return (or differentials in rates of return) earned or realized on particular predetermined reference assets, securities, or instruments. The gross return to be exchanged or “swapped” between the parties is calculated based on a notional amount or the return on or change in value of a particular dollar amount invested in the reference asset.
If the Underlying Security experiences a significant price movement that causes a material change in the Fund’s net assets, the terms of a swap agreement between the Fund and its counterparty may permit the counterparty to close out the swap transaction with the Fund. In that event, the Fund may be unable to enter into another swap agreement or invest in other derivatives to maintain exposure consistent with its investment objective. This may temporarily reduce the Fund’s ability to maintain its intended level of synthetic exposure until replacement transactions can be established.
Certain of the swap agreements entered into by the Fund may be unfunded total return swaps, pursuant to which the Fund does not make an initial investment of the full notional amount of the swap. As a result, the Fund is exposed to the risk that its counterparty will be unable to meet its obligations under the swap agreement, and the Fund’s exposure to a counterparty generally equals the net amount owed to the Fund based on the daily change in value of the reference asset. In the event of a counterparty default or insolvency, the Fund may incur losses in excess of the collateral, if any, posted by the counterparty, and the timing and amount of any recovery may be uncertain. In addition, the use of unfunded swap agreements may create economic leverage for the Fund, which may magnify gains and losses and increase the volatility of the Fund’s returns.
|
|||
| Defiance Gold Autocallable ETF | Counterparty Risk [Member] | ||||
| Prospectus [Line Items] | ||||
| Risk [Text Block] | Counterparty Risk. The Fund is subject to counterparty risk by virtue of its investments in swap agreements. Transactions in some types of derivatives, including certain swap agreements, are required to be centrally cleared (“cleared derivatives”). In a transaction involving cleared derivatives, the Fund’s counterparty is a clearing house rather than a bank or broker. Since the Fund is not a member of clearing houses and only members of a clearing house (“clearing members”) can participate directly in the clearing house, the Fund will hold cleared derivatives through accounts at clearing members. In cleared derivatives positions, the Fund will make payments (including margin payments) to and receive payments from a clearing house through its accounts at clearing members. Customer collateral held at a clearing organization in connection with cleared derivatives is held in an omnibus account and, although such collateral is legally segregated by customer, it is operationally commingled. As a result, in the event of a clearing member’s bankruptcy, the Fund may be limited to recovering only a pro rata share of the assets segregated on behalf of the clearing member’s customers for the relevant account class. In addition, although clearing members guarantee performance of their clients’ obligations to the clearing house, there is a risk that the assets of the Fund might not be fully protected in the event of a clearing member’s insolvency. The Fund is also subject to the risk that a limited number of clearing members are willing to transact on the Fund’s behalf, which heightens the risks associated with a clearing member’s default. If a clearing member defaults, the Fund could lose some or all of the benefits of a transaction entered into by the Fund. If the Fund cannot find a clearing member to transact with on the Fund’s behalf, the Fund may be unable to effectively implement its investment strategy.

The Fund has a limited number of financial institutions that are authorized to purchase and redeem Shares directly from the Fund (known as “Authorized Participants” or “APs”). In addition, there may be a limited number of market makers and/or liquidity providers in the marketplace. To the extent either of the following events occur, Shares may trade at a material discount to NAV and possibly face delisting: (i) APs exit the business or otherwise become unable to process creation and/or redemption orders and no other APs step forward to perform these services; or (ii) market makers and/or liquidity providers exit the business or significantly reduce their business activities and no other entities step forward to perform their functions.
|
|||
| Defiance Gold Autocallable ETF | Cash Redemption Risk [Member] | ||||
| Prospectus [Line Items] | ||||
| Risk [Text Block] | Cash Redemption Risk. The Fund’s investment strategy may require it to redeem Shares for cash or to otherwise include cash as part of its redemption proceeds. For example, the Fund may not be able to redeem in-kind certain securities held by the Fund (e.g., derivative instruments). In such a case, the Fund may be required to sell or unwind portfolio investments to obtain the cash needed to distribute redemption proceeds. This may cause the Fund to recognize a capital gain that it might not have recognized if it had made a redemption in-kind. As a result, the Fund may pay out higher annual capital gain distributions than if the in-kind redemption process was used. By paying out higher annual capital gain distributions, investors may be subjected to increased capital gains taxes. Additionally, there may be brokerage costs or taxable gains or losses that may be imposed on the Fund in connection with a cash redemption that may not have occurred if the Fund had made a redemption in-kind. These costs could decrease the value of the Fund to the extent they are not offset by a transaction fee payable by an AP.

To qualify and maintain its status as a RIC, the Fund must derive at least 90% of its gross income each year from “qualifying income,” meet certain diversification tests at the end of each quarter and meet an annual distribution test. For purposes of the qualifying income requirement, the treatment of the swaps and other derivatives that provide exposure to the synthetic Autocallables is not entirely clear, and thus whether the income and gain therefrom is qualifying income is uncertain. If the Fund were to treat income or gain from particular instruments linked to the synthetic Autocallables as qualifying income, an adverse determination or future guidance by the Internal Revenue Service with respect to the treatment of income or gain from those investments may adversely affect the Fund’s ability to qualify as a RIC. For purposes of the diversification test, the identification of the issuer (or, in some cases, issuers) of a particular Fund investment can depend on the terms and conditions of that investment. In particular, there is no published Internal Revenue Service guidance or case law on how to determine the “issuer” of certain derivatives that the Fund will enter into. An adverse determination or future guidance by the Internal Revenue Service with respect to issuer identification for the Fund’s investments may adversely affect the Fund’s ability to qualify as a RIC. To comply with the asset diversification test applicable to a RIC, the Fund will attempt to ensure that the value of swap contracts on shares of a single issuer does not exceed 25% of the Fund’s value at the close of any quarter. For this purpose, it is likely that the Internal Revenue Service will consider the Index to be a single issuer. If the value of swap contracts on shares of a single issuer were to exceed 25% of the Fund’s total assets at the end of a tax quarter, the Fund, generally, has a grace period to cure such lack of compliance. If the Fund fails to timely cure, it may no longer be eligible to be treated as a RIC.
As a RIC, the Fund will not be subject to U.S. federal income tax on the portion of its net investment income and net capital gain that it distributes to shareholders, provided that it satisfies certain income, diversification and distribution requirements of the Code. If the Fund does not qualify as a RIC for any taxable year and certain relief provisions are not available, the Fund’s taxable income will be subject to tax at the Fund level and to a further tax at the shareholder level when such income is distributed.
The federal income tax treatment of the swaps and other derivatives may not be as favorable as a direct investment in an underlying asset and may adversely affect the timing, character and amount of income the Fund realizes from its investments. As a result, a larger portion of the Fund’s distributions may be treated as ordinary income rather than capital gains. In addition, certain derivatives are subject to mark-to-market or straddle provisions of the Code. If such provisions are applicable, there could be an increase (or decrease) in the amount of taxable dividends paid by the Fund.

The futures contracts and other investments held by the Subsidiary are subject to the same economic risks that apply to similar investments if held directly by the Fund. The Subsidiary is not registered under the 1940 Act, and, unless otherwise noted in this Prospectus, is not subject to all the investor protections of the 1940 Act. Changes in the laws of the United States and the Cayman Islands could result in the inability of the Fund and/or the Subsidiary to continue to operate as it does currently and could adversely affect the Fund. For example, the Cayman Islands does not currently impose any income, corporate or capital gains tax or withholding tax on the Subsidiary. If Cayman Islands law changes such that the Subsidiary must pay Cayman Islands taxes, Fund shareholders would likely suffer decreased investment returns. In addition, the Subsidiary is also subject to many of the risks to which the Fund is subject, such as tax risks, commodity related risks, and market and data risks.

| Prospectus [Line Items] | ||||
| Risk [Text Block] | GLD Risk. The Fund does not invest directly in GLD but may have indirect exposure to GLD through Underlying Reference Index, which obtains gold-related exposure through GLD. As a result, the Fund may be exposed to certain risks associated with GLD even though it does not own GLD shares. GLD’s performance is driven primarily by the price of gold, which can be highly volatile and may fluctuate rapidly based on global economic and political conditions, interest rates, inflation expectations, currency movements, central bank activity (including large-scale gold sales), geopolitical events, and changes in gold supply and demand. These factors may cause sudden declines in GLD’s market price and could adversely affect the value of the Fund’s investments. GLD is not affiliated with the Fund or the Adviser and is not involved in the offering of the Fund. GLD is not registered under the 1940 Act, and investors in the Fund do not receive the protections that statute provides with respect to registered investment companies. Fund shareholders have no rights with respect to GLD, including voting rights or rights to receive any dividends or other distributions. In addition, GLD is subject to risks related to the custody, safeguarding, and valuation of the gold it holds, including reliance on third-party custodians and subcustodians, potential losses or delays arising from theft, damage, or inaccessibility of gold, and limited or no insurance coverage. GLD’s valuation may depend on gold pricing benchmarks, and errors, disruptions, or changes to such benchmarks could adversely affect GLD’s value. Operational issues, trading disruptions, market liquidity constraints, or other events affecting GLD could also negatively impact the Fund’s indirect exposure to GLD.

| Defiance Silver Autocallable ETF | Autocallable Index and Payoff Structure Risks [Member] | ||||
| Prospectus [Line Items] | ||||
| Risk [Text Block] | Autocallable Index and Payoff Structure Risks. The Autocallable Index is theoretical and represents the performance of a model-based, synthetic portfolio of autocallable instruments rather than actual tradable securities. The Autocallable Index relies on rules, assumptions, and quantitative models to simulate coupon payments, early redemptions, reinvestment, and maturity outcomes, which may not reflect actual market conditions or the performance of real-world autocallable instruments. The Autocallable Index’s behavior depends on assumed parameters, including barrier levels, observation schedules, reinvestment timing, and the characteristics of the Underlying Reference Index, and may perform differently than expected. Errors in index design, calculation, data inputs, or assumptions, or changes to the Autocallable Index methodology, could adversely affect the Autocallable Index and, consequently, the Fund.
The Fund’s return characteristics are largely driven by the structural features of autocallable instruments reflected in the Autocallable Index, including contingent income payments, early redemption provisions, and contingent repayment of principal. Distributions are expected to be based in part on modelled coupon payments that are contingent on the Underlying Reference Index meeting specified performance thresholds on observation dates, and no coupon is assumed to be paid if those conditions are not met, which may result in reduced, irregular, or no distributions. Declines, heightened volatility, or prolonged drawdowns in the Underlying Reference Index increase the likelihood that coupon and autocall conditions will not be met. Early redemption features may limit the Fund’s participation in sustained or sharp increases in the Underlying Reference Index, causing the Fund to underperform traditional equity investments during strong market rallies. If an Autocallable is not redeemed prior to maturity and the Underlying Reference Index is below the applicable maturity barrier at maturity, the modelled principal repayment is reduced to reflect the negative performance of the Underlying Reference Index, and the Fund may experience significant losses, which could be substantial.

|||
| Defiance Silver Autocallable ETF | Underlying Reference Index Risk [Member] | ||||
| Prospectus [Line Items] | ||||
| Risk [Text Block] | Underlying Reference Index Risk. The Fund’s performance is significantly dependent on the performance and characteristics of the Cboe Edge Silver 35% Volatility Target 6% Decrement Index (the “Underlying Reference Index”). The Underlying Reference Index is rules-based and provides exposure to silver through silver futures contracts rather than direct investment in physical silver, and the performance of silver futures may diverge from the performance of spot silver prices due to factors such as contango, backwardation, roll yield, storage costs, liquidity conditions, and margin requirements. The Underlying Reference Index seeks to target a specified volatility level by increasing or decreasing its silver futures exposure based on observed market volatility, which may cause the Underlying Reference Index to reduce exposure during periods of elevated volatility and miss subsequent recoveries or sustained price increases. Silver prices have historically exhibited significant volatility, which may result in frequent and material exposure adjustments. The Underlying Reference Index generally adjusts exposure daily based on realized volatility and other model-driven signals, which may increase market timing risk and reduce returns in choppy, rapidly reversing, or highly volatile markets. The Underlying Reference Index may also incorporate trend-based features that may perform poorly in sideways or whipsaw markets and may cause exposure to be increased or decreased at unfavorable times. In addition, the Underlying Reference Index applies a fixed annual decrement of 6% and reflects assumed trading, roll, and financing costs that reduce the index level over time regardless of market performance, creating a persistent drag on returns. The Underlying Reference Index’s performance is path dependent, meaning results may be materially affected by the sequence and volatility of silver price movements, even if silver prices increase over a given period. The Underlying Reference Index relies on quantitative models, rules, and data inputs, and errors in index design or calculation, disruptions in the silver futures markets, or changes to index methodology could adversely affect the Underlying Reference Index and, consequently, the Fund.

| Defiance Silver Autocallable ETF | Derivatives Risks [Member] | ||||
| Prospectus [Line Items] | ||||
| Risk [Text Block] | Derivatives Risks. Derivatives are financial instruments that derive value from the underlying reference asset or assets, such as stocks, bonds, or funds (including ETFs), interest rates or indexes. The Fund’s investments in derivatives may pose risks in addition to, and greater than, those associated with directly investing in securities or other ordinary investments, including risk related to the market, imperfect correlation with underlying investments or the Fund’s other portfolio holdings, higher price volatility, lack of availability, counterparty risk, liquidity, valuation and legal restrictions. The use of derivatives is a highly specialized activity that involves investment techniques and risks different from those associated with ordinary portfolio securities transactions. The use of derivatives may result in larger losses or smaller gains than directly investing in securities. When the Fund uses derivatives, there may be an imperfect correlation between the value of the underlying reference asset and the derivative, which may prevent the Fund from achieving its investment objective. Because derivatives often require only a limited initial investment, the use of derivatives may expose the Fund to losses in excess of those amounts initially invested. In addition, the Fund’s investments in derivatives are subject to the following risks:
|
|||
| Defiance Silver Autocallable ETF | Swap Agreements [Member] | ||||
| Prospectus [Line Items] | ||||
| Risk [Text Block] |
The swap agreements in which the Fund invests are generally traded in the over-the-counter market, which generally has less transparency than exchange-traded derivative instruments. In a standard swap transaction, two parties agree to exchange the return (or differentials in rates of return) earned or realized on particular predetermined reference assets, securities, or instruments. The gross return to be exchanged or “swapped” between the parties is calculated based on a notional amount or the return on or change in value of a particular dollar amount invested in the reference asset.
If the Underlying Security experiences a significant price movement that causes a material change in the Fund’s net assets, the terms of a swap agreement between the Fund and its counterparty may permit the counterparty to close out the swap transaction with the Fund. In that event, the Fund may be unable to enter into another swap agreement or invest in other derivatives to maintain exposure consistent with its investment objective. This may temporarily reduce the Fund’s ability to maintain its intended level of synthetic exposure until replacement transactions can be established.
Certain of the swap agreements entered into by the Fund may be unfunded total return swaps, pursuant to which the Fund does not make an initial investment of the full notional amount of the swap. As a result, the Fund is exposed to the risk that its counterparty will be unable to meet its obligations under the swap agreement, and the Fund’s exposure to a counterparty generally equals the net amount owed to the Fund based on the daily change in value of the reference asset. In the event of a counterparty default or insolvency, the Fund may incur losses in excess of the collateral, if any, posted by the counterparty, and the timing and amount of any recovery may be uncertain. In addition, the use of unfunded swap agreements may create economic leverage for the Fund, which may magnify gains and losses and increase the volatility of the Fund’s returns.
|
|||
| Defiance Silver Autocallable ETF | Counterparty Risk [Member] | ||||
| Prospectus [Line Items] | ||||
| Risk [Text Block] | Counterparty Risk. The Fund is subject to counterparty risk by virtue of its investments in swap agreements. Transactions in some types of derivatives, including certain swap agreements, are required to be centrally cleared (“cleared derivatives”). In a transaction involving cleared derivatives, the Fund’s counterparty is a clearing house rather than a bank or broker. Since the Fund is not a member of clearing houses and only members of a clearing house (“clearing members”) can participate directly in the clearing house, the Fund will hold cleared derivatives through accounts at clearing members. In cleared derivatives positions, the Fund will make payments (including margin payments) to and receive payments from a clearing house through its accounts at clearing members. Customer collateral held at a clearing organization in connection with cleared derivatives is held in an omnibus account and, although such collateral is legally segregated by customer, it is operationally commingled. As a result, in the event of a clearing member’s bankruptcy, the Fund may be limited to recovering only a pro rata share of the assets segregated on behalf of the clearing member’s customers for the relevant account class. In addition, although clearing members guarantee performance of their clients’ obligations to the clearing house, there is a risk that the assets of the Fund might not be fully protected in the event of a clearing member’s insolvency. The Fund is also subject to the risk that a limited number of clearing members are willing to transact on the Fund’s behalf, which heightens the risks associated with a clearing member’s default. If a clearing member defaults, the Fund could lose some or all of the benefits of a transaction entered into by the Fund. If the Fund cannot find a clearing member to transact with on the Fund’s behalf, the Fund may be unable to effectively implement its investment strategy.

The Fund has a limited number of financial institutions that are authorized to purchase and redeem Shares directly from the Fund (known as “Authorized Participants” or “APs”). In addition, there may be a limited number of market makers and/or liquidity providers in the marketplace. To the extent either of the following events occur, Shares may trade at a material discount to NAV and possibly face delisting: (i) APs exit the business or otherwise become unable to process creation and/or redemption orders and no other APs step forward to perform these services; or (ii) market makers and/or liquidity providers exit the business or significantly reduce their business activities and no other entities step forward to perform their functions.
|
|||
| Defiance Silver Autocallable ETF | Cash Redemption Risk [Member] | ||||
| Prospectus [Line Items] | ||||
| Risk [Text Block] | Cash Redemption Risk. The Fund’s investment strategy may require it to redeem Shares for cash or to otherwise include cash as part of its redemption proceeds. For example, the Fund may not be able to redeem in-kind certain securities held by the Fund (e.g., derivative instruments). In such a case, the Fund may be required to sell or unwind portfolio investments to obtain the cash needed to distribute redemption proceeds. This may cause the Fund to recognize a capital gain that it might not have recognized if it had made a redemption in-kind. As a result, the Fund may pay out higher annual capital gain distributions than if the in-kind redemption process was used. By paying out higher annual capital gain distributions, investors may be subjected to increased capital gains taxes. Additionally, there may be brokerage costs or taxable gains or losses that may be imposed on the Fund in connection with a cash redemption that may not have occurred if the Fund had made a redemption in-kind. These costs could decrease the value of the Fund to the extent they are not offset by a transaction fee payable by an AP.

| Risk [Text Block] | Trading. Although Shares are listed on a national securities exchange, such as Cboe BZX Exchange (the “Exchange”), and may be traded on U.S. exchanges other than the Exchange, there can be no assurance that an active trading market for the Shares will develop or be maintained or that the Shares will trade with any volume, or at all, on any stock exchange. In stressed market conditions, the liquidity of Shares may begin to mirror the liquidity of the Fund’s underlying portfolio holdings, which can be significantly less liquid than Shares. Shares trade on the Exchange at market price that may be below, at or above the Fund’s NAV. Trading in Shares on the Exchange may be halted due to market conditions or for reasons that, in the view of the Exchange, make trading in Shares inadvisable. In addition, trading in Shares on the Exchange is subject to trading halts caused by extraordinary market volatility pursuant to the Exchange “circuit breaker” rules. There can be no assurance that the requirements of the Exchange necessary to maintain the listing of the Fund will continue to be met or will remain unchanged. As a result, the Fund could be adversely affected and be unable to implement its investment strategies in the event of an unscheduled closing.

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

The Fund relies on third-parties for a range of services, including custody.

| Prospectus [Line Items] | ||||
| Risk [Text Block] | SLV Risk. The Fund does not invest directly in SLV but may have indirect exposure to SLV through autocallable instruments linked to a reference index that obtains silver-related exposure through SLV. As a result, the Fund may be exposed to certain risks associated with SLV even though it does not own SLV shares. SLV’s performance is driven primarily by the price of silver, which is historically volatile and may fluctuate sharply due to global economic conditions, industrial demand, investor sentiment, interest rates, inflation expectations, currency movements, geopolitical events, and changes in silver supply and production. Because silver has significant industrial uses, economic downturns may reduce demand and adversely affect prices. In addition, increased hedging activity by silver producers or shifts in speculative positioning could contribute to rapid price declines. SLV’s net asset value is based on the LBMA Silver Price, which is determined through an electronic auction process administered by ICE Benchmark Administration. Disruptions, delays, technological failures, or concerns regarding the integrity or potential manipulation of this benchmark could adversely affect SLV’s valuation and market price. A loss of confidence in the benchmark process may also negatively impact investor demand for SLV and silver more broadly. SLV is concentrated solely in silver and therefore is more susceptible to price volatility than more diversified investment vehicles. Constraints in the physical silver market, including shortages of silver meeting SLV’s specifications, could impair the creation of new shares and cause SLV’s market price to trade at a premium or discount to its net asset value, increasing volatility. SLV is not affiliated with the Fund or its Adviser and is not registered under the 1940 Act. Fund shareholders have no rights with respect to SLV, including voting rights or rights to receive distributions, and do not benefit from the investor protections applicable to registered investment companies.

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