| Defiance Long/Short Space Economy vs. Legacy Communications ETF | Satellite Communications and Space Industry Risk [Member] | |||||||
| Prospectus [Line Items] | |||||||
| Risk [Text Block] | Satellite Communications and Space Industry Risk. Companies engaged in satellite communications and/or the space industry may be significantly impacted by rapid and significant technological advancements in the satellite communications and space industry that result in the obsolescence of a company’s products and/or services. Satellite companies are subject to competition from other satellite companies as well as terrestrial industries. Companies in the space industry may face significant competition from new entrants, including both governments and the private sector, and are thus subject to increased risk relative to companies operating in more established industries. Increased competition may result in the need for significant capital expenditures by these companies. These companies rely, to a large extent, on U.S. Government and non-U.S. government demand for their products and services and may be significantly affected by changes in government regulations and spending. Changes to an administration’s priorities with respect to space exploration and scientific discovery may result in budgetary cuts, government staff reductions, and/or program closures, which in turn may impact the profitability of these companies. Satellite companies are also subject to regulatory risks relating to the allocation of orbital positions and spectrum under the International Telecommunication Union as well as other regulatory bodies in foreign countries. These companies also rely upon obtaining government authorization to license and/or operate ground facilities used to operate their satellites and/or relay data. If a company fails to obtain or maintain regulatory authorizations with respect to orbital positions, spectrum, or associated ground facilities, the company may not be able to operate its existing satellites or expand its operations. Satellite companies are also subject to manufacturing delays, launch delays or failures, and operational and environmental risks (e.g., signal interference or space debris) that could limit their ability to utilize satellites needed to deliver services to customers. Such companies may also be subject to additional risks if they do not carry commercial launch or in-orbit insurance covering the full value of their satellites. In addition, these companies are heavily dependent upon patent and intellectual property rights. A company’s success in obtaining or protecting a patent related to satellite communications technologies, including the associated costs, are critical factors that may affect a company’s profitability.

| Defiance Long/Short Space Economy vs. Legacy Communications ETF | Industrials Sector Risk [Member] | |||||||
| Prospectus [Line Items] | |||||||
| Risk [Text Block] | Industrials Sector Risk. Companies operating in the industrials sector or issuers in industrials-related industries may be significantly affected by, among other things, worldwide economic growth, changes in supply and demand for specific products and services, product obsolescence, rapid technological developments, international, political and economic developments, environmental issues, tax and governmental regulatory policies, claims for environmental damage or product liability and general economic conditions. Any factors adversely affecting companies in the industrials sector could have a significant adverse impact on the Fund’s performance.
|
||||||
| Defiance Long/Short Space Economy vs. Legacy Communications ETF | Communication Services Sector Risk [Member] | |||||||
| Prospectus [Line Items] | |||||||
| Risk [Text Block] | Communication Services Sector Risk. Communication companies are particularly vulnerable to the potential obsolescence of products and services due to technological advancement and the innovation of competitors. Companies in the communications services sector may also be affected by other competitive pressures, such as pricing competition, as well as research and development costs, substantial capital requirements and government regulation. Additionally, fluctuating domestic and international demand, shifting demographics and often unpredictable changes in consumer tastes can drastically affect a communication company’s profitability. While all companies may be susceptible to network security breaches, certain companies in the communications services sector may be particular targets of hacking and potential theft of proprietary or consumer information or disruptions in service, which could have a material adverse effect on their businesses.
|
||||||
| Defiance Long/Short Space Economy vs. Legacy Communications ETF | Leverage Risk [Member] | |||||||
| Prospectus [Line Items] | |||||||
| Risk [Text Block] | Leverage Risk. Leverage is investment exposure that exceeds the initial amount invested. Leveraging investments, (e.g., by purchasing securities with borrowed money), is a speculative technique that increases investment risk while increasing investment opportunity. Leverage will magnify changes in the Fund’s net asset value and on the Fund’s investments. Derivatives and other transactions that give rise to leverage may cause the Fund’s performance to be more volatile than if the Fund had not been leveraged. Leveraging also may require that the Fund liquidate portfolio securities when it may not be advantageous to do so to satisfy its obligations or to meet segregation requirements. Further, the use of leverage may require the Fund to maintain assets as “cover,” maintain segregated asset accounts, or make margin payments, which might impair the Fund’s ability to sell a portfolio security or make an investment at a time when it would otherwise be favorable to do so, or require that the Fund sell a portfolio security at a disadvantageous time.
|
||||||
| Defiance Long/Short Space Economy vs. Legacy Communications ETF | Short Selling Risk [Member] | |||||||
| Prospectus [Line Items] | |||||||
| Risk [Text Block] | Short Selling Risk. The Fund may make short sales of securities, which involves selling a security it does not own in anticipation that the price of the security will decline. Short sales may involve substantial risk and leverage. Short sales expose the Fund to the risk that it will be required to buy (“cover”) the security sold short when the security has appreciated in value or is unavailable, thus resulting in a loss to the Fund. Short sales also involve the risk that losses may exceed the amount invested and may be unlimited.
|
||||||
| Defiance Long/Short Space Economy vs. Legacy Communications ETF | Equity Market Risk [Member] | |||||||
| Prospectus [Line Items] | |||||||
| Risk [Text Block] | Equity Market Risk. Common stocks, such as those held by the Fund, are generally exposed to greater risk than other types of securities, such as preferred stock and debt obligations, because common stockholders generally have inferior rights to receive payment from specific issuers. The equity securities held in the Fund’s portfolio may experience sudden, unpredictable drops in value or long periods of decline in value. This may occur because of factors that affect securities markets generally or factors affecting specific issuers, industries, or sectors in which the Fund invests.
|
||||||
| Defiance Long/Short Space Economy vs. Legacy Communications ETF | Management Risk [Member] | |||||||
| Prospectus [Line Items] | |||||||
| Risk [Text Block] | Management Risk. The risk that the investment techniques and risk analyses applied by the investment adviser will not produce the desired results and that legislative, regulatory, or tax developments may affect the investment techniques available to the investment adviser and the individual portfolio manager in connection with managing the Fund. There is no guarantee that the investment objective of the Fund will be achieved.
|
||||||
| Defiance Long/Short Space Economy vs. Legacy Communications ETF | Derivatives Risk [Member] | |||||||
| Prospectus [Line Items] | |||||||
| Risk [Text Block] | Derivatives Risk. Derivatives are financial instruments that derive value from the underlying reference asset or assets, such as stocks, bonds, or funds (including ETFs), interest rates or indexes. The Fund’s investments in derivatives may pose risks in addition to, and greater than, those associated with directly investing in securities or other ordinary investments, including risk related to the market, 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. |
||||||
| Defiance Long/Short Space Economy vs. Legacy Communications ETF | Futures Contracts [Member] | |||||||
| Prospectus [Line Items] | |||||||
| Risk [Text Block] | Futures Contracts. Risks of futures contracts include: (i) an imperfect correlation between the value of the futures contract and the underlying asset; (ii) possible lack of a liquid secondary market; (iii) the inability to close a futures contract when desired; (iv) losses caused by unanticipated market movements, which may be unlimited; (v) an obligation for the Fund to make daily cash payments to maintain its required margin, particularly at times when the Fund may have insufficient cash; and (vi) unfavorable execution prices from rapid selling. Unlike equities, which typically entitle the holder to a continuing stake in a corporation, futures contracts normally specify a certain date for settlement in cash based on the reference asset. As the futures contracts approach expiration, they may be replaced by similar contracts that have a later expiration. This process is referred to as “rolling.” If the market for these contracts is in “contango,” meaning that the prices of futures contracts in the nearer months are lower than the price of contracts in the distant months, the sale of the near-term month contract would be at a lower price than the longer-term contract, resulting in a cost to “roll” the futures contract. The actual realization of a potential roll cost will be dependent upon the difference in price of the near and distant contract.
|
||||||
| Defiance Long/Short Space Economy vs. Legacy Communications ETF | Options Contracts [Member] | |||||||
| Prospectus [Line Items] | |||||||
| Risk [Text Block] | Options Contracts. The use of options contracts involves investment strategies and risks different from those associated with ordinary portfolio securities transactions. The prices of options are volatile and are influenced by, among other things, actual and anticipated changes in the value of the underlying instrument, including the anticipated volatility, which are affected by fiscal and monetary policies and by national and international political and economic events, changes in the actual or implied volatility of 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 are substantially influenced by the value of the relevant underlying securities. The Fund may experience substantial downside from specific option positions and certain option positions held by the Fund may expire worthless. The options held by the Fund are exercisable at the strike price on their expiration date. As an option approaches its expiration date, its value typically increasingly moves with the value of the underlying instrument. However, prior to such date, the value of an option generally does not increase or decrease at the same rate as the underlying instrument. There may at times be an imperfect correlation between the movement in the 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. Additionally, as the Fund may continuously maintain indirect exposure to one or more of the underlying securities through the use of options contracts, as the options contracts it holds are exercised or expire it will enter into new options contracts, a practice referred to as “rolling.” If the expiring options contracts do not generate proceeds enough to cover the cost of entering into new options contracts, the Fund may experience losses.
|
||||||
| Defiance Long/Short Space Economy vs. Legacy Communications ETF | Swap Agreements [Member] | |||||||
| Prospectus [Line Items] | |||||||
| Risk [Text Block] | Swap Agreements. The use of swap transactions is a highly specialized activity that involves investment techniques and risks different from those associated with ordinary portfolio securities transactions. Whether the Fund will be successful in using swap agreements to achieve its investment goal depends on the ability of the Adviser to structure such swap agreements in accordance with the Fund’s investment objective and to identify appropriate counterparties. If the Adviser is unable to enter into swap agreements that provide the desired synthetic exposure to the underlying security, the Fund may not meet its stated investment objective. Additionally, any financing, transaction, or other costs associated with using swap transactions may have the effect of lowering the Fund’s return.
The swap agreements in which the Fund invests are generally traded in the over-the-counter market, which generally has less transparency than exchange-traded 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 Long/Short Space Economy vs. Legacy Communications ETF | Equity Total Return Swaps [Member] | |||||||
| Prospectus [Line Items] | |||||||
| Risk [Text Block] | Equity Total Return Swaps. A total return swap (also sometimes referred to as a synthetic equity swap or “contract for difference” when written with respect to an equity security or basket of equity securities) is an agreement between two parties under which the parties agree to make payments to each other so as to replicate the economic consequences that would apply had a purchase or short sale of the underlying reference instrument or index thereof taken place. For example, one party agrees to pay the other party the total return earned or realized on the notional amount of an underlying equity security and any dividends declared with respect to that equity security. In return the other party makes payments, typically at a floating rate, calculated based on the notional amount.
|
||||||
| Defiance Long/Short Space Economy vs. Legacy Communications ETF | Counterparty Risk [Member] | |||||||
| Prospectus [Line Items] | |||||||
| Risk [Text Block] | Counterparty Risk. To the extent contemplated by its investment strategy, the Fund may use derivative instruments, such as options, swaps, futures contracts and other instruments, to obtain or manage investment exposure. Derivatives may be subject to counterparty risk, meaning the risk that a counterparty, clearing member or clearing house will be unwilling or unable to perform its obligations to the Fund due to bankruptcy, insolvency, financial distress, operational failure or other default. If a counterparty or clearing member defaults, the Fund may lose the expected benefit of the transaction, experience delays or costs in recovering collateral or other amounts owed to it, or be required to enter into replacement transactions on less favorable terms, if at all. The Fund also may be unable to implement its investment strategy effectively if suitable counterparties or clearing members are unavailable.
|
||||||
| Defiance Long/Short Space Economy vs. Legacy Communications ETF | Concentration Risk [Member] | |||||||
| Prospectus [Line Items] | |||||||
| Risk [Text Block] | Concentration Risk. The Fund will have concentrated investment exposure to the industries related to the Industrials and Communication Services sectors. As a result, the value of Shares may rise and fall more than the value of shares that invest in securities of companies in a broader range of industries.

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

| Defiance Long/Short Space Economy vs. Legacy Communications ETF | Trading [Member] | |||||||
| Prospectus [Line Items] | |||||||
| Risk [Text Block] | Trading. Although Shares are listed on a national securities exchange, such as Cboe BZX Exchange, Inc. (the “Exchange”), and may be traded on U.S. exchanges other than the Exchange, there can be no assurance that Shares will trade with any volume, or at all, on any stock exchange. In stressed market conditions, the liquidity of Shares may begin to mirror the liquidity of the Fund’s underlying portfolio holdings, which can be significantly less liquid than Shares. This adverse effect on liquidity for the Fund’s shares may lead to wider bid-ask spreads and differences between the market price of the Fund’s shares and the underlying value of the shares.
|
||||||
| Defiance Long/Short Space Economy vs. Legacy Communications ETF | Liquidity Risk [Member] | |||||||
| Prospectus [Line Items] | |||||||
| Risk [Text Block] | Liquidity Risk. In certain circumstances, such as the disruption of the orderly markets for the financial instruments in which the Fund invests, the Fund might not be able to acquire or dispose of certain holdings quickly or at prices that represent true market value in the judgment of the Adviser. Markets for the financial instruments in which the Fund invests may be disrupted by a number of events, including but not limited to economic crises, health crises, natural disasters, excessive volatility, new legislation, or regulatory changes inside or outside of the U.S. These situations may have an impact on the liquidity of the Fund’s own shares.
|
||||||
| Defiance Long/Short Space Economy vs. Legacy Communications 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 Long/Short Space Economy vs. Legacy Communications ETF | Foreign Securities Risk [Member] | |||||||
| Prospectus [Line Items] | |||||||
| Risk [Text Block] | Foreign Securities Risk. Investments in securities or other instruments of non-U.S. issuers involve certain risks not involved in domestic investments and may experience more rapid and extreme changes in value than investments in securities of U.S. companies. Financial markets in foreign countries often are not as developed, efficient, or liquid as financial markets in the United States, and therefore, the prices of non-U.S. securities and instruments can be more volatile. In addition, the Fund will be subject to risks associated with adverse political and economic developments in foreign countries, which may include the imposition of economic sanctions. Generally, there is less readily available and reliable information about non-U.S. issuers due to less rigorous disclosure or accounting standards and regulatory practices. Investments in foreign companies’ securities, including investments via depositary receipts, are subject to special risks, including the following:

| Defiance Long/Short Space Economy vs. Legacy Communications 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 securities in its portfolio. 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 Long/Short Space Economy vs. Legacy Communications ETF | Liquidity Risks [Member] | |||||||
| Prospectus [Line Items] | |||||||
| Risk [Text Block] | Liquidity Risk. Some securities held by the Fund may be difficult to sell or be illiquid, particularly during times of market turmoil. Markets for securities or financial instruments could be disrupted by a number of events, including, but not limited to, an economic crisis, natural disasters, epidemics/pandemics, new legislation or regulatory changes inside or outside the United States. Illiquid securities may be difficult to value, especially in changing or volatile markets. If the Fund is forced to sell an illiquid security at an unfavorable time or price, the Fund may be adversely impacted. There is no assurance that a security that is deemed liquid when purchased will continue to be liquid. Market illiquidity may cause losses for the Fund.
|
||||||
| Defiance Long/Short Space Economy vs. Legacy Communications 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 Long/Short Space Economy vs. Legacy Communications 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 Long/Short Space Economy vs. Legacy Communications 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 Long/Short Space Economy vs. Legacy Communications ETF | IPO/SPAC/de-SPAC Risk [Member] | |||||||
| Prospectus [Line Items] | |||||||
| Risk [Text Block] | IPO/SPAC/de-SPAC Risk. The Fund may invest in companies that have recently completed an IPO, are derived from a SPAC, or are derived from a de-SPAC business combination, including SPACs that have not yet completed a business combination (“Pre-Combination” SPACs). These companies may be unseasoned and lack a trading history, a track record of reporting to investors, and widely available research coverage. IPOs and stocks derived from SPACs or de-SPAC business combinations are thus often subject to extreme price volatility and speculative trading. These stocks may have above-average price appreciation in connection with the IPO or relevant transaction prior to the Fund’s purchase. The price of stocks selected may not continue to appreciate and the performance of these stocks may not replicate the performance exhibited in the past. In addition, IPOs and stocks derived from SPACs or de-SPAC business combinations may share similar illiquidity risks of private equity and venture capital. The ownership of many IPOs and stocks derived from SPACs or de-SPACs often includes large holdings by venture capital and private equity investors who seek to sell their shares in the public market in the months following an IPO or relevant transaction when shares restricted by lock-up are released, causing greater volatility and possible downward pressure during the time that locked-up shares are released, and SPAC investments may involve additional risks, including pricing misalignment, limited publicly available information, dependence on the sponsor’s ability to identify and consummate a business combination, potential conflicts of interest, and, in the case of Pre-Combination SPACs, the risk that a suitable business combination is not completed within a specified time period, which may result in liquidation of the SPAC.
|
||||||
| Defiance Long/Short Space Economy vs. Legacy Communications ETF | Warrants and Rights Risk [Member] | |||||||
| Prospectus [Line Items] | |||||||
| Risk [Text Block] | Warrants and Rights Risk. The Fund may receive or invest in warrants or rights in connection with its purchase of equity securities, including SPAC units. Warrants and rights do not represent an ownership interest in the issuer but instead confer the right to purchase underlying securities at a specified price, subject to the terms of the instrument. Accordingly, holders of warrants or rights generally do not have voting rights, receive dividends, or have rights with respect to the assets of the issuer. Investments in warrants and rights are speculative and involve a high degree of risk. The value of warrants and rights may be highly volatile and may not move in tandem with the value of the underlying securities. In addition, warrants and rights are complex financial instruments, and their accounting treatment and valuation involve significant judgment. For example, depending on their terms and the specific facts and circumstances of the issuer, warrants may be classified as equity or as assets or liabilities of the issuer, which can affect their valuation and increase the risk of error. Warrants and rights are also subject to the risk that they may expire worthless if not exercised or sold prior to expiration. In addition, the effective cost of acquiring the underlying securities upon exercise (i.e., the purchase price of the warrant or right plus the exercise price) may exceed the market value of the underlying securities at the time of exercise. With respect to SPAC-related investments, if a SPAC does not complete a business combination within the specified time period, any associated warrants or rights held by the Fund may expire worthless.
|
||||||
| Defiance Long/Short Space Economy vs. Legacy Communications 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”). As a RIC, the Fund will not be subject to U.S. federal income tax on the portion of its net investment income and net capital gain that it distributes to shareholders, provided that it satisfies certain requirements of the Code. If the Fund does not qualify as a RIC for any taxable year and certain relief provisions are not available, the Fund’s taxable income will be subject to tax at the Fund level and to a further tax at the shareholder level when such income is distributed. To comply with the asset diversification test applicable to a RIC, the Fund will attempt to ensure that the value of swap contracts on shares of a single issuer does not exceed 25% of the Fund’s value at the close of any quarter. If the value of swap contracts on shares of a single issuer were to exceed 25% of the Fund’s total assets at the end of a tax quarter, the Fund, generally, has a grace period to cure such lack of compliance. If the Fund fails to timely cure, it may no longer be eligible to be treated as a RIC.

| Prospectus [Line Items] | |||||||
| Risk [Text Block] | The Fund may not achieve its investment objective and there is a risk that you could lose all of your money invested in the Fund. | ||||||
| Defiance Long/Short Space Economy vs. Legacy Communications 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 Long/Short AI Compute vs. Legacy Software ETF | Leverage Risk [Member] | |||||||
| Prospectus [Line Items] | |||||||
| Risk [Text Block] | Leverage Risk. Leverage is investment exposure that exceeds the initial amount invested. Leveraging investments, (e.g., by purchasing securities with borrowed money), is a speculative technique that increases investment risk while increasing investment opportunity. Leverage will magnify changes in the Fund’s net asset value and on the Fund’s investments. Derivatives and other transactions that give rise to leverage may cause the Fund’s performance to be more volatile than if the Fund had not been leveraged. Leveraging also may require that the Fund liquidate portfolio securities when it may not be advantageous to do so to satisfy its obligations or to meet segregation requirements. Further, the use of leverage may require the Fund to maintain assets as “cover,” maintain segregated asset accounts, or make margin payments, which might impair the Fund’s ability to sell a portfolio security or make an investment at a time when it would otherwise be favorable to do so, or require that the Fund sell a portfolio security at a disadvantageous time.
|
||||||
| Defiance Long/Short AI Compute vs. Legacy Software ETF | Short Selling Risk [Member] | |||||||
| Prospectus [Line Items] | |||||||
| Risk [Text Block] | Short Selling Risk. The Fund may make short sales of securities, which involves selling a security it does not own in anticipation that the price of the security will decline. Short sales may involve substantial risk and leverage. Short sales expose the Fund to the risk that it will be required to buy (“cover”) the security sold short when the security has appreciated in value or is unavailable, thus resulting in a loss to the Fund. Short sales also involve the risk that losses may exceed the amount invested and may be unlimited.

| Risk [Text Block] | Equity Market Risk. Common stocks, such as those held by the Fund, are generally exposed to greater risk than other types of securities, such as preferred stock and debt obligations, because common stockholders generally have inferior rights to receive payment from specific issuers. The equity securities held in the Fund’s portfolio may experience sudden, unpredictable drops in value or long periods of decline in value. This may occur because of factors that affect securities markets generally or factors affecting specific issuers, industries, or sectors in which the Fund invests.

| Risk [Text Block] | Derivatives Risk. Derivatives are financial instruments that derive value from the underlying reference asset or assets, such as stocks, bonds, or funds (including ETFs), interest rates or indexes. The Fund’s investments in derivatives may pose risks in addition to, and greater than, those associated with directly investing in securities or other ordinary investments, including risk related to the market, 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. |

| Risk [Text Block] | Futures Contracts. Risks of futures contracts include: (i) an imperfect correlation between the value of the futures contract and the underlying asset; (ii) possible lack of a liquid secondary market; (iii) the inability to close a futures contract when desired; (iv) losses caused by unanticipated market movements, which may be unlimited; (v) an obligation for the Fund to make daily cash payments to maintain its required margin, particularly at times when the Fund may have insufficient cash; and (vi) unfavorable execution prices from rapid selling. Unlike equities, which typically entitle the holder to a continuing stake in a corporation, futures contracts normally specify a certain date for settlement in cash based on the reference asset. As the futures contracts approach expiration, they may be replaced by similar contracts that have a later expiration. This process is referred to as “rolling.” If the market for these contracts is in “contango,” meaning that the prices of futures contracts in the nearer months are lower than the price of contracts in the distant months, the sale of the near-term month contract would be at a lower price than the longer-term contract, resulting in a cost to “roll” the futures contract. The actual realization of a potential roll cost will be dependent upon the difference in price of the near and distant contract.

| Defiance Long/Short AI Compute vs. Legacy Software ETF | Options Contracts [Member] | |||||||
| Prospectus [Line Items] | |||||||
| Risk [Text Block] | Options Contracts. The use of options contracts involves investment strategies and risks different from those associated with ordinary portfolio securities transactions. The prices of options are volatile and are influenced by, among other things, actual and anticipated changes in the value of the underlying instrument, including the anticipated volatility, which are affected by fiscal and monetary policies and by national and international political and economic events, changes in the actual or implied volatility of 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 are substantially influenced by the value of the relevant underlying securities. The Fund may experience substantial downside from specific option positions and certain option positions held by the Fund may expire worthless. The options held by the Fund are exercisable at the strike price on their expiration date. As an option approaches its expiration date, its value typically increasingly moves with the value of the underlying instrument. However, prior to such date, the value of an option generally does not increase or decrease at the same rate as the underlying instrument. There may at times be an imperfect correlation between the movement in the 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. Additionally, as the Fund may continuously maintain indirect exposure to one or more of the underlying securities through the use of options contracts, as the options contracts it holds are exercised or expire it will enter into new options contracts, a practice referred to as “rolling.” If the expiring options contracts do not generate proceeds enough to cover the cost of entering into new options contracts, the Fund may experience losses.

| Defiance Long/Short AI Compute vs. Legacy Software ETF | Swap Agreements [Member] | |||||||
| Prospectus [Line Items] | |||||||
| Risk [Text Block] | Swap Agreements. The use of swap transactions is a highly specialized activity that involves investment techniques and risks different from those associated with ordinary portfolio securities transactions. Whether the Fund will be successful in using swap agreements to achieve its investment goal depends on the ability of the Adviser to structure such swap agreements in accordance with the Fund’s investment objective and to identify appropriate counterparties. If the Adviser is unable to enter into swap agreements that provide the desired synthetic exposure to the underlying security, the Fund may not meet its stated investment objective. Additionally, any financing, transaction, or other costs associated with using swap transactions may have the effect of lowering the Fund’s return.
The swap agreements in which the Fund invests are generally traded in the over-the-counter market, which generally has less transparency than exchange-traded 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.

| Risk [Text Block] | Equity Total Return Swaps. A total return swap (also sometimes referred to as a synthetic equity swap or “contract for difference” when written with respect to an equity security or basket of equity securities) is an agreement between two parties under which the parties agree to make payments to each other so as to replicate the economic consequences that would apply had a purchase or short sale of the underlying reference instrument or index thereof taken place. For example, one party agrees to pay the other party the total return earned or realized on the notional amount of an underlying equity security and any dividends declared with respect to that equity security. In return the other party makes payments, typically at a floating rate, calculated based on the notional amount.

| Risk [Text Block] | Counterparty Risk. To the extent contemplated by its investment strategy, the Fund may use derivative instruments, such as options, swaps, futures contracts and other instruments, to obtain or manage investment exposure. Derivatives may be subject to counterparty risk, meaning the risk that a counterparty, clearing member or clearing house will be unwilling or unable to perform its obligations to the Fund due to bankruptcy, insolvency, financial distress, operational failure or other default. If a counterparty or clearing member defaults, the Fund may lose the expected benefit of the transaction, experience delays or costs in recovering collateral or other amounts owed to it, or be required to enter into replacement transactions on less favorable terms, if at all. The Fund also may be unable to implement its investment strategy effectively if suitable counterparties or clearing members are unavailable.

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

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

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

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

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

Markets for securities or financial instruments could be disrupted by a number of events, including, but not limited to, an economic crisis, natural disasters, epidemics/pandemics, new legislation or regulatory changes inside or outside the United States. Illiquid securities may be difficult to value, especially in changing or volatile markets. If the Fund is forced to sell an illiquid security at an unfavorable time or price, the Fund may be adversely impacted.

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.

| Risk [Text Block] | IPO/SPAC/de-SPAC Risk. The Fund may invest in companies that have recently completed an IPO, are derived from a SPAC, or are derived from a de-SPAC business combination, including SPACs that have not yet completed a business combination (“Pre-Combination” SPACs). These companies may be unseasoned and lack a trading history, a track record of reporting to investors, and widely available research coverage. IPOs and stocks derived from SPACs or de-SPAC business combinations are thus often subject to extreme price volatility and speculative trading. These stocks may have above-average price appreciation in connection with the IPO or relevant transaction prior to the Fund’s purchase. The price of stocks selected may not continue to appreciate and the performance of these stocks may not replicate the performance exhibited in the past. In addition, IPOs and stocks derived from SPACs or de-SPAC business combinations may share similar illiquidity risks of private equity and venture capital. The ownership of many IPOs and stocks derived from SPACs or de-SPACs often includes large holdings by venture capital and private equity investors who seek to sell their shares in the public market in the months following an IPO or relevant transaction when shares restricted by lock-up are released, causing greater volatility and possible downward pressure during the time that locked-up shares are released, and SPAC investments may involve additional risks, including pricing misalignment, limited publicly available information, dependence on the sponsor’s ability to identify and consummate a business combination, potential conflicts of interest, and, in the case of Pre-Combination SPACs, the risk that a suitable business combination is not completed within a specified time period, which may result in liquidation of the SPAC.

| Defiance Long/Short AI Compute vs. Legacy Software ETF | Warrants and Rights Risk [Member] | |||||||
| Prospectus [Line Items] | |||||||
| Risk [Text Block] | Warrants and Rights Risk. The Fund may receive or invest in warrants or rights in connection with its purchase of equity securities, including SPAC units. Warrants and rights do not represent an ownership interest in the issuer but instead confer the right to purchase underlying securities at a specified price, subject to the terms of the instrument. Accordingly, holders of warrants or rights generally do not have voting rights, receive dividends, or have rights with respect to the assets of the issuer. Investments in warrants and rights are speculative and involve a high degree of risk. The value of warrants and rights may be highly volatile and may not move in tandem with the value of the underlying securities. In addition, warrants and rights are complex financial instruments, and their accounting treatment and valuation involve significant judgment. For example, depending on their terms and the specific facts and circumstances of the issuer, warrants may be classified as equity or as assets or liabilities of the issuer, which can affect their valuation and increase the risk of error. Warrants and rights are also subject to the risk that they may expire worthless if not exercised or sold prior to expiration. In addition, the effective cost of acquiring the underlying securities upon exercise (i.e., the purchase price of the warrant or right plus the exercise price) may exceed the market value of the underlying securities at the time of exercise. With respect to SPAC-related investments, if a SPAC does not complete a business combination within the specified time period, any associated warrants or rights held by the Fund may expire worthless.

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

| Risk [Text Block] | Artificial Intelligence Risk. Issuers engaged in artificial intelligence typically have high research and capital expenditures and, as a result, their profitability can vary widely, if they are profitable at all. The space in which they are engaged is highly competitive and issuers’ products and services may become obsolete very quickly. These companies are heavily dependent on intellectual property rights and may be adversely affected by loss or impairment of those rights. The issuers are also subject to legal, regulatory and political changes that may have a large impact on their profitability. A failure in an issuer’s product or even questions about the safety of the product could be devastating to the issuer, especially if it is the marquee product of the issuer. It can be difficult to accurately capture what qualifies as an artificial intelligence company.

As technological advancements accelerate and demand for data processing and storage grows, datacenter companies must continuously upgrade infrastructure and expand capacity, leading to high capital expenditures and increased operational costs. The highly competitive nature of the industry often results in aggressive pricing strategies that compress profit margins. Additionally, fluctuations in demand for data services, driven by economic conditions and shifts in technology trends, can lead to under-utilization of capacity, negatively affecting revenue streams and overall profitability. Furthermore, companies must navigate complex regulatory environments and manage significant energy consumption and environmental impact, adding to operational burdens and costs.

| Risk [Text Block] | Semiconductors & Semiconductor Equipment Industry Risk. Semiconductor companies may face intense competition, both domestically and internationally, and such competition may have an adverse effect on their profit margins. Semiconductor companies may have limited product lines, markets, financial resources or personnel. Semiconductor companies’ supply chain and operations are dependent on the availability of materials that meet exacting standards and the use of third parties to provide components and services. Semiconductor companies may rely on a limited number of suppliers, or upon suppliers in a single location, for certain materials, equipment or tools. Finding and qualifying alternate or additional suppliers can be a lengthy process that can cause production delays or impose unforeseen costs, and such alternatives may not be available at all. Production can be disrupted by the unavailability of resources, such as water, silicon, electricity, gases and other materials. Suppliers may also increase prices or encounter cybersecurity or other issues that can disrupt production or increase production costs.

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

| Risk [Text Block] | Technology Sector Risk. The technology sector is characterized by rapid innovation, intense competition, and frequent changes in consumer preferences, which can lead to significant market volatility. Companies in this sector are particularly vulnerable to product obsolescence, regulatory scrutiny, and supply chain disruptions that may impact production and distribution. Increased global competition, including from foreign companies with lower production costs, can pressure profit margins and market share. Additionally, many technology companies rely heavily on intellectual property protections, and any loss or infringement of patents, copyrights, or trade secrets could negatively impact revenues. Smaller and newly established technology firms may be especially susceptible to economic downturns, capital constraints, and shifts in market sentiment, leading to heightened stock price volatility.
