| Nicholas Fixed Income Alternative 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. 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:
|
|||
| Nicholas Fixed Income Alternative ETF | Option Contracts [Member] | ||||
| Prospectus [Line Items] | ||||
| Risk [Text Block] | Option Contracts. The use of option 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, changes in interest or currency exchange rates, including the anticipated volatility, which are affected by fiscal and monetary policies and by national and international political, changes in the actual or implied volatility or the reference asset, the time remaining until the expiration of the option contract and economic events. There may at times be an imperfect correlation between the movement in values option contracts and the reference asset, and there may at times not be a liquid secondary market for certain option contracts.
|
|||
| Nicholas Fixed Income Alternative 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 option contracts which exposes the Fund to the risk that the counterparty will not fulfill its obligation to the Fund. Counterparty risk may arise because of the counterparty’s financial condition (i.e., financial difficulties, bankruptcy, or insolvency), market activities and developments, or other reasons, whether foreseen or note. A counterparty’s inability to fulfill its obligation may result in significant financial loss to the Fund and the Fund may be unable to recover its investment from such counterparty, or may obtain a limited and/or delayed recovery.
In addition, the Fund may enter into option contracts with a limited number of counterparties, which may increase the Fund’s exposure to counterparty credit risk. Further, there is a risk that no suitable counterparties will be willing to enter into, or continue to enter into, transactions with the Fund and, as a result, the Fund may not be able to achieve its leveraged investment objective or may decide to change its leveraged investment objective.
|
|||
| Nicholas Fixed Income Alternative ETF | Strategy Risk [Member] | ||||
| Prospectus [Line Items] | ||||
| Risk [Text Block] | Strategy Risk. The Fund’s investment strategy is based on the use of vertical transaction spreads that, as noted above, offer defined risk levels. If the Fund’s vertical transaction spreads frequently experience losses, in turn, the Fund would experience losses. In addition, the Fund’s investment strategy may not offer as much potential growth as other ETFs. By design, the Fund’s investment strategy has a lower risk profile than certain other ETFs (e.g., equity ETFs), which in turn, limits return protentional vs investing directly in some other ETFs.
|
|||
| Nicholas Fixed Income Alternative ETF | Equity Market Risk [Member] | ||||
| Prospectus [Line Items] | ||||
| Risk [Text Block] | Equity Market Risk. By virtue of the Fund’s investments in option contracts equity ETFs and equity indices, the Fund is exposed to common stocks indirectly which subjects the Fund to equity market risk. Common stocks 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. Equity securities 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.
|
|||
| Nicholas Fixed Income Alternative 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.
|
|||
| Nicholas Fixed Income Alternative 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. Although U.S. Treasuries are backed by the U.S. government, those government policies may change both in terms of the payment of interest and in the payment of principal. Furthermore, while holding a treasury until maturity can guarantee principal, selling a treasury prior to maturity or buying a treasury subsequent to issue date may put principal at risk.
|
|||
| Nicholas Fixed Income Alternative ETF | Hedging Transactions Risk [Member] | ||||
| Prospectus [Line Items] | ||||
| Risk [Text Block] | Hedging Transactions Risk. Hedging transactions involve risks different than those of underlying investments. In particular, the variable degree of correlation between price movements of hedging transactions and price movements in the position being hedged means that losses on the hedge may be greater than gains in the value of the Fund’s positions, opportunities for gain may be limited or that there may be losses on both parts of a transaction. Whether the Fund hedges successfully will depend on the Sub- Advisor’s ability to predict pertinent market movements and the degree of correlation between the performance of the instruments used in the hedging strategy and the performance of the investments in the portfolio being hedged. There can be no assurance that any hedging transactions the Fund engages in will be successful. In addition, it is not possible to hedge fully or perfectly against any risk, and hedging involves its own costs.

| Nicholas Fixed Income Alternative ETF | General Market Risk [Member] | ||||
| Prospectus [Line Items] | ||||
| Risk [Text Block] | General 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), interest rates, global demand for particular products or resources, natural disasters or events, pandemic diseases, terrorism, regulatory events, and government controls.
|
|||
| Nicholas Fixed Income Alternative ETF | Illiquid Investments Risk [Member] | ||||
| Prospectus [Line Items] | ||||
| Risk [Text Block] | Illiquid Investments Risk. The Fund may, at times, hold illiquid investments, by virtue of the absence of a readily available market for certain of its investments, or because of legal or contractual restrictions on sales. The Fund could lose money if it is unable to dispose of an investment at a time or price that is most beneficial to the Fund.
|
|||
| Nicholas Fixed Income Alternative ETF | Interest Rates Risk [Member] | ||||
| Prospectus [Line Items] | ||||
| Risk [Text Block] | Interest Rate Risk. The value of the Fund’s investments in fixed income Treasury securities will fluctuate with changes in interest rates. Typically, a rise in interest rates causes a decline in the value of Treasury securities owned by the Fund. On the other hand, if rates fall, the value of Treasury securities generally increases. Due to the current inflationary period and rising interest rates, the value of the Fund’s Treasury securities may decline in value. In general, the market price of fixed income securities with longer maturities will increase or decrease more in response to changes in interest rates than shorter-term securities.
|
|||
| Nicholas Fixed Income Alternative 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 or Sub-Adviser’s success or failure to implement investment strategies for the Fund.
|
|||
| Nicholas Fixed Income Alternative ETF | Market Events Risk [Member] | ||||
| Prospectus [Line Items] | ||||
| Risk [Text Block] | Market Events Risk. The Fund’s investments are subject to changes in general economic conditions, general market fluctuations and the risks inherent in investment in securities and other financial instruments. Investment markets can be volatile and prices of investments can change substantially due to various factors including, but not limited to, economic growth or recession, changes in interest rates, inflation, changes in the actual or perceived creditworthiness of issuers, and general market liquidity. The Fund is subject to the risk that geopolitical events will disrupt securities and other financial markets and adversely affect global economies and markets. Local, regional or global events such as war, military conflicts, acts of terrorism, natural disasters, the spread of infectious illness or other public health issues, or other events could have a significant impact on the Fund and its investments. Continuing uncertainties regarding interest rates, rising inflation, political events, rising government debt in the U.S. and trade tensions also contribute to market volatility. Conflict, loss of life and disaster connected to ongoing armed conflict between Ukraine and Russia in Europe and between Israel and Hamas in the Middle East could have severe adverse effects on the related region, including significant adverse effects on the regional or global economies and the markets for certain securities. The U.S. and the European Union have imposed sanctions on certain Russian individuals and companies, including certain financial institutions, and have limited certain exports and imports to and from Russia. These conflicts have contributed to recent market volatility and may continue to do so.
|
|||
| Nicholas Fixed Income Alternative ETF | Newer Fund Risk [Member] | ||||
| Prospectus [Line Items] | ||||
| Risk [Text Block] | Newer Fund Risk. The Fund is a recently organized management investment company with limited operating history. As a result, prospective investors have a limited track record or history on which to base their investment decisions. There can be no assurance that the Fund will maintain an economically viable size.
|
|||
| Nicholas Fixed Income Alternative 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, Adviser, and Sub-Adviser seek to reduce these operational risks through controls and procedures, there is no way to completely protect against such risks.
|
|||
| Nicholas Fixed Income Alternative ETF | Risk Lose Money [Member] | ||||
| Prospectus [Line Items] | ||||
| Risk [Text Block] | As with any investment, there is a risk that you could lose all or a portion of your investment in the Fund. | |||
| Nicholas Fixed Income Alternative 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. This may increase a Fund’s volatility and cause the performance of a relatively smaller number of issuers to have a greater impact on the Fund’s performance.
|
|||
| Nicholas Global Equity and Income 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 indices. 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, 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 Index 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:
|
|||
| Nicholas Global Equity and 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 options contracts. Transactions in some types of derivatives, including options, 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 their accounts at clearing members. Customer funds held at a clearing organization in connection with any options contracts are held in a commingled omnibus account and are not identified to the name of the clearing member’s individual customers. As a result, assets deposited by the Fund with any clearing member as margin for options may, in certain circumstances, be used to satisfy losses of other clients of the Fund’s clearing member. 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 the clearing member’s bankruptcy, as the Fund would be limited to recovering only a pro rata share of all available funds segregated on behalf of the clearing member’s customers for the relevant account class. 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 with the clearing member. 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.
|
|||
| Nicholas Global Equity and Income ETF | Equity Market Risk [Member] | ||||
| Prospectus [Line Items] | ||||
| Risk [Text Block] | Equity Market Risk. 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. 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 issuers. 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. Factors that could impact the market value of an equity security include a company’s business performance, investor perceptions, stock market trends and general economic conditions.
|
|||
| Nicholas Global Equity and 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.
|
|||
| Nicholas Global Equity and 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.

|
|||
| Nicholas Global Equity and 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.
|
|||
| Nicholas Global Equity and 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 NYSE Arca, Inc. (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 a 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.
|
|||
| Nicholas Global Equity and 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 or Sub-Adviser’s success or failure to implement investment strategies for the Fund.
|
|||
| Nicholas Global Equity and Income ETF | Market Events Risk [Member] | ||||
| Prospectus [Line Items] | ||||
| Risk [Text Block] | Market Events Risk. The Fund’s investments are subject to changes in general economic conditions, general market fluctuations and the risks inherent in investment in securities and other financial instruments. Investment markets can be volatile and prices of investments can change substantially due to various factors including, but not limited to, economic growth or recession, changes in interest rates, inflation, changes in the actual or perceived creditworthiness of issuers, and general market liquidity. The Fund is subject to the risk that geopolitical events will disrupt securities and other financial markets and adversely affect global economies and markets. Local, regional or global events such as war, military conflicts, acts of terrorism, natural disasters, the spread of infectious illness or other public health issues, or other events could have a significant impact on the Fund and its investments. Continuing uncertainties regarding interest rates, rising inflation, political events, rising government debt in the U.S. and trade tensions also contribute to market volatility. Conflict, loss of life and disaster connected to ongoing armed conflict between Ukraine and Russia in Europe and between Israel and Hamas in the Middle East could have severe adverse effects on the related region, including significant adverse effects on the regional or global economies and the markets for certain securities. The U.S. and the European Union have imposed sanctions on certain Russian individuals and companies, including certain financial institutions, and have limited certain exports and imports to and from Russia. These conflicts have contributed to recent market volatility and may continue to do so.
|

| Prospectus [Line Items] | ||||
| Risk [Text Block] | Newer Fund Risk. The Fund is a recently organized management investment company with limited operating history. As a result, prospective investors have a limited track record or history on which to base their investment decisions.
|
|||
| Nicholas Global Equity and 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, Adviser, and Sub-Adviser seek to reduce these operational risks through controls and procedures, there is no way to completely protect against such risks.
|
|||
| Nicholas Global Equity and Income ETF | Index ETF Risks [Member] | ||||
| Prospectus [Line Items] | ||||
| Risk [Text Block] | Index ETF Risks. The Fund invests in Index ETFs, which subjects the Fund to the following risks in addition to ETF Risks (described below):
|
|||
| Nicholas Global Equity and Income ETF | Indirect Investment Risk [Member] | ||||
| Prospectus [Line Items] | ||||
| Risk [Text Block] | Indirect Investment Risk. The Fund’s exposure to various Indices involves indirect investment risk. None of the Indices are affiliated with the Trust, the Fund, the Adviser, the Sub-Adviser, or their respective affiliates, and are not associated with this offering. Investors in the Fund are susceptible to declines in the performance of the Indices in which the Fund invests.
|
|||
| Nicholas Global Equity and Income ETF | Index Trading Risk [Member] | ||||
| Prospectus [Line Items] | ||||
| Risk [Text Block] | Index Trading Risk. The price of an Index may be highly volatile and could continue to be subject to wide fluctuations in response to various factors. Market volatility, unrelated to company performance, has been observed in response to economic conditions and geopolitical events.
|
|||
| Nicholas Global Equity and Income ETF | Index Risks [Member] | ||||
| Prospectus [Line Items] | ||||
| Risk [Text Block] | Index Risks: The Fund will be subject to varying risks depending on its then-current holdings. Differing risks may apply depending on the relevant Index’s composition. For U.S. Indices, economic and market conditions primarily drive performance, while sector-specific downturns can impact an Index. Global Indices are subject to geopolitical risks and unexpected events like pandemics, introducing volatility. Foreign Indices may be influenced by economic factors specific to those countries or regions.
|
|||
| Nicholas Global Equity and Income ETF | Options Contracts [Member] | ||||
| Prospectus [Line Items] | ||||
| Risk [Text Block] | Options Contracts. The use of options contracts involves investment strategies and risks different from those associated with ordinary portfolio securities transactions. The prices of options are volatile and are influenced by, among other things, actual and anticipated changes in the value of the underlying instrument, including the anticipated volatility, which are affected by fiscal and monetary policies and by national and international political, changes in the actual or implied volatility or the reference asset, the time remaining until the expiration of the option contract and economic events. For the Fund in particular, the value of the options contracts in which it invests are substantially influenced by the value of the Index. 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 at the underlying instrument. There may at times be an imperfect correlation between the movement in values options contracts and the underlying instrument, and there may at times not be a liquid secondary market for certain options contracts. The value of the options held by the Fund will be determined based on market quotations or other recognized pricing methods.
|
|||
| Nicholas Global Equity and Income ETF | Correlation Risks [Member] | ||||
| Prospectus [Line Items] | ||||
| Risk [Text Block] | Correlation Risks. The Fund’s portfolio will be comprised of various Index ETFs (or representative samplings of such Index ETFs), some of which will be tied to Indices different from those used for the Fund’s Index Covered Call Spreads. As a result, correlation between the performance of the Index ETFs (and representative samplings) and the targeted Indices for Fund’s Covered Call Spread strategies will likely deviate. That is the movements of the Index ETFs (and representative samplings) may not consistently align with those of the Indices targeted for Covered Call Spreads. This means that the Fund may not fully capture the gains from the underlying Indices targeted for Covered Call Spread strategies. For example, assume a specific Index is used for the Fund’s Covered Call Spreads, but the Fund does not hold a corresponding Index ETF for that particular Index. In this scenario, if the value of that Index increases, the Fund’s potential gains will be limited, and the performance of its other Index ETF holdings may not align with the appreciation of that specific Index.
|
|||
| Nicholas Global Equity and Income ETF | Foreign Investment Risk [Member] | ||||
| Prospectus [Line Items] | ||||
| Risk [Text Block] | Foreign Investment Risk. The Fund will invest in foreign securities, including non-U.S. dollar-denominated securities traded outside of the United States and U.S. dollar-denominated securities of foreign issuers traded in the United States. Returns on investments in foreign securities could be more volatile than, or trail the returns on, investments in U.S. securities. Investments in foreign securities, including investments in American Depositary Receipts (ADRs), European Depositary Receipts (EDRs) and Global Depositary Receipts (GDRs), are subject to special risks, including the following:

|
|||
| Nicholas Global Equity and Income ETF | Emerging Markets Risk [Member] | ||||
| Prospectus [Line Items] | ||||
| Risk [Text Block] | Emerging Markets Risk. The Fund may invest in companies in emerging markets. Emerging market countries generally have less established economies, smaller capital markets and greater social, economic, regulatory or political risks. These factors could contribute to increased volatility, liquidity risks and valuation risks. These risks apply to direct holdings in foreign companies and holdings in depository receipts for foreign companies.

| Nicholas Global Equity and 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 monthly income. There is no assurance that the Fund will make a distribution in any given month. If the Fund does make distributions, the amounts of such distributions will likely vary greatly from one distribution to the next. Additionally, the monthly distributions, if any, may consist of returns of capital, which would decrease the Fund’s NAV and trading price over time. As a result, an investor may suffer significant losses to their investment.

| Nicholas Global Equity and Income ETF | NAV Erosion Risk Due to Distributions [Member] | ||||
| Prospectus [Line Items] | ||||
| Risk [Text Block] | NAV Erosion Risk Due to Distributions. When the Fund makes a distribution, the Fund’s NAV will typically drop by the amount of the distribution on the related ex-dividend date. (i.e., the date by which you need to own a dividend-paying stock in order to receive the upcoming dividend payment). The repeated payment of distributions by the Fund, if any, may significantly erode the Fund’s NAV and trading price over time. As a result, an investor may suffer significant losses to their investment.

| 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.

| Nicholas Global Equity and Income ETF | Liquidity Risk [Member] | ||||
| Prospectus [Line Items] | ||||
| Risk [Text Block] | Liquidity Risk. Some securities held by the Fund, including options contracts, may be difficult to sell or be illiquid, particularly during times of market turmoil. Markets for securities or financial instruments could be disrupted by a number of events, including, but not limited to, an economic crisis, natural disasters, epidemics/pandemics, new legislation or regulatory changes inside or outside the United States. Illiquid securities may be difficult to value, especially in changing or volatile markets. If the Fund is forced to sell an illiquid security at an unfavorable time or price, the Fund may be adversely impacted. Certain market conditions or restrictions may prevent the Fund from limiting losses, realizing gains or achieving a high correlation with the Index. 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.

| Nicholas Global Equity and 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 (“RIC”) under Subchapter M of the Code. As a RIC, the Fund will not be subject to U.S. federal income tax on the portion of its net investment income and net capital gain that it distributes to Shareholders, provided that it satisfies certain requirements of the Code. If the Fund does not qualify as a RIC for any taxable year and certain relief provisions are not available, the Fund’s taxable income will be subject to tax at the Fund level and to a further tax at the shareholder level when such income is distributed. To comply with the asset diversification test applicable to a RIC, the Fund will attempt to ensure that the value of options it holds is never 25% of the total value of Fund assets at the close of any quarter. If the Fund’s investments in options 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] | 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. | |||
| Nicholas Global Equity and 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. This may increase a Fund’s volatility and cause the performance of a relatively smaller number of issuers to have a greater impact on the Fund’s performance.
