Strategy [Heading] rr_StrategyHeading Principal Investment Strategies
Strategy Narrative [Text Block] rr_StrategyNarrativeTextBlock
The Fund is an actively-managed exchange-traded Fund (“ETF”) that invests primarily in equity securities of large capitalization companies, with a focus on value stocks. A value stock is the stock of a company whose stock price may not reflect the company’s intrinsic value, or that is temporarily out of favor. Under normal circumstances, the Fund will invest at least 80% of its net assets, plus borrowings for investment purposes, in the common stocks of large capitalization companies. These companies have market capitalizations in the range of companies in the Russell 1000® Value Index (the “Index”) at the time of purchase. As of September 30, 2021, the market capitalization of companies in the Index was $10 billion and greater.
In seeking to achieve the Fund’s investment objective, Princeton Fund Advisers, LLC (the “Adviser”), the Fund’s investment adviser, implements its alpha strategy to seek to identify investment opportunities in which the performance of a company’s stock will exceed that of the market over time. In selecting stocks for the Fund, the Adviser combines its investment expertise with big data analytics and powerful machine learning to seek to identify, evaluate, and create a portfolio consisting of a consensus of high conviction positions held by what the Adviser believes are top-performing, actively-managed large-cap value fund managers and certain funds managed by those managers. These funds are screened by various objective risk and return metrics, including historical monthly and annual performance, Sharpe ratios (a measure of risk adjusted return), upside and downside capture ratios (a measure of performance against the market when it is up and down, respectively), and performance drawdown (a measure of downside volatility). “Big data analytics” is the use of advanced analytic techniques to analyze and extract information from large and complex data sets. “High conviction positions” are those positions in which the identified managers are overweight in relation to their benchmarks. The Adviser utilizes big data analytics to replicate those funds’ holdings and identify high conviction positions. From this universe, the Adviser identifies consensus agreement on high conviction stocks across the mutual funds, using analytics to evaluate frequency of appearance
and magnitude of conviction. From this, the Adviser then selects stocks for the Fund, creating a portfolio consisting of those high conviction positions.
The Adviser may sell a security from the Fund’s portfolio if the security’s risk parameters outweigh its return opportunities, more attractive alternatives are identified, or specific events alter the security’s prospects. Under normal circumstances, the Fund’s portfolio will consist of approximately 50 issuers, but it may at times consist of more or less than 50 issuers, depending on the Adviser’s assessment of appropriate and attractive investment opportunities. The Fund may engage in active and frequent trading of portfolio securities in implementing its principal investment strategies.
The Fund is classified as a “non-diversified” investment company under the Investment Company Act of 1940, as amended (the “1940 Act”).
Risk [Heading] rr_RiskHeading Principal Investment Risks
Risk Narrative [Text Block] rr_RiskNarrativeTextBlock
The principal risks of investing in the Fund are summarized below. The principal risks are presented in alphabetical order to facilitate finding particular risks and comparing them with those of other funds. Each risk summarized below is considered a “principal risk” of investing in the Fund, regardless of the order in which it appears. As with any investment, there is a risk that you could lose all or a portion of your investment in the Fund. Some or all of these risks may adversely affect the Fund’s net asset value (“NAV”), trading price, yield, total return and/or ability to meet its objective. The following risks could affect the value of your investment in the Fund:
•Cybersecurity Risk. Cybersecurity incidents may allow an unauthorized party to gain access to Fund assets, customer data (including private shareholder information), or proprietary information, or cause the Fund, the Adviser, the Sub-Adviser and/or other service providers (including custodians, transfer agents and financial intermediaries) to suffer data breaches or data corruption. Additionally, cybersecurity failures or breaches of the electronic systems of the Fund, the Adviser, the Sub-Adviser or the Fund's other service providers, market makers, Authorized Participants or the issuers of securities in which the Fund invests have the ability to cause disruptions and negatively impact the Fund's business operations, potentially resulting in financial losses to the Fund and its shareholders. In an extreme case, a shareholder’s ability to redeem Fund shares may be affected.
•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, sectors or companies in which the Fund invests. Common stocks are generally exposed to greater risk than other types of securities, such as preferred stocks and debt obligations, because common stockholders generally have inferior rights to receive payment from issuers.
•ETF Risks. The Fund is an ETF, and, as a result of its structure, it is exposed to the following risks:
◦Authorized Participants, Market Makers, and Liquidity Providers Concentration Risk. The Fund has a limited number of financial institutions that may act as Authorized Participants (“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.
◦Costs of Buying or Selling Shares. Due to the costs of buying or selling Shares, including brokerage commissions imposed by brokers and bid/ask spreads, frequent trading of Shares may significantly reduce investment results and an investment in Shares may not be advisable for investors who anticipate regularly making small investments.
◦Shares May Trade at Prices Other Than NAV. As with all ETFs, Shares may be bought and sold in the secondary market at market prices. Although it is expected that the market price of Shares will approximate the Fund’s NAV, there may be times when the market price of Shares is more than the NAV intra-day (premium) or less than the NAV intra-day (discount) due to supply and demand of Shares or during periods of market volatility. This risk is heightened in times of market volatility, periods of steep market declines, and periods when there is limited trading activity for Shares in the secondary market, in which case such premiums or discounts may be significant. Because securities held by the Fund may trade on foreign exchanges that are closed when the Fund’s primary listing exchange is open, the Fund is likely to experience premiums or discounts greater than those of domestic ETFs.
◦Trading. Although Shares are listed for trading on the NYSE Arca, Inc. (the “Exchange”) and may be traded on U.S. exchanges other than the Exchange, there can be no assurance that Shares will trade with any volume, or at all, on any stock exchange. In stressed market conditions, the market for Shares may become less liquid in response to deteriorating liquidity in the markets for the Fund’s underlying portfolio holdings. This adverse effect on liquidity for the Shares could in turn lead to differences between the market price of the Shares and the underlying value of those shares.
•Large Capitalization Risk. The Fund’s investments in large capitalization companies may underperform other segments of the market because large capitalization companies may be unable to respond quickly to new competitive challenges, such as changes
in technology and consumer tastes, and may not be able to attain the high growth rate of successful smaller companies, especially during extended periods of economic expansion.
•Management Risk. The Fund is actively managed and may not meet its investment objective based on the Adviser’s success or failure to implement investment strategies for the Fund.
•Market Risk. The trading prices of securities and other instruments fluctuate in response to a variety of factors. These factors include events impacting the entire market or specific market segments, such as political, market and economic developments, as well as events that impact specific issuers. The Fund’s NAV and market price, like security and commodity prices generally, may fluctuate significantly in response to these and other factors. As a result, an investor could lose money over short or long periods of time. Beginning in the first quarter of 2020, financial markets in the United States and around the world experienced extreme and in many cases unprecedented volatility and severe losses due to the COVID-19 pandemic. It is unknown how long circumstances related to the pandemic will persist, whether they will reoccur in the future, whether efforts to support the economy and financial markets will be successful, and what additional implications may follow from the pandemic. The impact of these events and other epidemics or pandemics in the future could adversely affect Fund performance.
•Models and Data Risk. The Adviser may rely on proprietary models and analysis (“Models and Data”) to make decisions about which securities to purchase or sell or the timing of such transactions. If Models and Data prove to be incorrect or incomplete, any decisions made in reliance thereon expose the Fund to potential risks. Some of the models used to construct the Fund are predictive in nature. The use of predictive models has inherent risks. For example, such models may incorrectly forecast future behavior, leading to potential losses. In addition, in unforeseen or certain low-probability scenarios (often involving a market disruption of some kind), such models may produce unexpected results, which can result in losses for the Fund. Furthermore, because predictive models are usually constructed based on historical data supplied by third parties, the success of relying on such models may depend heavily on the accuracy and reliability of the supplied historical data.
•New Fund Risk. The Fund is a recently organized investment company with no operating history. As a result, prospective investors have no track record or history on which to base their investment decision.
•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 lesser number of issuers than if it was a diversified fund. As a result, the Fund may be more exposed to the risks associated with and developments affecting an individual issuer or a lesser number of issuers than a fund that invests more widely. This may increase the Fund’s volatility and cause the performance of a relatively small number of issuers to have a greater impact on the Fund’s performance.
•Portfolio Turnover Risk. Because the Fund may “turn over” some or all of its portfolio frequently, the Fund may incur high levels of transaction costs, performance that is lower than expected and potentially greater tax exposure.
•Value Investing Risk. Because the Fund may utilize a value style of investing, the Fund could suffer losses or produce poor results relative to other funds, even in a rising market, if the Adviser’s assessment of a company’s value or prospects for exceeding earnings expectations or market conditions is incorrect.
Risk Lose Money [Text] rr_RiskLoseMoney As with any investment, there is a risk that you could lose all or a portion of your investment in the Fund.
Risk Nondiversified Status [Text] rr_RiskNondiversifiedStatus Because the Fund is “non-diversified,” it may invest a greater percentage of its assets in the securities of a single issuer or a lesser number of issuers than if it was a diversified fund. As a result, the Fund may be more exposed to the risks associated with and developments affecting an individual issuer or a lesser number of issuers than a fund that invests more widely. This may increase the Fund’s volatility and cause the performance of a relatively small number of issuers to have a greater impact on the Fund’s performance.

The Fund is an actively-managed exchange-traded Fund (“ETF”) that invests primarily in equity securities of large capitalization companies, with a focus on growth potential. A growth stock is the stock of a company that generates substantial and sustainable positive cash flow and whose revenues and earnings are expected to increase at a faster rate than the average company within the same industry. Under normal circumstances, the Fund will invest at least 80% of its net assets, plus borrowings for investment purposes, in the common stock of large capitalization companies. These companies have market capitalizations in the range of companies in the Russell 1000® Growth Index (the “Index”) at the time of purchase.

This adverse effect on liquidity for the Shares could in turn lead to differences between the market price of the Shares and the underlying value of those shares.
•Growth Investing Risk. Growth stocks can be volatile for several reasons. Since those companies usually invest a high portion of earnings in their businesses, they may lack the dividends of value stocks that can cushion stock prices in a falling market. The prices of growth stocks are based largely on projections of the issuer’s future earnings and revenues. If a company’s earnings or revenues fall short of expectations, its stock price may fall dramatically.
•Large Capitalization Risk. The Fund’s investments in large capitalization companies may underperform other segments of the market because large capitalization companies may be unable to respond quickly to new competitive challenges, such as changes in technology and consumer tastes, and may not be able to attain the high growth rate of successful smaller companies, especially during extended periods of economic expansion.

From this, the Adviser then selects stocks for the Fund, creating a portfolio consisting of those high conviction positions.
The Adviser may sell a security from the Fund’s portfolio if the security’s risk parameters outweigh its return opportunities, more attractive alternatives are identified, or specific events alter the security’s prospects. Under normal circumstances, the Fund’s portfolio will consist of approximately 50 issuers, but it may at times consist of more or less than 50 issuers, depending on the Adviser’s assessment of appropriate and attractive investment opportunities. The Fund may engage in active and frequent trading of portfolio securities in implementing its principal investment strategies. The Fund is classified as a “non-diversified” investment company under the Investment Company Act of 1940, as amended (the “1940 Act”).

Risk Narrative [Text Block] rr_RiskNarrativeTextBlock
The principal risks of investing in the Fund are summarized below. The principal risks are presented in alphabetical order to facilitate finding particular risks and comparing them with those of other funds. Each risk summarized below is considered a “principal risk” of investing in the Fund, regardless of the order in which it appears. As with any investment, there is a risk that you could lose all or a portion of your investment in the Fund. Some or all of these risks may adversely affect the Fund’s net asset value (“NAV”), trading price, yield, total return and/or ability to meet its objective. The following risks could affect the value of your investment in the Fund:
•Cybersecurity Risk. Cybersecurity incidents may allow an unauthorized party to gain access to Fund assets, customer data (including private shareholder information), or proprietary information, or cause the Fund, the Adviser, the Sub-Adviser and/or other service providers (including custodians, transfer agents and financial intermediaries) to suffer data breaches or data corruption. Additionally, cybersecurity failures or breaches of the electronic systems of the Fund, the Adviser, the Sub-Adviser or the Fund's other service providers, market makers, Authorized Participants or the issuers of securities in which the Fund invests have the ability to cause disruptions and negatively impact the Fund's business operations, potentially resulting in financial losses to the Fund and its shareholders. In an extreme case, a shareholder’s ability to redeem Fund shares may be affected.
•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, sectors or companies in which the Fund invests. Common stocks are generally exposed to greater risk than other types of securities, such as preferred stocks and debt obligations, because common stockholders generally have inferior rights to receive payment from issuers.
•ETF Risks. The Fund is an ETF, and, as a result of its structure, it is exposed to the following risks:
◦Authorized Participants, Market Makers, and Liquidity Providers Concentration Risk. The Fund has a limited number of financial institutions that may act as Authorized Participants (“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.
◦Costs of Buying or Selling Shares. Due to the costs of buying or selling Shares, including brokerage commissions imposed by brokers and bid/ask spreads, frequent trading of Shares may significantly reduce investment results and an investment in Shares may not be advisable for investors who anticipate regularly making small investments.
◦Shares May Trade at Prices Other Than NAV. As with all ETFs, Shares may be bought and sold in the secondary market at market prices. Although it is expected that the market price of Shares will approximate the Fund’s NAV, there may be times when the market price of Shares is more than the NAV intra-day (premium) or less than the NAV intra-day (discount) due to supply and demand of Shares or during periods of market volatility. This risk is heightened in times of market volatility, periods of steep market declines, and periods when there is limited trading activity for Shares in the secondary market, in which case such premiums or discounts may be significant. Because securities held by the Fund may trade on foreign exchanges that are closed when the Fund’s primary listing exchange is open, the Fund is likely to experience premiums or discounts greater than those of domestic ETFs.
◦Trading. Although Shares are listed for trading on the NYSE Arca, Inc. (the “Exchange”) and may be traded on U.S. exchanges other than the Exchange, there can be no assurance that Shares will trade with any volume, or at all, on any stock exchange. In stressed market conditions, the market for Shares may become less liquid in response to deteriorating liquidity in the markets for the Fund’s underlying portfolio holdings. This adverse effect on liquidity for the Shares could in turn lead to differences between the market price of the Shares and the underlying value of those shares.
•Management Risk. The Fund is actively managed and may not meet its investment objective based on the Adviser’s success or failure to implement investment strategies for the Fund.
•Market Risk. The trading prices of securities and other instruments fluctuate in response to a variety of factors. These factors include events impacting the entire market or specific market segments, such as political, market and economic developments, as
well as events that impact specific issuers. The Fund’s NAV and market price, like security and commodity prices generally, may fluctuate significantly in response to these and other factors. As a result, an investor could lose money over short or long periods of time. Beginning in the first quarter of 2020, financial markets in the United States and around the world experienced extreme and in many cases unprecedented volatility and severe losses due to the COVID-19 pandemic. It is unknown how long circumstances related to the pandemic will persist, whether they will reoccur in the future, whether efforts to support the economy and financial markets will be successful, and what additional implications may follow from the pandemic. The impact of these events and other epidemics or pandemics in the future could adversely affect Fund performance.
•Mid-Capitalization Risk. The securities of mid-capitalization companies may be more vulnerable to adverse issuer, market, political, or economic developments than securities of large-capitalization companies. The securities of mid-capitalization companies generally trade in lower volumes and are subject to greater and more unpredictable price changes than large capitalization stocks or the stock market as a whole.
•Models and Data Risk. The Adviser may rely on proprietary models and analysis (“Models and Data”) to make decisions about which securities to purchase or sell or the timing of such transactions. If Models and Data prove to be incorrect or incomplete, any decisions made in reliance thereon expose the Fund to potential risks. Some of the models used to construct the Fund are predictive in nature. The use of predictive models has inherent risks. For example, such models may incorrectly forecast future behavior, leading to potential losses. In addition, in unforeseen or certain low-probability scenarios (often involving a market disruption of some kind), such models may produce unexpected results, which can result in losses for the Fund. Furthermore, because predictive models are usually constructed based on historical data supplied by third parties, the success of relying on such models may depend heavily on the accuracy and reliability of the supplied historical data.
•New Fund Risk. The Fund is a recently organized investment company with no operating history. As a result, prospective investors have no track record or history on which to base their investment decision.
•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 lesser number of issuers than if it was a diversified fund. As a result, the Fund may be more exposed to the risks associated with and developments affecting an individual issuer or a lesser number of issuers than a fund that invests more widely. This may increase the Fund’s volatility and cause the performance of a relatively small number of issuers to have a greater impact on the Fund’s performance.
•Portfolio Turnover Risk. Because the Fund may “turn over” some or all of its portfolio frequently, the Fund may incur high levels of transaction costs, performance that is lower than expected and potentially greater tax exposure.
•Value Investing Risk. Because the Fund may utilize a value style of investing, the Fund could suffer losses or produce poor results relative to other funds, even in a rising market, if the Adviser’s assessment of a company’s value or prospects for exceeding earnings expectations or market conditions is incorrect.

Strategy Narrative [Text Block] rr_StrategyNarrativeTextBlock
The Fund is an actively-managed exchange-traded Fund (“ETF”) that invests primarily in equity securities of mid-capitalization companies, with a focus on growth potential. A growth stock is the stock of a company that generates substantial and sustainable positive cash flow and whose revenues and earnings are expected to increase at a faster rate than the average company within the same industry. Under normal circumstances, the Fund will invest at least 80% of its net assets, plus borrowings for investment purposes, in common stock of mid-capitalization companies. These companies have market capitalizations in the range of companies in the Russell Midcap® Growth Index (the “Index”) at the time of purchase. As of September 30, 2021, the market capitalization of companies in the Index ranged between $2 billion and $10 billion.
In seeking to achieve the Fund’s investment objective, Princeton Fund Advisers, LLC (the “Adviser”), the Fund’s investment adviser, implements its alpha strategy to seek to identify investment opportunities in which the performance of a company’s stock will exceed that of the market over time. In selecting stocks for the Fund, the Adviser combines its investment expertise with big data analytics and powerful machine learning to seek to identify, evaluate, and create a portfolio consisting of a consensus of high conviction positions held by what the Adviser believes are top-performing, actively-managed mid-cap growth fund managers and certain funds managed by those managers. These funds are screened by various objective risk and return metrics, including historical monthly and annual performance, Sharpe ratios (a measure of risk adjusted return), upside and downside capture ratios (a measure of performance against the market when it is up and down, respectively), and performance drawdown (a measure of downside volatility). “Big data analytics” is the use of advanced analytic techniques to analyze and extract information from large and complex data sets. “High conviction positions” are those positions in which the identified managers are overweight in relation to their benchmarks. The Adviser utilizes big data analytics to replicate those funds’ holdings and identify high conviction positions. From this universe, the Adviser identifies consensus agreement on high conviction stocks across the mutual funds, using analytics to evaluate frequency of appearance and magnitude of conviction. From this, the Adviser then selects stocks for the Fund, creating a portfolio consisting of those high conviction positions.
The Adviser may sell a security from the Fund’s portfolio if the security’s risk parameters outweigh its return opportunities, more attractive alternatives are identified, or specific events alter the security’s prospects. Under normal circumstances, the Fund’s portfolio will consist of approximately 50 issuers, but it may at times consist of more or less than 50 issuers, depending on the Adviser’s assessment of appropriate and attractive investment opportunities. The Fund may engage in active and frequent trading of portfolio securities in implementing its principal investment strategies. The Fund is classified as a “non-diversified” investment company under the Investment Company Act of 1940, as amended (the “1940 Act”).

Each risk summarized below is considered a “principal risk” of investing in the Fund, regardless of the order in which it appears. As with any investment, there is a risk that you could lose all or a portion of your investment in the Fund. Some or all of these risks may adversely affect the Fund’s net asset value (“NAV”), trading price, yield, total return and/or ability to meet its objective. The following risks could affect the value of your investment in the Fund:
•Cybersecurity Risk. Cybersecurity incidents may allow an unauthorized party to gain access to Fund assets, customer data (including private shareholder information), or proprietary information, or cause the Fund, the Adviser, the Sub-Adviser and/or other service providers (including custodians, transfer agents and financial intermediaries) to suffer data breaches or data corruption.

This adverse effect on liquidity for the Shares could in turn lead to differences between the market price of the Shares and the underlying value of those shares.
•Growth Investing Risk. Growth stocks can be volatile for several reasons. Since those companies usually invest a high portion of earnings in their businesses, they may lack the dividends of value stocks that can cushion stock prices in a falling market. The prices of growth stocks are based largely on projections of the issuer’s future earnings and revenues. If a company’s earnings or revenues fall short of expectations, its stock price may fall dramatically.
•Management Risk. The Fund is actively managed and may not meet its investment objective based on the Adviser’s success or failure to implement investment strategies for the Fund.

Because securities held by the Fund may trade on foreign exchanges that are closed when the Fund’s primary listing exchange is open, the Fund is likely to experience premiums or discounts greater than those of domestic ETFs.
◦Trading. Although Shares are listed for trading on the NYSE Arca, Inc. (the “Exchange”) and may be traded on U.S. exchanges other than the Exchange, there can be no assurance that Shares will trade with any volume, or at all, on any stock exchange. In stressed market conditions, the market for Shares may become less liquid in response to deteriorating liquidity in the markets for the Fund’s underlying portfolio holdings. This adverse effect on liquidity for the Shares could in turn lead to differences between the market price of the Shares and the underlying value of those shares.
•Management Risk. The Fund is actively managed and may not meet its investment objective based on the Adviser’s success or failure to implement investment strategies for the Fund.
•Market Risk. The trading prices of securities and other instruments fluctuate in response to a variety of factors. These factors include events impacting the entire market or specific market segments, such as political, market and economic developments, as
well as events that impact specific issuers. The Fund’s NAV and market price, like security and commodity prices generally, may fluctuate significantly in response to these and other factors. As a result, an investor could lose money over short or long periods of time. Beginning in the first quarter of 2020, financial markets in the United States and around the world experienced extreme and in many cases unprecedented volatility and severe losses due to the COVID-19 pandemic. It is unknown how long circumstances related to the pandemic will persist, whether they will reoccur in the future, whether efforts to support the economy and financial markets will be successful, and what additional implications may follow from the pandemic. The impact of these events and other epidemics or pandemics in the future could adversely affect Fund performance.
•Models and Data Risk. The Adviser may rely on proprietary models and analysis (“Models and Data”) to make decisions about which securities to purchase or sell or the timing of such transactions. If Models and Data prove to be incorrect or incomplete, any decisions made in reliance thereon expose the Fund to potential risks. Some of the models used to construct the Fund are predictive in nature. The use of predictive models has inherent risks. For example, such models may incorrectly forecast future behavior, leading to potential losses. In addition, in unforeseen or certain low-probability scenarios (often involving a market disruption of some kind), such models may produce unexpected results, which can result in losses for the Fund. Furthermore, because predictive models are usually constructed based on historical data supplied by third parties, the success of relying on such models may depend heavily on the accuracy and reliability of the supplied historical data.
•New Fund Risk. The Fund is a recently organized investment company with no operating history. As a result, prospective investors have no track record or history on which to base their investment decision.
•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 lesser number of issuers than if it was a diversified fund. As a result, the Fund may be more exposed to the risks associated with and developments affecting an individual issuer or a lesser number of issuers than a fund that invests more widely. This may increase the Fund’s volatility and cause the performance of a relatively small number of issuers to have a greater impact on the Fund’s performance.
•Portfolio Turnover Risk. Because the Fund may “turn over” some or all of its portfolio frequently, the Fund may incur high levels of transaction costs, performance that is lower than expected and potentially greater tax exposure.
•Small-Capitalization Risk. The securities of small-capitalization companies may be more vulnerable to adverse issuer, market, political, or economic developments than securities of large- or mid-capitalization companies. The securities of small-capitalization companies generally trade in lower volumes and are subject to greater and more unpredictable price changes than large- or mid-capitalization stocks or the stock market as a whole. There is typically less publicly available information concerning smaller-capitalization companies than for larger, more established companies.
•Value Investing Risk. Because the Fund may utilize a value style of investing, the Fund could suffer losses or produce poor results relative to other funds, even in a rising market, if the Adviser’s assessment of a company’s value or prospects for exceeding earnings expectations or market conditions is incorrect.

Strategy [Heading] rr_StrategyHeading Principal Investment Strategies
Strategy Narrative [Text Block] rr_StrategyNarrativeTextBlock
The Fund is an actively-managed exchange-traded Fund (“ETF”) that invests primarily in equity securities of small capitalization companies, with a focus on growth potential. A growth stock is the stock of a company that generates substantial and sustainable positive cash flow and whose revenues and earnings are expected to increase at a faster rate than the average company within the same industry. Under normal circumstances, the Fund will invest at least 80% of its net assets in common stocks of small capitalization companies. These companies have market capitalizations in the range of companies in the Russell 2000® Growth Index (the “Index”) at the time of purchase. As of September 30, 2021, the market capitalization of companies in the Index ranged between $300 million and $2 billion.
In seeking to achieve the Fund’s investment objective, Princeton Fund Advisers, LLC (the “Adviser”), the Fund’s investment adviser, implements its alpha strategy to seek to identify investment opportunities in which the performance of a company’s stock will exceed that of the market over time. In selecting stocks for the Fund, the Adviser combines its investment expertise with big data analytics and powerful machine learning to seek to identify, evaluate, and create a portfolio consisting of a consensus of high conviction positions held by what the Adviser believes are top-performing, actively-managed small-cap growth fund managers and certain funds managed by those managers. These funds are screened by various objective risk and return metrics, including historical monthly and annual performance, Sharpe ratios (a measure of risk adjusted return), upside and downside capture ratios (a measure of performance against the market when it is up and down, respectively), and performance drawdown (a measure of downside volatility). “Big data analytics” is the use of advanced analytic techniques to analyze and extract information from large and complex data sets. “High conviction positions” are those positions in which the identified managers are overweight in relation to their benchmarks. The Adviser utilizes big data analytics to replicate those funds’ holdings and identify high conviction positions. From this universe, the Adviser identifies consensus agreement on high conviction stocks across the mutual funds, using analytics to evaluate frequency of appearance and magnitude of conviction. From this, the Adviser then selects stocks for the Fund, creating a portfolio consisting of those high conviction positions.
The Adviser may sell a security from the Fund’s portfolio if the security’s risk parameters outweigh its return opportunities, more attractive alternatives are identified, or specific events alter the security’s prospects. Under normal circumstances, the Fund’s portfolio will consist of approximately 50 issuers, but it may at times consist of more or less than 50 issuers, depending on the Adviser’s assessment of appropriate and attractive investment opportunities. The Fund may engage in active and frequent trading of portfolio securities in implementing its principal investment strategies. The Fund is classified as a “non-diversified” investment company under the Investment Company Act of 1940, as amended (the “1940 Act”).
Risk [Heading] rr_RiskHeading Principal Investment Risks
Risk Narrative [Text Block] rr_RiskNarrativeTextBlock
The principal risks of investing in the Fund are summarized below. The principal risks are presented in alphabetical order to facilitate finding particular risks and comparing them with those of other funds. Each risk summarized below is considered a “principal risk” of investing in the Fund, regardless of the order in which it appears. As with any investment, there is a risk that you could lose all or a portion of your investment in the Fund. Some or all of these risks may adversely affect the Fund’s net asset value (“NAV”), trading price, yield, total return and/or ability to meet its objective. The following risks could affect the value of your investment in the Fund:
•Cybersecurity Risk. Cybersecurity incidents may allow an unauthorized party to gain access to Fund assets, customer data (including private shareholder information), or proprietary information, or cause the Fund, the Adviser, the Sub-Adviser and/or other service providers (including custodians, transfer agents and financial intermediaries) to suffer data breaches or data corruption. Additionally, cybersecurity failures or breaches of the electronic systems of the Fund, the Adviser, the Sub-Adviser or the Fund's other service providers, market makers, Authorized Participants or the issuers of securities in which the Fund invests have the ability to cause disruptions and negatively impact the Fund's business operations, potentially resulting in financial losses to the Fund and its shareholders. In an extreme case, a shareholder’s ability to redeem Fund shares may be affected.
•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, sectors or companies in which the Fund invests. Common stocks are generally exposed to greater risk than other types of securities, such as preferred stocks and debt obligations, because common stockholders generally have inferior rights to receive payment from issuers.
•ETF Risks. The Fund is an ETF, and, as a result of its structure, it is exposed to the following risks:
◦Authorized Participants, Market Makers, and Liquidity Providers Concentration Risk. The Fund has a limited number of financial institutions that may act as Authorized Participants (“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.
◦Costs of Buying or Selling Shares. Due to the costs of buying or selling Shares, including brokerage commissions imposed by brokers and bid/ask spreads, frequent trading of Shares may significantly reduce investment results and an investment in Shares may not be advisable for investors who anticipate regularly making small investments.
◦Shares May Trade at Prices Other Than NAV. As with all ETFs, Shares may be bought and sold in the secondary market at market prices. Although it is expected that the market price of Shares will approximate the Fund’s NAV, there may be times when the market price of Shares is more than the NAV intra-day (premium) or less than the NAV intra-day (discount) due to supply and demand of Shares or during periods of market volatility. This risk is heightened in times of market volatility, periods of steep market declines, and periods when there is limited trading activity for Shares in the secondary market, in which case such premiums or discounts may be significant. Because securities held by the Fund may trade on foreign exchanges that are closed when the Fund’s primary listing exchange is open, the Fund is likely to experience premiums or discounts greater than those of domestic ETFs.
◦Trading. Although Shares are listed for trading on the NYSE Arca, Inc. (the “Exchange”) and may be traded on U.S. exchanges other than the Exchange, there can be no assurance that Shares will trade with any volume, or at all, on any stock exchange. In stressed market conditions, the market for Shares may become less liquid in response to deteriorating liquidity in the markets for the Fund’s underlying portfolio holdings. This adverse effect on liquidity for the Shares could in turn lead to differences between the market price of the Shares and the underlying value of those shares.
•Growth Investing Risk. Growth stocks can be volatile for several reasons. Since those companies usually invest a high portion of earnings in their businesses, they may lack the dividends of value stocks that can cushion stock prices in a falling market. The prices of growth stocks are based largely on projections of the issuer’s future earnings and revenues. If a company’s earnings or revenues fall short of expectations, its stock price may fall dramatically.
•Management Risk. The Fund is actively managed and may not meet its investment objective based on the Adviser’s success or failure to implement investment strategies for the Fund.
•Market Risk. The trading prices of securities and other instruments fluctuate in response to a variety of factors. These factors include events impacting the entire market or specific market segments, such as political, market and economic developments, as well as events that impact specific issuers. The Fund’s NAV and market price, like security and commodity prices generally, may fluctuate significantly in response to these and other factors. As a result, an investor could lose money over short or long periods of time.
