The Fund pays transaction costs, such as commissions, when it buys and sells securities (or “turns over” its portfolio). A higher portfolio turnover may indicate higher transaction costs. These costs, which are not reflected in annual Fund operating expenses or in the Example, affect the Fund’s performance. During the most recent fiscal year, the Fund’s portfolio turnover rate was 101% of the average value of its portfolio.

Strategy Narrative [Text Block]

rr_StrategyNarrativeTextBlock

The Fund’s investment adviser seeks to achieve the Fund’s primary investment objective by seeking to track the W.E. Donoghue Power Dividend Index (the “Power Dividend Index”) that provides a formulaic methodology for allocating investment between the S-Network Quality Sector Dividend Dogs Index (SNQDIV) and short-term treasuries (maturity of 1 year or less).

The methodology of the Power Dividend Index is designed to convey the benefits of high dividend yield, sector diversification and equal weighting. In seeking to track the Power Dividend Index, the adviser buys equity securities in the SNQDIV Index as described below when its indicators are positive and sells them when its indicators are significantly negative. Under normal circumstances, the Fund will invest at least 80% of its net assets in dividend producing equity securities. As described below, the Fund will invest in as many as 50 equity securities.

The SNQDIV Index selects as of November 30 of each year the top five companies with the highest ratio of free cash flow to debt from among the 10 companies with the highest dividend yields in each of 10 sectors (excluding Real Estate) of the S-Network US Equity Large/Mid-Cap 1000 Index. Free cash flow is the amount of cash a company produces after paying for operating and capital expenses. Only companies with positive free cash flow, at least one dividend paid during the previous four quarters, and meeting an average daily traded value minimum over the previous 90 days are eligible for inclusion in the SNQDIV Index. If there are fewer than five eligible securities represented in any sector as of the snapshot date, the SNQDIV Index will include only those securities that qualify. Under most circumstances, the Fund will invest at least 80% of its net assets in dividend producing securities. The Fund will invest in as many as 50 common stocks from the universe of stocks represented in the S-Network Large/Mid Cap 1000 Index. If the Fund holds an investment in common stock of a company that is removed from the S-Network Large/Mid Cap 1000 Index, that position will be sold.

This methodology is designed to convey the benefits of high dividend yield, sector diversification and equal weighting. The adviser then applies its defensive tactical overlay as described below to both its proprietary index, the W.E. Donoghue Power Dividend Index, and the Fund. The adviser buys equity securities when its indicators are positive and sells them when its indicators are significantly negative. From time to time, the Adviser anticipates that its defensive tactical overlay may trigger multiple “positive” or negative” indicators over a period of several days. In such cases, the Adviser, in an effort to avoid incurring additional brokerage costs to the Fund, may choose not to implement a particular “buy” or “sell” signal at the time of the trigger.

In following the Power Dividend Index’s methodology, the Fund will allocate its assets based on two separate indicators:

• Exponential Moving Average Indicator – The Fund will allocate 50% of its assets to short term treasuries or money market funds when a shorter-term exponential moving average value of the SNQDIV Index is less than a longer- term exponential moving average value of the SNQDIV Index over certain time periods. An index’s exponential moving average value is the weighted average of its value over a certain period of time (e.g. 50 days). An exponential moving average gives more weighting to more recent values for the relevant time period.

• NFCI Leverage Indicator – The Fund will also allocate 50% of its assets to short term treasuries or money market funds depending on the current value of the Nonfinancial Leverage Sub-Index as compared to its historical average. The Nonfinancial Leverage Sub-Index is a component of the National Financial Conditions Index (“NFCI”), an index which measures the financial condition of the U.S. based on conditions in money markets, debt and equity markets and banking systems. The Nonfinancial Leverage Sub-Index measures leverage conditions based on equity and debt levels.

For periods when both indicators are negative, the Fund will be fully invested in short-term treasury exchange-traded funds or treasury money market funds as a defensive measure.

Conversely, when either the Exponential Moving Average Indicator combined with Simple Moving Average confirmation indicators or NFCI Leverage Indicator is positive, the Fund will be fully invested in the components of the SNQDIV Index as described above. A simple moving average value is the average of an index’s value over a certain period of time and gives equal weighting to each value in the relevant time period.

From time to time, the adviser anticipates that its defensive tactical overlay may trigger multiple “positive” or negative” indicators over a period of several days. In such cases, the adviser, in an effort to avoid incurring additional brokerage costs to the Fund, may choose not to implement a particular “buy” or “sell” signal at the time of the trigger. Absent such circumstances, the Fund will not be actively managed and will seek to track the Power Dividend Index’s methodology.

The adviser seeks to achieve the Fund’s secondary investment objective by hedging the equity portfolio when its defensive tactical overlay determines a sell. The adviser hedges the portfolio by increasing allocations to cash equivalents or U.S. Treasury securities if the adviser determines the Fund should adopt a temporary defensive position due to market conditions. While the Fund is a diversified fund, it may invest in fewer securities that other diversified funds.

Accordingly, the Fund’s performance may be more sensitive to market changes than other diversified funds. In seeking to track the methodology of the Power Dividend Index, the Fund may engage in frequent buying and selling of portfolio securities resulting in a higher turnover rate.

Risk Narrative [Text Block]

rr_RiskNarrativeTextBlock

As with all mutual funds, there is the risk that you could lose money through your investment in the Fund. The Fund is not intended to be a complete investment program. Many factors affect the Fund’s net asset value and performance.

The following risks apply to the Fund:

• Credit Risk. There is a risk that issuers will not make payments on fixed income securities held by the Fund or an ETF in which the Fund invests, resulting in losses to the Fund. In addition, the credit quality of fixed income securities may be lowered if an issuer’s financial condition changes. The issuer of a fixed income security may also default on its obligations.

• Equity Risk. The net asset value of the Fund will fluctuate based on changes in the value of the equity securities in which it invests Equity prices can fall rapidly in response to developments affecting a specific company or industry, or to changing economic, political or market conditions.

• ETF and Mutual Fund Risk. ETFs and mutual funds are subject to investment advisory fees and other expenses, which will be indirectly paid by the Fund. As a result, your cost of investing in the Fund will be higher than the cost of investing directly in ETFs and other mutual funds and may be higher than other funds that invest directly in equity and fixed income securities. Each ETF and mutual fund is subject to specific risks, depending on the nature of the fund. ETF shares may trade at a discount to or a premium above net asset value if there is a limited market in such shares. ETFs and index-tracking mutual funds in which the Fund invests will not be able to replicate exactly the performance of the indices they track. ETFs are also subject to brokerage and other trading costs, which could result in greater expenses to the Fund.

• Hedging Risk. Hedging strategies may not perform as anticipated by the adviser and the Fund could suffer losses by hedging with underlying money market funds if stock prices do not decline.

• Index Construction Risk. The Power Dividend Index, and consequently the Fund, may not succeed in its objective and may not be optimal in its construction, causing losses to the Fund.

• Index Tracking Risk. Investment in the Fund should be made with the understanding that the securities in which the Fund invests will not be able to replicate exactly the performance of the index the Fund tracks because the total return generated by the securities will be reduced by transaction costs incurred in adjusting the actual balance of the securities. In addition, the securities in which the Fund invests will incur expenses not incurred by an index. Certain securities comprising the index tracked by the Fund may, from time to time, temporarily be unavailable, which may further impede the Fund’s ability to track an index.

• Interest Rate Risk. Interest rate risk is the risk that fixed income security prices overall, including the prices of securities held by the Fund or an ETF in which the Fund invests, will decline over short or even long periods of time due to rising interest rates. Bonds with longer maturities tend to be more sensitive to interest rates than bonds with shorter maturities.

• Large-Cap Risk. Large-cap companies may be unable to respond quickly to new competitive challenges, such as changes in technology and consumer tastes, and also may not be able to attain the high growth rate of successful smaller companies, especially during extended periods of economic expansion.

• Management Risk. The adviser’s decision to seek to follow an index’s methodology in managing the Fund’s portfolio may prove to be incorrect and may not produce the desired results. Because the Fund seeks to track an index, the Fund may forego certain attractive investment opportunities available to an actively managed fund. In following the index’s methodology, the Fund may hold fewer securities than other diversified funds. Accordingly, the Fund’s performance may be more sensitive to market changes than other diversified funds.

• Market and Geopolitical Risk. The increasing interconnectivity between global economies and financial markets increases the likelihood that events or conditions in one region or financial market may adversely impact issuers in a different country, region or financial market. Securities in the Fund’s portfolio may underperform due to inflation (or expectations for inflation), interest rates, global demand for particular products or resources, natural disasters, pandemics, epidemics, terrorism, regulatory events and governmental or quasi-governmental actions. The occurrence of global events similar to those in recent years may result in market volatility and may have long term effects on both the U.S. and global financial markets. The current novel coronavirus (COVID-19) global pandemic and the aggressive responses taken by many governments, including closing borders, restricting international and domestic travel, and the imposition of prolonged quarantines or similar restrictions, as well as the forced or voluntary closure of, or operational changes to, many retail and other businesses, has had negative impacts, and in many cases severe negative impacts, on markets worldwide. It is not known how long such impacts, or any future impacts of other significant events described above, will or would last, but there could be a prolonged period of global economic slowdown, which may impact your Fund investment.

• Small and Mid-Cap Risk. The value of a small or mid-capitalization company stocks may be subject to more abrupt or erratic market movements than those of larger, more established companies or the market averages in general.

• Turnover Risk. Higher portfolio turnover will result in higher transactional and brokerage costs, which can negatively impact Fund performance.

• Underlying Funds Risk. If short-term treasury ETFs or money market funds (“Underlying Funds”) are utilized, such Underlying Funds are subject to investment advisory and other expenses, which will be indirectly paid by the Fund. As a result, your cost of investing in the Fund will be higher than the cost of investing directly in Underlying Funds and may be higher than other mutual funds that do not invest in Underlying Funds. The Fund will only utilize short-term treasury exchange-traded funds and money market mutual funds when it is in a defensive

• U.S. Treasury Risk. The Fund has investment exposure to short-term U.S. Treasury securities through its investment in short-term treasury exchange-traded funds. All money market instruments, including U.S. Treasury obligations, can change in value in response to changes in interest rates, and a major change in rates could cause the share price to change. While U.S. Treasury obligations are backed by the full faith and credit of the U.S. government, an investment in the Fund is neither insured nor guaranteed by the Federal Deposit Insurance Corporation, U.S. government or any other government agency.

Strategy Narrative [Text Block]

rr_StrategyNarrativeTextBlock

The adviser seeks to achieve the Fund’s objectives by investing in equally-weighted stocks at the beginning of each quarter that produced the highest risk-adjusted returns for the previous calendar quarter from each of the ten sectors (REITS are excluded) that comprise the S-Network Large/Mid Cap 1000 Index. The Fund seeks to replicate the returns of the adviser’s proprietary W.E. Donoghue Power Momentum Index. The Fund is predicated upon and has entered a licensing agreement with S-Network US Equity Large/Mid Cap Sharpe Ratio Index (“SNSHRPX”) for the Power Momentum Index which tracks the SNSHRPX Index of 50 stocks (five from each of the ten sectors which comprise the S-Network Large/Mid Cap 1000 Index), as determined by the highest risk-adjusted returns from the previous quarter and will reconstitute and rebalance each calendar quarter thereafter. The adviser uses a total return variation of the SNSHRPX Index to signal investment into and out of these 50 common stocks. The Fund invests in common stocks from the universe of stocks represented in the S-Network Large/Mid Cap 1000 Index which are also constituents of the SNSHRPX Index. The SNSHRPX Index selects the five stocks in each of the ten sectors that make up the S-Network Large/Mid Cap 1000 Index that have the highest 90-day Sharpe ratio. Sharpe ratio is a measure of a stock’s risk-adjusted return. This methodology is designed to convey the benefits of risk-adjusted returns, sector diversification and equal weighting. The adviser then applies its defensive tactical overlay as described below to both its proprietary index, the W.E. Donoghue Power Momentum Index, and the Fund. The adviser buys equity securities when its indicators are positive and sells them when its indicators are significantly negative. If the Fund holds an investment in common stock of a company that is removed from the S-Network Large/Mid Cap 1000 Index, that position will be sold.

When the adviser’s defensive tactical overlay indicates a defensive position, the adviser will increase allocations to cash equivalents such as money market funds or U.S. Treasury securities in an attempt to mitigate market risk. Technical indicators are utilized on each sector individually to determine whether to be in a bullish or defensive posture.

The Fund has adopted a non-fundamental policy to invest at least 80% of its net assets in the constituent securities that make up the Power Momentum Index. While the Fund is a diversified fund, it may invest in fewer securities than other diversified funds.

The adviser may engage in frequent of the Fund’s portfolio, resulting in a higher portfolio turnover.

Risk Narrative [Text Block]

rr_RiskNarrativeTextBlock

As with all mutual funds, there is the risk that you could lose money through your investment in the Fund. The Fund is not intended to be a complete investment program. Many factors affect the Fund’s net asset value and performance.

The following risks apply to the Fund:

• Credit Risk. There is a risk that issuers will not make payments on fixed income securities held by the Fund or an ETF in which the Fund invests, resulting in losses to the Fund. In addition, the credit quality of fixed income securities may be lowered if an issuer’s financial condition changes. The issuer of a fixed income security may also default on its obligations.

Each ETF and mutual fund is subject to specific risks, depending on the nature of the fund. ETF shares may trade at a discount to or a premium above net asset value if there is a limited market in such shares. ETFs and index-tracking mutual funds in which the Fund invests will not be able to replicate exactly the performance of the indices they track. ETFs are also subject to brokerage and other trading costs, which could result in greater expenses to the Fund.

• Hedging Risk. The Index’s defensive positioning may not effectively reduce the Fund’s downside risk. Hedging strategies may not perform as anticipated by the adviser and the Fund could suffer losses by hedging with underlying money market funds, short-term Treasury funds or Treasury ETFs if stock prices do not decline.

• Index Construction Risk. The Power Momentum Index, and consequently the Fund, may not succeed in its objective and may not be optimal in its construction, causing losses to the Fund.

• Index Tracking Risk. Investment in the Fund should be made with the understanding that the securities in which the Fund invests will not be able to replicate exactly the performance of the index the Fund tracks because the total return generated by the securities will be reduced by transaction costs incurred in adjusting the actual balance of the securities.

• Interest Rate Risk. Interest rate risk is the risk that fixed income security prices overall, including the prices of securities held by the Fund or an ETF in which the Fund invests, will decline over short or even long periods of time due to rising interest rates. Bonds with longer maturities tend to be more sensitive to interest rates than bonds with shorter maturities.

• Management Risk. The adviser’s decision to seek to follow an index’s methodology in managing the Fund’s portfolio may prove to be incorrect and may not produce the desired results. Because the Fund seeks to track an index, the Fund may forego certain attractive investment opportunities available to an actively managed fund.

Securities in the Fund’s portfolio may underperform due to inflation (or expectations for inflation), interest rates, global demand for particular products or resources, natural disasters, pandemics, epidemics, terrorism, regulatory events and governmental or quasi-governmental actions.

It is not known how long such impacts, or any future impacts of other significant events described above, will or would last, but there could be a prolonged period of global economic slowdown, which may impact your Fund investment.

• Small and Mid-Cap Company Risk. The value of a small or mid-capitalization company stocks may be subject to more abrupt or erratic market movements than those of larger, more established companies or the market averages in general.

• Turnover Risk. Higher portfolio turnover will result in higher transactional and brokerage costs. A high portfolio turnover can potentially increase taxes, which can negatively impact Fund performance.

• Underlying Funds Risk. If money market funds (“Underlying Funds”) are utilized as cash equivalents, such Underlying Funds are subject to investment advisory and other expenses, which will be indirectly paid by the Fund. As a result, your cost of investing in the Fund will be higher than the cost of investing directly in Underlying Funds and may be higher than other mutual funds that do not invest in Underlying Funds. The Fund will only utilize money market funds when it is in a defensive position.

• U.S. Treasury Risk. The Fund has investment exposure to short-term U.S. Treasury securities through its investment in short-term treasury exchange-traded funds. All money market instruments, including U.S. Treasury obligations, can change in value in response to changes in interest rates, and a major change in rates could cause the share price to change. While U.S. Treasury obligations are backed by the full faith and credit of the U.S. government, an investment in the Fund is neither insured nor guaranteed by the Federal Deposit Insurance Corporation, U.S. government or any other government agency.
