This table describes the fees and expenses that you may pay if you buy, hold, and sell shares of the Fund. You may pay other fees, such as brokerage commissions and other fees to financial intermediaries, which are not reflected in the tables and example below. You may qualify for sales charge discounts if you and your family invest, or agree to invest in the future, at least $50,000 in the Fund or another series of the Trust managed by Olstein Capital Management, L.P. (“OCM” or the “Adviser”). Sales load waivers may vary by financial intermediary. For more information on specific financial intermediary sales loads and waivers, see Appendix A to the statutory Prospectus. More information about these and other discounts is available from your financial adviser and in the Prospectus under the section titled, “Shareholder Information – Class Descriptions” on page 35 of the Fund’s statutory Prospectus. The table below does not reflect any transaction fees that may be charged by a financial intermediary or commissions that a shareholder may be required to pay directly to its financial intermediary when buying and selling Adviser Class shares.

The Fund pays transaction costs, such as commissions, when it buys and sells securities (or “turns over” its portfolio). A higher portfolio turnover rate may indicate higher transaction costs and may result in higher taxes when Fund shares are held in a taxable account. These costs, which are not reflected in the annual fund operating expenses or in the Example, affect the Fund’s performance. During the most recent fiscal year ended June 30, 2024, the Fund's portfolio turnover rate was approximately 27% of the average value of its portfolio.

Strategy [Heading] rr_StrategyHeading Principal Investment Strategies
Strategy Narrative [Text Block] rr_StrategyNarrativeTextBlock
The Fund seeks to achieve its objectives by investing primarily in a diversified portfolio of common stocks that the Fund’s investment adviser, Olstein Capital Management, L.P. (“OCM”), believes are significantly undervalued. OCM follows an accounting-driven, value-oriented approach that emphasizes looking behind the numbers of financial statements based on the belief that the price of a common stock may not reflect the intrinsic value of the issuing company’s underlying business. The Fund uses several valuation methods to determine private market value, all of which emphasize expected future free cash flow. Future free cash flow represents the cash that a company is able to generate from operations after any required investment to maintain or expand its asset base (i.e., after required capital expenditures and working capital needs).
When evaluating the value of stocks for the Fund, OCM undertakes an in-depth analysis of financial statements, as it seeks to identify early signs of potential changes in a company’s ability to generate sustainable free cash flow as well as its potential to grow that may not be recognized by the financial markets. When determining sustainable free cash flow and the quality of earnings, OCM assesses the accounting practices and assumptions used to construct financial statements against the economic reality of the company’s business. OCM believes that in-depth analysis of financial statements reveals the success of a company’s strategy, the sustainability of its performance and the impact of management decisions on future cash flow. OCM further believes that such an analysis is more useful to an investor than management forecasts or earnings guidance.
OCM believes stock prices often fall below a company’s private market value as a result of a short-term focus on, or an overreaction to, negative information regarding the company or its industry, or negative overall market psychology. The Fund seeks to capitalize on market volatility and the valuation extremes specific to a company by purchasing its stock at a discount to OCM’s estimate of private market value, which could result in above-average capital appreciation if such discount is corrected by market forces or other catalysts that change perceptions.
The Fund’s bottom-up analysis seeks to identify companies with unique business fundamentals and a competitive edge, which usually provide a greater predictability of future free cash flow. Companies with free cash flow have the potential to enhance shareholder value by increasing dividends, repurchasing shares, reducing debt, engaging in strategic acquisitions, withstanding an economic downturn without adopting harmful short-term strategies or being an attractive acquisition target.
The Fund will invest in companies without regard to whether they are conventionally categorized as small, medium, or large capitalization or whether they are characterized as growth, value, cyclical, or
any other category. OCM’s assessment of a company’s intrinsic value relative to its market price is the key determinant influencing all investment decisions. The Fund may invest up to 20% of its net assets in foreign securities that are traded in U.S. dollars, including American Depositary Receipts ("ADRs") and will limit the Fund’s foreign investments to investments in developed countries, rather than countries with developing or emerging markets.

Risk [Text Block] rr_RiskTextBlock General Market Risk. The Fund’s net asset value ("NAV") and investment return will fluctuate based upon changes in the value of its portfolio securities. Certain securities selected for the Fund’s portfolio may be worth less than the price originally paid for them, or less than they were worth at an earlier time.
Olstein All Cap Value Fund | Management Risk Member

Risk [Text Block] rr_RiskTextBlock
Equity Securities 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 industries, sectors, geographic markets or companies in which the Fund invests.
Olstein All Cap Value Fund | Small- And Mid-Sized Company Risk Member  
Prospectus [Line Items] rr_ProspectusLineItems  
Risk [Text Block] rr_RiskTextBlock
Small- and Mid-Sized Company Risk. Small- and mid-sized companies may be more vulnerable to adverse business or economic events than larger, more established companies. In particular, these companies may have an unproven or narrow technological base and limited product lines, distribution channels, and market and financial resources, and small capitalization companies also may be dependent on entrepreneurial management, making the companies more susceptible to certain setbacks and reversals.
Olstein All Cap Value Fund | Value-Style Investing Risk Member  
Prospectus [Line Items] rr_ProspectusLineItems  
Risk [Text Block] rr_RiskTextBlock
Value-Style Investing Risk. The Fund uses a value-oriented investment approach. However, a particular value stock may not increase in price as anticipated by OCM (and may actually decline in price) if other investors fail to recognize the stock’s value or if a catalyst that OCM believes will increase the price of the stock does not occur or does not affect the price of the stock in the manner or to the degree anticipated.
Olstein All Cap Value Fund | Foreign Investing Risk Member  
Prospectus [Line Items] rr_ProspectusLineItems  
Risk [Text Block] rr_RiskTextBlock
Foreign Investing Risk. Investing in foreign companies typically involves more risks than investing in U.S. companies. These risks can increase the potential for losses in the Fund and may include risks related to currency exchange rate fluctuations, country or government specific issues (for example, terrorism, war, social and economic instability, currency devaluations, and restrictions on foreign investment or the movement of assets), unfavorable trading practices, less government supervision, less publicly available information, limited trading markets and greater volatility. There may be less information publicly available about foreign companies than about a U.S. company, and many foreign companies are not subject to accounting, auditing, and financial reporting standards, regulatory framework and practices comparable to those in the U.S.
Olstein All Cap Value Fund | ADR Risk Member  
Prospectus [Line Items] rr_ProspectusLineItems  
Risk [Text Block] rr_RiskTextBlock
ADR Risk. ADRs are generally subject to the same risks as foreign securities because their values depend on the performance of the underlying foreign securities. Holders of unsponsored ADRs generally bear all the costs of such depositary receipts, and the issuers of unsponsored ADRs frequently are under no obligation to distribute shareholder communications received from the company that issues the underlying foreign securities or to pass through voting rights to the holders of the ADRs.

Strategy Narrative [Text Block] rr_StrategyNarrativeTextBlock
The Fund seeks to achieve its objectives by investing primarily in a diversified portfolio of common stocks of small- and mid-sized companies (“small-cap” or “mid-cap” stocks) that OCM believes are selling at a significant discount to private market value. The Fund uses several valuation methods to determine private market value, all of which emphasize expected future free cash flow. Future free cash flow represents the cash that a company is able to generate from operations after any required investment to maintain or expand its asset base (i.e., after required capital expenditures and working capital needs). For purposes of this investment policy, the Fund considers “small- and mid-sized companies” to be those with market capitalization values (share price multiplied by the number of shares of common stock outstanding) within the range represented in the Russell 2500TM Index (as of September 30, 2024, the Index’s weighted average market capitalization was approximately $7.66 billion and the largest company in the Index had a market capitalization of approximately $36.47 billion).
OCM follows an accounting-driven, value-oriented approach that emphasizes looking behind the numbers of financial statements based on the belief that the price of a common stock may not reflect the intrinsic value of the issuing company’s underlying business.
When evaluating the value of stocks for the Fund, OCM undertakes an in-depth analysis of financial statements, as it seeks to identify early signs of potential changes in a company’s ability to generate sustainable free cash flow as well as its potential to grow that may not be recognized by the financial markets. When determining sustainable free cash flow and the quality of earnings, OCM assesses the accounting practices and assumptions used to construct financial statements against the economic reality of the company’s business. OCM believes that in-depth analysis of financial statements reveals the success of a company’s strategy, the sustainability of its performance and the impact of
management decisions on future cash flow. OCM further believes that such an analysis is more useful to an investor than management forecasts or earnings guidance.
OCM believes that the management of small- to mid-sized companies face unique strategic choices, challenges, and problems, often as a result of the company’s size or expectations for growth. OCM believes stock prices often fall below a company’s private market value as a result of a short-term focus on, or an overreaction to, negative information regarding the company or its expected growth, negative information regarding its industry, or negative overall market psychology. The Fund seeks to capitalize on market volatility and the valuation extremes specific to a company by purchasing its stock at a discount to OCM’s estimate of private market value, which could result in above-average capital appreciation if such discount is corrected by market forces or other catalysts that change negative perceptions of the company.
The Fund’s bottom-up analysis seeks to identify companies with unique business fundamentals and a competitive edge, which usually provide a greater predictability of future free cash flow. Companies with free cash flow have the potential to enhance shareholder value by increasing dividends, repurchasing shares, reducing debt, engaging in strategic acquisitions, withstanding an economic downturn without adopting harmful short term strategies or being an attractive acquisition target.
The Fund may invest up to 20% of its net assets in foreign securities that are traded in U.S. dollars, including American Depositary Receipts ("ADRs") and will limit the Fund’s foreign investments to investments in developed countries, rather than countries with developing or emerging markets.

Performance Narrative [Text Block] rr_PerformanceNarrativeTextBlock
The bar chart and the performance table below provide some indication of the risks of investing in the Fund by showing changes in the performance of Class C shares of the Fund from year to year and by showing how the average annual returns of Class C shares, Class A shares and Adviser Class shares of the Fund over time compare to the performance of the Russell 2500TM Value Index and Russell 3000® Index. The Russell 2500TM Value Index and the Russell 3000® Index represent broad measures of market performance.  Fund returns shown in the bar chart do not reflect the 1.00% contingent deferred sales charge on Class C shares. Fund returns shown in the performance table reflect the maximum sales charge of 5.50% for the Fund’s Class A and the contingent deferred sales charge of 1.00% during the one year period for the Class C. The Fund’s past performance (before and after taxes) is not necessarily an indication of how the Fund will perform in the future. Updated performance information is available on the Fund’s website at https://www.olsteinfunds.com or by calling (800) 799‑2113.

Olstein Strategic Opportunities Fund | Risk Lose Money [Member]  
Prospectus [Line Items] rr_ProspectusLineItems  
Risk [Text Block] rr_RiskTextBlock As with any mutual fund, there are risks to investing.
Olstein Strategic Opportunities Fund | Risk Not Insured Depository Institution [Member]  
Prospectus [Line Items] rr_ProspectusLineItems  
Risk [Text Block] rr_RiskTextBlock An investment in the Fund is not a deposit of a bank and is not insured or guaranteed by the Federal Deposit Insurance Corporation ("FDIC") or any other governmental agency.
Olstein Strategic Opportunities Fund | General Market Risk Member  
Prospectus [Line Items] rr_ProspectusLineItems  
Risk [Text Block] rr_RiskTextBlock General Market Risk. The Fund’s net asset value ("NAV") and investment return will fluctuate based upon changes in the value of its portfolio securities. Certain securities selected for the Fund’s portfolio may be worth less than the price originally paid for them, or less than they were worth at an earlier time.
Olstein Strategic Opportunities Fund | Management Risk Member  
Prospectus [Line Items] rr_ProspectusLineItems  
Risk [Text Block] rr_RiskTextBlock Management Risk. The Fund is actively managed and may not meet its investment objective or may underperform the market or other mutual funds with similar strategies if OCM cannot successfully implement the Fund’s investment strategies.
Olstein Strategic Opportunities Fund | Equity Securities Risk Member  
Prospectus [Line Items] rr_ProspectusLineItems  
Risk [Text Block] rr_RiskTextBlock
Equity Securities 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 industries, sectors, geographic markets or companies in which the Fund invests.
Olstein Strategic Opportunities Fund | Small- And Mid-Sized Company Risk Member  
Prospectus [Line Items] rr_ProspectusLineItems  
Risk [Text Block] rr_RiskTextBlock
Small- and Mid-Sized Company Risk. Small- and mid-sized companies may be more vulnerable to adverse business or economic events than larger, more established companies. In particular, these companies may have an unproven or narrow technological base and limited product lines, distribution channels, and market and financial resources, and small capitalization companies also may be dependent on entrepreneurial management, making the companies more susceptible to certain setbacks and reversals.
Olstein Strategic Opportunities Fund | Value-Style Investing Risk Member  
Prospectus [Line Items] rr_ProspectusLineItems  
Risk [Text Block] rr_RiskTextBlock
Value-Style Investing Risk. The Fund uses a value-oriented investment approach. However, a particular value stock may not increase in price as anticipated by OCM (and may actually decline in price) if other investors fail to recognize the stock’s value or if a catalyst that OCM believes will increase the price of the stock does not occur or does not affect the price of the stock in the manner or to the degree anticipated.
Olstein Strategic Opportunities Fund | Liquidity Risk Member  
Prospectus [Line Items] rr_ProspectusLineItems  
Risk [Text Block] rr_RiskTextBlock
Liquidity Risk. Liquidity risk is the risk that certain securities may be difficult or impossible to sell at the time and price that the Fund would like to sell the security, which can have a negative impact on Fund performance. The Fund may invest in small- and mid-sized companies, which may have a smaller “float” (the number of shares that are available to trade) and attract less market interest, and, therefore, may be subject to liquidity risk.
Olstein Strategic Opportunities Fund | Foreign Investing Risk Member  
Prospectus [Line Items] rr_ProspectusLineItems  
Risk [Text Block] rr_RiskTextBlock
Foreign Investing Risk. Investing in foreign companies typically involves more risks than investing in U.S. companies. These risks can increase the potential for losses in the Fund and may include risks related to currency exchange rate fluctuations, country or government specific issues (for example, terrorism, war, social and economic instability, currency devaluations, and restrictions on foreign investment or the movement of assets), unfavorable trading practices, less government supervision, less publicly available information, limited trading markets and greater volatility. There may be less information publicly available about foreign companies than about a U.S. company, and many foreign companies are not subject to accounting, auditing, and financial reporting standards, regulatory framework and practices comparable to those in the U.S.
Olstein Strategic Opportunities Fund | ADR Risk Member  
Prospectus [Line Items] rr_ProspectusLineItems  
Risk [Text Block] rr_RiskTextBlock
ADR Risk. ADRs are generally subject to the same risks as foreign securities because their values depend on the performance of the underlying foreign securities. Holders of unsponsored ADRs generally bear all the costs of such depositary receipts, and the issuers of unsponsored ADRs frequently are under no obligation to distribute shareholder communications received from the company that issues the underlying foreign securities or to pass through voting rights to the holders of the ADRs.
Olstein Strategic Opportunities Fund | Epidemic Risk Member  
Prospectus [Line Items] rr_ProspectusLineItems  
Risk [Text Block] rr_RiskTextBlock
Epidemic Risk. Widespread disease, including pandemics and epidemics have been and can be highly disruptive to economies and markets, adversely impacting individual companies, sectors, industries, markets, currencies, interest and inflation rates, credit ratings, investor sentiment, and other factors affecting the value of the Fund’s investments. Given the increasing interdependence among global economies and markets, conditions in one country, market, or region are increasingly likely to adversely affect markets, issuers, and/or foreign exchange rates in other countries, including the U.S. These disruptions could prevent the Fund from executing advantageous investment decisions in a timely manner and negatively impact the Fund’s ability to achieve its investment objectives. Any such event(s) could have a significant adverse impact on the value and risk profile of the Fund.

[1] Purchases of $1 million or more, or purchases into account(s) with accumulated value of $1 million or more that were not subject to a front-end sales charge, are subject to a contingent deferred sales charge (“CDSC”) of 1.00% if sold within one year of the purchase date.
[2] The total return figures for Class A include the maximum front-end sales charge of 5.50% imposed on purchases.
[3] The Fund is the accounting successor to the Olstein All Cap Value Fund, a series of The Olstein Funds (the “Predecessor All Cap Value Fund”). Accordingly, the performance shown in the bar chart and performance table for periods prior to September 14, 2018, represents the performance of the Predecessor All Cap Value Fund.
[4] The 1 Year total return figures for Class C assume that the shareholder redeemed at the end of the first year and paid the CDSC of 1.00%. The average annual total returns for Class C shown for 5 Years and 10 Years do not include the CDSC because there is no CDSC if shares are held longer than 1 year.
[5] OCM has contractually agreed to waive its management fees and/or pay Fund expenses, in order to ensure that Total Annual Fund Operating Expenses of each class of shares (excluding any front-end or contingent deferred loads, taxes, leverage/borrowing interest, interest expense, dividends paid on short sales, brokerage commissions and other transactional expenses, Acquired Fund Fees and Expenses, extraordinary expenses, 12b-1 fees, and shareholder servicing fees) do not exceed 1.35% of the average daily net assets of the Fund. Fees waived and expenses paid by OCM under this Operating Expenses Limitation Agreement may be recouped by OCM for a period of thirty-six months following the month during which such fee waiver or expense payment was made, if such recoupment can be achieved without exceeding the expense limit in effect at the time the fee waiver and expense payment occurred, or at the time of recoupment. The Operating Expenses Limitation Agreement is indefinite in term and cannot be terminated through at least October 28, 2025. Thereafter, the agreement may be terminated at any time upon 60 days’ written notice by the Trust’s Board of Trustees or OCM, with the consent of the Board.
[6] Purchases of $1 million or more, or purchases into account(s) with accumulated value of $1 million or more that were not subject to a front-end sales charge, are subject to a contingent deferred sales charge (“CDSC”) of 1.00% if sold within one year of the purchase date.
