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 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 19.47% of the average value of its portfolio.

Strategy [Heading] rr_StrategyHeading Principal Investment Strategies of the Fund
Strategy Narrative [Text Block] rr_StrategyNarrativeTextBlock
Under normal circumstances, the Fund invests at least 80% of its assets in the securities of large capitalization companies. The Fund considers “large capitalization companies” to be companies, at the time of purchase, whose market capitalizations are within the range of the market capitalizations in the Russell 1000® Index.
The Fund also may invest in derivatives such as futures, forwards and other similar instruments in order to “equitize” cash balances by gaining exposure to relevant equity markets. To the extent that derivatives have economic characteristics similar to the securities of large capitalization companies, they will be counted as such for purposes of the Fund’s 80% investment policy.
The sub-advisor uses a rules-based methodology that emphasizes quantitatively-based stock selection, portfolio construction and efficient implementation. The Fund seeks to capture common sources of active equity returns, including the following factors: value (i.e., how attractively a stock is priced relative to its “fundamentals,” such as book value and free cash flow), momentum (i.e., whether a company’s share price is trending up or down) and quality (i.e., profitability). The sub-advisor seeks to capitalize on the low correlations in returns across these factors by diversifying exposure to securities selected based on such factors. The sub-advisor may, in its discretion, make changes to its quantitative techniques, or use other quantitative techniques that are based on the sub-advisor’s proprietary research.
The sub-advisor constructs the Fund’s portfolio by investing in the securities comprising the Russell 1000® Index and adjusting the relative weight of each security based on the security’s attractiveness when evaluated based on the factors as described above, subject to the Fund being constrained to long-only positions. Based on the sub-advisor’s judgment, the Fund expects that its portfolio will be overweight with respect to certain securities (i.e., the Fund will hold a greater percentage of those securities than the index) and underweight with respect to others (i.e., the Fund will hold a lesser percentage of those securities than the index), and that such weightings may change over time. The
percentage of the Fund’s portfolio exposed to any single security will vary from time to time as the weightings of the securities within the Fund change. The degree to which components of the Fund represent certain sectors or industries may change over time.
The Fund lends its portfolio securities to seek to generate additional income.

Risk [Text Block] rr_RiskTextBlock Derivatives Risk: A derivative is an instrument with a value based on the performance of an underlying currency, security, index or other reference asset. The use of derivatives involves risks different from, or greater than, the risks associated with investing in more traditional investments. Derivatives involve costs, may create leverage and may be illiquid, volatile, and difficult to value. The Fund may not be able to close out or sell a derivative position at a particular time or at an anticipated price. The use of derivatives could also result in a loss if the counterparty to the transaction does not perform as promised, including because of such counterparty’s bankruptcy or insolvency. The investment results achieved by the use of derivatives by the Fund may not match or fully offset changes in the value of the underlying currency, security, index or other reference asset that it was attempting to hedge or the investment opportunity the Fund was attempting to pursue.

The Fund could also lose money in connection with securities lending transactions if it does not recover the loaned securities and/or the value of the collateral falls, including the value of investments made with cash collateral. Securities lending also may have certain adverse tax consequences. The Fund is not obligated to engage in securities lending, and may discontinue its securities lending activities at any time.

Strategy [Heading] rr_StrategyHeading Principal Investment Strategies of the Fund
Strategy Narrative [Text Block] rr_StrategyNarrativeTextBlock
Under normal circumstances, the Fund invests at least 80% of its assets in securities and other instruments that provide exposure to emerging market countries. For purposes of this policy, securities and other instruments that provide exposure to emerging market countries include: (i) securities issued by entities which are located, incorporated or have significant business activities in or are impacted by economic developments in developing or emerging market countries, (ii) securities denominated in, or linked to, currencies or interest rates of an emerging market country or countries, and (iii) derivatives or pooled structures (such as exchange-traded funds (“ETFs”)) that are linked to
emerging markets. The Fund considers emerging market countries to be those defined by the MSCI Emerging Markets Index. The Fund will, under normal circumstances, seek exposure to a minimum of three emerging market countries.
The Fund mainly invests in equity securities of issuers in emerging market countries. The Fund’s investments in equity securities may include common stocks, unit stocks, stapled securities, ETFs and preferred stocks of companies of any size capitalization. The Fund also may invest in depositary receipts, including American Depositary Receipts (“ADRs”) of foreign companies and Global Depositary Receipts (“GDRs”). Depositary receipts are typically issued by a U.S. or foreign bank or trust company and evidence ownership of underlying securities issued by a foreign corporation.
The Fund also may invest in derivatives such as futures, forwards and other similar instruments in order to (i) “equitize” cash balances by gaining exposure to relevant equity markets; and (ii) hedge exposure to foreign currencies. The Fund may engage in currency futures and currency forwards for the purpose of hedging exposures within the Fund to non-dollar-denominated assets. In general, the use of currency derivatives for hedging may reduce the overall risk level of the Fund, albeit at a cost that may lower overall performance.
The sub-advisor uses a rules-based methodology that emphasizes quantitatively-based stock selection, portfolio construction and efficient implementation. The Fund seeks to capture common sources of active equity returns, including the following factors: value (i.e., how attractively a stock is priced relative to its “fundamentals,” such as book value and free cash flow), momentum (i.e., whether a company’s share price is trending up or down) and quality (i.e., profitability). The sub-advisor seeks to capitalize on the low correlations in returns across these factors by diversifying exposure to securities selected based on such factors. The sub-advisor may, in its discretion, make changes to its quantitative techniques, or use other quantitative techniques that are based on the sub-advisor’s proprietary research.
The sub-advisor constructs the Fund’s portfolio by investing in the securities comprising the MSCI Emerging Markets Index and adjusting the relative weight of each security based on the security’s attractiveness when evaluated based on the factors as described above, subject to the Fund being constrained to long-only positions. Based on the sub-advisor’s judgment, the Fund expects that its portfolio will be overweight with respect to certain securities (i.e., the Fund will hold a greater percentage of those securities than the index) and underweight with respect to others (i.e., the Fund will hold a lesser percentage of those securities than the index), and that such weightings may change over time.

The degree to which components of the Fund represent certain sectors or industries may change over time.

Risk [Text Block] rr_RiskTextBlock Regional Risk. To the extent that the Fund invests a significant portion of its assets in a specific geographic region, the Fund will have increased exposure to the risks affecting that specific geographic region. In the event of economic or political turmoil or a deterioration of diplomatic relations in a region where a substantial portion of the Fund’s assets are invested, the Fund may experience substantial illiquidity or reduction in the value of the Fund’s investments. In addition, adverse economic events in a certain region can impact securities of issuers in other countries whose economies appear to be unrelated. There are special risks associated with investments in China, Hong Kong and Taiwan, including exposure to currency fluctuations, less liquidity, expropriation, confiscatory taxation, nationalization and exchange control regulations (including currency blockage). Inflation and rapid fluctuations in inflation and interest rates have had, and may continue to have, negative effects on the economy and securities markets of China, Hong Kong and Taiwan. The Chinese economy is heavily dependent on its large export sector and its economic growth may be adversely affected by trade disputes with key trading partners and escalating tariffs imposed on goods and services it produces. Investments in Chinese companies may be made through a special structure known as a variable interest entity (“VIE”). VIEs are common and are are well known to Chinese officials and regulators, but historically the VIE structure has not been formally recognized under Chinese law. There is uncertainty as to whether Chinese courts or arbitration bodies would enforce the contractual rights of foreign investors in a VIE structure and whether Chinese officials and regulators will reverse their acceptance of the VIE structure generally, or with respect to certain industries.

Risk [Text Block] rr_RiskTextBlock Small and Medium Capitalization Company Risk: Small and medium capitalization companies often have narrower markets, fewer products or services to offer and more limited managerial and financial resources than do larger, more established companies. As a result, their performance can be more volatile, and they face a greater risk of business failure, which could increase the volatility and risk of loss of the Fund's assets.

Prospectus [Line Items] rr_ProspectusLineItems  
Risk [Text Block] rr_RiskTextBlock Derivatives Risk: A derivative is an instrument with a value based on the performance of an underlying currency, security, index or other reference asset. The use of derivatives involves risks different from, or greater than, the risks associated with investing in more traditional investments. Derivatives involve costs, may create leverage and may be illiquid, volatile, and difficult to value. The Fund may not be able to close out or sell a derivative position at a particular time or at an anticipated price. The use of derivatives could also result in a loss if the counterparty to the transaction does not perform as promised, including because of such counterparty’s bankruptcy or insolvency. The investment results achieved by the use of derivatives by the Fund may not match or fully offset changes in the value of the underlying currency, security, index or other reference asset that it was attempting to hedge or the investment opportunity the Fund was attempting to pursue. For example, with currency derivatives, there may be an imperfect correlation between a Fund’s portfolio holdings of securities denominated in a particular currency and the currencies underlying the currency derivatives entered into by the Fund.

The risks of owning an ETF generally reflect the risks of owning the underlying securities held by the ETF, although a lack of liquidity in an ETF could result in it being more volatile. In addition, ETF shares may trade at a premium or discount relative to their net asset value. ETFs have management fees and other expenses which the Fund will indirectly bear.

The Fund could also lose money in connection with securities lending transactions if it does not recover the loaned securities and/or the value of the collateral falls, including the value of investments made with cash collateral. Securities lending also may have certain adverse tax consequences. The Fund is not obligated to engage in securities lending, and may discontinue its securities lending activities at any time.

Strategy [Heading] rr_StrategyHeading Principal Investment Strategies of the Fund
Strategy Narrative [Text Block] rr_StrategyNarrativeTextBlock
Under normal circumstances, the Fund invests at least 80% of its assets in the securities of small-to-medium capitalization companies. The Fund considers “small-to-medium capitalization companies” to be companies, at the time of purchase, whose market capitalizations are within the range of the market capitalizations in the Russell 2500TM Index.
The Fund may invest in derivatives such as futures, forwards and other similar instruments in order to “equitize” cash balances by gaining exposure to relevant equity markets. To the extent that derivatives have economic characteristics similar to the securities of small-to-medium capitalization companies, they will be counted as such for purposes of the Fund’s 80% investment policy.
The sub-advisor uses a rules-based methodology that emphasizes quantitatively-based stock selection, portfolio construction and efficient implementation. The Fund seeks to capture common sources of active equity returns, including the following factors: value (i.e., how attractively a stock is priced relative to its “fundamentals,” such as book value and free cash flow), momentum (i.e., whether a company’s share price is trending up or down) and quality (i.e., profitability). The sub-advisor seeks to capitalize on the low correlations in returns across these factors by diversifying exposure to securities selected based on such factors. The sub-advisor may, in its discretion, make changes to its quantitative techniques, or use other quantitative techniques that are based on the sub-advisor’s proprietary research.
The sub-advisor constructs the Fund’s portfolio by investing in the securities comprising the Russell 2500TM Index and adjusting the relative weight of each security based on the security’s attractiveness when evaluated based on the factors as described above, subject to the Fund being constrained to long-only positions. Based on the sub-advisor’s judgment, the Fund expects that its portfolio will be overweight with respect to certain securities (i.e., the Fund will hold a greater percentage of those securities than the index) and underweight with respect to others (i.e., the Fund will hold a lesser percentage of those securities than the index), and that such weightings may change over time. The percentage of the Fund’s portfolio exposed to any single security will vary from time to time as the weightings of the securities within the Fund change. The degree to which components of the Fund represent certain sectors or industries may change over time.
The Fund lends its portfolio securities to seek to generate additional income.

Strategy [Heading] rr_StrategyHeading Principal Investment Strategies of the Fund
Strategy Narrative [Text Block] rr_StrategyNarrativeTextBlock
Under normal circumstances, the Fund invests at least 80% of its assets in equity securities. The Fund invests primarily in equity securities incorporated or traded outside the United States. Generally, the Fund’s assets will be invested in securities of companies located in developed countries. The Fund considers developed countries to be those defined by the MSCI World ex-USA Index. The Fund will, under normal circumstances, invest in a minimum of three countries outside of the United States.
The Fund’s investments in equity securities may include common stocks, unit stocks, stapled securities, exchange-traded funds (“ETFs”) and preferred stocks of companies of any size capitalization. The Fund also may invest in depositary receipts, including American Depositary Receipts (“ADRs”) of foreign companies and Global Depositary Receipts (“GDRs”). Depositary receipts are typically issued by a U.S. or foreign bank or trust company and evidence ownership of underlying securities issued by a foreign corporation.
The Fund also may invest in derivatives such as futures, forwards and other similar instruments in order to (i) “equitize” cash balances by gaining exposure to relevant equity markets; and (ii) hedge exposure to foreign currencies. The Fund may engage in currency futures and currency forwards for the purpose of hedging exposures within the Fund to non-dollar-denominated assets. In general, the use of currency derivatives for hedging may reduce the overall risk level of the Fund, albeit at a cost that may lower overall performance. To the extent that derivatives have economic characteristics similar to equity securities, they will be counted as such for purposes of the Fund’s 80% investment policy.

The Fund seeks to capture common sources of active equity returns, including the following factors: value (i.e., how attractively a stock is priced relative to its “fundamentals,” such as book value and free cash flow), momentum (i.e., whether a company’s share price is trending up or down) and quality (i.e., profitability). The sub-advisor seeks to capitalize on the low correlations in returns across these factors by diversifying exposure to securities selected based on such factors. The sub-advisor may, in its discretion, make changes to its quantitative techniques, or use other quantitative techniques that are based on the sub-advisor’s proprietary research.
The sub-advisor constructs the Fund’s portfolio by investing in the securities comprising the MSCI World ex-USA Index and adjusting the relative weight of each security based on the security’s attractiveness when evaluated based on the factors as described above, subject to the Fund being constrained to long-only positions. Based on the sub-advisor’s judgment, the Fund expects that its portfolio will be overweight with respect to certain securities (i.e., the Fund will hold a greater percentage of those securities than the index) and underweight with respect to others (i.e., the Fund will hold a lesser percentage of those securities than the index), and that such weightings may change over time. The percentage of the Fund’s portfolio exposed to any single security will vary from time to time as the weightings of the securities within the Fund change. The degree to which components of the Fund represent certain sectors or industries may change over time.
The Fund lends its portfolio securities to seek to generate additional income.

Risk [Text Block] rr_RiskTextBlock Derivatives Risk: A derivative is an instrument with a value based on the performance of an underlying currency, security, index or other reference asset. The use of derivatives involves risks different from, or greater than, the risks associated with investing in more traditional investments. Derivatives involve costs, may create leverage, and may be illiquid, volatile, and difficult to value. The Fund may not be able to close out or sell a derivative position at a particular time or at an anticipated price. In addition, the use of currency derivatives may not match or fully offset changes in the value of the underlying non-dollar-denominated or bank assets. The use of derivatives could also result in a loss if the counterparty to the transaction does not perform as promised, including because of such counterparty’s bankruptcy or insolvency. The investment results achieved by the use of derivatives by the Fund may not match or fully offset changes in the value of the underlying currency, security, index or other reference asset that it was attempting to hedge or the investment opportunity the Fund was attempting to pursue. For example, with currency derivatives, there may be an imperfect correlation between a Fund’s portfolio holdings of securities denominated in a particular currency and the currencies underlying the currency derivatives entered into by the Fund.

Strategy [Heading] rr_StrategyHeading Principal Investment Strategies of the Fund
Strategy Narrative [Text Block] rr_StrategyNarrativeTextBlock
Under normal circumstances, the Fund will invest at least 80% of its assets in fixed income securities.
The Fund will primarily invest in fixed income securities that are rated investment grade or better (i.e., rated in one of the four highest rating categories by a Nationally Recognized Statistical Rating Organization (“NRSRO”) or determined to be of comparable quality by the Fund’s sub-advisor if the security is unrated). The fixed income securities in which the Fund invests may have maturities of any length.
The Fund is designed to allow the sub-advisor to invest in the core sectors of the U.S. domestic fixed income market (as defined by the Fund’s benchmark index) while seeking to maintain the Fund’s duration within a relatively close range to the duration of the Fund’s benchmark index. Duration is a measure of the sensitivity of the price of a debt security (or a portfolio of debt securities) to changes in
interest rates. The prices of debt securities with shorter durations generally will be less affected by changes in interest rates than the prices of debt securities with longer durations.
The sub-advisor combines top-down views with bottom-up driven research to manage the Fund’s assets. Top-down views set by the portfolio management team determine risk targets, sector allocation, duration and yield curve positioning. Sector teams are responsible for credit research and building bottom-up driven sector portfolios that meet the targets set by the portfolio management team.
While the Fund will primarily invest in fixed income securities that are rated investment grade, the Fund may, at times, hold debt securities that are rated below investment grade as a result of downgrades in the rating of the securities subsequent to their purchase by the Fund.
The Fund may buy and sell certain types of exchange-traded and over-the-counter derivative instruments for duration and risk management purposes and otherwise in pursuit of the Fund’s investment objective. The types of derivatives in which the Fund may invest include, but are not limited to, futures contracts, swaps agreements and options.
The Fund lends its portfolio securities to seek to generate additional income.

Service Shares Prospectus | GuideMark(R) Core Fixed Income Fund | Debt/Fixed Income Securities Risk Member  
Prospectus [Line Items] rr_ProspectusLineItems  
Risk [Text Block] rr_RiskTextBlock Debt/Fixed Income Securities Risk: An increase in interest rates typically causes a fall in the value of the debt securities in which the Fund may invest. Conversely, very low or negative interest rates may heighten the Fund's susceptibility to interest rate risk and diminish yield and performance.The value of your investment in the Fund may change in response to changes in the credit ratings of the debt securities in the Fund's portfolio. Moreover, rising interest rates or lack of market participants may lead to decreased liquidity in the bond and loan markets, making it more difficult for the Fund to sell its holdings at a time when the Fund's manager might wish to sell. Lower rated securities ("junk bonds") are generally subject to greater risk of loss of your money than higher rated securities. Issuers may (increase) decrease prepayments of principal when interest rates (fall) increase, affecting the maturity of the debt security and causing the value of the security to decline. To the extent the Fund or an Underlying Fund invests in derivatives tied to fixed income markets, the Fund or Underlying Fund may be more substantially exposed to these risks than a fund that does not invest in derivatives.

Risk [Text Block] rr_RiskTextBlock Tax Risk Inflation-Indexed Securities: Any increase in the principal amount of an inflation-indexed security may be included for tax purposes in the Fund’s gross income, even though no cash attributable to such gross income has been received by the Fund. In such event, the Fund may be required to make annual distributions to shareholders that exceed the cash it has otherwise received. In order to pay such distributions, the Fund may be required to raise cash by selling portfolio investments. The sale of such investments could result in capital gains to the Fund and additional capital gain distributions to shareholders. In addition, adjustments during the taxable year for deflation to an inflation-indexed bond held by the Fund may cause amounts previously distributed to shareholders in the taxable year as income to be characterized as a return of capital.

Risk [Text Block] rr_RiskTextBlock U.S. Government Agency Obligations Risk: Government agency obligations have different levels of credit support and, therefore, different degrees of credit risk. Some securities issued by agencies and instrumentalities of the U.S. Government are supported by the full faith and credit of the United States, but others are neither insured nor guaranteed by the U.S. Government. For example, Connecticut Avenue Securities issued by the Federal National Mortgage Association and Structured Agency Credit Risk debt notes issued by the Federal Home
Loan Mortgage Association carry no guarantee whatsoever and the risk of default associated with these securities would be borne by the Fund. The U.S. Department of the Treasury has the authority to provide financial support to these debt obligations, but no assurance can be given that the U.S. Government will do so.

Interest payments on inflation-indexed securities will fluctuate as the principal and/or interest is adjusted for inflation and can be unpredictable.

Risk [Text Block] rr_RiskTextBlock Portfolio Turnover Risk: Depending on market and other conditions, the Fund may experience a high portfolio turnover, which may result in higher brokerage costs and transaction costs (which could reduce investment returns). Distributions of net short-term capital gains are taxable as ordinary income when Fund shares are held in a taxable account. A fund with a high portfolio turnover rate (a measure of how frequently assets within a fund are bought and sold) is more likely to generate short-term capital gains than a fund with a low portfolio turnover rate.

Prospectus [Line Items] rr_ProspectusLineItems  
Risk [Text Block] rr_RiskTextBlock Variable Rate Securities Risk: Changes in interest rates on variable rate securities may lag behind changes in market rates, causing the value of such securities to decline during periods of rising interest rates until their interest rates reset to market rates. During periods of declining interest rates, interest rates on variable rate securities generally reset downward, and their market value is unlikely to rise to the same extent as the value of comparable fixed rate securities. Newly originated variable rate securities (including reissuances and restructured loans) may possess lower levels of credit document protections than has historically been the case. Accordingly, in the event of default the Fund may experience lower levels of recoveries than has historically been the norm.

Risk [Text Block] rr_RiskTextBlock Extension Risk: As interest rates rise, repayments of principal on certain debt securities, including, but not limited to, floating rate loans and mortgage-related securities, may occur at a slower rate than expected and the expected maturity of those securities could lengthen as a result. Securities that are subject to extension risk generally have a greater potential for loss when prevailing interest rates rise, which could cause their values to fall sharply. Interest-only and principal-only securities are especially sensitive to interest rate changes, which can affect not only their prices but can also change the income flows and repayment assumptions about those investments.

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 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 18.58% of the average value of its portfolio.

Strategy [Heading] rr_StrategyHeading Principal Investment Strategies of the Fund
Strategy Narrative [Text Block] rr_StrategyNarrativeTextBlock
The Fund operates as a fund of funds, investing primarily in registered mutual funds, including exchange-traded funds (“ETFs”). The funds in which the Fund may invest are referred to herein as the “Underlying Funds.” The Advisor believes that investing in Underlying Funds provides the Fund with an efficient means of creating a portfolio that provides investors with indirect exposure to a broad range of securities. By investing in the Fund, you will indirectly bear fees and expenses of the Underlying Funds in addition to the Fund’s direct fees and expenses. In order to obtain exposure to certain markets, asset classes or active management styles, the Fund may buy Underlying Funds managed by the Advisor or its affiliates, which, in turn, invest in various securities, including ETFs. The Fund may also invest directly in securities and other exchange-traded products, such as exchange-traded notes (“ETNs”).
In seeking to maximize total return, under normal circumstances, the Fund’s assets are allocated, either directly or indirectly via the Underlying Funds, among various asset classes, including domestic and international equity securities (including American Depositary Receipts (“ADRs”) and Global Depositary Receipts (“GDRs”)) and domestic and international fixed income securities. The intention is to capture broad capital market returns, while seeking to balance the pursuit of maximum total return against the control of risk in the portfolio.
In addition to the general allocation into equity, fixed income and cash equivalent asset classes, the Fund’s assets are also typically allocated among a variety of sub-asset classes. The Fund’s equity investments typically include, either directly or indirectly via the Underlying Funds, a mix of weightings of larger and smaller capitalization equity securities, growth and value stocks, and equity securities from developed and emerging international markets. The Fund’s fixed income investments may be expected to be allocated, either directly or indirectly via the Underlying Funds, among corporate bonds, mortgage-backed or asset-backed securities, securities issued by the U.S. and foreign
governments or their agencies and instrumentalities, and to higher-yielding bonds (sometimes referred to as “junk bonds”), including emerging market debt. Typically, a significant portion of the Fund’s fixed income allocation will be in non-investment grade fixed income investments with varying maturities.
The Advisor’s asset allocation decisions are based on different factors and analytical approaches, derived from asset allocation approaches developed by various research providers and considered by the Advisor in constructing the Fund’s portfolio.
The Fund’s asset allocation mix among equity, fixed income and cash equivalent money market securities is intended to generally remain consistent for longer periods of time. Under normal circumstances, the Fund is expected to allocate between 65% and 100% of its assets to equity securities or investments that provide exposure to equity securities. Over time, the asset allocation mix may change as a result of changing capital market assumptions. Under normal market conditions, the Fund is expected to allocate approximately 99% of its assets to equity securities or investments that provide exposure to equity securities and 1% of its assets to fixed income securities or investments that provide exposure to fixed income securities, including cash equivalents. The Fund also may allocate significant assets to international equity markets: up to 45% to developed international markets and up to 35% to emerging markets.
The Fund may invest in Underlying Funds that use derivatives for risk management purposes or as part of their investment strategies. An Underlying Fund may use derivatives to enhance returns, to manage or adjust the risk profile of the Underlying Fund, to replace more traditional direct investments, or to obtain exposure to certain markets.
The Fund lends its portfolio securities to seek to generate additional income.

Service Shares Prospectus | GuidePath(R) Growth Allocation Fund | Derivatives Risk Member  
Prospectus [Line Items] rr_ProspectusLineItems  
Risk [Text Block] rr_RiskTextBlock Derivatives Risk: A derivative is an instrument with a value based on the performance of an underlying currency, security, index or other reference asset. The use of derivatives involves risks different from, or greater than, the risks associated with investing in more traditional investments. Derivatives involve costs, may create leverage, and may be illiquid, volatile, and difficult to value. The Fund may not be able to close out or sell a derivative position at a particular time or at an anticipated price. The use of derivatives could also result in a loss if the counterparty to the transaction does not perform as promised, including because of such counterparty’s bankruptcy or insolvency. The investment results achieved by the use of derivatives by the Fund may not match or fully offset changes in the value of the underlying currency, security, index or other reference asset that it was attempting to hedge or the investment opportunity the Fund was attempting to pursue.
Service Shares Prospectus | GuidePath(R) Growth Allocation Fund | Debt/Fixed Income Securities Risk Member  
Prospectus [Line Items] rr_ProspectusLineItems  
Risk [Text Block] rr_RiskTextBlock Debt/Fixed Income Securities Risk: An increase in interest rates typically causes a fall in the value of the debt securities in which the Fund may invest. Conversely, very low or negative interest rates may heighten the Fund's susceptibility to interest rate risk and diminish yield and performance.The value of your investment in the Fund may change in response to changes in the credit ratings of the debt securities in the Fund's portfolio. Moreover, rising interest rates or lack of market participants may lead to decreased liquidity in the bond and loan markets, making it more difficult for the Fund to sell its holdings at a time when the Fund's manager might wish to sell. Lower rated securities ("junk bonds") are generally subject to greater risk of loss of your money than higher rated securities. Issuers may (increase) decrease prepayments of principal when interest rates (fall) increase, affecting the maturity of the debt security and causing the value of the security to decline. To the extent the Fund or an Underlying Fund invests in derivatives tied to fixed income markets, the Fund or Underlying Fund may be more substantially exposed to these risks than a fund that does not invest in derivatives.

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. The Fund does not pay transaction costs when buying and selling shares of other mutual funds, however, the underlying funds pay transaction costs when buying and selling securities for their portfolio. 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 19.92% of the average value of its portfolio.

Strategy [Heading] rr_StrategyHeading Principal Investment Strategies of the Fund
Strategy Narrative [Text Block] rr_StrategyNarrativeTextBlock
The Fund operates as a fund of funds, investing primarily in registered mutual funds, including exchange-traded funds (“ETFs”). The funds in which the Fund may invest are referred to herein as the “Underlying Funds.” The Advisor believes that investing in Underlying Funds provides the Fund with an efficient means of creating a portfolio that provides investors with indirect exposure to a broad range of securities. By investing in the Fund, you will indirectly bear fees and expenses of the Underlying Funds in addition to the Fund’s direct fees and expenses. In order to obtain exposure to certain markets, asset classes or active management styles, the Fund may buy Underlying Funds managed by the Advisor or its affiliates, which, in turn, invest in various securities, including ETFs. The Fund may also invest directly in securities and other exchange-traded products, such as exchange-traded notes (“ETNs”).
In seeking to maximize total return, under normal circumstances, the Fund’s assets are allocated, either directly or indirectly via the Underlying Funds, into a diversified portfolio consisting of domestic and international equity securities (including American Depositary Receipts (“ADRs”) and Global Depositary Receipts (“GDRs”)) and domestic and international fixed income securities. The intention is to capture broad capital market returns over the long term, while seeking to balance the pursuit of maximum total return against the control of risk in the portfolio.
In addition to the general strategic allocation into equity, fixed income and cash equivalent asset classes, the Fund’s assets are also typically allocated among a variety of sub-asset classes. The Fund’s equity investments typically include, either directly or indirectly via the Underlying Funds, a mix of weightings of larger and smaller capitalization equity securities, growth and value stocks, and equity securities
from developed and emerging international markets. The Fund’s fixed income investments may be expected to be allocated, either directly or indirectly via the Underlying Funds, among corporate bonds, mortgage-backed or asset-backed securities, securities issued by the U.S. and foreign governments or their agencies and instrumentalities, and to higher-yielding bonds (sometimes referred to as “junk bonds”), including emerging market debt. A significant portion of the Fund’s fixed income allocation may be in non-investment grade fixed income investments with varying maturities. The Fund may also allocate a portion of its assets to commodities related investments.
The Advisor’s asset allocation decisions will be based on different factors and analytical approaches, derived from asset allocation approaches developed by various research providers and considered by the Advisor in constructing the Fund’s portfolio.
Under normal circumstances, the Fund is expected to allocate between 15% and 55% of its assets to equity securities and investments that provide exposure to equity securities and between 45% and 85% of its assets to fixed income securities and investments that provide exposure to fixed income securities. Over time, the asset allocation mix may change as a result of changing capital market assumptions or short-term market opportunities. Under normal market conditions, the Fund is expected to allocate approximately 35% of its assets to equity securities and investments that provide exposure to equity securities and 65% of its assets to fixed income securities and investments that provide exposure to fixed income securities, including cash equivalents. For example, if the Advisor believes that the stock market is undervalued, it may increase the equity allocation, or if the Advisor believes that the stock market is overvalued, it may decrease the equity allocation. Within these ranges, the Advisor has the ability to overweight or underweight certain asset classes in pursuit of increased return or reduced risk in the short to intermediate term. The Fund’s portfolio will be rebalanced periodically as a result of asset class performance causing drift away from the targeted asset allocation mix.
The Fund may invest in Underlying Funds that use derivatives to earn income and enhance returns, to manage or adjust their risk profile, to replace more traditional direct investments, or to obtain exposure to certain markets.
The Fund lends its portfolio securities to seek to generate additional income.

Risk [Text Block] rr_RiskTextBlock Fund of Funds Risk: The Fund is subject to fund of funds risk, which means that the ability of the Fund to meet its investment objective is directly related to the ability of the Underlying Funds to meet their investment objectives.  There can be no assurance that either the Fund or the Underlying Funds will achieve their investment objectives. Additionally, each Fund may invest in other investment companies for which the Advisor or an affiliate serves as investment advisor (i.e., affiliated Underlying Funds). Such investments in the Underlying Funds could create a conflict of interest for the Advisor in managing the Fund’s assets. By investing in the Fund, you will indirectly bear fees and expenses of the Underlying Funds in addition to the Fund’s direct fees and expenses.

Risk [Text Block] rr_RiskTextBlock High-Yield Debt Securities Risk: High-yield debt securities or “junk bonds” are debt securities rated below investment grade by an NRSRO. Junk bonds are subject to greater credit risk than higher-grade securities, have a greater risk of default and are considered speculative. Issuers of junk bonds are more likely to experience financial difficulties that may impair their ability to make principal and interest payments.
Service Shares Prospectus | GuidePath(R) Conservative Allocation Fund | Small And Medium Capitalization Company Risk Member  
Prospectus [Line Items] rr_ProspectusLineItems  
Risk [Text Block] rr_RiskTextBlock Small and Medium Capitalization Company Risk: Small and medium capitalization companies often have narrower markets, fewer products or services to offer and more limited managerial and financial resources than do larger, more established companies. As a result, their performance can be more volatile, and they face a greater risk of business failure, which could increase the volatility and risk of loss of the Fund’s assets.
Service Shares Prospectus | GuidePath(R) Conservative Allocation Fund | Derivatives Risk Member  
Prospectus [Line Items] rr_ProspectusLineItems  
Risk [Text Block] rr_RiskTextBlock Derivatives Risk: A derivative is an instrument with a value based on the performance of an underlying currency, security, index or other reference asset. The use of derivatives involves risks different from, or greater than, the risks associated with investing in more traditional investments. Derivatives involve costs, may create leverage, and may be illiquid, volatile, and difficult to value. The Fund may not be able to close out or sell a derivative position at a particular time or at an anticipated price. The use of derivatives could also result in a loss if the counterparty to the transaction does not perform as promised, including because of such counterparty’s bankruptcy or insolvency. The investment results achieved by the use of derivatives by the Fund may not match or fully offset changes in the value of the underlying currency, security, index or other reference asset that it was attempting to hedge or the investment opportunity the Fund was attempting to pursue.
Service Shares Prospectus | GuidePath(R) Conservative Allocation Fund | Debt/Fixed Income Securities Risk Member  
Prospectus [Line Items] rr_ProspectusLineItems  
Risk [Text Block] rr_RiskTextBlock Debt/Fixed Income Securities Risk: An increase in interest rates typically causes a fall in the value of the debt securities in which the Fund may invest. Conversely, very low or negative interest rates may heighten the Fund's susceptibility to interest rate risk and diminish yield and performance.The value of your investment in the Fund may change in response to changes in the credit ratings of the debt securities in the Fund's portfolio. Moreover, rising interest rates or lack of market participants may lead to decreased liquidity in the bond and loan markets, making it more difficult for the Fund to sell its holdings at a time when the Fund's manager might wish to sell. Lower rated securities ("junk bonds") are generally subject to greater risk of loss of your money than higher rated securities. Issuers may (increase) decrease prepayments of principal when interest rates (fall) increase, affecting the maturity of the debt security and causing the value of the security to decline. To the extent the Fund or an Underlying Fund invests in derivatives tied to fixed income markets, the Fund or Underlying Fund may be more substantially exposed to these risks than a fund that does not invest in derivatives.
Service Shares Prospectus | GuidePath(R) Conservative Allocation Fund | Credit Risk Member

Risk [Text Block] rr_RiskTextBlock U.S. Government Agency Obligations Risk: Government agency obligations have different levels of credit support and, therefore, different degrees of credit risk. Some securities issued by agencies and instrumentalities of the U.S. Government are supported by the full faith and credit of the United States, but others are neither insured nor guaranteed by the U.S. Government. The U.S. Department of the Treasury has the authority to provide financial support to these debt obligations, but no assurance can be given that the U.S. Government will do so.

Risk [Text Block] rr_RiskTextBlock Commodities Risk: The Fund’s investment in commodity-linked investments and other commodity/natural resource-related securities may subject the Fund to greater volatility than investments in traditional securities. Commodity-linked investments may have a substantial risk of loss with respect to both principal and interest, and their returns may deviate significantly from the return of the underlying commodity, instruments, or measures. The ability of the Fund to invest in commodity-linked investments without exposing the Fund to Fund-level tax is limited under the Internal Revenue Code of 1986, as amended.

The risks of owning an ETF generally reflect the risks of owning the underlying securities held by the ETF, although a lack of liquidity in an ETF could result in it being more volatile. In addition, ETF shares may trade at a premium or discount relative to their net asset value. ETFs have management fees and other expenses which the Fund will indirectly bear.

The Fund could also lose money in connection with securities lending transactions if it does not recover the loaned securities and/or the value of the collateral falls, including the value of investments made with cash collateral. Securities lending also may have certain adverse tax consequences. The Fund is not obligated to engage in securities lending, and may discontinue its securities lending activities at any time.

Strategy Narrative [Text Block] rr_StrategyNarrativeTextBlock
In seeking to maximize total return, under normal circumstances, the Fund’s assets are allocated into a diversified portfolio consisting of domestic and international equity securities (including American Depositary Receipts (“ADRs”) and Global Depositary Receipts (“GDRs”)), domestic and international fixed income securities, exchange-traded funds (“ETFs”), mutual funds and cash equivalent money market securities. The Fund’s allocation to individual securities may range from 0% to 90% of the Fund’s assets.
The asset classes in which the Fund may invest include growth and value stocks, equity securities from developed and emerging international markets, commodity-related securities and domestic and international real estate securities, corporate bonds, mortgage- backed or asset-backed securities, securities issued by the U.S. and foreign governments or their agencies and instrumentalities, and higher-yielding bonds (sometimes referred to as “junk bonds”), including emerging market debt. The Fund may invest in debt obligations of any maturity. A significant portion of the Fund’s fixed income allocation may be in non-investment grade fixed income investments with varying maturities, but these allocations may vary significantly over time.
The Fund may allocate assets to various fixed income and equity securities and sectors. Using this type of strategy, the Fund seeks to tactically avoid risk by reducing exposure to unattractive sectors at the appropriate times, while also increasing exposure to attractive sectors on a timely basis.
The Fund may invest in investment companies (collectively, referred to herein as “Underlying Funds”) when AssetMark, Inc. (“AssetMark”
or the “Advisor”) believes that investing in Underlying Funds would provide the Fund with an efficient means of creating exposure to a broad range of securities. The Fund’s allocation to Underlying Funds may range from 10% to 100% of the Fund’s assets. The Fund may also invest in other exchange-traded products, such as exchange-traded notes (“ETNs”). The ETFs and ETNs in which the Fund invests may include inverse, leveraged, and inverse-leveraged ETFs and ETNs. Inverse ETFs and ETNs are designed to correlate inversely with the performance of an index. Leveraged and inverse-leveraged ETFs and ETNs seek investment results that correspond to two or more times the performance of an index or inverse of the performance of an index, respectively. By investing in the Fund, you will indirectly bear fees and expenses of Underlying Funds in which the Fund may invest in addition to the Fund’s direct fees and expenses. In order to obtain exposure to certain markets, asset classes or active management styles, the Fund may buy Underlying Funds managed by the Advisor or its affiliates, which, in turn, invest in various securities, including ETFs. The Fund may invest in Underlying Funds that use alternative strategies (e.g., long/short strategies - equity and fixed income, market- neutral strategies, and absolute return/global macro strategies) and/or use derivatives for risk management purposes or as part of their investment strategies. An Underlying Fund may use derivatives to earn income and enhance returns, to manage or adjust its risk profile, to replace more traditional direct investments, or to obtain exposure to certain markets.
The Advisor’s asset allocation decisions will be based on different factors and analytical approaches, including tactical volatility managed asset allocation approaches developed by various research providers selected by the Advisor. The Advisor may utilize a combination of internal and external research constructing the Fund’s portfolio.
The Fund’s asset allocation mix among equity, fixed income and cash equivalent money market securities is intended to change frequently over time. The Fund does not have a set target asset allocation mix among equities, fixed income securities and cash equivalent investments. If the Advisor believes that the stock market conditions are unfavorable or overvalued, it may significantly increase the allocation to more defensive asset classes such as fixed income or cash equivalent securities. The Advisor also has broad latitude to allocate assets to equity securities in pursuit of perceived opportunities for additional return. Based on these judgments, the Fund’s asset allocation mix may significantly change over time in response to opportunities as they are identified.
The Fund lends its portfolio securities to seek to generate additional income.

Certain alternative strategies involve the risk that a
counterparty to a transaction will not perform as promised, which could result in losses to the Fund. Furthermore, alternative strategies may employ leverage, involve extensive short positions and/or focus on narrow segments of the market, which may magnify the overall risks and volatility associated with such investments.

Prospectus [Line Items] rr_ProspectusLineItems  
Risk [Text Block] rr_RiskTextBlock Investments in Underlying Funds Risk: To the extent that the Fund allocates a substantial portion of its assets to Underlying Funds, the ability of the Fund to meet its investment objective will depend on the ability of the Underlying Funds to meet their investment objectives. There can be no assurance that either the Fund or the Underlying Funds will achieve their investment objectives. Additionally, the Fund may invest in other investment companies for which the Advisor or an affiliate serves as investment advisor (i.e., affiliated Underlying Funds). Such investments in the Underlying Funds could create a conflict of interest for the Advisor in managing the Fund’s assets. By investing in the Fund, you will indirectly bear fees and expenses of the Underlying Funds in addition to the Fund’s direct fees and expenses.

Service Shares Prospectus | GuidePath(R) Tactical Allocation Fund | Foreign Securities Risk Member  
Prospectus [Line Items] rr_ProspectusLineItems  
Risk [Text Block] rr_RiskTextBlock Foreign Securities Risk: The risks of investing in foreign securities (including ADRs and GDRs) can increase the potential for losses in the Fund and may include currency fluctuations, political and economic instability, less government regulation, less publicly available information, limited trading markets, differences in financial reporting standards, fewer protections for passive investors and less stringent regulation of securities markets.
Service Shares Prospectus | GuidePath(R) Tactical Allocation Fund | Foreign Exchange Trading Risk Member  
Prospectus [Line Items] rr_ProspectusLineItems  
Risk [Text Block] rr_RiskTextBlock Foreign Exchange Trading Risk: The trading of foreign currencies directly generates risks separate from those faced from the risks of inactive or indirect exposures to non-dollar denominated instruments, insofar as the Fund may experience a loss from the buying and selling of currencies without any related exposure to non-dollar-denominated assets.
Service Shares Prospectus | GuidePath(R) Tactical Allocation Fund | High-Yield Debt Securities Risk Member  
Prospectus [Line Items] rr_ProspectusLineItems  
Risk [Text Block] rr_RiskTextBlock High-Yield Debt Securities Risk: High-yield debt securities or “junk bonds” are debt securities rated below investment grade by an NRSRO. Junk bonds are subject to greater credit risk than higher-grade securities, have a greater risk of default and are considered speculative. Issuers of junk bonds are more likely to experience financial difficulties that may impair their ability to make principal and interest payments.
Service Shares Prospectus | GuidePath(R) Tactical Allocation Fund | Leveraged And Inverse ETF/ETN Risk Member  
Prospectus [Line Items] rr_ProspectusLineItems  
Risk [Text Block] rr_RiskTextBlock Leveraged and Inverse ETF/ETN Risk: Inverse ETFs/ETNs generally use derivatives and short sales that, in combination, are designed to produce returns that move in the opposite direction of the indices they track. To the extent the Fund invests in ETFs/ETNs that seek to provide investment results that are the inverse of the performance of an underlying index, the Fund will indirectly be subject to the risk that the performance of such ETF/ETN will fall as the performance of that ETF or ETN’s benchmark rises, a result that is the opposite from traditional mutual funds. The Fund’s use of leveraged and inverse-leveraged ETFs and ETNs has the economic effect of creating financial leverage. Financial leverage magnifies exposure to the swings in prices of an asset class and results in increased volatility, which means the Fund will have the potential for greater gains, as well as the potential for greater losses, than if the Fund had not invested in these instruments at all.
Service Shares Prospectus | GuidePath(R) Tactical Allocation Fund | Small And Medium Capitalization Company Risk Member  
Prospectus [Line Items] rr_ProspectusLineItems  
Risk [Text Block] rr_RiskTextBlock Small and Medium Capitalization Company Risk: Small and medium capitalization companies often have narrower markets, fewer products or services to offer and more limited managerial and financial resources than do larger, more established companies. As a result, their performance can be more volatile, and they face a greater risk of business failure, which could increase the volatility and risk of loss of the Fund’s assets.
Service Shares Prospectus | GuidePath(R) Tactical Allocation Fund | Derivatives Risk Member  
Prospectus [Line Items] rr_ProspectusLineItems  
Risk [Text Block] rr_RiskTextBlock Derivatives Risk: A derivative is an instrument with a value based on the performance of an underlying currency, security, index or other reference asset. The use of derivatives involves risks different from, or greater than, the risks associated with investing in more traditional investments. Derivatives involve costs, may create leverage, and may be illiquid, volatile, and difficult to value. The Fund may not be able to close out or sell a derivative position at a particular time or at an anticipated price. The use of derivatives could also result in a loss if the counterparty to the transaction does not perform as promised, including because of such counterparty’s bankruptcy or insolvency. The investment results achieved by the use of derivatives by the Fund may not match or fully offset changes in the value of the underlying currency, security, index or other reference asset that it was attempting to hedge or the investment opportunity the Fund was attempting to pursue.
Service Shares Prospectus | GuidePath(R) Tactical Allocation Fund | Debt/Fixed Income Securities Risk Member  
Prospectus [Line Items] rr_ProspectusLineItems  
Risk [Text Block] rr_RiskTextBlock Debt/Fixed Income Securities Risk: An increase in interest rates typically causes a fall in the value of the debt securities in which the Fund may invest. Conversely, very low or negative interest rates may heighten the Fund's susceptibility to interest rate risk and diminish yield and performance.The value of your investment in the Fund may change in response to changes in the credit ratings of the debt securities in the Fund's portfolio. Moreover, rising interest rates or lack of market participants may lead to decreased liquidity in the bond and loan markets, making it more difficult for the Fund to sell its holdings at a time when the Fund's manager might wish to sell. Lower rated securities ("junk bonds") are generally subject to greater risk of loss of your money than higher rated securities. Issuers may (increase) decrease prepayments of principal when interest rates (fall) increase, affecting the maturity of the debt security and causing the value of the security to decline. To the extent the Fund or an Underlying Fund invests in derivatives tied to fixed income markets, the Fund or Underlying Fund may be more substantially exposed to these risks than a fund that does not invest in derivatives.
Service Shares Prospectus | GuidePath(R) Tactical Allocation Fund | Credit Risk Member  
Prospectus [Line Items] rr_ProspectusLineItems  
Risk [Text Block] rr_RiskTextBlock Credit Risk: Individual issues of fixed income securities may be subject to the credit risk of the issuer. This means that the issuer of a fixed income security, or in the case of a municipal security, the underlying municipality, may experience financial problems, causing it to be unable to meet its payment obligations.
Service Shares Prospectus | GuidePath(R) Tactical Allocation Fund | U.S. Government Agency Obligations Risk Member  
Prospectus [Line Items] rr_ProspectusLineItems  
Risk [Text Block] rr_RiskTextBlock U.S. Government Agency Obligations Risk: Government agency obligations have different levels of credit support and, therefore, different degrees of credit risk. Some securities issued by agencies and instrumentalities of the U.S. Government are supported by the full faith and credit of the United States, but others are neither insured nor guaranteed by the U.S. Government. The U.S. Department of the Treasury has the authority to provide financial support to these debt obligations, but no assurance can be given that the U.S. Government will do so.
Service Shares Prospectus | GuidePath(R) Tactical Allocation Fund | Commodities Risk Member  
Prospectus [Line Items] rr_ProspectusLineItems  
Risk [Text Block] rr_RiskTextBlock Commodities Risk: The Fund’s investment in commodity-linked investments and other commodity/natural resource-related securities may subject the Fund to greater volatility than investments in traditional securities. Commodity-linked investments may have a substantial risk of loss with respect to both principal and interest, and their returns may deviate significantly from the return of the underlying commodity, instruments, or measures. The ability of the Fund to invest in commodity-linked investments without exposing
the Fund to Fund-level tax is limited under the Internal Revenue Code of 1986, as amended.
Service Shares Prospectus | GuidePath(R) Tactical Allocation Fund | Real Estate Risk Member  
Prospectus [Line Items] rr_ProspectusLineItems  
Risk [Text Block] rr_RiskTextBlock Real Estate Risk: The value of real estate-linked derivative instruments and other real estate-related securities such as real estate investment trusts (“REITs”) may be affected by risks similar to those associated with direct ownership of real estate, in addition to the risks of poor performance by a REIT’s manager, changes to tax laws, and failure by the REIT to qualify for favorable treatment. To the extent the Fund invests in REITs, you will indirectly bear fees and expenses of the underlying REITs in addition to the Fund’s direct fees and expenses. REITs may have limited diversification and may not exhibit the same (or any) correlation with inflation that real estate or other real estate securities exhibit.
Service Shares Prospectus | GuidePath(R) Tactical Allocation Fund | Portfolio Turnover Risk Member  
Prospectus [Line Items] rr_ProspectusLineItems  
Risk [Text Block] rr_RiskTextBlock Portfolio Turnover Risk: Depending on market and other conditions, the Fund may experience a high portfolio turnover, which may result in higher brokerage costs and transaction costs (which could reduce investment returns). Distributions of net short-term capital gains are taxable as ordinary income when Fund shares are held in a taxable account. A fund with a high portfolio turnover rate (a measure of how frequently assets within a fund are bought and sold) is more likely to generate short-term capital gains than a fund with a low portfolio turnover rate.
Service Shares Prospectus | GuidePath(R) Tactical Allocation Fund | Exchange-Traded Funds Risk Member  
Prospectus [Line Items] rr_ProspectusLineItems  
Risk [Text Block] rr_RiskTextBlock Exchange-Traded Funds Risk: An ETF may represent a portfolio of securities, or may use derivatives in pursuit of its stated objective. The risks of owning an ETF generally reflect the risks of owning the underlying securities held by the ETF, although a lack of liquidity in an ETF could result in it being more volatile. In addition, ETF shares may trade at a premium or discount relative to their net asset value. ETFs have management fees and other expenses which the Fund will indirectly bear.
Service Shares Prospectus | GuidePath(R) Tactical Allocation Fund | Securities Lending Risk Member  
Prospectus [Line Items] rr_ProspectusLineItems  
Risk [Text Block] rr_RiskTextBlock Securities Lending Risk: When the Fund lends its portfolio securities, the Fund is subject to the risk that the borrower may fail to return the securities in a timely manner or at all, resulting in a loss to the Fund and/or a delay in recovering the loaned securities. The Fund could also lose money in connection with securities lending transactions if it does not recover the loaned securities and/or the value of the collateral falls, including the value of investments made with cash collateral. Securities lending also may have certain adverse tax consequences. The Fund is not obligated to engage in securities lending, and may discontinue its securities lending activities at any time.

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. The Fund does not pay transaction costs when buying and selling shares of other mutual funds, however, the underlying funds pay transaction costs when buying and selling securities for their portfolio. 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 53.14% of the average value of its portfolio.

Strategy [Heading] rr_StrategyHeading Principal Investment Strategies of the Fund
Strategy Narrative [Text Block] rr_StrategyNarrativeTextBlock
The Fund operates as a fund of funds, investing primarily in registered mutual funds, including exchange-traded funds (“ETFs”). The funds in which the Fund may invest are referred to herein as the “Underlying Funds.” AssetMark, Inc. (“AssetMark” or the “Advisor”) believes that investing in Underlying Funds provides the Fund with an efficient means of creating a portfolio that provides investors with indirect exposure to a broad range of securities. By investing in the Fund, you will indirectly bear fees and expenses of the Underlying Funds in addition to the Fund’s direct fees and expenses. In order to obtain exposure to certain markets, asset classes or active management styles, the
Fund may buy Underlying Funds managed by the Advisor or its affiliates, which, in turn, invest in various securities, including ETFs. The Fund may also invest directly in securities and other exchange-traded products, such as exchange-traded notes (“ETNs”).
The Advisor’s asset allocation decisions will be based on different factors and analytical approaches, derived from absolute return asset allocation approaches developed by various research providers and considered by the Advisor in constructing the Fund’s portfolio. The research providers’ absolute return asset allocation approaches typically utilize fundamental and quantitative analyses of global market and economic conditions and assumptions regarding risks and returns. The Advisor seeks to create a portfolio that is optimized to seek to achieve consistent absolute positive returns over time regardless of the market environment.
In pursuing the Fund’s objective, the Fund invests, either directly or indirectly via the Underlying Funds, in fixed income or equity-oriented investments across global markets, using varying active asset allocation strategies among different security types, asset classes, yield and duration, valuation analyses, and currency exposure considerations.
The Fund may utilize an absolute return asset allocation strategy that builds on a foundation of alternative investments, such as long/short equity funds that seek a modest positive return from equity investments, that attempts to stay insulated from general stock market volatility, combined with opportunistic equity and fixed income investments strategically selected to enhance returns. The Fund may invest in Underlying Funds that use alternative strategies and/or use derivatives for risk management purposes or engage in significant use of derivatives as part of their investment strategies. The alternative strategies used by Underlying Funds may include, among others, long/short strategies – equity and fixed income, market-neutral strategies, absolute return/global macro strategies, and risk premium strategies, including market risk transfer strategies, alternative (marketplace) lending and real estate, reinsurance and commodity-linked derivatives. An Underlying Fund may use derivatives to earn income and enhance returns, to manage or adjust the risk profile of the Underlying Fund, to replace more traditional direct investments, or to obtain exposure to certain markets or asset classes, including digital assets such as bitcoin.
The Fund may also utilize absolute return asset allocation strategies that allocate assets to various fixed income instruments and sectors using various passive index-oriented ETFs focusing on instruments such as U.S. Government bonds and notes, corporate bonds, bank loans, mortgage-related securities and asset-backed securities, inflation-protected debt securities, corporate bonds of various quality levels and maturity/duration, and cash equivalent investments. Using this type of strategy, the Fund seeks to tactically avoid risk by reducing exposure at the appropriate times, while increasing exposure to attractive sectors on a timely basis.
The Fund lends its portfolio securities to seek to generate additional income.

Risk [Text Block] rr_RiskTextBlock Fund of Funds Risk: The Fund is subject to fund of funds risk, which means that the ability of the Fund to meet its investment objective is directly related to the ability of the Underlying Funds to meet their investment objectives.  There can be no assurance that either the Fund or the Underlying Funds will achieve their investment objectives. Additionally, each Fund may invest in other investment companies for which the Advisor or an affiliate serves as investment advisor (i.e., affiliated Underlying Funds). Such investments in the Underlying Funds could create a conflict of interest for the Advisor in managing the Fund’s assets. By investing in the Fund, you will indirectly bear fees and expenses of the Underlying Funds in addition to the Fund’s direct fees and expenses.

Certain alternative strategies involve the risk that a counterparty to a transaction will not perform as promised, which could result in losses to the Fund. Furthermore, alternative strategies may employ leverage, involve extensive short positions and/or focus on narrow segments of the market, which may magnify the overall risks and volatility associated with such investments.

Risk [Text Block] rr_RiskTextBlock High-Yield Debt Securities Risk: High-yield debt securities or “junk bonds” are debt securities rated below investment grade by an NRSRO. Junk bonds are subject to greater credit risk than higher-grade securities, have a greater risk of default and are considered speculative. Issuers of junk bonds are more likely to experience financial difficulties that may impair their ability to make principal and interest payments.
Service Shares Prospectus | GuidePath(R) Absolute Return Allocation Fund | Derivatives Risk Member  
Prospectus [Line Items] rr_ProspectusLineItems  
Risk [Text Block] rr_RiskTextBlock Derivatives Risk: A derivative is an instrument with a value based on the performance of an underlying currency, security, index or other reference asset. The use of derivatives involves risks different from, or greater than, the risks associated with investing in more traditional investments. Derivatives involve costs, may create leverage, and may be illiquid, volatile, and difficult to value. The Fund may not be able to close out or sell a derivative position at a particular time or at an anticipated price. The use of derivatives could also result in a loss if the counterparty to the transaction does not perform as promised, including because of such counterparty’s bankruptcy or insolvency. The investment results achieved by the use of derivatives by the Fund may not match or fully offset changes in the value of the underlying currency, security, index or other reference asset that it was attempting to hedge or the investment opportunity the Fund was attempting to pursue.
Service Shares Prospectus | GuidePath(R) Absolute Return Allocation Fund | Debt/Fixed Income Securities Risk Member  
Prospectus [Line Items] rr_ProspectusLineItems  
Risk [Text Block] rr_RiskTextBlock Debt/Fixed Income Securities Risk: An increase in interest rates typically causes a fall in the value of the debt securities in which the Fund may invest. Conversely, very low or negative interest rates may heighten the Fund's susceptibility to interest rate risk and diminish yield and performance.The value of your investment in the Fund may change in response to changes in the credit ratings of the debt securities in the Fund's portfolio. Moreover, rising interest rates or lack of market participants may lead to decreased liquidity in the bond and loan markets, making it more difficult for the Fund to sell its holdings at a time when the Fund's manager might wish to sell. Lower rated securities ("junk bonds") are generally subject to greater risk of loss of your money than higher rated securities. Issuers may
(increase) decrease prepayments of principal when interest rates (fall) increase, affecting the maturity of the debt security and causing the value of the security to decline. To the extent the Fund or an Underlying Fund invests in derivatives tied to fixed income markets, the Fund or Underlying Fund may be more substantially exposed to these risks than a fund that does not invest in derivatives.
Service Shares Prospectus | GuidePath(R) Absolute Return Allocation Fund | Bitcoin Investments Risk Member  
Prospectus [Line Items] rr_ProspectusLineItems  
Risk [Text Block] rr_RiskTextBlock Bitcoin Investments Risk: Certain Underlying Funds may invest in bitcoin, bitcoin futures contracts and options on bitcoin futures contracts (or options on ETFs that invest in bitcoin or bitcoin futures contracts). Bitcoin operates without central authority (such as a bank) and is not backed by any government, corporation, or other entity. Bitcoin is not generally accepted as legal tender. Regulation of bitcoin and other cryptocurrencies is still developing. Federal, state and/or foreign governments may restrict the development, use, or exchange of bitcoin. The market price of bitcoin has historically been highly volatile. The price of bitcoin could fall sharply (potentially to zero) for various reasons, including, but not limited to, regulatory changes, issues impacting the bitcoin network, events involving entities that facilitate transactions in bitcoin, or changes in user preferences in favor of alternative cryptocurrencies. Furthermore, events that impact other cryptocurrencies may lead to a decline in the value of bitcoin. Cryptocurrency exchanges and other trading venues on which cryptocurrencies trade are relatively new and, in most cases, largely unregulated. Accordingly, cryptocurrency exchanges may be more exposed to fraud and failure than established, regulated exchanges for securities, derivatives and other currencies. Cryptocurrency exchanges are also subject to cyber security risks. Cryptocurrency exchanges have experienced cyber security breaches in the past and may be breached in the future, which could result in the theft and/or loss of bitcoin and impact the value of bitcoin futures. Furthermore, cyber security events, legal or regulatory actions, fraud, and technical glitches, may cause a cryptocurrency exchange to shut down temporarily or permanently, which may also affect the value of bitcoin and/or bitcoin futures.
Shares of ETFs that hold bitcoin and/or bitcoin futures may trade in the secondary market at a premium to or discount from their NAVs, and an Underlying Fund may purchase or sell shares of bitcoin futures ETFs at prices above or below such NAVs. Because the market price of ETF shares depends in part on the demand in the market for the shares, as well as on the value of the ETF’s component assets, and because the market price of ETF shares is subject to tracking error, the market price of a bitcoin futures ETF may be more volatile than the underlying bitcoin futures contracts in which the bitcoin futures ETF invests. In addition, an Underlying Fund may not be able to liquidate bitcoin futures ETF holdings at the time or price desired, which may adversely impact the Underlying Fund’s performance and in turn, the value of the Fund’s investment. Furthermore, there may be times when the exchange halts trading in the shares of a bitcoin futures ETF, in which case the Underlying Fund would be unable to sell them until trading is resumed.
Service Shares Prospectus | GuidePath(R) Absolute Return Allocation Fund | Bitcoin Market Volatility Risk Member  
Prospectus [Line Items] rr_ProspectusLineItems  
Risk [Text Block] rr_RiskTextBlock Bitcoin Market Volatility Risk: Bitcoin has historically exhibited higher price volatility than more traditional asset classes. For instance, the two largest historical drawdowns were during the period from June 8, 2011 to November 18, 2011 and the period from December 17, 2017 to December 14, 2018, when bitcoin experienced a decline of roughly 93% and 84%, respectively. The price of bitcoin and therefore the value of an investment in the Underlying Fund may be negatively impacted by unfavorable investor sentiment resulting from recent developments in the broader digital asset industry, including the fallout from the recent insolvency proceedings of digital asset market participants such as digital asset exchange FTX Trading Ltd., et al. (and its affiliated hedge fund Alameda Research LLC), digital asset hedge fund Three Arrows Capital and digital asset lenders Celsius Network LLC, et al., Voyager Digital Ltd., et al. and BlockFi Inc. The value of bitcoin and, therefore, of an Underlying Fund’s bitcoin strategy, could decline rapidly, including to zero, which would adversely affect the Underlying Fund’s NAV per share.
Service Shares Prospectus | GuidePath(R) Absolute Return Allocation Fund | Insurance-Linked Securities Risk Member  
Prospectus [Line Items] rr_ProspectusLineItems  
Risk [Text Block] rr_RiskTextBlock Insurance-Linked Securities Risk: The principal risk of investments in insurance-linked securities is that a triggering event (which could include a natural disaster like an earthquake or tornado or a commercial or industrial accident like an aviation disaster or oil spill) occurs, resulting an Underlying Fund losing all or a significant portion of the principal it has invested in the security and the right to additional interest payments with respect to the security. If multiple triggering events occur that impact a significant portion of the portfolio of the Underlying Fund, the Underlying Fund could suffer substantial losses and an investor will lose money. Event-linked or catastrophe bonds carry large uncertainties and major risk exposures to adverse conditions. Certain reinsurance investments may be difficult to value. There is no way to accurately predict whether a triggering event will occur and, because of this significant uncertainty, insurance-linked securities carry a high degree of risk.
Service Shares Prospectus | GuidePath(R) Absolute Return Allocation Fund | Marketplace Loan Risk Member  
Prospectus [Line Items] rr_ProspectusLineItems  
Risk [Text Block] rr_RiskTextBlock Marketplace Loan Risk: Investments by Underlying Funds in loans sourced through marketplace lending platforms are subject to additional risks than those applicable to investments in loans generally. If a borrower is unable or fails to make payments on a loan for any reason, an Underlying Fund may not have direct recourse against the borrower or may be otherwise limited in its ability to directly enforce its rights under the loan, whether through the borrower or the marketplace lending platform through which the loan was originated. Borrowings obtained through marketplace lending platforms may not limit borrowers from incurring additional debt which may impair the borrower’s ability to repay interest and principal of the original loan. Default history for alternative lending platforms is limited. Future defaults may be higher than historical defaults and the timing of defaults may vary significantly from historical observations. An Underlying Fund may have limited knowledge about the underlying loans to which it has exposure and is dependent upon the platform for information regarding the loans and borrowers’ credit information. Such information may be incomplete, inaccurate or outdated and may, therefore, not accurately reflect the borrowers’ actual creditworthiness. Disruptions in the business of a platform may also negatively impact the value of loans sourced through that platform. Investments in loans sourced through a marketplace lending platform may also be negatively impacted if the platform or a third-party service provider becomes unable or unwilling to fulfill its obligations in servicing the loans.
Service Shares Prospectus | GuidePath(R) Absolute Return Allocation Fund | Subordinated Real Estate Loan Risk Member  
Prospectus [Line Items] rr_ProspectusLineItems  
Risk [Text Block] rr_RiskTextBlock Subordinated Real Estate Loan Risk: An Underlying Fund may acquire or originate subordinated real estate loans secured by single family rental properties, including mezzanine loans in the form of subordinated loans secured by a pledge of the ownership interests of either the entity owning such properties or the entity that owns the interest in the entity owning such properties. In the event a borrower
defaults on a subordinated loan and lacks sufficient assets to satisfy such loan, the Underlying Fund may suffer a loss of principal or interest. In the event a borrower declares bankruptcy, the Underlying Fund may not have full recourse to the assets of the borrower, or the assets of the borrower may not be sufficient to satisfy the loan. If a borrower defaults on a loan owned by the Underlying Fund or on debt senior to such loan, or in the event of a borrower bankruptcy, such loan will be satisfied only after the senior debt is paid in full. These types of investments may become unsecured as a result of foreclosure by the senior lender.

Prospectus [Line Items] rr_ProspectusLineItems  
Risk [Text Block] rr_RiskTextBlock U.S. Government Agency Obligations Risk: Government agency obligations have different levels of credit support and, therefore, different degrees of credit risk. Some securities issued by agencies and instrumentalities of the U.S. Government are supported by the full faith and credit of the United States, but others are neither insured nor guaranteed by the U.S. Government. The U.S. Department of the Treasury has the authority to provide financial support to these debt obligations, but no assurance can be given that the U.S. Government will do so.

Risk [Text Block] rr_RiskTextBlock Real Estate Risk: The value of real estate-linked derivative instruments and other real estate-related securities such as real estate investment trusts (“REITs”) may be affected by risks similar to those associated with direct ownership of real estate, in addition to the risks of poor performance by a REIT’s manager, changes to tax laws, and failure by the REIT to qualify for favorable treatment. To the extent the Fund invests in REITs, you will indirectly bear fees and expenses of the underlying REITs in addition to the Fund’s direct fees and expenses. REITs may have limited diversification and may not exhibit the same (or any) correlation with inflation that real estate or other real estate securities exhibit.

Service Shares Prospectus | GuidePath(R) Absolute Return Allocation Fund | Loan Risk Member  
Prospectus [Line Items] rr_ProspectusLineItems  
Risk [Text Block] rr_RiskTextBlock Loan Risk: Loans are subject to risk of loss as a result of borrower default, sensitivity to interest rate and economic changes, valuation difficulties and potential decreased liquidity to a greater extent than other types of investments. The value of any collateral securing a loan may decline, be insufficient to meet the borrower’s obligations, or be difficult or costly to liquidate. It may take longer than 7 days for investments in loans to settle, which may adversely affect an Underlying Fund’s ability to timely honor redemptions. Newly originated variable rate securities (including reissuances and restructured loans) may possess lower levels of credit document protections than has historically been the case. Accordingly, in the event of default the Fund may experience lower levels of recoveries than has historically been the norm.
Service Shares Prospectus | GuidePath(R) Absolute Return Allocation Fund | Portfolio Turnover Risk Member  
Prospectus [Line Items] rr_ProspectusLineItems  
Risk [Text Block] rr_RiskTextBlock Portfolio Turnover Risk: Depending on market and other conditions, the Fund may experience a high portfolio turnover, which may result in higher brokerage costs and transaction costs (which could reduce investment returns). Distributions of net short-term capital gains are taxable as ordinary income when Fund shares are held in a taxable account. A fund with a high portfolio turnover rate (a measure of how frequently assets within a fund are bought and sold) is more likely to generate short-term capital gains than a fund with a low portfolio turnover rate.

The risks of owning an ETF generally reflect the risks of owning the underlying securities held by the ETF, although a lack of liquidity in an ETF could result in it being more volatile. In addition, ETF shares may trade at a premium or discount relative to their net asset value. ETFs have management fees and other expenses which the Fund will indirectly bear.

The Fund could also lose money in connection with securities lending transactions if it does not recover the loaned securities and/or the value of the collateral falls, including the value of investments made with cash collateral. Securities lending also may have certain adverse tax consequences. The Fund is not obligated to engage in securities lending, and may discontinue its securities lending activities at any time.

Portfolio Turnover [Text Block] rr_PortfolioTurnoverTextBlock
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.  The Fund does not pay transaction costs when buying and selling shares of other mutual funds, however, the underlying funds pay transaction costs when buying and selling securities for their portfolio. 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 27.54% of the average value of its portfolio.

Strategy [Heading] rr_StrategyHeading Principal Investment Strategies of the Fund
Strategy Narrative [Text Block] rr_StrategyNarrativeTextBlock
The Fund operates as a fund of funds, investing primarily in registered mutual funds (both actively and passively managed) and exchange-traded funds (“ETFs”). The funds in which the Fund may invest are referred to herein as the “Underlying Funds.” AssetMark, Inc. (“AssetMark” or the “Advisor”) believes that investing in Underlying Funds provides the Fund with an efficient means of creating a portfolio that provides investors with indirect exposure to a broad range of asset classes. By investing in the Fund, you will indirectly bear fees and expenses of the Underlying Funds in addition to the Fund’s direct fees and expenses. In order to obtain exposure to certain markets, asset classes or active management styles, the Fund may buy Underlying Funds managed by the Advisor or its affiliates, which, in turn, invest in various securities, including ETFs. The Fund may also invest directly in securities and other exchange-traded products, such as exchange-traded notes (“ETNs”).
The Fund has broad flexibility to allocate its assets among a wide variety of debt and equity securities and real estate investment trusts (“REITs”). As part of its principal investment strategy or for temporary defensive purposes, any portion of the Fund’s assets may also be invested in cash and cash equivalents. The Fund may invest in such instruments directly or indirectly through its investment in Underlying Funds. The Fund’s approach is flexible and allows the Advisor to shift the Fund’s allocations in response to changing market conditions. As a result, the Fund may at times be invested in a single or multiple asset classes, markets or sectors. The Fund may also take positions in various global currencies and may hold positions in instruments that are denominated in currencies other than the U.S. dollar.
The Advisor’s asset allocation decisions are based on different factors and analytical approaches, derived from asset allocation approaches developed by various research providers and considered by the Advisor in constructing the Fund’s portfolio. In attempting to achieve the Fund’s investment objective, the Advisor monitors and adjusts the Fund’s asset allocations as necessary.
Under normal circumstances, the Fund will be expected to allocate between 40% and 80% of its assets to equity securities and investments that provide exposure to equity securities and between 20% to 60% of its assets to fixed income securities and investments that provide exposure to fixed income securities. Over time, the asset allocation mix may change as a result of changing capital market assumptions or short-term market opportunities. Under normal market conditions, the Fund will be expected to allocate approximately 60% of its assets to equity securities and investments that provide exposure to equity securities and 40% of its assets to fixed income securities and investments that provide exposure to fixed income securities, including cash equivalents.
The Fund’s fixed income allocation may include, but is not limited to, investments made directly or indirectly via the Underlying Funds in debt securities of governments, government agencies and supranational entities, debt securities of corporations, preferred stock, bank loans, convertible securities, mortgage- or asset-backed securities, inflation-linked securities and other securitized or collateralized debt obligations. The Fund’s fixed income allocation may also include higher-yielding bonds (sometimes referred to as “junk bonds”), including emerging market debt. It is possible that a significant portion of the Fund’s fixed income allocation may be invested, directly or indirectly, in non-investment grade fixed income investments with varying maturities.
The Fund may invest, directly or indirectly, in domestic and international equities (including American Depositary Receipts (“ADRs”) and Global Depositary Receipts (“GDRs”)). The Fund’s equity allocation may include investments made directly or indirectly via the Underlying Funds in both small- and large-capitalization companies and both growth and value stocks. The Fund’s equity allocation may also include equity securities from emerging international markets, and both domestic and international real estate securities.
The Fund may invest in Underlying Funds that use alternative strategies (e.g., long/short strategies – equity and fixed income, market-neutral strategies, and absolute return/global macro strategies) and/or use derivatives for risk management purposes or as part of their investment strategies. An Underlying Fund may use derivatives to earn income and enhance returns, to manage or adjust the risk and duration exposure profile of the Underlying Fund, to replace more traditional direct investments or to obtain exposure to certain markets, interest rates, sectors or individual issuers. The derivatives used by an Underlying Fund may allow the Underlying Fund to obtain net long or net negative (short) exposures to selected interest rates, countries, duration or credit risks. An Underlying Fund may also use derivatives to hedge or gain exposure to currencies.
The Fund lends its portfolio securities to seek to generate additional income.

Risk [Text Block] rr_RiskTextBlock Fund of Funds Risk: The Fund is subject to fund of funds risk, which means that the ability of the Fund to meet its investment objective is directly related to the ability of the Underlying Funds to meet their investment objectives.  There can be no assurance that either the Fund or the Underlying Funds will achieve their investment objectives. Additionally, each Fund may invest in other investment companies for which the Advisor or an affiliate serves as investment advisor (i.e., affiliated Underlying Funds). Such investments in the Underlying Funds could create a conflict of interest for the Advisor in managing the Fund’s assets. By investing in the Fund, you will indirectly bear fees and expenses of the Underlying Funds in addition to the Fund’s direct fees and expenses.

Risk [Text Block] rr_RiskTextBlock Interest Rate Risk: The market value of fixed income securities will fluctuate with changes in interest rates. For example, when interest rates rise, the market value of fixed income securities declines. If the market value of the Fund’s investments decreases, investors in the Fund may lose money. The Fund may face a heightened level of interest rate risk due to changes in general economic conditions, inflation and monetary policy, including interest rate changes by the Federal Reserve.

Certain alternative strategies involve the risk that a counterparty to a transaction will not perform as promised, which could result in losses to the Fund. Furthermore, alternative strategies may employ leverage, involve extensive short positions and/or focus on narrow segments of the market, which may magnify the overall risks and volatility associated with such investments.

Prospectus [Line Items] rr_ProspectusLineItems  
Risk [Text Block] rr_RiskTextBlock High-Yield Debt Securities Risk: High-yield debt securities or “junk bonds” are debt securities rated below investment grade by an NRSRO. Junk bonds are subject to greater credit risk than higher-grade securities, have a greater risk of default and are considered speculative. Issuers of junk bonds are more likely to experience financial difficulties that may impair their ability to make principal and interest payments.
Service Shares Prospectus | GuidePath(R) Multi-Asset Income Allocation Fund | Small And Medium Capitalization Company Risk Member  
Prospectus [Line Items] rr_ProspectusLineItems  
Risk [Text Block] rr_RiskTextBlock Small and Medium Capitalization Company Risk: Small and medium capitalization companies often have narrower markets, fewer products or services to offer and more limited managerial and financial resources than do larger, more established companies. As a result, their performance can be more volatile, and they face a greater risk of business failure, which could increase the volatility and risk of loss of the Fund’s assets.
Service Shares Prospectus | GuidePath(R) Multi-Asset Income Allocation Fund | Derivatives Risk Member  
Prospectus [Line Items] rr_ProspectusLineItems  
Risk [Text Block] rr_RiskTextBlock Derivatives Risk: A derivative is an instrument with a value based on the performance of an underlying currency, security, index or other reference asset. The use of derivatives involves risks different from, or greater than, the risks associated with investing in more traditional investments. Derivatives involve costs, may create leverage, and may be illiquid, volatile, and difficult to value. The Fund may not be able to close out or sell a derivative position at a particular time or at an anticipated price. The use of derivatives could also result in a loss if the counterparty to the transaction does not perform as promised, including because of such counterparty’s bankruptcy or insolvency. The investment results achieved by the use of derivatives by the Fund may not match or fully offset changes in the value of the underlying currency, security, index or other reference asset that it was attempting to hedge or the investment opportunity the Fund was attempting to pursue.
Service Shares Prospectus | GuidePath(R) Multi-Asset Income Allocation Fund | Debt/Fixed Income Securities Risk Member  
Prospectus [Line Items] rr_ProspectusLineItems  
Risk [Text Block] rr_RiskTextBlock Debt/Fixed Income Securities Risk: An increase in interest rates typically causes a fall in the value of the debt securities in which the Fund may invest. Conversely, very low or negative interest rates may heighten the Fund's susceptibility to interest rate risk and diminish yield and performance.The value of your investment in the Fund may change in response to changes in the credit ratings of the debt securities in the Fund's portfolio. Moreover, rising interest rates or lack of market participants may lead to decreased liquidity in the bond and loan markets, making it more difficult for the Fund to sell its holdings at a time when the Fund's manager might wish to sell. Lower rated securities ("junk bonds") are generally subject to greater risk of loss of your money than higher rated securities. Issuers may (increase) decrease prepayments of principal when interest rates (fall) increase, affecting the maturity of the debt security and causing the value of the security to decline. To the extent the Fund or an Underlying Fund invests in derivatives tied to fixed income markets, the Fund or Underlying Fund may be more substantially exposed to these risks than a fund that does not invest in derivatives.

Risk [Text Block] rr_RiskTextBlock U.S. Government Agency Obligations Risk: Government agency obligations have different levels of credit support and, therefore, different degrees of credit risk. Some securities issued by agencies and instrumentalities of the U.S. Government are supported by the full faith and credit of the United States, but others are neither insured nor guaranteed by the U.S. Government. The U.S. Department of the Treasury has the authority to provide financial support to these debt obligations, but no assurance can be given that the U.S. Government will do so.

Risk [Text Block] rr_RiskTextBlock Real Estate Risk: The value of real estate-linked derivative instruments and other real estate-related securities such as real estate investment trusts (“REITs”) may be affected by risks similar to those associated with direct ownership of real estate, in addition to the risks of poor performance by a REIT’s manager, changes to tax laws, and failure by the REIT to qualify for favorable treatment. To the extent the Fund invests in REITs, you will indirectly bear fees and expenses of the underlying REITs in addition to the Fund’s direct fees and expenses. REITs may have limited diversification and may not exhibit the same (or any) correlation with inflation that real estate or other real estate securities exhibit.

Risk [Text Block] rr_RiskTextBlock Loan Risk: Loans are subject to risk of loss as a result of borrower default, sensitivity to interest rate and economic changes, valuation difficulties and potential decreased liquidity to a greater extent than other types of investments. The value of any collateral securing a loan may decline, be insufficient to meet the borrower’s obligations, or be difficult or costly to liquidate. It may take longer than 7 days for investments in loans to settle, which may adversely affect an Underlying Fund’s ability to timely honor redemptions.

The risks of owning an ETF generally reflect the risks of owning the underlying securities held by the ETF, although a lack of liquidity in an ETF could result in it being more volatile. In addition, ETF shares may trade at a premium or discount relative to their net asset value. ETFs have management fees and other expenses which the Fund will indirectly bear.

The Fund could also lose money in connection with securities lending transactions if it does not recover the loaned securities and/or the value of the collateral falls, including the value of investments made with cash collateral. Securities lending also may have certain adverse tax consequences. The Fund is not obligated to engage in securities lending, and may discontinue its securities lending activities at any time.

Portfolio Turnover [Text Block] rr_PortfolioTurnoverTextBlock
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.  The Fund does not pay transaction costs when buying and selling shares of other mutual funds, however, the underlying funds pay transaction costs when buying and selling securities for their portfolio. 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 247.29% of the average value of its portfolio.

Strategy [Heading] rr_StrategyHeading Principal Investment Strategies of the Fund
Strategy Narrative [Text Block] rr_StrategyNarrativeTextBlock
The Fund operates as a fund of funds, investing primarily in registered mutual funds (both actively and passively managed) and exchange-traded funds (“ETFs”). The funds in which the Fund may invest are referred to herein as the “Underlying Funds.” AssetMark, Inc. (“AssetMark” or the “Advisor”) believes that investing in Underlying Funds provides the Fund with an efficient means of creating a portfolio that provides investors with indirect exposure to a broad range of fixed income and equity securities. By investing in the Fund, you will indirectly bear fees and expenses of the Underlying Funds in addition to the Fund’s direct fees and expenses. In order to obtain exposure to certain markets, asset classes or active management styles, the Fund may buy Underlying Funds managed by the Advisor or its affiliates, which, in turn, invest in various securities, including ETFs. The Fund may also invest directly in securities and other exchange-traded products, such as exchange-traded notes (“ETNs”).
The Advisor’s asset allocation decisions will be based on different factors and analytical approaches, derived from volatility managed and income focused asset allocation approaches developed by various research providers and considered by the Advisor in constructing the Fund’s portfolio. The research providers’ volatility managed and income focused asset allocation approaches typically utilize fundamental and quantitative analyses of global market and economic conditions and assumptions regarding risks and returns. The Advisor seeks to create a portfolio that is optimized to seek to achieve consistent returns over time regardless of the market environment while also seeking to generate high levels of income.
In pursuing the Fund’s objective, the Fund invests, either directly or indirectly via the Underlying Funds, in various types of domestic and international fixed income securities, domestic and international equity securities (including American Depositary Receipts (“ADRs”) and Global Depositary Receipts (“GDRs”)) and cash equivalent money market securities.
The asset classes in which the Fund may invest, either directly or indirectly via the Underlying Funds, include, but are not limited to, debt securities of governments, government agencies and supranational entities, debt securities of corporations, preferred stock, bank loans, convertible securities, mortgage- or asset-backed securities, inflation-linked securities and other securitized or collateralized debt obligations, higher-yielding bonds (sometimes referred to as “junk bonds”), including emerging market debt, dividend-paying securities of small- and large-capitalization companies, growth and value stocks, equity securities from developed and emerging market countries, and both domestic and international real estate securities. The Fund may also take positions in various global currencies and may hold positions in instruments that are denominated in currencies other than the U.S. dollar. It is possible that a significant portion of the Fund’s assets may be invested, directly or indirectly, in non-investment grade fixed income investments with varying maturities.
The Fund may allocate assets to passive index-oriented ETFs that provide exposure to various fixed income and equity securities and sectors. Using this type of strategy, the Fund seeks to tactically avoid risk by reducing exposure to unattractive sectors at the appropriate times, while also increasing exposure to attractive sectors on a timely basis. The Fund may also invest in inverse, leveraged, and inverse-leveraged ETFs and ETNs. Inverse ETFs and ETNs are designed to correlate inversely with the performance of an index. Leveraged and inverse-leveraged ETFs and ETNs seek investment results that correspond to two or more times the performance of an index or inverse of the performance of an index, respectively.
The Fund may utilize an asset allocation strategy that builds on a foundation of alternative investments, such as long/short equity funds that seek a modest positive return from equity investments, that attempts to stay insulated from general stock market volatility, combined with opportunistic equity and fixed income investments strategically selected to enhance returns. The Fund’s alternative strategies may also include diversified risk premium strategies, including market risk transfer strategies, alternative (marketplace) lending and real estate, reinsurance and commodity-linked derivatives, including, but not limited to, commodity futures contracts and bitcoin futures contracts and options thereon.
The Fund’s asset allocation mix among fixed income, equity and cash equivalent money market securities is intended to change over time. The Fund does not have a set target asset allocation mix. If the Advisor believes that market conditions are unfavorable or overvalued, it may significantly increase the allocation to more defensive asset classes. The Advisor also has broad latitude to allocate assets to equity securities in pursuit of perceived opportunities for additional return. Based on these judgments, the Fund’s asset allocation mix may significantly change over time in response to opportunities as they are identified.
The Fund may invest in Underlying Funds that use derivatives for risk management purposes or engage in significant use of derivatives as part of their investment strategies. An Underlying Fund may use derivatives to earn income and enhance returns, to manage or adjust the risk and duration exposure profile of the Underlying Fund, to replace more traditional direct investments or to obtain exposure to certain markets, interest rates, sectors or individual issuers. The derivatives used by an Underlying Fund may allow the Underlying Fund to obtain net long or net negative (short) exposures to selected interest rates, countries, duration or credit risks. An Underlying Fund may also use derivatives to hedge or gain exposure to currencies.
The Fund lends its portfolio securities to seek to generate additional income.

Additionally, each Fund may invest in other investment companies for which the Advisor or an affiliate serves as investment advisor (i.e., affiliated Underlying Funds). Such investments in the Underlying Funds could create a conflict of interest for the Advisor in managing the Fund’s assets.

Junk bonds are subject to greater credit risk than higher-grade securities, have a greater risk of default and are considered speculative. Issuers of junk bonds are more likely to experience financial difficulties that may impair their ability to make principal and interest payments.
Service Shares Prospectus | GuidePath(R) Flexible Income Allocation Fund | Leveraged And Inverse ETF/ETN Risk Member  
Prospectus [Line Items] rr_ProspectusLineItems  
Risk [Text Block] rr_RiskTextBlock Leveraged and Inverse ETF/ETN Risk: Inverse ETFs/ETNs generally use derivatives and short sales that, in combination, are designed to produce returns that move in the opposite direction of the indices they track. To the extent the Fund invests in ETFs/ETNs that seek to provide investment results that are the inverse of the performance of an underlying index, the Fund will indirectly be subject to the risk that the performance of such ETF/ETN will fall as the performance of that ETF or ETN’s benchmark rises, a result that is the opposite from traditional mutual funds. The Fund’s use of leveraged and inverse-leveraged ETFs and ETNs has the economic effect of creating financial leverage. Financial leverage magnifies exposure to the swings in prices of an asset class and results in increased volatility, which means the Fund will have the potential for greater gains, as well as the potential for greater losses, than if the Fund had not invested in these instruments at all.
Service Shares Prospectus | GuidePath(R) Flexible Income Allocation Fund | Small And Medium Capitalization Company Risk Member  
Prospectus [Line Items] rr_ProspectusLineItems  
Risk [Text Block] rr_RiskTextBlock Small and Medium Capitalization Company Risk: Small and medium capitalization companies often have narrower markets, fewer products or services to offer and more limited managerial and financial resources than do larger, more established companies. As a result, their performance can be more volatile, and they face a greater risk of business failure, which could increase the volatility and risk of loss of the Fund's assets.
Service Shares Prospectus | GuidePath(R) Flexible Income Allocation Fund | Derivatives Risk Member  
Prospectus [Line Items] rr_ProspectusLineItems  
Risk [Text Block] rr_RiskTextBlock Derivatives Risk: A derivative is an instrument with a value based on the performance of an underlying currency, security, index or other reference asset. The use of derivatives involves risks different from, or greater than, the risks associated with investing in more traditional investments. Derivatives involve costs, may create leverage, and may be illiquid, volatile, and difficult to value. The Fund may not be able to close out or sell a derivative position at a particular time or at an anticipated price. The use of derivatives could also result in a loss if the counterparty to the transaction does not perform as promised, including because of such counterparty’s bankruptcy or insolvency. The investment results achieved by the use of derivatives by the Fund may not match or fully offset changes in the value of the underlying currency, security, index or other reference asset that it was attempting to hedge or the investment opportunity the Fund was attempting to pursue. For example, with currency derivatives, there may be an imperfect correlation between a Fund’s portfolio holdings of securities denominated in a particular currency and the currencies underlying the currency derivatives entered into by the Fund.
Service Shares Prospectus | GuidePath(R) Flexible Income Allocation Fund | Debt/Fixed Income Securities Risk Member  
Prospectus [Line Items] rr_ProspectusLineItems  
Risk [Text Block] rr_RiskTextBlock Debt/Fixed Income Securities Risk: An increase in interest rates typically causes a fall in the value of the debt securities in which the Fund may invest. Conversely, very low or negative interest rates may heighten the Fund's susceptibility to interest rate risk and diminish yield and performance.The value of your investment in the Fund may change in response to changes in the credit ratings of the debt securities in the Fund's portfolio. Moreover, rising interest rates or lack of market participants may lead to decreased liquidity in the bond and loan markets, making it more difficult for the Fund to sell its holdings at a time when the Fund's manager might wish to sell. Lower rated securities ("junk bonds") are generally subject to greater risk of loss of your money than higher rated securities. Issuers may (increase) decrease prepayments of principal when interest rates (fall) increase, affecting the maturity of the debt security and causing the value of the security to decline. To the extent the Fund or an Underlying Fund invests in derivatives tied to fixed income markets, the Fund or Underlying Fund may be more substantially exposed to these risks than a fund that does not invest in derivatives.
Service Shares Prospectus | GuidePath(R) Flexible Income Allocation Fund | Bitcoin Investments Risk Member  
Prospectus [Line Items] rr_ProspectusLineItems  
Risk [Text Block] rr_RiskTextBlock Bitcoin Investments Risk: Certain Underlying Funds may invest in bitcoin, bitcoin futures contracts and options on bitcoin futures contracts (or options on ETFs that invest in bitcoin or bitcoin futures contracts). Bitcoin operates without central authority (such as a bank) and is not backed by any government, corporation, or other entity. Bitcoin is not generally accepted as legal tender. Regulation of bitcoin and other cryptocurrencies is still developing. Federal, state and/or foreign governments may restrict the development, use, or exchange of bitcoin. The market price of bitcoin has historically been highly volatile. The price of bitcoin could fall sharply (potentially to zero) for various reasons, including, but not limited to, regulatory changes, issues impacting the bitcoin network, events involving entities that facilitate transactions in bitcoin, or changes in user preferences in favor of alternative cryptocurrencies. Furthermore, events that impact other cryptocurrencies may lead to a decline in the value of bitcoin. Cryptocurrency exchanges and other trading venues on which cryptocurrencies trade are relatively new and, in most cases, largely unregulated. Accordingly, cryptocurrency exchanges may be more exposed to fraud and failure than established, regulated exchanges for securities, derivatives and other currencies. Cryptocurrency exchanges are also subject to cyber security risks. Cryptocurrency exchanges have experienced cyber security breaches in the past and may be breached in the future, which could result in the theft and/or loss of bitcoin and impact the value of bitcoin futures. Furthermore, cyber security events, legal or regulatory actions, fraud, and technical glitches, may cause a cryptocurrency exchange to shut down temporarily or permanently, which may also affect the value of bitcoin and/or bitcoin futures.
Shares of ETFs that hold bitcoin and/or bitcoin futures may trade in the secondary market at a premium to or discount from their NAVs, and an Underlying Fund may purchase or sell shares of bitcoin futures ETFs at prices above or below such NAVs. Because the market price of ETF shares depends in part on the demand in the market for the shares, as well as on the value of the ETF’s component assets, and because the market price of ETF shares is subject to tracking error, the market price of a bitcoin futures ETF may be more volatile than the underlying bitcoin futures contracts in which the bitcoin futures ETF invests. In addition, an Underlying Fund may not be able to liquidate bitcoin futures ETF holdings at the time or price desired, which may adversely impact the Underlying Fund’s performance and in turn, the value of the Fund’s investment. Furthermore, there may be times when the exchange halts trading in the shares of a bitcoin futures ETF, in which case the Underlying Fund would be unable to sell them until trading is resumed.

Prospectus [Line Items] rr_ProspectusLineItems  
Risk [Text Block] rr_RiskTextBlock Bitcoin Market Volatility Risk: Bitcoin has historically exhibited higher price volatility than more traditional asset classes. For instance, the two largest historical drawdowns were during the period from June 8, 2011 to November 18, 2011 and the period from December 17, 2017 to December 14, 2018, when bitcoin experienced a decline of roughly 93% and 84%, respectively. The price of bitcoin and therefore the value of an investment in the Underlying Fund may be negatively impacted by unfavorable investor sentiment resulting from recent developments in the broader digital asset industry, including the fallout from the recent insolvency proceedings of digital asset market participants such as digital asset exchange FTX Trading Ltd., et al. (and its affiliated hedge fund Alameda Research LLC), digital asset hedge fund Three Arrows Capital and digital asset lenders Celsius Network LLC, et al., Voyager Digital Ltd., et al. and BlockFi Inc. The value of bitcoin and, therefore, of an Underlying Fund’s bitcoin strategy, could decline rapidly, including to zero, which would adversely affect the Underlying Fund’s NAV per share.

Prospectus [Line Items] rr_ProspectusLineItems  
Risk [Text Block] rr_RiskTextBlock Insurance-Linked Securities Risk: The principal risk of investments in insurance-linked securities is that a triggering event (which could include a natural disaster like an earthquake or tornado or a commercial or industrial accident like an aviation disaster or oil spill) occurs, resulting an Underlying Fund losing all or a significant portion of the principal it has invested in the security and the right to additional interest payments with respect to the security. If multiple triggering events occur that impact a significant portion of the portfolio of the Underlying Fund, the Underlying Fund could suffer substantial losses and an investor will lose money. Event-linked or catastrophe bonds carry large uncertainties and major risk exposures to adverse conditions. Certain reinsurance investments may be difficult to value. There is no way to accurately predict whether a triggering event will occur and, because of this significant uncertainty, insurance-linked securities carry a high degree of risk.

Prospectus [Line Items] rr_ProspectusLineItems  
Risk [Text Block] rr_RiskTextBlock Marketplace Loan Risk: Investments by Underlying Funds in loans sourced through marketplace lending platforms are subject to additional risks than those applicable to investments in loans generally. If a borrower is unable or fails to make payments on a loan for any reason, an Underlying Fund may not have direct recourse against the borrower or may be otherwise limited in its ability to directly enforce its rights under the loan, whether through the borrower or the marketplace lending platform through which the loan was originated. Borrowings obtained through marketplace lending platforms may not limit borrowers from incurring additional debt which may impair the borrower’s ability to repay interest and principal of the original loan. Default history for alternative lending platforms is limited. Future defaults may be higher than historical defaults and the timing of defaults may vary significantly from historical observations. An Underlying Fund may have limited knowledge about the underlying loans to which it has exposure and is dependent upon the platform for information regarding the loans and borrowers’ credit information. Such information may be incomplete, inaccurate or outdated and may, therefore, not accurately reflect the borrowers’ actual creditworthiness. Disruptions in the business of a platform may also negatively impact the value of loans sourced through that platform. Investments in loans sourced through a marketplace lending platform may also be negatively impacted if the platform or a third-party service provider becomes unable or unwilling to fulfill its obligations in servicing the loans.

In the event a borrower defaults on a subordinated loan and lacks sufficient assets to satisfy such loan, the Underlying Fund may suffer a loss of principal or interest. In the event a borrower declares bankruptcy, the Underlying Fund may not have full recourse to the assets of the borrower, or the assets of the borrower may not be sufficient to satisfy the loan. If a borrower defaults on a loan owned by the Underlying Fund or on debt senior to such loan, or in the event of a borrower bankruptcy, such loan will be satisfied only after the senior debt is paid in full. These types of investments may become unsecured as a result of foreclosure by the senior lender.

To the extent the Fund invests in REITs, you will indirectly bear fees and expenses of the underlying REITs in addition to the Fund’s direct fees and expenses.

Risk [Text Block] rr_RiskTextBlock Portfolio Turnover Risk: Depending on market and other conditions, the Fund may experience a high portfolio turnover, which may result in higher brokerage costs and transaction costs (which could reduce investment returns). Distributions of net short-term capital gains are taxable as ordinary income when Fund shares are held in a taxable account. A fund with a high portfolio turnover rate (a measure of how frequently assets within a fund are bought and sold) is more likely to generate short-term capital gains than a fund with a low portfolio turnover rate.

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.  The Fund does not pay transaction costs when buying and selling shares of other mutual funds, however, the underlying funds pay transaction costs when buying and selling securities for their portfolio. 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 0% of the average value of its portfolio. The portfolio turnover rate does not include purchases and sales of securities or other instruments whose maturities or expiration dates at the time of purchase were one year or less. If these were included, the Fund’s portfolio turnover rate would be higher.

Strategy [Heading] rr_StrategyHeading Principal Investment Strategies of the Fund
Strategy Narrative [Text Block] rr_StrategyNarrativeTextBlock
Under normal market conditions, the Fund seeks exposure to various asset classes, which may vary significantly over time but is generally expected to include exposure to equity markets, bond markets, interest rates, commodities, and currencies. The sub-advisor uses proprietary quantitative models to identify price trends in equity, fixed income, currency and commodity instruments across time periods of various lengths. The sub-advisor believes that asset prices may show persistent trading behavior due to a number of behavioral biases among market participants as well as certain risk-management policies that will identify assets to purchase in upward-trending markets and identify assets to sell in downward-trending markets.
Although the Fund seeks exposure across a variety of asset classes, it may emphasize one or two of the asset classes or a limited number of exposures within an asset class. There are no geographic limits on the asset class exposures and there is great flexibility in looking for investments around the globe, including in emerging markets. The Fund may have both “short” and “long”’ exposures within an asset class based upon potential opportunities. A “short” exposure will benefit when the underlying asset class decreases in price. A “long” exposure will benefit when the underlying asset class increases in price.
The Fund expects to pursue its investment strategies by making extensive use of a variety of derivative instruments, including futures contracts, forward currency contracts and swaps. A futures contract is a standard binding agreement to buy or sell a specified quantity of an underlying reference asset, such as a specific security, currency or commodity, at a specified price at a specified later date. A forward currency contract involves an obligation to purchase or sell a specific non-U.S. currency in exchange for another currency, which may be U.S. dollars, at a future date, which may be any fixed number of days from the date of the contract agreed upon by the parties, at a price set at
the time of the contract. Generally, swap agreements are contracts between the Fund and another party (the swap counterparty) involving the exchange of payments on specified terms over periods ranging from a few days to multiple years.
The Fund may also invest in exchange-traded funds (“ETFs”) or exchange-traded notes (“ETNs”) through which the Fund can participate in the performance of one or more asset classes.
In connection with the Fund’s managed futures strategy, the Fund’s portfolio may be concentrated in the financial services industry, which means the Fund may invest more than 25% of its total assets in securities and other obligations (for example, bank certificates of deposit, repurchase agreements and time deposits) of issuers in such industry. A significant portion of the assets of the Fund may be invested directly or indirectly in money market instruments, which may include, but are not limited to, U.S. Government securities, U.S. government agency securities, short-term fixed income securities, overnight and/or fixed term repurchase agreements, money market mutual fund shares, and cash and cash equivalents with one year or less term to maturity. These cash or cash equivalent holdings serve as collateral for certain of the Fund’s derivatives positions.
As a result of the Fund’s use of derivatives, the Fund may have highly leveraged exposure to one or more asset classes at times. The Investment Company Act of 1940, as amended (the “1940 Act”) and the rules and interpretations thereunder impose certain limitations on the Fund’s ability to use leverage; however, the Fund is not subject to any additional limitations on its net long and short exposures. For example, the Fund, on average, could hold instruments that provide three to four times the net return (positive or negative) of an unleveraged investment in the equities, bonds, interest rates, commodities, or currencies underlying such instruments. When taking into account derivative instruments and instruments with a maturity of one year or less at the time of acquisition, the Fund’s strategy will result in frequent portfolio trading and high portfolio turnover (typically greater than 300% per year). The Advisor expects the Fund’s net asset value over short term periods to be volatile because of the significant use of instruments that have a leveraging effect. Volatility is a statistical measurement of the dispersion of returns of a security or fund or index, as measured by the annualized standard deviation of its returns. Higher volatility generally indicates higher risk. The Fund lends its portfolio securities to seek to generate additional income.
Although the Fund does not intend to invest in physical commodities directly, the Fund expects to obtain investment exposure to commodities and commodity related derivatives by investing in a wholly-owned subsidiary organized under the laws of the Cayman Islands that will make commodity-related investments (the “Subsidiary”). Through the Subsidiary, the Fund may invest in “commodity-linked” or “commodity index-linked” investments such as commodity futures contracts and commodity swap agreements.

Certain alternative strategies involve the risk that a counterparty to a transaction will not perform as promised, which could result in losses to the Fund. Furthermore, alternative strategies may employ leverage, involve extensive short positions and/or focus on narrow segments of the market, which may magnify the overall risks and volatility associated with such investments.

Examples of risks affecting the financial services industry include changes in governmental regulation, issues relating to the availability and cost of capital, changes in interest rates and/or monetary policy and price competition. In addition, financial services companies are often more highly leveraged than other companies, making them inherently riskier.

Service Shares Prospectus | GuidePath(R) Managed Futures Strategy Fund | Derivatives Risk Member  
Prospectus [Line Items] rr_ProspectusLineItems  
Risk [Text Block] rr_RiskTextBlock Derivatives Risk: A derivative is an instrument with a value based on the performance of an underlying currency, security, index or other reference asset. The use of derivatives involves risks different from, or greater than, the risks associated with investing in more traditional investments. Derivatives involve costs, may create leverage, and may be illiquid, volatile, and difficult to value. The Fund may not be able to close out or sell a derivative position at a particular time or at an anticipated price. The use of derivatives could also result in a loss if the counterparty to the transaction does not perform as promised, including because of such counterparty’s bankruptcy or insolvency. The investment results achieved by the use of derivatives by the Fund may not match or fully offset changes in the value of the underlying currency, security, index or other reference asset that it was attempting to hedge or the investment opportunity the Fund was attempting to pursue.
Service Shares Prospectus | GuidePath(R) Managed Futures Strategy Fund | Leverage Risk Member  
Prospectus [Line Items] rr_ProspectusLineItems  
Risk [Text Block] rr_RiskTextBlock Leverage Risk: The Fund’s use of derivatives such as futures contracts, forward contracts and swaps has the economic effect of creating financial leverage. Financial leverage magnifies exposure to the swings in prices of an asset class underlying a derivatives instrument and results in increased volatility, which means the Fund will have the potential for greater gains, as well as the potential for greater losses, than if the Fund had not invested in derivatives at all.
Service Shares Prospectus | GuidePath(R) Managed Futures Strategy Fund | Debt/Fixed Income Securities Risk Member  
Prospectus [Line Items] rr_ProspectusLineItems  
Risk [Text Block] rr_RiskTextBlock Debt/Fixed Income Securities Risk: An increase in interest rates typically causes a fall in the value of the debt securities in which the Fund may invest. Conversely, very low or negative interest rates may heighten the Fund's susceptibility to interest rate risk and diminish yield and performance.The value of your investment in the Fund may change in response to changes in the credit ratings of the debt securities in the Fund's portfolio. Moreover, rising interest rates or lack of market participants may lead to decreased liquidity in the bond and loan markets, making it more difficult for the Fund to sell its holdings at a time when the Fund's manager might wish to sell. Lower rated securities ("junk bonds") are generally subject to greater risk of loss of your money than higher rated securities. Issuers may (increase) decrease prepayments of principal when interest rates (fall) increase, affecting the maturity of the debt security and causing the value of the security to decline. To the extent the Fund or an Underlying Fund invests in derivatives tied to fixed income markets, the Fund or Underlying Fund may be more substantially exposed to these risks than a fund that does not invest in derivatives.

Risk [Text Block] rr_RiskTextBlock U.S. Government Agency Obligations Risk: Government agency obligations have different levels of credit support and, therefore, different degrees of credit risk. Some securities issued by agencies and instrumentalities of the U.S. Government are supported by the full faith and credit of the United States, but others are neither insured nor guaranteed by the U.S. Government. The U.S. Department of the Treasury has the authority to provide financial support to these debt obligations, but no assurance can be given that the U.S. Government will do so.

Risk [Text Block] rr_RiskTextBlock Commodities Risk: The Fund’s investment in commodity-linked investments and other commodity/natural resource-related securities may subject the Fund to greater volatility than investments in traditional securities. Commodity-linked investments may have a substantial risk of loss with respect to both principal and interest, and their returns may deviate significantly from the return of the underlying commodity, instruments, or measures. The ability of the Fund to invest in commodity-linked investments without exposing the Fund to Fund-level tax is limited under the Internal Revenue Code of 1986, as amended.

Service Shares Prospectus | GuidePath(R) Managed Futures Strategy Fund | Variable Rate Securities Risk Member  
Prospectus [Line Items] rr_ProspectusLineItems  
Risk [Text Block] rr_RiskTextBlock Variable Rate Securities Risk: Changes in interest rates on variable rate securities may lag behind changes in market rates, causing the value of such securities to decline during periods of rising interest rates until their interest rates reset to market rates. During periods of declining interest rates, interest rates on variable rate securities generally reset downward, and their market value is unlikely to rise to the same extent as the value of comparable fixed rate securities. Newly originated variable rate securities (including reissuances and restructured loans) may possess lower levels of credit document protections than has historically been the case. Accordingly, in the event of default the Fund may experience lower levels of recoveries than has historically been the norm.

The Fund could also lose money in connection with securities lending transactions if it does not recover the loaned securities and/or the value of the collateral falls, including the value of investments made with cash collateral.

By investing in the Fund, you indirectly bear the expenses of the Subsidiary. Gains or losses from trading in commodity-linked derivatives, such as those held by the Subsidiary, may be taxed, in part, as long term capital gains or losses and, in part, as short term capital gains or losses.

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.  The Fund does not pay transaction costs when buying and selling shares of other mutual funds, however, the underlying funds pay transaction costs when buying and selling securities for their portfolio. 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 258.88% of the average value of its portfolio.

Strategy [Heading] rr_StrategyHeading Principal Investment Strategies of the Fund
Strategy Narrative [Text Block] rr_StrategyNarrativeTextBlock
The Fund invests primarily in a portfolio of actively and passively managed registered mutual funds and exchange-traded funds (“ETFs”), in addition to direct investments. The funds in which the Fund may invest are referred to herein as the “Underlying Funds.” AssetMark, Inc. (“AssetMark” or the “Advisor”) believes that investing in Underlying Funds provides the Fund with an efficient means of creating a portfolio that provides investors with indirect exposure to a broad range of investments. By investing in the Fund, you will indirectly bear fees and expenses of the Underlying Funds in addition to the Fund’s direct fees and expenses. In order to obtain exposure to certain markets, asset classes or active management styles, the Fund may buy Underlying Funds managed by the Advisor or its affiliates, which, in turn, invest in
various securities, including ETFs. The Fund may also invest directly in securities and other exchange-traded products, such as exchange-traded notes (“ETNs”).
Under normal circumstances, the Fund will make investments in fixed income securities, including cash equivalents, that primarily have a maturity that is between 0 and 5 years. The asset classes in which the Fund may invest, either directly or indirectly via the Underlying Funds, include, but are not limited to, debt securities of governments, government agencies and supranational entities, debt securities of corporations, preferred stock, bank loans, convertible securities, mortgage- or asset-backed securities, inflation-linked securities and other securitized or collateralized debt obligations and higher-yielding bonds (sometimes referred to as “junk bonds”), including emerging market debt. The Fund may also take positions in various global currencies and may hold positions in instruments that are denominated in currencies other than the U.S. dollar. In pursuit of the Fund’s secondary investment objective of capital preservation, the Fund expects under normal circumstances to invest a significant portion of its assets in cash and cash equivalents, including by investing approximately 25% to 50% of the Fund’s total assets in money market funds.
In selecting debt securities for the Fund, the Advisor develops an outlook for credit markets, interest rates, currency exchange rates and the economy, analyzes individual credit and prepayment risks, and uses other security selection techniques. The proportion of the Fund’s assets committed to investment in securities with particular characteristics (such as quality, sector, interest rate or maturity) varies based on the Advisor’s outlook for the U.S. economy and the economies of other countries in the world, the financial markets and other factors.
The Fund may shift its investments from one asset class to another based on the Advisor’s analysis of the best opportunities for the Fund’s portfolio in a given market.  The Fund may invest up to 20% of its total assets in bonds rated below investment grade.  The Fund may invest up to 20% of its total assets in securities denominated in foreign currencies and may invest without limit in U.S. dollar-denominated securities of foreign issuers.
The Fund’s asset allocation mix may change periodically over time. The Fund does not have a set target asset allocation mix. If the Advisor believes that market conditions are unfavorable or overvalued, it may significantly increase the allocation to more defensive asset classes. Based on these judgments, the Fund’s asset allocation mix may significantly change over time in response to opportunities as they are identified. In certain circumstances the Fund may be fully invested in cash equivalents securities for an extended period of time.
The Fund may invest in Underlying Funds that use derivatives for risk management purposes or as part of their investment strategies. An Underlying Fund may use derivatives to earn income and enhance returns, to manage or adjust the risk and duration exposure profile of the Underlying Fund, to replace more traditional direct investments or to obtain exposure to certain markets, interest rates, sectors or individual issuers. The derivatives used by an Underlying Fund may allow the Underlying Fund to obtain net long or net negative (short) exposures to selected interest rates, countries, duration or credit risks. An Underlying Fund may also use derivatives to hedge or gain exposure to currencies.
The Fund lends its portfolio securities to seek to generate additional income.

Additionally, the Fund may invest in other investment companies for which the Advisor or an affiliate serves as investment advisor (i.e., affiliated Underlying Funds). Such investments in the Underlying Funds could create a conflict of interest for the Advisor in managing the Fund’s assets.

Risk [Text Block] rr_RiskTextBlock Money Market Funds Risk. Although money market funds generally seek to preserve the value of an investment at $1.00 per share, the Fund may lose money by investing in money market funds. A money market fund’s sponsor has no legal obligation to provide financial support to the money market fund. The credit quality of a money market fund’s holdings can change rapidly in certain markets, and the default of a single holding could have an adverse impact on the money market fund's share price. A money market fund’s share price can also be negatively affected during periods of high redemption pressures, illiquid markets and/or significant market volatility.

For example, when interest rates rise, the market value of fixed income securities declines. If the market value of the Fund’s investments decreases, investors in the Fund may lose money. The Fund may face a heightened level of interest rate risk due to changes in general economic conditions, inflation and monetary policy, including interest rate changes by the Federal Reserve.

Risk [Text Block] rr_RiskTextBlock Mortgage- and Asset-Backed Securities Risk: Payments on mortgage- and asset-backed securities depend upon assets held by the issuer and collections on the underlying mortgages or loans. Issuers of asset-backed securities may have limited ability to enforce the security interest in the underlying assets, and credit enhancements provided to support the securities, if any, may be inadequate to protect investors in the event of default. Mortgage- and asset-backed securities are also subject to prepayment risk, which is the risk that the borrower will prepay some or all of the principal owed to the issuer. If that happens, a Fund may have to replace the security by investing the proceeds in a less attractive security. In certain market conditions, asset-backed securities may experience volatile fluctuations in value and periods of illiquidity.

Certain alternative strategies involve the risk that a counterparty to a transaction will not perform as promised, which could result in losses to the Fund. Furthermore, alternative strategies may employ leverage, involve extensive short positions and/or focus on narrow segments of the market, which may magnify the overall risks and volatility associated with such investments.

Issuers of junk bonds are more likely to experience financial difficulties that may impair their ability to make principal and interest payments.
Service Shares Prospectus | GuidePath(R) Conservative Income Fund | Derivatives Risk Member  
Prospectus [Line Items] rr_ProspectusLineItems  
Risk [Text Block] rr_RiskTextBlock Derivatives Risk: A derivative is an instrument with a value based on the performance of an underlying currency, security, index or other reference asset. The use of derivatives involves risks different from, or greater than, the risks associated with investing in more traditional investments. Derivatives involve costs, may create leverage, and may be illiquid, volatile, and difficult to value. The Fund may not be able to close out or sell a derivative position at a particular time or at an anticipated price. The use of derivatives could also result in a loss if the counterparty to the transaction does not perform as promised, including because of such counterparty’s bankruptcy or insolvency. The investment results achieved by the use of derivatives by the Fund may not match or fully offset changes in the value of the underlying currency, security, index or other reference asset that it was attempting to hedge or the investment opportunity the Fund was attempting to pursue.
Service Shares Prospectus | GuidePath(R) Conservative Income Fund | Debt/Fixed Income Securities Risk Member  
Prospectus [Line Items] rr_ProspectusLineItems  
Risk [Text Block] rr_RiskTextBlock Debt/Fixed Income Securities Risk: An increase in interest rates typically causes a fall in the value of the debt securities in which the Fund may invest. Conversely, very low or negative interest rates may heighten the Fund's susceptibility to interest rate risk and diminish yield and performance.The value of your investment in the Fund may change in response to changes in the credit ratings of the debt securities in the Fund's portfolio. Moreover, rising interest rates or lack of market participants may lead to decreased liquidity in the bond and loan markets, making it more difficult for the Fund to sell its holdings at a time when the Fund's manager might wish to sell. Lower rated securities ("junk bonds") are generally subject to greater risk of loss of your money than higher rated securities. Issuers may (increase) decrease prepayments of principal when interest rates (fall) increase, affecting the maturity of the debt security and causing the value of the security to decline. To the extent the Fund or an Underlying Fund invests in derivatives tied to fixed income markets, the Fund or Underlying Fund may be more substantially exposed to these risks than a fund that does not invest in derivatives.

Prospectus [Line Items] rr_ProspectusLineItems  
Risk [Text Block] rr_RiskTextBlock U.S. Government Agency Obligations Risk: Government agency obligations have different levels of credit support and, therefore, different degrees of credit risk. Some securities issued by agencies and instrumentalities of the U.S. Government are supported by the full faith and credit of the United States, but others are neither insured nor guaranteed by the U.S. Government. For example, Connecticut Avenue Securities issued by the Federal National Mortgage Association and Structured Agency Credit Risk debt notes issued by the Federal Home Loan Mortgage Association carry no guarantee whatsoever and the risk of default associated with these securities would be borne by the Fund. The U.S. Department of the Treasury has the authority to provide financial support to these debt obligations, but no assurance can be given that the U.S. Government will do so.

Risk [Text Block] rr_RiskTextBlock Convertible Securities Risk: The value of convertible securities may fall when interest rates rise and increase when interest rates fall. The prices of convertible securities with longer maturities tend to be more volatile than those with shorter maturities. Value also tends to change whenever the market value of the underlying common or preferred stock fluctuates.

Risk [Text Block] rr_RiskTextBlock Loan Risk: Loans are subject to risk of loss as a result of borrower default, sensitivity to interest rate and economic changes, valuation difficulties and potential decreased liquidity to a greater extent than other types of investments. The value of any collateral securing a loan may decline, be insufficient to meet the borrower’s obligations, or be difficult or costly to liquidate. It may take longer than 7 days for investments in loans to settle, which may adversely affect an Underlying Fund’s ability to timely honor redemptions.

Risk [Text Block] rr_RiskTextBlock Portfolio Turnover Risk: Depending on market and other conditions, the Fund may experience a high portfolio turnover, which may result in higher brokerage costs and transaction costs (which could reduce investment returns). Distributions of net short-term capital gains are taxable as ordinary income when Fund shares are held in a taxable account. A fund with a high portfolio turnover rate (a measure of how frequently assets within a fund are bought and sold) is more likely to generate short-term capital gains than a fund with a low portfolio turnover rate.

Risk [Text Block] rr_RiskTextBlock Preferred Stock Risk: A preferred stock may decline in price, or fail to pay dividends when expected, because the issuer experiences a decline in its financial status. Preferred stocks often behave like debt securities, but have a lower payment priority than the issuer’s bonds or other debt securities. Therefore, they may be subject to greater credit risk than those of debt securities. Preferred stocks also may be significantly less liquid than many other securities, such as corporate debt or common stock.
Service Shares Prospectus | GuidePath(R) Conservative Income Fund | Extension Risk Member

Risk [Text Block] rr_RiskTextBlock Extension Risk: As interest rates rise, repayments of principal on certain debt securities, including, but not limited to, floating rate loans and mortgage-related securities, may occur at a slower rate than expected and the expected maturity of those securities could lengthen as a result. Securities that are subject to extension risk generally have a greater potential for loss when prevailing interest rates rise, which could cause their values to fall sharply. Interest-only and principal-only securities are especially sensitive to interest rate changes, which can affect not only their prices but can also change the income flows and repayment assumptions about those investments.

Risk [Text Block] rr_RiskTextBlock Securities Lending Risk: When the Fund lends its portfolio securities, the Fund is subject to the risk that the borrower may fail to return the securities in a timely manner or at all, resulting in a loss to the Fund and/or a delay in recovering the loaned securities. The Fund could also lose money in connection with securities lending transactions if it does not recover the loaned securities and/or the value of the collateral falls, including the value of investments made with cash collateral. Securities lending also may have certain adverse tax consequences. The Fund is not obligated to engage in securities lending, and may discontinue its securities lending activities at any time.

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.  The Fund does not pay transaction costs when buying and selling shares of other mutual funds, however, the underlying funds pay transaction costs when buying and selling securities for their portfolio. 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 288.92% of the average value of its portfolio.

Strategy [Heading] rr_StrategyHeading Principal Investment Strategies of the Fund
Strategy Narrative [Text Block] rr_StrategyNarrativeTextBlock
The Fund invests primarily in a portfolio of actively and passively managed registered mutual funds, exchange-traded funds (“ETFs”) and closed-end funds, in addition to direct investments in securities and certain derivatives. The funds in which the Fund may invest are referred to herein as the “Underlying Funds.” AssetMark, Inc. (“AssetMark” or the “Advisor”) believes that investing in Underlying Funds provides the Fund with an efficient means of creating a portfolio that provides investors with indirect exposure to a broad range of investments. By investing in the Fund, you will indirectly bear fees and expenses of the Underlying Funds in addition to the Fund’s direct fees and expenses. In order to obtain exposure to certain markets, asset classes or active management styles, the Fund may buy Underlying Funds managed by the Advisor or its affiliates, which, in turn, invest in various securities, including ETFs. The Fund may also invest directly in securities and other exchange-traded products, such as exchange-traded notes (“ETNs”).
The Advisor’s asset allocation decisions will be based on different factors and analytical approaches, derived from volatility-managed and income-focused asset allocation approaches. These approaches typically utilize fundamental and quantitative analyses of global market and economic conditions and assumptions regarding risks and returns. The Advisor seeks to create a portfolio that is optimized to seek high total return and income, managed to contain the potential magnitude of drawdowns in high volatility markets. The Fund may invest up to 20% of its total assets in securities denominated in foreign currencies and may invest without limit in U.S. dollar-denominated securities of foreign issuers.
In pursuing the Fund’s objective, the Fund invests, either directly or indirectly via the Underlying Funds, in various types of domestic and international fixed income securities, domestic and international equity securities (including American Depositary Receipts (“ADRs”) and Global Depositary Receipts (“GDRs”)) and cash equivalent money market securities. The Fund invests in fixed income securities that primarily have a maturity that is between 1 and 10 years and are rated BBB- or higher, or are unrated and deemed to be of comparable quality by the Advisor; provided, however, that the Fund may invest up to 50% of its total assets in bonds rated below investment grade.  Under normal circumstances, the Fund’s portfolio will have an average duration of 2 to 5 years. In some instances, the Fund’s average duration may exceed this range but is not expected to exceed that of the Bloomberg US Aggregate Bond Index.  Duration is a measurement of price sensitivity to interest rate changes.
The asset classes in which the Fund may invest, either directly or indirectly via the Underlying Funds, include, but are not limited to, debt securities of governments, government agencies and supranational entities, debt securities of corporations, bank loans, convertible securities, mortgage- or asset-backed securities, inflation-linked securities and other securitized or collateralized debt obligations, higher-yielding bonds (sometimes referred to as “junk bonds”), including emerging market debt, preferred stock, dividend-paying securities of small- and large-capitalization companies, business development companies (“BDCs”), publicly traded real estate investment trusts (“REITs”), non-traded unregistered REITs, ETFs, and pooled investment funds including private investment funds that are not registered under the 1940 Act (“private funds”) that provide exposure to pools of whole loans, including those sourced through peer-to-peer or marketplace lending platforms. The Fund may also take positions in various global currencies and may hold positions in instruments that are denominated in currencies other than the U.S. dollar. Under normal circumstances, the Fund will make investments in fixed income securities that primarily have a maturity that is between 1 and 10 years.
In selecting debt securities for the Fund, the Advisor develops an outlook for credit markets, interest rates, currency exchange rates and the economy, analyzes individual credit and prepayment risks, and uses other security selection techniques. The proportion of the Fund’s assets committed to investment in securities with particular characteristics (such as quality, sector, interest rate or maturity) varies based on the Advisor’s outlook for the U.S. economy and the economies of other countries in the world, the financial markets and other factors.
The Fund may allocate assets to ETFs that provide exposure to various fixed income and equity securities and sectors. Using this type of strategy, the Fund seeks to tactically avoid risk by reducing exposure to unattractive sectors at the appropriate times, while also increasing exposure to attractive sectors on a timely basis. The ETFs in which the Fund may invest include those that invest primarily in senior bank loans (also referred to as leveraged loans). The Fund may also invest in inverse, leveraged, and inverse-leveraged ETFs and ETNs. Inverse ETFs and ETNs are designed to correlate inversely with the performance of an index. Leveraged and inverse-leveraged ETFs and ETNs seek investment results that correspond to two or more times the performance of an index or inverse of the performance of an index, respectively.
The Fund may engage in a strategy of purchasing and selling (writing) call and put options on indexes or ETFs (hereafter referred to as "call options" and "put options"). The writer of a call option receives cash (the “premium”) from the purchaser. In return, the purchaser of a call option has the right to any appreciation in the value of the underlying index or ETF over a fixed price (the “exercise price”) on a certain date in the future (the “expiration date”). If the purchaser does not exercise the option, the writer of the option retains the premium. If the purchaser exercises the option, the writer of the option pays the purchaser the difference between the value of the underlying index or ETF and the exercise price of the option.
The value of a call option generally increases as the prices of the stocks constituting the underlying index or ETF increase, and decreases as those stocks decrease in price. Conversely, the value of a put option generally increases as the prices of the stocks constituting the underlying index or ETF decrease, and decreases as those stocks increase in price. The premium, the exercise price and the value of the underlying index or ETF will determine the gain or loss realized by the Fund on a written or purchased option. When the Fund has written an option, it generally can repurchase the option prior to the expiration date, ending its obligation. In such case, the difference between the cost of repurchasing the option and the premium received will determine the gain or loss realized by the Fund. While writing call options may reduce the Fund’s volatility and provide a source of steady cash flow, it may also reduce the Fund’s ability to profit from increases in the value of the underlying index or ETF.
Using the proceeds from its written call options, the Fund may buy put options in an attempt to hedge against a significant market decline in the underlying index or ETF that may occur over a short period of time. In addition, the Fund may write call options or put options on the underlying indexes of the ETFs in which the Fund is invested.
The Fund may invest in Underlying Funds that use derivatives for risk management purposes or as part of their investment strategies. An Underlying Fund may use derivatives to earn income and enhance returns, to manage or adjust the risk and duration exposure profile of the Underlying Fund, to replace more traditional direct investments or to obtain exposure to certain markets, interest rates, sectors or individual issuers. The derivatives used by an Underlying Fund may allow the Underlying Fund to obtain net long or net negative (short) exposures to selected interest rates, countries, duration or credit risks. An Underlying Fund may also use derivatives to hedge or gain exposure to currencies. The Fund may also invest directly in futures contracts. It is anticipated that the Fund may have net economic leverage of up to
30% of the Fund’s total assets through its investments in closed-end funds, leveraged ETFs and ETNs, and certain derivatives, such as options and futures contracts.
The Fund’s asset allocation mix among equity, fixed income and cash equivalent money market securities is intended to change frequently over time.  The Fund does not have a set target asset allocation mix among equities, fixed income securities and cash equivalent investments.  If the Advisor believes that the stock market conditions are unfavorable or overvalued, it may significantly increase the allocation to more defensive asset classes such as fixed income or cash equivalent securities.  The Advisor also has broad latitude to allocate assets to equity securities in pursuit of perceived opportunities for additional return.  Based on these judgments, the Fund’s asset allocation mix may significantly change over time in response to opportunities as they are identified. In certain circumstances the Fund may be fully invested in cash equivalent securities for an extended period of time.
The Fund lends its portfolio securities to seek to generate additional income.

Additionally, each Fund may invest in other investment companies for which the Advisor or an affiliate serves as investment advisor (i.e., affiliated Underlying Funds).

Issuers of asset-backed securities may have limited ability to enforce the security
interest in the underlying assets, and credit enhancements provided to support the securities, if any, may be inadequate to protect investors in the event of default. Mortgage- and asset-backed securities are also subject to prepayment risk, which is the risk that the borrower will prepay some or all of the principal owed to the issuer. If that happens, a Fund may have to replace the security by investing the proceeds in a less attractive security. In certain market conditions, asset-backed securities may experience volatile fluctuations in value and periods of illiquidity.

The shares of closed-end funds frequently trade at a premium or discount relative to their net asset value, and many closed-end funds use leverage, or borrowed money, to try to increase returns. In addition, distributions by a closed-end fund may include a return of capital, which would reduce the fund’s net asset value and its earnings capacity. Finally, closed-end funds are allowed to invest in a greater amount of illiquid investments than open-end mutual funds.

Risk [Text Block] rr_RiskTextBlock Business Development Company Risk: BDCs are closed-end investment companies that have elected to register as BDCs. Shareholders bear both their proportionate share of the Fund’s expenses and similar expenses of the BDC when the fund invests in shares of the BDC. BDCs primarily invest in privately-held and small- to medium- capitalization public companies, and are generally considered to be non-rated or below investment grade. The fair values of these investments often are not readily determinable. This could cause the Fund’s investments in a BDC to be inaccurately valued, including overvalued. BDC revenues, income (or losses) and valuations can, and often do, fluctuate suddenly and dramatically, and they face considerable risk of loss. In addition, BDCs often borrow funds to make investments and, as a result, are exposed to the risks of leverage. Leverage magnifies the potential loss on amounts invested and therefore increases the risks associated with an investment in a BDC’s securities.

Risk [Text Block] rr_RiskTextBlock High-Yield Debt Securities Risk: High-yield debt securities or “junk bonds” are debt securities rated below investment grade by a nationally recognized statistical rating organizations (“NRSRO”). Junk bonds are subject to greater credit risk than higher-grade securities, have a greater risk of default and are considered speculative. Issuers of junk bonds are more likely to experience financial difficulties that may impair their ability to make principal and interest payments.
Service Shares Prospectus | GuidePath(R) Income Fund | Leveraged And Inverse ETF/ETN Risk Member  
Prospectus [Line Items] rr_ProspectusLineItems  
Risk [Text Block] rr_RiskTextBlock Leveraged and Inverse ETF/ETN Risk: Inverse ETFs/ETNs generally use derivatives and short sales that, in combination, are designed to produce returns that move in the opposite direction of the indices they track. To the extent the Fund invests in ETFs/ETNs that seek to provide investment results that are the inverse of the performance of an underlying index, the Fund will indirectly be subject to the risk that the performance of such ETF/ETN will fall as the performance of that ETF or ETN’s benchmark rises, a result that is the opposite from traditional mutual funds. The Fund’s use of leveraged and inverse-leveraged ETFs and ETNs has the economic effect of creating financial leverage. Financial leverage magnifies exposure to the swings in prices of an asset class and results in increased volatility, which means the Fund will have the potential for greater gains, as well as the potential for greater losses, than if the Fund had not invested in these instruments at all.
Service Shares Prospectus | GuidePath(R) Income Fund | Private Funds Risk Member  
Prospectus [Line Items] rr_ProspectusLineItems  
Risk [Text Block] rr_RiskTextBlock Private Funds Risk:  The Fund’s investment in private funds will require it to bear a pro rata share of the vehicles’ expenses, including management and performance fees.  The fees the Fund pays to invest in a private fund may be higher than if the manager of the private fund managed the Fund’s assets directly.  Furthermore, private funds, like the other Underlying Funds in which the Fund may invest, are subject to specific risks, depending on the nature of the vehicle, and also may employ leverage such that their returns are more than one times that of their benchmark which could amplify losses suffered by the Fund when compared to unleveraged investments.  Shareholders of the private funds are not entitled to the protections of the 1940 Act.  The majority of private funds permit redemptions only quarterly (although others are more frequent) and these withdrawal limitations restrict the Advisor’s ability to terminate investments in private funds. Additionally, because private funds are not publicly traded, the Fund’s investments in them may be more difficult to value than the Fund’s investments in publicly traded securities.
Service Shares Prospectus | GuidePath(R) Income Fund | Small And Medium Capitalization Company Risk Member  
Prospectus [Line Items] rr_ProspectusLineItems  
Risk [Text Block] rr_RiskTextBlock Small and Medium Capitalization Company Risk: Small and medium capitalization companies often have narrower markets, fewer products or services to offer and more limited managerial and financial resources than do larger, more established companies. As a result, their performance can be more volatile, and they face a greater risk of business failure, which could increase the volatility and risk of loss of the Fund’s assets.
Service Shares Prospectus | GuidePath(R) Income Fund | Derivatives Risk Member  
Prospectus [Line Items] rr_ProspectusLineItems  
Risk [Text Block] rr_RiskTextBlock Derivatives Risk: A derivative is an instrument with a value based on the performance of an underlying currency, security, index or other reference asset. The use of derivatives involves risks different from, or greater than, the risks associated with investing in more traditional investments. Derivatives involve costs, may create leverage, and may be illiquid, volatile, and difficult to value. The Fund may not be able to close out or sell a derivative position at a particular time or at an anticipated price. The use of derivatives could also result in a loss if the counterparty to the transaction does not perform as promised, including because of such counterparty’s bankruptcy or insolvency. The investment results achieved by the use of derivatives by the Fund may not match or fully offset changes in the value of the underlying currency, security, index or other reference asset that it was attempting to hedge or the investment opportunity the Fund was attempting to pursue.

Risk [Text Block] rr_RiskTextBlock Options Risk: The value of the Fund’s options positions will fluctuate in response to changes in the value of the underlying securities. Writing call options limits the opportunity to profit from an increase in the market value of stocks in exchange for up-front cash at the time of selling the call option. In addition, the Fund continues to bear the risk of declines in the underlying securities on which the option is written. When purchasing put options, the Fund risks losing all or part of the cash paid for purchasing the option. As the writer of a put option, the Fund has a risk of loss should the underlying securities decline in value. If the value of the underlying securities declines below the exercise price of the put option and the put option is exercised, the Fund, as the writer of the put option, will be required to buy the underlying securities at the exercise price, and the Fund will incur a loss to the extent that the current market value of the underlying securities is less than the exercise price of the put option. However, the loss will be offset in part by the premium received from the buyer of the put option. Unusual market conditions or the lack of a ready market for any particular option at a specific time may reduce the effectiveness of the Fund’s option strategies, and for these and other reasons the Fund’s option strategies may not reduce the Fund’s volatility to the extent desired.

Risk [Text Block] rr_RiskTextBlock Leverage Risk: The Fund’s investments in closed-end funds, leveraged ETFs and ETNs, and derivatives such as futures contracts, forward contracts and swaps have the economic effect of creating financial leverage. Financial leverage magnifies exposure to the swings in prices of an asset class underlying a derivatives instrument and results in increased volatility, which means the Fund will have the potential for greater gains, as well as the potential for greater losses, than if the Fund had not invested in derivatives at all.
Service Shares Prospectus | GuidePath(R) Income Fund | Debt/Fixed Income Securities Risk Member  
Prospectus [Line Items] rr_ProspectusLineItems  
Risk [Text Block] rr_RiskTextBlock Debt/Fixed Income Securities Risk: An increase in interest rates typically causes a fall in the value of the debt securities in which the Fund may invest. Conversely, very low or negative interest rates may heighten the Fund's susceptibility to interest rate risk and diminish yield and performance.The value of your investment in the Fund may change in response to changes in the credit ratings of the debt securities in the Fund's portfolio. Moreover, rising interest rates or lack of market participants may lead to decreased liquidity in the bond and loan markets, making it more difficult for the Fund to sell its holdings at a time when the Fund's manager might wish to sell. Lower rated securities ("junk bonds") are generally subject to greater risk of loss of your money than higher rated securities. Issuers may (increase) decrease prepayments of principal when interest rates (fall) increase, affecting the maturity of the debt security and causing the value of the security to decline. To the extent the Fund or an Underlying Fund invests in derivatives tied to fixed income markets, the Fund or Underlying Fund may be more substantially exposed to these risks than a fund that does not invest in derivatives.
Service Shares Prospectus | GuidePath(R) Income Fund | Marketplace Loan Risk Member  
Prospectus [Line Items] rr_ProspectusLineItems  
Risk [Text Block] rr_RiskTextBlock Marketplace Loan Risk: Investments in loans sourced through marketplace lending platforms are subject to additional risks than those applicable to investments in loans generally. An Underlying Fund may not have direct recourse against the borrower or may be otherwise limited in its ability to directly enforce its rights under the loan. Default history for alternative lending platforms is limited. Future defaults may be higher than historical defaults and the timing of defaults may vary significantly from historical observations. An Underlying Fund may have limited knowledge about the underlying loans to which it has exposure and is dependent upon the platform for information regarding the loans and borrowers’ credit information. Such information may be incomplete, inaccurate or outdated and may, therefore, not accurately reflect the borrowers’ actual creditworthiness. In addition, investments in loans sourced through a marketplace lending platform may also be negatively impacted if the platform or a third-party service provider becomes unable or unwilling to fulfill its obligations in servicing the loans.

Risk [Text Block] rr_RiskTextBlock U.S. Government Agency Obligations Risk: Government agency obligations have different levels of credit support and, therefore, different degrees of credit risk. Some securities issued by agencies and instrumentalities of the U.S. Government are supported by the full faith and credit of the United States, but others are neither insured nor guaranteed by the U.S. Government. For example, Connecticut Avenue Securities issued by the Federal National Mortgage Association and Structured Agency Credit Risk debt notes issued by the Federal Home Loan Mortgage Association carry no guarantee whatsoever and the risk of default associated with these securities would be borne by the Fund. The U.S. Department of the Treasury has the authority to provide financial support to these debt obligations, but no assurance can be given that the U.S. Government will do so.

The prices of convertible securities with longer maturities tend to be more volatile than those with shorter maturities. Value also tends to change whenever the market value of the underlying common or preferred stock fluctuates.

Risk [Text Block] rr_RiskTextBlock Loan Risk: Loans are subject to risk of loss as a result of borrower default, sensitivity to interest rate and economic changes, valuation difficulties and potential decreased liquidity to a greater extent than other types of investments. The value of any collateral securing a loan may decline, be insufficient to meet the borrower’s obligations, or be difficult or costly to liquidate. It may take longer than 7 days for investments in loans to settle, which may adversely affect an Underlying Fund’s ability to timely honor redemptions.
Service Shares Prospectus | GuidePath(R) Income Fund | Senior Loan Risk Member  
Prospectus [Line Items] rr_ProspectusLineItems  
Risk [Text Block] rr_RiskTextBlock Senior Loan Risk: Investments in senior loans are subject to loan risk generally. Senior loans typically are below investment grade and are considered speculative because of the credit risk of their issuers. Their issuers are more likely to default on their payments of interest and principal owed, and such defaults could reduce the Fund’s NAV and income distributions. In addition, the Fund may have to sell securities at lower prices than it otherwise would to meet cash needs or it may have to maintain a greater portion of its assets in cash equivalents than it otherwise would because of impairments and limited liquidity of the collateral supporting a senior loan, which could negatively affect the Fund’s performance. Newly originated variable rate securities (including reissuances and restructured loans) may possess lower levels of credit document protections than has historically been the case. Accordingly, in the event of default the Fund may experience lower levels of recoveries than has historically been the norm.

Risk [Text Block] rr_RiskTextBlock Portfolio Turnover Risk: Depending on market and other conditions, the Fund may experience a high portfolio turnover, which may result in higher brokerage costs and transaction costs (which could reduce investment returns). Distributions of net short-term capital gains are taxable as ordinary income when Fund shares are held in a taxable account. A fund with a high portfolio turnover rate (a measure of how frequently assets within a fund are bought and sold) is more likely to generate short-term capital gains than a fund with a low portfolio turnover rate.

Risk [Text Block] rr_RiskTextBlock Preferred Stock Risk: A preferred stock may decline in price, or fail to pay dividends when expected, because the issuer experiences a decline in its financial status. Preferred stocks often behave like debt securities, but have a lower payment priority than the issuer’s bonds or other debt securities. Therefore, they may be subject to greater credit risk than those of debt securities. Preferred stocks also may be significantly less liquid than many other securities, such as corporate debt or common stock.

Risk [Text Block] rr_RiskTextBlock Extension Risk: As interest rates rise, repayments of principal on certain debt securities, including, but not limited to, floating rate loans and mortgage-related securities, may occur at a slower rate than expected and the expected maturity of those securities could lengthen as a result. Securities that are subject to extension risk generally have a greater potential for loss when prevailing interest rates rise, which could cause their values to fall sharply. Interest-only and principal-only securities are especially sensitive to interest rate changes, which can affect not only their prices but can also change the income flows and repayment assumptions about those investments.

The Fund could also lose money in connection with securities lending transactions if it does not recover the loaned securities and/or the value of the collateral falls, including the value of investments made with cash collateral. Securities lending also may have certain adverse tax consequences. The Fund is not obligated to engage in securities lending, and may discontinue its securities lending activities at any time.

Strategy [Heading] rr_StrategyHeading Principal Investment Strategies of the Fund
Strategy Narrative [Text Block] rr_StrategyNarrativeTextBlock
The Fund invests primarily in a portfolio of actively and passively managed registered mutual funds, exchange-traded funds (“ETFs”), closed-end funds and business development companies (“BDCs”), in addition to direct investments. The funds in which the Fund may invest are referred to herein as the “Underlying Funds.” AssetMark, Inc. (“AssetMark” or the “Advisor”) believes that investing in Underlying Funds provides the Fund with an efficient means of creating a portfolio that provides investors with indirect exposure to a broad range of investments. By investing in the Fund, you will indirectly bear fees and expenses of the Underlying Funds in addition to the Fund’s direct fees and expenses. In order to obtain exposure to certain markets, asset classes or active management styles, the Fund may buy Underlying Funds managed by the Advisor or its affiliates, which, in turn, invest in various securities, including ETFs. The Fund may also invest directly in securities and other exchange-traded products, such as exchange-traded notes (“ETNs”).
The Advisor may invest in securities of companies of various market capitalizations. The Fund considers “large capitalization companies” to be companies, at the time of purchase, whose market capitalizations are within the range of the market capitalizations in the Russell 1000® Index. The Fund considers “small-to-medium capitalization companies” to be companies, at the time of purchase, whose market capitalizations are within the range of the market capitalizations in the Russell 2500TM Index.
The Advisor’s asset allocation decisions will be based on different factors and analytical approaches, derived from volatility-managed and income-focused asset allocation approaches. These approaches typically utilize fundamental and quantitative analyses of global market and economic conditions and assumptions regarding risks and returns. The Advisor seeks to create a portfolio that is optimized to seek high total return and income, managed to contain the potential magnitude of drawdowns in high volatility markets.
In pursuing the Fund’s objective, the Fund invests, either directly or indirectly via the Underlying Funds, in various types of domestic and international fixed income securities, domestic and international equity securities (including American Depositary Receipts (“ADRs”) and Global Depositary Receipts (“GDRs”)) and cash equivalent money market securities.
The asset classes in which the Fund may invest, either directly or indirectly via the Underlying Funds, include, but are not limited to, debt securities of governments, government agencies and supranational entities, debt securities of corporations, bank loans, convertible securities, mortgage- or asset-backed securities, inflation-linked securities and other securitized or collateralized debt obligations and higher-yielding bonds (sometimes referred to as “junk bonds”), including emerging market debt. The Fund may invest in debt securities of any maturity or quality. The Fund may invest in equity securities which include domestic and foreign common and preferred stock, convertible debt securities, American Depositary Receipts (“ADRs”), business development companies (“BDCs”), Master Limited Partnerships (“MLPs”), publicly traded real estate investment trusts (“REITs”), non-traded unregistered REITs, ETFs and pooled investment funds including private investment funds that are not registered under the 1940 Act (“private funds”) that provide exposure to pools of whole loans, including those sourced through peer-to-peer or marketplace lending platforms.
MLPs are businesses organized as limited partnerships that trade their proportionate shares of the partnership (units) on a public exchange.  MLPs are required to pay out most or all of their earnings in distributions. The Fund may invest up to 30% of its total assets in securities denominated in foreign currencies and may invest without limit in U.S. dollar-denominated securities of foreign issuers.
In selecting debt securities for the Fund, the Advisor develops an outlook for credit markets, interest rates, currency exchange rates and the economy, analyzes individual credit and prepayment risks, and uses other security selection techniques. The proportion of the Fund’s assets committed to investment in securities with particular characteristics (such as quality, sector, interest rate or maturity) varies based on the Advisor’s outlook for the U.S. economy and the economies of other countries in the world, the financial markets and other factors.
The Fund may allocate assets to ETFs that provide exposure to various fixed income and equity securities and sectors. Using this type of strategy, the Fund seeks to tactically avoid risk by reducing exposure to unattractive sectors at the appropriate times, while also increasing exposure to attractive sectors on a timely basis. The Fund may also invest in inverse, leveraged, and inverse-leveraged ETFs and ETNs. Inverse ETFs and ETNs are designed to correlate inversely with the performance of an index. Leveraged and inverse-leveraged ETFs and ETNs seek investment results that correspond to two or more times the performance of an index or inverse of the performance of an index, respectively.
The Fund may, at the discretion of the Advisor, engage in a strategy of purchasing and selling (writing) call and put options on indexes or ETFs (hereafter referred to as "call options" and "put options"). The writer of a call option receives cash (the “premium”) from the purchaser. In return, the purchaser of a call option has the right to any appreciation in the value of the underlying index or ETF over a fixed price (the “exercise price”) on a certain date in the future (the “expiration date”). If the purchaser does not exercise the option, the writer of the option retains the premium. If the purchaser exercises the option, the writer of the option pays the purchaser the difference between the value of the underlying index or ETF and the exercise price of the option.
The value of a call option generally increases as the prices of the stocks constituting the underlying index or ETF increase, and decreases as those stocks decrease in price. Conversely, the value of a put option generally increases as the prices of the stocks constituting the underlying index or ETF decrease, and decreases as those stocks increase in price. The premium, the exercise price and the value of the underlying index or ETF will determine the gain or loss realized by the Fund on a written or purchased option. When the Fund has written an option, it generally can repurchase the option prior to the expiration date, ending its obligation. In such case, the difference between the cost of repurchasing the option and the premium received will determine the gain or loss realized by the Fund. While writing call options may reduce the Fund’s volatility and provide a source of steady cash flow, it may also reduce the Fund’s ability to profit from increases in the value of the underlying index or ETF.
Using the proceeds from its written call options, the Fund may buy put options in an attempt to hedge against a significant market decline in the underlying index or ETF that may occur over a short period of time. In addition, the Fund may write call options or put options on the underlying indexes of the ETFs in which the Fund is invested.
The Fund may invest in Underlying Funds that use derivatives for risk management purposes or as part of their investment strategies. An Underlying Fund may use derivatives to earn income and enhance returns, to manage or adjust the risk and duration exposure profile of the Underlying Fund, to replace more traditional direct investments or to obtain exposure to certain markets, interest rates, sectors or individual issuers. The derivatives used by an Underlying Fund may allow the Underlying Fund to obtain net long or net negative (short) exposures to selected interest rates, countries, duration or credit risks. An Underlying Fund may also use derivatives to hedge or gain exposure to currencies. The Fund may also invest directly in futures contracts. The Fund may, at the discretion of the Advisor, use futures contracts as a means to implement a volatility-managed strategy. The Fund's volatility targeting component attempts to balance upside return potential
during periods of relative market stability while seeking to mitigate losses during periods of heightened market volatility.It is anticipated that the Fund may have net economic leverage of up to 30% of the Fund’s total assets through its investments in closed-end funds, leveraged ETFs and ETNs, and certain derivatives, such as options and futures contracts.
The Fund’s asset allocation mix among equity, fixed income and cash equivalent money market securities is intended to change frequently over time.  The Fund does not have a set target asset allocation mix among equities, fixed income securities and cash equivalent investments.  If the Advisor believes that the stock market conditions are unfavorable or overvalued, it may significantly increase the allocation to more defensive asset classes such as fixed income or cash equivalent securities.  The Advisor also has broad latitude to allocate assets to equity securities in pursuit of perceived opportunities for additional return.  Based on these judgments, the Fund’s asset allocation mix may significantly change over time in response to opportunities as they are identified. In certain circumstances the Fund may be substantially or fully invested in cash equivalent securities for an extended period of time.
The Fund lends its portfolio securities to seek to generate additional income.

Risk [Text Block] rr_RiskTextBlock Fund of Funds Risk: The Fund is subject to fund of funds risk, which means that the ability of the Fund to meet its investment objective is directly related to the ability of the Underlying Funds to meet their investment objectives.  There can be no assurance that either the Fund or the Underlying Funds will achieve their investment objectives. Additionally, each Fund may invest in other investment companies for which the Advisor or an affiliate serves as investment advisor (i.e., affiliated Underlying Funds). Such investments in the Underlying Funds could create a conflict of interest for the Advisor in managing the Fund’s assets. By investing in the Fund, you will indirectly bear fees and expenses of the Underlying Funds in addition to the Fund’s direct fees and expenses.

Risk [Text Block] rr_RiskTextBlock Mortgage- and Asset-Backed Securities Risk: Payments on mortgage- and asset-backed securities depend upon assets held by the issuer and collections on the underlying mortgages or loans. Issuers of asset-backed securities may have limited ability to enforce the security interest in the underlying assets, and credit enhancements provided to support the securities, if any, may be inadequate to protect investors in the event of default. Mortgage- and asset-backed securities are also subject to prepayment risk, which is the risk that the borrower will prepay some or all of the principal owed to the issuer. If that happens, a Fund may have to replace the security by investing the proceeds in a less attractive security. In certain market conditions, asset-backed securities may experience volatile fluctuations in value and periods of illiquidity.

The shares of closed-end funds frequently trade at a premium or discount relative to their net asset value, and many closed-end funds use leverage, or borrowed money, to try to increase returns. In addition, distributions by a closed-end fund may include a return of capital, which would reduce the fund’s net asset value and its earnings capacity. Finally, closed-end funds are allowed to invest in a greater amount of illiquid investments than open-end mutual funds.

Risk [Text Block] rr_RiskTextBlock Business Development Company Risk: BDCs are closed-end investment companies that have elected to register as BDCs. Shareholders bear both their proportionate share of the Fund’s expenses and similar expenses of the BDC when the fund invests in shares of the BDC. BDCs primarily invest in privately-held and small- to medium- capitalization public companies, and are generally considered to be non-rated or below investment grade. The fair values of these investments often are not readily determinable. This could cause the Fund’s investments in a BDC to be inaccurately valued, including overvalued. BDC revenues, income (or losses) and valuations can, and often do, fluctuate suddenly and dramatically, and they face considerable risk of loss. In addition, BDCs often borrow funds to make investments and, as a result, are exposed to the risks of leverage. Leverage magnifies the potential loss on amounts invested and therefore increases the risks associated with an investment in a BDC’s securities.

Junk bonds are subject to greater credit risk than higher-grade securities, have a greater risk of default and are considered speculative. Issuers of junk bonds are more likely to experience financial difficulties that may impair their ability to make principal and interest payments.
Service Shares Prospectus | GuidePath(R) Growth and Income Fund | Leveraged And Inverse ETF/ETN Risk Member  
Prospectus [Line Items] rr_ProspectusLineItems  
Risk [Text Block] rr_RiskTextBlock Leveraged and Inverse ETF/ETN Risk: Inverse ETFs/ETNs generally use derivatives and short sales that, in combination, are designed to produce returns that move in the opposite direction of the indices they track. To the extent the Fund invests in ETFs/ETNs that seek to provide investment results that are the inverse of the performance of an underlying index, the Fund will indirectly be subject to the risk that the performance of such ETF/ETN will fall as the performance of that ETF or ETN’s benchmark rises, a result that is the opposite from traditional mutual funds. The Fund’s use of leveraged and inverse-leveraged ETFs and ETNs has the economic effect of creating financial leverage. Financial leverage magnifies exposure to the swings in prices of an asset class and results in increased volatility, which means the Fund will have the potential for greater gains, as well as the potential for greater losses, than if the Fund had not invested in these instruments at all.
Service Shares Prospectus | GuidePath(R) Growth and Income Fund | Private Funds Risk Member  
Prospectus [Line Items] rr_ProspectusLineItems  
Risk [Text Block] rr_RiskTextBlock Private Funds Risk:  The Fund’s investment in private funds will require it to bear a pro rata share of the vehicles’ expenses, including management and performance fees.  The fees the Fund pays to invest in a private fund may be higher than if the manager of the private fund managed the Fund’s assets directly.  Furthermore, private funds, like the other Underlying Funds in which the Fund may invest, are subject to specific risks, depending on the nature of the vehicle, and also may employ leverage such that their returns are more than one times that of their benchmark which could amplify losses suffered by the Fund when compared to unleveraged investments.  Shareholders of the private funds are not entitled to the protections of the 1940 Act.  The majority of private funds permit redemptions only quarterly (although others are more frequent) and these withdrawal limitations restrict the Advisor’s ability to terminate investments in private funds. Additionally, because private funds are not publicly traded, the Fund’s investments in them may be more difficult to value than the Fund’s investments in publicly traded securities.
Service Shares Prospectus | GuidePath(R) Growth and Income Fund | Small And Medium Capitalization Company Risk Member  
Prospectus [Line Items] rr_ProspectusLineItems  
Risk [Text Block] rr_RiskTextBlock Small and Medium Capitalization Company Risk: Small and medium capitalization companies often have narrower markets, fewer products or services to offer and more limited managerial and financial resources than do larger, more established companies. As a result, their performance can be more volatile, and they face a greater risk of business failure, which could increase the volatility and risk of loss of the Fund’s assets.
Service Shares Prospectus | GuidePath(R) Growth and Income Fund | Derivatives Risk Member  
Prospectus [Line Items] rr_ProspectusLineItems  
Risk [Text Block] rr_RiskTextBlock Derivatives Risk: A derivative is an instrument with a value based on the performance of an underlying currency, security, index or other reference asset. The use of derivatives involves risks different from, or greater than, the risks associated with investing in more traditional investments. Derivatives involve costs, may create leverage, and may be illiquid, volatile, and difficult to value. The Fund may not be able to close out or sell a derivative position at a particular time or at an anticipated price. The use of derivatives could also result in a loss if the counterparty to the transaction does not perform as promised, including because of such counterparty’s bankruptcy or insolvency. The investment results achieved by the use of derivatives by the Fund may not match or fully offset changes in the value of the underlying currency, security, index or other reference asset that it was attempting to hedge or the investment opportunity the Fund was attempting to pursue.
Service Shares Prospectus | GuidePath(R) Growth and Income Fund | Options Risk Member  
Prospectus [Line Items] rr_ProspectusLineItems  
Risk [Text Block] rr_RiskTextBlock Options Risk: The value of the Fund’s options positions will fluctuate in response to changes in the value of the underlying securities. Writing call options limits the opportunity to profit from an increase in the market value of stocks in exchange for up-front cash at the time of selling the call option. In addition, the Fund continues to bear the risk of declines in the underlying securities on which the option is written. When purchasing put options, the Fund risks losing all or part of the cash paid for purchasing the option. As the writer of a put option, the Fund has a risk of loss should the underlying securities decline in value. If the value of the underlying securities declines below the exercise price of the put option and the put option is exercised, the Fund, as the writer of the put option, will be required to buy the underlying securities at the exercise price, and the Fund will incur a loss to the extent that the current market value of the underlying securities is less than the exercise price of the put option. However, the loss will be offset in part by the premium received from the buyer of the put option. Unusual market conditions or the lack of a ready market for any particular option at a specific time may reduce the effectiveness of the Fund’s option strategies, and for these and other reasons the Fund’s option strategies may not reduce the Fund’s volatility to the extent desired.

Service Shares Prospectus | GuidePath(R) Growth and Income Fund | Debt/Fixed Income Securities Risk Member  
Prospectus [Line Items] rr_ProspectusLineItems  
Risk [Text Block] rr_RiskTextBlock Debt/Fixed Income Securities Risk: An increase in interest rates typically causes a fall in the value of the debt securities in which the Fund may invest. Conversely, very low or negative interest rates may heighten the Fund's susceptibility to interest rate risk and diminish yield and performance.The value of your investment in the Fund may change in response to changes in the credit ratings of the debt securities in the Fund's portfolio. Moreover, rising interest rates or lack of market participants may lead to decreased liquidity in the bond and loan markets, making it more difficult for the Fund to sell its holdings at a time when the Fund's manager might wish to sell. Lower rated securities ("junk bonds") are generally subject to greater risk of loss of your money than higher rated securities. Issuers may (increase) decrease prepayments of principal when interest rates (fall) increase, affecting the maturity of the debt security and causing the value of the security to decline. To the extent the Fund or an Underlying Fund invests in derivatives tied to fixed income markets, the Fund or Underlying Fund may be more substantially exposed to these risks than a fund that does not invest in derivatives.

Risk [Text Block] rr_RiskTextBlock Marketplace Loan Risk: Investments in loans sourced through marketplace lending platforms are subject to additional risks than those applicable to investments in loans generally. An Underlying Fund may not have direct recourse against the borrower or may be otherwise limited in its ability to directly enforce its rights under the loan. Default history for alternative lending platforms is limited. Future defaults may be higher than historical defaults and the timing of defaults may vary significantly from historical observations. An Underlying Fund may have limited knowledge about the underlying loans to which it has exposure and is dependent upon the platform for information regarding the loans and borrowers’ credit information. Such information may be incomplete, inaccurate or outdated and may, therefore, not accurately reflect the borrowers’ actual creditworthiness. In addition, investments in loans sourced through a marketplace lending platform may also be negatively impacted if the platform or a third-party service provider becomes unable or unwilling to fulfill its obligations in servicing the loans.

Some securities issued by agencies and instrumentalities of the U.S. Government are supported by the full faith and credit of the United States, but others are neither insured nor guaranteed by the U.S. Government. For example, Connecticut Avenue Securities issued by the Federal National Mortgage Association and Structured Agency Credit Risk debt notes issued by the Federal Home Loan Mortgage Association carry no guarantee whatsoever and the risk of default associated with these

Risk [Text Block] rr_RiskTextBlock Loan Risk: The value of an investment in a loan is entirely dependent on the borrower’s continued and timely payments. If a borrower fails to make interest payments or repay principal when due on a loan in which the Fund has direct or indirect investment exposure, or if the value of a loan decreases, the value of the Fund’s investment will be adversely affected. Loans are subject to risk of loss as a result of borrower default, sensitivity to interest rate and economic changes, valuation difficulties and potential decreased liquidity to a greater extent than other types of investments. The value of any collateral securing a loan may decline, be insufficient to meet the borrower’s obligations, or be difficult or costly to liquidate. It may take longer than 7 days for investments in loans to settle, which may adversely affect an Underlying Fund’s ability to timely honor redemptions.

Securities that are subject to extension risk generally have a greater potential for loss when prevailing interest rates rise, which could cause their values to fall sharply.
