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 ended November 30, 2014, the Fund’s portfolio turnover rate was 591% of the average value of the portfolio.

Strategy Narrative [Text Block]

rr_StrategyNarrativeTextBlock

The Fund’s investment adviser, Horizon Investments, LLC (“Horizon”), seeks to achieve the Fund’s investment objective by allocating assets across various sectors of the global securities markets. Horizon executes this strategy by investing primarily in exchange-traded funds (“ETFs”) that each invests primarily in one of the following asset classes:

• U.S. Common Stocks

• Foreign Developed Market Common Stocks

• Emerging Market Common Stocks

• Commodities

• Currencies

• Government Bonds

• Corporate Bonds

• Real Estate Investment Trusts (REITS)

• International Bonds

• Municipal Bonds

• High Yield Bonds

Horizon selects ETFs without restriction as to the issuer country, capitalization, currency, or maturity or credit quality of the securities held by each ETF. For purposes of measuring allocation of assets, the Fund looks through to the holdings of each ETF. Under normal market conditions, the Fund invests a majority of its assets in ETFs that invest primarily in equity securities. An ETF may hold a majority of its assets in lower-quality fixed income securities commonly known as “high yield” or “junk” bonds. Junk bonds are generally rated lower than Baa3 by Moody’s Investors Service (“Moody’s”) or lower than BBB- by Standard and Poor’s Rating Group (“S&P”). Capital appreciation, if any, generally arises from decreases in interest rates, foreign currency appreciation or improving credit fundamentals for a particular sector or security.

Horizon selects asset classes using a tactical approach that allocates the Fund’s portfolio between asset classes that Horizon believes have the highest expected return for a given amount of risk. Tactical investing strategies seek to maximize returns by adjusting portfolio asset-allocations among various asset classes based upon near-term forecasts. Horizon assesses expected return and risk using a multi-disciplined approach consisting of economic, quantitative and fundamental analysis. A representative ETF is selected for inclusion in the portfolio after it is reviewed for sufficient trading liquidity and fit within overall portfolio diversification needs. By selecting ETFs using this process, Horizon expects that the Fund will typically hold no more than 30 ETF positions. Horizon may also invest in non-ETF securities, when it believes they may offer higher return and/or lower risk than an ETF or when Horizon believes an individual security will provide strategic exposure to a specific sector or market segment. Horizon expects to engage in frequent buying and selling of securities to achieve the Fund’s investment objective.

Risk Narrative [Text Block]

rr_RiskNarrativeTextBlock

Many factors affect the Fund’s performance. The Fund’s share price changes daily based on changes in market conditions in response to economic, political and financial developments. The direction and extent of those price changes will be affected by the financial condition, industry and economic sector, and geographic location of the securities held by ETFs in which the Fund invests. The Fund is not federally insured or guaranteed by any government agency. YOU MAY LOSE MONEY BY INVESTING IN THE FUND.

Commodity Risk: Investing in commodity-linked ETFs may subject the Fund to greater volatility than investments in traditional securities. Commodity prices may be influenced by unfavorable weather, animal and plant disease, geologic and environmental factors as well as changes in government regulation.

Debt Securities Risk: When ETFs invest in bonds, the value of your investment in the Fund will fluctuate with changes in interest rates. Longer-term bonds are generally more sensitive to interest rate changes than short-term bonds and therefore may carry more risk. Issuers of fixed-income securities may default on interest and principal payments. Generally, securities with lower debt ratings (“junk bonds”) have greater credit risk.

ETF Risk: You will indirectly pay fees and expenses charged by the ETFs in addition to the Fund’s direct fees and expenses. As a result, the cost of investing in the Fund will be higher than the cost of investing directly in ETF shares and may be higher than other mutual funds that invest directly in stocks and bonds. Each ETF is subject to specific risks, depending on the nature of the fund. These risks could include sector risk (increased risk from a focus on one or more sectors of the market), as well as risks associated with fixed income securities, foreign currencies and commodities.

Foreign Currency Risk: Foreign currency-linked ETFs risks include market risk, credit risk and country risk. Market risk results from adverse changes in exchange rates in the currencies in which the ETF is long or short. Credit risk results because a currency-trade counterparty may default. Country risk arises because a government may interfere with transactions in its currency.

Foreign Securities Risk: Foreign securities may be riskier than U.S. investments because of factors such as unstable international political and economic conditions, currency fluctuations, foreign controls on investment and currency exchange, withholding taxes, a lack of adequate company information, less liquid and more volatile markets, and a lack of governmental regulation. Foreign companies generally are not subject to accounting, auditing, and financial reporting standards comparable to those applicable to U.S. companies. Transaction costs and costs associated with custody services are generally higher for foreign securities than they are for U.S. securities. Sovereign issuers may lack sufficient revenue to repay debts or may repudiate debts despite an ability to repay.

○ Emerging Markets Risk: In addition to the risks generally associated with investing in securities of foreign companies, countries with emerging markets also may have relatively unstable governments, social and legal systems that do not protect shareholders, economies based on only a few industries, and securities markets that trade a small number of issues.

Management Risk: The ability of the Fund to meet its investment objective is directly related to the allocation of the Fund’s assets. Horizon may allocate the Fund’s investments so as to under-emphasize or over-emphasize investments under the wrong market conditions, in which case the Fund’s value may be adversely affected.

Market Risk: Investments in securities in general are subject to market risks that may cause their prices to fluctuate over time. The Fund’s investments may decline in value due to factors affecting securities markets generally, or particular countries, segments, economic sectors, industries or companies within those markets. The value of a security may decline due to general economic and market conditions that are not specifically related to a particular issuer.

Real Estate Risk: Real estate values rise and fall in response to a variety of factors, including local, regional and national economic conditions, interest rates and tax considerations. REIT performance depends on the types and locations of the rental properties it owns and on how well it manages those properties.

Smaller and Medium Issuer Risk: Investments in ETFs that own small and medium capitalization companies and direct investments in individual small and medium capitalization companies may be more vulnerable than larger, more established organizations to adverse business or economic developments.

Turnover Risk: Higher portfolio turnover will result in higher transactional and brokerage costs.

Strategy Narrative [Text Block]

rr_StrategyNarrativeTextBlock

The Fund’s investment adviser, Horizon Investments, LLC (“Horizon”), uses a multi-discipline active asset allocation investment approach. Horizon allocates the Fund’s assets across various sectors of the global securities markets. In addition, Horizon seeks to mitigate downside risk through its “Risk Assist” overlay. Risk Assist is an active risk reduction strategy intended to guard against large declines in an equity portfolio.

Global Securities Strategy

Horizon executes its active allocation strategy by investing primarily in exchange-traded funds (“ETFs”) that each invests primarily in one of the following asset classes:

• U.S. Common Stocks

• Foreign Developed Market Common Stocks

• Emerging Market Common Stocks

• Commodities

• Currencies

• Government Bonds

• Corporate Bonds

• Real Estate Investment Trusts (REITS)

• International Bonds

• Municipal Bonds

• High Yield Bonds

Horizon selects ETFs without restriction as to the issuer country, capitalization, currency, or maturity or credit quality of the securities held by each ETF. Under normal market conditions, the Fund invests a majority of its assets in ETFs that invest primarily in equity securities. The Fund may invest in ETFs that invest primarily in lower-quality fixed income securities commonly known as “high yield” or “junk” bonds. Junk bonds are generally rated lower than Baa3 by Moody’s Investors Service (“Moody’s”) or lower than BBB- by Standard and Poor’s Rating Group (“S&P”). Additionally, Horizon may select leveraged ETFs to magnify the returns associated with an asset class. The Fund may invest up to 10% of its assets in leveraged ETFs.

Horizon selects asset classes using a tactical approach that allocates the Fund’s portfolio among asset classes that Horizon believes have the highest expected return for a given amount of risk. Tactical investing strategies seek to maximize returns by adjusting portfolio asset-allocations among various asset classes based upon near-term forecasts. Horizon assesses expected return and risk using a multi-disciplined approach consisting of economic, quantitative and fundamental analysis. A representative ETF is selected for inclusion in the portfolio after it is reviewed for sufficient trading liquidity and fit within overall portfolio diversification needs. By selecting ETFs using this process, Horizon expects that the Fund will typically hold no more than 30 ETF positions. The Fund may also invest in the underlying securities that comprise an ETF if the ETF lacks sufficient liquidity or when Horizon believes investing directly in the underlying securities is more efficient. The Fund may also invest in non-ETF securities, including in instances where Horizon believes such securities offer higher return and/or lower risk than an ETF, that an ETF lacks sufficient liquidity, or that an individual security may provide strategic exposure to a specific sector or market segment. Horizon expects to engage in frequent buying and selling of securities to achieve the Fund’s investment objective.

Additional Overlay: Risk Assist Strategy

Under the Risk Assist strategy, Horizon continually measures market conditions with a specific focus on characteristics that indicate abnormal, severe risk conditions, in order to apply a proprietary process that prompts a risk reduction of the portfolio. Horizon executes this strategy by investing up to 100% of the Fund’s portfolio in Treasury bonds, Treasury notes, Treasury Inflated Protection Securities (“U.S. Treasury Securities”), U.S. government money market funds, exchange traded futures and options on U.S. Treasury Securities, and Repurchase agreements fully collateralized by U.S. Treasury Securities. Horizon may also select inverse ETFs, and options and futures on individual securities, ETFs or indexes to hedge against market declines or generate returns from falling asset prices. Inverse ETFs are designed to produce results opposite to market trends.

Risk Narrative [Text Block]

rr_RiskNarrativeTextBlock

Many factors affect the Fund’s performance. The Fund’s share price changes daily based on changes in market conditions in response to economic, political and financial developments. The direction and extent of those price changes will be affected by the financial condition, industry and economic sector, and geographic location of the securities held by ETFs in which the Fund invests. The Fund is not Federally insured or guaranteed by any government agency. YOU MAY LOSE MONEY BY INVESTING IN THE FUND.

Commodity Risk: Investing in commodity-linked ETFs may subject the Fund to greater volatility than investments in traditional securities. Commodity prices may be influenced by unfavorable weather, animal and plant disease, geologic and environmental factors as well as changes in government regulation.

Credit Risk: Issuers may not make interest or principal payments on securities, resulting in losses to the Fund. In addition, the credit quality of securities held by the Fund may be lowered if an issuer’s financial condition changes, including the U.S. government.

Debt Securities Risk: When the Fund invests in bonds (either directly or through ETFs), the value of your investment in the Fund will fluctuate with changes in interest rates. Longer-term bonds are generally more sensitive to interest rate changes than short-term bonds and therefore may carry more risk. Issuers of fixed-income securities may default on interest and principal payments. Generally, securities with lower debt ratings (“junk bonds”) have greater credit risk.

Derivatives Risk: Futures and options involve risks different from, or possibly greater than the risks associated with investing directly in securities including leverage risk, tracking risk and counterparty default risk in the case of over the counter derivatives. Option positions may expire worthless exposing the Fund to potentially significant losses.

ETF Risk: You will indirectly pay fees and expenses charged by the ETFs in addition to the Fund’s direct fees and expenses. As a result, the cost of investing in the Fund will be higher than the cost of investing directly in ETF shares and may be higher than other mutual funds that invest directly in stocks and bonds. Each ETF is subject to specific risks, depending on the nature of the fund. These risks could include sector risk (increased risk from a focus on one or more sectors of the market), as well as risks associated with fixed income securities, foreign currencies and commodities.

Foreign Currency Risk: Foreign currency-linked investment risk includes market risk, credit risk and country risk. Market risk results from adverse changes in exchange rates in the currencies in which the ETF is long or short. Credit risk results because a currency-trade counterparty may default. Country risk arises because a government may interfere with transactions in its currency.

Foreign Securities Risk: Foreign securities may be riskier than U.S. investments because of factors such as unstable international political and economic conditions, currency fluctuations, foreign controls on investment and currency exchange, withholding taxes, a lack of adequate company information, less liquid and more volatile markets, and a lack of governmental regulation. Foreign companies generally are not subject to accounting, auditing, and financial reporting standards comparable to those applicable to U.S. companies. Transaction costs and costs associated with custody services are generally higher for foreign securities than they are for U.S. securities. Sovereign issuers may lack sufficient revenue to repay debts or may repudiate debts despite an ability to repay.

○ Emerging Markets Risk: In addition to the risks generally associated with investing in securities of foreign companies, countries with emerging markets also may have relatively unstable governments, social and legal systems that do not protect shareholders, economies based on only a few industries, and securities markets that trade a small number of issues.

Foreign Issuer Risk: ETFs investing in securities of foreign companies may involve risks not typically associated with investing in U.S. issuers. Foreign markets can be more volatile than the U.S. market due to increased risks of adverse issuer, political, regulatory, market, or economic developments and can perform differently from the U.S. market.

High Yield or Junk Bond Risk: Lower-quality fixed income securities, known as “high yield” or “junk” bonds, present a significant risk for loss of principal and interest. These bonds offer the potential for higher return, but also involve greater risk than bonds of higher quality, including an increased possibility that the bond’s issuer, obligor or guarantor may not be able to make its payments of interest and principal (credit quality risk).

Limited History of Operations Risk: The Fund has a limited history of operations for investors to evaluate.

Management Risk: The ability of the Fund to meet its investment objective is directly related to the allocation of the Fund’s assets. Horizon may allocate the Fund’s investments so as to under-emphasize or over-emphasize investments under the wrong market conditions, in which case the Fund’s value may be adversely affected.

Market Risk: Investments in securities in general are subject to market risks that may cause their prices to fluctuate over time. The Fund’s investments may decline in value due to factors affecting securities markets generally, or particular countries, segments, economic sectors, industries or companies within those markets. The value of a security may decline due to general economic and market conditions that are not specifically related to a particular issuer.

Municipal Securities Risk : Changes in the financial health of a municipality may make it difficult for it to make interest and principal payments when due. Changes in the financial condition of one or more municipal issuers may affect the overall municipal securities market.

Real Estate Risk: Real estate values rise and fall in response to a variety of factors, including local, regional and national economic conditions, interest rates and tax considerations. REIT performance depends on the types and locations of the rental properties it owns and on how well it manages those properties.

Smaller and Medium Issuer Risk: Investments in ETFs that own small and medium capitalization companies and direct investments in individual small and medium capitalization companies may be more vulnerable than larger, more established organizations to adverse business or economic developments.

Turnover Risk: Higher portfolio turnover will result in higher transactional and brokerage costs.
