Expense Example, Narrative	rr_ExpenseExampleNarrativeTextBlock	This example is intended to help you compare the cost of investing in the Fund with the cost of investing in other mutual funds. The example assumes that you invest $10,000 in the Fund for the time periods indicated and then, except as indicated, redeem all of your shares at the end of those periods. The example also assumes that your investment has a 5% return each year and that the Fund's operating expenses remain the same (reflecting the contractual fee waiver).  Although your actual costs may be higher or lower, based on these assumptions your costs would be:

Investment Strategy, Heading	rr_StrategyHeading	The Fund's Principal Investment Strategies
Investment Strategy, Narrative	rr_StrategyNarrativeTextBlock	The Fund's sub-advisor, Analytic Investors, LLC ("Analytic"), seeks to achieve the Fund's investment goal by investing the Fund's assets in a combination of equity securities, high quality short-term debt securities and derivative instruments.    Equity Strategy.  The Fund normally invests at least 80% of its assets in equity securities.  This is a non-fundamental investment policy that can be changed by the Fund upon 60 days' prior notice to shareholders.  The Fund invests primarily in long and short positions in U.S. large cap stocks included in the Russell 1000® Index, although the Fund may invest in small and mid-cap equity securities.  The Fund buys securities "long" that Analytic believes will outperform and sells securities "short" that Analytic believes will underperform.  The Fund intends to take long and short equity positions that may vary over time based on Analytic's assessment of market conditions and other factors.  The Fund's long equity exposure is ordinarily expected to range from 80% to 130% and its short equity exposure from 0% to 70% of the Fund's net assets, excluding cash.  The Fund may take short positions at the higher end of this range when it has reduced its written call options positions under the options strategy (as described below) and may during these periods hold a substantial portion of the Fund's total assets in high quality short-term debt securities, cash or cash equivalents. Analytic selects common stocks and other equity securities for the Fund using a proprietary system that ranks securities according to a quantitative model.  The model attempts to determine a security's intrinsic value by evaluating variables such as relative valuation, price momentum, company fundamentals, liquidity and risk. Options Strategy.  Analytic seeks to reduce the overall portfolio risk through the use of options.  The Fund's options strategy primarily focuses on the use of writing (selling) call options on equity indexes or index exchange traded funds ("ETFs").  For these purposes, the Fund treats options on indexes and ETFs as being written on securities having an aggregate value equal to the face or notional amount of the index or ETF subject to the option.  The Fund may sell call options on broad-based domestic equity indexes or ETFs, such as the S&P 100® Index, as well as on narrower market indexes or ETFs or on indexes or ETFs of companies in a particular industry or sector.  The Fund may also sell call options on foreign indexes or ETFs.  The Fund seeks to write options on broad and narrow-based indexes and ETFs that correlate with the price movements of the Fund's equity securities. The Fund may also buy index put options to help protect the Fund from market declines that may occur in the future as the value of index put options increases as the prices of the stocks constituting the index decrease.  However, during periods of market appreciation, the value of the index put option decreases as these stocks increase in price.  The Fund may also write (sell) covered call options on individual equity securities.  The Fund may also purchase put options on individual equity securities which it owns.    Other Derivative Strategies.  In addition to the options strategy, the Fund may use other derivatives for a variety of purposes, including to: hedge against market and other risks in the portfolio; manage cash flows; and maintain market exposure and adjust the characteristics of its investments to more closely approximate those of its benchmark, with reduced transaction costs.  Analytic may also use futures contracts to seek to gain broad market exposure and/or to hedge against market and other risks in the Fund's portfolio. The Fund may engage in frequent and active trading of securities as part of its principal investment strategy.  Analytic generally considers selling a security when it reaches fair value estimate, when the company's fundamentals do not appear to justify the current price, when there has been or there is an expectation of an adverse change in the company's fundamentals, when the risks of the security unexpectedly rise, or when other investment opportunities appear more attractive.
Risk, Heading	rr_RiskHeading	The Principal Risks
Risk, Narrative	rr_RiskNarrativeTextBlock	The Fund's shares will fluctuate.  You could lose money on your investment in the Fund and the Fund could return less than other investments.  The Fund is subject to the principal risks summarized below.    Covered Call Options Risk:  Investments in covered calls involve certain risks. These risks include: o    Limited Gains.  When the Fund writes a covered call option, the Fund makes an obligation to deliver a security it already owns at an agreed-upon strike price on or before a predetermined date in the future in return for a premium. By selling a covered call option, the Fund may forego the opportunity to benefit from an increase in the price of the underlying stock above the exercise price, but continues to bear the risk of a decline in the value of the underlying stock.  While the Fund receives a premium for writing the call option, the price the Fund realizes from the sale of stock upon exercise of the option could be substantially below its prevailing market price. o    Lack of Liquidity for the Option.  A liquid market may not exist for the option.  If the Fund is not able to close out the options transaction, the Fund will not be able to sell the underlying security until the option expires or is exercised. o    Lack of Liquidity for the Security.  The Fund's investment strategy may also result in a lack of liquidity of the purchase and sale of portfolio securities.  Because the Fund will generally hold the stocks underlying the call option, the Fund may be less likely to sell the stocks in its portfolio to take advantage of new investment opportunities.    Derivatives Risk:  The Fund may invest in derivatives, such as futures and options contracts, options related to futures contracts or swap contracts, to pursue its investment goal. The use of such derivatives may expose the Fund to additional risks to which it would otherwise not be subject.  The lack of a liquid secondary market for a particular derivative instrument may prevent the Fund from closing its derivative positions and could adversely impact its ability to achieve its goals and to realize profits or limit losses.  Since transactions in derivatives may involve leverage, a relatively small price movement in a derivative may result in an immediate and substantial loss to the Fund.    Equity Securities Risk:  The Fund is subject to the risk that stock prices will fall (or rise with respect to short positions) over short or extended periods of time.  Individual companies may report poor results or be negatively affected by industry and/or economic trends and developments. The prices of securities issued by these companies may decline in response to such developments, which could result in a decline in the value of the Fund's shares.  Conversely, the risk of price increases with respect to securities sold short will also cause a decline in the value of the Fund's shares.    Market Risk: Market risk is the risk that the market value of a security may fluctuate, sometimes rapidly and unpredictably. Management Risk: The value of your investment may decrease if the sub-advisor's judgment about the attractiveness, value or market trends affecting a particular security, issuer, industry or sector or about market movements is incorrect. Large Cap Risk: Large cap risk is the risk that stocks of larger companies may underperform relative to those of small and mid-sized companies.  Larger, more established companies may be unable to respond quickly to new competitive challenges, such as changes in technology and consumer tastes.  Many larger companies may not be able to attain the high growth rate of successful smaller companies, especially during extended periods of economic expansion. Mid Cap Risk:  While the Fund primarily invests in large capitalization companies, the Fund may invest in mid-sized companies.  The Fund is subject to the risk that medium capitalization stocks may underperform other types of stocks or the equity markets as a whole. Stocks of mid-sized companies may be subject to more abrupt or erratic market movements than stocks of larger, more established companies. Mid-sized companies may have limited product lines or financial resources, and may be dependent upon a particular niche of the market.    Small Cap Risk:  While the Fund primarily invests in large capitalization companies, the Fund may invest in small capitalization companies.  The Fund is subject to the risk that small capitalization stocks may underperform other types of stocks or the equity markets as a whole. Small cap stock risk is the risk that stocks of smaller companies may be subject to more abrupt or erratic market movements than stocks of larger, more established companies. Small companies may have limited product lines or financial resources, or may be dependent upon a small or inexperienced management group. In addition, small cap stocks typically are traded in lower volume, and their issuers typically are subject to greater degrees of changes in their earnings and prospects.    Futures Contracts Risk:  A futures contract provides for the future sale by one party and purchase by another party of a specified quantity of the security or other financial instrument at a specified price and time.  A futures contract on an index is an agreement in which two parties agree to take or make delivery of an amount of cash equal to the difference between the value of the index at the close of the last trading day of the contract and the price at which the index contract was originally written.  The risks associated with futures include: the potential inability to terminate or sell a position, the lack of a liquid secondary market for the Fund's position and the risk that the counterparty to the transaction will not meet its obligations.                                          Foreign Securities Risk: Investing in foreign securities poses additional risks since political and economic events unique in a country or region will affect those markets and their issuers. These events will not necessarily affect the U.S. economy or similar issuers located in the United States. Index and ETF Call Options:  Writing index and ETF call options is intended to reduce the Fund's volatility and provide income, although it may also reduce the Fund's ability to profit from increases in the value of its equity portfolio.    Portfolio Turnover Risk: The risk that high portfolio turnover is likely to lead to increased Fund expenses that may result in lower investment returns. High portfolio turnover is also likely to result in higher short-term capital gains taxable to shareholders. Sector Focus Risk: The Fund may focus its investments in certain industries within certain sectors.  A fund that focuses its investments in the securities of a particular market sector is subject to the risk that adverse circumstances will have a greater impact on the fund than a fund that does not focus its investments in a particular sector. It is possible that economic, business or political developments or other changes affecting one security in the area of focus will affect other securities in that area of focus in the same manner, thereby increasing the risk of such investments. Short Sales Risk:  When selling a security short, the Fund will sell a security it does not own at the then-current market price.  The Fund borrows the security to deliver to the buyer and is obligated to buy the security at a later date so it can return the security to the lender.  If a security sold short increases in price, the Fund may have to cover its short position at a higher price than the short sale price, resulting in a loss.  To borrow the security, the Fund also may be required to pay a premium, which would increase the cost of the security sold short.  The amount of any gain will be decreased, and the amount of any loss increased, by the amount of the premium, dividends, interest or expenses the Fund may be required to pay in connection with the short sale.  In addition, a lender may request, or market conditions may dictate, that securities sold short be returned to the lender on short notice, and the Fund may have to buy the securities sold short at an unfavorable price.  If this occurs, any anticipated gain to the Fund may be reduced or eliminated or the short sale may result in a loss.  In addition, because the Fund's loss on a short sale arises from increases in the value of the security sold short, such loss is theoretically unlimited.  By contrast, the Fund's loss on a long position arises from decreases in the value of the security and is limited by the fact that a security's value cannot drop below zero. Leverage Risk:  By engaging in certain derivative strategies or investing the proceeds received from selling securities short, the Fund is employing leverage, which creates special risks.  The use of leverage may increase the Fund's exposure to long or short equity positions and make any change in the Fund's net asset value greater than without the use of leverage.  Leverage generally results in increased volatility of returns. Tax Consequences:  The Fund expects to generate premiums from its sale of call options.  These premiums typically will result in short-term capital gains to the Fund for federal and state income tax purposes.  Transactions involving the disposition of the Fund's underlying securities (whether pursuant to the exercise of a call option or otherwise) will give rise to capital gains or losses.  Due to the tax treatment of securities on which call options have been written, the holding period of the underlying security may be affected and some or all of the gains from the sale of the underlying security may be short-term capital gains.  Short-term capital gains are usually taxable as ordinary income when distributed to shareholders.  Because the Fund does not have control over the exercise of the call options it writes, shareholder redemptions or corporate events involving its equity securities investments (such as mergers, acquisitions, or reorganizations) may force it to realize capital gains or losses at inopportune times.    As with any mutual fund, there is no guarantee that the Fund will achieve its investment goal. You can find more information about the Fund's investments and risks under the "Investment Strategies and Risks" section of the Fund's Prospectus.

[2] Touchstone Advisors and the Trust have entered into an expense limitation agreement whereby Touchstone Advisors has contractually agreed to waive a portion of its fees and/or reimburse certain Fund expenses in order to limit annual fund operating expenses to 1.55%, 2.30%, 1.30% and 1.25% for Class A shares, Class C shares, Class Y shares and Institutional shares, respectively. This expense limitation will remain in effect until at least April 16, 2014 but can be terminated by a vote of the Board of Trustees of the Fund if they deem the termination to be beneficial to the Fund shareholders. Touchstone Advisors is entitled to recover, subject to approval by the Board of Trustees of the Fund, such amounts reduced or reimbursed for a period of up to three (3) years from the year in which Touchstone Advisors reduced its compensation and/or assumed expenses for the Fund. No recoupment will occur unless the Fund's expenses are below the expense limitation. See the discussion entitled "Contractual Fee Waiver Agreement" under the section entitled "The Funds' Management" in the Fund's prospectus for more information.
