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. 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 275% of the average value of its portfolio.

Expenses Deferred Charges [Text Block]

rr_ExpensesDeferredChargesTextBlock

Generally, Class A Shares are not subject to any charges by the Fund when redeemed; however, a contingent deferred sales charge may be imposed on certain redemptions (i) within 18 months on exchanges from a Virtus non-money market fund into a Virtus money market fund; and (ii) on purchases on which a finder’s fee has been paid. The 18-month period begins on the last day of the month preceding the month in which the purchase was made. The deferred sales charge is imposed on Class C Shares redeemed during the first year only.

Expense Example Narrative [Text Block]

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 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 and that the expense reimbursement arrangement remains in place only for the period indicated. Although your actual costs may be higher or lower, based on these assumptions your costs would be:

Strategy Narrative [Text Block]

rr_StrategyNarrativeTextBlock

The fund allocates net assets to multiple asset classes including: U.S. Equity, International Equity, Fixed Income, and Alternative. Allocations within each asset class are based on proprietary quantitative models.

The U.S. Equity allocation may be invested in ETFs and/or securities representing the primary sectors of the S&P 500® Index. The primary sectors of the S&P 500® Index are: consumer discretionary, consumer staples, energy, financials, healthcare, industrials, materials, technology, and utilities. The International Equity allocation may be invested in ETFs and/or securities representing both developed markets (EAFE) and emerging markets. The Fixed Income allocation may be invested in ETFs and/or securities representing fixed income sectors including: high yield, investment grade corporate, mortgages, intermediate treasuries and inflation-protected treasuries (TIPS). The Alternative allocation may be invested in ETFs and/or securities representing gold, real estate and broad-based equity securities. The fund may also invest in stocks (without restriction as to market capitalization), bonds (without restriction as to credit quality) and short-term securities. The fund may invest in a basket of securities to represent a sector if it determines that investment in the ETF for that sector is not feasible or otherwise not in the best interest of the fund. The fund may also deviate from a model allocation if it is determined that tracking the model allocation is likely to violate applicable legal or regulatory restrictions or otherwise result in adverse consequences for the fund. In times of market weakness, the fund has the ability to move partially or fully to short-term cash equivalents.

Risk Narrative [Text Block]

rr_RiskNarrativeTextBlock

The fund may not achieve its objective, and it is not intended to be a complete investment program. The value of the fund’s investments that supports your share value may decrease. If between the time you purchase shares and the time you sell shares the value of the fund’s investments decreases, you will lose money. Investment values can decrease for a number of reasons. Conditions affecting the overall economy, specific industries or companies in which the fund invests can be worse than expected, and investments may fail to perform as the subadviser expects. As a result, the value of your shares may decrease. Purchase and redemption activities by fund shareholders may impact the management of the fund and its ability to achieve its investment objective(s). The redemption by one or more large shareholders or groups of shareholders of their holdings in the fund could have an adverse impact on the remaining shareholders in the fund including by accelerating the realization of capital gains and increasing the fund's transaction costs. In addition, you will also be subject to the risks associated with the principal investment strategies of any ETFs in which the fund invests. The principal risks of investing in the fund are:

>

Commodity and Commodity-linked Instruments Risk. The risk that investments in commodities or commodity-linked notes will subject the fund’s portfolio to greater volatility than investments in traditional securities, or that commodity-linked instruments will experience returns different from the commodities they attempt to track.

>

Credit Risk. The risk that the issuer of a security will fail to pay interest or principal in a timely manner, or that negative perceptions of the issuer’s ability to make such payments will cause the price of the security to decline.

>

Emerging Market Investing Risk. The risk that prices of emerging markets securities will be more volatile, or will be more greatly affected by negative conditions, than those of their counterparts in more established foreign markets.

>

Equity Securities Risk. The risk that events negatively affecting issuers, industries or financial markets in which the fund invests, will impact the value of the stocks held by the fund and thus, the value of the fund’s shares over short or extended periods. Investments in a particular style or in small or medium-sized companies may enhance that risk.

>

Exchange-Traded Funds (ETFs) Risk. The risk that the value of an ETF will be more volatile than the underlying portfolio of securities the ETF is designed to track, or that the costs to the fund of owning shares of the ETF will exceed those the fund would incur by investing in such securities directly.

>

Foreign Investing Risk. The risk that the prices of foreign securities in the fund’s portfolio will be more volatile than those of domestic securities, or will be negatively affected by currency fluctuations or economic, political or other developments.

>

High-Yield/High-Risk Fixed Income Securities (Junk Bonds) Risk. The risk that the issuers of high-yield/ high-risk securities in the fund’s portfolio will default, that the prices of such securities will be volatile, and that the securities will not be liquid.

>

Interest Rate Risk. The risk that when interest rates rise, the values of the fund’s debt securities, especially those with longer maturities, will fall.

>

Market Volatility Risk. The risk that the value of the securities in which the fund invests may go up or down in response to the prospects of individual companies and/or general economic conditions. Price changes may be temporary or may last for extended periods.

>

Model Portfolio Risk. The risk that investments selected using quantitative models may perform differently from the market as a whole or from their expected performance. There can be no assurance that use of a quantitative model will enable the fund to achieve positive returns or outperform the market.

>

Portfolio Turnover Risk. The risk that the fund’s principal investment strategies will result in a consistently high portfolio turnover rate. See the Portfolio Turnover section above for more information about the impact that portfolio turnover can have on fund performance.

>

Real Estate Investment Risk. The risk that the value of the fund’s shares will be negatively affected by factors specific to the real estate market, including interest rate risk, leverage risk, property risk and management risk.

>

Sector Focused Investing Risk. The risk that events negatively affecting a particular industry or market sector in which the fund focuses its investments will cause the value of the fund’s shares to decrease, perhaps significantly. To the extent that the fund invests a significant portion of its portfolio in ETFs representing one or more of the primary sectors of the S&P 500 ® Index (such as consumer discretionary, energy, healthcare) or in an ETF representing U.S. Treasuries, the fund is more vulnerable to conditions that negatively affect such sectors as compared to a fund that is not significantly invested in such sectors.

>

U.S. Government Securities Risk. The risk that U.S. Government securities in the fund’s portfolio will be subject to price fluctuations, or that an agency or instrumentality will default on an obligation not backed by the full faith and credit of the United States.

rr_PerformanceTableExplanationAfterTaxHigher

In certain cases, the Return After Taxes on Distributions and Sale of Fund Shares for a period may be higher than other return figures for the same period. This will occur when a capital loss is realized upon the sale of fund shares and provides an assumed tax benefit that increases the return.

Performance Table Closing [Text Block]

rr_PerformanceTableClosingTextBlock

The S&P 500® Index is a free-float market capitalization-weighted index of 500 of the largest U.S. companies. The Dow Jones Global Moderate Portfolio Index is a benchmark that takes 60% of the risk of the global securities market. It is a total returns index that is a time-varying weighted average of stocks, bonds, and cash. The Index is the efficient allocation of stocks, bonds, and cash in a portfolio with 60% of the risk of the Dow Jones Aggressive Portfolio Index. The indexes are calculated on a total return basis with dividends reinvested. The indexes are unmanaged and not available for direct investment.

After-tax returns are calculated using the historical highest individual federal marginal income tax rates and do not reflect the impact of state and local taxes. After-tax returns are shown only for Class A Shares; after-tax returns for other classes will vary. Actual after-tax returns depend on the investor’s tax situation and may differ from those shown. After-tax returns are not relevant to investors who hold fund shares in tax-deferred accounts or to shares held by non-taxable entities. In certain cases, the Return After Taxes on Distributions and Sale of Fund Shares for a period may be higher than other return figures for the same period. This will occur when a capital loss is realized upon the sale of fund shares and provides an assumed tax benefit that increases the return.
