| Performance Narrative [Text Block] | The following bar chart and table illustrate the risks of investing in the Fund. The bar chart provides some indication of the risks of investing in the Fund by showing changes in the Fund’s performance from year to year and the annual total returns of the Fund’s Investor Class shares. The table provides some indication of the risks of investing in the Fund by showing how the Fund’s Investor Class returns, both before and after taxes, and the Fund’s Institutional Class returns, before taxes, averaged over certain periods of time, compare to the performance of a broad-based securities market index, the S&P 500® Index, during the same periods. In addition, the performance of the Bloomberg US Treasury Bills: 1-3 Months Index and a composite index are provided. The other securities market index shows how the Fund’s performance compares with the returns of other securities market indexes that reflect market sectors in which the Fund invests, during the same periods. The Defensive Market Strategies Fund (DMSF) Composite Index shows how the Fund’s performance compares with the returns of an index constructed by the Adviser as a composite of the two securities market indexes to reflect the market sectors in which the Fund invests, during the same periods.The Fund’s past performance (before and after taxes) is not necessarily an indication of how the Fund will perform in the future.
