| Factors Affecting Performance [Text Block] | How did the Fund perform in the last year? During the Fund’s fiscal year that ended July 31, 2024, the S&P 500 increased 22.15% while volatility dropped 48.33% (measured by the SPVIXSTR Index, an index that measures the result of long exposure to VIX Index futures). For the year, the Fund gained 7.01%. There were several interruptions in the trend toward higher equity prices during the year, notably around October and November of 2023 and again in April and July of 2024. In response to these initial moves lower in equities, which were accompanied by jumps in volatility, the Fund’s volatility trend-following model utilized a modestly larger allocation to volatility, in preparation for the possibility of a large upward trend. However, markets quickly turned around – lower in volatility and higher in equities – without ever realizing a large trend higher in volatility. Turning points are generally unfavorable market conditions for a trend-following model, as the model prepared to capture possible large uptrends in volatility assets that did not materialize. The model did, however, shift its allocations back out of the modestly higher exposure to volatility assets rather quickly. The Fund enjoyed gains for the year, preserving positive performance during what was generally a bull market with low volatility. | ||||||

| Factors Affecting Performance [Text Block] | How did the Fund perform in the last year? During the Fund’s fiscal year that ended July 31, 2024, the S&P 500 increased 22.15% while volatility dropped 48.33% (measured by the SPVIXSTR Index, an index that measures the result of long exposure to VIX Index futures), and long-dated US Treasuries were down 1.41% (measured by the LT11TRUU Index, an index which measures the result of exposure to 20+ year US Treasuries). For the year, the Fund gained 11.80%. There were several interruptions in the trend toward higher equity prices during the year, notably around October and November of 2023 and again in April and July of 2024. In response to these initial moves lower in equities, which were accompanied by jumps in volatility, the trend-following aspects of the Fund’s models utilized a modestly larger long allocation to volatility, in preparation for the possibility of a large upward trend. However, markets quickly turned around – lower in volatility and higher in equities – without ever realizing a large trend higher in volatility. Turning points are generally unfavorable market conditions for a trend-following model, as the model prepared for possible large uptrends in volatility assets that did not materialize. The model did, however, shift its allocations back out of the modestly higher long exposure to volatility assets rather quickly. Furthermore, the mean reversion aspects of the Adviser’s short volatility model mitigated some of the effect of these turning points and contributed to increased Fund returns, as compared to a portfolio managed entirely according to the long volatility model. As a result, the Fund enjoyed gains for the year, delivering on the objective of long-term capital appreciation. | ||||||
