| Expenses [Text Block] | What were the Fund’s costs for the last six months? (based on a hypothetical $10,000 investment) Class Name Costs of a $10,000 investment Costs paid as a percentage of a $10,000 investment Advisor $139 2.79% |

| Factors Affecting Performance [Text Block] | How did the Fund perform during the reporting period? The Fund earned a positive return of 0.82% for the six months ended June 30, 2024, in spite of often difficult debt market conditions. The Bloomberg U.S. Treasury Bills 1-3 Months Index, the Fund’s primary benchmark, was up 2.68% for the same period. Strategy The Fund seeks total return while keeping the Fund’s volatility and downside risk below that of major equity market indices. Techniques The Fund started the year fully invested in low volatility bond and income funds and preferred stock funds. Treasury yields were falling as the markets widely anticipated that the Federal Reserve would lower interest rates. When inflation began to come down at a slower pace and the Fed dampened the outlook for a March start to interest rate cuts, yields turned up, small caps turned down, the uptrend in high yield bonds slowed, and the S&P Index briefly paused. The current stock market environment is positive, but volatility has increased over the past few months resulting in challenging market conditions. The sub-advisor believes that chasing a handful of stocks in a narrowing market advance is not prudent, but the sub-advisor also believes that better times are ahead. Anticipation of the first interest rate cut should provide a tailwind for bonds, particularly interest sensitive bond groups. The Fund’s holdings have not changed significantly since the beginning of the year, as the Fund continues to maintain positions in bond and income mutual funds, preferred stock funds and a limited exposure to stocks. The sub-advisor looks forward to taking a more aggressive posture when warranted by market conditions. |
