Two moving averages are plotted against a market index price to signal long term market trends. To avoid whipsaws, when applied to the S&P 500, the 40 week moving average is given a negative 3.6% filter and the 25 week moving average is given a positive 2% filter. Crossings of the moving averages are ignored. An index price dipping below the negative 3.6% filter of the 40 week moving average will generate a sell signal and an index price rising above the 2% filter over the 25 week moving average will generate a buy signal. A related moving average fund buys and sells financial instruments based upon the methods of disclosed system, know as Winans Trend Indicator.
