Thanks to Reader Randy H. for suggesting this one. In his article “The Quest For Reliable Crossovers” (Stocks & Commodities Magazine, May 2008) author Sylvain Vervoort sets forth a trading method using the crosses of two unique moving averages. Specifically, he used a zero-lag triple exponential moving average of 1) the typical price (h+l+c)/3 and 2) the Heikin-Ashi close. He successfully backtested his method on 211 stocks and found using a 55 period average on daily charts was optimal.
