Hi, I found this interesting indicator for MT4 called by his author HAC, Hurst Average Composite.
According to him, we have four moving averages involved here. The base one is the cycle period displaced forward by half its length. The other three are 1/3 the base, 1/2 the base and 2x the base, all projected 1/2 their lengths forward. Again, these are dynamically adjusted according to the current market cycles. The next component was to average the four MA’s, and the cycle is calculated using John Ehler’s formula.
