Old post....but that's ok.
I was able to recreate a similar system using moving average envelopes (Envelopes) 10 period moving averages, 2.0 is the deviation on the 1 Day Chart.
Also I used 10 period MAs, 1.0 deviation on a 1 hour chart. I like this one the best.
It seems to catch the extremes in the data or very close to them. Then the trend reverses and goes to the mean. I believe this is called Mean Revision.
A strategy might be a 40 pip tp and a 15 pip sl. (for the 1 H chart).
Are there any programmers out there who would be kind enough to code this so myself and others can test it?
