I don't know anything about the 2652 method, but looking at the one link it looks to me like the stops are set as follows....If I am reading this wrong correct me.

Stop loss 1%
Stop profit .5%

This doesn't look like a very good formula for success. Ignoring trading costs(for simplicity's sake), the trade would have to go your way 67% of the time for you just to break even. At the point you are right 67% of the time, you should be making a profit.
