I did figure out one problem: The back tester was ignoring some
losers in the modified code that it was showing in the original code.
The problem was rather simple once it got through to my slow brain:
When you have ALL losing trades, which is what I am trying to
isolate, your equity drops in a big hurry and you can't take the
positions you once could. ^_^ I am still not satisfied with the
results though, but I'll try some more.
