<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.>
Yuki,
You are handling it like a Pro.
Debugging is a big challange, and while the new Portfolio modes were
sorely needed, they also compound some of the aspects of debugging
because of the position adjustments that are made under varying losing
conditions. AB can now play some REAL headgames with us <g>.
