Hi.
I had this problem fixed just yesterday. The problem was triggered by
the following line:
PositionSize = (pct_equity * -1) * (BuyPrice / Stop);
(As you can see, I use fixed percent risk model.)
Notice that depending on the value of the Stop variable, the formula
above can generate large PositionSizes, i.e. values much less that -100.
So the fix was simple:
PositionSize = Max(-100, (pct_equity * -1) * (BuyPrice / Stop));
The problem manifested itself on CBT when doing some math using
sig.PosSize, *even if I range-check the variables in the CBT proc*.
Also, the popup didn't appear if I temporarily commented out the CBT
proc, even without the fix above.
To me, it looks like this problem is CBT-related, *BUT* I suggest you to
check all your AFL code for range problems.
Hope it helps.
