I can not say you by codes (I don't know) but we did the same with SilverTrend EA in elite section. Because this EA reduced deposit to almost zero for 3 weeks trading 0.1 lot (from 25,000 to 5,000 for 3 or 4 weeks by 0.1 lot size if I remember). So we were thinging that this reversal will help. Nothing.
It was the same.
I think it is the subject to ask and bid price also (for sell and buy orders).

I think that EA should be too bad to do it but Firebird is too bad sometimes and sometimes is too good.
