Seeing OP_SELLSTOP order send failed with error(3): invalid trade parameters in the log on GP ...
As the previous log entry says: Placing Sell Stop for 8.120000000000001 of AUDCAD at 0.00000 I assume two things (can't fix myself, no source...):
1. NormalizeDouble for lot size calculation missing - maybe
2. Something wrong for the stop stop calculation
Btw. I'm using ALR_AutoTPandSL set to TRUE (which obviously is the reason, because setting to false calculates the SL/TP correctly). I'm not sure if the automatic calculation isn't done yet or needs some fixing (if you want me to look into it, just drop me a note)
Cheers,
Andy
