Error 131 on EA Robot
Brokers have 3 values for lot size.
MarketInfo( Symbol(), MODE_LOTSTEP ) // IBFX mini 0.01 MarketInfo( Symbol(), MODE_MAXLOT ) // IBFX mini 50 MarketInfo( Symbol(), MODE_MINLOT ) // IBFX mini 0.1
Your running on a non-mini count so lotstep is most likely 0.1 therefor 1.00 is ok and 1.10 is ok but 1.01 is not.

I'm an ex-option trader who has started playing around with forex and am trialing one of the latest EA Robots. After operating very effectively for the first day, every order the robot tries to place is rejected with the Error 131 - invalid trade volume lots 1.02. I have researched this on the forum and have attempted to adjust the trade volumes etc to no avail. I have contacted the manufacturers but they take 2-3 days to reply and have as yet been of little help. The biggest question is why did it trade properly for one day then go into defaulyt mode? Can anyone help???
