ERROR

 

I have trade for 0.1 doller and meta trader set the trade 3.0 doller 

this is the problem in meta trader 4 

 

Metatrader can not set the trade by 3 lot if you open the trade by 0.1 lot.

Seems, you are using EA (bad coded EA), or you subscribed to the signals with lot size calculated in automatic way.

Reason:
