Ordersend error 131 how to fix it

Hi I wrote an EA to test part of a strategy but while backtesting it I get a Ordersend error 131. I have changed my lotsize to 0.1 and then it works fine but when I change to a lotsize of 0.01 it gives me the error. My brokrer allows 0.01 lotsize trading. If I trade manualy there is no problem with trading 0.01 lot sizes.

I wil post the code here. If anyone could please help me fine the problem I would be very greatfull.

It works OK for me
