As you can see in the image some trades are succesfull and some are not.

I use MT5 from metaquotes where i have opened a demo account and trying to test my strategy.

Can you spot what i am doing wrong?


I Tried.

1 to check filling mode first.

2 to normalize price ask/bid.

3 to remove request.sl and request.tp
