Ordermodify error 1 From an EA I downloaded

New comment

hi


The following code whenever I back test it I keep getting an ordermodify error 1 but I don't know where in the source code to change it so I can put it right. Please if anyone can help me with this I would appreciate it.

You'll get an " ordermodify error 1" if you try to modify an order with the same values. So nothing was changed. To resolve the error test if at least one value was changed before executing the modify function.
