What is the purpose of if(!IsTesting())

New comment
 

I hired someone to build an EA and then it performs as per the logic the in strategy tester but sometimes not works same way in the DEMO. I have a doubt in following codes and I don't know why he needs to define "testing" especially since it should work same in testing, demo and real. Please, can anyone help me to understand this?

The EA doesn't work in the same way like it works in testing mode. Missing many opportunities in the demo. I want to know that is because of the coding. Specially what is the purpose of having this "

The attached code does not contain anything suspicious in regard to IsTesting() function. If you observe differences only sometimes, you need to find another reason for this. If conditions with IsTesting could negatively affect trading in the tester, then it would happen regularly.
