Changing EA (simple question)

 

Hello all. I'm new to MT4 and programming. I'm trying to learn!

Simple question: Every time you change an EA do you have to restart the MT4 platform to take effect?

Thanks

 
Probably not, but I do just to be sure.
 

On a live chart you get REASON_RECOMPILE

In the tester it is ignored.

you do not have to restart the terminal.
