My EA is not expert and cannot be executed - page 2

 
Keith Watford:

OnStart() is for scripts

OnTick() is for EAs

Thanks a lot , It works I'll update all my EAs so I can run it with last update of MT4. But now I need to try to correct all errors happen when I put strict property with the EA.

Regards

 
if I make a set file for an EA and then I change the varible from extern to internal ones and I made an .ex4  file.. if I run the set file does it will make the same effect after this changes?
