Global variables in EA

 

Hi, 

 I have written an EA and is running on 2 seperate charts GBP/USD and EURUSD, I assume that there will be 2 seperate instances of the EA running and that both do not share the same variables , global variables included.

One instance running on GBPUSD does not affect the one on EURUSD.

Any comments on this please. Thanks. 

 
Correct.
 
Correct, if they are only EA global scope.

If they are terminal global scope then they would overwrite each other.
