Can one EA give two differents results for two different people?

 

I sold one of my EAs to a client. He is getting false signals that I am not getting, and I am getting the correct signals.

We are both using the same exact EA and the same exact broker . The EA is attached to the same exact pairs.


What could be the cause of this?

 
If you are doing this for cash you should be able to resolve issues like this yourself . . .
 

Setting. different server connection. just to name a few
