Platform issue

Yerim Rayann Gon Diarra  
Hi, I coded an EA that work perfectly fine on my Platform but not on my friend Platform.

The Platform have the same version and built. 
The source code doesn't include or import anything. 

Just pure MQL4 code. 

But can figure out why the isn't working properly on my friend Platform. 

Do you have an idea?

Use the debugger or print out your variables, including _LastError and prices and find out why. Do you really expect us to debug your (hidden) code for you?
