I am building an EA for MT4 and I have the following problem. When I run it on a platform with only the .ex4 file is available, I have divide by zero error (on a line where I get the price of another pair to convert the lot size for proper risk management). When the source file is available in the Experts folder, everything is working fine.
I have tried recompiling and reinstalling the expert and event mt4. The problem persists.
