Does anyone know what is this error & how to fix it? EURUSD,H1: Error: 0 & GBPUSD,H1: Error: 0

 

Hello everyone,

I'm TC, a newbie here.

I am currently trying out an EA called XM V2.5 on Exness MT4 real cent account.
When I used this EA on MT4 demo standard account, it worked fine. But on real cent account, it doesn't open any trades and give these errors on 2 charts:

EURUSD,H1: Error: 0

GBPUSD,H1: Error: 0

Anyone knows what this is and how to fix it?

Thank you for your advice.

 
Error zero is no error. The code is broken. Don't look at GLE/LE unless you have an error. Don't just silence the compiler (MT5/MT4+strict), it is trying to help you.
