Beginner's question: Is MQL4 only for MT4 and MQL5 only for MT5?

 

Hi:

I am using MT4. I need to write an custom EA. When compiling, I received the following error: MQL5 files compilation is not supported, syntax checking only.

Is compiling MQL5 not supported in MT4?

only

Hello. MQL5 works with MT5 only.  MQL4 works with MT4 only.
