This article is a quick guide to MQL4 language functions, it will help you to migrate your programs from MQL4 to MQL5. For each MQL4 function (except trading functions) the description and MQL5 implementation are presented, it allows you to reduce the conversion time significantly. For convenience, the MQL4 functions are divided into groups, similar to MQL4 Reference.

Yes, I know.
Two different versions are downloaded to suit each MT and used, which I have done ok before.
Just don't why this giving me this outcome.
The EA makes trades on a 15min time frame.
I have downloaded the data in 1min time frames and seems to have solved the problem.
I will just have to make a phone call tomorrow to clarify that the outcome is dependable.

The EA is optimizing OK in the MT4 version but not working in the MT5 version.
This is what it is telling me.
