Convert an EA from mql4 to mql5

This is a 2000 lines own-made breakout EA that I need to have cleanly converted from mql4 to mql5 for learning purposes

The start() is about 400 lines long ; basic breakout with specific features , built for Index CFDs with 2 digits (typically DAX or SP500; TP SL... are expressed in actual Points)

The Ontester() is about 400 lines (contains 58 different custom opimizations)

The Deinit() is about 150 lines

The remaining are functions mainly called from the Ontester() and Deinit()

I will provide the .mq4 file

To fulfill the job, you need to provide me the .mq5 file that has no compilation mistake and is operationnal like the original (basically your .mq5 EA has to provide the same deals using the same parameters and data set in MT5 than the .mq4 EA in MT4 ), clean code, well written and documented if necessary in addition to repeating the comments I put inside the .mq4.

You shouldn't recreate the ea from scratch but when possible, use the same logic I did (even if imperfect) , so I can understand the way to convert. If impossible to use the same logic, please explain.

I can provide the .mq4 , a parameter .set file for the test, and a DAX TickData set on demand to those interested by this Order
