Traders and coders are coding for free:

• if it is interesting for them personally, or
  
• if it is interesting for many members of this forum.

Freelance section   of the forum should be used in most of the cases.

Hi

You cannot define those mt4 functions in mt5 and use them later. I assume you use those functions somewhere in the code to trade or manage positions and trades, but it’s not allowed in mql5.

You need to use proper classes and functions from the library you included like: CPositionInfo and methods for it: SelectByIndex, Symbol, Volume, PositionType etc.

Have a nice day👍📊
