Mql4 does not have handles, positions, or CopyBuffer. It must be rewritten.

I will repeat what William wrote—MT4 does not have positions.

It only has orders, be they market orders or pending orders. It does not have positions (nor deals), only orders.

Please read the documentation ... Trade Functions - MQL4 Reference

EDIT: Also, MQL4 does not have a "Trade" Standard Library.
