help in implementation of hedge code

[Jefferson4990]

First apologize for my bad English.

I am new in MQL4 programming and also in the forum and searched and found nothing like what I want. First, my code sends two orders , in opposite directions, and I need a code to open a new order so that one of them is closed.
The order must always be opposed to pendende order. So always have an open BUY and SELL order. When SELL order closing , opens a BUY and vice versa.
If anyone can help me describing the code I'll be very grateful. Sorry for the ignorance , I am beginner in programming. Thanks!
