Copy service between MT4 accounts with special feature

Hello,

I have a simple MACD expert advisor running on a demo account, and I need a copy service to another MT4 account but in this way:

1) The EA on demo (Called Principal) when close a position in profit, will open a new position in the opposite direction

2) AT THIS STAGE, that trade must open a reverse position on the second account (called CLIENT)

Example:

at 10:18 the ea on PRINCIPAL account closed a BUY trade on EUR/USD with $100 profit. At 10:18:10 seconds on this account, the EA opens an opposite position (SELL)

At the same time, the trade must be copied in reverse mode (BUY) on the client account and will be closed when the other position on main account will be closed

This is the file to modify.  Make a prototype  and only after I have verified that the work has been made correctly I will select you as final developer. NOT BEFORE.
