the ea is copier, I want add  a function is reverse copier.

How to control?

My computer open two MT4.

Two MT4 is master and slave.

Slave copy master trading order.

part1:
the EA copy times is 2 second above, I want copy time is 1 second.

part2:
Add a usage deadline in the code, for example, the expiration date is 2022/12/31.

part3:
Because the prefix and suffix cannot be copied, for example, EURUSD.a cannot copy to EURUSDm.

part4:
MODE1 Just convert COPY SELL to BUY, without COPY SL and TP.
MODE2 Just swap SL and TP.
MODE3 Calculate the gap between SL and TP.
MODE4 Convert COPY buy stop/buy limit to sell. Convert COPY sell stop/buy limit to buy.
