Trade copier in the same terminal

can anybody  make ea that similiar with trade/OP copier?

but i need a trade multiplier..the trigger: EA will open one new position with 10% -500% multiplier everytime trader or signal open a position..but the EA will not triggered by its own trade (of course because it can be infinity trade until no margin at all lol ) and i need the mq4 file.

the copy trade done on same account/ terminal, just after the trade is open..the same when the trade is close,,so 1 trade open manually/by signal will trigger 1 more trade automaticly by EA. and the 2nd 3rd or 4rd trade opened manually/by signal while the previous one not close yet also become trigger.

actually the idea is to raise the profit by subscribing low risk signal
