Partial Exit With Mt4

I start trading with a demo account using MT4 plateform but i can't manage to place differed order that will close partially my position. I can do it manually by changing the size of my order before I clic on the "close position" button but I can't do it with a differed order, it always open a new position instead of close partially the current one.

Can somebody help me, thanks.

That's how it works.

Perhaps you are used to a platform that does not allow hedging. I have used non-hedging platforms where opening a new trade would subtract the value of the new trade from an existing trade in the opposite direction. MT4 allows buy and sell trades to be open concurrently.

I get it, thank you. So I must use an EA for partial exit.
