Long Only or Short Only

[Dua Yong Rew]

MT4 offers this setting when attaching the EA to the chart to have Long only or Short only

I cannot find this in MT5. How can I do this in MT5? The only thing I can think of is to program into the EA.

[Dua Yong Rew]

anyone?

I haven't seen that option in mt5 strategy tester, therefore I'm inclined to say it isn't there. I've used that option maybe twice within mt4, most time, if I want buy_only, I just place op_buy in the ordersend function.

I would suggest extending the CExpert class and changing the CheckOpen method in order to only check long / short according to a parameter

How is this related to the topic ?

It's a simple way to implement long only / short only EAs, since the option doesn't seem to be available in mql5 (did I misunderstand the question?)

so meaning is confirmed that MT5 do not have this option.

I think I have to declare a custom enum as an input?

where can I read on custom enum?

I don't think have any problem with mql5. Of course with mql5 you can send any order you want. He is talking about an option of MT4 terminal which disappears in MT5 terminal. With this option you can have a EA placing only Buy order for example, even if the EA is build to send buy and sell order.

I will try to upload the modified version to the code base

 That's what I was talking about, a way to modify the default implementation in order to provide that option

It's absolutely not the same thing. With MT5, each EA has to implement his own method to buy only or sell only. Of course you can provide your own implementation by extending standard class.
