Then does it miss some of the stops, orders and profits?

sergeev:

If you want an array to be filled in the function, pass in a reference

if you just want the first element to be returned

then

Cool))

Thanks for the answer!

If I pass by reference, then there's nothing to return, the array will already be changed, right?))

Is there any way to return a pointer to the array?

Thanks for the reply!

No. Everything is triggered, but after the opening of a new bar. check it yourself in visual mode

Vitaly, write me in your personal message what was the reason for the fact that the optimization was not going beyond some MA parameters - Vinin suggested the solution - there was something about the number of bars on the history, some kind of additional testing ... It doesn't take much in a nutshell ... I understand, I haven't encountered it myself, but I don't know...

If the average loss per trade is more than 2 spreads, it works on any EA. PAUKAS suggested this.

I have applied this tip to this case:

Doesn't the advice.... work? It still ends up being a loss, after all.

You make another normal buffer and process it with a dash.

Good day!
Can someone advise how to make an EA indicate (write) on the terminal screen
which set of input parameters is currently loaded. (for example - proba.set )
