people, is there a virtual dedicated server anywhere on the internet for free?
No.

Guys who are friendly with Pyatra. Look at my Indy for the championship, please. I'm stuck - I can't decide...

Translating from 4 to 5 - there on the forum - silence. Put the code in the branch - on this page. Description - on the previous one.

Thanks.

thanks, what is digits?

The digits of a trading instrument - how many digits after the decimal point it has.

Significance of a trade instrument - how many digits after the decimal point it has.

That is, if I know the digits are 4, then the code can be shortened like this?

int dg = 4;

............ code

if (OrderSelect(j, SELECT_BY_POS, MODE_HISTORY)) {

ocp=NormalizeDouble(OrderClosePrice(), dg);// normalize order closing price
otp=NormalizeDouble(OrderTakeProfit(), dg);// normalize order TakeProfit price
if (ocp==otp) return(True);
}

return(False);

}

I don't know if it's possible - according to the author's idea (well, it seems to me) this part of the code is designed to automatically determine digits - so that the code can determine exactly how many digits after the decimal point to round prices to. Only this part of the code is uselessly made.
Can you please tell me if there is an indicator that calculates the total number of open orders for all pairs involved in the trading process?

Nope, no. It is easier to make a simple Expert Advisor which calculates the number of open positions.
