Некоторые ДЦ на реальных счетах именам символов присваивают всякие префиксы типа "." или "FXF".

Как мне подставлять эти префиксы?

Try string StringConcatenate(...)

Got it, I'll do it...

Also, the condition doesn't work.

It doesn't "don't work", it just doesn't get there for the same reason as for X

This can be clearly seen by the fact that there are no signals from i in Alert

it does not "not work", it just does not get to it for the same reason as X

this can be clearly seen by the fact that there are no signals from i in Alert


Yes, that's right...
 
Hooray, i says!!!!!!

ilunga:

well the "on the fly" option worked:

Yes, that's how it works. Thank you!
 
Phew!!! Hooray!!! We did it!!! All right!!!
 

Good afternoon. This is a problem, the Expert Advisor I wrote hangs after a certain amount of time? When I uninstall it, it says shutdown by timeout. What is the reason for this?

Remove the while loop, it is superfluous.
 
Thank you very much. Another question, I have 15 min. timeframe, let's say an order was closed at 18-38-55 how should I make my EA not work till 18-45-00, i.e. till the next bar?
 
Look at https://www.mql5.com/ru/forum/133552 and see how the Timebar variable is implemented in your case (with some modifications).
