How do I open a position at a precise time? For example, I need to open a position at 00.15 local time.

if (hour == 0 && minute==15) {then do this;}

Look into Expert Advisor, there are some missing (and some unnecessary) brackets:

Damn bot doesn't allow to lay out all code, I'll have to cut it. I cut switch() to make it fit.

How would I write all available history to a file in the form of these lines

O;H;L;C;volume;MA3;MA5;MA7;MA13; ... and other indicators further

On H1 timeframe?

Thank you

This is a user-defined subroutine that adds a text line to the end of the file. It is placed after the start function. At the very start we use it as follows:

 // --------- Генерируем имя файла ------------
  FileName=Symbol()+"_"+DoubleToStr(Day(),0)+"_"+DoubleToStr(Month(),0)+"_"+DoubleToStr(Year(),0)+".txt";
  TextInFile=TimeToStr(TimeCurrent(), TIME_DATE| TIME_SECONDS);
  TextInFile= TextInFile+" "+DoubleToStr(Bid,Digits);

Thank you!

Can you also tell me how to arrange to go through all the history?

I have a file that contains H1 data from 1999 to 2009

Planning to install a new operating system purely for the tester, who knows which OS has faster tests?

Good evening.

Just yesterday I tried MQL5 for the first time. I have a problem with the button. Please advise how to set coordinates of a button, change its colour, set text and how to receive feedback from it. I have tried to use the old version that was published before the MT5 release. Where can I read it? Thank you. :)

Questions from Beginners MQL5 Can I use old Any rookie question, so
