You're the one who took 24 hours.

ZS. And you're the one who removed yourself...

I saw right away that I missed it. And I saw that you beat me to it, so I didn't bother you.

Date-3*PeriodSeconds(PERIOD_D1);
Outputs ten-digit numbers, not the date

Print("TimeCurrent=",TimeToString(TimeCurrent()),", TimeCurrent-three days=",TimeToString(TimeCurrent()-3*PeriodSeconds(PERIOD_D1)));


 
How can I see the source code/libraries of functions that come with MQL4? I'd like to look at their properties and make similar or better, who knows what on this subject?

There is code to output text from a link!!!

    }
}

string httpGET(string strUrl)

   int handler = hSession(false);
   int response = InternetOpenUrlW(handler, strUrl);
   if (response == 0) 
        return(false);
        
   uchar ch[100]; string toStr=""; int dwBytes, h=-1;

Through this code I output text which is updated a couple of times every day! But this code takes the text once and does not update it anymore! The update occurs only when you reload the terminal!!! Is there any way to add to the code to update the displayed string?

Call this code when you need to update the text.

It doesn't work! Even if you uninstall the owl from the chart and put it back, the old text remains, not the updated ...... Only restarting the terminal helps(((

Where in the EA/indicator do you call this code?

and where "return false" - add Print
