what timer and what looping?

  {
//--- create timer
   EventSetMillisecondTimer(500);

    Print(

      ";   lparam = ", lparam,
      ";   dparam = ", dparam,

  }

By the way, OnChartEvent() works too, in particular onMouseMove and onClick.

I re-created and compiled the code - everything is fine.

[Aliaksandr Yemialyanau]

After starting the Expert Advisor in the tester, the terminal window closes.

The reason is in this line ( function OnInit() ):

if(Bars<250) {Alert("ERROR HISTORY BARS<250"); return(INIT_FAILED);}

After launching on the chart, the Expert Advisor generates error"ERROR HISTORY BARS<250".

Print(Bars);

It shows 0. There are 16387 bars in the window.

Fonts like Wingdings have gone missing in graphical applications. The new MT4 must be unicode... But that's just in the heat of the moment. Perhaps the problem is something else.

I cannot understand why this code returns 00 00 00 00

string TimeS(string txt)
{
string d,h,m,s,n; 
d=DoubleToStr(Day()    ,0); if (StringLen(d)<2) d="0"+d;
h=DoubleToStr(Hour()   ,0); if (StringLen(h)<2) h="0"+h;
m=DoubleToStr(Minute() ,0); if (StringLen(m)<2) m="0"+m;
s=DoubleToStr(Seconds(),0); if (StringLen(s)<2) s="0"+s;
if (StringLen(txt)==6)
n =txt+d+" "+h+"."+m+"."+s+" ";
else
n =txt+d+" "+h+":"+m+":"+s+" ";
return(n);
}

Yes, we will fix this error - there will be an update tomorrow.

Try using a more compact construction in each line that converts a number to a string for starters:

d = LeadZero(Day());

string LeadZero(int value)
{
   if (value > 9)
      return (DoubleToStr(value, 0));

   return ("0" + DoubleToStr(value, 0));
}

[Renat Fatkhullin]

To ensure that updates to other terminals are not affected, simply delete the directory C:\ProgramData\MetaQuotes\WebInstall after successfully updating a test terminal.

Even like this

Comment(Day());
