I'm trying to use this feature, but I can't seem to get it to take pictures of indicators on the chart.

Is it even possible? Documentation doesn't mention anything about the chart's indicators.

RR, I wrote one in this thread. It captured the Fractal indicator as well as the EA smiley face, so I don't know why it wouldn't capture other indicators. The market is closed so I can't test it.

My understanding is that is an image bit capture so it wouldn't know what's on the screen.

Would it make a difference if the indis were attached to the chart during a backtest?

[Edit]: It doesn't seem to capture the indicators. Looks like it will only use standard indicators, not custom ones.

Here you go, guys.
I did this long ago.
A++;
DoubleToStr(A,0);
WindowScreenShot("shots\"+A+".gif",640,480);
StrToDouble("A");
Comment(TimeToStr(TimeLocal()));

Hey Market Pips,

Doesn't seem to work for me. I'm trying to take screenshots of the chart as a trade is taken (custom indis, objects and standard indis included).

So far, I can see standard indis, and chart objects, but no custom indis.

Hi Ronald Raygun. Here is my screenshot made by WindowScreenShot() function.

MQL4 code:
PHP Code
if(!WindowScreenShot(StringConcatenate(Symbol(),"_",Period(),"_",TimeToStr(TimeCurrent(),TIME_DATE),"_",Hour(),".",Minute(),".gif"),1280,1024)) Print(GetLastError());
Screenshots will be placed into $TerminalPath$-experts-files folder.

This is the indicator I'm trying to get windowscreenshot to capture.

See if you can do it. I'm having trouble getting the function to work.

Sorry, I meant for backtesting.

I currently have the EA take a snapshot after a successful trade. Problem is I can't see the line.

Hi Ron,
I've coded a simple EA to take screenshot, it works.
here the ea code:
PHP Code
int start()
  {
    if(ObjectFind("shot")>=0)
    {
      if(!WindowScreenShot("shot.gif",640,480))
        Print("Screenshot failed");
      else
        Print("Screenshot succeeded");      
      ObjectDelete("shot");
    }
   return(0);
  }
Run this EA, put any indicator on chart. put arbitrary object, named it "shot" (without double quotes). screenshot will be taken and saved on testerfiles. Check this folders, there should be a file named "shot.gif".

I'm almost definitely missing something.

Here are two pictures of what windowscreenshot sees, and what I see.

Code included as well, why are the two pictures different?

I have found something interesting in documentation:
Inserted Code
The execution of iCustom() does not require the attachment of a corresponding indicator to a security window. As well as the call of iCustom() from any application program does not result in the attachment of a corresponding indicator to a security window.
I tryed to solve this problem for a few hours but unfortunaly I haven't found solution. Its iCustom() issue.
