Thank you very much for this!!!

Thank you for "thank you" :))

But I strongly recommend using the MQL5 version, since it is 10 times faster. And for graphics it is very significant.

Yes, of course, but it’s very sad to realize that your program runs 10 times slower from the potential.

I'm using 1.45 release.

I used it inside a custom indicator I wrote. It does work fine if I use the custom indicator directly over a real time graph or if I backtest the custom indicator with the option "custom indicator" specifically.

But if I call my custom indicator inside a EA and I try to use this EA on a real time graph or inside the Tester I got the error:

"array out of range in 'iCanvas.mqh' (222,30)" on a real time graph

or

"array out of range in 'iCanvas.mqh' (507,21)" trying to backtest the EA in the Tester.

Inside the indicator I called

int _subW = W.SubWin;  //at the beginning of a onChartEvent "if (id==CHARTEVENT_MOUSE_MOVE || id ==CHARTEVENT_CHART_CHANGE)..."

and at the end of the routine

Canvas.Update();

I use MT4.

Any help would be appreciated. Thanks.
