How to program indicator to change background color?

August 26th, 2015, 08:10 AM

Hi guys,

I am trying to program an indicator to change background color when some conditions are met.

I thought this is done straight forward with PlotAttributes constructor, but I can't see the change of background color at all. Could you help?

Code

Plot1 = AddPlot(new PlotAttributes("", EPlotShapes.LeftTick, Color.Blue,Color.LightBlue,1,EPlotStyle.Solid,false));

Background colour changes set by `PlotAttributes()` only affect the background of cells in the Scanner/Watchlist window. For indicators added to charts this value is discarded.

There's a tutorial on `PlotAttributes` here: Setting plot options programmatically in [AUTOLINK]MultiCharts[/AUTOLINK] .NET: a closer look at PlotAttributes | TradingCode.net

Thanks. So is changing background color of the chart possible in MC?

Like in below chart in NT, I used different color to represent different "state" of the market.

That's not possible no, and certainly not possible like it is in NT.

You could do a workaround where you draw a bunch of plots, all with the same colour, to make it look like there's another background colour. But that's a lot of coding work and will very likely negatively impact the performance of your script. So a hack, nothing more.

Yes, you can do that nicely in MC.NET, too. You will have to use GDI for that, though.

Never looked into that yet. Do you have a code example/snippet for that?

For NinjaTrader? For NT, it is the "BackColorAllSeries"

Example:

Code

			if(_CBBP_Signal_up>=1)	BackColorAllSeries[0]=Color.LightGoldenrodYellow;
			if(_CBBP_Signal_down>=1)	BackColorAllSeries[0]=Color.LightBlue;

Thanks for the reply. Could you share more tips/samples on how to do it? I read this page but didn't get how to do it still.
