Changing plot color to an existing plotted plot

[KhaosTrader]

Hi,

In my indicator, i paint a plot, then later I want to change the color of the plot that already has been painted. Somehow when I just write the plot value and with the new color by just calling the funciton, the old color still remains. Is there something I need to do to allow the color to change?

to best clarify, here is some code, that fires each tick....

			  if (SetupActive)
				  {
					  PlotBrushes[(int) enuPlotList.TrailingStop_Long_Inner][0] = Color_TrailingStop_TradeActive;
				  }
				  else
				  {
					  PlotBrushes[(int) enuPlotList.TrailingStop_Long_Inner][0] = Color_TrailingStop_TradeNotActive;
				  }

So, initially, when the setup occurs, the trade is not active, so it will paint with TrailingStop_NotActive Color, but if it becomes active intrabar, then the color will change to TrailingActive_Color. Since this fires every tick, I assumed that it would just redraw the plot and hence change the color, but it doesnt seem to.

Thanks in advance for your help.

Hello KhaosTrader, and thank you for your question.

The attached indicator behaves the way you described, in that intra-bar, the current bar's plot will alternate between two colors. You will notice previous bar's plots will alternate between the two colors I have selected. I am including a screenshot from my system. I believe studying this code and its behavior should answer any questions you have about PlotBrushes, but if not, or if there is anything else we can help with, please do not hesitate to reach out and we will be happy to assist further.

Ok, I have a question about plot colors. If the default plot color is transparent, and for a given bar, i change it to a color (say yellow), and then on the next bar i dont set the color, is the color back to default transparent on the next bar?

Hello again KhaosTrader,

As you will be able to verify with the script I provided, the default color value for new bars is going to be the one you set up in your Initialize routine when you create the plot. I would recommend, then, creating your plot via


AddPlot(Brushes.Transparent, "Plot Name");

Please let us know if there are any other ways we can help.
