    Changing Plot Color Dynamically

    I'm trying to creat an indicator where the color of the plot changes according to logic in OnUpdate(). I've tried making the plots pen local to the strategy and changing its color in OnUpdate() but that doesn't seem to work. I'm pretty sure i've seen other people do something similar but i can't seem to find any examples now that i'm looking for them. Any ideas on how i can go about doing this or examples of something similar?

    TIA

    Hi darckeen, you can work with one plot for each color you need, like demonstrated in this reference sample - http://www.ninjatrader-support2.com/...ead.php?t=3227

        // Dynamically change the primary plot's color based on the indicator value
        protected override void OnBarUpdate()
        {
        if (Value[0] > 100)
        Plots[0].Pen = new Pen(Color.Blue);
        else
        Plots[0].Pen = new Pen(Color.Red);
        }

        So why it doesn't work ?
        Using 2,3 or even more plots for displaying different colors for different value intervals seems to me wasteful, both regarding performance and the scare memory resource.

          xTrader1,

          Please follow the example shown in the reference sample. In NT7 you will have the ability to do it from a single plot.

            This changes the whole plot to the new color every time. If you just want the section to change, you need the two plots to do so.

              I tried it and I know. I just used their own sample, and thought there is one plot workaround.
