Dynamically changing the plot color

[trader2be]

I have 4 plots that I would like to overlay on prices. Two plots are TSFs (one over a 20 period, the other over an 80 period) and the other two are averages of the first two (over a 5 period for the shorter TSF, over a 20 period for the longer TSF). If the TSF is greater than its average, both the TSF and the average should be green, otherwise they should be magenta. As there is apparently no way to determine the plot color for each bar, I have chose an implementation via .Min and .Max of the Plot objects (which required the creation of 8 plots instead of 4). But I can't make it work. Any advice would be appreciated (open to other ways of implementing this as well).

        protected override void Initialize()
        {
            Add(new Plot(Color.Green, PlotStyle.Line, "LTUp")); // Plot0
            Add(new Plot(Color.Magenta, PlotStyle.Line, "LTDn")); // Plot1
            Add(new Plot(Color.Magenta, PlotStyle.Line, "LTAvgUp")); // Plot2
            Add(new Plot(Color.Green, PlotStyle.Line, "LTAvgDn")); // Plot3
            Add(new Plot(Color.Green, PlotStyle.Line, "STUp")); // Plot4
            Add(new Plot(Color.Magenta, PlotStyle.Line, "STDn")); // Plot5
            Add(new Plot(Color.Magenta, PlotStyle.Line, "STAvgUp")); // Plot6
            Add(new Plot(Color.Green, PlotStyle.Line, "STAvgDn")); // Plot7
            CalculateOnBarClose    = true;
            Overlay                = true;
            PriceTypeSupported    = false;
        }

        /// <summary>
        /// Called on each bar update event (incoming tick)
        /// </summary>
        protected override void OnBarUpdate()
        {
            if (CurrentBar < 80) return;
            Values[0].Set(TSF(0,80)[0]); // LT Up
            Values[1].Set(TSF(0,80)[0]); // LT Dn
            Values[2].Set(EMA(Values[0],20)[0]); // LT Avg Up
            Values[3].Set(EMA(Values[0],20)[0]); // LT Avg Dn
            Values[4].Set(TSF(0,20)[0]); // ST Up
            Values[5].Set(TSF(0,20)[0]); // ST Dn
            Values[6].Set(EMA(Values[4],5)[0]); // ST Avg Up
            Values[7].Set(EMA(Values[4],5)[0]); // ST Avg Dn
            Plots[0].Min = EMA(Values[0],20)[0]; // Green when above EMA20
            Plots[1].Max = EMA(Values[0],20)[0]; // Magenta when below EMA20
            Plots[2].Min = TSF(0,80)[0]; // Green when below TSF80
            Plots[3].Max = TSF(0,80)[0]; // Magenta when above TSF80
            Plots[4].Min = EMA(Values[4],5)[0];  // Green when above EMA5
            Plots[5].Max = EMA(Values[4],5)[0]; // Magenta when below EMA5
            Plots[6].Min = TSF(0,20)[0]; // Magenta when below TSF20
            Plots[7].Max = TSF(0,20)[0]; // Green when above TSF20

trader2be,

You seem like you are trying to do multi-colored plots. Please see this reference sample for how to do them: http://www.ninjatrader-support2.com/...ead.php?t=3227

Hi Josh-

I've been using the SampleMultiColoredPlot indicator to highlight slope changes.

Would it be possible to add a sound or audio alert for slope changed to this indicator?

[NinjaTrader_Bertrand]

CoopGeko, yes this would be possible via custom coding as well - you would be using then the PlaySound() or Alert() methods in our NinjaScript language to achieve this.
