Indicator lines (2 colors)

Hey, here is workaround I use. Notice that I define previous value of series as well to make sure discontinuous line are plotted properly.

using System;
using cAlgo.API;
using cAlgo.API.Internals;
using cAlgo.API.Indicators;
using cAlgo.Indicators;

namespace cAlgo
{
    [Levels(20, 80)]
    [Indicator(IsOverlay = false, TimeZone = TimeZones.UTC, AccessRights = AccessRights.None)]
    public class StochasticColored : Indicator
    {
        [Output("Result", Color = Colors.Gray)]
        public IndicatorDataSeries Result { get; set; }

        [Output("Overbought", Color = Colors.LimeGreen, Thickness = 2, PlotType = PlotType.DiscontinuousLine)]
        public IndicatorDataSeries Overbought { get; set; }

        [Output("Oversold", Color = Colors.Red, Thickness = 2, PlotType = PlotType.DiscontinuousLine)]
        public IndicatorDataSeries Oversold { get; set; }

        private StochasticOscillator stoch;

        protected override void Initialize()
        {
            stoch = Indicators.StochasticOscillator(9, 3, 9, MovingAverageType.Simple);
        }

        public override void Calculate(int index)
        {
            Result[index] = stoch.PercentK.LastValue;

            if (Result[index] > 80)
            {
                Overbought[index - 1] = Result[index - 1];
                Overbought[index] = Result[index];
            }

            if (Result[index] < 20)
            {
                Oversold[index - 1] = Result[index - 1];
                Oversold[index] = Result[index];
            }
        }
    }
}

Result:

Very clever from you , thank you 

it does catch some values outside the range (30-70 or whatever the range) , but it's much more convenient than what i did  .

thanks mate

RE:

If you want to filter that, you might apply this method, although it's kinda sketchy.

using System;
using cAlgo.API;
using cAlgo.API.Internals;
using cAlgo.API.Indicators;
using cAlgo.Indicators;

namespace cAlgo
{
    [Levels(20, 80)]
    [Indicator(IsOverlay = false, TimeZone = TimeZones.UTC, AccessRights = AccessRights.None)]
    public class StochasticColored : Indicator
    {
        [Output("Result", Color = Colors.Gray)]
        public IndicatorDataSeries Result { get; set; }

        [Output("Overbought", Color = Colors.LimeGreen, Thickness = 2, PlotType = PlotType.DiscontinuousLine)]
        public IndicatorDataSeries Overbought { get; set; }

        [Output("Oversold", Color = Colors.Red, Thickness = 2, PlotType = PlotType.DiscontinuousLine)]
        public IndicatorDataSeries Oversold { get; set; }

        private StochasticOscillator stoch;

        protected override void Initialize()
        {
            stoch = Indicators.StochasticOscillator(9, 3, 9, MovingAverageType.Simple);
        }

        public override void Calculate(int index)
        {
            Result[index] = stoch.PercentK.LastValue;

            // Overbought
            if (Result[index] > 80)
            {
                if (Result[index - 1] < 80)
                    Overbought[index - 1] = 80;
                    
                Overbought[index] = Result[index];
            }
            else if (Result[index - 1] > 80 && Result[index] < 80)
                Overbought[index] = 80;

            // Oversold
            if (Result[index] < 20)
            {
                if (Result[index - 1] > 20)
                    Oversold[index - 1] = 20;
                    
                Oversold[index] = Result[index];
            }
            else if (Result[index - 1] < 20 && Result[index] > 20)
                Oversold[index] = 20;
        }
    }
}

I think this is the best possible hack 

Thanks again mate
