@ M_Anjom  You are right, pitchfork wont disappear without Chart.RemoveObject("AndrewsPitchFork");

I will edit ASAP. I would also like to add a few more options like option to change fork color, switch zigzag on/off etc. Let me see. 

Thanks btw. 

Changing candle color algorithmically is possible now .  

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

namespace cAlgo.Indicators
{
    [Indicator(IsOverlay = true, AccessRights = AccessRights.None)]
    public class BreakOutCandles : Indicator
    {

        [Parameter("How Many Break Out Bars", DefaultValue = 5)]
        public int HowManyBreakOutCandles { get; set; }

        [Parameter("Breakout up color", DefaultValue = "Green")]
        public string UpColor { get; set; }

        [Parameter("Breakout down color", DefaultValue = "Red")]
        public string DownColor { get; set; }

        [Parameter("Range color", DefaultValue = "LightGray")]
        public string RangeColor { get; set; }

        private Color color;

        protected override void Initialize()
        {

        }
        public override void Calculate(int index)
        {
            try
            {
                var open = MarketSeries.Open[index];
                var close = MarketSeries.Close[index];
                var high = MarketSeries.High[index];
                var low = MarketSeries.Low[index];

                var highest = MarketSeries.High[index - 1];
                var lowest = MarketSeries.Low[index - 1];
                for (int i = 2; i <= HowManyBreakOutCandles; i++)
                {
                    if (highest < MarketSeries.High[index - i])
                        highest = MarketSeries.High[index - i];
                    if (lowest > MarketSeries.Low[index - i])
                        lowest = MarketSeries.Low[index - i];
                }

                if (close > highest && close > open)
                    color = Color.FromName(UpColor);
                else if (close < lowest && close < open)
                    color = Color.FromName(DownColor);
                else if (close > open)
                    color = Color.FromName(RangeColor);
                else if (close <= open)
                    color = Color.FromName(RangeColor);
                Chart.SetBarColor(index, color);
            } catch (Exception)
            {
            }

        }
    }
