R&S indicator

Dear Panagiotis!

With this indicator I was trying to odtain the most important S&R lines withing the given number of bars.

I managed to obtain the highest and the lovest zones, as well as the fractals

But horisontal line it would not draw

here is the code:

using System;
using System.Linq;
using cAlgo.API;
using cAlgo.API.Indicators;
using cAlgo.API.Internals;
using cAlgo.Indicators;
using System.Collections.Generic;

namespace cAlgo.Indicators
{
    [Indicator(IsOverlay = true, TimeZone = TimeZones.RussianStandardTime, AccessRights = AccessRights.FullAccess)]
    public class NewPattern2 : Indicator
    {
        [Parameter("Source")]
        public DataSeries Source { get; set; }

        [Parameter("Look Back Days", DefaultValue = 100)]
        public int LookBackDays { get; set; }

        [Parameter("Average Zone width %", DefaultValue = 0.7)]
        public double ZoneWidth { get; set; }

        [Output("Main")]
        public IndicatorDataSeries Result { get; set; }

        private int zoneDivider;
        private string instance;
        private DateTime date1, today;
        private int barsTotalOnChart, bar1, bar2;

        protected override void Initialize()
        {
            instance = ToString() + ", " + Symbol.Code + ", " + TimeFrame + ", " + Account.BrokerName + ", " + Account.Number;
            date1 = MarketSeries.OpenTime.LastValue.AddDays(-LookBackDays);
            today = MarketSeries.OpenTime.LastValue;
            barsTotalOnChart = Chart.BarsTotal;
            bar1 = barsTotalOnChart - LookBackDays;
            bar2 = barsTotalOnChart;
            if (TimeFrame == TimeFrame.Daily)
            {
                zoneDivider = 1;
            }
            if (TimeFrame == TimeFrame.Hour4)
            {
                zoneDivider = 6;
