Limit the calculation to recent Bars only

You can limit the calculation to recent bars to make it feasible. Here is the code I suggest:

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

namespace cAlgo
{
    [Indicator(IsOverlay = false, TimeZone = TimeZones.UTC, AccessRights = AccessRights.None)]
    public class STOCHALLINONELoadMore : Indicator
    {
        //[Parameter("Nbrs Stoch Load  ", DefaultValue = 28, Group = " Ribbon/BarsColors Setting")]
        //public int NbrsStochLoad { get; set; }

        [Parameter("Percent K", DefaultValue = 9, Group = "Stoch Setting")]
        public int PeriodK { get; set; }
        [Parameter("Percent K", DefaultValue = 3, Group = "Stoch Setting")]
        public int PeriodD { get; set; }
        [Parameter("Percent K", DefaultValue = 9, Group = "Stoch Setting")]
        public int KSlowing { get; set; }

        [Parameter("Nbrs Stoch  Load", DefaultValue = 25, Group = "Nbrs Load")]
        public int StochLoad { get; set; }
        [Parameter("Periods Multi STOCH ", DefaultValue = 1.1, Group = "Nbrs Load")]
        public double PeriodsMulti { get; set; }

        [Parameter("Extra Level", DefaultValue = 80, Group = "Extra Level")]
        public int HighLevel { get; set; }
        [Parameter("Extra Level", DefaultValue = 20, Group = "Extra Level")]
        public int LowLevel { get; set; }

        [Output("Result", PlotType = PlotType.Line, LineColor = "Green", Thickness = 1)]
        public IndicatorDataSeries Result { get; set; }
        [Output("Signal", PlotType = PlotType.Line, LineColor = "Red", Thickness = 1)]
