Indicator Results Not Translating to Cbot

Hi,

Would anyone be able to assist with the below.

My indicator works fine and I can plot it on a chart and access the values. But when I declare the indicator into a test bot, then try to retrieve a value, it only ever returns one value.

CBOT:

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

namespace cAlgo.Robots
{
    [Robot(TimeZone = TimeZones.UTC, AccessRights = AccessRights.None)]
    public class Test2 : Robot
    {

        [Parameter(DefaultValue = 3, MinValue = 1)]
        public int HLPeriods { get; set; }

        private Test ATBHL;

        protected override void OnStart()
        {
            // Put your initialization logic here

            ATBHL = Indicators.GetIndicator<Test>(HLPeriods);

        }

        protected override void OnTick()
        {
            // Put your core logic here
        }

        protected override void OnBar()
        {
            // Put your core logic here

            Print("ATBHL.High.Last(0) = ", ATBHL.High.Last(0));
            Print("ATBHL.High.Last(1) = ", ATBHL.High.Last(1));
        }

        protected override void OnStop()
        {
            // Put your deinitialization logic here
        }
    }
}

INDICATOR:

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

namespace cAlgo
{
    [Indicator(IsOverlay = true, TimeZone = TimeZones.UTC, AccessRights = AccessRights.None)]
    public class Test : Indicator
    {
        [Parameter(DefaultValue = 3, MinValue = 1)]
        public int HLPeriods { get; set; }

        [Output("High", PlotType = PlotType.Points, LineColor = "Green", Thickness = 10)]
        public IndicatorDataSeries High { get; set; }

        [Output("Low", PlotType = PlotType.Points, LineColor = "Red", Thickness = 10)]
        public IndicatorDataSeries Low { get; set; }

        public double t1 = 0, t2 = 0, t3 = 0, t4 = 0;


        protected override void Initialize()
        {
            // Initialize and create nested indicators
        }

        public override void Calculate(int index)
        {
            // Calculate value at specified index
            // Result[index] = ...

            int e = 1;
            int f = 1;

            for (int a = 0; a <= HLPeriods; a++)
            {
                if ((Bars.HighPrices[index] > Bars.HighPrices[index + e]) && (Bars.HighPrices[index] > Bars.HighPrices[index - e]))
                {
                    e++;

                    if (e == HLPeriods + 1)
                    {
                        t2 = t1;

                        t1 = Bars.HighPrices[index];
                    }
                }
                else
                {
                    a = HLPeriods;

                    t1 = t1;
                }

            }

            for (int c = 0; c <= HLPeriods; c++)
            {
                if ((Bars.LowPrices[index] < Bars.LowPrices[index + f]) && (Bars.LowPrices[index] < Bars.LowPrices[index - f]))
                {
                    f++;

                    if (f == HLPeriods + 1)
                    {
                        t4 = t3;

                        t3 = Bars.LowPrices[index];
                    }
                }
                else
                {
                    c = HLPeriods;

                    t3 = t3;
                }
            }

            High[index] = t1;
            Low[index] = t3;

        }
    }
}

I have attached a photo below. Clearly the indicator is working on the chart and the values change, but the CBOT is not able to retrieve them.
