Why won't this code print any value other than zero for the indicator?

Hi everyone:

See screen capture and code below. Despite hard-coding the public property being set to 4 by the bot, the indicator never displays a value other than zero.

Why? What am I missing?

It should pick up the value of the public property that is set by the bot, and then set the IndicatorDataSeries "UpwardBuy" to 4.

Thank you :-)

Indicator code:

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

namespace cAlgo
{
    [Levels(2, 1, 0)]
    [Indicator(IsOverlay = false, TimeZone = TimeZones.UTC, AccessRights = AccessRights.None)]
    public class ConditionsOfEntry : Indicator
    {
        [Output("UpwardSell", LineStyle = LineStyle.Solid, PlotType = PlotType.Line, LineColor = "Red")]
        public IndicatorDataSeries UpwardSell { get; set; }
        [Output("UpwardNeutral", LineStyle = LineStyle.Solid, PlotType = PlotType.Line, LineColor = "Yellow")]
        public IndicatorDataSeries UpwardNeutral { get; set; }
        [Output("UpwardBuy", LineStyle = LineStyle.Solid, PlotType = PlotType.Line, LineColor = "Lime")]
        public IndicatorDataSeries UpwardBuy { get; set; }

        public int UpwardCount { get; set; }

        //private const int UpwardMax = 5;
        public override void Calculate(int index)
        {
            //if (UpwardCount >= UpwardMax)
                UpwardBuy[index] = UpwardCount;
            //else if (UpwardCount > Math.Round(UpwardMax / 2.0, MidpointRounding.AwayFromZero))
            //    UpwardNeutral[index] = UpwardCount;
            //else
            //    UpwardSell[index] = UpwardCount;
        }

    }
}

Bot code:

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 TestBot : Robot
    {
        private string _positionLabel = String.Empty;
        private MarketSeries _marketSeries;
        private ConditionsOfEntry _c = new ConditionsOfEntry();

        protected override void OnStart()
        {
            _marketSeries = MarketData.GetSeries(Symbol, MarketSeries.TimeFrame);
            DataSeries series = _marketSeries.Close;
            _positionLabel = (MarketSeries.TimeFrame) + " " + Symbol.Code + " Test Bot";
            _c = Indicators.GetIndicator<ConditionsOfEntry>();
        }

        protected override void OnTick()
        {
            if (SumOfLongEntryConditions() >= 5)
                Print("Hello");
            else
                Print("Oh no!");
        }

        private int SumOfLongEntryConditions()
        {
            int _sumOfLongEntryConditions = 4;
            Print("_sumOfLongEntryConditions {0}", _sumOfLongEntryConditions);
            _c.UpwardCount = _sumOfLongEntryConditions; //set to 4
            return _sumOfLongEntryConditions;
        }
    }
}
