Can't get horizantal lines to draw

I'm trying to write a simple "indicator" which is really just a peice of code to store support and resistance levels (which I have found manually and manually added to the code).  It is not actually responding to price action in any way.  I just want to draw lines at arbitrary levels.  I am having trouble getting the DrawLine function to do anything.

The ChartObjects.DrawLine function wants x min and x max values and it has on overload that takes indexes and an overload that takes DateTimes. I would prefer to use DateTime.MinValue and DateTime.MaxValue, so that the levels cover the entire chart forever, but since that is not working, I have also tried using numerical x limits like 0-20, which is also not working. 

Here is the code

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

namespace cAlgo
{
    [Indicator(IsOverlay = true, TimeZone = TimeZones.UTC, AccessRights = AccessRights.None)]
    public class EURUSDSR : Indicator
    {
        [Output("Main")]
        public IndicatorDataSeries Result { get; set; }

        //[Parameter()]
        //public LineStyle LevelStyle { get; set; }

        [Parameter("Color", DefaultValue = "Gray")]
        public string LevelColorString { get; set; }

        private Dictionary<TimeFrame, List<double>> timeFrameLists = new Dictionary<TimeFrame, List<double>>();
        private Colors levelColor;


        private double[] levels1h = new double[] 
        {
            1.06,
            1.05
        };

        protected override void Initialize()
        {
            Enum.TryParse(LevelColorString, out levelColor);

            timeFrameLists.Add(TimeFrame.Hour, new List<double>(levels1h));
            foreach (TimeFrame thisTimeFrame in timeFrameLists.Keys)
            {
                Print("current timeframe = {0}, applying {1}", TimeFrame.ToString(), thisTimeFrame.ToString());
                if (TimeFrame > thisTimeFrame)
                    continue;


                foreach (double level in timeFrameLists[thisTimeFrame])
                {
                    DrawLevel(level, 1);
                }
            }

        }

        public override void Calculate(int index)
        {

        }

        private void DrawLevel(double level, double thickness)
        {
            Print("{0}", level);
            ChartObjects.DrawLine("$" + level, DateTime.MinValue, level, DateTime.MaxValue, level, Colors.Red);
            // levelcolor);
            //, thickness);
            //, LevelStyle);
        }
    }
}

I can tell from the logs that it is entering my DrawLevel method (with the given levels), but I am not seeing anything appear on my chart.  Am I missing something?
