I would like to have a zero horizontal line to show in the chart pane every time I bring up my created indicator. 
CODE:
DrawHorzLine(0.0, Color.Red, 1, LineStyles.Solid, "MyPane");
Can I use this code line in the Indicator Code Builder? If I can how and where would I put the code line in? Here is my indicator code. 
CODE:
using WealthLab.Core;
using System;
using System.Drawing;
using WealthLab.Indicators;

namespace WealthLab.Indicators
{
   public class My310 : IndicatorBase
   {
      //parameterless constructor
      public My310() : base()
      {
      }

      //for code based construction
      public My310(TimeSeries source, Int32 len1, Int32 len2)
         : base()
      {
         Parameters[0].Value = source;
         Parameters[1].Value = len1;
         Parameters[2].Value = len2;

         Populate();
      }

      //static Series method
      public static My310 Series(TimeSeries source, Int32 len1, Int32 len2)
      {
         return new My310(source, len1, len2);
      }

      //name
      public override string Name
      {
         get
         {
            return "My310";
         }
      }

      //abbreviation
      public override string Abbreviation
      {
         get
         {
            return "My310";
         }
      }

      //description
      public override string HelpDescription
      {
         get
         {
            return "Differance between two SMA";
         }
      }

      //price pane
      public override string PaneTag
      {
         get
         {
            return "310Pane";
         }
      }

      //default color
      public override Color DefaultColor
      {
         get
         {
            return Color.FromArgb(255, 0, 0, 255);
         }
      }

      //default plot style
      public override PlotStyles DefaultPlotStyle
      {
         get
         {
            return PlotStyles.Line;
         }
      }

      //populate
      public override void Populate()
      {
         TimeSeries source = Parameters[0].AsTimeSeries;
         Int32 len1 = Parameters[1].AsInt;
         Int32 len2 = Parameters[2].AsInt;

         DateTimes = source.DateTimes;
         SMA sma3 = new SMA(source, len1);
         SMA sma10 = new SMA(source, len2);

         //modify the code below to implement your own indicator calculation
         for (int n = 0; n < source.Count; n++)
         {
            Values[n] = sma3[n] - sma10[n];
         }
      }

      //generate parameters
      protected override void GenerateParameters()
      {
         AddParameter("Source", ParameterTypes.TimeSeries, PriceComponents.Close);
         AddParameter("Len1", ParameterTypes.Int32, 3);
         AddParameter("Len2", ParameterTypes.Int32, 10);

      }
   }

No, DrawHorzLine and other WealthScript methods cannot be used in an indicator.

But once you have your indicator displayed in it's pane, you can add your zero line.

Why i can't see the DrawHorzLine. I've tried many ways, but without success. Can anyone help me?

CODE:
 public class Munich : UserStrategyBase
    {

        private IndicatorBase _stochDLong;
        private IndicatorBase _stochDShort;
        private IndicatorBase _tgtAtrLong;

        public Munich() : base()

Because the array indexes are all wrong. Remember, the count is zero-based:

using WealthLab.Backtest;

You're welcome Damir.

I have to say that topic starter's specific case has been answered from the start. Further general question re: DrawHorzLine may look confusing in this context. Let's lock the thread for replies then.
