Problem: Indicators such as EMA are returning null values even after initialization while debugging.

I have been working on getting the Visual Studio debugger to debug a sample BOT code I've written. I compiled the following code into a dll first using Visual Studio.

using System;

using cAlgo.API;

using cAlgo.API.Indicators;

using cAlgo.API.Internals;

using cAlgo.API.Requests;

using cAlgo.Indicators;

using System.Collections;

using System.Collections.Generic;

namespace Rsi.TradeLibrary

{

    [Robot(TimeZone = TimeZones.UTC)]

    public class SampleBot : Robot

    {

          //Global Variables

          [Parameter("MA Type")]

          public MovingAverageType MAType { get; set; }

         [Parameter("Source")]

         public DataSeries SourceSeries { get; set; }

         [Parameter("Slow Periods", DefaultValue = 20)]

         public int SlowPeriods { get; set; }

         [Parameter("Fast Periods", DefaultValue = 10)]

         public int FastPeriods { get; set; }

         public ExponentialMovingAverage slowMa;

         public ExponentialMovingAverage fastMa;
 

         protected override void OnStart()

         {

             Print("Debugging Started");

             FastPeriods = 10;
             SlowPeriods = 20;

             fastMa = Indicators.ExponentialMovingAverage(SourceSeries, FastPeriods);
             slowMa = Indicators.ExponentialMovingAverage(SourceSeries, SlowPeriods);
 

         }
    }
}

I then referenced the dll in cAlgo IDE and was able to build successfully. I was also able to attach the debugger to cAlgo.exe process. I've verified that the control goes to OnStart method and gets executed fine by placing a breakpoint. However, SourceSeries value does not get initialized. It just always stays Null.

//#reference:..\..\..\..\Rsi.TradeLibrary\Rsi.TradeLibrary\bin\Debug\Rsi.TradeLibrary.dll

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)]
     public class RsiTradeBot : Rsi.TradeLibrary.SampleBot
     {

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

  
             base.OnStart();
         }

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

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

Am I missing something? Can somebody please help me figure this out so I can debug the code correctly?

Thanks.
