Problmes with referring custom indicator's to cBot causing none executed trade in Backtesting

Hi guys, I am having problems by using(referring) my custom indicator's calculation result in(to) my cBot, I can't execute any trade in "Backtesting" but there are no errors showing up every time I build the code, I have checked lots of things I dont think is the cBot's error because when I use the built in indicator(RSI) it execute order and selling orders in Backtesting perfectly fine, so I think it's probably my calculation's format is doing wrongly?

I am a newbie on csharp, I will provide my indicator code and cBot code below for you guys to check, please help me out 🤝

This is the indicator code

```
using cAlgo.API;

namespace cAlgo
{
   [Indicator(IsOverlay = false, TimeZone = TimeZones.UTC, AutoRescale = true, AccessRights = AccessRights.None)]
   
   public class JINGXUANSOUL : Indicator
   {
       [Parameter("Source")]
       public DataSeries Source { get; set; }

       [Parameter(DefaultValue = 27)]
       public int Periods { get; set; }

       [Parameter(DefaultValue = 3)]
       public int SSSmooth { get; set; }

       [Parameter(DefaultValue = 3)]
       public int DDSmooth { get; set; }

       [Output("K", LineColor = "Blue", PlotType = PlotType.Line)]
       public IndicatorDataSeries SS { get; set; }

       [Output("D", LineColor = "Red", PlotType = PlotType.Line)]
       public IndicatorDataSeries DD { get; set; }

       [Output("J", LineColor = "Green", PlotType = PlotType.Line)]
       public IndicatorDataSeries KK { get; set; }
       
       [Output("KD", LineColor = "Green", PlotType = PlotType.Line)]
       public IndicatorDataSeries KD { get; set; }
       
       
       
       
       protected override void Initialize()
       {
           IndicatorArea.DrawHorizontalLine("OverBoughtH"    , 100   , Color.Orange);
           IndicatorArea.DrawHorizontalLine("OverBoughtL"    , 90    , Color.Orange);
           IndicatorArea.DrawHorizontalLine("OverSoldH"      , 10    , Color.Orange);
           IndicatorArea.DrawHorizontalLine("OverSoldL"      , 0     , Color.Orange);
       }

       public override void Calculate(int index)
       {
           var highestHigh = Source.Maximum(Periods);
           var lowestLow = Source.Minimum(Periods);
           var currentClose = Bars.ClosePrices;

           double rsv = 0;
           if (highestHigh != lowestLow)
               rsv = (currentClose[index] - lowestLow) / (highestHigh - lowestLow) * 100;

           var kPrev = index > 0 ? SS[index - 1] : 50;
           var dPrev = index > 0 ? DD[index - 1] : 50;

           var ss = (rsv + (SSSmooth - 1) * kPrev) / SSSmooth;
           var dd = (ss + (DDSmooth - 1) * dPrev) / DDSmooth;
           var kk = 3 * ss - 2 * dd;
           var kd = ((ss+dd)/2);

           SS[index] = ss;
           DD[index] = dd;
           KK[index] = kk;
           KD[index]  = kd;
       }
   }
}
```

and this is the cBot code
