 using PTLRuntime.NETScript.Indicators;

 namespace Indicators
 {
     public class IndicatorExample : NETStrategy
     {
         private Indicator indicator;
         public PriceType SourcePrice = PriceType.Close;

         public override void Init()
         {
             indicator = Indicators.iRSI(getPrice, 15, RSIMode.Exponential); // Индикаторы строящиея по кастомнуму типу данных не рисуются на чарте
         }

         private double getPrice(int index)
         {
             if ((index + 1) >= CurrentData.Count) return 0;

             return Math.Abs(CurrentData.GetPrice(SourcePrice, index) - CurrentData.GetPrice(SourcePrice, index + 1));
         }
     }
 }
