Using IDataSeries with Secondary Chart Series

[TAJTrades]

What is the correct way to use IDataSeries when accessing a Secondary Chart Series.

This is the code I am using. All the indicator is doing is getting the Secondary Chart Series DoubbleStochasctics and Printing out the Bar Time and Indicator Value. Then it passes the dataseries to a method that prints the Time and Indicator Values for the three previous bars. What am I doing wrong? Is this not a correct use for IDataSeries? Is there another way of accomplishing the same thing?

        #region Variables
        // Wizard generated variables
            private int period = 10;
        
            private PeriodType     secondary_ChartType        = PeriodType.Minute;
            private int         secondary_ChartInterval = 5;                    
        
        
        // User defined variables (add any user defined variables below)
        
            private DataSeries SecondaryDoubleStochastics;
        
        #endregion

        /// <summary>
        /// This method is used to configure the indicator and is called once before any bar data is loaded.
        /// </summary>
        protected override void Initialize()
        {
            Overlay                = true;
            
            Add(Secondary_ChartType, Secondary_ChartInterval);  //  Bars Array 1
            SecondaryDoubleStochastics = new DataSeries(this); 
            
        }

        private void PrintSecondarySeries(IDataSeries CurrentSeries)
        {
            Print("    Print From Method");
            
            //  Loop back to get the 3 most recent Time and Values
            for (int index = 0; index < 3; index++) 
                Print(String.Format("    Time: {0}   SecondaryDoubleStochastics: {1}", Time[index], SecondaryDoubleStochastics[index]    ));
        }
        
        
        protected override void OnBarUpdate()
        {
            // Sync Secondary DataSeries
            if(SecondaryDoubleStochastics == null)
                SecondaryDoubleStochastics = new DataSeries(SMA(BarsArray[1], 1));
            
            //  Secondary Series OnBarUpdate
            if(BarsInProgress == 1)
            {
                //  Set SecondaryDoubleStochastics
                SecondaryDoubleStochastics.Set(DoubleStochastics(Period)[0]);
                //  Print the CurrentBar Time and Value
                Print(String.Format("\r\nOnBarUpdate  New Bar {0}  SecondaryDoubleStochastics[0]: {1}", Time[0], SecondaryDoubleStochastics[0] )); 
                
                //    Call the Method and pass the DataSeries
                if(CurrentBar > 3)
                    PrintSecondarySeries(SecondaryDoubleStochastics);
            }
        } 

I am getting incorrect results as can be seem in the image.

I have attached the indicator.

Thanks for your help.

Hello,

You'll want to remove the data series from being set in Initialize()

SecondaryDoubleStochastics = new DataSeries(this);

Currently your null check won't evaluate to true so it doesn't get synced with the secondary series

Let me know if I can be of further assistance.

Thanks. As usual a prompt reply to an issue.
