How to Pass DataSeries to Custom Indicator?

[tornadoatc]

I am wondering if it is possible to pass a DataSeries to a Custom Indicator.

If so, can you please point me to an example?

I have been trying to do the following

        
      #region Variables
				private DataSeries 		highRef; 	
      
      protected override void Initialize()
      {
		      highRef 		= new DataSeries(this) ;
      }
      
      #region Properties
	[Browsable(false)]
        [XmlIgnore()]		
        public DataSeries HighRef
      {
         get { return highRef; }
	set { highRef.Set(Values); } 
       }

Thanks,
ATC

Hello ATC,

By default NinjaTrader will automatically add an overload method that will take a Data Series that can be used your calculations along with all of your other User Defined Variables. See attached image.

Will that be able to work with what you are trying to accomplish?

I am wondering if more than one (the default) DataSeries can be passed into class ...

Lets say I want my Indicator to work with two DataSeries called HighRef and LowRef but sometimes I want the HighRef to be based on High and sometimes I want HighRef based on High + 2*ATR(14) . LowRef would be similar, so want to pass in two DataSeries .

Otherwise I am thinking I could use an int variable and put the logic in the indicator saying something like:

if (highRefType == "H+ATR") HighRef.Set(High[0] + 2 * ATR(14)[0]) ;

etc ..

Hello ATC,

You may use the IDataSeries to be able to pass an array of prices such as a DataSeries to an Indicator. Our Help Guide has an example of this that you may view at the link below.

Let us know if we can be of further assistance.

Hello JC,

Is there any way to pass an iDataSeries into Indicator as a Parameter?

		#region Variables 
                private IDataSeries i_HighRef ; 


                [Description("High Reference for Stop Calculations")]
		[Category("Stop Parameters")]
		[Gui.Design.DisplayNameAttribute("\t High Reference for Stop Calculations")]
		public IDataSeries I_HighRef
		{
			get { return i_HighRef; }
			set { i_HighRef = (IDataSeries) value; }  // ???????? 
		}

Also, there doesn't seem to be a way to pass in High[0]. Say I change the above to a double. But when I try to enter value for double parameter I can't enter High[0].

Hello tornadoatc,

There would not be a supported way to pass a DataSeries or IDataSeries as a User Defined Parameter. You would have to use a custom method as shown in the example of the IDataSeries Help Guide.

you can pass it like a string and then inside code parse the string to the type you want to use.
