Hello ballboy11,

You would pass your data series to your custom class like the following,

public class myClassPivotPoint
{
		public DateTime Time;
		public int BarIndex;
		public int PivotType;

	
		public myClassPivotPoint(int nPivotType, DateTime tPivotTime, int nPivotBarIndex,[B] DataSeries s[/B])
		{
			PivotType = nPivotType;
			Time = tPivotTime;
			BarIndex = nPivotBarIndex;
			
			[B]mySeries=s;[/B]

		}
		
}

Declaring the data series in the indicator/strategy class,

	public DataSeries mySeries;

i think I don't need a dataseries what I needed was an object array. is there a way to have dynamic array in

private myClass[] myArray;
protected override void OnStartUp()
{
// ClearOutputWindow();
myArray = new myClass[10]; // instead of 10 size i want it dynamic


//Print("Current array size: "+myArray.Length.ToString());
}

Can I have a dynamic array size or do I have to set the length of the array?

Hello ballboy11,

You could use a list rather than an array. The advantages of a list is that it can dynamically change size. Please see the following,

As well as a sample I uploaded today which uses lists.

You can create a list in NT7?

[NinjaTrader_AlanP]

Hello ballboy11,

Yes. You would need to add the following using statements,

using System.Collections;
using System.Collections.Generic;

Then could declare the list with,

public List<int> myList;
