Error CS0246 when adding a DataSeries?

[tradebot]

Hi All. I am trying to add a DataSeries for Position.AveragePrice and getting this error.

	The type or namespace name 'DataSeries' could not be found (are you missing a using directive or an assembly reference?)	CS0246	69	11

Code
using System;
using System.Collections.Generic;
using System.ComponentModel;
using System.ComponentModel.DataAnnotations;
using System.Linq;
using System.Text;
using System.Threading.Tasks;
using System.Windows;
using System.Windows.Input;
using System.Windows.Media;
using System.Xml.Serialization;

using NinjaTrader.Gui.Tools;
using NinjaTrader.Data;
using NinjaTrader.NinjaScript;
using NinjaTrader.Core.FloatingPoint;
using NinjaTrader.NinjaScript.Indicators;
using NinjaTrader.NinjaScript.DrawingTools;

namespace NinjaTrader.NinjaScript.Strategies
{
public class test : Strategy
{
private DataSeries BreakevenSeries;


and then
else if (State == State.Configure)
{
BreakevenSeries = new DataSeries(this);


What am I missing?

Thank

Please check this link , https://ninjatrader.com/support/help...price_data.htm. It might help.
you've got these below :

BreakevenSeries =new BreakevenSeries(this)

private Series<double> myDoubleSeries;

AddDataSeries(BarPeriodType.Seconds,3);

Hi, the link that you provided does not work. I am also having this same issue with creating a data series.

DataSeries was deprecated. I fixed the code using

private Series<double> realBreakeven;

and then

else if (State == State.Configure)
{
realBreakeven = new Series<double>(this);

Hope it helps.

Hello tradebot,

Emma1 is correct. NinjaTrader 8 uses a Series<T> object, the T in this would represent Type, as any data type can be stored in a series. In your case to store prices this would be a Series<double>.

Below is a link to the help guide.

Try using the Strategy Builder to add a custom series, and the view the code generated by clicking the View Code button.
