NinjaScript > Language Reference > Common > AddDataSeries()

Definition

An index value of the current Bars object that has called the OnBarUpdate() method. In a multi-bars script, the OnBarUpdate() method is called for each Bars object of a script. This flexibility allows you to separate trading logic from different bar events.

Notes:

1.In a single Bars script this property will always return an index value of 0 representing the primary Bars and instrument the script is running on.

2.See additional information on running multi-bars scripts.

Property Value

An int value represents the Bars object that is calling the OnBarUpdate() method.

Syntax

protected override void OnStateChange() { if (State == State.Configure) { // Add a 5 minute Bars object: BarsInProgress index = 1 AddDataSeries(BarsPeriodType.Minute, 5); } } protected override void OnBarUpdate() { // Check which Bars object is calling the OnBarUpdate() method if (BarsInProgress == 0) { // A value of zero represents the primary Bars which is the ES 09-14 // 1 minute chart. // Do something within the context of the 1 minute Bars here } else if (BarsInProgress == 1) { // A value of 1 represents the secondary 5 minute bars added in OnStateChange() State.Configure // Do something within the context of the 5 minute Bars } }

protected override void OnStateChange()
{
if (State == State.Configure)
