BarsInProgress

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. 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.

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

// Lets assume this sample script was added to a ES 12-06 1 minute chart

protected override void Initialize()
{
// Add a 5 minute Bars object: BarsInProgress index = 1
Add(PeriodType.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 12-06
// 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 the Initaliaze()
// Do something within the context of the 5 minute Bars
}
}
