Bars | NinjaTrader Developer Docs

Definition

Represents the data returned from the historical data repository. The Bars object contain several methods and properties for working with bar data.

The Bars object and its member should NOT be accessed within the OnStateChange() method before the State has reached State.DataLoaded

Additional Access Information

Members within the Bars class can be accessed without a null reference check in the OnBarUpdate() event handler. When the OnBarUpdate() event is triggered, there will always be a Bar object which holds the method or property. Should you wish to access these members elsewhere, check for null reference first. e.g. if (Bars != null)
