This consolidator can transform a stream of IBaseData instances into a stream of RangeBar. The difference between this consolidator and RangeConsolidator, is that this last one creates intermediate/ phantom RangeBar's (RangeBar's with zero volume) if the price rises up or falls down by above/below two times the range size. Therefore, RangeConsolidator leaves no space between two adyacent RangeBar's since it always start a new RangeBar one range above the last RangeBar's High value or one range below the last RangeBar's Low value, where one range equals to one minimum price change.

Constructor & Destructor Documentation

◆ ClassicRangeConsolidator() [1/2]

QuantConnect.Data.Consolidators.ClassicRangeConsolidator.ClassicRangeConsolidator	(	int	range,
		Func< IBaseData, decimal >	selector = `null`,
		Func< IBaseData, decimal >	volumeSelector = `null`
	)

Initializes a new instance of the ClassicRangeConsolidator class.

Parameters

range	The Range interval sets the range in which the price moves, which in turn initiates the formation of a new bar. One range equals to one minimum price change, where this last value is defined depending of the RangeBar's symbol
selector	Extracts the value from a data instance to be formed into a RangeBar. The default value is (x => x.Value) the IBaseData.Value property on IBaseData
volumeSelector	Extracts the volume from a data instance. The default value is null which does not aggregate volume per bar, except if the input is a TradeBar.

◆ ClassicRangeConsolidator() [2/2]

QuantConnect.Data.Consolidators.ClassicRangeConsolidator.ClassicRangeConsolidator	(	int	range,
		PyObject	selector,
		PyObject	volumeSelector = `null`
	)

Initializes a new instance of the RangeConsolidator class.

Parameters

range	The Range interval sets the range in which the price moves, which in turn initiates the formation of a new bar. One range equals to one minimum price change, where this last value is defined depending of the RangeBar's symbol
selector	Extracts the value from a data instance to be formed into a RangeBar. The default value is (x => x.Value) the IBaseData.Value property on IBaseData
volumeSelector	Extracts the volume from a data instance. The default value is null which does not aggregate volume per bar.
