Keltner Channel

Definition

Keltner Channel indicator is based on volatility using a pair of values placed as an "envelope" around the data field.

Syntax
KeltnerChannel(double offsetMutiplier, int period)
KeltnerChannel(IDataSeries inputData, double offsetMutiplier, int period)

Returns midline value
KeltnerChannel(double offsetMutiplier, int period)[int barsAgo]
KeltnerChannel(IDataSeries inputData, double offsetMutiplier, int period)[int barsAgo]

Returns upper band value
KeltnerChannel(double offsetMutiplier, int period).Upper[int barsAgo]
KeltnerChannel(IDataSeries inputData, double offsetMutiplier, int period).Upper[int barsAgo]

Returns lower band value
KeltnerChannel(double offsetMutiplier, int period).Lower[int barsAgo]
KeltnerChannel(IDataSeries inputData, double offsetMutiplier, int period).Lower[int barsAgo]

Return Type
double; Accessing this method via an index value [int barsAgo] returns the indicator value of the referenced bar.

Parameters
offsetMultiplier	Value indicating the expansion offset
period	The number of bars to include in the calculation
inputData	Indicator source data (?)

Examples

// Prints the current upper value of a 20 period KeltnerChannel using default price type
double value = KeltnerChannel(1.5, 20).Upper[0];
Print("The current KeltnerChannel upper value is " + value.ToString());

// Prints the current lower value of a 20 period DonchianChannel using high price type
double value = KeltnerChannel(High, 1.5, 20).Lower[0];
Print("The current KeltnerChannel lower value is " + value.ToString());
