Random article: Keltner Channel
Keltner Channel is an indicator of technical analysis, which is similar to Bollinger's. The indicator is based upon moving averages in the form of median moving value and an envelope, width of which is defined by change of price for an interval. This method was published in 1960 year in the book “How to make money in commodities” written by Chester W. Keltner. Later this indicator was updated by Linda Raschke with various averaging periods (exponential moving value) as well as by an Average True Range invented by Wilder for bands. Keltner Channel are used as signals of price breaks, figures of tendency, overbought and oversold figures for an asset. Such difference is crucial but despite that fact all those figures are called Keltner Channel thereby confusing everybody.
