Keltner Channels
Developed by Chester Keltner, it’s a technical analysis line study. The Keltner Channels are drawn based on the Average True Range (ATR) and the 20-period Exponential Moving Average (EMA). The Upper Line is constructed by adding two ATR above the EMA (20), where the Lower Line is drawn by subtracting two ATR from the EMA (20). The ATR is calculated over ten periods. A Buy signal is generated when the price closes above the Upper Line. Conversely, a Sell signal is generated when the price closes below the Lower Line.
