Exponential Keltner Channels Using an EMA and Average True Range

Summary

This document defines a Keltner Channel built around an exponential moving average of closing prices. The middle band is the exponential average over the selected period. Upper and lower bands are formed by adding and subtracting a multiple of the Average True Range calculated over that period. The example uses a period of 21 and a factor of 1.5.

The channel combines a smoothed price reference with a volatility-based measure of band width. A trader could use it to visualize price relative to its recent average and range, but the document does not prescribe a breakout, trend, or mean-reversion rule. It provides a formula and parameter example, not a backtest, market comparison, or evidence of profitability. Results would depend on the instrument, timeframe, parameter choices, and how signals and risk are handled.

Key ideas

• The middle Keltner band is an exponential moving average of closing prices.
• The channel width is based on Average True Range multiplied by a configurable factor.
• The example sets the period to 21 and the factor to 1.5.
• The document defines the indicator but does not evaluate trading rules or performance.
