Keltner Channels are a type of trading band indicator used in technical analysis to detect potential market reversals and trends. Unlike traditional price bands that use a fixed percentage for the envelopes, Keltner Channels employ the Average True Range (ATR) to create dynamic and adaptable price envelopes.
Historical Context
The concept of Keltner Channels was introduced by Chester W. Keltner in his 1960 book, “How to Make Money in Commodities.” The original formulation used a moving average and a fixed percentage for the bands. In the 1980s, technical analyst Linda Bradford Raschke popularized a modern version that utilizes the ATR, making the bands more responsive to market volatility.
Structure and Calculation
Keltner Channels consist of three components:
- Central Line: An exponential moving average (EMA) of the price.
- Upper Band: EMA + (ATR * Multiplier).
- Lower Band: EMA - (ATR * Multiplier).
Mathematical Formulas

Calculate the EMA:
$$ \text{EMA} = \left( \text{Price}_{t} \times \frac{2}{n+1} \right) + \left( \text{EMA}_{y} \times \left(1 - \frac{2}{n+1}\right) \right) $$where \( \text{Price}_t \) is the current price, \( n \) is the number of periods, and \( \text{EMA}_y \) is the EMA of the previous period. -
Calculate the ATR:
$$ \text{ATR} = \frac{\sum_{i=1}^{n} \text{TR}_i}{n} $$where \( \text{TR} \) (True Range) is the maximum of: \( \text{Current High} - \text{Current Low} \), \( |\text{Current High} - \text{Previous Close}| \), or \( |\text{Current Low} - \text{Previous Close}| \). -
Upper and Lower Bands:
$$ \text{Upper Band} = \text{EMA} + (\text{ATR} \times Multiplier) $$$$ \text{Lower Band} = \text{EMA} - (\text{ATR} \times Multiplier) $$

Importance and Applicability
Keltner Channels are significant for several reasons:
- Trend Identification: They help traders identify the direction and strength of a market trend.
- Volatility Measurement: The use of ATR makes the bands adaptable to changing market conditions.
- Entry and Exit Signals: Traders use breaches of the upper and lower bands to signal entry or exit points.
Examples
- Bullish Signal: When the price breaks above the upper band, it may indicate an overbought condition and a potential trend reversal.
- Bearish Signal: When the price falls below the lower band, it may indicate an oversold condition and a potential trend reversal.
Considerations
- Parameter Selection: The number of periods and the ATR multiplier significantly affect the channels’ sensitivity.
- Market Conditions: Keltner Channels are more effective in trending markets and may provide false signals in ranging markets.
Related Terms
- Bollinger Bands: Another type of trading envelope using standard deviations.
- Moving Average: An average of a security’s price over a specified number of periods.
- Volatility: A statistical measure of the dispersion of returns for a given security.
Comparisons
- Keltner Channels vs. Bollinger Bands: Keltner Channels use the ATR for volatility measurement, whereas Bollinger Bands use standard deviations. Keltner Channels are smoother and may be less reactive to sudden price changes than Bollinger Bands.
Interesting Facts
- Origin: The original Keltner Channels did not use ATR. The modern version that incorporates ATR provides a more accurate reflection of market volatility.
