Introduction
The Keltner Channel Indicator is a popular technical analysis tool that helps traders and investors identify a security’s underlying trend and potential volatility. It was developed in the 1960s by Chester W. Keltner, a well-known commodity trader and analyst who also created other technical indicators, such as the Keltner Summation and the Ten-Day Moving Average Trading Rule.
To form the Keltner Channel, two lines are drawn around a simple moving average (SMA) of the security’s price. The upper line is created by adding a multiple of the Average True Range (ATR) to the SMA, while the lower line is formed by subtracting the same multiple of ATR from the SMA. The ATR is a measure of volatility that considers the high and low prices of the security over a certain period.
The multiple used to calculate the Keltner Channel can be adjusted to fit the specific security and time frame being analyzed. Traders and investors can use the Keltner Channel Indicator to identify potential buy or sell signals. For instance, if the price of a security is trading near the upper band of the Keltner Channel, it may be viewed as overbought and could trigger a sell signal.
Conversely, if the price is trading near the lower band of the Keltner Channel, it may be seen as oversold and could indicate a buy signal. Additionally, the centerline of the Keltner Channel can serve as an indicator of the underlying trend, with prices above the centerline indicating an uptrend and prices below the centerline indicating a downtrend.
Computing the Keltner Channel Indicator
The Keltner Channel Indicator is typically calculated using the following formula:
Upper Band = SMA(Close, N) + (ATR(M, Close, N) x K)
Lower Band = SMA(Close, N) - (ATR(M, Close, N) x K)
Where:
SMA = Simple Moving Average;
Close = the closing price of the security;
N = the number of periods used to calculate the SMA;
ATR = Average True Range, a measure of volatility;
M = the number of periods used to calculate the ATR;
K = the multiplier used to adjust the distance between the upper and lower bands.
The Keltner Channel consists of the upper and lower bands, which are plotted on a chart to represent the channel’s space. ChartAlert ships with the Keltner Channel indicator.
Why the Keltner Channel Indicator is important in technical analysis?
Traders and investors rely on the Keltner Channel Indicator in technical analysis as it visually represents a security’s trend and volatility, providing insights for informed trading decisions.
The Keltner Channel consists of three lines: an upper band, a lower band, and a centerline. The upper and lower bands are established based on the Average True Range (ATR) of the security, a measure of volatility, while the centerline is usually a simple moving average (SMA) of the security’s price.
There are various ways in which the Keltner Channel Indicator can be interpreted by traders and investors. Here are a few examples:
Breakout signals
A breakout occurs when the price of a security moves above or below the upper or lower band of the Keltner Channel, respectively. These breakouts can be taken as potential buy or sell signals, depending on the direction of the breakout.
Trend analysis
The centerline of the Keltner Channel can be used as an indicator of the underlying trend. Prices above the centerline are typically seen as bullish, while prices below the centerline are typically seen as bearish.
Overbought/oversold signals
When the price of a security is trading near the upper band of the Keltner Channel, it may be considered overbought, signaling a potential sell. Conversely, when the price is trading near the lower band of the Keltner Channel, it may be considered oversold, signaling a potential buy.
It’s essential to note that traders should not rely on the Keltner Channel in isolation but should incorporate it with other technical indicators and analysis techniques to confirm trading signals and make informed decisions.
Chester Keltner’s suggestions on how to use the Keltner Channel Indicator

The Keltner Channel Indicator can be used in a variety of ways to guide traders and investors. Informed by Chester Keltner’s writings and observations, here are some practical guidelines and best practices for using the Keltner Channel Indicator:
Identify the trend
Determine the underlying trend direction by observing whether the price is consistently above or below the centerline. An uptrend may be indicated when the price is above the centerline, while a downtrend may be indicated when the price is below the centerline.
Look for breakouts
Identify potential buy or sell signals by watching for price breakouts above or below the upper and lower bands of the Keltner Channel, respectively.
Use multiple time frames
Confirm trading signals by comparing the Keltner Channel on different time frames. If there is a bullish trend on the daily chart, but a bearish breakout on the hourly chart, this may suggest that the uptrend is losing steam.
Adjust the parameters
Customize the Keltner Channel parameters to the specific security and time frame under consideration. For instance, the length of the SMA and the multiplier used to calculate the ATR can be adjusted to match the security’s volatility.
Pay attention to price-channel interaction
Observe how the price interacts with the Keltner Channel, and not just its position relative to the bands. A sustained move outside the Keltner Channel could signal a trend reversal, rather than a short-term overbought or oversold condition.
Combine with other indicators
Use the Keltner Channel in combination with other momentum and trend indicators, such as RSI or MACD, to confirm signals and obtain a more complete view of the security’s price action.
Consider the broader market
Take the overall market context into account when interpreting the Keltner Channel. If a particular stock shows a bearish breakout but the market as a whole is bullish, it may be best to wait for confirmation of a broader trend reversal before acting.
Manage risk
Set stop-loss orders and use appropriate position sizing based on risk tolerance.

Test and refine
Backtest the Keltner Channel strategy on historical data and refine it based on results. Monitor the strategy’s performance during real-time trading and make adjustments as necessary.
Overall, Keltner emphasized that trading strategies should be tailored to individual securities and market conditions, and that careful observation and analysis are key to successful trading.
Advantages & Limitations of the Keltner Channel Indicator
