Keltner Channels are volatility-based envelopes set above and below an exponential moving average. Unlike Bollinger Bands which use standard deviation, Keltner Channels use the Average True Range (ATR) to set channel width, making them smoother and more consistent in trending markets.
What are Keltner Channels?
Keltner Channels consist of three lines that form a volatility envelope around price:
- Middle Line: A 20-period exponential moving average (EMA)
- Upper Channel: EMA + (2 x ATR)
- Lower Channel: EMA - (2 x ATR)
Key concept: Keltner Channels are smoother than Bollinger Bands because ATR measures average volatility over time, while standard deviation can spike dramatically on single large moves.
Keltner Channel Calculation
Understanding the calculation helps you use Keltner Channels effectively:
Step 1: Calculate the Middle Line
- Middle Line = 20-period EMA of Close
Step 2: Calculate ATR
The Average True Range uses the greatest of these three values:
Current High minus Current Low
Absolute value of Current High minus Previous Close
Absolute value of Current Low minus Previous Close
ATR = 10-period average of True Range
Step 3: Calculate Channel Lines
- Upper Channel = EMA + (Multiplier x ATR)
- Lower Channel = EMA - (Multiplier x ATR)
Calculation Example
Stock XYZ current values:
20-period EMA: $100
10-period ATR: $2.50
Multiplier: 2
Upper Channel = $100 + (2 x $2.50) = $105
Lower Channel = $100 - (2 x $2.50) = $95
Price trading between $95 and $105 is within normal volatility range.
Keltner Channel Signals
Price Position Analysis
- Price above upper channel: Strong uptrend, momentum breakout
- Price at upper channel: Bullish, potentially overbought
- Price at middle line: Neutral, near fair value
- Price at lower channel: Bearish, potentially oversold
- Price below lower channel: Strong downtrend, momentum breakdown
Channel Width
- Wide channels: High volatility period
- Narrow channels: Low volatility, potential breakout coming
Keltner Channel Trading Strategies
1. Channel Breakout Strategy
Trade momentum breakouts from the channels:
- Long entry: Price closes above upper channel
- Short entry: Price closes below lower channel
- Use the middle line as a trailing stop
Breakout Trade Example
Stock ABC has been consolidating. Keltner Channels are narrowing.
Price suddenly closes above the upper channel on increasing volume.
Enter long on the breakout with stop at the middle EMA line.
Trail the stop using the middle line as the trend continues.
Exit when price closes back below the middle line.
2. Mean Reversion Strategy
Trade pullbacks to the middle line in trending markets:
- In uptrends, buy when price pulls back to the middle line
- In downtrends, sell when price rallies to the middle line
- Confirm trend direction before using this strategy
3. Channel Bounce Strategy
Trade bounces off the channel boundaries in ranging markets:
- Buy when price touches the lower channel and shows reversal signs
- Sell when price touches the upper channel and shows reversal signs
- Target the middle line for initial profit
4. Squeeze Strategy
Trade the volatility expansion after consolidation:
- Watch for Keltner Channels to narrow significantly
- Prepare for a breakout in either direction
- Enter when price breaks out of the narrow channel
Keltner Channels vs Bollinger Bands
Key Differences
- Volatility measure: Keltner uses ATR, Bollinger uses standard deviation
- Smoothness: Keltner Channels are smoother and more consistent
- Responsiveness: Bollinger Bands react faster to sudden price spikes
- Squeeze signals: Bollinger Bands inside Keltner Channels = tight squeeze
TTM Squeeze Indicator
A popular combination uses both indicators:
- When Bollinger Bands move inside Keltner Channels, the squeeze is "on"
- When Bollinger Bands move outside Keltner Channels, the squeeze is "off"
- This identifies periods of extremely low volatility before major moves
Combining Keltner Channels with Other Indicators
Keltner + RSI
- Price at lower channel + RSI oversold = stronger buy signal
- Price at upper channel + RSI overbought = stronger sell signal
Keltner + MACD
- Channel breakout + MACD bullish crossover = confirmed uptrend
- Channel breakdown + MACD bearish crossover = confirmed downtrend
Keltner + Volume
- Channel breakouts on high volume are more reliable
- Low volume breakouts are more likely to fail
Keltner Channel Settings
- 20 EMA, 10 ATR, 2x multiplier: Standard settings
- 10 EMA, 10 ATR, 1.5x multiplier: More sensitive, short-term trading
- 50 EMA, 14 ATR, 2.5x multiplier: Smoother, position trading
Common Keltner Channel Mistakes
- Trading channel touches as automatic signals without confirmation
- Fighting strong trends when price stays outside the channels
- Using the same settings for all market conditions
- Ignoring the overall trend direction when mean reverting

Summary
Keltner Channels provide a smooth, ATR-based volatility envelope for identifying breakouts, pullback entries, and overbought/oversold conditions. Their consistency makes them particularly useful in trending markets where standard deviation-based indicators can be erratic. Use Keltner Channels for breakout trading, mean reversion entries during trends, and identifying volatility squeezes. Always combine with other technical tools and consider the overall market context.
