The calculation:
Keltner Mid = 20-period Exponential Moving Average (EMA)
Why EMA instead of SMA:
- More responsive: EMA gives more weight to recent prices
- Smoother tracking: Better follows current price action
- Faster signals: Reacts more quickly to trend changes
Role in Keltner Channels:
- Channel center: Baseline from which upper and lower bands are calculated
- Trend indicator: Direction shows overall trend
- Support/resistance: Dynamic support in uptrends, resistance in downtrends
Comparison to Bollinger Bands:
- Center line: Keltner uses EMA; Bollinger uses SMA
- Band width: Keltner uses ATR; Bollinger uses standard deviation
- Smoothness: Keltner bands are typically smoother
- Squeeze detection: Bollinger bands inside Keltner channels indicate squeeze
The Keltner mid line provides a responsive trend-following reference point. Trading above the mid line generally indicates bullish conditions; below indicates bearish conditions.
