Keltner Channels

volatility📊 1H, 4H, Daily

Volatility-based envelopes using EMA and ATR, similar to Bollinger Bands but smoother.

Formula

Code

Middle = EMA(Close, 20)

Upper = Middle + (ATR × 2)

Lower = Middle - (ATR × 2)

Detailed Explanation

Keltner Channels use EMA for the middle band and ATR for the channel width, making them smoother than Bollinger Bands.

Components:
- Middle: 20-period EMA
- Upper: Middle + (2 × ATR)
- Lower: Middle - (2 × ATR)

Keltner vs Bollinger:
- Keltner uses ATR (smoother)
- Bollinger uses Standard Deviation (more reactive)
