Keltner Channels
Similar to Bollinger Bands, but instead of standard deviation, it uses the Average True Range (ATR) for the bands.
Formula:
Middle Line: Exponential Moving Average (EMA)
Upper Band: EMA + (Multiplier × ATR)
Lower Band: EMA - (Multiplier × ATR)
Use Case: Tracks volatility while being smoother than Bollinger Bands.
