Bollinger Bands vs. Keltner Channels: Which Indicator to Use?
Both Bollinger Bands and Keltner Channels are volatility-based indicators, but they calculate price envelopes in different ways. If you’re wondering which one is better for your strategy, this comparison will help you decide.
What Are Keltner Channels?
Keltner Channels are a set of three lines:
- Middle Line: Exponential Moving Average (EMA)
- Upper & Lower Channels: EMA ± a multiple of the Average True Range (ATR)
