What is Keltner Channels?

Keltner Channels place bands around a moving average using a multiple of Average True Range. Because ATR ignores closing dispersion, the channel width is usually steadier than Bollinger Bands.

Keltner Channels formula

Output	Calculation
Middle	EMA(close, period)
Upper	Middle + multiplier × ATR(atrLength)
Lower	Middle − multiplier × ATR(atrLength)

How to read Keltner Channels in your code

Signal	Meaning	Condition
Upside breakout	Strong momentum up	Close above `upper`
Downside breakout	Strong momentum down	Close below `lower`
Bias	Mean position	Close above or below `middle`

Limitations: Outside-channel closes are often continuation rather than reversal, and results depend heavily on the multiplier. Nothing on this page is financial advice.
