Keltner Channels — what it is and how to use it in trading
Definition
Keltner Channels are a channel around price built from a middle line and ATR — the upper and lower boundaries sit multiplier average true ranges (ATR) away from the middle, rather than standard deviations as in Bollinger Bands, which makes the channel smoother and less noisy.
How it works in the builder
The keltner_upper and keltner_lower operands take period (default 20) and mult (default 2) parameters. The upper boundary is the middle line plus mult×ATR, the lower boundary is the middle line minus mult×ATR.
What it looks like on the chart
Drawn as candles inside a smooth, roughly constant-width channel around a dashed middle line — the chosen boundary (upper or lower) is highlighted as a bold solid line, the other as a thin muted one.
Typical use
A close beyond the upper or lower boundary is more often read as a trend-continuation signal, not overbought/oversold (unlike Bollinger's more mean-reversion-flavored reading). Typical condition: close > keltner_upper(20, 2) as a breakout entry filter.
Common pitfalls
Because the channel is built on ATR rather than a standard deviation, it is smoother and reacts more slowly to a sudden volatility spike than Bollinger Bands — a genuine volatility-regime change shows up in the channel's width with a delay. As with any channel, price can "walk along" one boundary for many bars without that alone being a reversal signal.
