Keltner Channels plot an EMA with upper and lower bands based on ATR, producing smoother envelopes than Bollinger Bands — and the two are frequently used together for the TTM Squeeze setup. This combination identifies low-volatility compression zones that precede explosive breakout moves in any market. Apply Keltner Channels on TradingView and overlay Bollinger Bands to spot squeeze conditions with a single glance.
Middle line = 20-period EMA. Upper channel = EMA + (2 × ATR). Lower channel = EMA − (2 × ATR). Because ATR changes more smoothly than standard deviation, Keltner Channels are less reactive to spikes.
