Donchian Channel is the classic turtle-trader band: upper rail = highest high of the lookback, lower rail = lowest low. - Breakouts above/below the rails are the original trend entries. - A flat channel (rails pinned) = range regime; ride the rails back to the middle.
Keltner Channel uses an EMA of the typical price plus/minus an ATR envelope — smoother than Bollinger and a common trend filter. - Price above the upper rail = trend up; below the lower rail = trend down. - Channel width tracks ride regime; tight KC + BB squeeze = coiled spring.
Bollinger Bands plot a moving average plus/minus an envelope that scales with recent volatility (StdDev of the source). - Squeeze = bands pinch together → low volatility, expect a breakout. - Walk = price hugging the upper band → strong trend, lower band → strong downtrend. - Crosses of the outer band are common mean-reversion entry zones.
