What Is Channel?
A channel is defined by two parallel trendlines that contain price action — a support trendline connecting swing lows and a resistance trendline connecting swing highs. Channels can be ascending (sloping up), descending (sloping down), or horizontal (range-bound). They represent a defined trading range where price oscillates between the upper and lower boundaries.
How Channel Works
Channels form when a trending market maintains consistent momentum — each pullback finds support at a similar distance from the highs. The midline of the channel often acts as an intermediate support/resistance level. A channel remains valid as long as price respects both boundaries; a break above or below the channel signals a change in momentum.
Why It Matters for Traders
Channels are excellent for both range trading and breakout trading. Range traders buy at channel support and sell at channel resistance. Breakout traders wait for a close above the upper boundary (or below the lower) with volume confirmation. The measured move target after a channel break is typically the width of the channel projected from the breakout point.
