A channel can be used as an entry pattern for the continuation of an established trend, as part of a trend following strategy. A channel forms when price action is controlled by 2 parallel, sloping lines and has tested each of these lines at least twice. An ascending channel indicates a bullish trend, with the support line connecting consecutive higher lows and the resistance line connecting consecutive higher highs.
A descending channel indicates a bearish trend, with the support line connecting consecutive lower lows and the resistance line connecting consecutive lower highs. Generally speaking, the support line of an ascending channel is a buy zone and the resistance line of a descending channel is a sell zone, while the opposing lines are profit-taking zones. A common stop level lies on the other side of the buy or sell zone. Conservative traders may look for additional confirmation before entering a trade. TradingView has a smart drawing tool
