A channel and a range would not be the same thing. A channel contains trending price action, while a trading range defines a congestion.
There are many indicators, which indicate congestion phases, for example
(1) Bollinger Bands contract when price enters a congestion. The squeeze indicator, which is based on Bollinger Bands and Keltner Channels detects congestions.
(2) There is a number of adaptive moving averages, which indicate chop zones by plotting a horizontal line. One of the grandfathers of these adaptive moving averages is the KAMA (Kaufman adaptive moving average). You can also check the download section of the forum for the ADXVMA
(3) There are also indicators that determine the bar overlap. I remember a recent contribution from shodson concerning the congestion count.
(4) You can consider that all bars that close within the range of a prior expansion bars - consider them as inside closes - indicate a range. The first closes outside that range could be the start of a trend. You can fraw these ranges on a chart.
