Quote from PointOne:
Sure, happy to help:
For any market, on any time frame, price Continues to progress, up and down, within a sloped channel until market sentiment Changes and price begins to follow a new channel of opposite slope. When the SCT trader sees signs of Change on the time-frame he is monitoring he reverses, otherwise he holds (having decided to enter in the first place on seeing Change). The rate of change of volume helps the trader differentiate between Continuation and Change, provided sufficient liquidity exists.
