What is a high-volume 20-day breakout?
This combines two conditions: a fresh 20-day high (a Donchian breakout to the upside) AND unusually heavy trading — at least twice the stock's own 30-day average volume on the breakout. The idea is that a new high made on a surge of volume reflects broader participation than a quiet drift to a new high.
How do I read the Broke out to a new 20-day high on heavy volume screen?
This screen lists companies that made a new 20-day high within the last few sessions while trading at 2x or more of their average volume, most recent breakout first. Requiring both conditions makes it far more selective than the plain breakout screen. It describes a past high made on heavy volume — not a prediction.
