Pick the 3 LARGEST VOLUME bars and plot to INCLUDE THE MOVEMENT FROM THE PREVIOUS CLOSE to show "KEY LEVELS" in stocks.
I think this is a worthwhile way to look for important "activity" in any stock or market and be aware of the mid-point of that bars activity as a key level.
I could paint the volume bars yellow also to indicate the bars too.
When you add this to your "Key Earnings Levels" you get an added dimension of important levels in a stock.
(Note: KEY EARNINGS LEVELS only work in equities).
