Bar heights share a scale within this stock's history. Off-exchange trades are reported after they cross, and the size alone does not tell us who traded or why.

How to read these figures

Every figure here is a total we compiled from that session's off-exchange prints. Above or below the midpoint says where a trade crossed against the quote. It does not say who was buying, and it has not told us which way a stock would move next.

Trader shows each print as it is reported, with the levels where size keeps landing.
