Spot $42.42 highlighted. The $40 strike holds the most open interest (the “wall”, 16,843). Near-dated expiry in the mix, so OI is noisier.

One rule everywhere: a move of 0.05% or less is flat, and flat is not a hit. That is the same rule Proof uses; 168 of these 903 calls were flat.

Ask about BSX
What is behind today’s −8.7?
The composite has held within 2.4 points of −8.7 across the last 8 sessions.

Today’s −8.7 breaks down as −6.4 from volume and −2.2 from open interest. I can’t split past days the same way: the stored history keeps call/put volume but not open interest for past days.
