Spot $27.99 highlighted. The $28 strike holds the most open interest (the “wall”, 48,628). 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; 902 of these 1404 calls were flat.

Ask about PFE
What is behind today’s +24.9?
The composite has held within 1.1 points of +24.9 across the last 8 sessions.

Today’s +24.9 breaks down as +8.5 from volume and +16.4 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.
