Spot $163.58 highlighted. The $175 strike holds the most open interest (the “wall”, 5,319). 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; 153 of these 365 calls were flat.

Ask about MMM
What is behind today’s +1.0?
The composite has held within 1.9 points of +1.0 across the last 8 sessions.

Today’s +1.0 breaks down as −7.4 from volume and +8.4 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.
