Spot $268.75 highlighted. The $250 strike holds the most open interest (the “wall”, 1,642). 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; 363 of these 661 calls were flat.

Ask about GRMN
Why did the score drop from +10 to −10 this week?
It was mostly one day. The composite was +26.9 on 3 Oct, then fell to −2.6 on 4 Oct as the price moved from $281.16 to $281.16. It’s at −9.9 now.

Today’s −9.9 breaks down as −16.5 from volume and +6.7 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.
