Spot $13.24 highlighted. The $15 strike holds the most open interest (the “wall”, 5,886). 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; 194 of these 429 calls were flat.

Ask about CTVA
Why did the score drop from +60 to −16 this week?
It was mostly one day. The composite was +30.5 on 8 Oct, then fell to −15.6 on 9 Oct as the price moved from $11.92 to $13.84. It’s at −15.6 now.

Today’s −15.6 breaks down as −27.6 from volume and +12.0 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.
