Spot $199.50 highlighted. The $210 strike holds the most open interest (the “wall”, 12,032). 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; 185 of these 403 calls were flat.

Ask about COF
Why did the score drop from +55 to +11 this week?
It was mostly one day. The composite was +42.9 on 8 Oct, then fell to +10.8 on 9 Oct as the price moved from $195.91 to $199.40. It’s at +10.8 now.

Today’s +10.8 breaks down as −12.9 from volume and +23.6 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.
