Spot $406.81 highlighted. The $400 strike holds the most open interest (the “wall”, 8,111). 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; 164 of these 662 calls were flat.

Ask about AMGN
Why did the score drop from +32 to +0 this week?
It was mostly one day. The composite was +23.0 on 7 Oct, then fell to −0.1 on 8 Oct as the price moved from $402.98 to $413.08. It’s at −0.1 now.

Today’s −0.1 breaks down as +0.7 from volume and −0.8 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.
