Spot $187.75 highlighted. The $200 strike holds the most open interest (the “wall”, 22,182). 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; 1140 of these 2000 calls were flat.

Ask about BA
Why did the score rise from +33 to +37 this week?
It was mostly one day. The composite was +27.6 on 3 Oct, then rose to +41.9 on 4 Oct as the price moved from $193.80 to $193.56. It’s at +37.0 now.

Today’s +37.0 breaks down as +24.6 from volume and +12.4 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.
