Spot $511.65 highlighted. The $529 strike holds the most open interest (the “wall”, 6,425). 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; 441 of these 657 calls were flat.

Ask about DIA
Why did the score rise from −8 to +19 this week?
It was mostly one day. The composite was +2.2 on 8 Oct, then rose to +19.3 on 9 Oct as the price moved from $515.81 to $515.81. It’s at +19.3 now.

Today’s +19.3 breaks down as +7.8 from volume and +11.6 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.
