Spot $278.94 highlighted. The $281 strike holds the most open interest (the “wall”, 10,504). 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; 1072 of these 2000 calls were flat.

Ask about IWM
Why did the score rise from −38 to +17 this week?
It was mostly one day. The composite was −32.6 on 6 Oct, then rose to +2.5 on 8 Oct as the price moved from $281.52 to $281.52. It’s at +17.3 now.

Today’s +17.3 breaks down as +16.8 from volume and +0.4 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.
