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; 181 of these 403 calls were flat.

Ask about CB
Why did the score drop from +21 to −7 this week?
It was mostly one day. The composite was +21.1 on 2 Oct, then fell to −13.5 on 3 Oct as the price moved from $331.30 to $331.43. It’s at −6.9 now.

Today’s −6.9 breaks down as −11.4 from volume and +4.6 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.
