Spot $57.45 highlighted. The $75 strike holds the most open interest (the “wall”, 1,925). 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; 1618 of these 2000 calls were flat.

Ask about BAND
Why did the score drop from +75 to −5 this week?
It was mostly one day. The composite was +70.1 on 7 Oct, then fell to −5.1 on 8 Oct as the price moved from $62.53 to $62.53. It’s at −5.1 now.

Today’s −5.1 breaks down as −25.8 from volume and +20.8 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.
