Spot $21.96 highlighted. The $17.50 strike holds the most open interest (the “wall”, 2,091). 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; 188 of these 387 calls were flat.

Ask about MBUU
Why did the score rise from −77 to −53 this week?
It was mostly one day. The composite was −66.3 on 2 Oct, then rose to −51.8 on 3 Oct as the price moved from $22.83 to $23.01. It’s at −53.5 now.

Today’s −53.5 breaks down as −39.4 from volume and −14.1 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.
