Spot $154.34 highlighted. The $45 strike holds the most open interest (the “wall”, 30). 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; 457 of these 722 calls were flat.

Ask about MSTR
Why did the score rise from +27 to +63 this week?
It was mostly one day. The composite was +24.7 on 11 Oct, then rose to +63.1 on 12 Oct as the price moved from $154.90 to $154.34. It’s at +63.1 now.

Today’s +63.1 breaks down as +25.1 from volume and +38.0 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.
