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; 204 of these 379 calls were flat.

Ask about EXR
Why did the score rise from +35 to +42 this week?
It was mostly one day. The composite was +8.6 on 8 Oct, then rose to +41.8 on 9 Oct as the price moved from $133.25 to $133.12. It’s at +41.8 now.

Today’s +41.8 breaks down as +46.7 from volume and −4.8 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.
