Where the positions sit calls traded strike puts traded
Spot $947.92 highlighted. The $950 strike holds the most open interest (the “wall”, 3,147). Near-dated expiry in the mix, so OI is noisier.

Why did the score rise from +9 to +20 this week?
FlowDesk
It was mostly one day. The composite was +12.2 on 7 Oct, then rose to +20.1 on 8 Oct as the price moved from $935.68 to $942.25. It’s at +19.6 now.+16.7 from volume and +2.8 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.
