Where the positions sit calls traded strike puts traded
Spot $502.70 highlighted. The $500 strike holds the most open interest (the “wall”, 1,487). Near-dated expiry in the mix, so OI is noisier.

Why did the score rise from −28 to +3 this week?
FlowDesk
It was mostly one day. The composite was −28.2 on 30 Sep, then rose to +8.9 on 1 Oct as the price moved from $546.12 to $522.81. It’s at +3.1 now.+5.2 from volume and −2.0 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.
