Where the positions sit

No per-strike chain is stored for this name yet, so we can’t show where the positions sit. The totals above still come from today’s chain.
Spot $1,059.63. The $1,100 strike holds the most open interest (the “wall”, 1,145). 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; 155 of these 380 calls were flat.

Ask about BLK
Why did the score rise from +1 to +8 this week?
It was mostly one day. The composite was +1.2 on 3 Oct, then rose to +7.7 on 4 Oct as the price moved from $1,059.63 to $1,059.63. It’s at +7.7 now.

Today’s +7.7 breaks down as −2.1 from volume and +9.7 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.
