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 $221.61. The $240 strike holds the most open interest (the “wall”, 7,930). 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; 132 of these 257 calls were flat.

Ask about ROST
Why did the score drop from −25 to −42 this week?
It was mostly one day. The composite was −24.7 on 1 Oct, then fell to −41.6 on 2 Oct as the price moved from $233.40 to $234.18. It’s at −41.6 now.

Today’s −41.6 breaks down as −22.0 from volume and −19.6 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.
