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 $199.81. The $135 strike holds the most open interest (the “wall”, 66,291). 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; 126 of these 226 calls were flat.

Ask about XLK
What is behind today’s −57.5?
The composite has held within 0.5 points of −57.5 across the last 8 sessions.

Today’s −57.5 breaks down as −45.6 from volume and −11.8 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.
