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 $473.46. The $520 strike holds the most open interest (the “wall”, 956).

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; 134 of these 291 calls were flat.

Ask about NOC
What is behind today’s +18.0?
The composite has held within 1.2 points of +18.0 across the last 8 sessions.

Today’s +18.0 breaks down as +16.7 from volume and +1.3 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.
