Close-to-close price changes, excluding dividends and costs. — means future or unavailable. Predictive value is unverified.
Dealer gamma stacked at each strike. The dashed lines are this week's ±1σ edges, so whether a thick strike and a band edge land on the same price is readable in one view.
Hedging leans against the move, so the strikes below tend to hold.
+1σ $1,949.71 · −1σ $1,605.89 — outside the published strike window ($1,740.00–$1,820.00), so not drawn on the ladder above.
All expirations, strikes within ±10% of spot. Open interest settles once a day, so these levels move on the same cadence as the σ band.
