PANW

Earnings: 2026-11-18 time unknown, stated by the vendor's estimate, first moves the 2026-11-18 session (57d on the tenor axis), no expected move served. As the vendor's calendar stood on 2026-09-22.

DTE counts calendar days from 2026-09-22, the page's date and the earliest an entry could be made - not from the 2026-09-18 book the expiries and IVs come from, which would overstate it by 4 days; an expiry first listed after 2026-09-18 is not in the book and not here. A premarket report moves its own session and a postmarket one the next; one with no stated time is placed at the earlier of the two - or at the later, once the earlier is already in the 2026-09-22 close - so an expiry can be called spanning when it might not be, never the reverse. "spans +N": the expiry settles N calendar days after that session, and the line under it says whether the 28-DTE exit comes before it ("inside the exit": that date is already behind 2026-09-22, so it protects nothing); "clear N": it settles N days before it. Thesis = DTE − 28 (the hard exit is 21), cut to the last session before a report that comes first. Every expiry in the band is listed, and one that is not a third Friday is marked weekly — §1 of the trading rules admits no weeklies and no 0DTE, so those rows are context, not candidates; the mark is the calendar test on the date alone, and a monthly pulled back to a Thursday by a holiday carries it too. ATM IV is the vendor's at the 2026-09-18 close, on the out-of-the-money side of the listed strike nearest book spot: a display selection, not a statistic, read at that one strike, so "no IV at X" is about X and not about its neighbours. The expected move is the vendor's, for the report the expiry spans. Every row links to that expiry on the strike axis below.

book spot $363.58 (unadjusted close, 2026-09-18) · call wall $400.00 (+10.02% from book spot) · put wall $350.00 (-3.74% from book spot) · max pain $330.00 (-9.24% from book spot, 2026-10-16 monthly)

Each level is stored as a distance from the book's own spot, so each is drawn at $363.58 × (1 + that distance) - the 2026-09-18 unadjusted close, the price the chain was taken at. That is why two prices appear on this page. PANW headlines $374.57, its newest unadjusted close, on 2026-09-22; the book was taken at $363.58 on 2026-09-18, because the book trails the page by the 2 sessions counted above. Both are closes, both are dated, and neither is adjusted. Recomputing a wall on the newer close would put it at a level this book never had, so none of these is: they are the 2026-09-18 book's levels, on the 2026-09-18 close.

Dashed: 7 DTE or less, where the vendor's gamma is noisy. "mp": the monthly max pain describes.

0DTE. This expiry settles at the 2026-09-18 close - the book date itself - so none of it is in the carried book the headline net GEX sums, and its gamma is the vendor's at the close of its last day, where the noise is worst. It can carry the opposite sign to the headline: here +$15.6m per 1% against the carried book's +$19.3m.

Tradability of the 2026-09-18 expiry: it expired 4 calendar days before 2026-09-22 (0 DTE on the book date), so no entry window applies. Spreads are the NBBO stored with the 2026-09-18 chain snapshot - not a live quote, and not DESIGN J's quote at a trade (per-trade quotes are not collected) - as a percent of mid; a zero or missing bid, or a crossed quote, is drawn as × for no two-sided quote. The owner's floors are marked and filter nothing: spread 10% of mid, OI 500, and the strike nearest 0.20 delta on each side - call 365 (Δ 0.25), put 360 (Δ -0.07).
