DTE counts calendar days from 2026-09-18, the page's date and the earliest an entry could be made - not from the 2026-09-17 book the expiries and IVs come from, which would overstate it by 1 day; an expiry first listed after 2026-09-17 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 2026-09-18 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 2026-09-18, 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 2026-09-17 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.
Chain · one strike axis Book as of 2026-09-17 : 1 session behind 2026-09-18: no XLI chain statistics (net_gex) dated after 2026-09-17 are knowable as of 2026-09-18, and no ticker has newer ones. The strikes drawn below are 2026-09-17's rows as stored now; the levels and statistics are the readings dated 2026-09-17, computed from those rows when the readings were derived, and a fetch of 2026-09-17 after that can revise rows. Open interest is what entered 2026-09-17 (OCC's settlement of 2026-09-16), valued at the 2026-09-17 close.

book spot $169.01 (unadjusted close, 2026-09-17) · call wall $180.00 (+6.50% from book spot) · put wall $165.00 (-2.37% from book spot) · max pain $172.00 (+1.77% 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 $169.01 × (1 + that distance) - the 2026-09-17 unadjusted close, the price the chain was taken at. That is why two prices appear on this page. XLI headlines $169.75 , its newest unadjusted close, on 2026-09-18 ; the book was taken at $169.01 on 2026-09-17 , because the book trails the page by the one session 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 2026-09-17 book's levels, on the 2026-09-17 close.

Tradability of the 2026-10-16 expiry: 28 calendar days from 2026-09-18 (29 from the book date), outside the owner's 35–65 DTE entry window. Spreads are the NBBO stored with the 2026-09-17 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 177 (Δ 0.19), put 160 (Δ -0.16).
