USB open interest settled 2026-10-21 vs 2026-10-20.
Source: SquawkFlow's archive of settled open interest. Counts are contracts, not trades; they do not identify which side opened or closed a position.
Computed from the Oct 21 settlement. Next update after the Oct 22 settlement, after 5:30 a.m. PT (8:30 a.m. ET) on Friday, Oct 23, 2026.
All archived unexpired expiration/strike/type keys, including unchanged counts. Series sharing that key are combined; roots and deliverables are not retained. Zero-OI keys omitted by the archive are not reconstructed.
This page shows the 6 nearest of 15 expirations, with the 40 strikes nearest the archived reference price (2026-10-21) for each, plus the largest changes across the whole book. The complete book, 501 expiration/strike/type keys, is in the Markdown table.
Strike bucket on the horizontal axis, settled open contracts per bucket on the vertical axis. Calls in the accent color; puts in orange. Totals across the 6 nearest expirations, strikes from 47 to 71. Source: SquawkFlow's archive of settled open interest. Counts are contracts, not trades; they do not identify which side opened or closed a position.
