# ITW Options Open Interest by Strike, Oct 21 Settlement

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.

The two archived books match. A zero archived difference is not proof that no contracts opened or closed; a repeated capture can also produce matching books.

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.
