## Open interest rose at the latest settlement, by ticker, expiry and type (2026-10-12)

Open interest change, not trades; it does not say which side opened or closed.

## Limits

- **Delayed at least 15 minutes.** Every figure is published at least 15 minutes after the chain capture it describes, and stamped with that capture time in Eastern time.
- **21 symbols intraday, about 200 end of day.** Intraday snapshots cover a fixed list of 21 symbols (major stocks, ETFs and the SPX index), not every optionable symbol. Open interest changes cover about 200 symbols from the nightly Cboe settlement archive.
- **The strikes we track, not the full book.** A chain capture is a window: up to 40 strikes around the money in each expiration from the Schwab chain, or every strike in the nearest expirations from the Cboe delayed chain. Totals, shares and ratios describe the strikes captured, and each snapshot states its own coverage.
- **Thin cells are withheld.** Every published total, ratio and share rests on at least 3 traded contracts (volume above zero; for open interest change, contracts whose open interest changed). A call or put side of one expiry below that is left out of every figure, shown as withheld, and counted in a footnote, so no difference between published numbers recovers it.
- **Session totals, not trades.** Volume is the session total read from chain snapshots, aggregated to ticker, expiry and call or put. There is no trade-by-trade record behind it, and no single trade is shown.
- **No buyer, seller or direction.** A chain cannot say who bought or sold, whether a contract was opened or closed, or whether it was one leg of a spread. Calls can be sold and puts can hedge stock, so no snapshot carries a direction.
- **Premium is an estimate.** Estimated premium is volume times the quote midpoint times 100 shares. It is labelled "est." wherever it appears.
- **Open interest arrives the next day.** Open interest is the prior settlement figure. Whether contracts stayed open is only known after the next settlement, which is when each snapshot gets its follow-up.
