How to read this
- Is this real-time?
- No. Open interest is published once per session from the Cboe settlement archive. This page compares two completed settlement snapshots and is refreshed once per session before the open.
- Is a build bullish?
- An increase in open interest at a strike means more contracts are open there than at the prior settlement. It does not record which side initiated the change or why positions were added.
- Where does the data come from?
- Cboe delayed quotes, archived at settlement. Each row is one strike and expiration with the change in reported open interest between two settlement dates.
