Provenance

Source: core.occ_open_interest
Cadence: daily, OCC clearing days
Read by: Data Explorer market panel; the denominator behind the put/call ratio
Point-in-time: IMMUTABLE
Export restriction: INHERITED FROM core.occ_open_interest, whose SourceSpec records the basis in full: OCC requires express written consent to redistribute its market data, and theocc.com returns HTTP 403 to every automated fetch so the terms could not be quoted first-hand. A ratio computed from restricted data is still restricted - a division is not a licence.
