US Options Reference Data is a daily service offering comprehensive and validated information on US options. It covers options strikes and series for all available issues, including those that are maintained and expired in the open market. Users can identify all traded issues within the Standardized Options universe. The service provides End-of-Day (EOD) pricing details based on official closing values for both root and options symbols. Specialized files include Issue Extended Files with underlying symbol details and ETF identification, and Series Extended Files which are comprehensive masters of all listed options series, including next-day additions. Issue Deliverable files detail current deliverable values for all option symbols. Position Limit files, including Near-Term Position Limit files, provide exchange or regulator-established ownership thresholds to help financial firms manage risk. The Option Style file specifies contract and settlement styles (American/European, AM/PM). An Intraday update service is also available, providing hourly updates from 9 am to 4 pm Eastern to capture intraday strike additions and ensure trading platforms reflect real-time market activity, including for FLEX options.
