EOD

FreeValueStandardPro

Fetch end-of-day option data for a contract over a date range.

• Since OPRA does not provide a national EOD report for options, Theta Data generates a national EOD report at 17:15 ET each day.
• created represents the datetime the report was generated and last_trade represents the datetime of the last trade.
• The quote in the response represents the last NBBO reported by OPRA at the time of report generation.
• You can read more about EOD & OHLC data here.

Wildcard requests additionally populate expiration (YYYYMMDD), strike (dollars), and right ("C" / "P") on every row to identify the contract; on single-contract requests these are absent (None / null / undefined; the Rust and C rows carry the documented 0 / 0.0 / '\0' fills).
