What the fields let you inspect
Compare bid and ask quotes, volume and open interest. The files also include bid-side, ask-side and midpoint implied volatility, calculation flags and five Greeks where inputs support a calculation. Values are not guaranteed on every row.
Historical samples use SPX and SPXW as separate underlying values. Read expiration and settlement_time for each series; the current root mapping does not prove that historical roots are interchangeable.
Quotes across contracts are not synchronized snapshots. The overall archive begins in February 2002, but that date does not establish the start of SPX coverage. Confirm a historical research window before purchase.
