Historical Data

Our end-of-day option quotes file actually provides two snapshots of market quote and size, one at 15:45 and another at the market close (market closing time is product dependent). Summary trading data is also included in the files. The first, last, lowest and highest trade in every series, as well as, the total volume, VWAP and open interest. Effective February 5, 2020 on half trading days, the value in the "1545" column will be taken at 12:45 pm ET and the column name of 1545 will be unchanged.

Our end-of-day option quotes with Calcs file provides all of the fields in the end-of-day Option quotes file plus market implied volatility for each option, as well as, the greeks (Delta, Gamma, Theta, Vega and Rho). Implied volatility and Greeks are calculated off of the 1545 timestamp, since it is considered a more accurate snapshot of market liquidity than the end of day market. Effective February 5, 2020 on half trading days, the value in the "1545" column will be taken at 12:45 pm ET and the column name of 1545 will be unchanged.
