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.
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.
Volatility skew data allows users to analyze relative option pricing levels over time series by comparing “virtual” option strikes with identical time to maturity and levels relative to spot. Our Volatility Skew files show the implied volatility levels of virtual options expiring at constant maturities, with option strikes defined by either moneyness (% from spot) or by option delta. These files allow for more appropriate comparison of implied volatility levels over time. LiveVol volatility skew data is provided with either moneyness increments (5% steps from spot from 0-60%, with additional values at 2.5% from spot) or delta increments (5 delta increments for both calls and puts). Standard maturity periods range from 30 to 360 calendar days. An auxiliary set of skew index data will be provided with each purchase. Skew indexes represent a measure of option skew by symbol and maturity for a particular day. Delta skew data is used to generate the skew index metrics: for example, SKEW90 represents the (IV of 25 delta put – IV of 25 delta call)/(50 delta call IV) for virtual options expiring in 90 days.
MDR data is quotes and trades captured by Cboe’s internal data retrieval systems. MDR data is offered in the following Cboe exclusive indicies: ^VIX, ^SPX and ^OEX. The amount history available of the data varies by symbol; ^SPX from January 1990, ^OEX-January 1990 and ^VIX-March 2006. The MDR can typically fit onto a few DVDs, therefore, no surcharge is needed for additional hardware.
