Historical Data

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.
VIX index (spot) values are the intraday values of the index only. This data is available starting from January, 1992. The frequency of the VIX index values is every minute for data prior to 2004 and every 15 seconds, including milliseconds, from 2004 and after.
