Historical Data

Cboe LiveVol Implied Volatility Blends capture term structure and solve for expiration-specific and constant maturity implied volatilities encapsulated within the range of option expirations. Capturing the constant maturity volatilities helps traders visualize and track the behavior of volatility over time providing context to current market implied volatility. To build out our volatility blends we first solve for the at-the-money volatility of each expiration to capture the term-structure of the volatility. Next, using a cubic spline approach, we fit a curve to the term-structure. Using the fitted curve, we solve for the constant maturity (IV30, IV60, IV90, etc.) time periods offered in the file. *Constant maturity times that fall outside the range of expirations available for a particular symbol will be zero. This dataset is only available with end of day granularity.
Open-Close data is a volume summary file of trading activity on the Cboe C1 exchange (does not include activity from C2, BZX, or EDGEX) that summarizes the volume (contracts traded) by origin (customer and firm orders only), original order size and the opening or closing position of the order. The Open-Close volume is further broken into categories of buy/sell, open/close and order size "buckets". The data for all Cboe (C1) securities goes back to 1990 and contains all series in an underlying security's chain-if it has volume. The Open-Close data is available as a data download by individual underlying symbols, or as a daily update that includes all Cboe (C1) traded options for the previous trade day's data going forward, and as bulk data that includes all Cboe (C1) traded securities for the time frame chosen.
