Our end-of-day option quotes witch 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.

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.

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.

Order Book data on cryptocurrencies such as Bitcoin and Ethereum recorded by Gemini, a digital asset exchange. The offering shows open orders at the beginning of the day, orders placed, filled, and canceled during the day and are distinguished by the Event Type field. A filter to only receive the Fill events is also available. Auction data is not included. The currency pair symbols are formatted as CCY1CCY2 where prices are in CCY2 and quantities are in CCY1, the following pairs are supported:

Currency Pair	Quantity currency	Price currency
BTCUSD	BTC	USD
ETHUSD	ETH	USD
ETHBTC	ETH	BTC
ZECUSD	ZEC	USD
ZECBTC	ZEC	BTC
ZECETH	ZEC	ETH

The Gemini marketplace conducts auctions for certain trading pairs every day (including weekends and holidays), which foster moments of elevated liquidity and price discovery. The Auction file contains the auction-only order book for the 4pm ET BTCUSD, ETHUSD, or ZECUSD auction on the Gemini exchange on weekdays (non-NYSE holidays).

The auction-only order book supports both market and limit orders. These orders rest on the auction-only book until the auction runs. Auction-only orders may be placed up until the auction runs but may not be cancelled after the final indicative price is published at 3:50pm ET

Only auction-only orders that were explicitly accepted to the book show up in this file. Orders that were placed but rejected due to insufficient funds or self-cross do not show up in this file. There is not an explicit close event portrayed in this file. An auction-only order is closed and off the books when that order id is either cancelled or filled with no quantity remaining. Fill events are portrayed as a single rows for each order filled during the auction; both continuous book and auction book orders may be filled. Auction-only orders are distinguished by the Execution Option value auction-only.
