Our daily summary contains two market snapshots, one at 15:45 U.S. Eastern and another at end-of-day (market closing time is product dependent). Each snapshot contains the best bid and ask (NBBO) for every option series along with size. The end-of-day (EOD) snapshot has open, high, low, and closing prices (OHLC), trade volume, VWAP, and open interest.
As an additional purchase option, we provide calculations at the 15:45 snapshot for implied volatility, Greeks, and implied underlying price. This time is used for analytics as it is considered a more accurate representation of market liquidity compared to end-of-day.
This data set includes Options on U.S. listed Stock, ETFs, and Indices disseminated over the Options Price Reporting Authority (OPRA) market data feed. Options on Futures & non-U.S. markets are *not* supported
