Option EOD Summary
  • Options

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 across exchanges. The end-of-day (EOD) snapshot has open, high, low, and closing prices (OHLC), trade volume, VWAP, and open interest.  The data covers Regular Trading Hours (RTH) only.

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.
