2-Minute Raw Snapshots

Download this snippet here.

Bid - asks snapped before the close, giving you the highest quality markets back to 2007

HistoricalQuoteSnipWe take a complete snapshot of the US equity options market 14-minutes before the close of trading each day. Why 14 minutes before? Our ex-market makers and traders think that is the best time, the closest to the close without getting deterioration in markets that happens as the close of trading approaches.

Everything in the snapshot has the same time stamp, including underlying prices. Stock bid-ask mid points are calculated and presented with each option. Index futures prices at each expiration are implied from put-call parity, and spot prices are included.

These near end-of-day quote files are ready by 9 PM EST after each close via FTP.

Because these quotes are also used in our backtester and in our core summarized data, there are many eyes on the quote files to ensure quality.
