Included Data
NYSE OpenBook provides a real-time view of the Exchange's limit-order book for all NYSE-traded securities. NYSE OpenBook lets traders see aggregate limit-order volume at every bid and offer price. The data is dynamically updated all day between 7:30am and 4:30pm. The datafeed is available via SFTI multicast feed in PDP Binary Format.
History: 2 Jun 2008 - present

A tcpdump capture file of an entire day's distribution is available for download at this location:

ftp://sampledata:datacap@ftp2.nyxdata.com/custom/

Typically the file contains the entire record of packets sent over a datafeed multicast group for a day, including start-of-day and end-of-day messages.  In some cases we have capture multiple channels in addition to refresh channels.
The Real-Time NYSE Quotes feed provides NYSE Quotes (best bid/ask quotations) for all NYSE-traded securities as part of the NYSE OpenBook product offering. For no additional fees, customers of NYSE OpenBook can choose to receive the NYSE Best Quote directly from NYSE rather than through the Consolidated Quotation System (CQS). This means that firms will be provided a complete liquidity picture containing both depth of book and best market quote interest directly and more efficiently than ever before. The NYSE best market quote differs from top of book information in that it contains not only limit orders on the book but specialist and Floor broker interest that is not on the book.
The NYSE Imbalance datafeed is a separate datafeed which publishes Opening and Closing imbalances automatically at specified intervals throughout the trading day for all NYSE listed securities.

Frequently Asked Questions
  • What is NYSE OpenBook Real-Time?
    The product provides a real-time view – aggregated and refreshed every second – of the New York Stock Exchange’s limit-order book for all NYSE-traded issues. NYSE OpenBook Real-Time lets traders see aggregate limit-order volume at every bid and offer price, thus responding to customer demand for depth-of-market data and raising the NYSE market to an even greater level of transparency.
  • Why not refresh NYSE OpenBook with every single order or cancellation?
    Many customers prefer that data be aggregated at every price level, which they see as more significant information than a flickering stream of smaller changes. NYSE Group will continue to evaluate this and other products to ensure they are responsive to customer demand.
  • Will NYSE OpenBook Real-Time data be commingled with other markets’ data?
    Data vendors may choose to commingle NYSE data with that of other markets. However, vendors will be required to ensure that investors have easy access to displays that readily identify the NYSE as the source of the information.
  • Is the “top of book” bid and offer in OpenBook the same as the NYSE’s best bid and offer?
    The best bid and offer in OpenBook represents only the limit orders on the specialist’s book and not the entire market. The NYSE best bid and offer may also include market orders, crowd interest, or specialist proprietary interest. These bids or offers may be, in fact, better than those bids and offers contained on the Book.
  • Why is it that the opening price may be different than what OpenBook information indicates it should be?
    Limit orders and market orders often accumulate between the previous night’s close and the opening. In some cases, market orders comprise the majority of pre-opening interest, and market order imbalances become the key determinant of where a stock will open. Because OpenBook does not contain market orders, it may not be indicative of the entire pre-opening interest.
  • Can a bid price in OpenBook ever be equal to (locked market) or greater than (crossed market) an offer price, and vice-versa?
    Bids that are entered at or higher than offer prices will be reflected on the book until they are executed. The same is true for offers entered at or lower than bids. NYSE market rules treat these “marketable limits” as market orders, and they are executed as market orders according to NYSE auction market rules. Locked and crossed markets are typically short-term situations that are corrected by a subsequent trade. Locked or crossed markets occur more often in very active and volatile stocks. The implementation of the NYSE Hybrid Market is expected to increase the amount of automated trade executions, which may in turn significantly decrease the instances of crossed markets on OpenBook.
