The New York Stock Exchange Launches NYSE OpenBook Real-Time®

The New York Stock Exchange today launched NYSE OpenBook Real-Time^® , an information tool for investors and market professionals designed to offer customers immediate access to market information, increase the transparency of the NYSE market, and support the implementation of the NYSE Hybrid Market^SM.

OpenBook Real-Time offers a valuable snapshot of the NYSE market and its unparalleled liquidity by providing a real-time view - aggregated and refreshed every second - of the NYSE's limit order book for all NYSE-traded issues. By giving customers instant access to aggregate limit-order volume at every bid and offer price, OpenBook Real-Time provides faster, more transparent information about NYSE liquidity.

Complementing the speed and flexibility of the Hybrid Market platform, NYSE OpenBook Real-Time responds to customer demand for depth-of-market data and will coexist alongside the original 5-second OpenBook^® product that is currently available.
