The ISE Order Feed notifies subscribers when a new order is placed on ISE's order book, and it shows the size of the individual orders that comprise the Best Bid and Offer (BBO) on the exchange.

"We are very excited to launch the ISE Order Feed, which provides subscribers with a real-time snapshot of orders that are not immediately executed at the BBO and hence are resting on ISE's order book. Subscribers will have access to information about the size of the individual orders that comprise ISE's BBO, rather than only aggregated order information," said Jeff Soule, Head of ISE's Market Data business. "The new data feed does not include any quotes, and, therefore, requires less bandwidth and processing overhead than the Options Price Reporting Authority (OPRA) feed. This feature makes the ISE Order Feed an attractive product for those customers that are only interested in order flow information."

The ISE Order Feed is the latest offering in ISE's suite of market data products. Also available are the ISE Depth of Market Feed, ISE TOP Quote Feed, ISE Spread Book Feed, as well as put/call product offerings and historical market data.
