ISE Launches Historical Options Tick Data Offering(TM).

ISE HOT Data[TM] Meets Demand for Comprehensive Data Resource

NEW YORK -- The International Securities Exchange (NYSE: ISE) today announced the official launch of its Historical Options Tick Data[TM] offering (ISE HOT Data[TM]), the first in its suite of new market data products. The ISE HOT Data offering includes the full daily tick file of all trades and quotes for equity and index options that are reported to the Options Price Reporting Authority (OPRA). These comprehensive, historical data files will enable sophisticated investment professionals to conduct in-depth trade analyses, back-testing of trading models, and will serve as a data source for compliance requests and time and sales queries.

Historical options data has not previously been available as a complete, end-of-day file. Dr. David Reynolds, Chief Technology Officer of Quantlab Financial LLC, states, "We require complete and reliable data for our market analysis. Options market data is particularly challenging because of the extraordinary quote volume, but ISE met our needs by providing quick delivery of the OPRA data in the industry-standard format that is easily read by our data loader."

ISE currently provides two ISE HOT Data offerings to meet investor demands. The first product is an annual subscription to a daily end-of-day file that is accessible as a flat file from a FTP server over the Internet. The second offering provides flexibility to make ad-hoc requests for a specific range of dates. The ad-hoc requests will be processed and delivered on a portable hard-drive device which can be reused by the client. In an effort to make this data accessible and cost-effective, both offerings are delivered as compressed files to reduce necessary bandwidth requirements.

ISE HOT Data is an important component of ISE's ongoing initiative to expand its Information and Market Data business. Two additional products, an enhanced version of the ISE Sentiment Index[R] (ISEE[R]) and Depth of Market Data, are slated to launch in the coming weeks.
