The Chicago Board of Trade (CBOT(R)) and eSignal, a division of Interactive Data Corporation (NYSE: IDC), today announced CBOT Advantage Wireless - a real time solution for delivering streaming quotes, charts and market news to mobile devices. CBOT Advantage Wireless, available to new subscribers for free over a 30-day trial period, offers greater access and flexibility for users of the Exchange's market data. Product information is available at www.cbot.com/wireless. "Due to the ever-changing nature of our markets, CBOT market participants must be able to access the timeliest information as they make important decisions," said Steve Dickey, vice president of market data products at the CBOT. "CBOT Advantage Wireless is the ideal solution for participants seeking mobile connectivity to the market. It offers easy-to-use features and functionality and its screens are easy to follow." Compatible with many mobile devices including Palm-based Treo products, Blackberry devices, and HP's iPAQ product line, CBOT Advantage Wireless is available as a stand-alone solution, or as a companion to the existing browser-based CBOT Advantage product. "Because we had successfully launched CBOT Advantage in June 2003, it was an easy next step to join forces again to launch CBOT Advantage Wireless," said Chuck Thompson, president of eSignal. "Timing is essential in the futures market, and being anchored to a terminal or PC is not always possible. Now, CBOT market participants can track commodities and financial futures wirelessly, in real time." CBOT Advantage Wireless will be available on a stand-alone basis, including CBOT real-time market data, for $99.95 per month. The product will also be available for $24.95 as an add-on to CBOT Advantage Desktop. For more information on CBOT market data products, please visit www.cbot.com/marketdata.
