New web page provides ongoing latency transparency

New York, March 13, 2012 – The International Securities Exchange (ISE) announced that current median latency for its Optimise™ trading system equals 250 microseconds. This represents a reduction of approximately 39% since the completion of the Optimise rollout in August 2011. Significantly, ISE has reduced the latency tail so that 90% of all quotes submitted to the system are acknowledged within 340 microseconds, representing a 45% reduction in the past six months.

ISE is also now publishing its latency statistics for Optimise on a new, dedicated webpage, www.ise.com/latencystats . The latest statistics are measured and reported via the CorvilNet performance monitoring solution, which was implemented in February 2012. As part of ISE’s commitment to continually enhance its leading technology platform, the statistics will be updated approximately every two months, following each new technology release.

Daniel Friel, ISE’s Chief Information Officer, said, “We were extremely proud of the enormous improvement in ISE’s latency profile when we completed the rollout of Optimise last August. Since implementation of the initial Optimise release, our technology team has remained solidly focused on continuing to improve the system’s performance and implementing cutting-edge technology solutions to lower latency. With a median latency figure of 250 microseconds combined with its industry-leading functionality, Optimise is at the forefront of options trading platforms globally.”
