ISE Statement on OPRA Market Data Issue

NEW YORK, October 30, 2013 -- The International Securities Exchange (ISE) experienced a technical issue that led to a disruption in its outbound market data feed to OPRA commencing at the market open through approximately 10:55 am. The root cause has been identified as a configuration error on the OPRA side that they applied specifically to the communication lines dedicated to receiving data from ISE and ISE Gemini. After implementing a temporary work-around to resolve the issue this morning, ISE and OPRA technology teams are collaborating to restore the proper configuration.
