International Securities Exchange LLC said it is investigating an issue with market data on the ISE and Gemini exchanges, according to an e-mail sent to traders.
Options exchanges owned by Bats Global Markets Inc. and Nasdaq OMX Group Inc. were routing orders away from the venue. Molly McGregor, a spokeswoman for the ISE, didn’t return a call and an e-mail seeking comment.
The issue came a day after a data feed interruption prevented prices for Nasdaq OMX’s benchmark U.S. stock indexes from being disseminated for almost an hour.
