NASDAQ, NASDAQ BX, and NASDAQ PSX would like to advise their customers of an issue that took place earlier today. Because of an internal issue, all three markets would not have protected the New York Stock Exchange (N) quote from 09:30:00 ET until the issue was resolved at 09:40 ET. As a result, it is possible that some orders could have traded through, or not have been routed to, the NYSE quote when it was at the inside.
