In a quick turnaround with plenty of notification to the press, Nasdaq OMX announced that it has restores trading to one the exchange groups three U.S. options markets, NASDAQ Options Market (NOM).
According to Nasdaq, “At approximately 11:42:43 a.m. ET, NASDAQ OMX experienced an issue processing OPRA data that affects one of the exchange groups three U.S. options markets, NASDAQ Options Market (NOM), for trading in symbols A-M. We have worked diligently to restore normal operations and trading has resumed in those symbols since 12:00:00 p.m. ET.”
This is a big difference when the market maker experienced a three-hour trading glitch in August. Back then, the exchange gave very few updates on the trading outage and CEO Bob Greifled did not address the media until the next day.
Today, the exchange’s message included this statement: “The reliability of our market systems is essential to our ability to provide a fair and efficient trading environment for our clients and other market participants. We have committed our full resources to identify the root cause of this U.S. options data issue was a NOM hardware fail-over related to inbound OPRA quote data from other U.S. options exchanges in symbols A through M. All systems are operating normally.”
