Nasdaq reports another problem with its data feed

CNBC

The Nasdaq (NDAQ) had yet another problem with the main data feed that was at the center of the outage that brought trading in Nasdaq securities to a halt for about three hours nearly two weeks ago.

According to the exchange, a system called the "Securities Information Processor," or SIP, experienced an outage between 11:35 a.m. and 11:41 a.m.

The outage affected the exchange's ability to transmit quotes in stock symbols PC through SPZ.

But other market participants said the outage was worse than that. NYSE Arca said it stopped receiving inbound stock quotes on all Nasdaq symbols between 11:35 a.m. ET and 11:44 a.m. ET.

The problem has been resolved, Nasdaq said, and trading was not impacted.

"The system successfully failed over and is operating normally," the exchange said in a 12:32 p.m. ET email.

A Securities and Exchange Commission spokesman said the agency is in contact with the Nasdaq and is monitoring developments related to the data feed problem.
