NYSE, Nasdaq, BATS and other exchanges reported issues with price and trading data Thursday afternoon, due to market-wide glitch at a key piece of market infrastructure that consolidates quotes and trading data.
The issue was with the SIP, the Security Information Processor, for stocks listed on the New York Stock Exchange. NYSE alerted "market-wide issues" between 1:40 p.m. ET and 1:50 p.m. ET, later reporting a hardware failure affected three of its data feeds from 1:07 p.m. ET to 1:34 p.m. ET.
According to an alert on BATS Exchange, the NYSE shifted operations to its disaster recovery site in Chicago. The outage was reportedly caused by problems at the exchange data center in Mahwah.
NYSE said it would restore normal operations at the primary data center for Friday trading.
Other exchanges reported problems after 1:50 p.m. when the systems were reconnecting. BATS trading desk reported no problems matching order but there were problems seeing what was on the tape. BATS declared operations normal at 2:10 p.m.
Options exchanges, like CBOE and Nasdaq OMX PHLX (Philadelphia exchange), were also affected because the issues affected Options Price Reporting Authority. OPRA provides last sale information and current options quotes to the 12 options exchanges.
The technical glitches coincided with a move up in the stock market, and traders said the coincidence which resulted in temporary spikes in some individual stocks, were later reversed. Traders also saw a coincidental jump in eMini S&P 500 prices and volume.
The Nasdaq blamed its August 2013 "flash freeze" on a problem with the SIP, which affected trading for an entire afternoon.
