By John McCrank NEW YORK (Reuters) – The committee that oversees the data processor that was at the center of a three-hour trading halt in Nasdaq-listed stocks in August agreed on Thursday to implement fixes demanded by the exchange, according to a source familiar with the situation. Nasdaq OMX Group runs one SIP and two others are run by units of IntercontinentalExchange Incs NYSE Euronext. A software glitch crippled Nasdaqs SIP in August, forcing the exchange to halt trading on its listed stocks. U.S. Securities and Exchange Commission Chair Mary Jo White ordered the exchanges to come up with protocols to improve the resiliency of the processors.
