A technical glitch shut down an electronic order management system on the floor of the New York Stock Exchange (Nyse) for over fours hours yesterday, forcing some traders to handle trades on paper.
In a statement Nyse says its Broker Booth Support System (BBSS) - an order management system used to transfer data from handheld computers on the floor to trading booths - began experiencing technical problems at approximately 10:06am EST.
Customer orders had to be processed by floor brokers manually and through proprietary broker booth systems, which were unaffected by the problem, until the BBSS system came back online at 2:15pm EST.
Nyse says it has "fully resolved" technical issues related to the BBSS system.
Orders routed electronically through Nyse's CMS, SuperDot and Hybrid Market order routing systems were unaffected by the glitch.
