Paris, Amsterdam, Lisbon and Brussels exchanges – operating under NYSE‘s Euronext banner – were effectively forced offline by the problem, which began shortly after the start of trading at 9.07 am and was rectified at 11 am. The exchanges experienced similar problems Monday, though it is not known if the technical fault was the same.
The company said in a statement that it had experienced “latencies” on trading systems after opening the markets today.
NYSE Euronext is moving its matching engine technology over to its Universal Trading Platform, which is based on Red Hat Linux running on x86 servers. It is not clear whether this move or these systems played any part in the problems.
“Due to technical issues, the pre-opening phase for regulated equities and bonds andETFs [and] opening of the continuous trading session will be delayed,” NYSE Euronext told traders early this morning.
