Computer glitches have hit trading in Nyse Euronext's European markets for the second successive morning.
Yesterday a "technical issue" resulted in a one hour delay to the opening of trading in equities, bonds and exchange-traded funds, hitting Paris, Amsterdam, Lisbon and Brussels.
This morning latency problems left members unable to enter, modify or cancel orders in some trading groups. This forced the operator to put back pre-opening mode for the affected groups to 10.30am CET, with trading back up and running by 11.00am CET.
Nyse Euronext believes the outage is related to the delayed opening in trading experienced on Monday.
"Following the incident experienced on Monday, thorough diagnosis and investigations were put in place to indentify the root cause of the instabilities observed within the trading architecture," says the exchange in a statement. "Risk mitigation and architecture changes will be implemented tonight, inclusive of alternative path connection in the network architecture and hardware replacements where appropriate."
