Another day, another disruption in the plumbing of US markets.
Options trading in the US was briefly halted on Monday after the Options Price Reporting Authority suffered a systems issue.
The issue triggered a halt in trading of options at Nasdaq, the Chicago Board of Options Exchange (CBOE), Bats and NYSE Euronext. It comes just weeks after a computer issue caused the Nasdaq to halt equity trading for more than three hours.
In an alert sent to traders, the CBOE said an "OPRA Data issue" had forced it to stop trading. OPRA is managed by the Securities Industry Automation Corporation which is made up of a number of US exchanges and managed by the NYSE Euronext. OPRA provides live quotes and prices for options trading.
Last week, the US Securities and Exchange Commission held a meeting with exchange operators over the recent run of trading outages.
