Several U.S. stock-options exchanges halted trading Monday afternoon due to a problem with the baseline data feed supplying options prices to traders.
Exchanges run by Nasdaq OMX Group Inc. (NDAQ), BATS Global Markets Inc. and Miami International Holdings told traders via electronic notices that their markets were halting due to problems with the Options Price Reporting Authority, or OPRA, which provides information on trades and quotes.
The glitch follows a nearly three-hour shutdown last month of all trading in Nasdaq-listed securities due to a problem with the data feed handling those prices.
Exchange executives and regulators met last week in Washington, D.C., to discuss ways to make such data feeds more resilient to outages.
