CBOE Commemorates One Week Anniversary Of Snafu With New, Shorter Screw-Up

This is getting tiresome.

The Chicago Board Options Exchange suffered system problems early Thursday that affected trading in some stock-options contracts, a week after technical issues closed its markets for more than three hours.

The latest problems saw about 300 classes of stock options hosted on an exchange "business cluster" run by CBOE open for trade 10 minutes late Thursday, after the exchange reported problems ahead of the start of trading.

Some "spread" trading strategies were unavailable to investors until about half an hour after the start of trading, according to notices sent to traders by the exchange….

Traders on Thursday generally described the morning's issue as a nuisance, versus the large-scale breakdown last week.

Traders were notified of issues about 45 minutes before markets opened Thursday when CBOE sent a message saying that some of its customers were having problems with "product downloads." CBOE sent out a similar alert ahead of its outage last week.
