DOW JONES NEWSWIRES 
 

The New York Stock Exchange set the circuit-breaker thresholds for the third quarter.

The exchange first implemented the circuit breakers in the wake of the market's crash in October 1997. In 1998, the NYSE set the triggers at 10%, 20% and 30% declines in the Dow Jones Industrial Average for the three levels of halts.

A level 1 halt will stop trading for an hour if the Dow falls 850 points before 2 p.m. ET, or for 30 minutes if triggered between 2 p.m. and 2:30 p.m.

A second-level halt - in the event of a 1,700-point drop - will last two hours if it happens before 1 p.m., one hour if in the next hour, or for the rest of the day if after 2 p.m.

Finally, trading will end for the rest of the day, regardless of timing, if the DJIA falls 2,600 points.
