They changed the Circuit Breaker from -250 to -350 on the Dow... Circuit breakers afffect trading on the New York Stock Exchange (NYSE) and the Chicago Board Options Exchange (CBOE) where S&P 500 futures contracts are traded. These are the provisions: Trigger: DJIA +/- 50 This is known as "Rule 80A". If this trigger occurs, program trading curbs are put in effect. Essentially a key computer is turned off, so program trading must be done "by hand". Curbs are removed when the DJIA retraces it's gain/loss to the +/- 25 level. Trigger: S&P 500 futures +/- 12 This is known as the "Sidecar" rule. If this trigger occurs, trading of the S&P 500 futures contract is suspended for 30 minutes, which effectively stops program trading. Trigger: DJIA +/- 350 This is known as "Rule 80B". If this trigger occurs, the NYSE halts trading for 30 minutes. Trigger: DJIA +/- 550 Also a provision of Rule 80B; if this trigger occurs, the NYSE halts trading for 60 minutes. Alex
