Associated Press | The leaders for major securities exchanges have agreed in principle to a
uniform system of “circuit breakers” that would slow trading during
periods of intense market volatility, federal regulators said Monday.

The heads of the biggest exchanges “agreed on a structural
framework, to be refined over the next day,” Securities and Exchange
Commission Chairman Mary Schapiro said.

The
agreement has been reached by leaders of six exchanges, including the New York Stock Exchange and NASDAQ. The absence of
a uniform system is being looked at as a possible trigger for last
week’s historic stock market plunge.
