Hurricane Irene does not appear to have harmed the data centers in New Jersey where the exchanges operate.
The four main national exchange operators use computing facilities in Weehawken, Carteret, Secaucus and Mahwah, with backups in Nutley, Clifton and out of state.
NYSE Euronext said the New York Stock Exchange, NYSE Arca, NYSE Amex, NYSE Arca Options, NYSE Amex Options, and NYSE Liffe U.S. all would operate as usual.
This decision follows a detailed review with New York City and other officials of the operational readiness of metro-area safety, power, water, and transportation systems, in addition to a readiness assessment of our own trading and data center facilities, along with consultation with staff members, trading professionals, other exchanges, and regulators.
Direct Edge said technicians had inspected its systems at our primary data center facility in Secaucus, NJ.
There has been no damage and all systems are operating normally.
BATS Global Markets said the exchanges had consulted throughout the weekend with the Securities and Exchange Commission and " the decision was made by the exchanges and the SEC that all markets would open on time" today.
BATS said its data centers were unaffected by Irene.
The Securities Industry and Financial Markets Association said it is not recommending any changes to the trading of US dollar-denominated fixed-income securities in the United States on Monday, August 29, 2011.

This recommendation applies to trading of US dollar-denominated government securities, mortgage- and asset-backed securities, over-the-counter investment-grade and high-yield corporate bonds, municipal bonds and secondary money market trading in bankers’ acceptances, commercial paper and Yankee and Euro certificates of deposit.
