All products will continue to trade on CME Globex as they do today.
No coronavirus cases have been reported on the trading floor or in the Chicago Board of Trade building. The reopening of the trading floor will be evaluated as more medical guidance on the coronavirus becomes available. The company's headquarters at 20 S. Wacker Drive will remain open.
The trading floor community will receive an additional q&a related to the execution of certain floor products, procedures and protocols and other floor-related practices.
