CME是第一家关闭交易场所的，剩下的要看纽约交易中心怎么办了。如果纽约市长宣布Lock down，NTSE也会关闭他家的Trading floor。所有交易都改成幕后电子交易。 这对股市又是个很大的打击。
CME Group announced Wednesday night it will close its Chicago trading floor in a precautionary move due to the coronavirus outbreak.
The closing will take effect Friday “at the close of business,” CME said in a statement, noting that no coronavirus cases have been reported at the Chicago Board of Trade trading floor.
This would make CME the first major U.S. exchange to close a trading floor due to concerns over the coronavirus. The New York Stock Exchange is taking precautionary measures as well, working to separate traders and other employees, according to a Reuters report citing an internal memo.
