The New York Stock Exchange will close its exchanging floor and incidentally move to all electronic exchanging, NYSE President Stacey Cunningham declared on Wednesday.

The main equities exchanging floor will close down at 5:30 p.m. on Wednesday for extra cleansing after two individuals were tested positive for the coronavirus as a part of the trade’s clinical screening, Cunningham said.

“We have been informed that a member of the trading floor community and an NYSE employee have tested positive for COVID-19,” said Michael Blaugrund, the NYSE’s chief operating officer. “Both individuals were screened at the NYSE security checkpoint, administered a test by medical personnel at the Exchange and, as a precautionary measure, not permitted to enter the building this week. They will be treated and recuperate away from the Exchange facility.”

“While we are taking the precautionary step of closing the trading floors, we continue to firmly believe the markets should remain open and accessible to investors,” Cunningham said in a statement.
