The partial reopening will bring an end to the floor’s longest closure ever. It shut down more than two months ago on March 23 after some staffers tested positive for the deadly virus.

But only a handful of brokers will be allowed on the floor — and they’ll have to have their temperatures checked, wear face masks and follow social-distancing rules, NYSE president Stacey Cunningham has said. Most NYSE employees will continue working remotely and those who do commute to Wall Street must avoid public transportation, she said.

“The virus will remain a stubborn reality but we can’t keep the country closed indefinitely,” Cunningham wrote in a Wall Street Journal op-ed earlier this month. “Given that, our reopening will bring a ‘new normal’ for the NYSE, hopefully helping chart a path that other businesses in densely populated areas might follow.”

The NYSE kept trading going electronically as the coronavirus spread around the US and disrupted the global economy. Cunningham has said the Big Board won’t resume its regular schedule of events just yet — though some people were allowed on the floor during the closure for the initial public offering of a Chicago-based mutual fund, as The Post reported last month.
