Blaugrund was speaking with NYSE employees, heads of firms and brokers on the 40-minute call. He said when the floor does open, there will be a reduced head count on the floor and social distancing guidelines will be followed, according to the two sources.
The same protocol that the NYSE followed just before the floor closed will also be in effect, meaning temperature checks for anyone entering the building, according to the sources.
Blaugrund said the NYSE Arca Options trading floor in San Francisco might reopen on May 3, the two sources said.
