The startup, 24 Exchange, said it filed key parts of its application for a national stock-exchange license with the SEC on Monday, including a rulebook and user manual detailing its proposed approach to trading hours.
Under decades-old conventions, the bulk of stock trading takes place between 9:30 a.m. and 4 p.m. ET on weekdays, and exchanges shut down for holidays, such as Good Friday and Washington’s Birthday. In contrast, 24 Exchange would operate like the foreign-exchange and cryptocurrency markets, which run continuously.
