Seamless Two-Phase Trading: Day and Night Sessions with Just One Hour of Downtime

Paul Atkins, Chair of the U.S. Securities and Exchange Commission (SEC), recently revealed in an exclusive interview with Yahoo Finance that the SEC will begin exploring plans this fall to implement a new trading schedule for U.S. equities: five days a week, 23 hours a day.

According to Nasdaq's plan, the new system will be divided into two trading sessions: a daytime session and a nighttime session. The daytime session will run from 4:00 a.m. to 8:00 p.m. Eastern Time, while the nighttime session will continue from 9:00 p.m. to 4:00 a.m. the following day, with only a one-hour break from 8:00 p.m. to 9:00 p.m. This upgrade has already received SEC approval and is currently awaiting system upgrades from the Depository Trust & Clearing Corporation (DTCC) and the Securities Information Processors (SIP) to support clearing and nighttime operations.
