Nasdaq plans to change its trading model to a "23/5" system, allowing trading for 23 hours a day, five days a week. If approved by the SEC, this shift integrates day and night sessions, significantly increasing trading hours and opportunities for investors.

Abstract generation in progress

According to information from Jinse Finance, the Nasdaq stock exchange is preparing for a major milestone in the history of US stock trading. Next Monday, Nasdaq will submit a proposal to the (U.S. Securities and Exchange Commission) (SEC), requesting approval to implement an almost 24-hour trading model.

Changes from the old model to the 23/5 model

Currently, Nasdaq operates on a schedule of three separate trading sessions. The early session runs from 4:00 AM to 9:30 AM (Eastern Time). Next is the regular session from 9:30 AM to 4:00 PM. Finally, there is an evening trading session from 4:00 PM to 8:00 PM. In total, each trading day lasts only 16 hours over 5 days a week.

If approved by the SEC, Nasdaq will switch to the “23/5” model — meaning trading for 23 hours each day during the 5-day workweek. The trading schedule will then be reorganized into two main sessions: a daytime session from 4:00 AM to 8:00 PM, and a nighttime session operating from 9:00 PM to 4:00 AM the next day.

New trading session structure

In the daytime session under the new model, Nasdaq will still open with the bell at 9:30 AM and close at 4:00 PM. The early, regular, and evening sessions will be integrated into this daytime session. After the daytime session ends, there will be a one-hour maintenance window for system checks and transaction settlements.

The nighttime trading session will be the newest feature — operating continuously from 9:00 PM to 4:00 AM the following morning. An important detail is that trades executed between 9:00 PM and midnight will be recorded on the next trading day.

Impact on weekly trading schedule

According to Nasdaq’s plan, the trading week will start at 9:00 PM on Sunday and end at 8:00 PM on Friday after the daytime market session concludes. This means investors will have the opportunity to participate in trading for significantly longer periods than before, creating new opportunities but also requiring adaptations from the trading community.
