Nasdaq Plans to Launch Night Trading Session in December
Nasdaq plans to launch a night trading session on December 6, from 9 PM to 4 AM Eastern Time.
This move will extend trading hours to 23 hours a day, five days a week, with a one-hour pause for system maintenance from 8 PM to 9 PM daily.
The plan is still subject to the readiness of the securities information processor and final approval from the SEC.
The night session will support routable orders, but certain types such as market orders will not be available, and a price protection band will be set.
The main prices will still be determined through the opening and closing cross in regular trading hours.
Market mechanisms will extend event-driven liquidity of U.S. stocks to global time zones: funds and order flows will directly access from markets like Asia, with exchanges and brokers competing for night liquidity, while traditional after-hours and ATS shares face redistribution.
Additionally, the related LULD price protection mechanism will take effect on the same day.

Nasdaq's push for near-around-the-clock trading reflects the global investors' demand for continuous access to U.S. stocks outweighing traditional time zone limitations.
In terms of capital pathways, the investment in night infrastructure and data systems aims to capture order flows during the Asian daytime, strengthening the position of U.S. exchanges as global pricing centers.
Similar cases can be seen in the impact of 24/7 trading in the crypto market on traditional finance, as well as overnight trading services already offered by some brokers; currently, exchanges are transitioning from 16-hour to 23-hour trading.
The structural judgment belongs to the reconstruction of the industry chain: the restructuring of trading hours changes the rhythm of liquidity supply and risk pricing, with the mechanism aimed at eliminating time zone friction, allowing capital to allocate U.S. stock assets instantly in any time zone.
