Notice
Summary
24X National Exchange is extending its post-market trading hours by one hour, now closing at 8 p.m. Eastern Time instead of 7 p.m. This change keeps a one-hour trading pause intact and updates related rules. Traders and investors get more time to buy and sell, with the new hours effective immediately—meaning more chances to make moves in the market!
Analyzed Economic Effects
6 provisions identified: 5 benefits, 1 costs, 0 mixed.
One Extra Hour to Trade After-Hours
If you trade or invest, 24X extends its Post-Market Session by one hour so it now closes at 8:00 p.m. Eastern Time instead of 7:00 p.m. Eastern Time. This extra hour to buy or sell NMS stocks will be available when 24X begins operations on September 29, 2025.
One-Hour Trading Pause Moved Later
24X preserves its one-hour Trading Pause but shifts the pause so it will run from 8:00 p.m. ET to 9:00 p.m. ET on Monday through Thursday nights that precede a U.S. Business Day. That hour will be a period with no trading on 24X.
NMS Stocks Still Tradable After-Hours
All NMS (national market system) stocks will continue to be eligible for trading during the revised Post-Market Session hours that end at 8:00 p.m. ET. The Exchange states this eligibility remains unchanged under the new hours.
After-Hours Risk Disclosures Continue
Broker-dealers (Members) must continue to give the required customer disclosures about the heightened risks of Pre-Market and Post-Market (extended hours) trading under Rule 3.21. Those disclosure obligations apply to the revised Post-Market Session hours that end at 8:00 p.m. ET.
Consolidated Quotes and Trades Available to 8pm
The Exchange will submit quotes and trades generated during the revised Post-Market Session to the Securities Information Processors (SIPs) for public dissemination, and the two SIP Plan Processors currently operate through 8:00 p.m. ET. Consolidated last sale and quotation information will be available through the extended Post-Market hours.
Rule Effective Upon Filing; Trading Starts
The Commission waived the 30-day operative delay and designated the proposed rule change operative upon filing (filed September 24, 2025), and 24X will begin trading on September 29, 2025 with the revised Post-Market hours. This makes the extended hours available immediately when 24X commences operations.
