Abstract generation in progress

The US stock market is about to undergo a historic turning point. According to BlockBeats, Nasdaq is preparing to submit an application to the (SEC) to implement a new trading model called 5X23.

What Is the 5X23 Model?

Unlike traditional trading systems, the 5X23 model will extend trading hours from 16 hours per day to 23 hours, five days a week. Not only will it apply to stocks, but exchange-traded products (ETPs) will also benefit from this change.

Two Main Trading Sessions Under the 5X23 Framework

The Nasdaq platform plans to divide trading time into two separate sessions:

Day Session: Operating from 4:00 AM to 8:00 PM Eastern Time. During this period, there will be three phases: pre-market trading (opening at 4:00), regular trading (from 9:30 AM to 4:00 PM), and after-hours trading (closing at 8:00 PM).

Night Session: Extending from 9:00 PM to 4:00 AM the next day. Trades made from 9:00 PM to midnight will be counted on the next trading day.

Extended Trading Week

With the 5X23 framework, the trading week will start earlier — from 9:00 PM on Sunday — and last until 8:00 PM on Friday after the main daytime trading session ends.

This strategic move by Nasdaq aims to enhance liquidity and seize global trading opportunities amid an increasingly 24/7 market environment.
