Just caught wind of something pretty significant in the traditional finance space. Nasdaq is making moves to push a pretty ambitious proposal to the SEC—they're looking to basically revolutionize how stock trading works with what they're calling the 5X23 model.

Here's the gist: instead of the current setup where you can trade stocks and ETPs five days a week for 16 hours, Nasdaq wants to stretch that to 23 hours daily. Basically, they're trying to create a nearly round-the-clock trading environment.

The structure would split into two main windows. During the day, trading kicks off at 4 a.m. Eastern and runs until 8 p.m., keeping the familiar pre-market, regular hours (9:30 a.m. to 4 p.m.), and after-hours sessions intact. Then there's the night session from 9 p.m. to 4 a.m. the next morning. Anything you trade between 9 p.m. and midnight gets marked as the following day's activity.

What's interesting about the 5X23 framework is how it redefines the trading week. Under this new schedule, your week would start Sunday at 9 p.m. and wrap up Friday at 8 p.m. after the daytime close. It's a pretty significant shift from the traditional Monday-to-Friday mentality.

If this goes through, it could be a game-changer for how people approach equity trading. More hours means more flexibility, though it also means more pressure on traders to stay on top of things. Curious to see how the market reacts if the SEC actually approves this.
