The Stock Market Is About to Stop Sleeping: 23-Hour Trading Is Coming
What 23-Hour Trading Could Mean for Everyday Workers, Traders, and Boom Stalker
By Steven Zapf | Founder, Zapf Technologies LLC | Creator of Boom Stalker
For millions of shift workers, the market’s traditional schedule has never matched the hours they actually live and work.
Following the stock market during its current schedule can sometimes feel damn near impossible when you work 12 or even 16-hour days.
I do my best.
Depending on what shift I am working, that might mean waking up early, staying up late, checking the market before work, or trying to catch up after a shift when my brain has already decided it is done participating for the day.
It gets exhausting.
Now imagine a stock market that works around your schedule.
In a way, that is exactly what is coming.
Nasdaq plans to introduce a new overnight trading session from 9:00 p.m. to 4:00 a.m. Eastern Time beginning December 6, 2026, moving the exchange toward trading 23 hours a day, five days a week. The SEC approved Nasdaq's extended-hours rule change in April.
The stock market is about to stop sleeping.
The question is whether the rest of us should try to keep up with it.
Wait, The Market Is Really Going to Trade 23 Hours a Day?
Yep.
Most people think of the stock market as opening at 9:30 a.m. and closing at 4:00 p.m. Eastern Time.
Nasdaq already operates premarket and post-market sessions, but the new overnight session fills most of the remaining gap. Nasdaq currently operates premarket from 4:00 a.m. to 9:30 a.m., regular trading from 9:30 a.m. to 4:00 p.m., and post-market trading until 8:00 p.m.
Beginning in December, the new session is scheduled to run from 9:00 p.m. until 4:00 a.m.
That gets us pretty damn close to a market that never closes during the workweek.
Nasdaq says part of the motivation is increasing global demand for access to U.S. equities.
Money apparently did not get the memo that everyone in New York went to bed.
The 9:30 to 4:00 Market Wasn't Built Around Everyone
If you are reading Boom Stalker, I imagine there is a decent chance you are like me.
You work.
Maybe you are in a plant. Maybe you are a nurse, truck driver, construction worker, first responder, warehouse employee, or one of the millions of people whose schedule does not remotely resemble 9 to 5.
And if you are reading this at 2:00 in the morning, then I know you are really like me. 😂
You are trying to get the most out of whatever little free time you actually have.
I work rotating shifts in a steel mill. Sometimes the market opens while I am working. Sometimes it opens while I should be sleeping.
Sometimes my schedule appears to have been created by someone with a personal grudge against circadian rhythms.
A nearly 23-hour market changes that equation.
Someone getting home from second shift may have access to a live market.
Someone awake before an early shift may have access.
Night-shift workers may suddenly have an active market during the same hours they are normally awake.
For working people, that is pretty damn interesting.
More Trading Hours Does Not Mean Easier Money
Here is where everybody needs to calm down a little.
A market being open longer does not mean there will suddenly be 23 straight hours of amazing trades waiting for us.
Overnight trading can come with different conditions than the normal trading day.
Liquidity may be thinner.
Bid-ask spreads may be wider.
Volume may behave differently.
And a price move at 2:15 a.m. may not carry the same information as a similar move at 10:15 a.m.
More access creates more opportunity to research.
It also creates more opportunities to do something stupid.
If you just finished a 16-hour shift and can barely remember where you parked, the fact that the market is open does not necessarily mean it is finally time to become a day trader. 😂
Access and opportunity are not the same thing.
The Market Can Stay Awake. You Should Probably Sleep.
This may be the part that interests me most.
The solution to a 23-hour market cannot be:
Watch the market for 23 hours.
That would be insane.
Most of us already have jobs, families, responsibilities, and approximately 47 other things fighting for our attention.
If anything, longer market hours make good research tools and automation more important, not less.
Nobody should need to monitor thousands of stocks around the clock just to figure out whether something unusual is happening.
Software can handle repetitive monitoring considerably better than a tired steelworker staring at a phone at 3:00 a.m.
Trust me.
I have thoroughly tested the second method. 😂
The market may be moving at 2:00 a.m. That does not mean you need to be.
What Does This Mean for Boom Stalker?
This is where things get especially interesting for me.
Boom Stalker exists partly because I do not have unlimited time to watch the market.
The original problem was pretty simple:
There is too much market information and not enough time.
Boom Stalker is being built to quiet some of that noise and organize price, momentum, volume, trend, relative strength, market context, and risk information into signals that deserve a closer look.
A market that barely closes makes that problem bigger.
It also creates some fascinating questions.
How should volume be measured when trading nearly never stops?
Should overnight volume be compared with regular-session volume?
Does momentum developing at 1:00 a.m. mean the same thing as momentum developing after the opening bell?
How should relative volume work?
Should overnight, premarket, regular-hours, and after-hours behavior be treated as separate environments?
And what kind of move is important enough that somebody actually needs to know about it?
Preferably without Boom Stalker waking me up every time some small-cap stock decides to lose its mind at 2:43 a.m.
That would be appreciated.
We Don't Know All the Answers Yet
And I'm perfectly comfortable saying that.
Boom Stalker is still being built and tested.
We are collecting data, running simulated trades, auditing what happens, finding problems, making improvements, and trying to understand what actually works.
Twenty-three-hour trading will create another environment that eventually needs to be studied.
I don't want to simply assume that rules built around normal market hours will behave exactly the same way overnight.
We'll quantify it.
We'll test it.
We'll probably break something.
Then we'll figure out why we broke it.
Pretty standard Boom Stalker development process at this point.
Maybe the Future Isn't Trading More
When people hear 23-hour stock market, the obvious thought is:
More time to trade.
I think the more interesting possibility may be the opposite.
Less time watching.
If markets are going to move while we are working, sleeping, spending time with family, or doing literally anything besides staring at charts, our tools need to become better at separating meaningful information from noise.
Especially for working people.
You shouldn't need a Wall Street job to understand what is happening in the market.
You shouldn't need six monitors.
And you definitely shouldn't need to spend every waking hour looking for the next move.
The market may be about to stop sleeping.
That doesn't mean we should.
The Shift Is Coming
Nasdaq's move toward 23-hour trading is about more than simply adding another trading session.
It changes when stocks can react.
It changes how traders may eventually think about volume, momentum, liquidity, and market sessions.
And for millions of people whose workdays have never fit neatly between 9:30 and 4:00, it could make the market a little more accessible.
There will be chaos.
There will be noise.
And there will almost certainly be somebody buying a terrible stock at 3:47 in the morning because a stranger online posted six rocket emojis.
Some things never change. 😂
Our job remains the same.
Understand what is actually happening.
Separate information from noise.
Define the risk.
And make better decisions with the time we have.
Because whether the market trades for six and a half hours or twenty-three, more information is only useful if we can make sense of it.
