So, you're looking at the clock and wondering if you still have time to squeeze in one last trade. It happens to the best of us. Whether you’re trying to catch a late-day rally or just trying to offload a position that’s been nagging at you all afternoon, knowing exactly how late is the stock market open today is the difference between a successful execution and a "rejected" order notification.
Today is Thursday, January 15, 2026. If you are trading on the major U.S. exchanges like the NYSE (New York Stock Exchange) or Nasdaq, the short answer is that the "core" session ends at 4:00 p.m. ET.

But honestly? That’s only half the story. The markets never really "sleep" anymore in the way they used to back in the 90s. Between pre-market sessions, the closing auction, and the wild world of after-hours trading, the "closing bell" is more of a suggestion than a hard stop for most modern retail traders.
The Standard Hours: When the Big Money Moves
For the vast majority of investors, the most important window is the core trading session. This is when liquidity is highest, spreads are tightest, and the "big boys" (institutional investors and hedge funds) are doing their heavy lifting.
- 9:30 a.m. ET: The opening bell rings.
- 4:00 p.m. ET: The closing bell rings.
If you’re on the West Coast, you’ve probably already realized this means your trading day basically ends while you're thinking about lunch. For folks in California, that’s 6:30 a.m. to 1:00 p.m. PT.
It’s worth noting that today, January 15, is a standard trading day in the United States. We aren't hitting a federal holiday—Martin Luther King Jr. Day isn't until this coming Monday, January 19, 2026. On that day, the markets will be completely shuttered. But today? It's business as usual.
After-Hours: How Late Can You Actually Trade?
This is where things get interesting—and a bit risky. Most brokers, including Schwab, Fidelity, and Robinhood, allow you to trade well after the 4:00 p.m. bell.
The after-hours session typically runs from 4:00 p.m. to 8:00 p.m. ET.
Why would you do this? Usually, it's because a company just dropped an earnings report or some massive geopolitical news hit the wires. If you wait until 9:30 a.m. tomorrow, the price might have already moved 10% against you.
However, trading late at night isn't for the faint of heart. Liquidity dries up. You'll see "spreads" (the difference between what a buyer will pay and a seller will accept) get massive. One minute a stock is at $150, the next it’s at $142 because there just aren't enough people trading to keep the price stable.
A Quick Word on Global Markets
If you happen to be looking at international exchanges today, the vibe is a bit different. For instance, the Indian markets (NSE and BSE) are actually closed today, January 15, 2026, because of the Maharashtra civic body elections. It’s a good reminder that just because Wall Street is humming along doesn't mean the rest of the world is.

The Closing Auction: The Final 10-Minute Sprint
Most people think the price you see at 4:00 p.m. is just the last trade that happened. Not exactly.
The NYSE and Nasdaq use something called a "Closing Auction." Around 3:50 p.m. ET, the exchanges start "freezing" certain types of orders to determine a single, fair price that balances out all the buying and selling interest at the very end of the day. This is often when the highest volume of the entire day occurs.
If you’re trying to buy at the "closing price," you're actually participating in a highly complex mathematical algorithm that concludes right at the stroke of 4:00 p.m.
24/5 Trading: The New Frontier in 2026
We're currently in a bit of a transition period for market hours. You might have heard that Nasdaq has been pushing for a "Night Session" that would basically allow for 23-hour trading on weekdays.
While that’s still winding its way through regulatory approvals and infrastructure tests (the DTCC is eyeing mid-2026 for full 24/5 clearing support), many retail platforms already offer a version of this.

- Robinhood’s 24 Hour Market: Allows trading on select ETFs and stocks from Sunday 8:00 p.m. through Friday 8:00 p.m. ET.
- Interactive Brokers: Also has an overnight session for certain US stocks and ETFs.
Basically, if you’re using a modern app, "how late is the stock market open" depends less on the NYSE and more on what your specific broker allows.
Actionable Tips for Late-Day Trading
If you’re planning on trading near the close or in the after-hours session today, keep these three rules in mind:
- Use Limit Orders: Never, ever use a "Market Order" after 4:00 p.m. Since there are fewer traders, a market order could get filled at a disastrous price. A limit order ensures you only buy or sell at the price you actually want.
- Watch the Volume: If you see a stock jumping 5% at 5:30 p.m. on only 100 shares of volume, ignore it. It’s noise. Wait for the "real" moves backed by thousands of shares.
- Mind the Calendar: Remember that today is the "calm before the storm." With a long weekend coming up (the market is closed Monday), many traders might start closing out their positions early tomorrow (Friday) to avoid "weekend risk."
The clock is ticking. If you're looking for the standard "bell," you have until 4:00 p.m. ET. If you're okay with a little extra volatility, your platform probably gives you until 8:00 p.m. ET to make your move.
Next Steps for You:
Check your specific brokerage settings to see if you have "Extended Hours" enabled. Some brokers require you to sign a waiver or toggle a switch in your settings before they'll let you trade past 4:00 p.m. If you're planning a late move today, make sure that's ready to go before the closing bell rings.
