5 Critical Secrets To Master Webull 24-Hour Trading In 2025 (Don't Trade Without This)

The financial landscape has fundamentally changed. As of late 2025, Webull’s 24-hour trading feature—officially known as 24/5 Overnight Trading—offers retail investors unprecedented access to the US stock market, allowing you to react to global news and earnings reports in real-time, even outside the traditional 9:30 am to 4:00 pm ET window.

This round-the-clock opportunity, however, is not without its complexities and risks. To truly master this feature, you must understand the critical limitations, especially concerning order types and market dynamics, to protect your capital while maximizing your flexibility.

The Complete Breakdown of Webull’s 24/5 Trading Schedule and Sessions

Webull’s 24-hour trading is not a single, continuous session, but rather a seamless transition between four distinct market periods that cover the entire 24-hour cycle, five days a week. This structure allows trading to occur from Sunday evening through Friday evening.

The entire 24/5 trading window runs from Sunday at 8:00 pm ET to Friday at 8:00 pm ET.

Here is the breakdown of the four sessions that constitute the full trading day:

  • Overnight Session: 8:00 pm ET to 4:00 am ET (Sunday through Thursday). This is the newest session that enables true 24-hour access.
  • Pre-Market Session: 4:00 am ET to 9:30 am ET (Monday through Friday).
  • Regular Market Session: 9:30 am ET to 4:00 pm ET (Monday through Friday).
  • After-Hours Session: 4:00 pm ET to 8:00 pm ET (Monday through Friday).

Understanding these timeframes is essential, as the rules and risks change dramatically between the Regular Market and the combined Extended Hours (Pre-Market, After-Hours, and Overnight).

Critical Secret #1: Only Limit Orders Are Supported During Overnight Trading

This is arguably the most important rule for any trader utilizing Webull’s 24-hour feature. During the crucial Overnight Session (8:00 pm ET to 4:00 am ET), Webull strictly limits the order types you can place.

You can only use Limit Orders.

This restriction is a safety mechanism designed to protect traders from the extreme volatility and lack of liquidity common during off-hours. A Limit Order guarantees a specific price or better, ensuring you do not get an unexpected execution at a wildly unfavorable price.

The following order types are not available during the Overnight Session:

  • Market Orders
  • Stop Orders
  • Stop Limit Orders
  • Trailing Stop Orders

For the other Extended Hours (Pre-Market and After-Hours), you may have access to a broader range of order types, but the Overnight session is strictly Limit Orders only. This is a key detail that separates Webull's 24-hour feature from its standard extended hours trading.

Critical Secret #2: The Hidden Costs of $0 Commission Trading

Webull proudly advertises $0 commission trading for US-listed stocks and ETFs, and this zero-commission policy extends directly to the 24-hour trading environment. This means you will not pay a direct brokerage fee to Webull for executing a trade, even at 3:00 am ET.

However, the hidden cost lies in the bid-ask spread.

During the Regular Market Session, millions of traders and institutions ensure high liquidity, which keeps the bid-ask spread (the difference between the highest price a buyer will pay and the lowest price a seller will accept) very tight.

During the Overnight Session, liquidity is significantly lower due to fewer participants. This lower liquidity causes the bid-ask spread to widen, sometimes dramatically. A wider spread means that the effective cost of your trade—the difference between the price you buy at and the price you could immediately sell at—is higher, even with zero commission.

Critical Secret #3: Navigating the Liquidity and Volatility Risks

The primary reason for the Limit Order restriction is the heightened risk profile of the Overnight Session. Any investor engaging in 24-hour trading must be acutely aware of these factors:

Lower Liquidity

Liquidity refers to how easily a security can be bought or sold without affecting its price. Outside of regular hours, fewer market makers and institutional investors are active. This lower liquidity means:

  • Large orders can be difficult to fill.
  • Small orders can have a disproportionate impact on the stock price.
  • Your Limit Orders may take much longer to execute, or may not execute at all.

Increased Volatility

Because of low liquidity, stock prices can experience rapid and significant swings based on minimal trading volume. A single news headline, an unexpected earnings announcement, or a large block trade can cause a stock to jump or plummet instantly. This is why a Market Order—which executes immediately at the next available price—is banned during this session, as it could lead to a massive loss.

Critical Secret #4: Eligible Assets and Account Restrictions

Webull's 24/5 Overnight Trading is not available for all assets or all account types. Knowing these limitations is key to ensuring your trade executes as planned.

Eligible Securities

The 24-hour trading is only available for a select list of US-listed stocks and ETFs. These are typically large-cap, highly liquid securities that Webull and its execution partners deem stable enough for off-hours trading. To view the official, up-to-date list of tradable stocks, you must log into the Webull app and navigate to "Menu - More - Trading - 24H Market."

Whole Shares Only

During the Overnight Session, you can only trade whole shares. Fractional shares, which are popular with new investors, are not supported for 24-hour trading. This means you must buy or sell in increments of one share (1, 2, 10, etc.).

Margin Trading is Not Supported

You cannot utilize margin trading privileges during the Overnight Session. All trades must be executed using your available cash balance. This restriction further reduces the overall risk exposure for both the brokerage and the investor during volatile off-hours.

Critical Secret #5: How to Maximize Your Advantage with Webull’s 24-Hour Access

For the informed investor, Webull's 24/5 trading feature offers significant strategic advantages, especially in the current dynamic market environment of 2025.

1. React to Global News and Earnings

Global financial markets operate continuously. A major economic announcement from Asia or Europe, or an earnings report from a US-listed company released after 8:00 pm ET, can immediately affect stock prices. 24-hour trading allows you to enter or exit a position *before* the US market formally opens the next morning, giving you a crucial head start.

2. Execute Price-Sensitive Limit Orders

Since you are restricted to Limit Orders, use this to your advantage. If a stock you want to buy is trading at $100, but you believe the low liquidity might briefly push the price down to $98 overnight, you can place a Limit Order at $98. If the brief dip occurs, your order will fill, and you will have secured a better entry price than you would have during regular hours.

3. Manage Time Zone Differences

For traders outside the Eastern Time Zone—particularly those in APAC or European markets—the 24/5 feature eliminates the need to wake up at odd hours to participate in the US stock market. You can manage your portfolio on a schedule that aligns with your local day.

By understanding the four distinct trading sessions, the crucial Limit Order restriction, and the inherent risks of lower liquidity and higher volatility, you can confidently leverage Webull’s 24-hour trading to gain a significant edge in the modern financial landscape.
