Can You Trade Options 24 Hours A Day?

TL;DR: You cannot trade most options 24 hours a day. Standard U.S. equity options trade from 9:30 AM to 4:00 PM ET, with some index options offering extended hours. Pre-market and after-hours trading provide alternatives for traders seeking more flexibility outside regular market sessions.

Can you trade options around the clock like some stock traders now can? The short answer is no—at least not for most options contracts. While the stock market has expanded to offer 24-hour trading on select securities, the options market operates under different rules with more limited hours. However, there are alternatives that bring you closer to round-the-clock trading. This guide explains why 24 hour options trading is not available, outlines the standard trading hours you need to know, and explores viable alternatives including pre-market and after-hours sessions.

Can You Trade Options 24 Hours a Day?

The answer is generally no. While certain stocks may be available for 24-hour trading on specific markets, options contracts are subject to different regulations and typically cannot be traded around the clock. However, trading windows are expanding. Longbridge now offers pre-market US options trading, allowing investors to trade eligible contracts before the market opens. Aside from these extended sessions, standard equity options are traded during regular market hours, from 9:30 AM to 4:00 PM Eastern Time (ET), Monday through Friday.

Some index options on the Chicago Board Options Exchange (CBOE), such as S&P 500 Index (SPX), CBOE Volatility Index (VIX), and Mini-SPX Index (XSP) options, do offer nearly 24-hour trading five days a week. However, these are specialised products primarily used by institutional investors for hedging purposes, not typical retail options trading.

Why Is 24 Hour Options Trading Not Available?

Several structural and practical reasons prevent options from trading 24 hours a day:

Low Trading Volume Outside Market Hours

Options trading depends heavily on the underlying stock's price movements and volatility. When the stock market is closed or operating in thin overnight sessions, there simply is not enough trading activity to support a healthy options market.

Liquidity Challenges

Liquidity refers to how easily you can buy or sell an asset without significantly affecting its price. During regular market hours, options benefit from deep liquidity with many buyers and sellers. Outside these hours, liquidity drops significantly, leading to:

Wider bid-ask spreads (the difference between buying and selling prices)

Difficulty executing trades at fair prices

Potential for slippage, where your order fills at a worse price than expected

Pricing Accuracy Issues

Options prices are derived from complex models that rely on real-time data from the underlying stock. When the stock market operates with minimal activity, options pricing becomes less reliable and potentially inaccurate.

Options Trading Hours Explained

Understanding when you can trade options helps you plan your investment strategy effectively. Here is a breakdown of standard options trading hours:

According to NASDAQ's official trading calendar, most equity options trade during the standard 9:30 AM to 4:00 PM ET window. A select group of exchange-traded fund (ETF) options trade until 4:15 PM ET.

Expiration Day Considerations

On options expiration dates, typically Fridays, traders face tighter windows:

Opening new contracts: Until 3:00 PM ET

Closing existing positions: Until 3:30 PM ET for stocks and ETFs, or 4:00 PM ET for indices

These restrictions exist to manage settlement processes and reduce confusion as contracts reach their final trading day.

Alternatives to 24 Hour Options Trading

While 24 hour options trading is not standard for most equity options, investors can utilize pre-market sessions to manage positions outside of regular hours.

Pre-Market Trading Hours

Pre-market trading takes place before the official market opens at 9:30 AM ET. Longbridge provides access to pre-market options trading, allowing investors to trade eligible contracts before the regular session begins.

Benefits of Pre-Market Options Trading:

React to overnight news: Earnings announcements, economic reports, and global events often occur before U.S. markets open. Pre-market access lets you respond to developments before the regular session begins.

Time zone flexibility: For Singapore-based investors, pre-market hours fall during evening hours (SGT), making it more convenient to trade without staying up late.

Reduced competition: Fewer participants in pre-market sessions may result in different market dynamics compared to regular hours.

Longbridge Pre-Market Options Trading

Longbridge offers pre-market U.S. options trading from 5:00 PM to 10:30 PM SGT (4:00 AM to 9:30 AM ET). This extends your trading window by 5.5 hours before the regular market opens, covering symbols including QQQ, SPY, AAPL, AMD, AMZN, GOOGL, META, NVDA, MSFT, and TSLA.

After-Hours Trading Hours

After-hours trading sessions commence once the regular market closes at 4:00 PM ET. While stock trading typically continues until 8:00 PM ET, options trading hours are more restricted.

Benefits of After-Hours Trading:

Respond to earnings releases: Many companies announce quarterly results after the market closes. After-hours access lets you act on this information promptly.

Adjust positions: If news breaks that affects your holdings, you can make changes without waiting until the next trading day.

Global market correlation: Events in Asian and European markets can influence U.S. securities. After-hours trading helps you manage exposure to these movements.

Important Considerations for Extended Hours:

While after-hours trading offers convenience, be aware of these factors:

Lower liquidity compared to regular hours

Wider bid-ask spreads affecting trade costs

Potentially higher volatility due to fewer participants

Some order types may not be available

Tip: Limit orders can be used during extended hours sessions to maintain control over your execution prices. Market orders may fill at unexpected levels when liquidity is thin.

Frequently Asked Questions

Can I trade stock options overnight?

Generally, stock options cannot be traded overnight, even if the underlying stock itself is available for pre-market trading on some brokerage platforms. Standard equity options are only available during regular market hours (9:30 AM to 4:00 PM ET). Some index options on CBOE offer nearly 24-hour trading, but these are specialised instruments not suitable for all investors.

What is the difference between pre-market and after-hours options trading?

Pre-market trading occurs before the regular session opens (typically 4:00 AM to 9:30 AM ET), while after-hours trading happens after the market closes (4:00 PM to 8:00 PM ET). Both sessions feature lower liquidity and wider spreads than regular hours. Pre-market is useful for reacting to overnight news, while after-hours helps you respond to earnings announcements and closing-hour developments.

Are extended hours options trades riskier?

Extended hours trading carries additional considerations compared to regular sessions. Lower liquidity means wider bid-ask spreads and potentially less favourable execution prices. Volatility can also be higher with fewer participants. These sessions may be more appropriate for experienced traders who understand how to manage these factors.

The choice of which tool to utilize depends on your investment objectives, risk tolerance, market outlook, and experience level. Regardless of the method selected, it is essential to fully understand its mechanics, risk characteristics, and execution rules, while maintaining a robust risk management plan.
