You’ve likely noticed that zero-day-to-expiration (0DTE) options have become a go-to tool for intraday trading in recent years. Data shows that in 2025, 0DTE options account for 61% of S&P 500 options trading volume. These products allow you to capture market fluctuations within a very short timeframe, enabling flexible market entries and exits. Intraday traders are drawn to 0DTE options for high-frequency trading. However, you must approach them rationally, fully understanding their risks and suitability.

Key Points

• Zero-day-to-expiration (0DTE) options are contracts that expire on the same day they are traded, ideal for intraday traders aiming to capture short-term market movements.
• The low-cost nature of 0DTE options allows traders to engage in high-leverage trades with less capital, flexibly seizing short-term opportunities.
• High volatility and time pressure are the primary risks of 0DTE options, requiring traders to set stop-losses and avoid emotional decisions.
• Trend-following buying and seller strategies are effective methods to improve win rates and stabilize returns.
• Beginners should prioritize learning relevant knowledge, emphasize risk management, choose suitable brokerage platforms, and gradually enhance trading skills.

Definition

To understand this intraday trading weapon, you first need to know what zero-day-to-expiration (0DTE) options are.

• 0DTE options are option contracts that expire at the end of the current trading day.
• All option contracts become 0DTE options on their expiration day.
• These are also called same-day expiration options, referring to contracts with less than one day until expiration.

In the U.S. stock market, 0DTE options are commonly seen in index and ETF options. You can buy or sell these contracts on their expiration day to capture short-term market movements.

Characteristics

You’ll find that 0DTE options differ significantly from standard options.

• 0DTE options have an extremely short lifespan, typically lasting only a few hours.
• You can leverage intraday price movements and volatility spikes for high leverage and low entry costs.
• Their time value decays rapidly within the day, which is particularly advantageous for sellers.
• You need to continuously monitor the market, as price changes happen quickly, leaving little time for decisions.
• Market events, such as corporate earnings announcements, can significantly impact option value on expiration day.
• Trading volume for 0DTE options has surged in recent years, especially in major U.S. index option markets, making them a preferred tool for many intraday traders.

Tip: While 0DTE options are hailed as an intraday trading weapon, you must manage risks carefully to avoid losses from rapid intraday fluctuations.

Advantages of the Intraday Trading Weapon

Low Cost

When using 0DTE options, you’ll notice their transaction costs are significantly lower than those of longer-term options.

• Market makers, facing irrational demand, can operate with lower transaction costs.
• They typically set prices with high risk-adjusted returns, making it cheaper for you to trade 0DTE options.
• You can participate in high-leverage intraday trading with minimal capital.
• This low-cost feature allows frequent market entries and exits, enabling you to seize short-term opportunities flexibly.

If you want to experience the efficiency of this intraday trading weapon, the low cost is a key advantage. For example, in the U.S. market, many traders choose 0DTE options for high-frequency trading, reducing fees and capital commitment.

Flexibility

Flexibility is critical in intraday trading, and 0DTE options offer exceptional operational freedom.

• You can leverage the rapid decay of option premiums within a single trading day to adjust strategies.
• These options provide lower upfront costs and higher leverage, allowing you to adapt to market changes easily.
• You can quickly adjust positions to respond to breaking news or market fluctuations.
• Common strategies include time decay techniques and structured spreads to handle various market conditions flexibly.
• You can use technical analysis to identify short-term trends, set clear targets and stop-losses, and reduce risks.
• Experienced traders often employ scalping and volatility trading to profit from short-term market movements.

In practice, you can adjust your trading direction in real-time based on market changes, a core advantage of this intraday trading weapon.

Time Value Decay

When trading 0DTE options, you’ll notice the rapid decay of time value.

• The time decay curve for 0DTE options is extremely steep, almost a compressed version of longer-term options.
• In the latter part of the trading day, especially after 3:30 PM, time value decay accelerates significantly.
• Compared to longer-term options, 0DTE options lose time value much faster, particularly as the trading day ends.
• As a seller, you can capture premiums through rapid time decay for quick returns.
• Time decay is measured by the theta metric; higher theta means faster extrinsic value loss.
• Many sellers are attracted to this rapid decay and high-return potential, actively participating in this intraday trading weapon.

If you can master the pattern of time decay, you can achieve profits in a very short time, especially if you prefer high-frequency trading.

Rapid Returns

With 0DTE options, you can achieve returns in an extremely short timeframe.

• These options have high volatility and leverage, where small price movements in the underlying security can lead to significant profits or losses.
• Many U.S. market traders set a 15% profit target after the 10:15 AM opening and complete trades quickly.
• Studies show that iron butterfly strategies with small profit targets and stop-losses perform well with high win rates.
• The table below illustrates the rapid return performance of different strategies:

• In a real-world case, traders used technical and fundamental analysis to identify a stock facing strong resistance, anticipating a price drop.
• They selected a 0DTE put option near the market price, set a stop-loss, and closely monitored price changes.
• When the price dropped and the option value rose, they exited promptly, repurchasing the shorted option to profit from the price difference.

If you leverage the rapid-return potential of this intraday trading weapon, you can capture multiple profit opportunities in a single day, but risk management is essential.

Major Risks

When using 0DTE options, you must recognize their high-risk nature. While often called an intraday trading weapon, you need to approach them rationally and not overlook their significant risks. Below, I’ll analyze the risks from three perspectives: high volatility, time pressure, and liquidity risk.

High Volatility

You’ll notice that 0DTE options are highly sensitive to small changes in market prices.

• The leverage effect of 0DTE options is pronounced, where slight fluctuations in the underlying asset’s price can cause significant option value changes.
• During market volatility, 0DTE option prices can fluctuate dramatically, far more than longer-term options.
• You may encounter sudden price spikes or drops, amplifying both profits and losses.
• This high volatility requires constant market monitoring and quick reactions to avoid significant losses.

Tip: When trading high-volatility products, always set stop-loss and take-profit levels to avoid emotional decisions.

Time Pressure

When trading 0DTE options, time pressure is intense.

• These options have only a few hours of validity, requiring decisions in a very short timeframe.
• If the underlying asset doesn’t move significantly during the day, you, as a buyer, may lose the entire premium.
• Sellers without hedging may face unlimited losses, especially if the buyer exercises the option.
• You need to monitor the market continuously and adjust strategies quickly to avoid missing optimal timing.
• Time pressure can lead to decisions under stress, increasing the likelihood of emotional trading and risks.
• Experienced traders handle time pressure better, but beginners often struggle to keep pace.

Note: When trading under high pressure, prepare a trading plan in advance to avoid impulsive decisions.

Liquidity Risk

When trading 0DTE options, you must also consider liquidity risk.

• During market turbulence, 0DTE option liquidity can drop sharply, widening bid-ask spreads.
• Increased high-frequency trading activity can destabilize option market quotes, affecting your execution efficiency.
• Studies suggest that the popularity of 0DTE options may amplify market volatility, potentially triggering crises like the 2018 Volmageddon event.
• In the U.S. market, short-term options performed poorly during the financial crisis and pandemic, with extreme profit and loss volatility, making consistent gains difficult.
• In low-liquidity periods, you may struggle to execute trades at desired prices, leading to additional losses.

Tip: During low-liquidity periods, choose contracts with high trading volume and monitor market depth closely.

When participating in 0DTE option trading, prioritize risk control. You can reduce risks by setting stop-losses, diversifying investments, and monitoring in real-time. Rational participation and scientific capital management are key to long-term profitability with this intraday trading weapon.

Must-Learn Strategies

Trend-Following Buying

In intraday trading, you can adopt a trend-following buying strategy. By observing market trends and selecting 0DTE options aligned with the dominant direction, you can improve your win rate. Data shows trend-following performance across different timeframes:

You can see that trend-following strategies perform better with longer timeframes, offering higher win rates and lower drawdowns.

Seller Strategies

If you prefer stable returns, consider seller strategies. Selling 0DTE options allows you to collect time value premiums, but note the following:

• Understand liquidity risk.
• Monitor gamma risk.
• Watch for execution risk.
• Pay attention to time decay.
• Closely track position changes.

In practice, sellers must be cautious of gamma fluctuations and liquidity issues. By controlling position sizes and setting timely stop-losses, you can improve success rates. Studies show that well-managed seller strategies can achieve a 60% win rate.

Volatility Arbitrage

You can also use volatility arbitrage strategies. 0DTE options have high volatility risk premiums, with sellers often demanding greater compensation. Research indicates that when 0DTE option open interest increases, intraday volatility in the underlying index decreases, suggesting a stabilizing effect. You can capture arbitrage opportunities using spread strategies during abnormal volatility periods.

Risk Management

When using this intraday trading weapon, risk management is critical. Professional traders typically:

You can reduce losses from extreme market conditions by diversifying investments, setting stop-losses, and closing positions promptly.

Case Studies

In practice, you can refer to these common case studies:

• Scalping: Capture small fluctuations multiple times, entering and exiting the market quickly.
• Directional Bets: Predict same-day price movements and select 0DTE options in the corresponding direction.
• Hedging: Use 0DTE options to counter short-term risks while holding longer-term positions.
• Real-World Example: A trader predicted a rise in the S&P 500 index due to economic news, bought a 0DTE call option, and sold it for a significant profit after the expected rise.

These strategies and cases help you better understand and apply 0DTE options, improving intraday trading efficiency.

Suitable Traders and Recommendations

Suitable Traders

When considering 0DTE option trading, evaluate your trading style and risk tolerance. 0DTE options are better suited for:

• Traders with high risk tolerance, capable of handling sharp market fluctuations.
• Those favoring short-term speculative strategies for quick profits.
• Traders skilled at capitalizing on short-term price movements in underlying assets.
• Those willing to try asymmetric strategies for higher potential returns.
• Experienced intraday traders able to make rapid decisions.

In the U.S. market, many professional traders use 0DTE options for intraday hedging or short-term arbitrage. If you seek efficiency and flexibility, these products may suit you.

Considerations

If you’re a beginner or have low risk tolerance, proceed with caution. 0DTE options have significant market volatility, making risk management crucial. Consider these recommendations:

• Prioritize learning relevant knowledge. Many U.S. brokers offer extensive educational resources, including articles, videos, and online courses to help you understand option trading mechanics.
• Emphasize risk management. Properly set stop-losses and position sizes to protect your capital effectively.
• Choose a suitable brokerage platform. Opt for brokers with strong customer service, reasonable fees, and robust research tools.

For novice traders, start with simulated trading to build experience and gradually improve risk control skills. Rich educational content and effective risk management strategies are key to protecting yourself in volatile markets. Selecting the right brokerage platform also supports your trading success.

In practice, assess your abilities rationally and avoid following trends blindly. Continuous learning and scientific capital management are essential for steady improvement in intraday trading.

By choosing 0DTE options for intraday trading, you can enjoy high flexibility and rapid returns. However, you must recognize the risks posed by high volatility and time pressure. Select strategies based on your risk tolerance and trading experience. Continuous learning and disciplined capital management will help you leverage this “intraday trading weapon” to enhance trading efficiency.
