Let’s be direct: 0DTE trading is exciting because it’s fast, but that speed is also what makes it incredibly risky. The internet is full of hype, but the reality is that most people who jump in without a plan end up losing money. The key to staying in the game is treating it like a business, not a lottery ticket. That means having a solid plan, strict risk management rules, and the discipline to follow them, especially when the market gets chaotic. This guide cuts through the noise to give you that framework. We’ll cover everything from position sizing and trade management to the specific, profitable 0DTE SPX strategies you can use to trade with a professional mindset.

Key Takeaways

  • Know the Playing Field: 0DTE trading is a game of speed where time decay is extreme. Your goal is to capture small, intraday profits, as these options expire at the end of the day, leaving no room to hold positions overnight.
  • Make Risk Management Your Top Priority: Your long-term success hinges on protecting your capital, not on winning every single trade. Stick to strict rules for position sizing and daily loss limits to ensure one bad trade doesn’t take you out of the game.
  • Trade with a Plan, Not on Impulse: Decide your entry, profit target, and maximum loss before you place a trade. Using tools like limit orders and setting clear exit rules (like the 50-65% profit rule) helps you execute with discipline and avoid emotional decisions.

What Are 0DTE SPX Options?

If you’ve spent any time in the options trading world, you’ve probably heard the buzz around 0DTEs. The term stands for “zero days to expiry,” and it’s exactly what it sounds like: trading options contracts that expire at the end of the very same day you open them. Think of it as the ultimate form of day trading, where you aim to profit from the market’s small, intraday movements without the risk of holding a position overnight.

These options are especially popular for trading the S&P 500 index, or SPX. Because the SPX is a broad measure of the entire market, it has incredible liquidity and predictable patterns that traders can use to their advantage. With 0DTE SPX options, you can place a bet on where you think the market will go in the next few hours. If you’re right, you can see significant returns. If you’re wrong, your option expires worthless at the end of the day. It’s a fast-paced approach that requires a clear strategy, but it offers a unique way to engage with the market’s daily rhythm. Cboe offers excellent 0DTE trading resources if you want to get more familiar with the official specifications.

0DTE vs. Traditional Options: What’s the Difference?

The biggest difference between 0DTE options and traditional weekly or monthly options comes down to one thing: time value. An option’s price is made up of intrinsic value (its actual worth if exercised now) and extrinsic value (which includes time value). Time value is like a premium you pay for the possibility that the option could become more profitable before it expires.

With traditional options, you have days, weeks, or even months for your trade to play out, so they have more time value baked into their price. 0DTE options, on the other hand, have virtually no time value left. They are an ice cube melting in the sun. This makes them much cheaper to trade, but it also means time is aggressively working against you. There’s no waiting around for the market to turn in your favor; your prediction has to be right, and it has to be right today.

Why Trade SPX for 0DTE?

So, why has trading 0DTE options on the SPX become so popular? The numbers speak for themselves. Trading volume has exploded, and now nearly 60% of all S&P 500 options volume comes from these same-day expiring contracts. This isn’t just a niche strategy anymore; it’s a major force in the market.

There are a few key reasons for this. First, the SPX is incredibly liquid, meaning there are always buyers and sellers ready to trade. This ensures you can enter and exit your positions smoothly at fair prices. Second, SPX options are European style and cash-settled. This is a huge advantage because it means you never have to worry about the assignment of actual shares. At expiration, the contracts are settled in cash, which simplifies the entire process. The combination of high volume and simple settlement makes the SPX the ideal underlying for this fast-paced 0DTE options strategy.

Key Greeks to Watch: Theta, Gamma, and Implied Volatility

When you’re trading on such a short timeline, the “Greeks” (the variables that measure an option’s risk) behave a bit differently. You don’t need to be a math whiz, but you do need to keep an eye on three key metrics.

First is Theta, which measures time decay. For 0DTE options, Theta is at its absolute peak. It’s constantly eating away at your option’s value with every minute that passes. If you’re buying options, Theta is your enemy. If you’re selling them, it’s your best friend.

Next is Gamma. Think of Gamma as the accelerator pedal for your option’s price. It measures how much your option’s Delta (its price sensitivity) will change when the SPX moves. On expiration day, Gamma is extremely high, meaning even a small move in the SPX can cause a huge swing in your option’s value. This is where the big profits (and big losses) come from.

Finally, watch Implied Volatility (IV). This reflects the market’s expectation of how much the SPX will move. A sudden drop in IV can crush the value of your option, even if the market moves in your direction.

Popular 0DTE SPX Strategies to Explore

Once you’re comfortable with the basics of 0DTE options, you can start trying out different strategies. Each one comes with its own risk profile and works best in specific market conditions, so the goal is to find an approach that feels right for you. Think of it like building a toolkit; the more strategies you understand, the better equipped you’ll be to handle whatever the market throws at you. Let’s walk through some of the most popular strategies traders use for 0DTE SPX options so you can see how they work.

Selling Credit Spreads

If you have a strong feeling about the market’s direction for the day, selling a credit spread is a great strategy to consider. It’s a straightforward directional bet with a built-in safety net. For instance, if you think the SPX will stay above a certain level, you can sell a put credit spread. This involves selling one option and buying another at a different price, which effectively caps your maximum risk. Cboe’s 0DTE trading resources explain this structure well. I love this approach because you know your exact risk upfront, which helps keep emotions in check while you capitalize on market movements.

Iron Condors

What if you expect a quiet, range-bound day? That’s the perfect scenario for an iron condor. This strategy is ideal when you don’t have a strong directional opinion and just think the market will stay between two price levels. You’re essentially selling both a call spread and a put spread at the same time, collecting a premium for betting on low volatility. Time decay is your best friend here, as the options lose value throughout the day. Just remember that you need to be prepared to actively manage the trade if the market makes a sudden, strong move and threatens to break out of your expected range.

Straddles and Strangles

For another way to profit from a stable market, you can look into selling straddles and strangles. When you sell a straddle, you sell both a call and a put option at the same at-the-money strike price. The goal is for the SPX to barely move, allowing you to collect the premium as time decay works its magic. A strangle is a bit more forgiving; you sell an out-of-the-money call and an out-of-the-money put, which gives the price more room to move. As TradingBlock points out, selling strangles is often considered a high-probability, lower-reward trade, making it a solid choice if you’re aiming for consistent, smaller profits.

Opening Range Breakout (ORB) Directional Trades

If you’re an early bird who likes to trade right at the market open, the Opening Range Breakout (ORB) strategy might be for you. This approach is all about capturing the momentum that often occurs shortly after the opening bell. You identify the high and low of the first few minutes of trading and then place a directional trade when the price breaks out of that range. Many traders use credit spreads to execute this on the SPX. This deep dive into the 0DTE strategy shows how it can be a powerful way to get in on early moves, making it a favorite among active day traders.

Bull Call Spreads and Bear Put Spreads

While many 0DTE traders focus on selling premium, buying options can be just as effective. Buying a vertical spread is an excellent way to make a directional bet with limited risk. If you’re bullish and think prices are heading up, you can buy a Bull Call Spread. If you’re bearish and expect a drop, a Bear Put Spread is your go-to. The strategy involves buying one option and selling another that’s further from the current price. It’s a defined-risk way to bet on market direction and one of the fundamental 0DTE options strategies that I think every trader should have in their playbook.

Automated and Algorithmic Approaches

Let’s be real: staring at charts all day is exhausting, and it’s easy for emotions to cloud your judgment. This is where automation can be a game-changer. Using an automated trading bot helps you execute your strategy with consistency and discipline, removing the temptation to make impulsive decisions. You can program a bot to enter and exit trades based on your specific rules, whether they’re tied to technical indicators or price levels. An automated trading bot can significantly improve your efficiency, which is a huge advantage in the fast-paced world of 0DTE trading.

How to Choose the Right 0DTE Strategy

Picking the right 0DTE strategy is less about finding a single “best” one and more about matching your approach to your personal trading style and the current market environment. What works on a quiet, range-bound day might not be the best choice during a volatile session driven by news. The key is to have a few strategies in your toolkit and know when to use each one. Let’s break down how to think through this choice.

High-Probability vs. High-Reward Setups

First, decide what you’re aiming for: consistent income or a big win? Strategies like selling credit spreads are designed for high probability. Here, you’re betting that the stock price will stay within a certain range, letting time decay work in your favor to erode the option’s value. These trades often have a higher chance of success but offer a limited, defined profit. On the other hand, buying a call or put is a high-reward play. You’re making a directional bet that can pay off significantly if you’re right, but the probability of success is lower, and time decay is working against you.

Match Your Strategy to Market Volatility

Volatility is a huge piece of the 0DTE puzzle. When implied volatility is high, option premiums are richer. This is a great environment for sellers, as you can collect more income for taking on the risk. Strategies like iron condors and credit spreads become more attractive because the potential reward is higher. However, high volatility also means the market can make sharp, unexpected moves. You must be prepared to monitor and manage the trade closely throughout the day. In low-volatility environments, premiums are lower, which can make selling less appealing, but it might create clearer opportunities for directional trades if a trend emerges.

Adapt Your Approach to Market Conditions

A successful 0DTE trader is never rigid. The market can pivot in an instant, so your strategy needs to be just as flexible. What looked like a quiet, range-bound morning can turn into a strong trend after a news announcement. This is why you have to watch your trades actively and be ready to act fast. If the market is choppy and unpredictable, it might be wise to trade smaller position sizes to manage risk effectively. Don’t force a strategy that doesn’t fit the day’s price action. If your plan was to sell a spread but the market is trending hard, it might be better to sit on the sidelines or switch to a directional approach.

What Are the Key Risks of 0DTE Trading?

While the fast-paced nature of 0DTE trading is a huge part of its appeal, it also comes with a unique set of risks. Understanding these challenges isn’t about scaring you away; it’s about preparing you to trade smarter. With contracts that expire in mere hours, there’s very little room for error. Small market ripples can turn into tidal waves, and time is never on your side. Let’s walk through the main risks you need to keep on your radar so you can protect your capital and make more informed decisions.

Gamma Risk: Why Small Moves Have Big Consequences

Think of gamma as the accelerator pedal for your option’s price. With 0DTE options, that pedal is pushed to the floor. Gamma risk is the danger that an option’s price will change dramatically with even a tiny move in the underlying stock. Because these options are so close to expiration, their sensitivity is off the charts. A small, unexpected shift in the SPX can cause your position’s value to swing wildly in seconds. This means a trade that looks like a winner can flip to a major loss before you even have time to react. Managing gamma exposure is critical to surviving in the 0DTE environment.

Liquidity and Execution Risk

In the world of 0DTE, getting in and out of a trade at a good price is everything. Liquidity risk means there might not be enough buyers or sellers for you to exit your position smoothly. You could get stuck in a trade or have to accept a much worse price than you wanted, a problem known as slippage. On top of that, there’s execution risk. You often have just a few seconds to lock in a profit or cut a loss. A poorly placed order or a moment of hesitation can be the difference between a successful trade and a losing one, making precise and swift trade execution a non-negotiable skill.

Time Decay Risk for Buyers

If you’re buying 0DTE calls or puts, time decay, or theta, is your biggest enemy. Think of your option’s value as a melting ice cube on a hot day; with 0DTE, it’s melting at an astonishing rate. Since the option expires at the end of the day, its time value evaporates with every passing minute. This rapid theta decay means the underlying index has to make a significant move in your favor, and quickly, just for you to break even. If the market stays flat or moves against you, the value of your option will quickly drain away, leaving you with a total loss by the end of the day.

How Market News Can Impact Your Trades

Scheduled economic reports, Federal Reserve announcements, or unexpected global headlines can send shockwaves through the market, and 0DTE options feel the impact instantly. A single piece of news can cause the SPX to gap up or down, creating extreme volatility that blows right past your profit targets or stop levels. Big institutional traders may also need to adjust their massive positions in response to news, adding to the chaotic price action. Always be aware of what’s on the economic calendar for the day, as a surprise announcement can turn a carefully planned trade into a gamble in the blink of an eye.

How to Manage Risk in 0DTE Trading

Let’s be direct: 0DTE trading is exciting because it’s fast, but that speed is also what makes it risky. The potential for a trade to go from profitable to a total loss can happen in minutes, not days. This isn’t the place for a “set it and forget it” mindset. Success in this environment depends almost entirely on having a rock-solid risk management plan before you even think about placing a trade.

A good plan isn’t just about protecting your capital from a catastrophic loss, although that’s a huge part of it. It’s also about protecting your mindset. Taking a big, unplanned hit can lead to emotional decisions like revenge trading, which almost never ends well. By defining your rules ahead of time, you create a structure that keeps you disciplined when the market gets chaotic. The goal is to stay in the game long enough to let your strategy work. These next steps will give you a framework for doing just that.

Control Your Position Size and Leverage

Your first line of defense in any trading strategy is controlling your position size. In the high-stakes world of 0DTEs, it’s absolutely critical. A common guideline is to never risk more than 3% of your total trading capital on a single trade. This means that if you have a $10,000 account, your maximum potential loss on one position should be no more than $300. This simple rule helps ensure that one bad trade won’t wipe out a significant portion of your account, allowing you to trade another day. Remember, leverage magnifies both gains and losses, so maintaining a conservative position size is key to long-term survival.

Use Limit Orders, Not Stop Orders

When you’re trading options that expire in a few hours, every penny counts. The market moves incredibly fast, and price fills can be unpredictable. This is why you should always use limit orders to enter and exit your trades. A limit order lets you set the maximum price you’re willing to pay or the minimum price you’re willing to accept. Using a market order can result in “slippage,” where you get a much worse price than you expected. Stop orders can also be tricky, as rapid price swings can trigger them prematurely. Using limit orders gives you precise control over your execution, which is essential when profits and losses are measured in seconds.

Know When to Roll or Manage a Losing Trade

Sometimes, despite your best analysis, a trade will start to move against you. Instead of just closing it for a loss, you might have the option to “roll” the position. This typically involves closing your existing trade and opening a new one with a later expiration date or a different strike price, often for a credit. For example, you might manage a challenged credit spread by adding another spread further out of the money. This can give your trade more time or room to become profitable. However, this is an advanced technique. You must approach it with very careful sizing to avoid compounding your risk on a losing position.

Set Daily Limits to Avoid Overtrading

Discipline is your best friend in 0DTE trading. One of the easiest ways to enforce it is by setting a hard daily loss limit. This is a predetermined amount of money that, once lost, signals you to stop trading for the day. No exceptions. A good rule of thumb is to ensure the total amount of money at risk across all your open trades never exceeds 5% of your total capital. This prevents you from falling into the trap of overtrading or revenge trading after a few losses. The 3-5-7 rule provides a solid framework for these limits. Hitting your daily limit isn’t a failure; it’s part of a professional process designed to protect your capital for future opportunities.

How to Time Your Entries and Exits

A great strategy is only half the battle. The other half is execution, and in the fast-paced world of 0DTE options, your timing for entering and exiting trades is critical. A few seconds can be the difference between a tidy profit and an unexpected loss. This is where having a clear, pre-defined plan becomes your most valuable asset. It’s not about predicting the market with perfect accuracy; it’s about setting rules that guide your decisions and keep emotions out of the driver’s seat. When you’re dealing with options that expire in hours, there’s no time for second-guessing. Your entry and exit points should be determined by your strategy, not by a gut feeling in the heat of the moment.

Successfully timing your trades involves a few key practices. First, you need to set achievable profit goals so you know when to take your money and walk away. You also need a firm plan for when to close your position, whether it’s a winner or a loser. Many traders also use patterns in price action to find better entry and exit signals. Finally, you can use technology to help you execute your plan with speed and consistency. Mastering these elements will help you trade with more confidence and control. Let’s get into how you can apply these techniques to your own trading.

Set Realistic Profit Targets (The 50-65% Rule)

It’s tempting to hold onto a winning trade, hoping to squeeze out every last penny of profit. But with 0DTE options, that approach can quickly turn a winner into a loser. A smart discipline many traders adopt is the 50-65% rule. This means you aim to close your trade once you’ve captured 50% to 65% of the maximum potential profit. For example, if you sold a credit spread for a $1.00 credit, you would look to buy it back for around $0.35 to $0.50.

Taking profits early helps you secure your gains and avoid the immense gamma risk that comes with holding a position into the final hour of trading. It’s a strategy that prioritizes consistency over chasing homeruns, helping you build your account steadily.

Decide When to Close: Early or at Expiration?

Before you even enter a trade, you should know exactly when you’re going to get out. This applies to both winning and losing scenarios. For winning trades, as we just discussed, closing early is often the wisest path. Letting a 0DTE trade run all the way to expiration is a high-risk gamble that experienced traders rarely take. The market can move against you in a heartbeat, erasing all your hard-earned gains.

For a trade that moves against you, your plan is even more important. While some advanced traders might manage a losing position by rolling it or adding another spread, this requires a deep understanding of the risks involved. For most traders, the best course of action is to define your maximum acceptable loss beforehand and stick to it. Cutting a small loss quickly is always better than letting it become a big one.

Use Technical Analysis for Entry and Exit Points

You don’t need to be a charting wizard to use technical analysis for 0DTE trading. It’s simply about using price action to find clues for when to enter and exit. One popular technique is watching the Opening Range Breakout (ORB). This involves observing the high and low of the SPX price in the first few minutes or hour of the trading day. A decisive move above the opening range high could signal a good entry for a bullish trade, while a break below the low could signal a bearish entry.

Using simple support and resistance levels or key moving averages can also provide a clear framework for your decisions. These technical indicators can help you identify logical points to take profits or cut losses, removing some of the guesswork and emotion from your trading.

Know When to Use Automated Trading Bots

In 0DTE trading, speed and discipline are everything. Emotions like fear and greed can cause you to hesitate or break your rules, leading to costly mistakes. This is where automated trading can be a powerful ally. Using a trading bot allows you to execute your strategy based on the exact rules you’ve set, without any emotional interference. You can program your bot to enter a trade when specific criteria are met and, just as importantly, to exit at your pre-defined profit target or stop-loss level.

This level of automation in trading ensures you stick to your plan with perfect consistency. It’s not a magic solution for profits, but it is an incredible tool for enforcing discipline, which is often the hardest part of trading.

Common 0DTE Trading Mistakes to Avoid

The speed of 0DTE trading can be thrilling, but it also magnifies the impact of common trading errors. Getting a handle on these potential pitfalls is just as important as learning the strategies themselves. Even seasoned traders can get tripped up if they’re not careful, especially when the market is moving fast and decisions have to be made in seconds. The good news is that most of these mistakes are entirely avoidable with a bit of awareness and discipline. By understanding where traders often go wrong, you can build better habits from the start, protect your capital, and give yourself a real shot at consistency. Let’s walk through some of the most frequent missteps I see traders make and, more importantly, how you can steer clear of them.

Over-Leveraging Your Positions

It’s easy to get carried away when you see the potential for quick profits, but over-leveraging is one of the fastest ways to blow up an account. With 0DTE options, small market moves can cause huge swings in your P&L. While you might score frequent small wins, one significant loss from an oversized position can wipe out all of your progress and then some. A core part of a sustainable approach is disciplined risk management. Never risk more than a small, predefined percentage of your account on a single trade. This ensures you can withstand the inevitable losses and stay in the game long enough to find consistent success. It’s not about winning every trade; it’s about making sure no single trade can take you out.

Trading Without a Plan

Jumping into a trade based on a gut feeling or market noise is a recipe for disaster. Without a clear plan, you’re just gambling. A poorly placed order can instantly turn a potentially winning trade into a losing one. Before you even think about clicking the buy or sell button, you need a well-defined trading plan that outlines your exact entry criteria, profit targets, and stop-loss levels. This plan is your rulebook, designed to keep emotions in check and guide your decisions when the pressure is on. When you have a plan, you know what you’re looking for, when to get in, and, most importantly, when to get out, whether you’ve hit your target or need to cut a loss.

Ignoring Liquidity and Execution

Not all options are created equal, especially when it comes to liquidity. Liquidity simply refers to how easily you can buy or sell an option at a fair price. For some less popular strikes, it can be difficult to get your order filled quickly because there aren’t many people trading them. This can lead to “slippage,” where the price you actually pay is worse than the price you saw on screen. Always check the bid-ask spread before entering a trade. A wide spread is a red flag for low liquidity. Sticking to highly traded instruments like the SPX helps, but even then, you should focus on strikes with high open interest and volume to ensure you can enter and exit positions efficiently.

Underestimating Time Decay

Time decay, or theta, is the engine of 0DTE trading, but it’s a powerful force that can work for or against you. For 0DTE options, this value loss happens at an incredibly rapid pace. If you’re buying options, theta is a constant headwind you’re fighting against; the option’s value is melting away with every passing minute. If you’re selling options, theta is what generates your profit, but it also means your window to be correct is extremely small. Underestimating how quickly this decay accelerates throughout the day is a critical error. You must be acutely aware of how much time is left and how it will impact your position’s value, whether you are a buyer or a seller.

Failing to Adapt to the Market

A “set it and forget it” approach doesn’t work in the fast-paced world of 0DTE trading. The market is a living, breathing thing, and its character can change completely from morning to afternoon. A strategy that was perfect for a quiet opening might be disastrous during a volatile, news-driven midday session. You need to watch your trades closely and be ready to act fast. This means staying informed about potential market-moving events and being flexible enough to adjust your strategy or close a position if conditions change. Being an adaptable trader means you can respond to what the market is giving you right now, not what you hoped it would do when you placed the trade.

Essential Tools for 0DTE SPX Trading

Trading 0DTE options without the right tools is like trying to navigate a racetrack blindfolded. The speed is intense, and you need immediate access to the right information to make smart decisions. Having a solid toolkit doesn’t just make trading easier; it’s fundamental to managing risk and executing your strategy effectively. These tools help you see the market clearly, act quickly, and stay disciplined when the pressure is on. Here are the three essentials every 0DTE trader should have.

Monitor the Greeks in Real Time

In 0DTE trading, the Greeks are your vital signs. They change at lightning speed, and you need to watch them just as closely. Because 0DTE options are very risky, monitoring the Greeks in real time is your best defense. Gamma, in particular, can explode as expiration nears, causing an option’s price to swing wildly with even small moves in the SPX. Your trading platform must provide streaming, real-time Greek values. This data allows you to gauge your position’s risk and potential movement instantly, helping you decide whether to hold, adjust, or close your trade before a small loss turns into a big one.

Scan for Optimal Strikes and Liquidity

Not all strikes are created equal, especially on expiration day. Liquidity, or the volume of buyers and sellers for a specific option, is everything. Low liquidity leads to wide bid-ask spreads, making it difficult to get in and out of trades at a good price. Some 0DTE options are newly listed that morning and can be harder to trade because fewer people are active. You want to focus on strikes with high open interest and volume, as these are easier to buy and sell. A good options scanner or a platform that clearly displays volume data is essential for quickly identifying the most liquid options and avoiding the costly trap of getting stuck in an illiquid position.

Use Automation for Consistent Execution

The 0DTE market moves too fast for hesitation. By the time you manually calculate and place an order, your opportunity might be gone. This is where automation becomes a game-changer. For consistent trading, using an automated trading bot or setting up automated orders can be incredibly helpful. Automation removes emotion from the equation and ensures your trades are executed with precision and discipline, exactly as your strategy dictates. Whether it’s a simple bracket order to take profit and cut losses or a more complex algorithm, automating your execution helps you stick to your plan when prices are flying and emotions are running high.

Frequently Asked Questions

Is 0DTE trading suitable for beginners? Honestly, I would not recommend jumping into 0DTEs if you are brand new to options. The speed and risk involved require a solid foundation. It’s better to first get comfortable with traditional weekly or monthly options, where you have more time for your trade to work out. Once you have a firm grasp of the Greeks, risk management, and a proven trading plan, you can consider exploring 0DTEs with a small portion of your capital.

Why is SPX the focus for 0DTEs instead of individual stocks? SPX is the go-to for a few key reasons. First, its liquidity is massive, which means there are always plenty of buyers and sellers, so you can enter and exit trades smoothly at fair prices. Second, SPX options are European style and cash-settled. This is a huge advantage because it means you never have to worry about being assigned actual shares of stock. At expiration, the contracts are simply settled in cash, which makes the entire process much cleaner and less complicated.

What’s the main difference between buying and selling 0DTE options? It really comes down to what you expect the market to do and how you want to use time decay. When you buy a 0DTE option, you need a significant price move in your favor, and you need it to happen quickly. Time decay is your enemy, as it’s rapidly eroding your option’s value. When you sell an option or a spread, you are betting that the price will stay within a certain range. In this case, time decay is your best friend, as you profit from the option’s value decreasing throughout the day.

How much capital should I have to start trading 0DTEs? There is no magic number, and it’s more important to think in terms of risk rather than a starting dollar amount. A critical rule is to never risk more than a small percentage of your trading account, like 1% to 3%, on any single trade. This ensures that one bad trade won’t have a devastating impact on your capital. Start small, prove you can be consistently profitable, and only then should you consider increasing your position size.

Do I really need an automated bot to trade 0DTEs? You don’t absolutely need one, but it can be an incredibly powerful tool for this specific style of trading. The main benefit of a bot is that it executes your strategy with perfect discipline, removing emotions like fear and greed from the equation. It can enter and exit trades at your exact price points without hesitation. You can certainly trade manually, but you must be extremely disciplined and focused, as the market moves too fast for second-guessing.
