Best 0DTE Trading Strategy: A Practical Guide for Intraday Options Traders

What actually qualifies as the "best" 0DTE trading strategy? If you've spent any time in options trading communities, you've likely seen the question asked dozens of ways. The short answer is: there is no single best strategy—but there is a best approach. And that approach starts with understanding what you're actually trading.

Zero-days-to-expiration (0DTE) options are contracts that expire on the same day they are traded. They now account for roughly half of daily S&P 500 index options volume, with Cboe research showing average daily volumes grew from nearly 390,000 contracts in Q1 2022 to nearly 2 million contracts in Q1 2025 . That growth tells you one thing clearly: traders are using these instruments—and many are figuring out how to do it effectively.

The Reality of 0DTE Trading

Before we get into strategy specifics, let's address what makes 0DTE different. These options compress an entire options lifecycle into hours. Theta decay is exponential, not linear. A $2.00 option at market open can be worth $0.30 by 2:00 PM if the underlying trades sideways . Meanwhile, gamma spikes near expiration, meaning a small move in the underlying can shift delta from 0.30 to 0.80 in minutes .

This isn't a "set it and forget it" instrument. As one practitioner put it, "0DTE is a scalping instrument, not a premium-selling setup. If you sell 0DTE, treat it as a day trade with hard stops" .

What the Best 0DTE Strategies Have in Common

The most effective 0DTE trading approaches share several core elements:

Defined risk is non-negotiable. Buying a single 0DTE call or put limits your loss to the premium paid. Selling naked options on 0DTE without defined risk is—to put it mildly—a high-risk endeavor. Spreads like bull put credit spreads or iron condors cap your maximum loss while allowing you to benefit from time decay .

Position sizing matters more than your entry signal. The most common mistake in 0DTE trading is oversizing positions. Because individual contracts are cheap, it's tempting to buy 20 or 50 contracts without feeling the risk. But 50 contracts at $0.30 each is $1,500 in premium, and if you're selling spreads, the risk is substantially higher. Many experienced traders limit 0DTE risk to no more than 1% of their account per trade .

You need a real-time monitoring system. Traditional end-of-day risk reports are useless for 0DTE portfolios. Positions expire before the reports are generated. Professional desks use intraday scenario analysis and continuous Greek monitoring. They run "what-if" simulations throughout the day to see how a 1-2% market move would impact their P&L .

Strategy Options for Different Styles

If you're directional and have a strong conviction, buying 0DTE calls or puts can work—but you need the move to happen quickly and significantly. Your premium decays every minute the market doesn't move in your favor .

If you prefer selling premium, credit spreads (bull put or bear call) allow you to benefit from theta decay while limiting your downside. A bull put credit spread, for example, involves selling a put at a chosen strike and buying a lower-strike put for protection. The credit received is your max profit, and the spread width minus the credit is your max loss .

For traders who expect volatility but aren't sure of direction, long straddles or strangles (buying both a call and a put) can pay off dramatically on explosive intraday moves. The challenge: if the market meanders, both options can lose value rapidly. Some traders "roll" the losing side—closing the decaying leg and buying a new position closer to the money to retain gamma exposure if the market reverses .

The Practical Challenge: Monitoring 0DTE Positions

Here's where many traders hit a wall. Managing 0DTE positions effectively requires constant attention. You need to track real-time price action, monitor your Greeks, watch for gamma flips, and be ready to act when your stop-loss or profit target is hit.

This is where having the right setup matters. If you're trading on MetaTrader 5 or MT4, you're already using a powerful platform—but 0DTE trading often requires you to juggle multiple windows, check positions constantly, and make quick decisions. Having to keep the full MT5/MT4 interface open and visible while you're trying to concentrate can add unnecessary friction.

Camovia Tray addresses this specific workflow problem. It turns your MT5 or MT4 into a system tray tool, allowing you to check live quotes by simply hovering over the tray icon—no need to bring up the full terminal window [citation:product]. When you need to manage open positions, the floating order window shows your unhedged positions with all key data: symbol, direction, lot size, open price, and current profit/loss [citation:product]. And when you need to close a position, it's two clicks—tap "Close" then confirm [citation:product].

This matters for 0DTE trading because speed and focus are everything. Being able to hide the MT5/MT4 main window from the taskbar and Alt+Tab view means fewer distractions when you're analyzing your next move [citation:product]. The ability to check your P&L without opening a full application window lets you stay locked into your trading screen while still monitoring your open positions.

Data Stays Local—A Critical Consideration

One concern that comes up frequently among retail traders is data privacy. When you're trading 0DTE, your position data and P&L are sensitive information. Camovia Tray reads all quote and position data directly from your local terminal—nothing gets uploaded to any external server [citation:product]. This is worth noting because some third-party trading tools require sending your data to external servers for processing.

Practical Takeaways for 0DTE Traders

Based on the research and real-world experience, here's what the best 0DTE trading approach looks like in practice:

1. Start with observation. Watch 0DTE price action for at least two weeks before trading real money . Understand how volatility behaves at different times of day.

1. Use defined-risk structures. Credit spreads, iron condors, or long options limit your maximum loss .

1. Size appropriately. Keep 0DTE position risk within 1-2% of your account value .

1. Set hard stops and respect them. 0DTE is unforgiving when you freeze and don't exit a losing position .

1. Monitor continuously. Use tools that streamline your workflow so you can focus on decision-making rather than interface management.

1. Avoid the final hour unless you're experienced. Liquidity dries up after 3:30 PM, and gamma risk skyrockets. Many traders close positions well before the closing bell .

The "best" 0DTE strategy depends on your risk tolerance, account size, and market view. But the common thread across all successful approaches is discipline: defined risk, proper position sizing, real-time monitoring, and a clear exit plan before you enter the trade.
