Why I Trade SPX 0DTE Options: Leverage, Time, and Tax Advantages
After years of trading both SPY and SPX options, I've made a deliberate choice: I trade SPX 0DTE options exclusively. Here's why this decision has transformed my trading results and why it might change yours too.
This isn't about preference—it's about measurable advantages. SPX 0DTE options offer three critical benefits that SPY simply cannot match: superior leverage, time efficiency, and significant tax savings. Let me break down exactly how these advantages work and why they matter for your trading.
Bottom line: If you're trading SPY 0DTE options, you're leaving money on the table. The tax savings alone can be worth thousands per year, and that's before we talk about leverage and time efficiency. Read on to see exactly how much you could be saving.
The Three Core Advantages
Every trading decision should be backed by math and measurable outcomes. SPX 0DTE options deliver on three fronts that directly impact your bottom line.
1. Leverage: Turning Small Risks Into Significant Gains
With SPX 0DTE options, I regularly find trades that offer 100% to 300% returns, and occasionally 1,000% to 2,000% gains. This isn't hyperbole—it's the math of leverage working in your favor.
Consider a $100,000 account. By risking just $1,000 (1% of capital) on a single SPX 0DTE trade, you can grow your account by 1% to 10% in a single day. With over 220 trading days per year, the compounding effect is substantial.
Real Trade Examples
These are actual trades from my trading log. Not cherry-picked winners—these represent the types of opportunities that appear regularly when you understand the math behind SPX 0DTE options.
What makes these trades possible: Understanding price levels, time decay, and momentum. When SPX approaches key levels, 0DTE contracts can move 5x, 10x, or even 20x in minutes. The key is knowing when to enter and when to exit—and that comes from experience and a systematic approach.
2. Time: Trade in Hours, Not Days
As you can see from the examples above, most of my SPX 0DTE trades complete in 30 minutes or less. 90% of my trades are finished within 2 hours. This time efficiency is crucial for several reasons.
First, it eliminates overnight risk. You don't wake up to gap moves that can wipe out your position. Second, it allows you to trade around a real job. You don't need to stare at screens all day—set alerts at key levels, check price action when it matters, and execute when your edge appears.
The market moves in predictable patterns during specific times. SPX 0DTE options let you capitalize on these moves without committing your entire day to watching charts. I typically spend 15 minutes in the morning planning, set alerts, and then check in when price action aligns with my levels.
3. Math: The Measurable Edge
This is where SPX 0DTE options truly shine. The math isn't about guessing—it's about understanding time decay, premium extraction, and momentum.
I can take trades that I know will expire worthless by end of day, but I can enter at $0.50 and sell for $2-$4 before expiration. This isn't luck—it's math. The balance of time, premium, and momentum allows me to extract value from contracts that others write off as worthless.
With experience and accurate price level identification, I can estimate 0DTE contract prices when those levels are met intraday. This mathematical edge compounds over time, turning what looks like gambling into calculated risk-taking.
Why SPX Instead of SPY?
SPY now has 0DTE contracts too, so why choose SPX? The answer comes down to two critical factors that can make or break your trading: settlement and broker risk management.
Cash Settlement
SPX is cash-settled. There's no risk of margin calls or getting exercised. When your trade closes, cash is deposited directly into your account. No shares to manage, no margin requirements to worry about.
Avoid Broker Issues
I've had brokers close out SPY 0DTE trades during the last hour to manage their own risk. I've also had them prevent opening trades during the final hour—the exact time when 10x gains are most likely. With SPX, you maintain full control until expiration.
Can Small Accounts Trade SPX?
Yes, but you need to be more selective and take profits quickly. If you're targeting far out-of-the-money contracts, don't sit in them more than 30 minutes to an hour if they're not already profitable.
The Numbers: SPY vs SPX for Small Accounts
Let's say you're bullish and want to long SPY 557c or SPX 5570c. You have $5,000 in capital and want to allocate 10% ($500) to the trade.
SPX 5570c costs $5, SPY 557c costs $0.50. With $500, you can buy 10 SPY contracts or 1 SPX contract. If both move $2 in your favor, you make $1,500 either way. But here's where it gets interesting.
The Exercise Risk
10 SPY contracts = 1,000 shares. If exercised at close, that's $557,000 you need to secure. Will your broker let a $5,000 account carry that risk? Probably not. At 2:30-3:30 PM, if SPY dips to 557.20, your broker might close your SPY call trade, costing you $100, while your SPX trade remains untouched.
The Small Account Advantage
Here's something powerful: Instead of 1 SPX 5570c at $5, take 50 SPX 5590c at $0.10. Same $500 risk. When SPX hits 5590 at 3:55 PM, these might be worth $2. You sell for $10,000 - $500 = $9,500 profit.
Yes, contracts at $0.10 are cheap for a reason—99.5% expire worthless. But for that 1 in 200 chance you're right, you can turn $500 into $10,000 using SPX options. Try that with SPY, and your broker will reject the order or immediately close it. They won't risk letting you control $2.7 million worth of shares into the close.
Small accounts can definitely trade SPX, but you need patience on 0DTE or go far out-of-the-money on next-day contracts.
Why SPX vs SPY
SPX options receive special tax treatment that can save you thousands in taxes compared to SPY options.
The 60/40 Split
SPX options are taxed using a 60/40 split: 60% of gains are treated as long-term capital gains (lower rate) and 40% as short-term capital gains (higher rate), regardless of how long you hold the position. SPY options are taxed as short-term capital gains if held less than one year.
Estimated Tax on SPY
Estimated Tax on SPX
Tax calculations are estimates based on the highest federal tax bracket (37% short-term, 20% long-term). Your actual tax rate may vary based on your income, state taxes, and other factors. Consult a tax professional for advice specific to your situation.
The Dangers: What You Must Know
Trading SPX 0DTE options is not for everyone. This is a high-risk, high-reward environment that requires discipline, patience, and proper risk management.
Capital and Risk Management is Essential: Once you're on the wrong side of time and direction, a contract can easily go to zero. I've lost entire positions multiple times.
Volatility Can Wipe You Out: A news event or choppy action can trigger a 50-80% loss within minutes. You must have strict stop-losses and position sizing rules.
Patience is Required: Trading SPX 0DTE takes planning. Patience for entries. Patience for exits. There are significant gains and losses that can be incurred. This is not a get-rich-quick scheme.
Why This Matters: The Professional Edge
I've been trading SPX 0DTE options for years, and the results speak for themselves. The combination of leverage, time efficiency, and tax advantages creates a compounding effect that SPY simply cannot match.
But here's what most traders miss: it's not just about the mechanics. It's about understanding the math, identifying accurate price levels, and having the discipline to execute when your edge appears. This is what separates professional traders from gamblers.
The methodology I use relies on identifying accurate price levels and precisely estimating 0DTE contract prices when those levels are met intraday. This isn't guesswork—it's a systematic approach that has yielded returns from -100% to +2,600% across different trades.
The Math Behind the Results
These numbers aren't marketing—they're the result of a systematic approach to SPX 0DTE trading. The methodology focuses on:
- Identifying accurate price levels using technical analysis and market structure
- Precisely estimating 0DTE contract prices when those levels are met intraday
- Risk management that limits losses while allowing winners to run
- Time efficiency that fits around a real job or other commitments
This isn't about getting lucky on a few trades. It's about having a repeatable process that works across different market conditions. The tax advantages of SPX mean you keep more of what you make, and the leverage means you can grow small accounts faster than with traditional strategies.
