How to Trade 0DTE Options

What Are 0DTE Options?

0DTE (zero days to expiration) options expire on the same day you trade them. These options have no time value left — they are purely driven by intrinsic value and the intraday price movement of the underlying. SPY, SPX, QQQ, and some individual stocks offer daily expirations that make 0DTE trading possible.

0DTE options have exploded in popularity because they offer high leverage, fast results, and the ability to trade directionally or sell premium multiple times per week.

Step 1: Understand the Risks

Before you trade 0DTE, know what you are getting into:

Gamma is extreme. Small moves in the underlying cause massive percentage swings in the option price.
There is no time to recover. If the trade goes against you, there is no "tomorrow" to hope for a recovery.
Losses can happen fast. A $100 credit spread can hit max loss in minutes during a volatile session.
It can be addictive. The fast action creates a gambling-like dopamine cycle. Be aware of this.

Step 2: Choose Your Underlying

SPX (S&P 500 Index): The most popular 0DTE underlying. Cash-settled, no assignment risk, favorable tax treatment. Daily expirations (Mon-Fri).

SPY: Share-settled. Slightly wider spreads than SPX but still very liquid. Mon/Wed/Fri expirations.

QQQ: Nasdaq-100 ETF. More volatile than SPY. Mon/Wed/Fri expirations.

Stick to SPX or SPY for 0DTE. The liquidity is unmatched.

Step 3: Pick Your Strategy

Selling iron condors (most popular 0DTE strategy):

Sell a put spread and a call spread well outside the expected intraday range
Collect a small credit ($0.50-$2.00 on SPX)
Risk is defined by the spread width
Win rate is high but losses can be large relative to premium

Buying directional options:

Buy calls or puts for a quick directional bet
Very cheap ($0.50-$3.00 for OTM options) but high probability of expiring worthless
Use for momentum trades or mean reversion setups

Selling credit spreads (one side):

Sell a put spread if bullish or a call spread if bearish
Similar to a half iron condor
Cleaner to manage than a full four-leg position

Step 4: Set Your Rules

0DTE demands strict rules. Write these down before trading:

Max risk per trade: No more than 1-2% of your account. One bad 0DTE trade should not hurt you.
Daily loss limit: If you lose $X in a day, stop. Walk away. Come back tomorrow.
Time-based exits: Close all positions by 3:00-3:30 PM ET. The final 30 minutes can be wild.
No averaging down. If a 0DTE trade goes against you, close it. Do not add more contracts.
No revenge trading. After a loss, take a break. Do not immediately enter another trade to make it back.

Step 5: Timing Your Entries

9:30-10:00 AM: Volatile open. Wait for the market to settle unless you have a specific setup.
10:00 AM-12:00 PM: Best window for selling premium. IV is settling and directional bias is forming.
12:00-2:00 PM: Lunch hour is typically quiet. Good for iron condors.
2:00-3:30 PM: Afternoon can bring reversals. Close positions before the final 30 minutes.
3:30-4:00 PM: Wild finish. Avoid unless you are experienced and specifically playing the close.

Step 6: Manage the Trade

For selling strategies:

Close at 50-75% of max profit. On a 0DTE iron condor that collected $1.50, close when you can buy it back for $0.40-$0.75.
If one side is threatened, close the whole position. Do not try to hold and hope.
Use stop losses at 2x the credit received.

For buying strategies:

Set a profit target (100-200% return on the option) and take it when it hits.
Cut losses quickly. If the option loses 50%, close and move on.

Step 7: Start Small and Track Everything

Trade one contract at a time for at least 2-4 weeks
Track every trade: entry time, exit time, strategy, P&L
Review weekly. Calculate your win rate, average win, average loss
Only scale up after proving consistency

Common Mistakes

Trading too large — one bad 0DTE trade can wipe out a week of gains
Not having a daily loss limit
Holding into the close hoping for a recovery
Getting addicted to the action and overtrading
Selling spreads too close to the money for a bigger premium

Summary

0DTE trading is fast, exciting, and risky. Stick to SPX or SPY. Sell iron condors or credit spreads outside the expected intraday range. Use strict rules: 1-2% max risk per trade, daily loss limits, time-based exits. Start with one contract and scale up only after proving consistent profitability.
