0DTE Iron Condor on SPY: Complete Strategy Guide
The 0DTE iron condor is one of the most popular strategies for daily income traders. You're selling a call spread and a put spread simultaneously, betting that SPY stays within a range for the rest of the day.
How a 0DTE Iron Condor Works
You collect premium from both sides and profit if SPY stays between your short strikes.
Example trade at 10:00 AM with SPY at $545:
| Leg | Strike | Action | Premium |
Net credit: $0.42 ($42 per condor) Max loss: $0.58 ($58 per condor) Breakeven range: $540.58–$549.42
You need SPY to stay within an $8.84 range — roughly 1.6% — for the rest of the day. On a typical trading day, SPY's full range is about 0.7–1.2%, so you have a cushion.
Strike Selection Rules
The key to a profitable 0DTE iron condor is strike placement. Here's the framework:
Short strikes: Place at approximately the 10-delta level on each side. This gives you roughly an 80% probability of profit on each wing.
Width: Use $1-wide spreads on SPY. Wider spreads ($2 or $3) increase max loss disproportionately without adding much premium.
Practical method: Look at the Expected Move for the day. If SPY's 0DTE expected move is ±$3.50, place your short strikes at $4.50–$5.00 away from the current price. This gives you a buffer beyond the expected range.
Entry Timing
Enter between 9:50 AM and 10:30 AM ET. This gives you:
Avoid entering after 1:00 PM. With less time remaining, you collect less premium, and any late-day momentum move can blow through your strikes before theta saves you.
Managing the Trade
Scenario 1: SPY Stays in Range (Most Days)
The condor decays toward zero. Close at 50% of max profit ($0.21 in our example) or let it expire worthless. Closing at 50% is statistically better because it frees up capital and avoids last-hour gamma risk.
Scenario 2: SPY Tests One Side
If SPY moves to within $0.50 of a short strike before 2:00 PM, close the threatened side for a loss and let the profitable side expire. Don't try to adjust — by the time a 0DTE condor is in trouble, it's usually too late to roll.
Scenario 3: SPY Blows Through a Strike
Accept the max loss. With $1-wide spreads, your max loss per condor is manageable. This is why position sizing matters — a max loss should be an annoyance, not a catastrophe.
Position Sizing
| Account Size | Max Condors Per Day | Max Risk | |--------------|--------------------|-----------|
Keep total risk per day below 2% of your account. Some days you'll hit max loss, and you need to survive those drawdowns.
