0DTE Strategy Guide: Iron Butterfly
The iron butterfly is a focused version of the iron condor that profits from minimal movement around a specific price. Learn how this high-premium strategy works in 0DTE.
The iron butterfly is a four-leg strategy similar to the iron condor, but with the sold options at the same strike (typically at-the-money). This creates a more aggressive structure that collects higher premium but requires the underlying to stay very close to the sold strike.
Basic Structure
- Legs: Sell 1 ATM call + Sell 1 ATM put + Buy 1 OTM call (wing) + Buy 1 OTM put (wing)
- Risk type: Defined risk — max loss is the wing width minus credit
- Directional bias: Neutral — profits most when the underlying pins at the sold strike
- Income: Higher net credit than an iron condor (ATM options have maximum time value)
How It Works
SPY is at $580. You sell the $580 call and $580 put, then buy the $582 call and $578 put as wings. Total credit: $1.60. Maximum loss: $2.00 - $1.60 = $0.40. If SPY closes exactly at $580, you keep the full $1.60. Breakeven points: $578.40 and $581.60.
Best Market Conditions
- Low-volatility, pinning days: When SPY is drifting around a key level
- Midday compression: Perfect timing when the market stalls after the morning session
- Options expiration pinning: Market makers hedging large open interest can keep the underlying near round numbers
Greeks Exposure
| Greek | Exposure | What It Means |
|---|---|---|
| Delta | Near zero (at entry) | Neutral at inception, shifts as the underlying moves |
| Gamma | Highly negative (-) | Very sensitive to movement — even small moves shift P&L rapidly |
| Theta | Highly positive (+) | Maximum time decay collection |
| Vega | Negative (-) | Benefits from IV contraction |
Why Traders Use It in 0DTE
The iron butterfly collects more premium than any other defined-risk strategy. On quiet 0DTE days where the underlying barely moves, the trader collects a large credit that decays rapidly throughout the session. The risk-reward can be very favorable when positioning is precise.
Primary Risk Factors
- Movement sensitivity: Even $1–$2 moves significantly impact P&L because the sold strikes are ATM
- Narrow profit zone: The underlying needs to stay within a tight range (breakevens)
- High gamma exposure: The most gamma-sensitive of all defined-risk strategies
- Closing difficulty: Four legs can be hard to close efficiently — always use single-order pricing
Exit Management for 0DTE
- Close at 25–50% of max profit — the narrow profit zone makes holding to expiration riskier than an iron condor
- If the underlying moves beyond your breakeven, close immediately
- This strategy requires the most active management of any defined-risk position
Safety Rating
Defined risk — moderate to high complexity. While risk is capped, the high gamma sensitivity and narrow profit zone make this more suitable for experienced 0DTE traders.
