Iron Condor: Definition, Setup & Payoff Explained
How an Iron Condor Works
An iron condor has four legs — two puts and two calls — all on the same stock and expiration:
| Leg | Action | Strike | Purpose |
|---|---|---|---|
| 1. Long put | Buy | Lowest (A) | Caps downside risk on the put side |
| 2. Short put | Sell | Lower-middle (B) | Collects premium — bull put spread |
| 3. Short call | Sell | Upper-middle (C) | Collects premium — bear call spread |
| 4. Long call | Buy | Highest (D) | Caps upside risk on the call side |
The short put and short call generate the credit. The long put and long call are your insurance — they define the maximum loss if the stock breaks out of the range. The distance between B and C is your profit zone; the distance between A and B (or C and D) is the width of each spread.
Iron Condor Example
Stock XYZ trades at $100. You set up the following iron condor expiring in 30 days:
| Leg | Strike | Premium |
|---|---|---|
| Buy $90 put | $90 | −$0.40 (paid) |
| Sell $95 put | $95 | +$1.20 (received) |
| Sell $105 call | $105 | +$1.30 (received) |
| Buy $110 call | $110 | −$0.50 (paid) |
If XYZ stays between $95 and $105: All four options expire worthless. You keep the entire $160 credit. This is the ideal outcome.
If XYZ drops to $88: The put spread is fully in-the-money. You lose $5.00 on the put spread minus the $1.60 credit = net loss of $340. The call spread expires worthless.
If XYZ rises to $112: The call spread is fully in-the-money. Same math — net loss of $340. The put spread expires worthless.

| Above $110 (long call strike) | Max loss: $340 |
When to Use an Iron Condor
Neutral outlook. You expect the stock to trade sideways or within a tight range over the next few weeks. The iron condor is built for low-movement environments.
High implied volatility. When implied volatility is elevated, option premiums are inflated — which means you collect a fatter credit. If IV then drops (a volatility crush), the options lose value faster, letting you close the trade early for a profit.
Income generation. Iron condors are a repeatable income strategy. Many traders sell them monthly on indices or liquid stocks, aiming to collect small, consistent credits over time.
The Greeks in an Iron Condor
Delta is near zero at entry. The bullish put spread and the bearish call spread offset each other. The position is direction-neutral — you don’t want the stock to move at all.
Theta is your profit engine. You’re net short options, so time decay works in your favor every day. The closer you get to expiration without a breakout, the more of the credit you keep.
Vega is negative. A drop in implied volatility helps you — all four options lose value, and since you’re net short, that’s a good thing. This is why iron condors perform well after IV spikes.
Gamma is your risk. Gamma is negative and grows as expiration approaches. If the stock starts moving toward one of your short strikes late in the trade, the position can swing from profit to loss quickly. This is the main reason traders close early.
Iron Condor vs. Strangle
| Feature | Iron Condor | Short Strangle |
|---|---|---|
| Legs | 4 (two spreads) | 2 (naked short call + naked short put) |
| Max loss | Defined (spread width − credit) | Theoretically unlimited |
| Credit collected | Smaller (long options cost money) | Larger (no insurance legs) |
| Margin requirement | Lower and defined | Much higher |
| Best for | Defined-risk income traders | Experienced sellers with large accounts |
Think of an iron condor as a short strangle with training wheels. You give up some credit in exchange for defined risk and lower margin. For most retail traders, the iron condor is the more practical choice.
Risk Management
Position sizing. Because max loss is defined, you know exactly how much is at risk per trade. A common guideline is to risk no more than 2–5% of your account on any single iron condor.
Early exit rules. Close at 50% of max profit or when the stock approaches a short strike. Don’t let a winning trade turn into a loser by clinging to the last dollar of credit.
Adjustment techniques. If the stock drifts toward one side, you can roll the tested spread further out or close the threatened side and keep the untested side running. These adjustments are part art, part math.
Key Takeaways
- An iron condor combines a bull put spread and a bear call spread for a net credit.
- Maximum profit equals the net credit received — achieved when the stock stays between the short strikes.
- Maximum loss is defined: spread width minus the credit, on either side.
- Time decay and declining implied volatility are the two forces that drive profits.
- Most traders close at 50% of max profit rather than holding to expiration.
- The reward-to-risk ratio is typically unfavorable — one loss can erase several wins, so risk management is critical.
FAQ
What is the maximum profit on an iron condor?
The maximum profit is the net credit received when you open the trade. You keep this full amount if the stock closes between the two short strikes at expiration and all four options expire worthless.
What happens if only one side of the iron condor is breached?
Only the breached spread loses money. The other spread expires worthless, and you keep that side’s credit. Your net loss is the loss on the breached spread minus the total credit received.
How do I choose the strikes for an iron condor?
Many traders select short strikes with a delta between 0.15 and 0.30 — roughly a 70–85% probability of expiring out-of-the-money. The long strikes are typically $5 or $10 further out, depending on how much risk you want to define. Wider spreads collect more credit but risk more per trade.
Is an iron condor a good strategy for beginners?
It’s one of the more accessible multi-leg strategies because risk is fully defined. However, managing four legs simultaneously, understanding adjustment techniques, and accepting the unfavorable reward-to-risk ratio requires experience. Start small, paper trade, and use strict exit rules.
How does an iron condor compare to a butterfly spread?
Both are range-bound strategies with defined risk. A butterfly targets a very specific price at expiration and costs a debit. An iron condor targets a wider range and collects a credit. The iron condor is more forgiving — it profits across a broader zone — but the butterfly has a higher maximum reward relative to capital at risk.
