What it is
An iron-condor is two credit spreads at once: a put spread below the market and a call spread above it, both out of the money, same expiration. It profits if the underlying stays between the short strikes until you close, and it loses (up to the width minus the credit) if it breaks out through either side. The "high IV" qualifier is the important part: the condor is a bet that implied volatility is overstating the coming move, and that bet only makes sense when implied volatility is actually high relative to its history.
The logic
Implied volatility spikes when the market is scared or a known event is approaching, and it typically overshoots the volatility that follows. Selling a condor in that state sells expensive insurance on both sides. As the event passes or fear fades, IV falls (vega gain), time passes (theta gain), and the condor can be closed for a fraction of its credit long before expiration.
The other side is the buyer of the strangle you have effectively sold: traders hedging or speculating on a large move. When the move arrives, they are right and you take a loss capped by the wings. The condor's edge is the average overpricing of those wings, which is small and lumpy.
Setup rules
- Market: index ETFs and cash-settled index options with liquid strikes at least 10 percent out of the money; large-cap stocks only outside earnings.
- Timeframe: 30 to 50 days to expiration.
- IV condition: iv-rank above 50, or implied volatility above the 30-day realised volatility by a wide margin. Below that, the credit does not pay for the tails.
- Strike selection: short strikes at about 0.10 to 0.16 delta on each side (roughly one standard deviation); wings 5 to 10 points wide on index ETFs; total credit at least one quarter of the wing width.
- Symmetry: in a falling market with high IV, the put side is closer in delta terms because of skew; consider shifting the call side closer or skipping it (that leaves a put spread, see credit-spread-program).
- Event rule: the expiration should not sit inside a scheduled macro event window unless the condor was opened specifically to sell the event's IV and sized for a full loss.
Entry, stop, target
Sell to open both spreads for one combined credit. Profit target: close the whole condor at 50 percent of the credit, or close each side independently at 75 percent of its own credit if the market has drifted. Loss rule: close the tested side when its short strike is touched or when the condor's value reaches 2x the credit. Time rule: close by 21 days to expiration regardless.
| Item | Value | Notes |
|---|---|---|
| Index ETF price | 400.00, IV rank 62 | |
| Put spread | Sell 370, buy 365 | Delta 0.14 |
| Call spread | Sell 430, buy 435 | Delta 0.12 |
| Total credit | 2.20 per share ($220) | Wings 5.00 each |
| Maximum loss | 2.80 per share ($280) | One wing width minus credit |
| Profit target | Close at 1.10 ($110 gain) | 50 percent |
| Loss close | Close at 4.40 (loss of $220) | 2x credit |
| Approximate R:R | Risk $220 to make $110, 0.5R | Requires roughly 70 percent win rate |
Only one side can lose at expiration, but both sides can lose before it if the market swings hard and fast in each direction, because you may have closed the tested side at a loss and then had the other side tested.
Position sizing and risk
Size by the maximum loss per condor using /tools/position-size, and keep the sum of all open condors' maximum losses under the heat cap in /learn/risk-management. Condors on different indices are highly correlated in a crash; count them as one position. Never add a second condor to "average down" a tested one; that doubles the risk on the side the market is moving toward.
What breaks it
- Trending markets. A steady 8 percent grind in one direction over a month walks through the short strike with no volatility spike to sell into, and the loss rule triggers several times in a row.
- Gap risk. A 5 percent gap through a short strike produces a loss near the maximum before any rule can act. The wings are the only protection, and they are why the wings exist.
- Skew. Put wings are richer than call wings; a symmetric-delta condor is not symmetric in dollar risk, and the call side often pays little.
- Costs. Four legs to open, up to four to close; on stocks with 10-cent spreads this can consume a quarter of the credit.
- Edge decay. Condors on the major indices are extremely crowded, and the IV premium has narrowed. High-IV entry filtering is the surviving edge, and it means the program is idle much of the time.
- Drawdowns. A year of small wins can be erased in one bad month; realised equity curves are saw-toothed.
How to test it
Simulate condors on an index ETF over 15 or more years with realistic option pricing, under two conditions: always open, and only when IV rank exceeds 50. The comparison is the test of the thesis. Report win rate, expectancy, profit-factor, worst month and the number of trades (the filtered version will have far fewer, which is correct). Add double costs and see whether it survives. Because the filtered version produces perhaps 20 trades a year, you will need the full history to reach a meaningful sample. Paper-trade for a full IV cycle (a calm period and a scared one) before committing.
Variations
- Unbalanced condor with more put spreads than call spreads, or wider put wings, to match skew.
- Iron butterfly: short strikes at the money; higher credit, narrower profit zone.
- Earnings condor opened the day before an earnings-report and closed the morning after; see earnings-iv-crush.
