What Is an Iron Condor?

Range-bound income, and its risk profile.

An iron condor is a four-leg options strategy designed to collect premium when you expect an underlying to stay within a defined range through expiration. You sell an out-of-the-money put spread and simultaneously sell an out-of-the-money call spread on the same underlying and expiration — four strikes, all defined risk, all in one trade. The position profits when the underlying finishes between the two short strikes, and it loses when the market moves far enough to breach either wing. Before sizing any condor, model the exact credit and break-evens with an options pricing calculator to confirm the numbers match your thesis; what looks like a wide tent on a chart can be surprisingly narrow once you run the precise arithmetic.

How the iron condor is structured

The four legs, from lowest strike to highest:

1. Long put at the lowest strike (the floor of the lower wing)
2. Short put at a higher strike, out of the money (the lower short strike)
3. Short call at a higher strike, out of the money (the upper short strike)
4. Long call at the highest strike (the ceiling of the upper wing)

The two short options generate premium; the two long options cap the maximum loss. The position is entered for a net credit — you receive cash upfront. The spread widths on both wings are typically equal, though they don't have to be.

An iron condor differs from a strangle in one critical respect: the strangle has unlimited risk on both sides, while the condor's long options create hard loss caps. That defined-risk structure makes condors easier to size and hold through volatility spikes without panic-liquidating.

Profit, loss, and break-evens

The payoff math is straightforward once you pin down the net credit received:

• Max profit = net credit received (both spreads expire worthless)
• Max loss = spread width − net credit (one side goes fully in the money)
• Lower break-even = short put strike − net credit
• Upper break-even = short call strike + net credit

If the spreads are $5 wide and you collect $1.50 net credit, max loss is $3.50 and you need only $1.50 of protection to stay profitable — but you can lose more than twice what you stand to make on any single trade. That asymmetry is the defining feature of the strategy, and it is why a high win rate alone does not guarantee edge. A trader who wins 75% of condors at $1.50 but loses $3.50 on every loss breaks even before costs; the edge has to come from strike selection and timing, not from raw frequency of wins.

Visualising the full tent-shaped payoff across a range of underlying prices makes the relationship clearer — see payoff diagrams for a walkthrough of how the four legs combine.

The Greek profile: what you own when you sell a condor

An iron condor is a short-volatility trade. The Greek exposures at initiation tell you exactly what conditions it needs to make money:

• Theta positive. Time decay works in your favour. Every day that passes without a large move erodes the value of the options you are short, and your P&L drifts upward toward the max credit.
• Gamma negative. Large moves in either direction hurt you. Gamma accelerates the losses on the short options faster than the long options protect you when the underlying is near a short strike.
• Vega negative. A rise in implied volatility increases the value of all four legs, but the short legs dominate — so an IV spike means mark-to-market losses even if the underlying hasn't moved at all.
• Delta near zero. At initiation the position is roughly market-neutral, though delta will drift as the underlying moves toward one of the short strikes.

The condor earns theta every day the underlying stays calm. It bleeds when the market gaps, trends hard, or when implied volatility expands. Entering condors when IV is elevated — so you're selling expensive premium — and exiting before expiration to avoid gamma risk near the short strikes is the practical expression of this Greek profile.

Worked example

Suppose SPY is trading at $540. You sell a 30-day iron condor with $5-wide wings:

Leg	Strike	Action	Premium
Long put	510	Buy	−$0.40
Short put	515	Sell	+$0.85
Short call	565	Sell	+$0.90
Long call	570	Buy	−$0.45
Net credit			+$0.90

Max profit: $0.90 per share ($90 per contract). Max loss: $5.00 − $0.90 = $4.10 per share ($410 per contract). Lower break-even: 515 − 0.90 = $514.10. Upper break-even: 565 + 0.90 = $565.90. SPY must close between $514.10 and $565.90 at expiration for any profit. That's a $51.80 profit zone on a $540 underlying — roughly ±4.8% — before you collect a cent. Breaching either wing by the full $5 costs $4.10, more than four times the credit.

Managing the trade

Most experienced condor traders do not hold to expiration. Managing the position actively narrows the distribution of outcomes in ways that mechanical rules capture well:

• Take profits early. Closing the position when it has decayed to 25–50% of the original credit locks in gains and eliminates the outsized gamma risk in the final two weeks before expiration, when short options can move violently on relatively small underlying moves.
• Define a loss limit. A common rule is to close if the position reaches two times the original credit in unrealised losses ($1.80 in the example above). Cutting at a pre-defined level prevents the rare large move from wiping out many months of collected premium.
• Rolling a threatened wing. If the underlying drifts toward one short strike, you can buy back that spread and re-sell it further out of the money — collecting additional credit and buying distance. Rolling works best when there is still enough time value in the new strikes to justify the trade and when implied volatility is not collapsing simultaneously.
• Adjusting width and strike distance. Wider wings produce larger credits but narrower break-even zones as a percentage of spread width; the tradeoff is always between credit collected and range afforded.

The iron condor is not a passive set-and-forget structure. Sizing it small enough to survive the inevitable loss, entering when implied volatility is relatively high, and exiting before expiration gamma dominates — those are the operational decisions that separate disciplined execution from a strategy that merely looks good on a backtest.
