The Iron Condor: Four Legs, One Bet

An iron condor is selling a call spread and a put spread at the same expiry, collecting both credits. It profits if the underlying stays between the two short strikes, and the outer legs cap what an escape from that range can cost.

How it works

The underlying price swept from low to high above, and the profit and loss of an iron condor at expiry below, with both breakevens marked. The headline on the chart reads: Four legs that pay if price stays in a range.

Sell a call spread above the price and a put spread below it, same expiry. Four legs: two sold near the money, two bought further out.

Collect both credits. If price finishes between the two short strikes, everything expires worthless and the credits are kept. That is the whole intention.

The payoff is a plateau with two cliffs. Flat and profitable in the middle, falling away on both sides, then flat again once the bought legs take over.

The underlying swept from low to high above, with a put credit spread payoff below. The headline on the chart reads: The outer legs cap the loss and cost part of the credit.

Those outer legs are the difference between this and a short strangle. They cost part of the credit and they convert an open-ended loss into a known one.

The four strikes, and the two figures that matter

Short strikes at 95 and 105, long strikes at 85 and 115, total credit 3:

Maximum gain +3 — the credit, if price finishes between 95 and 105
Maximum loss −7 — the 10-point wing width minus the 3 credit
Lower breakeven 92 — the short put strike minus the credit
Upper breakeven 108 — the short call strike plus the credit

+3 against −7 is the same ratio as a single credit spread, because that is what this is — two of them, of which only one can lose. Price cannot finish above 115 and below 85 at the same time.

Which means the position needs to win roughly 70% of the time to break even before costs. A high win rate is the entry requirement here, not evidence of skill.

In practice: a bet on nothing happening

The underlying swept from low to high above, with a theta curve below. The headline on the chart reads: It is a bet on time passing and nothing happening.

It is a bet on time passing. Theta is the entire income, and the position profits from days going by rather than from anything being correct about direction.

A flat, quiet stretch of the long price series with an extrinsic-value curve decaying below it. The headline on the chart reads: And the profit arrives slowly, if it arrives.

And it arrives unevenly. Half the days gone leaves 70% of the extrinsic value, so most of the credit is earned in the second half — which is also when a breach is most damaging.

The underlying swept from low to high above, with a gamma curve below. The headline on the chart reads: Near expiry, small moves change the position fast.

Gamma rises into the end. In the final week, a move of a couple of points can take the position from most of its profit to most of its loss, which is why many people close early and give up the last portion deliberately.

A sideways, range-bound candlestick series. The headline on the chart reads: The market it wants is the one nobody likes trading.

The ideal market is the dullest available. Sideways, low volatility, nothing scheduled. That is a real market condition and it is also the one in which the credits on offer are smallest.

What an iron condor is not

It is not neutral. It is a position that loses if price moves much in either direction, which is a strong opinion about range rather than an absence of opinion.

It is not high-probability in a useful sense. The probability is high because the payoff is poor, and the pricing sets one against the other.

It is not passive. The defined maximum loss is only defined if all four legs remain in place, and early assignment on a short leg breaks that temporarily.

And it is not four independent trades. It is one position, and treating the legs separately is how people end up closing the profitable side and holding the exposed one.

When it fails

A strongly rising stretch of the long price series. The headline on the chart reads: One strong trend undoes many quiet weeks.

One sustained trend undoes many quiet weeks. At +3 and −7, a single full loss removes more than two full wins, and the trend that produces it is the market’s most ordinary behaviour.

A flat but volatile stretch of the long price series. The headline on the chart reads: And a breakout is the whole risk in one event.

A breakout concentrates the entire risk into one event, and the outer legs are the only reason it is finite.

Costs are the heaviest of any structure here. Four legs to open and four to close is eight option spreads against a maximum gain of 3, on top of the 2% of a typical bar the underlying costs.

Adjusting a threatened side is the fourth failure. Rolling the breached spread further out collects more credit and increases the maximum loss, converting a defined outcome into a larger position with a later deadline.

Selling condors into low volatility is the fifth. The credits are smallest when the market is calmest, so the position collects the least for the same defined risk in exactly the conditions it prefers.

And judging it on a quarter is the sixth. A run of wins is what this structure produces even without an edge. The interval that contains information is one that includes at least one breach.

A seventh is running the same expiry across many correlated names. Ten condors on ten large technology companies is one position wearing ten labels, because whatever breaks one range tends to break the others in the same session.

None of this makes the structure unusable. It has a genuinely defined maximum loss, it profits from the most common market condition, and every number in it is known before the position is opened — which is more than can be said for most things people trade. The honest description is that it converts a wide, uncertain distribution into a narrow, well-understood one with a poor payoff ratio, and whether that is worth doing depends on being right about range far more often than the marketing around it suggests.

The original data

7 of the 24,971 videos measured for this site cover iron condors, at a median of 5,660 views — a small supply and a modest median, and most of it presents the win rate without the ratio that makes the win rate necessary.

The +3 against −7 and the breakevens at 92 and 108 were computed from the stated contract. Working those four numbers out before opening a position takes about a minute and turns “high probability income” into a description anyone can evaluate: a small win, a larger loss, and a win rate that has to clear 70% before the structure has done anything for you.

Credit spreads is the half of this worked through in full. Strangles is what this becomes without the outer legs. And theta is the mechanism the entire position depends on.

What I actually do

The iron condor was the strategy that most made me feel like I was running a business, and the numbers said otherwise. Lots of small wins is a very persuasive experience and it is not the same as an edge.
