An iron condor gives you a wider profit zone and a smaller credit. An iron butterfly gives you a bigger credit and a much narrower profit zone. Both are defined-risk, net-credit trades that pay off when the underlying stays quiet. The real choice is how confident you are about where price will finish, and how much of that confidence you want to be paid for.
This guide builds both trades with worked numbers, compares them on the criteria that matter, and covers the risks and management habits that apply to each. It also covers the decision process behind the pick, because most losses in these trades come from how they are chosen and handled, not from the structure.
TL;DR
- An iron condor sells an out-of-the-money put spread and call spread. An iron butterfly sells the at-the-money put and call and buys wings on both sides.
- The condor has a wider profit range and a smaller credit. The butterfly has a larger credit and a narrow peak at the middle strike.
- Both are generally theta-positive near the short strikes, and both are hurt by rising implied volatility and by price moving toward the wings.
- Pick the condor when you expect a range. Pick the butterfly when you expect price to pin near one level.
- Write down your exit rules before entry. A structure does not protect you from skipping them.

How the two trades are built
Both strategies combine a bull put spread and a bear call spread on the same underlying and the same expiration. The difference is where the short strikes sit.
Iron condor. You sell a call credit spread and a put credit spread using out-of-the-money options. The payoff is a capped-profit plateau between the short strikes, with capped losses beyond the long wings, as described in the Options Clearing Corporation's guide to condors and butterflies. Its worked example sells the 90/95 call spread and the 85/80 put spread with the stock at $88.50, for a $3.05 net credit.
Iron butterfly. You sell a call and a put at the same middle strike, then buy an out-of-the-money call and put as protection. The Options Industry Council describes it as effectively a short at-the-money straddle protected by out-of-the-money wings. It is a credit spread built from a bear call spread and a bull put spread at the middle strike. A basic butterfly is a debit spread, and the iron version uses four contracts instead of three.
A quick way to remember it: a condor has four different strikes. An iron butterfly has three, because the two short options share one.
Side-by-side comparison
| Feature | Iron condor | Iron butterfly |
|---|---|---|
| Short strikes | Two, out of the money | One, at the money |
| Number of strikes | Four | Three |
| Net credit | Smaller | Larger |
| Profit zone at expiration | Wide plateau | Narrow peak at the middle strike |
| Maximum profit needs | Price between the short strikes | Price at the middle strike |
| Maximum loss | Wing width minus credit | Wing width minus credit |
| Outlook | Range-bound, price stays inside a band | Price pins near one level |
| Probability of some profit | Higher | Lower |
| Reward relative to risk | Lower | Higher |
The last two rows are the trade-off in one line. The butterfly pays more for being right about a precise level. The condor pays less but is right more often.
Worked numbers: same stock, two structures
The OCC's condor example is a good anchor. With XYZ at $88.50 and a $3.05 credit, the maximum gain is $3.05, the maximum risk is $1.95, and the expiration breakevens are $81.95 and $93.05, before transaction costs.
To see the butterfly next to it, here is an illustrative setup of our own. The prices are hypothetical, not quotes. Assume a stock at $100 and a $5 wing width on both trades.
Iron condor (hypothetical): buy the 90 put, sell the 95 put, sell the 105 call, buy the 110 call, for a $1.50 credit.
- Maximum profit: $1.50 per share ($150 per contract), if the stock finishes between 95 and 105.
- Maximum loss: $3.50 per share ($350 per contract), if it finishes below 90 or above 110.
- Breakevens: $93.50 and $106.50.
Iron butterfly (hypothetical): buy the 95 put, sell the 100 put, sell the 100 call, buy the 105 call, for a $3.50 credit.
- Maximum profit: $3.50 per share ($350 per contract), only if the stock finishes exactly at 100.
- Maximum loss: $1.50 per share ($150 per contract), if it finishes below 95 or above 105.
- Breakevens: $96.50 and $103.50.
The condor profits across a $13 band of breakevens. The butterfly's band is $7. In exchange, the butterfly collects more than twice the credit and risks less than half as much. Each trade's maximum profit and maximum loss add up to the wing width, so the credit you take decides how the risk is split.
In practice, the butterfly's maximum profit is rarely reached. Most outcomes land somewhere on the slope between the middle strike and a breakeven, which means partial profit or partial loss. Plan around that slope, not the peak.
What each trade assumes about the market
Both trades are net-credit structures that sell option premium. The Options Industry Council says the condor suits selling elevated premium when implied volatility is relatively high, with the long wings limiting risk. The credit version of the iron butterfly also suits elevated volatility, but maximum profit requires the stock to close at the middle strike.
Translate that into outlooks:
- Condor: "I expect price to stay within a range, and I do not know where inside it."
- Butterfly: "I expect price to settle near a specific level, such as a round number, a heavily traded strike, or the level price has gravitated to before an event passes."
If you cannot name the level in the butterfly's case, the condor is the more honest expression of your view.
How to choose between them
Use these criteria in order.
- How precise is your view? A range calls for the condor. A single pin level calls for the butterfly.
- How much do you want to be paid versus how often you want to win? The condor leans toward frequency. The butterfly leans toward payoff size.
- Where is implied volatility? Both trades benefit when it falls and suffer when it rises, so entering when it is relatively high matches how both are designed.
- How much room does the stock have? Compare your short strikes to the stock's recent movement. A condor whose short strikes sit inside the typical weekly move is a butterfly with extra steps and less credit.
- What size can you afford to lose? Because maximum loss is wing width minus credit, you can calculate it before entry. Size so that the full loss is a small fraction of the account.
On sizing, our guide to sizing trades to 1 to 2 percent with an options risk graph walks through the arithmetic.
Risks that apply to both
Time decay is not a constant ally. The Options Industry Council characterizes condors and butterflies as generally theta-positive while price stays near the short strikes. It also notes that time decay can turn against the position as price approaches the outer wings. Once you are testing a wing, waiting is no longer the same as earning.
Volatility cuts both ways. Falling implied volatility helps these positions and rising volatility hurts them. A sudden jump in volatility can show a loss on paper before price has moved much.
Early assignment. For American-style options, short legs can be assigned before expiration. The U.S. Options Course notes this is most likely for short calls ahead of ex-dividend dates when remaining time value is below the dividend, and for deep in-the-money short puts with little extrinsic value. Check dividend dates before holding short calls on dividend-paying stocks.
Pin risk at expiration. The same source describes pin risk: if the underlying closes near a short strike, assignment may be uncertain after the close and can leave an unhedged stock position over the weekend. The butterfly sits exactly on this zone by design, since its short strikes are at the money. If you are holding either trade into the final day, talk with your broker about its exercise and assignment procedures. A related guide recommends closing short legs within 1% of the current price before the expiration-day close.
Multiple legs, multiple costs. Four options mean four commissions and four bid-ask spreads. Wide spreads on illiquid strikes can eat a large share of a small condor credit, so check the quoted net credit against the mid price before you enter.
So, how risky is an iron condor? Its maximum loss is defined and known at entry. But the loss is usually larger than the maximum profit, so a few full losses can erase many small wins. That is why exits matter as much as entries.
Managing the trade after entry
Your management plan should exist before the order does. Three questions cover most of it.
- What is my profit exit? Many traders close before expiration instead of waiting for the last dollar of credit. Define the percent of credit you will take.
- What is my loss exit? Decide the price level or loss multiple that ends the trade, and what you will do if the short strike is touched.
- What is my time exit? Gamma and pin risk grow into expiration. Our theta decay management rules for the final 30 days cover this window.
For condors in particular, see our iron condor management rules and adjustments. If you are considering rolling a tested side, timing rules for rolling options and the options trade adjustments checklist help you decide whether a change is a plan or a reaction. Our trade exit rules guide shows how to fix those exits in advance.
The most common failure is not a bad structure. It is a trader who moves a stop, widens a wing, or doubles down on a tested side to avoid taking a loss. If that sounds familiar, read trading after a loss before your next entry.
A short pre-trade checklist
- State the outlook in one sentence: range or pin level.
- Check implied volatility relative to its recent history.
- Choose strikes and confirm both maximum profit and maximum loss in dollars.
- Confirm the loss is within your per-trade limit.
- Check dividend dates and the expiration schedule.
- Write the profit, loss and time exits.
- Log the reason for the trade, so you can review it later.
For a fuller process, our options trade analysis workflow turns these steps into a repeatable routine.
Our perspective
Traders ask whether the butterfly or the condor is better, and the honest answer is that the structure is the smaller part of the decision. Two traders can open the same condor. One has a written exit and a position size that fits the account. The other is hoping. They do not have the same trade.
At EI ALGOS we built our platform around that gap. We do not issue signals or tell you which structure to open. Our six-factor engine scores each setup on the psychological and behavioral factors behind the decision, so you can see whether you are entering with a plan or chasing a credit.
Over time, LIANA, our assistant, helps you see patterns in your own process. Maybe you sell condors tighter after a losing week. Maybe you hold butterflies into the last day against your own rules. Those are behavior patterns, and they are fixable once you can see them.
Choose the structure that matches your view. Then judge yourself on whether you followed your process.

FAQ
Is an iron butterfly better than an iron condor?
Neither is better in general. The butterfly pays a larger credit but needs price to finish close to the middle strike. The condor pays less but gives you a wider range. Choose by how precise your view is and how much risk of a partial loss you accept.
How risky is an iron condor?
Its maximum loss is fixed at entry: the wing width minus the credit received. Because that loss usually exceeds the maximum profit, a few full losses can outweigh many small gains. Risks such as early assignment, rising volatility and pin risk also apply, so size small and set exits first.
Why would you use a butterfly spread?
Traders use a butterfly when they expect price to settle near a specific level and want a defined-risk way to be paid for that view. A standard butterfly is a debit trade. The iron version collects a credit and uses four contracts instead of three.
What is the opposite of an iron condor?
A long iron condor, which buys the inner strikes and sells the outer ones, reverses the payoff. It is a net-debit trade that profits when price moves beyond the outer breakevens. It suits a trader expecting a large move, not a quiet market.
