Iron Butterfly vs Iron Condor: Credit, Risk and Which One Fits Your Account in 2026

An iron butterfly and an iron condor are the same trade with one setting changed. Both sell a call and a put and buy a further call and a further put for protection. The iron butterfly sells both options at the same strike. The iron condor sells them at two different strikes with a gap in between.

That one change moves everything else. The iron butterfly collects more premium and needs the stock to finish almost exactly where it started. The iron condor collects less and gives the stock room to move. Traders often pick between them by which credit looks bigger, and that is the wrong number to choose by.

In this guide we'll cover how each structure is built, how the credit, maximum loss and breakevens compare on the same stock, how the two behave before expiration, which conditions suit each one, and how an iron butterfly or an iron condor fits inside a simulated funded options account with a fixed daily loss limit.

Key Takeaways

• Treat them as one family. An iron butterfly is an iron condor with the two short strikes moved together. Everything else follows from that.
• Compare the maximum loss, not the credit. The iron butterfly's larger credit comes with a much narrower range in which you keep any of it.
• Size from the worst case. The most you can lose per contract is the width of one wing minus the credit. That figure, not the premium collected, goes against your daily loss limit.
• Expect a different trade before expiration. The payoff diagram shows expiration day. An intraday trader closes long before that and is trading the change in the position's price.
• Count four spreads on the way in and four on the way out. Both structures have four legs, and the cost of crossing eight bid-ask spreads is paid whether the idea works or not.

What is the difference between an iron butterfly and an iron condor?

The difference is where the two short options sit. In an iron butterfly, the short call and the short put share one strike, usually at the current stock price. In an iron condor, the short call sits above the stock price and the short put sits below it. Both are four-leg, defined-risk positions opened for a credit.

The iron butterfly, leg by leg

The Options Industry Council's page on the short iron butterfly describes it as "long a call at an upper strike, short a call and short a put at a middle strike, and long a put at a lower strike." The middle strike is the body. The outer strikes are the wings, and they sit the same distance from the body.

A note on names. The Options Industry Council calls the version you open for a credit the "short" iron butterfly. Most traders and most platforms simply call it an iron butterfly, or an iron fly. This guide uses the everyday name for the credit version throughout.

The same page gives a second way to see it: "a short straddle surrounded by a long strangle." You have sold the at-the-money call and put, which is where the premium is richest, and bought cheaper options further out so that the loss has a ceiling.

The iron condor, leg by leg

The council's page on the iron condor describes the build this way: "the investor sells one call while buying another call with a higher strike and sells one put while buying another put with a lower strike." Typically the call strikes are above the stock and the put strikes are below it.

The council also states the family relationship directly. The condor "is a variation of the short iron butterfly. Instead of a body and two wings, the body has been split into two different strikes." Our guide to iron condors in a funded account covers that structure on its own in more depth.

Two credit spreads, either way

Both structures can be read as a pair of vertical credit spreads. The council says each "could also be considered as a bear call spread and a bull put spread." The call spread loses if the stock rises too far. The put spread loses if it falls too far. The stock cannot be above the call strikes and below the put strikes at once, so at expiration only one side can be at its maximum loss.

That is why the risk on the whole position is the width of one wing, not two.

How do the credit, risk and breakevens compare?

On the same stock with the same wing width, the iron butterfly collects a larger credit, has a smaller maximum loss and has a much narrower profit range. The iron condor collects less, risks more per contract and stays profitable across a wider range of prices. Neither is cheaper. They charge for different things.

One stock, both structures

Here is an illustrative example. The stock is at $100 and every wing is $5 wide. The premiums are invented to show the arithmetic, and an option contract generally covers 100 shares, so a $3.00 credit is $300 per contract.

• Iron butterfly. Sell the 100 call and the 100 put. Buy the 105 call and the 95 put. Net credit: $3.00, or $300.
• Iron condor. Sell the 105 call and the 95 put. Buy the 110 call and the 90 put. Net credit: $1.50, or $150.

The maximum gain on each is the credit. The council's pages give the maximum loss for both as the distance between the strikes of one spread, less "the premium received for initiating the position." For the butterfly that is $5.00 minus $3.00, or $200 per contract. For the condor it is $5.00 minus $1.50, or $350.

The breakevens sit one credit away from the short strikes. For the butterfly that is $97 and $103, a range of $6. For the condor it is $93.50 and $106.50, a range of $13.

The same closing prices, side by side

The table below takes the two positions from the example to expiration at five closing prices. The pattern is the same for the matching prices below $100.

Profit and loss per contract at expiration for the illustrative iron butterfly ($3.00 credit) and iron condor ($1.50 credit), both with $5 wings on a $100 stock, before commissions and fees.

What the bigger credit is paying you for

The butterfly looks better on two lines and worse on one. It collects twice the credit and risks less. But the full $300 is only kept if the stock closes at exactly $100, which almost never happens. A trader who sells a butterfly is really expecting to keep a part of the credit, and how large a part depends on how close the stock finishes to the body.

The condor's $150 is kept in full anywhere between $95 and $105. It pays less because the outcome it needs is more likely. Our guide to probability of profit covers why a high chance of a small gain and a low chance of a large one can be worth the same.

How do they behave before expiration?

Before expiration, both positions gain from the passage of time and from falling implied volatility, and both lose when the stock moves quickly. The iron butterfly reacts more sharply to all three, because its short options sit at the money, where option prices are most sensitive.

Time decay

The council's pages say the same thing about both structures: "The passage of time, all other things equal, will have a positive effect on this strategy." You sold more premium than you bought, and that premium shrinks as expiration approaches if the stock stays put.

The butterfly holds more premium, so it has more to decay. That is an advantage if the stock sits still and no help at all if it does not.

Implied volatility

Again from both pages: "An increase in implied volatility, all other things equal, would have a negative impact on this strategy." A rise in implied volatility lifts the price of every option in the position, and because you are a net seller, the position costs more to buy back.

This is why traders tend to open these positions when implied volatility is high and they expect it to fall. Our guide to implied vs realized volatility explains how to judge whether the premium on offer is rich or thin.

Price movement

This is the largest difference between the two. A condor opened with the stock midway between the short strikes starts with a wide flat area. A small move in the stock changes its value only a little. A butterfly has no flat area. Its short strike is the stock price, so every move away from the body begins to cost money at once.

Near expiration the effect grows. The butterfly's value can swing hard on a move of a few cents around the body. Our guide to butterfly spreads covers that expiration-day behavior for the whole butterfly family.

The diagram is not the trade you will have today

Payoff diagrams show expiration. If you open either position with three weeks to run and close it the same afternoon, you will see only a fraction of the credit as profit even if the stock does nothing. You can also see a loss well short of the maximum if the stock moves against you. An intraday trader in these structures is trading a small change in a four-leg price, not the shape in the picture.

When does each one fit?

An iron butterfly fits a trader who expects the stock to stay very close to one price and wants the largest credit for being right. An iron condor fits a trader who expects a range and wants room for error. If you cannot say which of those you believe, the condor is the more forgiving choice.

When the butterfly makes sense

The butterfly suits a specific view: the stock has a reason to stay near one price. It also suits traders who plan to take a partial profit early and leave, since the larger credit gives more to work with. The damaging admission is that a butterfly is wrong more often than a condor. It trades frequency for size.

When the condor makes sense

The condor suits a broader view: the stock will stay inside a range, and you do not need to know where in the range. The trade-off is in the table above. When a condor is wrong, it is more wrong. In the example it loses $350 to make $150, so one maximum loss takes back more than two full wins.

The middle ground

The choice is a dial, not a switch. Move the short strikes of a condor closer together and it collects more and gets narrower. Move them apart and it collects less and gets wider. Wing width is a second dial. Wider wings raise both the credit and the maximum loss. Many of the positions traders actually take sit somewhere between the two textbook shapes.

Iron butterfly vs iron condor in a simulated funded options account

In a simulated funded options account, the choice between an iron butterfly and an iron condor comes down to how each one's maximum loss fits your daily loss limit and how each behaves within a single session. Both structures are supported in TradeFundrr's options accounts. The limits are the same whichever you pick.

What the account allows

TradeFundrr's options accounts come in two forms: Pre-Prop, a simulated evaluation account, and Prop. The published rules for both say that outright long calls and puts, spreads, iron condors and butterflies are supported, and that credit-based positions are allowed up to account buying power. Both start with $25,000 in buying power. A limit on contracts per leg applies and differs between the two accounts, so confirm the current figure in your own account terms.

The platform shows option chains, Greeks and implied volatility, and it takes multi-leg orders. Confirm the current symbol list with support, and read your account's rules on multi-leg orders and fills before you rely on a price.

Size from the maximum loss

Both accounts carry a $1,000 daily loss limit and a $3,000 maximum drawdown. Reaching the daily loss limit pauses trading for the rest of the session, and the limit resets the next trading day. The drawdown trails your highest end-of-day balance, and reaching it closes the account. A paused day still counts against the drawdown.

Set the example against those numbers. Five contracts of the butterfly carry a maximum loss of $1,000, which is the whole daily limit in one position. Two contracts of the condor carry $700. Three carry $1,050, which is more than a day allows. The credit tells you none of this. The wing width minus the credit tells you all of it.

A defined-risk trade is not a small-risk trade. "Defined" means the loss has a ceiling. It does not mean the ceiling is below your limit.

The session is the timeframe

TradeFundrr's options accounts are for manual intraday trading only. The published trading hours run from 9:30 a.m. to 3:55 p.m. ET, Monday through Friday, with no swing positions and a 15-second minimum hold. A position opened today is closed today.

That shapes the exit. You are closing a four-leg position before the cutoff, so check that the legs you chose are liquid enough to exit. Ask support how a position still open at the end of the session is handled.

Assignment is a live-market event

In a live account, the short options in both structures carry assignment risk. The council's butterfly page says the short options "are subject to exercise at any time," and that if the stock is near the body at expiration, "the investor faces uncertainty as to whether or not they will be assigned." The SEC's Introduction to Options bulletin describes assignment as a notice telling the seller "that he or she must fulfill the obligation to buy or sell the underlying stock at the strike price."

None of that occurs in a simulated account. No real option is written and no real counterparty can exercise, because no real trade is executed. Nobody delivers shares and nobody wakes up long or short stock on Monday. What matters in the simulation is the price of the position while you hold it and the price at which you close it. Our guide to assignment risk for funded options covers this in full.

It is still a live-ready skill. A trader who learns to close short options before expiration, and not to sit on a butterfly whose body is at the money in the final minutes, has built a habit that matters a great deal once real contracts are involved.

The honest limit of this idea

This is not for everyone. Four-leg positions cost more to enter and exit than they appear to, and selling premium produces many small wins and an occasional large loss. Most traders who struggle with these structures do not lose because they picked the wrong one. They lose because they sized from the credit.

Knowing the difference between an iron butterfly and an iron condor will not guarantee a profitable trade, a passed evaluation or a payout. It tells you what you are being paid for and what you are risking to collect it.

Frequently Asked Questions

What is the difference between an iron butterfly and an iron condor?

An iron butterfly sells a call and a put at the same strike, while an iron condor sells them at two different strikes with a gap between. Both buy a further call and put for protection. The butterfly collects more credit and has a narrower profit range.

Which is safer, an iron butterfly or an iron condor?

Neither is safer in every sense. With the same wing width, the iron butterfly has a smaller maximum loss per contract, but the iron condor stays profitable across a wider range of prices. The butterfly loses less when wrong and is wrong more often.

What is the maximum loss on an iron butterfly?

The maximum loss on an iron butterfly is the width of one wing minus the net credit received, times 100 per contract. With $5 wings and a $3.00 credit, that is $200 per contract, before commissions and fees.

Is an iron butterfly the same as a butterfly spread?

No, though the payoff at expiration is similar. A standard butterfly uses all calls or all puts and is usually opened for a debit. An iron butterfly uses both calls and puts and is opened for a credit.

Can I trade iron butterflies and iron condors in a TradeFundrr options account?

Yes. TradeFundrr's published options rules say spreads, iron condors and butterflies are supported, and credit-based positions are allowed up to account buying power. A per-leg contract limit applies, so confirm the current figure in your own account terms.

How many contracts can I trade under a $1,000 daily loss limit?

Work it out from the maximum loss per contract, not the credit. If one contract can lose $200, five contracts can lose the full $1,000. Most traders use a fraction of the limit on a single position, and your account's contract limit also applies.

Can I be assigned on an iron condor in a simulated funded account?

No. Assignment is a live-market event in which a real option holder exercises against a real seller. In a simulated account no real trade is executed, so nobody is assigned. Your result comes from the prices at which you open and close.

Can I hold an iron butterfly to expiration in a TradeFundrr options account?

Plan on closing it instead. The accounts are intraday only, with published trading hours ending at 3:55 p.m. ET and no swing positions. Ask support how a position still open at the end of the session is handled.

The iron butterfly and the iron condor are one idea at two settings. The butterfly sells the most premium and asks the stock to stay still. The condor sells less and gives the stock room.

Choose by your view and by your maximum loss, not by the size of the credit. Then set the number of contracts so that the worst case is a loss your account can absorb on an ordinary day.
