An iron condor credit spread combines a put credit spread and a call credit spread on the same underlying asset, with the same expiration. You collect a net premium upfront. In exchange, you accept losses if the underlying moves far enough outside your chosen range.
The attraction is a capped expiration loss and room for the underlying to move without destroying the trade. The catch is that the potential loss can exceed the premium collected. Four legs provide protection, not immunity. Within the broader family of butterfly and condor options spreads, the credit iron condor creates a flat maximum profit zone between two short strikes.
How an Iron Condor Credit Spread Works
A standard credit iron condor uses four options in equal quantities. Reading from the lowest strike to the highest, you buy a put, sell a put, sell a call, then buy a call. Typically, the underlying starts between the two short strikes.
The short put and lower strike long put form a bull put credit spread. The short call and higher strike long call form a bear call credit spread. The purchased options are the protective wings: they cap the expiration losses created by the short options.
For standard, unadjusted equity options, each contract represents 100 shares, so a premium quoted at $1.40 equals $140 per contract. Check the contract deliverable rather than assuming every option uses that convention. Trading also requires the appropriate account approval; FINRA’s options overview covers contract size and trading approval.
A Worked Iron Condor Example
Assume a hypothetical stock trades at $100. You enter the following position, with all four options expiring in 30 days. Premiums are illustrative, not live market quotes.
| Action | Option | Premium per share | Cash flow |
|---|---|---|---|
| Buy one | $90 put | $0.40 | Pay $40 |
| Sell one | $95 put | $1.10 | Receive $110 |
| Sell one | $105 call | $1.00 | Receive $100 |
| Buy one | $110 call | $0.30 | Pay $30 |
The short options bring in $210. The protective options cost $70, leaving a $140 net credit, or $1.40 per share. Both wings are $5 wide: $95 minus $90 on the put side, and $110 minus $105 on the call side.
That $140 is the most the original position can earn before costs. Receiving it does not mean the trade has already made $140. You still hold obligations that may cost more to close than you received.
Maximum Profit, Maximum Loss and Break-Even Prices
For an equal width credit iron condor, the expiration calculations are:
- Maximum profit: net credit × contract multiplier.
- Maximum loss: (wing width − net credit) × contract multiplier.
- Lower break-even: short put strike − net credit per share.
- Upper break-even: short call strike + net credit per share.
The example therefore has a maximum profit of $140, a maximum loss of ($5 − $1.40) × 100 = $360, and break-even prices of $93.60 and $106.40. These relationships match the Options Industry Council’s credit iron condor payoff formulas.
All figures exclude commissions, exchange charges and other costs. The loss cap also assumes the position remains intact and exercise or settlement is handled correctly. It is not a blanket cap on losses from stock positions left behind after expiration.
What Happens at Different Expiration Prices?
Between $95 and $105, all four options have zero intrinsic value at expiration. The position retains its full $140 credit before costs. That is the flat top of the payoff diagram.
At $94, the short $95 put has $100 of intrinsic value and the other options have none. Subtract that $100 from the credit and the trade earns $40. Crossing a short strike does not immediately make the position unprofitable.
At $108, the short $105 call has $300 of intrinsic value, while the long $110 call has none. The result is $140 minus $300, a $160 loss. At $110 or higher, the call spread’s expiration value reaches $500, producing the maximum $360 loss. The same maximum loss applies at $90 or lower through the put spread.
You do not add both wings’ maximum losses together. At one expiration price, the stock cannot finish below the put strikes and above the call strikes simultaneously. Closing or adjusting parts of the trade at different times changes that calculation.
Choosing Short Strikes and Protective Wings
Two distances matter, and they do different jobs. The distance between the short put and short call determines the maximum profit zone. The distance from each short option to its protective long option determines that wing’s width.
Moving the short strikes farther from the stock generally reduces the credit when other terms stay comparable. You gain room for price movement, but receive less compensation. A wide range can look comfortable while offering an unattractive payoff.
Moving the protective options farther away generally increases the credit, but also increases the wing width and potential loss. Compare the extra premium with the extra dollars at risk rather than choosing the largest headline credit. The relationship between strike width, spread risk and reward matters on both sides of the condor.
Unequal wings create unequal downside and upside risks. Calculate each wing’s width minus the total credit separately; the wider wing determines the larger expiration loss.
In the worked example, three maximum profit trades earn $420, while one maximum loss costs $360. That leaves only $60 before trading costs. This is arithmetic, not a forecast, but it shows why a high win rate alone cannot establish whether a strategy is worthwhile.
How Time, Volatility and Price Movement Affect the Position
The expiration payoff is only the destination. Before expiration, the cost of closing the condor depends on the underlying price, remaining time and implied volatility across its four options.
Near the center of its range, a conventional credit iron condor typically has positive theta and negative vega. Time passing can help by reducing its closing value; rising implied volatility can hurt by increasing that value. Delta can start near zero, but it changes as the underlying moves. The OIC’s discussion of Greeks in condors and butterflies covers these exposures and the concentration of gamma risk near short strikes.
These are tendencies, not permanent settings. The purchased options also lose time value, and the net Greeks can change as price moves through the structure. “Positive theta” is not a daily interest payment.
A stock can remain inside the expiration break-even prices while the position shows an unrealized loss. There may still be enough time and uncertainty for one wing to become expensive. Conversely, a fall in implied volatility may allow an early profitable exit without waiting for the options to expire.
Very short expirations compress the decision window. Near the money, small underlying moves can change option exposure rapidly as expiration approaches. Cboe’s same day options risk guidance highlights this sensitivity. Faster time decay comes with faster changes in risk; a same day condor is not simply a monthly trade played at double speed.
Execution Costs Can Change the Trade
Evaluate the condor as a package rather than four attractive looking option quotes. Where available, a multi-leg limit order lets you specify the minimum net credit you will accept. Exchange infrastructure such as Cboe’s complex order book and auction supports packaged execution at a net price.
A limit price does not guarantee a fill. Treat a displayed midpoint as a reference, not promised proceeds. If the example fills at $1.20 instead of $1.40, maximum profit falls to $120 and maximum expiration loss rises to $380. Execution affects both sides of the payoff.
Fees matter too. Suppose a hypothetical fee schedule charges $0.65 per contract. Opening four contracts costs $2.60; closing all four costs another $2.60, before any other charges. A $70 gross trading profit becomes $64.80 after those fees.
Opening the legs separately introduces another problem: until every leg fills, you do not hold the planned condor. Selling short options before obtaining protection can temporarily create a very different exposure. A better quoted credit is not automatically a better trade if obtaining it requires taking unintended risk.
Assignment and Expiration Risks
American style short options can be assigned before expiration. Assignment of a short equity put creates an obligation to buy shares; assignment of a short equity call creates an obligation to deliver them.
Owning a protective option does not automatically resolve that obligation. You may need to close the resulting shares, manage the remaining options, or exercise a long option where appropriate. FINRA’s guidance on assignment in multi-leg strategies makes clear that the investor remains responsible for taking action.
The worked example shows the funding issue. Assignment of the $95 put involves buying 100 shares for $9,500, even though the original condor’s modeled maximum expiration loss was $360. Those numbers describe different things: a share purchase obligation and a spread payoff.
Expiration adds uncertainty when the stock sits close to a short strike. One option may be exercised while its protective wing expires, leaving an unexpected stock position. Price moves after the regular session can also affect exercise decisions.
Review expiration and pin risk in options spreads before deciding to hold through the final session. Check the contract’s settlement method and your broker’s exercise deadlines. The maximum loss diagram cannot manage those details for you.
Closing or Adjusting an Iron Condor
Closing the full position reverses its four legs: buy back the short options and sell the long options. The trading result is the opening credit minus the closing debit, multiplied by the contract multiplier and quantity, then reduced by costs.
If the example opens for $1.40 and closes for $0.70, the gross profit is $70. If closing costs $2.50, the gross loss is $110. Neither outcome requires waiting until expiration.
Set an exit plan before entry. Decide what would justify taking a partial profit, accepting a loss, or closing before an event. Choose the position size using the possible dollar loss, not just the credit received.
Adjustments deserve the same scrutiny as new trades. Closing the untested wing removes that wing but does not eliminate the threatened spread. Moving strikes or expirations changes the exposure and may realize a loss. Closing and rolling an options spread are separate decisions; a new credit does not erase the old result.
Do not sell a protective long option without checking what remains. Removing a wing while keeping its short option open can remove the original loss cap.
Iron Condor Versus Iron Butterfly
The credit iron condor separates its short put and short call strikes. An iron butterfly credit spread places both short options at the same strike, creating a single maximum profit point rather than a flat maximum profit zone.
Neither structure is automatically better. Compare the actual credit, break-even prices, potential loss and execution costs. The iron condor is useful for expressing a range view with protective wings, but its value depends on the price received for accepting that risk. A comfortable looking range is only part of the decision.
