Four-Leg Expiration & IV Scenarios

Free Iron Condor Strategy Calculator

An iron condor strategy sells a put and call at different strikes and buys outer wings. Calculate net credit after fees, two breakevens and each wing's loss, then test how time and IV change the cost to close before expiration.

Iron Condor Parameters

Standard 100-share contracts only. Premiums are USD per share; loaded premiums use daily closes, which can be stale. Available chain results are limited to 250 per side; later pages are not loaded, so the expiry list can be incomplete. The underlying quote and daily option closes can have different observation times.

Four times this amount is deducted for each condor. Include opening and planned closing fees; use the same fee budget for both scenarios.

Theoretical closing debit uses remaining calendar days / 365, zero dividends and one common IV from the two short legs. A +20% relative change takes 25% IV to 30% IV.

Four legs, two wing widths

A short iron condor combines a bull put spread with a bear call spread on one underlying and expiration. Its short put strike is below its short call strike. A shared short strike instead creates an iron butterfly. The interval between the two short strikes is the maximum-profit region at expiration.

The hypothetical example below uses one contract per leg, a 100-share multiplier, a $100 underlying and a $0.65 fee budget per leg. The put wing is $5 wide; the call wing is $10 wide. Click "Load unequal-wing example" above to reproduce it.

Synthetic entry premiums, USD per share
LegStrikePremiumCash flow
Buy put$90$0.40-$40
Sell put$95$1.30+$130
Sell call$105$1.50+$150
Buy call$115$0.20-$20

Gross credit = 1.30 + 1.50 - 0.40 - 0.20 = $2.20/share, or $220. Fees = 4 × $0.65 = $2.60. Effective credit C = $2.174/share; maximum expiration profit = $217.40. Lower breakeven = 95 - 2.174 = $92.826; upper breakeven = 105 + 2.174 = $107.174. Displayed prices round to cents; calculations retain precision.

Put-side expiration loss = (5 - 2.174) × 100 = $282.60 at or below $90. Call-side loss = (10 - 2.174) × 100 = $782.60 at or above $115. The wider call wing determines maximum loss, so the two outer tails are not equally risky.

P/L(S) = 100 × contracts × [C + max(90 - S, 0) - max(95 - S, 0) - max(S - 105, 0) + max(S - 115, 0)]

At S = $93, the long put is worth $0, the short put costs $2, and both calls expire worthless. P/L = (2.174 - 2) × 100 = $17.40. At $100 it is $217.40; at $110 it is -$282.60. These are expiration cash flows, not a historical backtest.

Why IV changes the exit before expiration

Hold the same entry premiums and $100 underlying fixed. Start with 30 calendar days to expiry, then set days elapsed to 15, risk-free rate to 0% and common IV to 25%. The example applies that IV to all four European-style option valuations and assumes no dividends. Scenario P/L = $217.40 minus the modeled closing debit.

0%25%$82.86$134.54

Time and volatility affect the debit to close, even when the underlying does not move. At expiration, all three IV scenarios converge to the same intrinsic-value payoff. This model uses one flat IV; actual legs can have different IVs, spreads, liquidity and exercise behavior.

Inputs that invalidate the usual two-breakeven picture

  • Use one expiration and equal quantities, with long put < short put < short call < long call. Mixed expiries require a different valuation and settlement analysis.
  • A net debit, or fees that consume the credit, removes the positive maximum-profit region. This calculator stops instead of displaying credit-condor breakevens.
  • If the credit reaches the narrower wing width, that side may have no outer loss region. The familiar two-breakeven formula is then invalid. This tool rejects that input; it is not proof that every asymmetric structure with such a credit is impossible.
  • Daily closes may come from different trading times. Verify all four bid/ask quotes, expiry, deliverable and fees together. American-style assignment can leave stock exposure; expiration payoff limits do not model that path, slippage or financing.

Rebuild the structure in TradingView Options

In TradingView Options, start with Iron Condor or create a strategy, add the four buy/sell positions, and check each strike, expiry, size and entry price. Compare the expiry payoff with a what-if scenario that changes time and IV. TradingView supports custom multi-leg structures; this page deliberately restricts the inputs to one standard credit-condor shape.

Use Pineify AI Stocks & Options Picker to inspect available options-chain inputs. In Trading Journal, keep a plan or note with the four premiums, quote time, fee budget, expected range and exit condition. This is a manual research record, not an automatic four-leg historical backtest or an execution guarantee.

Educational model, not investment advice. A model probability is conditional on its distribution and IV assumptions; it is not a measured win rate or a promise of profit.

Frequently Asked Questions

How is an iron condor different from an iron butterfly?

An iron condor has two distinct short strikes and a flat maximum-profit interval between them at expiration. An iron butterfly has a shared short strike and a single maximum-profit price.

Can unequal wings have the same maximum loss?

No. With one contract per leg and the same net credit, the wider wing has the larger expiration loss. This calculator reports put-side and call-side losses separately.

Why can the scenario show a loss while price is between the short strikes?

Before expiration, the short options can retain enough time value to make the closing debit exceed the entry credit. Higher implied volatility can increase that debit. The expiry payoff assumes time value has reached zero.

Does this backtest multi-leg options on TradingView?

No. It calculates expiration payoffs and Black-Scholes scenarios. TradingView Options can model multi-leg structures and time or volatility changes, but these scenarios do not establish historical fills or performance.

What quotes and contract sizes does this tool use?

The chain loader uses available daily closing premiums, not executable live fills. All legs must share one expiry and use a standard 100-share contract multiplier. Adjusted contracts, missing inputs, net debits and credits at or above the narrower wing width are rejected by this two-breakeven model.
