Chance of any profitCalculated by a model

71.2%

Assumes a lognormal terminal price (geometric brownian motion), the same distribution black-scholes assumes with volatility of 30.0% and risk-neutral drift. Real returns have fatter tails than this model assumes, and volatility itself changes. Other tools quote different numbers mainly because they assume a different volatility or a different expected drift.

Greeks

How the position responds to price, time, volatility and rates, for the whole position rather than a single contract.

delta

share equivalents
How many shares this position behaves like. A delta of 50 gains roughly $50 for every $1 the stock rises.
gamma
−2.0407
delta per $1 move
How quickly delta changes. High gamma means the position gets directional fast as the stock moves.
theta

dollars per day
What time decay costs or earns each calendar day, if nothing else changes.
vega
−7.55
dollars per 1% of volatility
What a one percentage point change in implied volatility is worth to this position.
rho

dollars per 1% of rates
What a one percentage point change in interest rates is worth. Usually the smallest of the five.

Every column before expiration is a model estimate that assumes implied volatility stays where it is today. Only the expiration column is arithmetic rather than a forecast.

Notes on the iron condor

  • Maximum profit is the credit received, earned between the two short strikes.
  • If the wings are different widths, the two sides risk different amounts.

How an iron condor works

Four legs: a put spread below the stock and a call spread above it. You collect a credit and keep it in full if the stock finishes between the two short strikes. Both sides are capped by the long wings.

When traders use it

When you expect the stock to stay inside a range through expiration.
