Understand the changing delta, gamma, theta and vega of an iron condor as price approaches either short strike.
At entry
A balanced condor around the current price may have modest net delta. Time decay can help if the underlying remains within the range, and defined wings cap expiration losses.
Approaching a side
A move toward the call spread makes the condor increasingly negative delta; a move toward the put spread makes it increasingly positive delta. Negative gamma accelerates this adverse change.
Volatility and time
An IV rise often hurts through negative vega, while theta may help. Near expiration, the position can show attractive decay but sharp gamma around a short strike, requiring careful sizing and exit planning.
A practical example
A condor starts near zero delta. After a rally toward the short call, it becomes negative delta and loses from negative gamma; if IV also rises, negative vega can add pressure.
This simplified example isolates selected sensitivities so their interaction is easier to understand. Live option prices also reflect the underlying price, time decay, rates, dividends, liquidity and transaction costs. Greeks are theoretical estimates, not guarantees.
Frequently asked questions

It may start near neutral but becomes directional as price moves.
Does positive theta mean daily profit?
