Iron Condor Entry Screening: What the Rules Check First

Why does entry screening matter more for condors than other spreads?

A directional spread has two ways to work: the move happens, or premium decays. A condor only has the second. The CBOE's own condor benchmark index is the honest expectation-setter here: it compounded roughly 10% a year from 1988 to 2010 and then roughly zero from 2010 to 2019. Flat stretches lasting years are normal for the structure. The regime-dependent part, whether the volatility being sold is actually rich, is what separates the paid decade from the flat one, which is why a volatility-premium gate rather than the structure itself is treated as the source of the trade.

What gates does a condor candidate pass in Options Scanner?

• Volatility premium: NVRP at or above the configured floor, so the implied volatility being sold is at least as high as the stock's realized movement. Notably, IV rank does not gate entries, because rank reads highest right after volatility spikes, precisely when the real premium is already thin.
• Liquidity, judged on the weakest wing: minimum open interest and daily volume on the short strikes, and a bid-ask width ceiling relative to mid. A condor is judged by the worse of its two wings, since exiting requires trading both.
• Event screens: no expiration spanning the stock's earnings date, and a macro calendar check for events like Fed decisions and CPI releases near entry.
• Compensation floor: total credit at or above a configured fraction of the wing width, so the position is paid enough relative to its worst case.
• Placement vs the tape: short strikes outside the recent trading range, measured in expected-move units for that expiry, so the safety margin scales with how fast the stock actually moves.

A candidate failing any single gate is logged with the exact gate that failed and the number it failed by, rather than silently skipped.

What does the worst case look like?

Max loss is exact at entry: the wider wing's width minus the total credit collected, reached only if the stock closes beyond one wing's long strike at expiration. Position sizing off that worst-case number, rather than off the credit, is what keeps a string of losing condors an ordinary drawdown instead of an account event.

Frequently asked questions

What conditions do iron condor entry rules commonly screen for?

Typical rule sets look for elevated volatility pricing, a range-bound or neutral trend reading, no earnings event inside the trade window, adequate option liquidity in all four legs, and short strikes placed inside a chosen delta band. Each element is a filter with a measurable value, which is what makes the checklist automatable.

Why do condor rules avoid earnings inside the trade window?

An earnings date injects a known jump risk that the day-to-day volatility statistics do not describe. The implied move around the event reprices the whole chain, and a single gap can traverse both wings. Screening the calendar out of the trade window removes the one scheduled event most likely to produce the structure's worst case.

Why is an options volume floor part of condor screening?

Wide or empty markets in any of the four legs raise the cost of both entry and exit, and the exit matters more: a position that has to be closed defensively in an illiquid chain gives part of its edge back to the bid-ask spread. Volume floors are also most meaningful when they account for how options volume builds over the trading session.
