Iron condors: get paid on both sides of the range.

The range-bound doctrine

An iron condor sells a put credit spread below the market and a call credit spread above it, collecting both credits. The position keeps everything if the underlying finishes between the two short strikes at expiration. It is the purest expression of a non-directional thesis: not “the market will go up” or “down,” but “the market will move less than the options are currently pricing.”

That last phrasing matters. The condor's real opponent is not direction but realized movement versus implied movement. When implied volatility overstates what the underlying subsequently does — which is the historical tendency, on average — the range implied by the short strikes is wider than the range the market actually uses, and the condor collects the difference. When a quiet market abruptly trends, the condor pays for it. The doctrine is therefore: trade condors where ranges are the norm (broad indexes, large diversified names), not on single stocks prone to gapping.

Capital efficiency is the structural bonus: because the underlying can only finish on one side, brokers margin the two wings as a single risk, so the second credit is collected without a second block of buying power.

IV conditions: rank ≥ 50, stable regime

Condors are short volatility twice over, so the volatility environment is the first gate. The working rule: IV rank of at least 50, so that the credits being collected are in the upper half of the underlying's own one-year range. Rich IV does two things for the condor — it fattens the credits, and it pushes the same-delta short strikes further from the money, widening the profit zone for free.

The second condition is regime stability, and it is the one traders skip. High IV that is high because volatility is actively exploding — a market in freefall, a macro shock in progress — is not a premium-selling opportunity; it is a trend in progress wearing attractive credits. The favorable setup is elevated-but- stabilizing IV: the spike has crested, the underlying is carving out a range, and the options market is still charging panic prices for movement that is already decaying. Elevated and falling IV, not elevated and rising.

Strike selection: short strikes at 0.15–0.20 delta

The standard construction places both short strikes at roughly 0.15–0.20 delta — each side individually carrying about an 80–85% chance of expiring out of the money. Symmetry in delta (not in distance) is the point: puts trade at higher IV than equidistant calls because of skew, so a delta-balanced condor is wider below the market than above it. That asymmetry is correct, not a mistake to fix.

Wing width is the second decision. Narrow wings (5 points on an index) cap risk tightly but spend a larger fraction of the credit on protection; wide wings collect more net credit per contract but concentrate more risk in fewer contracts. The usual entry window is 30–45 DTE, the same theta-versus-gamma compromise as any short-premium trade.

The math: a worked index example

QQQ trades at 480 with IV rank 62. You open a 30-DTE iron condor: sell the 450 put and buy the 440 put (collecting $1.10), sell the 505 call and buy the 515 call (collecting $0.90). Total credit $2.00 against 10-point wings:

The shape of the trade is explicit: risk $800 to make $200, in exchange for a wide zone in which the full profit lands. Note that only one wing can lose — the $800 max loss is the worst case on either side, not both. As always, the max loss is the sizing input: at a 2% cap on a $50,000 account ($1,000 budget), this is a one-condor position.

Adjustments: roll the tested side, close at 50%, exit at 2x

Take the whole condor off at 50% of the total credit — in the example above, buy it back around $1.00. The remaining profit is small relative to the gamma risk of holding two short strikes into the final weeks, and recycling into a fresh 45-DTE condor restarts the theta clock at a better rate.

When one side is tested — the underlying approaching a short strike — the classic defense is to roll the untested side toward the market, collecting additional credit that widens the breakeven on the threatened side. If the move continues, roll the tested side out in time, but only for a net credit; paying a debit to postpone a loss is the adjustment that turns one bad trade into two.

And keep a hard exit: when the total loss reaches about 2× the credit collected (a $4.00 debit to close the $2.00 condor above), take the trade off. Adjustment is for defending a thesis that is still plausible, not for refusing to be wrong. A breached condor near max loss has almost no remaining leverage to adjust with — the time to act is while the short strike is threatened, not after it is through.

Earnings condors: a caution

Selling a condor over an earnings report looks irresistible on paper: IV is at its annual highs, credits are fat, and IV crush after the announcement hands the position an instant profit — if the stock stays inside the strikes. The problem is the “if.” Earnings moves are fat-tailed; the stock jumps to its post-announcement price in a single print, and no management rule executes through a gap. The 2× stop, the tested-side roll — none of it exists between the close and the open.

When the realized move exceeds the implied move, the condor loses at or near max loss immediately, and one such event can return many months of collected earnings credits. If you trade them at all, treat them as their own strategy: wings wide enough that max loss is genuinely acceptable, size assuming the loss side hits, and the expectation that profitability shows up only across many occurrences — never in any single name's report.
