When One Side Is Tested: Managing an Iron Condor Without Making It Worse

An iron condor is a price on a range: a short put spread below the market and a short call spread above it, sold together for one credit. On the day you open it, both sides look comfortable. The trouble starts weeks later, when the index drifts toward one short strike and the position shows a loss that is growing faster than the credit ever could. That moment, when one side is tested, is where most condor results are decided. The adjustments on offer all sound like repairs. Some are. Others quietly make the position larger, narrower or longer without anyone deciding that on purpose.

The rules first

Decide the trigger before the trade. Write down what counts as "tested": the index touching a level, the short strike's delta reaching a set number, or the tested spread trading at a multiple of its credit. Pick one, and act on it when it happens.
Judge every adjustment as a new trade. Ask: if I had no position, would I open this one now, at this price? If the answer is no, the adjustment is a way of avoiding a loss, not managing risk.
Know the maximum loss after the change. Every adjustment changes the width, the credit, the strikes or the expiration. Recompute the worst case on paper before sending the order.
Credit collected later does not cancel a loss taken now. A roll that brings in new premium does not undo the debit paid to close the tested spread. Keep the two numbers separate.
Closing is always an adjustment. Taking the loss at the planned trigger is a legitimate choice, and often the one that keeps the next trade possible.

Why the tested side matters more than the other

With both spreads on the same expiration, only one side can finish in the money, so the condor's maximum loss is one wing's width minus the total credit. That is the good news. The bad news is the shape of the loss. As the index approaches a short strike, that spread's value rises quickly, while the far side has already lost most of its value and cannot rise much more. The untested side can only ever give back what is left of its premium. The tested side can take away the full width. Every decision at that point is really a decision about the tested spread.

Worked example: one condor, four choices

Every number here is an illustrative example, not a quote. Index options carry a 100 multiplier.

The trade. With an index at 5,000 and about six weeks to expiration, sell the 4,850/4,825 put spread for 1.70 and the 5,150/5,175 call spread for 1.30. Total credit: 3.00, or $300. Each wing is 25 points wide, so the maximum loss is 25.00 minus 3.00 = 22.00, or $2,200 per condor. Breakevens at expiration are 4,847 and 5,153.

The test. Two weeks later the index has fallen to 4,880. The put spread is now worth 7.50; the call spread is worth 0.20. The condor is worth 7.70 against the 3.00 collected, a loss of 4.70, or $470. Assume that loss is the written trigger. Here are the four usual choices.

1. Close the whole condor. Pay 7.70 to close. The loss is $470, final and known. The account is flat and the next trade starts clean.

2. Close only the tested put spread. Pay 7.50 for a spread sold at 1.70: a realized loss of 5.80, or $580. The call spread stays open, worth 0.20 with 1.30 collected. If it expires worthless, the trade ends at minus 4.50, or $450. The risk has been removed from the side that was moving; what remains is a small, far-away call spread. Note that it still carries its own full structural risk of 25.00 minus 1.30 = 23.70 if the index rallies all the way back through 5,175, unlikely but not impossible.

3. Roll the untested call side down. Buy back the 5,150/5,175 call spread for 0.20 and sell the 5,000/5,025 call spread for 1.60. Total credit is now 3.00 minus 0.20 plus 1.60 = 4.40. The maximum loss on each side falls to 25.00 minus 4.40 = 20.60, or $2,060, and the put-side breakeven moves to 4,845.60. That looks like a repair. But the range has shrunk from 300 points to 150, and the new call-side breakeven is 5,004.40, only about 124 points above where the index now sits. A rebound that would have helped the original trade can now hurt the new one. The put spread is still worth 7.50 and still deep in trouble. This choice adds premium and adds a second way to lose.

4. Roll the tested put spread down and out. Close the 4,850/4,825 put spread for 7.50 and sell a later-month 4,750/4,725 put spread for 2.10. The roll is often described as "a 2.10 credit", but the 7.50 paid to close is a realized loss of 5.80 on the original spread. The new spread is a fresh position with its own maximum loss of 25.00 minus 2.10 = 22.90, or $2,290, and it keeps capital tied up for another cycle. It only makes sense if you would sell that later-month spread on its own merits today.

None of the four is right every time. What matters is that the trader can say, for each one, what the new maximum loss is, how long the risk lasts, and whether the new position is one they would open from scratch.

When each choice tends to make sense

Closing the whole condor fits when the reason for the trade is gone: implied volatility has jumped, a scheduled event now sits inside the expiration, or the move looks like a change in regime rather than noise.
Closing only the tested side fits when the far spread is nearly worthless and holding it costs little attention. It cuts the moving risk without paying to close something that is close to zero.
Rolling the untested side fits only when the trader is content with the narrower range at today's price and would accept either side being tested next. It is the choice most often made for the wrong reason: to make the loss look smaller.
Rolling out in time fits when the later expiration pays a fair price for its risk on its own, and when the account can carry the new maximum loss for another cycle.

Common mistakes

Adjusting without a trigger. Deciding while prices move tends to produce the adjustment that hides the loss rather than the one that controls it.
Counting roll credits as profit. A roll for a net credit can still lock in a loss. Track the realized result of each closed spread separately.
Inverting the condor. Rolling the untested side so far that the short call sits below the short put guarantees a loss of the overlap at expiration. Check the strikes after every roll.
Letting size creep. Adding contracts to the new spread "to make the loss back" turns one adjustment into a larger trade with a larger worst case.
Forgetting the calendar. Rolling out can pull an earnings season, a central bank meeting or a major data release inside the new expiration. Check before rolling.

A short checklist for the tested side

Confirm the written trigger has been hit; if it has not, do nothing.
Write down the current value of each spread and the loss so far.
For each choice, write the new maximum loss, the new breakevens and the new expiration.
Ask whether you would open the resulting position today with no history behind it.
If no choice passes that test, close the condor and take the planned loss.
