Adjusting a Condor's Flight Plan

Options expert Russ Allen of Online Trading Academy details the steps to take when a stock moves away from your profitability range.
Below is the price chart as it stood for Yahoo at the time we put the trade on:
Here’s how I read the situation at that time:
The stock of Yahoo (YHOO) stood at $37.73, roughly midway between major support at around $32 and major resistance at the recent highs around $42. Implied volatility at 35% was on the high side compared to readings over the last year.
We could have bet that YHOO would stay in the $32-$42 range for the next month, based on the supply (resistance) and demand (support) levels shown on the chart. Bolstering our opinion was the fact that, based on the 35% volatility reading at the time, our probability calculator showed a 79% chance of YHOO staying within that $32-$42 range.
We could have put on an iron condor using the 30 and 32 April puts, and the 42 and 44 April calls, for a net credit of $.35 per share. This $.35 would be ours to keep if YHOO stayed within the 32-42 range. Since each of the two spreads that made up the condor (30-32 puts and 42-44 calls) was $2.00 wide, the most we could possibly have to pay to extract ourselves from this spread was $2.00 per share. Subtracting our original credit of $.35 from this $2.00 maximum exit cost gave $1.65 as our maximum loss.
Here is the option payoff diagram for that position as it stood on March 14:
The yellow vertical line was the March 14 stock price ($37.73). The gold and dark green lines were placed at one standard deviation away from the current price, at $34.25 and $41.21. The red and blue lines were at the trade’s breakeven prices of $31.65 and $42.35. With our breakeven prices farther away than one standard deviation, it was statistically unlikely that YHOO would reach those levels in the time remaining.
Two weeks later, YHOO’s chart looked like this:
The stock had moved around a bit, but well within our profitability range. It was almost exactly midway between our 32 and 42 short strikes. The value of the condor had dropped from our original value of $.35 down to $.13, meaning we had already accrued $.22 worth of profit (i.e. we could have unwound the iron condor, buying back all the short options, and selling all the long ones, for $.13, which was $.22 less than the $.35 net credit we originally received).
There was no need to take any action at this time, as the value of our position was deflating nicely, and right on schedule. Assuming that YHOO didn’t move out of the 32-42 range, all we would have to do was wait for all the options to expire.
But what if YHOO did show signs of moving beyond our profitable range? Is there anything we could do to improve the situation, if needed?
Yes, there was. But before I describe that, I want to answer a question that I received from a reader about this trade:
“…with a $.35 net credit and maximum loss of $2.00 does this mean I could lose $2.00 X 100 = $200, but only make at most 100 X $.35 = $35?
I normally try for a profit two to three times greater than my risk, so this is confusing.
First of all, it is true that the maximum cost to exit this trade is $200. That is not the maximum loss however—we have to subtract our $35 credit, making the maximum loss $165.

A good rule of thumb is in fact to try for a reward-to-risk ratio of 2 or 3 to 1. Here we appear to have a reward-to-risk ratio of 35/165, or about 1 to 5. There are a couple of reasons that this trade is not as upside down as it might seem at first glance.
First of all, this position (and any position) should have stops placed so that we don’t incur the maximum loss. We have no intention of sitting by while YHOO moves out beyond either of our maximum loss points (30 or 44). Our stops would take us out of the trade if YHOO dropped below our $31.70 demand level, or rallied above our $41.72 supply level. For that reason, we would use our stop prices in figuring out the risk for our risk/reward calculation.
At those stop prices, should they have occurred right after we put the trade on, our loss would have been about $70. And the longer it took to reach those stop levels, the smaller our loss would be, as the entire position accrued profit day by day due to time decay. As of March 28, our losses at those levels would have been about $45.
Still, even using our stop prices to estimate our loss, we stood to make less than we stood to lose. How can that make sense?
The answer is probability. The chance of YHOO moving far enough to stop us from making a profit was low. Our probability calculator (standard equipment in TradeStation and other platforms) had showed an estimated 79% chance that YHOO would remain within our maximum profit range of $32-$42, and an 82% chance that it would stay in the breakeven range of $31.65 to $42.35, all until the April expiration.
We could make an extremely rough estimate at expectancy based on these numbers. Expectancy is the average amount of profit we would expect to make on this trade, if it was repeated many times. In this case, we could calculate this as follows:
79% chance of maximum profit of $35: .79 x 35 = $27.65
18% chance of being stopped out for a $70 loss: .18 x -70 = -$5.60
3% chance of an intermediate result.
This could be anywhere between +35 and -70: .03 x (+35-70)/2 = - $ .52
Net expectancy: $21.38
Note that this is an oversimplification of the real expectancy calculation, which requires using some calculus to integrate the full range of expected values. But it should be close enough to illustrate the point: if the chances of success are very high, then the reward-to-risk ratio can be lower.
Finally, how could we protect ourselves, if YHOO strayed out of its profitability range, other than just shutting down the trade at our stops?
We could roll the spread on the losing side. For example, if YHOO hit $32, we could fall back to the next demand level around $28. This means we would buy back the 30-32 put spread portion of the iron condor, and replace it with a 26-28 put spread. At that point, the new spread would bring in a significant portion of the amount we would have to pay to buy back the old one. Meanwhile, the short options on the winning side (the call spread) may have dropped in value to just a few cents, so that we could buy back the short calls too (no point in selling the long calls, since they would probably be worthless, being now so far out of the money).
In this example, we looked at a good strategy for range-bound situations with high implied volatility; and explained why with certain positions, what looks like a poor reward/risk ratio really isn’t. We also discussed means of salvaging an iron condor position when it goes against us.
