Given the value of the underlying and its accompanying options, having more "meat on the bone" allows you to go wider with your iron condor, increase the probability of profit of the setup, and still get something for your trouble (the only way you can do that with IWM is to increase the number of contracts involved). While I ordinarily place the short put side of my index , SPX , or RUT iron condor setups at one standard deviation out (84% probability OTM), here I've gone somewhat out to the 94% probability OTM strike for the short put; on the call side, I ordinarily set up the short call at the 75% probability OTM short call, but here I've gone out to the 80% strike.
Here's the setup:
RUT/IUX March 31st 805/815/1060/1070 Iron Condor
Probability of Profit %: 73%
Max Profit: $210/contract
Buying Power Effect: $790/contract
Notes: Look to take the entire setup off at 50% max profit and/or balance the setup's fairly delta neutral disposition by rolling sides in toward current price if you've still got 25 days or more until expiration ... .
I put something like this on last week while waiting for my Feb SPY IC's to finish out, but neglected to post it here ... .
