Here's a basic setup:
NDX/IUXX Mar 11th 4190/4200/4420/4430 Iron Condor
Probability of Profit: 63%
Max Profit: $335/contract
Buying Power Effect: $665/contract
Notes: Like RUT or SPX plays, this is one that you want to fiddle with getting a fill above the mid price, since price can swing back and forth across that by +/- .20 given the wide bid/ask due to the price of the underlying. Hey $20 is $20 and if you're going 2 or 3 contracts or more, that little .20 swing can add up and be significant. I generally set price .10-.20 above the mid, see if it gets filled, wait a bit, adjust price slightly, etc.
As with all iron condor setups, I look to take the play off as an entire unit if I can for 50% max profit or, if a single side is approaching worthless (.10 or less), I look to take that off first. In the event a side is breached, look to roll it out another week, improving strikes if possible, and selling an oppositional side against for at least a credit that exceeds the cost/debit to roll any tested side.
