I did a stimulated Siamese Condor (via ThinkorSwim). Last November, bought a SPY Siamese Condor for a credit of 5.33 with a range of 18 points. Today, sold the SPY Siamese Condor for a debit of 3.97. The SPY finished near the middle of the Siamese Condor. Roughly, that translates to a 25.52% profit. What's a Siamese Condor? It's the same as the Iron Condor, except the short call and short put are at the same strike price. By doing this, you maximize the premium credit for the same risk as the Iron Condor. Here's an article on Siamese Condors: http://www.sfomag.com/homefeaturedetail.asp?ID=1563109335&MonthNameID=September&YearID=2004 I think if I were to open a Siamese Condor, with a range of 18-20 points and 3 weeks to expiration, I would have a 80% of a successful trade.
