Some say 90 % of the open interest will expire worthless. Whether it is 10% or 90%, it has been debated in another thread. Today we are interested to see which strikes you think will expire worthless, and how did you come to that calculation.

I use the ODDS probability cone in Metastock, set to two standard deviations of 20 day volatility. What do you use?

I don't see the point either, but what the heck... SPX - below 1485 & above 1580 NDX - below 1950 & above 2125 RUT - below 790 & above 880 As to how I got these...sorry, it's a proprietary calculation.

my take: NDX closed yestereday at 2036 I use a 10% projection, my condor strikes will be: 2265 2240 1850 1825

mte... if i had your proprietary calculator; i would be all set. if you have a change of heart, keep me in mind

I'm gonna go out on a limb here. SPX 1150 puts will expire worthless as will NDX 1350 puts Oh what the heck... while I'm at it, I will also say that SPX 1725 calls will expire worthless too.

Better watch the RUT 790s. Only 20 Points OTM here. RUT breaks 800 (not likely but high vol usually leads to higher vol) theres a free fall every 20 points.
