Well, in essence, it seems okay, but that is a pretty high margin requirement ($40,000) to just make that small amount of money, although the range is pretty wide enough (although you never know).
Glad to pass it on. It is called OptionsOracle and is a freeware program from SamoaSky.
Although it doesn't have the backtesting tools that OptionVue has (I wouldn't use it anyway), it is equal to the performance with saving the $1,000+ price tag of OptionVue.
(Also note: The example I gave has Interactive Broker commissions imbedded in, which is why you might get a difference decimal difference than what you came up with.)
Jan vol will drop 300 to 500 bp. You're modeling flat vols. You are long vega, a lot of vega. My guess is that the position will be marked to a loss when it begins trading after the report.
Short gamma, long vega. I realize it's tempting to sell the duration-skew, but it's likely a better entry after the report.
