Sorry if I was confusing-- I sold the straddle, so I should have just called it a strangle, and I had to edit that previous post a few times to get the 3rd grade math correct. 


Actually I liked your trade even if it didn't work out. The short straddle felt like the right trade yesterday.
You may want to check out participating in the HOSS opening of the SPX options on VIX expiration day. One of the few opportunities for almost free money these days.

Not sure I understand this page. How do you participate in this?
On the morning of VIX expiration, everyone (customers, marketmakers, firms) can participate equally in the following months SPX option opening. The opening prices of these options are used to "set" the VIX settlement price. Indications are listed at the previous page I posted. There are usually very large orders in the SPX that are used to "massage" the VIX print. Not sure if it is large customers simply rolling postions or not. For example today there were large sell orders in the options, thus a lower VIX print.
The opportunity is to essentially be able to buy or sell an option with edge. For example today you could see that there were large amounts of puts and calls offered. One play with the least risk is to buy the out of the money puts for .05 for knowing that yesterday the strike 100 points lower were .05 bid, then sell the options just after the opening for .10 or .15. Other more aggresive plays could be done with meatier options.
OK so you look at the offers before the open then buy / sell based on that? So if there is heavy liquidity on the bid you buy it up then sell after the open? If I got it right? And if there's lot of liquidity on the ask you sell it?
What a print! 15.45 preliminary from last night close of 14.25. FSU, I hope you werent short straddles this time around
