With TWTR's IVR at 92 and IV at 103, it's a go for a short strangle. AAPL's IV bumped up a little bit today to 51, but it needs to be a bit higher for me to bite on (70+).
Here's my TWTR setup as of right now:
A Nov 6th 25.5/36.5 Short Strangle
Max Profit: $82/contract
Break Evens: 24.68/37.32
Notes: I'm going a little farther out to be able to manage the trade post in the event I need to roll in order to give it additional time, since I've got a day job and watching the trade post-earnings intraday is problematic. You can naturally go for this Friday's expiry in the event you can easily manage it post-earnings. If at all possible, look to put this on toward the last couple of hours of the NY session, adjusting your strikes to accommodate pre-earnings jitters in the price.
