I had a position on already when I posted. Here's the whole story with lessons learned for any interested:
On Oct 14, I sold the Nov 54 call (20 delta), 46 put (21 delta) (strangle) for $1.15. Stock price around $50
On Oct 28, IV had increased a bit and stock had only slightly moved up to around $51.50. So my options were still safe but I had the opportunity to take some risk off. I rolled out to the Dec 55 call (23 delta), 45 put (17 delta). I paid -$1.22 to close Nov and received $1.29 for Dec. Total basis is now $1.15 - $1.22 + $1.29 = $1.22 but with wider strikes. I liked the trade and the IV so I also added more contracts; in hindsight I should have just managed this trade and traded a new strategy alongside this one (still in EWW if I wanted) to diversify and reduce risk.
On Nov 10 there was a massive crash in EWW. Stock went from $53 to $44 in 2 days with the election results. Obviously this was testing my short put, but my call was now worthless, so I rolled it down to the Dec 45 call (turned the strangle into a straddle by rolling down the untested side). I paid $-0.06 for the roll and received $1.50 for the new one. Total basis now $2.72 but I have the Dec 45 straddle instead of a strangle.
To be honest, on Nov 9 I could have closed my straddle for around $-0.76 for a total profit of $0.46. However, I was hoping for a larger profit but in hindsight I should have just taken off the risk when I had the chance.
At this point I'm just looking for a scratch. Another mistake was my account was in the middle of being transferred as well, so I couldn't close even when the stock rallied back briefly. However, enough time passed and there was a slight rally (up to $44), so I ended up closing the trade on 11/28 for -$2.04. So overall I still made $0.68 on the whole trade, without having to make any directional assumptions (i.e. predict the election). When I opened the trade I was only shooting for 50% profit ($0.58) so I'm pretty happy with this result even though I made several mistakes.
I learned how to manage this trade and got the ideas all from watching TastyTrade since July 2016.
There's no IV out there these days, so not doing too many strangles right now. Have a calendar on in SPX and been doing debit spreads in other low IV products. I think the only strangle I have on is NVDA which is bouncing around lately.
