I putting this play on, with slightly modified strikes as noted in additions to the post below ... .
The original setup was a 27/37.5 short strangle (Jan 22nd expiration) that I filled for a 1.00 credit. On 12/18, I rolled the call side down from 37.5 to 34 for an additional .26 credit, so I've now got a 27/34 short strangle on.
Covering this for a .51 debit, so I netted 1.00+.26-.51=.75 ($75/contract) on the play. Will look to reestablish this farther out in time or redeploy the buying power elsewhere.
