After being exercised in some of my $RSX September Puts, I decided to do a little bit of a different trade. Buy back your 21Sep puts in RSX, then sell 100 19Oct $20 strike, and buy 50 19Oct $18 strike puts.
If you put this one on, you may need some help to prevent any kind of margin errors. Please direct message me on Twitter. This is due to a thesis change.
