-------------------------------------------------------------------
about $0 flatness
0) Option prices are closed now, so the idea above is about revenue, not about strikes (which are taking the $55 delta).
1) rinse/repeat the theme above.
2) take $5 or so off each time, go out in time if needed, working the ITM puts ever down.
3) NEVER forget that you've now got $10 (or whatever comes later) in new risk on the top side.
4) NEVER "cross the streams" by having short calls go below short puts, which would leave you *highly*screwed*, should NFLX approach between those two prices.
(For example, short call at $360, short put at $365, and NFLX goes to $363, and you're ITM on both.

)
Be patient. You've really screwed the pooch on this one. Take your time to get out.
