I have been looking to short NFLX, and after my stint with it failed, I think Tim West's reccomendation makes a lot of sense. He's been holding shorts from considerably higher, and had posted about it in the 'Key Hidden Levels chatroom' recently once again. You can refer to his publications for more information, or ask questions in chat if you have any.
My trade entry is as follows: short at market stop, stop at 103.57, risking 1% of capital on it.
