Duy, you need to get on the reddit board. Some guy there is very good at what he is doing. He called the S&P bottom today at 1404, it hit 1401.80, so he was very close. He has other good calls in the past so I dont discount his advice.
Yea that had me fooled but when I looked at the RSI on the S&P I saw it was poised to pop. Anyhow, I sold the FB puts for a 5 dollar per contract profit. Basically break even after trading fees. But I live to fight another day.
