This strike has HUGE Open interest and volume. One could also consider the $90 Jan 22nd put sale I have no qualms regarding BTC this put sale in 3-4 days or a week if FB trades sideways or bounces and I capture 70% or more of the prem. Nice bearish gap on FB today, not going to deny that. However, it is a bearish retest gap and the 100 SMA should provide some support and I don't min d owning shares of FB anyway, if it happens.
