We're already to 3750 area on futures, I assume they will attempt to hit 3770-3800 today. I don't think it goes much higher than that although the green path is there just in case. I expect a fall from these levels to 3500 in the coming weeks - yellow path. This lines up with what I see on AAPL and other stocks. The short idea is invalid if they can start getting over 3820 on a daily close. Good luck!
