Im thinking its positions rolling over. No one probably wants to run the market over 8000 till thats done. Maybe letting all the short money get in then twist the market higher.
Do what you gotta do. If you cant dedicate the screen time than your gonna get burned trying to scalp/daytrade. I bet you do 100% this year if you don't push swings. Wait for the pattern or setup and get in, Don't forget the s/l .. Good luck
