I say flat for today but just taking a random guess
After the big decline days you tend to get what I call a consolidation day with choppy trade that goes nowhere digesting things before the decline resumes in the coming days
Saw that in the recent dive when it really started to pick up steam...it alternated between big down day and consolidation day before it found it's near term bottom
I wouldn't mess with this market day trading you will most likely get chewed alive by the robots.... Stick to making trades you plan to be in for at least a week
