This is for NQ. How long until you were pretty sure of the day's trend? For me, its D !! 
TRICKY DAYS!!
At the start of the day, I thought this was definitely an up trending day. The easiest part was by far the end of the day
Quick summary: Bought A and B, sold C.
Short D. Covered at end of day. It was tough to wait at that consolidation after D - it could have gone either way. After the breakout, it was clear how the day was going to end.
I also traded ES in parallel. That didn't go as smoothly. Basically I bought up on the spike after B and sold on the bottom at C (but sold more than I bought to enter a short position) just like the NQ. That obviously didn't work judging by the spike that followed. I exited near the peak of the spike by going long again, but too late. Ended up selling after a small dip from the peak. Took quite a bit of loss.
I'm starting to realize reversing position on the same trade isn't really something that works so well for me.
All in all, I netted positive a few hundred bucks - but tough stuff. These mid-day reversals are almost expected, but the swings are so large its hard to tell which is which.
