guess,but i thinks its bots and etf traders gettting flat on imbalance at end of dayQuote from gmst:
I don't know but let me guess about it. Someone is either testing a new algo in the hft space and its going wrong in its risk management so its selling incredibly fast at 4pm. Remember infineon CL algo gone bonkers.
Other than that the price action says that it has to do with some kind of imbalance. Could be anything - stock/index imbalance, imbalance in an options book, basically some kind of fcuked up risk imbalance.
Final guess - it is some kind of manipulation again by some algo. Could be some discretionary trader as well.

If I had taken profit at +2 points for every trade I was in today, I'd have +4 to +6 points on the day.. instead, down about -4 points, I keep getting chopped up. This non-directional bullshit is difficult.

This is the rally I was looking for and shaken out of. That's 3 times today I was stopped out 1-2 ticks before a substantial move in my direction. This is a game of precision and I blew it big time today trying to be too creative.
