May 19,2017: pre-opening
Tracking of account alpha for this week: 5.18.2017: 0.3 5.17.2017: -0.9 5.16.2017: 0.53. May 17th is the worst performance day, lagging the SP500 by close to a point, here are the reasons, the stocks that flying high during regular season will be dumped even worse, that is FANG, that is IBD50, therefore register the worst day of my day trading history. Lesson learned, if the overall market is heading downward sharply, you should be able to dump the worst performance stock even it loses to minimize the overall. Capital is the king! Should be a good day for today, let's try to scale back a little bit, should have cash position around 15% by the end of the day, in addition, should limit the trading to certain degree, let's target maximum 10 trades for today.
