Traps Every Where

Not too happy lately. Busy for sure and careless too. Shorted AMZN at 38 but couldn't hold. Anyway, waiting for rebound to short it again anyway. Biggest mistake at GOOG short. Shorted at after market at 220 level and stop loss at 223 level. The problem is I used too much margin and couldn't hold. The 2nd day pre-market at 226-227 level, but didn't have time to day trade and covered without much gain.

I need to find a way to trade when busy, but this requires proper account management, which is not what I am good at.
