Quote from Div_Arb:
Looks like you are going to immediately loose money tomorrow, since QQQQ is trading up over 1.5% in after hours. This is due to the positive earnings report by GOOG. Obviously, since you are a beginning trader, you did not take this into account.
Part of becoming a successful trader is not what you do, it's what you don't do. If I were you, and my models said "short" one day ahead of GOOG earnings, i probably would have held off a day or two to see how the market responded.
You live you learn, and learning to trade is very expensive. Unfortunately, there is no way around this.
It seems that me inexperience has cost me on my first trade. But I'm in this for the long run. I truly appreciate you guys taking time the read this and giving me some useful feedback!
