I was trading pretty well until I set a monetary goal for myself. I say, just $100/day. Then all a sudden, I was making $200/day, $500, and then $1000/day. I ran my $10k to almost $20k in less than a month.
Guess what, I was been greedy and STUPID. I just ignore my rules, and start chasing on the amount instead of trading well. I gave all the gain. Now I am just sitting on sideline until I get over it and mentally prepare again.
