In 2011, I was shorting the market and it kept on going up. I should have put a % Stop Loss on that trade or at least a Time Stop Loss but I did not.
Instead, I kept on hoping that the market direction would change but it did not.
In 2012, I made the same mistake again. This time, I was long the market and it kept on dropping. However, I did have a Time Stop Loss this time and cut it after 3 weeks.
After I have cut my position, it went up and had I stayed with that position, I would have recovered back my losses.

Lessons Learnt:-
1. I'm not really that good at predicting Market Direction
2. Percentage Stop Loss is better than Time Stop Loss
3. Never carry forward a loss over a week-end, if you are trading short term
