If you're a mentally strong person with experiences in trading, then your mental control is stronger than a newbie and that could help you maintain your trades and you're less likely to sell out of fear or enter cause of greed. I guess your psych has a lot to do with your success or failure too. I try to maintain my calmness and only open trades that I strongly feel will reap me profit and I have been profitable so far. I do not get in gambler's mood at all. How about you? How good are you at staying cool and calm?
