The cause of losses in overconfident trading. Traders who trade overconfident can never become successful traders. Over-trading people always work with greed, so even if they make a profit, they can't keep that profit for long. This over-trading comes from overconfident. I become overconfident when I make a lot of profit together. And from that overconfident, I lose that profit again. That's why it's never right to be overconfident in trading.
