Most traders do not make money in trading over the long-run for one simple reason: they trade way too much. One curious fact of trading is that most traders do very well on demo accounts, but then when they start trading real money they do horribly. The reason for this is that in demo trading there is virtually no emotion involved since your real money is not on the line. So, this goes to show that emotion is the number one destroyer of trading success. Traders who over-trade are operating purely on emotion.
Furthermore, another common mistake is not applying risk reward and money management correctly, since risk management is critical to achieving success in the markets. Risk management involves controlling your risk per trade to a level that is tolerable for you. Most traders ignore the fact that they could lose on any trade, if you know and accept that you could lose on any trade. Since, why would you ever risk more than you were comfortable with losing?
