There is a striking inability to stay with winners. Most traders are too willing to take small profits and, therefore, miss out on big profits. Many traders have the habit of not cutting losses fast, and getting out of winners too soon. It sounds simple, but it takes discipline to trade correctly. This is hard whether you're losing or winning.
Many traders overtrade their accounts.
Futures traders tend to have no discipline, no plan, and no patience. They overtrade and can't wait for the right opportunity. Instead, they seem compelled to trade every rumor. Lack of risk capital in the market means inadequate capital for diversification and staying power in the market. Some speculators don't have the temperament to accept small losses in a trade, or the patience to let winners ride.
