- Not Maintaining Trading Discipline
The largest mistake any trader can make is to let emotions control trading decisions. Becoming a successful forex trader means achieving a few big wins while suffering many smaller losses. Experiencing many consecutive losses is difficult to handle emotionally and can test a trader's patience and confidence. Trying to beat the market or giving in to fear and greed can lead to cutting winners short and letting losing trades run out of control.

- Trading Without a Plan
Whether one trades forex or any other asset class, the first step in achieving success is to create and follow a trading plan. "Failing to plan is planning to fail" is an adage that holds true for any type of trading. The successful trader works within a documented plan that includes risk management rules and specifies the expected return on investment (ROI).
