Many brokers do charge high fees and commissions which is the reason why forex traders most time will not want to end there trades because of the commission they will pay including the fee if they end the trade at early stage. They would want to trade more or wait for the market so that they can get a preferred level when the market will go bullish and appreciat more and at the end they might incurred loses which might have been avoided if they left the trade at an early stage. We all trade for profits and I don't always know when loses will appear.
