Stay focused on the goal. Exit your trade immediately if your position is not acting according to your expectations when you entered the trade. Stay in winning trades so long as you remain in profit, but do not give too much profit back. If you are day trading, once you are profitable by 10 pips, you should exit a winner, with at least 2 pips. Once you are profitable by 5 pips, you should exit at least break even. As soon as your position nears zero, get out. Do not exit your position unless you are at immediate risk of losing your profits, which you should always keep.
