Every trader is different, and only you know your risk tolerance. Are you the type of trader who can risk 20% to make 20%, or do you feel the need to have a much higher risk/reward payout in order to enter a trade? Be sure to define your risk before placing any trade orders. Doing so helps ensure that you have an exit strategy, which is arguably just as important as your entrance strategy. A little extra work in the beginning can make all the difference in the end.
