You need to be disciplined enough to only trade the most obvious trade setup each week, and this might mean you don’t trade at all some weeks. You must understand that we are leveraging the power of risk reward combined with a mastery of your trading strategy to make money, but since we never know which trades will win and which trades will lose, we have to have discipline to remain calm and follow our plan even in the face of inevitable strings of losing trades. The best way to do this is to create a Forex trading plan around the one trade a week strategy, this will give you a tangible reminder of what you overall approach is for trading the markets and will work to continually reinforce what you need to do to reach your trading goals.
