Rule #3: Stick With It. This rule seems like a no-brainer, but you'd be surprised how many day traders experience a bit of success and cast their forex day trading systems aside. The whole point of choosing an effective day trading system is to make money, and ignoring your trading strategy is guaranteeing loss. A bad day forex trading doesn't mean you've chosen a losing forex day trading strategy; it just means that you had a bad trading day. Give your strategy time to work, and understand you will have winning days and losing days. By sticking with a forex day trading system, you can make sure you have more good days than bad.
