You've already made the decision to begin your career in forex day trading, but how do you go about choosing which forex day trading system to use? The good news is that choosing a strategy is the most difficult decision you have to make; the bad news is that only you can make this decision. Because you will always open and close your trades within the same 24-hour period, you must choose a forex day trading system that relies on short-term indicators. As a day trader, you should only look for forex day trading systems that accommodate your needs.
