I think having knowledge of rules or reading principles is not a merchant's problem, but following and applying the principles is that big problem that creates big losers traders. we want to be disciplined with rules to follow them. forex is a good job yes it's a very good advice, before trading, especially with using a real account, it must prepare mentally or psychologically, and enough knowledge about forex trading. should practice the ability to analyze market movements, be able to make clear and detailed plans, and be applicable to trade. best of luck
