As with any business, being successful requires a plan. Forex trading is no different in this respect. To trade profitably requires planning and then reviewing, possibly revising, and definitely following that plan.
Plan to be successful by making sure that you do your homework. I've seen people jump into Forex trading after studying the trading business for the same amount of time it takes to read a lunch menu. This is a big mistake. The Forex market eats unprepared traders alive.
