Reminder : Forex is a zero-sum-game which is made negative-sum because of the "small" monthly charge and fees you have to pay to play it.
Exception for going out doors on the street and buying from one market and selling into another which our "Currency Exchange Dealers" on the street do. Then you are serving the people. Instead sit on a laptop and buy and sell, you will lose money *slowly*, no matter how "expert" a player you are. And then the arrangers will blame your in-expertise for your loss.
