One can earn in a forex market. Its open 24 hours a day adn weekdays are good days to trade as the weekend the market is closed. Business hours are good hours to trade. For me, Tokyo time is the best for me. It has worked for me almost every single time Monday morning 11am Tokyo time. I think timing is everything since demands is high in certain hours crating a lot of opp for scalper. Now, as a newbie, you must learn all that you can regard forex and practice in a demo as much as you can until you can take profit then open a cent account to practice in real money market to see if you can handle it.
