according to my trading experience i think there is anyone can be a trader in trading demo or real . this is not a big deal , but the main deal how to survive successfully in there with great level of patience.
right now Forex is really a professional business in the present world but almost 90% traders become loser from this trading place due to low trading knowledge and experience.
i have seen sometimes after having most powerful risk management , the result of trading be useless , because market is so much volatile and there is no one can predict it with certainly.
