Any amount you have you can go into trading right away. But always learn to trade with only the amount you can afford to lose. That will help you minimise loss
if we still beginner better use small amount that we accept to loss.so when we did the mistakes and make our money gone, we would not panic and blamed the market.
as beginner we need to preapared our self with trading skill.never join in this market if we didnt have any trading skill.and trading just following other people advice.
