Trading is not for regular profit. It is very risky it will not always give you profit. You are only a boy of 19 years, If you trade at this age, and to incur losses, it will greatly affect you financially problem. So I think you should stay away from trading until you start earning enough money. Because anytime it puts you in big losses, you won't be able to cover those losses very easily if you don't have any other source of income. So make yourself a permanent money making place, then start trading.
