as far as i am concerned, trading is not gambling . It is true that the risks and the possibilities of winning are similar, that you might get rich if everything goes okay as you can in one second lose everything , but trading is a job , it doesnt depend on just luck and you have to work hard for it. the difference between trading and gambling is both the amount of effort and investment put into trading.
Risk and possibilities on trading and gambling isnt really similar at all but they are both ways on earning money but the risk level factor isnt really the same.Trading would only be just considered as gambling if you dont have knowledge on doing it and yes gambling would really rely on luck which on trading it doesnt since skills would really matter on this one.
