no i do not consider trading as gambling although both are risky but still trading is a little safe than gambling, in gambling you never a chance to return your money back.
As long as you go for longer term trading then it is more safer than gambling but if you want to make a quick bucks from trading like day trading then it is almost equal to gambling. So if you want to earn money from trading then don't ever go for day trading.
day trading are not gamble at all ,
you just speculate it , make a quick money through a short time period in a day doesn't mean it is a gamble ,
trading is trading and gambling is gambling this is two different things ,
people compare both only on how people make a prediction about certain price.
