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.
yes that can be right, as long term investment is less risky as compare to long term investment, in short term investment you can lose money in a very very short time if the price start a downward flow you will really come in pressure and will start panic selling and you will book lost.
