No, I don't consider trading as gambling because gambling depends on luck mostly and trading depends on your skills and experience.Though trading needs a little bit luck but it doesn't not matter much rather gambling is just matters on luck.
That depends from your point of view on this but both are risky and need luck in some point. When you gamble or trade goal is same want to gain income so in some point this is matter of opinio on this someone will say they are same other that is not.
It is true, As per definition of gambling, It is risking money base on chance only, Both trading and casino gambling are both depends on luck and there is no guarantee that you can have profit, For me it is just the same, But trading is just formal that is why other people see it in a good way but if you really study what it's behavior, you will notice that it is just another form of gambling.
