Can I have a precise and constructive answer on whether trading is really worth spending time on? My brother wants to do this job for a living, and I'm just curious if it's a dignified, worth-spending occupation. I don't know where to ask, I don't understand technical analysis; when he explains it to me I feel it's some sort of gambling strategy.
I've used to read experts' discussions, papers, books and the like, but I find no such stuff on trading. It's a very vague term anyway. Are there really people who just "buy low and sell high", making a living by just doing that? I can't comprehend how can a person seriously make a living by something that looks complete gambling, instead of providing goods, services, work etc.
You cannot have trading as an occupation. It isn't supposed to be an occupation. It is supposed to be a side income source, because it isn't guaranteed to always give you profit and you can make huge losses. However, when done well, it could make you much more money than your job or occupation really gives you. But I do not advise to take it as the main occupation you have.
