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.
Yes trading can be profitable as long as you are good at it or being lucky many times. If you are unexperienced and think it's an easy way to get rich, the chances are very high you are going to lose money. Since you have no background in reading I will try to simplify things a bit. Think of traders in the market as a zero sum game, for one person to make money someone has to lose money. So on average you would have 50% of the traders making money, and 50% losing money. It's a bit more complex than that because there are fees and transactions cost to consider. As a very good trader you can make a lot of money. How much experience has your brother in trading? If he did it a few years successfully he might be able to do it for a living, but without any experience I think it will be hard to cover all his living cost. Also does your brother has a decent bankroll to start with? Starting from zero can take some time to build up an portfolio.
