Complete beginner — what IS trading? I don't even know where to start
I know this is probably the most basic question possible, but I genuinely don't understand what "trading" means beyond "buy low, sell high."
Like, what are all the different types? I see people talking about stocks, options, futures, forex, crypto — are these all different kinds of trading or different markets? Do you need different accounts for each one?
I have about $2,000 saved up and I want to learn. Not trying to get rich quick, just want to understand this world. Where does a complete beginner even start?
