Don't buy any courses. That is probably the worst thing a new trader can do, because 1) 90% of "courses" are garbage written by wannabe traders who are good at marketing (and not trading), and 2) the "courses" usually direct you to a certain method of trading, and that might not even be what you want. If you are set on paying someone money, go to Trading Schools.Org - Live Trading Rooms, Trading Software, Trading Mentors, Brokers ( first and check out your supposed expert. 95% of the experts are anything but...
So, I always recommend to read lots of trading books. Read anything you can find. Don't judge the content - just absorb it.
After a while, you'll start to separate real information from fluff, and you'll start to see what kind of trading might appeal to you. Then, start to heavily research the approach to trading that seems to fit you. Pursue that.
While you are doing the reading and research, try to get as much risk capital together as you can. You will not make it with a $5K account. Aim to start with $25K, $50K or even more. Risk of ruin is directly related to starting account size. Undercapitalized traders get killed.
At some point you'll want to start trading, and possibly seek out expert advice. Just don't do it right off the start.
Take it slow.
