Just go for it. Though you should really set your standards low when you're just starting out; expect to lose same trades left and right. You fail as you learn though so yeah, your goal should be learning at first.
I only plan to invest around 500 to 700 dollars initially into this potential "hobby".
About your starting investment into day trading though, that's fine if you think that $500-$700 is just throwaway money to you. Because like I said, expect to lose a bunch of your trades at first. I suggest going a bit lower though. But hey, if you're that wealthy, then go ahead.
If anyone has any particularly good resources/guides that they found extremely helpful as they started out daytrading I would be extremely grateful if you posted them.

Head over to the trading section on
