Very few people succed with daytrading - it's NOT something that you simply "look into" and start doing.
Success doesn't only require an intellectual capacity to understand A LOT of information in very little time but it also requires that you have a type of emotional stability that is very rare. You also need a genuine interest in both economics and psychology - your own and others.
To ask a question about daytrading in hopes of making a quick buck, without having years of theorethical knowledge and practical investing experience, is just a testament that you have no idea what it's all about and that you should stay away.
With that said, losing money is a great way when it comes to determining if you have the right temperament for daytrading. You'll need to read, read, read, every day but you also need to do a lot of trades - both successful and not successful ones - and keep on learning and improving.
It's good if you have a big pile of money for "educational purposes" and be comfortable with not just the thought but also the reality of losing it.
