It is confirmed that only 5% of people earn from daytrading, 95% lose. And it's not about skills, but rather about the fact that there are mainly robots on the market that can do several transactions per second. A person has no chance with them and will always lose. Unless he is lucky and will play just like a robot.
And that is because to become an effective day trader you need to be able to take the right decisions in a matter of seconds and if you cannot do that then it is impossible to be profitable as a day trader.
