In my opinion, maybe it sounds quite pessimistically, it's impossible. The only way one can try it is scalping, however I don't think that it takes only a day. Maybe some professional tradesr from wall street can show others such focuses, but a common trader isn't able to make such amount of money in one day. Guess that it's something from the sphere of fiction, you know. If you're lucky man maybe you can try to do such thing, nobody prohibits you, but I think more that you can reach per day from this amount of money is 100-150$. If one can do that then he must be a very wealthy and lucky person.
