Day trading is so risky that some traders don't even attempt to do it as a means of making a living. The larger the time-frame the safer your money.
Daily trading people earn money, many people are borrowing and trying to make short-term trading. As a result, short-term trading can sometimes be profitable. Sometimes there are good opportunities daily.
Not like they cannot be profitable, but they can be a huge risk. The opportunities are big though and once you are careful enough to know how to handle yourself in your short trade, then you can make some pretty huge bucks.
I am not a day trader and I really do not even have the time to do that, with positioning trading though, which seems a lot better for me as I really do not need to do much while expecting a comeback for the market.
Day trading is like one of the most risky types of trading one can ever do. Most times, I prefer to just invest than day trading. Trading on its own is a huge job, let alone day trading. Except you have a strong mind for huge risk, or you really can forfeit some of your cash, then this is not for a sane person without some crazy technical skills and you just have to be alert to be able to make quick decisions on your trade.
