Day trading is often said to be a difficult or even impossible way of making money out of financial markets. The detractors often claim that unpredictable market movements during the fast intra-day timeframes make it nearly impossible to find a reliable day trading strategy, and that short timeframes are too fast to trade on, so that there is little time to analyse the market and form a well-considered plan of action. They also typically quote the supposed high number of investors who fail to make money and who either later quit or move on to other kinds of trading.
