Doing what works
Traders normally use a mix of fundamental, quantitative, and technical techniques with a short term orientation.
I have to emphasize here that successful trading requires careful attention, discipline, and a lot of work

Trading is a time-consuming adventure.  Although there are a number of very famous and successful traders, many individuals ignore the fact that these traders are well equipped to trade and have all day to do so.  Given the time and effort most successful traders put into their trading, the potential for amateurs to reap the same rewards with less effort and fewer resources is very low.

With so much money competing in the one-day to one-year investment time-frame, an individual with a minimal amount of time will probably be more successful finding businesses to own for the long term and not trying to engage in high-octane, almost gambling like behavior.  (The Motley Fool)
