It depends on you exactly. Most traders would rather stick majorly with technical analysis in making their decisions, and a little bit of fundamentals most of the time. At least I am talking for myself. Fundamental analysis alone may be good enough for anyone who is entering a long term (long or short position) in the market either after a dip or a bull run but usually for those who are short term traders, technical analysis is basically the main thing that is used to make decisions.
