Regardless of any accurate fundamental or technical analysis, staying on top of weekly economic events is KEY for a trader. Any news derived from these can completely alter the best analysis carried out, simply because the "big guys" (institutions, hedge funds, smart money) always follow these events, and decide according to their results. Finally, they are the ones that move the market, and you always have to follow them, like it or not.
