Playing the news game is very dangerous as you will start to be influenced by other people's biases and that will inevitably influence your trading, possibly leading you to violate your system rules. Trying to gauge the impact of fundamentals in the markets will rarely provide you with any edge at all. In this day and age information is disseminated instantly, you don't know better than the next person. Plus, sometimes the markets fall on good news and rally on apparently bad news.
Is the US GDP negative for the year? Have the employment numbers been bad, way below expectations for three months in a row? Those things are more important than whether Cyprus is entering a crisis or the president of Greece went to the bathroom. Even then, they won't affect my trading too much because my trades last 4 to 8 weeks in general whereas true bear markets (not short term crashes) develop over months and years.
In my articles and analysis I never talk about events going on in the world, their impact in the markets or anything like that. In general, you can stay away from that useless overdose of information as an Indexes options seller. This brings me back to a piece I wrote back in 2011 which is the perfect complement to this discussion: The Media and Markets' noise
Learn to smell the noise by a mile!
Financial media and Market gurus suck!
