We start with understanding the fundamental aspects of a market. Fundametal analysis often times portends a major price move way ahead of the technical signals. The trader who is aware of such a potential situation will have a big advantage over traders who are strictly technical in their approach.
Knowledge of fundamentals in a particulat market also allows a trader to develop an understanding and with that a degree of conviction when a trend emerges. This knowledge increases you ability to stay with a winning trade. When you are aware of the fundamental situation you have an edge at perceiving how the market responds to "new information".
