Potential Con: Trading currencies is a "macroeconomic" endeavor. A currency trader needs to have a big-picture understanding of the economies of the various countries and their inter-connectedness in order to grasp the fundamentals that drive currency values. For some, it is easier to focus on economic activity to make trading decisions than to understand the nuances and often closed environments that exist in the stock and futures markets where microeconomic activities need to be understood. However, an understanding of a company's management skills, financial strengths, market opportunities and industry-specific knowledge are not necessary in forex trading.

[Note: One of the underlying tenets of technical analysis is that historical price action predicts future price action. Since the forex market is a 24-hour market, there tends to be a large amount of data that can be used to gauge future price movements. This makes it the perfect market for traders that use technical tools.
