However, despite the practical impossibility of forecasting market movements using fundamental analysis, there is a simple, rational, and fundamental explanation of past market events and shifts after all. Speculative traders who watch the main economic data and have access to sources of financial information can generally forecast the general trend of economic development of various countries fairly easily. Therefore, comparing the economic growth rates of different countries or regions is easy. The trader can determine the main trends in changing national currency rates with greater probability. Due to the inaccurate determination of entry and exit levels, the analysis is useless for short-term speculative operations.
