Fundamental analysis is often used to get an overview of currency movements and to provide a broad picture of economic conditions affecting a specific currency. Most traders rely on technical analysis for plotting entry and exit points into the market and supplement their findings with fundamental analysis.
Currency prices on the Forex are affected by the forces of supply and demand, which in turn are affected by economic conditions. The two most important economic factors affecting supply and demand are interest rates and the strength of the economy. The strength of the economy is affected by the Gross Domestic Product (GDP), foreign investment and trade balance.
