Unlike a stock market, the foreign exchange market is divided into levels of access. This is due to volume of transactions. Central banks of various countries also participate in the foreign exchange market to align currencies to their economic needs.

There are two types of retail brokers who participate in the foreign exchange market such as the brokers offering speculative trading and brokers offering physical delivery of the bought currency. The foreign exchange rate fluctuations are generally caused by actual currency flows as well as by expectations of changes in currency flows caused by changes in GDP growth, inflation, interest rates, budget and trade deficits or surpluses and other economic conditions of that particular country. The foreign currencies are traded against one another; each pair of currencies thus constitutes an individual product. Although exchange rates are affected by many factors, in the end, currency prices are a result of supply and demand forces, thus its value, are not influenced by any single element, but rather by several.
