It is possible to buy and sell money from different countries on the foreign exchange market called Forex. Forex currency traders can profit by taking advantage of the dips and swells in the foreign currency market. Capturing these differentials is easier in Forex currency trading than in other trading because the Forex market is open twenty-four hours a day, except for weekends, and it is global, so there are always buyers and sellers available. The traders can be diverse. They can be traders looking for short-term gains, such as day traders or slightly longer investment periods, or they can be foreign investors who are looking to hedge their investments with long term Forex trades.

Forex currency trading is done in amounts of currency called lots, that are usually $100,000 each, and can be purchased on margin. Forex currency trading strategies can be based on technical analysis of the history of the currency price or it can be based on analysis of a particular countrys political climate, tax policy, jobless rate, inflation rate, and other factors of the country. There are many different systems of Forex currency trading.

Forex currency trading is a huge market. Daily trading is estimated at between $1 trillion and $1.9 trillion dollars. Because the amount of money is so huge, its hard to imagine that the market can be manipulated the way a smaller market can be. Forex currency trading is also not overseen by one central agency like the Security Exchange Commission, and each country oversees the Forex currency trading activity within its own country.
