The forex market started in the early 1970s after national currencies started to fluctuate widely and the gold standard for the United States dropped. With this, banks discovered a way to make money by buying currency when it was devalued and selling it after it has strengthened. Prior to that time, a forex market was unnecessary due to the fact that most nations agreed to keep their currency values stable in relation to the U.S. dollar.

The forex market is extremely lucrative today selling about $1.9 trillion in transactions every day 24 hours a day and 5 days a week. Among the most traded currencies are the Euro, the Japanese yen, the British pound, the Australian dollar, the Swiss franc and the US dollar. It is mainly dominated by hedge funds, international banks, corporations, government and investing banks. Individual traders make up a small percent of the market and some people try to invest in the forex market with varying successes.

The basic idea behind forex is to sell one currency and buy another one with the idea of making the trade when believed that the currency bought is going to go up in value compared to the one being sold. If the prediction is correct, another trade can be done in the reverse direction. Therefore selling the currency originally bought and buying the one sold in order to reap the profits.

An example of a forex trade would be if the market reports GBP/EUR 1.2200. In translation, this says that the cost of buying one British pound is 1.22 euros. If an individual trader believes that this course is going to change and the euro will become more valuable that the pound, he will buy 100,000 euros and sell 100,000 pounds. He waits a few weeks to see what happens to the market and discovers that the exchange rate fluctuates to GBP/EUR 1.1.3100. This means that the euro is worth 1.31 and he has made a profit of 0.11 per unit.

Since the world uses money for goods and services, it is always going to be a major force in the financial world. For this, the forex market can be good for those who have studied the finer points and who want to be a part of a profitable venture.
