The clear history of how currency trade started is unknown. It is said that the whole concept of currency trade was brought about by the Babylonians. Babylonians are thought to be the pioneers of paper money. They started what was known as an IOU system by modifying the barter system of trade. Instead of another product (s) in exchange of a product people started handing out IOU’s that could be redeemed after a predefined period. These IOU’s started changing hands for other IOU’s or products and that is how, supposedly, currency trade began.

People also trade in currency as a business and work to earn profits. They buy the currency when it is ast a lower price and then sell it at a higher price. If conditions are favorable then currencies are also bought at high prices and sold at even higher. The currency trading market is huge and each person is there due to his own reasons.
