The foreign exchange market is the mechanism by which currencies are valued relative to one another, and exchanged. An individual or institution buys one currency and sells another in a simultaneous transaction. Currency trading always occurs in pairs where one currency is sold for another and is represented in the following notation: EUR/USD or CHF/YEN. The exchange rate is determined through the interaction of market forces dealing with supply and demand.

Traders generate profits, or losses, by speculating whether a currency will rise or fall in value in comparison to another currency. A trader would buy the currency which is anticipated to gain in value, or sell the currency which is anticipated to lose value against another currency. The value of a currency, in the simplest explanation, is a reflection of the condition of that country's economy with respect to other major economies. The Forex market does not rely on any one particular economy. Whether or not an economy is flourishing or falling into a recession, there are trading opportunities by either buying or selling the currency. Reactive trading is the buying or selling of currencies in response to economic or political events, while speculative trading is based on a trader anticipating events.

Background

Historically, Forex has been dominated by inter-world investment and commercial banks, money portfolio managers, money brokers, large corporations, and very few private traders. Lately this trend has changed. With the advances in internet technology, plus the industry's unique leveraging options, more and more individual traders are getting involved in the market for the purposes of speculation. While other reasons for participating in the market include facilitating commercial transactions (whether it is an international corporation converting its profits, or hedging against future price drops), speculation for profit has become the most popular motive for Forex trading for both big and small participants.
