What is forex?

The foreign exchange market – also known as forex or FX – is the world’s most traded market. 

Forex trading is the buying and selling of global currencies. It’s how individuals, businesses, central banks and governments pay for goods and services in other economies. Whenever you buy a product in another currency, or exchange cash to go on holiday, you’re trading forex.

However, the vast majority of forex trades aren’t for practical purposes. Speculative FX traders seek to profit from fluctuations in the exchange rates between currencies, speculating on whether one will go up or down in value compared to another.

The foreign exchange market (forex, FX (pronounced "fix"), or currency market) is a global decentralized or over-the-counter (OTC) market for the trading of currencies. This market determines foreign exchange rates for every currency. It includes all aspects of buying, selling and exchanging currencies at current or determined prices. In terms of trading volume, it is by far the largest market in the world, followed by the credit market.

The foreign exchange market assists international trade and investments by enabling currency conversion. For example, it permits a business in the United States to import goods from European Union member states, especially Eurozone members, and pay Euros, even though its income is in United States dollars. It also supports direct speculation and evaluation relative to the value of currencies and the carry trade speculation, based on the differential interest rate between two currencies.

In a typical foreign exchange transaction, a party purchases some quantity of one currency by paying with some quantity of another currency
