When you trade forex, you're effectively borrowing the first currency in the pair to buy or sell the second currency. With a US$5-trillion-a-day market, the liquidity is so deep that liquidity providers—the big banks, basically—allow you to trade with leverage. To trade with leverage, you simply set aside the required margin for your trade size. If you're trading 200:1 leverage, for example, you can trade £2,000 in the market while only setting aside £10 in margin in your trading account. For 50:1 leverage, the same trade size would still only require about £40 in margin. This gives you much more exposure, while keeping your capital investment down.
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.
These currency pairs, in addition to a variety of other combinations, account for over 95% of all speculative trading in the forex market. However, you will probably have noticed the US dollar is prevalent in the major currency pairings. This is because it’s the world’s leading reserve currency, playing a part in approximately 88% of currency trades.
Forex day trading is usually used in order to eliminate the need to pay fees for keeping a position overnight. These fees are referred to as 'Swaps'. In some cases, the swaps could be positive, and a trading strategy based on acquiring assets with positive swaps is referred to as a 'Carry Trade', however this strategy is beyond the scope of this article. Day traders hold a lot of importance for the Forex market.
Unlike stock markets, which can trace their roots back centuries, the forex market as we understand it today is a truly new market. Of course, in its most basic sense - that of people converting one currency to another for financial advantage - forex has been around since nations began minting currencies. But the modern forex markets are a modern invention. After the accord at Bretton Woods in 1971, more major currencies were allowed to float freely against one another. The values of individual currencies vary, which has given rise to the need for foreign exchange services and trading.
