The service of the broker you choose, and the platform they offer, is essential in ensuring that you achieve the best trading results. If you were trading on a system that was slow and regularly crashed, for example, you might not be able to enter or exit a trade at the price you want. Instead, it's important to look for a broker that offers high levels of liquidity, low spreads and the ability to execute orders at the price you want (or as close to this as possible).
Forex is a portmanteau of foreign currency and exchange. Foreign exchange is the process of changing one currency into another currency for a variety of reasons, usually for commerce, trading, or tourism. According to a recent triennial report from the Bank for International Settlements (a global bank for national central banks), the average was more than $5.1 trillion in daily forex trading volume.
