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.
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.
