However, since the Forex market is a global market, it means there is always a part of the world that is awake and conducting business, and during these hours their currencies tend to experience the most movement. For example, currency pairs involving the US dollar experience the most movement during US business hours (16:00 to 24:00 GMT), while the Euro, Pound, Swiss Franc and other European currencies experience the most movement during European business hours, (8:00 and 16:00 GMT).
According to the Bank for International Settlements, the preliminary global results from the 2019 Triennial Central Bank Survey of Foreign Exchange and OTC Derivatives Markets Activity show that trading in foreign exchange markets averaged $6.6 trillion per day in April 2019. This is up from $5.1 trillion in April 2016. Measured by value, foreign exchange swaps were traded more than any other instrument in April 2019, at $3.2 trillion per day, followed by spot trading at $2 trillion.
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.
