The benefit of choosing a regulated broker is that this will ensure that you, as a trader, are protected to the full extent of the law in your country. For instance, in 2018 the European Securities and Markets Authority (ESMA) introduced a range of legislation protecting retail trading clients, which all European Forex brokers must abide by. This legislation includes limits on available leverage, volatility protection, negative balance protection and more.
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.
