The foreign exchange (currency or forex or FX) market exists wherever one currency is traded for another. It is by far the largest market in the world, in terms of cash value traded, and includes trading between large banks, central banks, currency speculators, multinational corporations, governments, and other financial markets and institutions. Retail traders (small speculators) are a small part of this market. They may only participate indirectly through brokers or banks and may be targets of forex scams.
