A forex broker, also known as a retail forex broker or currency trading broker, is an intermediary who buys and sells currency pairs for a commission.
Forex brokers essentially work as the middle-man between a forex trader and the interbanks, or network of banks, to enable you to buy and sell foreign currencies. A forex broker works as an intermediary between you and the interbank system. A Forex broker who uses a dealing desk and is registered as a Retail Foreign Exchange Dealer and Futures Commission Merchant (or equivalent in another country) can offset trades.
