A broker is any person or firm that charges a fee in exchange for executing trades for a trader. A Forex broker does not charge a commission for placing a buy or a sell order the way a real estate broker would charge a percentage fee of the total price of a sale. A Forex broker is paid according to the spread or the difference between the traders bid for a currency, and the sellers asking price for that currency. Usually this spread is less than 0.1% or ten pips. (Pips are the smallest movement a currency can make on the Forex. Pips are commonly called referred to as points.) The lower the spread, the less a trader pays a Forex broker for a trade.

The Forex market is global and does not have one central regulatory agency like the Security Exchange Commission. Each country is responsible for the actions of trades in its own country. A Forex broker in America must register with the Commodities Futures Trading Commission (CFTC). While traders are not regulated, Forex brokers are. A Forex broker must be registered as a Futures Commercial Merchant (FCM) before that Forex broker is allowed to accept a deposit for an account from a trader. Once registered, a Forex broker is given an identification number so that a trader can check the status of a Forex broker before hiring that Forex broker. There are such people known as introducing brokers who may solicit traders for a registered Forex broker, but the introducing broker cannot accept a deposit for a traders account. It is a good idea for any trader hiring a Forex broker to check the status of the Forex broker with the authorities.
