The main difference between a Forex broker and a Forex dealer is in their role in the Forex market.

A Forex broker acts as an intermediary between the trader and the market, providing a platform for trading currencies. They offer traders access to the Forex market and execute trades on their behalf. Brokers earn money by charging a spread, which is the difference between the buy and sell prices of a currency pair.

On the other hand, a Forex dealer is a financial institution that buys and sells currencies on its own behalf. Dealers operate in the interbank market, which is a network of banks and financial institutions that trade currencies with each other. Dealers typically have access to better pricing and liquidity than individual traders, and they use their expertise to make profits by taking advantage of market fluctuations.

While brokers and dealers both play important roles in the Forex market, they operate in different ways and cater to different types of traders. Brokers are more suited for retail traders, while dealers cater to institutional clients and high-net-worth individuals.
