In the forex industry, a market maker is a person or company that provides both buy and sell prices for a currency pair, thereby ensuring liquidity and facilitating trading. They make money by taking advantage of these price differences, also known as spreads. While these play an important role in keeping deals open, they can also be on the other side of deals, creating potential conflicts of interest. Its main purpose is to ensure that there is always a buyer for every seller in the market, making transactions smooth and easy.
