Liquidity providers, also known as liquidity suppliers, are financial institutions like banks that help increase liquidity on trading platforms. They do this by placing multiple limit orders in the order book. This process helps stabilize the market when large volumes of financial instruments are bought or sold. Both crypto and Forex brokerages, especially those using Straight-Through Processing (STP), rely on liquidity providers to maintain smooth transactions and competitive prices. Because of their scale, liquidity providers often become the primary choice for market participants looking to buy or sell assets.
