quote-driven markets what does it include？

Quote-driven markets include financial markets where prices are determined by quotes provided by market makers or dealers, rather than by the forces of supply and demand. These markets typically involve over-the-counter (OTC) trading of securities, such as bonds, currencies, and derivatives. In a quote-driven market, market makers provide quotes for both buying and selling a particular security, and investors can choose to accept or reject these quotes. The market maker earns a profit by buying securities at a lower price and selling them at a higher price, known as the bid-ask spread.
