Can you explain how OTC markets work in detail?

Over-the-counter (OTC) markets are decentralized platforms where securities are traded directly between buyers and sellers, rather than through a centralized exchange. This allows for more flexibility in trading, as transactions can be customized to meet the specific needs of the parties involved. OTC markets are typically used for trading stocks that are not listed on major exchanges, as well as for trading bonds, derivatives, and other financial instruments. Prices in OTC markets are determined by supply and demand, and trades are often facilitated by brokers or dealers. While OTC markets can offer greater liquidity and efficiency for certain securities, they also carry higher risks due to the lack of regulation and transparency compared to traditional exchanges.
