The New York Stock Exchange (NYSE) is renowned as an auction market where buyers and sellers come together, rather than a dealer market. It operates via a system that focuses on market makers to facilitate trading, making it both efficient and dynamic. In practice, the NYSE is at the forefront of innovation in trading technology. It expanded its systems to include platforms like superDOT (Designated Order Turnaround), allowing for more efficient trades. This system is critical in attracting significant order flow and ensuring liquidity, establishing the NYSE as a vibrant hub in the financial world.
