Step-by-step explanation:
Securities dealers that commit to continuously offering to buy and sell specific NASDAQ-listed stocks are known as Market Makers. Market Makers provide liquidity and depth to the stock market and ensure that there is always a buy and sell quote for the stocks they cover, which helps in maintaining an orderly market. The role of Market Makers is crucial in the trading ecosystem, enabling investors to execute their trades efficiently on the stock exchanges such as NASDAQ.
The stock exchanges operate as venues where buyers and sellers can trade securities and stocks, and companies must pay a fee to list their stocks. Trading is done via various methods, including the traditional 'Open Outcry' method shown in the video or the more contemporary electronic trading platforms.
