Market depth represents the cumulative volume of buy and sell orders at different price levels for a particular security. It typically consists of the bid side, representing buy orders, and the ask side, representing sell orders. The level of market depth reflects the liquidity available in the market and the willingness of market participants to buy or sell at specific prices.
Price Discovery Mechanism
Market depth plays a vital role in the price discovery process, whereby supply and demand forces interact to establish equilibrium prices. As buy and sell orders are matched in the order book, price levels adjust based on changes in market participants’ willingness to transact. High levels of market indicate robust liquidity and facilitate efficient price discovery, ensuring that stock prices reflect underlying market fundamentals.
