Market Depth refers to the ability of a market to sustain large buy or sell orders without causing a significant change in the asset’s price.
Market Depth shows the number of buy (bid) and sell (ask) orders at different price levels for a stock or asset. It reflects the liquidity and strength of demand and supply in the market.
Traders view market depth through the order book (Level 2 data) on exchanges like the National Stock Exchange and Bombay Stock Exchange, regulated by the Securities and Exchange Board of India.
"If many buy and sell orders exist at different price levels for a stock, it has strong market depth and high liquidity."
