Market Depth

Trading

Quick Definition

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.

Detailed Explanation

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.

Key Components of Market Depth

  • Bid Orders: Buy orders at various prices
  • Ask Orders: Sell orders at various prices
  • Order Quantity: Number of shares at each level

Why Market Depth Matters

  • Indicates market liquidity
  • Helps traders understand price movements
  • Shows supply-demand balance

High vs Low Market Depth

  • High Depth: Large orders without major price change
  • Low Depth: Small orders can move price significantly

Example
