The quantity of buy and sell orders at different prices in the order book.
Market Depth refers to the amount of buy and sell orders available at different price levels within an order book. It shows how much liquidity exists and how easily large trades can be executed without significantly impacting market price.
Deep markets support stable trading, while shallow markets are more prone to volatility.
How Market Depth Works
Market depth displays:
Buy orders (bids) stacked below the current price
Sell orders (asks) stacked above the current price
Total volumes available at each price point
The more orders on both sides, the deeper the market.
Why Market Depth Matters
Low slippage: Large trades cause minimal price impact.
Tight spreads: Active liquidity narrows bid-ask spreads.
Reduced volatility: Strong order books absorb sudden buying or selling pressure.
Better execution quality: Institutions rely heavily on deep markets.
Market depth is essential for evaluating the liquidity of a trading pair.

Summary
Market depth measures the volume of orders at different prices in an order book. It’s a key indicator of liquidity, slippage risk, and overall market stability.
