Market Depth vs Liquidity (Comparison)
What It Is
This comparison distinguishes market depth, which measures order book volume at various price levels, from liquidity, which measures how easily assets can be traded.
Why It Matters
Both concepts affect execution quality, slippage, and price stability.
How It Works
Market Depth
- Focuses on order book layers
- Shows how much volume exists at each price
- Indicates resistance to large trades
Liquidity
- Measures ease of trading
- Includes spreads, volume, and depth
- Reflects overall market participation
Key Components
- Order book structure
- Trading volume
- Bid‑ask spreads
- Execution risk
Example
A stock may have high liquidity but shallow depth if most trading occurs near the best bid and ask.
Key Takeaways
- Depth is one component of liquidity.
- Liquidity reflects broader market conditions.
- Both matter for trade execution.
