Technical Concepts
Market Depth
Market's ability to handle large orders without significant price impact
Definition
Market depth refers to the market's ability to sustain large orders without significantly impacting price. Deep markets have high liquidity and low price impact for large trades.
Example
ETH/USDC has deep market depth on major exchanges, so trading $1M causes minimal price impact, unlike small altcoin pairs.
What to check
Treat it as infrastructure: understand what it automates, what trust assumptions remain, and how failures propagate. The main checks are: Shallow markets; High slippage; Liquidity fragmentation.
Risks to Consider
- Shallow markets
- High slippage
- Liquidity fragmentation
Common Questions
What does Market Depth mean in DeFi?
Market Depth means Market's ability to handle large orders without significant price impact. The useful question is not only the definition, but how the mechanism changes risk, return, liquidity, or governance for the user.
How is Market Depth used in practice?
A practical example: ETH/USDC has deep market depth on major exchanges, so trading $1M causes minimal price impact, unlike small altcoin pairs.
What should I check before relying on Market Depth?
Check shallow markets, high slippage, liquidity fragmentation. Also verify liquidity, oracle assumptions, admin controls, and whether the protocol has been tested during stressed markets.
