Market Depth Proxy

Definition

A market depth proxy serves as an empirical surrogate for the latent liquidity available within a decentralized or order-book-based cryptocurrency exchange. Analysts utilize these measures to infer the potential slippage and execution costs of significant position sizes when real-time order flow data remains opaque or fragmented. By correlating metrics like trade frequency, historical volatility, and price impact, traders estimate the resilience of the order book without direct access to the underlying limit order book depth.
