Order Book Mechanics

Definition ∞ Order book mechanics describe the fundamental processes by which buy and sell orders are collected, matched, and executed on a trading exchange. This system displays current bids and asks for an asset, providing insight into market depth and liquidity. Understanding these mechanics is crucial for efficient price discovery and trade execution.
Context ∞ The discussion around order book mechanics in decentralized finance often contrasts traditional centralized exchange models with automated market makers (AMMs). A key debate involves optimizing these mechanisms for speed, fairness, and resistance to manipulation in a permissionless environment. Future developments include hybrid models combining aspects of both order books and AMMs to enhance trading efficiency.
