Central Limit Order Book

A Central Limit Order Book is a trading mechanism where buy and sell orders are aggregated in a transparent list, and the exchange matches them based on price and time priority. This structure allows for price discovery as participants continuously adjust their bids and asks.

It is the standard model for most centralized exchanges and is increasingly being implemented in decentralized protocols. The order book provides a visual representation of market supply and demand, helping traders make informed decisions.

By maintaining a fair and orderly matching process, it ensures that participants are treated equitably. The order book is the foundation of market microstructure and price discovery.

It provides the necessary transparency for efficient trading.
