Order Book Data

Structure

Order book data represents the real-time, electronic record of all outstanding buy and sell limit orders for a specific financial instrument on an exchange. This ledger captures the granular intent of market participants by documenting price levels, corresponding volume, and the side of the trade. Quantitative analysts utilize these snapshots to map supply and demand imbalances, which serve as the foundation for measuring market health and directional bias in both centralized and decentralized environments.
