## Order Book Reconstruction

Order book reconstruction is the process of building a historical view of market depth using raw order flow data. This involves processing messages such as limit order additions, cancellations, and executions to track the state of the bid and ask sides.

In the context of cryptocurrency exchanges, this is necessary because most platforms only provide aggregated trade data, not the full history of the order book. Accurate reconstruction allows traders to analyze liquidity, order imbalances, and the impact of large trades.

It is a fundamental task in market microstructure research, as it provides insight into the supply and demand dynamics at different price levels. This data is essential for testing strategies that rely on liquidity provisioning or high-frequency order flow patterns.

Errors in reconstruction, such as missed messages or incorrect state updates, can lead to significant biases in strategy testing. It requires high-performance computing to handle the massive volume of message data typical of modern digital asset exchanges.

Ultimately, a high-fidelity order book is a prerequisite for understanding the mechanics of price discovery and market efficiency.
