L2 Data Processing

L2 Data Processing involves the ingestion and interpretation of Level 2 market data, which provides a view of the order book at different price levels. Unlike Level 1 data, which only shows the best bid and ask, L2 data reveals the depth of liquidity and allows for more advanced quantitative analysis.

Processing this data involves updating price levels, managing volume changes, and calculating metrics like market imbalance. Because L2 data is voluminous, efficient processing is required to prevent latency buildup.

Traders use this data to identify support and resistance levels, estimate market impact, and develop execution strategies that account for liquidity constraints. It is essential for any strategy that moves beyond simple market-making or basic price tracking.
