Level 3 Data

Data

Level 3 data, within the context of cryptocurrency, options trading, and financial derivatives, represents the highest tier of market information, typically encompassing proprietary data feeds and direct exchange connectivity. It moves beyond publicly available top-of-book quotes and order book snapshots to provide granular insights into order flow, including hidden liquidity, internal order books, and potentially, indications of interest. Access to this data is generally restricted to institutional traders, high-frequency trading firms, and market makers due to its cost and complexity, offering a significant advantage in price discovery and execution strategy.
