Depth of Book

Depth

Within cryptocurrency, options trading, and financial derivatives, depth of book refers to the quantity of buy and sell orders available at various price points. It provides insight into market liquidity and potential price volatility, indicating the robustness of order flow. A deeper book, characterized by substantial order sizes at multiple price levels, generally suggests greater liquidity and reduced price impact from large trades. Conversely, a shallow book implies limited liquidity and a higher probability of significant price movements resulting from relatively small order sizes.
