Order Book Illiquidity

Definition

Order book illiquidity represents the condition within a financial exchange where the cumulative volume of resting limit orders is insufficient to absorb large trade executions without inducing significant price deviation. In cryptocurrency markets, this state manifests as a thin depth of bids and asks, leading to exaggerated price sensitivity during order fulfillment. Traders navigating these environments often encounter heightened slippage, as the execution of sizable market orders consumes all available liquidity at the top of the book.
