Limit Order Book Efficiency

Limit order book efficiency refers to how well an order book reflects the true market value of an asset through its price levels and volume. An efficient book allows for quick price discovery and minimal slippage for traders.

It is characterized by tight spreads and high volume at various price points. Factors such as market fragmentation and the presence of high-frequency traders influence this efficiency.

Monitoring the state of the order book is essential for assessing the health of a trading venue. Efficient books attract more participants, creating a virtuous cycle of liquidity.
