## Limit Order Book Decay

Limit order book decay describes the rate at which limit orders are canceled or executed as market conditions change. In high-frequency trading, order books are dynamic, and orders that are not filled quickly often become stale or irrelevant due to price fluctuations.

A high rate of decay indicates that market participants are constantly adjusting their strategies to account for new information or volatility. This phenomenon is crucial for understanding the true liquidity available to traders, as the visible order book may contain orders that are unlikely to be filled.

Analyzing decay helps market makers optimize their quoting strategies to avoid adverse selection. It is a fundamental component of microstructure analysis, reflecting the speed and responsiveness of the market ecosystem.
