## Arrival Rate Intensity

Arrival rate intensity, often denoted by the Greek letter lambda, represents the expected frequency of events occurring within a Poisson process. In financial microstructure, it quantifies how many orders or trades are expected to hit the order book per unit of time.

A higher intensity indicates a more active market with higher liquidity throughput. This parameter is dynamic and changes based on market conditions, such as news releases or sudden shifts in sentiment.

Analysts monitor intensity to identify periods of heightened activity that might precede significant price moves. It is a fundamental input for execution algorithms that seek to minimize market impact by adjusting trade sizes based on current flow density.

If the intensity is low, an order might cause a larger price impact because the order book is thin. Conversely, high intensity allows for larger orders to be filled with less slippage.

It serves as a real-time barometer for market participation and liquidity availability. By modeling lambda, traders can optimize their execution strategies to coincide with favorable liquidity conditions.
