## Queueing Theory in Trading

Queueing Theory in Trading is the mathematical study of waiting lines, specifically how orders are handled and processed by an exchange matching engine. It models how order arrival rates and service rates impact the latency and performance of the trading system.

By applying these models, developers can predict system bottlenecks and optimize the design of the matching engine to handle high volume. It helps in understanding how order priority, such as price-time priority, affects execution probability.

This theory is vital for high-frequency trading firms that need to estimate their place in the execution queue. It provides a scientific basis for optimizing order placement strategies in competitive environments.
