## Matching Engine Proximity

Matching engine proximity refers to the degree of physical or logical closeness between a trader's infrastructure and the exchange's core order matching system. In centralized crypto exchanges, this often means utilizing the same cloud availability zone or specialized direct-connect infrastructure.

Proximity directly impacts the speed at which order updates and market data are exchanged. When a trader is closer to the matching engine, they receive market updates faster and their orders reach the queue earlier.

This is a vital factor in determining the priority of order execution in a first-in-first-out matching system. It represents the ultimate spatial advantage in electronic trading.
