Colocation and Proximity

Colocation involves placing trading servers in the same data center as the exchange’s matching engine to minimize physical distance and network latency. In high-frequency trading, this provides a critical speed advantage, allowing traders to receive data and execute orders faster than those located further away.

For arbitrageurs, proximity is often the deciding factor in who captures a fleeting opportunity. This practice creates a tiered speed environment, where those with the resources for colocation have a significant edge.

While decentralized protocols aim to remove this advantage, it remains a dominant factor in centralized exchange performance. Understanding the importance of proximity is key to analyzing the competitive landscape of arbitrage.
