Co-Location
Co-location is a practice where a trader's servers are physically placed in the same data center as the exchange's matching engine to minimize network latency. By reducing the physical distance that data must travel, the trader can receive market updates and send orders significantly faster than competitors located further away.
This is a cornerstone of high-frequency trading and latency-sensitive strategies in both traditional finance and modern digital asset exchanges. Co-location provides a distinct competitive advantage, effectively creating a tiered market where those with the fastest access can capitalize on fleeting opportunities.
It highlights the role of physical infrastructure in market microstructure and the ongoing drive for speed. While it enhances liquidity and price efficiency, it also raises questions about market fairness and the barrier to entry for retail participants.
