Where do HFTs typically locate their infrastructure to gain an edge?

• A. Data centers near exchange computers.
• B. Home offices of traders.
• C. Remote international locations.
• D. In the cloud far from exchanges.

Answer: (A)

Speed is everything in high-frequency trading, and the key performance driver is latency—the time it takes for market data to reach a trader and for an order to reach the exchange. Placing servers inside or in close physical proximity to the exchange’s data center minimizes the network distance, reduces queuing delays, and lowers jitter, so information and orders move through the system in as close to real-time as possible. This proximity, often achieved through co-location or proximity hosting, gives a measurable edge because even tiny time savings can affect which trades are executed first.

Other setups introduce more latency and variability. A home office depends on consumer-grade networks with unpredictable routes and slower, less reliable connections. Remote international locations add cross-border routing delays and more points of potential delay. Being in the cloud typically means sharing infrastructure and routing layers, which can introduce extra latency and less predictable performance. For ultra-fast trading, these trade-offs are unacceptable, making the data-center near the exchange the best choice.
