How do HFTs gain an advantage?

• A. They buy space at data centers close to exchange computers, allowing them to access order flow before the public.
• B. They rely on slower data to execute trades more deliberately.
• C. They use only fundamental analysis of companies.
• D. They trade only during off-peak hours.

Answer: (A)

The advantage comes from minimizing latency: getting market data and submitting orders faster than other participants. By colocating servers in data centers near exchange computers and using ultra-fast connections, high-frequency traders cut the time it takes for information to reach them and for their orders to reach the exchange. This lets their algorithms react to new quotes or changes in the order book in microseconds, often getting priority before slower traders can respond. The other ideas don’t fit this edge—slower data slows performance, fundamental analysis is a long-term approach not about speed, and trading only during off-peak hours doesn’t inherently improve the speed or access to early information.
