High frequency trading and the war on latency
Technologies That Enable Ultra-Low Latency in HFT
The race for ultra-low latency in high-frequency trading (HFT) has driven innovations aimed at eliminating delays in data transmission and order processing. These advancements are reshaping how trading firms invest in infrastructure to stay competitive.
Here’s a closer look at the technologies making this possible:
Colocation Services
Colocation has become a cornerstone for reducing latency in HFT. By placing trading servers directly within the same data center as an exchange’s matching engine, firms minimize the physical distance data must travel. This setup can cut transmission delays down to just a few microseconds. For instance, some HFT firms colocate their servers mere meters from the NASDAQ or NYSE matching engines, receiving raw market data via multicast feeds over ultra-low-latency fiber connections.
The costs reflect the value of this proximity. The CME Group, for example, charges $12,000 per month, plus a $2,000 setup fee, for client-managed connectivity to its Globex platform at its Aurora, Illinois colocation center. For smaller traders or firms looking to avoid hefty upfront costs, leasing a server within a colocation facility offers a more affordable alternative while still delivering significant latency advantages.
FPGA Hardware
Field-Programmable Gate Arrays (FPGAs) are transforming trading performance by offering hardware-level speed and efficiency. Unlike general-purpose CPUs, FPGAs use dedicated circuits to handle specific tasks, ensuring minimal processing delays and consistent performance.
This precision is vital in HFT, where even microsecond delays can affect trade execution. FPGAs are particularly effective for tasks like parsing market data, running risk calculations, and generating orders. Historically, programming FPGAs required expertise in languages like VHDL or Verilog. However, modern tools now make it easier for firms to adopt FPGA technology without needing highly specialized skills.
Microwave Data Transmission
While fiber-optic cables dominate data transmission, microwave networks offer a faster alternative for certain routes. Microwave signals move through the air almost at the speed of light, bypassing the slower transmission speeds of fiber-optic cables, where light slows down within the glass medium. This speed advantage is especially critical for long-distance data transfers between major trading hubs.
Microwave networks are particularly useful for arbitrage strategies requiring rapid communication between exchanges in different cities. However, they come with challenges, such as the need for relay towers with clear line-of-sight and susceptibility to weather disruptions. To mitigate these issues, firms often build redundancy into their networks. Despite these hurdles, microwave technology remains a key tool for traders who rely on fast, cross-market data flows.
High-Performance VPS Hosting
Virtual Private Server (VPS) hosting has evolved to meet the stringent demands of HFT, complementing advancements in hardware. Trading-focused VPS solutions like QuantVPS provide ultra-low latency by combining dedicated server resources, NVMe storage, and optimized network configurations.
Unlike shared hosting, these VPS platforms allocate specific CPU cores, memory, and bandwidth to ensure consistent performance – an essential feature during volatile market conditions. NVMe storage further accelerates data access compared to traditional hard drives or standard SSDs, enabling faster trade execution.
Network optimization also plays a crucial role. For example, QuantVPS achieves latency as low as 0–1ms by strategically positioning its data centers near major exchanges and liquidity providers. With pricing tiers ranging from $59.99/month for VPS Lite to $399.99/month for Dedicated+, traders can scale their infrastructure efficiently without the high costs of colocation.
These advancements are setting the stage for further optimization in trading systems, pushing the boundaries of what’s possible in high-frequency trading.
How to Optimize Trading Infrastructure for Speed
In high-frequency trading, every microsecond matters. An ultra-low latency system requires careful fine-tuning of every component in your infrastructure. Even the smallest delay can mean the difference between a winning trade and a missed opportunity.
Network Setup Optimization
Your network setup plays a crucial role in reducing latency. Start by minimizing the number of network hops between your trading system and the exchanges. Each additional router or switch introduces delays, so aim for direct connections with dedicated network paths whenever possible. If direct connections aren’t an option, configure your network equipment to prioritize trading traffic. Quality of Service (QoS) settings can ensure that market data and order messages are handled with the highest priority.
Specialized hardware like SmartNICs (e.g., Cisco Nexus SmartNICs) can significantly improve performance. These adapters offload packet processing from the CPU, delivering up to 10x lower latency compared to standard network interface cards. Similarly, employing kernel bypass techniques can reduce operating system overhead, while FPGA systems remain unmatched for achieving latencies in the sub-microsecond range.
These network optimizations set the stage for choosing the right processing and storage components to further enhance speed.
Choosing the Right Hardware and Software
For time-critical operations, FPGA hardware is a game-changer. It can execute certain trading algorithms up to 1,000 times faster than traditional software running on general-purpose CPUs.
When selecting a CPU, prioritize high clock speeds over core count, as many trading applications rely on single-threaded performance. Pair this with NVMe storage, which provides rapid data access to support swift trade execution. Additionally, use the fastest supported RAM with enough capacity to keep vital data in memory, avoiding delays caused by disk swapping.
On the software side, focus on parallel processing and tailor algorithms to your hardware. Efficient order routing and well-optimized code are essential; without them, even the best hardware won’t deliver its full potential.
How to Measure and Monitor Latency
Once your infrastructure is optimized, accurate measurement is critical to ensure every improvement delivers real results. Latency metrics provide insight into how your system performs under real-world conditions.
Tick-to-trade measurements, which track the time from receiving market data to sending an order response, offer a practical way to gauge performance. In competitive markets, even minor increases in latency can have a big impact.
Monitoring network round-trip times is another valuable tool. By measuring the delay between sending a test packet and receiving a response from an exchange, you can identify bottlenecks before they affect trading. For instance, a high-performance PCIe DMA controller can achieve round-trip times of under 640 nanoseconds when transferring data between FPGA-based SmartNICs and the host CPU. While achieving such precision often requires specialized tools, the payoff in ultra-competitive markets is undeniable.
Real-time dashboards that track latency metrics alongside CPU usage, memory performance, network throughput, and storage I/O are invaluable for diagnosing problems. Automated alerts for latency spikes can help you stay ahead of sudden changes in market conditions.
Finally, regular benchmarking against established performance baselines is essential. Over time, software updates, hardware wear, or configuration tweaks can degrade performance. Continuous monitoring and timely adjustments ensure your trading infrastructure remains at peak efficiency.

Traders provide liquidity by placing simultaneous buy and sell orders, but they need to adjust their quotes quickly as prices shift. Ultra-low latency systems make it possible to update orders at lightning speed, reducing the risk of holding positions at unfavorable prices. This speed becomes even more critical during volatile periods when markets can move unpredictably. With faster updates, market makers can react to sudden changes, minimize risk, and maintain profitability.
Arbitrage Trading
Arbitrage trading focuses on exploiting brief price differences across markets before they vanish. To secure a net profit of around 0.1% per trade, traders typically need a gross price spread of 0.3–0.5% after factoring in fees and slippage. Ultra-low latency plays a key role here by reducing slippage, ensuring trades execute as close to the intended price as possible, and preserving narrow margins.
Over time, cryptocurrency markets have become more efficient, leading to a decline in straightforward arbitrage opportunities. This shift has driven traders toward more advanced methods, such as latency arbitrage. This strategy takes advantage of time delays in price updates across different brokers and relies heavily on ultra-low latency setups – think sub-1ms access to broker servers. By exploiting these tiny gaps in market synchronization, traders can capture fleeting opportunities. Similar principles apply to other markets, like futures and forex, where speed remains a decisive factor.
High-Frequency Futures and Forex Trading
Futures and forex markets offer fertile ground for ultra-low latency trading due to their high liquidity and continuous activity. For example, in forex trading, even a latency as low as 0.30ms can significantly reduce slippage, boosting profitability in strategies like scalping or arbitrage. In futures trading, ultra-low latency enables traders to respond almost instantly to price changes, helping them capitalize on short-lived opportunities.
During high-activity periods – such as overlapping trading sessions or major economic announcements – prices can shift so rapidly that only the fastest systems can keep up. Whether it’s momentum-based strategies or mean reversion techniques, rapid execution can make all the difference. In currency markets, ultra-low latency is particularly valuable for strategies like triangular arbitrage, where simultaneous trades exploit fleeting price discrepancies across currency pairs. Faster systems consistently translate to better trading performance in these scenarios.
