In algorithmic trading, latency is the delay between when a trade order is sent and when it’s executed. Even a tiny delay – measured in milliseconds – can affect your profits. Low latency is critical for executing trades at the best prices, reducing slippage, and avoiding missed opportunities. Using a Virtual Private Server (VPS) near major financial hubs helps cut these delays, ensuring faster and more accurate trade execution.
Here’s what you need to know:
- What causes latency? Physical distance, network routing inefficiencies, outdated hardware, and slow internet connections.
- How does VPS help? VPS hosting reduces latency by placing your trading system closer to exchange servers and providing high-performance infrastructure.
- Why does it matter? A delay of just 100ms can lead to higher slippage, missed trades, and outdated market data, all of which reduce profitability.
- Key example: A VPS in Chicago can achieve latency under 0.52ms to the CME exchange, significantly cutting execution times compared to home setups.
For traders, every millisecond counts. A low-latency VPS is an effective way to improve trading performance and profitability.

Main Causes of Latency in Trading Systems
Understanding what causes latency in trading systems is essential for improving performance. Delays in processing trades can directly impact your ability to execute at the best prices. Let’s break down the physical and technical factors that contribute to latency.
Network and Distance Delays
Physical distance plays a significant role in latency. Data traveling through fiber optics moves at about 4.9 microseconds per kilometer. Even a short distance of 200 meters adds roughly 1 microsecond per direction. For instance, a trader located in California placing trades on the CME in Chicago will naturally experience delays due to the distance.
Network routing inefficiencies can further increase latency. As trade orders navigate through multiple internet service providers and routing points, each additional hop adds more delay. Using direct exchange feeds instead of standard internet routes can save 150 to 500 milliseconds. To reduce these delays, traders often use strategies like co-location, which involves placing their trading servers directly within exchange data centers. Additionally, employing Quality of Service (QoS) settings can help prioritize critical trading data over less important traffic.
Hardware and Internet Connection Problems
Latency isn’t just about transmission paths – your hardware and internet connection also matter. Outdated components like CPUs, insufficient RAM, or low-quality network interfaces can become bottlenecks. Every millisecond lost can translate into significant financial losses, with estimates suggesting that delays could cost up to $100 million annually.
Investing in high-performance components can make a noticeable difference:
| Component Type | Standard Performance | Low-Latency Performance | Impact |
|---|---|---|---|
| Enterprise Switches | Tens of microseconds (store & forward) | Hundreds of nanoseconds (cut-through) | 100× faster packet processing |
| Network Interfaces | Standard 1GbE | Specialized 10/25GbE with kernel bypass | Direct hardware-to-application communication |
| Processing Units | General CPUs | FPGAs for specific tasks | Dedicated hardware for trading algorithms |
A stable internet connection is equally critical. Unreliable connections can lead to missed trades or leave open positions unmanaged during volatile markets. To reduce this risk, many traders set up redundancy by using multiple internet service providers. Some even add a 5G wireless connection as a backup to ensure consistent access in case of primary connection failures.
Software and Platform Processing Delays
Even with top-notch hardware and networks, software inefficiencies can still cause delays. Complex algorithms or unnecessary calculations can add milliseconds that are critical in trading.
Order routing is another area where delays can occur. When software decides the best execution venue or routes orders through multiple market makers, each decision introduces additional time. Optimizing order routing algorithms to reduce round-trip times and select the fastest execution venues can significantly improve performance.
"The last five years have seen remarkable changes, primarily driven by hardware improvements such as routers, switches, and advancements in fiber optics."
– Tony Jones, Head of Low Latency Strategy at BSO
Efficient message processing is also key. Trading platforms need to quickly parse incoming market data, apply trading logic, and generate orders for transmission. By optimizing algorithms, reducing code complexity, and improving data structures, platforms can handle high-frequency market data without creating backlogs. This ensures trades are executed swiftly, keeping pace with market demands.
How Latency Affects Algorithmic Trading Results
Latency isn’t just a technical hiccup; in the world of algorithmic trading, it’s a potential profit killer. When milliseconds can mean the difference between winning and losing, the importance of ultra-low-latency setups becomes glaringly obvious.
Execution Speed and Order Accuracy
Speed is the backbone of any successful algorithmic trading strategy. High latency slows down order transmission, which in turn delays execution. And in trading, even a 100ms delay can flip a profitable trade into a losing one.
Studies highlight that shaving off just 1ms of latency can improve trade prices and execution accuracy by 0.1%. Over time, this seemingly small improvement translates into measurable profit gains. Automated trading systems, like Expert Advisors, are particularly vulnerable to these delays. Each millisecond lost diminishes the likelihood of executing at your desired price.
For example, testing conducted by NYCServers revealed that their VPS service reduced order latency by 50% compared to a standard desktop trading setup. This underscores how the right infrastructure can significantly enhance performance.
"The fastest traders win the race." – Johnathan
Beyond execution speed, high latency also increases the risk of slippage and missed opportunities, both of which can erode profitability.
Slippage, Missed Trades, and Lost Profits
Slippage occurs when the price at which your order is executed differs from your intended price. High latency amplifies this risk, particularly during volatile market conditions. For instance, during events like the Non-Farm Payroll (NFP) release, a latency of 20ms might result in execution several pips off target. Compare that to 1ms latency, and the difference could amount to thousands in monthly losses.
Missed trades are another consequence. Imagine your algorithm identifies a perfect setup, but by the time your order reaches the market, the opportunity has slipped away. This is especially damaging for strategies relying on precise entry and exit points. Even minor slippage can disrupt the entire trading logic, throwing your strategy off course.
Trading with Outdated Market Data
In algorithmic trading, decisions are only as good as the data they’re based on. Latency delays can cause your algorithm to act on outdated market information, essentially making decisions based on where the market was instead of where it is. This lag can lead to missed opportunities, higher slippage, and inaccurate executions.
Different market segments have varying tolerance levels for latency. For instance:
- High-frequency equities require latency under 100ms to remain competitive.
- Forex trading can operate within a range of 100–300ms for most strategies.
- Retail stocks also fall within this range, though higher latency increases the risk of slippage.
Using direct exchange data feeds instead of consolidated ones can significantly reduce transmission time – by as much as 150 to 500 milliseconds. This improvement can be the difference between a strategy that thrives and one that consistently underperforms due to poor timing.
| Asset Type | Recommended Latency | Trading Impact |
|---|---|---|
| High-Frequency Equities | Under 100 ms | Essential for competitive price execution |
| Forex | 100–300 ms | Suitable for most algorithmic strategies |
| Retail Stocks | 100–300 ms | Sufficient for retail traders; higher latency risks slippage |
Operating with outdated market data reduces your competitive edge. The faster your data and orders move, the closer your results will align with your backtesting predictions. Low-latency VPS setups are a practical way to mitigate these risks and improve trading outcomes.

How does latency impact high-frequency trading compared to retail trading?
Latency is a key factor in high-frequency trading (HFT), where every millisecond can make or break a trade. HFT strategies rely on lightning-fast order execution to take advantage of small price movements and arbitrage opportunities. Even the tiniest delay might mean missing out on a profitable trade or seeing a dip in earnings.
On the other hand, retail trading is much less dependent on speed. Retail traders often prioritize longer-term strategies or execute trades manually, making ultra-low latency less critical. While faster execution can improve the overall trading experience, higher latency usually doesn’t have a major impact on the performance or competitiveness of retail traders compared to its importance in HFT.
