How to Achieve Ultra-Low Latency in Your Trading Network

In the fast-paced realm of financial markets, where milliseconds can make the difference between profit and loss, “ultra-low latency” signifies the holy grail of network connectivity – the ability to execute trades at lightning speed. 

With nearly two decades of expertise in financial markets connectivity, BSO has consistently helped companies stay competitive by enabling the lowest possible latency in their trading network. Additionally, our strategic partnerships and robust infrastructure have solidified our reputation as a reliable partner for trading firms across the globe.

In this article, we explore the importance of ultra-low latency for trading firms and the steps necessary to achieve it and meet the stringent demands of high-speed trading environments.

The importance of ultra-low latency trading

With ultra-low latency networks, traders can gain a competitive edge by accessing market data and executing trades faster than others, enabling them to capitalise on fleeting opportunities. This is because ultra-low latency network connectivity minimises the time for data to travel between a trader's terminal and the exchange servers.

Across all trading styles, from high-frequency to arbitrage, shaving a few milliseconds off of network latency can translate into significant financial gains. In today’s global market, ultra-low latency connectivity enables trading firms to react swiftly to developments around the world, across borders and time zones. Its importance will only grow as trading technology continues to advance and financial markets become increasingly sophisticated. 

Here are three ways in which ultra-low latency network connectivity can benefit your trading firm:

1. Gain a competitive advantage

Ultra-low latency networks can empower traders to implement sophisticated algorithmic strategies that thrive on high-speed data analysis. This minimises the time it takes to identify and capitalise on fleeting arbitrage opportunities arising from price discrepancies across different markets. 

Additionally, minimising latency reduces the risk of order rejection due to stale data, helping improve overall trade efficiency. These networks can also enable faster position adjustments in response to market fluctuations, thus facilitating portfolio risk management.

2. Increase profitability

The low latency facilitates algorithmic trading, enabling firms to automate complex strategies and react swiftly to market changes, reducing the risk of human error and emotional bias. Many trading strategies rely on complex algorithms that analyse vast amounts of data in real time. 

Ultra-low latency ensures these algorithms receive the latest data and can execute trades with minimal delay, thus maximising profitability. This rapid execution allows trading firms to make profits on a large number of trades, often with razor-thin margins, but collectively significant due to the volume.

3. Enable real-time decision-making 

Ultra-low latency networks can cut through delays and enable real-time decision-making for traders. This is achieved through the rapid processing of market data and quick execution of trades. 

For instance, consider a scenario where a trading algorithm detects a sudden drop in the price of a stock. With ultra-low latency, the algorithm can quickly analyse this information, assess its trading strategy, and execute buy orders to capitalise on the price dip before it corrects. 

Without this minimal latency, the delay in data transmission and processing might have resulted in a lost opportunity (and lost profits). Thus, by reducing latency, you can more effectively make split-second decisions that directly impact your profitability.

How to achieve ultra-low latency in your trading network


Achieving ultra-low latency requires a combination of optimised infrastructure, efficient data transmission, and proximity to exchanges. Let’s delve a bit deeper into the requirements. 

Infrastructure optimisation

Achieving ultra-low latency demands meticulous optimisation of both hardware and software components within your IT infrastructure. This may involve deploying high-performance servers, solid-state drives and low-latency network interface cards. Furthermore, fine-tuning operating systems, network stacks and application software to minimise processing delays is a crucial part of the process.

Data transmission efficiency

Efficient data transmission is a key factor in reducing latency. Strategies like packet minimisation (which involves reducing the number of data packets travelling across the network, and breaking down larger packets into smaller ones for faster transmission and processing) can help reduce transmission times. 

Prioritising critical market data streams over less time-sensitive traffic can also improve latency. This ensures that order execution data reaches its destination before less urgent updates. Implementing advanced protocols like UDP multicast for disseminating market data can further enhance transmission efficiency.

Proximity to exchanges

Physical proximity to major exchanges is pivotal in achieving ultra-low latency. Colocation services, where trading firms can rent space to house their servers in a third-party data centre, can significantly reduce network latency. When opting for colocation hosting, choose a data centre located near a major exchange, minimising the distance your data must travel over public networks. 

Major exchanges often have multiple data centres strategically located in financial hubs like New York, London and Tokyo, allowing trading firms to establish a local presence and minimise the distance data must travel.

3 key steps for enabling ultra-low latency trading

If you’re looking to sharpen your competitive edge through ultra-low latency trading, here are three of the most important steps you’ll need to undertake: 

  1. Conducting latency audits: The first step is to assess your current trading infrastructure and identify your latency baseline. Conduct thorough audits to find bottlenecks that lead to high latency. This involves measuring latency at various points in your system and analysing where improvements can be made. As a result, you’ll be able to pinpoint areas for improvement and prioritise your optimisation efforts for maximum ROI.

  2. High-speed connectivity solutions: Having identified the latency bottlenecks, upgrade your network infrastructure. Start investing in high-speed connectivity solutions like fibre optic cables, satellite connections and microwave links. These solutions will help reduce data transmission times between trading venues and exchanges, enabling you to execute trades faster.

  3. Utilising cutting-edge technologies: Consider employing specialised hardware and software solutions designed for low-latency trading. These include low-latency network interface cards (NICs) and Field-Programmable Gate Arrays (FPGAs) to accelerate data processing and order execution. Additionally, low-latency middleware can help reduce delays in data transmission, facilitating real-time responsiveness.
