About me

I’ve been building high-frequency trading software for the past 10 years. Primarily using C++, for the core system, which always runs in a collocated server next to the exchange.

I'm a passionate software engineer with a deep interest in the world of electronic trading. With extensive experience in the field, I have developed a keen understanding of the complexities and challenges that traders face in today's fast-paced, high-frequency trading environment.

My journey in electronic trading began with my work at a proprietary trading firm, where I was involved in developing and optimizing high-frequency trading systems. This experience gave me a firsthand look at the need for tools that provide real-time insights into trading operations, leading to the creation of VisualHFT.

In addition to my work in electronic trading, I have a broad background in software development, with skills in a range of programming languages and technologies. I am always eager to learn and explore new areas, and I believe in the power of open-source software to drive innovation and collaboration.

Through VisualHFT, I hope to contribute to the trading community and provide a valuable tool for traders and developers alike. I welcome feedback and contributions to the project and look forward to seeing how it evolves with the input of the community.


The inception of VisualHFT was driven by a need for transparency and control in high-frequency trading operations. As the core high-frequency trading system operates in a collocated server with minimal human interaction, it was crucial to develop a mechanism that could provide real-time insights into the system's operations.

VisualHFT was designed as a visualization dashboard to fulfill this need. It provides a real-time view of the trading system's operations, including the volume and nature of orders being sent, the state of the market, and the ability to control some strategy parameters.

The goal was to create a tool that could offer a quick, comprehensive snapshot of what was happening in the trading system at any given moment. This allowed for more informed decision-making and improved operational control, even in a high-speed, automated trading environment.

Over time, VisualHFT has evolved to support a broader range of trading operations, not just high-frequency trading. However, its core purpose remains the same: to provide a clear, real-time view of trading operations, enabling users to make informed decisions and maintain control over their trading strategies.

How to Install and Run the project

  1. Prerequisites: Ensure you have the following software installed on your machine:
  • .NET Framework 7.0
  1. Clone the Repository: Clone the VisualHFT repository to your local machine using the following command in your terminal: git clone
  2. Start the GUI: Finally, navigate to the root of the project and run the VisualHFT GUI. You should now be able to see real-time trading data in the GUI.

Enterprise-Level Data Feed Integrations

VisualHFT is architecturally designed with a modular and extensible framework, making it an ideal solution for enterprise-level systems that rely on diverse data sources. Whether your infrastructure leverages sophisticated messaging systems like Kafka, RabbitMQ, the FIX protocol via QuickFIX, or any other advanced data transmission method, VisualHFT stands ready to assimilate and visualize the data with precision. It's pertinent to note that, in this modular integration mode, the primary focus is on the visualization of market data.

Why I decided to open the project and the motivations

The decision to open-source VisualHFT was driven by a desire to contribute to the broader trading community and to foster innovation in the field of high-frequency trading.

Having worked extensively in the realm of electronic trading, I recognized the need for a tool that could provide real-time insights into the operations of a high-frequency trading system. While the core trading system operates with minimal human interaction, having a clear, real-time view of its operations is crucial for informed decision-making and effective control.

VisualHFT was developed to meet this need. However, I realized that its potential could be greatly amplified if it were open to the broader community. By open-sourcing VisualHFT, I aimed to provide a valuable resource for other traders and developers, enabling them to understand better and navigate the complex world of high-frequency trading.

Moreover, I believe that innovation thrives in a collaborative environment. By making VisualHFT open-source, I hope to encourage others to contribute their ideas and improvements, driving the project forward and ensuring it continues to evolve in line with the needs of the trading community.

Things to improve

  • documentation and wiki page.
  • code architecture.
  • be sure to maintain a MVVC pattern.
  • be able to add more UI (ie: web-base UI)
  • generalization of the strategy parameters and their UI elements.
  • scalability (able to be used by multiple users at the same time)
  • more real-time analytics and risk measurements
  • add unit tests
  • Ability to have a FIX network sniffer as input data (as an alternative to websockets)
  • Security: even though these kinds of applications run inside a private network, there is no security at all involved.


If you are interested in reporting/fixing issues and contributing directly to the code base, please see for more information on what we're looking for and how to get started.

Important: We will not accept any changes to any of the existing input json message format. This is fixed and cannot be changed. The main reason for this is that we can break all existing installations of this system. Unless there is a “very strong” case that needs to be addressed, and all the community agrees upon that. However, we could accept having new json messages, to be parsed and processed accordingly, without breaking any of the existing ones.*
