We make market microstructure visible.
Most trading platforms show you what happened. VisualHFT shows you why - in real time, down to the microsecond.
We exist because the people who build and run trading systems deserve to see what is actually happening inside them: how algorithms behave under pressure, where liquidity shifts, and what the order flow is really telling you. Not after the fact. Right now.
VisualHFT is a real-time analytics platform for market microstructure - built for quants, by quants.
The Story
VisualHFT started in production, not in a pitch deck.
While building high-frequency trading systems for hedge funds, our founder kept running into the same problem: every time a new algorithm was deployed, there was no good way to see what it was actually doing. Was it performing as expected? Was there a subtle issue buried in the order flow? The only way to find out was to dig through logs after the fact - by which time, the damage was already done.
So he built a tool to fix that. A way to visualize algorithm behavior, market dynamics, and infrastructure health in real time, with microsecond precision.
That tool became VisualHFT.
2015
The first version was an internal tool for understanding what deployed strategies were actually doing under live market pressure.
2019
We released the core platform publicly and let the community push it in directions we could not have planned alone.
Today
VisualHFT is evolving into a commercial platform while staying anchored to the open-source core and the people who use it.
Roadmap
See where we're goingOur goal is simple: make market microstructure observability a standard layer of every trading operation.
Three Pillars
Open-source foundation
Built in the open since 2019. Our core analytics engine is open-source, supported by a growing community of contributors, plugin developers, and quant researchers. The community is a core part of how VisualHFT evolves.
Academic partnerships
We are building partnerships with universities and research groups to advance the study of market microstructure - research data access programs, co-authored papers, and collaboration with quant finance programs. It starts with our Partner Quant Program, already open to contributors today.
Commercial platform
For professionals and institutions who need more. The commercial layer adds enterprise-grade features - AI-powered insights, advanced surveillance, deeper exchange integrations, and dedicated support - built on top of the same open-source foundation.
Built for the people inside the machine

The Founder
Ariel Silahian is a software engineer with over 20 years of experience in electronic trading. Having architected high-performance trading platforms for investment banks and hedge funds, Ariel brings deep, hands-on expertise in the systems that power modern markets.
A published author on building high-performance trading systems and an active independent consultant to financial institutions, Ariel founded VisualHFT to solve a problem that kept coming up throughout a career spent at the intersection of software engineering and quantitative finance: the tools to understand what trading systems are doing in real time simply did not exist.
Now they do.
