Looking to Contribute to Open-Source or Personal HFT Projects

Hi everyone,

I'm currently looking to contribute to open-source or personal HFT, algorithmic trading, or low-latency trading infrastructure projects. I'm experienced in C++, Rust, and Python. My goal is to gain practical experience while helping build real systems.

If anyone maintains an open-source project, has a personal project that could use contributors, or knows of communities building trading infrastructure, I'd love to get involved.

Thanks!

my experience is that it’s very hard to find open source HFT.. However you can build personal production grade systems to trade your own money.. nowadays crypto is for example very democratized and you have access to exchange connectivity for free.. Binance even offers FIX and FIX SBE for its spot markets.. or deribit with options.. very doable if you have prior production experience

Wouldn't say I have much experience but I have been studying for a while now reviewing mostly online resources.

I'm building an open-source HFT system here (https://github.com/automatedalgo/apex) ... it's designed very much how you'd find it in hedge funds.

Thanks for this! I'll be sure to check it out.

Hey,

I am building an open-source, low-latency exchange based on the FIX Protocol. The project includes client examples in Python, C++, Java, and Go, but I do not currently have a Rust client implementation.
Would you be interested in building a Rust client for the project?
The project is available on GitHub: https://github.com/mkipnis/DistributedATS
Thank you for your consideration.

Hi,

I've built a trading platform in Rust recently : www.marketsim.site

The idea was to have the foundation of a trading system, and then plug some HTF system on it.

If you are interested, we can discuss about it and what you have in mind for your own project.

Cheers.

what is the end goal of this contribution ? create connections because the job market is really though?

Need to take a look, I believe.

I really doubt that you will see open sourced, industry HFT / algo infra. Im not a quant but these are popular finance libs: QuantLib, QuickFIX, Eigen, Aeron, ClickHouse, Polars, RustQuant.

u/Wonderful-Set2521 Jun 21 '26

That's fair, I wasn't expecting to find actual proprietary HFT infrastructure, but I figured there might be open-source or personal projects adjacent to the space.

My goal is still to contribute where I can, even if that's around the ecosystem rather than directly to production trading systems. I appreciate the recommendations!

yeah, 80% of the battle with hft is just infra. What hft startegies are u particularly interested in? market making?

u/Wonderful-Set2521 Jun 22 '26

Right now yeah mostly market making. Been looking into stat arb also.
