01 / FROM CONNECTION TO EXECUTION

Build the system
you have in mind.

Develop a strategy, put it through a simulator, and choose the components underneath. Every layer has a place in the ecosystem.

SLICK-TRADERC++23

Your strategy.
A place to run.

A trading engine with strategy plugins, pre-trade risk checks, position tracking, and a live dashboard.

03 / MAKE IT YOURS

Start with a library.
Build from there.

Reach for a single component and get to know it. The README is your guide to installation, examples, and current project status.

C++ where it counts.

Queues, byte streams, and networking libraries for the core of your application.

Python in the loop.

Share compatible queues and streams between Python and C++ processes through shared memory.

04 / SUPPORT THE FOUNDATIONS

Support the code.
Grow the ecosystem.

If Slick Quant helps you learn, build, or run a system, sponsorship is a way to support the open-source work behind it.

THE NEXT COMMIT COULD BE YOURS

Built in the open.
Better together.

Code, documentation, benchmarks, or a well-reported bug.
There’s more than one way to move the ecosystem forward.
