Open Meridian documentation

Open Meridian is the open-source OEMS: the order and execution management system you run yourself, in your own environment, and build on. Traders have their AI agents build the tools their workflow is missing; developers write their bots and analytics in Python. Each plugin talks only to its own sidecar, which carries its credentials and enforces what it may touch, and every change is live in about a second on a development deployment.

This site is how it works. For what it is and why, see open-meridian.com.

What is live, and what is next

Live now: the deployment you run yourself, one identity for every instrument, your own sign-in and permissions, and plugins you write in Python, live as you save them. Next: broker connections, order routing and execution, built in the open.

Where to start

  • Getting started
