Yuan is a personal investment operating system designed for individual investors and quantitative traders. It provides a comprehensive, AI-empowered platform for creating, testing, and managing trading strategies across global markets, with a strong emphasis on privacy, cross-platform compatibility, and low cost.

How It Works

Yuan utilizes a serverless, cloud-native architecture with a hybrid-cloud deployment model. Communication between components (terminals) is handled by a star-topology RPC framework, leveraging WebRTC for efficient peer-to-peer connections. It supports a unified data model for global markets, with extensions acting as first-class citizens for adding functionality and market connectivity. Core components include a host manager, storage services (PostgreSQL, Prometheus, Redis), data modeling packages, and various vendor connectors for market access.

Limitations & Caveats

The project is described as "low-level, primitive, and difficult to use" for non-technical users, requiring specific distributions for easier adoption. The GUI is currently in Chinese, with internationalization planned. Specific licensing details for all components need verification for commercial use.
