The Ouroboros

AI-powered trading agent for global stock markets with self-evolution capabilities.

Quick Start

# Setup
pip install -e ".[dev]"
cp .env.example .env
# Edit .env with your KIS and Gemini API credentials

# Test
pytest -v --cov=src

# Run (paper trading)
python -m src.main --mode=paper

Documentation

• Workflow Guide — Git workflow policy and agent-based development
• Command Reference — Common failures, build commands, troubleshooting
• Architecture — System design, components, data flow
• Context Tree — L1-L7 hierarchical memory system
• Testing — Test structure, coverage requirements, writing tests
• Agent Policies — Prime directives, constraints, prohibited actions

Core Principles

1. Safety First — Risk manager is READ-ONLY and enforces circuit breakers
2. Test Everything — 80% coverage minimum, all changes require tests
3. Issue-Driven Development — All work goes through Gitea issues → feature branches → PRs
4. Agent Specialization — Use dedicated agents for design, coding, testing, docs, review

Markets Supported

• 🇺🇸 United States (NASDAQ, NYSE, AMEX)
• 🇯🇵 Japan (TSE)
• 🇭🇰 Hong Kong (SEHK)

Critical Constraints

⚠️ Non-Negotiable Rules (see docs/agents.md):

• src/core/risk_manager.py is READ-ONLY — changes require human approval
• Circuit breaker at -3.0% P&L — may only be made stricter
• Fat-finger protection: max 30% of cash per order — always enforced
• Confidence < 80 → force HOLD — cannot be weakened
• All code changes → corresponding tests → coverage ≥ 80%

Contributing

See docs/workflow.md for the complete development process.

TL;DR:

1. Create issue in Gitea
2. Create feature branch: feature/issue-N-description
3. Implement with tests
4. Open PR
5. Merge after review
