A community-driven, multi-agent platform for financial applications — typed, async-first, and built for orchestration.

• Async, re-entrant orchestrator: streaming process_user_input can pause for human-in-the-loop (HITL) and resume safely.
• Planner with HITL: pauses on missing info/risky steps via async UserInputRequest, resumes after user feedback to produce an adequate plan.
• Streaming pipeline: Response → ResponseBuffer (buffered vs immediate with stable item_id) → ResponseRouter to UI and Store.
• Agent2Agent (A2A) integration: first-class support via a2a-sdk for agent-to-agent protocols, message schemas, and optional HTTP server interop.
• Conversation memory: in-memory/SQLite stores enable reproducible history, fast "resume from last", and auditability.
• Robustness & extensibility: typed events/errors, router side-effects (e.g., fail task), and clear seams to add agents, stores, transports, and planner logic.

See detailed flow diagrams and design notes in ../docs/CORE_ARCHITECTURE.md.

Set up the environment and verify your install:

uv sync --group dev
uv run python -c "import valuecell as vc; print(vc.__version__)"

Install the package in development mode with all dependencies (including testing tools like pytest, pytest-cov, and diff-cover):

uv sync --group dev

uv sync

• Python >= 3.12
• Dependencies managed via pyproject.toml

Add OKX credentials to .env (or export them before launch):

AUTO_TRADING_EXCHANGE=okx
OKX_NETWORK=paper          # switch to mainnet only after validation
OKX_API_KEY=...
OKX_API_SECRET=...
OKX_API_PASSPHRASE=...
OKX_ALLOW_LIVE_TRADING=false
OKX_MARGIN_MODE=cash       # or cross / isolated

Launch with ./start.sh --exchange okx --network paper to route the Auto Trading agent through OKX. Flip OKX_ALLOW_LIVE_TRADING=true only when you're ready for real execution.
