大时代：自进化多智能体交易系统

📌 Visit the 大时代 website

![System Demo](./docs/assets/bigtime_demo.gif) 大时代 is an open-source financial trading agent framework that combines multi-agent collaboration, run-scoped workspaces, and memory to support both backtests and live trading workflows. The repository name and CLI entrypoints still use `evotraders` for compatibility, but the product-facing branding now follows the 大时代 naming used by the reference branch. --- ## Core Features **Multi-agent trading team** Six roles collaborate like a real desk: four specialist analysts (fundamentals, technical, sentiment, valuation), one portfolio manager, and one risk manager. **Continuous learning** Agents can persist long-term memory with ReMe, reflect after each cycle, and evolve their decision patterns over time. **Backtest and live modes** The same runtime model supports historical simulation and live execution with real-time market data. **Operator-facing UI** The frontend exposes the trading room, runtime controls, logs, approvals, agent workspaces, and explain/news views.

--- ## Current Architecture The repository is currently in a transition from a modular monolith to split service surfaces. The split-service path is the default local development mode. Current app surfaces: - `backend.apps.agent_service` on `:8000`: control plane for workspaces, agents, skills, and guard/approval APIs - `backend.apps.trading_service` on `:8001`: read-only trading data APIs - `backend.apps.news_service` on `:8002`: read-only explain/news APIs - `backend.apps.runtime_service` on `:8003`: runtime lifecycle APIs - `backend.apps.openclaw_service` on `:8004`: read-only OpenClaw facade - WebSocket gateway on `:8765`: live event/feed channel for the frontend The most important runtime path today is: `frontend -> runtime_service/control APIs -> gateway/runtime manager -> market service + pipeline + storage` Reference notes for the migration live in [services/README.md](./services/README.md). --- ## Quick Start ### 1. Install ```bash # clone this repository, then: cd evotraders # backend runtime dependencies uv pip install -r requirements.txt # install package entrypoint in editable mode uv pip install -e . # optional # uv pip install -e ".[dev]" # pip install -e . ``` Frontend dependencies: ```bash cd frontend npm ci cd .. ``` Production deployment should prefer `requirements.txt` for backend and `npm ci` for frontend so the pulled environment matches the checked-in lockfiles and version pins. ### 2. Configure environment ```bash cp env.template .env ``` The root `env.template` is the canonical local template. A `.env.example` is also kept in the repo for reference. Minimum useful variables: ```bash # watchlist TICKERS=AAPL,MSFT,GOOGL,NVDA,TSLA,META,AMZN # market data FIN_DATA_SOURCE=finnhub FINANCIAL_DATASETS_API_KEY= FINNHUB_API_KEY= POLYGON_API_KEY= # agent model OPENAI_API_KEY= OPENAI_BASE_URL= MODEL_NAME=qwen3-max-preview # memory (optional unless --enable-memory is used) MEMORY_API_KEY= ``` Notes: - `FINNHUB_API_KEY` is required for live mode. - `POLYGON_API_KEY` enables long-lived market-store ingestion and refresh helpers. - `MEMORY_API_KEY` is only required when long-term memory is enabled. For a production-style local start flow, you can also use: ```bash ./start.sh ``` ### 3. Start the stack Recommended local development flow: ```bash ./start-dev.sh ``` This starts: - `agent_service` at `http://localhost:8000` - `trading_service` at `http://localhost:8001` - `news_service` at `http://localhost:8002` - `runtime_service` at `http://localhost:8003` - gateway WebSocket at `ws://localhost:8765` Then start the frontend in another terminal: ```bash evotraders frontend ``` Open `http://localhost:5173`. You can also run services manually: ```bash python -m uvicorn backend.apps.agent_service:app --host 0.0.0.0 --port 8000 --reload python -m uvicorn backend.apps.trading_service:app --host 0.0.0.0 --port 8001 --reload python -m uvicorn backend.apps.news_service:app --host 0.0.0.0 --port 8002 --reload python -m uvicorn backend.apps.runtime_service:app --host 0.0.0.0 --port 8003 --reload python -m backend.main --mode live --host 0.0.0.0 --port 8765 ``` ### 4. Run backtest or live mode from CLI Backtest: ```bash evotraders backtest --start 2025-11-01 --end 2025-12-01 evotraders backtest --start 2025-11-01 --end 2025-12-01 --enable-memory evotraders backtest --config-name smoke_fullstack --start 2025-11-01 --end 2025-12-01 ``` Live: ```bash evotraders live evotraders live --enable-memory evotraders live --schedule-mode intraday --interval-minutes 60 evotraders live --trigger-time 22:30 ``` Help: ```bash evotraders --help evotraders backtest --help evotraders live --help evotraders frontend --help ``` ### Offline backtest data If you want a quick backtest demo without external market APIs, download the offline bundle and unzip it into `backend/data`: ```bash wget "https://agentscope-open.oss-cn-beijing.aliyuncs.com/ret_data.zip" unzip ret_data.zip -d backend/data ``` --- ## Runtime Data Layout - Long-lived research data lives in `data/market_research.db` - Each run writes run-scoped state under `runs//` - `runs//BOOTSTRAP.md` stores run-specific bootstrap values and prompt body - `runs//state/runtime_state.json` stores runtime snapshot state - `runs//team_dashboard/*.json` is a compatibility/export layer for dashboard consumers, not the primary runtime source of truth Optional retention control: ```bash RUNS_RETENTION_COUNT=20 ``` Only timestamped run folders like `YYYYMMDD_HHMMSS` are pruned automatically. Named runs such as `live`, `smoke_fullstack`, or `reload_demo_*` are preserved. --- ## Frontend Service Routing The frontend always uses the control plane and runtime APIs, and can optionally call split services directly for read-only data. Useful frontend env vars: ```bash VITE_CONTROL_API_BASE_URL=http://localhost:8000/api VITE_RUNTIME_API_BASE_URL=http://localhost:8003/api/runtime VITE_NEWS_SERVICE_URL=http://localhost:8002 VITE_TRADING_SERVICE_URL=http://localhost:8001 VITE_WS_URL=ws://localhost:8765 ``` If these are not set, the frontend falls back to its local defaults and compatibility paths where available. --- ## Decision Flow ```text Market data -> independent analyst work -> team communication -> portfolio decision -> risk review -> execution/settlement -> reflection/memory update ``` The runtime manager also tracks: - agent registration and status - pending approvals - run events - current session key --- ## Custom Configuration ### Add or change analyst roles 1. Define the analyst persona in [backend/agents/prompts/analyst/personas.yaml](./backend/agents/prompts/analyst/personas.yaml) 2. Register the role in [backend/config/constants.py](./backend/config/constants.py) 3. Optionally add/update the frontend seat metadata in [frontend/src/config/constants.js](./frontend/src/config/constants.js) Example persona entry: ```yaml comprehensive_analyst: name: "Comprehensive Analyst" focus: - multi-factor synthesis preferred_tools: - get_stock_price - get_company_financials description: | A generalist analyst that combines multiple signals. ``` ### Configure per-agent models Model overrides are configured in `.env`: ```bash AGENT_SENTIMENT_ANALYST_MODEL_NAME=deepseek-v3.2-exp AGENT_TECHNICAL_ANALYST_MODEL_NAME=glm-4.6 AGENT_FUNDAMENTALS_ANALYST_MODEL_NAME=qwen3-max-preview AGENT_VALUATION_ANALYST_MODEL_NAME=Moonshot-Kimi-K2-Instruct AGENT_RISK_MANAGER_MODEL_NAME=qwen3-max-preview AGENT_PORTFOLIO_MANAGER_MODEL_NAME=qwen3-max-preview ``` ### Run-scoped bootstrap config Each run can override defaults through `runs//BOOTSTRAP.md`. The front matter is parsed by [backend/config/bootstrap_config.py](./backend/config/bootstrap_config.py) and can define values such as: ```yaml tickers: - AAPL - MSFT initial_cash: 100000 margin_requirement: 0.5 max_comm_cycles: 2 schedule_mode: daily trigger_time: "09:30" enable_memory: false ``` Initialize a run workspace with: ```bash evotraders init-workspace --config-name my_run ``` --- ## Project Structure ```text evotraders/ ├── backend/ │ ├── agents/ # agent roles, prompts, skills, workspaces │ ├── api/ # FastAPI routers │ ├── apps/ # split service surfaces │ ├── core/ # pipeline, scheduler, state sync │ ├── runtime/ # runtime manager and agent runtime state │ ├── services/ # gateway, market/storage/db services │ └── cli.py # Typer CLI entrypoint ├── frontend/ # React + Vite UI ├── shared/ # shared clients and schemas for split services ├── runs/ # run-scoped state and dashboards ├── data/ # long-lived research artifacts └── services/README.md ``` --- ## Testing Backend tests live under `backend/tests` and cover service apps, shared clients, domains, routing, enrichment, gateway support, and runtime support.
