-# QuantDinger Python API Server
+# QuantDinger Python API (backend)
-Python 后端服务,提供金融数据获取、技术指标分析、AI 智能体分析和回测功能。
+Flask-based local-first backend for QuantDinger: market data, indicators, AI analysis, backtesting, and a strategy runtime (with an optional pending-order worker).
-## 项目结构
+This repository is intentionally simple: **no external database is required by default**. Data is stored in a local SQLite file (`quantdinger.db`) created/updated automatically on startup.
-```
+## What you get
+
+- **Multi-market data layer**: factory-based providers (crypto / US stocks / CN&HK stocks / futures, etc.)
+- **Indicators + backtesting**: persisted runs/history in SQLite
+- **AI multi-agent analysis**: optional web search + OpenRouter LLM integration
+- **Strategy runtime**: thread-based executor, with optional auto-restore on startup
+- **Pending orders worker (optional)**: polls queued orders and dispatches signals (webhook/notifications)
+- **Local auth (single-user)**: `/login` with env-configured admin credentials (JWT)

```
-## 快速开始
+## Quick start (local development)
-### 1. 安装依赖
+### Prerequisites
+
+- Python 3.10+ recommended
+
+### 1) Install dependencies
```bash
+cd backend_api_python
pip install -r requirements.txt
```
-### 2. 数据库配置
+### 2) Create your local `.env`
-本系统依赖 MySQL 数据库中的 `qd_addon_config` 表进行配置管理。请确保导入 `update_config_search.sql` 等 SQL 文件以初始化配置。
+Windows (CMD):
-### 3. 启动服务
+```bash
+copy env.example .env
+```
+
+Windows (PowerShell):
+
+```bash
+Copy-Item env.example .env
+```
+
+Then edit `.env` and set at least:
+
+- `SECRET_KEY`
+- `ADMIN_USER`
+- `ADMIN_PASSWORD`
+
+Optional but common:
+
+- `OPENROUTER_API_KEY` (for AI analysis)
+- `FINNHUB_API_KEY` / `SEARCH_GOOGLE_*` / `SEARCH_BING_API_KEY` (for richer data/search)
+- `PROXY_PORT` or `PROXY_URL` (if your network blocks some providers)
+
+### 3) Start the API server
-**开发环境:**
```bash
python run.py
```
-**生产环境(使用 Gunicorn):**
+Default address: `http://localhost:5000`
+
+## Database (SQLite)
+
+- Default file: `backend_api_python/quantdinger.db` (override via `SQLITE_DATABASE_FILE`)
+- Tables are created/updated automatically on startup (see `app/utils/db.py`)
+- `qd_addon_config` exists for backward compatibility, but **this backend reads secrets from `.env` / OS env**, not from the database (see `app/utils/config_loader.py`)
+
+## Frontend integration (Vue dev server)
+
+The Vue dev server proxies `/api/*` to this backend by default:
+
+- Frontend: `http://localhost:8000`
+- Backend: `http://localhost:5000`
+
+Proxy config: `quantdinger_vue/vue.config.js`
+
+## Useful endpoints
+
+```text
+GET /health
+POST /login
+GET /info
+GET /api/indicator/kline
+POST /api/analysis/multi
+```
+
+## Production (optional)
+
+Gunicorn example:
+
```bash
gunicorn -c gunicorn_config.py "run:app"
```
-服务将在 `http://localhost:5000` 启动
+## Troubleshooting
-## 主要功能
-
-### 1. 多维度 AI 分析
-基于多智能体架构 (Multi-Agent Architecture),模拟真实投研团队:
-- **市场分析师**: 技术面分析 (K线, MACD, RSI, 均线)
-- **基本面分析师**: 公司财务、估值、行业地位
-- **新闻分析师**: 实时新闻、舆情分析 (集成 Finnhub + Google/Bing 搜索)
-- **情绪分析师**: 市场情绪评估
-- **风险分析师**: 波动率、流动性风险评估
-- **多空辩论**: 模拟看涨/看跌研究员辩论,提供平衡观点
-
-### 2. 数据获取增强
-- **美股**: 实时行情 (Finnhub/yfinance) + 深度公司资料
-- **加密货币**: 实时行情 (CCXT/Binance) + 项目资讯搜索
-- **A股/港股**: 延迟行情 + 网络资讯搜索补充
-
-### 3. 智能搜索集成
-支持 Google Custom Search 和 Bing Search,自动补全传统数据源缺失的信息(如公司简介、最新突发新闻)。
-
-## API 接口
-
-### 健康检查
-```
-GET /health
-```
-
-### K线数据
-```
-GET /api/indicator/kline
-参数: market (Crypto/USStock/AShare), symbol, timeframe, limit
-```
-
-### AI 多维度分析
-```
-POST /api/analysis/multi
-{
- "market": "USStock",
- "symbol": "NVDA",
- "language": "zh-CN"
-}
-```
-
-## 配置说明
-
-系统配置采用 **数据库 + 环境变量** 混合模式,支持热更新。
-
-### 核心环境变量 (启动参数)
-| 变量名 | 说明 |
-|--------|------|
-| PYTHON_API_HOST | 监听地址 |
-| PYTHON_API_PORT | 监听端口 |
-| MYSQL_HOST | MySQL 主机 |
-| REDIS_HOST | Redis 主机 |
-
-### 数据库配置 (`qd_addon_config` 表)
-大部分业务配置已迁移至数据库,支持动态调整:
-- **API Keys**: Finnhub, Google Search, Bing Search
-- **AI 模型**: OpenRouter 模型选择
-- **系统参数**: 超时时间、重试次数、缓存策略
+- If outbound data/search requests fail, configure `PROXY_PORT` (or `PROXY_URL`) in `.env`.
+- If you don’t want strategies to auto-restore on startup, set `DISABLE_RESTORE_RUNNING_STRATEGIES=true`.
+- If you don’t want the pending-order worker, set `ENABLE_PENDING_ORDER_WORKER=false`.

+# QuantDinger Web UI (Vue 2)
-
Ant Design Vue Pro
-
-An out-of-box UI solution for enterprise applications as a Vue boilerplate. based on
Ant Design of Vue
-
+This is the QuantDinger frontend web UI built with **Vue 2** + **Ant Design Vue**. It connects to the Python backend (`backend_api_python/`) through HTTP APIs to provide charts, indicators, backtests, AI analysis, and strategy management.
-
+> This UI is based on the open-source `ant-design-vue-pro` ecosystem, heavily adapted for QuantDinger.

-[](https://github.com/vueComponent/ant-design-vue-pro/releases/latest)
-[](https://travis-ci.org/vueComponent/ant-design-vue-pro)
+## What you get
-
+- **Dashboards**: summary views and operational panels
+- **Indicator analysis**: Kline charts + indicator editing + backtest history
+- **AI analysis**: multi-agent reports (optional LLM/search, configured on backend)
+- **Trading assistant**: strategy lifecycle + positions/records (depending on backend capability)
+- **Local auth**: login with backend-configured admin credentials

-Overview
-----
+### Prerequisites
-
+- Node.js 16+ recommended
+- Backend running at `http://localhost:5000` (see `backend_api_python/README.md`)
-### Env and dependencies
+### 1) Install dependencies
-- node
-- yarn
-- webpack
-- eslint
-- @vue/cli
-- [ant-design-vue@1.x](https://github.com/vueComponent/ant-design-vue) - Ant Design Of Vue
-- [vue-cropper](https://github.com/xyxiao001/vue-cropper) - Picture edit

-
-> Note: [Yarn](https://yarnpkg.com/) package management is recommended, the exact same version loaded with the demo site of this project (yarn.lock) . but you can also use npm
-
-
-### Project setup
-
-- Clone repo
```bash
-git clone https://github.com/vueComponent/ant-design-vue-pro.git
-cd ant-design-vue-pro
+cd quantdinger_vue
+npm install
```
-- Install dependencies
-```
-yarn install
+### 2) Start dev server
+
+```bash
+npm run serve
```
-- Compiles and hot-reloads for development
-```
-yarn run serve
+Dev server runs at `http://localhost:8000`.
+
+### 3) API proxy (important)
+
+In dev mode, this project proxies `/api/*` to the backend:
+
+- Proxy config: `quantdinger_vue/vue.config.js`
+- Default target: `http://localhost:5000`
+
+If your backend runs on a different host/port, update `vue.config.js` accordingly.
+
+## Production build
+
+```bash
+npm run build
```
-- Compiles and minifies for production
-```
-yarn run build
-```
+The output will be generated under `quantdinger_vue/dist/`.
-- Lints and fixes files
-```
-yarn run lint
-```
+## Notes
+- **CORS**: when using the dev proxy, you typically don’t need extra CORS config.
+- **Login**: use the credentials defined in `backend_api_python/.env` (`ADMIN_USER` / `ADMIN_PASSWORD`).
