+5. **LLM集成** - 自动/手动触发舆情分析
+
+## 运行
+
+```bash
+# 安装依赖
+pip install fastapi uvicorn sqlalchemy apscheduler pandas yfinance
+
+# 启动后端
+cd backend && uvicorn main:app --reload --port 8000
+
+# 前端直接打开 frontend/index.html

+# Stock Buddy 港股AI交易系统
+
+一套完整的港股交易分析系统，支持持仓管理、自动舆情分析、实时交易信号。
+
+## 功能特性
+
+- 📊 **持仓管理** - 记录持仓股票，自动计算盈亏
+- 🤖 **AI舆情分析** - 每日自动分析持仓股票舆情（支持Agent调用）
+- 📈 **策略信号** - v7策略：三维度评分 + 大盘过滤 + 盈利保护
+- 🔍 **手动分析** - 输入任意股票代码，即时生成分析报告
+- ⏰ **定时任务** - 每日9:00自动运行分析
+- 🌐 **Web界面** - 现代化UI，支持移动端
+
+## 技术栈
+
+- **后端**: FastAPI + SQLite + APScheduler
+- **前端**: 原生HTML/CSS/JS
+- **数据源**: yfinance（自动切东方财富备用）
+- **LLM**: 预留Agent接口（测试阶段用规则引擎）
+
+## 快速启动
+
+```bash
+cd stock-buddy
+./start.sh
+```
+
+访问:
+- 前端: http://localhost:8000/app
+- API文档: http://localhost:8000/docs

+```
+
+## 使用指南
+
+### 1. 添加持仓
+
+进入"持仓管理"页面，点击"添加持仓"，输入:
+- 股票名称（如：中芯国际）
+- 股票代码（如：0981.HK）
+- 持仓数量
+- 成本价
+- 选择策略（A/B/C）
+
+### 2. 查看分析
+
+在"总览"页面查看:
+- 实时市值和盈亏
+- 买入/卖出信号
+- 持仓列表
+
+### 3. 手动分析新股票
+
+进入"股票分析"页面:
+1. 输入股票名称或代码
+2. 点击"分析"
+3. 查看综合评分、技术信号、舆情分析
+
+### 4. 每日自动分析
+
+系统每天9:00自动:
+1. 更新持仓股票数据
+2. 生成舆情分析
+3. 计算交易信号
+4. 保存分析结果
+
+也可手动点击"运行分析"触发。
+
+## 策略说明
+
+### v7策略架构
+
+```
+三维度评分
+├── 技术面 (60%): RSI + MACD + 均线系统
+├── 基本面 (30%): 营收/利润/PE快照
+└── 舆情面 (10%): LLM情绪分析
+
+买入条件:
+- 综合评分 ≥ 1.5
+- 成交量连续2日放量
+- 恒生指数 > MA20（大盘过滤）
+
+止损策略:
+- A: 固定12%
+- B: ATR × 2.5 动态
+- C: 混合自适应（按波动率自动选择）
+
+盈利保护:
+- >30%: 保本止损
+- >50%: 锁定10%利润
+- >100%: 宽追踪止损
+```
+
+## API接口
+
+### 持仓管理
+
+```
+GET    /api/positions          # 获取所有持仓
+POST   /api/positions          # 添加持仓
+PUT    /api/positions/{id}     # 更新持仓
+DELETE /api/positions/{id}     # 删除持仓
+```
+
+### 股票分析
+
+```
+POST /api/analyze              # 分析股票
+     Body: {"stock_name": "中芯国际", "ticker": "0981.HK"}
+```
+
+### 实时行情
+
+```
+GET /api/quote/{ticker}        # 获取实时行情
+```
+
+### 任务管理
+
+```
+POST /api/tasks/daily-analysis # 手动触发每日分析
+```
+
+## LLM舆情接入
+
+当前使用规则引擎模拟LLM分析，如需接入真实LLM:
+
+1. 修改 `backend/services/llm_service.py`
+2. 替换 `analyze_sentiment()` 方法为真实API调用
+3. 支持通过Agent生成分析（已预留接口）
+
+```python
+# 调用Agent生成舆情
+from llm_sentiment_agent import generate_prompt
+
+prompt = generate_prompt("中芯国际", "2024-06-01", "2024-06-30")
+# 发送给Agent，获取JSON结果
+```
+
+## 开发计划
+
+- [x] 基础持仓管理
+- [x] 股票数据服务
+- [x] v7策略回测
+- [x] Web界面
+- [x] 定时任务
+- [ ] 真实LLM接入
+- [ ] 邮件/微信推送
+- [ ] 历史回测报告
+- [ ] 多用户支持
