## 快速开始
|
||||
|
||||
### 1. 安装依赖
|
||||
以下命令以 **WSL（Linux）** 为例。项目在 Windows 盘时，路径一般为 `/mnt/e/project/stock_cs_v1`；若在 WSL 家目录，则替换为实际路径即可。
|
||||
|
||||
### 1. 安装 PostgreSQL（WSL，首次）
|
||||
|
||||
```bash
|
||||
cd backend
|
||||
python -m venv .venv
|
||||
sudo apt update
|
||||
sudo apt install -y postgresql postgresql-contrib
|
||||
sudo service postgresql start
|
||||
|
||||
# Windows
|
||||
.venv\Scripts\activate
|
||||
# 设置 postgres 用户密码（与 backend/.env 中 PG_PASSWORD 一致）
|
||||
sudo -u postgres psql -c "ALTER USER postgres PASSWORD 'your_password';"
|
||||
```
|
||||
|
||||
# Linux / macOS
|
||||
WSL 每次重启后若数据库未自动运行，需先执行：
|
||||
|
||||
```bash
|
||||
sudo service postgresql start
|
||||
```
|
||||
|
||||
### 2. 安装 Python 依赖（首次）
|
||||
|
||||
```bash
|
||||
cd /mnt/e/project/stock_cs_v1/backend # 按实际路径修改
|
||||
python3 -m venv .venv
|
||||
source .venv/bin/activate
|
||||
|
||||
pip install -r requirements.txt
|
||||
```
|
||||
|
||||
### 2. 配置环境变量
|
||||
**Windows 原生（非 WSL）** 激活虚拟环境：
|
||||
|
||||
```powershell
|
||||
cd backend
|
||||
python -m venv .venv
|
||||
.venv\Scripts\activate
|
||||
pip install -r requirements.txt
|
||||
```
|
||||
|
||||
### 3. 配置环境变量
|
||||
|
||||
```bash
|
||||
cd backend
|
||||
cp .env.example .env
|
||||
```
|
||||
|
||||
编辑 `backend/.env`，至少确认 PostgreSQL 连接信息（也可通过环境变量 `PG_USER` / `PG_PASSWORD` / `PG_HOST` / `PG_PORT` / `PG_DB` 设置）：
|
||||
编辑 `backend/.env`，至少确认 PostgreSQL 连接信息（PostgreSQL 装在 WSL 内时使用 `localhost`）：
|
||||
|
||||
```env
|
||||
PG_USER=postgres
|
||||

```
|

也可通过环境变量 `PG_USER` / `PG_PASSWORD` / `PG_HOST` / `PG_PORT` / `PG_DB` 设置，无需改文件。
|
||||
|
||||
可选：填入 `LLM_API_KEY` 启用大模型分析；填入 SMTP / Server酱 / 企业微信 / PushPlus 启用推送。

基于当前架构，建议以下功能扩展方向：
|
||||
|
||||
一、高价值功能扩展
|
||||
1. 盘中实时监控雷达 ⭐⭐⭐⭐⭐
|
||||
痛点：当前只有收盘后复盘，错过盘中异动机会
|
||||
|
||||
功能点：
|
||||
|
||||
快速拉升监控（5分钟涨幅 >3%）
|
||||
放量突破预警（量比 >3 且突破关键位）
|
||||
涨停打开/炸板追踪
|
||||
连板股实时追踪
|
||||
大单异动（单笔超百万）
|
||||
实现难度：中等（需要分钟线数据源）
|
||||
|
||||
2. 策略回测增强 ⭐⭐⭐⭐⭐
|
||||
痛点：当前只有简单 MA 交叉，无法验证复杂策略
|
||||
|
||||
功能点：
|
||||
|
||||
多因子组合回测（技术+基本面）
|
||||
仓位管理策略（金字塔加仓、止损止盈）
|
||||
参数优化网格搜索
|
||||
夏普比率/最大回撤/胜率等完整指标
|
||||
策略对比（并排显示多条净值曲线）
|
||||
交易明细导出（每笔买卖点、持仓天数、收益率）
|
||||
实现难度：中等
|
||||
|
||||
3. 板块轮动分析 ⭐⭐⭐⭐
|
||||
痛点：只有当日板块涨跌，看不出资金流向趋势
|
||||
|
||||
功能点：
|
||||
|
||||
板块强弱排名趋势（近5日/10日/20日）
|
||||
资金流向桑基图（从哪个板块流向哪个板块）
|
||||
板块生命周期判断（启动期/加速期/衰退期）
|
||||
龙头股自动识别（板块内涨幅+成交额排名）
|
||||
板块联动性分析（相关系数热力图）
|
||||
实现难度：中等
|
||||
|
||||
4. 智能选股增强 ⭐⭐⭐⭐
|
||||
痛点：当前选股策略固定，无法自定义
|
||||
|
||||
功能点：
|
||||
|
||||
可视化选股器（拖拽式多条件组合）
|
||||
选股结果回测验证（该选股规则历史表现）
|
||||
选股策略保存/分享
|
||||
条件预警（符合条件时自动推送）
|
||||
选股结果对比（今日 vs 昨日，哪些股票新入选/退出）
|
||||
实现难度：中高
|
||||
|
||||
5. 持仓归因分析深化 ⭐⭐⭐⭐
|
||||
痛点：当前只有简单盈亏，不知道赚钱/亏钱原因
|
||||
|
||||
功能点：
|
||||
|
||||
收益归因分解：选股能力 vs 择时能力 vs 运气成分
|
||||
持仓时长分析（短线/中线/长线各自胜率）
|
||||
买入理由有效性验证（按理由统计胜率）
|
||||
情绪标签相关性（贪婪/恐惧/理性，各自收益率）

|
||||
|
||||
## 功能概述
|
||||
|
||||
AI对话式分析是Blackdata股票终端的终极功能，通过自然语言与AI助手对话，实现智能选股、持仓诊断、策略建议等功能，无需记忆复杂操作步骤。
|
||||
|
||||
## 核心特性
|
||||
|
||||
### 1. 自然语言理解
|
||||
不需要点击菜单或填写表单，直接用人话描述需求：
|
||||
```
|
||||
❌ 传统方式：进入"选股引擎" → 选择字段 → 设置条件 → 执行
|
||||
✅ AI方式："帮我找近期突破且资金流入的科技股"
|
||||
```
|
||||
|
||||
### 2. 上下文记忆
|
||||
AI会记住对话历史，支持多轮连续对话：
|
||||
```
|
||||
用户：帮我选股
|
||||
AI：[返回10只股票]
|
||||
用户：分析第1只
|
||||
AI：[分析第1只股票，无需再次指定代码]
|
||||
```
|
||||
|
||||
### 3. 智能功能调用
|
||||
AI自动识别意图并调用相应功能：
|
||||
- 选股功能
|
||||
- 持仓诊断
|
||||
- 策略建议
|
||||
- 个股分析
|
||||
- 板块分析
|
||||
|
||||
### 4. 多模态回复
|

|
||||
```
|
||||
|
||||
**AI如何处理**：
|
||||

||||
3. 调用选股引擎

|
||||
|
||||
**回复示例**：
|

|
||||
|
||||
## 使用技巧
|
||||
|
||||
### 技巧1：渐进式提问
|
||||
|
||||
不要一次性问太复杂的问题，可以分步提问：
|
||||
|
||||
```
|
||||
❌ 不好的提问：
|
||||
"帮我找5日涨幅大于10%且量比大于2且RSI小于80的科技股，然后回测这个策略，再给我策略建议"
|
||||
|
||||
✅ 好的提问：
|
||||
用户：帮我找5日涨幅大于10%的科技股
|
||||
AI：[返回结果]
|
||||
用户：量比也要大于2
|
||||
AI：[筛选后返回]
|
||||
用户：回测一下这个策略
|
||||
AI：[回测结果]
|
||||
```
|
||||
|
||||
---
|
||||
|
||||
### 技巧2：利用上下文
|
||||
|
||||
AI会记住对话历史，善用这个特性：
|
||||
|
||||
```
|
||||
用户：帮我选股
|
||||
AI：[返回10只股票]
|
||||
|
||||
用户：分析第1只
|
||||
AI：[分析第1只股票]
|
||||
|
||||
用户：这只股票风险大吗？
|
||||
AI：[针对该股票回答风险]
|
||||
|
||||
用户：给我推荐其他的
|
||||
AI：[推荐选股结果中的其他股票]
|
||||
```
|
||||
|
||||
---
|
||||
|
||||
### 技巧3：明确需求
|
||||
|
||||
问题越明确，回答越精准：
|
||||
|
||||
```
|
||||
❌ 模糊："有什么好股票？"
|
||||
✅ 明确："帮我找近5日涨幅超过10%且量比大于2的股票"
|
||||
|
||||
❌ 模糊："市场怎么样？"
|
||||
✅ 明确："当前半导体板块处于什么阶段？"
|
||||
|
||||
❌ 模糊："我该买什么？"
|
||||
✅ 明确："根据我的持仓情况，推荐一些分散风险的股票"
|
||||
```
|
||||
|
||||
---
|
||||
|
||||
### 技巧4：组合使用功能
|
||||
|
||||
将多个功能串联起来：
|
||||
|
||||
```
|
||||
流程示例：
|
||||
|
||||
1. 用户：当前市场适合什么策略？
|
||||
AI：[分析市场，建议关注半导体]
|
||||
|
||||
2. 用户：帮我找半导体板块的股票
|
||||
AI：[返回10只股票]
|
||||
|
||||
3. 用户：分析第1只
|
||||
AI：[详细分析]
|
||||
|
||||
4. 用户：回测这个选股策略
|
||||
AI：[回测结果]

||||
|
||||
5. 用户：我的持仓有什么风险？

# 事件驱动策略使用说明
|
||||
|
||||
## 功能概述
|
||||
|
||||
事件驱动策略是一种基于公司或行业重大事件进行投资决策的量化策略。通过统计分析历史事件对股价的影响，找出规律并应用于实战。
|
||||
|
||||
**核心理念**：重大事件往往改变市场预期，带来股价波动，提前布局或及时应对可获取超额收益。

|
||||
|
||||
## 五大事件类型
|
||||
|
||||
### 1. 财报发布（Earnings）
|
||||
|
||||
**事件说明**：
|
||||
上市公司定期发布财报（季报、半年报、年报），业绩是否符合预期直接影响股价。
|
||||
|
||||
**事件分类**：
|
||||
- **业绩超预期**（Positive）：实际业绩好于市场预期
|
||||
- **业绩不及预期**（Negative）：实际业绩低于市场预期
|
||||
- **业绩符合预期**（Neutral）：实际业绩与预期一致
|
||||
|
||||
**统计分析**：
|
||||
系统统计历史上所有财报事件，分析：
|
||||
- 财报前N天的股价表现
|
||||
- 财报后N天的股价表现
|
||||
- 后续胜率（上涨概率）
|
||||
|
||||
**典型规律**：
|
||||
|
||||
| 业绩类型 | 财报前表现 | 财报后表现 | 胜率 |
|
||||
|----------|------------|------------|------|
|
||||
| 超预期 | 可能提前上涨 | 继续上涨 | 70%+ |
|
||||
| 不及预期 | 可能高位 | 大幅下跌 | 30%- |
|
||||
| 符合预期 | 平稳 | 小幅波动 | 50% |
|
||||
|
||||
**投资策略**：
|
||||
|
||||
**策略1：财报发布后介入**
|
||||
```
|
||||
条件：
|
||||
- 业绩超预期
|
||||
- 财报发布后1-3天内
|
||||
- 股价尚未大涨（涨幅 < 10%）
|
||||
|
||||
操作：
|
||||
- 买入
|
||||
- 止盈：+15%
|
||||
- 止损：-5%
|
||||
- 持仓周期：5-10天
|
||||
|
||||
历史胜率：68%
|
||||
平均收益：+8.5%
|
||||
```
|
||||
|
||||
**策略2：财报前规避**
|
||||
```
|
||||
如果持有股票，财报发布前：
|
||||
- 业绩确定性高 → 继续持有
|
||||
- 业绩不确定 → 减仓或清仓
|
||||
- 避免赌业绩
|
||||
```

|
||||
```json
|
||||
{
|
||||
"event_types": ["earnings_positive", "insider_increase"],

## 注意事项
|
||||
|
||||
1. **数据来源**：
|
||||
- 当前版本使用模拟数据演示
|
||||
- 实际生产需要接入东方财富、巨潮资讯等数据源
|
||||
|
||||
2. **事件滞后性**：
|
||||
- 公告发布到系统采集有延迟
|
||||
- 建议盘后统一采集
|
||||
|
||||
3. **历史规律不代表未来**：
|
||||
- 统计规律是概率，不是确定性
|
||||
- 需结合基本面和技术面综合判断
|
||||
|
||||
4. **事件真实性**：
|
||||
- 警惕虚假信息
|
||||
- 以官方公告为准
|
||||
|
||||
5. **风险控制**：
|
||||
- 事件驱动策略也有失败概率
|
||||
- 必须设置止损
|
||||
- 控制单票仓位

# 持仓归因分析深化使用说明
|
||||
|
||||
## 功能概述
|
||||
|
||||
持仓归因分析深化模块帮助投资者深入理解盈亏来源，通过多维度分析找出投资中的优势和不足，从而改进投资策略。
|
||||
|
||||
## 五大核心分析
|
||||
|
||||
### 1. 选股能力 vs 择时能力
|
||||
|
||||
**功能说明**：
|
||||
分解投资收益的两大来源，判断是"选对了股票"还是"买卖点把握好"。
|
||||
|
||||
**指标定义**：
|
||||
|
||||
#### 选股能力
|
||||
- **计算方法**：买入后股票的整体涨幅（持有期间市场表现）
|
||||
- **正值**：选对了股票（股票整体上涨）
|
||||
- **负值**：选错了股票（股票整体下跌）
|
||||
- **示例**：
|
||||
```
|
||||
选股能力 +15%
|
||||
→ 买入的股票在持有期间平均上涨了15%
|
||||
→ 说明选股眼光不错
|
||||
```
|
||||
|
||||
#### 择时能力
|
||||
- **计算方法**：买卖价格与理想价格（最低/最高）的接近度
|
||||
- **评分**：100分满分，50分为平均水平
|
||||
- **解读**：
|
||||
- 80-100分：优秀，买在低点、卖在高点
|
||||
- 60-80分：良好
|
||||
- 40-60分：一般
|
||||
- <40分：较差，追高杀跌
|
||||
- **示例**：
|
||||
```
|
||||
择时能力 72分
|
||||
→ 买卖点把握较好
|
||||
→ 平均买入价接近期间低点，卖出价接近高点
|
||||
```
|
||||
|
||||
**综合解读**：
|
||||
|
||||
| 选股 | 择时 | 解读 | 改进建议 |
|
||||
|------|------|------|----------|
|
||||
| 正 | 高（>60） | 完美组合 | 继续保持 |
|
||||
| 正 | 低（<40） | 选股对但买卖点差 | 学习技术分析，改进买卖时机 |
|
||||
| 负 | 高（>60） | 股票选错了 | 改进选股逻辑，加强基本面研究 |
|
||||
| 负 | 低（<40） | 双重失误 | 系统性反思，暂停交易 |
|
||||
|
||||
**实战案例**：
|
||||
```
|
||||
用户A：
|
||||
选股能力：+18.5%
|
||||
择时能力：45分
|
||||
|
||||
分析：
|
||||
- 选股很好，买入的股票都大涨
|
||||
- 但买卖点把握一般，可能追高或过早卖出
|
||||
|
||||
建议：
|
||||
- 保持选股策略
|
||||
- 学习等待回调买入
|
||||
- 设置合理的止盈点（如趋势未破不卖）
|
||||
```

||||
| 周期 | 定义 | 特点 |
|
||||
|------|------|------|
|
||||
| **短线** | ≤5天 | 快进快出，需要盯盘 |
|
||||
| **中线** | 6-30天 | 波段操作，适合上班族 |

|
||||
- 交易次数：50次
|
||||

|
||||
|
||||

|
||||
|
||||
结论：长线胜率和收益都更高，建议降低交易频率
|
||||
```
|
||||
|
||||
**策略建议**：
|
||||
系统会自动推荐表现最好的持仓周期：
|
||||
```
|
||||

|
||||
```
|
||||

|
||||
- 跟风买入
|
||||
|
||||
**有效性判断**：
|
||||
- **有效**：胜率 > 50%
|
||||
- **无效**：胜率 ≤ 50%
|
||||
|
||||
**实战案例**：
|
||||
|
||||
```
|
||||
理由统计：
|
||||

|
||||
|
||||
### 案例2：找到自己的节奏
|
||||
|
||||
**初始困惑**：
|
||||
不知道短线好还是长线好
|
||||
|
||||
**数据分析**：
|
||||
```
|
||||
短线（≤5天）：
|
||||
- 胜率：48%
|
||||
- 平均收益：+1.2%
|
||||
|
||||
中线（6-30天）：
|
||||
- 胜率：71%
|
||||
- 平均收益：+8.5%
|
||||
|
||||
长线（>30天）：
|
||||
- 胜率：80%
|
||||
- 平均收益：+18.3%
|
||||
```
|
||||
|
||||
**结论**：
|
||||
适合长线持有，越拿越赚
|
||||
|
||||
**新策略**：
|
||||
- 减少交易频率
|
||||
- 选择优质股票长期持有
|
||||
- 目标持仓周期：60天以上
|
||||
|
||||

|
||||
|
||||
## 注意事项
|
||||
|
||||
1. **数据质量**：
|
||||
- 至少需要5笔已平仓交易
|
||||
- 买入理由和情绪标签要真实填写
|
||||
|
||||
2. **分析周期**：
|
||||
- 建议每月分析一次
|
||||
- 数据积累越多，分析越准确
|
||||
|
||||
3. **避免过度解读**：
|
||||
- 样本量小时结论可能不可靠
|
||||
- 至少20笔交易后再做重大调整
|
||||
|
||||
4. **结合市场环境**：
|
||||
- 牛市和熊市的策略不同
|
||||
- 分析时考虑大盘走势
|
||||
|
||||
5. **持续改进**：
|
||||
- 归因分析是诊断工具，不是灵丹妙药
|
||||
- 需要根据分析结果调整策略，并持续跟踪

## 高级技巧
|
||||
|
||||
### 技巧1：多策略组合
|
||||
|
||||
不要只依赖单一策略，建议配置3-5个不同风格的策略：
|
||||
|
||||
```
|
||||
策略1：动量突破（激进）
|
||||
策略2：价值洼地（稳健）
|
||||
策略3：反转抄底（逆向）
|
||||
```
|
||||
|
||||
每日执行3个策略，取交集或并集。
|
||||
|
||||
---
|
||||
|
||||
### 技巧2：动态调整阈值
|
||||
|
||||
根据市场环境调整条件阈值：
|
||||
|
||||
```
|
||||
牛市：
|
||||
- 5日涨幅 > 15%（更激进）
|
||||
- 量比 > 3
|
||||
|
||||
震荡市：
|
||||
- 5日涨幅 > 8%（适中）
|
||||
- 量比 > 2
|
||||
|
||||
熊市：
|
||||
- 5日涨幅 > 5%（保守）
|
||||
- 量比 > 1.5
|
||||
```
|
||||
|
||||
---
|
||||
|
||||
### 技巧3：结合板块分析
|
||||
|
||||
选股后，查看"板块分析" → "强弱趋势"：
|
||||
- 优先选择强势板块的股票
|
||||
- 避开弱势板块
|
||||
|
||||
---
|
||||
|
||||
### 技巧4：设置后验条件
|
||||
|
||||
选股后人工复核：
|
||||
- 查看K线形态
|
||||
- 检查基本面
|
||||
- 避开ST、*ST
|
||||
- 避开涨停板（无法买入）
|
||||
|
||||

|
||||
|
||||
## 注意事项
|
||||
|
||||
1. **数据依赖**：
|
||||
- 需要先在"数据中台"入库 `stock_metrics` 表
|
||||
- 数据越完整，选股越准确
|
||||
|
||||
2. **回测陷阱**：
|
||||
- 历史表现不代表未来
|
||||
- 过度优化导致过拟合
|
||||
- 样本外测试很重要
|
||||
|
||||
3. **实盘差异**：
|
||||

|
||||
- 涨停板无法买入
|
||||
- 流动性限制
|
||||
|
||||
4. **风险控制**：
|
||||

||||
|
||||
**使用技巧**：
|
||||
- 持续上涨的板块可能处于主升浪
|
||||
- 涨幅回落的板块可能进入调整期
|
||||
- 成交额放大的板块往往有资金关注
|
||||
|
||||
---
|
||||
|
||||
### 2. 资金流向分析
|
||||
|
||||
**功能说明**：
|
||||
通过桑基图直观展示板块间资金流动，识别资金从哪里流出、流向哪里。
|
||||
|
||||
**使用场景**：
|
||||
- 追踪市场热钱流向
|
||||
- 发现资金流入的新热点
|
||||
- 警惕资金流出的板块
|
||||
|
||||
**操作步骤**：

||||
1. 进入"板块分析" → "资金流向"
|
||||
2. 选择统计周期（1日/3日/5日/10日）
|
||||
3. 查看桑基图和资金流入/流出排行
|
||||
|
||||
**图表解读**：
|
||||
- **左侧**：资金净流出的板块
|
||||
- **中间**：资金池（转换枢纽）
|
||||
- **右侧**：资金净流入的板块
|
||||
- **线条粗细**：代表资金流动量
|
||||
|
||||
**投资策略**：
|
||||
```
|
||||
顺势策略：跟随资金流入的板块
|
||||
逆向策略：关注资金流出但基本面良好的板块（可能超跌）
|
||||
```
|
||||
|
||||
**示例**：
|
||||
```
|
||||
观察到：
|
||||

|
||||
|
||||
### 3. 板块生命周期
|
||||
|
||||
**功能说明**：
|
||||
判断板块当前处于哪个阶段，辅助买卖决策。
|
||||
|
||||
**生命周期阶段**：
|
||||
|
||||
| 阶段 | 特征 | 策略 |
|
||||
|------|------|------|
|
||||
| **启动期** | 刚开始上涨，资金流入加速 | 积极介入，低位布局 |
|
||||
| **加速期** | 持续上涨且加速，成交活跃 | 持有为主，主升浪 |
|
||||
| **衰退期** | 涨幅收窄或开始回调 | 逐步减仓，注意风险 |
|
||||
| **下跌期** | 持续下跌 | 避免介入，等待企稳 |
|
||||
| **震荡期** | 横盘整理，方向不明 | 观望，等待方向明确 |
|
||||
|
||||
**判断依据**：
|
||||
1. **涨跌幅趋势**：
|
||||
- 20日涨幅 > 0 且加速 → 启动期/加速期
|
||||
- 20日涨幅 > 0 但减速 → 衰退期
|
||||
- 20日跌幅 > 5% → 下跌期
|
||||
|
||||
2. **成交额变化**：
|
||||
- 近5日成交额 / 近20日成交额 > 1.2 → 资金流入
|
||||
- < 0.8 → 资金流出
|
||||
|
||||
3. **动量指标**：
|
||||
- 5日涨幅 - 10日涨幅 > 0 → 加速
|
||||
- < 0 → 减速
|
||||
|
||||
**操作步骤**：
|
||||
1. 进入"板块分析" → "生命周期"
|
||||
2. 输入板块名称（如"半导体""新能源""医药"）
|
||||
3. 点击"分析"
|
||||
4. 查看生命周期阶段和建议
|
||||
|
||||
**使用示例**：
|
||||
```
|
||||
板块：半导体
|
||||
阶段：加速期
|
||||
5日涨幅：+8.5%
|
||||
20日涨幅：+23.7%
|
||||
成交额变化：+45.2%
|
||||
|
||||
解读：
|
||||
板块处于主升浪，持续上涨且加速，成交额放大明显。
|
||||
建议：持有为主，可适当加仓龙头股。
|
||||
风险：注意短期涨幅过大，设好止盈位。
|
||||
```
|
||||
|
||||

|
||||
|
||||
### 4. 龙头股识别
|
||||
|
||||
**功能说明**：
|
||||
自动识别板块内的龙头股票（涨幅领先 + 成交额靠前）。
|
||||
|
||||
**识别标准**：
|
||||
1. 近20日涨幅居前
|
||||
2. 日均成交额 > 5亿（流动性好）
|
||||
3. 名称包含板块关键词（简化匹配）
|
||||
|
||||
**操作步骤**：
|
||||
1. 进入"板块分析" → "龙头股"
|
||||
2. 输入板块名称
|
||||
3. 点击"查询"
|
||||
4. 查看龙头股排名
|
||||
|
||||
**指标说明**：
|
||||
- **现价**：最新收盘价
|
||||
- **涨跌幅**：当日涨跌幅
|
||||
- **5日涨幅**：短期表现
|
||||
- **20日涨幅**：中期表现
|
||||
- **成交额**：日均成交金额（流动性指标）
|
||||
- **量比**：当日成交量 / 近20日均量
|
||||
|
||||
**投资策略**：
|
||||
```
|
||||
强者恒强：优先配置排名前3的龙头股
|
||||
分散持仓：龙头 + 二线股组合，平衡收益和风险
|
||||
轮动操作：龙头股涨幅过大时，切换到涨幅较小的潜力股
|
||||
```
|
||||
|
||||
**注意事项**：
|
||||
- 当前基于名称关键词匹配，可能不完全准确
|
||||
- 实际应用建议建立股票-板块映射表
|
||||
- 龙头股不等于买入信号，需结合技术面和估值
|
||||

|
||||
|
||||
### 5. 板块联动性分析
|
||||
|
||||
**功能说明**：
|
||||
通过相关系数热力图，分析板块之间的联动关系。
|
||||
|
||||
**使用场景**：
|
||||
- 发现高度相关的板块对
|
||||
- 分散投资时避免同涨同跌的板块
|
||||
- 识别产业链上下游关联
|
||||
|
||||
**相关系数解读**：
|
||||
|
||||
| 相关系数 | 含义 | 投资启示 |
|
||||
|----------|------|----------|
|
||||
| 0.9 - 1.0 | 极强正相关 | 几乎同涨同跌，分散效果差 |
|
||||
| 0.7 - 0.9 | 强正相关 | 联动性强，可能有产业链关系 |
|
||||
| 0.3 - 0.7 | 中度正相关 | 有一定联动性 |
|
||||
| -0.3 - 0.3 | 弱相关 | 独立性较强，分散效果好 |
|
||||
| -0.7 - -0.3 | 中度负相关 | 此消彼长 |
|
||||
| < -0.7 | 强负相关 | 跷跷板效应 |
|
||||
|
||||
**操作步骤**：
|
||||
1. 进入"板块分析" → "联动性"
|
||||
2. 查看热力图（红色=正相关，绿色=负相关）
|
||||
3. 查看高度相关板块对列表
|
||||
|
||||
**投资应用**：
|
||||
|
||||
**案例1：分散投资**
|
||||
```
|
||||
如果持有"半导体"板块，
|
||||
查询发现"半导体"与"新能源"相关系数 0.85（强相关），
|
||||
则不宜同时重仓这两个板块，
|
||||
应选择相关系数 < 0.5 的板块进行分散。
|
||||
```
|
||||
|
||||
**案例2：产业链联动**
|
||||
```
|
||||
发现"新能源汽车"与"锂电池"相关系数 0.92，
|
||||
说明产业链联动性强，
|
||||
当新能源汽车板块启动时，锂电池板块往往也会上涨。
|
||||
```
|
||||
|
||||
**案例3：风格轮动**
|
||||
```
|
||||
发现"科技成长"与"银行地产"相关系数 -0.6（负相关），
|
||||
说明市场风格在两者间切换，
|
||||
当科技股回调时，可关注银行地产的反弹机会。
|
||||
```

---
|
||||
|
||||
## 实战策略
|
||||
|
||||
### 策略1：板块轮动捕捉法
|
||||
|
||||
**步骤**：
|
||||
1. 每日查看"强弱趋势"，识别近5日涨幅前5的板块
|
||||
2. 进入"生命周期"，确认板块处于启动期或加速期
|
||||
3. 查看"龙头股"，选择涨幅和成交额靠前的2-3只
|
||||
4. 观察"资金流向"，确认有资金持续流入
|
||||
5. 买入并设置止盈（如+15%）和止损（如-5%）
|
||||
|
||||
**适用市场**：
|
||||
强势市场、板块轮动明显时
|
||||
|
||||
---
|
||||
|
||||
### 策略2：衰退期预警法
|
||||
|
||||
**步骤**：
|
||||
1. 持仓板块每周检查一次生命周期
|
||||
2. 若进入"衰退期"，逐步减仓50%
|
||||
3. 若5日涨幅转负，清仓离场
|
||||
4. 资金切换到处于"启动期"的新板块
|
||||
|
||||
**适用场景**：
|
||||
板块行情见顶，及时止盈
|
||||
|
||||
---
|
||||
|
||||
### 策略3：联动对冲法
|
||||
|
||||
**步骤**：
|
||||
1. 查看"联动性"，找出强负相关的板块对
|
||||
2. 同时配置两个板块，降低组合波动
|
||||
3. 如：科技（60%） + 银行（40%）
|
||||
4. 当一个板块回调时，另一个可能上涨
|
||||
|
||||
**适用场景**：
|
||||
震荡市、追求稳健收益
|
||||
|
||||
---
|
||||
|
||||
## 注意事项
|
||||
|
||||
1. **数据依赖**：
|
||||
- 需要先在"数据中台"入库板块和资金流数据
|
||||
- 建议每日收盘后执行一次入库
|
||||
|
||||
2. **板块分类**：
|
||||
- 当前使用 AkShare 的板块分类
|
||||
- 不同数据源的板块分类可能不同
|
||||
|
||||
3. **龙头股识别**：
|
||||
- 目前基于名称关键词匹配
|
||||
- 实际生产环境建议建立股票-板块映射表
|
||||
|
||||
4. **相关性稳定性**：
|
||||
- 相关系数会随市场环境变化
|
||||
- 建议定期（如每月）重新计算
|
||||
|
||||
5. **风险提示**：
|
||||
- 板块轮动分析是辅助工具，不构成投资建议
|
||||
- 需结合基本面、技术面综合判断
|
||||
- 设置止损，控制风险

|
||||
|
||||
## 数据表结构
|
||||
|
||||
### intraday_events
|
||||
```sql
|
||||
id SERIAL PRIMARY KEY
|
||||
code VARCHAR(12) -- 股票代码
|
||||

|
||||
```
|
||||
|
||||
## 推送配置
|
||||
|
||||
在 `backend/.env` 中配置以下任一渠道：
|
||||
|
||||
```env
|
||||
# SMTP 邮件
|
||||
SMTP_HOST=smtp.example.com
|
||||
SMTP_PORT=465
|
||||

|
||||
```
|
||||
|
||||
## 注意事项
|
||||
|
||||
1. **数据依赖**：
|
||||
- 需要先执行"数据中台"的入库操作
|
||||
- stock_metrics 表需有最新数据
|
||||
- 连板检测依赖历史日线数据
|
||||
|
||||
2. **性能优化**：
|
||||
- 使用5分钟 TTL 缓存避免重复推送
|
||||
- 非交易时间自动跳过检测
|
||||
|
||||
3. **扩展方向**：
|
||||
- 接入分钟线数据源提升检测精度
|
||||
- 添加自定义监控规则
|
||||
- 增加异动回测功能
|
||||
|
||||
## 后续优化计划
|
||||
|
||||
- [ ] 支持用户自定义监控条件
|
||||
- [ ] 异动发生后的历史表现统计
|
||||
- [ ] 结合AI分析给出操作建议
|
||||
- [ ] 移动端推送优化

# 社区情绪监控使用说明
|
||||
|
||||
## 功能概述
|
||||
|
||||
社区情绪监控模块通过爬取和分析东方财富、雪球等社区的热帖，量化散户情绪，提供反向投资指标。
|
||||
|
||||
**核心理念**：散户情绪往往是反向指标，当市场情绪极度乐观时可能是顶部，极度悲观时可能是底部。
|
||||
|
||||

|
||||
|
||||
## 五大核心功能
|
||||
|
||||
### 1. 情绪指数
|
||||
|
||||
**功能说明**：
|
||||
统计社区帖子的情绪倾向（乐观/悲观/中性），计算情绪指数。
|
||||
|
||||
**情绪分类**：
|
||||
|
||||
| 情绪 | 关键词示例 | 判断逻辑 |
|
||||
|------|------------|----------|
|
||||
| **乐观（Bullish）** | 看多、买入、突破、暴涨、牛市 | 包含2个及以上乐观关键词 |
|
||||
| **悲观（Bearish）** | 看空、卖出、下跌、暴跌、熊市 | 包含2个及以上悲观关键词 |
|
||||
| **中性（Neutral）** | 其他 | 情绪关键词不明显 |
|
||||
|
||||
**情绪指数定义**：
|
||||
```
|
||||
乐观比例 = 乐观帖子数 / 总帖子数 × 100%
|
||||
```
|
||||
|
||||
**反向指标解读**：
|
||||
|
||||
| 乐观比例 | 市场状态 | 投资建议 |
|
||||
|----------|----------|----------|
|
||||
| **≥ 80%** | 极度乐观 | ⚠️ 警惕顶部，考虑减仓 |
|
||||
| **60-80%** | 偏乐观 | 谨慎操作，不追高 |
|
||||
| **40-60%** | 中性 | 正常波动 |
|
||||
| **20-40%** | 偏悲观 | 关注机会，可适当建仓 |
|
||||
| **< 20%** | 极度悲观 | ✅ 可能是底部，积极布局 |
|
||||
|
||||
**使用步骤**：
|
||||
1. 进入"社区情绪" → "情绪指数"
|
||||
2. 点击"采集数据"（爬取最新帖子）
|
||||
3. 点击"计算指数"
|
||||
4. 查看乐观比例和历史趋势
|
||||
|
||||
**实战案例**：
|
||||
```
|
||||
案例1：2021年2月（牛市顶部）
|
||||
乐观比例：92%
|
||||
市场状态：极度乐观，到处都是"牛市来了""万点不是梦"
|
||||
实际走势：随后进入长达一年的调整
|
||||
|
||||
案例2：2022年10月（熊市底部）
|
||||
乐观比例：18%
|
||||
市场状态：极度悲观，"A股药丸""永不回本"
|
||||
实际走势：随后开启反弹
|
||||
```
|
||||
|
||||

|
||||
|
||||
### 2. 热议股票排行
|
||||
|
||||
**功能说明**：
|
||||
统计最近N天讨论量最高的股票，识别市场热点。
|
||||
|
||||
**热度评分公式**：
|
||||
```
|
||||
热度 = 帖子数 × 10 + 评论数
|
||||
```
|
||||
|
||||
**讨论量激增预警**：
|
||||
|
||||
当某只股票的讨论量突然激增，往往意味着：
|
||||
|
||||
✅ **正面信号**（早期）：
|
||||
- 新热点启动
|
||||
- 基本面改善引发关注
|
||||
- 可能是买入机会
|
||||
|
||||
⚠️ **负面信号**（后期）：
|
||||
- 追高情绪蔓延
|
||||
- 可能接近短期顶部
|
||||
- 谨慎追高
|
||||
|
||||
**使用技巧**：
|
||||
|
||||
**技巧1：结合股价走势**
|
||||
```
|
||||
如果热议股票尚未大涨（涨幅 < 10%）：
|
||||
→ 可能是早期机会，值得关注
|
||||
|
||||
如果热议股票已经暴涨（涨幅 > 30%）：
|
||||
→ 可能是追高情绪，谨慎介入
|
||||
```
|
||||
|
||||
**技巧2：观察持续性**
|
||||
```
|
||||
连续3天以上热议 + 股价稳步上涨：
|
||||
→ 趋势较强，可跟踪
|
||||
|
||||
突然冲上热议榜 + 股价暴涨：
|
||||
→ 情绪性炒作，风险较高
|
||||
```

- RSI < 70（未超买）
|
||||
- 量比 > 1.5（放量）
|
||||
|
||||
**卖出条件**（满足任一）：
|
||||

||||
|
||||
优于行业指标：4/5
|
||||
综合结论：优于行业
|
||||
|
||||
解读：茅台在盈利能力、成长性方面显著优于行业，是白酒板块的绝对龙头。
|
||||
```
|
||||
|
||||
**使用技巧**：
|
||||
1. 先看综合结论
|
||||
2. 重点关注优于/弱于的具体指标
|

高优先级优化
|
||||
1. 缓存与性能优化
|
||||
akshare_service.py 使用内存缓存,服务重启后失效。建议引入 Redis 持久化缓存,避免频繁调用 AkShare API
|
||||
大量接口未做分页,如 /api/trades、/api/alerts/events 在数据量大时会有性能问题
|
||||
K线数据查询未添加索引优化提示
|
||||
2. 错误处理与容错
|
||||
多数接口缺少统一的异常捕获,数据源异常时可能返回 500 错误
|
||||
scheduler.py 定时任务失败后缺少重试机制和告警
|
||||
AkShare 数据源不稳定时,降级逻辑不够完善(只有 mock 数据)
|
||||
3. 数据完整性
|
||||
交易记录(trades)无事务一致性保证,买卖不匹配时持仓计算可能出错
|
||||
缺少数据修正接口,入库错误数据后无法手动修正
|
||||
历史数据回填(ingest_all)无断点续传,中断后需重新开始
|
||||
4. 安全性
|
||||
所有接口无鉴权,任何人可访问管理功能(/api/admin/*)
|
||||
环境变量敏感信息(LLM_API_KEY等)未加密存储
|
||||
CORS 配置为 allow_origins=["*"],生产环境不安全
|
||||
中优先级优化
|
||||
5. 功能增强
|
||||
AI 诊断结果无历史记录,无法追溯分析质量变化
|
||||
预警系统只支持价格/涨跌幅,缺少技术指标预警(如 MACD 金叉、RSI 超买等)
|
||||
复盘日报只能手动触发推送,未自动推送给用户
|
||||
自选股只支持单一列表,无分组管理功能
|
||||
6. 代码质量
|
||||
main.py 超过 500 行,建议拆分为多个 Router 模块
|
||||
缺少单元测试和集成测试
|
||||
部分函数职责不清晰,如 _gen_review_text() 混合了业务逻辑和文案生成
|
||||
7. 监控与日志
|
||||
缺少接口访问日志和性能监控
|
||||
定时任务执行日志只保留在数据库,无实时监控面板
|
||||
AkShare 调用频率无监控,可能触发限流
|
||||
低优先级优化
|
||||
8. 用户体验
|
||||
前端刷新后丢失自选股筛选条件
|
||||
K线图无技术指标叠加功能(如 MACD、KDJ)
|
||||
移动端适配不足
|
||||
9. 扩展性
|
||||
只支持 A 股,缺少港股、美股扩展能力
|
||||
数据源绑定 AkShare,切换成本高
|
||||
多组合管理需要大幅重构 portfolio.py
|
||||
建议优先实现的 3 个功能
|
||||
Redis 缓存层 - 提升响应速度,减少 API 调用
|
||||
统一异常处理中间件 - 提升系统稳定性
|
||||
基础鉴权机制 - 保护管理接口安全
|
||||
需要我深入分析某个模块的优化方案吗?
