# A股交易信号回测/策略验证
## 数据源
```bash
SCRIPTS="$SKILLS_ROOT/cn-stock-data/scripts"
python "$SCRIPTS/cn_stock_data.py" kline --code [CODE] --freq daily --start [日期]
python "$SCRIPTS/cn_stock_data.py" quote --code [CODE]
python "$SCRIPTS/cn_stock_data.py" finance --code [CODE]
```
## Workflow
### Step 1: 定义交易信号
明确入场/出场条件
### Step 2: 获取历史K线
### Step 3: 生成信号序列
标记每个交易日的信号(买入/卖出/持有)
### Step 4: 回测绩效
- 胜率、盈亏比、最大回撤
- 年化收益率、夏普比率
- 信号频率、平均持有期
### Step 5: 输出
| 维度 | formal | brief |
|------|--------|-------|
| 绩效 | 完整回测报告 | 胜率+夏普 |
| 交易明细 | 每笔交易记录 | 统计摘要 |
| 稳健性 | 分年度/参数敏感性 | 是否稳健 |
默认风格:brief。
## 关键规则
1. 回测不代表未来——过拟合是最大风险
2. 样本外验证至关重要——至少留20%数据
3. 考虑交易成本(A股约0.15%单边)和滑点
4. T+1限制需在回测中体现——当日信号次日执行
5. 参数敏感性分析:参数微调后收益不应剧变
## 使用示例
### 示例 1: 基本使用
```python
# 调用 skill
result = run_skill({
"param1": "value1",
"param2": "value2"
})
```
### 示例 2: 命令行使用
```bash
python scripts/run_skill.py --input data.json
```

Playbook for creating and editing uCoz landing pages via MCP tools (`templates_tool`, `ftp_tool`, `modules_tool`). Use for tasks such as: "build a landing page", "update the homepage as a landing page", "create a promo page on the homepage", "add a lead form / menu / SEO to the homepage". Homepage: `page_list`, `page_get`; first publish — `page_update` with full `page_tmpl`; HTML edits after generation — `patch_template` (module_id=2, template_id=1), not `update_template`.
