# 历史选股代码规格
|
||||||
|
|
||||||
|
## Scenario: `zhixing_b1` 历史公式评估
|
||||||
|
|
||||||
|
### 1. Scope / Trigger
|
||||||
|
|
||||||
|
- 触发：新增 `modules/selection` bounded context，基于 PostgreSQL 已保存的 qfq
|
||||||
|
日线执行历史知行 B1 公式。
|
||||||
|
- 边界：selection 只读市场事实并返回领域评估结果；不负责市场数据同步、信号
|
||||||
|
持久化、批次调度、HTTP 路由或前端展示。
|
||||||
|
|
||||||
|
### 2. Signatures
|
||||||
|
|
||||||
|
- `MarketDataReader.load_history(ts_code: str, target_trade_date: date) -> StockHistory`
|
||||||
|
- `ZhixingB1Strategy.evaluate(history: StockHistory, target_trade_date: date) -> SelectionEvaluation`
|
||||||
|
- `EvaluateZhixingB1.execute(ts_code: str, target_trade_date: date) -> SelectionEvaluation`
|
||||||
|
- `SelectionSignal.identity -> tuple[str, date, str, str]`
|
||||||
|
|
||||||
|
### 3. Contracts
|
||||||
|
|
||||||
|
- `StockHistory.bars` 必须是升序、去重的 qfq 行情，且不得包含目标交易日之后的
|
||||||
|
数据；`daily_basic` 按交易日保存同日可空指标。
|
||||||
|
- `SelectionBar` 使用有限的 `float | None` 表示 OHLCV；目标日的 open/high/low/
|
||||||
|
close/volume 任一缺失时不得生成信号。
|
||||||
|
- 策略名称固定为 `zhixing_b1`；7 个分类固定为
|
||||||
|
`zhixing_b1_oversold_turn`、`zhixing_b1_oversold_volume`、
|
||||||
|
`zhixing_b1_original_b1`、`zhixing_b1_extreme_volume`、
|
||||||
|
`zhixing_b1_pullback_white`、`zhixing_b1_pullback_super`、
|
||||||
|
`zhixing_b1_pullback_yellow`。
|
||||||
|
- 同一股票同一交易日可以返回多个分类；唯一身份是
|
||||||
|
`(ts_code, target_trade_date, strategy, category)`，返回顺序遵循
|
||||||
|
`ZHIXING_B1_SIGNAL_ORDER`。
|
||||||
|
- PostgreSQL reader 必须参数化查询 `source_adj = 'qfq'` 且
|
||||||
|
`trade_date <= target_trade_date`，左连接同日 `market_daily_basic`；不得回退到
|
||||||
|
CSV、Tushare 或当前最后一行。
|
||||||
|
- 评估状态区分 `selected`、`no_signal`、`insufficient_history`、
|
||||||
|
`missing_target_bar` 和 `data_error`。业务状态不是异常，数据库读取失败才映射为
|
||||||
|
`data_error`。
|
||||||
|
|
||||||
|
### 4. Validation & Error Matrix
|
||||||
|
|
||||||
|
| 条件 | 行为 |
|
||||||
|
| --- | --- |
|
||||||
|
| 少于公式最小暖机长度 | 返回 `insufficient_history`，不返回信号 |
|
||||||
|
| 目标日没有 qfq bar 或 OHLCV 不完整 | 返回 `missing_target_bar` |
|
||||||
|
| 目标日数据完整但无分类命中 | 返回 `no_signal` |
|
||||||
|
| PostgreSQL 读取失败 | 返回 `data_error`，保留股票和目标日上下文 |
|
||||||
|
| rolling 窗口不足 | 只使用已到达的交易行；`EVERY` 等需要完整窗口的条件不命中 |
|
||||||
|
| 除零、NaN 或无穷中间值 | 转为 NaN/False，不得静默制造命中 |
|
||||||
|
|
||||||
|
### 5. Good / Base / Bad Cases
|
||||||
|
|
||||||
|
- Good：给定历史目标日，reader 只返回该日及之前的 qfq 行，策略返回可序列化详情
|
||||||
|
和全部命中分类。
|
||||||
|
- Base：同日多分类命中时每类都保留稳定身份；同日 `daily_basic` 缺失只影响实际
|
||||||
|
依赖该指标的条件。
|
||||||
|
- Bad：用当前最新市值覆盖历史 K 线、取 bars 最后一行代替显式目标日，或把 7 类
|
||||||
|
mask OR 成一个结果后丢失分类。
|
||||||
|
|
||||||
|
### 6. Tests Required
|
||||||
|
|
||||||
|
- 指标单元测试：rolling 暖机、交易日 `REF`、窗口边界、除零、NaN、宽幅代码参数。
|
||||||
|
- 策略单元测试：目标日截断、暖机/缺失状态、7 个 mask 独立存在和同日多分类身份。
|
||||||
|
- reader 单元测试：参数化 SQL、qfq 过滤、目标日截断、升序映射和 left join 可空值。
|
||||||
|
- golden 测试：离线固定 fixture 可重复运行；不得在测试运行时导入旧项目或访问生产库。
|
||||||
|
|
||||||
|
### 7. Wrong vs Correct
|
||||||
|
|
||||||
|
#### Wrong
|
||||||
|
|
||||||
|
```python
|
||||||

target = history.bars[-1]
|
||||||
|
first = next(category for category in categories if masks[category].iloc[-1])
|
||||||
|
```
|
||||||
|
|
||||||
|
#### Correct
|
||||||
|
|
||||||
|
```python
|
||||||
|
# 用显式交易日定位，并保留所有独立 mask 的命中。
|
||||||
|
target_index = frame.index[frame["trade_date"] == target_trade_date][0]

# 知行 B1 选股策略迁移设计
|
||||||
|
|
||||||
|
## 1. 设计目标
|
||||||
|
|
||||||
|
在新项目中建立 `selection` bounded context，完成 `zhixing_b1` 的第一条公式级
|
||||||
|
垂直切片：策略可以接收明确的目标交易日和历史行情，按通达信公式计算 7 个
|
||||||
|
子信号，并返回可解释、可重复、可区分的多分类信号结果。
|
||||||
|
|
||||||
|
本任务不创建信号数据库表、HTTP API、前端页面或全市场批次调度。信号模型先
|
||||||
|
提供稳定身份和后续持久化所需的契约。
|
||||||
|
|
||||||
|
## 2. 上下文与依赖方向
|
||||||
|
|
||||||
|
新增目录：
|
||||||
|
|
||||||
|
```text
|
||||||
|
zhixing-server/src/zhixing_server/modules/selection/
|
||||||
|
├── domain/
|
||||||
|
│ ├── models.py # 行情输入、策略信号、评估结果
|
||||||
|
│ ├── ports.py # 市场历史读取端口

||||||
|
│ ├── indicators.py # TDX 风格滚动/递推指标原语
|
||||||
|
│ ├── zhixing_b1.py # 知行 B1 公式及 7 个子信号
|
||||||
|
│ └── __init__.py
|
||||||
|
├── application/

||||||
|
│ └── __init__.py
|
||||||
|
└── presentation/
|
||||||
|
└── __init__.py
|
||||||
|
```
|
||||||
|
|
||||||
|
- `selection.domain` 不导入 FastAPI、Psycopg 或 PostgreSQL 适配器。
|
||||||
|
- `selection.domain.ports` 定义策略需要的最小 `MarketDataReader`，不复用旧项目
|
||||||
|
的 CSV repository，也不让策略直接拼 SQL。
|
||||||
|
- `selection.infrastructure.postgres_reader` 只读 `market_stock`、
|
||||||
|
`market_daily_bar` 和 `market_daily_basic`；市场数据写入仍归 `market_data`
|
||||||
|
bounded context 所有。
|
||||||
|
- `selection.application` 负责把目标代码、目标交易日交给 reader 和纯领域策略，
|
||||||
|
将数据缺失、无信号和基础设施错误区分开。
|
||||||
|
- 暂不把 `selection` 接入顶层 HTTP router 或 FastAPI 应用组合，避免首期引入
|
||||||
|
未确定的产品 API 契约。
|
||||||
|
|
||||||
|
## 3. 领域模型
|
||||||
|
|
||||||
|
### 3.1 输入模型
|
||||||
|
|
||||||
|
定义面向策略的只读分析模型，不把 PostgreSQL 的 `Decimal`、Tushare 字段名或
|
||||||
|
Pandas DataFrame 暴露给应用调用方：
|
||||||
|
|
||||||
|
- `SelectionBar`：`trade_date`、`open`、`high`、`low`、`close`、`volume`，价格
|
||||||
|
和成交量在适配器边界转换为与旧项目一致的有限 `float`。
|
||||||
|
- `SelectionDailyBasic`：`trade_date`、可选 `turnover_rate`、`total_mv` 等策略
|
||||||
|
可能使用的同日指标。
|
||||||
|
- `StockHistory`：股票代码、名称、升序 bars、按日期索引的 daily basic；只包含
|
||||||
|
`trade_date <= target_trade_date` 的记录。
|
||||||
|
|
||||||
|
`MarketDataReader.load_history(ts_code, target_trade_date)` 必须保证：
|
||||||
|
|
||||||
|
1. bars 按交易日升序、去重，且只来自 `source_adj = 'qfq'`；
|
||||||
|
2. 不把目标日之后的数据泄露给策略；
|
||||||
|
3. 返回足够的历史 warm-up。首期直接返回数据库保留窗口内截至目标日的全部可用
|
||||||
|
行情，避免人为截断导致 EMA/KDJ 与旧实现不一致；
|
||||||
|
4. 目标日没有有效 bar 时返回可识别的缺失状态，而不是把更早日期伪装成目标日；
|
||||||
|
5. 同日 `daily_basic` 缺失保留为可观察的缺失值，只有公式实际需要的字段才影响
|
||||||
|
可选条件。
|
||||||
|
|
||||||
|
### 3.2 信号模型
|
||||||
|
|
||||||
|
定义 `ZhixingB1Category` 的 7 个稳定语义分类，外部值不再使用旧的
|
||||||
|
`xg_composite` 前缀：
|
||||||
|
|
||||||
|
- `zhixing_b1_oversold_turn`
|
||||||
|
- `zhixing_b1_oversold_volume`
|
||||||
|
- `zhixing_b1_original_b1`
|
||||||
|
- `zhixing_b1_extreme_volume`
|
||||||
|
- `zhixing_b1_pullback_white`
|
||||||
|
- `zhixing_b1_pullback_super`
|
||||||
|
- `zhixing_b1_pullback_yellow`
|
||||||
|
|
||||||
|
`SelectionSignal` 至少包含：
|
||||||
|
|
||||||
|
- `ts_code`、`name`、`target_trade_date`；
|
||||||
|
- `strategy = "zhixing_b1"`；
|
||||||
|
- 一个 `ZhixingB1Category`；
|
||||||
|
- qfq `close`；
|
||||||
|
- 可序列化的关键详情，如 J、RSI、知行白线/黄线、振幅、成交量比和命中的
|
||||||
|
公式标签。
|
||||||
|
|
||||||
|
稳定身份为 `(ts_code, target_trade_date, strategy, category)`。同一行数据可以
|
||||||
|
产生多个 category，返回顺序固定为公式文件中 7 个子信号的优先级顺序。
|
||||||
|
|
||||||
|
### 3.3 评估结果
|
||||||
|
|
||||||
|
用例返回带状态的 `SelectionEvaluation`，至少区分：
|
||||||
|
|
||||||
|
- `selected`：至少一个子信号命中；
|
||||||
|
- `no_signal`：目标日数据完整但没有子信号命中；
|
||||||
|
- `insufficient_history`：少于公式要求的最小暖机长度；
|
||||||
|
- `missing_target_bar`：目标交易日没有 qfq 日线；
|
||||||
|
- `data_error`：市场数据适配器发生不可恢复的读取错误。
|
||||||
|
|
||||||
|
`no_signal`、`insufficient_history` 和 `missing_target_bar` 不是异常；数据库连接
|
||||||
|
或 SQL 失败才转换为带上下文的基础设施错误。
|
||||||
|
|
||||||
|
## 4. 公式实现策略
|
||||||
|
|
||||||
|
### 4.1 计算层
|
||||||
|
|
||||||
|
为保持与旧实现及通达信公式的数值语义一致，首期使用直接依赖的 Pandas/NumPy
|
||||||
|
实现向量化指标。当前 `tushare` 已将 Pandas/NumPy 带入锁文件，但新代码直接
|
||||||
|
使用它们，因此实施阶段将把 `pandas` 和 `numpy` 声明为后端直接依赖并更新
|
||||||
|
`uv.lock`。
|
||||||
|
|
||||||
|
在 `selection.domain.indicators` 内实现或迁移以下原语，并用纯输入测试锁定边界：
|
||||||
|
|
||||||
|
- `MA`、`EMA`、`LLV`、`HHV`、`SMA`、`REF`；
|
||||||
|
- `EXIST`、`EVERY`、`COUNT`、`HHVBARS`、`BARSLAST`、`CROSS`；
|
||||||
|
- TDX 风格 KDJ、RSI、知行白线/黄线；
|
||||||
|
- 板块宽幅判定及振幅区间/放宽系数；
|
||||||
|
- 大绿棒、缩量、异动、趋势、回踩和 BBI 派生条件。
|
||||||
|
|
||||||
|
旧项目的 `prepare_xg_indicators()` 可以作为迁移起点，但不得原样保留对旧项目
|
||||||
|
`SignalCategory`、`zgnb` 包或旧 CSV 字段的导入。所有跨公式共享原语先归入
|
||||||
|
`selection` 上下文，等第二个策略迁移时再根据真实复用情况决定是否上移到
|
||||||
|
`shared`。
|
||||||
|
|
||||||
|
### 4.2 7 个子信号
|
||||||
|
|
||||||
|
将旧实现的 7 个 mask 逐一迁移为命名清晰的领域计算步骤，计算结果保留每个
|
||||||
|
mask，而不是先 OR 成单一 `_存在B` 后只取第一项。最终组合逻辑为：
|
||||||
|
|
||||||
|
```text
|
||||||
|
all_matches = [category for category in priority_order if category.mask(target_row)]
|
||||||
|
```
|
||||||
|
|
||||||
|
每个 mask 必须与通达信公式逐段对照；旧实现已经存在的 v1203 调整（例如上涨
|
||||||
|
十字星的涨幅限制、原始 B1 的放宽缩量分支）作为有意语义保留，并在测试名或
|
||||||
|
fixture 说明中标明。
|
||||||
|
|
||||||
|
### 4.3 缺失值和暖机
|
||||||
|
|
||||||
|
- 公式所需 rolling 窗口不足时遵循旧实现的窗口语义，不用当前行的未来数据补齐。
|
||||||
|
- 目标日需要的 OHLCV 缺失时不生成信号。
|
||||||
|
- 中间指标出现 NaN 时，比较型条件默认不命中；除零场景显式转为 NaN/False，
|
||||||
|
不让异常被静默吞掉。
|
||||||
|
- 不使用 `except Exception` 将单个子信号错误转成全局无信号；公式实现错误应
|
||||||
|
让测试或应用调用失败可见。
|
||||||
|
|
||||||
|
## 5. PostgreSQL 只读适配器
|
||||||
|
|
||||||
|
`PostgresMarketDataReader` 使用现有 `Settings.database_url`，通过参数化 SQL
|
||||||
|
读取：
|
||||||
|
|
||||||
|
```sql
|
||||||
|
SELECT
|
||||||
|
bar.ts_code, bar.trade_date, bar.open, bar.high, bar.low, bar.close,
|
||||||
|
bar.vol, basic.turnover_rate, basic.total_mv
|
||||||
|
FROM market_daily_bar AS bar
|
||||||
|
LEFT JOIN market_daily_basic AS basic
|
||||||
|
ON basic.ts_code = bar.ts_code
|
||||||
|
AND basic.trade_date = bar.trade_date
|
||||||
|
WHERE bar.ts_code = %s
|
||||||
|
AND bar.source_adj = 'qfq'
|
||||||
|
AND bar.trade_date <= %s
|
||||||
|
ORDER BY bar.trade_date
|
||||||
|
```
|
||||||
|
|
||||||
|
适配器只负责查询、字段映射、排序和缺失状态；不写数据库、不回退到 CSV、不
|
||||||
|
调用 Tushare。查询整个六年保留窗口是首期的正确性优先选择，后续全市场运行
|
||||||
|
若证明有性能压力再引入可配置 warm-up 窗口和批量读取。
|
||||||
|
|
||||||
|
## 6. 验证策略
|
||||||
|
|
||||||
|
### 6.1 公式单元测试
|
||||||
|
|
||||||
|
为每个原语和 7 个 mask 提供边界案例，至少包含：
|
||||||
|
|
||||||
|
- rolling 窗口刚好不足、刚好满足和超过；
|
||||||
|
- `high == low`、前收为零、成交量为零、NaN/None；
|
||||||
|
- 30/68/普通代码的幅度参数；
|
||||||
|
- 大绿棒在 15 日前/后、当前最大量切换；
|
||||||
|
- 上涨十字星涨幅小于 4% 与超过 4%；
|
||||||
|
- 同一行同时满足多个 mask。
|
||||||
|
|
||||||
|
### 6.2 历史 golden
|
||||||
|
|
||||||
|
从旧项目现有 `data/raw` 中选择少量公开行情样本，抽取为新项目测试 fixture，
|
||||||
|
不让测试运行时依赖旧项目目录。固定 fixture 包含：
|
||||||
|
|
||||||
|
- 升序 qfq OHLCV CSV；
|
||||||
|
- 目标交易日和股票代码；
|
||||||
|
- 旧实现/人工确认的命中分类集合；
|
||||||
|
- 关键详情允许小数误差的期望值。
|
||||||
|
|
||||||
|
golden 只验证固定样本，不把旧实现当成新实现的运行时依赖。对于旧实现当前
|
||||||
|
只保留第一个子信号的行为，golden 记录“新实现返回全部命中分类”的有意差异。
|
||||||
|
|
||||||
|
### 6.3 端口和适配器测试
|
||||||
|
|
||||||
|
- Fake reader 测试应用用例只传入目标日前数据，并区分无信号、目标日缺失和
|
||||||
|
基础设施错误。
|
||||||
|
- PostgreSQL reader 使用 mock/fake connection 验证参数化查询、qfq 过滤、升序
|
||||||
|
映射和基本指标左连接；不访问真实网络。
|
||||||
|
- 如使用 PostgreSQL 集成测试，沿用 `ZHIXING_TEST_DATABASE_URL` marker，且
|
||||||
|
不把它作为普通单测必需条件。
|
||||||
|
|
||||||
|
## 7. 兼容性、回滚与后续演进
|
||||||
|
|
||||||
|
- 不修改旧项目目录和旧 SQLite 数据；迁移结果通过 `zhixing_b1` 新身份区分。
|
||||||
|
- 首期不创建数据库迁移，因此回滚只需移除新 selection 模块和直接依赖，不影响
|
||||||
|
已有 market-data 表及同步任务。
|
||||||
|
- 后续增加策略时，优先复用真实验证后确认的 `selection.domain.indicators`；
|
||||||
|
不预先建立跨上下文的全局指标工具箱。
|
||||||
|
- 后续实现信号持久化时，可直接使用稳定身份 `(ts_code, date, strategy,
|
||||||
|
category)` 建立唯一键；本任务不提前锁定表结构或 HTTP 字段。

# 知行 B1 选股策略实施计划
|
||||||
|
|
||||||
|
## 实施原则
|
||||||
|
|
||||||
|
- 只修改 `zhixing-system`；旧项目只读，不回写、不重命名、不提交旧项目数据。
|
||||||
|
- 先写行为测试，再补最小实现；每一步保持 `uv run pytest` 可定位失败范围。
|
||||||
|
- `zhixing_b1` 是新策略身份；不要把 `xg_composite` 作为新模块的对外名称。
|
||||||
|
- 公式语义优先于旧 Python 的偶然行为；每个有意差异都要在 fixture 或测试名中
|
||||||
|
留下证据。
|
||||||
|
- 不启动 HTTP、前端、信号持久化或全市场批次编排；它们属于后续任务。
|
||||||
|
|
||||||
|
## 1. 依赖与模块骨架
|
||||||
|
|
||||||
|
- 在 `zhixing-server/pyproject.toml` 声明直接依赖 `pandas` 和 `numpy`，执行
|
||||||
|
`uv lock`，确认锁文件与 Python 3.12 环境一致。
|
||||||
|
- 创建 `modules/selection/{domain,application,infrastructure,presentation}`
|
||||||
|
包和上下文 README，保持 domain 不导入 FastAPI/Psycopg。
|
||||||
|
- 先新增领域模型、端口和评估状态类型，再接入基础设施。
|
||||||
|
|
||||||
|
验证：
|
||||||
|
|
||||||
|
```bash
|
||||||
|
cd zhixing-server
|
||||||
|
uv lock --check
|
||||||
|
uv run python -c "import numpy, pandas; print(numpy.__version__, pandas.__version__)"
|
||||||
|
```
|
||||||
|
|
||||||
|
回滚点：依赖或包骨架若无法通过 Ruff/Pyright，先撤销骨架，不触碰
|
||||||
|
`modules/market_data`。
|
||||||
|
|
||||||
|
## 2. 迁移公式原语
|
||||||
|
|
||||||
|
- 从旧项目 `shared/indicators.py`、`kdj.py`、`rsi.py`、`zhixing.py` 和
|
||||||
|
`market_type.py` 提取必要实现到 `selection/domain/indicators.py`。
|
||||||
|
- 先覆盖 `MA/EMA/LLV/HHV/SMA/REF/EXIST/EVERY/COUNT/HHVBARS/BARSLAST/CROSS`，
|
||||||
|
再实现 KDJ、RSI、知行线和板块幅度参数。
|
||||||
|
- 每个公共函数增加完整类型、参数/返回值/边界说明；NaN、除零和不足窗口行为
|
||||||
|
用测试锁定。
|
||||||
|
- 不引入 Numba、SciPy 或其他旧项目专用依赖；首期 Pandas/NumPy 足够保持公式
|
||||||
|
计算的向量化和数值接近。
|
||||||
|
|
||||||
|
验证：
|
||||||
|
|
||||||
|
```bash
|
||||||
|
cd zhixing-server
|
||||||
|
uv run pytest tests/unit/selection/test_indicators.py
|
||||||
|
```
|
||||||
|
|
||||||
|
## 3. 实现 `ZhixingB1Strategy`
|
||||||
|
|
||||||
|
- 将旧 `prepare_xg_indicators()` 拆成可读的领域计算步骤：基础线、振幅、KDJ/RSI、
|
||||||
|
缩量、大绿棒、异动、趋势、距离/回踩、7 个子信号。
|
||||||
|
- 策略类固定 `name = "zhixing_b1"`，公开入口显式接收 `StockHistory` 和
|
||||||
|
`target_trade_date`。
|
||||||
|
- 对目标交易日定位使用日期索引，不使用 DataFrame 最后一行猜测目标日期。
|
||||||
|
- 保留 7 个 mask 的全部命中，按公式顺序产生多个 `SelectionSignal`，不可使用
|
||||||
|
旧代码中的 `break`。
|
||||||
|
- 详情只写可序列化、与目标行相关的关键指标；不要保存整张 DataFrame。
|
||||||
|
- 对目标日缺失、历史不足、无信号分别返回评估状态；公式计算异常向上暴露，
|
||||||
|
不静默转换为空结果。
|
||||||
|
|
||||||
|
验证：
|
||||||
|
|
||||||
|
```bash
|
||||||
|
cd zhixing-server
|
||||||
|
uv run pytest tests/unit/selection/test_zhixing_b1.py
|
||||||
|
```
|
||||||
|
|
||||||
|
回滚点：若结果数量明显偏离 golden，保留公式原语测试和差异报告，回滚策略
|
||||||
|
编排层，不回退到旧 `xg_composite` 命名。
|
||||||
|
|
||||||
|
## 4. 建立市场数据读取端口与 PostgreSQL 适配器
|
||||||
|
|
||||||
|
- 在 `selection/domain/ports.py` 定义只读 `MarketDataReader`。
|
||||||
|
- 在 `selection/infrastructure/postgres_reader.py` 实现参数化查询，读取 qfq
|
||||||
|
`market_daily_bar`，左连接同日 `market_daily_basic`，按日期升序映射为
|
||||||
|
`StockHistory`。
|
||||||
|
- 从 `Settings` 注入连接串；不直接读取环境变量，不调用 Tushare，不回退 CSV。
|
||||||
|
- 使用数据库事实表的 `source_adj = 'qfq'` 过滤，拒绝目标日之后的行。
|
||||||
|
- 连接失败转换为带股票和目标日上下文的基础设施错误；目标日无 bar 属于可识别
|
||||||
|
的业务状态。
|
||||||
|
|
||||||
|
验证：
|
||||||
|
|
||||||
|
```bash
|
||||||
|
cd zhixing-server
|
||||||
|
uv run pytest tests/unit/selection/test_postgres_reader.py
|
||||||
|
```
|
||||||
|
|
||||||
|
若增加 PostgreSQL 集成覆盖：
|
||||||
|
|
||||||
|
```bash
|
||||||
|
cd zhixing-server
|
||||||
|
uv run pytest -m integration tests/integration/test_selection_reader.py
|
||||||
|
```
|
||||||
|
|
||||||
|
回滚点：只读适配器失败时删除 selection 适配器即可；不得修改已有市场数据表、
|
||||||
|
同步事务或 Alembic migration。
|
||||||
|
|
||||||
|
## 5. 应用用例与 Fake reader
|
||||||
|
|
||||||
|
- 实现 `EvaluateZhixingB1`，输入 `ts_code`、`target_trade_date` 和 reader，输出
|
||||||
|
`SelectionEvaluation`。
|
||||||
|
- 用例只负责读取、调用领域策略和映射错误；不负责全市场循环、保存信号或 HTTP
|
||||||
|
响应。
|
||||||
|
- 提供 Fake reader 测试目标日期截断、缺失目标行、历史不足、无信号、选中多分类
|
||||||
|
和基础设施错误。
|
||||||
|
|
||||||
|
验证：
|
||||||
|
|
||||||
|
```bash
|
||||||
|
cd zhixing-server
|
||||||
|
uv run pytest tests/unit/selection/test_evaluate.py
|
||||||
|
```
|
||||||
|
|
||||||
|
## 6. 固定 fixture 与 golden 对比
|
||||||
|
|
||||||
|
- 从旧项目现有 `data/raw` 中选取少量股票和目标日期，抽取最小 OHLCV CSV，放入
|
||||||
|
`zhixing-server/tests/fixtures/selection/zhixing_b1/`。
|
||||||
|
- 将旧实现或人工确认结果固化为 JSON，包含目标日期、命中分类集合和关键详情的
|
||||||
|
容差范围；测试运行时不导入旧项目。
|
||||||
|
- 至少包含普通代码和宽幅代码，并加入一个人工构造的同日多信号样本。
|
||||||
|
- 明确记录旧实现“只保留第一个分类”与新实现“保留全部分类”的差异。
|
||||||
|
|
||||||
|
验证：
|
||||||
|
|
||||||
|
```bash
|
||||||
|
cd zhixing-server
|
||||||
|
uv run pytest tests/integration/test_zhixing_b1_golden.py
|
||||||
|
```
|
||||||
|
|
||||||
|
## 7. 完整质量检查与规划复核
|
||||||
|
|
||||||
|
实现结束后运行：
|
||||||
|
|
||||||
|
```bash
|
||||||
|
cd zhixing-server
|
||||||
|
uv run ruff format --check .
|
||||||
|
uv run ruff check .
|
||||||
|
uv run pyright
|
||||||
|
uv run pytest
|
||||||
|
```
|
||||||
|
|
||||||
|
并检查：
|
||||||
|
|
||||||
|
- `rg -n "xg_composite|zgnb\." src/zhixing_server/modules/selection tests` 只在
|
||||||
|
迁移说明或兼容性测试中出现，不成为新领域运行时依赖；
|
||||||
|
- 旧项目工作区没有被修改；
|
||||||
|
- 没有新增 HTTP 路由、前端文件、信号表 migration 或调度入口；
|
||||||
|
- golden、单元测试和端口测试都能在无网络、无生产数据库条件下运行。
|
||||||
|
|
||||||
|
完成 planning 后，先向用户展示 `prd.md`、`design.md` 和本文件摘要；只有用户
|
||||||
|
明确批准最新 planning summary，才能执行 `task.py start` 并进入实现阶段。

# 迁移知行B1选股策略
|
||||||
|
|
||||||
|
## Goal
|
||||||
|
|
||||||
|
在新项目中迁移旧项目的 `xg_composite` 选股逻辑，并将新策略名称统一为
|
||||||
|
`zhixing_b1`，让系统能够基于 PostgreSQL 中的历史市场数据执行可复现的知行
|
||||||
|
B1 选股。
|
||||||
|
|
||||||
|
首期采用“公式级垂直切片”：从通达信公式、指标计算、7 个子信号、信号结果、
|
||||||
|
市场数据读取到历史验证用例打通一条完整链路；不在本任务内铺开其他策略或完整
|
||||||
|
前端产品能力。
|
||||||
|
|
||||||
|
## Background and confirmed facts
|
||||||
|
|
||||||
|
- 旧项目的 `xg_composite` 对应通达信选股公式，包含 7 个子信号；实现位于
|
||||||
|
`zgnb-project/src/zgnb/domain/strategy/xg_composite.py`，公式原文位于
|
||||||
|
`zgnb-project/docs/references/formulas/tongdaxin_xuangu_formula.txt`。
|
||||||
|
- 旧项目的共享指标实现位于 `zgnb-project/src/zgnb/shared/xg_indicators.py`，
|
||||||
|
其中包含知行线、BBI、KDJ、RSI、振幅、趋势、回踩和 7 个子信号条件。
|
||||||
|
- 旧项目目前只返回第一个命中的 XG 子信号；本任务以公式/业务意图为准，允许
|
||||||
|
同一股票同一交易日产生多条不同分类的信号。
|
||||||
|
- 新项目已确定 PostgreSQL 为市场数据事实源、价格使用 qfq 日线、股票池为当前
|
||||||
|
沪深非 ST A 股，并保留 6 年数据窗口。
|
||||||
|
- 新项目当前已有 `market_daily_bar`、`market_daily_basic` 和市场数据领域端口，
|
||||||
|
但还没有策略读取端口、选股信号模型或策略 API。
|
||||||
|
|
||||||
|
## Requirements
|
||||||
|
|
||||||
|
### R1. 迁移策略身份
|
||||||
|
|
||||||
|
- 新策略的业务标识为 `zhixing_b1`。
|
||||||
|
- 领域逻辑不得继续依赖旧项目的 `xg_composite` 命名作为对外策略身份。
|
||||||
|
- 7 个子信号保留独立分类，并可在同一股票同一交易日同时出现。
|
||||||
|
|
||||||
|
### R2. 公式语义
|
||||||
|
|
||||||
|
- 以通达信公式和已确认的 v1203 业务调整为主要依据，旧 Python 实现作为迁移
|
||||||
|
参考和差异线索。
|
||||||
|
- 不复制旧流程中将最新市值写入全部历史 K 线、按当前日期查询历史 B1 信号等
|
||||||
|
不能支持历史重放的行为。
|
||||||
|
- 对公式中涉及的代码板块、涨跌幅放宽系数、振幅区间、缩量、大绿棒、趋势、
|
||||||
|
回踩和 7 个子信号条件建立可测试的实现。
|
||||||
|
|
||||||
|
### R3. 市场数据读取
|
||||||
|
|
||||||
|
- 策略使用市场数据领域端口读取目标交易日之前的足够 warm-up 日线数据。
|
||||||
|
- OHLCV 指标使用 `market_daily_bar` 的 qfq 价格与成交量；换手率等估值/交易
|
||||||
|
条件使用同一交易日的 `market_daily_basic` 快照。
|
||||||
|
- 策略计算不得直接依赖 PostgreSQL、Pandas SQL 查询或具体 HTTP 层实现。
|
||||||
|
- 历史选股必须显式使用 `target_trade_date`，不得隐式退化为“当前最后一行”。
|
||||||
|
|
||||||
|
### R4. 信号结果
|
||||||
|
|
||||||
|
- 信号至少包含股票、交易日、策略标识、子信号分类、收盘价和可解释的关键指标
|
||||||
|
详情。
|
||||||
|
- 信号提供由“股票、交易日、策略标识、子信号分类”组成的稳定身份；不同子信号
|
||||||
|
分类不得被合并丢失，为后续持久化提供幂等依据。
|
||||||
|
|
||||||
|
### R5. 验证
|
||||||
|
|
||||||
|
- 为共享指标和每个子信号建立边界条件测试，覆盖缺数据、暖机期、除零和板块
|
||||||
|
参数差异。
|
||||||
|
- 提供固定历史样本的策略级验证，能够判断新实现是否符合公式语义，并明确记录
|
||||||
|
与旧实现的有意差异。
|
||||||
|
- 验证不得访问真实 Tushare、生产数据库或依赖实时网络。
|
||||||
|
|
||||||
|
## Out of scope
|
||||||
|
|
||||||
|
- `bowl_rebound`、`b1`、`b1b2`、`brick_chart` 的迁移。
|
||||||
|
- 完整选股批次编排、自动调度、前端页面和图表生成。
|
||||||
|
- 选股信号 PostgreSQL 表、信号持久化实现和 HTTP API。
|
||||||
|
- 实盘交易、回测收益评价和策略参数优化。
|
||||||
|
- 为解决本任务而改变既有市场数据同步的股票池、qfq 或六年保留契约。
|
||||||
|
|
||||||
|
## Acceptance Criteria
|
||||||
|
|
||||||
|
- [ ] 新项目存在名为 `zhixing_b1` 的领域策略，并能在显式目标交易日上运行。
|
||||||
|
- [ ] 7 个子信号均有独立分类；同一股票同日多信号不会互相覆盖，并具有稳定身份。
|
||||||
|
- [ ] 策略只通过市场数据端口获得 qfq 日线和同日交易指标，不直接耦合存储实现。
|
||||||
|
- [ ] 公式关键分支、暖机边界、缺失值和除零场景均有自动化测试。
|
||||||
|
- [ ] 固定历史样本验证可重复运行，并以固定 golden 结果对比新旧实现或公式差异。
|
||||||
|
- [ ] 关键公式分支同时有人工确认案例和单元测试，golden 对比范围保持为少量固定样本。
|
||||||
|
- [ ] 未实现其他策略、前端页面或实时数据能力，且不改变现有市场数据同步契约。
|
||||||
|
|
||||||
|
## Notes
|
||||||
|
|
||||||
|
- Keep `prd.md` focused on requirements, constraints, and acceptance criteria.
|
||||||
|
- Lightweight tasks can remain PRD-only.
|
||||||
|
- For complex tasks, add `design.md` for technical design and `implement.md` for execution planning before `task.py start`.

||||||
|
## 来源
|
||||||
|
|
||||||
|
- 公式原文：`/Users/yuxuanhui/bcc-github/quant-project/zgnb/zgnb-project/docs/references/formulas/tongdaxin_xuangu_formula.txt`
|

|
||||||
|
|
||||||
|
## 已确认逻辑
|
||||||
|
|
||||||
|
`xg_composite` 先计算趋势白线、大哥黄线、BBI、短期/长期振荡器、KDJ、RSI、
|
||||||
|
振幅区间、缩量、大绿棒、异动、趋势和回踩条件，再执行 7 个子信号 mask：
|
||||||
|
|
||||||
|
1. 超卖缩量拐头 B
|
||||||
|
2. 超卖缩量 B
|
||||||
|
3. 原始 B1
|
||||||
|
4. 超卖超缩量 B
|
||||||
|
5. 回踩白线 B
|
||||||
|
6. 回踩超级 B
|
||||||
|
7. 回踩黄线 B
|
||||||
|
|
||||||
|
旧实现将 7 个 mask OR 为 `_存在B`，在 `select()` 中按优先级找到第一个匹配后
|
||||||
|
`break`。新任务明确改为返回全部命中分类。
|
||||||
|
|
||||||
|
## 迁移时必须保留的语义
|
||||||
|
|
||||||
|
- 数据升序；`REF` 使用前一交易日，不能用自然日偏移。
|
||||||
|
- `趋势白线 = EMA(EMA(C, 10), 10)`。
|
||||||
|
- `大哥黄线 = (MA(C,14)+MA(C,28)+MA(C,57)+MA(C,114))/4`。
|
||||||
|
- `短期` 使用 3 日最低价和 3 日最高收盘价，`长期` 使用 21 日窗口。
|
||||||
|
- 宽幅代码为 `68`、`30`、`4`、`8`、`9` 开头；普通代码如果最近 200 行内出现
|
||||||
|
超过 15% 的上涨，也使用宽幅参数。
|
||||||
|
- v1203 调整包含上涨十字星涨幅上限和原始 B1 的适当缩量分支。
|
||||||
|
|
||||||
|
## 旧实现与新任务的有意差异
|
||||||
|
|
||||||
|
- 新策略标识为 `zhixing_b1`，不再使用 `xg_composite` 作为运行时名称。
|
||||||
|
- 新分类值使用 `zhixing_b1_*` 前缀，不依赖旧 `SignalCategory.XG_*`。
|
||||||
|
- 新实现保留同一股票同一交易日的全部命中分类。
|
||||||
|
- 新实现目标日由显式 `target_trade_date` 决定，不取数据最后一行作为隐式目标。
|
||||||
|
- 新实现只使用新项目 PostgreSQL 的 qfq 日线；旧项目 CSV 中的 `market_cap` 是
|
||||||
|
初始化时取到的最新市值复制值，不能作为历史事实。
|
||||||
|
- 新测试运行时不导入旧项目；旧项目只用于生成固定 fixture 和 golden 期望。
|
||||||
|
|
||||||
|
## 现有 fixture 线索
|
||||||
|
|
||||||
|
旧项目已有完整 CSV 和 SQLite 信号结果，可从 `data/raw` 选取少量普通代码、宽幅
|
||||||
|
代码和已命中日期作为固定样本。由于旧实现没有记录同日多分类命中，需另加人工
|
||||||
|
构造样本验证新任务要求的多信号结果。
