数据接口库股票接口 - A股选股与 Universe股票选股

股票选股

股票选股接口用于返回结构化候选池数据，供研究流程使用。

HTTP 方法与路径：GET /api/v1/stock/selection

接口定位与边界

  • 本接口提供的是“候选池数据”，不是投资建议，也不是自动交易信号。
  • 推荐配合以下文档使用，形成完整研究链路：
    • 方法论：/signal-client/methodology/indicator-guide
    • 预设边界：/signal-client/methodology/filter-presets
    • 操作流程：/signal-client/guides/stock-screener

入参

Path

| 路径参数 | 无 |

Query

参数类型必填说明
pagenumber否默认 1
pageSizenumber否默认 50
filterstring否筛选表达式

filter 使用建议

  • 先使用较宽条件获取可解释样本，再逐步收敛。
  • 不建议一次叠加过多条件，避免结果为空后无法定位原因。
  • 条件放宽时，优先放宽价格/趋势条件，不优先放宽风险与质量底线。

字段语义（研究口径）

下表列出高频字段在研究中的典型用途：

字段研究含义误用风险
PETTMDEDUCTED / PE_TTM估值与预期位置参考单看估值忽视盈利质量
ROE_WEIGHT盈利效率线索不拆来源会误把杠杆当质量
DEBT_ASSET_RATIO杠杆与偿债压力线索不做行业校准会误判
PER_NETCASH_OPERATE / PER_FCFE现金流质量与可持续性线索忽略周期会误读短期波动
NET_INFLOW / DDX资金关注度线索把资金流当基本面
MACD_* / KDJ_* / BREAKUP_MA_*趋势验证线索把技术信号当自动指令

说明：字段用于证据组织，不直接映射买卖动作。动作应由交易计划中的触发条件决定。

响应

响应外壳：成功时 JSON 含 success、data、可选 message，见 统一响应体。

响应示例

对应请求 GET /api/v1/stock/selection。字段以线上为准。

请求示例

curl -sS -H "Authorization: Bearer <API_KEY>" "http://localhost:4000/api/v1/stock/selection"

最佳实践

  1. 从低耦合条件开始分页拉取，先看样本分布与字段质量。
  2. 将结果视为“候选池”，进入二次研究而非直接执行。
  3. 在消费端保留筛选版本、时间戳和关键条件，便于复盘。
