ref.instrumenton instrument_id用 instrument_id 补充证券代码、名称、市场、交易所和资产类型。
event.candidateon candidate_id用 candidate_id 查看候选产生时点、状态和策略上下文。
event.source_documenton source_doc_id用文档标识回溯标准化原文和来源信息;先核对两表字段口径。
HOW TO QUERY SAFELY
先用 catalog 确认当前契约;可按 catalog 中列出的 filters 进一步缩小范围;单页最多 5000 行,响应有 has_more 时原样传回 next_cursor 继续分页。
