research.rt_signal
这是已经产出的研究信号与市场状态中的“Daybreak 实时信号”数据集;一行由 dedup_id、direction、triggered_at 定位,主要字段包括 detector、signal_type、symbol、instrument_id、trade_date。

GRAIN & TIME
KEY FIELDS
dedup_iddirectiontriggered_atRECOMMENDED JOINS
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。
ref.calendaron market + trade_date(有 market 时)需要计算交易日偏移时联接交易日历;无 market 字段时先确定适用市场。
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。

该资产没有 PIT 契约。普通 rows 端点仍按当前公开读模式返回数据;不要把它表述成历史时点快照。
COPY-READY CALLS
同一数据集可用 HTTP、Python SDK、CLI 或 MCP;Key 始终只通过环境变量/Bearer Header 传递。
