suncong/ylabels-noon

return_y_noon2 午间收益率标签 由掘金 A 股分钟收盘价生成。return_y_noon2.pkl 与 return_y_noon2.parquet 保存同一 pandas DataFrame:行索引为 Python date,列为六位股票代码, 值为小数收益率(0.01 表示 1%),保留 NaN。上传前精确校验两种格式和完整日期序列, 同一次提交发布两个数据文件及本说明。此数据集独立于 suncong/ylabels。 午间交易日 11:35 运行,使用 pandas_market_calendars 的 SSE 日历判断休市和数据新鲜度,只使用严格早于运行日期的行情目录;掘金数据在每日收盘后更新。 默认标签截止日为运行日前倒数第二个行情日期,最后输入日为运行日前最后一个行情日期。 例如 2026-09-23 运行时,最后输入日为 2026-09-22,标签截止 2026-09-21。 历史计算序列依据有效行情目录;定时任务另外核对最后两日与 SSE 日历一致,缺少昨日行情时失败而不回退。 默认起点 2021-12-22… See the full description on the dataset page: https://huggingface.co/datasets/suncong/ylabels-noon.
