我正在尝试使用该addValuesFromCSV方法将自定义 csv 数据添加到 PyAlgoTrade 中，但出现此错误：

2021-10-14 17:50:00 {'Open': 4886.0, 'High': 4888.0, 'Low': 4879.0, 'Close': 4883.0}
2021-10-14 17:55:00 {'Open': 4883.0, 'High': 4887.0, 'Low': 4874.0, 'Close': 4877.0}
2021-10-15 10:30:00 {'Open': 4910.0, 'High': 4922.0, 'Low': 4901.0, 'Close': 4907.0}

    139 
    140         assert(len(self.__values) == len(self.__dateTimes))

Exception: Invalid datetime. It must be bigger than that last one

这是我在 2021-10-15 10:30:00 之后的数据

日期 打开 高的 低的 关
2021-10-15 10:30:00 4910 4922 4901 4907
2021-10-15 10:35:00 4907 4907 4891 4896
2021-10-15 10:40:00 4896 4902 4886 4893
2021-10-15 10:45:00 4893 4901 4887 4897
2021-10-15 10:50:00 4897 4897 4879 4882
..................... …… …… …… ……
2021-11-15 17:35:00 4987 4989 4984 4985
2021-11-15 17:40:00 4985 4987 4975 4978
2021-11-15 17:45:00 4978 4990 4978 4987
2021-11-15 17:50:00 4986 4988 4970 4972
2021-11-15 17:55:00 4973 4975 4963 4965

以下是我的摄取代码：

from __future__ import print_function

from pyalgotrade.feed import csvfeed

feed = csvfeed.Feed("Date", "%Y-%m-%d %H:%M:%S")
feed.addValuesFromCSV("data/5min/fcpo_dec_jan_contract.csv")
for dateTime, value in feed:
    print(dateTime, value)

我不明白为什么说最后一个日期比上一个日期小。帮助将不胜感激

谢谢
