为什么第一节课(9:30)被取消了
它将第一个周期返回为10:00。这是不正确的
我做错了什么
import pandas_market_calendars as mcal
nyse = mcal.get_calendar('NYSE')
early = nyse.schedule(start_date="2020-07-02", end_date="2020-10-14") # .strftime(date_fmt)
dates = mcal.date_range(early, frequency="30min")
dates = dates.tz_convert('US/Eastern')
dates
