download_history_data取不到当天上交所的tick数据

xtdata.download_history_data('600000.SH', period='tick', start_time='20250618', end_time='20250618', incrementally = False)

data_dict=xtdata.get_local_data(field_list=[], stock_list=['600000.SH'], period='tick', start_time='20250618', end_time='20250618', count=-1,dividend_type='none', fill_data=False, data_dir='')

这几天取不到数，为什么

同问
