获取不到最新的tick数据

ContextInfo.start = '2025-01-22 09:30:00'
ContextInfo.end = '2025-05-08 15:00:45'
A.start_time = datetime.strptime(ContextInfo.start, "%Y-%m-%d %H:%M:%S")
A.end_time = datetime.strptime(ContextInfo.end, "%Y-%m-%d %H:%M:%S")
download_history_data("123056.SZ","tick","20250401093000","")
download_history_data("123089.SZ","tick","20250401093000","")
data_now = ContextInfo.get_market_data_ex(['lastClose','high','low','lastPrice','volume','amount','settle','preClose','suspendFlag'],['123056.SZ','123089.SZ'], period='tick',start_time=A.start_time.strftime("%Y%m%d%H%M%S"),end_time =A.end_time.strftime("%Y%m%d%H%M%S"), dividend_type='none',fill_data=False,subscribe = False)

下载数据后，为什么获取不到五月份的tick数据
