用BaoStock判断一只股票昨天是否涨停~~

1.首先，必要安装好BaoStock.

  相信用pycharm的人从较多吧，等我找到pycharm安装库的教程再贴在这里吧~~

2.调用前先引用库：

import baostock as bstock

3. 具体实现代码:

stock_code = “600519”
yesterday = "2025-01-08"        #要据你的需要定义print("Baostock: ", end="")
bstock.login()print("Checking stock limit up status of " + yesterday)bstock_code = GetExchange(stock_code) + "." + stock_code
rs = bstock.query_history_k_data_plus(bstock_code, "preclose,close,isST", start_date=yesterday, end_date=yesterday)while (rs.error_code == '0') & rs.next():rdata = rs.get_row_data()  # string arraypreclose = float(rdata[0])close = float(rdata[1])isST = True if rdata[2]=='1' else Falselimit_rate = GetLimitUpRate(stock_code, isST)upperlimit = round(preclose * limit_rate, 2)  # keep %.2fif (close >= upperlimit):  # yesterday limit upprint(f"{MAGENTA}Warning: The stock hit the daily limit up yesterday{RESET}")# endif# end whileprint("Baostock: ", end="")
bstock.logout()

代码中用到的GetExchange函数，请参见前篇博文: Get exchange string for BaoStock-CSDN博客
