@Solensolen 基本上理解的正确把，但是start=0代表从当前时间点能获取的最近的一个bar开始计算的，至于对于日k线来说是不是昨天，根据交易日休市等的情况还有所不同...

    __data = pd.DataFrame()
    with api.connect(ip, port):
        code = [code] if type(code) is str else code
        for id_ in range(int(len(code) / 80) + 1):
            __data = __data.append(api.to_df(api.get_security_quotes(
                [(__select_market_code(x), x) for x in code[80 * id_:80 * (id_ + 1)]])))
            __data['datetime'] = datetime.datetime.now()
        data = __data[['datetime', 'code', 'open', 'high', 'low', 'price']]
        return data.set_index('code', drop=False, inplace=False)
