ORDER BY  报错 帮我看下哪里有问题

import dai


import pandas as pd

# 提取股票数据
stock_sql = """

stock_data = dai.query(stock_sql, filters={"date": ["2019-12-01", "2024-11-11"]}).df()
stock_data_cleaned = stock_data.dropna()

# 仓位分配
#设定持仓股票数量
count_num = 3
# 假设 stock_data_cleaned 是包含股票数据的 DataFrame,并且已经计算出了 'ce' 列
filtered_df = stock_data_cleaned.sort_values(by=['date', 'ce'], ascending=[True, False]).groupby('date').head(count_num)

# 设置仓位
filtered_df['position'] = 1 / count_num

# 计算 'ce' 的排名
filtered_df['score_rank'] = filtered_df.groupby('date')['ce'].rank(ascending=False).astype(int)

# 重命名 'ce' 为 'score'
filtered_df = filtered_df.rename(columns={'ce': 'score'})
# 设置回测起始时间和终止时间
start_date = '2020-01-01'
end_date = '2024-08-14'

这个报错提示 Parser Error: syntax error at or near "ORDER"\n

这里的ORDER BY 应该怎么写39-41这几行

我下面的照抄的模板里面的购买股票仓位设置 这里也帮我看下写法有没有问题
