我想为美国证券交易所，纽约证券交易所，纳斯达克证券交易所上市的美国股票编制一个筛选器。但是我很难处理月度股票价格信息。 我已经在下面制作了一些代码来获取雅虎财务的月度股票价格。
问题1：如何在AMEX，NYSE，纳斯达克上市所有股票？
问题2：我想做最近三个月的close_price＆gt; open_price等条件判断，以及当月的close_price＆gt;上个月的close_price，上个月的close_price＆gt;每个的前一个月的收盘价自动收报机（判断一些股票的起义趋势）
问题3：我的输出可能有问题？ 你可以帮助我摆脱这种情况吗？谢谢。
import pandas_datareader.data as web
import pandas as pd
all_data = {}
for ticker in ['MTW', 'CYH', 'PAH', 'FCX']:
#try:
all_data[ticker] = web.get_data_yahoo(ticker,'01/01/2016',interval='m')
print(all_data[ticker])
#print(all_data)
open_price = pd.DataFrame({tic: data['Open']
for tic, data in all_data.items()})
close_price = pd.DataFrame({tic: data['Close']
for tic, data in all_data.items()})
volume = pd.DataFrame({tic: data['Volume']
for tic, data in all_data.items()})
#date = pd.DataFrame({tic: data['Date']
#for tic, data in all_data.items()})
print(open_price,close_price,volume)
#except:
#print("Cant find",ticker)
输出如下：
