我正在制作一个股票分析程序，但为此，我需要纽约证券交易所的股票历史数据API。
我到处搜索过，但找不到有用的解决方案（例如Yahoo / Google Finance API已关闭）。
我尝试使用Alpha Vantage API，但似乎没有输出每只股票的平仓/开仓价值。
是否有另一种方式可以使大众访问历史数据，而无需直接从Yahoo Finance下载每只股票的.csv文件？
谢谢！

python yahoofinancials模块可以轻松为您处理此问题。除了每月，每日等历史股票数据之外，它还可以为您提供有关Yahoo财务上任何公司的所有基本财务数据（资产负债表，损益表，现金流量，比率等）。
您可以使用pip install yahoofinancials安装它。它不依赖于封闭的Yahoo API，也不需要配置网络驱动程序即可工作。另外，无需注册或API密钥。它通过散列在每个Yahoo Finance网页中找到的数据存储对象来工作。
您可以将单个股票/指数行情收录器作为字符串传递，也可以将一系列股票代码传递进来，以一次提取多个股票/指数。数据也很容易放入Pandas数据框中进行分析。
$ pip install yahoofinancials
多股票报价拉示例：
from yahoofinancials import YahooFinancials
tech_stocks = ['AAPL', 'MSFT', 'INTC']
bank_stocks = ['WFC', 'BAC', 'C']
yahoo_financials_tech = YahooFinancials(tech_stocks)
yahoo_financials_banks = YahooFinancials(bank_stocks)
tech_cash_flow_data_an = yahoo_financials_tech.get_financial_stmts('annual', 'cash')
bank_cash_flow_data_an = yahoo_financials_banks.get_financial_stmts('annual', 'cash')
banks_net_ebit = yahoo_financials_banks.get_ebit()
tech_stock_price_data = tech_cash_flow_data.get_stock_price_data()
daily_bank_stock_prices = yahoo_financials_banks.get_historical_stock_data('2008-09-15', '2017-09-15', 'daily')
用法示例：
from yahoofinancials import YahooFinancials
yahoo_financials = YahooFinancials('WFC')
print(yahoo_financials.get_historical_stock_data("2017-09-10", "2017-10-10", "monthly"))
