如何将 getReturns 与 Yahoo Finance API 结合使用 [英] How to use getReturns with the Yahoo finance API

问题描述

我在使用 R 包 getReturns 时遇到问题.自 5 月 17 日以来，我遇到了此错误:

I have problems with R package getReturns. I have encountered this error since 17th May:

文件中的警告(文件，rt"):无法打开 URL 'http://ichart.finance.yahoo.com/table.csv?s=AAPL&a=4&b=28&c=2014&d=4&e=27&f=2017&g=w&ignore=.csv':HTTP 状态为'404 Not Found'

Warning in file(file, "rt") : cannot open URL 'http://ichart.finance.yahoo.com/table.csv?s=AAPL&a=4&b=28&c=2014&d=4&e=27&f=2017&g=w&ignore=.csv': HTTP status was '404 Not Found'

看起来 ichart API 不再运行了.谁能帮我解决这个问题?有人知道如何解决吗?我在使用 quantmod R 包时遇到了同样的问题.

It looks like that ichart API did not run anymore. Can anyone help me with this issue? Does someone know how to fix it? I have encountered the same issue with the quantmod R package.

推荐答案

你可以按照我之前的发表，可能对你有帮助.

You can follow my an earlier post, which might help you.

我试过了:

library(quantmod)
# Create an object containing the Pfizer ticker symbol
symbol <- "PFE"    
# Use getSymbols to import the data
getSymbols(symbol, src="yahoo", auto.assign=T) 
# because src='google' throws error, yahoo was used, and even that is down

当我尝试其他来源时，它起作用了:

When I tried other source, it worked:

# "quantmod::oanda.currencies" contains a list of currencies provided by Oanda.com
currency_pair <- "GBP/CAD"    
# Load British Pound to Canadian Dollar exchange rate data
getSymbols(currency_pair, src="oanda")
str(GBPCAD)    

当我们使用 quantmod pkg 时，google 和 yahoo 似乎存在问题.

It seems there are issues with google and yahoo while we use quantmod pkg.

我建议您改用Quandl".请到 Quandl 网站，免费注册并创建 API 密钥，然后将其复制到下面:

I will suggest you to use 'Quandl' instead. Plz goto Quandl website, register for free and create API key, and then copy it in below:

# Install Quandl
install.packages("Quandl")
# or from github
install.packages("devtools")
library(devtools)
install_github("quandl/quandl-r")

# Load the Quandl package
library(Quandl)

# use API for full access
Quandl.api_key("xxxxxx")

# Download APPLE stock data
mydata = Quandl::Quandl.datatable("ZACKS/FC", ticker="AAPL")

对于 BSE 的 HDFC，您可以使用:

For HDFC at BSE, you can use:

hdfc = Quandl("BSE/BOM500180")
