stockSymbols() no longer works #275

Closed datafan11 closed 4 years ago

datafan11 commented 4 years ago

Description

stockSymbols() no longer works. Nasdaq.com redesigned their website. Please fix if you have time. The function is incredibly convenient. Thanks.

Note if you change the "www" in https://www.nasdaq.com/ to "old" then it appears to work. Don't know how long the "old" site will be available.

E.g., https://www.nasdaq.com/screening/companies-by-name.aspx?letter=0&exchange=AMEX&render=download

to

https://old.nasdaq.com/screening/companies-by-name.aspx?letter=0&exchange=AMEX&render=download

Expected behavior

Should return a list of US stock symbols.

Minimal, reproducible example

library(quantmod) 
symbols<-list()
symbols <- stockSymbols()
Fetching AMEX symbols...
Error in file(file, "rt") : cannot open the connection
In addition: Warning message:
In file(file, "rt") :
  cannot open URL 'https://www.nasdaq.com/screening/companies-by-name.aspx?letter=0&exchange=AMEX&render=download': HTTP status was '404 Not Found'

Thanks for the report. I'm closing this because stockSymbols() is in TTR. This is a duplicate of https://github.com/joshuaulrich/TTR/issues/83.
