New Yahoo Finance Quote Download Url

June 2, 2017

Overview

On May 18th 2017 the Yahoo ichart data download link http://ichart.finance.yahoo.com/table.csv stopped working. This link has for many years been a convenient access point for downloading historical quote data. It was simple to get quotes by building up this url with your symbol as a parameter.

If you are just starting off and it is only you I suggest for simplicity you create a directory called repos under your home directory.

For our example here I'm going to create a repo called project on a machine with the domain name of example-server.com. My username for this example will be user. Before continuing make sure you can ssh easily into your account on your server. In our example you would need to be able to execute the following command.
