I am looking at Zacks Stock Market Research web site and it has rankings for stocks like 'Sell', 'Buy', 'Strong Sell', 'Hold' etc.
I would like to retrieve historical data of the stock rankings going back a year. Has anyone tried that before ?
I'd appreciate if some one could shed light on how to do it ? I am open to using command line tools like Bash, Curl, Perl or Python and using REST APIs to do it.
