Scrape financial stock movements - repost

Requirement is to scrape symbol movements (prices, etc) from [login to view URL] to a file stored locally on the computer. From [login to view URL] main page, pick Stock Picks-> Mad Money Stock Screener option. On the middle left of the page you can see symbols listed alphabetically as well as some date filter options to the right. With the filter "Showdate = Last Quarter" i need all stock prices as shown. Note a bug on the website wont let you scroll through all the symbols (there are about 1668 stock symbols). You can define whatever structure for the output file as is reasonable - i would just need to review the structure proposed before you implement it first. The problem should be robust and address cases where website is not available or takes long to load, etc Picture of important part of the page to be scrapped is attached. thanks
