Use WP to manage your stocks watchlist. Publish your watchlist on your blog with live prices from Yahoo Finance.
The stock symbols are stored in the WP database.
No, the plugin checks if the Stocks Watchlist table exists. If it doesn't then the table is added automatically.
Nothing, except add your stock symbols to the database. There is a PHP Class in the plugin that does this automatically. Just make sure you spell the stocks symbol correctly.
Add this code to your template - <?php swl_output() ?> - where you want the watchlist to show.
I'd love to. Just let me know what you want added and I'll give it some consideration :)
