SaneBull contextual stock symbol information plugin.
This plugin will give you the flexibility of linking stock symbols to keywords (by default, the keywords are stock symbols). For a visual example, please see this example blog post.
By default, we open the Short symbol display, but upon clicking the symbol, a full view is presented.
This plugin installation is no different from any other WordPress plugin. All you need to do is unzip the files and upload them to your /wp-content/plugins/ directory.
After uploading, activate the plugin through the WP Admin -> Plugins page. To use it, you will need to define the keywords in Options -> SaneBull Quote.
That's it! From now on, whenever you use any of the specified keywords in your posts or pages, they will automatically convert to the SaneBull Live Stock widget.
