I thought I would throw a post up, demonstrating a "quick and easy" use case of the Stock API module, and simultaneously, give this site's GeSHi filter a quick test run.
A few days ago I encountered a site requirement asking for a simple informative stock quote block on a Drupal 6.x installation. The format required was something like:
NFLX 208.75 -1.30 Sep 13 7:30 EST
My initial thought was to enable the Stock module and simply configure and theme the built in block. The stock module will allow the management of multiple stocks on a per-user basis, and provides a block that displays this information in a table. There is no doubt that stock module is useful but in this instance it is overkill. All we are after is a simple quote from a single unchanging stock symbol displayed in a single line of text.
