How to Do Precision/Recall in Perl

The code above mines the buy and sell recommendations of CNBCs Jim Booyah! Cramer stored them in a CSV (with the --op=get parameter) and then analyzes how his picks turned out the next day (with the --op=check option). I would like to write the data to/from a SQL database and generate a report using LaTeX and let skeedaddy know. Ideally, this little project would get a shout-out on the show, but before that happens, I'd like to finish the two things above. The code is in perl, only because there is no better way to parse HTML than HTML::TreeBuilder.
