Hoard is a DataBroker module addon and as such needs another addon to display it. I recommend using Candy.
Hoard is a gold and currency DataBroker module. Now you may ask, why would you want yet another one of these?
Gold module tracks gold across all of your chars on same (connected) realm and also displays some session and history data about profits and losses. The gold module will also track when you send gold in mail to alts, doesn't mark the money sent as losses and keeps your total in check. If you care about that sort of a thing.
Currency module will allow you to track your characters' currencies up to four currencies at a time. By default it will display a global profile but you can change that to per character profile instead.
To freely place the DataBroker modules anywhere check out my DataBroker display addon Candy.
