[Layback_]

So, I am trying to track couple of currencies (money, order resources, etc.) when there is an update (either gain or loss).

I guess money could be easily tracked via PLAYER_MONEY event, but still ain't sure of other currencies.

According to the description on Wowpedia, CURRENCY_DISPLAY_UPDATE event fires 'every time the UI need to draw the currencies list' and I'm not quite sure of which UI it is referring to.

CHAT_MSG_CURRENCY seems to handle gain, but not too sure about loss.
(Never seen a message on loss)

What could be the best possible solution, here?
