Looking for a trade tracking addon, does it exist?

[PiyoPiyo]

I've been looking for a while not but have not found anything like it. I was wondering if there is an addon that will track all of my trading activities. Similar to what beancounter does with tracking my AH activities.
I ask this because recently i mis-traded a stack of items during an instance, and when i realized that i had traded the wrong items i contacted the people who were in the group with me if i had given them the items in question. However all it did was make the people angry and say that i was accusing them. In the end i was down about 500g.
