The fourth column is refined metal traded, the fifth is key(s) traded. Next to each trade I wrote in notes that help you see action taken, if any. When I say the price matches sheet it either exactly matches or, most often, is in a range around the number on the sheet. That is why we have a "+/-" or 2 numbers listed because of this implied range. Again, there are no exact prices.
Actual trade prices always trump voting on prices. Prices are what people pay, not what self-interested owners think their item is worth.
We will post more of these as we get closer and closer to the site relaunch.
