Marks are the pools' prices times what is held; selling would move them. Held is the wallet's balance where it could be read, else bought less sold in these markets. Tokens that left this wallet by transfer count as neither sold nor held, so their cost sits in the open leg: a position moved elsewhere reads as down by what it cost here. 50 markets have no price to mark at. The Programmable record could not be read at all, so every figure above is a floor.
