This is the CEDB Market. It will enable you to obtain information relating to the commodities available in Core Exiles.
Select a commodity from the drop-down list to view information on it, it values, and also what I consider to be a reasonable resale value. Please note, that the conservative values quoted are what I think these commodities are worth, you will almost certainly find them sold for a higher price, and likely for a lower price as well.
If the commodity is used in a schematic, then a link will appear at the bottom of the listing to allow you to view the schematics that require that commodity. You will also be shown the highest current price for the commodity on the GBM in game (if any of the commodity is listed)
