The newest addon for guilds is Market Tracker that is currently being developed with guild pricing in mind for players to sell items like Chromium Plating in game

After downloading Libtext you will be able to find more information on the addon that is a small part of the Immersion Quests that are being developed on a larger scale in Elder Scrolls Online. The Data Loader is not available in the addon screen; however when a player logs into their game the loader loads information in game

The first addon is the Market Trader pricing assistant that shows the price of Chromium Plating that will go down in price once you sell the item in game. Thanks to OneSkyGod for helping understand the pricing information in the item. The Market Tracker only has information on Chromium Plating as the first item to sell to a merchant in game as later items will be available for the tracker to process information on prices of in game items

The second addon can be seen in two places that is called the Data Loader that can be seen when first logged into game. The current development is seen in Xbox and will be available in other platforms as the addon is fully developed

The in-game price shows a decrease in pricing from Chromium Plating that is an indication of a reduction in price for other in-game items along with Chromium Plating reduced in value from first glimpses into the pricing model. The pricing model is different in multiple platforms that has to be studied in order for the game to be understood if prices are different in PlayStation or Steam
