"Why is there no search filter in the Global Trade HQ?
Global Trade HQ works in a way that every item sold is created by another player. Certain items have a higher demand than others, and generally the high demand items will sell a lot quicker than the low demand ones.
If we added a feature that would enable players to search for a specific item type, it would make the high demand items sell incredibly fast. This would then result in the high demanding items completely disappearing from the market, and almost no one would find the type of items that they need.
We strive to make the Global Trade HQ a balanced and fair place, regardless of your connection, device, or location. Adding a search of filter functionality would make it highly unfair for those who are not able to quickly grab each new item that is put up for sale."
As a friend of mine once said, "There's a difference between having an answer, and liking the answer."
