I have heard several players asking for price guide and some have had a sort of a "Price guide" in their house, however, I do not think that it is very accessible nor reliable taking into account the fact that there are many items, and the prices vary with time.
Hence, I was wondering if the game could establish another tab on the forums to show the max and min prices of items that were in transaction every hour.
The whole system updates itself hourly so as to get the latest max,min and average price for the items. I know this can be difficult as there are many items being traded everyday and there are many items that can represent money, so perhaps players who traded a certain item can indicate the price of the item on the tab and the tab will take the lowest and highest prices that were indicated. If possible, an average can be taken of all those who entered a price.
In case you cannot visualize, for example, player A traded a crab dagger for 200 trochus and he keyed the price of 600 gralats into the system, another player who sold his crab dagger at 50 shrooms keyed in a price of 250 gralats, then the system will take the price of 250 gralats as the lowest price for the item. same for the max price.
The whole systems works on trust and every player has to be honest with their prices.
I am aware that there may be some players who wants to sell their items at high prices so some may resort to faking their prices. So, the system can get the average of the prices of the item and show the name of the players who typed in their prices, to minimize fake prices. (If a player types in too many times, it is obvious he or she is lying) The system also works in a supply-demand way, so players can check the number of transactions of the item hourly (as the system updates hourly), a high transaction of an item indicates a high demand and it would be the best time to sell a particular item.
I don't know if the admins would allow. feel free to voice out your opinions.
