How does it work?
A simple command such as ::pc-dream range set, which would then show an average price of the last 5-10 of that item sold on the market.
What rewards does it give?
Knowledge, a lot of spare time to staff.
How will it benefit server/players?
It will make finding prices a lot easier, and will also free up some time for staff members giving prices.
How could it be expanded in the future?
I'm not too sure, maybe you could add a full interface with a search bar etc.
What negative effect could this have? (Think eco, Item balances, Overpowered)
It could be awkward to code however I would not be surprised if you guys could pull it off. Other than that I can't imagine it ever causing an issue.
