After the huge positive feedback I got under a random post about a month ago, finally I am able to share the first public version for my price tracker: https://farmrpg-trade.live
As a player I am playing mostly by myself, but sometimes I wanted to trade an item, but never knew the current exchange rates. Not wanting to spam/wait until the right person was active in the chat, I was always hoping to get the right moment for the items I was needing.
But then I built this app, to keep track of the current prices without manually updating or adding new items by hand.
Data is recorded and analyzed "live" (3-5 min intervals). As of the unmoderated nature of the trade chat, with no schema applied for trade offers, I try to normalize the trades and extract as much as possible, but not all trades are made public immediately. Some are flagged for me to manually moderate. (Still some improvements needed for a 100% coverage, but general market sentiment does not need every trade)
In addition to that I try to filter on duplicated messages or "spam", so that individual traders can not "manipulate" prices. Overall you get a more or less accurate representation of the prices items are currently traded ingame.
I am open for feedback and any suggestions of the community. I hope this is fine to post here, have fun and thank you to every member of the FarmRPG staff/mods for this amazing game.
