Thought this was interesting and a few Sythe users could benefit from this.
Basically it takes players offers of what they are wanting to buy or sell their items at and it plots the recent data of this on a curve and shows the average price people will pay with an upper and lower, similar in fashion to the grand exchange. It also shows the high alchemy value. This is continuously updated by all the players' offers so it is effectively community driven instead of having a clan monopolize things insisting that an item is definitely worth one thing when other people have a different opinion of said item's value.
"Thanks", "Nice" etc. = SPAM
