by logic it should be a % of a normal price.
so salerate=100 means - you get 100% of item price, while sellrate=0 would mean mean you get NOTHING
btw I like the devs to again consider the changes I proposed for the buyback system which was supose to address issue of extrimly short sell/buy range where your CHA ment almost nothing:
