Be your own market maker, where the price is just the midpoint of your last two offers and every bid moves it.

How to play
Each round you post a buy or sell offer with a quantity and a price. Your reference price is simply the midpoint of your two most recent offers, so it follows wherever you push it. Fair value drifts on its own, and your job is to buy below it and sell above it for profit.
