Market of One

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.

• Post a buy or sell offer each round
• Your reference price tracks the midpoint of your last two offers
• Fair value wanders on a seeded path you must read
• Hit your target net worth to win

Controls

• Desktop: click the buy/sell toggle and the quantity and price steppers, then confirm
• Phone & tablet: tap the same on-screen controls

Game modes

• Daily: one shared seeded market
• Practice: a fresh random market each time

Tips & strategy

• Remember an aggressive offer drags your own reference the wrong way for next turn
• Nudge the midpoint gently when fair value is close, and pounce when it gaps
• Plan two moves ahead, since your current and previous offer both set the price
