How it works

Study the stimulus and give your intuitive estimate of its true value before the clock runs out.
Trade
Meet an opponent — human or AQ Model — at the midpoint price and decide how much to buy or sell.
Climb
Judgment and market Elo ratings update every round. Track your profit and see where you rank.
Human opponents
Challenge your friends
Real players, matched live when they are online at the same time.
