  carries real-world questions with a yes-and-no bar; clerks chalk new prices as the world moves.

  description: 'The board lists open markets with live prices. Winning shares pay 100 credits
    each. Use predictions (or use market/use exchange) to trade, active and closed to review your
    contracts, and collect to withdraw resolved winnings. The house takes the other side of every
    trade; players never trade with each other.'
