In this system designed for a leading ECN, Uncharted renders an intuitive, integrated view of supply and demand (buy and sell orders), transaction history (trades), and analytics (e.g. volume distributions and VWAP), in real time in a browser. Giving visual form to the financial market enables a trader to see developments more quickly, gaining competitive advantage. This innovative visualization design earns praise in David Leinweber’s book Nerds on Wall Street.
