Winkdex uses a proprietary formula to create a blended price for Bitcoins denominated in U.S. dollars. According to the Windex site, it is calculated by blending the trading prices for the top three (by volume) qualified Bitcoin Exchanges during the previous two-hour period. It volume-weights those transactions on a proportional basis.
