It used to be that scrollong stock tickers carried every trade. In todays market that is obviously impossible. How do tickers like CNBC's or scrolling ones still at some brokers work. How do they determine which trades to show? Does anyone know?
CNBC has explained it a few times.... I think it's some algorithm they developed based on the stock's volume, number of trades, and how far the stock has moved up or down. Fletch
