Something to think about as the millisecond tick by today: how much money you're not making from the slight discrepancies between the values of securities on the world's international exchanges. Developed by suburban Chicago-based financial data company Nanex, this visualization shows, at highly reduced speed, the automated trading activity that took place on Johnson and Johnson's stock May 2.
