What happens when you drive over a speedbump? It is uncomfortable and annoying. Simple as that. Why? Because your body is going through a change in acceleration called Jerk. Jerk is the rate at which acceleration changes. This is where money in market trading is. When the money moves the money is made, however, if you can make an algorithm for the rate at which the money moves then you can predict future speed of money movement and can invest accordingly. I Hope that makes sense :).
