The STOCHASTIC indicator shows us information about momentum and trend strength. As we will see shortly, the indicator analyses price movements and tells us how fast and how strong the price moves.
This is a quote from George Lane, the inventor of the STOCHASTIC indicator:
Stochastics measures the momentum of price. If you visualize a rocket going up in the air before it can turn down, it must slow down. Momentum always changes direction before price. George Lane, the developer of the Stochastic indicator
