Stochastic indicator

 Stochastic indicator

The Stochastic Oscillator indicator was created by the famous trader George Lane. He noted a certain cyclicity in the behavior of the price: moving from one level to another, it periodically falls into a state of overbought, then oversold. Stochastic shows the ability of buyers and sellers to set the closing price at the highs/lows reached.


Stochastic is a normalized oscillator, built in a separate window under the price chart, consists of two lines: %K - fast and %D - slow. Values ​​vary from 0% to 100%, signal lines are drawn at the levels of 20% and 80%, which highlight zones of oversold (from 0% to 20%) and overbought (from 80% to 100%). These zones are used to search for signals to buy or sell a financial instrument.
