Stochastic Relative Strength Index, Stochastic RSI or StochRSI is a momentum oscillator that applies the stochastic formula to Relative Strength Index (RSI) values instead of price. It enhances sensitivity to short-term moves and ranges from 0 to 1, with values above 0.8 typically marking overbought conditions and below 0.2 marking oversold levels. Often used to anticipate momentum shifts, reversals, and divergences, it appears in a separate panel with two lines: %K (main value) and %D (smoothed signal). This value is calculated by positioning the RSI within its range over a user-defined period, typically 14.
where:
Lowest RSI – the lowest RSI over the selected period
Max RSI – the highest RSI over the selected period
