What is Stochastic RSI?
Stochastic RSI, from Tushar Chande and Stanley Kroll, applies the stochastic formula to RSI values instead of price. It measures where RSI sits within its own recent range, which makes it faster and more sensitive than RSI.
Stochastic RSI formula
| Output | Calculation |
|---|---|
| StochRSI | (RSI − lowest RSI) ÷ (highest RSI − lowest RSI) |
| %K / %D | Smoothed StochRSI and its moving average |
How to read Stochastic RSI in your code
| Signal | Meaning | Condition |
|---|---|---|
| Overbought | RSI at top of its range | valueFastK above 80 |
| Oversold | RSI at bottom of its range | valueFastK below 20 |
| Bullish cross | RSI momentum turning up | valueFastK crosses above valueFastD |
Limitations: It hits its extremes very often. An overbought reading is common in ordinary uptrends and is not a sell signal by itself. Nothing on this page is financial advice.
Compare the last two closed Stochastic RSI values
Use backtrack=1 to skip the candle still forming, and results=2 to compare the last two closed candles. Arrays run oldest first.

Which Stochastic RSI settings can I change?
You can set rsiPeriod, stochasticPeriod, kPeriod, dPeriod. See the parameters table above for defaults.
