What it does
Stochastic RSI applies the Stochastic formula to RSI values instead of price: it measures where the current RSI sits within its own highest-to-lowest range over the lookback, typically 14 periods, scaled 0 to 100 (or 0 to 1). The raw value is usually smoothed into %K (3-period) with a %D signal line (3-period) on top. The result is a much faster, more sensitive oscillator that reaches extremes long before RSI itself does.
How to add it
Click Indicators (ƒx) in the header.
Search “Stochastic RSI” and click the result.
Hover its legend row and click the gear to open settings.
How traders use it
- Use 80/20 zones: readings above 80 are overbought and below 20 oversold, occurring far more often than on plain RSI.
- Trade with the trend: in an uptrend, buy when StochRSI drops below 20 and %K crosses back above %D; ignore overbought sells.
- Use it for timing, not bias: let RSI or a moving average define direction and let StochRSI time the pullback entry.
- Watch the 50 midline for momentum shifts within the RSI range.

Tips
- Merge multiple oscillators into one pane from the legend ⋯ menu to compare them on a shared axis.
- Double-click the plot to open settings directly, skipping the legend hover.
- The pane keeps its height in saved layouts, so size it once and it survives reloads.
Watch out for
- As a derivative of a derivative it is extremely jumpy, spends much of its time pinned at 0 or 100, and generates many false signals without smoothing and a trend filter.
- An extreme StochRSI reading does not mean price is at a true extreme, only that RSI is at the edge of its own recent range.
