Stochastic RSI
Applies the Stochastic formula to RSI: where is RSI within its own recent range?
L’idée en termes simples
RSI often stays between 30 and 70 for long stretches and rarely reaches extremes. Stochastic RSI rescales it, so turning points become more visible.
Mode de calcul
RSI(14), then where today's RSI sits between its 14-candle lowest and highest values, smoothed by 3, with a 3-period signal line.
StochRSI = (RSI − lowest RSI) ÷ (highest RSI − lowest RSI) × 100 over 14
%K = SMA(StochRSI, 3), %D = SMA(%K, 3)Comment l’utiliser
- Above 80 / below 20: short-term overbought / oversold.
- %K crossing %D signals short-term turns.
Tirer des conclusions
- Very fast; best used to time entries in the direction of a bigger trend.
Exemple
In an uptrend Stochastic RSI drops below 20 during a pullback and %K crosses up through %D: a short-term buy signal.
Les prix des exemples sont donnés à titre d’illustration.
Points de vigilance
- Extremely sensitive: many signals, many false.
