RocketRSI
Highly responsive RSI variant using SuperSmoother and Fisher Transform.
Usage
Use for rapid cycle identification and reversal detection. The Fisher Transform converts the RSI distribution into a Gaussian-like distribution with sharp peaks at reversals.
Background
RocketRSI improves upon standard RSI by first smoothing the momentum with a SuperSmoother filter to eliminate high-frequency noise. The resulting RSI is then passed through a Fisher Transform to create clear, actionable signals at cyclical turning points.
Parameters
rsi_length(default: 8): RSI calculation periodsmooth_length(default: 10): SuperSmoother filter period
Formula
[ Mom = Price - Price_{t-(L-1)} ] [ Filt = \text{SuperSmoother}(Mom, SL) ] [ MyRSI = \frac{\sum \max(0, \Delta Filt) - \sum \max(0, -\Delta Filt)}{\sum |\Delta Filt|} ] [ RocketRSI = 0.5 \cdot \ln\left(\frac{1 + MyRSI}{1 - MyRSI}\right) ]
