Developed by John Ehlers, the RSI-based inverse Fisher Transform is used to help clearly define trigger points.
The normal RSI indicator is calculated and adjusted so that the values are centered around zero. The inverse transform is then applied to these values.
John Ehlers recommend to smooth the result of the calculation with a weighted average, but that’s not the case into this one.
The default RSI period is set to 14.
