3) Indicator test using spreadsheet to confirm issue. Indicator on indicator example:

I just checked the Fast Stochastic RAW K with an RSI and the calculation is wrong.

Steps to recreate

a) Add Stochastic RSI as comparison (14). There is only 1 parameter for both the RSI and the HH/LL look-back in the Stochastic calculation.

b) Add basic RSI (14). Ignore smoothing or set to 1.

c) Add Fast Stochastic (Raw K) 'Based On:' RSI in a) above. Use 'Input Data for Last = RSI' and Ignore %D.

The shape of synthetic Stochastic RSI closely mirrors the RSI except in amplitude and is no longer bound by 0 - 100, lower and upper ranges. The indicator output is incorrect.

*** Note re Stochastic RSI
The RSI looks back over period of Bars to arrive at RS, then RSI of close. The Stochastic looks back to derive values from the HH/LL so why is there a Reference to RSI Average type? There is no smoothing element?
