Can you specifically elaborate how the stochastic RSI is derived. The unsmoothed StochRSI is also do not give correct result.100x(( Current RSI (say14)-Min(RSI14 lookback)) / ((max (Rsi14 lookback)-Min (RSI14 lookback)). Then I am not able to calculate the Smoothed version applying K% (which series) and D% (which series). It will be great help Sir.
