This is the StochasticRSI indicator described in Chapter 8.  This indicator is a ratio of up prices compared to the sum of up and down prices, and the stochastic portion looks at the highs and lows over the same period.  It may be combined with the Cyber8_StochasticRSITrigger indicator to create a trading system.

PriceIn = defaults to Close, which is correct for this indicator

RSILen = defaults to 8

StocLen = defaults to 8

WaveLen = defaults to 5 but change to 8 to match the book (called WMALength in book)
