"FastStochastic" (Financial Indicator)

Is a statistical indicator.

Is computed using the high, low, and close prices.

Returns two time series. The first is the stochastic, which expresses the current price as a percentage of the price range over the last 14 periods. The second is a 3-period simple moving average of the stochastic.

FinancialIndicator["FastStochastic",n1,n2] uses extremes over the last n1 periods and a n2-period moving average.
