FastStochastic

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 uses extremes over the last n1 periods and a -period moving average.
