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.
