"SlowStochastic" (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 smoothed with a 3-period moving average. The second is a 3-period moving average of the stochastic.
FinancialIndicator["SlowStochastic",n1,n2] uses extremes over the last n1 periods and an n2-period moving average.
