    The Fast Stochastic is a momentum oscillator that identifies the market strength by comparing the closing price of a security with its price range over period of time. Fast Stochastic is bounded to the range from 0 to +100 and is consisted of two lines: FastK and its smoothed version FastD. Crossover of either lines with overbought/oversold levels generates sell (above 80) and buy (below 20) signals respectively.

    %K = [ (C - L) / (H - L) ] * 100
    %D = MA(%K)

    %K – FastK
    %D – FastD
    C – the most recent closing price
    L – the Lowest price during period
    H – the Highest price during period
    MA – Moving Average

    KPeriodThe period the indicator uses to calculate FastK
    DPeriodThe length of the moving average to calculate FastD (%D)
    OverboughtThe price value to fix the overbought level at
    OversoldThe price value to fix the oversold level at
    The following Moving Average types are available for calculations:
    • Simple. Simple Moving Average (SMA) is applied to FastD.
    • Wilders. Wilders Smoothing is applied to FastD.
    • Weighted. Weighted Moving Average (WMA) is applied to FastD.
    • Exponential. Exponential Moving Average (EMA) is applied to FastD.
