Slow Stochastic

Slow Stochastic is a momentum oscillator that measures the market strength by comparing the closing price of a security with its price range over period of time. The oscillator is bounded to the range from 0 to +100 and is consisted of two lines: SlowK, derived out of Fast Stochastic by applying 3-day Simple Moving Average (SMA) to its FastK plot, and its smoothed version SlowD. Crossover of SlowK and SlowD with overbought/oversold levels generates sell (above 80) and buy (below 20) signals respectively.
%K = [ (C - L) / (H - L) ] * 100
SlowK = MA(%K)
SlowD = MA(SlowK)
where:
%K – FastK
C – the most recent closing price
L – the Lowest price during period
H – the Highest price during period
MA – Moving Average
