SSO (Slow Stochastic Oscillator)

The SSO (Slow Stochastic Oscillator) is a smoothed version of the Fast Stochastic Oscillator. It is less sensitive to price changes than the Fast Stochastic Oscillator, which results in fewer, but more reliable, trading signals. It is calculated by smoothing the %K line of the Fast Stochastic Oscillator with a simple moving average.
