The Double Smoothed Stochastics indicator was proposed by William Blau and Walter
Bressert. The calculation of DSS values is similar to Stochastic indicator, the difference is the use of double exponentially smoothing.
The interpretation of DSS values is the same as for Stochastic - the values above 80 indicates the overbought state of the market, the values below 20 indicates the oversold market state.
