I have made some updates to the DSS as rewritten by kw.
1. The computation of the "period low" and "period high" really refer to
The lowest low and highest high, I believe. Therefore, this indicator
should take 3 series as (default) arguments: {I:Prices HIGH}, {I:Prices
LOW}, and {I:Prices CLOSE}.
2. The high, low, and close are all used in the computation of the
stochastic.
3. The dependency should just be 1 day on the smoothing intermediate
series, as the dependency mechanism takes care of the rest. This is
important, as the EMA gives quite different results if a longer
dependency is requested (in effect, it lengthens the smoothing period).
4. I added a check in the calculation of DSS to avoid divide by zero
errors.
5. Added a check for constant input.
