Description
Statistical measure of the lopsidedness of a distribution of values
Syntax
Skewness(expr, count)
Parameters
expr  data series formula
count  lookback period

Skewness is calculated in the same way that Excel calculates the SKEW.P function, which is as if the set of count values is the entire population.
The specific formula used is shown below, in the "skew" item:
This also illustrates how these statistical functions could be calculated in the Data Section of a script, though since they're provided builtin, there's no reason to do so.
