%
% Calculate the @var{lead}ing and @var{lag}ging moving average of an
% @var{asset}. If given, @var{alpha} is the weighting power of the
% delay; 0 (default) is the simple moving average, 0.5 would be the
% square root weighted moving average, 1 would be linear, 2 would be
% squared, ..., and 'e' is the exponential moving average.
%
% If no output is requested the data is plotted. The plots are drawn
% in the following order: asset, lag, lead. If output is requested, no
% plot is generated.
