@item Chikou (blue)
The chikou line drawn in blue is closing prices shifted back 26 days.  It's
interpreted relative to those past prices, with chikou above being bullish or
below being bearish.  This is similar to the kind of comparison momentum makes
(@pxref{Momentum and Rate of Change}).
@end table

The time periods of 9 days and 26 days are parameters in Chart (@pxref{View
Style}).  When Hosoda designed the system Japanese markets traded 6 days a
week, so 9 days was @m{1 1\over2,1 1/2} trading weeks and 26 days was a month.
The same calendar times in today's 5 day weeks can be had with 7 and 22 days.

@cindex Range Midpoint
@anchor{Range Midpoint}
@subsection Range Midpoint

An N-day range midpoint like the tenkan, kijun and cloud lines is also
available separately as ``Range Midpoint'' if you want to experiment.  It's
under ``Low Priority'' in the averages list.

=item C<< App::Chart::Timebase::Years->new_from_iso ($start) >>

=item C<< App::Chart::Timebase::Decades->new_from_iso ($start) >>

Create and return a new timebase object representing the given
days/weeks/etc type of period, and with a 0 at the given C<$start> date.
C<$start> is an ISO format string like "2007-12-31".

    my $timebase = App::Chart::Timebase::Days->new_from_iso ('2008-05-01');
    my $iso = $timebase->to_iso (5);
    # $iso is '2008-05-08'  (weekday 5 counting from 0 at 1 May)
