Chart
Chart downloads and displays stock and commodity charts, using data from various sources, mainly Yahoo Finance.
As of Sept 2024, Yahoo Finance has some hoops which an application must jump through and which are defeating daily data downloads, but latest quotes might be ok.
It features various indicators and averages, and data downloading. There's tie-ins to look at indicators from Genius Trader and TA-Lib. Read more in the online manual (one web page per node, or there's a single-file HTML in the sources below).
The current state is only keep-it-going and there's a couple of niggling problems (Bugs below).
Chart is free
software (free as in freedom, and also free as in no cost). Chart is
published under the terms of the
GNU
General Public License (v3 or up).
Download
To run Chart you need
Perl
5.10 up, Gtk2-Perl 1.220 up,
and a list of Perl modules as long as your arm, per the
Makefile.PL in the sources but available from
CPAN.
Download version 274 here, either the
.tar.gz source, or a Debian package out of
my repo.
App-Chart-274.tar.gz(957k, and sig)
chart_274-0.1_all.deb(664k, and sig)
The sig files above are Gnu PG ascii
armoured signatures, generated from my key.
There's a SIGNATURE file inside the .tar.gz for
cpansign
too.
For the deb, dependencies not in the Debian archive are in the
"other" section of my repo, including Genius Trader
and TA-Lib tie-ins. Otherwise try
dh-make-perl.
Bugs
There's some sort of bug in the drawing when doing Control-U download updates at the same time as viewing. It's supposed to redraw as the download proceeds and at completion, but something bad happens to cause no drawing, even on a normal "expose" window overlap and reveal. The suggested workaround is to go "n" next and "p" previous which forces a redraw. Control-L is a redraw too, but doesn't help when stuck in the bug.
The automated symbol lists (All and Alerts) sometimes get themselves jumbled or duplicate entries. Running the "Tools/Vacuum" rectifies.
Older sources can be found in
my directory at
backpan (big), as dist name originally chart and now
App-Chart.
(Still available the old Chart in Scheme.)
