invest applet MACD is incorrectly displayed

[ex-oficio]

Binary package hint: gnome-applets

using Ubuntu 9.10 karmic

gnome-applets:
  Installed: 2.28.0-0ubuntu2

currently, the MACD indicator is displayed as two histograms, one for the MACD and one for the "signal line". this is incorrect. the MACD graph should be presented as two lines for the MACD and signal, and optionally, a histogram to show the difference between the two.

the wikipedia page here shows what i mean:

http://en.wikipedia.org/wiki/MACD

It took me a while to work out what was going on with the macd on this applet, and currently the information which this indicator is supposed to convey is often hard to read.

i really like this applet and find it much more convenient that anything else available, but this is letting it down IMHO.

best regards,

Enrico,

Thanks for the response. i knew the data came from yahoo, but i didnt realise the charts were generated by yahoo directly.

It's an odd way to show the macd data, and ive never seen it before. its not very easy to read it. I will see if i can generate the MACD in the conventional manner directly at the yahoo site, and let you know if so. i couldnt do it when i tried a few moments ago, but i dont have much time now, and will try again later.

again, thanks for your response,

regards,

ex-oficio.

hi,

apologies for forgetting about this.

i have just had a play trying to see what is available.

as suspected, it seems its not possible to influence how the macd is displayed on a particular server.

the ichart.finance.yahoo.com server seems to be the better option though. even though it doesn't look as visually appealing, the signal line is visible, and where it cuts the macd columns it does sort of create a MACD histogram of sorts. this one at least does provide the information one would need if they were trying to see the macd.

to re-use that example you gave, the chart below demonstrates this:

http://ichart.finance.yahoo.com/z?s=JMC.L&t=6m&q=l&l=off&z=l&p=m20,e5,e20,b,v,&a=f14,w14,m26-12-9,ss

some people might not like the look of this graph though. i would suggest the best thing would be to allow the server to be chosen from a combobox in the preferences.

what language is this written in? i may have time to do this over the next few weeks.

regards,

lately the charts do not open in invest applet.

i cant remember where i found this now, but I can report that you can get the invest applet to display a chart by editing

/usr/share/pyshared/invest/chart.py

and changing line 209 to remove europe from the base chart url:

i commented out the original and replaced it with the changed line, as in this snippet:

  #chart_base_url = "http://ichart.europe.yahoo.com/z?s=%(s)s&t=%(t)s&q=%(q)s&l=%(l)s&z=%(z)s&p=%(p)s&a=%(a)s%(opt)s"
  chart_base_url = "http://ichart.yahoo.com/z?s=%(s)s&t=%(t)s&q=%(q)s&l=%(l)s&z=%(z)s&p=%(p)s&a=%(a)s%(opt)s"

the graph doesnt look like the old one. apart from the fact that it wont show trade volume, its a better graph, especially the MACD.

sorry i couldn't find the bug for graphs not showing.
