PostPosted: Sat Jul 07, 2012 3:30 pm    Post subject: Stock Monitoring Program Reply with quote

Hi there, do you guys know of any stock monitoring programs in the base portage tree? or maybe even in the more common overlays?

I'm looking for some sort of program that would allow me to look at how selected stocks evolve outside of a browser. This one seemed like exactly what I'm looking for http://www.grism.org/index.html - but it's got neither an ebuild, nor has it been developed for quite a few years. I don't really need the application to have trading functionality embedded, I'm just looking for something to keep a nice overview of some stocks.

So, any ideas?

I wrote my own software for this purpose, using matplotlib. If I had infinite time, I would polish it up and release it as an open source toolkit.

so you weren't bothered by the fact that apparently nobody picked up on this niche? Quite frankly I'm surprised - especially seeing that programs (with HORRID interfaces) which can do that + trade sell at 20€/month.

Anyway, I may have gotten lucky - matplotlib is one of the few things I use for programming - could you maybe share that program with me? or upload it to github? I may polish it up for my personal use which would increase its user base by 100% ;)

It doesn't surprise me that open source people aren't interested in stock market analysis; or, if they are, they keep it to themselves :P

I need to organize my code and remove my proprietary stuff before it's fit to release into the wild. Ideally, it'd be nice to have an open source toolkit for various technical indicators and charting methods, a la StockCharts.

Here's a nice demo of matplotlib's capabilities.

The real trick is to get data with a greater frequency than daily.

Code:
quotes = quotes_historical_yahoo('INTC', date1, date2)
if len(quotes) == 0:
    raise SystemExit


So this is what fetches the data from yahoo? Seems simple enough - now what'S your trick for doing this in real time?

I have written a near to complete program 20 years ago based on MS-Access and MS-Basic
Then I realized it was near to impossible to get reliable intraday data in real time without either paying for or registering with some serious broker.
Then I realized that registering with some serious broker, you are offered so many ready made intraday analysis that your screen just cannot display all of them.
Then... I understood why traders are working surrounded by several displays, threw my program away and wrote a much simpler one :
Code:
Section "Device"
    Identifier  "Card0"
    Driver      "nvidia"
    Option     "TwinView"
EndSection

:D

Hey, I don't trade stocks at all, but I do air conditioning repair at several trading floors, 1 a bank investment group, another our provincial electric power company. Those people have a minimum of 4 monitors, most have 6 - 24 to 37 inch (2 high, 3 wide) monitors, with 2 or 3 computers each running them and their data feeds.

Then there are the big screen monitors with other data, news feeds, etc. scattered around the floor...
