Add Stock Screener Support #17

Closed GoogleCodeExporter closed 9 years ago

GoogleCodeExporter commented 9 years ago
Hi Maas,
I've already implemented such a function some years ago (2007), and today I've 
tested and it works ... Maybe it can be re engineered and integrated into your 
library.

So basically you can search the top gainers, losers, ... to write this, I've 
used an http sniffer and watched how the java version of the Yahoo Screen 
composed the request (http://screen.finance.yahoo.com/newscreener.html).

Attached you'll find the still working function I wrote.

Let me know

Regards,
Angel

Thanks for the hint! 
I will have a look at it, but not for next version (0.8.1). 0.8.1 is nearly 
completed and I will release it today or the next day.

Is there any documentation now about reports.finance.yahoo.com? 
(maybe they created one since 2007; I'm not very confident, but asking a 
question costs nothing ^^)

we can try ...
but, in any case, take a look at the online screener, it's a good starting 
point (and there is a bond screener, a fund screener, ... too)

Regards,
Angelo

Hi Angelo,
I implemented the Stock Screener now. Please check out new version 0.8.3.
Maybe you can test it that it's OK.

First Bug I've found: If you use a criteria which uses a stock property that is 
not default (ID, Name, Price, Date, etc. -> StockScreenerResult) the response 
has more than the default properties. E.g. P/S criteria -> additional P/S 
property.
I think I will use QuoteData as result instead of StockScreenerResult.
