noob question - best way to detect if news is affecting a stock?

Trading is part art, part science -- you'll never truly, ultimately know what moves a stock or the market. :):confused:
That's part of the mystique and skill...of trading,

Hi Guys,

First post so go easy please ;-)

I'm an experienced software developer with some time on my hands now and I'm looking to create a free system that will detect stock movements and then check pretty much every news source that can be checked online for news regarding this company. So that's blogs, social media, news websites etc. With the aim of getting this information to the user as quickly as possible.

At the moment I'm not sure whats the best way to detect that something might be effecting a stock, I was going to go with just the price of the stock but then I thought some news may be interpreted as good to some and bad to others so the price might not actually change much. Then I thought of checking the volume of the stock over a short interval. I saw some websites do offer this but it appears they don't show "out of hours" trading volume. Is that correct? If not can someone point me in the direction of one that does?

What stats would you guys recommend looking at to detect "interest/purchases" and where is the best place to source these stats/figures?

Any help at all would be greatly appreciated :)

Thanks!

There is no simple plain algorithm allowing to find what affects every stocks unless you have huge computing facilities to assess tons of information. so I guess you will need to analyze every company for its own news, resources etc. But basic method is to analyze twitter, their CEO or executive accounts, media like bloomberg etc. and other similar resources.

Can you remember the website out of curiosity?

I say +1 to what neke said.

Wild goose chase, up a creek without a paddle, needle in internet-sized haystack, whatever you want to call it...

I remain unconvinced about your understanding of the exponential challenge you are taking on, and therefore no, I'm not giving you the website address because you've got an Everest sized mountain to conquer and you've said/done nothing to convince me you're even wearing the right boots.

Furthermore, the lower down the caps you go, the more gibberish nonsense your system is likely to spout out. Show me something on that on the well-covered mega-caps (e.g. the FANGs of this world) that works reliably (i.e. if the false-positives / false-negatives are not consistently sub-1%, I'm not interested) AND consistently AND does a better job than any of the paid services out there (including Bloomberg/Reuters) in getting the news to people "first" (i.e. if another paid service is consistently quicker, then there's nothing special about yours) . Then we can start talking about interesting websites for mid-caps and below.
