how to read bloomberg news into program?

Quote from black diamond:

I don't think the logic has to be all that sophisticated to have some value. Just the fact that a company has been mentioned in a headline is useful. I have seen academic papers that use news databases and show stocks with large returns accompanied by a headline react differently than stocks with large returns and no news, I am pretty sure I can find them if anyone cares.

would be interesting to have a look at these papers even if it looks to be grossly oversimplified approach...

Here is some code from my files. It is c# code that might read data from the web. It sounds similar to what you want.

I think the paper you mentioned is very useful. I am very interested in the result.

when these is regular economic release, as too many people are watching them, the stock price will react very quickly. For example, one can use excel or other program to read bloomberg ecomonic number in realtime. As too many people are competing, there is little profit left.

I think the chance comes from these unregular, or surprised news release.

meaning that you need to define in advance what these unexpected news will be.....which can be a hard thing to do because they will be unexpected after all...:)
 
Even trading the news with automation has been done for years. The word "buyback" in a story instantaneously generates buy orders. Look at the tick by tick data on story stocks. The stocks are bought (or sold) to higher (or lower) levels before the human mind can comprehend a story.

that's assuming the people buying didn't already have the information before every one else.
 
Here are the papers. It has been a while since I read them, but from what I remember speed is not a huge issue, there is some long term over or underreaction. Also, I think they don't parse the news, they infer the content from the market reaction or something like that.

No problem. If you look up the Chan paper in Google scholar it will give you a list of all the papers that reference it.
