i am looking as well considering trade the news, fly on the wall and Benzinga. They all seem decent, hard to tell what the best one is unless comparing news release timing to chart movement. Also looking into twitter feeds as the (HFT's) are the first ones to get the first few nibbles.
As a futures trader, I use twitter and stocktwits real-time keywords as a real-time news source to help with understanding the "market context" of whatever I'm trading. Not sure what you meant by "twitter indicators" and not sure what you meant by trading off of them. Therefore, please clarify.
Stock twits is filled with people who are "never wrong". I am looking for a breaking news site. those are good but nothing really fast. Will keep looking and update people if I hear of anything
Also, just trying to find one site that has most of all of those sites combined, tired of having around 8 pages up of news and info
