Thanks...but...
How would I use that to prove to someone that wants factual evidence that today's tweet by President Trump impacted the market performance in the S&P 500 ?
I'm being funny by the way when someone ask for factual evidence although I believe one day there will be legitimate studies to prove such regardless to the fact that I was watching real time news when the tweet hit the market and then I saw in real time how the market suddenly (understatement) reacted to the tweet although there was an outside chance the other guy in the debate that stated it was "pure TA selloff"...nothing to do with a tweet.

The point of my reply is that you can get machine-readable news, feed it into an algo, and have it make trades for you based on the incoming messages, like Mr. Gumby stated. You have to pay for that data feed, but it is there.
