Most news will shake up price and continue the direction of the trend.
I far as your statement, we can not rule out that there might not be a system that can detect the news.
I have seen a system that had a feed that could read market tension, seconds before the news release, it would take a trade as the tension was building one direction or the other............it had a positive win ratio..........
If you google for it, you might even find it still, I don't quite remember their name...........
Thanks for posting...........
