Quite agree with you. News as it self is unexpected thing so that's why we use risk management and money management practicies, they include such unexpectedness of news, you know. I guess that every trader must follow economic news majorly, plus in dependance on the preferable asset we can add here political news, because it also affects currencies prices and assets prices.
Moreover, if a trader tends to trade such assets which are connected with green economy, he also must monitor such kinds of news, anyway everything closes in economy. Economic calendar is created to help traders I believe.
I feel that it is only some really serious kind of news that you should pay attention to while trading like NFP, OPEC and something like that. Minor news are really difficult to follow and it is also difficult to estimate.
