As we all know already, it's better to be flat before important news, and sometime based on your trading style, it's even better to not trade during days that will have important news release.
I'm trading mainly USD pairs, so I look at the economic calendar for everything marked as high and i make sure that i m flat before the impact.
The problem with that is that we have a lot of days like this and I sometime (often) stopped trading for nothing because the news release didn't trigger any significant move.
My question is: concerning USD, which news tend to shake volatility the most? Any article on internet or something that cover all stuff related to news?
