Today Price action on German Prelim GDP q/q made me think, was that huge move predictable. No matter what direction, I just wonder was that possible to predict a size of move.

My general idea so far is that if there's no reason for price to change, it must bounce back. Price of EU was pumped up by risk appetite, so it must take some opposite movement to close all those positions. In other hand there was already couple of days since EU rocketed up, so there is a chance that part of profits is already taken and some sell pressure released slowly enough to keep price in place.

Recently however I started to consider, whether it is possible to predict big move on a news even if it's not exactly clear what is current market sentiment. 

Today Core CPI is tradable. 
I would be more happy to short EURUSD especially if it retrace to at least 1.3590. If it will not, I would predict short with possible bounce back up to that level [maybe even a bit lower - to monthly pivot level @ 1.3577].
