Forex market always move with sentiment and that sentiment can depends on various factors happening globally, and there can be short term rumours on tops and bottoms and beleive me they do work only in the opposite directions once the storms settled.
I have seen few of those moments in recent time and huge gap in strong downtrend in Euro when first round of French election ends and results were to be published on Sunday whe Forex markets were close and we see few more spike following the start of new uptrend when price consolidates for months after "Brexit", vote last year in June 2016.
In those election momemts, nobody believe the majority but Forex market already was ready for shock as we already witness move from lows of 1.0490 to 1.0750, and till date Price has moved upto 8% in two weeks and the fact is beleiving the facts not rumours.
Few more things we need to know about the market that we must understand that price is random in nature and it has nothing to do with past and history, but logic and synchronize moves does help traders to sight setups that requires low risk.
Believing in patterns is the real mistake as every move is unique in nature
It might seems strange that as if every move is different and price react differently by pip and ratios but our mind has to be trained to view what is happening on charts rather than assuming what might happen if an area is breached, as move depends on action move and then reaction as series of events constiutes a movement
