It can happen and yes - with price testing 6850 this may well be a pre news set up - ie take price higher before the news - as many traders do not trade an hour or so before and then when its up 20 -50 pips higher - then sell like crazy - dropping price 50 -100 pips.
The FX market is a big money game - and players need to take money off all other traders to make it all worth while to them.
Therefore the "game" will be one of deception along with twists - false information - false directions - etc etc - anything to get you in trading the wrong way
To intraday trade and to catch the continual changes - beside technical and fundamental analysis you need to be aware of what I call "gameplay" - ie false sentiment and how the market can set you up to be caught out.
News Items can be great examples of gameplay at work.
For me now - I a already scalp selling the GU under 48 - although expect 37 -39 to hold again before the next twist
If we drop under 6830 - well that shows the rise to 50 - was really a false move just to trap some bulls in buys
