Its probably just coincidence that the flatline coincided with the bilderberg meetings, the peak coincided with 500 euro and the exchange rate disparity is low on the euro side. Oh, and there's a small spike on days destroyed. Should be interesting to see how long it will need to flatline for a reversal and what happens when folks realise oil prices are about to make a move 

Oh, I'm sure there are reasons behind whatever happens. It's just so much less efficient to speculate about how to weigh them for each relatively minor swing that I'd rather not do so and instead look at the market metrics alone.
