Consecutive bear bars. has recently been oversold in the 20 level area. So, Why wouldn't they be inclinde to make another push down there to see who else may want to sell. GB is still trying to stabilize after BREXIT, and since then the majority of action has been selling off. The market has inertia- it continues to do what it's been doing (in the bigger picture). GB leaving the EU is a devaluing effect for them.
