Keep on knocking and they'll eventually let you in
Cable is down 63 pips to the low of the session at $1.3765. That's the worst level of the week and it will leave GBP/USD just above the cluster of lows that stretches down to 1.3731.
If that gives way then the March-April double bottom of 1.3670 is the next stop. If that can't hold then it could get ugly fast.
What's worrisome is that the selling comes despite a hawkish turn from a pair of MPC members.
