$GBPUSD- a little more room?

We currently have broken out of the upper trend wall in a downtrend on the cross.  We have tested the 1.6180 resistance three times.  If it breaks to the north look for initial resistance target @ 1.6217 – should see sellers here. A move to the downside here favors a move back to the r2 @ 1.6070 since it is a square up day on Friday.
