This chart mostly speaks for itself. GBPUSD has been looking to break that resistance line at 1.43 and has closed above that on the 4H. Look for the retest and then get set to enter this pair because it hasn't hit this mark since February of this year (and had candles close below where it is now).
Other market indicators are also suggesting this pair goes long, so at a glance, this pair should continue on the uptrend.
Outlook is very long, very positive and it wouldn't be a bad idea to make a long position very soon.
REMEMBER: This has not been a very common analysis for this pair, most people say this trend will change to bearish on this pair.
