GBPUSD is likely to continue rallying next week, considering the spinning top bar that has formed on the weekly time-frame at the support at 1.2770.

By the end of NY session on Friday/Saturday in my opinion It's most likely to close below the current key resistance

GBP/USD rallied sharply this week and it reached a high at 1.3200. Since the pair is so bearish, I think the move to the upside will reach the last high at 1.3266 and if it breaks out above it will keep climbing to 1.3310, which is the MA89 on the W1 time frame.

GBP/USD broke out above the resistance at 1.3310 which is the MA89 indicator on the W1 time frame. After such a breakout the rally will most likely accelerate, I think next target will be around 1.3450.

GBP/USD rallied hard after the BoE news on Friday. It broke out above 1.3500 and continued climbing. I wouldn't be surprised if the pair eventually reached 1.3700.

FOMC will be announcing the US Federal Funds rate this week, so expect a lot of volatility on all USD-related pairs, GBP/USD included.

The news caused a significant drop, but the pair remained within the range between 1.3460 - 1.3700 and it looks like that range won't end before the market closes today.

GBP/USD - As it seems it is a "dollar day" most likely the price will move down to 1.3415/20. The contrarian may like that levels for some scalps from the long side of the market

GBP/USD rebounded from 1.3340 despite breaking out below the support at 1.3375, which is the MA89 indicator on the H4 time frame. I think the pair will retrace back to 1.3450 - 1.3470.
