GBPUSD Rise After Throwback?

As it is shown in the 4H time frame, GBPUSD is in an uptrend and has made a bullish structure with making higher highs and higher lows.

Moreover, price could break the resistance zone strongly and fixed above1.15 level.

Currently, the broken resistance zone has turned into the support area.

Price is in the exhaustion phase right now and it seems it is making a bullish flag pattern.

I expect a throwback to around the yellow support zone, then if there was any strong upside push, we can expect a rise on GBPUSD towards the green levels at 1.1680 and 1.1730
