It seems GBPUSD now facing a trendline after a heavy bullish move. In Friday we had a rejection from this trendline with a bearish candle. Next week we may see a bearish movement with the first target at 1.5390 and the breaking of this level the 2nd target will be 1.5300. But the scenario will be invalid if it breaks the trendline above. So we should wait to see market reaction on Monday.
