GBPUSD broke and closed above a solid horizontal resistance cluster on a daily time frame last week. The pair is correcting now. The market is steadily falling within a bullish flag pattern on 4H.
To catch the next bullish move, I would recommend waiting for a bullish breakout of the resistance of the flag. 4H candle close above will confirm the violation.
A bullish continuation will be expected at least to 1.25 then.
If the price breaks a support of the flag, the setup will become invalid.
