My view is balanced on whether the resistance is broken or not (orange line):
There is a higher probability that price moves lower from this resistance based on history since Dec-16. However, if price moves above 1.25 and holds (i.e. consolidates) for a few days its a sign that support is being found at 1.25, buying is building, and GBP/USD is poised to break through 1.28.
Conclusion: hold until we enter Key Zone. If already long, take profit and pause; don't risk a pullback to the lower resistance.
