GBPUSD is now trading around 1.36. At 1.3580-1.3620 we find a resistance zone that was once support. Price has tested this zone several times from above and now that price had broken below it, we see a back test of this zone to confirm if the breakdown was real or a fake one.

GBPUSD has made a strong upward move from recent lows at 1.3410. Price has now retraced 61.8% of the decline from 1.3749. At 1.36 where we find the 61.8% Fibonacci retracement, we consider this an important Fibonacci level. We usually see reversals around the 61.8% Fibonacci retracement, therefore a rejection at the 1.36 level, combined with the fact that this is horizontal resistance as well, will make us expect another sell off to push price towards 1.34 again.
