GBPUSD and failing to make a higher high rule

Victor Sperandeo's rule

The GBPUSD fulfils one of the golden rules used by the legendary trader right now. Here it is:

In an uptrend, if a higher high is made but fails to carry through, and then prices drop below the previous high, then the trend is apt to reverse. The converse is true for downtrends.

Nice little rule and 1.3740 circa is the 'I'm wrong' level. Previous high broken as price retreats lower.
