What happens if/when cable breaks the December high

Cable has been testing it for the past hour
The pound is a handful of pips away from breaking the December peak and touching the best levels in six months.
The high so far in cable is 1.2772. That’s just shy the December 6 high of 1.2775. Oftentimes, big levels are tested and then the market quickly backs off but the buyers remain on the bid with cable holding at 1.2764. That’s a good sign of the bulls.
