Whether in Forex or any other market: Inner trendlines = great launchpads on a break. Outer (peripheral) tend to hold more relevance on fades. Just another example here today that kicked roughly 60 pips before slowing down with a triple tap at the current highs.
The 100% extension target on this break is appx. 1.2576. Our current peak corresponds with another registered on May 29th.
