The GBP is the strongest currency of all the majors, although the CHF is not particularly weak. But the GBPCHF
pair has confirmed, with its low on May 19th, that it's following this up sloping fork. Short-term it's showing a robust up trend. If momentum is maintained, price is likely to reach the upper median line
parallel (a continuation of an Andrews' blue-to-blue trade) or at least the 100% level of the prior swing up.
