here, we have structure forming an ascending triangle, as you should it indicates the probability we could a trend back down! lower than it created support !
i) This is not a signal or financial advice
ii) Compare with previous chart patterns
my analysis is based on pattern as an indicator, take note; it's likely we are going to see GBPJPY continue BULLISH, forming this old textbook setup i'm somewhat convinced this pullback( exhaustion from the pound rally, though we know this Pound is struggling since the last Brexit update! )
The USD day by day shows lack of moment and after a push up by counter market, a retracement for a bullish trend for stronger currency like GBP and Bearish trend for weaker currency like CHF
