the price is clearly coiling right now and waiting for some trigger!
here we have two equally possible scenarios:
bullish - on focus will be a falling wedge pattern. perfect confirmation to buy the pair is its breakout of resistance. to not be caught by a false violation I would suggest letting the market break a horizontal 1.66 structure as well. then buy on retest with your stop below the lower low within the wedge and targets: 1.6695 / 1.677
bearish - on focus will be a horizontal 1.654 structure. perfect signal to sell is a 4H candle close below the underlined structure. to avoid false breakout I would also let it close below the support of the wedge and then sell on retest. best stop is above the last lower high within the wedge and target 1.642
