if only watch the small bullish channel , then price perhaps have more room further above 0.78; however if you open a bigger picture in the daily chary, there is a triangle is forming and the last two days price kissed the upper bond and rejected there, as well clearly two inverted hammer daily candle indicate that there is strong sell signal appeared. so i suggest sell current level, with SL above 0.7760.. target will depend on the Fib retracement level plus two uptrend line support. they are around 0.7560 and 0.7450 respectively, trade may run 4 weeks around..
Cheers and GL
