GBP/JPY potential Long

can see that the gbp/jpy is respecting the green trendline on the one hour timeframe. If the price fails to break the resistance (rejects) i expect the price to touch the support zone ( the yellow triangle) and then bouce back up till the resistance.

However if the price manages to break the green trendline and testing the resistance, i would expect to go long once it retests back to the trendline that has now become support, untill it reaches the next resistance
