GBPJPY trades inside triangle, waiting for breakout

For the past six weeks, GBPJPY is trading inside a symmetric triangle (red and blue lines). The last few days have brought upon constant pressure on the upper line of the formation (red). Together with this dynamic resistance, we have a horizontal one on the 167.3 (orange).

The price action here is pretty simple. GBPJPY breaking the two resistances and closing the day on the green rectangle or higher would be a great mid-term buy signal. On the other hand, the price bouncing significantly with a bearish rejection pattern would be a nice signal to sell. In my opinion, the first scenario is currently slightly more probable, so hunting the breakout with a buy stop order sounds like a very interesting idea.
