GBP/JPY continuation?

If you look at the Daily Chart, GBP/JPY broke the descending channel, and we know that whenever we see a break of a descending channel, usually the price reaches the beginning of the channel. Also, GBP/JPY broke the channel with 5 big waves up, and currently, we are in wave IV of big wave 5. Thus, I expect GBP/JPY to go up towards the beginning of the channel at 156.416 as our first target.
