Expanding wedge or triangle pattern on the GBP vs the JPY with a butterfly 🦋 type of shape. The pattern seemed to begin with a year up on on balance volume and then a year down. Followed by 2 years up and 2 years down. Then three years up. Now you would think if the pattern holds it will begin a three year period down on OBV. It seems clear that this currency pairing will experience great volatility going forward. Go short on the way down and long on the way up. If it breaks out of the triangle that means something else is happening. Exact values and times are not possible. This is just a guess based on a repeat of the fractal but in a larger pattern. It could be a reverse symmetry move which would change it slightly.
