GBP/JPY has been falling since it rolled over at the September 2 high. It has now probably begun a new short-term downtrend, reversing the previous August uptrend.
Most recently it bottomed out on September 6 and pulled back. It now seems to be falling again, perhaps resuming its dominant downtrend.
In technical analysis theory the odds favor an extension of the established downtrend, which suggests further weakness as the short-term trend unfolds.
A break below 186.51 (September 6 low) will confirm further downside towards the next target at 184.51 (August 8 swing low) followed by 182.82 (August 6 swing low). The ultimate downside target is the August 5 low at 180.06.
