Below is a good recap of an analysis which was conducted back in December 2020 [ A private idea, but has played out to perfection - reaching the weekly and monthly imbalance].
Below is the weekly Imbalances - where the Euro has provided a clean fractal point on the monthly imbalance back between 120.00 - 122.XX JPY. The Fibonacci sequence using a four day and daily chart showed the newly created imbalance was a pivot point at the 61.8 - 70.5% Fibonacci retrace zone. see [2] for further charts. Imbalances have a high probability for a retest which aligns with the monthly ray, where price will look to revert to for filling the wicks upon the four day fractals.
