GBPUSD Retracement? 21.09.2021

OANDA:GBPUSD   British Pound / U.S. Dollar
It is clear that the pair has been suffering a long fall since the 16th of Sept.

The Fibo retracement looks promising and further fall is unlikely without a retracement first at least where the blue arrow indicates.

No significant news/reports for the GBP or the USD to push the pair further down are scheduled so probability of upward retracement is on our side.
