The GBPUSD is supported by a long term trendline that dates to 1985 (see purple line at bottom of chart).
I expect a larger bounce off of this line, regardless of the larger trend. Measured support from the 100% of 2.1166-1.7443/1.8675 reinforces the long term trendline. Similar to the EURUSD, a triangle could unfold (in which case the GBPUSD would remain below 1.6679) before a drop to a new low a larger recovery.
