In the bigger picture, there is no change in our bearish view. That is, medium term rebound from 1.3503, which is treated as a correction to down trend from 2.1161, has completed at 1.7043 already. Fall from there is tentatively treated as resumption of the down trend from 2.1161 and should target a new low below 1.3503. On the upside, break of 1.5814 resistance is needed to invalidate this view. Otherwise, outlook will remain bearish.
In the longer term picture, the corrective nature of the multi-decade advance from 1.0463 (85 low) to 2.1161 as well as the impulsive nature of the fall from there suggests that GBP/USD is now in an early stage of a long term down trend. Rebound from 1.3503 should have completed and the whole fall from 2.1161 is likely resuming for 61.8% projection of 2.1161 to 1.3503 from 1.7043 at 1.2310 next.
