NEW YORK (

) -- Having failed to sustain its intraday rally on Wednesday, GBP gave back almost all of that gain against the USD to close marginally higher and print a shooting star candle pattern.

This development leaves the risk of a reversal lower, possibly toward the Dec. 20 low of 1.5496. Below here will call for a run at the 1.5410 level with a breach turning focus to the Oct. 6 low of 1.5270. Further down, support lies at its psycho level at 1.5000.

Alternatively, the pair will have to break and hold above the 1.5779 level to prevent a resumption of its medium-term weakness. This will trigger further upside toward the Nov. 18 high of 1.5885 and then the Oct. 31 high of 1.6161.

On the whole, GBP continues to face corrective recovery risk.
