NEW YORK (

TheStreet

) -- GBP/USD: With a halt in its decline on Tuesday and a follow through higher in early trading today, further strength is now expected.

Note that the pair continues to trade within its range suggesting that its present attempt on the upside is not a full-fledged rally.

On further recovery, the 1.6138 level will be targeted with a loss of there turning focus to the 1.6265 level and then the 1.6397 level, its March 22, 2011 high.

Further resistance comes in at the 1.6455 level followed by the 1.6720 level and next the 1.6877 level, its Nov. 2009 high. On the downside, below the 1.5935 level will resume its weakness started from the 1.6397 level toward the 1.5819 level, its Jan. 19, 2011 low and possibly lower towards the 1.5700 level.

All in all, though retaining its broader bullish structure, GBP looks vulnerable within its sideways trading range.
