NEW YORK (

TheStreet

) - The GBP-USD pair remains weak and vulnerable within its established sideways trading range. Further weakness could be developing towards the 1.5976 level.

We expect a halt in declines to occur at that level if tested. Further down, support comes at the 1.5819 level, its Jan. 19, 2011 low.

Its daily RSI is bearish and pointing lower.

On the other hand, a return above the 1.6397 level must occur to reverse its present bear threats. This will clear the way for a push further higher towards the 1.6455 level followed by the 1.6720 level and next the 1.6877 level, its November, 2009 high.

All in all, though retaining its broader bullish structure, GBP remains trapped in a range.
