In the short term, the currency pair registered a temporary rebound which represents a downside continuation pattern.It’s traded at 1.3384 level right above 1.3374 today’s low. The bias is berish, so more declines are favored. The rate ignored strong downside obstacles signaling a potential drop towards new lows. As you already know, the USD rallied after the FOMC. It seems that the Federal Reserve could start hiking rates in March when they will end the pandemic QE.

It has retested the 38.2% retracement level before resuming its corrective phase.Now, it challenges the 61.8% (1.3385) retracement level which represents a static support. Making a valid breakdown below this downside obstacle may open the door for a deeper drop. You already know from my analyses that the GBP/USD pair could be attracted by the median line (LML) after stabilizing below the median line (ML) of the ascending pitchfork.In the short term, it remains to see how it will react around the 61.8% level. We cannot exclude a minor rebound after its amazing sell-off.
