The pair managed to pull back strongly during Tuesday's session and now it's finding dynamic support at the 200 SMA (H1 chart). Further rebounds are expected and it should help to put the Cable on the bullish path towards 1.2600. However, today the UK PM Theresa May is expected to trigger Article 50 of Brexit and it can favor more weakness. MACD indicator is in the negative territory, supporting that scenario.
