GBP/USD is trading close to 1.3600 amid Brexit optimism. The UK Parliament is said to approve a Brexit deal on Dec 30, according to media reports.
From a technical perspective, the momentum seems strong enough to push the pair further beyond the 1.3600 round figure mark, towards testing last week's swing highs, around the 1.3625 region. This coincides with the top end of a three-month-old ascending trend-channel, which if cleared decisively will awaken bullish traders. This should assist bulls to aim to reclaim the 1.3700 mark for the first time since May 2018.
On the flip side, the key 1.3500 psychological mark might now supports the immediate downside. Bearish traders might now wait for sustained weakness below 1.3500. Any subsequent fall might now be seen as a buying opportunity. Failure to defend the mentioned support levels might prompt some technical selling and turn the pair vulnerable to slide back below the 1.3400 round-figure mark.
