Gbpusd has made several tops at 1.3440$ and reversed to 1.3250$ currently. The fall was initiated by draghi , the head of ECB lowering growth forecast from 2.4% to 2.1% and keeping interest at all time low.
Brexit negotiations are ofcourse the main blame or fame for any move in Gbp/usd
Technically speaking , 1.3250$ is very important support for the pait and if broken , the pair will be terribly bearish and might head towards 1.3080$ area .
On the upside , 1.3340$ is a tough resistance for the pair .
