If you are a technical trader I would personally leave the cable alone for a while.
I work in a spread bet trading room and we are just seeing daily moves on cable strictly based around news comments, we just had a sqwark 30 mins ago that "Merkel has told EU leaders to close the door on back door negotiations on the UK until article 50 is triggered" Consequently the cable went down 40 ticks.
These sort of things are happening daily and they often have much bigger moves than that.
There's nobody really buying cable at the moment and big institutions are predicting eur/gbp parity by next year.
Stay away from cable or be prepared to be dinked on regular noise.
