Gbp will trade in the range until the 23rd and it will be prone to volatile moves on any poll data out of UK. Thant does not mean that you cannot position your self into the direction you believe GBP will head, hence if you are foreseeing brexit then you should short at supply and opposite for long play. I would be watching the present demand area for bullish
play. But is is Monday, the market is still digesting the news from last night.
