Its A head and Shoulder if you graph the chart on a Daily Basis

The chart draw a head and shoulder pattern after inverted Head and Shoulder last February to April. Waiting for good News on GBP tomorrow. Since this is overbought, it needs to be breath around -15% to -50% (a nice entry for uptrend). beware of FED Announcement because this are main things that GBP become bearish. BREXIT is a bullish trend for this. Happy Trading.
