Where next for GBP/JPY?

The GBP/JPY used to be known as the Beast of Forex as this was a pair that frequently moved 200 to 300 pips in a day in either direction. For the last 4 weeks this pair has been the Lamb of Forex. 4 weekly doji indecision candles have formed in the last 4 weeks and price has gone from 140.04 to 139.65 - a mere 38 pip move. Even the surprise hawkish note emanating from the MPC failed to shake GBP/USD out of its torpor. The flag formation that this pair is held in remains and a sustained break either side will be significant. The look of the DTF is BULLISH and the TDI is quite BULLISH on this time frame. Above 140.52 strengthens this view.
