EUR/GBP bullish breakout signal

We can see a bearish trend from dec till now but we see a flag pattern forming, so a breakout is possibly coming. Currently the market is going sideways so there is a lot of action building up. Wait the price to hit support level or break resistance. Than open 3 position with S/L on 0.8536, first T/P on 0.88, second T/P on 0.8878, Third T/P on 0.89575. When first T/P get's hit change the S/L on the remaining 2 trades to 0.88. Curious about your opinions!
