If EZ economic data is positive: G/U rapidly comes back 1.658
If EZ economic data is negative: G/U falls down to 1.63 I show on the chart.
I ignore BoE Meeting next week because I don't see any change in of BoC . They will unchange the policy until they see they need to act.
I show on the chart: G/U respects pattern greatly, so you can SELL when G/U breaks the pattern.
I keep NEUTRAL view about G/U: I wait and observe.
