As we can see on the 4H chart is that GBPUSD formed a double bottom and went up which we call wave 1, we can also see that price is forming wave 2 which is a retracement move. The resistance is @ the neckline of the double bottom and that is where we will enter since wave 2 will be completed at that level. We can also see that GBPUSD formed a triangle and broke it which means the price will go up after the retracement.
Thus buy GBPUSD @ 1.30700 or 1.30800
Tp @ 1.33000
