The GBPUSD chart is creating a DOUBLE BOTTOM PATTERN pattern which indicates a bullish trend. This will be confirmed once the 1.23200 level has been broken. A conservative approach (TP1) would be about half the size of the pattern, which is approximately 30 pips. An aggressive approach (TP2) would have us looking at the full size of the pattern, which is approximately 60 pips. Thus, the trade is executed as follows:
GBPUSD
BUY STOP: 1.23200
SL: 1.22600
TP1: 1.23500
TP2: 1.23800
