GBPUSD 1H IDEA - Continuation Trend

I opened a position last week and hit TP1-TP2-TP3. Right now I'm looking for the pair to touch the trendline and see if it breaks or use it as a support to go to my TP4.
If it breaks - closing TP4 imediately and looking for selling oportunities
If the trend continues maybe open another buy position to secure more profits in the path to the TP4.
