Not being stopped out when DT?

I was wondering what kind of exercises do you practice to train yourself to stay with the profitable trade started in ie. 5min chart when at 1min you can see countertrend, and higher time frames still dont show other traders are going to join your position, but you know you are right, and it is true at the end. After few minutes a bigger trades are confirming your previous good trade but you are out.. . You were right, but not earned the money you wanted.

 

chart till you get an edge

but don't you even think about taking my edge

 

Exit half at a profit. Hold the remainder with a breakeven stop.
