If you're having to ask, I say , get out as soon as you sense that .
It suggests you're not entirely confident with your technical approach (yet) used to find, and manage, trade ops.
Review what your exit strategies are , then execute them. If, once in a trade, you use a fixed stop to protect capital , and by extension manage market randomness, then leave the trade alone. But you should know that, and not be asking any, should I, or shan't I type questions. (although it's good you did for raising awareness )
If the trade turns and gives you a huge windfall, that will likely start reinforcing , set in motion, intermittent , unpredictable, undesirable trading behaviour, which ultimately will probably lead to even deeper feelings of uncertainty down the road.
Just my thoughts. And we all have to learn, so all the best with it.
Final thought.
What's more important to you ? Do you want the trade to be a winner , or do you want to know you did the right thing , no matter what the trade outcome may be ?
