well, that's always happen everyday
dissappointed because sell at lower profit
but sometimes, it can be lucky because of sell at higher point
that's what you think because of not enter and exit market with good strategy
none gan always lucky with good entry and exit point
the point is, if you already make a decision, what is already happen doesnt matter
what will we do next is the most important thing
This is very common as you said but we can change this by being more patient and careful in trading. These two are very significant not to feel bad about you, not to get depressed, not to get disappointed with yourself in trading.
I'm trying to apply them.
