Everybody wants to do the same as what you describe but people have different sentiments over these and being a trader its something you just can't overlook. If people are willing to sell and get the profit they've been waiting than regret not selling and watch it goes back to where they started is much painful. Profit is Profit. You have to see the market as what the majority is thinking not just yours.
I agree with you
We dont have the right to judge traders desisions because everyone have his own trading strategy...even the one who sell with loses can maybe have reason in the end
