In fact, anyone who sees the benefit is trying to see that the benefit I get is enough, and when someone sees the loss, he thinks that I have taken something high in price I don't want to sell, so he waits for it to go up, or go to his buying price, or he will book a little profit, so he will sell it, that's what he intends. It is obvious that no one will sell a thing cheaply if you have bought it at a high price, so it is a good practice to never sell anything in loss because it's reality that if you are doing loss every day then future will be dark.
It true that it's never advisable to sell at loss but that's for people trading with the plan of long term buying and holding.If one must sell in profits then leverage trades are not for them as it might liquidate the fellows funds entirely that's why stop loss is important. But some new bies would always want to get involved cause of the profits they see online from exparts which isn't healthy.
All what we are delibrating is just how we can cut our loses though loses is part of the game.
