Many people have lost their positions when the price has returned.
Including me, today's decline has caused a lot of stop losses in contracts.
Why stop loss, not technical aspects? Isn't it awesome? Technology is emotionless, while trading is human nature, and human nature is often invincible. If you enter the left side too early, the position will not meet your own judgment and expectations after replenishing the position, so you have to cut your losses and leave.
Still need to learn... and practice~
