What is the essence of trading? First, set your stop-loss properly. Although it may feel regrettable, trading must be accompanied by a stop-loss; otherwise, in a one-sided market, you could be wiped out overnight. Accept the blame from followers, but at the same time, I hope all traders and investors enter the market with a stop-loss, especially in contracts. Small stop-losses for big gains—that's the original intention of trading contracts.
