The rapid rebound after the sharp drop has now arrived. Everyone should remember to lock in some of the profits if they did not reduce their positions before, in order to avoid the recurrence of extreme market conditions. Don't panic when the market falls and think about cutting losses. Most of the time, it is caused by too heavy positions. If the position is not large, the decline is a good opportunity to cover the position. At the same time, don't forget the days when you were beaten when the market rises. Control your greed so that you can have chips to buy at the bottom when others are panicking!
