After the order is locked in, as long as it is not sold, it cannot be considered that the investment has lost everything. If the order in hand has development prospects and the investment environment has not deteriorated, and the market situation is not yet clear, it should remain calm and wait for the price to rebound and unwind. It should not be blindly sold. When the market is clear, unwinding the counter trend order is equivalent to cutting off the source of loss. But it should be noted that a counter trend order does not equal a loss order. Another opportunity is to choose whether the market has stabilized or not.
