4If the purchased item is in a balanced and volatile trend, there is no need to immediately stop the loss, just patiently wait for it to enter the high point of the volatility cycle. When the situation is resolved or the loss is very small, there is no need to be greedy to immediately exit.
5If the purchase is in a downward trend, once it is confirmed that the downward trend has formed, the loss should be stopped immediately and there must be no illusions. Any hesitation or hesitation may leave investors with no way out.
