It's true I agree with you, this issue has even been emphasized many times but there are still many traders who without realizing it turn out to be greedy. Usually they will always feel dissatisfied with the targets that have been set from the start so that they rashly without thinking in the middle of the trip they continue to increase their targets because they see the market continues to rise, but unfortunately the market finally drops again even though they have not had time to sell it. As a result they have to waiting for the market to come back up.
