Greed means excessively pursuing profits or unrealistic returns in trading. Sometimes you already have a good profit, but you are always reluctant to reduce or close your position. You always think that it will rise, and you will not take profit until it reaches xx.
As the price falls, you start to get anxious, why didn't I sell at that time, wasting so much holding time. This behavior is wrong, facing the profit, we should take profit in batches! Although it may reduce the profit in the end, it is always a good thing to secure the bag.
