1, reckless and blind. Some investors have never studied investment theory and skills seriously and systematically, nor have they undergone any simulation training, and even do not understand the basic knowledge of foreign exchange, so they rashly enter the foreign exchange market to participate in investment. The rapid depreciation of their capital accounts will be an inevitable choice. 2. Fear of shrinking back. No matter how clever a person is, he will become stupid when he is afraid. In the securities market, fear often makes investors' investment level abnormal, often makes mistakes, and finally leads to investment failure. 3, impatience and progress. After all, to err is human. Because the situation in the foreign exchange market is unpredictable, investors sometimes get angry. This kind of anxiety is the taboo of foreign exchange speculation, which will greatly reduce investors' trading skills and lead investors to make irreparable wrong decisions because they can't think calmly. 4. Patience lacks psychology. Some investors can't wait. Once they enter the market, the exchange rate will move in the direction that is beneficial to individuals, preferably by a large margin, to realize the desire of getting rich overnight.
