This is usually the case. A wave of futures market often begins with a rise. At first, the increase was not big, and there were not many followers and participants. With the gradual rise of commodity futures, there are more followers, the profit-making effect is gradually enlarged, more and more participants are involved, and the positions are gradually enlarged. Later, the futures rose to a critical point, and the bears could not bear more losses and began to cut their meat and leave. The bulls began to close their positions, and the corresponding profits were settled, and the price began to fall gradually. Because the bulls can't find the right opportunity for the time being and don't participate for the time being, the number of people who follow and participate begins to decrease, and the transaction begins to become light. Then gradually reduce the position.
