What do you mean by futures bear market → selling and opening positions → buying and closing positions?
Selling positions is bearish. Selling beans from a high point, such as 4300, and shorting soybeans means selling the opening price of 4300, and then the price falls. When it falls to 4200, you think it's time to rebound or rise. You can buy and close the position to hedge the original short position. That's what it means.
