Alright, the market is moving quite standardly. Although each step doesn't have a strong impact, the direction of the back-and-forth route is actually correct. Continue to hold the short order; those who are holding can still go for 80, which was missed earlier. Now at 90, let's aim for 80 again to open a long order to hedge the profits. The strategy remains to go up to 4020 and then down to 3925; whichever hits first, we take that profit, and leave the rest. However, learn from the lesson: you must operate near the position by bowing to capital, and don't exceed ±5 points, otherwise, it won't make much sense. I won't bow; I must stick to the point.
