The key short selling points of 71500, 71300, and 71000 over the past three days have basically been accurately predicted.

However, it's a bit of a pity that for 71500 and 71000, I only managed to take the initial position, and for 71300, I was still hanging at the 71500 price level. In the end, I missed the transaction by two hundred points. The rhythm and direction were correct, but it's a bit regrettable that I couldn't fully take the position.
