Short-term market record: 1. First, assuming that Wave Y has not ended, the most common limit for Y3 is 1.618 times Y1, which is 75,131, and after a pullback, it may break out into Y5; 2. Assuming Y3 peaks at 74,100 and needs to break below 70,109 for confirmation, since Y3 has exceeded 1.382 times Y1, it may also break out into Y5; observe the depth of the pullback and the strength of support.
