80,500 is the short-term defense line, 77,300 is the medium-term defense line, and 75,200 is the trend watershed. Currently in the overbought zone, the probability of a short-term pullback is not small, but the medium-term trend structure has not been broken. If you want to find a more secure entry point, the area around 77,300 may be a more cost-effective support zone during the consolidation phase.
