1. First support 27,750–27,800 (currently being tested)

Recent intraday swing low; a short-term lifeline. If the daily chart effectively breaks down, downside room will open.

2. Medium-term support 27,450
The starting point of the rally that began in April; an important area of dense holdings.

3. Strong support 27,000 (near the 200-day moving average)
The core defensive line for the bulls in this bull market. If it’s lost, it means the uptrend over the medium term is over.

Resistance (rebound obstacles)

1. First short-term resistance: 28,300–28,500
The prior breakdown’s high-volume, dense trading area; the first checkpoint for any rebound.

2. Medium-term resistance: 29,000–29,200
A cluster of multiple moving averages. Only if price can rise with volume and hold above this level does it become possible that the pullback ends in phases.

3. Strong resistance 29,700–30,000, the starting zone of this correction
Caught in a position tonight—spring up fast.
