Currently, the big one is still maintaining range-bound oscillation, with an overall pattern of pressure-driven pullbacks and bounce-offs from bottoms in repeated swings, lacking continuity in both rises and falls.

Under this type of price action, swing trading is not suitable; short-term quick entries and exits are more appropriate, accumulating positions and rebuilding confidence through flexible operations.

The overall market remains weak currently, and subsequent strategies will continue to focus on high-altitude (shorting) ideas within the range.

For the big one's subsequent rebound, 71,600-72,100 southward, with a downside target of 69,000-68,500 in view.
