Intraday big cake has tested the 73500 support level multiple times and rebounded solidly. From a chart perspective, big cake maintains high-level oscillation with upward movement and steady rhythm. The four-hour level gradually rises with support from moving averages, pullbacks haven't effectively broken through the midline, only completing profit-taking with small bearish candles, with bulls dominating sentiment and strong buying interest below. The hourly line entered range consolidation after surging higher, with quick pullback reversals and rebound recovery. The daily line achieved consecutive bullish candles breaking through previous box resistance, with a clear medium-term bullish pattern. Focus ahead on whether the previous high of 75998 can be breached, with trend-following pullback dip-buying as the main approach.
