From a technical perspective, the moving average system still maintains a standard upward divergence structure, providing multiple levels of support for the price. The daily chart's pullback is mainly a process of testing and confirming support, aiming to gauge the strength of the bottom support. Currently, the candlestick pattern remains a typical bullish structure, and the upward trend remains intact.

Focusing on the four-hour timeframe, today's movement closely aligns with our expectations. After the price retested the low of 71,700 in the afternoon, it quickly stabilized and rebounded strongly. The key support zone below is above 71,400, which is consistent with our intraday assessment of the bottom support range. After this round of retesting and confirmation, the lower boundary support of the oscillation range has been effectively validated, eliminating potential risks for subsequent upward movement. Meanwhile, the Bollinger Bands indicator continues to show an open-mouth formation, indicating that after consolidation, there is still upward momentum. The overall trend remains steadily within the upward channel.

In terms of trading strategy, the overnight outlook remains unchanged, with a focus on long positions. Since the retest has basically confirmed support is effective, any pullback near the support zone is a good opportunity to establish long positions. It is recommended to rely on the confirmed support area of 71,400-71,700 as a defense zone, and to enter long positions when appropriate, targeting the intraday high and resistance levels of the upper channel.
