Last night's market first dipped and then rose, dipping to around 83800, before the bulls made a strong push to rebound, reaching up to about 86800. The daily chart ultimately closed with a long lower shadow bearish candle, with important support needing to be focused on the 82800 area; on the four-hour level, short positions' volume has contracted, showing a two consecutive bullish candle pattern, with resistance focusing around 87300. Overall, the dominant trend led by short positions has not changed, and the current market is merely a phase of rebound correction, so operations need to be cautious of the risk of a drop after a weak rebound.
