The so-called H clients have led to the fall of the entire market. Currently, the overall market sentiment is in fear. However, since the drop from around 3914 at 8 AM yesterday to today’s lowest point of 3476, the decline has reached over 430 points. Although all levels are currently in a downward trend, a continuous decline will leave the market lacking in bullish traders' catch a falling knife. Therefore, even if it continues to fall, it will be a volatile downtrend rather than a constant plummet. So during this period, there will be market rebounds. Just like yesterday, even though the market showed a decline, I made money from the rebound. The support level at 3450 is a relatively important key node. Of course, although our order at 3475 missed by one point, I still firmly believe we can see 3600 and 3680 above. Therefore, in the current situation, one can adopt a quick trading strategy to go long.
