In the range of 3000-3045, you may consider taking a light short position, with a stop loss set at 3100. For a light long position between 2830-2880, the stop loss should be set below 2800. In the current market, despite a certain rebound, caution is still necessary. The market remains in a stage of oversold rebound; although there are signs of recovery on the surface, there continues to be significant capital outflow daily. Until the key resistance level of 3150 is broken, even with obvious bullish signals, one should continue to operate under a bearish trend.
