The key to this wave of market行情 lies in two defensive lines. First is the 18 level, which can be considered the first support—once broken, the probability of accelerating downward increases significantly. Below that, there is a second support point around 15.5. This line is very critical; if it is broken, this行情 will basically be over, so it is generally unlikely to be broken easily.

Based on this judgment, the first take profit is set at 18.1. When the market weakens further, the second take profit point is placed at 15.4. It is worth mentioning that if the price retraces to 15.4, you can consider entering a small position long to try for a rebound.

But the market is like this; sudden changes are unpredictable. Timely take profit and stop loss—no matter how cliché it sounds, it remains the truth. There is an old saying—if Heaven does not give, it will take revenge. If you cannot secure profits in time, the market will naturally arrange a stop loss for you; if you haven't set a stop loss properly, you can only become fuel for the market.

Be cautious, always be cautious!
