The support range in the above picture is 20715-2053, which cannot be narrowed down to the daily level for everyone to see clearly. In the past few days, you need to observe the trend of the market. If the daily level falls below smoothly, you must take profit or stop loss in time. In addition, the first two times in the price range of the low point (18***), there was a clear stop falling, and the situation of macd was the shrinking of the short side and the cross of macd respectively. Therefore, I personally think that the probability of a new low is not very high.
