In the downward trend, the stock price plummets or plunges away from the 10 moving average, which is a buying opportunity.

In the downward trend, the stock price runs below the 10 moving average. If the stock price falls sharply or continuously and is far away from the 10 moving average, the negative deviation rate of 10 is too large, which should be an opportunity for buying rebound, or even a mid-term buying opportunity.

(1) The Shanghai and Shenzhen stock markets will plunge several times every year, and each time is the best short-term buying opportunity, which has been introduced qualitatively in detail in "Judging Buying Opportunity through Tables". Here we use 10 to close at 10%- 15%, and we will encounter panic selling the next day.

(2) The index plummeted again after continuous decline, resulting in a negative deviation rate of 10%- 15% on the first day, and the decline on the second day was often at the bottom of the medium term. However, the sharp drop or plunge shortly after the head appeared at the top in the middle period led to the negative deviation rate of 10%-654338.

(3) If the market doesn't plummet or plummet, individual stocks are eager to cash out because of the huge increase, and the bookmakers make a lot of money, the stock price will continue to plummet or plummet. The negative deviation rate of 10%- 15% or even more than 20% cannot be easily bought unless the negative deviation rate on 10 is greater.

(4) The negative deviation rate of 10 is too large due to the sharp drop or plunge, and the reason for the rebound is that the short-selling power is completely released in a short time, and the space for the sharp drop is exchanged for the time for the fall. However, the average loss of investors who sold their stocks in the recent 10 trading day exceeded 10%- 15%, which was amortized. However, it will take some time for the popularity to recover, so after the plunge or plunge, it is a retaliatory rebound, and then after a certain period of time, it is a retaliatory rebound, and after a certain period of consolidation, it is an obvious increase.
