1. Deviation rate is a technical index derived from the principle of moving average. Its function is to measure the deviation of the stock price from the moving average in the process of fluctuation, so as to get the retracement and rebound that may be caused by the deviation of the stock price from the moving average when the stock price fluctuates violently. Deviation rate is divided into positive and negative values, and when the stock price is above the moving average, it is positive; When the stock price is lower than the moving average, it is negative; When the stock price is consistent with the moving average, it is zero.

2. The basic principle of deviation rate is that if the stock price is too far away from the moving average, it won't last long, but it will approach the moving average again soon:

(1) Generally speaking, in a weak market, the 5-day deviation rate > 6 is an overbought phenomenon and an opportunity to sell. When it reaches below -6, it is oversold and a buying opportunity.

(2) In a strong market, it is a buying opportunity to overbought when the 5-day deviation rate is greater than 8 and oversold when it reaches -3.

(3) When the general trend rises, there will be many high prices, which can be thrown at the right or wrong point of the previous high price. When the general trend falls, there will also be many low prices, which can be bought at the negative deviation point of the previous low price.

(4) It is not easy to judge the positive and negative deviation in the board, and it should be comprehensively analyzed and judged in combination with other technical indicators.

(5) If there is a negative deviation rate when the general trend rises, you can buy it when it falls.

(6) If there is a positive deviation rate when the general trend falls, it can be thrown at a high price when it picks up.

CCI index, also known as homeopathic index, is called "commodity channel index" in English. It was founded by Donald Lambert, an American stock market analyst, and it is a stock market analysis tool focusing on judging stock price deviation.

Principle and calculation method of CCI index

First, the principle of CCI index

CCI index was put forward by Donald Lambert in 1980s, which is a relatively novel technical index. It was first used to judge the futures market, and later used to judge the stock market, and was widely used. Different from most technical analysis indexes invented only by using the closing price, opening price, highest price or lowest price of a stock, CCI index is a unique technical analysis index, which introduces the concept of the average interval deviation between the price and the stock price in a fixed period according to the statistical principle, and emphasizes the importance of the average absolute deviation of the stock price in the technical analysis of the stock market.

CCI index is a kind of overbought and oversold index, which is specially used to measure whether the stock price is beyond the normal distribution range, but it has its own uniqueness compared with other overbought and oversold indexes. Most overbought and oversold indicators, such as KDJ, WR%, CCI, etc. There is an upper and lower bound of "0- 100", so it is more suitable for judging the general normal market, and when the price trend of those stocks rises and falls in a short time, the index may be passivated. However, CCI index fluctuates between positive infinity and negative infinity, so there will be no passivation of the index, which will help investors to better judge the market, especially those abnormal markets with short-term ups and downs.

KDJ, right

The Chinese name of KDJ indicator is stochastics, which originated from the futures market.

The application law of KDJ index KDJ index is three curves, which are mainly considered from five aspects in application: the absolute number of KD value; The form of KD curve; KD index crossing; Deviation of KD index; The value of the j index.

First consider the value of KD. The range of KD is 0 ~ 100, which is divided into several areas: over 80 is overbought area, below 20 is overbought area, and the rest is wandering area.

According to this classification, if KD exceeds 80, we should consider selling, and if KD is below 20, we should consider buying. It should be noted that the above division is only a preliminary process of applying KD index, and it is just a signal. If you operate completely in this way, it is easy to lose money.

Second, consider from the shape of KD index curve. When the KD index forms a head-shoulder top shape and multiple tops (bottoms) at a higher or lower position, it is a signal to take action. Please note that these forms must appear in a higher or lower position. The higher or lower the position, the more reliable the conclusion.

Third, consider from the intersection of KD indicators. The relationship between K and D, like the relationship between stock price and MA, also has the problems of death crossover and gold crossover, but the application of crossover here is very complicated, and many other conditions are attached.

Take the bottom-up intersection of K and D as an example: K intersection D is a golden intersection and a buying signal. However, whether you should buy a gold fork depends on other conditions. The first condition is that the position of the golden fork should be relatively low, especially in the oversold area. The lower the better.

The second condition is the number of times to intersect with d, sometimes in the low position, k and d have to intersect back and forth several times. The minimum crossing times is 2, and the more the better.

The third condition is the position of the intersection point relative to the low point of KD line, which is often referred to as the "right intersection point" principle. K only intersects D when D looks up, which is much more reliable than when D is still falling.

Fourth, consider from the deviation of KD index. If KD is high or low, if it deviates from the trend of stock price, it is a signal to take action.

Fifthly, if the value of J index exceeds 100 and is lower than 0, it belongs to the abnormal price area. More than 100 is overbought, less than 0 is oversold.
