BIAS is an index to measure the degree to which stock prices deviate from the moving average. When the stock price deviates too much from the market average cost, there is a regression process, that is, the so-called "extremes meet".

1. deviation = (closing price-simple average closing price on n days)/simple average closing price on n days * 100

2. The bias indicator has three indicator lines, and the parameter of n is generally set to No.6, 12 and No.24..

65438 +0. The deviation indicator indicates the difference between the closing price and the moving average. When the positive and negative deviation of the stock price expands to a certain limit, it means that the greater the short-term profit, the higher the possibility of profit taking; When the negative deviation of stock price expands to a certain extent, short covering is more likely.

2. Deviation rate can be divided into positive deviation rate and negative deviation rate. If the stock price is greater than the average, it is a positive deviation; If the stock price is less than the average, it is a negative deviation. When the stock price is equal to the average, the deviation rate is zero. The greater the positive deviation rate, the greater the short-term overbought, and the more likely it is to peak; The greater the negative deviation rate, the greater the short-term oversold and the more likely it is to bottom out.

3. What is the percentage of buying or selling opportunities in the stock price and deviation index? Different markets, different periods, different periods and different moving average algorithms have different deviation values. In a bull market, there will be many high prices. Selling too early will miss a market, and you can sell it at the positive deviation rate of the previous high price. In the short market, it will also increase the negative deviation rate, and you can buy at the negative deviation rate point of the previous low price. 4.6 deviation > +4.5%, which is an opportunity to sell;

5. 12 bias >+6% is a selling opportunity;

6.24 deviation > +9% is a selling opportunity;

7.7 Disadvantages. Deviation indicator is that buying and selling signals are too frequent, so it should be used together with stochastic indicator (KDJ) and bollinger Band indicator (boll).

1. Due to the different characteristics of individual stocks, investors need to calculate the best limit trading value suitable for the individual stock market.

2. The stock price suddenly rises and falls due to the influence of major emergencies, and the deviation index will be surprisingly high or low. However, the probability of occurrence is extremely small, which can only be regarded as a special case and cannot be used as a daily judgment standard.

ASI- Cumulative Shock Index shows that ASI Cumulative Shock Index tries to design a perception line by adjusting the myth about the opening and closing of the index, thus representing the real market, and providing a quite incisive explanation for the breakthrough of pressure line and support line, the confirmation and deviation of new highs and new lows. Theoretically, ASI quantifies the high point of shock, and indeed defines the short-term shock point, on the other hand, it also shows the connotation of the market truly and powerfully. We should use 1. The stock price and ASI index rose simultaneously. When ASI leads the stock price to break through the previous high point, it is a buy signal. 2. The stock price and ASI index fell simultaneously. When ASI's leading share price falls below the previous low, it is a selling signal. Use skills 1. The stock price is high and low, but ASI is not high and low, indicating that this high and low point has not been confirmed. 2. The stock price breaks through the pressure line or support line, but ASI is not accompanied, which is a false breakthrough. 3. The significant high and low points formed before ASI are regarded as ASI stop loss points; When the bulls were long, ASI fell below the previous low and stopped selling; When shorting, ASI broke through the previous high stop loss. 4. When the stock price is low and the ASI index is not low, it is the bottom deviation; When the stock price hits a new high, but the ASI index is different from the new high, it is a top deviation. I'm sorry, because studying and engaging in the financial industry abroad, I personally think that the bias value is not the most important. What is important is the process of regression analysis and the overall evaluation of all coefficient indexes including regression value, deviation and * * * deviation.
