20200925: k-line

1. Understand the previous quantization factors f1~f5 from the k-line perspective.

Among them, close, open, high, and low respectively represent the closing price, opening price, highest price and lowest price of the daily stock; turnover represents the daily turnover rate; returnPast1d represents the increase or decrease of the daily closing price relative to the previous day's closing price ; Cap represents the circulating market value at the close of each day. These 7 factors are called original stock factors, and each component of the observation vector is called a feature.

From the perspective of k-line analysis, look at these 5 factors: f1 is the percentage of the entity size relative to the opening price, that is, the entity size excludes the influence of the base; f2 and f3 are the percentages of the upper and lower shadow lines relative to the opening price, respectively , That is, the length of the shadow excludes the influence of the base.

2. Three elements of k-line

• Yin and Yang combing represents the overall trend: the number of Yin and Yang k-lines shows an overall upward or downward trend. Yangxian is mostly in an upward trend, and Yinxian is mostly in a downward trend.
• The size of the entity indicates the strength of the internal power and trend: the size of the entity of the k-line is the external performance of the size of the internal power. In layman's terms, the greater the mass and the faster the object, the greater the inertial impact force, and the length of the entity indicates the increase. Or the strength of the downtrend, the larger the Yangxian entity indicates the more sufficient internal upward momentum, and its upward momentum is greater than the small Yangxian entity. Similarly, the larger the Yinxian entity, the greater the downward momentum.
• The length of the shadow line reflects the willingness to turn: when the entity of the bar does not change much, the upper shadow line and the lower shadow line are getting longer and longer, indicating that the market volatility is increasing and the long-short game is becoming more and more intense.

K-line technical analysis is the basic technology in investment, and it is also the core technology. The reason why it is a basic technology is that most of the technical indicators in technical analysis are derived from the k-line, and they are designed on the basis of the k-line; the reason why the k-line technical analysis is the core technology is because of the composition of most graphics They are all derived from the k-line, so the key to investors' operation is to eliminate noise and find the core k-line in the process of capital attitude transformation and strong and weak brewing.

3. How to judge the pressure line (resistance line) and support line through the k-line?

Method 1: Through the golden section method.

• In the rising market, we are concerned about where the rise will be under pressure. The position provided by the golden section line is the base point price multiplied by a special number.
  • Assuming that the base price is 10 yuan, then 10.00 = 10*1.000 13.82=10*1.382 15=10*1.500 16.18=10*1.618 20.00=10*2.000 26.18=10*2.618 
  • These price levels may become pressure levels in the future, of which 16.18 and 26.18 are the most likely to become pressure lines. Those over 20 are rarely used. If you are in a highly active market with sharp fluctuations in stock prices, this method is prone to errors.
• In the same way, when the market is falling, we care about where the falling will be supported. The golden section provides the following price levels, they are 8.09=10*0.809 6.18=10*0.618 5=10*5 3.82=10*0.382 1.91=10*0.191, these price levels are very likely to become support, of which 6.18 Yuan and 3.82 Yuan are the most likely.
• The golden section line is to use the principle of the golden section ratio to analyze the market and give the corresponding tangent position in turn. The principle of the golden section is derived from the Vobona odd series. The well-known golden ratio of 0.618 is the ratio of two adjacent numbers in the Vobona odd series. At the same time, more important ratios such as 0.191, 0.382, 0.809 are calculated based on this. . Among them, the most commonly used ratios in the golden section are 0.382 and 0.618. Applying this to the analysis of the currency market, it can be understood that the positions corresponding to the above ratios are generally prone to strong support and pressure. After the end of a round of intermediate market, the trend of the foreign exchange market or exchange rate will move in the opposite direction. At this time, whether it is from a downward trend to an upward trend or from an upward trend to a downward trend, the important high in the secondary trend market The rise and fall between the point and the low point is used as the range of the analysis. The original rise and fall are divided into 5 golden points according to 0.191, 0.382, 0.50, 0.618, and 0.809. The exchange rate will likely be in these gold points after the market reverses. Temporary resistance or support is encountered at the split point.
• It should be noted when applying the golden section line and the percentage line: For the golden section line, the two most important lines are 0.382 and 0.618. In the rebound market, the 0.382 position is the weak rebound target position, and the 0.618 position is the strong rebound target position. In the callback process, if it is a strong callback, there should be strong support at the 0.382 line. If it is a weak callback, the 0.618 line is the strong support level.
• For example, the support level of a certain market retracement can be calculated by the following formula:
• 　　The support level of a certain market retracement = a certain market high-(a certain market high-a certain market lowest) * 0.382 (or 0.618).
