Psychological line PSY index is a reference technical index based on the study of investors' psychological tendency, analyzing the psychology and facts that investors tend to buyers and sellers in a certain period of time, and conducting stock trading.
Second, the calculation of PSY index
Psychological line PSY index mainly explores the strength comparison between long and short sides from the psychological aspect of stock investors' trading tendency. It is calculated according to the number of days that the closing price rises or falls in a period of time, and its calculation method is very simple. The calculation formula is as follows:
PSY (North) =AN 100
Where n is the parameter of period and PSY, which can be day, week, month and minute.
A is the number of cycles in which the stock price rises.
For example, when n = 20 days, if 12 days rises and 8 days falls, then PSY(20 days) =60.
The rise and fall are judged according to the closing price here. If the closing price of a daily cycle is higher than that of the previous cycle, it is considered as an increase; If it is lower than the closing price of the previous cycle, it is determined to be a decline.
The parameter selection of psychological line PSY is artificial and can be determined according to investors' preferences and market changes. Parameter selection is an important means for PSY indicators to judge the market. The larger the parameter selection, the more concentrated and stable the range of PSY, but it has the disadvantage of lag; The parameter selection is small, and the value range of PSY fluctuates greatly and is sensitive.
On most stock market analysis software, the periodic range of PSY index is 0- 100. Generally speaking, the base date of the daily line is 3 days, and the range of values is 3 days to 90 days; The reference week of the weekly line is 3 weeks, and the range of values is 3 weeks to 50 weeks; The base month of the monthly line is March, and the range of values is March-May.
Like the calculation of other indicators, PSY indicators include daily PSY indicators, weekly PSY indicators, monthly PSY indicators, annual PSY indicators and minute PSY indicators. Daily PSY index and weekly PSY index are often used in stock market research. Although their calculated values are different, the basic calculation method is the same.
General criteria for judging PSY index
Psychological line PSY index is a short-term index in stock market technology, which mainly reflects the psychological overbought or oversold of investors in the market. It is suitable for judging the general trend and can also be used to judge the stock market. It plays an important role in measuring the psychological endurance of investors and the rise and fall of market popularity, and is an auxiliary index reflecting market energy in technical analysis of stock market.
In the technical analysis software of stock market, the general criteria for judging PSY index mainly focus on the value of PSY index, the overbought and oversold of PSY value, the trend of PSY curve and the shape of PSY curve. Taking the daily cycle standard as an example, the specific conclusions are as follows:
First, the value of PSY index.
The values of 1 and PSY are always between 0 and 100, where 0 is the lower limit extreme value of PSY and 100 is the upper limit extreme value of PSY. The value 50 is the dividing line between the long side and the short side.
2. The PSY value greater than 50 is a multi-party area of the PSY indicator, indicating that the number of days of rising in N days is greater than the number of days of falling, and many parties are dominant, and investors can hold shares to be increased.
3. The PSY value less than 50 is the empty area of the PSY indicator, indicating that the number of days rising in N days is less than the number of days falling, and the empty side is dominant, so investors should wait and see with money.
4.PSY hovers around 50, reflecting that the number of days that the stock index or stock price rises in recent days is basically equal to the number of days that it falls, and the long and short forces remain balanced, and investors mainly wait and see.
Second, the overbought and oversold situation of PSY value
1. Under normal circumstances, the change of PSY value is between 25 and 75, reflecting that the stock price is in a normal fluctuation state, and investors can buy and sell stocks according to the original ideas.
2. In the case of consolidation, the value of PSY index should be around 50, and the upper and lower limits are generally set at 25 and 75 (some are set at 30 and 70), indicating that the long and short sides are basically balanced. If PSY is out of this equilibrium, then it is overbought and oversold.
3. When PSY reaches or exceeds 75. It shows that in N days, the number of rising days is much greater than the number of falling days, and the power of many parties is very strong and lasting. On the other hand, there are signs of overbought in the market, especially in the case of a large increase, the pressure of stock price rise will be great, and the stock price may fall back and adjust soon, so investors should pay more attention.
4. When PSY reaches or falls below 25, it means that in N days, the number of days of decline is far greater than the number of days of rise, the empty force ratio is strong, the market pessimism is strong, and the stock price has been falling all the way. However, on the other hand, due to more days of decline, the market shows signs of oversold, especially in the case of a large decline, the market selling is rare and the selling pressure is light, and the stock price may rebound upwards.
5. If the PSY value is greater than 90 or less than 10, investors should pay more attention.
6. In the early stage of bull market and short market, the overbought line and oversold line can be adjusted to 85 and 15, and then adjusted back to 75 and 25 in the middle and late stage of market development, which is more conducive to the judgment of PSY index.

I hardly look at this indicator! I don't think I've heard of it
Of course, that sentence suits you best!
I just pulled up the bottom picture of the PSY line indicator!
I saw some tickets! Maybe I am not familiar with it! Personal feelings often do not fully reflect the rise and fall of stock prices! !
It may be my first contact! ! )
