Time-sharing chart, also called real-time chart, is a technical graph that displays the trading information of stock market in real time on a coordinate chart with curves. The horizontal axis of the coordinates is the opening time, the upper part of the vertical axis is the stock price or index, and the lower part shows the trading volume. Time-sharing charts are divided into exponential time-sharing charts and individual stock time-sharing charts.
(1) exponential time-sharing graph. The white curve represents the total market index published by the Shanghai Stock Exchange, that is, the weighted number. The yellow curve is a large-scale index without weight. No matter how many listed stocks are issued, the influence of all stocks on the Shanghai Composite Index is treated equally.
Referring to the relative position relationship between the white curve and the yellow curve, the following information can be obtained:
When the index rises and the yellow curve is above the white curve, it shows that the stocks with a small number of issues (small stocks) have a large increase; When the yellow curve is below the trend of the white curve, it shows that the stocks with a large number of issues (large market) have a large increase.
When the index falls, if the yellow curve is still above the white curve, it means that the decline of small-cap stocks is less than that of large-cap stocks; If the white curve is above the yellow curve, it means that the decline of small-cap stocks is greater than that of large-cap stocks.
The red and green bars reflect the comparison of the number of transactions of all stocks in the current market. The growth of red column means that buying is greater than selling, and the index will gradually rise; Shortening the red column means selling more than buying, and the index will gradually fall. Green column growth, index decline increased; The green column is shortened and the index decline is reduced.
The yellow bar indicates the turnover per minute, and the unit is hand (100 shares/hand).
(2) Time-sharing chart of individual stocks. The white curve represents the time-sharing transaction price of this stock. The yellow curve represents the average price of this stock. The yellow bar indicates the turnover per minute, and the unit is hand (100 shares/hand).
Time-sharing chart is the real-time data of on-site trading in the stock market, and it is also an important basis for judging the stock market.
What is RSI analysis?
RSI is the abbreviation of "RelativeStrengthIndex", that is, relative strength index. Simply put, it is to infer the direction of future price changes from the relationship between stock price changes in a certain period of time. In foreign countries, RSI has long been used by futures market investors to speculate on commodities; Later, stock technical analysts found it suitable for the stock market, so they introduced it for promotion. The accuracy and credibility of RSI are very good. If it is combined with other technical analysis methods such as moving average, it can improve the accuracy of judging the general trend of stock market and the changing direction of individual stock prices, and become a familiar analysis method for many short-term investors.
To calculate RSI, we must first master the following two formulas:
Strength index (RSI) =100-[100/(1+RS)]
Relative strength (RS) =/kloc-the average of the sum of closing gains on the 4th//kloc-the average of the sum of closing losses on the 4th.
Step 1: You need to collect the closing price or index before 14. As for the closing days as a sample, stock market standards vary from country to country. The sampling scale should not be too small, otherwise the calculated RSI is too sensitive and reduces the reference value. At present, there are three popular sampling modes: 6 days, 9 days and 14 days. At present, Shenzhen Stock Exchange and Shanghai Stock Exchange publish the RSI calculated by these three models every day, which are represented by RSI(6), RSI(9) and RSI( 14) respectively.
Step 2: Calculate the ratio of the average value of the sum of rising numbers to the average value of the sum of falling numbers on 14.
Step 3: Calculate the strength index RSI.
To calculate a new day's strength index, just multiply the average closing price increase (decrease) of the previous day by 13, add today's closing price increase (decrease), and then divide it by 14, and it can be calculated according to the formula of [100/( 1+RS)].
For example, the recent 14-day stock price index rose by 4 points on the first day, fell by 3 points on the second day, rose by 3 points on the third and fourth days, fell by 2 points on the fifth and sixth days, rose by 4 points on the seventh day, fell by 4 points on the eighth day, fell by 6 points on the ninth day, rose by 2 points on the tenth to twelfth day, and fell by 4 points on the thirteenth and fourteenth days.
"14 average of the sum of closing price increases" = (4+3+3+4+2)/14 = 20/14 =1.429.
"14-day closing decline sum average" = (3+2+2+4+6+4+4)/14 = 25/14 =1.786.
Relative strength (RS) =1.429/1.786 = 0.80.
So RSI =100-[100/(1+0.80)] =100-55.556 = 44.444. This is the strength index (RSI) of the above 14 day.
How to use RSI to analyze the stock price trend?
By analyzing the strength indicators, we can judge the trend of the stock price. RSI is limited between 0 and 100, that is, 0.
For example, a stock continues to rise, the stock price rises from 30 yuan to 40 yuan, and the strong index reaches 85, indicating that the stock has been overbought; If the share price rises again, it will soon fall back, because the buyer's motivation is weakened. On the other hand, if a stock continues to fall, the stock price falls from 20 yuan to 10 yuan, and the strong index falls to 15, indicating that it has oversold; If the stock price falls again, it may rise again because the seller becomes weaker and the buyer becomes stronger.
As an investor, we should analyze the stock price trend through the relative strength index as soon as possible, seize the opportunity and buy or sell in time.
