First, we need to collect relevant data, including weekly opening price, highest price, lowest price and closing price. Then, we can get the weekly price change by calculating the difference between each price and the previous week's price. These price changes can be regarded as a force of the market, which can help us to judge the market trend.
Next, we need to integrate these price changes. The purpose of integration is to eliminate the random fluctuation of data and let us see the real trend of the market more clearly. We can add up these price changes and get a total price change. This total price change is the weekly integral.
Some useful information can be obtained by observing the weekly integral. If the weekly integral is positive, it means that the market is rising; If the weekly integral is negative, it means that the market is falling. In addition, you can also judge the strength of the market by comparing the weekly integrals in different time periods. For example, if the latest weekly score is greater than the previous weekly score, it means that the market is stronger now than before.
Generally speaking, through weekly integration, we can better understand the long-term trend of the market and make more accurate investment decisions. However, we also need to note that no technical analysis tool can guarantee the accuracy of 100%, so we need to combine other analysis methods, as well as our own experience and judgment in using weekly integral.
