1. If 6th is taken as the parameter of short-term William indicator, when the value of William indicator is less than 15, it can be classified as short-term overbought of William indicator, which is a short-term selling signal.

2. If the 6th day is taken as the parameter of short-term William indicator, when the value of William indicator is greater than 85, it can be classified as short-term oversold of William indicator, which is a short-term buying signal.

3. If 20 is taken as the parameter of the medium-term William indicator, when the value of the William indicator is less than 20, it can be classified as the medium-term overbought of the William indicator, which is the mid-line selling signal.

4. If the 20th is taken as the parameter of the mid-term William indicator, when the value of the William indicator is greater than 80, it can be classified as the mid-term oversold of the William indicator, which is a mid-line buying signal.

5. If 70 days is taken as the parameter of long-term William indicator, when the value of William indicator is less than 10, it can be classified as long-term overbought of William indicator, which is a long-term selling signal.

6. If 70 days is taken as the parameter of long-term William indicator, when the value of William indicator is greater than 90, it can be classified as long-term oversold of William indicator, which is a long-term buying signal.

Speaking of William index, we all know that it is an index to study the short-term changes of stocks. It judges the phenomenon of overbought and oversold by analyzing the relationship between the highest price, the lowest price and the closing price of a stock in a period of time.

It is understood that the WR Williams Index was put forward by Larry Williams in 1973. WR is an index to measure market volatility, which refers to the principle of buying when it is strong and selling when it is weak. It is a technical index to analyze the short-term trading trend of the market and provide trading reference for investors. William index is a technical index to analyze the short-term trading trend of the market. It judges the overbought and oversold phenomenon of the market by analyzing the relationship between the high, low and closing price in a period of time, predicts the short-term and medium-term trend of the price, reflects the overbought and oversold behavior of the market by using the shock point, and analyzes the comparison between the long and short sides, thus putting forward an effective signal to judge the short-term behavior trend of the market. Its significance is to show the relative position of the closing price of a certain day in all price ranges of the past few days. It was used in the futures market in the early days, and then widely used in the stock market. Here we will talk about the application of William indicator in the futures market. I hope the summary here is helpful to everyone.

The use of William indicator is mainly considered from two aspects:

One is the absolute value of William index,

The second is the shape of William exponential curve. The calculation formula of William index shows that the value of William index is between 0- 100, and it is divided into upper and lower regions with 50 as the central axis. In the first half, the William index is less than 50, indicating that the market is in a strong position, and 0-20 is an overbought area. In the second half, the William index is greater than 50, indicating that the market is in a weak position, and 80- 100 is an oversold area.

First, considering the absolute value of WMS, when WMS is higher than 80, it is oversold and the market is about to bottom out. Generally, line 80 will become a buying line, so we should consider buying. When WMS is below 20, it is overbought and the market is about to peak. Generally, line 20 will become a selling line and should be considered for selling.

Second, considering the curve shape of WMS, WMS will generally turn back after entering a high position. If the price continues to rise, it will deviate, which is a selling signal. After WMS enters the low position, it will generally rebound. If the price continues to fall, it will deviate and be a buying signal. WMS touches * (bottom) several times in a row, and some of them form double or multiple * (bottom), which is a signal to sell (buy). William indicator is a short-term trend indicator. In actual futures trading, when the William indicator starts to overbought and oversold, the price will start to rise or unilaterally fall, which needs special attention.
