1. MA Moving Average

MA (Moving Average) is an important reference indicator for measuring the main cost. It is used to observe the trend of price changes and test pressure and support. When used as a trend judgment, the longer the cycle, the more effective it is. On the other hand, it should be noted that when the moving average forms a long arrangement, the short-term moving average is used as the basis for holding positions.

Application rules: Ge's eight rules:

1. The moving average gradually flattens out from a downward trend. When the price breaks through the moving average from below the moving average, it is a buy signal.

2. When the price continues to rise and moves away from the moving average, and then suddenly falls but does not fall below the rising moving average, and then rises again, you can buy more.

3. Although the price temporarily falls below the moving average, the moving average is still rising and the price soon returns to above the moving average, it is still a buy signal.

4. When the price falls below the moving average and suddenly plummets continuously, and moves away from the moving average, it is very likely to rebound towards the moving average again. This is also a buying signal.

5. When the price rises rapidly and far exceeds the rising moving average, there will be a short-term decline and then tend to the moving average. This is a sell signal.

6. When the moving average trend gradually flattens and turns downward, and the price falls below the moving average from above the moving average, it should be a sell signal.

7. The price falls below the moving average and then rebounds towards the moving average, but falls back before breaking through the moving average. This is still a sell signal.

8. Although the price rises and breaks through the average line, it immediately returns to below the average line. At this time, the average line continues to fall, which is a sell signal.

2. EMA Exponential Moving Average

EMA (Exponential Moving Average) was developed to address the defect that the moving average (MA) is regarded as a lagging indicator. In order to solve the problem that once the price has deviated from the moving average and the difference has widened, the moving average fails to react immediately, EMA can reduce similar shortcomings.

Application rules: Modify the disadvantage of the moving average (MA) lagging behind the price. This indicator reacts quickly to price fluctuations and its usage is the same as that of the moving average.

1. When the short-term exponential moving average breaks through the long-term moving average from bottom to top, it is a buy signal.

2. When the short-term exponential moving average breaks through the long-term moving average from top to bottom, it is a sell signal.

3. BOLL

BOLL (Bollinger Bands) is a path-type indicator that calculates the "standard deviation" of prices and then finds the "confidence interval" of prices. This indicator draws three lines on the graph. The upper and lower lines can be regarded as the pressure line and support line of the price respectively, and the middle line is the price average line.

The price fluctuates within the range of the upper and lower limits. When the price increases or decreases, the band area will become wider, and when the price increases or decreases, the band area will become narrower. When the price exceeds the upper limit, it means overbought, and when the price exceeds the lower limit, it means oversold.

Application rules: 1. When the band of the Bollinger Bands moves horizontally, it can be regarded as being in the "normal range". At this time, when the price crosses the "upper limit" upward, it will form a short-term pullback, which is a short-term sell signal; when the price crosses the "lower limit" downward, it will form a short-term rebound, which is a short-term buy opportunity.

2. When the band moves to the upper right and lower right, it is out of the normal state. When the price continuously crosses the "upper limit", it suggests that the price will move in the upward direction; when the price continuously crosses the "lower limit", it suggests that the price will move in the downward direction.
