5-day moving average (attack line): the stock price rises and breaks through the attack line, showing an upward trend and short-term bullish. Similarly, if the stock price falls below the 5-day moving average, it will be short-term bearish.

The moving average is an important technical index that investors often use. It is an average line obtained by dividing the sum of closing prices in a certain period by the period. If there are five trading days in a week, that is, the closing prices of five days are added up and divided by five, the average closing prices of these days can be obtained. Of course,10,20 and so on are also calculated in this way.

The parameters referenced by the moving average are different, and their functions and responses are also different. Commonly used parameters are No.5, 10, No.20, No.30, No.60,120,250. Common colors are white (line 5), yellow (10), purple (line 20), green (line 30), gray (line 60), blue (120) and orange (line 20), but there is no uniform regulation on colors, so investors can.
