1, moving average (MA)

Moving average, referred to as m a and MA, is a technical index that averages the securities prices (indexes) in a certain period through statistical analysis, and connects the averages at different times to form a MA to observe the changing trend of securities prices. Moving averages can be divided into short-term moving averages, medium-term moving averages and long-term moving averages according to the length of time.

2. Exponential moving average

EMA (exponential moving average) is an exponential moving average, also called EXPMA indicator. It is also a trend indicator, and the exponential moving average is a weighted exponential decreasing moving average. Its construction principle is: use the weighted arithmetic average of closing price to judge the changing trend of future price trend.

Compared with MACD indicator and DMA indicator, EMA indicator is a trend analysis indicator, because its calculation formula focuses on the weight of current price (current market), which overcomes the lag defect of MACD indicator in the use of price trend and eliminates the signal lead of DMA indicator in a certain moment, so it is a very effective analysis indicator.

3. Bollinger Band

Boll index is one of the commonly used tools for technical analysis of stock market. By calculating the "standard deviation" of stock price, we can find the "trust interval" of stock price. The indicator has drawn three lines on the map, in which the upper and lower lines can be regarded as the pressure line and the support line of the stock price respectively, and there is an average line of the stock price between the two lines, and the parameter of the Bollinger Band indicator is preferably set to 20. Generally speaking, the stock price will run in the channel formed by the pressure line and the support line.
