  1. The difference between the upper and lower rails of the Bollinger can be set as follows.
    The upper orbital line (UP line) = Midtore-rail line twice the standard deviation (2sd), down rail line (DOWN line) = Midtore-double-double standard deviation (2sd).
    The BOLL indicator is one of the commonly used tools in the technical analysis of the stock market. By calculating the "standard deviation" of the stock price, and then seeking the "trust interval" of the stock price. This indicator draws three lines on the graph, of which the upper and lower lines can be regarded as the pressure line and support line of the stock price, and there is a stock price average between the two lines. Set to 20. Generally speaking, the stock price will run in a channel formed by the pressure line and support line. Like MACD, RSI, KDJ and other indicators, the BOLL indicator is also the most practical technical analysis indicator of the stock market.
