Bollinger bands（布林带（Bollinger bands））¶
A Bollinger band plot is a type of technical analysis tool used by traders and investors to analyze and identify potential trends, price volatility, and market sentiment in financial markets. The plot consists of two bands plotted around a simple moving average (SMA) on a configurable rolling time window. These bands are:
- Upper Bollinger band: This band is plotted at a multiple of standard deviations (typically 2) above the moving average.
- Lower Bollinger band: This band is plotted at a multiple of standard deviations (typically 2) below the moving average.
As shown in the example below, these bands are usually plotted together with the moving average itself and they can be added separately using the rolling aggregate plot.
Bollinger bands are also called Statistical Process Control (SPC) or Statistical Quality Control (SQC) charts.

布林带（Bollinger bands）¶
布林带图是一种技术分析工具，交易者和投资者常用它来分析和识别金融市场中的潜在趋势、价格波动性以及市场情绪。该图表由两条围绕简单移动平均线（SMA）绘制的带状线组成，基于可配置的滚动时间窗口。这两条带状线分别是：
- 上布林带（Upper Bollinger band）： 该带状线绘制在移动平均线上方，距离为若干个标准差（通常为2倍）。
- 下布林带（Lower Bollinger band）： 该带状线绘制在移动平均线下方，距离为若干个标准差（通常为2倍）。
如下例所示，这些带状线通常与移动平均线本身一起绘制，也可以使用滚动聚合图单独添加。
布林带也被称为统计过程控制（Statistical Process Control, SPC）图或统计质量控制（Statistical Quality Control, SQC）图。
