波林格区间的中文解释

技术分析的一种方法。在收盘价的移动平均线上下一个标准差处各画一条线，便形成波林格区间。标准差量度价格的波动性，因此，这些区间随波动性的变化或缩窄或扩大，即市场平静时，区间缩小，市场波动时，区间扩大。区间缩窄意味着新趋势的开始，这可从价格出现突破并收于区间之外得以证实。波林格区间可用于任何价格走势图，但最常见的是与柱状图一起使用（见图3）。

Bollinger Bands的英文解释

Used in technical analysis. Bollinger bands are lines plotted one standard deviation above and below the moving average of the closing prices. A standard deviation measures price volatility so these bands narrow and widen in line with volatility - narrow in calm markets and wide in volatile markets. The narrowing of the bands often indicates the start of a new trend, which is confirmed when prices break and close out of the band. Bollinger bands may be used with any price chart but are most commonly used with bar charts.
