Bollinger bands 布林線指數定義

布林線指數是一種常用的價格技術指標形式。該指標由技術交易領軍人物約翰.布林于20世紀80年代開發使用。

布林線指數包含了市場的移動平均值,以及價格通道的上線和下線每個價格通道(或稱“帶”)代表了標準差與市場移動平均值的偏差程度。

如果市場趨向震蕩,則布林帶將擴大(稱為“擴張”),而市場趨向平穩時,布林帶趨向收縮(“緊縮”)。因此,交易者可以根據布林帶判斷短期波動程度,並且窺視長期價格波動情況。

布林線指數的使用也可以指出是否市場正進入超買或超售的情況。當市場價格持續向上突破布林帶參數範圍,則應視為超買;而當期向下跌穿布林帶時,則應視為超賣。

儘管對大多數交易者而言,布林帶判斷非常有用。但是該指標也並非萬無一失,並且只有結合充分了解市場的基本面和技術面分析,方可見效。如需了解更多, 敬請閱讀我們的技術面分析指南
