    Default 对称三角形

    对称三角形(Symmetrical Triangle)又称为等边三角形,一般情形之下,对称三角形是属于整理形态,即价格会继续原来的趋势移动。它是由一系列的价格变动所组成,其变动幅度逐渐缩小,亦即每次变动的最高价,低于前次的水准,而最低价比前次最低价水准高,呈一压缩图形。如从横的方向看价格变动领域,其上限为向下斜线,下限为向上倾线,把短期高点和低点,分别以直线连接起来,就可以形成一对称的三角形。

    对称三角形成交量,因愈来愈小幅度的价格变动而递减,正反映出多空力量对后市犹疑不决的观望态度,然后当价格突然跳出三角形时,成交量随之而变大。

    若价格往上冲破阻力线(必须得到大成交量的配合),便是一个短期买入讯号;反之,若价格往下跌破(在低成交量之下跌破),便是一个短期沽出讯号。

    上图为例,下降趋势出现当价格从A点流入对称三角形及交易徘徊在这个区域。趋势线亦在随后两个月出现(A点至C点和B点至D点)。在E点,价位开始穿破阻力线,尝试转势,但不成功,却成为一个假突破。这是一个很好的例子,可提醒投资者必须等待收市后的讯号,及并留意破位是否准确或是否一个好的入市位。在E 点,价格在趋势线下开市,确认先前的讯号是假的。随后,价格穿破三角形的下点及大量沽盘,这确认了对称三角形的下跌趋势持续。
