    Default 什么是双顶及运用

    双顶通常被称为"m顶",双底被称为"w底"都是最常见的反转形态,出现很频繁。理想的双重顶具有两个显著的峰,其价格水平大致相同,在第一个峰时交易量上升,在第二个峰时交易量下跌,价格无力冲破上次高点,当价格决定性的收于谷底之下,双顶形态完成,标志着趋势向下方的反转。从市场心理而言,当市场要回头时,往往心有不甘,会尝试回到原来的趋势,在 彻底失败后,才会心甘情愿的掉头而走。一般,双峰之间持续的时间越长,形态的高度越大,即将来临的反转潜力就越大。从技术图表来看,一个升浪,由a点出发,涨至b点为顶峰,回头跌至c点,卷土重来又上至b点差不多的价位d点,形成另一个顶峰。跟着就摔下来,跌破颈线,成为一个跌势的序幕。这种走势形态,因为有两个价位相近的顶,所以一般称之为双顶。 又因其图形与英文字母m相似,故又叫m顶。相反,在下跌势的末期出现双底的,就叫w底。m顶是强烈的下跌信号,w底是可靠的上升征兆。(参看什么是双底及运用以便对比)

    双顶形态形成时,许多常用的技术指标,如kdj、rsi、macd等会同时出现顶背驰信号,这些指标可以帮助投资者确认底部的形成。
    双底形态由于价格经历了两次探顶,建议投资者买入点选在突破颈线后回抽确认时卖出。多数双顶形态形成后,都有一个ef回抽机会。

    双顶的最低量度跌幅之计算方法有两个:
    第一,依照附图的量度方法,以双顶形态的高度由b点开始计算;
    第二,出现参差顶时候,则以a点与b点的垂直距离作为预测跌幅的量度基础。间中会出现第二个顶较第一个顶更高的情形。在这情况下,判断是否仍然可能形成双顶形态,可根据下列两点加以分析:

    (一)、突破价位是否足够百分之三;

    (二)、收市价是否连续两日均高於第一个顶。

    上述辨别方式并非不会出错,但最低限度可减少发出假讯号的机会。另外值得一提的,尚下列两点:

    (一)、两个顶相距离时间愈长,下跌幅度愈大;

    (二)、双顶高度与下跌幅度成正比

    双顶如果没破,做空单好些
