    Post 双底形态的演变与操作

    一、双底形态的构成

    图形所示的为一个典型的双底反转形态,从这个形态中我们可以看出双底在构成前后有4个显着的要素,作为我们判定某阶段走势是否为双底的依据:

      原有趋势为下跌趋势

      具备两个显着的低点,且价位基本接近,有跨度(即两个点要相互呼应)

      第二次探底的节奏和力度要有放缓迹象

      有效向上突破颈线确认

    在实际判断中,很多投资者最容易遗漏的是第一点,其实也是最关键的一个点:原来为下跌趋势。我们从下一部分的内容更清晰地去理解

    二、双底形态的位置判断

    这幅图的左右两个部分分别为两段不同的走势,其中左边部分相信很多投资者更为熟悉,这是欧元/美元在2004年一季度前后的走势。

      左边:当时的汇价显然运行在一段涨势之中,此后的回调过程形成了w形的调整,但这并不是双底,此后的走势也证明了汇价向上突破并未达到双底形态的最小理论幅度。

      再次提醒:双底形态是底部反转形态,理所当然地需要出现在下跌趋势后才有依据,此处实际是构筑了一个双顶形态。

      右边:右边图形的蓝色部分同样是一个假双底,显然仍出现在一段涨势之后;而红色部分则出现在一轮下跌走势中,以二次探底后的向上突破确认了双底形态的成立。

    对于炒短线的投资者,分时图上也有双底和双顶,利用好同样有效
