看涨碰头线

该形态通常在价格向下走低的趋势中形成。该形态第一天是一根长阴烛。第二天开盘价格迅速下跌,对空头十分有利。看涨碰头线形态与看涨刺透线形成的过程类似,唯一的不同是价格在第二日反弹的水平。

碰头线只有在高于第一日收盘价时形成,而刺透线第二日穿过第一日蜡烛烛体的中点。但是刺透线要比看涨碰头线的信号更强。该形态应该与上颈线(On Neck Line)区分开来。

看跌碰头线

碰头线形态也和乌云盖顶形态类似。看跌碰头线开盘创新高,并在前一日的收盘价收盘,而乌云盖顶跌至中点以下。

如何辨识这一形态?

1. 两线的烛体都在当前趋势的方向上。
2. 第一日烛体的颜色总是反应趋势:阴烛代表下跌而阳烛代表上涨。
3. 第二日蜡烛颜色相反。
4. 两日收盘价相同。
5. 两日烛体都较长。

碰头线的可能情形和形态心理

下降趋势中形成一根长阴烛,加强了当日的看空气氛。第二日价格向下跳空开盘。在一整天当中价格爬升,最后收于前一日的同一水平。此时趋势反转的可能性非常高。如果第三日开盘更高,即为确认信号。

形态变化

该形态由两根长烛组成。但是大多数情况下第二日蜡烛短于第一日。这并不影响形态的可靠性,但确认信号依然需要。最理想的情况是每天都是光头烛收盘。

形态失效

碰头线形成单根蜡烛时无法提供确认信号。单根蜡烛看起来像是形态的第一烛,但其影线和第二天同方向。此时既不能确认形态,也不代表信号不强。

相关形态

与碰头线相对的是代表持续形态的分手线。此外,如果第二日的蜡烛烛体超过了第一日的,形态可能发展为乌云盖顶或刺透线形态。
