    Default 破译技术指标的背离特征

    在运用技术指标时,经常会遇到期价走势与指标走势背离的现象。背离,简单地说就是走势的不一致。当背离的特征一旦出现,就是一个比较明显的采取行动的信号。

      通常指标背离有两种,一种是顶背离,另一种是底背离。顶背离通常出现在期价的高档位置。当期价的高点比前一次的高点高,而指标的高点却比指标前一次的高点低。换句话说,就适当指标处于高位,并形成一峰比一峰低的两个峰,而此时期价却对应的是一峰比一峰高,则表示该指标怀疑目前的上涨是外强中干,暗示期价很快就会反转下跌,这就是所谓的"顶背离"。是比较强烈的卖出信号。反之,底背离一般出现在期价的低档位置,当期价的低点比前一次的低点低,而指标的低点却比指标前一次的低点低,也就是说当指标认为期价不会在持续地下跌,暗示期价会反转上涨,这就是"底背离",是可以开始建仓的信号。

    能够形成明显技术指标背离特征的指标有macd,w%r,rsi,kdj等,其形态都存在与期价背离的特征。

    背离特征需要注意的问题:

    1、各种技术指标有效性并不相同。进行技术指标分析时,相对而言,用rsi与kdj的背离来研判行情的转向成功率较高。

    2、指标背离一般出现在强势中比较可靠。就是期价在高位时,通常只需出现一次背离的形态,即可确认反转形态,而期价在低位时,一般要反复出现几次背离才可确认反转形态。

    3、钝化后背离较为准确。若完全根据背离特征进行操作的话,常会带来较大的失误,这种情况特别容易出现在当期价出现暴跌或暴涨的走势时,kdj指标很可能呈高位或低位钝化后,该期价仍然出现上涨或下跌。实际上,这时候一旦出现背离特征有效性很高,特别是kdj指标结合rsi指标一起判断期价走向,kdj指标在判断顶部与底部过程中,具有较强的指向作用。

    4、注意识别假背离。通常假背离往往具有以下特征:一、某一时间周期背离,其它时间并不背离。比如,日线图背离,但周线图月线图并不背离。二、没有进入指标高位区域就出现背离。我们所说的用背离确定顶部和底部,技术指标在高于80或低于20背离,比较有效,最好是经过了一段时间的钝化。而在20-80之间往往是强市调整的特点而不是背离,后市很可能继续上涨或下跌。三、某一指标背离而其它指标并没有背离。各种技术指标在背离时候往往由于其指标设计上的不同,背离时间也不同,在背离时候kdj最为敏感,rsi次之,macd最弱。单一指标背离的指导意义不强,若各种指标都出现背离,这时期价见顶和见底的可能性较大。

    我的看法:
    其实背离在判断底顶还是很有效的
    当然背离之后还有背离
