    Default 谈技术指标的背离

    在运用技术指标时,经常会遇到走势与指标背离的现象,背离,简单的说,就是走势不一致,当背离特征的一旦出现,就是一个比较明确的采取行动的信号,通常指标背离有两种,一是顶背离,一是底背离,顶背离通常出现在价格的高档位置,当股价的高点比前一次高,而指标的高点却比指标的前一次的高点底,也就是指标处于高位,并形成一峰比一峰低的两个峰,而此时股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,暗示股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,底背离一般出现在股价的低档位置,当股价的低点比前一次的低点低,而指标的低点却比前一次的高,也就是说当指标认为股价不会在持续下跌,暗示股价会反转上涨,这就是底背离,是可以开始买进的信号。

    能够形成明显技术指标背离特征的指标有macd,wr,rsi,kdj等,其形态都存在与股价背离的特征。

    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,就是股价在高位时,通常只需出现一次背离的形态,即可确认反转形态,而股价在低位时,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股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,该股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,特别时kdj指标结合rsi指标一起判断股价走向,kdj在判断底部与顶部过程中,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:

    某一时间周期背离,其他时间并不背离,比如日线图背离,而周线或月线图并不背离;

    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之间往往是强势调整的特点而不是背离,后市很可能继续上涨或下跌;

    某一指标背离而其他指标并没有背离,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,单一指标背离的指标意义不强,若各种指标都出现背离,这是股价见顶或见低的可能性较大。

    对技术分析已了然于心,但又绝不迷信技术分析

    背离并不实用。
