外汇中的布林线指标

布林线指标得名于现在著名的市场技术员约翰·布林,它是一项趋势指标。这意味着可以将其应用于图表,交易者利用它来掌控趋势和找出反转形态。事实上,该指标由类似一个通道的三条线组成,分别称之为布林带上轨 (UBB)、中轨 (MBB) 和下轨 (LBB)。根据该指标做交易决策时,所有线条同等重要,而 MBB 又具有特殊意义。视乎交易者使用的经纪商和交易平台不同,MBB 分为简单移动平均线 (SMA) 和指数移动平均线 (EMA) 两种。阅读外汇交易学院的移动平均线主题文章就会发现,在移动平均线策略中,建议采用简单移动平均线来找出支持位和阻力位。但在使用布林线指标时,建议使用 MBB 指数移动平均线。这是因为 EMA 及时适应新价格点位,使 MBB 成为一条主动线,而非被动线。下图展示了如何在 MetaTrader 4 交易平台图表上绘制布林线指标。和所有其他趋势指标一样,点击“插入/指标/趋势”,选中“布林线指标”,屏幕将显示一个弹出窗口。

交易者可以在弹出窗口(见下方)中编辑指标,为 MBB 选择变量、颜色和待绘制的三条线粗细。建议为 MBB 选择 20 个周期,平均应用于每根蜡烛线的收盘价上。

如何利用布林线指标进行交易

与外汇交易学院之前阐述的 SAR 抛物线指标相比,布林线指标能让交易者找出新趋势并加以利用。此外,因为可以辨别出反转形态,所以能快速退出趋势。仅仅三条线是如何做到这点的?非常简单:

布林带中轨 (MBB) 的魔力

MBB 是组成布林线指标的三条轨线中最重要的一条,有点像安德鲁干草叉指标中中线的作用(随后将在我们的项目中进一步阐述)。干草叉指标中的三条线都是直线,而布林线指标因或多或少代表移动平均线,所以并非直线。

运用 MBB 时,须等待价格在布林带(MBB 与 UBB 之间)的上端行进,因为这表示看涨趋势。同理,当价格始终位于布林线指标(MBB 与 LBB 之间)下端时,则形成看跌趋势。艾略特波浪理论称,每个市场行为都会产生反应;或是市场每波动一次,都伴随有调整。我们需要找出 MBB 调整。这样,当价格进入 MBB 线时,即可在看涨趋势买入,看跌时卖出。上图向我们展示了做多侧的明确进入点位,这时价格呈看涨趋势。持续时间越长,则进入越强势。由于 MBB 是指数移动平均线,它始终在适应当前价格,所以交易者能从形成的每根新蜡烛线中提前知悉其点位。交易者等待进入新交易时可以利用挂单。提交挂单前须注意一点:如果前面形成了反转形态,请略过。这张图还给出了三个不同反转点。它们分别是什么,怎么运用?

利用布林线指标找出反转形态

要找出当前趋势中的反转形态甚至是新趋势起点,须用到 UBB 和 LBB。交易者找到一根顶部接近 LBB(即将形成新看跌趋势)或高出 UBB(即将形成新看涨趋势)的蜡烛线。上图展示了三个反转点。第一个点最终是虚晃一招,因为价格接近 LBB 下方后回撤到 MBB。根据上文所述的相同原理,触及 MBB 时须进行空头交易。当收盘价高于 UBB 时应当空头止损,因为在之前趋势方向形成了另一个反转点。但这时不建议再在做多侧交易,因为价格提早形成反转看跌形态表示上行趋势正失去动力。不用说,几根蜡烛线过后会出现另一个看跌反转形态,这时形成一个新看跌趋势。从此时起,交易者应当采用上文所述方法利用新形成的趋势。

该指标的魅力在于,这里讲述的两种方法适用于应用该指标的任何时间范围。如果您是抢帽子者,那么不论将布林线指标用于 1 分钟图还是 5 分钟图,布林线指标都有用;同样的原理适用于任何时间范围。如果您是波段交易者,交易的时间范围从几小时、几天到几周不等,那么可以利用布林线指标轻松找到反转点和点位以加入趋势当中。不论您是哪种交易者或采用哪种交易风格,布林线指标都是您的交易工具包中的一个宝贵工具。
