现货黄金BOLL指标原理
关键字:现货黄金BOLL指标原理
现货黄金BOLL指标又称现货黄金布林带指标,它是一种基于主盘面中的K线图运行走势,结合统计学上的标准差原理所设计出来的一种趋势型指标,在大田环球贵金属平台中,技术指标中的趋势指标里“B”字开头的就是BOLL(布林带)指标。下面我们具体地了解一下,现货黄金BOLL(布林带)指标的原理是什么。
1、 BOLL(布林带)主要由三条轨道组成,位于K线上方的轨道称为上轨,位于K线中间位置的轨道称为中轨,位于K线下方的轨道称为下轨。三条轨道分别对K线走势产生相应的支撑或阻力作用。
2、 一般地,BOLL(布林带)上轨将对现货黄金价格构成打压,也就是阻力,当K线触及BOLL(布林带)上轨时,金价会发生高位回落。而BOLL(布林带)中轨将对现货黄金价格产生推波助澜的作用,这要根据K线所在通道位置来确定BOLL(布林带)中轨对现货黄金价格是助涨还是助跌的推动。BOLL(布林带)下轨将对现货黄金构成提振,也就是支撑,当K线触及BOLL(布林带)下轨时,金价会发生止跌回升。
3、 BOLL(布林带)指标的运行过程中,K线一般都会在BOLL(布林带)指标形成的通道内运行,其中上轨和中轨之间为上方通道,中轨和下轨之间为下方通道,当K线位于BOLL(布林带)的上方通道时,BOLL(布林带)中轨起到助涨作用,限制金价的跌幅;当K线位于BOLL(布林带)下方通道时,BOLL(布林带)中轨起到助跌作用,限制金价的涨幅。
4、 当BOLL(布林带)指标出现开口收缩时,则为大行情的前期征兆,随着大行情的逐步逼近,BOLL(布林带)指标开口剧烈扩张,向上扩张的BOLL(布林带)指标为单边上涨行情,向下扩张的BOLL(布林带)指标为单边下跌行情,若BOLL(布林带)指标开口收缩,反映该次大行情即将进入尾声,金价呈现新一个区间中的横盘整理。
5、 当K线长期运行于BOLL(布林带)中轨时,反映的是区间窄幅震荡行情,此时多空力量平分秋色,行情尚无明确的做单指引。
6、 K线的运行趋势能改变布林轨道的移动点位,当K线向上运行时,将会推动BOLL(布林带)指标向上移动;同理,当K线向下运行时,将会推动BOLL(布林带)指标向下移动。因此,当BOLL指标(布林带)上轨受K线上行而向上运行时,可以判断为看多行情,当BOLL指标(布林带)下轨受K线下行而向下运行时,可以判断为看空行情。
综上所述,现货黄金BOLL(布林带)指标是一种趋势型技术指标,它是由贯穿现货黄金行情最高价、平均价及最低价的三条线段组合而成,三条线段和线段之间构成的通道,均对现货黄金价格构成支撑或阻力作用,BOLL(布林带)指标的开口大小能反映出行情趋向单边还是盘整,且金价与BOLL(布林带)指标的上轨或下轨同向时,则为明显的单边行情。
