炒黄金技术指标：SAR指标
关键字：炒黄金技术指标：SAR指标
炒黄金SAR技术指标是一种趋势指标，主要用于研究中短期趋势，中文名为抛物线指标，该指标以黄金价格和时间长度作为参考变量，所以研究方法与MA线类似，但和MA线不同的是，MA线是以一定时期内K线组合的收盘价进行加权平均统计的一种线段，而SAR线的计算方式与MA线不同，它是利用抛物线运动的方式随时调整SAR点位的位置的一种技术分析工具。
由上文得知，SAR技术指标的算法比较复杂，此处不作详细的公式介绍，我们仅需了解如何应用SAR进行黄金投资分析，包括SAR指标在K线图盘面上的意义，以及SAR指标与K线图如何结合指导交易方向即可。
SAR指标在K线图盘面上，K线组合形成的每一浪之间用弧线来表现，当K线位于SAR线上方时，反映盘面以多头力量为主，当K线位于SAR线下方时，反映盘面以空头力量为主。
下面我们来看一下SAR指标如何与K线图结合指导金价行情，
1、 当K线向上突破SAR指标时，此时为多头行情；当K线向下突破SAR指标时，此时为空头行情。
2、 K线突破SAR指标以后，SAR指标跟随K线走势同向运行，那么该交易方向的动力将增强，反映出SAR线的助涨助跌作用，此时是把握交易入市点位的好时机，例如SAR指标跟随K线一起向上运行，那么可以确认为单边的上涨行情。
3、 当K线发生冲高回落时，SAR线也会从上升转变为下行，此时SAR指标附近通常会出现一个明显的支撑点位，这将起到防止K线再度下跌的作用，也是多单进场短线交易的时机。
一般来说，判断金价的区间震荡高低点，炒黄金SAR技术指标和长期均线相结合起来运用更佳，例如跟100日或60日均线相结合，更明确地了解支撑点和阻力点的具体位置及反转力度，当长期均线和SAR指标走势同向时，其高低点位置的可靠程度就越大，令炒金的获利目标更为明朗，大大增加了套利的可能。
