抛物线SAR指标:描述,设置和应用

抛物线SAR系统是为分析市场趋势而设计的技术指标。 当市场看跌趋势盛行时,指标通常位于图表价格之上。 反之亦然,当市场处于牛市的控制之下时,抛物线SAR仍然低于价格。

抛物线SAR

抛物面SAR在价格横穿其线后发生变化。 因此,该指标的进一步读数将位于价格水平的另一侧。 与此同时,前一时期的高点和低点成为起点。 抛物线SAR的反转表明趋势已经终止,价格已经进入平淡的市场。

该指标使交易者能够尽可能准确地定义入口点。 如果价格跌破指标线,则应该将其视为关闭多头交易的信号。 如果价格高于指标,那么有必要关闭空头交易。 抛物线SAR常常作为追踪止损。

对于长期交易,无论价格走向哪个方向,抛物线SAR的读数总是增加。 价格走势的节奏会影响指标线的转变。

计算

SAR(i) = SAR(i-1)+ACCELERATION*(EPRICE(i-1)-SAR(i-1))

Where:

SAR(i-1) - 是前一栏中指标的值;

ACCELERATION - 是加速因子;

EPRICE(i-1) - 是上一期间的最高(最低)价格(EPRICE =多头高位,EPRICE =空头低位)。

如果当前柱形图的价格高于先前看涨的价格,则指标值会增加,反之亦然。 加速因子(ACCELERATION)将同时加倍,这将导致抛物线SAR和价格走到一起。 换句话说,价格上涨或下跌越快,指标越接近价格。
