For new rising trend, to calculate the next SAR, the acceleration factor is multiplied by the difference between the current high for the new trend and the prior period&acirc;&euro;&trade;s SAR. This is then added to the prior period&acirc;&euro;&trade;s SAR.<\/p>\n\n\n\n\n\n<p>The Parabolic Time\/Price System is a trading system that calculates stop and reverse values as a function of price and time. When a position is initiated, the stop is set at a price above or below current action based on previous price swings. The stop is then moved in the direction of price activity based on an accelerator formula. This allows a new trend to become established without stopping out correct positions due to the normal volatility associated with changes in trend.<\/p>\n\n\n\n\n\n<p>When the price action turns and hits the trailing parabolic stop, the position is reversed and a new stop is calculated. The point at which the position is reversed is called a stop-and-reverse (SAR). The system is always long or short, never neutral.<\/p>\n\n\n--> <\/p>\n<p><img decoding=\"async\" class=\"img-responsive\" src=\"https:\/\/library-staging.tradingtechnologies.com\/wp-content\/uploads\/2026\/06\/parabolic-sar-2.png\" alt=\"\"><\/p>\n<h2>Configuration Options<\/h2>\n<p><img decoding=\"async\" class=\"img-responsive\" src=\"https:\/\/library-staging.tradingtechnologies.com\/wp-content\/uploads\/2026\/06\/parabolic-sar-3.png\" alt=\"\"><\/p>\n<ul>\n<li><strong>Minimum AF<\/strong> (\u6700\u5c0fAF): \u6700\u5c0f\u52a0\u901f\u56e0\u5b50<\/li>\n<li><strong>Maximum AF<\/strong> (\u6700\u5927AF): \u6700\u5927\u52a0\u901f\u56e0\u5b50<\/li>\n<li><strong>Color Selectors<\/strong> (\u914d\u8272\u30bb\u30ec\u30af\u30bf\u30fc): \u30b0\u30e9\u30d5\u8981\u7d20\u306b\u4f7f\u7528\u3059\u308b\u914d\u8272\u3002<\/li>\n<li><strong>Display Axis Label<\/strong> (\u8ef8\u30e9\u30d9\u30eb\u306e\u8868\u793a): Y \u8ef8\u306b\u6700\u65b0\u5024\u3092\u8868\u793a\u3059\u308b\u304b\u3069\u3046\u304b\u3002<\/li>\n<\/ul>\n<p><a name=\"Formula\"><\/a><\/p>\n<h2 class=\"Blurb\">\u6570\u5f0f<\/h2>\n<p class=\"BodyOther\"><span class=\"ListItems\">\u65b0\u898f\u306e\u30ed\u30f3\u30b0 \u30dd\u30b8\u30b7\u30e7\u30f3\u306e\u5834\u5408<\/span>:<\/p>\n<p class=\"BodyOther\">[ SAR = P + (A * ( H &#8211; P )) ]<\/p>\n<p class=\"BodyChapterLevel\">\u5b9a\u7fa9\u306f\u4ee5\u4e0b\u306e\u3068\u304a\u308a\u3067\u3059\u3002<\/p>\n<ul list-style-type=\"\">\n<li>SAR = \u30dd\u30b8\u30b7\u30e7\u30f3\u3092\u30ed\u30f3\u30b0\u304b\u3089\u30b7\u30e7\u30fc\u30c8\u306b\u8ee2\u63db\u3059\u308b\u305f\u3081\u306e\u3001\u30b9\u30c8\u30c3\u30d7\u3068\u9014\u8ee2\uff08\u3069\u3066\u3093\uff09= Stop And Reverse\u306e\u4fa1\u683c<\/li>\n<li>P = \u00a0\u524d\u306e\u671f\u9593\u306e SAR<\/li>\n<li>A = \u52a0\u901f\u56e0\u5b50 <!--A begins at .02 for the period immediately after the initial SAR\nbuy stop order opens the current long trade.
