四周规则(海龟交易法)
关键字：四周规则(海龟交易法)
四周规则是什么？四周规则又称为海龟交易法，它是行内炒金人士不常用到的一种盘面分析方法，一般适用于偏向中期的贵金属持仓计划。下面大田环球贵金属小编为各位炒金新手介绍四周规则的分析方法。
一、四周规则的定义
四周规则适用于时间单位按一周结算的K线图，即对应的技术走势图是周K线图，通常K线运行均有惯性迹象，例如前一根为阳线或阴线，后一根在无关键利好或利空消息引导下，价格一般会延续前一日的走势，行情一般受重要消息面影响之后，最长会有一个月的发酵时间，即四个交易周的走势变化。
二、四周规则的用法
1、 金价大于前4根周K线最高价
在周K线图中，若开出的新一根周线最高价超过了前四根周K线的最高价，投资者可尝试进场计划布局多单。
2、 金价小于前4根周K线最低价
在周K线图中，若开出的新一根周线最低价超过了前四根周K线的最低价，投资者可尝试进场计划布局空单。
三、四周规则的有效性
1、 四周规则的假突破特征
新一根周K线高于或低于前四根K线之后，后一根新的周K线有可能与前一根周K线形成看涨或看跌吞没形态，此为四周规则的假突破特征，投资者此时应暂作观望，之前创建的仓位最好在后一根周K线已成定局之前平掉，以免招致更大亏损风险。
2、 四周规则的真突破特征
4根周K线形成之后，连续两根新周K线大致跟随原来单边方向运行，即使K线形态实体较短，形成了倾向反转的星体状K线，我们也可顺应大势建立交易单，并于持单后确立最佳平仓时机，一般两根新周K线形成之后，反转风险也随之增大，此时可考虑平仓。
3、 四周规则与技术指标共振
当新周K线明显与前4周K线明显呈现单边格局时，若该时段相关技术指标也配合行情发出一致单边信号，K线后市单边走向可能性将大为增加，如经历四周K线走势变化后，新开周K线形成阴线，且最低价低于前四周K线的最低价，若该时段均线MA5和MA10构成死叉，金价将开启一定幅度的下行空间。
